PREFACE
This book contains the substance, and for the most part the words, of
a course of public lectures delivered during the first three months of
1919. The original division into lectures has been dropped, the matter
being more conveniently redivided into chapters.
The audience to whom the lectures were delivered was composed of
members of the general public, and not only of students. For the most
part they possessed no previous knowledge of philosophy. Hence this
book, like the original lectures, assumes no previous special
knowledge, though it assumes, of course, a state of general education
in the reader. Technical philosophical terms are carefully explained
when first introduced; and a special effort has been made to put
philosophical ideas in the clearest way possible. But it must be
remembered that many of the profoundest as well as the most difficult
of human conceptions are to be found in Greek philosophy. Such ideas
are difficult in themselves, however clearly expressed. No amount of
explanation can ever render them anything but difficult to the
unsophisticated mind, and anything in the nature of "philosophy made
easy" is only to be expected from quacks and charlatans.
Greek philosophy is not, even now, antiquated. It is not from the
point of view of an antiquary or historian {vi} that its treasures are
valuable. We are dealing here with living things, and not with mere
dead things--not with the dry bones and debris of a bygone age. And I
have tried to lecture and write for living people, and not for mere
fossil-grubbers. If I did not believe that there is to be found here,
in Greek philosophy, at least a measure of the truth, the truth that
does not grow old, I would not waste five minutes of my life upon it.
"We do not," says a popular modern writer, [Footnote 1] "bring the
young mind up against the few broad elemental questions that are the
_questions of metaphysics_ .... We do not make it discuss, correct it,
elucidate it. That was the way of the Greeks, and we worship that
divine people far too much to adopt their way. No, we lecture to our
young people about not philosophy but philosophers, we put them
through book after book, telling how other people have discussed these
questions. We avoid the questions of metaphysics, but we deliver
semi-digested half views of the discussions of, and answers to these
questions made by men of all sorts and qualities, in various remote
languages and under conditions quite different from our own. . . . It
is as if we began teaching arithmetic by long lectures upon the origin
of the Roman numerals, and then went on to the lives and motives of
the Arab mathematicians in Spain, or started with Roger Bacon in
chemistry, or Sir Richard Owen in comparative anatomy .... It is time
the educational powers began to realise that the questions of
metaphysics, the elements of philosophy, are, here and now to be done
afresh in each mind .... What is wanted is philosophy, and not a
shallow smattering of the history of philosophy ... {vii} The proper
way to discuss metaphysics, like the proper way to discuss mathematics
or chemistry, is to discuss the accumulated and digested product of
human thought in such matters."
[Footnote 1: H. G. Wells in "First and Last Things."]
Plausible words these, certain to seem conclusive to the mob,
notwithstanding that for one element of truth they contain nine of
untruth! The elements of truth are that our educational system
unwarrantably leaves unused the powerful weapon of oral discussion--so
forcibly wielded by the Greeks--and develops book knowledge at the
expense of original thought. Though even here it must be remembered,
as regards the Greeks, (1) that if they studied the history of
philosophy but little, it was because there was then but little
history of philosophy to study, and (2) that if anyone imagines that
the great Greek thinkers did not fully master the thought of their
predecessors before constructing their own systems, he is grievously
mistaken, and (3) that in some cases the over-reliance on oral
discussion--the opposite fault to ours--led to intellectual
dishonesty, quibbling, ostentation, disregard of truth, shallowness,
and absence of all principle; this was the case with the Sophists.
As to the comparisons between arithmetic and philosophy, chemistry and
philosophy, etc., they rest wholly upon a false parallel, and involve
a total failure to comprehend the nature of philosophic truth, and its
fundamental difference from arithmetical, chemical, or physical truth.
If Eratosthenes thought the circumference of the earth to be so much,
whereas it has now been discovered to be so much, then the later
correct view simply cancels and renders nugatory the older view.
{viii} The one is correct, the other incorrect. We can ignore and
forget the incorrect view altogether. But the development of
philosophy proceeds on quite other principles. Philosophical truth is
no sum in arithmetic to be totted up so that the answer is thus
formally and finally correct or incorrect. Rather, the philosophical
truth unfolds itself, factor by factor, in time, in the successive
systems of philosophy, and it is only in the complete series that the
complete truth is to be found. The system of Aristotle does not simply
cancel and refute that of Plato. Spinoza does not simply abolish
Descartes. Aristotle completes Plato, as his necessary complement.
Spinoza does the same for Descartes. And so it is always. The
calculation of Eratosthenes is simply wrong, and so we can afford to
forget it. But the systems of Plato, Aristotle, Spinoza, Leibniz,
etc., are all alike factors of the truth. They are as true now as they
were in their own times, though they are not, and never were, the
whole truth. And therefore it is that they are not simply wrong, done
with, finished, ended, and that we cannot afford to forget them.
Whether it is not possible to bring the many lights to a single focus,
to weld the various factors of the truth into a single organic whole
or system, which should thus be the total result to date, is another
question. Only one such attempt has ever been made, but no one will
pretend that it is possible to understand it without a thorough
knowledge of all previous systems, a knowledge, in fact, of the
separate factors of the truth before they are thus combined into a
total result. Besides, that attempt, too, is now part of the history
of philosophy!
Hence any philosophical thinking which is not founded {ix} upon a
thorough study of the systems of the past will necessarily be shallow
and worthless. And the notions that we can dispense with this study,
and do everything out of our own heads, that everyone is to be his own
philosopher, and is competent to construct his own system in his own
way--such ideas are utterly empty and hollow. Of these truths, indeed,
we see a notable example in what the writer just quoted styles his
"metaphysic." This so-called metaphysic is wholly based upon the
assumption that knowledge and its object exist, each on its own
account, external to one another, the one here, the other there over
against it, and that knowledge is an "instrument" which in this
external manner takes hold of its object and makes it its own. The
very moment the word "instrument" is used here, all the rest,
including the invalidity of knowledge, follows as a matter of course.
Such assumption then--that knowledge is an "instrument"--our writer
makes, wholly uncritically, and without a shadow of right. He gives no
sign that it has ever even occurred to him that this is an assumption,
that it needs any enquiry, or that it is possible for anyone to think
otherwise. Yet anyone who will take the trouble, not merely
superficially to dip into the history of philosophy, but thoroughly to
submit himself to its discipline, will at least learn that this is an
assumption, a very doubtful assumption, too, which no one now has the
right to foist upon the public without discussion as if it were an
axiomatic truth. He might even learn that it is a false assumption.
And he will note, as an ominous sign, that the subjectivism which
permeates and directs the whole course of Mr. Wells's thinking is
identical in character with that {x} subjectivism which was the
essential feature of the decay and _downfall_ of the Greek philosophic
spirit, and was the cause of its final _ruin_ and _dissolution_.
I would counsel the young, therefore, to pay no attention to plausible
and shallow words such as those quoted, but, before forming their own
philosophic opinions, most thoroughly and earnestly to study and
master the history of past philosophies, first the Greek and then the
modern. That this cannot be done merely by reading a modern resume of
that history, but only by studying the great thinkers in their own
works, is true. But philosophical education must begin, and the
function of such books as this, is, not to complete it, but to begin
it; and to obtain first of all a general view of what must afterwards
be studied in detail is no bad way of beginning. Moreover, the study
of the development and historical connexions of the various
philosophies, which is not found in the original writings themselves,
will always provide a work for histories of philosophy to do.
Two omissions in this book require, perhaps, a word of explanation.
Firstly, in dealing with Plato's politics I have relied on the
"Republic," and said nothing of the "Laws." This would not be
permissible in a history of political theories, nor even in a history
of philosophy which laid any special emphasis on politics. But, from
my point of view, politics lie on the extreme outer margin of
philosophy, so that a more slender treatment of the subject is
permissible. Moreover, the "Republic," whether written early or late,
expresses, in my opinion, the views of Plato, and not those of
Socrates, and it still remains the outstanding, typical, and
characteristic {xi} expression of the Platonic political ideal,
however much that ideal had afterwards to be modified by practical
considerations.
Secondly, I have not even mentioned the view, now held by some, that
the theory of Ideas is really the work of Socrates, and not of Plato,
and that Plato's own philosophy consisted in some sort of esoteric
number-theory, combined with theistic and other doctrines. I can only
say that this theory, as expounded for example by Professor Burnet,
does not commend itself to me, that, in fact, I do not believe it, but
that, it being impossible to discuss it adequately in a book of this
kind, I have thought that, rather than discuss it inadequately, it
were better to leave it alone altogether. Moreover, it stands on a
totally different footing from, say, Professor Burnet's interpretation
of Parmenides, which I have discussed. That concerned the
interpretation of the true meaning of a philosophy. This merely
concerns the question who was the author of a philosophy. That was a
question of principle, this merely of personalities. That was of
importance to the philosopher, this merely to the historian and
antiquary. It is like the Bacon-Shakespeare question, which no lover
of drama, as such, need concern himself with at all. No doubt the
Plato-Socrates question is of interest to antiquarians, but after all,
fundamentally, it does not matter who is to have the credit of the
theory of Ideas, the only essential thing for us being to understand
that theory, and rightly to apprehend its value as a factor of the
truth. This book is primarily concerned with philosophical ideas,
their truth, meaning, and significance, and not with the rights and
wrongs of antiquarian disputes. It does indeed purport to {xii} be a
_history_, as well as a discussion of philosophic conceptions. But
this only means that it takes up philosophical ideas in their
historical sequence and connexions, and it does this only because the
conceptions of evolution in philosophy, of the onward march of thought
to a determined goal; of its gradual and steady rise to the supreme
heights of idealism, its subsequent decline, and ultimate collapse,
are not only profoundly impressive as historical phenomena, but are of
vital importance to a true conception of philosophy itself. Were it
not for this, Mr. Wells would, I think, be right, and I for one should
abandon treatment in historical order altogether. Lastly, I may remark
that the description of this book as a _critical_ history means that it
is, or attempts to be critical, not of dates, texts, readings, and the
like, but of philosophical conceptions.
I owe a debt of thanks to Mr. F. L. Woodward, M.A., late principal of
Mahinda College, Galle, Ceylon, for assisting me in the compilation of
the index of names, and in sundry other matters.

A CRITICAL HISTORY OF GREEK PHILOSOPHY
CHAPTER I
THE IDEA OF PHILOSOPHY IN GENERAL.
THE ORIGINS AND DEVELOPMENT OF GREEK PHILOSOPHY
It is natural that, at the commencement of any study, one should be
expected to say what the subject-matter of that study is. Botany is
the knowledge of plants, astronomy of the heavenly bodies, geology of
the rocks of the earth's crust. What, then, is the special sphere of
philosophy? What is philosophy about? Now it is not as easy to give a
concise definition of philosophy, as it is of the other sciences. In
the first place, the content of philosophy has differed considerably
in different periods of history. In general the tendency has been to
narrow down the scope of the subject as knowledge advanced, to exclude
from philosophy what was formerly included in it. Thus in the time of
Plato, physics and astronomy were included as parts of philosophy,
whereas now they constitute separate sciences. This, however, is not
an insurmountable difficulty. What chiefly militates against the
effort to frame a definition is that the precise content of philosophy
is differently viewed by different schools of thought. Thus a
definition of {2} philosophy which a follower of Herbert Spencer might
frame would be unacceptable to an Hegelian, and the Hegelian
definition would be rejected by the Spencerian. If we were to include
in our definition some such phrase as "the knowledge of the Absolute,"
while this might suit some philosophers, others would deny that there
is any Absolute at all. Another school would say that there may be an
Absolute, but that it is unknowable, so that philosophy cannot be the
knowledge of it. Yet another school would tell us that, whether there
is or is not an Absolute, whether it is or is not knowable, the
knowledge of it is in any case useless, and ought not to be sought.
Hence no definition of philosophy can be appreciated without some
knowledge of the special tenets of the various schools. In a word, the
proper place to give a definition is not at the beginning of the study
of philosophy, but at the end of it. Then, with all views before us,
we might be able to decide the question.
I shall make no attempt, therefore, to place before you a precise
definition. But perhaps the same purpose will be served, if I pick out
some of the leading traits of philosophy, which serve to distinguish
it from other branches of knowledge, and illustrate them by
enumerating--but without any attempt at completeness--some of the
chief problems which philosophers have usually attempted to solve. And
firstly, philosophy is distinguished from other branches of knowledge
by the fact that, whereas these each take some particular portion of
the universe for their study, philosophy does not specialize in this
way, but deals with the universe as a whole. The universe is one, and
ideal knowledge of it would be one; but the principles of
specialization and division of {3} labour apply here as elsewhere, and
so astronomy takes for its subject that portion of the universe which
we call the heavenly bodies, botany specializes in plant life,
psychology in the facts of the mind, and so on. But philosophy does
not deal with this or that particular sphere of being, but with being
as such. It seeks to see the universe as a single co-ordinated system
of things. It might be described as the science of things in general.
The world in its most universal aspects is its subject. All sciences
tend to generalize, to reduce multitudes of particular facts to single
general laws. Philosophy carries this process to its highest limit. It
generalizes to the utmost. It seeks to view the entire universe in the
light of the fewest possible general principles, in the light, if
possible, of a single ultimate principle.
It is a consequence of this that the special sciences take their
subject matter, and much of their contents, for granted, whereas
philosophy seeks to trace everything back to its ultimate grounds. It
may be thought that this description of the sciences is incorrect. Is
not the essential maxim of modern science to assume nothing, to take
nothing for granted, to assert nothing without demonstration, to prove
all? This is no doubt true within certain limits, but beyond those
limits it does not hold good. All the sciences take quite for granted
certain principles and facts which are, for them, ultimate. To
investigate these is the portion of the philosopher, and philosophy
thus takes up the thread of knowledge where the sciences drop it. It
begins where they end. It investigates what they take as a matter of
course.
Let us consider some examples of this. The science of geometry deals
with the laws of space. But it takes {4} space just as it finds it in
common experience. It takes space for granted. No geometrician asks
what space is. This, then, will be a problem for philosophy. Moreover,
geometry is founded upon certain fundamental propositions which, it
asserts, being self-evident, require no investigation. These are
called "axioms." That two straight lines cannot enclose a space, and
that equals being added to equals the results are equal, are common
examples. Into the ground of these axioms the geometrician does not
enquire. That is the business of philosophy. Not that philosophers
affect to doubt the truth of these axioms. But surely it is a very
strange thing, and a fact quite worthy of study, that there are some
statements of which we feel that we must give the most laborious
proofs, and others in the case of which we feel no such necessity. How
is it that some propositions can be self-evident and others must be
proved? What is the ground of this distinction? And when one comes to
think of it, it is a very extraordinary property of mind that it
should be able to make the most universal and unconditional statements
about things, without a jot of evidence or proof. When we say that two
straight lines cannot enclose a space, we do not mean merely that this
has been found true in regard to all the particular pairs of straight
lines with which we have tried the experiment. We mean that it never
can be and never has been otherwise. We mean that a million million
years ago two straight lines did not enclose a space, and that it will
be the same a million million years hence, and that it is just as true
on those stars, if there are any, which are invisible even to the
greatest telescopes. But we have no experience of what will {5} happen
a million million years hence, or of what can take place among those
remote stars. And yet we assert, with absolute confidence, that our
axiom is and must be equally true everywhere and at all times.
Moreover, we do not found this on probabilities gathered from
experience. Nobody would make experiments or use telescopes to prove
such axioms. How is it that they are thus self-evident, that the mind
can make these definite and far-reaching assertions without any
evidence at all? Geometricians do not consider these questions. They
take the facts for granted. To solve these problems is for philosophy.
Again, the physical sciences take the existence of matter for granted.
But philosophy asks what matter is. At first sight it might appear
that this question is one for the physicist and not the philosopher.
For the problem of "the constitution of matter" is a well-known
physical problem. But a little consideration will show that this is
quite a different question from the one the philosopher propounds. For
even if it be shown that all matter is ether, or electricity, or
vortex-atoms, or other such, this does not help us in our special
problem. For these theories, even if proved, only teach us that the
different kinds of matter are forms of some one physical existence.
But what we want to know is what physical existence itself is. To
prove that one kind of matter is really another kind of matter does
not tell us what is the essential nature of matter. That, therefore,
is a problem, not of science, but of philosophy.
In the same way, all the sciences take the existence of the universe
for granted. But philosophy seeks to know why it is that there is a
universe at all. Is it {6} true, for example, that there is some
single ultimate reality which produces all things? And if so, what
sort of a reality is it? Is it matter, or mind, or something different
from both? Is it good or evil? And if it is good, how is it that there
is evil in the world?
Moreover every science, except the purely mathematical sciences,
assumes the truth of the law of causation. Every student of logic
knows that this is the ultimate canon of the sciences, the foundation
of them all. If we did not believe in the truth of the law of
causation, namely, that everything which has a beginning has a cause,
and that in the same circumstances the same things invariably happen,
all the sciences would at once crumble to dust. In every scientific
investigation, this truth is assumed. If we ask the zoologist how he
knows that all camels are herbivorous, he will no doubt point in the
first instance to experience. The habits of many thousands of camels
have been observed. But this only proves that those particular camels
are herbivorous. How about the millions that have never been observed
at all? He can only appeal to the law of causation. The camel's
structure is such that it cannot digest meat. It is a case of cause
and effect. How do we know that water always freezes at 0° centigrade
(neglecting questions of pressure, etc.)? How do we know that this is
true at those regions of the earth where no one has ever been to see?
Only because we believe that in the same circumstances the same thing
always happens, that like causes always produce like effects. But how
do we know the truth of this law of causation itself? Science does not
consider the question. It traces its assertions back to this law, but
goes no {7} further. Its fundamental canon it takes for granted. The
grounds of causation, why it is true, and how we know it is true, are,
therefore, philosophical questions.
One may be tempted to enquire whether many of these questions,
especially those connected with the ultimate reality, do not transcend
human faculties altogether, and whether we had not better confine our
enquiries to matters that are not "too high for us." One may question
whether it is possible for finite minds to comprehend the infinite.
Now it is very right that such questions should be asked, and it is
essential that a correct answer should be found. But, for the present,
there is nothing to say about the matter, except that these questions
themselves constitute one of the most important problems of
philosophy, though it is one which, as a matter of fact, has scarcely
been considered in full until modern times. The Greeks did not raise
the question. [Footnote 2] And as this is itself one of the problems
of philosophy, it will be well to start with an open mind. The
question cannot be decided offhand, but must be thoroughly
investigated. That the finite mind of man cannot understand the
infinite is one of those popular dogmatic assertions, which are
bruited about from mouth to mouth, as if they were self-evident, and
so come to tyrannize over men's minds. But for the most part those who
make this statement have never thoroughly sifted the grounds of it,
but simply take it as something universally admitted, and trouble no
further about it. But at the very least we should first know exactly
what {8} we mean by such terms as "mind," "finite," and "infinite."
And we shall not find that our difficulties end even there.
[Footnote 2: The reasoning of the Sceptics and others no doubt
involved this question. But they did not consider it in its peculiar
modern form.]
Philosophy, then, deals with the universe as a whole; and it seeks to
take nothing for granted. A third characteristic may be noted as
especially important, though here no doubt we are trenching upon
matters upon which there is no such universal agreement. Philosophy is
essentially an attempt to rise from sensuous to pure, that is,
non-senuous, thought. This requires some explanation.
We are conscious, so to speak, of two different worlds, the external
physical world and the internal mental world. If we look outwards we
are aware of the former, if we turn our gaze inwards upon our own
minds we become aware of the latter. It may appear incorrect to say
that the external world is purely physical, for it includes other
minds. I am aware of your mind, and this is, to me, part of the world
which is external to me. But I am not now speaking of what we know by
inference, but only of what we directly perceive. I cannot directly
perceive your mind, but only your physical body. In the last resort it
will be found that I am aware of the existence of your mind only by
inference from perceived physical facts, such as the movements of your
body and the sounds that issue from your lips. The only mind which I
can immediately perceive is my own. There is then a physical world
external to us, and an internal mental world.
Which of these will naturally be regarded as the most real? Men will
regard as the most real that which is the most familiar, that which
they came first into {9} contact with, and have most experience of.
And this is unquestionably the external material world. When a child
is born, it turns its eyes to the light, which is an external physical
thing. Gradually it gets to know different objects in the room. It
comes to know its mother, but its mother is, in the first instance, a
physical object, a body. It is only long afterwards that its mother
becomes for the child a mind or a soul. In general, all our earliest
experiences are of the material world. We come to know of the mental
world only by introspection, and the habit of introspection comes in
youth or manhood only, and to many people it hardly comes at all. In
all those early impressionable years, therefore, when our most durable
ideas of the universe are formed, we are concerned almost exclusively
with the material world. The mental world with which we are much less
familiar consequently tends to appear to all of us something
comparatively unreal, a world of shadows. The bent of our minds
becomes materialistic.
What I have said of the individual is equally true of the race.
Primitive man does not brood over the facts of his own mind. Necessity
compels him to devote most of his life to the acquisition of food, and
to warding off the dangers which continually threaten him from other
physical objects. And even among ourselves, the majority of men have
to spend most of their time upon considering various aspects of things
external to them. By the individual training of each man, and by long
hereditary habit, then, it comes about that men tend to regard the
physical world as more real than the mental.
{10}
Abundant evidences of this are to be found in the structure of human
language. We seek to explain what is strange by means of what is
well-known. We try to express the unfamiliar in terms of the familiar.
We shall find that language always seeks to express the mental by the
analogy of the physical. We speak of a man as a "clear" thinker.
"Clear" is an attribute of physical objects. Water is clear if it has
no extraneous matter in it. We say that a man's ideas are "luminous,"
thus taking a metaphor from physical light. We talk of having an idea
"at the back of the mind." "At the back of"? Has the mind got a front
and a back? We are thinking of it as if it were a physical thing in
space. We speak of mental habits of "attention." "Attention" means
stretching or turning the mind in a special direction. We "reflect."
"Reflection" means bending our thoughts back upon themselves. But,
literally speaking, only physical objects can be stretched, turned,
and bent. Whenever we wish to express something mental we do it by a
physical analogy. We talk of it in terms of physical things. This
shows how deep-rooted our materialism is. If the mental world were
more familiar and real to us than the material, language would have
been constructed on the opposite principle. The earliest words of
language would have expressed mental facts, and we should afterwards
have tried to express physical things by means of mental analogies.
In the East one commonly hears Oriental idealism contrasted with
Western materialism. Such phrases may possess a certain relative
truth. But if they mean that there is in the East, or anywhere else in
the world, {11} a race of men who are naturally idealists, they are
nonsense. Materialism is ingrained in all men. We, Easterns or
Westerns, are born materialists. Hence when we try to think of objects
which are commonly regarded as non-material, such as God or the soul,
it requires continual effort, a tremendous struggle, to avoid
picturing them as material things. It goes utterly against the grain.
Perhaps hundreds of thousands of years of hereditary materialism are
against us. The popular idea of ghosts will illustrate this. Those who
believe in ghosts, I suppose, regard them as some sort of disembodied
souls. The pictures of ghosts in magazines show them as if composed of
matter, but matter of some _thin_ kind, such as vapour. Certain Indian
systems of thought, which are by way of regarding themselves as
idealistic, nevertheless teach that thought or mind is an extremely
subtle kind of matter, far subtler than any ever dealt with by the
physicist and chemist. This is very interesting, because it shows that
the authors of such ideas feel vaguely that it is wrong to think of
thought as if it were matter, but being unable to think of it in any
other way, owing to man's ingrained materialism, they seek to palliate
their sin by making it thin matter. Of course this is just as absurd
as the excuse made by the mother of an illegitimate child, that it was
a very small one. This thin matter is just as material as lead or
brass. And such systems are purely materialistic. But they illustrate
the extraordinary difficulty that the ordinary mind experiences in
attempting to rise from sensuous to non-sensuous thinking. They
illustrate the ingrained materialism of man.
This natural human materialism is also the cause {12} of mysticism and
symbolism. A symbolic thought necessarily contains two terms, the
symbol and the reality which it symbolizes. The symbol is always a
sensuous or material object, or the mental image of such an object,
and the reality is always something non-sensuous. Because the human
mind finds it such an incredible struggle to think non-sensuously, it
seeks to help itself by symbols. It takes a material thing and makes
it stand for the non-material thing which it is too weak to grasp.
Thus we talk of God as the "light of lights." No doubt this is a very
natural expression of the religious consciousness, and it has its
meaning. But it is not the naked truth. Light is a physical existence,
and God is no more light than he is heat or electricity. People talk
of symbolism as if it were a very high and exalted thing. They say,
"What a wonderful piece of symbolism!" But, in truth symbolism is the
mark of an infirm mind. It is the measure of our weakness and not of
our strength. Its root is in materialism, and it is produced and
propagated by those who are unable to rise above a materialistic
level.
Now philosophy is essentially the attempt to get beyond this sort of
symbolic and mystical thinking, to get at the naked truth, to grasp
what lies behind the symbol as it is in itself. These inferior modes
of thought are a help to those who are themselves below their level,
but are a hindrance to those who seek to reach the highest level of
truth.
It is often said that philosophy is a very difficult and abstruse
subject. Its difficulty lies almost wholly in the struggle to think
non-sensuously. Whenever we {13} come to anything in philosophy that
seems beyond us, we shall generally find that the root of the trouble
is that we are trying to think non-sensuous objects in a sensuous way,
that is, we are trying to form mental pictures and images of them, for
all mental pictures are composed of sensuous materials, and hence no
such picture is adequate for a pure thought. It is impossible to
exaggerate this difficulty. Even the greatest philosophers have
succumbed to it. We shall constantly have to point out that when a
great thinker, such as Parmenides or Plato, fails, and begins to
flounder in difficulties, the reason usually is that, though for a
time he has attained to pure thought, he has sunk back exhausted into
sensuous thinking, and has attempted to form mental pictures of what
is beyond the power of any such picture to represent, and so has
fallen into contradictions. We must keep this constantly in mind in
the study of philosophy.
In modern times philosophy is variously divided, as into metaphysics,
which is the theory of reality, ethics, the theory of the good, and
aesthetics, the theory of the beautiful. Modern divisions do not,
however, altogether fit in with Greek philosophy, and it is better to
let the natural divisions develop themselves as we go on, than to
attempt to force our material into these moulds.
If, now, we look round the world and ask; in what countries and what
ages the kind of thought we have described has attained a high degree
of development, we shall find such a development only in ancient
Greece and in modern Europe. There were great civilizations in Egypt,
China, Assyria, and so on. They produced art and religion, but no
philosophy to speak of. Even {14} ancient Rome added nothing to the
world's philosophical knowledge. Its so-called philosophers, Marcus
Aurelius, Seneca, Epictetus, Lucretius, produced no essentially new
principle. They were merely disciples of Greek Schools, whose writings
may be full of interest and of noble feeling, but whose essential
thoughts contained nothing not already developed by the Greeks.
The case of India is more doubtful. Opinions may differ as to whether
India ever had any philosophy. The Upanishads contain
religio-philosophical thinking of a kind. And later we have the six
so-called schools of philosophy. The reasons why this Indian thought
is not usually included in histories of philosophy are as follows.
Firstly, philosophy in India has never separated itself from religious
and practical needs. The ideal of knowledge for its own sake is rarely
to be found. Knowledge is desired merely as a means towards salvation.
Philosophy and science, said Aristotle, have their roots in
wonder,--the desire to know and understand for the sole sake of
knowing and understanding. But the roots of Indian thought lie in the
anxiety of the individual to escape from the ills and calamities of
existence. This is not the scientific, but the practical spirit. It
gives birth to religions, but not to philosophies. Of course it is a
mistake to imagine that philosophy and religion are totally separate
and have no community. They are in fact fundamentally akin. But they
are also distinct. Perhaps the truest view is that they are identical
in substance, but different in form. The substance of both is the
absolute reality and the relation of all things, including men, to
that reality. But whereas philosophy presents this subject-matter
scientifically, in {15} the form of pure thought, religion gives it in
the form of sensuous pictures, myths, images, and symbols.
And this gives us the second reason why Indian thought is more
properly classed as religious than philosophical. It seldom or never
rises from sensuous to pure thought. It is poetical rather than
scientific. It is content with symbols and metaphors in place of
rational explanations, and all this is a mark of the religious, rather
than the philosophical, presentation of the truth. For example, the
main thought of the Upanishads is that the entire universe is derived
from a single, changeless, eternal, infinite, being, called Brahman or
Paramatman. When we come to the crucial question how the universe
arises out of this being, we find such passages as this:--"As the
colours in the flame or the red-hot iron proceed therefrom a
thousand-fold, so do all beings proceed from the Unchangeable, and
return again to it." Or again, "As the web issues from the spider, as
little sparks proceed from fire, so from the one soul proceed all
living animals, all worlds, all the gods and all beings." There are
thousands of such passages in the Upanishads. But obviously these
neither explain nor attempt to explain anything. They are nothing but
hollow metaphors. They are poetic rather than scientific. They may
satisfy the imagination and the religious feelings, but not the
rational understanding. Or when again Krishna, in the Bhagavat-Gita,
describes himself as the moon among the lunar mansions, the sun among
the stars, Meru among the high-peaked mountains, it is clear that we
are merely piling sensuous image upon sensuous image without any
further understanding of what the nature of the absolute being in its
own self is. {16} The moon, the sun, Meru, are physical sense-objects.
And this is totally sensuous thinking, whereas the aim of philosophy
is to rise to pure thought. In such passages we are still on the level
of symbolism, and philosophy only begins when symbolism has been
surpassed. No doubt it is possible to take the line that man's thought
is not capable of grasping the infinite as it is in itself, and can
only fall back upon symbols. But that is another question, and at any
rate, whether it is or is not possible to rise from sensuous to pure
thought, philosophy is essentially the attempt to do so.
Lastly, Indian thought is usually excluded from the history of
philosophy because, whatever its character, it lies outside the main
stream of human development. It has been cut off by geographical and
other barriers. Consequently, whatever its value in itself, it has
exerted little influence upon philosophy in general.
The claim is sometimes put forward by Orientals themselves that Greek
philosophy came from India, and if this were true, it would greatly
affect the statement made in the last paragraph. But it is not true.
It used to be believed that Greek philosophy came from "the East," but
this meant Egypt. And even this theory is now abandoned. Greek
culture, especially mathematics and astronomy, owed much to Egypt. But
Greece did not owe its philosophy to that source. The view that it did
was propagated by Alexandrian priests and others, whose sole motive
was, that to represent the triumphs of Greek philosophy as borrowed
from Egypt, flattered their national vanity. It was a great thing,
wherever they found anything good, to say, "this must have come from
us." A precisely similar motive lies behind the {17} Oriental claim
that Greek philosophy came from India. There is not a scrap of
evidence for it, and it rests entirely upon the supposed resemblance
between the two. But this resemblance is in fact mythical. The whole
character of Greek philosophy is European and unoriental to the
back-bone. The doctrine of re-incarnation is usually appealed to. This
characteristically Indian doctrine was held by the Pythagoreans, from
whom it passed to Empedocles and Plato. The Pythagoreans got it from
the Orphic sect, to whom quite possibly it came indirectly from India,
although even this is by no means certain, and is in fact highly
doubtful. But even if this be true, it proves nothing. Re-incarnation
is of little importance in Greek philosophy. Even in Plato, who makes
much of it, it is quite unessential to the fundamental ideas of his
philosophy, and is only artificially connected with them. And the
influence of this doctrine upon Plato's philosophy was thoroughly bad.
It was largely responsible for leading him into the main error of his
philosophy, which it required an Aristotle to correct. All this will
be evident when we come to consider the systems of Plato and
Aristotle.
The origin of Greek philosophy is not to be found in India, or Egypt,
or in any country outside Greece. The Greeks themselves were solely
responsible for it. It is not as if history traces back their thought
only to a point at which it was already highly developed, and cannot
explain its beginnings. We know its history from the time, so to
speak, when it was in the cradle. In the next two chapters we shall
see that the first Greek attempts at philosophising were so much the
beginnings of a beginner, were so very crude and unformed, that it is
{18} mere perversity to suppose that they could not make these simple
efforts for themselves. From those crude beginnings we can trace the
whole development in detail up to its culmination in Aristotle, and
beyond. So there is no need to assume foreign influence at any point.
Greek philosophy begins in the sixth century before Christ. It begins
when men for the first time attempted to give a scientific reply to
the question, "what is the explanation of the world?" Before this era
we have, of course, the mythologies, cosmogonies, and theologies of
the poets. But they contain no attempt at a naturalistic explanation
of things. They belong to the spheres of poetry and religion, not to
philosophy.
It must not be supposed, when we speak of the philosophy of Greece,
that we refer only to the mainland of what is now called Greece. Very
early in history, Greeks of the mainland migrated to the islands of
the Aegean, to Sicily, to the South of Italy, to the coast of Asia
Minor, and elsewhere, and founded flourishing colonies. The Greece of
philosophy includes all these places. It is to be thought of rather
racially than territorially. It is the philosophy of the men of Greek
race, wherever they happened to be situated. And in fact the first
period of Greek philosophy deals exclusively with the thoughts of
these colonial Greeks. It was not till just before the time of
Socrates that philosophy was transplanted to the mainland.
Greek philosophy falls naturally into three periods. The first may be
roughly described as pre-Socratic philosophy, though it does not
include the Sophists who were both the contemporaries and the
predecessors of Socrates. This period is the rise of Greek philosophy.
{19} Secondly, the period from the Sophists to Aristotle, which
includes Socrates and Plato, is the maturity of Greek philosophy, the
actual zenith and culmination of which is undoubtedly the system of
Aristotle. Lastly, the period of post-Aristotelian philosophy
constitutes the decline and fall of the national thought. These are
not merely arbitrary divisions. Each period has its own special
characters, which will be described in the sequel.
A few words must be said of the sources of our knowledge of
pre-Socratic philosophy. If we want to know what Plato and Aristotle
thought about any matter, we have only to consult their works. But the
works of the earlier philosophers have not come down to us, except in
fragments, and several of them never committed their opinions to
writing. Our knowledge of their doctrines is the result of the
laborious sifting by scholars of such materials as are available.
Luckily the material has been plentiful. It may be divided into three
classes. First come the fragments of the original writings of the
philosophers themselves. These are in many cases long and important,
in other cases scanty. Secondly, there are the references in Plato and
Aristotle. Of these by far the most important are to be found in the
first book of Aristotle's "Metaphysics," which is a history of
philosophy up to his own time, and is the first attempt on record to
write a history of philosophy. Thirdly, there is an enormous mass of
references, some valuable, some worthless, contained in the works of
later, but still ancient, writers.
{20}
CHAPTER II
THE IONICS.
The earliest Greek philosophers belong to what in after times came to
be called the Ionic school. The name was derived from the fact that
the three chief representatives of this school, Thales, Anaximander,
and Anaximenes, were all men of Ionia, that is to say, the coast of
Asia Minor.
Thales
As the founder of the earliest school in history, Thales of Miletus is
generally accounted the founder and father of all philosophy. He was
born about 624 B.C. and died about 550 B.C. These dates are
approximate, and it should be understood that the same thing is true
of nearly all the dates of the early philosophers. Different scholars
vary, sometimes as much as ten years, in the dates they give. We shall
not enter into these questions at all, because they are of no
importance. And throughout these lectures it should be understood that
the dates given are approximate.
Thales, at any rate, was a contemporary of Solon and Croesus. He was
famous in antiquity for his mathematical and astronomical learning,
and also for his practical sagacity and wisdom. He is included in {21}
all the accounts of the Seven Sages. The story of the Seven Sages is
unhistorical, but the fact that the lists of their names differ
considerably as given by different writers, whereas the name of Thales
appears in all, shows with what veneration he was anciently regarded.
An eclipse of the sun occurred in 585 B.C., and Thales is alleged to
have predicted it, which was a feat for the astronomy of those times.
And he must have been a great engineer, for he caused a diversion of
the river Halys, when Croesus and his army were unable to cross it.
Nothing else is known of his life, though there were many apocryphal
stories.
No writings by Thales were extant even in the time of Aristotle, and
it is believed that he wrote nothing. His philosophy, if we can call
it by that name, consisted, so far as we know, of two propositions.
Firstly, that the principle of all things is water, that all comes
from water, and to water all returns. And secondly, that the earth is
a flat disc which floats upon water. The first, which is the chief
proposition, means that water is the one primal kind of existence and
that everything else in the universe is merely a modification of
water. Two questions will naturally occur to us. Why did Thales choose
water as the first principle? And by what process does water, in his
opinion, come to be changed into other things; how was the universe
formed out of water? We cannot answer either of these questions with
certainty. Aristotle says that Thales "probably derived his opinion
from observing that the nutriment of all things is moist, and that
even actual heat is generated therefrom, and that animal life is
sustained by water, ... and from the fact that the seeds of all things
possess {22} a moist nature, and that water is a first principle of
all things that are humid." This is very likely the true explanation.
But it will be noted that even Aristotle uses the word "probably," and
so gives his statement merely as a conjecture. How, in the opinion of
Thales, the universe arose out of water, is even more uncertain. Most
likely he never asked himself the question, and gave no explanation.
At any rate nothing is known on the point.
This being the sum and substance of the teaching of Thales, we may
naturally ask why, on account of such a crude and undeveloped idea, he
should be given the title of the father of philosophy. Why should
philosophy be said to begin here in particular? Now, the significance
of Thales is not that his water-philosophy has any value in itself,
but that this was the first recorded attempt to explain the universe
on naturalistic and scientific principles, without the aid of myths
and anthropomorphic gods. Moreover, Thales propounded the problem, and
determined the direction and character, of all pre-Socratic
philosophy. The fundamental thought of that period was, that under the
multiplicity of the world there must be a single ultimate principle.
The problem of all philosophers from Thales to Anaxagoras was, what is
the nature of that first principle from which all things have issued?
Their systems are all attempts to answer this question, and may be
classified according to their different replies. Thus Thales asserted
that the ultimate reality is water, Anaximander indefinite matter,
Anaximenes air, the Pythagoreans number, the Eleatics Being,
Heracleitus fire, Empedocles the four elements, Democritus atoms, and
so on. The first period is thus {23} essentially cosmological in
character, and it was Thales who determined the character. His
importance is that he was the first to propound the question, not that
he gave any rational reply to it.
We saw in the first chapter, that man is naturally a materialist, and
that philosophy is the movement from sensuous to non-sensuous thought.
As we should expect, then, philosophy begins in materialism. The first
answer to the question, what the ultimate reality is, places the
nature of that reality in a sensuous object, water. The other members
of the Ionic school, Anaximander, and Anaximenes, are also
materialists. And from their time onwards we can trace the gradual
rise of thought, with occasional breaks and relapses, from this
sensualism of the Ionics, through the semi-sensuous idealism of the
Eleatics, to the highest point of pure non-sensuous thought, the
idealism of Plato and Aristotle. It is important to keep in mind,
then, that the history of philosophy is not a mere chaotic hotch-potch
of opinions and theories, succeeding each other without connection or
order. It is a logical and historical evolution, each step in which is
determined by the last, and advances beyond the last towards a
definite goal. The goal, of course, is visible to us, but was not
visible to the early thinkers themselves.
Since man begins by looking outwards upon the external world and not
inwards upon his own self, this fact too determines the character of
the first period of Greek philosophy. It concerns itself solely with
nature, with the external world, and only with man as a part of
nature. It demands an explanation of nature. And this is the same as
saying that it is cosmological. The {24} problems of man, of life, of
human destiny, of ethics, are treated by it scantily, or not at all.
It is not till the time of the Sophists that the Greek spirit turns
inwards upon itself and begins to consider these problems, and with
the emergence of that point of view we have passed from the first to
the second period of Greek philosophy.
Because the Ionic philosophers were all materialists they are also
sometimes called Hylicists, from the Greek _hulé_ which means matter.
Anaximander
The next philosopher of the Ionic school is Anaximander. He was an
exceedingly original and audacious thinker. He was probably born about
611 B.C. and died about 547. He was an inhabitant of Miletus, and is
said to have been a disciple of Thales. It will be seen, thus, that he
was a younger contemporary of Thales. He was born at the time that
Thales was flourishing, and was about a generation younger. He was the
first Greek to write a philosophic treatise, which however has been
unfortunately lost. He was eminent for his astronomical and
geographical knowledge, and in this connection was the first to
construct a map. Details of his life are not known.
Now Thales had made the ultimate principle of the universe, water.
Anaximander agrees with Thales that the ultimate principle of things
is material, but he does not name it water, does not in fact believe
that it is any particular kind of matter. It is rather a formless,
indefinite, and absolutely featureless matter in general. {25} Matter,
as we know it, is always some particular kind of matter. It must be
iron, brass, water, air, or other such. The difference between the
different kinds of matter is qualitative, that is to say, we know that
air is air because it has the qualities of air and differs from iron
because iron has the qualities of iron, and so on. The primeval matter
of Anaximander is just matter not yet sundered into the different
kinds of matter. It is therefore formless and characterless. And as it
is thus indeterminate in quality, so it is illimitable in quantity.
Anaximander believed that this matter stretches out to infinity
through space. The reason he gave for this opinion was, that if there
were a limited amount of matter it would long ago have been used up in
the creation and destruction of the "innumerable worlds." Hence he
called it "the boundless." In regard to these "innumerable worlds,"
the traditional opinion about Anaximander was that he believed these
worlds to succeed each other in time, and that first a world was
created, developed, and was destroyed, then another world arose, was
developed and destroyed, and that this periodic revolution of worlds
went on for ever. Professor Burnet, however, is of opinion that the
"innumerable worlds" of Anaximander were not necessarily successive but
rather simultaneously existing worlds. According to this view there
may be any number of worlds existing at the same time. But, even so,
it is still true that these worlds were not everlasting, but began,
developed and decayed, giving place in due time to other worlds.
How, now, have these various worlds been formed out of the formless,
indefinite, indeterminate matter of {26} Anaximander? On this question
Anaximander is vague and has nothing very definite to put forward.
Indeterminate matter by a vaguely conceived process separates itself
into "the hot" and "the cold." The cold is moist or damp. This cold
and moist matter becomes the earth, in the centre of the universe. The
hot matter collects into a sphere of fire surrounding the earth. The
earth in the centre was originally fluid. The heat of the surrounding
sphere caused the waters of the earth progressively to evaporate
giving rise to the envelope of air which surrounds the earth. For the
early Greeks regarded the air and vapour as the same thing. As this
air or vapour expanded under the action of heat it burst the outside
hot sphere of fire into a series of enormous "wheel-shaped husks,"
resembling cart wheels, which encircle the earth. You may naturally
ask how it is that if these are composed of fire we do not see them
continually glowing. Anaximander's answer was that these wheel-shaped
husks are encrusted with thick, opaque vapour, which conceals the
inner fire from our view. But there are apertures, or pipe-like holes
in the vapour-crust, and through these the fire gleams, causing the
appearance of the sun, stars, and moon. You will note that the moon
was, on this theory, considered to be fiery, and not, as we now know
it to be, a cold surface reflecting the sun's light. There were three
of these "cart wheels"; the first was that of the sun, furthest away
from the earth, nearer to us was that of the moon, and closest of all
was that of the fixed stars. The "wheel-shaped husks" containing the
heavenly bodies are revolved round the earth by means of currents of
air. The earth in the centre was believed by {27} Anaximander to be
not spherical but cylindrical. Men live on the top end of this pillar
or cylinder.
Anaximander also developed a striking theory about the origin and
evolution of living beings. In the beginning the earth was fluid and
in the gradual drying up by evaporation of this fluid, living beings
were produced from the heat and moisture. In the first instance these
beings were of a low order. They gradually evolved into successively
higher and higher organisms by means of adaptation to their
environment. Man was in the first instance a fish living in the water.
The gradual drying up left parts of the earth high and dry, and marine
animals migrated to the land, and their fins by adaptation became
members fitted for movement on land. The resemblance of this primitive
theory to modern theories of evolution is remarkable. It is easy to
exaggerate its importance, but it is at any rate clear that
Anaximander had, by a happy guess, hit upon the central idea of
adaptation of species to their environment.
The teaching of Anaximander exhibits a marked advance beyond the
position of Thales. Thales had taught that the first principle of
things is water. The formless matter of Anaximander is,
philosophically, an advance on this, showing the operation of thought
and abstraction. Secondly, Anaximander had definitely attempted to
apply this idea, and to derive from it the existent world. Thales had
left the question how the primal water developed into a world,
entirely unanswered.
Anaximenes
Like the two previous thinkers Anaximenes was an inhabitant of
Miletus. He was born about 588 B.C. and {28} died about 524. He wrote
a treatise of which a small fragment still remains. He agreed with
Thales and Anaximander that the first principle of the universe is
material. With Thales too, he looked upon it as a particular kind of
matter, not indeterminate matter as taught by Anaximander. Thales had
declared it to be water. Anaximenes named air as first principle. This
air, like the matter of Anaximander, stretches illimitably through
space. Air is constantly in motion and has the power of motion
inherent in it and this motion brought about the development of the
universe from air. As operating process of this development Anaximenes
named the two opposite processes of (1) Rarefaction, (2) Condensation.
Rarefaction is the same thing as heat or growing hot, and condensation
is identified with growing cold. The air by rarefaction becomes fire,
and fire borne aloft upon the air becomes the stars. By the opposite
process of condensation, air first becomes clouds and, by further
degrees of condensation, becomes successively water, earth, and rocks.
The world resolves again in the course of time into the primal air.
Anaximenes, like Anaximander, held the theory of "innumerable worlds,"
and these worlds are, according to the traditional view, successive.
But here again Professor Burnet considers that the innumerable worlds
may have been co-existent as well as successive. Anaximenes considered
the earth to be a flat disc floating upon air.
The origin of the air theory of Anaximenes seems to have been
suggested to him by the fact that air in the form of breath is the
principle of life.
The teaching of Anaximenes seems at first sight to be {29} a falling
off from the position of Anaximander, because he goes back to the
position of Thales in favour of a determinate matter as first
principle. But in one respect at least there is here an advance upon
Anaximander. The latter had been vague as to how formless matter
differentiates itself into the world of objects. Anaximenes names the
definite processes of rarefaction and condensation. If you believe, as
these early physicists did, that every different kind of matter is
ultimately one kind of matter, the problem of the differentiation of
the qualities of the existent elements arises. For example, if this
paper is really composed of air, how do we account for its colour, its
hardness, texture, etc. Either these qualities must be originally in
the primal air, or not. If the qualities existed in it then it was not
really one homogeneous matter like air, but must have been simply a
mixture of different kinds of matter. If not, how do these properties
arise? How can this air which has not in it the qualities of things we
see, develop them? The simplest way of getting out of the difficulty
is to found quality upon quantity, and to explain the former by the
amount or quantity, more or less, of matter existent in the same
volume. This is precisely what is meant by rarefaction and
condensation. Condensation would result in compressing more matter
into the same volume. Rarefaction would give rise to the opposite
process. Great compression of air, a great amount of it in a small
space, might account for the qualities, say, of earth and stones, for
example, their heaviness, hardness, colour, etc.
Hence Anaximenes was to some extent a more logical and definite
thinker than Anaximander, but cannot {30} compare with him in audacity
and originality of thought.
Other Ionic Thinkers
We have now considered the three chief thinkers of the Ionic School.
Others there were, but they added nothing new to the teaching of these
three. They followed either Thales or Anaximenes in stating the first
principle of the world either as water or as air. Hippo, for example,
followed Thales, and for him the world is composed of water, Idaeus
agreed with Anaximenes that it is derived from air. Diogenes of
Apollonia is chiefly remarkable for the fact that he lived at a very
much later date. He was a contemporary of Anaxagoras, and opposed to
the more developed teachings of that philosopher the crude materialism
of the Ionic School. Air was by him considered to be the ground of all
things.
{31}
CHAPTER III
THE PYTHAGOREANS
Not much is known of the life of Pythagoras. Three so-called
biographies have come down to us from antiquity, but they were written
hundreds of years after the event, and are filled with a tissue of
extravagant fancies, and with stories of miracles and wonders worked
by Pythagoras. All sorts of fantastic legends seem to have gathered
very early around his life, obscuring from us the actual historical
details. A few definite facts, however, are known. He was born
somewhere between 580 and 570 B.C. at Samos, and about middle age he
migrated to Crotona in South Italy. According to legend, before he
arrived in South Italy he had travelled extensively in Egypt and other
countries of the East. There is, however, no historical evidence of
this. There is nothing in itself improbable in the belief that
Pythagoras made these travels, but it cannot be accepted as proved for
lack of evidence. The legend is really founded simply upon the
oriental flavour of his doctrines. In middle age he arrived in South
Italy and settled at Crotona. There he founded the Pythagorean Society
and lived for many years at the head of it. His later life, the date
and manner of his death, are not certainly known.
Now it is important to note that the Pythagorean {32} Society was not
primarily a school of philosophy at all. It was really a religious and
moral Order, a Society of religious reformers. The Pythagoreans were
closely associated with the Orphic Sect, and took from it the belief
in the transmigration of souls, including transmigration of human
souls into animals. They also taught the doctrine of the "wheel of
things," and the necessity of obtaining "release" from it, by which
one could escape from the weary round of reincarnate lives. Thus they
shared with the Orphic religious Sect the principle of reincarnation.
The Orphic Sect believed that "release" from the wheel of life was to
be obtained by religious ceremonial and ritual. The Pythagoreans had a
similar ritual, but they added to this the belief that intellectual
pursuits, the cultivation of science and philosophy, and, in general,
the intellectual contemplation of the ultimate things of the universe
would be of great help towards the "release" of the soul. From this
arose the tendency to develop science and philosophy. Gradually their
philosophy attained a semi-independence from their religious rites
which justifies us in regarding it definitely as philosophy.
The Pythagorean ethical views were rigorous and ascetic in character.
They insisted upon the utmost purity of life in the members of the
Order. Abstinence from flesh was insisted upon, although this was
apparently a late development. We know that Pythagoras himself was not
a total abstainer from flesh. They forbade the eating of beans. They
wore a garb peculiar to themselves. The body, they taught, is the
prison or tomb of the soul. They thought that one must not attempt to
obtain "release" by suicide, because "man is the {33} property of
God," the chattel of God. They were not politicians in the modern
sense, but their procedure in practice amounted to the greatest
possible interference in politics. It appears that the Pythagoreans
attempted to impose their ordinances upon the ordinary citizens of
Crotona. They aimed at the supersession of the State by their own
Order and they did actually capture the government of Crotona for a
short period. This led to attacks on the Order, and the persecution of
its members. When the plain citizen of Crotona was told not to eat
beans, and that under no circumstances could he eat his own dog, this
was too much. A general persecution occurred. The meeting place of the
Pythagoreans was burnt to the ground, the Society was scattered, and
its members killed or driven away. This occurred between the years 440
and 430 B.C. Some years later the Society revived and continued its
activities, but we do not hear much of it after the fourth century
B.C.
It was largely a mystical society. The Pythagoreans developed their
own ritual, ceremonial and mysteries. This love of mystery, and their
general character as miracle-mongers, largely account for the legends
which grew up around the life of Pythagoras himself. Their scientific
activities were also considerable. They enforced moral self-control.
They cultivated the arts and crafts, gymnastics, music, medicine, and
mathematics. The development of mathematics in early Greece was
largely the work of the Pythagoreans. Pythagoras is said to have
discovered the 47th Proposition of Euclid, and to have sacrificed an
ox in honour thereof. And there is good reason to believe that
practically the whole of the substance of the First Book of Euclid is
the work of Pythagoras.
{34}
Turning now to their philosophical teaching, the first thing that we
have to understand is that we cannot speak of the philosophy of
Pythagoras, but only of the philosophy of the Pythagoreans. For it is
not known what share Pythagoras had in this philosophy or what share
was contributed by his successors. Now we recognize objects in the
universe by means of their qualities. But the majority of these
qualities are not universal in their scope; some things possess some
qualities; others possess others. A leaf, for example, is green, but
not all things are green. Some things have no colour at all. The same
is true of tastes and smells. Some things are sweet; some bitter. But
there is one quality in things which is absolutely universal in its
scope, which applies to everything in the universe--corporeal or
incorporeal. All things are _numerable_, and can be counted. Moreover,
it is impossible to conceive a universe in which number is not to be
found. You could easily imagine a universe in which there is no
colour, or no sweet taste, or a universe in which nothing possesses
weight. But you cannot imagine a universe in which there is no number.
This is an inconceivable thought. Upon these grounds we should be
justified in concluding that number is an extremely important aspect
of things, and forms a fundamental pad of the framework of the world.
And it is upon this aspect of things that the Pythagoreans laid
emphasis.
They drew attention to proportion, order, and harmony as the dominant
notes of the universe. Now when we examine the ideas of proportion,
order, and harmony, we shall see that they are closely connected with
number. Proportion, for example, must necessarily {35} be expressible
by the relation of one number to another. Similarly order is
measurable by numbers. When we say that the ranks of a regiment
exhibit order, we mean that they are arranged in such a way that the
soldiers stand at certain regular distances from each other, and these
distances are measurable by numbers of feet or inches. Lastly,
consider the idea of harmony. If, in modern times, we were to say that
the universe is a harmonious whole, we should understand that we are
merely using a metaphor from music. But the Pythagoreans lived in an
age when men were not practised in thought, and they confused cosmical
harmony with musical harmony. They thought that the two things were
the same. Now musical harmony is founded upon numbers, and the
Pythagoreans were the first to discover this. The difference of notes
is due to the different numbers of vibrations of the sounding
instrument. The musical intervals are likewise based upon numerical
proportions. So that since, for the Pythagoreans, the universe is a
musical harmony, it follows that the essential character of the
universe is number. The study of mathematics confirmed the
Pythagoreans in this idea. Arithmetic is the science of numbers, and
all other mathematical sciences are ultimately reducible to numbers.
For instance, in geometry, angles are measured by the number of
degrees.
Now, as already pointed out, considering all these facts, we might
well be justified in concluding that number is a very important aspect
of the universe, and is fundamental in it. But the Pythagoreans went
much further than this. They drew what seems to us the extraordinary
conclusion that the world is _made of_ {36} numbers. At this point,
then, we reach the heart of the Pythagorean philosophy. Just as Thales
had said that the ultimate reality, the first principle of which
things are composed, is water, so now the Pythagoreans teach that the
first principle of things is number. Number is the world-ground, the
stuff out of which the universe is made.
In the detailed application of this principle to the world of things
we have a conglomeration of extraordinary fancies and extravagances.
In the first place, all numbers arise out of the unit. This is the
prime number, every other number being simply so many units. The unit
then is the first in the order of things in the universe. Again,
numbers are divided into odd and even. The universe, said the
Pythagoreans, is composed of pairs of opposites and contradictories,
and the fundamental character of these opposites is that they are
composed of the odd and even. The odd and even, moreover, they
identified with the limited and the unlimited respectively. How this
identification was made seems somewhat doubtful. But it is clearly
connected with the theory of bipartition. An even number can be
divided by two and therefore it does not set a limit to bipartition.
Hence it is unlimited. An odd number cannot be divided by two, and
therefore it sets a limit to bipartition. The limited and the
unlimited become therefore the ultimate principles of the universe.
The Limit is identified with the unit, and this again with the central
fire of the universe. The Limit is first formed and proceeds to draw
more and more of the unlimited towards itself, and to limit it.
Becoming limited, it becomes a definite "something," a thing. So the
formation of the {37} world of things proceeds. The Pythagoreans drew
up a list of ten opposites of which the universe is composed. They are
(1) Limited and unlimited, (2) odd and even, (3) one and many, (4)
right and left, (5) masculine and feminine, (6) rest and motion, (7)
straight and crooked, (8) light and darkness, (9) good and evil, (10)
square and oblong.
With the further development of the number-theory Pythagoreanism
becomes entirely arbitrary and without principle. We hear, for
example, that 1 is the point, 2 is the line, 3 is the plane, 4 is the
solid, 5 physical qualities, 6 animation, 7 intelligence, health,
love, wisdom. There is no principle in all this. Identification of the
different numbers with different things can only be left to the whim
and fancy of the individual. The Pythagoreans disagreed among
themselves as to what number is to be assigned to what thing. For
example, justice, they said, is that which returns equal for equal. If
I do a man an injury, justice ordains that injury should be done to
me, thus giving equal for equal. Justice must, therefore, be a number
which returns equal for equal. Now the only numbers which do this are
square numbers. Four equals two into two, and so returns equal for
equal. Four, then, must be justice. But nine is equally the square of
three. Hence other Pythagoreans identified justice with nine.
According to Philolaus, one of the most prominent Pythagoreans, the
quality of matter depends upon the number of sides of its smallest
particles. Of the five regular solids, three were known to the
Pythagoreans. That matter whose smallest particles are regular
tetrahedra, said Philolaus, is fire. Similarly earth is composed {38}
of cubes, and the universe is identified with the dodecahedron. This
idea was developed further by Plato in the "Timaeus," where we find
all the five regular solids brought into the theory.
The central fire, already mentioned as identified with the unit, is a
characteristic doctrine of the Pythagoreans. Up to this time it had
been believed that the earth is the centre of the universe, and that
everything revolves round it. But with the Pythagoreans the earth
revolves round the central fire. One feels inclined at once to
identify this with the sun. But this is not correct. The sun, like the
earth, revolves round the central fire. We do not see the central fire
because that side of the earth on which we live is perpetually turned
away from it. This involves the theory that the earth revolves round
the central fire in the same period that it takes to rotate upon its
axis. The Pythagoreans were the first to see that the earth is itself
one of the planets, and to shake themselves free from the geocentric
hypothesis. Round the central fire, sometimes mystically called "the
Hearth of the Universe," revolve ten bodies. First is the
"counter-earth," a non-existent body invented by the Pythagoreans,
next comes the earth, then the sun, the moon, the five planets, and
lastly the heaven of the fixed stars. This curious system might have
borne fruit in astronomy. That it did not do so was largely due to the
influence of Aristotle, who discountenanced the theory, and insisted
that the earth is the centre of the universe. But in the end the
Pythagorean view won the day. We know that Copernicus derived the
suggestion of his heliocentric hypothesis from the Pythagoreans.
{39}
The Pythagoreans also taught "The Great Year," probably a period of
10,000 years, in which the world comes into being and passes away,
going in each such period through the same evolution down to the
smallest details.
There is little to be said by way of criticism of the Pythagorean
system. It is entirely crude philosophy. The application of the number
theory issues in a barren and futile arithmetical mysticism. Hegel's
words in this connection are instructive:--
"We may certainly," he says, "feel ourselves prompted to associate the
most general characteristics of thought with the first numbers: saying
one is the simple and immediate, two is difference and mediation, and
three the unity of both these. Such associations however are purely
external; there is nothing in the mere numbers to make them express
these definite thoughts. With every step in this method, the more
arbitrary grows the association of definite numbers with definite
thoughts ... To attach, as do some secret societies of modern times,
importance to all sorts of numbers and figures is, to some extent an
innocent amusement, but it is also a sign of deficiency of
intellectual resource. These numbers, it is said, conceal a profound
meaning, and suggest a deal to think about. But the point in
philosophy is not what you may think but what you do think; and the
genuine air of thought is to be sought in thought itself and not in
arbitrarily selected symbols." [Footnote 3]

edition, page 198.]

CHAPTER IV
THE ELEATICS
The Eleatics are so called because the seat of their school was at
Elea, a town in South Italy, and Parmenides and Zeno, the two chief
representatives of the school, were both citizens of Elea. So far we
have been dealing with crude systems of thought in which only the
germs of philosophic thinking can be dimly discerned. Now, however,
with the Eleatics we step out definitely for the first time upon the
platform of philosophy. Eleaticism is the first true philosophy. In it
there emerges the first factor of the truth, however poor, meagre, and
inadequate. For philosophy is not, as many persons suppose, simply a
collection of freak speculations, which we may study in historical
order, but at the end of which, God alone knows which we ought to
believe. On the contrary, the history of philosophy presents a
definite line of evolution. The truth unfolds itself gradually in
time.
Xenophanes
The reputed founder of the Eleatic School was Xenophanes. It is,
however, doubtful whether Xenophanes ever went to Elea. Moreover, he
belongs more properly {41} to the history of religion than to the
history of philosophy. The real creator of the Eleatic School was
Parmenides. But Parmenides seized upon certain germs of thought latent
in Xenophanes and transmuted them into philosophic principles. We
have, therefore, in the first instance, to say something of
Xenophanes. He was born about the year 576 B.C., at Colophon in Ionia.
His long life was spent in wandering up and down the cities of Hellas,
as a poet and minstrel, singing songs at banquets and festivals.
Whether, as sometimes stated; he finally settled at Elea is a matter
of doubt, but we know definitely that at the advanced age of
ninety-two he was still wandering about Greece. His philosophy, such
as it is, is expressed in poems. He did not, however, write
philosophical poems, but rather elegies and satires upon various
subjects, only incidentally expressing his religious views therein.
Fragments of these poems have come down to us.
Xenophanes is the originator of the quarrel between philosophy and
religion. He attacked the popular religious notions of the Greeks with
a view to founding a purer and nobler conception of Deity. Popular
Greek religion consisted of a belief in a number of gods who were
conceived very much as in the form of human beings. Xenophanes attacks
this conception of God as possessing human form. It is absurd, he
says, to suppose that the gods wander about from place to place, as
represented in the Greek legends. It is absurd to suppose that the
gods had a beginning. It is disgraceful to impute to them stories of
fraud, adultery, theft and deceit. And Xenophanes inveighs against
Homer and Hesiod for disseminating these degrading conceptions {42} of
the Deity. He argues, too, against the polytheistic notion of a
plurality of gods. That which is divine can only be one. There can
only be one best. Therefore, God is to be conceived as one. And this
God is comparable to mortals neither in bodily form nor understanding.
He is "all eye, all ear, all thought." It is he "who, without trouble,
by his thought governs all things." But it would be a mistake to
suppose that Xenophanes thought of this God as a being external to the
world, governing it from the outside, as a general governs his
soldiers. On the contrary, Xenophanes identified God with the world.
The world is God, a sentient being, though without organs of sense.
Looking out into the wide heavens, he said, "The One is God."
[Footnote 4] The thought of Xenophanes is therefore more properly
described as pantheism than as monotheism. God is unchangeable,
immutable, undivided, unmoved, passionless, undisturbed. Xenophanes
appears, thus, rather as a religious reformer than as a philosopher.
Nevertheless, inasmuch as he was the first to enunciate the
proposition "All is one," he takes his place in philosophy. It was
upon this thought that Parmenides built the foundations of the Eleatic
philosophy.
[Footnote 4: Aristotle, _Metaphysics_, Book I. chapter v.]
Certain other opinions of Xenophanes have been preserved. He observed
fossils, and found shells inland, and the forms of fish and sea-weed
embedded in the rocks in the quarries of Syracuse and elsewhere. From
these he concluded that the earth had risen out of the sea and would
again partially sink into it. Then the human race would be destroyed.
But the earth would again rise from the sea and the human race would
again [43] be renewed. He believed that the sun and stars were burning
masses of vapour. The sun, he thought, does not revolve round the
earth. It goes on in a straight line, and disappears in the remote
distance in the evening. It is not the same sun which rises the next
morning. Every day a new sun is formed out of the vapours of the sea.
This idea is connected with his general attitude towards the popular
religion. His motive was to show that the sun and stars are not divine
beings, but like other beings, ephemeral. Xenophanes also ridiculed
the Pythagoreans, especially their doctrine of re-incarnation.
Parmenides
Parmenides was born about 514 B.C. at Elea. Not much is known of his
life. He was in his early youth a Pythagorean, but recanted that
philosophy and formulated a philosophy of his own. He was greatly
revered in antiquity both for the depth of his intellect, and the
sublimity and nobility of his character. Plato refers to him always
with reverence. His philosophy is comprised in a philosophic didactic
poem which is divided into two parts. The first part expounds his own
philosophy and is called "the way of truth." The second part describes
the false opinions current in his day and is called "the way of
opinion."
The reflection of Parmenides takes its rise from observation of the
transitoriness and changeableness of things. The world, as we know it,
is a world of change and mutation. All things arise and pass away.
Nothing is permanent, nothing stands. One moment it is, another moment
it is not. It is as true to say of {44} anything, that it is not, as
that it is. The truth of things cannot lie here, for no knowledge of
that which is constantly changing is possible. Hence the thought of
Parmenides becomes the effort to find the eternal amid the shifting,
the abiding and everlasting amid the change and mutation of things.
And there arises in this way the antithesis between Being and
not-being. The absolutely real is Being. Not-being is the unreal.
Not-being is not at all. And this not-being he identifies with
becoming, with the world of shifting and changing things, the world
which is known to us by the senses. The world of sense is unreal,
illusory, a mere appearance. It is not-being. Only Being truly is. As
Thales designated water the one reality, as the Pythagoreans named
number, so now for Parmenides the sole reality, the first principle of
things, is Being, wholly unmixed with not-being, wholly excludent of
all becoming. The character of Being he describes, for the most part,
in a series of negatives. There is in it no change, it is absolutely
unbecome and imperishable. It has neither beginning nor end, neither
arising nor passing away. If Being began, it must have arisen either
from Being or from not-being. But for Being to arise out of Being,
that is not a beginning, and for Being to arise out of not-being is
impossible, since there is then no reason why it should arise later
rather than sooner. Being cannot come out of not-being, nor something
out of nothing. _Ex nihilo nihil fit_. This is the fundamental thought
of Parmenides. Moreover, we cannot say of Being that it was, that it
is, that it will be. There is for it no past, no present, and no
future. It is rather eternally and timelessly present. It is undivided
and indivisible. For anything to be divided {45} it must be divided by
something other than itself. But there is nothing other than Being;
there is no not-being. Therefore there is nothing by which Being can
be divided. Hence it is indivisible. It is unmoved and undisturbed,
for motion and disturbance are forms of becoming, and all becoming is
excluded from Being. It is absolutely self-identical. It does not
arise from anything other than itself. It does not pass into anything
other than itself. It has its whole being in itself. It does not
depend upon anything else for its being and reality. It does not pass
over into otherness; it remains, steadfast, and abiding in itself. Of
positive character Being has nothing. Its sole character is simply its
being. It cannot be said that it is this or that; it cannot be said
that it has this or that quality, that it is here or there, then or
now. It simply _is_. Its only quality is, so to speak, "isness."
But in Parmenides there emerges for the first time a distinction of
fundamental importance in philosophy, the distinction between Sense
and Reason. The world of falsity and appearance, of becoming, of
not-being, this is, says Parmenides, the world which is presented to
us by the senses. True and veritable Being is known to us only by
reason, by thought. The senses therefore, are, for Parmenides, the
sources of all illusion and error. Truth lies only in reason. This is
exceedingly important, because this, _that truth lies in reason and not
in the world of sense_, is the fundamental position of idealism.
The doctrine of Being, just described, occupies the first part of the
poem of Parmenides. The second part is the way of false opinion. But
whether Parmenides is here simply giving an account of the false
philosophies {46} of his day, (and in doing this there does not seem
much point,) or whether he was, with total inconsistency, attempting,
in a cosmological theory of his own, to explain the origin of that
world of appearance and illusion, whose very being he has, in the
first part of the poem, denied--this does not seem to be clear. The
theory here propounded, at any rate, is that the sense-world is
composed of the two opposites, the hot and the cold, or light and
darkness. The more hot there is, the more life, the more reality; the
more cold, the more unreality and death.
What position, now, are we to assign to Parmenides in philosophy? How
are we to characterize his system? Such writers as Hegel, Erdmann, and
Schwegler, have always interpreted his philosophy in an idealistic
sense. Professor Burnet, however, takes the opposite view. To quote
his own words: "Parmenides is not, as some have said, the father of
idealism. On the contrary, all materialism depends upon his view."
[Footnote 5] Now if we cannot say whether Parmenides was a materialist
or an idealist, we cannot be said to understand much about his
philosophy. The question is therefore of cardinal importance. Let us
see, in the first place, upon what grounds the materialistic
interpretation of Parmenides is based. It is based upon a fact which I
have so far not mentioned, leaving it for explanation at this moment.
Parmenides said that Being, which is for him the ultimate reality,
occupies space, is finite, and is spherical or globe-shaped. Now that
which occupies space, and has shape, is matter. The ultimate reality
of things, therefore, is conceived by Parmenides as material, and
this, of course, is the {47} cardinal thesis of materialism. This
interpretation of Parmenides is further emphasized in the disagreement
between himself and Melissus, as to whether Being is finite or
infinite. Melissus was a younger adherent of the Eleatic School, whose
chief interest lies in his views on this question. His philosophical
position in general is the same as that of Parmenides. But on this
point they differed. Parmenides asserted that Being is globe-shaped,
and therefore finite. Now it was an essential part of the doctrine of
Parmenides that empty space is non-existent. Empty space is an
existent non-existence. This is self-contradictory, and for
Parmenides, therefore, empty space is simply not-being. There are, for
example, no interstices, or empty spaces between the particles of
matter. Being is "the full," that is, full space with no mixture of
empty space in it. Now Melissus agreed with Parmenides that there is
no such thing as empty space; and he pointed out, that if Being is
globe-shaped, it must be bounded on the outside by empty space. And as
this is impossible, it cannot be true that Being is globe-shaped, or
finite, but must, on the contrary, extend illimitably through space.
This makes it quite clear that Parmenides, Melissus, and the Eleatics
generally, did regard Being as, in some sense, material.
[Footnote 5: _Early Greek Philosophy_, chap. iv. § 89.]
Now, however, let us turn to the other side of the picture. What
ground is there for regarding Parmenides as an idealist? In the first
place, we may say that his ultimate principle, Being, whatever he may
have thought of it, is not in fact material, but is essentially an
abstract thought, a concept. Being is not here, it is not there. It is
not in any place or time. It is not to be found by the senses. It is
to be found only in reason. {48} We form the idea of Being by the
process of abstraction. For example, we see this desk. Our entire
knowledge of the desk consists in our knowledge of its qualities. It
is square, brown, hard, odourless, etc. Now suppose we successively
strip off these qualities in thought--its colour, its size, its shape.
We shall ultimately be left with nothing at all except its mere being.
We can no longer say of it that it is hard, square, etc. We can only
say "it is." As Parmenides said, Being is not divisible, movable; it
is not here nor there, then nor now. It simply "is." This is the
Eleatic notion of Being, and it is a pure concept. It may be compared
to such an idea as "whiteness." We cannot see "whiteness." We see
white things, but not "whiteness" itself. What, then, is "whiteness"?
It is a concept, that is to say, not a particular thing, but a general
idea, which we form by abstraction, by considering the quality which
all white things have in common, and neglecting the qualities in which
they differ. Just so, if we consider the common character of all
objects in the universe, and neglect their differences, we shall find
that what they all have in common is simply "being." Being then is a
general idea, or concept. It is a thought, and not a thing.
Parmenides, therefore, actually placed the absolute reality of things
in an idea, in a thought, though he may have conceived it in a
material and sensuous way. Now the cardinal thesis of idealism is
precisely this, that the absolute reality, of which the world is a
manifestation, consists in thought, in concepts. Parmenides, on this
view, was an idealist.
Moreover, Parmenides has clearly made the distinction between sense
and reason. True Being is not known to {49} the senses, but only to
reason, and this distinction is an essential feature of all idealism.
Materialism is precisely the view that reality is to be found in the
world of sense. But the proposition of Parmenides is the exact
opposite of this, namely, that reality is to be found only in reason.
Again, there begins to appear for the first time in Parmenides the
distinction between reality and appearance. Parmenides, of course,
would not have used these terms, which have been adopted in modern
times. But the thought which they express is unmistakably there. This
outward world, the world of sense, he proclaims to be illusion and
appearance. Reality is something which lies behind, and is invisible
to the senses. Now the very essence of materialism is that this
material world, this world of sense, is the real world. Idealism is
the doctrine that the sense-world is an appearance. How then can
Parmenides be called a materialist?
How are we to reconcile these two conflicting views of Parmenides? I
think the truth is that these two contradictories lie side by side in
Parmenides unreconciled, and still mutually contradicting each other.
Parmenides himself did not see the contradiction. If we emphasize the
one side, then Parmenides was a materialist. If we emphasize the other
side, then he is to be interpreted as an idealist. In point of fact,
in the history of Greek philosophy, both these sides of Parmenides
were successively emphasized. He became the father both of materialism
and of idealism. His immediate successors, Empedocles and Democritus,
seized upon the materialistic aspect of his thought, and developed it.
The essential thought of Parmenides was that Being cannot arise from
not-being, and that Being neither {50} arises nor passes away. If we
apply this idea to matter we get what in modern times is called the
doctrine of the "indestructibility of matter." Matter has no beginning
and no end. The apparent arising and passing away of things is simply
the aggregation and separation of particles of matter which, in
themselves, are indestructible. This is precisely the position of
Democritus. And his doctrine, therefore, is a materialistic rendering
of the main thought of Parmenides that Being cannot arise from
not-being or pass into not-being.
It was not till the time of Plato that the idealistic aspect of the
Parmenidean doctrine was developed. It was the genius of Plato which
seized upon the germs of idealism in Parmenides and developed them.
Plato was deeply influenced by Parmenides. His main doctrine was that
the reality of the world is to be found in thought, in concepts, in
what is called "the Idea." And he identified the Idea with the Being
of Parmenides.
But still, it may be asked, which is the true view of Parmenides?
Which is the historical Parmenides? Was not Plato in interpreting him
idealistically reading his own thought into Parmenides? Are not we, if
we interpret him as an idealist, reading into him later ideas? In one
sense this is perfectly true. It is clear from what Parmenides himself
said that he regarded the ultimate reality of things as material. It
would be a complete mistake to attribute to him a fully developed and
consistent system of idealism. If you had told Parmenides that he was
an idealist, he would not have understood you. The distinction between
materialism and idealism was not then developed. If you had told him,
moreover, that Being is a concept, he would not have understood {51}
you, because the theory of concepts was not developed until the time
of Socrates and Plato. Now it is the function of historical criticism
to insist upon this, to see that later thought is not attributed to
Parmenides. But if this is the function of historical scholarship, it
is equally the function of philosophic insight to seize upon the germs
of a higher thought amid the confused thinking of Parmenides, to see
what he was groping for, to see clearly what he saw only vaguely and
dimly, to make explicit what in him was merely implicit, to exhibit
the true inwardness of his teaching, to separate what is valuable and
essential in it from what is worthless and accidental. And I say that
in this sense the true and essential meaning of Parmenides is his
idealism. I said in the first chapter that philosophy is the movement
from sensuous to non-sensuous thought. I said that it is only with the
utmost difficulty that this movement occurs. And I said that even the
greatest philosophers have sometimes failed herein. In Parmenides we
have the first example of this. He began by propounding the truth that
Being is the essential reality, and Being, as we saw, is a concept.
But Parmenides was a pioneer. He trod upon unbroken ground. He had not
behind him, as we have, a long line of idealistic thinkers to guide
him. So he could not maintain this first non-sensuous thought. He
could not resist the temptation to frame for himself a mental image, a
picture, of Being. Now all mental images and pictures are framed out
of materials supplied to us by the senses. Hence it comes about that
Parmenides pictured Being as a globe-shaped something occupying space.
But this is not the truth of Parmenides. This is simply his failure to
realise {52} and understand his own principle, and to think his own
thought. It is true that his immediate successors, Empedocles and
Democritus, seized upon this, and built their philosophies upon it.
But in doing so they were building upon the darkness of Parmenides,
upon his dimness of vision, upon his inability to grapple with his own
idea. It was Plato who built upon the light of Parmenides.
Zeno
The third and last important thinker of the Eleatic School is Zeno
who, like Parmenides, was a man of Elea. His birth is placed about 489
B.C. He composed a prose treatise in which he developed his
philosophy. Zeno's contribution to Eleaticism is, in a sense, entirely
negative. He did not add anything positive to the teachings of
Parmenides. He supports Parmenides in the doctrine of Being. But it is
not the conclusions of Zeno that are novel, it is rather the reasons
which he gave for them. In attempting to support the Parmenidean
doctrine from a new point of view he developed certain ideas about the
ultimate character of space and time which have since been of the
utmost importance in philosophy. Parmenides had taught that the world
of sense is illusory and false. The essentials of that world are two--
multiplicity and change. True Being is absolutely one; there is in it
no plurality or multiplicity. Being, moreover, is absolutely static
and unchangeable. There is in it no motion. Multiplicity and motion
are the two characteristics of the false world of sense. Against
multiplicity and motion, therefore, Zeno directed his {53} arguments,
and attempted indirectly to support the conclusions of Parmenides by
showing that multiplicity and motion are impossible. He attempted to
force multiplicity and motion to refute themselves by showing that, if
we assume them as real, contradictory propositions follow from that
assumption. Two propositions which contradict each other cannot both
be true. Therefore the assumptions from which both follow, namely,
multiplicity and motion, cannot be real things.
_Zeno's arguments against multiplicity_.

large. The many must be infinitely small. For it is composed of units.
This is what we mean by saying that it is many. It is many parts or
units. These units must be indivisible. For if they are further
divisible, then they are not units. Since they are indivisible they
can have no magnitude, for that which has magnitude is divisible. The
many, therefore, is composed of units which have no magnitude. But if
none of the parts of the many have magnitude, the many as a whole has
none. Therefore, the many is infinitely small. But the many must also
be infinitely large. For the many has magnitude, and as such, is
divisible into parts. These parts still have magnitude, and are
therefore further divisible. However far we proceed with the division
the parts still have magnitude and are still divisible. Hence the many
is divisible _ad infinitum_. It must therefore be composed of an
infinite number of parts, each having magnitude. But the smallest
magnitude, multiplied by infinity, becomes an infinite magnitude.
Therefore the many is infinitely large. (2) The {54} many must be, in
number, both limited and unlimited. It must be limited because it is
just as many as it is, no more, no less. It is, therefore, a definite
number. But a definite number is a finite or limited number. But the
many must be also unlimited in number. For it is infinitely divisible,
or composed of an infinite number of parts.
_Zeno's arguments against motion_.
(1) In order to travel a distance, a body must first travel half the
distance. There remains half left for it still to travel. It must then
travel half the remaining distance. There is still a remainder. This
progress proceeds infinitely, but there is always a remainder
untravelled. Therefore, it is impossible for a body to travel from one
point to another. It can never arrive. (2) Achilles and the tortoise
run a race. If the tortoise is given a start, Achilles can never catch
it up. For, in the first place, he must run to the point from which
the tortoise started. When he gets there, the tortoise will have gone
to a point further on. Achilles must then run to that point, and finds
then that the tortoise has reached a third point. This will go on for
ever, the distance between them continually diminishing, but never
being wholly wiped out. Achilles will never catch up the tortoise. (3)
This is the story of the flying arrow. An object cannot be in two
places at the same time. Therefore, at any particular moment in its
flight the arrow is in one place and not in two. But to be in one
place is to be at rest. Therefore in each and every moment of its
flight it is at rest. It is thus at rest throughout. Motion is
impossible.
{55}
This type of argument is, in modern times, called "antinomy." An
antinomy is a proof that, since two contradictory propositions equally
follow from a given assumption, that assumption must be false. Zeno is
also called by Aristotle the inventor of dialectic. Dialectic
originally meant simply discussion, but it has come to be a technical
term in philosophy, and is used for that type of reasoning which seeks
to develop the truth by making the false refute and contradict itself.
The conception of dialectic is especially important in Zeno, Plato,
Kant, and Hegel.
All the arguments which Zeno uses against multiplicity and motion are
in reality merely variations of one argument. That argument is as
follows. It applies equally to space, to time, or to anything which
can be quantitatively measured. For simplicity we will consider it
only in its spatial significance. Any quantity of space, say the space
enclosed within a circle, must either be composed of ultimate
indivisible units, or it must be divisible _ad infinitum_. If it is
composed of indivisible units, these must have magnitude, and we are
faced with the contradiction of a magnitude which cannot be divided.
If it is divisible _ad infinitum_, we are faced with the contradiction
of supposing that an infinite number of parts can be added up and make
a finite sum-total. It is thus a great mistake to suppose that Zeno's
stories of Achilles and the tortoise, and of the flying arrow, are
merely childish puzzles. On the contrary, Zeno was the first, by means
of these stories, to bring to light the essential contradictions which
lie in our ideas of space and time, and thus to set an important
problem for all subsequent philosophy.
{56}
All Zeno's arguments are based upon the one argument described above,
which may be called the antinomy of infinite divisibility. For
example, the story of the flying arrow. At any moment of its flight,
says Zeno, it must be in one place, because it cannot be in two places
at the same moment. This depends upon the view of time as being
infinitely divisible. It is only in an infinitesimal moment, an
absolute moment having no duration, that the arrow is at rest. This,
however, is not the only antinomy which we find in our conceptions of
space and time. Every mathematician is acquainted with the
contradictions immanent in our ideas of infinity. For example, the
familiar proposition that parallel straight lines meet at infinity, is
a contradiction. Again, a decreasing geometrical progression can be
added up to infinity, the infinite number of its terms adding up in
the sum-total to a finite number. The idea of infinite space itself is
a contradiction. You can say of it exactly what Zeno said of the many.
There must be in existence as much space as there is, no more. But
this means that there must be a definite and limited amount of space.
Therefore space is finite. On the other hand, it is impossible to
conceive a limit to space. Beyond the limit there must be more space.
Therefore space is infinite. Zeno himself gave expression to this
antinomy in the form of an argument which I have not so far mentioned.
He said that everything which exists is in space. Space itself exists,
therefore space must be in space. That space must be in another space
and so _ad infinitum_. This of course is merely a quaint way of saying
that to conceive a limit to space is impossible.
But to return to the antinomy of infinite divisibility, {57} on which
most of Zeno's arguments rest, you will perhaps expect me to say
something of the different solutions which have been offered. In the
first place, we must not forget Zeno's own solution. He did not
propound this contradiction for its own sake, but to support the
thesis of Parmenides. His solution is that as multiplicity and motion
contain these contradictions, therefore multiplicity and motion cannot
be real. Therefore, there is, as Parmenides said, only one Being, with
no multiplicity in it, and excludent of all motion and becoming. The
solution given by Kant in modern times is essentially similar.
According to Kant, these contradictions are immanent in our
conceptions of space and time, and since time and space involve these
contradictions it follows that they are not real beings, but
appearances, mere phenomena. Space and time do not belong to things as
they are in themselves, but rather to our way of looking at things.
They are forms of our perception. It is our minds which impose space
and time upon objects, and not objects which impose space and time
upon our minds. Further, Kant drew from these contradictions the
conclusion that to comprehend the infinite is beyond the capacity of
human reason. He attempted to show that, wherever we try to think the
infinite, whether the infinitely large or the infinitely small, we
fall into irreconcilable contradictions. Therefore, he concluded that
human faculties are incapable of apprehending infinity. As might be
expected, many thinkers have attempted to solve the problem by denying
one or other side of the contradiction, by saying that one or other
side does not follow from the premises, that one is true and the other
false. David Hume, for example, {58} denied the infinite divisibility
of space and time, and declared that they are composed of indivisible
units having magnitude. But the difficulty that it is impossible to
conceive of units having magnitude which are yet indivisible is not
satisfactorily explained by Hume. And in general, it seems that any
solution which is to be satisfactory must somehow make room for both
sides of the contradiction. It will not do to deny one side or the
other, to say that one is false and the other true. A true solution is
only possible by rising above the level of the two antagonistic
principles and taking them both up to the level of a higher
conception, in which both opposites are reconciled.
This was the procedure followed by Hegel in his solution of the
problem. Unfortunately his solution cannot be fully understood without
some knowledge of his general philosophical principles, on which it
wholly depends. I will, however, try to make it as plain as possible.
In the first place, Hegel did not go out of his way to solve these
antinomies. They appear as mere incidents in the development of his
thought. He did not regard them as isolated cases of contradiction
which occur in thought, as exceptions to a general rule, which
therefore need special explanation. On the contrary, he regarded them,
not as exceptions to, but as examples of, the essential character of
reason. All thought, all reason, for Hegel, contains immanent
contradictions which it first posits and then reconciles in a higher
unity, and this particular contradiction of infinite divisibility is
reconciled in the higher notion of quantity. The notion of quantity
contains two factors, namely the one and the many. Quantity means
precisely a many in {59} one, or a one in many. If, for example, we
consider a quantity of anything, say a heap of wheat, this is, in the
first place, one; it is one whole. Secondly, it is many; for it is
composed of many parts. As one it is continuous; as many it is
discrete. Now the true notion of quantity is not one, apart from many,
nor many apart from one. It is the synthesis of both. It is a many
_in_ one. The antinomy we are considering arises from considering one
side of the truth in a false abstraction from the other. To conceive
unity as not being in itself multiplicity, or multiplicity as not
being unity, is a false abstraction. The thought of the one involves
the thought of the many, and the thought of the many involves the
thought of the one. You cannot have a many without a one, any more
than you can have one end of a stick without the other. Now, if we
consider anything which is quantitatively measured, such as a straight
line, we may consider it, in the first place, as one. In that case it
is a continuous indivisible unit. Next we may regard it as many, in
which case it falls into parts. Now each of these parts may again be
regarded as one, and as such is an indivisible unit; and again each
part may be regarded as many, in which case it falls into further
parts; and this alternating process may go on for ever. This is the
view of the matter which gives rise to the contradictions we have been
considering. But it is a false view. It involves the false abstraction
of first regarding the many as something that has reality apart from
the one, and then regarding the one as something that has reality
apart from the many. If you persist in saying that the line is simply
one and not many, then there arises the theory of indivisible units.
If you {60} persist in saying it is simply many and not one, then it
is divisible _ad infinitum_. But the truth is that it is neither simply
many nor simply one; it is a many in one, that is, it is a _quantity_.
Both sides of the contradiction are, therefore, in one sense true, for
each is a factor of the truth. But both sides are also false, if and
in so far as, each sets itself up as the whole truth.
Critical Remarks on Eleaticism.
The consideration of the meaning of Zeno's doctrine will give us an
insight into the essentials of the position of the Eleatics. Zeno said
that motion and multiplicity are not real. Now what does this mean?
Did Zeno mean to say that when he walked about the streets of Elea, it
was not true that he walked about? Did he mean that it was not a fact
that he moved from place to place? When I move my arms, did he mean
that I am not moving my arms, but that they really remain at rest all
the time? If so, we might justly conclude that this philosophy is a
mere craze of speculation run mad, or else a joke. But this is not
what is meant. The Eleatic position is that though the world of sense,
of which multiplicity and motion are essential features, may exist,
yet that outward world is not the true Being. They do not deny that
the world exists. They do not deny that motion exists or that
multiplicity exists. These things no sane man can deny. The existence
of motion and multiplicity is, as Hegel says, as sensuously certain as
the existence of elephants. Zeno, then, does not deny the existence of
the world. What he denies is the truth of existence. What he means is:
certainly there is motion and multiplicity; certainly the world is
here, is present to our senses, but it is not the true world. It is
{61} not reality. It is mere appearance, illusion, an outward show and
sham, a hollow mask which hides the real being of things. You may ask
what is meant by this distinction between appearance and reality. Is
not even an appearance real? It appears. It exists. Even a delusion
exists, and is therefore a real thing. So is not the distinction
between appearance and reality itself meaningless? Now all this is
perfectly true, but it does not comprehend quite what is meant by the
distinction. What is meant is that the objects around us have
existence, but not self-existence, not self-substantiality. That is to
say, their being is not in themselves, their existence is not grounded
in themselves but is grounded in another, and flows from that other.
They exist, but they are not independent existences. They are rather
beings whose being flows into them from another, which itself is
self-existent and self-substantial. They are, therefore, mere
appearances of that other, which is the reality. Of course the
Eleatics did not speak of appearance and reality in these terms. But
this is what they were groping for, and dimly saw.
If we now look back upon the road on which we have travelled from the
beginning of Greek philosophy, we shall be able to characterize the
direction in which we have been moving. The earliest Greek
philosophers, the Ionics, propounded the question, "what is the
ultimate principle of things?" and answered it by declaring that the
first principle of things is matter. The second Greek School, the
Pythagoreans, answered the same question by declaring numbers to be
the first principle. The third school, the Eleatics, answered the
question by asserting that the first principle of things is Being.
{62} Now the universe, as we know it, is both quantitative and
qualitative. Quantity and quality are characteristics of every
sense-object. These are not, indeed, the only characteristics of the
world, but they are the only characteristics which have so far come to
light. Now the position of the Ionics was that the ultimate reality is
both quantitative and qualitative, that is to say, it is matter, for
matter is just what has both quantity and quality. The Pythagoreans
abstracted from the quality of things. They stripped off the
qualitative aspect from things, and were accordingly left with only
quantity as ultimate reality. Quantity is the same as number. Hence
the Pythagorean position that the world is made of numbers. The
Eleatic philosophy, proceeding one step further in the same direction,
abstracted from quantity as well as quality. Whereas the Pythagoreans
had denied the qualitative aspect of things, leaving themselves only
with the quantitative, the Eleatics denied both quantity and quality,
for in denying multiplicity they denied quantity. Therefore they are
left with the total abstraction of mere Being which has in it neither
dividedness (quantity), nor positive character (quality). The rise
from the Ionic to the Eleatic philosophy is therefore essentially a
rise from sensuous to pure thinking. The Eleatic Being is a pure
abstract thought. The position of the Pythagoreans on the other hand
is that of semi-sensuous thought. They form the stepping-stone from
the Ionics to the Eleatics.
Now let us consider what of worth there is in this Eleatic principle,
and what its defects are. In the first place, it is necessary for us
to understand that the Eleatic philosophy is the first monism. A
monistic philosophy {63} is a philosophy which attempts to explain the
entire universe from one single principle. The opposite of monism is
therefore pluralism, which is that kind of philosophy which seeks to
explain the universe from many ultimate and equally underived
principles. But more particularly and more frequently we speak of the
opposite of monism as being dualism, that is to say, the position that
there are two ultimate principles of explanation. If, for example, we
say that all the good in the universe arises from one source which is
good, and that all the evil arises from another source which is evil,
and that these sources of good and evil cannot be subordinated one to
the other, and that one does not arise out of the other, but both are
co-ordinate and equally primeval and independent, that position would
be a dualism. All philosophy, which is worthy of the name, seeks, in
some sense, a monistic explanation of the universe, and when we find
that a system of philosophy breaks down and fails, then we may nearly
always be sure its defect will reveal itself as an unreconciled
dualism. Such a philosophy will begin with a monistic principle, and
will attempt to derive or deduce the entire universe from it, but
somewhere or other it comes across something in the world which it
cannot bring under that principle. Then it is left with two equally
ultimate existences, neither of which can be derived from the other.
Thus it breaks out into dualism.
Now the search for a monistic explanation of things is a universal
tendency of human thought. Wherever we look in the world of thought,
we find that this monistic tendency appears. I have already said that
it appears throughout the history of philosophy. It reveals itself,
{64} too, very clearly in the history of religion. Religion begins in
polytheism, the belief in many gods. From that it passes on to
monotheism, the belief in one God, who is the sole author and creator
of the universe. In Hindu thought we find the same thing. Hindu
thought is based upon the principle that "All is one." Everything in
the world is derived from one ultimate being, Brahman. But not only is
this monistic tendency traceable in religion and philosophy; it is
also traceable in science. The progress of scientific explanation is
essentially a progress towards monism. In the first place, the
explanation of isolated facts consists always in assigning causes for
them. Suppose there is a strange noise in your room at night. You say
it is explained when you find that it is due to the falling of a book
or the scuttling of a rat across the floor. The noise is thus
explained by assigning a cause for it. But this simply means that you
have robbed it of its isolated and exceptional position, and reduced
it to the position of an example of a general law. When the water
freezes in your jug, you say that the cause of this is the cold. It is
an example of the law that whenever the cold reaches a certain degree,
then, other things being equal, water solidifies. But to assign causes
in this way is not really to explain anything. It does not give any
reason for an event happening. You cannot see any reason why water
should solidify in the cold. It merely tells us that the event is not
exceptional, but is an example of what always happens. It reduces the
isolated event to a case of a general law, which "explains," not
merely this one event, but possibly millions of events. It is not
merely that cold solidifies the water in your jug. {65} It equally
solidifies the water in everybody's jug. The same law "explains" all
these, and likewise "explains" icebergs and the polar caps on the
earth and the planet Mars. In fact scientific explanation means the
reduction of millions of facts to one principle. But science does not
stop here. It seeks further to explain the laws themselves, and its
method is to reduce the many laws to one higher and more general law.
A familiar example of this is the explanation of Kepler's laws of the
planetary motions. Kepler laid down three such laws. The first was
that planets move in elliptical orbits with the sun in one focus. The
second was that planets describe equal areas in equal times. The third
was a rather more complicated law. Kepler knew these laws from
observation, but he could not explain them. They were explained by
Newton's discovery of the law of gravitation. Newton proved that
Kepler's three laws could be mathematically deduced from the law of
gravitation. In that way Kepler's laws were explained, and not only
Kepler's laws, but many other astronomical laws and facts. Thus the
explanation of the many isolated facts consists in their reduction to
the one law, and the explanation of the many laws consists in their
reduction to the one more general law. As knowledge advances, the
phenomena of the universe come to be explained by fewer and fewer, and
wider and wider, general principles. Obviously the ultimate goal would
be the explanation of all things by one principle. I do not mean to
say that scientific men have this end consciously in view. But the
point is that the monistic tendency is there. What is meant by the
explanation is the reduction of all things to one principle.
{66}
In philosophy, in religion, and in science, then, we find this
monistic tendency of thought. But it might be asked how we know that
this universal tendency is right? How do we know that it is not merely
a universal error? Is there no logical or philosophical basis for the
belief that the ultimate explanation of things must be one? Now this
is a subject which takes us far afield from Greek philosophy. The
philosophical basis of monism was never thought out till the time of
Spinoza. So we cannot go into it at length here. But, quite shortly,
the question is--Is there any reason for believing that the ultimate
explanation of things must be one? Now if we are to explain the
universe, two conditions must be fulfilled. In the first place, the
ultimate reality by which we attempt to explain everything must
explain all the other things in the world. It must be possible to
deduce the whole world from it. Secondly, the first principle must
explain itself. It cannot be a principle which itself still requires
explanation by something else. If it is itself not self-explanatory,
but is an ultimate mystery, then even if we succeed in deducing the
universe from it, nothing is thereby explained. This, for example, is
precisely the defect of materialism. Even if we suppose it proved that
all things, including mind, arise from matter, yet the objection
remains that this explains nothing at all, for matter is not a
self-explanatory existence. It is an unintelligible mystery. And to
reduce the universe to an ultimate mystery is not to explain it.
Again; some people think that the world is to be explained by what
they call a "first cause." But why should any cause be the first? Why
should we stop anywhere in the chain of causes? Every cause is {67}
necessarily the effect of a prior cause. The child, who is told that
God made the world, and who inquires who, in that case, made God, is
asking a highly sensible question. Or suppose, in tracing back the
chain of causes, we come upon one which we have reason to say is
really the first, is anything explained thereby? Still we are left
with an ultimate mystery. Whatever the principle of explanation is, it
cannot be a principle of this kind. It must be a principle which
explains itself, and does not lead to something further, such as
another cause. In other words, it must be a principle which has its
whole being in itself, which does not for its completeness refer us to
anything beyond itself. It must be something fully comprehended in
itself, without reference to anything outside it. That is to say, it
must be what we call self-determined or absolute. Now any absolute
principle must necessarily be one. Suppose that it were two. Suppose
you attempt to explain the world by two principles, X and Y, each of
which is ultimate, neither being derived from the other. Then what
relation does X bear to Y? We cannot fully comprehend X without
knowing its relation to Y. Part of the character and being of X is
constituted by its relation to Y. Part of X's character has to be
explained by Y. But that is not to be self-explained. It is to be
explained by something not itself. Therefore, the ultimate explanation
of things must be one.
The Eleatics, then, were perfectly correct in saying that all is one,
and that the ultimate principle of the universe, Being, is one. But if
we examine the way in which they carried out their monism, we shall
see that it broke down in a hopeless dualism. How did they {68}
explain the existence of the world? They propounded the principle of
Being, as the ultimate reality. How then did they derive the actual
world from that principle? The answer is that they neither derived it
nor made any attempt to derive it. Instead of deducing the world from
their first principle, they simply denied the reality of the world
altogether. They attempted to solve the problem by denying the
existence of the problem. The world, they said, is simply not-being.
It is an illusion. Now certainly it is a great thing to know which is
the true world, and which the false, but after all this is not an
explanation. To call the world an illusion is not to explain it. If
the world is reality, then the problem of philosophy is, how does that
reality arise? If the world is illusion, then the problem is, how does
that illusion arise? Call it illusion, if you like. But this is not
explaining it. It is simply calling it names. This is the defect, too,
of Indian philosophy in which the world is said to be Maya--delusion.
Hence in the Eleatic philosophy there are two worlds brought face to
face, lying side by side of each other, unreconciled--the world of
Being, which is the true world, and the world of facts, which is
illusion. Although the Eleatics deny the sense-world, and call it
illusion, yet of this illusion they cannot rid themselves. In some
sense or other, this world is here, is present. It comes back upon our
senses, and demands explanation. Call it illusion, but it still stands
beside the true world, and demands that it be deduced from that. So
that the Eleatics have two principles, the false world and the true
world, simply lying side by side, without any connecting link between
them, without anything to {69} show how the one arises from the other.
It is an utterly irreconcilable dualism.
It is easy to see why the Eleatic philosophy broke down in this
dualism. It is due to the barrenness of their first principle itself.
Being, they say, has in it no becoming. All principle of motion is
expressly excluded from it. Likewise they deny to it any multiplicity.
It is simply one, without any many in it. If you expressly exclude
multiplicity and becoming from your first principle, then you can
never get multiplicity and becoming out of it. You cannot get out of
it anything that is not in it. If you say absolutely there is no
multiplicity in the Absolute, then it is impossible to explain how
multiplicity comes into this world. It is exactly the same in regard
to the question of quality. Pure Being is without quality. It is mere
"isness." It is an utterly featureless, characterless Being, perfectly
empty and abstract. How then can the quality of things issue from it?
How can all the riches and variety of the world come out of this
emptiness? The Eleatics are like jugglers who try to make you believe
that they get rabbits, guinea-pigs, pieces of string, paper, and
ribbon, out of an entirely empty top-hat. One can see how utterly
barren and empty this principle is, if one translates it into
figurative language, that is to say, into the language of religion.
The Eleatic principle would correspond to a religion in which we said
that "God is," but beyond the fact that He "is," He has absolutely no
character. But surely this is a wholly barren and meagre conception of
the Deity. In the Christian religion we are accustomed to hear such
expressions as, not only that "God is," but that "God is Love," "God
is Power," {70} "God is Goodness," "God is Wisdom." Now objection may
certainly be taken to these predicates and epithets on the ground that
they are merely figurative and anthropomorphic. In fact, they exhibit
the tendency to think non-sensuous objects sensuously. These
predicates are merely picked up from the finite world and applied
haphazard to God, for whom they are entirely inadequate. But at least
these expressions teach us, that out of mere emptiness nothing can
come; that the world cannot arise out of something which is lower and
poorer than itself. Here in the world we find in a certain measure,
love, wisdom, excellence, power. These things cannot spring from a
source which is so poor that it contains nothing but "isness." The
less can arise out of the greater, but not the greater out of the
less. We may contrast Eleaticism not only with Christianity, but even
with popular modern agnosticism. According to this, the Absolute is
unknowable. But what the agnostic means is that human reason is
inadequate to grasp the greatness of the ultimate being. But the
Eleatic principle is, not that in saying "God is Love, Power, Wisdom,"
we are saying too little about God, and that our ideas are inadequate
to express the fullness of His being, but on the contrary, that they
express too high an idea for God, of whom nothing can be said except
"He is," because there is absolutely nothing more to say. This
conception of God is the conception of an absolutely empty being.
Monism, I said, is a necessary idea in philosophy. The Absolute must
be one. But an utterly abstract monism is impossible. If the Absolute
is simply one, wholly excludent of all process and multiplicity, out
of such an abstraction the process and multiplicity of the {71} world
cannot issue. The Absolute is not simply one, or simply many. It must
be a many in one, as correctly set forth in the Christian doctrine of
the Trinity. Religion moves from an abstract polytheism (God is many)
to an abstract monotheism (God is one; Judaism, Hinduism and Islam).
But it does not stop there. It rightly passes on to a concrete
monotheism (God is many in one; Christianity). There are two popular
misconceptions regarding the doctrine of the Trinity. The first
mistake is that of popular rationalism, the second is that of popular
theology. Popular rationalism asserts that the doctrine of the Trinity
is contrary to reason. Popular theology asserts that it is a mystery
which transcends reason. But the truth is that it neither contradicts
nor transcends reason. On the contrary, it is in itself the highest
manifestation of reason. What is really a mystery, what really
contradicts reason, is to suppose that God, the Absolute, is simply
one without any multiplicity. This contradiction results in the fatal
dualism which broke out in Eleaticism, and has broken out in every
other system of thought, such as that of the Hindus or that of
Spinoza, which begins with the conception of the Absolute as a pure
one, totally exclusive of the many.

CHAPTER V
HERACLEITUS
Heracleitus was born about 535 B.C., and is believed to have lived to
the age of sixty. This places his death at 475 B.C. He was thus
subsequent to Xenophanes, contemporary with Parmenides, and older than
Zeno. In historical order of time, therefore, he runs parallel to the
Eleatics. Heracleitus was a man of Ephesus in Asia Minor. He was an
aristocrat, descendant of a noble Ephesian family, and occupied in
Ephesus the nominal position of basileus, or King. This, however,
merely meant that he was the Chief Priest of the local branch of the
Eleusinian mysteries, and this position he resigned in favour of his
brother. He appears to have been a man of a somewhat aloof, solitary,
and scornful nature. He looked down, not only upon the common herd,
but even upon the great men of his own race. He mentions Xenophanes
and Pythagoras in terms of obloquy. Homer, he thinks, should be taken
out and whipped. Hesiod he considers to be the teacher of the common
herd, one with them, "a man," he says, "who does not even know day and
night." Upon the common herd of mortals he looks down with infinite
scorn. Some of his sayings remind us not a little of Schopenhauer in
their pungency and sharpness. "Asses prefer straw to {73} gold." "Dogs
bark at everyone they do not know." Many of his sayings, however, are
memorable and trenchant epitomes of practical wisdom. "Man's character
is his fate." "Physicians who cut, burn, stab and rack the sick,
demand a fee for doing it, which they do not deserve to get." From his
aloof and aristocratic standpoint he launched forth denunciations
against the democracy of Ephesus.
Heracleitus embodied his philosophical thoughts in a prose treatise,
which was well-known at the time of Socrates, but of which only
fragments have come down to us. His style soon became proverbial for
its difficulty and obscurity, and he gained the nickname of
Heracleitus the "Dark," or the "Obscure." Socrates said of his work
that what he understood of it was excellent, what not, he believed was
equally so, but that the book required a tough swimmer. He has even
been accused of intentional obscurity. But there does not seem to be
any foundation for this charge. The fact is that if he takes no great
trouble to explain his thoughts, neither does he take any trouble to
conceal them. He does not write for fools. His attitude appears to be
that if his readers understand him, well; if not, so much the worse
for his readers. He wastes no time in elaborating and explaining his
thought, but embodies it in short, terse, pithy, and pregnant sayings.
His philosophical principle is the direct antithesis of Eleaticism.
The Eleatics had taught that only Being is, and Becoming is not at
all. All change, all Becoming is mere illusion. For Heracleitus, on
the contrary, only Becoming is, and Being, permanence, identity, these
are nothing but illusion. All things sublunary are {74} perpetually
changing, passing over into new forms and new shapes. Nothing stands,
nothing holds fast, nothing remains what it is. "Into the same river,"
he says, "we go down, and we do not go down; for into the same river
no man can enter twice; ever it flows in and flows out." Not only does
he deny all absolute permanence, but even a relative permanence of
things is declared to be illusory. We all know that everything has its
term, that all things arise and pass away, from the insects who live
an hour to the "eternal" hills. Yet we commonly attribute to these
things at least a relative permanence, a shorter or longer continuance
in the same state. But even this Heracleitus will not allow. Nothing
is ever the same, nothing remains identical from one consecutive
moment to another. The appearance of relative permanence is an
illusion, like that which makes us think that a wave passing over the
surface of the water remains all the time the same identical wave.
Here, as we know, the water of which the wave is composed changes from
moment to moment, only the form remaining the same. Precisely so, for
Heracleitus, the permanent appearance of things results from the
inflow and outflow in them of equivalent quantities of substance. "All
is flux." It is not, for example, the same sun which sets to-day and
rises to-morrow. It is a new sun. For the fire of the sun burns itself
out and is replenished from the vapours of the sea.
Not only do things change from moment to moment. Even in one and the
same moment they are and are not the same. It is not merely that a
thing first is, and then a moment afterwards, is not. It both is and
is not at the same time. The at-onceness of "is" and "is not" {75} is
the meaning of Becoming. We shall understand this better if we
contrast it with the Eleatic principle. The Eleatics described all
things under two concepts, Being and not-being. Being has, for them,
all truth, all reality. Not-being is wholly false and illusory. For
Heracleitus both Being and not-being are equally real. The one is as
true as the other. Both are true, for both are identical. Becoming is
the identity of Being and not-being. For Becoming has only two forms,
namely, the arising of things and their passing away, their beginning
and their end, their origination and their decease. Perhaps you may
think that this is not correct, that there are other forms of change
besides origination and decease. A man is born. That is his
origination. He dies. That is his decease. Between his birth and his
death there are intermediate changes. He grows larger, grows older,
grows wiser or more foolish, his hair turns grey. So also the leaf of
a tree does not merely come into being and pass out of being. It
changes in shape, form, colour. From light green it becomes dark
green, and from dark green, yellow. But there is after all nothing in
all this except origination and decease, not of the thing itself, but
of its qualities. The change from green to yellow is the decease of
green colour, the origination of yellow colour. Origination is the
passage of not-being into Being. Decease is the passage of Being into
not-being. Becoming, then, has in it only the two factors of Being and
not-being, and it means the passing of one into the other. But this
passage does not mean, for Heracleitus, that at one moment there is
Being, and at the next moment not-being. It means that Being and
not-being are in everything at one and the same time. Being is {76}
not-being. Being has not-being in it. Take as an example the problem
of life and death. Ordinarily we think that death is due to external
causes, such as accident or disease. We consider that while life
lasts, it is what it is, and remains what it is, namely life, unmixed
with death, and that it goes on being life until something comes from
outside, as it were, in the shape of external causes, and puts an end
to it. You may have read Metchnikoff's book "The Nature of Man." In
the course of that book he develops this idea. Death, he says, is
always due to external causes. Therefore, if we could remove the
causes, we could conquer death. The causes of death are mostly disease
and accident, for even old age is disease. There is no reason why
science should not advance so far as to eliminate disease and accident
from life. In that case life might be made immortal, or at any rate,
indefinitely prolonged. Now this is founded upon a confusion of ideas.
No doubt death is always due to external causes. Every event in the
world is determined, and wholly determined, by causes. The law of
causation admits of no exception whatever. Therefore it is perfectly
true that in every case of death causes precede it. But, as I
explained in the last chapter, [Footnote 6] to give the cause is not
to give any reason for an event. Causation is never a principle of
explanation of anything. It tells us that the phenomenon A is
invariably and unconditionally followed by the phenomenon B, and we
call A the cause of B. But this only means that whenever B happens, it
happens in a certain regular order and succession of events. But it
does not tell us why B happens at all. The reason of a thing is to be
{77} distinguished from its cause. The reason why a man dies is not to
be found in the causes which bring about his death. The reason rather
is that life has the germ of death already in it, that life is already
death potentially, that Being has not-being in it. The causation of
death is merely the mechanism, by the instrumentality of which,
through one set of causes or another, the inevitable end is brought
about.
[Footnote 6: Page 64.]
Not only is Being, for Heracleitus, identical with not-being, but
everything in the universe has in it its own opposite. Every existent
thing is a "harmony of opposite tensions." A harmony contains
necessarily two opposite principles which, in spite of their
opposition, reveal an underlying unity. That it is by virtue of this
principle that everything in the universe exists, is the teaching of
Heracleitus. All things contain their own opposites within them. In
the struggle and antagonism between hostile principles consists their
life, their being, their very existence. At the heart of things is
conflict. If there were no conflict in a thing, it would cease to
exist. This idea is expressed by Heracleitus in a variety of ways.
"Strife," he says, "is the father of all things." "The one, sundering
from itself, coalesces with itself, like the harmony of the bow and
the lyre." "God is day and night, summer and winter, war and peace,
satiety and hunger." "Join together whole and unwhole, congruous and
incongruous, accordant and discordant, then comes from one all and
from all one." In this sense, too, he censures Homer for having prayed
that strife might cease from among gods and men. If such a prayer were
granted, the universe itself would pass away.
{78}
Side by side with this metaphysic, Heracleitus lays down a theory of
physics. All things are composed of fire. "This world," he says,
"neither one of the gods nor of the human race has made; but it is, it
was, and ever shall be, an eternally living fire." All comes from
fire, and to fire all returns. "All things are exchanged for fire and
fire for all, as wares for gold and gold for wares." Thus there is
only one ultimate kind of matter, fire, and all other forms of matter
are merely modifications and variations of fire. It is clear for what
reason Heracleitus enunciated this principle. It is an exact physical
parallel to the metaphysical principle of Becoming. Fire is the most
mutable of the elements. It does not remain the same from one moment
to another. It is continually taking up matter in the form of fuel,
and giving off equivalent matter in the form of smoke and vapour. The
primal fire, according to Heracleitus, transmutes itself into air, air
into water, and water into earth. This he calls "the downward path."
To it corresponds "the upward path," the transmutation of earth into
water, water to air, and air to fire. All transformation takes place
in this regular order, and therefore, says Heracleitus, "the upward
and the downward path are one."
Fire is further specially identified with life and reason. It is the
rational element in things. The more fire there is, the more life, the
more movement. The more dark and heavy materials there are, the more
death, cold, and not-being. The soul, accordingly, is fire, and like
all other fires it continually burns itself out and needs
replenishment. This it obtains, through the senses and the breath,
from the common life and reason of the {79} world, that is, from the
surrounding and all-pervading fire. In this we live and move and have
our being. No man has a separate soul of his own. It is merely part of
the one universal soul-fire. Hence if communication with this is cut
off, man becomes irrational and finally dies. Sleep is the half-way
house to death. In sleep the passages of the senses are stopped up,
and the outer fire reaches us only through breath. Hence in sleep we
become irrational and senseless, turning aside from the common life of
the world, each to a private world of his own. Heracleitus taught also
the doctrine of periodic world-cycles. The world forms itself out of
fire, and by conflagration passes back to the primitive fire.
In his religious opinions Heracleitus was sceptical. But he does not,
like Xenophanes, direct his attacks against the central ideas of
religion, and the doctrine of the gods. He attacks mostly the outward
observances and forms in which the religious spirit manifests itself.
He inveighs against the worship of images, and urges the uselessness
of blood sacrifice.
With the Eleatics he distinguishes between sense and reason, and
places truth in rational cognition. The illusion of permanence he
ascribes to the senses. It is by reason that we rise to the knowledge
of the law of Becoming. In the comprehension of this law lies the duty
of man, and the only road to happiness. Understanding this, man
becomes resigned and contented. He sees that evil is the necessary
counterpart of good, and pain the necessary counterpart of pleasure,
and that both together are necessary to form the harmony of the world.
Good and evil are principles on the struggle {80} between which the
very existence of things depends. Evil, too, is necessary, has its
place in the world. To see this is to put oneself above pitiful and
futile struggles against the supreme law of the universe.
CHAPTER VI
EMPEDOCLES
Empedocles was a man of Agrigentum in Sicily. The dates of his birth
and death are placed about 495 and 435 B.C. respectively. Like
Pythagoras, he possessed a powerful and magnetic personality. Hence
all kinds of legends quickly grew up and wove themselves round his
life and death. He was credited with the performance of miracles, and
romantic stories were circulated about his death. A man of much
persuasive eloquence he raised himself to the leadership of the
Agrigentine democracy, until he was driven out into exile.
The philosophy of Empedocles is eclectic in character. Greek
philosophy had now developed a variety of conflicting principles, and
the task of Empedocles is to reconcile these, and to weld them
together in a new system, containing however no new thought of its
own. In speaking of Parmenides, I pointed out that his teaching may be
interpreted either in an idealistic or a materialistic sense, and that
these two aspects of thought lie side by side in Parmenides, and that
it is possible to emphasize either the one or the other. Empedocles
seizes upon the materialistic side. The essential thought of
Parmenides was that Being cannot pass into not-being, nor not-being
into Being. Whatever is, remains for ever what it is. {82} If we take
that in a purely material context, what it means is that matter has
neither beginning nor end, is uncreated and indestructible. And this
is the first basic principle of Empedocles. On the other hand,
Heracleitus had shown that becoming and change cannot be denied. This
is the second basic principle of Empedocles. That there is no absolute
becoming, no creation, and utter destruction of things, and yet that
things do somehow arise and pass away, this must be explained, these
contradictory ideas must be reconciled. Now if we assert that matter
is uncreated and indestructible, and yet that things arise and pass
away, there is only one way of explaining this. We must suppose that
objects, as wholes begin and cease to be, but that the material
particles of which they are composed are uncreated and indestructible.
This thought now forms the first principle of Empedocles, and of his
successors, Anaxagoras, and the Atomists.
Now the Ionic philosophers had taught that all things are composed of
some one ultimate matter. Thales believed it to be water, Anaximenes
air. This necessarily involved that the ultimate kind of matter must
be capable of transformation into other kinds of matter. If it is
water, then water must be capable of turning into brass, wood, iron,
air, or whatever other kind of matter exists. And the same thing
applies to the air of Anaximenes. Parmenides, however, had taught that
whatever is, remains always the same, no change or transformation
being possible. Empedocles here too follows Parmenides, and interprets
his doctrine in his own way. One kind of matter, he thinks, can never
change into another kind of matter; fire never becomes {83} water, nor
does earth ever become air. This leads Empedocles at once to a
doctrine of elements. The word "elements," indeed, is of later
invention, and Empedocles speaks of the elements as "the roots of
all." There are four elements, earth, air, fire, and water. Empedocles
was therefore the originator of the familiar classification of the
four elements. All other kinds of matter are to be explained as
mixtures, in various proportions, of these four. Thus all origination
and decease, as well as the differential qualities of certain kinds of
matter, are now explained by the mixing and unmixing of the four
elements. All becoming is simply composition and decomposition.
But the coming together and separation of the elements involves the
movement of particles, and to explain this there must exist some
moving force. The Ionic philosophers had assumed that matter has the
power or force required for movement immanent in itself. The air of
Anaximenes, of its own inherent power, transforms itself into other
kinds of matter. This doctrine Empedocles rejects. Matter is for him
absolutely dead and lifeless, without any principle of motion in
itself. There is, therefore, only one remaining possibility. Forces
acting upon matter from the outside must be assumed. And as the two
essential processes of the world, mixing and unmixing, are opposite in
character, so there must be two opposite forces. These he calls by the
names Love and Hate, or Harmony and Discord. Though these terms may
have an idealistic sound, Empedocles conceives them as entirely
physical and material forces. But he identifies the attractions and
repulsions of human beings, which we call love and hate, with the
universally operating forces of the material world. Human love and
{84} hate are but the manifestations in us of the mechanical forces of
attraction and repulsion at work in the world at large.
Empedocles taught the doctrine of periodic world-cycles. The
world-process is, therefore, properly speaking, circular, and has
neither beginning nor end. But in describing this process one must
begin somewhere. We will begin, then, with the sphairos (sphere). In
the primeval sphere the four elements are completely mixed, and
interpenetrate each other completely. Water is not separated off from
air, nor air from earth. All are chaotically mixed together. In any
portion of the sphere there must be an equal quantity of earth, air,
fire and water. The elements are thus in union, and the sole force
operative within the sphere is Love or Harmony. Hence the sphere is
called a "blessed god." Hate, however, exists all round the outside of
the sphere. Hate gradually penetrates from the circumference towards
the centre and introduces the process of separation and disunion of
the elements. This process continues till, like coming together with
like, the elements are wholly separated. All the water is together;
all the fire is together, and so on. When this process of
disintegration is complete, Hate is supreme and Love is entirely
driven out. But Love again begins to penetrate matter, to cause union
and mixture of the elements, and finally brings the world back to the
state of the original sphere. Then the same process begins again. At
what position in this circular movement is our present world to be
placed? The answer is that it is neither in the complete union of the
sphere, nor is it completely disintegrated. It is half-way between the
sphere and the stage of total {85} disintegration. It is proceeding
from the former towards the later, and Hate is gradually gaining the
upper hand. In the formation of the present world from the sphere the
first element to be separated off was air, next fire, then the earth.
Water is squeezed out of the earth by the rapidity of its rotation.
The sky is composed of two halves. One is of fire, and this is the
day. The other is dark matter with masses of fire scattered about in
it, and this is the night.
Empedocles believed in the transmigration of souls. He also put
forward a theory of sense-perception, the essential of which is that
like perceives like. The fire in us perceives external fire, and so
with the other elements. Sight is caused by effluences of the fire and
water of the eyes meeting similar effluences from external objects.
{86}
CHAPTER VII
THE ATOMISTS
The founder of the Atomist philosophy was Leucippus. Practically
nothing is known of his life. The date of his birth, the date of his
death, and his place of residence, are alike unknown, but it is
believed that he was a contemporary of Empedocles and Anaxagoras.
Democritus was a citizen of Abdera in Thrace. He was a man of the
widest learning, as learning was understood in his day. A passion for
knowledge and the possession of adequate means for the purpose,
determined him to undertake extensive travels in order to acquire the
wisdom and knowledge of other nations. He travelled largely in Egypt,
also probably in Babylonia. The date of his death is unknown, but he
certainly lived to a great age, estimated at from ninety to one
hundred years. Exactly what were the respective contributions of
Leucippus and Democritus to the Atomist philosophy, is also a matter
of doubt. But it is believed that all the essentials of this
philosophy were the work of Leucippus, and that Democritus applied and
extended them, worked out details, and made the theory famous.
Now we saw that the philosophy of Empedocles was based upon an attempt
to reconcile the doctrine of Parmenides with the doctrine of
Heracleitus. The {87} fundamental thought of Empedocles was that there
is no absolute becoming in the strict sense, no passage of Being into
not-being or not-being into Being. Yet the objects of the senses do,
in some way, arise and pass away, and the only method by which this is
capable of explanation is to suppose that objects, as whole objects,
come to be and cease to be, but that the material particles of which
they are composed are eternally existent. But the detailed development
which Empedocles gave to this principle was by no means satisfactory.
In the first place, if we hold that all objects are composed of parts,
and that all becoming is due to the mixing and unmixing of
pre-existent matter, we must have a theory of particles. And we do
hear vaguely of physical particles in the doctrine of Empedocles, but
no definition is given of their nature, and no clear conception is
formed of their character. Secondly, the moving forces of Empedocles,
Love and Hate, are fanciful and mythological. Lastly, though there are
in Empedocles traces of the doctrine that the qualities of things
depend on the position and arrangement of their particles, this idea
is not consistently developed. For Empedocles there are only four
ultimate kinds of matter, qualitatively distinguished. The
differential qualities of all other kinds of matter must, therefore,
be due to the mixing of these four elements. Thus the qualities of the
four elements are ultimate and underived, but all other qualities must
be founded upon the position and arrangement of particles of the four
elements. This is the beginning of the mechanical explanation of
quality. But to develop this theory fully and consistently, it should
be shown, not merely that some qualities are ultimate and some {88}
derived from position and arrangement of particles, but that all
quality whatever is founded upon position and arrangement. All
becoming is explained by Empedocles as the result of motion of
material particles. To bring this mechanical philosophy to its logical
conclusion, all qualitativeness of things must be explained in the
same way. Hence it was impossible that the philosophy of mechanism and
materialism should stand still in the position in which Empedocles
left it. It had to advance to the position of Atomism. The Atomists,
therefore, maintain the essential position of Empedocles, after
eliminating the inconsistencies which we have just noted. The
philosophy of Empedocles is therefore to be considered as merely
transitional in character.
First, the Atomists developed the theory of particles. According to
Leucippus and Democritus, if matter were divided far enough, we should
ultimately come to indivisible units. These indivisible units are
called atoms, and atoms are therefore the ultimate constituents of
matter. They are infinite in number, and are too small to be
perceptible to the senses. Empedocles had assumed four different kinds
of matter. But, for the Atomists, there is only one kind. All the
atoms are composed of exactly the same kind of matter. With certain
exceptions, which I will mention in a moment, they possess no quality.
They are entirely non-qualitative, the only differences between them
being differences of quantity. They differ in size, some being larger,
some smaller. And they likewise differ in shape. Since the ultimate
particles of things thus possess no quality, all the actual qualities
of objects must be due to the {89} arrangement and position of the
atoms. This is the logical development of the tentative mechanism of
Empedocles.
I said that the atoms possess no qualities. They must, however, be
admitted to possess the quality of solidity, or impenetrability, since
they are defined as being indivisible. Moreover it is a question
whether the atoms of Democritus and Leucippus were thought to possess
weight, or whether the weight of objects is to be explained, like
other qualities, by the position and movement of the atoms. There is
no doubt that the Epicureans of a later date considered the atoms to
have weight. The Epicureans took over the atomism of Democritus and
Leucippus, with few modifications, and made it the basis of their own
teaching. They ascribed weight to the atoms, and the only question is
whether this was a modification introduced by them, or whether it was
part of the original doctrine of Democritus and Leucippus.
The atoms are bounded, and separated off from each other. Therefore,
they must be separated by something, and this something can only be
empty space. Moreover, since all becoming and all qualitativeness of
things are to be explained by the mixing and unmixing of atoms, and
since this involves movement of the atoms, for this reason also empty
space must be assumed to exist, for nothing can move unless it has
empty space to move in. Hence there are two ultimate realities, atoms
and empty space. These correspond respectively to the Being and
not-being of the Eleatics. But whereas the latter denied any reality
to not-being, the Atomists affirm that not-being, that is, empty
space, is just as real as being. Not-being also exists. "Being," said
{90} Democritus, "is by nothing more real than nothing." The atoms
being non-qualitative, they differ in no respect from empty space,
except that they are "full." Hence atoms and the void are also called
the _plenum_ and the _vacuum_.
How, now, is the movement of the atoms brought about? Since all
becoming is due to the separation and aggregation of atoms, a moving
force is required. What is this moving force? This depends upon the
question whether atoms have weight. If we assume that they have
weight, then the origin of the world, and the motion of atoms, becomes
clear. In the system of the Epicureans the original movement of the
atoms is due to their weight, which causes them to fall perpetually
downwards through infinite space. Of course the Atomists had no true
ideas of gravitation, nor did they understand that there is no
absolute up and down. The large atoms are heavier than the smaller.
The matter of which they are composed is always the same. Therefore,
volume for volume, they weigh the same. Their weight is thus
proportional to their size, and if one atom is twice as large as
another, it will also be twice as heavy. Here the Atomists made
another mistake, in supposing that heavier things fall in a vacuum
more quickly than light things. They fall, as a matter of fact, with
the same speed. But according to the Atomists, the heavier atoms,
falling faster, strike against the lighter, and push them to one side
and upwards. Through this general concussion of atoms a vortex is
formed, in which like atoms come together with like. From the
aggregation of atoms worlds are created. As space is infinite and the
atoms go on falling eternally, there must have been innumerable worlds
of which our world is only one. {91} When the aggregated atoms fall
apart again, this particular world will cease to exist. But all this
depends upon the theory that the atoms have weight. According to
Professor Burnet, however, the weight of atoms is a later addition of
the Epicureans. If that is so, it is very difficult to say how the
early Atomists, Leucippus and Democritus, explained the original
motion. What was their moving force, if it was not weight? If the
atoms have no weight, their original movement cannot have been a fall.
"It is safest to say," says Professor Burnet, "that it is simply a
confused motion this way and that." [Footnote 7] Probably this is a
very _safe_ thing to say, because it means nothing in particular. Motion
itself cannot be confused. It is only our ideas of motion which can be
confused. If this theory is correct, then, we can only say that the
Atomists had no definite solution of the problem of the origin of
motion and the character of the moving force. They apparently saw no
necessity for explanation, which seems unlikely in view of the fact
that Empedocles had already seen the necessity of solving the problem,
and given a definite, if unsatisfactory, solution, in his theory of
Love and Hate. This remark would apply to Democritus, if not to
Leucippus.
[Footnote 7: _Early Greek Philosophy_, chap. ix. § 179.]
The Atomists also spoke of all movement being under the force of
"necessity." Anaxagoras was at this time teaching that all motion of
things is produced by a world-intelligence, or reason. Democritus
expressly opposes to this the doctrine of necessity. There is no
reason or intelligence in the world. On the contrary, all phenomena
and all becoming are completely determined by blind mechanical causes.
In this connection there arises {92} among the Atomists a polemic
against the popular gods and the popular religion. Belief in gods
Democritus explains as being due to fear of great terrestrial and
astronomical phenomena, such as volcanoes, earthquakes, comets, and
meteors. But somewhat inconsistently with this, Democritus believed
that the air is inhabited by beings resembling men, but larger and of
longer life, and explained belief in the gods as being due to
projection from these of images of themselves composed of atoms which
impinge upon human senses, and produce the ideas of gods.
Different kinds of matter must be explained, in any atomic theory, by
the shape, size, and position of the atoms of which they are composed.
Thus the Atomists taught that fire is composed of smooth round atoms.
The soul is also composed of smooth round atoms, and is an
exceptionally pure and refined fire. At death the soul atoms are
scattered, and hence there is, of course, no question of a future
life. Democritus also put forward a theory of perception, according to
which objects project into space images of themselves composed of
atoms. These images strike against the senses. Like atoms are
perceived by like. Thought is true when the soul is equable in
temperature. The sensible qualities of things, such as smell, taste,
colour, do not exist in the things themselves, but merely express the
manner in which they affect our senses, and are therefore relative to
us. A number of the ethical maxims of Democritus have come down to us.
But they are not based in any way upon the Atomic theory, and cannot
be deduced from it. Hence they have no scientific foundation but are
merely detached sayings, epitomizing the experience {93} and worldly
wisdom of Democritus. That one should enjoy oneself as much and vex
oneself as little as possible seems to have been his principal idea.
This, however, is not to be interpreted in any low, degraded, or
sensual way. On the contrary, Democritus says that the happiness of
man does not depend on material possessions, but upon the state of the
soul. He praises equanimity and cheerfulness, and these are best
attained, he thinks, by moderation and simplicity.
{94}
CHAPTER VIII
ANAXAGORAS
Anaxagoras was born at Clazomenae in Asia Minor about 500 B.C. He was
a man of noble family, and possessed considerable property. He
neglected his property in the search for knowledge and in the pursuit
of science and philosophy. Leaving his home at Clazomenae, he settled
down in Athens. We have not heard so far anything of Athens in the
history of Greek Philosophy. It was Anaxagoras who transplanted
philosophy to Athens, which from his time forward became the chief
centre of Greek thought. At Athens, Anaxagoras came into contact with
all the famous men of the time. He was an intimate friend of Pericles,
the statesman, and of Euripides, the poet. But his friendship with
Pericles cost him dear. There was a strong political faction opposed
to Pericles. So far as we know Anaxagoras never meddled in politics,
but he was a friend of the statesman Pericles, and that was quite
enough. The enemies of Pericles determined to teach Anaxagoras a
lesson, and a charge of atheism and blasphemy was accordingly brought
against him. The particulars of the charge were that Anaxagoras said
that the sun was a red-hot stone, and that the moon was made of earth.
This was quite true, as that is exactly what Anaxagoras did say of the
sun and the moon. But the Greeks {95} regarded the heavenly bodies as
gods; even Plato and Aristotle thought that the stars were divine
beings. To call the sun a red-hot stone, and to say that the moon was
made of earth, was therefore blasphemy according to Greek ideas.
Anaxagoras was charged, tried, and condemned. The details of the
trial, and of what followed, are not known with accuracy. But it
appears that Anaxagoras escaped, probably with the help of Pericles,
and from Athens went back to his native country in Asia Minor. He
settled at Lampsacus, and died there at the age of 72. He was the
author of a treatise in which he wrote down his philosophical ideas.
This treatise was well-known at the time of Socrates, but only
fragments now remain.
The foundation of the philosophy of Anaxagoras is the same as that of
Empedocles and the Atomists. He denied any absolute becoming in the
strict sense of the passing of being into not-being and not-being into
being. Matter is uncreated and indestructible, and all becoming must
be accounted for by the mixing and unmixing of its component parts.
This principle Anaxagoras himself expressed with great clearness, in a
fragment of his treatise which has come down to us. "The Greeks," he
says, "erroneously assume origination and destruction, for nothing
originates and nothing is destroyed. All is only mixed and unmixed out
of pre-existent things, and it were more correct to call the one
process composition and the other process decomposition."
The Atomists had assumed the ultimate constituents of things to be
atoms composed of the same kind of matter. Empedocles had believed in
four ultimate and underived kinds of matter. With neither of these
does Anaxagoras agree. For him, all the different kinds of {96} matter
are equally ultimate and underived, that is to say, such things as
gold, bone, hair, earth, water, wood, etc., are ultimate kinds of
matter, which do not arise from anything else, and do not pass over
into one another. He also disagrees with the conception of the
Atomists that if matter is divided far enough, ultimate and
indivisible particles will be reached. According to Anaxagoras matter
is infinitely divisible. In the beginning all these kinds of matter
were mixed together in a chaotic mass. The mass stretches infinitely
throughout space. The different kinds of matter wholly intermingle and
interpenetrate each other. The process of world-formation is brought
about by the unmixing of the conglomeration of all kinds of matter,
and the bringing together of like matter with like. Thus the gold
particles separating out of the mass come together, and form gold; the
wood particles come together and form wood, and so on. But as matter
is infinitely divisible and the original mixing of the elements was
complete, they were, so to speak, mixed to an infinite extent.
Therefore the process of unmixing would take infinite time, is now
going on, and will always go on. Even in the purest element there is
still a certain admixture of particles of other kinds of matter. There
is no such thing as pure gold. Gold is merely matter in which the gold
particles predominate.
As with Empedocles and the Atomists, a moving force is required to
explain the world-process of unmixing. What, in the philosophy of
Anaxagoras, is this force? Now up to the present point the philosophy
of Anaxagoras does not rise above the previous philosophies of
Empedocles and the Atomists. On the contrary, in clearness {97} and
logical consistency, it falls considerably below the teaching of the
latter. But it is just here, on the question of the moving force, that
Anaxagoras becomes for the first time wholly original, and introduces
a principle peculiar to himself, a principle, moreover, which is
entirely new in philosophy. Empedocles had taken as his moving forces,
Love and Hate, mythical and fanciful on the one hand, and yet purely
physical on the other. The forces of the Atomists were also completely
material. But Anaxagoras conceives the moving force as wholly
non-physical and incorporeal. It is called Nous, that is, mind or
intelligence. It is intelligence which produces the movement in things
which brings about the formation of the world. What was it, now, which
led Anaxagoras to the doctrine of a world-governing intelligence? It
seems that he was struck with the apparent design, order, beauty and
harmony of the universe. These things, he thought, could not be
accounted for by blind forces. The world is apparently a rationally
governed world. It moves towards definite ends. Nature shows plentiful
examples of the adaptation of means to ends. There appears to be plan
and purpose in the world. The Atomists had assumed nothing but matter
and physical force. How can design, order, harmony and beauty be
brought about by blind forces acting upon chaotic matter? Blind forces
acting upon a chaos would produce motion and change. But the change
would be meaningless and purposeless. They could not produce a
rationally ordered cosmos. One chaos would succeed another chaos ad
infinitum. That alone which can produce law and order is intelligence.
There must therefore be a world-controlling Nous.
{98}
What is the character of the Nous, according to Anaxagoras? Is it, in
the first place, really conceived as purely non-material and
incorporeal? Aristotle, who was in a position to know more of the
matter than any modern scholar, clearly implies in his criticism that
the Nous of Anaxagoras is an incorporeal principle, and he has been
followed in this by the majority of the best modern writers, such as
Zeller and Erdmann. But the opposite view has been maintained, by
Grote, for example, and more recently by Professor Burnet, who thinks
that Anaxagoras conceived the Nous as a material and physical force.
[Footnote 8] As the matter is of fundamental importance, I will
mention the chief arguments upon which Professor Burnet rests his
case. In the first place Anaxagoras described the Nous as the
"thinnest and purest of all things." He also said that it was
"unmixed," that it had in it no mixture of anything besides itself.
Professor Burnet argues that such words as "thin" and "unmixed" would
be meaningless in connection with an incorporeal principle. Only
material things can properly be described as thin, pure, and unmixed.
Secondly, Professor Burnet thinks that it is quite certain that the
Nous occupies space, for Anaxagoras speaks of greater and smaller
portions of it. Greater and smaller are spatial relations. Hence the
Nous occupies space, and that which occupies space is material. But
surely these are very inconclusive arguments. In the first place as
regards the use of the words "thin" and "unmixed." It is true that
these terms express primarily physical qualities. But, as I pointed
out in {99} the first chapter, almost all words by which we seek to
express incorporeal ideas have originally a physical signification.
And if Anaxagoras is to be called a materialist because he described
the Nous as thin, then we must also plead guilty to materialism if we
say that the thought of Plato is "luminous," or that the mind of
Aristotle is "clear." The fact is that all philosophy labours under
the difficulty of having to express non-sensuous thought in language
which has been evolved for the purpose of expressing sensuous ideas.
There is no philosophy in the world, even up to the present day, in
which expressions could not be found in plenty which are based upon
the use of physical analogies to express entirely non-physical ideas.
Then as regards the Nous occupying space, it is not true that greater
and smaller are necessarily spatial relations. They are also
qualitative relations of degree. I say that the mind of Plato is
greater than the mind of Callias. Am I to be called a materialist? Am
I to be supposed to mean that Plato's mind occupies more space than
that of Callias? And it is certainly in this way that Anaxagoras uses
the terms. "All Nous," he says, "is alike, both the greater and the
smaller." He means thereby that the world-forming mind (the greater)
is identical in character with the mind of man (the smaller). For
Anaxagoras it is the one Nous which animates all living beings, men,
animals, and even plants. These different orders of beings are
animated by the same Nous but in different degrees, that of man being
the greatest. But this does not mean that the Nous in man occupies
more space than the Nous in a plant. But even if Anaxagoras did
conceive the Nous as spatial, it does not follow that he {100}
regarded it as material. The doctrine of the non-spatiality of mind is
a modern doctrine, never fully developed till the time of Descartes.
And to say that Anaxagoras did not realize that mind is non-spatial is
merely to say that he lived before the time of Descartes. No doubt it
would follow from this that the incorporeality of mind is vaguely and
indistinctly conceived by Anaxagoras, that the antithesis between
matter and mind is not so sharply drawn by him as it is by us. But
still the antithesis is conceived, and therefore it is correct to say
that the Nous of Anaxagoras is an incorporeal principle. The whole
point of this introduction of the Nous into the philosophy of
Anaxagoras is because he could not explain the design and order of the
universe on a purely physical basis.
[Footnote 8: _Early Greek Philosophy_, chap. vi. § 132.]
The next characteristic of Nous is that it is to be thought of as
essentially the ground of motion. It is because he cannot in any other
way explain purposive motion that Anaxagoras introduces mind into his
otherwise materialistic system. Mind plays the part of the moving
force which explains the world-process of unmixing. As the ground of
motion, the Nous is itself unmoved; for if there were any motion in it
we should have to seek for the ground of this motion in something else
outside it. That which is the cause of all motion, cannot itself be
moved. Next, the Nous is absolutely pure and unmixed with anything
else. It exists apart, by itself, wholly in itself, and for itself. In
contrast to matter, it is uncompounded and simple. It is this which
gives it omnipotence, complete power over everything, because there is
no mixture of matter in it to limit it, to clog and hinder its
activities. We moderns are {101} inclined to ask the question whether
the Nous is personal. Is it, for example, a personal being like the
God of the Christians? This is a question which it is almost
impossible to answer. Anaxagoras certainly never considered it.
According to Zeller, the Greeks had an imperfect and undeveloped
conception of personality. Even in Plato we find the same difficulty.
The antithesis between God as a personal and as an impersonal being,
is a wholly modern idea. No Greek ever discussed it.
To come now to the question of the activity of the Nous and its
function in the philosophy of Anaxagoras, we must note that it is
essentially a world-forming, and not a world-creating, intelligence.
The Nous and matter exist side by side from eternity. It does not
create matter, but only arranges it. "All things were together," says
Anaxagoras, "infinitely numerous, infinitely little; then came the
Nous and set them in order." In this Anaxagoras showed a sound logical
sense. He based his idea of the existence of Nous upon the design
which exhibits itself in the world. In modern times the existence of
design in the world has been made the foundation of an argument for
the existence of God, which is known as the teleological argument. The
word teleology means the view of things as adapting means towards
purposive ends. To see intelligent design in the universe is to view
the universe teleologically. And the teleological argument for the
existence of God asserts that, as there is evidence of purpose in
nature, this must be due to an intelligent cause. But, as a matter of
fact, taken by itself, teleology cannot possibly be made the basis of
an argument for the existence of a world-creating intelligence, but
only for the existence of a world-designing {102} intelligence. If you
find in the desert the ruins of ancient cities and temples, you are
entitled to conclude therefrom, that there existed a mind which
designed these cities and buildings, and which arranged matter in that
purposive way, but you are not entitled to conclude that the mind
which designed the cities also created the matter out of which they
were made. Anaxagoras was, therefore, in that sense quite right.
Teleology is not evidence of a world-creating mind, and if we are to
prove that, we must have recourse to other lines of reasoning.
In the beginning, then, there was a chaotic mixture of different kinds
of matter. The Nous produced a vortex at one point in the middle of
this mass. This vortex spread itself outwards in the mass of matter,
like rings caused by the fall of a stone in water. It goes on for ever
and continually draws more and more matter out of the infinite mass
into itself. The movement, therefore, is never-ending. It causes like
kinds of matter to come together with like, gold to gold, wood to
wood, water to water, and so on. It is to be noted, therefore, that
the action of the Nous is apparently confined to the first movement.
It acts only at the one central point, and every subsequent movement
is caused by the vortex itself, which draws in more and more of the
surrounding matter into itself. First are separated out the warm, dry,
and light particles, and these form the aether or upper air. Next come
the cold, moist, dark, and dense particles which form the lower air.
Rotation takes the latter towards the centre, and out of this the
earth is formed. The earth, as with Anaximenes, is a flat disc, borne
upon the air. The heavenly bodies consist of {103} masses of stone
which have been torn from the earth by the force of its rotation, and
being projected outwards become incandescent through the rapidity of
their movement. The moon is made of earth and reflects the light of
the sun. Anaxagoras was thus the first to give the true cause of the
moon's light. He was also the first to discover the true theory of
eclipses, since he taught that the solar eclipse is due to the
intervention of the moon between the sun and the earth, and that lunar
eclipses arise from the shadow of the earth falling upon the moon. He
believed that there are other worlds besides our own with their own
suns and moons. These worlds are inhabited. The sun, according to
Anaxagoras, is many times as large as the Peloponnese. The origin of
life upon the earth is accounted for by germs which existed in the
atmosphere, and which were brought down into the terrestrial slime by
rain water, and there fructified. Anaxagoras's theory of perception is
the opposite of the theories of Empedocles and the Atomists.
Perception takes place by unlike matter meeting unlike.
Anaxagoras owes his importance in the history of philosophy to the
theory of the Nous. This was the first time that a definite
distinction had been made between the corporeal and incorporeal.
Anaxagoras is the last philosopher of the first period of Greek
philosophy. In the second chapter, [Footnote 9] I observed that this
first period is characterized by the fact that in it the Greek mind
looks only outward upon the external world. It attempts to explain the
operations of nature. It had not yet learned to look inward upon
itself. But the transition to the introspective study of mind is found
in the Nous of {104} Anaxagoras. Mind is now brought to the fore as a
problem for philosophy. To find reason, intelligence, mind, in all
things, in the State, in the individual, in external nature, this is
the characteristic of the second period of Greek philosophy. To have
formulated the antithesis between mind and matter is the most
important work of Anaxagoras.
[Footnote 9: Pages 23-4.]
Secondly, it is to the credit of Anaxagoras that he was the first to
introduce the idea of teleology into philosophy. The system of the
Atomists formed the logical completion of the mechanical theory of the
world. The theory of mechanism seeks to explain all things by causes.
But, as we saw, causation can explain nothing. The mechanism of the
world shows us by what means events are brought about, but it does not
explain why they are brought about at all. That can only be explained
by showing the reason for things, by exhibiting all process as a means
towards rational ends. To look to the beginning (cause) of things for
their explanation is the theory of mechanism. To look to their ends
for explanation of them is teleology. Anaxagoras was the first to have
dimly seen this. And for this reason Aristotle praises him, and,
contrasting him with the mechanists, Leucippus and Democritus, says
that he appears like "a sober man among vain babblers." The new
principle which he thus introduced into philosophy was developed, and
formed the central idea of Plato and Aristotle. To have realized the
twin antitheses of matter and mind, of mechanism and teleology, is the
glory of Anaxagoras.
But it is just here, in the development of these two ideas, that the
defects of his system make their appearance. Firstly, he so separated
matter and mind that {105} his philosophy ends in sheer dualism. He
assumes the Nous and matter as existing from the beginning, side by
side, as equally ultimate and underived principles. A monistic
materialism would have derived the Nous from matter, and a monistic
idealism would have derived matter from the Nous. But Anaxagoras does
neither. Each is left, in his theory, an inexplicable ultimate
mystery. His philosophy is, therefore, an irreconcilable dualism.
Secondly, his teleology turns out in the end to be only a new theory
of mechanism. The only reason which induces him to introduce the Nous
into the world, is because he cannot otherwise explain the origin of
movement. It is only the first movement of things, the formation of
the vortex, which he explains by mind. All subsequent process is
explained by the action of the vortex itself, which draws the
surrounding matter into itself. The Nous is thus nothing but another
piece of mechanism to account for the first impulse to motion. He
regards the Nous simply as a first cause, and thus the characteristic
of all mechanism, to look back to first causes, to the beginning,
rather than to the end of things for their explanation, appears here.
Aristotle, as usual, puts the matter in a nutshell. "Anaxagoras," he
says, "uses mind as a _deus ex machina_ to account for the formation
of the world, and whenever he is at a loss to explain why anything
necessarily is, he drags it in by force. But in other cases he assigns
as a cause for things anything else in preference to mind." [Footnote
10]

{106}
CHAPTER IX
THE SOPHISTS
The first period of Greek philosophy closes with Anaxagoras. His
doctrine of the world-forming intelligence introduced a new principle
into philosophy, the principle of the antithesis between corporeal
matter and incorporeal mind, and therefore, by implication, the
antithesis between nature and man. And if the first period of
philosophy has for its problem the origin of the world, and the
explanation of the being and becoming of nature, the second period of
philosophy opens, in the Sophists, with the problem of the position of
man in the universe. The teaching of the earlier philosophers was
exclusively cosmological, that of the Sophists exclusively humanistic.
Later in this second period, these two modes of thought come together
and fructify one another. The problem of the mind and the problem of
nature are subordinated as factors of the great, universal,
all-embracing, world-systems of Plato and Aristotle.
It is not possible to understand the activities and teaching of the
Sophists without some knowledge of the religious, political, and
social conditions of the time. After long struggles between the people
and the nobles, democracy had almost everywhere triumphed. But in
Greece democracy did not mean what we now mean by {107} that word. It
did not mean representative institutions, government by the people
through their elected deputies. Ancient Greece was never a single
nation under a single government. Every city, almost every hamlet, was
an independent State, governed only by its own laws. Some of these
States were so small that they comprised merely a handful of citizens.
All were so small that all the citizens could meet together in one
place, and themselves in person enact the laws and transact public
business. There was no necessity for representation. Consequently in
Greece every citizen was himself a politician and a legislator. In
these circumstances, partisan feeling ran to extravagant lengths. Men
forgot the interests of the State in the interests of party, and this
ended in men forgetting the interests of their party in their own
interests. Greed, ambition, grabbing, selfishness, unrestricted
egotism, unbridled avarice, became the dominant notes of the political
life of the time.
Hand in hand with the rise of democracy went the decay of religion.
Belief in the gods was almost everywhere discredited. This was partly
due to the moral worthlessness of the Greek religion itself. Any
action, however scandalous or disgraceful, could be justified by the
examples of the gods themselves as related by the poets and
mythologers of Greece. But, in greater measure, the collapse of
religion was due to that advance of science and philosophy which we
have been considering in these lectures. The universal tendency of
that philosophy was to find natural causes for what had hitherto been
ascribed to the action of the divine powers, and this could not but
have an undermining effect upon popular {108} belief. Nearly all the
philosophers had been secretly, and many of them openly, antagonistic
to the people's religion. The attack was begun by Xenophanes;
Heracleitus carried it on; and lastly Democritus had attempted to
explain belief in the gods as being caused by fear of gigantic
terrestrial and astronomical phenomena. No educated man any longer
believed in divination, auguries, and miracles. A wave of rationalism
and scepticism passed over the Greek people. The age became one of
negative, critical, and destructive thought. Democracy had undermined
the old aristocratic institutions of the State, and science had
undermined religious orthodoxy. With the downfall of these two pillars
of things established, all else went too. All morality, all custom,
all authority, all tradition, were criticised and rejected. What was
regarded with awe and pious veneration by their fore-fathers the
modern Greeks now looked upon as fit subjects for jest and mockery.
Every restraint of custom, law, or morality, was resented as an
unwarrantable restriction upon the natural impulses of man. What alone
remained when these were thrust aside were the lust, avarice, and
self-will of the individual.
The teaching of the Sophists was merely a translation into theoretical
propositions of these practical tendencies of the period. The Sophists
were the children of their time, and the interpreters of their age.
Their philosophical teachings were simply the crystallization of the
impulses which governed the life of the people into abstract
principles and maxims.
Who and what were the Sophists? In the first place, they were not a
school of philosophers. They are not to be compared, for example, with
the Pythagoreans or {109} Eleatics. They had not, as a school has, any
system of philosophy held in common by them all. None of them
constructed systems of thought. They had in common only certain loose
tendencies of thought. Nor were they, as we understand the members of
a school to be, in any close personal association with one another.
They were a professional class rather than a school, and as such they
were scattered over Greece, and nourished among themselves the usual
professional rivalries. They were professional teachers and educators.
The rise of the Sophists was due to the growing demand for popular
education, which was partly a genuine demand for light and knowledge,
but was mostly a desire for such spurious learning as would lead to
worldly, and especially political, success. The triumph of democracy
had brought it about that political careers were now open to the
masses who had hitherto been wholly shut out from them. Any man could
rise to the highest positions in the State, if he were endowed with
cleverness, ready speech, whereby to sway the passions of the mob, and
a sufficient equipment in the way of education. Hence the demand arose
for such an education as would enable the ordinary man to carve out a
political career for himself. It was this demand which the Sophists
undertook to satisfy. They wandered about Greece from place to place,
they gave lectures, they took pupils, they entered into disputations.
For these services they exacted large fees. They were the first in
Greece to take fees for the teaching of wisdom. There was nothing
disgraceful in this in itself, but it had never been customary. The
wise men of Greece had never accepted any payment for their wisdom.
Socrates, who never accepted any payment, {110} but gave his wisdom
freely to all who sought it, somewhat proudly contrasted himself with
the Sophists in this respect.
The Sophists were not, technically speaking, philosophers. They did
not specialise in the problems of philosophy. Their tendencies were
purely practical. They taught any subject whatever for the teaching of
which there was a popular demand. For example, Protagoras undertook to
impart to his pupils the principles of success as a politician or as a
private citizen. Gorgias taught rhetoric and politics, Prodicus
grammar and etymology, Hippias history, mathematics and physics. In
consequence of this practical tendency of the Sophists we hear of no
attempts among them to solve the problem of the origin of nature, or
the character of the ultimate reality. The Sophists have been
described as teachers of virtue, and the description is correct,
provided that the word virtue is understood in its Greek sense, which
did not restrict it to morality alone. For the Greeks, it meant the
capacity of a person successfully to perform his functions in the
State. Thus the virtue of a mechanic is to understand machinery, the
virtue of a physician to cure the sick, the virtue of a horse trainer
the ability to train horses. The Sophists undertook to train men to
virtue in this sense, to make them successful citizens and members of
the State.
But the most popular career for a Greek of ability at the time was the
political, which offered the attraction of high positions in the
State. And for this career what was above all necessary was eloquence,
or if that were unattainable, at least ready speech, the ability to
argue, to meet every point as it arose, if not with sound {111}
reasoning, then with quick repartee. Hence the Sophists very largely
concentrated their energies upon the teaching of rhetoric. In itself
this was good. They were the first to direct attention to the science
of rhetoric, of which they may be considered the founders. But their
rhetoric also had its bad side, which indeed, soon became its only
side. The aims of the young politicians whom they trained were, not to
seek out the truth for its own sake, but merely to persuade the
multitude of whatever they wished them to believe. Consequently the
Sophists, like lawyers, not caring for the truth of the matter,
undertook to provide a stock of arguments on any subject, or to prove
any proposition. They boasted of their ability to make the worse
appear the better reason, to prove that black is white. Some of them,
like Gorgias, asserted that it was not necessary to have any knowledge
of a subject to give satisfactory replies as regards it. And Gorgias
ostentatiously undertook to answer any question on any subject
instantly and without consideration. To attain these ends mere
quibbling, and the scoring of verbal points, were employed. Hence our
word "sophistry." The Sophists, in this way, endeavoured to entangle,
entrap, and confuse their opponents, and even, if this were not
possible, to beat them down by mere violence and noise. They sought
also to dazzle by means of strange or flowery metaphors, by unusual
figures of speech, by epigrams and paradoxes, and in general by being
clever and smart, rather than earnest and truthful. When a man is
young he is often dazzled by brilliance and cleverness, by paradox and
epigram, but as he grows older he learns to discount these things and
to care chiefly for the substance and {112} truth of what is said. And
the Greeks were a young people. They loved clever sayings. And this it
is which accounts for the toleration which they extended even to the
most patent absurdities of the Sophists. The modern question whether a
man has ceased beating his wife is not more childish than many of the
rhetorical devices of the Sophists, and is indeed characteristic of
the methods of the more extravagant among them.
The earliest known Sophist is Protagoras. He was born at Abdera, about
480 B.C. He wandered up and down Greece, and settled for some time at
Athens. At Athens, however, he was charged with impiety and atheism.
This was on account of a book written by him on the subject of the
gods, which began with the words, "As for the gods, I am unable to say
whether they exist or whether they do not exist." The book was
publicly burnt, and Protagoras had to fly from Athens. He fled to
Sicily, but was drowned on the way about the year 410 B.C.
Protagoras was the author of the famous saying, "Man is the measure of
all things; of what is, that it is; of what is not, that it is not."
Now this saying puts in a nutshell, so to speak, the whole teaching of
Protagoras. And, indeed, it contains in germ the entire thought of the
Sophists. It is well, therefore, that we should fully understand
exactly what it means. The earlier Greek philosophers had made a clear
distinction between sense and thought, between perception and reason,
and had believed that the truth is to be found, not by the senses, but
by reason. The Eleatics had been the first to emphasize this
distinction. The ultimate reality of {113} things, they said, is pure
Being, which is known only through reason; it is the senses which
delude us with a show of becoming. Heracleitus had likewise affirmed
that the truth, which was, for him, the law of becoming, is known by
thought, and that it is the senses which delude us with a show of
permanence. Even Democritus believed that true being, that is,
material atoms, are so small that the senses cannot perceive them, and
only reason is aware of their existence. Now the teaching of
Protagoras really rests fundamentally upon the denying and confusing
of this distinction. If we are to see this, we must first of all
understand that reason is the universal, sensation the particular,
element in man. In the first place, reason is communicable, sensation
incommunicable. My sensations and feelings are personal to myself, and
cannot be imparted to other people. For example, no one can
communicate the sensation of redness to a colour-blind man, who has
not already experienced it. But a thought, or rational idea, can be
communicated to any rational being. Now suppose the question is
whether the angles at the base of an isosceles triangle are equal. We
may approach the problem in two ways. We may appeal either to the
senses or to reason. If we appeal to the senses, one man will come
forward and say that to him the angles look equal. Another man will
say that one angle looks bigger than the other, and so on. But if,
like Euclid, we appeal to reason, then it can be proved that the two
angles are equal, and there is no room left for mere personal
impressions, because reason is a law universally valid and binding
upon all men. My sensations are private and peculiar to myself. They
bind no one but myself. My {114} impressions about the triangle are
not a law to anyone except myself. But my reason I share with all
other rational beings. It is not a law for me merely, but for all. It
is one and the same reason in me and in other men. Reason, therefore,
is the universal, sensation the particular, element in man. Now it is
practically this distinction that Protagoras denied. Man, he said, is
the measure of all things. By man he did not mean mankind at large. He
meant the individual man. And by measure of all things he meant the
standard of the truth of all things. Each individual man is the
standard of what is true to himself. There is no truth except the
sensations and impressions of each man. What seems true to me is true
for me. What seems true to you is true for you.
We commonly distinguish between subjective impressions and objective
truth. The words subjective and objective are constantly recurring
throughout the history of philosophy, and as this is the first time I
use them, I will explain them here. In every act of thought there must
necessarily be two terms. I am now looking at this desk and thinking
of this desk. There is the "I" which thinks, and there is the desk
which is thought. "I" am the subject of the thought, the desk is the
object of the thought. In general, the subject is that which thinks,
and the object is that which is thought. Subjective is that which
appertains to the subject, and objective is that which appertains to
the object. So the meaning of the distinction between subjective
impressions and the objective truth is clear. My personal impression
may be that the earth is flat, but the objective truth is that the
{115} earth is round. Travelling through a desert, I may be subject to
a mirage, and think that there is water in front of me. That is my
subjective impression. The objective truth is that there is nothing
but sand. The objective truth is something which has an existence of
its own, independent of me. It does not matter what I think, or what
you think, what I want, or what you want; the truth is what it is. We
must conform ourselves to the truth. Truth will not conform itself to
our personal inclinations, wishes, or impressions. The teaching of
Protagoras practically amounted to a denial of this. What it meant was
that there is no objective truth, no truth independent of the
individual subject. Whatever seems to the individual true is true for
that individual. Thus truth is identified with subjective sensations
and impressions.
To deny the distinction between objective truth and subjective
impression is the same as to deny the distinction between reason and
sense. To my senses the earth seems flat. It looks flat to the eye. It
is only through reason that I know the objective truth that the world
is round. Reason, therefore, is the only possible standard of
objective truth. If you deny the rational element its proper part, it
follows that you will be left a helpless prey to diverse personal
impressions. The impressions yielded by the senses differ in different
people. One man sees a thing in one way, another sees it in another.
If, therefore, what seems to me true is true for me, and what seems to
you true is true for you, and if our impressions differ, it will
follow that two contradictory propositions must both be true.
Protagoras clearly understood this, {116} and did not flinch from the
conclusion. He taught that all opinions are true, that error is
impossible, and that, whatever proposition is put forward, it is
always possible to oppose to it a contradictory proposition with
equally good arguments and with equal truth. In reality, the result of
this procedure is to rob the distinction between truth and falsehood
of all meaning. It makes no difference whether we say that all
opinions are true, or whether we say that all are false. The words
truth and falsehood, in such context, have no meaning. To say that
whatever I feel is the truth for me means only that what I feel I
feel. To call this "truth for me," adds nothing to the meaning.
Protagoras seems to have been led to these doctrines partly by
observing the different accounts of the same object which the
sense-organs yield to different people, and even to the same person at
different times. If knowledge depends upon these impressions, the
truth about the object cannot be ascertained. He was also influenced
by the teaching of Heracleitus. Heracleitus had taught that all
permanence is illusion. Everything is a perpetual becoming; all things
flow. What is at this moment, at the next moment is not. Even at one
and the same moment, Heracleitus believed, a thing is and is not. If
it is true to say that it is, it is equally true that it is not. And
this is, in effect, the teaching of Protagoras.
The Protagorean philosophy thus amounts to a declaration that
knowledge is impossible. If there is no objective truth, there cannot
be any knowledge of it. The impossibility of knowledge is also the
standpoint of Gorgias. The title of his book is characteristic of
{117} the Sophistical love of paradox. It was called "On Nature, or
the non-existent." In this book he attempted to prove three
propositions, (1) that nothing exists: (2) that if anything exists, it
cannot be known: (3) that if it can be known, the knowledge of it
cannot be communicated.
For proof of the first proposition, "nothing exists," Gorgias attached
himself to the school of the Eleatics, especially to Zeno. Zeno had
taught that in all multiplicity and motion, that is to say, in all
existence, there are irreconcilable contradictions. Zeno was in no
sense a sceptic. He did not seek for contradictions in things for the
sake of the contradictions, but in order to support the positive
thesis of Parmenides, that only being is, and that becoming is not at
all. Zeno, therefore, is to be regarded as a constructive, and not
merely as a destructive, thinker. But it is obvious that by
emphasizing only the negative element in his philosophy, it is
possible to use his antinomies as powerful weapons in the cause of
scepticism and nihilism. And it was in this way that Gorgias made use
of the dialectic of Zeno. Since all existence is self-contradictory,
it follows that nothing exists. He also made use of the famous
argument of Parmenides regarding the origin of being. If anything is,
said Gorgias, it must have had a beginning. Its being must have arisen
either from being, or from not-being. If it arose from being, there is
no beginning. If it arose from not-being, this is impossible, since
something cannot arise out of nothing. Therefore nothing exists.
The second proposition of Gorgias, that if anything exists it cannot
be known, is part and parcel of the whole Sophistic tendency of
thought, which identifies knowledge {118} with sense-perception, and
ignores the rational element. Since sense-impressions differ in
different people, and even in the same person, the object as it is in
itself cannot be known. The third proposition follows from the same
identification of knowledge with sensation, since sensation is what
cannot be communicated.
The later Sophists went much further than Protagoras and Gorgias. It
was their work to apply the teaching of Protagoras to the spheres of
politics and morals. If there is no objective truth, and if what seems
true to each individual is for him the truth, so also, there can be no
objective moral code, and what seems right to each man is right for
him. If we are to have anything worth calling morality, it is clear
that it must be a law for all, and not merely a law for some. It must
be valid for, and binding upon, all men. It must, therefore, be
founded upon that which is universal in man, that is to say, his
reason. To found it upon sense-impressions and feelings is to found it
upon shifting quicksands. My feelings and sensations are binding upon
no man but myself, and therefore a universally valid law cannot be
founded upon them. Yet the Sophists identified morality with the
feelings of the individual. Whatever I think right is right for me.
Whatever you think right is right for you. Whatever each man, in his
irrational self-will, chooses to do, that is, for him, legitimate.
These conclusions were drawn by Polus, Thrasymachus, and Critias.
Now if there is, in this way, no such thing as objective right, it
follows that the laws of the State can be founded upon nothing except
force, custom, and convention. We often speak of just laws, and good
laws. But to speak in that way involves the existence of an objective
{119} standard of goodness and justice, with which we can compare the
law, and see whether it agrees with that standard or not. To the
Sophists, who denied any such standard, it was mere nonsense to speak
of just and good laws. No law is in itself good or just, because there
is no such thing as goodness or justice. Or if they used such a word
as justice, they defined it as meaning the right of the stronger; or
the right of the majority. Polus and Thrasymachus, consequently, drew
the conclusion that the laws of the State were inventions of the weak,
who were cunning enough, by means of this stratagem, to control the
strong, and rob them of the natural fruits of their strength. The law
of force is the only law which nature recognizes. If a man, therefore,
is powerful enough to defy the law with impunity, he has a perfect
right to do so. The Sophists were thus the first, but not the last, to
preach the doctrine that might is right. And, in similar vein, Critias
explained popular belief in the gods as the invention of some crafty
statesman for controlling the mob through fear.
Now it is obvious that the whole tendency of this sophistical teaching
is destructive and anti-social. It is destructive of religion, of
morality, of the foundations of the State, and of all established
institutions. And we can now see that the doctrines of the Sophists
were, in fact, simply the crystallization into abstract thought of the
practical tendencies of the age. The people in practice, the Sophists
in theory, decried and trod under foot the restrictions of law,
authority, and custom, leaving nothing but the deification of the
individual in his crude self-will and egotism. It was in fact an age
of "aufklärung," which means enlightenment or {120} illumination. Such
periods of illumination, it seems, recur periodically in the history
of thought, and in the history of civilization. This is the first, but
not the last, such period with which the history of philosophy deals.
This is the Greek illumination. Such periods present certain
characteristic features. They follow, as a rule, upon an era of
constructive thought. In the present instance the Greek illumination
followed closely upon the heels of the great development of science
and philosophy from Thales to Anaxagoras. In such a constructive
period the great thinkers bring to birth new principles, which, in the
course of time, filter down to the masses of the people and cause
popular, if shallow, science, and a wide-spread culture. Popular
education becomes a feature of the time. The new ideas, fermenting
among the people, break up old prejudices and established ideas, and
thus thought, at first constructive, becomes, among the masses,
destructive in character. Hence the popular thought, in a period of
enlightenment, issues in denial, scepticism, and disbelief. It is
merely negative in its activities and results. Authority, tradition,
and custom are wholly or partially destroyed. And since authority,
tradition, and custom are the cement of the social structure, there
results a general dissolution of that structure into its component
individuals. All emphasis is now laid on the individual. Thought
becomes egocentric. Individualism is the dominant note. Extreme
subjectivity is the principle of the age. All these features make
their appearance in the Greek aufklärung. The Sophistical doctrine
that the truth is what I think, the good what I choose to do, is the
extreme application of the subjective and egocentric principles.
{121}
The early eighteenth century in England and France was likewise a
period of enlightenment, and the era from which we are now, perhaps,
just emerging, bears many of the characteristics of aufklärung. It is
sceptical and destructive. All established institutions, marriage, the
family, the state, the law, come in for much destructive criticism. It
followed immediately upon the close of a great period of constructive
thought, the scientific development of the nineteenth century. And
lastly, the age has produced its own Protagorean philosophy, which it
calls pragmatism. If pragmatism is not egocentric, it is at least
anthropocentric. Truth is no longer thought of as an objective
reality, to which mankind must conform. On the contrary, the truth
must conform itself to mankind. Whatever it is useful to believe,
whatever belief "works" in practice, is declared to be true. But since
what "works" in one age and country does not "work" in another, since
what it is useful to believe to-day will be useless to-morrow, it
follows that there is no objective truth independent of mankind at
all. Truth is not now defined as dependent on the sensations of man,
as it was with Protagoras, but as dependent on the volition of man. In
either case it is not the universal in man, his reason, which is made
the basis of truth and morals, but the subjective, individual,
particular element in him.
We must not forget the many merits of the Sophists. Individually, they
were often estimable men. Nothing is known against the character of
Protagoras, and Prodicus was proverbial for his wisdom and the genuine
probity and uprightness of his principles. Moreover the Sophists
contributed much to the advance of learning. {122} They were the first
to direct attention to the study of words, sentences, style, prosody,
and rhythm. They were the founders of the science of rhetoric. They
spread education and culture far and wide in Greece, they gave a great
impulse to the study of ethical ideas, which made possible the
teaching of Socrates, and they stirred up a ferment of ideas without
which the great period of Plato and Aristotle could never have seen
the light. But, from the philosophical point of view, their merit is
for the first time to have brought into general recognition _the right
of the subject_. For there is, after all, much reason in these attacks
made by the Sophists upon authority, upon established things, upon
tradition, custom and dogma. Man, as a rational being, ought not to be
tyrannized over by authority, dogma, and tradition. He cannot be
subjected, thus violently, to the imposition of beliefs from an
external source. No man has the right to say to me, "you _shall_ think
this," or "you _shall_ think that." I, as a rational being, have the
right to use my reason, and judge for myself. If a man would convince
me, he must not appeal to force, but to reason. In doing so, he is not
imposing his opinions externally upon me; he is educing his opinions
from the internal sources of my own thought; he is showing me that his
opinions are in reality my own opinions, if I only knew it. But the
mistake of the Sophists was that, in thus recognizing the right of the
subject, they wholly ignored and forgot _the right of the object_. For
the truth has objective existence, and is what it is, whether I think
it or not. Their mistake was that though they rightly saw that for
truth and morality to be valid for me, they must be assented to by,
and developed out of, {123} me myself, not imposed from the outside,
yet they laid the emphasis on my merely accidental and particular
characteristics, my impulses, feelings, and sensations, and made these
the source of truth and morality, instead of emphasizing as the source
of truth and right the universal part of me, my reason. "Man is the
measure of all things"; certainly, but man as a rational being, not
man as a bundle of particular sensations, subjective impressions,
impulses, irrational prejudices, self-will, mere eccentricities,
oddities, foibles, and fancies.
Good examples of the right and wrong principles of the Sophists are to
be found in modern Protestantism and modern democracy. Protestantism,
it is often said, is founded upon the right of private judgment, and
this is simply the right of the subject, the right of the individual
to exercise his own reason. But if this is interpreted to mean that
each individual is entitled to set up his mere whims and fancies as
the law in religious matters, then we have the bad sort of
Protestantism. Again, democracy is simply political protestantism, and
democratic ideas are the direct offspring of the protestant
Reformation. The democratic principle is that no rational being can be
asked to obey a law to which his own reason has not assented. But the
law must be founded upon reason, upon the universal in man. I, as an
individual, as a mere ego, have no rights whatever. It is only as a
rational being, as a potentially universal being, as a member of the
commonwealth of reason, that I have any rights, that I can claim to
legislate for myself and others. But if each individual's capricious
self-will, his mere whims and fancies, are erected into a law, then
democracy turns into anarchism and bolshevism.
{124}
It is a great mistake to suppose that the doctrines of the Sophists
are merely antiquated ideas, dead and fossilized thoughts, of interest
only to historians, but of no importance to us. On the contrary,
modern popular thought positively reeks with the ideas and tendencies
of the Sophists. It is often said that a man ought to have strong
convictions, and some people even go so far as to say that it does not
much matter what a man believes, so long as what he believes he
believes strongly and firmly. Now certainly it is quite true that a
man with strong convictions is more interesting than a man without any
opinions. The former is at least a force in the world, while the
latter is colourless and ineffectual. But to put exclusive emphasis on
the mere fact of having convictions is wrong. After all, the final
test of worth must be whether the man's convictions are true or false.
There must be an objective standard of truth, and to forget this, to
talk of the mere fact of having strong opinions as in itself a merit,
is to fall into the error of the Sophists.
Another common saying is that everyone has a right to his own
opinions. This is quite true, and it merely expresses the right of the
subject to use his own reason. But it is sometimes interpreted in a
different way. If a man holds a totally irrational opinion, and if
every weapon is beaten out of his hands, if he is driven from every
position he takes up--so that there is nothing left for him to do,
except to admit that he is wrong, such a man will sometimes take
refuge in the saying, that, after all, argue as you may, he has a
right to his own opinion. But we cannot allow the claim. No man has a
right to wrong opinions. There cannot be any right {125} in wrong
opinions. You have no right to an opinion unless it is founded upon
that which is universal in man, his reason. You cannot claim this
right on behalf of your subjective impressions, and irrational whims.
To do so is to make the mistake of the Sophists.
The tendencies of the more shallow type of modern rationalism exhibit
a similar Sophistical thought. It is pointed out that moral ideas vary
very much in different countries and ages, that in Japan, for example,
prostitution is condoned, and that in ancient Egypt incest was not
condemned. Now it is important to know these facts. They should serve
as a warning to us against dogmatic narrow-mindedness in moral
matters. But some people draw from these facts the conclusion that
there is no universally valid and objectively real moral law. The
conclusion does not follow from the premises, and the conclusion is
false. People's opinions differ, not only on moral questions, but upon
every subject under the sun. Because men, a few hundred years ago,
believed that the earth was flat, whereas now we believe it is round,
it does not follow that it has in reality no shape at all, that there
is no objective truth in the matter. And because men's opinions
differ, in different ages and countries, as to what the true moral law
is, it does not follow that there is no objective moral law.
We will take as our last example the current talk about the importance
of developing one's personality. A man, it is said, should "be
himself," and the expression of his own individuality must be his
leading idea. Now certainly it is good to be oneself in the sense that
it is hypocritical to pretend to be what one is not. Moreover, it is
no doubt true that each man has certain special {126} gifts, which he
ought to develop, so that all, in their diverse ways, may contribute
as much as possible to the spiritual and material wealth of the world.
But this ideal of individuality often leads to false developments, as
we see in the spheres of art and of education. Such a man as Oscar
Wilde, whose personality is essentially evil, defends his artistic
principles on the ground that he must needs express his personality,
that art is nothing but such personal expression, and that it is
subject to no standard save the individuality of the artist. Some
writers on education, among them Mr. Bernard Shaw, who has many points
in common with the Sophists, tell us that to attempt to mould the
character of a child by discipline, is to sin against its personality,
and that the child should be allowed to develop its individuality
unchecked in its own way. But against this we have to protest that to
make the cultivation of individuality an end in itself, and to put
exclusive emphasis on this, is wrong. The cultivation of an
individuality is not in itself a good thing; it is not a good thing if
the individuality be a worthless one. If a child exhibits savage or
selfish tendencies, it must be subjected to discipline, and it is
ridiculous to make a fetish of its personality to such an extent as to
allow it to develop as it likes. In a similar way, the ideal of
individuality is often interpreted to mean that the cultivation of the
mere eccentricities and oddities of the individual is something good.
But the personal peculiarities of a man are just what is worthless
about him. That alone which entitles him to the sacred rights of a
"person" is his rational and universal nature.
{127}
CHAPTER X
SOCRATES
Amid the destruction of all ideals of truth and morality, which was
brought about by the Sophists, there appeared in Athens the figure of
Socrates, who was destined to restore order out of chaos, and to
introduce sanity into the disordered intellectual life of the time.
Socrates was born about 470 B.C. in Athens. His father was a sculptor,
his mother a midwife. Very little is known of his early years and
education, except that he took up his father's occupation as a
sculptor. In later years some statues used to be shown at the
Acropolis in Athens, which were said to be the work of Socrates. But
comparatively early in life he deserted his profession in order to
devote himself to what he considered his mission in life, philosophy.
He spent his entire life in Athens, never departing from it, save for
short periods on three occasions, when he served in military
expeditions in the Athenian army. For from twenty to thirty years he
laboured at his philosophical mission in Athens, until, in his
seventieth year, he was charged with denying the national gods,
introducing new gods of his own, and corrupting the Athenian youth. On
these charges he was condemned to death and executed.
{128}
The personal appearance of Socrates was grotesque. He was short,
thick-set, and ugly. As he grew older he became bald; his nose was
broad, flat, and turned up; he walked with a peculiar gait, and had a
trick of rolling his eyes. His clothes were old and poor. He cared
little or nothing for external appearances.
Socrates believed that he was guided in all his actions by a
supernatural voice, which he called his "daemon." This voice, he
thought, gave him premonitions of the good or evil consequences of his
proposed actions, and nothing would induce him to disobey its
injunctions. Socrates constructed no philosophy, that is to say, no
system of philosophy. He was the author of philosophical tendencies,
and of a philosophic method. He never committed his opinions to
writing. His method of philosophizing was purely conversational. It
was his habit to go down every day to the market place in Athens, or
to any other spot where people gathered, and there to engage in
conversation with anyone who was ready to talk to him about the deep
problems of life and death. Rich or poor, young or old, friend or
stranger, whoever came, and would attend, could listen freely to the
talk of Socrates. He took no fees, as the Sophists did, and remained
always a poor man. He did not, like the Sophists, deliver long
speeches, tirades, and monologues. He never monopolised the
conversation, and frequently it was the other party who did most of
the talking, Socrates only interposing questions and comments, and yet
remaining always master of the conversation, and directing it into
fruitful channels. The conversation proceeded chiefly by the method of
question and answer, Socrates by acute questions educing, bringing to
birth, {129} the thoughts of his partner, correcting, refuting, or
developing them.
In carrying on this daily work, Socrates undoubtedly regarded himself
as engaged upon a mission in some way supernaturally imposed upon him
by God. Of the origin of this mission we have an account in the
"Apology" of Plato, who puts into the mouth of Socrates the following
words:--"Chairephon .... made a pilgrimage to Delphi and had the
audacity to ask this question from the oracle .... He actually asked
if there was any man wiser than I. And the priestess answered, No ....
When I heard the answer, I asked myself: What can the god mean? what
can he be hinting? For certainly I have never thought myself wise in
anything, great or small. What can he mean then, when he asserts that
I am the wisest of men? He cannot lie, of course: that would be
impossible for him. And for a long while I was at a loss to think what
he could mean. At last, after much thought, I started on some such
course as this. I betook myself to one of the men who seemed wise,
thinking that there, if anywhere, I should refute the utterance, and
could say to the oracle: 'This man is wiser than I, and you said I was
the wisest.' Now when I looked into the man--there is no need to give
his name--it was one of our citizens, men of Athens, with whom I had
an experience of this kind--when we talked together I thought, 'This
man seems wise to many men, and above all to himself, but he is not
so'; and then I tried to show that he thought he was wise, but he was
not. Then he got angry with me and so did many who heard us, but I
went away and thought to myself, 'Well, at any rate I am wiser than
this man: probably neither of {130} us knows anything of beauty or of
good, but he thinks he knows something when he knows nothing, and I,
if I know nothing, at least never suppose that I do. So it looks as
though I really were a little wiser than he, just in so far as I do
not imagine myself to know things about which I know nothing at all.'
After that I went to another man who seemed to be wiser still, and I
had exactly the same experience, and then he got angry with me too,
and so did many more. Thus I went round them all, one after the other,
aware of what was happening and sorry for it, and afraid that they
were getting to hate me."
In this passage we can see, too, the supposed origin of another
peculiar Socratic feature, the Socratic "irony." In any discussion,
Socrates would, as a rule, profess himself to be totally ignorant of
the matter in hand, and only anxious to learn the wisdom possessed by
his interlocutor. This professed ignorance was not affectation. He was
genuinely impressed with the notion that not only he, but all other
men, live for the most part in ignorance of the things that are the
most important to be known, the nature of goodness, beauty, and truth.
He believed that the self-styled knowledge of the wise was, for the
most part, nothing but pretentious ignorance. Nevertheless, he used
this profession of ignorance as a weapon of offence, and it became in
his hands a powerful rhetorical instrument, which he used with
specially telling effect against those who, puffed up with their own
importance and wisdom, pretended to knowledge which they did not
possess. Such hollow pretence of knowledge met with uncompromising
exposure at the hands of Socrates. With such persons he would open the
{131} conversation with a confession of his own ignorance and an
expression of his desire to learn the wisdom, which, he knew, they
possessed. In their eagerness to show off their knowledge, they would,
perhaps, rush into the breach with some very positive assertion.
Socrates would express himself as delighted with this, but would add
that there were one or two things about it which he did not fully
understand, and he would proceed, with a few dexterous questions, to
expose the hollowness, the shallowness, or the ignorance of the
answers.
It was chiefly the young men of Athens who gathered round Socrates,
who was for them a centre of intellectual activity and a fountain of
inspiration. It was this fact which afterwards formed the basis of the
charge that he "corrupted the youth." He was a man of the noblest
character and of the simplest life. Accepting no fees, he acquired no
wealth. Poor, caring nothing for worldly goods, wholly independent of
the ordinary needs and desires of men, he devoted himself exclusively
to the acquisition of that which, in his eyes, alone had value, wisdom
and virtue. He was endowed with the utmost powers of physical
endurance and moral strength. When he served with the army in the
Peloponnesian war, he astonished his fellow-soldiers by his bravery,
and his cheerful endurance of every hardship. On two occasions, at
considerable risk to himself, he saved the lives of his companions. At
the battle of Delium it is said that Socrates was the only man who
kept his head in the rout of the Athenians. He was an excellent
companion, and though simple in his habits, and independent of all
material pleasures, never made a fetish of this independence, nor
allowed it to degenerate into a harsh asceticism, {132} Thus, he
needed no wine, but yet, if occasion called for it, he not only drank,
but could drink more than any other man without turning a hair. In the
"Banquet" of Plato, Socrates is depicted sitting all night long
drinking and talking philosophy with his friends. One by one the
guests succumbed, leaving only Socrates and two others, and at last,
as the dawn broke, these two also fell asleep. But Socrates got up,
washed himself, and went down to the market place to begin his daily
work.
In his seventieth year he was tried on three charges: (1) for denying
the national gods, (2) for setting up new gods of his own, (3) for
corrupting the youth. All these charges were entirely baseless. The
first might well have been brought against almost any of the earlier
Greek thinkers with some justice. Most of them disbelieved in the
national religion; many of them openly denied the existence of the
gods. Socrates, almost alone, had refrained from any such attitude. On
the contrary, he always enjoined veneration towards the gods, and
urged his hearers, in whatever city they might be, to honour the gods
according to the custom of that city. According to Xenophon, however,
he distinguished between the many gods and the one creator of the
universe, who controls, guides, and guards over the lives of men. The
second charge appears to have been based upon the claim of Socrates to
be guided by a supernatural inner voice, but whatever we may think of
this claim, it can hardly constitute good ground for a charge of
introducing new gods. The third charge, that of corrupting the youth,
was equally baseless, though the fact that Alcibiades, who had been a
favourite pupil of Socrates, afterwards turned traitor to Athens, and
{133} led, moreover, a dissolute and unprincipled life, no doubt
prejudiced the philosopher in the eyes of the Athenians. But Socrates
was not responsible for the misdeeds of Alcibiades, and his general
influence upon the Athenian youth was the very opposite of corrupting.
What then were the real reasons for these accusations? In the first
place, there is no doubt that Socrates had made many personal enemies.
In his daily disputations he had not spared even the most powerful men
in Athens, but had ruthlessly laid bare the ignorance of those who
pretended to be wise. There is, however, no reason to believe that the
three men who actually laid the charges, Melitus, Lycon, and Anytus,
did so out of any personal animosity. But they were men of straw, put
forward by more powerful persons who remained behind the scenes. In
the second place, Socrates had rendered himself obnoxious to the
Athenian democracy. He was no aristocrat in feeling, nor was he a
supporter of the vested interests and privileges of the few. But he
could not accommodate himself to the mob-rule which then went by the
name of democracy. The government of the State, he believed, should be
in the hands of the wise, the just, and the good, those competent and
trained to govern, and these are necessarily the few. He himself had
taken no part in the political life of the time, preferring to guide
by his influence and advice the young men on whom some day the duties
of the State would devolve. On two occasions only did he take an
active part in politics, and on both occasions his conduct gave great
offence. Both these incidents are recounted in a passage in Plato's
"Apology," which I will quote. The {134} first incident refers to the
aftermath of the battle of Arginusae. The Athenian fleet had gained a
victory here, but lost twenty-five ships of war, and the whole of the
crews of these ships were drowned. This was attributed to the
carelessness of the generals, and there was great indignation in
Athens, upon their return whither the generals were put upon their
trial. According to the law of Athens each accused had to be given a
separate trial, but in their eagerness to have the generals condemned,
the judges in this instance decided to try them all in a body. "You
know, men of Athens," says Socrates in the "Apology," "that I have
never held any other office in the State, but I did serve on the
Council. And it happened that my tribe, Antiochis, had the Presidency
at the time you decided to try the ten generals who had not taken up
the dead after the fight at sea. You decided to try them in one body,
contrary to law, as you all felt afterwards. On that occasion I was
the only one of the Presidents who opposed you, and told you not to
break the law; and I gave my vote against you; and when the orators
were ready to impeach and arrest me, and you encouraged them and
hooted me, I thought then that I ought to take all the risks on the
side of law and justice, rather than side with you, when your
decisions were unjust, through fear of imprisonment or death. That was
while the city was still under the democracy. When the oligarchy came
into power, the Thirty, in their turn, summoned me with four others to
the Rotunda, and commanded us to fetch Leon of Salamis from that
island, in order to put him to death: the sort of commands they often
gave to many others, anxious as they were to incriminate all they
could. And on that occasion {135} I showed not by words only, that for
death, to put it bluntly, I did not care one straw--but I did care,
and to the full, about doing what was wicked and unjust. I was not
terrified then into doing wrong by that government in all its power;
when we left the Rotunda, the other four went off to Salamis and
brought Leon back, but I went home. And probably I should have been
put to death for it, if the government had not been overthrown soon
afterwards."
But there was a third, and greater reason, for the condemnation of
Socrates. These charges were brought against him because the popular
mind confused him with the Sophists. This was entirely absurd, because
Socrates in no respect resembled the Sophists, either in the manner of
his life or in the tendency of his thought, which was wholly
anti-sophistical. But that such a confusion did exist in the popular
mind is clearly proved by "The Clouds" of Aristophanes. Aristophanes
was a reactionary in thought and politics, and, hating the Sophists as
the representatives of modernism, he lampooned them in his comedy,
"The Clouds." Socrates appears in the play as the central character,
and the chief of the Sophists. This was entirely unjust, but it
affords evidence of the fact that Socrates was commonly mistaken for a
Sophist by the Athenians. Aristophanes would not have ventured to
introduce such a delusion into his play, had his audience not shared
in it. Now at this time a wave of reaction was passing over Athens,
and there was great indignation against the Sophists, who were rightly
supposed to be overturning all ideals of truth and goodness. Socrates
fell a victim to the anger of the populace against the Sophists.
{136}
At the trial Socrates conducted himself with dignity and confidence.
It was usual in those days for an accused person to weep and lament,
to flatter the judges, to seek indulgence by grovelling and fawning,
to appeal for pity by parading his wife and children in the court.
Socrates refused to do any of these things, considering them unmanly.
His "defence" was, indeed, not so much a defence of himself as an
arraignment of his judges, the people of Athens, for their corruption
and vice. This attitude of Socrates certainly brought about his
condemnation. There is every reason to believe that if he had adopted
a grovelling, even a conciliatory tone, he would have been acquitted.
As it was, he was found guilty by a bare majority. The law enacted
that, when the charge was proved, those who had brought the accusation
should first propose the penalty which they thought fitting; then the
accused himself should propose an alternative penalty. It was for the
judges to decide which of the two should be inflicted. The accusers of
Socrates proposed the death-penalty. Here again Socrates might have
escaped by proposing at once some petty punishment. This would have
satisfied the people, who were only anxious to score off the
troublesome philosopher and pedant. But Socrates proudly affirmed
that, as he was guilty of no crime, he deserved no punishment. To
propose a penalty would be to admit his guilt. Far from being a guilty
person, he considered himself in the light of a public benefactor, and
as such, if he were to get his deserts, he proposed that he should be
publicly honoured by being given a seat at the President's table.
Nevertheless, as the law forced him to propose a penalty, he would,
without prejudice to his {137} plea of innocence, suggest a fine of
thirty minas. This conduct so exasperated the judges that he was now
condemned to death by a large majority, about eighty of those who had
previously voted for his acquittal now voting for his execution.
Thirty days elapsed before he was executed, and these days were spent
in prison. His friends, who had free access to him, urged him to
escape. These things were possible in Athens. Anaxagoras had
apparently escaped with the help of Pericles. A little silver in the
hands of the jailguards would probably have settled the matter.
Socrates could fly to Thessaly, where the law could not reach him, as
Anaxagoras had fled to Ionia. But Socrates steadily refused, saying
that to flee from death was cowardly, and that one ought to obey the
laws. The law had decreed his death, and he must obey. After thirty
days, therefore, the poison cup was brought to him, and he drank it
without flinching. Here is Plato's account of the death of Socrates,
which I quote from the "Phaedo." In detail it cannot be considered
historical, but we may well believe that the main incidents as well as
the picture it gives us of the bearing and demeanour of the
philosopher in his last moments, are accurate representations of the
facts.
"He rose and went into a chamber to bathe, and Crito followed him, but
he directed us to wait for him. We waited, therefore, conversing among
ourselves about what had been said, and considering it again, and
sometimes speaking about our calamity, how severe it would be to us,
sincerely thinking that, like those who are deprived of a father, we
should pass the rest of our lives as orphans. When he had bathed and
his {138} children were brought to him, for he had two little sons and
one grown up, and the women belonging to his family were come, having
conversed with them in the presence of Crito, and given them such
injunctions as he wished, he directed the women and children to go
away, and then returned to us. And it was now near sunset; for he
spent a considerable time within. But when he came from bathing he sat
down and did not speak much afterwards: then the officer of the Eleven
came in and standing near him said, 'Socrates, I shall not have to
find that fault with you that I do with the others, that they are
angry with me, and curse me, when, by order of the archons, I bid them
drink the poison. But you, on all other occasions during the time you
have been here, I have found to be the most noble, meek and excellent
man of all that ever came into this place; and, therefore, I am now
well convinced that you will not be angry with me. Now, then, for you
know what I came to announce to you, farewell, and endeavour to bear
what is inevitable as easily as possible.' And at the same time,
bursting into tears, he turned away and withdrew. And Socrates,
looking after him, said, 'And thou too, farewell, we will do as you
direct.' At the same time, turning to us he said 'How courteous the
man is; during the whole time I have been here he has visited me, and
conversed with me sometimes, and proved the worthiest of men; and how
generously he weeps for me. But come, Crito, let us obey him and let
some one bring the poison, if it is ready pounded, but if not let the
man pound it.'
"Then Crito said, 'But I think, Socrates, that the sun is still on the
mountains, and has not yet set. Besides, {139} I know that others have
drunk the poison very late, after it had been announced to them, and
have supped and drunk freely, and some even have enjoyed the objects
of their love. Do not hasten them, for there is yet time.'
"Upon this Socrates replied, 'These men whom you mention, Crito, do
these things with good reason, for they think they shall gain by so
doing, and I too with good reason, shall not do so; for I think I
shall gain nothing by drinking a little later, except to become
ridiculous to myself, in being so fond of life, and sparing of it when
none any longer remains. Go then,' he said, 'obey, and do not resist.'
"Crito having heard this, nodded to the boy that stood near. And the
boy having gone out, and stayed for some time, came, bringing with him
the man that was to administer the poison, who brought it ready
pounded in a cup. And Socrates, on seeing the man, said, 'Well, my
good friend, as you are skilled in these matters, what must I do?'
'Nothing else,' he replied, 'than when you have drunk it walk about,
until there is a heaviness in your legs, then lie down; thus it will
do its purpose.' And at the same time he held out the cup to Socrates.
And he having received it very cheerfully, Echecrates, neither
trembling, nor changing at all in colour or countenance, but, as he
was wont, looking steadfastly at the man, said, 'what say you of this
potion, with respect to making a libation to anyone, is it lawful or
not?' 'We only pound so much, Socrates,' he said, 'as we think
sufficient to drink.' 'I understand you,' he said, 'but it is
certainly both lawful and right to pray to the gods that my departure
hence thither may be happy; which therefore I pray, and so {140} may
it be.' And as he said this he drank it off readily and calmly. Thus
far, most of us were with difficulty able to restrain ourselves from
weeping, but when we saw him drinking, and having finished the
draught, we could do so no longer; but in spite of myself the tears
came in full torrent, so that, covering my face, I wept for myself,
for I did not weep for him, but for my own fortune, in being deprived
of such a friend. But Crito, even before me, when he could not
restrain his tears, had risen up. But Apollodorus even before this had
not ceased weeping, and then, bursting into an agony of grief, weeping
and lamenting, he pierced the heart of everyone present, except
Socrates himself. But he said. 'What are you doing, my admirable
friends? I indeed, for this reason chiefly, sent away the women, that
they might not commit any folly of this kind. For I have heard that it
is right to die with good omens. Be quiet, therefore, and bear up.'
"When we heard this we were ashamed, and restrained our tears. But he,
having walked about, when he said that his legs were growing heavy,
lay down on his back; for the man so directed him. And at the same
time he who gave him the poison, taking hold of him, after a short
interval examined his feet and legs; and then having pressed his foot
hard, he asked if he felt it; he said that he did not. And after this
he pressed his thighs; and thus going higher he showed us that he was
growing cold and stiff. Then Socrates touched himself, and said that
when the poison reached his heart he should then depart. But now the
parts around the lower belly were almost cold; when uncovering
himself, for he had been covered over, he said; and they were his
{141} last words. 'Crito, we owe a cock to AEsculapius; pay it,
therefore, and do not neglect it.' 'It shall be done,' said Crito,
'but consider whether you have anything else to say.'
"To this question he gave no reply; but shortly after he gave a
convulsive movement, and the man covered him, and his eyes were fixed,
and Crito, perceiving it, closed his mouth and eyes.
"This, Echecrates, was the end of our friend, a man, as we may say,
the best of all of his time that we have known, and moreover, the most
wise and just."
Our knowledge of the teaching of Socrates is derived chiefly from two
sources, Plato and Xenophon, for the peculiarities of each of whom
allowances must be made. Plato in his dialogues makes Socrates the
mouthpiece of his own teaching, consequently the majority of the
tenets to which Socrates is made to give expression are purely
Platonic doctrines of which the historical Socrates could never even
have dreamed. It might, therefore, seem at first sight that there is
no possibility of ascertaining from Plato's dialogues any trustworthy
account of the ideas of Socrates. But on closer inspection this does
not turn out to be correct, because the earlier dialogues of Plato
were written before he had developed his own philosophy, and when he
was, to all intents and purposes, simply a disciple of Socrates, bent
only upon giving the best expression to the Socratic doctrine. Even in
these Socratic dialogues, however, we have what is no doubt an
idealized portrait of Socrates. Plato makes no pretence of being
merely a biographer or historian. The incidents and conversation,
although they are no doubt frequently founded upon facts, are, in the
{142} main, imaginary. All we can say is that they contain the gist
and substance of the philosophy of Socrates. The other source,
Xenophon, also has his peculiarities. If Plato was an idealizing
philosopher, Xenophon was a prosaic and matter of fact man of affairs.
He was a plain, honest soldier. He had no great insight into any
philosophy, Socratic or otherwise. He was not attached to Socrates
primarily as a philosopher, but as an admirer of his character and
personality. If Plato puts the teaching of Socrates too high, Xenophon
puts it too low. But, in spite of this, Xenophon's Memorabilia
contains a mass of valuable information both about the life and the
philosophical ideas of Socrates.
The Socratic teaching is essentially ethical in character. In this
alone did Socrates bear any resemblance to the Sophists. It was the
Sophists who had introduced into Greek philosophy the problem of man,
and of the duties of man. And to these problems Socrates also turns
his exclusive attention. He brushes aside all questions as to the
origin of the world, or the nature of the ultimate reality, of which
we have heard so much in the philosophies of the earlier thinkers.
Socrates openly deprecated such speculations and considered all such
knowledge comparatively worthless as against ethical knowledge, the
knowledge of man. Mathematics, physics, and astronomy, he thought,
were not valuable forms of knowledge. He said that he never went for
walks outside the city, because there is nothing to be learnt from
fields and trees.
Nevertheless the ethical teaching of Socrates was founded upon a
theory of knowledge, which is quite simple, but extremely important.
The Sophists had founded knowledge upon perception, with the result
{143} that all objective standards of truth had been destroyed. It was
the work of Socrates to found knowledge upon reason, and thereby to
restore to truth its objectivity. Briefly, the theory of Socrates may
be summarized by saying that he taught that _all knowledge is knowledge
through concepts_. What is a concept? When we are directly conscious of
the presence of any particular thing, a man, a tree, a house, or a
star, such consciousness is called perception. When, shutting our
eyes, we frame a mental picture of such an object, such consciousness
is called an image or representation. Such mental images are, like
perceptions, always ideas of particular individual objects. But
besides these ideas of individual objects, whether through
sense-perception or imagination, we have also general ideas, that is
to say, not ideas of any particular thing, but ideas of whole classes
of things. If I say "Socrates is mortal," I am thinking of the
individual, Socrates. But if I say "Man is mortal," I am thinking, not
of any particular man, but of the class of men in general. Such an
idea is called a general idea, or a concept. All class-names, such as
man, tree, house, river, animal, horse, being, which stand, not for
one thing, but for a multitude of things, represent concepts. We form
these general ideas by including in them all the qualities which the
whole class of objects has in common, and excluding from them all the
qualities in which they differ, that is to say, the qualities which
some of the objects possess, but others do not. For example, I cannot
include the quality whiteness in my general idea of horses, because,
though some horses are white, others are not. But I can include the
quality vertebrate because all horses agree in being vertebrate. Thus
a {144} concept is formed by bringing together the ideas in which all
the members of a class of objects agree with one another, and
neglecting the ideas in which they differ.
Now reason is the faculty of concepts. This may not, at first sight,
be obvious. Reason, it might be objected, is the faculty of arguing,
of drawing conclusions from premises. But a little consideration will
show us that, though this is so, yet all reasoning is employed upon
concepts. All reasoning is either deductive or inductive. Induction
consists in the formulation of general principles from particular
cases. A general principle is always a statement made, not about a
particular thing, but about a whole class of things, that is, about a
concept. Concepts are formed inductively by comparing numerous
examples of a class. Deductive reasoning is always the opposite
process of applying general principles to particular cases. If we
argue that Socrates must be mortal because all men are so, the
question is whether Socrates is a man, that is to say, whether the
concept, man, is properly applied to the particular object called
Socrates. Thus inductive reasoning is concerned with the formation of
concepts, deductive reasoning with the application of them.
Socrates, in placing all knowledge in concepts, was thus making reason
the organ of knowledge. This was in direct opposition to the principle
of the Sophists, who placed all knowledge in sense-perception. Now
since reason is the universal element in man, it follows that
Socrates, in identifying knowledge with concepts, was restoring the
belief in an objective truth, valid for all men, and binding upon all
men, and was destroying the Sophistic teaching that the truth is
whatever each {145} individual chooses to think it is. We shall see
this more clearly if we reflect that a concept is the same thing as a
definition. If we wish to define any word, for example, the word man,
we must include in our definition only the qualities which all men
have in common. We cannot, for example, define man as a white-skinned
animal, because all men are not white-skinned. Similarly we cannot
include "English-speaking" in our definition, because, though some men
speak English, others do not. But we might include such a quality as
"two-legged," because "two-legged" is a quality common to all human
beings, except mere aberrations and distortions of the normal type.
Thus a definition is formed in the same way as a concept, namely, by
including the common qualities of a class of objects, and excluding
the qualities in which the members of the class differ. A definition,
in fact, is merely the expression of a concept in words. Now by the
process of fixing definitions we obtain objective standards of truth.
If, for example, we fix the definition of a triangle, then we can
compare any geometrical figure with it, and say whether it is a
triangle or not. It is no longer open to anyone to declare that
whatever he chooses to call a triangle is a triangle. Similarly, if we
fix upon a definition of the word man, we can then compare any object
with that definition, and say whether it is a man or not. Again, if we
can decide what the proper concept of virtue is, then the question
whether any particular act is virtuous can only be decided by
comparing that act with the concept, and seeing if they agree. The
Sophist can no longer say, "whatever seems to me right, is right for
me. Whatever I choose to do is virtuous for me." His act must be
judged, not by {146} his subjective impressions, but by the concept or
definition, which is thus an objective standard of truth, independent
of the individual. This, then, was the theory of knowledge propounded
by Socrates. Knowledge, he said, is not the same thing as the
sensations of the individual, which would mean that each individual
can name as the truth whatever he pleases. Knowledge means knowledge
of things as they objectively are, independently of the individual,
and such knowledge is knowledge of the concepts of things. Therefore
the philosophizing of Socrates consisted almost exclusively in trying
to frame proper concepts. He went about enquiring, "What is virtue?"
"What is prudence?" "What is temperance?"--meaning thereby "what are
the true concepts or definitions of these things?" In this way he
attempted to find a basis for believing in an objectively real truth
and an objectively real moral law.
His method of forming concepts was by induction. He would take common
examples of actions which are universally admitted to be prudent, and
would attempt to find the quality which they all have in common, and
by virtue of which they are all classed together, and so form the
concept of prudence. Then he would bring up fresh examples, and see
whether they agreed with the concept so formed. If not, the concept
might have to be corrected in the light of the new examples.
But the Socratic theory of knowledge was not a theory put forward for
its own sake, but for practical ends. Socrates always made theory
subservient to practice. He wanted to know what the concept of virtue
is, only in order to practise virtue in life. And this brings us to
the central point of the ethical teaching of Socrates, {147} which was
the identification of virtue with knowledge. Socrates believed that a
man cannot act rightly, unless he first knows what is right, unless,
in fact, he knows the concept of right. Moral action is thus founded
upon knowledge, and must spring from it. But not only did Socrates
think that if a man has not knowledge, he cannot do right. He also put
forward the much more doubtful assertion that if a man possesses
knowledge, he cannot do wrong. All wrong-doing arises from ignorance.
If a man only knows what is right, he must and will infallibly do what
is right. All men seek the good, but men differ as to what the good
is. "No man," said Socrates, "intentionally does wrong." He does
wrong, because he does not know the true concept of right, and being
ignorant, thinks that what he is doing is good. "If a man intentionally
does wrong," said Socrates again, "he is better than a man who does so
unintentionally." For the former has in him the essential condition of
goodness, knowledge of what goodness is, but the latter, lacking that
knowledge, is hopeless.
Aristotle, in commenting upon this whole doctrine, observed that
Socrates had ignored or forgotten the irrational parts of the soul.
Socrates imagined that everybody's actions are governed solely by
reason, and that therefore if only they reasoned aright, they must do
right. He forgot that the majority of men's actions are governed by
passions and emotions, "the irrational parts of the soul." Aristotle's
criticism of Socrates is unanswerable. All experience shows that men
do deliberately do wrong, that, knowing well what is right, they
nevertheless do wrong. But it is easy to see why Socrates made this
mistake; he was arguing only from {148} his own case. Socrates really
does appear to have been above human weakness. He was not guided by
passions, but by reason, and it followed as the night follows the day,
that if Socrates knew what was right, he did it. He was unable to
understand how men, knowing the right, could yet do the wrong. If they
are vicious, he thought, it must be because they do not know what is
right. The criticism of Aristotle is thus justified. Yet for all that,
the theory of Socrates is not to be too quickly brushed aside. There
is more truth in it than appears at first sight. We say that a man
believes one thing and does another. Yet it is a matter of question
what a man really believes, and what is the test of his belief. Men go
to church every Sunday, and there repeat formulas and prayers, of
which the main idea is that all earthly riches are worthless in
comparison with spiritual treasures. Such men, if asked, might tell us
that they believe this to be true. They believe that they believe it.
And yet in actual life, perhaps, they seek only for earthly riches,
and behave as if they thought these the supreme good. What do such men
really believe? Do they believe as they speak, or as they act? Is it
not at least arguable that they are really pursuing what they believe
to be good, and that, if they were genuinely convinced of the
superiority of spiritual treasures, they would seek them, and not
material riches? This at least is what Socrates thought. All men seek
the good, but the many do not know what the good is. There is
certainly truth in this in many cases, though in others there can be
no doubt that men do deliberately what they know to be evil.
There are two other characteristic Socratic propositions {149} which
flow from the same general idea, that virtue is identical with
knowledge. The first is, that virtue can be taught. We do not
ordinarily think that virtue can be taught like arithmetic. We think
that virtue depends upon a number of factors, prominent among which
are the inborn disposition of a man, heredity, environment, modified
to some extent by education, practice, and habit. The consequence is
that a man's character does not change very much as he grows older. By
constant practice, by continual self-control, a man may, to some
extent, make himself better, but on the whole, what he is he remains.
The leopard, we say, does not change his spots. But as, for Socrates,
the sole condition of virtue is knowledge, and as knowledge is just
what can be imparted by teaching, it followed that virtue must be
teachable. The only difficulty is to find the teacher, to find some
one who knows the concept of virtue. What the concept of virtue
is--that is, thought Socrates, the precious piece of knowledge, which
no philosopher has ever discovered, and which, if it were only
discovered, could at once be imparted by teaching, whereupon men would
at once become virtuous.
The other Socraticism is that "virtue is one." We talk of many
virtues, temperance, prudence, foresight, benevolence, kindness, etc.
Socrates believed that all these particular virtues flowed from the
one source, knowledge. Therefore knowledge itself, that is to say,
wisdom, is the sole virtue, and this includes all the others.
This completes the exposition of the positive teaching of Socrates. It
only remains for us to consider what position Socrates holds in the
history of thought. There are two sides of the Socratic teaching. In
the first {150} place, there is the doctrine of knowledge, that all
knowledge is through concepts. This is the scientific side of the
philosophy of Socrates. Secondly, there is his ethical teaching. Now
the essential and important side of Socrates is undoubtedly the
scientific theory of concepts. It is this which gives him his position
in the history of philosophy. His ethical ideas, suggestive as they
were, were yet all tainted with the fallacy that men are governed only
by reason. Hence they have exercised no great influence on the history
of thought. But the theory of concepts worked a revolution in
philosophy. Upon a development of it is founded the whole of Plato's
philosophy, and, through Plato, the philosophy of Aristotle, and,
indeed, all subsequent idealism. The immediate effect of this theory,
however, was the destruction of the teaching of the Sophists. The
Sophists taught the doctrine that truth is sense-perception, and as
the perceptions of different individuals differ in regard to the same
object, it followed that truth became a matter of taste with the
individual. This undermined all belief in truth as an objective
reality, and, by similar reasoning, faith in the objectivity of the
moral law was also destroyed. The essential position of Socrates is
that of a restorer of faith. His greatness lay in the fact that he saw
that the only way to combat the disastrous results of the Sophistic
teaching was to refute the fundamental assumption from which all that
teaching flowed, the assumption, namely, that knowledge is perception.
Against this, therefore, Socrates opposed the doctrine that knowledge
is through concepts. To base knowledge upon concepts is to base it
upon the universality of reason, and therefore to restore it from the
{151} position of a subjective seeming to that of an objective
reality.
But though Socrates is thus a restorer of faith, we must not imagine
that his thought is therefore a mere retrogression to the intellectual
condition of pre-Sophistic times. It was, on the contrary, an advance
beyond the Sophists. We have here, in fact, an example of what is the
normal development of all thought, whether in the individual or the
race. The movement of thought exhibits three stages. The first stage
is positive belief, not founded upon reason; it is merely conventional
belief. At the second stage thought becomes destructive and sceptical.
It denies what was affirmed in the previous stage. The third stage is
the restoration of positive belief now founded upon the concept, upon
reason, and not merely upon custom. Before the time of the Sophists,
men took it for granted that truth and goodness are objective
realities; nobody specially affirmed it, because nobody denied it. It
seemed obvious. It was, thus, not believed on rational grounds, but
through custom and habit. This, the first stage of thought, we may
call the era of simple faith. When the Sophists came upon the scene,
they brought reason and thought to bear upon what had hitherto been
accepted as a matter of course, namely law, custom, and authority. The
first encroachment of reason upon simple faith is always destructive,
and hence the Sophists undermined all ideals of goodness and truth.
Socrates is the restorer of these ideals, but with him they are no
longer the ideals of simple faith; they are the ideals of reason. They
are based upon reason. Socrates substituted comprehending belief for
unintelligent assent. We may contrast him, in this {152} respect, with
Aristophanes. Aristophanes, the conservative, the believer in the
"good old times," saw, as clearly as Socrates, the disastrous effects
worked by the Sophists upon public morals. But the remedy he proposed
was a violent return to the "good old times." Since it was thought
which worked these ill effects, thought must be suppressed. We must go
back to simple faith. But simple faith, once destroyed by thought,
never returns either to the individual, or to the race. This can no
more happen than a man can again become a child. There is only one
remedy for the ills of thought, and that is, more thought. If thought,
in its first inroads, leads, as it always does, to scepticism and
denial, the only course is, not to suppress thought, but to found
faith upon it. This was the method of Socrates, and it is the method,
too, of all great spirits. They are not frightened of shadows. They
have faith in reason. If reason leads them into the darkness, they do
not scuttle back in fright. They advance till the light comes again.
They are false teachers who counsel us to give no heed to the
promptings of reason, if reason brings doubt into our beliefs. Thought
cannot be thus suppressed. Reason has rights upon us as rational
beings. We cannot go back. We must go on, and make our beliefs
rational. We must found them upon the concept, as Socrates did.
Socrates did not deny the principle of the Sophists that all
institutions, all ideals, all existing and established things must
justify themselves before the tribunal of reason. He accepted this
without question. He took up the challenge of thought, and won the
battle of reason in his day.
The Sophists brought to light the principle of subjectivity, the
principle that the truth must be _my_ truth, {153} and the right _my_
right. They must be the products of my own thinking, not standards
forcibly imposed upon me from without. But the mistake of the Sophists
was to imagine that the truth must be mine, merely in my capacity as a
percipient creature of sense, which means that I have a private truth
of my own. Socrates corrected this by admitting that the truth must be
my truth, but mine in my capacity as a rational being, which means,
since reason is the universal, that it is not my private truth, but
universal truth which is shared by and valid for all rational beings.
Truth is thus established as being not mere subjective appearance, but
objective reality, independent of the sensations, whims, and self-will
of the individual. The whole period of Socrates and the Sophists is
full of instruction. Its essential lesson is that to deny the
supremacy of reason, to set up any other process of consciousness
above reason, must inevitably end in scepticism and the denial of the
objectivity of truth and morality. Many theosophists and others, at
the present day, teach the doctrine of what they call "intuition." The
supreme kind of religious knowledge, they think, is to be reached by
intuition, which is conceived as something higher than reason. But
this is simply to make the mistake of Protagoras over again. It is
true that this so-called intuition is not merely sense-perception, as
was the case with Protagoras. It is, however, a form of immediate
spiritual perception. It is immediate apprehension of the object as
being present to me, as having _thereness_. It is therefore of the
nature of perception. It is spiritual and super-sensuous, as opposed
to material and sensuous, perception. But it makes no difference at
all whether perception is sensuous {154} or super-sensuous. To place
the truth in any sort of perception is, in principle, to do as
Protagoras did, to yield oneself up a helpless prey to the subjective
impressions of the individual. I intuit one thing; another man intuits
the opposite. What I intuit must be true for me, what he intuits true
for him. For we have denied reason, we have placed it below intuition,
and have thereby discarded that which alone can subject the varying
impressions of each individual to the rule of a universal and
objective standard. The logical conclusion is that, since each man's
intuition is true for him, there is no such thing as an objective
truth. Nor can there be such a thing, in these circumstances, as an
objective goodness. Thus the theory must end in total scepticism and
darkness. The fact that theosophists do not, as a matter of fact, draw
these sceptical conclusions, simply means that they are not as
clear-headed and logical as Protagoras was.
{155}
CHAPTER XI
THE SEMI-SOCRATICS
Upon the death of Socrates there ensued a phenomenon which is not
infrequent in the history of thought. A great and many-sided
personality combines in himself many conflicting tendencies and ideas.
Let us take an example, not, however, from the sphere of intellect,
but from the sphere of practical life. We often say that it is
difficult to reconcile mercy and justice. Among the many small
personalities, one man follows only the ideal of mercy, and as his
mercy has not in it the stern stuff of justice, it degenerates into
mawkishness and sentimental humanitarianism. Another man follows only
the ideal of justice, forgetting mercy, and he becomes harsh and
unsympathetic. It takes a greater man, a larger personality,
harmoniously to combine the two. And as it is in the sphere of
practical life, so it is in the arena of thought and philosophy. A
great thinker is not he who seizes upon a single aspect of the truth,
and pushes that to its extreme limit, but the man who combines, in one
many-sided system, all the varying and conflicting sides of truth. By
emphasizing one thought, by being obsessed by a single idea and
pushing it to its logical conclusion, regardless of the other aspects
of the truth, one may indeed achieve a considerable local and {156}
temporary reputation; because such a procedure often leads to striking
paradoxes, to strange and seemingly uncommon conclusions. The
reputations of such men as Nietzsche, Bernard Shaw, Oscar Wilde, are
made chiefly in this way. But upon the death of a great all-embracing
personality, just because his thought is a combination of so many
divergent truths, we often find that it splits up into its component
parts, each of which gives rise to a one-sided school of thought. The
disciples, being smaller men, are not able to grasp the great man's
thought in its wholeness and many-sidedness. Each disciple seizes upon
that portion of his master's teaching which has most in common with
his own temperament, and proceeds to erect this one incomplete idea
into a philosophy, treating the part as if it were the whole. This is
exactly what happened after the death of Socrates. Only one man among
his disciples was able to grasp the whole of his teaching, and
understand the whole of his personality, and that was Plato. Among the
lesser men who were the followers and personal friends of Socrates,
there were three who founded schools of philosophy, each partial and
one-sided, but each claiming to be the exponent of the true
Socraticism. Antisthenes founded the Cynic school, Aristippus the
Cyrenaic, and Euclid the Megaric.
Now, of the two aspects of the Socratic philosophy, the theory of
concepts, and the ethical theory, it is easy for us, looking back upon
history, to see which it was that influenced the history of thought
most, and which, therefore, was the most important. But the men of his
own time could not see this. What they fastened upon was the obvious
aspect of Socrates, his ethics, and above all the ethical teaching
which was expressed, not so {157} much in abstract ideas, as in the
life and personality of the master. Both this life and this teaching
might be summed up in the thought that virtue is the sole end of life,
that, as against virtue, all else in the world, comfort, riches,
learning, is comparatively worthless. It is this, then, that virtue is
the sole end of life, which forms the point of agreement between all
the three semi-Socratic schools. We have now to see upon what points
they diverge from one another.
If virtue is the sole end of life, what precisely is virtue? Socrates
had given no clear answer to this question. The only definition he had
given was that virtue is knowledge, but upon examination it turns out
that this is not a definition at all. Virtue is knowledge, but
knowledge of what? It is not knowledge of astronomy, of mathematics,
or of physics. It is ethical knowledge, that is to say, knowledge of
virtue. To define virtue as the knowledge of virtue is to think in a
circle, and gets us no further in the enquiry what virtue is. But
Socrates, as a matter of fact, did not think in a circle. He did not
mean that virtue is knowledge, although his doctrine is often,
somewhat misleadingly, stated in that form. What he meant was--quite a
different thing--that virtue _depends upon_ knowledge. It is the first
condition of virtue. The principle, accurately stated, is, not that
virtue is the knowledge of virtue, which is thinking in a circle, but
that virtue depends upon the knowledge of virtue, which is quite
straight thinking. Only if you know what virtue is can you be
virtuous. Hence we have not here any definition of virtue, or any
attempt to define it. We are still left with the question, "what is
virtue?" unanswered.
{158}
No doubt this was due in part to the unmethodical and unsystematic
manner in which Socrates developed his thought, and this, in its turn,
was due to his conversational style of philosophizing. For it is not
possible to develop systematic thinking in the course of casual
conversations. But in part, too, it was due to the very universality
of the man's genius. He was broad enough to realize that it is not
possible to tie down virtue in any single narrow formula, which shall
serve as a practical receipt for action in all the infinitely various
circumstances of life. So that, in spite of the fact that his whole
principle lay in the method of definitions, Socrates, in fact, left
his followers without any definition of the supreme concept of his
philosophy, virtue. It was upon this point, therefore, that the
followers of Socrates disagreed. They all agreed that virtue is the
sole end of life, but they developed different ideas as to what sort
of life is in fact virtuous.
The Cynics.
Antisthenes, the founder of the Cynic School, repeated the familiar
propositions that virtue is founded upon knowledge, is teachable, and
is one. But what aroused the admiration of Antisthenes was not
Socrates, the man of intellect, the man of science, the philosopher,
but Socrates, the man of independent character, who followed his own
notions of right with complete indifference to the opinions of others.
This independence was in fact merely a by-product of the Socratic
life. Socrates had been independent of all earthly goods and
possessions, caring neither for riches nor for applause, only because
his heart was set upon a greater treasure, the acquisition of wisdom.
Mere independence and indifference to the {159} opinions of others
were not for him ends in themselves. He did not make fetishes of them.
But the Cynics interpreted his teaching to mean that the independence
of earthly pleasures and possessions is in itself the end and object
of life. This, in fact, was their definition of virtue, complete
renunciation of everything that, for ordinary men, makes life worth
living, absolute asceticism, and rigorous self-mortification.
Socrates, again, thinking that the only knowledge of supreme value is
ethical knowledge, had exhibited a tendency to disparage other kinds
of knowledge. This trait the Cynics exaggerated into a contempt for
all art and learning so great as frequently to amount to ignorance and
boorishness. "Virtue is sufficient for happiness," said Antisthenes,
"and for virtue nothing is requisite but the strength of a Socrates;
it is a matter of action, and does not require many words, or much
learning." The Cynic ideal of virtue is thus purely negative; it is
the absence of all desire, freedom from all wants, complete
independence of all possessions. Many of them refused to own houses or
any dwelling place, and wandered about as vagrants and beggars.
Diogenes, for the same reason, lived in a tub. Socrates, following
single-heartedly what he knew to be good, cared nothing what the
vulgar said. But this indifference to the opinion of others was, like
his independence of possessions, not an end in itself. He did not
interpret it to mean that he was wantonly to offend public opinion.
But the Cynics, to show their indifference, flouted public opinion,
and gave frequent and disgusting exhibitions of indecency.
Virtue, for the Cynics, is alone good. Vice is the only evil. Nothing
else in the world is either good or bad. {160} Everything else is
"indifferent." Property, pleasure, wealth, freedom, comfort, even life
itself, are not to be regarded as goods. Poverty, misery, illness,
slavery, and death itself, are not to be regarded as evils. It is no
better to be a freeman than a slave, for if the slave have virtue, he
is in himself free, and a born ruler. Suicide is not a crime, and a
man may destroy his life, not however to escape from misery and pain
(for these are not ills), but to show that for him life is
indifferent. And as the line between virtue and vice is absolutely
definite, so is the distinction between the wise man and the fool. All
men are divided into these two classes. There is no middle term
between them. Virtue being one and indivisible, either a man possesses
it whole or does not possess it at all. In the former case he is a
wise man, in the latter case a fool. The wise man possesses all
virtue, all knowledge, all wisdom, all happiness, all perfection. The
fool possesses all evil, all misery, all imperfection.
The Cyrenaics.
For the Cyrenaics, too, virtue is, at least formally, the sole object
of life. It is only formally, however, because they give to virtue a
definition which robbed it of all meaning. Socrates had not
infrequently recommended virtue on account of the advantages which it
brings. Virtue, he said, is the sole path to happiness, and he had not
refrained from holding out happiness as a motive for virtue. This did
not mean, however, that he did not recognize a man's duty to do the
right for its own sake, and not for the sake of the advantage it
brings. "Honesty," we say, "is the best policy," {161} but we do not
mean thereby to deny that it is the duty of men to be honest even if
it is not, in some particular case, the best policy. Socrates,
however, had not been very clear upon these points, and had been
unable to find any definite basis for morality, other than that of
happiness. It was this side of his teaching which Aristippus now
pressed to its logical conclusions, regardless of all other claims.
Doubtless virtue is the sole end of life, but the sole end of virtue
is one's own advantage, that is to say, pleasure. One may as well say
at once that the sole end of life is pleasure.
The influence of Protagoras and the Sophists also played its part in
moulding the thought of Aristippus. Protagoras had denied the
objectivity of truth, and the later Sophists had applied the same
theory to morals. Each man is a law unto himself. There is no moral
code binding upon the individual against his own wishes. Aristippus
combined this with his doctrine of pleasure. Pleasure being the sole
end of life, no moral law externally imposed can invalidate its
absolute claims. Nothing is wicked, nothing evil, provided only it
satisfies the individual's thirst for pleasure.
Whether such a philosophy will lead, in practice, to the complete
degradation of its devotees, depends chiefly upon what sort of
pleasure they have in mind. If refined and intellectual pleasures are
meant, there is no reason why a comparatively good life should not
result. If bodily pleasures are intended, the results are not likely
to be noble. The Cyrenaics by no means wholly ignored the pleasures of
the mind, but they pointed out that feelings of bodily pleasure are
more potent and intense, and it was upon these, therefore, that they
chiefly {162} concentrated their attention. Nevertheless they were
saved from the lowest abysses of sensuality and bestiality by their
doctrine that, in the pursuit of pleasure, the wise man must exercise
prudence. Completely unrestrained pursuit of pleasure leads in fact to
pain and disaster. Pain is that which has to be avoided. Therefore the
wise man will remain always master of himself, will control his
desires, and postpone a more urgent to a less urgent desire, if
thereby in the end more pleasure and less pain will accrue to him. The
Cyrenaic ideal of the wise man is the man of the world, bent indeed
solely upon pleasure, restrained by no superstitious scruples, yet
pursuing his end with prudence, foresight, and intelligence. Such
principles would, of course, admit of various interpretations,
according to the temperament of the individual. We may notice two
examples. Anniceris, the Cyrenaic, believed indeed that pleasure is
the sole end, but set such store upon the pleasures that arise from
friendship and family affection, that he admitted that the wise man
should be ready to sacrifice himself for his friends or family--a
gleam of light in the moral darkness. Hegesias, a pessimist,
considered that positive enjoyment is impossible of attainment. In
practice the sole end of life which can be realized is the avoidance
of pain.
The Megarics.
Euclid of Megara was the founder of this school. His principle was a
combination of Socraticism with Eleaticism. Virtue is knowledge, but
knowledge of what? It is here that the Eleatic influence became
visible. With Parmenides, the Megarics believed in the One Absolute
Being. All multiplicity, all motion, are illusory. {163} the world of
sense has in it no true reality. Only Being is. If virtue is
knowledge, therefore, it can only be the knowledge of this Being. If
the essential concept of Socrates was the Good and the essential
concept of Parmenides Being, Euclid now combined the two. The Good is
identified with Being. Being, the One, God, the Good, divinity, are
merely different names for one and the same thing. Becoming, the many,
Evil, are the names of its opposite, not-being, Multiplicity is thus
identified with evil, and both are declared illusory. Evil has no real
existence. The Good alone truly is. The various virtues, as
benevolence, temperance, prudence, are merely different names for the
one virtue, knowledge of Being.
Zeno, the Eleatic, had shown that multiplicity and motion are not only
unreal but even impossible, since they are self-contradictory. The
Megarics appropriated this idea, together with the dialectic of Zeno,
and concluded that since not-being is impossible, Being includes all
possibility. Whatever is possible is also actual. There is no such
thing as a possible something, which yet does not exist.
As the Cynics found virtue in renunciation and negative independence,
the Cyrenaics in the hedonistic pursuit of pleasure, so the Megarics
find it in the life of philosophic contemplation, the knowledge of
Being.
{164}
CHAPTER XII
PLATO
None of the predecessors of Plato had constructed a system of
philosophy. What they had produced, and in great abundance, were
isolated philosophical ideas, theories, hints, and suggestions. Plato
was the first person in the history of the world to produce a great
all-embracing system of philosophy, which has its ramifications in all
departments of thought and reality. In doing this, Plato laid all
previous thought under contribution. He gathered the entire harvest of
Greek philosophy. All that was best in the Pythagoreans, the Eleatics,
Heracleitus, and Socrates, reappears, transfigured in the system of
Plato. But it is not to be imagined, on this account, that Plato was a
mere eclectic, or a plagiarist, who took the best thoughts of others,
and worked them into some sort of a patch-work philosophy of his own.
He was, on the contrary, in the highest degree an original thinker.
But like all great systems of thought, that of Plato grows out of the
thought of previous thinkers. He does indeed appropriate the ideas of
Heracleitus, Parmenides, and Socrates. But he does not leave them as
he finds them. He takes them as the germs of a new development. They
are the foundations, below ground, upon which he builds the palace of
philosophy. In his hands, all previous thought becomes {165}
transfigured under the light of a new and original principle.
1. Life and Writings.
The exact date of the birth of Plato is a matter of doubt. But the
date usually given, 429-7 B.C. cannot be far wrong. He came of an
aristocratic Athenian family, and was possessed of sufficient wealth
to enable him to command that leisure which was essential for a life
devoted to philosophy. His youth coincided with the most disastrous
period of Athenian history. After a bitter struggle, which lasted over
a quarter of a century, the Peloponnesian war ended in the complete
downfall of Athens as a political power. And the internal affairs of
the State were in no less confusion than the external. Here, as
elsewhere, a triumphant democracy had developed into mob-rule. Then at
the close of the Peloponnesian war, the aristocratic party again came
into power with the Thirty Tyrants, among whom were some of Plato's
own relatives. But the aristocratic party, so far from improving
affairs, plunged at once into a reign of bloodshed, terror, and
oppression. These facts have an important bearing upon the history of
Plato's life. If he ever possessed any desire to adopt a political
career, the actual condition of Athenian affairs must have quenched
it. An aristocrat, both in thought and by birth, he could not
accommodate himself to the rule of the mob. And if he ever imagined
that the return of the aristocracy to power would improve matters, he
must have been bitterly disillusioned by the proceedings of the Thirty
Tyrants. Disgusted alike with the democracy and the aristocracy he
seems to have retired into seclusion. He never once, throughout his
long life, appeared as a {166} speaker in the popular assembly. He
regarded the Athenian constitution as past help.
Not much is known of the philosopher's youth. He composed poems. He
was given the best education that an Athenian citizen of those days
could obtain. His teacher, Cratylus, was a follower of Heracleitus,
and Plato no doubt learned from him the doctrines of that philosopher.
It is improbable that he allowed himself to remain unacquainted with
the disputations of the Sophists, many of whom were his own
contemporaries. He probably read the book of Anaxagoras, which was
easily obtainable in Athens at the time. But on all these points we
have no certain information. What we do know is that the decisive
event in his youth, and indeed in his life, was his association with
Socrates.
For the last eight years of the life of Socrates, Plato was his friend
and his faithful disciple. The teaching and personality of the master
constituted the supreme intellectual impulse of his life, and the
inspiration of his entire thought. And the devotion and esteem which
he felt for Socrates, so far from waning as the years went by, seem,
on the contrary, to have grown continually stronger. For it is
precisely in the latest dialogues of his long life that some of the
most charming and admiring portraits of Socrates are to be found.
Socrates became for him the pattern and exemplar of the true
philosopher.
After the death of Socrates a second period opens in the life of
Plato, the period of his travels. He migrated first to Megara, where
his friend and fellow-disciple Euclid was then founding the Megaric
school. The Megaric philosophy was a combination of the thought of
Socrates with that of the Eleatics. And it was no doubt here, at {167}
Megara, under the influence of Euclid, that Plato formed his deeper
acquaintance with the teaching of Parmenides, which exercised an
all-important influence upon his own philosophy. From Megara he
travelled to Cyrene, Egypt, Italy, and Sicily. In Italy he came in
contact with the Pythagoreans. And to the effects of this journey may
be attributed the strong Pythagorean elements which permeate his
thought.
In Sicily he attended the court of Dionysius the Elder, tyrant of
Syracuse. But here his conduct seems to have given grave offence.
Dionysius was so angered by his moralizings and philosophical
diatribes that he put Plato up to auction in the slave market. Plato
narrowly escaped the fate of slavery, but was ransomed by Anniceris,
the Cyrenaic. He then returned to Athens, his travels having occupied
a period of about ten years.
With the return of Plato to Athens we enter upon the third and last
period of his life. With the exception of two journeys to be mentioned
shortly, he never again left Athens. He now appeared for the first
time as a professional teacher and philosopher. He chose for the scene
of his activities a gymnasium, called the Academy. Here he gradually
collected round him a circle of pupils and disciples. For the rest of
his life, a period of about forty years, he occupied himself in
literary activity, and in the management of the school which he had
founded. His manner of life was in strong contrast to that of
Socrates. Only in one respect did he resemble his master. He took no
fees for his teaching. Otherwise the lives of the two great men bear
no resemblance to each other. Socrates had gone out into the highways
and byways in search of wisdom. He had wrangled in {168} the
market-place with all comers. Plato withdrew himself into the
seclusion of a school, protected from the hubbub of the world by a
ring of faithful disciples. It was not to be expected that a man of
Plato's refinement, culture, and aristocratic feelings, should
appreciate, as Socrates, the man of the people, had done, the
rough-and-tumble life of the Athenian market-place. Nor was it
desirable for the advancement of philosophy that it should be so. The
Socratic philosophy had suffered from the Socratic manner of life. It
was unmethodical and inchoate. Systematic thought is not born of
disputes at the street corner. For the development of a great
world-system, such as that of Plato, laborious study and quiet
seclusion were essential.
This period of Plato's mastership was broken only by two journeys to
Sicily, both undertaken with political objects. Plato knew well that
the perfect State, as depicted in his "Republic," was not capable of
realization in the Greece of his own time. Nevertheless, he took his
political philosophy very seriously. Though the perfect republic was
an unattainable ideal, yet, he thought, any real reform of the State
must at least proceed in the direction of that ideal. One of the
essential principles of the "Republic" was that the rulers must also
be philosophers. Not till philosopher and ruler were combined in one
and the same person could the State be governed upon true principles.
Now, in the year 368 B.C., Dionysius the Elder died, and Dionysius the
younger became tyrant of Syracuse. Dionysius despatched an invitation
to Plato to attend his court and give him the benefit of his advice.
Here was an opportunity to experiment. Plato could train and educate a
{169} philosopher-king. He accepted the invitation. But the expedition
ended disastrously. Dionysius received him with enthusiasm, and
interested himself in the philosophical discourses of his teacher. But
he was young, impetuous, hot-headed, and without genuine philosophic
bent. His first interest gave place to weariness and irritation. Plato
left Syracuse a disappointed man; and returned to Athens.
Nevertheless, after the lapse of a few years, Dionysius again invited
him to Syracuse, and again he accepted the invitation. But the second
journey ended in disaster like the first, and Plato was even in danger
of his life, but was rescued by the intervention of the Pythagoreans.
He returned to Athens in his seventieth year, and lived till his death
in the seclusion of his school, never again attempting to intervene in
practical politics.
For more than another decade he dwelt and taught in Athens. His life
was serene, quiet, and happy. He died peacefully at the age of
eighty-two.
Plato's writings take the form of dialogues. In the majority of these,
the chief part is taken by Socrates, into whose mouth Plato puts the
exposition of his own philosophy. In a few, as for example the
"Parmenides," other speakers enunciate the Platonic teaching, but even
in these Socrates always plays an important _rôle_. Plato was not only
a philosopher, but a consummate literary artist. The dialogues are
genuinely dramatic, enlivened by incident, humour, and life-like
characterization. Not only is the portrait of Socrates drawn with
loving affection, but even the minor characters are flesh and blood.
A most important element of Plato's style is his use of myths. He does
not always explain his meaning in {170} the form of direct scientific
exposition. He frequently teaches by allegories, fables, and stories,
all of which may be included under the one general appellation of
Platonic myths. These are often of great literary beauty, but in spite
of this they involve grave disadvantages. Plato slips so easily from
scientific exposition into myth, that it is often no easy matter to
decide whether his statements are meant literally or allegorically.
Moreover, the myths usually signify a defect in his thought itself.
The fact is that the combination of poet and philosopher in one man is
an exceedingly dangerous combination. I have explained before that the
object of philosophy is, not merely to feel the truth, as the poet and
mystic feel it, but intellectually to comprehend it, not merely to
give us a series of pictures and metaphors, but a reasoned explanation
of things upon scientific principles. When a man, who is at once a
poet and a philosopher, cannot rationally explain a thing, it is a
terrible temptation to him to substitute poetic metaphors for the
explanation which is lacking. We saw, for example, that the writers of
the Upanishads, who believed that the whole world issues forth from
the one, absolute, imperishable, being, which they called Brahman,
being unable to explain why the One thus differentiates itself into
the many, took refuge in metaphors. As the sparks from the substantial
fire, so, they say, do all finite beings issue forth from the One. But
this explains nothing, and the aim of the philosopher is not thus
vaguely to feel, but rationally to understand. Now this is not merely
my view of the functions of philosophy. It is emphatically Plato's own
view. In fact Plato was the originator of it. He is perpetually
insisting that {171} nothing save full rational comprehension deserves
the names of knowledge and philosophy. No writer has ever used such
contemptuous language as Plato used of the mere mystic and poet, who
says wise and beautiful things, without in the least understanding why
they are wise and beautiful. No man has formed such a low estimate of
the functions of the poet and mystic. Plato is, in theory at least,
the prince of rationalists and intellectualists. In practice, however,
he must be convicted of the very fault he so severely censured in
others. This, in fact, is the explanation of most of the Platonic
myths. Wherever Plato is unable to explain anything, he covers up the
gap in his system with a myth. This is particularly noticeable, for
example, in the "Timaeus." Plato having, in other dialogues, developed
his theory of the nature of the ultimate reality, arrives, in the
"Timaeus," at the problem how the actual world is to be explained from
that ultimate reality. At this point, as we shall see, Plato's system
breaks down. His account of the absolute reality is defective, and in
consequence, it affords no principle whereby the actual universe can
be explained. In the "Timaeus," therefore, instead of a reasoned
explanation, he gives us a series of wholly fanciful myths about the
origin of the world. Wherever we find myths in Plato's dialogues, we
may suspect that we have arrived at one of the weak points of the
system.
If we are to study Plato intelligently, it is essential that we should
cease to regard the dialogues as if they were all produced _en bloc_
from a single phase of their author's mind. His literary activity
extended over a period of not less than fifty years. During that time,
he did not stand still. His thought, and his mode of {172} expression,
were constantly developing. If we are to understand Plato, we must
obtain some clue to enable us to trace this development. And this
means that we must know something of the order in which the dialogues
were written. Unfortunately, however, they have not come down to us
dated and numbered. It is a matter of scholarship and criticism to
deduce the period at which any dialogue was written from internal
evidences. Many minor points are still undecided, as well as a few
questions of importance, such as the date of the "Phaedrus," [Footnote
11] which some critics place quite early and some very late in Plato's
life. Neglecting these points, however, we may say in general that
unanimity has been reached, and that we now know enough to be able to
trace the main lines of development.
[Footnote 11: The same remark applies to the "Symposium," the
"Republic," and the "Theaetetus."]
The dialogues fall into three main groups, which correspond roughly to
the three periods of Plato's life. Those of the earliest group were
written about the time of the death of Socrates, and before the
author's journey to Megara. Some of them may have been written before
the death of Socrates. This group includes the "Hippias Minor," the
"Lysis," the "Charmides," the "Laches," the "Euthyphro," the
"Apology," the "Crito," and the "Protagoras." The "Protagoras" is the
longest, the most complex in thought, and the most developed. It is
probably the latest, and forms the bridge to the second group.
All these early dialogues are short and simple, and are still, as
regards their thought, entirely under the influence of Socrates. Plato
has not as yet developed {173} any philosophy of his own. He propounds
the philosophy of Socrates almost unaltered. Even so, however, he is
no mere plagiarist. There are throughout these dialogues evidences of
freshness and originality, but these qualities exhibit themselves
rather in the literary form than in the philosophical substance. We
find here all the familiar Socratic propositions, that virtue is
knowledge, is one, is teachable; that all men seek the good, but that
men differ as to what the good is; that a man who does wrong
deliberately is better than a man who does it unintentionally; and so
on. Moreover, just as Socrates had occupied himself in attempting to
fix the concepts of the virtues, asking "what is prudence?", "what is
temperance?", and the like, so in many of these dialogues Plato
pursues similar inquiries. The "Lysis" discusses the concept of
friendship, the "Charmides" of temperance, the "Laches" of bravery. On
the whole, the philosophical substance of these early writings is thin
and meagre. There is a preponderance of incident and much biographical
detail regarding Socrates. There is more art than matter.
Consequently, from a purely literary point of view, these are among
the most charming of Plato's dialogues, and many of them, such as the
"Apology" and the "Crito," are especially popular with those who care
for Plato rather as an artist than as a philosopher.
The second group of dialogues is generally connected with the period
of Plato's travels. In addition to the influence of Socrates, we have
now the influence of the Eleatics, which naturally connects these
dialogues with the period of the philosopher's sojourn at Megara. But
it is in these dialogues, too, that Plato for the first time {174}
develops his own special philosophical thesis. This is in fact his
great constructive period. The central and governing principle of his
philosophy is the theory of Ideas. All else hinges on this, and is
dominated by this. In a sense, his whole philosophy is nothing but the
theory of Ideas and what depends upon it. It is in this second period
that the theory of Ideas is founded and developed, and its
relationship to the Eleatic philosophy of Being discussed. We have
here the spectacle of Plato's most original thoughts in the pangs of
childbirth. He is now at grips with the central problems of
philosophy. He is intent upon the thought itself, and cares little for
the ornaments of style. He is struggling to find expression for ideas
newly-formed in his mind, of which he is not yet completely master,
and which he cannot manipulate with ease. Consequently, the literary
graces of the first period recede into the background. There is little
incident, and no humour. There is nothing but close reasoning, hard
and laborious discussion.
The twin dialogues, "Gorgias" and "Theaetetus" are probably the
earliest of this group. They result in nothing very definite, and are
chiefly negative in character. Plato is here engaged merely in a
preparatory clearing of the ground. The "Gorgias" discusses and
refutes the Sophistic identification of virtue and pleasure, and
attempts to show, as against it, that the good must be something
objectively existent, and independent of the pleasure of the
individual. The "Theaetetus," similarly, shows that truth is not, as
the Sophists thought, merely the subjective impression of the
individual, but is something objectively true in itself. The other
{175} dialogues of the group are the "Sophist," the "Statesman," and
the "Parmenides." The "Sophist" discusses Being and not-being, and
their relationship to the theory of Ideas. The "Parmenides" inquires
whether the absolute reality is to be regarded, in the manner of the
Eleatics, as an abstract One. It gives us, therefore, Plato's
conception of the relation of his own philosophy to Eleaticism.
The dialogues of the third group are the work of Plato's maturity. He
has now completely mastered his thought, and turns it with ease in all
directions. Hence the style returns to the lucidity and purity of the
first period. If the first period was marked chiefly by literary
grace, the second by depth of thought, the third period combines both.
The perfect substance is now moulded in the perfect form. But a
peculiarity of all the dialogues of this period is that they take it
for granted that the theory of Ideas is already established and
familiar to the reader. They proceed to apply it to all departments of
thought. The second period was concerned with the formulation and
proof of the theory of Ideas, the third period undertakes its
systematic application. Thus the "Symposium," which has for its
subject the metaphysic of love, attempts to connect man's feeling for
beauty with the intellectual knowledge of the Ideas. The "Philebus"
applies the theory of Ideas to the sphere of ethics, the "Timaeus" to
the sphere of physics, and the "Republic" to the sphere of politics.
The "Phaedo" founds the doctrine of the immortality of the soul upon
the theory of Ideas. The "Phaedrus" is probably to be grouped with the
"Symposium." The beauty, grace, and lucidity of the style, and the
fact that it assumes throughout that {176} the theory of Ideas is a
thing established, lead us to the belief that it belongs to the period
of Plato's maturity. Zeller's theory that it was written at the
beginning of the second period, and is then offered to the reader as a
sort of sweetmeat to induce him to enter upon the laborious task of
reading the "Sophist," the "Statesman," and the "Parmenides," seems to
be far-fetched and unnecessary. [Footnote 12]
[Footnote 12: Zeller's _Plato and the Older Academy_, chap. iii.]
If the second is the great constructive period of Plato's life, the
third may be described as his systematic and synthetic period. Every
part of his philosophy is here linked up with every other part. All
the details of the system are seen to flow from the one central
principle of his thought, the theory of Ideas. Every sphere of
knowledge and being is in turn exhibited in the light of that
principle, is permeated and penetrated by it.
The plan for expounding Plato which first suggests itself is to go
through the dialogues, one by one, and extract the doctrine of each
successively. But this suggestion has to be given up as soon as it is
mentioned. For although the philosophy of Plato is in itself a
systematic and coherent body of thought, he did not express it in a
systematic way. On the contrary, he scatters his ideas in all
directions. He throws them out at random in any order. What logically
comes first often appears last. It may be found at the end of a
dialogue, and the next step in reasoning may make its appearance at
the beginning, or even in a totally different dialogue. If, therefore,
we are to get any connected view of the system, we must abandon
Plato's own order of exposition, and piece the thought together for
ourselves. We must begin {177} with what logically comes first,
wherever we may find it, and proceed with the exposition in the same
manner.
A similar difficulty attends the question of the division of Plato's
philosophy. He himself has given us no single and certain principle of
division. But the principle usually adopted divides his philosophy
into Dialectic, Physics, and Ethics. Dialectic, or the theory of
Ideas, is Plato's doctrine of the nature of the absolute reality.
Physics is the theory of phenomenal existence in space and time, and
includes therefore the doctrine of the soul and its migrations, since
these are happenings in time. Ethics includes politics, the theory of
the duty of man as a citizen, as well as the ethics of the individual.
Certain portions of the system, the doctrine of Eros, for example, do
not fall very naturally into any of these divisions. But, on the other
hand, though some dialogues are mixed as to their subject matter,
others, and those the most important, fall almost exclusively into one
or other division. For example, the "Timaeus," the "Phaedo," and the
"Phaedrus," are physical. The "Philebus," the "Gorgias," and the
"Republic," are ethical. The "Theaetetus," the "Sophist," and the
"Parmenides," are dialectical.
2. The Theory of Knowledge.
The theory of Ideas is itself based upon the theory of knowledge. What
is knowledge? What is truth? Plato opens the discussion by telling us
first what knowledge and truth are not. His object here is the
refutation of false theories. These must be disposed of to clear the
ground preparatory to positive exposition. The first such false theory
which he attacks is that knowledge {178} is perception. To refute this
is the main object of the "Theaetetus." His arguments may be
summarized as follows:--
(1) That knowledge is perception is the theory of Protagoras and the
Sophists, and we have seen to what results it leads. What it amounts
to is that what appears to each individual true is true for that
individual. But this is at any rate false in its application to our
judgment of future events. The frequent mistakes which men make about
the future show this. It may appear to me that I shall be Chief
Justice next year. But instead of that, I find myself, perhaps, in
prison. In general, what appears to each individual to be the truth
about the future frequently does not turn out so in the event.
(2) Perception yields contradictory impressions. The same object
appears large when near, small when removed to a distance. Compared
with some things it is light, with others heavy. In one light it is
white, in another green, and in the dark it has no colour at all.
Looked at from one angle this piece of paper seems square, from
another it appears to be a rhombus. Which of all these impressions is
true? To know which is true, we must be able to exercise a choice
among these varying impressions, to prefer one to another, to
discriminate, to accept this and reject that. But if knowledge is
perception, then we have no right to give one perception preference
over another. For all perceptions are knowledge. All are true.
(3) This doctrine renders all teaching, all discussion, proof, or
disproof, impossible. Since all perceptions are equally true, the
child's perceptions must be just as much the truth as those of his
teachers. His teachers, {179} therefore, can teach him nothing. As to
discussion and proof, the very fact that two people dispute about
anything implies that they believe in the existence of an objective
truth. Their impressions, if they contradict each other, cannot both
be true. For if so, there is nothing to dispute about. Thus all proof
and refutation are rendered futile by the theory of Protagoras.
(4) If perception is truth, man is the measure of all things, in his
character as a percipient being. But since animals are also percipient
beings, the lowest brute must be, equally with man, the measure of all
things.
(5) The theory of Protagoras contradicts itself. For Protagoras admits
that what appears to me true is true. If, therefore, it appears to me
true that the doctrine of Protagoras is false, Protagoras himself must
admit that it is false.
(6) It destroys the objectivity of truth, and renders the distinction
between truth and falsehood wholly meaningless. The same thing is true
and false at the same time, true for you and false for me. Hence it
makes no difference at all whether we say that a proposition is true,
or whether we say that it is false. Both statements mean the same
thing, that is to say, neither of them means anything. To say that
whatever I perceive is true for me merely gives a new name to my
perception, but does not add any value to it.
(7) In all perception there are elements which are not contributed by
the senses. Suppose I say, "This piece of paper is white." This, we
might think, is a pure judgment of perception. Nothing is stated
except what I perceive by means of my senses. But on consideration it
turns out that this is not correct. First of all I must {180} think
"this piece of paper." Why do I call it paper? My doing so means that
I have classified it. I have mentally compared it with other pieces of
paper, and decided that it is of a class with them. My thought, then,
involves comparison and classification. The object is a compound
sensation of whiteness, squareness, etc. I can only recognise it as a
piece of paper by identifying these sensations, which I have now, with
sensations received from other similar objects in the past. And not
only must I recognize the sameness of the sensations, but I must
recognize their difference from other sensations. I must not confound
the sensations I receive from paper with those which I receive from a
piece of wood. Both identities and differences of sensations must be
known before I can say "this piece of paper." The same is true when I
go on to say that it "is white." This is only possible by classifying
it with other white objects, and differentiating it from objects of
other colours. But the senses themselves cannot perform these acts of
comparison and contrast. Each sensation is, so to speak, an isolated
dot. It cannot go beyond itself to compare itself with others. This
operation must be performed by my mind, which acts as a co-ordinating
central authority, receiving the isolated sensations, combining,
comparing, and contrasting them. This is particularly noticeable in
cases where we compare sensations of one sense with those of another.
Feeling a ball with my fingers, I say it feels round. Looking at it
with my eyes, I say it looks round. But the feel is quite a different
sensation from the look. Yet I use the same word, "round," to describe
both. And this shows that I have identified the two sensations. This
{181} cannot be done by the senses themselves. For my eyes cannot
feel, and my fingers cannot see. It must be the mind itself, standing
above the senses, which performs the identification. Thus the ideas of
identity and difference are not yielded to me by my senses. The
intellect itself introduces them into things. Yet they are involved in
all knowledge, for they are involved even in the simplest acts of
knowledge, such as the proposition, "This is white." Knowledge,
therefore, cannot consist simply of sense-impressions, as Protagoras
thought, for even the simplest propositions contain more than
sensation.
If knowledge is not the same as perception, neither is it, on the
other hand, the same as opinion. That knowledge is opinion is the
second false theory that Plato seeks to refute. Wrong opinion is
clearly not knowledge. But even right opinion cannot be called
knowledge. If I say, without any grounds for the statement, that there
will be a thunderstorm next Easter Sunday, it may chance that my
statement turns out to be correct. But it cannot be said that, in
making this blind guess, I had any knowledge, although, as it turned
out, I had right opinion. Right opinion may also be grounded, not on
mere guess-work, but on something which, though better, is still not
true understanding. We often feel intuitively, or instinctively, that
something is true, though we cannot give any definite grounds for our
belief. The belief may be quite correct, but it is not, according to
Plato, knowledge. It is only right opinion. To possess knowledge, one
must not only know that a thing is so, but why it is so. One must know
the reasons. Knowledge must be full and complete understanding,
rational comprehension, and not mere instinctive belief. {182} It must
be grounded on reason, and not on faith. Right opinion may be produced
by persuasion and sophistry, by the arts of the orator and
rhetorician. Knowledge can only be produced by reason. Right opinion
may equally be removed by the false arts of rhetoric, and is therefore
unstable and uncertain. But true knowledge cannot be thus shaken. He
who truly knows and understands cannot be robbed of his knowledge by
the glamour of words. Opinion, lastly, may be true or false. Knowledge
can only be true.
These false theories being refuted, we can now pass to the positive
side of the theory of knowledge. If knowledge is neither perception
nor opinion, what is it? Plato adopts, without alteration, the
Socratic doctrine that all knowledge is knowledge through concepts.
This, as I explained in the lecture on Socrates, gets rid of the
objectionable results of the Sophistic identification of knowledge
with perception. A concept, being the same thing as a definition, is
something fixed and permanent, not liable to mutation according to the
subjective impressions of the individual. It gives us objective truth.
This also agrees with Plato's view of opinion. Knowledge is not
opinion, founded on instinct or intuition. Knowledge is founded on
reason. This is the same as saying that it is founded upon concepts,
since reason is the faculty of concepts.
But if Plato, in answering the question, "What is knowledge?" follows
implicitly the teaching of Socrates, he yet builds upon this teaching
a new and wholly un-Socratic metaphysic of his own. The Socratic
theory of knowledge he now converts into a theory of the nature of
reality. This is the subject-matter of Dialectic.
{183}
3. Dialectic, or the Theory of Ideas.
The concept had been for Socrates merely a rule of thought.
Definitions, like guide-rails, keep thought upon the straight path; we
compare any act with the definition of virtue in order to ascertain
whether it is virtuous. But what was for Socrates merely regulative of
thought, Plato now transforms into a metaphysical substance. His
theory of Ideas is the theory of the objectivity of concepts. That the
concept is not merely an idea in the mind, but something which has a
reality of its own, outside and independent of the mind--this is the
essence of the philosophy of Plato.
How did Plato arrive at this doctrine? It is founded upon the view
that truth means the correspondence of one's ideas with the facts of
existence. If I see a lake of water, and if there really is such a
lake, then my idea is true. But if there is no lake, then my idea is
false. It is an hallucination. Truth, according to this view, means
that the thought in my mind is a copy of something outside my mind.
Falsehood consists in having an idea which is not a copy of anything
which really exists. Knowledge, of course, means knowledge of the
truth. And when I say that a thought in my mind is knowledge, I must
therefore mean that this thought is a copy of something that exists.
But we have already seen that knowledge is the knowledge of concepts.
And if a concept is true knowledge, it can only be true in virtue of
the fact that it corresponds to an objective reality. There must,
therefore, be general ideas or concepts, outside my mind. It were a
contradiction to suppose, on the one hand, that the concept is true
knowledge, and on the other, that it corresponds to nothing external
{184} to us. This would be like saying that my idea of the lake of
water is a true idea, but that no such lake really exists. The concept
in my mind must be a copy of the concept outside it.
Now if knowledge by concepts is true, our experiences through
sensation must be false. Our senses make us aware of many individual
horses. Our intellect gives us the concept of the horse in general. If
the latter is the sole truth, the former must be false. And this can
only mean that the objects of sensation have no true reality. What has
reality is the concept; what has no reality is the individual thing
which is perceived by the senses. This and that particular horse have
no true being. Reality belongs only to the idea of the horse in
general.
Let us approach this theory from a somewhat different direction.
Suppose I ask you the question, "What is beauty?" You point to a rose,
and say, "Here is beauty." And you say the same of a woman's face, a
piece of woodland scenery, and a clear moonlight night. But I answer
that this is not what I want to know. I did not ask what things are
beautiful, but what is beauty. I did not ask for many things, but for
one thing, namely, beauty. If beauty is a rose, it cannot be
moonlight, because a rose and moonlight are quite different things. By
beauty we mean, not many things, but one. This is proved by the fact
that we use only one word for it. And what I want to know is what this
one beauty is, which is distinct from all beautiful objects. Perhaps
you will say that there is no such thing as beauty apart from
beautiful objects, and that, though we use one word, yet this is only
a manner of {185} speech, and that there are in reality many beauties,
each residing in a beautiful object. In that case, I observe that,
though the many beauties are all different, yet, since you use the one
word to describe them all, you evidently think that they are similar
to each other. How do you know that they are similar? Your eyes cannot
inform you of this similarity, because it involves comparison, and we
have already seen that comparison is an act of the mind, and not of
the senses. You must therefore have an idea of beauty in your mind,
with which you compare the various beautiful objects and so recognise
them as all resembling your idea of beauty, and therefore as
resembling each other. So that there is at any rate an idea of one
beauty in your mind. Either this idea corresponds to something outside
you, or it does not. In the latter case, your idea of beauty is a mere
invention, a figment of your own brain. If so, then, in judging
external objects by your subjective idea, and in making it the
standard of whether they are beautiful or not, you are back again at
the position of the Sophists. You are making yourself and the fancies
of your individual brain the standard of external truth. Therefore,
the only alternative is to believe that there is not only an idea of
beauty in your mind, but that there is such a thing as the one beauty
itself, of which your idea is a copy. This beauty exists outside the
mind, and it is something distinct from all beautiful objects.
What has been said of beauty may equally be said of justice, or of
goodness, or of whiteness, or of heaviness. There are many just acts,
but only one justice, since we use one word for it. This justice must
be a real thing, distinct from all particular just acts. Our ideas of
justice {186} are copies of it. So also there are many white objects,
but also the one whiteness.
Of the above examples, several are very exalted moral ideas, such as
beauty, justice, and goodness. But the case of whiteness will serve to
show that the theory attributes reality not only to exalted ideas, but
to others also. In fact, we might quite well substitute evil for
goodness, and all the same arguments would apply. Or we might take a
corporeal object such as the horse, and ask what "horse" means. It
does not mean the many individual horses, for since one word is used
it must mean one thing, which is related to individual horses, just as
whiteness is related to individual white things. It means the
universal horse, the idea of the horse in general, and this, just as
much as goodness or beauty, must be something objectively real.
Now beauty, justice, goodness, whiteness, the horse in general, are
all concepts. The idea of beauty is formed by including what is common
to all beautiful objects, and excluding those points in which they
differ. And this, as we have seen, is just what is meant by a concept.
Plato's theory, therefore, is that concepts are objective realities.
And he gives to these objective concepts the technical name Ideas.
This is his answer to the chief question of philosophy, namely, what,
amid all the appearances and unrealities of things, is that absolute
and ultimate reality, from which all else is to be explained? It
consists, for Plato, in Ideas.
Let us see next what the characteristics of the Ideas are. In the
first place, they are substances. Substance is a technical term in
philosophy, but its philosophical meaning is merely a more consistent
development of its {187} popular meaning. In common talk, we generally
apply the word substance to material things such as iron, brass, wood,
or water. And we say that these substances possess qualities. For
example, hardness and shininess are qualities of the substance iron.
The qualities cannot exist apart from the substances. They do not
exist on their own account, but are dependent on the substance. The
shininess cannot exist by itself. There must be a shiny something.
But, according to popular ideas, though the qualities are not
independent of the substance, the substance is independent of the
qualities. The qualities derive their reality from the substance. But
the substance has reality in itself. The philosophical use of the term
substance is simply a more consistent application of this idea.
Substance means, for the philosopher, that which has its whole being
in itself, whose reality does not flow into it from anything else, but
which is the source of its own reality. It is self-caused, and
self-determined. It is the ground of other things, but itself has no
ground except itself. For example, if we believe the popular Christian
idea that God created the world, but is Himself an ultimate and
uncreated being, then, since the world depends for its existence upon
God, but God's existence depends only upon Himself, God is a substance
and the world is not. In this sense the word is correctly used in the
Creed where it speaks of God as "three persons, but one substance."
Again, if, with the Idealists, we think that mind is a self-existent
reality, and that matter owes its existence to mind, then in that case
matter is not substance, but mind is. In this technical sense the
Ideas are substances. They are absolute and ultimate realities. {188}
Their whole being is in themselves. They depend on nothing, but all
things depend on them. They are the first principles of the universe.
Secondly, the Ideas are universal. An Idea is not any particular
thing. The Idea of the horse is not this or that horse. It is the
general concept of all horses. It is the universal horse. For this
reason the Ideas are, in modern times, often called "universals."
Thirdly, the Ideas are not things, but thoughts. There is no such
thing as the horse-in-general. If there were, we should be able to
find it somewhere, and it would then be a particular thing instead of
a universal. But in saying that the Ideas are thoughts, there are two
mistakes to be carefully avoided. The first is to suppose that they
are the thoughts of a person, that they are your thoughts or my
thoughts. The second is to suppose that they are thoughts in the mind
of God. Both these views are wrong. It would be absurd to suppose that
our thoughts can be the cause of the universe. Our concepts are indeed
copies of the Ideas, but to confuse them with the Ideas themselves is,
for Plato, as absurd as to confuse our idea of a mountain with the
mountain itself. Nor are they the thoughts of God. They are indeed
sometimes spoken of as the "Ideas in the divine mind." But this is
only a figurative expression. We can, if we like, talk of the sum of
all the Ideas as constituting the "divine mind." But this means
nothing in particular, and is only a poetical phrase. Both these
mistakes are due to the fact that we find it difficult to conceive of
thoughts without a thinker. This, however, is just what Plato meant.
They are not subjective ideas, that is, the ideas in a particular and
existent {189} mind. They are objective Ideas, thoughts which have
reality on their own account, independently of any mind.
Fourthly, each Idea is a unity. It is the one amid the many. The Idea
of man is one, although individual men are many. There cannot be more
than one Idea for each class of objects. If there were several Ideas
of justice, we should have to seek for the common element among them,
and this common element would itself constitute the one Idea of
justice.
Fifthly, the Ideas are immutable and imperishable. A concept is the
same as a definition. And the whole point in a definition is that it
should always be the same. The object of a definition is to compare
individual things with it, and to see whether they agree with it or
not. But if the definition of a triangle differed from day to day, it
would be useless, since we could never say whether any particular
figure were a triangle or not, just as the standard yard in the Tower
of London would be useless if it changed in length, and were twice as
long to-day as it was yesterday. A definition is thus something
absolutely permanent, and a definition is only the expression in words
of the nature of an Idea. Consequently the Ideas cannot change. The
many beautiful objects arise and pass away, but the one Beauty neither
begins nor ends. It is eternal, unchangeable, and imperishable. The
many beautiful things are but the fleeting expressions of the one
eternal beauty. The definition of man would remain the same, even if
all men were destroyed. The Idea of man is eternal, and remains
untouched by the birth, old age, decay, and death, of individual men.
Sixthly, the Ideas are the Essences of all things. The definition
gives us what is essential to a thing. If we {190} define man as a
rational animal, this means that reason is of the essence of man. The
fact that this man has a turned-up nose, and that man red hair, are
accidental facts, not essential to their humanity. We do not include
them in the definition of man.
Seventhly, each Idea is, in its own kind, an absolute perfection, and
its perfection is the same as its reality. The perfect man is the one
universal type-man, that is, the Idea of man, and all individual men
deviate more or less from this perfect type. In so far as they fall
short of it, they are imperfect and unreal.
Eighthly, the Ideas are outside space and time. That they are outside
space is obvious. If they were in space, they would have to be in some
particular place. We ought to be able to find them somewhere. A
telescope or microscope might reveal them. And this would mean that
they are individual and particular things, and not universals at all.
They are also outside time. For they are unchangeable and eternal; and
this does not mean that they are the same at all times. If that were
so, their immutability would be a matter of experience, and not of
reason. We should, so to speak, have to look at them from time to time
to see that they had not really changed. But their immutability is not
a matter of experience, but is known to thought. It is not merely that
they are always the same in time, but that time is irrelevant to them.
They are timeless. In the "Timaeus" eternity is distinguished from
infinite time. The latter is described as a mere copy of eternity.
Ninthly, the Ideas are rational, that is to say, they are apprehended
through reason. The finding of the common element in the manifold is
the work of inductive {191} reason, and through this alone is
knowledge of the Ideas possible. This should be noted by those persons
who imagine that Plato was some sort of benevolent mystic. The
imperishable One, the absolute reality, is apprehended, not by
intuition, or in any kind of mystic ecstasy, but only by rational
cognition and laborious thought.
Lastly, towards the end of his life, Plato identified the Ideas with
the Pythagorean numbers. We know this from Aristotle, but it is not
mentioned in the dialogues of Plato himself. It appears to have been a
theory adopted in old age, and set forth in the lectures which
Aristotle attended. It is a retrograde step, and tends to degrade the
great and lucid idealism of Plato into a mathematical mysticism. In
this, as in other respects, the influence of the Pythagoreans upon
Plato was harmful.
It results from this whole theory of Ideas that there are two sources
of human experience, sense-perception and reason. Sense-perception has
for its object the world of sense; reason has for its object the
Ideas. The world of sense has all the opposite characteristics to the
Ideas. The Ideas are absolute reality, absolute Being. Objects of
sense are absolute unreality, not-being, except in so far as the Ideas
are in them. Whatever reality they have they owe to the Ideas. There
is in Plato's system a principle of absolute not-being which we shall
consider when we come to deal with his Physics. Objects of sense
participate both in the Ideas and in this not-being. They are,
therefore, half way between Being and not-being. They are half real.
Ideas, again, are universal; things of sense are always particular and
individual. The Idea is one, the sense-object is always {192} a
multiplicity. Ideas are outside space and time, things of sense are
both temporal and spatial. The Idea is eternal and immutable;
sense-objects are changeable and in perpetual flux.
As regards the last point, Plato adopts the view of Heracleitus that
there is an absolute Becoming, and he identifies it with the world of
sense, which contains nothing stable and permanent, but is a constant
flow. The Idea always is, and never becomes; the thing of sense always
becomes, and never is. It is for this reason that, in the opinion of
Plato, no knowledge of the world of sense is possible, for one can
have no knowledge of that which changes from moment to moment.
Knowledge is only possible if its subject stands fixed before the
mind, is permanent and changeless. The only knowledge, then, is
knowledge of the Ideas.
This may seem, at first sight, a very singular doctrine. That there
can be no knowledge of sense-objects would, it might seem to us
moderns, involve the denial that modern physical science, with all its
exactitude and accumulated knowledge, is knowledge at all. And surely,
though all earthly things arise and pass away, many of them last long
enough to admit of knowledge. Surely the mountains are sufficiently
permanent to allow us to know something of them. They have relative,
though not absolute, permanence. This criticism is partly justified.
Plato did underestimate the value of physical knowledge. But for the
most part, the criticism is a misunderstanding. By the world of sense
Plato means bare sensation with no rational element in it. Now
physical science has not such crude sensation for its object. Its
objects are rationalized sensations. {193} If, in Plato's manner, we
think only of pure sensation, then it is true that it is nothing but a
constant flux without stability; and knowledge of it is impossible.
The mountains are comparatively permanent. But our sensation of the
mountains is perpetually changing. Every change of light, every cloud
that passes over the sun, changes the colours and the shades. Every
time we move from one situation to another, the mountain appears a
different shape. The permanence of the mountain itself is due to the
fact that all these varying sensations are identified as sensations of
one and the same object. The idea of identity is involved here, and it
is, as it were, a thread upon which these fleeting sensations are
strung. But the idea of identity cannot be obtained from the senses.
It is introduced into things by reason. Hence knowledge of this
permanent mountain is only possible through the exercise of reason. In
Plato's language, all we can know of the mountain is the Ideas in
which it participates. To revert to a previous example, even the
knowledge "this paper is white" involves the activity of intellect,
and is impossible through sensation alone. Bare sensation is a flow,
of which no knowledge is possible.
Aristotle observes that Plato's theory of Ideas has three sources, the
teachings of the Eleatics, of Heracleitus, and of Socrates. From
Heracleitus, Plato took the notion of a sphere of Becoming, and it
appears in his system as the world of sense. From the Eleatics he took
the idea of a sphere of absolute Being. From Socrates he took the
doctrine of concepts, and proceeded to identify the Eleatic Being with
the Socratic concepts. This gives him his theory of Ideas.
{194}
Sense objects, so far as they are knowable, that is so far as they are
more than bare sensations, are so only because the Idea resides in
them. And this yields the clue to Plato's teaching regarding the
relation of sense objects to the Ideas. The Ideas are, in the first
place the cause, that is to say, the ground (not the mechanical cause)
of sense-objects. The Ideas are the absolute reality by which
individual things must be explained. The being of things flows into
them from the Ideas. They are "copies," "imitations," of the Ideas. In
so far as they resemble the Idea, they are real; in so far as they
differ from it, they are unreal. In general, sense objects are, in
Plato's opinion, only very dim, poor and imperfect copies of the
Ideas. They are mere shadows, and half-realities. Another expression
frequently used by Plato to express this relationship is that of
"participation." Things participate in the Ideas. White objects
participate in the one whiteness, beautiful objects, in the one
beauty. In this way beauty itself is the cause or explanation of
beautiful objects, and so of all other Ideas. The Ideas are thus both
transcendent and immanent; immanent in so far as they reside in the
things of sense, transcendent inasmuch as they have a reality of their
own apart from the objects of sense which participate in them. The
Idea of man would still be real even if all men were destroyed, and it
was real before any man existed, if there ever was such a time. For
the Ideas, being timeless, cannot be real now and not then.
Of what kinds of things are there Ideas? That there are moral Ideas,
such as Justice, Goodness, and Beauty, Ideas of corporeal things, such
as horse, man, tree, star, river, and Ideas of qualities, such as
whiteness, heaviness, {195} sweetness, we have already seen. But there
are Ideas not only of natural corporeal objects, but likewise of
manufactured articles; there are Ideas of beds, tables, clothes. And
there are Ideas not only of exalted moral entities, such as Beauty and
Justice. There are also the Ideal Ugliness, and the Ideal Injustice.
There are even Ideas of the positively nauseating, such as hair,
filth, and dirt. This is asserted in the "Parmenides." In that
dialogue Plato's teaching is put into the mouth of Parmenides. He
questions the young Socrates whether there are Ideas of hair, filth,
and dirt. Socrates denies that there can be Ideas of such base things.
But Parmenides corrects him, and tells him that, when he has attained
the highest philosophy, he will no longer despise such things.
Moreover, these Ideas of base things are just as much perfection in
their kind as Beauty and Goodness are in theirs. In general, the
principle is that there must be an Idea wherever a concept can be
formed; that is, wherever there is a class of many things called by
one name.
We saw, in treating of the Eleatics, that for them the absolute Being
contained no not-being, and the absolute One no multiplicity. And it
was just because they denied all not-being and multiplicity of the
absolute reality that they were unable to explain the world of
existence, and were forced to deny it altogether. The same problem
arises for Plato. Is Being absolutely excludent of not-being? Is the
Absolute an abstract One, utterly exclusive of the many? Is his
philosophy a pure monism? Is it a pluralism? Or is it a combination of
the two? These questions are discussed in the "Sophist" and the
"Parmenides."
{196}
Plato investigates the relations of the One and the many, Being and
not-being, quite in the abstract. He decides the principles involved,
and leaves it to the reader to apply them to the theory of Ideas.
Whether the Absolute is one or many, Being or not-being, can be
decided independently of any particular theory of the nature of the
Absolute, and therefore independently of Plato's own theory, which was
that the Absolute consists of Ideas. Plato does not accept the Eleatic
abstraction. The One cannot be simply one, for every unity must
necessarily be a multiplicity. The many and the One are correlative
ideas which involve each other. Neither is thinkable without the
other. A One which is not many is as absurd an abstraction as a whole
which has no parts. For the One can only be defined as that which is
not many, and the many can only be defined as the not-one. The One is
unthinkable except as standing out against a background of the many.
The idea of the One therefore involves the idea of the many, and
cannot be thought without it. Moreover, an abstract One is unthinkable
and unknowable, because all thought and knowledge consist in applying
predicates to subjects, and all predication involves the duality of
its subject.
Consider the simplest affirmation that can be made about the One,
namely, "The One is." Here we have two things, "the One," and "is,"
that is to say, being. The proposition means that the One is Being.
Hence the One is two. Firstly, it is itself, "One." Secondly, it is
"Being," and the proposition affirms that these two things are one.
Similarly with any other predicate we apply to the One. Whatever we
say of it involves its duality. Thus we find that all systems of
thought which {197} postulate an abstract unity as ultimate reality,
such as Eleaticism, Hinduism, and the system of Spinoza, attempt to
avoid the difficulty by saying nothing positive about the One. They
apply to it only negative predicates, which tell us not what it is,
but what it is not. Thus the Hindus speak of Brahman as form_less_,
_im_mutable, _im_perishable, _un_moved, _un_created. But this, of course,
is a futile expedient. In the first place, even a negative predicate
involves the duality of the subject. And, in the second place, a
negative predicate is always, by implication, a positive one. You
cannot have a negative without a positive. To deny one thing is to
affirm its opposite. To deny motion of the One, by calling it the
unmoved, is to affirm rest of it. Thus a One which is not also a many
is unthinkable. Similarly, the idea of the many is inconceivable
without the idea of the One. For the many is many ones. Hence the One
and the many cannot be separated in the Eleatic manner. Every unity
must be a unity of the many. And every many is _ipso facto_ a unity,
since we think the many in one idea, and, if we did not, we should not
even know that it is a many. The Absolute must therefore be neither an
abstract One, nor an abstract many. It must be a many in one.
Similarly, Being cannot totally exclude not-being. They are, just as
much as the One and the many, correlatives, which mutually involve
each other. The being of anything is the not-being of its opposite.
The being of light is the not-being of darkness. All being, therefore,
has not-being in it.
Let us apply these principles to the theory of Ideas. The absolute
reality, the world of Ideas, is many, since {198} there are many
Ideas, but it is one, because the Ideas are not isolated units, but
members of a single organized system. There is, in fact, a hierarchy
of Ideas. Just as the one Idea presides over many individual things of
which it is the common element, so one higher Idea presides over many
lower Ideas, and is the common element in them. And over this higher
Idea, together with many others, a still higher Idea will rule. For
example, the Ideas of whiteness, redness, blueness, are all subsumed
under the one Idea of colour. The Ideas of sweetness and bitterness
come under the one Idea of taste. But the Ideas of colour and taste
themselves stand under the still higher Idea of quality. In this way,
the Ideas form, as it were, a pyramid, and to this pyramid there must
be an apex. There must be one highest Idea, which is supreme over all
the others. This Idea will be the one final and absolutely real Being
which is the ultimate ground, of itself, of the other Ideas, and of
the entire universe. This Idea is, Plato tells us, the Idea of the
Good. We have seen that the world of Ideas is many, and we now see
that it is one. For it is one single system culminating in one supreme
Idea, which is the highest expression of its unity. Moreover, each
separate Idea is, in the same way, a many in one. It is one in regard
to itself. That is to say, if we ignore its relations to other Ideas,
it is, in itself, single. But as it has also many relations to other
Ideas, it is, in this way, a multiplicity.
Every Idea is likewise a Being which contains not-being. For each Idea
combines with some Ideas and not with others. Thus the Idea of
corporeal body combines both with the Idea of rest and that of motion.
{199} But the Ideas of rest and motion will not combine with each
other. The Idea of rest, therefore, is Being in regard to itself,
not-being in regard to the Idea of motion, for the being of rest is
the not-being of motion. All Ideas are Being in regard to themselves,
and not-being in regard to all those other Ideas with which they do
not combine.
In this way there arises a science of Ideas which is called dialectic.
This word is sometimes used as identical with the phrase, "theory of
Ideas." But it is also used, in a narrower sense, to mean the science
which has to do with the knowledge of which Ideas will combine and
which not. Dialectic is the correct joining and disjoining of Ideas.
It is the knowledge of the relations of all the Ideas to each other.
The attainment of this knowledge is, in Plato's opinion, the chief
problem of philosophy. To know all the Ideas, each in itself and in
its relations to other Ideas, is the supreme task. This involves two
steps. The first is the formation of concepts. Its object is to know
each Idea separately, and its procedure is by inductive reason to find
the common element in which the many individual objects participate.
The second step consists in the knowledge of the inter-relation of
Ideas, and involves the two processes of classification and division.
Classification and division both have for their object to arrange the
lower Ideas under the proper higher Ideas, but they do this in
opposite ways. One may begin with the lower Ideas, such as redness,
whiteness, etc., and range them under their higher Idea, that of
colour. This is classification. Or one may begin with the higher Idea,
colour, and divide it into the lower Ideas, red, white, {200} etc.
Classification proceeds from below upwards. Division proceeds from
above downwards. Most of the examples of division which Plato gives
are divisions by dichotomy. We may either divide colour straight away
into red, blue, white, etc.; or we may divide each class into two
sub-classes. Thus colour will be divided into red and not-red, not-red
into white and not-white, not-white into blue and not-blue, and so on.
This latter process is division by dichotomy, and Plato prefers it
because, though it is tedious, it is very exhaustive and systematic.
Plato's actual performance of the supreme task of dialectic, the
classification and arrangement of all Ideas, is not great. He has made
no attempt to complete it. All he has done is to give us numerous
examples. And this is, in reality, all that can be expected, for the
number of Ideas is obviously infinite, and therefore the task of
arranging them cannot be completed. There is, however, one important
defect in the dialectic, which Plato ought certainly to have remedied.
The supreme Idea, he tells us, is the Good. This, as being the
ultimate reality, is the ground of all other Ideas. Plato ought
therefore to have derived all other Ideas from it, but this he has not
done. He merely asserts, in a more or less dogmatic way, that the Idea
of the Good is the highest, but does nothing to connect it with the
other Ideas. It is easy to see, however, why he made this assertion.
It is, in fact, a necessary logical outcome of his system. For every
Idea is perfection in its kind. All the Ideas have perfection in
common. And just as the one beauty is the Idea which presides over all
beautiful things, so the one perfection must be the supreme Idea which
presides {201} over all the perfect Ideas. The supreme Idea,
therefore, must be perfection itself, that is to say, the Idea of the
Good. On the other hand it might, with equal force, be argued that
since all the Ideas are substances, therefore the highest Idea is the
Idea of substance. All that can be said is that Plato has left these
matters in obscurity, and has merely asserted that the highest Idea is
the Good.
Consideration of the Idea of the Good leads us naturally to enquire
how far Plato's system is teleological in character. A little
consideration will show that it is out and out teleological. We can
see this both by studying the many lower Ideas, and the one supreme
Idea. Each Idea is perfection of its kind. And each Idea is the ground
of the existence of the individual objects which come under it. Thus
the explanation of white objects is the perfect whiteness, of
beautiful objects the perfect beauty. Or we may take as our example
the Idea of the State which Plato describes in the "Republic." The
ordinary view is that Plato was describing a State which was the
invention of his own fancy, and is therefore to be regarded as
entirely unreal. This is completely to misunderstand Plato. So far was
he from thinking the ideal State unreal, that he regarded it, on the
contrary, as the only real State. All existent States, such as the
Athenian or the Spartan, are unreal in so far as they differ from the
ideal State. And moreover, this one reality, the ideal State, is the
ground of the existence of all actual States. They owe their existence
to its reality. Their existence can only be explained by it. Now since
the ideal State is not yet reached in fact, but is the perfect State
towards which all actual States tend, it is clear that we have here
{202} a teleological principle. The real explanation of the State is
not to be found in its beginnings in history, in an original contract,
or in biological necessities, but in its end, the final or perfect
State. Or, if we prefer to put it so; the true beginning is the end.
The end must be in the beginning, potentially and ideally, otherwise
it could never begin: It is the same with all other things. Man is
explained by the ideal man, the perfect man; white things by the
perfect whiteness, and so on. Everything is explained by its end, and
not by its beginning. Things are not explained by mechanical causes,
but by reasons.
And the teleology of Plato culminates in the Idea of the Good. That
Idea is the final explanation of all other Ideas, and of the entire
universe. And to place the final ground of all things in perfection
itself means that the universe arises out of that perfect end towards
which all things move.
Another matter which requires elucidation here is the place which the
conception of God holds in Plato's system. He frequently uses the word
God both in the singular and the plural, and seems to slip with
remarkable ease from the monotheistic to the polytheistic manner of
speaking. In addition to the many gods, we have frequent reference to
the one supreme Creator, controller, and ruler of the world, who is
further conceived as a Being providentially watching over the lives of
men. But in what relation does this supreme God stand to the Ideas,
and especially to the Idea of the Good? If God is separate from the
highest Idea, then, as Zeller points out, [Footnote 13] only three
relations are possible, all of which are {203} equally objectionable.
Firstly, God may be the cause or ground of the Idea of the Good. But
this destroys the substantiality of the Idea, and indeed, destroys
Plato's whole system. The very essence of his philosophy is that the
Idea is the ultimate reality, which is self-existent, and owes its
being to nothing else. But this theory makes it a mere creature of
God, dependent on Him for its existence. Secondly, God may owe His
being to the Idea. The Idea may be the ground of God's existence as it
is the ground of all else in the universe. But this theory does
violence to the idea of God, turning Him into a mere derivative
existence, and, in fact, into an appearance. Thirdly, God and the Idea
may be co-ordinate in the system as equally primordial independent
ultimate realities. But this means that Plato has given two mutually
inconsistent accounts of the ultimate reality, or, if not, that his
system is a hopeless dualism. As none of these theories can be
maintained, it must be supposed that God is identical with the Idea of
the Good, and we find certain expressions in the "Philebus" which seem
clearly to assert this. But in that case God is not a personal God at
all, since the Idea is not a person. The word God, if used in this
way, is merely a figurative term for the Idea. And this is the most
probable theory, if we reflect that there is in fact no room for a
personal God in a system which places all reality in the Idea, and
that to introduce such a conception threatens to break up the whole
system. Plato probably found it useful to take the popular conceptions
about the personality of God or the gods and use them, in mythical
fashion, to express his Ideas. Those parts of Plato which speak of
God, and the governance of God, {204} are to be interpreted on the
same principles as the other Platonic myths.
[Footnote 13: _Plato and the Older Academy_, chap. vi.]
Before closing our discussion of dialectic, it may be well to consider
what place it occupies in the life of man, and what importance is
attached to it. Here Plato's answer is emphatic. Dialectic is the
crown of knowledge, and knowledge is the crown of life. All other
spiritual activities have value only in so far as they lead up to the
knowledge of the Idea. All other subjects of intellectual study are
merely preparatory to the study of philosophy. The special sciences
have no value in themselves, but they have value inasmuch as their
definitions and classifications form a preparation for the knowledge
of Ideas. Mathematics is important because it is a stepping-stone from
the world of sense to the Ideas. Its objects, namely, numbers and
geometrical figures, resemble the Ideas in so far as they are
immutable, and they resemble sense-objects in so far as they are in
space or time. In the educational curriculum of Plato, philosophy
comes last. Not everyone may study it. And none may study it till he
has been through all the preparatory stages of education, which form a
rigorous discipline of the mind before it finally enters upon
dialectic. Thus all knowledge ends in dialectic, and that life has not
attained its end which falls short of philosophy.
Perhaps the most striking illustration of the subordination of all
spiritual activities to philosophy is to be found in the doctrine of
Eros, or Love. The phrase "platonic love" is on the lips of many, but,
as a rule, something very different from Plato's own doctrine is
meant. According to him, love is always concerned with beauty, and his
teaching on the subject is expounded {205} chiefly in the "Symposium,"
He believed that before birth the soul dwelt disembodied in the pure
contemplation of the world of Ideas. Sinking down into a body,
becoming immersed in the world of sense, it forgets the Ideas. The
sight of a beautiful object reminds it of that one Idea of beauty of
which the object is a copy. This accounts for the mystic rapture, the
emotion, the joy, with which we greet the sight of the beautiful.
Since Plato had expressly declared that there are Ideas of the ugly as
well as of the beautiful, that there are Ideas, for example, of hair,
filth, and dirt, and since these Ideas are just as divine and perfect
as the Idea of the beautiful, we ought, on this theory, to greet the
ugly, the filthy, and the nauseating, with a ravishment of joy similar
to that which we experience in the presence of beauty. Why this is not
the case Plato omitted to explain. However, having learned to love the
one beautiful object, the soul passes on to the love of others. Then
it perceives that it is the same beauty which reveals itself in all
these. It passes from the love of beautiful forms to the love of
beautiful souls, and from that to the love of beautiful sciences. It
ceases to be attached to the many objects, as such, that is to say, to
the sensuous envelopes of the Idea of beauty. Love passes into the
knowledge of the Idea of beauty itself, and from this to the knowledge
of the world of Ideas in general. It passes in fact into philosophy.
In this development there are two points which we cannot fail to note.
In the first place, emotional love is explained as being simply the
blind groping of reason towards the Idea. It is reason which has not
yet recognized itself as such. It appears, therefore, in the {206}
guise of feeling. Secondly, the later progress of the soul's love is
simply the gradual recognition of itself by reason. When the soul
perceives that the beauty in all objects is the same, that it is the
common element amid the many, this is nothing but the process of
inductive reasoning. And this development ends at last in the complete
rational cognition of the world of Ideas, in a word, philosophy. Love
is but an instinctive reason. The animal has no feeling of the
beautiful, just because it has no reason. Love of the beautiful is
founded upon the nature of man, not as a percipient or feeling being,
but as a rational being. And it must end in the complete recognition
of reason by itself, not in the feeling and intuition, but in the
rational comprehension, of the Idea.
One can imagine what Plato's answer would be to the sort of vulgarians
and philistines who want to know what the use of philosophy is, and in
what way it is "practical." To answer such a question is for Plato
impossible, because the question itself is illegitimate. For a thing
to have a use involves that it is a means towards an end. Fire has
use, because it may be made a means towards the cooking of food. Money
is useful, because it is a means to the acquisition of goods. That
which is an end in itself, and not a means towards any further end,
cannot possibly have any use. To suggest that philosophy ought to have
use is, therefore, to put the cart before the horse, to invert the
whole scale of values. It suggests that philosophy is a means towards
some further end, instead of being the absolute end to which all other
things are means. Philosophy is not _for_ anything. Everything else is
_for_ it. And, if this seems an exaggerated or unpractical view, we may
at least {207} remember that this is the view taken by the religious
consciousness of man. Religion makes the supreme end of life the
knowledge of, and communion with, God. God is for religion what the
Idea is for philosophy. God is a figurative name for the Idea. To
place the end of life in the knowledge of the Absolute, or the Idea,
is therefore the teaching both of philosophy and religion.
4. Physics, or the Theory of Existence.
Dialectic is the theory of reality, physics the theory of existence,
dialectic of that which lies behind things as their ground, physics of
the things which are thus grounded. That is to say, physics is
concerned with phenomena and appearances, things which exist in space
and time, as opposed to the timeless and non-spatial Ideas. Things of
this kind are both corporeal and incorporeal. Physics falls therefore
into two parts, the doctrine of the outward corporeality, the world,
with its incorporeal essence, the World-Soul, and the doctrine of the
incorporeal soul of man.
_(a) The Doctrine of the World_.
If, in the dialectic, Plato has given an account of the nature of the
first principle and ground of all things, the problem now arises of
explaining how the actual universe of things arises out of that
ground, how it is derived from the first principle. In other words,
the Ideas being the absolute reality, how does the world of sense,
and, in general, the existent universe, arise out of the Ideas? Faced
with this problem, the system of Plato broke down. The things of sense
are, we are told, "copies" or "imitations" of the Ideas. {208} They
"participate" in the Ideas. So far, so good. But why should there be
any copies of the Ideas? Why should the Ideas give rise to copies of
themselves, and how is the production of these copies effected? To
these questions Plato has no answer, and he therefore has recourse to
the use of myths. Poetic description here takes the place of
scientific explanation.
This poetic description of the origin of the world is to be found in
the "Timaeus." We have seen that the Ideas are absolute Being, and
that things of sense are half real and half unreal. They are partly
real because they participate in Being. They are partly unreal because
they participate in not-being. There must be, therefore, a principle
of absolute not-being. This, in Plato's opinion, is matter. Things of
sense are copies of the Ideas fashioned out of, or stamped upon,
matter. But Plato does not understand by matter what we, in modern
times, understand by it. Matter, in our sense, is always some
particular kind of matter. It is brass, or wood, or iron, or stone. It
is matter which has determinate character and quality. But the
possession of specific character means that it is matter with the copy
of Ideas already stamped upon it. Since iron exists in great
quantities in the world, and there is a common element in all the
various pieces of iron, by virtue of which all are classed together,
there must be a concept of iron. There is, therefore, an Idea of iron
in the world of Ideas. And the iron which we find in the earth must be
matter which is already formed into a copy of this Idea. It
participates in the Idea of iron. The same remarks apply to any other
particular kind of matter. In fact, all form, all the specific
characters and {209} features of matter, as we know it, are due to the
operation of the Ideas. Hence matter as it is in itself, before the
image of the Ideas is stamped upon it, must be absolutely without
quality, featureless, formless. But to be absolutely without any
quality is to be simply nothing at all. This matter is, therefore, as
Plato says, absolute not-being. Zeller conjectures, probably rightly,
that what Plato meant was simply empty space. [Footnote 14] Empty
space is an existent not-being, and it is totally indeterminate and
formless. It accords with this view that Plato adopted the Pythagorean
tenet that the differential qualities of material substances are due
to their smallest particles being regular geometrical figures limited
out of the unlimited, that is, out of space. Thus earth is composed of
cubes. That is to say, empty space when bound into cubes (the limiting
of the unlimited) becomes earth. The smallest particles of fire are
_tetrahedra_, of air _octahedra_, of water _icosahedra_.
[Footnote 14: _Plato and the Older Academy_, chap. vii. ]
We have, then, on the one hand, the world of Ideas, on the other,
matter, an absolutely formless, chaotic, mass. By impressing the
images of the Ideas upon this mass, "things" arise, that is to say,
the specific objects of sense. They thus participate both in Being and
in not-being. But how is this mixing of Being and not-being brought
about? How do the Ideas come to have their images stamped upon matter?
It is at this point that we enter upon the region of myth. Up to this
point Plato is certainly to be taken literally. He of course believed
in the reality of the world of Ideas, and he no doubt also believed in
his principle of matter. And he thought that the objects of sense are
to be {210} explained as copies of the Ideas impressed upon matter.
But now, with the problem how this copying is brought about, Plato
leaves the method of scientific explanation behind. If the Ideas are
the absolute ground of all things, then the copying process must be
done by the Ideas themselves. They must themselves be made the
principles for the production of things. But this is, for Plato,
impossible. For production involves change. If the Ideas produce
things out of themselves, the Ideas must in the process undergo
change. But Plato has declared them to be absolutely unchangeable, and
to be thus immutable is to be sterile. Hence the Ideas have within
themselves no principle for the production of things, and the
scientific explanation of things by this means becomes impossible.
Hence there is nothing for it but to have recourse to myth. Plato can
only imagine that things are produced by a world-former, or designer,
who, like a human artist, fashions the plastic matter into images of
the Ideas.
God, the Creator, the world-designer, finds beside him, on the one
hand, the Ideas, on the other, formless matter. First, he creates the
World-Soul. This is incorporeal, but occupies space. He spreads it out
like a huge net in empty space. He bisects it, and bends the two
halves into an inner and an outer circle, these circles being destined
to become the spheres of the planets and the stars respectively. He
takes matter and binds it into the four elements, and these elements
he builds into the empty framework of the World-Soul. When this is
done, the creation of the universe is complete. The rest of the
"Timaeus" is occupied with the details of Plato's ideas of astronomy
and physical {211} science. These are mostly worthless and tedious,
and we need not pursue them here. But we may mention that Plato, of
course, regarded the earth as the centre of the world. The stars,
which are divine beings, revolve around it. They necessarily move in
circles, because the circle is the perfect figure. The stars, being
divine, are governed solely by reason, and their movement must
therefore be circular, because a circular motion is the motion of
reason.
The above account of the origin of the world is merely myth, and Plato
knows that it is myth. What he apparently did believe in, however, was
the existence of the World-Soul, and a few words upon this subject are
necessary. The soul, in Plato's system, is the mediator between the
world of Ideas and the world of sense. Like the former, it is
incorporeal and immortal. Like the latter, it occupies space. Plato
thought that there must be a soul in the world to account for the
rational behaviour of things, and to explain motion. The reason which
governs and directs the world dwells in the World-Soul. And the
World-Soul is the cause of motion in the outer universe, just as the
human soul is the cause of the motions of the human body. The cosmos
is a living being.
_(b) The Doctrine of the Human Soul_.
The human soul is similar in kind to the World-Soul. It is the cause
of the body's movements, and in it the human reason dwells. It has
affinities both with the world of Ideas and the world of sense. It is
divided into two parts, of which one part is again subdivided into
two. The highest part is reason, which is {212} that part of the soul
which apprehends the Ideas. It is simple and indivisible. Now all
destruction of things means the sundering of their parts. But the
rational part of the soul, being simple, has no parts. Therefore it is
indestructible and immortal. The irrational part of the soul is
mortal, and is subdivided into a noble and an ignoble half. To the
noble half belong courage, love of honour, and in general the nobler
emotions. To the ignoble portion belong the sensuous appetites. The
noble half has a certain affinity with reason, in that it has an
instinct for what is noble and great. Nevertheless, this is mere
instinct, and is not rational. The seat of reason is the head, of the
noble half of the lower soul, the breast, of the ignoble half, the
lower part of the body. Man alone possesses the three parts of the
soul. Animals possess the two lower parts, plants only the appetitive
soul. What distinguishes man from the lower orders of creation is thus
that he alone possesses reason.
Plato connects the doctrine of the immortality of the rational soul
with the theory of Ideas by means of the doctrines of recollection and
transmigration. According to the former doctrine, all knowledge is
recollection of what was experienced by the soul in its disembodied
state before birth. It must carefully be noted, however, that the word
knowledge is here used in the special and restricted sense of Plato.
Not everything that we should call knowledge is recollection. The
sensuous element in my perception that this paper is white is not
recollection, since, as being merely sensuous, it is not, in Plato's
opinion, to be called knowledge. Here, as elsewhere, he confines the
term {213} to rational knowledge, that is to say, knowledge of the
Ideas, though it is doubtful whether he is wholly consistent with
himself in the matter, especially in regard to mathematical knowledge.
It must also be noted that this doctrine has nothing in common with
the Oriental doctrine of the memory of our past lives upon the earth.
An example of this is found in the Buddhist Jàtakas, where the Buddha
relates from memory many things that happened to him in the body in
his previous births. Plato's doctrine is quite different. It refers
only to recollection of the experiences of the soul in its disembodied
state in the world of Ideas.
The reasons assigned by Plato for believing in this doctrine may be
reduced to two. Firstly, knowledge of the Ideas cannot be derived from
the senses, because the Idea is never pure in its sensuous
manifestation, but always mixed. The one beauty, for example, is only
found in experience mixed with the ugly. The second reason is more
striking. And, if the doctrine of recollection is itself fantastic,
this, the chief reason upon which Plato bases it, is interesting and
important. He pointed out that mathematical knowledge seems to be
innate in the mind. It is neither imparted to us by instruction, nor
is it gained from experience. Plato, in fact, came within an ace of
discovering what, in modern times, is called the distinction between
necessary and contingent knowledge, a distinction which was made by
Kant the basis of most far-reaching developments in philosophy. The
character of necessity attaches to rational knowledge, but not to
sensuous. To explain this distinction, we may take as our example of
rational knowledge such a proposition as that two {214} and two make
four. This does not mean merely that, as a matter of fact, every two
objects and every other two objects, with which we have tried the
experiment, make four. It is not merely a fact, it is a necessity. It
is not merely that two and two do make four, but that they must make
four. It is inconceivable that they should not. We have not got to go
and see whether, in each new case, they do so. We know beforehand that
they will, because they must. It is quite otherwise with such a
proposition as, "gold is yellow." There is no necessity about it. It
is merely a fact. For all anybody can see to the contrary it might
just as well be blue. There is nothing inconceivable about its being
blue, as there is about two and two making five. Of course, that gold
is yellow is no doubt a mechanical necessity, that is, it is
determined by causes, and in that sense could not be otherwise. But it
is not a logical necessity. It is not a logical contradiction to
imagine blue gold, as it would be to imagine two and two making five.
Any other proposition in mathematics possesses the same necessity.
That the angles at the base of an isosceles triangle are equal is a
necessary proposition. It could not be otherwise without
contradiction. Its opposite is unthinkable. But that Socrates is
standing is not a necessary truth. He might just as well be sitting.
Since a mathematical proposition is necessarily true, its truth is
known without verification by experience. Having proved the
proposition about the isosceles triangle, we do not go about measuring
the angles of triangular objects to make sure there is no exception.
We know it without any experience at all. And if we {215} were
sufficiently clever, we might even evolve mathematical knowledge out
of the resources of our own minds, without its being told us by any
teacher. That Caesar was stabbed by Brutus is a fact which no amount
of cleverness could ever reveal to me. This information I can only get
by being told it. But that the base angles of an isosceles triangle
are equal I could discover by merely thinking about it. The
proposition about Brutus is not a necessary proposition. It might be
otherwise. And therefore I must be told whether it is true or not. But
the proposition about the isosceles triangle is necessary, and
therefore I can see that it must be true without being told.
Now Plato did not clearly make this distinction between necessary and
non-necessary knowledge. But what he did perceive was that
mathematical knowledge can be known without either experience or
instruction. Kant afterwards gave a less fantastic explanation of
these facts. But Plato concluded that such knowledge must be already
present in the mind at birth. It must be recollected from a previous
existence. It might be answered that, though this kind of knowledge is
not gained from the experience of the senses, it may be gained from
teaching. It may be imparted by another mind. We have to teach
children mathematics, which we should not have to do if it were
already in their minds. But Plato's answer is that when the teacher
explains a geometrical theorem to the child, directly the child
understands what is meant, he assents. He sees it for himself. But if
the teacher explains that Lisbon is on the Tagus, the child cannot see
that this is true for himself. He must either believe the word {216}
of the teacher, or he must go and see. In this case, therefore, the
knowledge is really imparted from one mind to another. The teacher
transfers to the child knowledge which the child does not possess. But
the mathematical theorem is already present in the child's mind, and
the process of teaching merely consists in making him see what he
already potentially knows. He has only to look into his own mind to
find it. This is what we mean by saying that the child sees it for
himself.
In the "Meno" Plato attempts to give an experimental proof of the
doctrine of recollection. Socrates is represented as talking to a
slave-boy, who admittedly has no education in mathematics, and barely
knows what a square is. By dint of skilful questioning Socrates
elicits from the boy's mind a theorem about the properties of the
square. The point of the argument is that Socrates tells him nothing
at all. He imparts no information. He only asks questions. The boy's
knowledge of the theorem, therefore, is not due to the teaching of
Socrates, nor is it due to experience. It can only be recollection.
But if knowledge is recollection, it may be asked, why is it that we
do not remember at once? Why is the tedious process of education in
mathematics necessary? Because the soul, descending from the world of
Ideas into the body, has its knowledge dulled and almost blotted out
by its immersion in the sensuous. It has forgotten, or it has only the
dimmest and faintest recollection. It has to be reminded, and it takes
a great effort to bring the half-lost ideas back to the mind. This
process of being reminded is education.
With this, of course, is connected the doctrine of {217}
transmigration, which Plato took, no doubt, from the Pythagoreans.
Most of the details of Plato's doctrine of transmigration are mere
myth. Plato does not mean them seriously, as is shown by the fact that
he gives quite different and inconsistent accounts of these details in
different dialogues. What, in all probability, he did believe,
however, may be summarized as follows. The soul is pre-existent as
well as immortal. Its natural home is the world of Ideas, where at
first it existed, without a body, in the pure and blissful
contemplation of Ideas. But because it has affinities with the world
of sense, it sinks down into a body. After death, if a man has lived a
good life, and especially if he has cultivated the knowledge of Ideas,
philosophy, the soul returns to its blissful abode in the world of
Ideas, till, after a long period it again returns to earth in a body.
Those who do evil suffer after death severe penalties, and are then
reincarnated in the body of some being lower than themselves. A man
may become a woman. Men may even, if their lives have been utterly
sensual, pass into the bodies of animals.
5. Ethics
_(a) The Ethics of the Individual_
Just as Plato's theory of knowledge begins with a negative portion,
designed to refute false theories of what truth is, so does his theory
of morals begin with a negative portion, intended to refute false
theories of what virtue is. These two negative departments of Plato's
philosophy correspond in every way. As he was then engaged in showing
that knowledge is not perception, as Protagoras thought, so he now
urges that {218} virtue is not the same as pleasure. And as knowledge
is not mere right opinion, neither is virtue mere right action. The
propositions that knowledge is perception, and that virtue is
pleasure, are indeed only the same principle applied to different
spheres of thought. For the Sophists whatever appeared true to the
individual was true for that individual. This is the same as saying
that knowledge is perception. For the Sophists, again, whatever
appeared right to the individual was right for that individual. This
is the same as saying that it is right for each man to do whatever he
pleases. Virtue is defined as the pleasure of the individual. This
consequence of the Sophistic principles was drawn both by many of the
Sophists themselves, and later by the Cyrenaics.
As these two propositions are thus in fact only one principle, what
Plato has said in refutation of the former provides also his
refutation of the latter. The theory that virtue is pleasure has the
same destructive influence upon morals as the theory that knowledge is
perception had upon truth. We may thus shortly summarize Plato's
arguments.
(1) As the Sophistic theory of truth destroys the objectivity of
truth, so the doctrine that virtue is the pleasure of the individual
destroys the objectivity of the good. Nothing is good in itself.
Things are only good for me or for you. There results an absolute
moral relativity, in which the idea of an objective standard of
goodness totally disappears.
(2) This theory destroys the distinction between good and evil. Since
the good is whatever the individual pleases, and since the pleasure of
one individual is the {219} displeasure of another, the same thing is
both good and evil at the same time, good for one person and evil for
another. Good and evil are therefore not distinct. They are the same.
(3) Pleasure is the satisfaction of our desires. Desires are merely
feelings. This theory, therefore, founds morality upon feeling. But an
objective morality cannot be founded upon what is peculiar to
individuals. If the moral code is to be a law binding upon all men, it
can only be founded upon that which is common to all men, the
universal reason.
(4) The end of moral activity must fall within, and not outside, the
moral act itself. Morality must have an intrinsic, not a merely
extrinsic, value. We must not do right for the sake of something else.
We must do right because it is right, and thus make virtue an end in
itself. But the Sophistic theory places the end of morality outside
morality. We are to do right, not for its own sake, but for the sake
of pleasure. Morality is thus not an end in itself, but merely a means
towards a further end.
Virtue, therefore, is not pleasure, any more than knowledge is
perception. Likewise, just as knowledge is not right opinion, so
virtue is not right action. Right opinion may be held upon wrong
grounds, and right action may be performed on wrong grounds. For true
virtue we must not only know what is right, but why it is right. True
virtue is thus right action proceeding from a rational comprehension
of true values. Hence there arises in Plato's philosophy a distinction
between philosophic virtue and customary virtue. Philosophic virtue is
founded upon reason, and understands the {220} principle on which it
acts. It is, in fact, action governed by principles. Customary virtue
is right action proceeding from any other grounds, such as custom,
habit, tradition, good impulses, benevolent feelings, instinctive
goodness. Men do right merely because other people do it, because it
is customary, and they do it without understanding the reasons for it.
This is the virtue of the ordinary honest citizen, the "respectable"
person. It is the virtue of bees and ants, who act as if rationally,
but without any understanding of what they are doing. And Plato
observes--no doubt with an intentional spice of humour--that such
people may in the next life find themselves born as bees and ants.
Plato denies philosophic virtue not only to the masses of men, but
even to the best statesmen and politicians of Greece.
As true virtue is virtue which knows at what it is aiming, the
knowledge of the nature of the highest aim becomes the chief question
of ethics. What is the end of moral activity? Now we have just seen
that that end must fall within, and not outside, the moral act. The
end of goodness is the good. What, then, is the good? What is the
supreme good, the _summum bonum_?
A note of warning is necessary before we enter upon the details of
this problem. Plato frequently speaks of all moral activity aiming at,
and ending in, happiness. With modern phrases ringing in our ears, we
might easily suppose this to mean that Plato is a utilitarian. The
utilitarianism of Bentham and Mill is distinguished by the fact that
it places the end of morality in happiness. Yet Plato was not a
utilitarian, and would unhesitatingly have condemned the theory of
Mill. He {221} would have found it identical in principle with the
Sophistic doctrine that pleasure is the end of virtue. The only
difference is that, whereas the Sophists identified virtue with the
pleasure of the individual, Mill makes it the pleasure of the
community. That act is right which leads to "the greatest happiness of
the greatest number." In practice, of course, this makes a tremendous
difference. But the principle is equally objectionable because, like
the Sophistic theory, it founds morality upon mere feeling, instead of
upon reason, and because it places the end of morality outside
morality itself. Yet the formula of Mill, that the end of morals is
happiness, seems the same as Plato's formula. What is the difference?
The fact is that what Mill calls happiness Plato would have called
pleasure. Pleasure is the satisfaction of one's desires, whether they
are noble or ignoble. Then what is happiness? It can only be defined
as the general harmonious well-being of life. Only that man is happy
whose soul is in the state it ought to be in, only in fact the just,
the good, and the moral man. Happiness has nothing to do with
pleasure. If you could conceive an absolutely just and upright man,
who was yet weighed down with every possible misery and disaster, in
whose life pleasure had no part, such a man would still be absolutely
happy. Happiness is, therefore, in Plato, merely another name for the
_summum bonum_. In saying that the _summum bonum_ is happiness, Plato
is not telling us anything about it. He is merely giving it a new
name. And we are still left to enquire: what is the _summum bonum_?
what is happiness?
Plato's answer, as indeed his whole ethics, is but {222} an
application of the theory of Ideas. But here we can distinguish two
different and, to some extent, inconsistent strains of thought, which
exist side by side in Plato, and perpetually struggle for the mastery.
Both views depend upon the theory of Ideas. In the first place, the
Idea, in Plato's philosophy, is the sole reality. The object of sense
is unreal, and merely clogs and dims the soul's vision of the Ideas.
Matter is that which obstructs the free activity of the Idea.
Sense-objects hide the Idea from our view. Therefore the world of
sense is wholly evil. True virtue must consist in flying from the
world of sense, in retiring from the affairs of the world, and even
from the beauty of the senses, into the calm of philosophic
contemplation. And if this were all, philosophy, the knowledge of the
Ideas, would be the sole constituent of the _summum bonum_. But it is
possible to regard sense-objects in another light. They are, after
all, copies of the Ideas. They are therefore a manifestation and
revelation of the ideal world. Hence Plato is compelled by this
thought to allow a certain value to the world of sense, its affairs,
and its beauty.
The result of this inconsistency is, at any rate, that Plato remains
broad and human. He does not, on the one hand, preach a purely selfish
retirement into philosophy, or a narrow ascetic ideal. He does not, on
the other hand, adopt a low utilitarian view of life, allowing value
only to that which is "practical." He remains true to the Greek ideal
of life as a harmonious play of all the faculties, in which no one
part of man is over-developed at the expense of the others.
The result is that Plato's _summum bonum_ is not a single {223} end.
It is a compound consisting of four parts. First, and chief of all, is
the knowledge of the Ideas as they are in themselves, philosophy.
Secondly, the contemplation of the Ideas as they reveal themselves in
the world of sense, the love and appreciation of all that is
beautiful, ordered, and harmonious. Thirdly, the cultivation of the
special sciences and arts. And fourthly, indulgence in pure, refined,
and innocent pleasures of the senses, excluding, of course, whatever
is base and evil.
Plato had also a specific doctrine of virtue. As already stated, he
distinguished between philosophic and customary virtue, and attached
absolute value only to the former. He does not, however, deny a
relative value to customary virtue, inasmuch as it is a means towards
true virtue. Plato saw that man cannot rise at one bound to the
pinnacles of rational virtue. He must needs pass through the
preparatory stage of customary virtue. In the man in whom reason is
not yet awakened, good habits and customs must be implanted, in order
that, when reason comes, it may find the ground ready prepared.
Socrates had taught that virtue is one. And Plato in his earlier
writings adopted this view. But later on he came to see that every
faculty of man has its place and its function, and the due performance
of its function is a virtue. He did not, however, surrender the unity
of virtue altogether, but believed that its unity is compatible with
its plurality. There are four cardinal virtues. Three of these
correspond to the three parts of the soul, and the fourth is the unity
of the others. The virtue of reason is wisdom, of the noble half of
{224} the mortal soul courage, of the ignoble appetites, temperance or
self-control, in which the passions allow themselves to be governed by
reason. The fourth virtue, justice, arises from the others. Justice
means proportion and harmony, and accrues to the soul when all three
parts perform their functions and co-operate with each other.
Following Zeller, we may add to this account of the virtues some of
Plato's views upon the details of life. And first, his opinion of
women and marriage. Here Plato does not rise above the level of
ordinary Greek morals. He has nothing specially original to say, but
reflects the opinions of his age. Women he regards as essentially
inferior to men. Moreover, the modern view of woman as the complement
of man, as possessing those special virtues of womanliness, which a
man lacks, is quite alien to Plato. The difference between men and
women is, in his view, not one of kind but only of degree. The only
specific difference between the sexes is the physical difference.
Spiritually they are quite the same, except that woman is inferior.
Hence Plato would not exclude women from the same education which man
receives. He would educate them in exactly the same way, but this
involves the imposition upon them of the same burdens. Even military
duties are not outside the sphere of women.
His views of marriage flow from the same principle. Since woman is not
the complement of man, she is in no special sense fitted to be his
companion. Hence the ideal of spiritual companionship is absent from
Plato's view of marriage, the sole object of which, in his opinion, is
the propagation of children. The natural companion {225} of a man is
not a woman, but another man. The ideal of friendship, therefore,
takes the place of the spiritual ideal of marriage in Plato and,
indeed, among the ancients generally.
Slavery is not denounced by Plato. He takes no trouble to justify it,
because he thinks it so obviously right that it needs no
justification. All that can be said to his credit is that he demands
humane and just, though firm and unsentimental, treatment of slaves.
If in these respects Plato never transcends the Greek view of life, in
one matter at least he does so. The common view of his time was that
one ought to do good to one's friends and evil to one's enemies. This
Plato expressly repudiates. It can never be good, he thinks, to do
evil. One should rather do good to one's enemies, and so convert them
into friends. To return good for evil is no less a Platonic than a
Christian maxim.
_(b) The State_.
We pass from the ethics of individual life to the ethics of the
community. Plato's "Republic" is not an attempt to paint an imaginary
and unreal perfection. Its object is to found politics on the theory
of Ideas by depicting the Idea of the State. This State is, therefore,
not unreal, but the only real State, and its reality is the ground of
the existence of all actually existent States.
We can trace here, too, the same two strains of thought as we found in
considering the ethics of the individual. On the one hand, since the
Idea alone is real, the existent world a mere illusion, the service of
the {226} State cannot be the ideal life for a rational being.
Complete retirement from the world into the sphere of Ideas is a far
nobler end, and the aims of the ordinary politician are, in
comparison, worthless baubles. Though only the philosopher is
competent to rule, yet he will not undertake the business of the
State, except under compulsion. In the political States, as they exist
in the world, the philosopher dwells with his body, but his soul is a
stranger, ignorant of their standards, unmoved by their ambitions. But
the opposite strain of thought is uppermost when we are told that it
is, after all, only in the State, only in his capacity as a citizen
and a social being that the individual can attain perfection. It is
only possible to reconcile these views in one way. If the ideals of
the State and of philosophy seem inconsistent, they must be brought
together by adapting the State to philosophy. We must have a State
founded upon philosophy and reason. Then only can the philosopher
dwell in it with his soul as well as with his body. Then only can
either the individual or the State reach perfection. To found the
State upon reason is the keynote of Plato's politics.
And this gives us, too, the clue to the problem, what is the end of
the State? Why should there be a State at all? This does not mean, how
has the State arisen in history? We are not in search of the cause,
but of the reason, or end, of the State. The end of all life is
wisdom, virtue, and knowledge. The unassisted individual cannot reach
these ends. It is only by the State that they can be brought down from
heaven to earth. The end of the State is thus the virtue and happiness
(not pleasure) of the citizens. And since this is only possible {227}
through education, the State's primary function is educational.
Since the State is to be founded upon reason, its laws must be
rational, and rational laws can only be made by rational men,
philosophers. The rulers must be philosophers. And since the
philosophers are few, we must have an aristocracy, not of birth, or of
wealth, but of intellect. The first operative principle of the State
is reason, the second is force. For it is not to be expected that the
irrational masses will willingly submit to rational laws. They must be
compelled. And since the work of the world must go on, the third
operative principle will be labour. Plato believed in the principle of
division of labour. Only he can excel at any occupation whose life is
devoted to it. Hence to the three operative principles correspond
three classes, castes, or professions. Reason is embodied in the
philosopher-rulers, force in the warriors, labour in the masses. This
division of the functions of the State is based upon the threefold
division of the soul. To the rational soul correspond the
philosopher-rulers, to the nobler half of the mortal soul the
warriors, to the appetitive soul the masses. Consequently the four
cardinal virtues belong to the State through the functioning of the
three classes. The virtue of the philosopher-rulers is wisdom, of the
warriors courage, of the masses, temperance. The harmonious
co-operation of all three produces justice.
The rulers must not cease to be philosophers. Most of their time must
be spent in the study of the Ideas, philosophy, and only a portion in
the affairs of government. This is rendered possible by the system of
taking turns. Those who are not at any particular time {228} engaged
upon government retire into thought. The duty of the warriors is the
protection of the State, both against its external enemies, and
against the irrational impulses of the masses of its own citizens.
Normally, the latter will be their chief duty, the enforcement of the
decrees of the philosopher-rulers upon the masses. The masses will
engage themselves in trade, commerce, and agriculture. Both the other
ranks are prohibited from soiling their fingers with trade or
agriculture, upon which Plato, as a Greek aristocrat, looked down with
unbounded contempt. To what rank a citizen belongs is not determined
by birth, nor by individual choice. No individual can choose his own
profession. This will be determined by the officers of the State, who
will base their decision, however, upon the disposition and
capabilities of the individual. As they have also to decide the
numbers required for each rank, the magistrates also control the birth
of children. Parents cannot have children when they wish. The sanction
of the State is required.
Since the end of the State is the virtue of the citizens, this
involves the destruction of whatever is evil and the encouragement of
whatever is good. To compass the destruction of evil, the children of
bad parents, or offspring not sanctioned by the State, will be
destroyed. Weak and sickly children will also not be allowed to live.
The positive encouragement of good involves the education of the
citizens by the State. Children from their earliest years do not
belong to their parents, but to the State. They are, therefore, at
once removed from the custody of their parents, and transferred to
State nurseries. Since the parents are to have no {229} property nor
interest in them, stringent means are adopted to see that, after
removal to the public nurseries, parents shall never again be able to
recognize their own children. All the details of the educational
curriculum are decreed by the State. Poetry, for example, is only
allowed in an emasculated form. Of the three kinds, epic, dramatic,
and lyric, the two former are banished from the State altogether,
because, in the base example of the immorality of the gods, which they
depict, they are powerful instruments in the propagation of evil. Only
lyric poetry is allowed, and that under strict supervision. The
subject, the form, even the metre, will be prescribed by the proper
authorities. Poetry is not recognized as valuable in itself, but only
as an educative moral influence. All poems, therefore, must strictly
inculcate virtue.
It is, in Plato's opinion, intolerable that the individual should have
any interest apart from the interests of the State. Private interests
clash with those of the community, and must therefore be abolished.
The individual can possess no property either in material things, or
in the members of his family. This involves the community of goods,
community of wives, and the State ownership of children from their
birth.
6. Views upon Art.
In modern times aesthetics is recognized as a separate division of
philosophy. This was not the case in Plato's time, and yet his
opinions upon art cannot be fitted into either dialectic, physics, or
ethics. On the other hand, they cannot be ignored, and there is
nothing for it, therefore, but to treat them as a sort of appendix
{230} to his philosophy. Plato has no systematic theory of art, but
only scattered opinions, the most important of which will now be
mentioned.
Most modern theories of art are based upon the view that art is an end
in itself, that the beautiful has, as such, absolute value, and not
value merely as a means to some further end. Upon such a view, art is
recognized as autonomous within its own sphere, governed only by its
own laws, judged only by its own standards. It cannot be judged, as
Tolstoi would have us believe, by the standard of morals. The
beautiful is not a means to the good. They may be indeed, ultimately
identical, but their identity cannot be recognized till their
difference has been admitted. Nor can one be subordinated to the
other.
Now this view of art finds no place at all in Plato's thought. Art is,
for him, absolutely subservient both to morals and to philosophy. That
it subserves morality we see from the "Republic," where only that
poetry is allowed which inculcates virtue, and only because it
inculcates virtue. It is no sufficient justification of a poem to
plead that it is beautiful. Beautiful or not, if it does not subserve
the ends of morality, it is forbidden. Hence too the preposterous
notion that its exercise is to be controlled, even in details, by the
State. That this would mean the utter destruction of art either did
not occur to Plato, or if it did, did not deter him. If poetry cannot
exist under the yoke of morality, it must not be allowed to exist at
all. That art is merely a means to philosophy is even more evident.
The end of all education is the knowledge of the Ideas, and every
other subject, science, mathematics, art, is introduced into the {231}
educational curriculum solely as a preparation for that end. They have
no value in themselves. This is obvious from the teaching of the
"Republic," and it is even more evident in the "Symposium," where the
love of beautiful objects is made to end, not in itself, but in
philosophy.
Plato's low estimate of art appears also in his theory of art as
imitation, and his contemptuous references to the nature of artistic
genius. As to the first, art is, to him, only imitation. It is the
copy of an object of the senses, and this again is only a copy of an
Idea. Hence a work of art is only a copy of a copy. Plato did not
recognise the creativeness of art. This view is certainly false. If
the aims of art were merely to imitate, a photograph would be the best
picture, since it is the most accurate copy of its object. What Plato
failed to see was that the artist does not copy his object, but
idealizes it. And this means that he does not see the object simply as
an object, but as the revelation of an Idea. He does not see the
phenomenon with the eyes of other men, but penetrates the sensuous
envelope and exhibits the Idea shining through the veils of sense.
The second point is Plato's estimate of artistic genius. The artist
does not work by reason, but by inspiration. He does not, or he should
not, create the beautiful by means of rules, or by the application of
principles. It is only after the work of art is created that the
critic discovers rules in it. This does not mean that the discovery of
rules is false, but that the artist follows them unconsciously and
instinctively. If, for example, we believe Aristotle's dictum that the
object of tragedy {232} is to purge the heart by terror and pity, we
do not mean that the tragedian deliberately sets out to accomplish
that end. He does so without knowing or intending it. And this kind of
instinctive impulse we call the inspiration of the artist. Now Plato
fully recognizes these facts. But far from considering inspiration
something exalted, he thinks it, on the contrary, comparatively low
and contemptible, just because it is not rational. He calls it "divine
madness," divine indeed, because the artist produces beautiful things,
but madness because he himself does not know how or why he has done
it. The poet says very wise and beautiful things, but he does not know
why they are wise and beautiful. He merely feels, and does not
understand anything. His inspiration, therefore, is not on the level
of knowledge, but only of right opinion, which knows what is true, but
does not know why.
Plato's views of art are thus not satisfactory. He is doubtless right
in placing inspiration below reason, and art below philosophy. They do
stand to each other in the relation of higher and lower. Not that such
a question can be decided by mere personal preferences. The usual
discussions whether art or philosophy is better, whether emotion or
reason is higher, are pointless and insipid, because the disputants
merely exalt their personal peculiarities. The man of artistic
temperament naturally prefers art, and says it is the highest. The
philosopher exalts philosophy above art, merely because it is his pet
hobby. This kind of discussion is futile. The matter must be decided
upon some principle. And the principle is quite clear. Both art and
philosophy have the same object, the {233} apprehension of the
Absolute, or the Idea. Philosophy apprehends it as it is in itself,
that is to say, as thought. Art apprehends it in a merely sensuous
form. Philosophy apprehends it in its truth, art in a comparatively
untrue way. Philosophy, therefore, is the higher. But while any true
philosophy of art must recognize this, it must not interpret it to
mean that art is to be made merely a means towards philosophy. It must
somehow find room for the recognition of the truth that art is an end
in itself, and it is in this that Plato fails.
Aristotle, who had no spark of artistic capacity in his composition,
whose own writings are the severest of scientific treatises, did far
greater justice to art than Plato, and propounded a far more
satisfactory theory. Plato, himself a great artist, is utterly unjust
to art. Paradoxical as it may appear, the very reason why Aristotle
could be just to art was that he was no artist. Being solely a
philosopher, his own writings are scientific and inartistic. This
enables him to recognize art as a separate sphere, and therefore as
having its own rights. Plato could not keep the two separate. His
dialogues are both works of art and of philosophy. We have seen
already that this fact exercised an evil influence on his philosophy,
since it made him substitute poetic myths for scientific explanation.
Now we see that it exercised an equally evil influence on his views of
art. As a philosopher-artist his own practice is to use literary art
solely as a means towards the expression of philosophical ideas. And
this colours his whole view of art. It is, to him, nothing but a means
towards philosophy. And this is the tap-root of his entire view of the
subject.
{234}
7. Critical Estimate of Plato's Philosophy,
If we are to form a just estimate of the value of Plato's philosophy,
we must not fritter away our criticism on the minor points, the
external details, the mere outworks of the system. We must get at the
heart and governing centre of it all. Amid the mass of thought which
Plato has developed, in all departments of speculation, that which
stands out as the central thesis of the whole system is the theory of
Ideas. All else is but deduction from this. His physics, his ethics,
his politics, his views upon art, all flow from this one governing
theory. It is here then that we must look, alike for the merits and
the defects of Plato's system.
The theory of Ideas is not a something sprung suddenly upon the world
out of Plato's brain. It has its roots in the past. It is, as
Aristotle showed, the outcome of Eleatic, Heracleitean, and Socratic
determinations. Fundamentally, however, it grows out of the
distinction between sense and reason, which had been the common
property of Greek thinkers since the time of Parmenides. Parmenides
was the first to emphasize this distinction, and to teach that the
truth is to be found by reason, the world of sense being illusory.
Heracleitus, and even Democritus, were pronounced adherents of reason,
as against sense. The crisis came with the Sophists, who attempted to
obliterate the distinction altogether, and to find all knowledge in
sensation, thus calling forth the opposition of Socrates and Plato. As
against them Socrates pointed out that all knowledge is through
concepts, reason: and Plato added to this that the concept is not a
mere rule of thought but a metaphysical reality. This was the
substance of the theory of Ideas. {235} Every philosophy which makes a
systematic attempt to solve the riddle of the universe necessarily
begins with a theory of the nature of that absolute and ultimate
reality from which the universe is derived. This absolute reality we
will call simply the Absolute. Plato's theory is that the Absolute
consists of concepts. To say that the Absolute is reason, is thought,
is concepts, is the universal--these are merely four different
expressions of the same theory. Now this proposition, that the
Absolute is reason, is the fundamental thesis of all idealism. Since
Plato's time there have been several great idealistic systems of
philosophy. That the Absolute is reason is the central teaching of
them all. Plato, therefore, is the founder and initiator of all
idealism. It is this that gives him his great place in the history of
philosophy. That the Absolute is universal thought, this is what Plato
has contributed to the philosophical speculation of the world. This is
his crowning merit.
But we must go somewhat more into details. We must see how far he
applied this principle successfully to the unravelment of the great
problems of philosophy. In lecturing upon the Eleatics, I said that
any successful philosophy must satisfy at least two conditions. It
must give such an account of the Absolute, that the Absolute is shown
as capable of explaining the world. It must be possible to deduce the
actual world of facts from the first principle. Secondly, not only
must this first principle explain the world; it must also explain
itself. It must be really ultimate, that is, we must not, in order to
understand it, have to refer to anything beyond and outside it. If we
have to do so then our ultimate is not an ultimate at all; our first
principle {236} is not first. That thing by means of which we explain
it must itself be the ultimate reality. And besides being ultimate,
our principle must be wholly intelligible. It must not be a mere
ultimate mystery; for to reduce the whole world to an ultimate mystery
is clearly not to explain it. Our first principle must, in a word, be
self-explanatory. Let us apply this two-fold test to Plato's system.
Let us see, firstly, whether the principle of Ideas explains the
world, and secondly, whether it explains itself.
Does it explain the world? Is the actual existence of things, horses,
trees, stars, men, explained by it? What, in the first place, is the
relation between things and the Ideas? Things, says Plato, are
"copies," or "imitations" of the Ideas. They "participate" in the
Ideas. The Ideas are "archetypal" of things. Now all these phrases are
mere poetic metaphors. They do not really tell us how things are
related to Ideas. But suppose we ignore this, and assume, for the sake
of argument, that we understand what is meant by "participation" and
that things are, in the literal sense, "copies" of Ideas. The question
still remains, why do such copies exist, how do they arise? Now, if
this problem is to be solved, it is not enough to show, merely as a
fact, that, by some mysterious act, copies of Ideas come into
existence. There must be a reason for it, and this reason it is the
business of philosophy to explain. This reason, too, must exist in the
nature of the Ideas themselves, and not outside them. There must be,
in the very nature of the Ideas, some inner necessity which forces
them to reproduce themselves in things. This is what we {237} mean by
saying that the Ideas are a sufficient explanation of the existence of
things. But there is in Plato's Ideas no such necessity. The Ideas are
defined as being the sole reality. They have already all reality in
themselves. They are self-sufficient. They lack nothing. It is not
necessary for them further to realize their being in the concrete
manifestation of things, because they, as wholly real, need no
realization. Why, then, should they not remain for ever simply as they
are? Why should they go out of themselves into things? Why should they
not remain in themselves and by themselves? Why should they need to
reproduce themselves in objects? There are, we know, white objects in
the universe. Their existence, we are told, is explained by the Idea
of whiteness? But why should the Idea of whiteness produce white
things? It is itself the perfect whiteness. Why should it stir itself?
Why should it not remain by itself, apart, sterile, in the world of
Ideas, for all eternity? We cannot see. There is in the Ideas no
necessity urging them towards reproduction of themselves, and this
means that they possess no principle for the explanation of things.
Nevertheless Plato has to make some attempt to meet the difficulty.
And as the Ideas are themselves impotent to produce things, Plato,
unable to solve the problem by reason, attempts to solve it by
violence. He drags in the notion of God from nowhere in particular,
and uses him as a _deus ex machina_. God fashions matter into the
images of Ideas. The very fact that Plato is forced to introduce a
creator shows that, in the Ideas themselves, there is no ground of
explanation. Things ought to be explained by the Ideas themselves,
{238} but as they are incapable of explaining anything, God is called
upon to do their work for them. Thus Plato, faced with the problem of
existence, practically deserts his theory of Ideas, and falls back
upon a crude theism. Or if we say that the term God is not to be taken
literally, and that Plato uses it merely as a figurative term for the
Idea of Good, then this saves Plato from the charge of introducing a
theism altogether inconsistent with his philosophy, but it brings us
back to the old difficulty. For in this case, the existence of things
must be explained by means of the Idea of the Good. But this Idea is
just as impotent as the other Ideas.
In this connection, too, the dualism of Plato's system becomes
evident. If everything is grounded in the one ultimate reality, the
Ideas, then the entire universe must be clasped together in a system,
all parts of which flow out of the Ideas. If there exists in the
universe anything which stands aloof from this system, remains
isolated, and cannot be reduced to a manifestation of the Ideas, then
the philosophy has failed to explain the world, and we have before us
a confessed dualism. Now not only has Plato to drag in God for the
explanation of things, he has also to drag in matter. God takes matter
and forms it into copies of the Ideas. But what is this matter, and
where does it spring from? Clearly, if the sole reality is the Ideas,
matter, like all else, must be grounded in the Ideas. But this is not
the case in Plato's system. Matter appears as a principle quite
independent of the Ideas. As its being is self-derived and original,
it must be itself a substance. But this is just what Plato denies,
calling it absolute {239} not-being. Yet since it has not its source
in the Ideas or in anything outside itself, we must say that though
Plato calls it absolute not-being, it is in fact an absolute being.
The Ideas and matter stand face to face in Plato's system neither
derived from the other, equally ultimate co-ordinate, absolute
realities. This is sheer dualism.
The source of this dualism is to be found in the absolute separation
which Plato makes between sense and reason. He places the world of
sense on one side, the world of reason on the other, as things
radically different and opposed. Hence it is impossible for him ever
to bridge the gulf that he has himself created between them. We may
expect the dualism of a philosophy which builds upon such premises to
break out at numerous points in the system. And so indeed it does. It
exhibits itself as the dualism of Ideas and matter, of the sense-world
and the thought-world, of body and soul. Not, of course, that it is
not quite right to recognize the distinction between sense and reason.
Any genuine philosophy must recognize that. And no doubt too it is
right to place truth and reality on the side of reason rather than
sense. But although sense and reason are distinct, they must also be
identical. They must be divergent streams flowing from one source. And
this means that a philosophy which considers the absolute reality to
be reason must exhibit sense as a lower form of reason. Because Plato
fails to see the identity of sense and reason, as well as their
difference, his philosophy becomes a continual fruitless effort to
overreach the dualism thus generated.
Thus the answer to our first question, whether the theory of Ideas
explains the world of things, must be {240} answered in the negative.
Let us pass on to the second test. Is the principle of Ideas a
self-explanatory principle? Such a principle must be understood purely
out of itself. It must not be a principle, like that of the
materialist, which merely reduces the whole universe to an ultimate
mysterious fact. For even if it be shown that the reason of everything
is matter, it is still open to us to ask what the reason of matter is.
We cannot see any reason why matter should exist. It is a mere fact,
which dogmatically forces itself upon our consciousness without giving
any reason for itself. Our principle must be such that we cannot ask a
further reason of it. It must be its own reason, and so in itself
satisfy the demand for a final explanation. Now there is only one such
principle in the world, namely, reason itself. You can ask the reason
of everything else in the world. You can ask the reason of the sun,
the moon, stars, the soul, God, or the devil. But you cannot ask the
reason of reason, because reason is its own reason. Let us put the
same thought in another way. When we demand the explanation of
anything, what do we mean by explanation? What is it we want? Do we
not mean that the thing appears to us irrational, and we want it shown
that it is rational? When this is done, we say it is explained. Think,
for example, of what is called the problem of evil. People often talk
of it as the problem of the "origin of evil," as if what we want to
know is, how evil began. But even if we knew this, it would not
explain anything. Suppose that evil began because someone ate an
apple. Does this make the matter any clearer? Do we feel that all our
difficulties about the existence of evil are solved? No. This is {241}
not what we want to know. The difficulty is that evil appears to us
something irrational. The problem can only be solved by showing us
that somehow, in spite of appearances, it is rational that evil should
exist. Show us this, and evil is explained. Explanation of a thing,
then, means showing that the thing is rational. Now we can ask that
everything else in the world should be shown to be rational. But we
cannot demand that the philosopher shall show that reason is rational.
This is absurd. Reason is what is already absolutely rational. It is
what explains itself. It is its own reason. It is a self-explanatory
principle. This, then, must be the principle of which we are in
search. The Absolute, we said, must be a self-explanatory principle,
and there is only one such, namely, reason. The Absolute, therefore,
is reason.
It was the greatness and glory of Plato to have seen this, and thereby
to have become the founder of all true philosophy. For to say that the
Absolute is concepts is the same as saying it is reason. It might
seem, then, that Plato has satisfied the second canon of criticism. He
takes as first principle a self-explanatory reality. But we cannot
quite so quickly jump to this conclusion. After all, the mere word
reason is not a key which will unlock to us the doors of the universe.
Something more is necessary than the mere word. We must, in fact, be
told what reason is. Now there are two senses in which we might ask
the question, what reason is, one of which is legitimate, the other
illegitimate. It is illegitimate to ask what reason is, in the sense
of asking that it shall be explained to us in terms of something else,
which is not reason. This would be {242} to give up our belief that
reason is its own reason. It would be to seek the reason of reason in
something which is not reason. It would be to admit that reason, in
itself, is not rational. And this is absurd. But it is legitimate to
ask, what reason is, meaning thereby, what is the _content_ of reason.
The content of reason, we have seen, is concepts. But what concepts?
How are we to know whether any particular concept is part of the
system of reason or not? Only, it is evident, by ascertaining whether
it is a rational concept. If a concept is wholly rational, then it is
a part of reason. If not, not. What we need, then, is a detailed
account of all the concepts which reason contains, and a proof that
each of these concepts is really rational. It is obvious that only in
this way can we make a satisfactory beginning in philosophy. Before we
can show that reason explains, that is, rationalizes the world, we
must surely first show that reason itself is rational, or rather, to
be more accurate, that _our conception_ of reason is rational. There
must not be any mere inexplicable facts, any mysteries, any dark
places, in our notion of reason. It must be penetrated through and
through by the light of reason. It must be absolutely transparent,
crystalline. How can we hope to explain the world, if our very first
principle itself contains irrationalities?
Each concept then must prove itself rational. And this means that it
must be a necessary concept. A necessary proposition, we saw, is one,
such as that two and two equal four, the opposite of which is
unthinkable. So for Plato's Ideas to be really necessary it ought to
be logically impossible for us to deny their {243} reality. It ought
to be impossible to think the world at all without these concepts. To
attempt to deny them ought to be shown to be self-contradictory. They
ought to be so necessarily involved in reason that thought without
them becomes impossible. Clearly this is the same as saying that the
Ideas must not be mere ultimate inexplicable facts. Of such a fact we
assert merely that it is so, but we cannot see any reason for it. To
see a reason for it is the same as seeing its necessity, seeing not
merely that it is so, but that it must be so.
Now Plato's Ideas are not of this necessary kind. There is, we are
told, an Idea of whiteness. But why should there be such an Idea? It
is a mere fact. It is not a necessity. We can think the world quite
well without the Idea of whiteness. The world, so far as we can see,
could get on perfectly well without either white objects or the Idea
of whiteness. To deny its reality leads to no self-contradictions. Put
it in another way. There are certainly white objects in the world. We
demand that these, among other things, be explained. Plato tells us,
by way of explanation, that there are white objects because there is
an Idea of whiteness. But in that case why is there an Idea of
whiteness? We cannot see. There is no reason. There is no necessity in
this. The same thing applies to all the other Ideas. They are not
rational concepts. They are not a part of the system of reason.
But at this point, perhaps, a glimmer of hope dawns upon us. We ask
the reason for these Ideas. Has not Plato asserted that the ultimate
reason and ground of all the lower Ideas will be found in the supreme
Idea of {244} the Good? Now if this is so, it means that the lower
Ideas must find their necessity in the highest Idea. If we could see
that the Idea of the Good necessarily involves the other Ideas, then
these other Ideas would be really explained. In other words, we ought
to be able to deduce all the other Ideas from this one Idea. It ought
to be possible to show that, granted the Idea of the Good, all the
other Ideas necessarily follow, that to assume the Good and deny the
other Ideas would be self-contradictory and unthinkable. There are
examples in Plato of the kind of deduction we require. For example, in
the "Parmenides" he showed that the Idea of the one necessarily
involves the Idea of the many, and vice versa. You cannot think the
one without also thinking the many. This means that the many is
deduced from the one, and the one from the many. Just in the same way,
we ought to be able to deduce the Idea of whiteness from the Idea of
the Good. But this is clearly not possible. You may analyse the Good
as long as you like, you may turn it in every conceivable direction,
but you cannot get whiteness out of it. The two Ideas do not involve
each other. They are thinkable apart. It is quite possible to think
the Good without thinking whiteness. And it is the same with all the
other Ideas. None of them can be deduced from the Good.
And the reason of this is very obvious. Just as the lower Ideas
contain only what is common among the things of a class, and exclude
their differences, so the higher Ideas include what is common to the
Ideas that come under them, but exclude what is not common. For
example, the Idea of colour contains what white, blue, red, and green,
have in common. But all colours {245} have not whiteness in common.
Green, for example, is not white. Hence the Idea of colour excludes
the Idea of whiteness, and it likewise excludes all the Ideas of the
other particular colours. So too the highest Idea of all contains only
what all the Ideas agree in, but all the rest falls outside it. Thus
the Idea of whiteness is perfect in its kind. And as all Ideas are
likewise perfect, the highest Idea is that in which they all agree,
namely, perfection itself. But this means that the perfection of the
Idea of whiteness is contained in the supreme Idea, but its specific
character in which it differs from other Ideas is excluded. Its
specific character is just its whiteness. Thus the perfection of
whiteness is contained in the Good, but its whiteness is not.
Consequently it is impossible to deduce whiteness from the Good,
because the Good does not contain whiteness. You cannot get out of it
what is not in it. When Plato deduced the many from the one, he did so
only by showing that the One contains the many. He cannot deduce
whiteness from goodness, because goodness does not contain whiteness.
The lower Ideas thus have not the character of necessity. They are
mere facts. And the hope that we shall find their necessity in the
supreme Idea fails. But suppose we waive this. Suppose we grant that
there must be an Idea of whiteness, because there is an Idea of the
Good. Then why is there an Idea of the Good? What is the necessity of
that? We cannot see any necessity in it. What we said of the other
Ideas applies with equal force to the highest Idea. The Good may be a
necessary Idea, but Plato has not shown it.
Thus, though Plato named reason as the Absolute, {246} and though
reason is a self-explanatory principle, his account of the detailed
content of reason is so unsatisfactory that none of the concepts which
he includes in it are really shown to be rational. His philosophy
breaks down upon the second test as it did upon the first. He has
neither explained the world from the Ideas, nor has he made the Ideas
explain themselves.
There is one other defect in Plato's system which is of capital
importance. There runs throughout it a confusion between the notions
of reality and existence. To distinguish between existence and reality
is an essential feature of all idealism. Even if we go back to the dim
idealism of the Eleatics, we shall see this. Zeno, we saw, denied
motion, multiplicity, and the world of sense. But he did not deny the
existence of the world. That is an impossibility. Even if the world is
delusion, the delusion exists. What he denied was the reality of
existence. But if reality is not existence, what is it? It is Being,
replied the Eleatics. But Being does not exist. Whatever exists is
this or that particular sort of being. Being itself is not anywhere to
be found. Thus the Eleatics first denied that existence is reality,
and then that reality exists. They did not themselves draw this
conclusion, but it is involved in their whole position.
With a fully developed idealism, like Plato's, this ought to be still
clearer. And, in a sense, it is. The individual horse is not real. But
it certainly exists. The universal horse is real. But it does not
exist. But, upon this last point, Plato wavered and fell. He cannot
resist the temptation to think of the absolute reality as existing.
And consequently the Ideas are {247} not merely thought as the real
universal in the world, but as having a separate existence in a world
of their own. Plato must have realised what is, in truth, involved in
his whole position, that the absolute reality has no existence. For he
tells us that it is the universal, and not any particular individual
thing. But everything that exists is an individual thing. Again, he
tells us that the Idea is outside time. But whatever exists must exist
at some time. Here then this central idealistic thought seems well
fixed in Plato's mind. But when he goes on to speak of recollection
and reincarnation, when he tells us that the soul before birth dwelt
apart in the world of Ideas, to which after death it may hope to
return, it is clear that Plato has forgotten his own philosophy, that
he is now thinking of the Ideas as individual existences in a world of
their own. This is a world of Ideas having a separate existence and
place of its own. It is not this world. It is a world beyond. Thus the
Platonic philosophy which began on a high level of idealistic
thinking, proclaiming the sole reality of the universal, ends by
turning the universal itself into nothing but an existent particular.
It is the old old story of trying to form mental pictures of that
which no picture is adequate to comprehend. Since all pictures are
formed out of sensuous materials, and since we can form no picture of
anything that is not an individual thing, to form a picture of the
universal necessarily means thinking of it as just what it is not, an
individual. So Plato commits the greatest sin that can be ascribed to
a philosopher. He treats thought as a thing.
To sum up. Plato is the great founder of idealism, the initiator of
all subsequent truths in philosophy. {248} But, as always with
pioneers, his idealism is crude. It cannot explain the world; it
cannot explain itself. It cannot even keep true to its own principles,
because, having for the first time in history definitely enunciated
the truth that reality is the universal, it straightway forgets its
own creed and plunges back into a particularism which regards the
Ideas as existent individuals. It was these defects which Aristotle
set himself to rectify in a purer idealism, shorn of Plato's
impurities.
{249}
CHAPTER XIII
ARISTOTLE
1. Life, Writings, and general character of his Work.
Aristotle was born in 384 B.C. at Stagirus, a Grecian colony and
seaport on the coast of Thrace. His father Nichomachus was court
physician to King Amyntas of Macedonia, and from this began
Aristotle's long association with the Macedonian Court, which
considerably influenced his life and destinies. While he was still a
boy his father died, and he was sent by his guardian, Proxenus, to
Athens, the intellectual centre of the world, to complete his
education. He was then aged seventeen. He joined the Academy and
studied under Plato, attending the latter's lectures for a period of
twenty years. In subsequent times, Aristotle's detractors, anxious to
vilify his character, accused him of "ingratitude" to his master,
Plato. It was said that Plato's old age had been embittered by
dissensions in the school caused by the factious spirit of Aristotle.
That there is no ground for attaching any blame to Aristotle for the
troubles of Plato, which either did not exist or have been grossly
exaggerated, is evident both from the facts within our knowledge and
from the reference to Plato in Aristotle's works. It is not likely
that, had Aristotle rendered himself genuinely objectionable, he could
have remained for twenty years in {250} the Academy, and only left it
upon the death of Plato. Moreover, although Aristotle in his works
attacks the teaching of Plato with unsparing vigour, there is nowhere
to be found in these attacks any suggestion of acrimony or personal
rancour. On the contrary, he refers to himself as the friend of Plato,
but a greater friend of the truth. The fact, in all probability, is
that a man of such independent and original mind as Aristotle did not
accord to Plato the kind of blind adoration and hero-worship which he
may have received from the inferior intellects in the school. As is so
often the case with young men of marked ability, the brilliant student
may have suffered from the impatience and self-assertion of youth.
There was certainly nothing worse.
While at the Academy Aristotle exhibited an unflagging spirit and
unwearied zeal in the pursuit of knowledge in all its forms, a spirit
which gave rise to nick-names and anecdotes, which probably contained
as much truth, or as little, as most of the anecdotes which gather
round remarkable characters. One of these stories was that he used a
mechanical contrivance to wake him up whenever sleep threatened to put
an end to his hours of study.
In 347 B.C. Plato died, and his nephew Speusippus was chosen as head
of the Academy. Aristotle left Athens with his fellow-student
Xenocrates, and together they repaired to the court of Hermeias, King
of Atarneus, in Asia Minor. Hermeias, a man of low origin, but of high
instincts and advanced education, had himself attended the lectures of
Plato, and received the two young philosophers as welcome guests.
Aristotle stayed three years at Atarneus, and, while there, married
{251} Pythias, the niece of the King. In later life he was married a
second time to one Herpyllis, who bore him a son, Nichomachus. At the
end of three years Hermeias fell a victim to the treachery of the
Persians, and Aristotle went to Mytilene. Here he remained for several
years till he received an invitation from Philip of Macedonia to
become the tutor of the young Alexander, afterwards conqueror of the
world, then aged thirteen. Aristotle obeyed the summons, and for about
five years superintended the education of Alexander. Both Philip and
Alexander appear to have paid Aristotle high honour, and there were
stories that he was supplied by the Macedonian court, not only with
funds for the prosecution of learning, but even with thousands of
slaves for the collection of specimens. These stories are probably
false and certainly exaggerated. But there is no doubt that, in his
scientific and philosophical enquiries, he was backed by the influence
of the court, and could even perhaps have looked to that quarter for
supplies, had it ever been necessary.
Upon the death of Philip, Alexander succeeded to the kingship. The
period of his studies was now over, and he began to make preparations
for his subsequent conquests. Aristotle's work being finished, he
returned to Athens, which he had not visited since the death of Plato.
He found the Platonic school flourishing under Xenocrates, and
Platonism the dominant philosophy of Athens. He thereupon set up his
own school at a place called the Lyceum. It was in connection with
this that his followers became known, in after years, as the
"peripatetics," a name which arose from Aristotle's habit of walking
about as he discoursed. The period of {252} his residence in Athens
lasted thirteen years, during which time he was occupied in the
leadership of his school and in literary labours. This appears to have
been the most fruitful period of his life. There is no doubt that all
his most important writings were composed at this time. But at the end
of this period his fortunes changed.
In B.C. 323 Alexander the Great died suddenly at Babylon in the midst
of his triumphs. The Athenian Government was in the hands of a
pro-Macedonian party. Upon the death of Alexander this party was
overthrown, and a general reaction occurred against everything
Macedonian. Alexander had been regarded in Greece much as Napoleon was
regarded in Europe a century ago. He had insulted the free Greek
cities. He had even sacked the city of Thebes. The whole of Greece
lived in perpetual terror of invasion. Now that this fear was removed
by his death, there was a general outburst of feeling against
Macedonia. An anti-Macedonian party came into power. Now Aristotle had
always been regarded as a representative and protege of the Macedonian
court, although, as a matter of fact, he had recently fallen out of
favour with the autocratic Alexander. A charge of impiety was trumped
up against him. To escape prosecution he fled to Chalcis in Euboea, in
order that, as he said, "the Athenians might not have another
opportunity of sinning against philosophy as they had already done in
the person of Socrates." He perhaps intended to return to Athens as
soon as the storm had blown over. But in the first year of his
residence at Chalcis he was overtaken by a sudden illness, and died at
the age of sixty-three, in B.C. 322.
{253}
Aristotle is said to have composed some four hundred books. Our
astonishment at this productivity diminishes somewhat when we remember
that what is here called a "book" is much the same as what we should
call a chapter in a modern treatise. More than three-quarters of these
writings have been lost. But, by good fortune, what remains to us is
undoubtedly by far the most important part, and we have preserved in
it a fairly complete account of the whole Aristotelian system in all
its departments. Nearly all the writings, however, have come down to
us in a mutilated state. This is especially the case with the
"Metaphysics." This treatise is unfinished, and it was probably left
unfinished by its author at his death. But apart from this, several of
the books of the "Metaphysics" are undoubtedly spurious. Others
apparently come in the wrong order. We end one book in the middle of a
discussion, and when we begin the next we find ourselves in the middle
of an entirely different subject. There are frequent repetitions, and
parts of it read as if they were mere lecture notes. There are many
interpolations. The same characteristics are to be observed in
Aristotle's other writings, though in a less degree. It seems probable
that they were not intended, in their present state, for publication.
Final revision and finishing touches are lacking. In spite of these
defects, the writings are voluminous and clear enough to enable us to
trace out the whole of the main positions of Aristotle's thought.
We saw, in the case of Plato, that, as his literary activity lasted
over a period of half a century, during which his philosophy was in
constant development, it became important to trace this development in
the {254} order of his Dialogues. The same thing is not true in the
case of Aristotle. The whole of his writings, or rather those that
have come down to us, seem to have been written during his last
thirteen years, while he was at Athens, that is to say, after he had
passed his fiftieth year. His system was then complete, mature, and
fully developed. The question of the order in which they were written
has no great importance. The result of critical investigations,
however, is to show that he probably began with the various works upon
logic, composed next the treatises upon physical science, next the
ethical and political books, and lastly the "Metaphysics," which he
left unfinished.
It must not be forgotten that Aristotle was not only a philosopher in
the modern restricted sense of that term. He was a man of universal
learning. There is no branch of knowledge which did not receive his
attention, and upon which he was not the greatest expert of his time,
except perhaps mathematics. So far was he from being only an abstract
philosopher, that his natural tastes seem to have lain rather in the
field of physical science than of abstract thought. But his design
seems to have been to work over the entire field of knowledge,
thoroughly to overhaul the sciences already in existence, rejecting
what seemed false in the work of his predecessors, and invariably
adding to the residue valuable developments and suggestions of his
own. Where there was no science already in existence, his plan
involved the foundation of new sciences wherever necessary, and he
thus became the founder of at least two sciences, Logic and Zoology.
He thus attained to a pre-eminence in all branches {255} of knowledge
which would be impossible for a single man in modern times. His works
include treatises upon Logic and Metaphysics, upon Ethics, Politics,
and Art. He wrote a treatise upon the principles of Rhetoric, another
upon Astronomy, under the title "On the Heavens," another upon
Meteorology. Several of his treatises deal with the biology of animal
life, in which he was intensely interested. They include books
entitled "On the Parts of Animals," "On the Movements of Animals," "On
the Origin of Animals," as well as his great treatise, "Researches on
Animals," which contains an enormous mass of facts collected from
every possible source. It is true that a large proportion of these
facts have turned out to be fictions, but this was inevitable in the
infancy of science. It has been calculated that Aristotle shows
himself acquainted with about five hundred different species of living
beings, though they are not, of course, classified by him in the
modern way. With these books upon animals he founded the science of
Zoology, for no one before his day had made any special study of the
subject.
It has been said that everyone has either an Aristotelian or a
Platonic type of mind. As this implies that Aristotle and Plato are
opposites, it is considerably less than a half truth. No genuine
understanding of Aristotle can endorse the opinion that his
philosophical system was the opposite of Plato's. It would be truer to
say that Aristotle was the greatest of all Platonists, since his
system is still founded upon the Idea, and is an attempt to found an
idealism free from the defects of Plato's system. It is in fact a
development of Platonism. What is the cause then of the popular notion
that {256} Aristotle was the opposite of Plato? Now the fact is that
they _were_ opposites in many important respects. But there was a
fundamental agreement between them which lies deeper than the
differences. The differences are largely superficial, the agreement is
deep-seated. Hence it is the differences that are most obvious, and it
was the differences, too, which were most obvious to Aristotle
himself. The popular opinion arises largely from the fact that
Aristotle never loses an opportunity of attacking the Platonic theory
of Ideas. He is continually at pains to emphasize the difference
between himself and Plato, but says nothing of the agreement. But no
man is a judge of his own deeper relations to his predecessors and
contemporaries. It is only in after years, when the hubbub of
controversy has settled down into the silence of the past, that the
historian can see the true perspective, and can penetrate the
relations of each great man to the time in which he lived. Plato was
the founder of idealism, and his idealism was in many respects crude
and untenable. It was the special mission of Aristotle to clear away
these crudities, and so develop Platonism into a tenable philosophy.
And it was natural that he should emphasize the crudities, which he
had to fight so hard to overcome, rather than that substratum of truth
which Plato had already developed, and which therefore required no
special treatment at his hands. It was the differences between himself
and his predecessor which were most obvious to him, and it was
inevitable that he should adopt a thoroughly polemical attitude
towards his master.
But if the agreement was more deep-seated than the differences, and
lay in the recognition of the Idea as the {257} absolute foundation of
the world, the differences were none the less very striking. In the
first place, Aristotle loved facts. What he wanted was always definite
scientific knowledge. Plato, on the other hand, had no love of facts
and no gift for physical enquiries. And what disgusted Aristotle about
the system of Plato was the contempt which it poured upon the world of
sense. To depreciate objects of sense, and to proclaim the knowledge
of them valueless, was a fundamental characteristic of all Plato's
thinking. But the world of sense is the world of facts, and Aristotle
was deeply interested in facts. No matter in what branch of knowledge,
any fact was received by Aristotle with enthusiasm. To Plato it
appeared of no interest what the habits of some obscure animal might
be. That alone which should be pursued is the knowledge of the Idea.
And he went so far as to deny that knowledge of the sense-world could
properly be described as knowledge at all. But the habits of animals
appeared to Aristotle a matter worthy of investigation for its own
sake. Francis Bacon in his "Novum Organum" has many contemptuous
references to Aristotle. And the gist of them all is that Aristotle
had no regard for facts, but theorized a priori out of his head, and
that instead of patiently investigating the facts of nature, he
decided, upon so-called "rational" grounds, what nature ought to do,
and squared the facts with his theories.
It was natural for Bacon to be unjust to him. He, with the other
thinkers of his time, was engaged upon an uphill fight against
scholasticism, then dominant, which claimed to represent the true
teaching of Aristotle. And it was true that the schoolmen theorized a
priori, {258} and ignored facts, or, what was worse, appealed to the
writings of Aristotle to decide questions of fact which should have
been decided by an appeal to nature. And Bacon not unnaturally
confounded Aristotle with these modern Aristotelians, and attributed
to him the faults that were really theirs. But no man was ever keener
on facts than Aristotle as is proved by his treatises upon animals,
which contain evidences of astonishing patience and laborious work in
the collection of facts. It is true, however, that even in the domain
of facts, Aristotle, like all the ancients, was guilty of introducing
_a priori_ reasonings when they were quite out of place. Thus he does
not scruple to argue that the stars must move in circles because the
circle is the perfect figure. And numerous similar instances could be
quoted. But it was inevitable that, with science in its swaddling
clothes, without the aid of any instruments, or of any body of
previously ascertained truths, Aristotle should fall into these
snares. He well understood the fundamental necessity of all natural
sciences for a laborious investigation of facts, but, when this was
impossible, he used the only means in his power, his reason.
Secondly, in spite of Plato's rationalism, he had allowed to myths and
poetry a large share in the development of his thoughts, and had even
exhibited a distinct tendency towards mysticism. Here again what
Aristotle wanted was definite knowledge. It pained him to see poetic
metaphors substituted for rational explanation. And this accounts for
the third main difference between Plato and Aristotle, the marked
contrast in their prose styles. Plato was a master-artist in words.
Aristotle cared nothing for the ornaments and beauties of style. {259}
He harshly excludes them from his work. What alone he is intent upon
is the meaning, the truth that the words express. He is too much in
earnest with philosophy to lose himself in a haze of beautiful words,
or to be put off with metaphors instead of reasons. His style is even
harsh, abrupt, and ugly. But what it loses in beauty it gains in
clearness of conception. For every thought or shade of thought which
it is desired to express there is an accurate term. If no term in
common use will express the thought, Aristotle coins one. Hence he is
one of the greatest terminologists that ever lived. He adapted or
invented an enormous number of terms. He may be not unjustly regarded
as the founder of philosophical language, as the inventor of a
vocabulary of technical terms. Many of the terms used to this day to
express man's most abstract thoughts, were invented or introduced by
Aristotle. It must not be supposed that Aristotle wrote in a rigidly
scientific style because he had no aesthetic sense. The very contrary
is the case. His treatise on art shows him by far the best critic of
the ancient world, and in his appreciation and estimation of the
beautiful he far excels Plato. But he saw that art and science have
each their own sphere, and that it is fatal to confuse the two.
Nothing is so damaging to art as to be made the mere vehicle of
reasoning. Nothing is so damaging to philosophy as to allow itself to
be governed by poetry. If we want beauty, we must follow the path of
art. But if we desire truth, we must stick close to reason.
Aristotle's system falls most easily into the fivefold division of
logic, metaphysics, physics, ethics, and aesthetics.
{260}
2. Logic.
Not much need be said under this head, because whoever knows the
common logic of the text-books knows the logic of Aristotle. Of the
two branches of reasoning, deductive and inductive, Aristotle clearly
recognizes the latter. And many of his observations upon induction are
acute and penetrating. But he has not reduced induction to a science.
He has not laid bare the fundamental canons of inductive thought. This
was a work not performed until comparatively modern times. His name
therefore is more especially associated with deductive logic, of which
he was the founder. He not only founded the science, but practically
completed it. What we now know as "formal logic," what is to this day
contained in all text-books, taught in all schools and universities,
is, in all its essentials, nothing more than the logic of Aristotle.
His writings upon the subject include the treatment of the well-known
laws of thought, the doctrine of the ten categories, the five
predicables, the doctrines of terms, of propositions, of syllogisms,
and of the reduction of the other figures to the first figure of the
syllogism. And these heads might well form the list of contents of a
modern work on formal logic. In only two respects has any advance been
made upon Aristotle by subsequent logicians. The fourth figure of the
syllogism is not recognized by Aristotle; and he dealt only with
categorical syllogisms, and does not treat conditional syllogisms. But
whether or not the fourth figure of the syllogism has any value is
still a matter open to dispute. And though the doctrine of conditional
syllogisms is important, it is not essential, because all conditional
syllogisms can be reduced to categorical {261} syllogisms. The
categorical syllogism is the fundamental type of reasoning, to which
every other form of deduction can be reduced. As for the rest of the
huge treatises on formal logic which some moderns have produced, the
supposed additions are nothing but wearisome, endless, useless,
nauseating, academic distinctions and refinements, which are much
better forgotten than remembered. Aristotle's logic contains therefore
all that is essential to the subject. The only ground on which it can
be attacked is its wholly empirical procedure. But that is another
story. As a collection, arrangement, and analysis of the facts of
reason, it is to all intents and purposes finality achieved at one
stroke.
3. Metaphysics.
The treatise now known as the "Metaphysics" of Aristotle did not
originally bear that name. Aristotle's name for this subject is "first
philosophy," by which he means the knowledge of the first, highest, or
most general principles of the universe. All other branches of
knowledge are subordinate to this science, not because they are
inferior in value, but because they are lower in logical sequence as
dealing with principles less universal in their scope. Thus all the
special sciences deal with one or another particular sphere of being,
but the "first philosophy" has for its subject being as such, "being
so far forth as it is being." It studies, not the characteristics of
this or that kind of being, but the principles which are equally true
of all being. The laws of Zoology apply only to animals, but the
principles of the "first philosophy" apply to everything. The name
"metaphysics" came into use only half a century B.C., when {262}
Andronicus published a complete edition of Aristotle's known works. In
this edition the treatise on "first philosophy" was placed after the
"physics," and "metaphysics" signifies simply "after physics." The
derivation of the word thus appears to be merely accidental and
adventitious. Whether it was also in any way intended to signify that
the subject is "beyond physics," that is, deals with what transcends
physical existence, seems doubtful.
Aristotle's metaphysical theory grows naturally out of his polemic
against Plato's theory of Ideas, because his own system was in effect
simply an attempt to overcome the defects which he found in Plato. The
main heads of this polemic are the following:--
(1) Plato's Ideas do not explain the existence of things. To explain
why the world is here is after all the main problem of philosophy, and
Plato's theory fails to do this. Even admitting that, say, the Idea of
whiteness exists, we cannot see how it produces white objects.
(2) Plato has not explained the relation of Ideas to things. Things,
we are told, are "copies" of Ideas, and "participate" in them. But how
are we to understand this "participation"? In using such phrases, says
Aristotle, Plato is giving no real account of the relationship, but is
merely "uttering poetic metaphors."
(3) Even if the existence of things is explained by the Ideas, their
motion is not. Suppose that the Idea of whiteness produces white
things, the Idea of beauty beautiful things, and so on, yet, since the
Ideas themselves are immutable and motionless, so will be the world
which is their copy. Thus the universe would be {263} absolutely
static, like Coleridge's "painted ship upon a painted ocean." But the
world, on the contrary, is a world of change, motion, life, becoming.
Plato makes no attempt to explain the unceasing becoming of things.
Even if the Idea of whiteness explains white objects, yet why do these
objects arise, develop, decay, and cease to exist? To explain this
there must be some principle of motion in the Ideas themselves. But
there is not. They are immovable and lifeless.
(4) The world consists of a multitude of things, and it is the
business of philosophy to explain why they exist. By way of
explanation Plato merely assumes the existence of another multitude of
things, the Ideas. But the only effect of this is to double the number
of things to be explained. How does it help thus to duplicate
everything? And Aristotle likens Plato to a man who, being unable to
count with a small number, fancies that, if he doubles the number, he
will find it easier to count.
(5) The Ideas are supposed to be non-sensuous, but they are, in fact,
sensuous. Plato thought that a non-sensuous principle must be sought
in order to explain the world of sense. But not being able to find any
such principle, he merely took the objects of sense over again and
called them non-sensuous. But there is, in fact, no difference between
the horse and the Idea of the horse, between the man and the Idea of
the man, except a useless and meaningless "in-itself" or "in-general"
attached to each object of sense to make it appear something
different. The Ideas are nothing but hypostatized things of sense, and
Aristotle likens them to the anthropomorphic gods of the popular
religion. "As {264} these," he says, "are nothing but deified men, so
the Ideas are nothing but eternalized things of nature." Things are
said to be copies of Ideas, but in fact the Ideas are only copies of
things.
(6) Next comes the argument of the "third man," so called by Aristotle
from the illustration by which he explained it. Ideas are assumed in
order to explain what is common to many objects. Wherever there is a
common element there must be an Idea. Thus there is a common element
in all men, and therefore there is an Idea of man. But there is also
an element common to the individual man and to the Idea of man. There
must, therefore, be a further Idea, the "third man," to explain this.
And between this further Idea and the individual man there must be yet
another Idea to explain what they have in common, and so on _ad
infinitum_.
(7) But by far the most important of all Aristotle's objections to the
ideal theory, and that which, to all intents and purposes, sums up all
the others, is that it assumes that Ideas are the essences of things,
and yet places those essences outside the things themselves. The
essence of a thing must be in it, and not outside it. But Plato
separated Ideas from things, and placed the Ideas away somewhere in a
mysterious world of their own. The Idea, as the universal, can only
exist in the particular. Possibly the reality in all horses is the
universal horse, but the universal horse is not something that exists
by itself and independently of individual horses. Hence Plato was led
into the absurdity of talking as if, besides the individual horses we
know, there is somewhere another individual called the
horse-in-general, or as if besides white objects there is a thing
called {265} whiteness. And this is in fact the supreme
self-contradiction of the theory of Ideas, that it begins by saying
that the universal is real, and the particular unreal, but ends by
degrading the universal again into a particular. This is the same
thing as saying that Plato's mistake lay in first (rightly) seeing
that existence is not reality, but then (wrongly) going on to imagine
that the reality is an existence.
Out of this last objection grows Aristotle's own philosophy, the
fundamental principle of which is that the universal is indeed the
absolute reality, but that it is a universal which exists only in the
particular. What is reality? What is substance? This is the first
question for the metaphysician. Now substance is what has an
independent existence of its own; it is that whose being does not flow
into it from any source outside itself. Consequently, substance is
what is never a predicate; it is that to which all predicates are
applied. Thus in the proposition, "Gold is heavy," gold is the
subject, or substance, and "heavy" is its predicate. The heaviness is
dependent for its existence on the gold, and it is therefore the
latter, and not the former, that is the substance.
Now, keeping this in mind, are universals, as Plato asserts,
substances? No; because the universal is merely a common predicate
which attaches to many objects of a class. Thus the concept of man is
merely what is common to all men. It is the same thing as the
predicate "humanness." But humanness cannot exist apart from human
beings, any more than heaviness apart from the heavy object.
Universals, then, are not substances. But neither are particulars
substances. For there is no such thing as that which is absolutely
{266} particular and isolated. If humanness does not exist apart from
men, neither do men exist apart from humanness. Take away from a man
what he has in common with other men, and what he has in common with
other objects, and you will find that, having stripped him of all his
qualities, there is absolutely nothing left. We say gold is heavy,
yellow, malleable, etc. Now the heaviness, the yellowness, and the
other qualities, cannot exist apart from the gold. But it is equally
true that the gold cannot exist apart from its qualities. Strip off
all its qualities in thought, and then ask yourself what the gold
itself is apart from its qualities. You will find that your mind is a
total blank. In taking away the qualities you have taken away the gold
itself. The gold can only be thought through its qualities. It only
exists through its qualities. The gold, therefore, just as much
depends on the qualities for its existence as the qualities depend
upon the gold. Hence neither of them, considered apart from the other,
is substance. But the qualities are the universal element in the gold,
the gold without the qualities is the absolutely particular and
isolated. For, first, the yellowness is a quality which this gold has
in common with that gold, and is therefore a universal, and so with
all the qualities. Even if a particular piece of gold has a quality
possessed by no other gold, it is yet possessed by some other object
in the universe, or it would be unknowable. Every quality is
consequently a universal. Secondly, the gold without its qualities is
the absolutely particular. For, being stripped of all qualities, it is
stripped of whatever it has in common with other things; it is
stripped of whatever universality it has, and it remains an absolute
particular. Hence the {267} universal is not substance, nor is the
particular. For neither of them can exist without the other. Substance
must be a compound of the two; it must be the universal in the
particular. And this means that that alone which is substance is the
individual object, for example, the gold with all its qualities
attached to it.
It is usually believed that Aristotle contradicted himself in as much
as he first states, as above, that the individual object, the compound
of universal and particular, is substance, but later on allows a
superior reality to the universal, or "form" as he calls it, and in
effect teaches, like Plato, that the universal is what alone is
absolutely real, that is, that the universal is substance. I do not
agree that there is any real inconsistency in Aristotle. Or rather,
the inconsistency is one of words and not of thought. It must be
remembered that, whenever Aristotle says that the individual, and not
the universal, is substance, he is thinking of Plato. What he means to
deny is that the universal can exist on its own account, as Plato
thought. Nevertheless he agrees with Plato that the universal is the
real. When he says that the universal is not substance he means, as
against Plato, that it is not existent. What alone exists is the
individual thing, the compound of universal and particular. When he
says, or implies, that the universal is substance, he means that,
though it is not existent, it is real. His words are contradictory,
but his meaning is not. He has not expressed himself as clearly as he
should; that is all.
The further development of Aristotle's metaphysics depends upon his
doctrine of causation. By causation here, however, is meant a very
much wider conception {268} than what is understood by that term in
modern times. I have in previous lectures attempted to make clear the
distinction between causes and reasons. The cause of a thing does not
give any reason for it, and therefore does not explain it. The cause
is merely the mechanism by which a reason produces its consequence.
Death is caused by accident or disease, but these causes explain
nothing as to why death should be in the world at all. Now if we
accept this distinction, we may say that Aristotle's conception of
causation includes both what we have called causes and reasons.
Whatever is necessary, whether facts or principles, whether causes or
reasons, fully to understand the existence of a thing, or the
happening of an event, is included in the Aristotelian notion of
causation.
Taking causation in this wide sense, Aristotle finds that there are
four kinds of causes, the material, the efficient, the formal, and the
final cause. These are not alternative causes; it is not meant that,
to explain anything, one or other of the four must be present. In
every case of the existence or production of a thing all four causes
operate simultaneously. Moreover the same four causes are to be found
both in human and in cosmic production, in the making of manufactured
articles by man and in the production of things by nature. They are
more clearly and easily seen, however, in human production, from which
sphere, therefore, we select our example. The material cause of a
thing is the matter of which it is composed. It is the raw material
which becomes the thing. For example, in the making of a bronze statue
of Hermes, the bronze is the material cause of the statue. This
example might lead one to suppose {269} that Aristotle means by
material cause what we call matter, physical substance, such as brass,
iron, or wood. As we shall see later, this is not necessarily the
case, though it is so in the present instance. The efficient cause is
always defined by Aristotle as the cause of motion. It is the energy
or moving force required to bring about change. It must be remembered
that by motion Aristotle means not merely change of place but change
of any sort. The alteration of a leaf from green to yellow is just as
much motion, in his sense, as the falling of a stone. The efficient
cause, then, is the cause of all change. In the example taken, what
causes the bronze to become a statue, what produces this change, is
the sculptor. He is, therefore, the efficient cause of the statue. The
formal cause Aristotle defines as the substance and essence of the
thing. Now the essence of a thing is given in its definition. But the
definition is the explication of the concept. Therefore the formal
cause is the concept, or, as Plato would call it, the Idea of the
thing. Plato's Ideas thus reappear in Aristotle as formal causes. The
final cause is the end, purpose, or aim, towards which the movement is
directed. When a statue is being produced, the end of this activity,
what the sculptor aims at, is the completed statue itself. And the
final cause of a thing in general is the thing itself, the completed
being of the object.
We can see at once how much wider this conception of causation is than
the modern conception. If we take Mill's definition of a cause as the
best expression of modern scientific ideas, we find that he defines a
cause as the "invariable and unconditional antecedent of a
phenomenon." This cuts out final causes at once. For {270} the final
cause is the end, and is not an antecedent in time. It also does not
include formal causes. For we do not now think of the concept of a
thing as being part of its cause. This leaves us with only material
and efficient causes, and these correspond roughly to the modern
notions of matter and energy. Even the efficient causes of Aristotle,
however, appear on further consideration, to be excluded from the
modern idea of causation. For, though the efficient cause is the
energy which produces motion, modern science regards it as purely
mechanical energy, whereas Aristotle thinks of it, as we shall see, as
an ideal force, operating not from the beginning but from the end. But
it must not be supposed that, in saying that the modern idea of
causation excludes formal and final causes, we mean that Aristotle is
wrong in adding them, or that the modern idea is better than
Aristotle's. It is not a question of better and worse at all. Modern
science does not in any way deny the reality of formal and final
causes. It merely considers them to be outside its sphere. It is no
business of science whether they exist or not. As knowledge advances,
differentiation and division of labour occur. Science takes as its
province mechanical causes, and leaves formal and final causes to the
philosopher to explicate. Thus, for example, formal causes are not
considered by science because they are not, in the modern sense,
causes at all. They are what we have called reasons. If we are to
explain the existence of an object in the universe it may be necessary
to introduce formal causes, concepts, to show why the thing exists, to
show in fact its reasons. But science makes no attempt to explain the
existence of objects. It takes their {271} existence for granted, and
seeks to trace their history and their relations to each other.
Therefore it does not require formal causes. It seeks to work out the
mechanical view of the universe, and therefore considers only
mechanical causes. But Aristotle's theory, as being philosophy rather
than science, includes both the principles of mechanism and teleology.
It was not Aristotle's habit to propound his theories as if they were
something absolutely new, sprung for the first time out of his own
brain. In attacking any problem, his custom was to begin by
enumerating current and past opinions, to criticise them, to reject
what was valueless in them, to retain the residue of truth, and to add
to it his own suggestions and original ideas. The resultant of this
process was his own theory, which he thus represented, not as
absolutely new, but as a development of the views of his predecessors.
This course he follows also in the present instance. The first book of
the "Metaphysics" is a history of all previous philosophy, from Thales
to Plato, undertaken with the object of investigating how far the four
causes had been recognized by his predecessors. The material cause, he
says, had been recognized from the first. The Ionics believed in this
and no other cause. They sought to explain everything by matter,
though they differed among themselves as to the nature of the material
cause, Thales describing it as water, Anaximenes as air. Later
philosophers also gave different accounts of it, Heracleitus thinking
it was fire, Empedocles the four elements, Anaxagoras an indefinite
number of kinds of matter. But the point is that they all recognized
the necessity for a material cause of some sort to explain the
universe.
{272}
The earliest thinkers, then, the Ionics, assumed only this one cause.
But as thought advanced, says Aristotle, and other philosophers came
upon the scene, "the thing itself guided them." It was seen that a
second cause was necessary to explain the motion and becoming of
things. For matter itself does not produce its motion. Wood is not the
cause of its becoming a bed, nor is brass the cause of its becoming a
statue. Hence arose the idea of the efficient cause. The Eleatics did
not recognize it, for they denied motion, and for them, therefore, no
cause of motion could be assumed. But Parmenides, Aristotle thinks,
wavered on this point, somehow allowing vaguely the existence of a
second cause, which he denominated the hot and the cold. The reference
is, of course, to the second part of the poem of Parmenides. Other
philosophers clearly assumed an efficient cause, for they thought that
one element, for example, fire, is more active, that is, more
productive of motion, than others. Empedocles certainly attained to
the idea of an efficient cause, for he named as moving forces, harmony
and discord, love and hate. Anaxagoras also, used Nous as a moving
force.
Formal causes had, perhaps, been recognized by the Pythagoreans, for
numbers are forms. But they straightway degraded the formal cause to
the level of a material cause by declaring that number is the stuff or
matter of which things are made. Plato alone clearly saw the necessity
for the formal cause, for formal causes are, as we have seen, the same
as Plato's Ideas. But Plato's philosophy contains only two of the four
causes, namely the material and the formal, for Plato made all things
out of matter and the Ideas. Since the Ideas have in them {273} no
principle of motion, Plato's system contains no efficient cause. As
for final causes, Plato had indeed the vague idea that everything is
for the sake of the Good, but he makes no use of this conception and
does not develop it. Final causes were introduced into philosophy by
Anaxagoras, whose doctrine of the world forming mind was assumed to
explain the design and purpose which the universe exhibits. But as his
system developed he forgot about this, and used the Nous merely as a
piece of mechanism to explain motion, thus letting it sink into
nothing more than an efficient cause.
In the result, Aristotle finds that all four causes have been
recognized in greater or lesser degrees by his predecessors, and this,
in his opinion, greatly reinforces his own doctrine. But whereas
material and efficient causes have been clearly understood, his
predecessors had only vaguely foreshadowed and dimly perceived the
value of formal and final causes.
The next step in Aristotle's metaphysics is to reduce these four
principles to two, which he calls matter and form. This reduction
takes place by showing that formal cause, efficient cause, and final
cause, all melt into the single conception of form. In the first
place, the formal cause and the final cause are the same. For the
formal cause is the essence, the concept, the Idea, of the thing. Now
the final cause, or the end, is simply the realisation of the Idea of
the thing in actuality. What the thing aims at is the definite
expression of its form. It thus aims at its form. Its end, final
cause, is thus the same as its formal cause. Secondly, the efficient
cause is the same as the final cause. For the efficient cause is the
cause of becoming. The final cause is the end of {274} the becoming,
it is what it becomes. And, in Aristotle's opinion, what causes the
becoming is just that it aims at the end. The striving of all things
is towards the end, and exists because of the end. The end is thus
itself the cause of becoming or motion. That is to say, the final
cause is the real efficient cause. We may see this better by an
example. The end or final cause of the acorn is the oak. And it is the
oak which is the cause of the acorn's growth, which consists
essentially in a movement by which the acorn is drawn towards its end,
the oak. We may see this even more definitely in the case of human
productions, because here the striving towards an end is conscious,
whereas in nature it is unconscious or instinctive. The efficient
cause of the statue is the sculptor. It is he that moves the brass.
But what moves the sculptor, and causes him to act upon the brass, is
the idea of the completed statue in his mind. The idea of the end, the
final cause, is thus the real ultimate cause of the movement. Only, in
the case of human production, the idea of the end is actually present
in the sculptor's mind as a motive. In nature there is no mind in
which the end is conscious of itself, but nevertheless nature moves
towards the end, and the end is the cause of the movement. Thus the
three causes named all melt into a single notion, which Aristotle
calls the form of the thing. And this leaves only the material cause
unreduced to any other. So we are left with the single antithesis of
matter and form.
Now as matter and form are the fundamental categories of Aristotle's
philosophy, by means of which he seeks to explain the entire universe,
it is essential that we should thoroughly understand their
characteristics. {275} First of all, matter and form are inseparable.
We think of them as separate in order to understand them clearly. And
this is quite right, because they are opposite principles, and
therefore they are separable in thought. But they are never separable
in fact. There is no such thing as form without matter, or matter
without form. Every existent thing, that is, every individual object,
is a compound of matter and form. We may compare them in this respect
to the material and the shape of a thing, though we must be careful
not to think that form is merely shape. Geometry considers shapes as
if they existed by themselves. But, in fact, we know that there are no
such things as squares, circles, and triangles. There are only square
objects, circular objects, etc. And as there are no shapes without
objects, so there are no objects without shapes. We talk of things
being "shapeless," but this only means that their shape is irregular
or unusual. Some shape an object must have. Yet, though shape and
matter are inseparable in fact, they are opposite principles, and are
separable in thought. Geometry is quite right to treat shapes as if
they existed by themselves, but it is nevertheless dealing with mere
abstractions. Just in the same way, matter and form are never apart,
and to think of form by itself or matter by itself is a mere
abstraction. No such thing exists. In fact, to imagine that forms can
exist by themselves was just the mistake of which, as we have seen,
Aristotle accuses Plato. For the form is the Idea, and Plato imagined
that Ideas exist in a world of their own.
From this, too, we can see that the form is the universal, the matter
the particular. For the form is the Idea, and the Idea is the
universal. To say that form and {276} matter cannot exist apart is
thus the same as saying that the universal only exists in the
particular, which, as we have seen, is the fundamental note of
Aristotle's philosophy. But if we thus identify matter with the
particular element in things, we must be careful that we do not
confuse the particular with the individual. We often use these two
words as practically synonymous, and there is no harm in this, but
here we must be careful to separate them. For every individual is,
according to Aristotle, a compound of matter and form, of the
particular and the universal. And when we say that matter is the
particular, we mean, not that it is such a compound, but that it is
the absolutely particular which has no universal in it. But the
absolutely particular and isolated does not exist. A piece of gold,
for instance, only exists by virtue of its properties, yellowness,
heaviness, etc., and these qualities are just what it has in common
with other things. So that the particular, as such, has no existence,
but this is only the same as saying, what we have already said, that
matter has no existence apart from form.
A very natural mistake would be to suppose that by matter Aristotle
meant the same as we do, namely, physical substance, such as wood or
iron, and that by form he meant simply shape. Now although there is a
kinship in the ideas, these two pairs of ideas are far from identical.
Let us begin with matter. Our ordinary idea of matter as physical
substance is an absolute conception. That is to say, a thing which we
call material is absolutely, once and for all, matter. It is not
material from one point of view, and immaterial from another. In every
possible relation it is, and {277} remains, matter. Nor does it in
process of time cease to be matter. Brass never becomes anything but
matter. No doubt there are in nature changes of one sort of matter
into another, for example, radium into helium. And for all we know,
brass may become lead. But even so, it does not cease to be matter.
But Aristotle's conception of matter is a relative conception. Matter
and form are fluid. They flow into one another. The same thing, from
one point of view, is matter, from another, form. In all change,
matter is that which becomes, that upon which the change is wrought.
That is form towards which the change operates. What becomes is
matter. What it becomes is form. Thus wood is matter if considered in
relation to the bed. For it is what becomes the bed. But wood is form
if considered in relation to the growing plant. For it is what the
plant becomes. The oak is the form of the acorn, but it is the matter
of the oak furniture.
That matter and form are relative terms shows, too, that the form
cannot be merely the shape. For what is form in one aspect is matter
in another. But shape is never anything but shape. No doubt the shape
is part of the form, for the form in fact includes all the qualities
of the thing. But the shape is quite an unimportant part of the form.
For form includes organization, the relation of part to part, and the
subordination of all parts to the whole. The form is the sum of the
internal and external relations, the ideal framework, so to speak,
into which the thing is moulded. Form also includes function. For it
includes the final cause. Now the function of a thing is just what the
thing is for. And what it is for is the same as its end, or final
cause. {278} Therefore function is included in form. For example, the
function of a hand, its power of gripping, is part of its form. And
therefore, if it loses its function by being cut off from the arm, it
likewise loses its form. Even the dead hand, of course, has some form,
for every individual object is a compound of matter and form. But it
has lost the highest part of its form, and relatively to the living
hand it is mere matter, although, relatively to the flesh and bones of
which it is composed, it is still form. Clearly, then, form is not
merely shape. For the hand cut off does not lose its shape.
The form includes all the qualities of the thing. The matter is what
has the qualities. For the qualities are all universals. A piece of
gold is yellow, and this means simply that it has this in common with
other pieces of gold, and other yellow objects. To say that anything
has a quality is immediately to place it in a class. And what the
class has in common is a universal. A thing without qualities cannot
exist, nor qualities without a thing. And this is the same as saying
that form and matter cannot exist separately.
The matter, then, is the absolutely formless. It is the substratum
which underlies everything. It has, in itself, no character. It is
absolutely featureless, indefinite, without any quality. Whatever
gives a thing definiteness, character, quality, whatever makes it a
this or that, is its form. Consequently, there are no differences
within matter. One thing can only differ from another by having
different qualities. And as matter has no qualities, it has no
difference. And this in itself shows that the Aristotelian notion of
matter is not the same as our notion of physical substance. For,
according {279} to our modern usage, one kind of matter differs from
another, as brass from iron. But this is a difference of quality, and
for Aristotle all quality is part of the form. So in his view the
difference of brass from iron is not a difference of matter, but a
difference of form. Consequently, matter may become anything,
according to the form impressed upon it. It is thus the possibility of
everything, though it is actually nothing. It only becomes something
by the acquisition of form. And this leads directly to a most
important Aristotelian antithesis, that between potentiality and
actuality. Potentiality is the same as matter, actuality as form. For
matter is potentially everything. It may become everything. It is not
actually anything. It is a mere potentiality, or capacity of becoming
something. But whatever gives it definiteness as a this or that,
whatever makes it an actual thing, is its form. Thus the actuality of
a thing is simply its form.
Aristotle claims, by means of the antithesis of potentiality and
actuality, to have solved the ancient problem of becoming, a riddle,
propounded by the Eleatics, which had never ceased to trouble Greek
thinkers. How is becoming possible? For being to pass into being is
not becoming, for it involves no change, and for not-being to pass
into being is impossible, since something cannot come out of nothing.
For Aristotle, the sharp line drawn between not-being and being does
not exist. For these absolute terms he substitutes the relative terms
potentiality and actuality, which shade off into each other.
Potentiality in his philosophy takes the place of not-being in
previous systems. It solves the riddle because it is not an absolute
not-being. It is {280} not-being inasmuch as it is actually nothing,
but it is being because it is potential being. Becoming, therefore,
does not involve the impossible leap from nothing to something. It
involves the transition from potential to actual being. All change,
all motion, is thus the passage of potentiality into actuality, of
matter into form.
Since matter is in itself nothing, a bare unrealised capacity, while
form is actuality, the completed and perfected being, it follows that
form is something higher than matter. But matter is what becomes form.
In order of time, therefore, matter is earlier, form later. But in
order of thought, and in reality, it is otherwise. For when we say
that matter is the potentiality of what it is to become, this implies
that what it is to become is already present in it ideally and
potentially, though not actually. The end, therefore, is already
present in the beginning. The oak is in the acorn, ideally, otherwise
the oak could never come out of it. And since all becoming is towards
the end, and would not take place but for the end, the end is the
operative principle and true cause of becoming. Motion is produced not
by a mechanical propulsive force, pushing from behind, so to speak,
but by an ideal attractive force, drawing the thing towards its end,
as a piece of iron is drawn to the magnet. It is the end itself which
exerts this force. And, therefore, the end must be present at the
beginning, for if it were not present it could exert no force. Nay,
more. It is not only present in the beginning, it is anterior to it.
For the end is the cause of the motion, and the cause is logically
prior to its consequence. The end, or the principle of form, is thus
the absolute first in thought and reality, though it may be the last
in time. If, then, {281} we ask what, for Aristotle, is that ultimate
reality, that first principle, from which the entire universe flows,
the answer is, the end, the principle of form. And as form is the
universal, the Idea, we see that his fundamental thesis is the same as
Plato's. It is the one thesis of all idealism, namely, that thought,
the universal, reason, is the absolute being, the foundation of the
world. Where he differs from Plato is in denying that form has any
existence apart from the matter in which it exhibits itself.
Now all this may strike the unsophisticated as very strange. That the
absolute being whence the universe flows should be described as that
which lies at the end of the development of the universe, and that
philosophy should proceed to justify this by asserting that the end is
really prior to the beginning, this is so far removed from the common
man's mode of thought, that it may appear mere paradox. It is,
however, neither strange nor paradoxical. It is essentially sound and
true, and it seems strange to the ordinary man only because it
penetrates so much deeper into things than he can. This thought is, in
fact, essential to a developed idealism, and till it is grasped no
advance can be made in philosophy. Whether it is understood is,
indeed, a good test of whether a man has any talent for philosophy or
not. The fact is that all philosophies of this sort regard time as
unreal, as an appearance. This being so, the relation of the absolute
being, or God, to the world cannot be a relation of time at all. The
common man's idea is that, if there is a first principle or God at
all, He must have existed before the world began, and then, somehow,
perhaps billions of years ago, something happened as a {282} result of
which the world came into being. The Absolute is thus conceived as the
cause, the world as the effect, and the cause always precedes its
effect in time. Or if, on the other hand, we think that the world
never had a beginning, the ordinary man's thought would lead him to
believe that, in that case, it is no longer necessary to assume a
first principle at all. But if time is a mere appearance, this whole
way of looking at things must be wrong. God is not related to the
world as cause to effect. It is not a relation of time at all. It is a
_logical_ relation. God is rather the logical premise, of which the
world is the conclusion, so that, God granted, the world follows
necessarily, just as, the premises granted, the conclusion follows.
This is the reason why, in discussing Plato, we said that it must be
possible to _deduce_ the world from his first principle. If the
Absolute were merely the cause of the world in time, it would not
explain the world, for, as I have so often pointed out, causes explain
nothing. But if the world be deducible from the Absolute, the world is
explained, a reason, not a cause, is given for it, just as the
premises constitute the reason for the conclusion. Now the conclusion
of a syllogism follows from the premises, that is, the premises come
first, the conclusion second. But the premise only comes first in
thought, not in time. It is a logical succession, not a
time-succession. Just in the same way, the Absolute, or in Aristotle's
language, the form, is logically first, but is not first in order of
time. And though it is the end, it is in thought the absolute
beginning, and is thus the foundation of the world, the first
principle from which the world flows. The objection may be, taken that
if the relation of the {283} Absolute to the world is not a
time-relation, then it can no more be the end than the beginning. This
objection is, as we shall see, a misunderstanding of Aristotle's
philosophy. Although things in time strive towards the end, yet the
absolute end is not in time at all, or, in other words, the end is
never reached. Its relation to the world as end is just as much a
logical, and not a time-relation, as its relation to the world as
beginning or absolute prius. As far as time is concerned, the universe
is without beginning or end.
As the world-process is a continual elevation of matter into higher
and higher forms, there results the conception that the universe
exhibits a continuous scale of being. That is higher in the scale in
which form predominates, that lower in which matter outweighs form. At
the bottom of the scale will be absolutely formless matter, at the
top, absolutely matterless form. Both these extremes, however, are
abstractions. Neither of them exists, because matter and form cannot
be separated. Whatever exists comes somewhere between the two, and the
universe thus exhibits a process of continuous gradations. Motion and
change are produced by the effort to pass from the lower to the higher
under the attractive force of the end.
That which comes at the top of the scale, absolute form, is called by
Aristotle, God. And the definitions of God's character follow from
this as a matter of course. First, since form is actuality, God alone
is absolutely actual. He alone is real. All existent things are more
or less unreal. The higher in the scale are the more real, as
possessing more form. The scale of being is thus also a scale of
reality, shading off through infinite gradations {284} from the
absolutely real, God, to the absolutely unreal, formless matter.
Secondly, since the principle of form contains the formal, the final,
and the efficient causes, God is all these. As formal cause, He is the
Idea. He is essentially thought, reason. As final cause, He is the
absolute end. He is that to which all beings strive. Each being has no
doubt its own end in itself. But as absolute end, God includes all
lower ends. And as the end of each thing is the completed perfection
of the thing, so, as absolute end, God is absolute perfection. Lastly,
as efficient cause, God is the ultimate cause of all motion and
becoming. He is the first mover. As such, He is Himself unmoved. That
the first mover should be itself unmoved is a necessary consequence of
Aristotle's conception of it as end and form. For motion is the
transition of a thing towards its end. The absolute end can have no
end beyond it, and therefore cannot be moved. Likewise motion is the
passage of matter into form. Absolute form cannot pass into any higher
form, and is therefore unmoved. But the argument which Aristotle
himself more frequently uses to establish the immovability of the
first mover is that, unless we so conceive it, no cause of motion
appears. The moving object is moved perhaps by another moving object.
The motion of the latter demands a further cause. If this further
cause is itself moving, we must again ask for the cause of its motion.
If this process goes on for ever, then motion is unexplained, and no
real cause of it has been shown. The real and ultimate cause must
therefore be unmoved.
This last argument sounds as if Aristotle is now thinking in terms of
mechanism. It sounds as if he meant that {285} the first mover is
something at the beginning of time, which, so to speak, gave things a
push to start them off. This is not what Aristotle means. For the true
efficient cause is the final cause. And God is the first mover only in
His character as absolute end. As far as time is concerned, neither
the universe, nor the motion in it, ever had any beginning. Every
mechanical cause has its cause in turn, and so _ad infinitum_. God is
not a first cause, in our sense, that is, a first mechanical cause
which existed before the world, and created it. He is a teleological
cause working from the end. But as such, He is logically prior to all
beginning, and so is the first mover. And just as the universe has no
beginning in time, so it has no end in time. It will go on for ever.
Its end is absolute form, but this can never be reached, because if it
were, this would mean that absolute form would exist, whereas we have
seen that form cannot exist apart from matter.
God is thought. But the thought of what? As absolute form, he is not
the form of matter, but the form of form. His matter, so to speak, is
form. Form, as the universal, is thought. And this gives us
Aristotle's famous definition of God as "the thought of thought." He
thinks only his own self. He is at once the subject and the object of
his thought. As mortal men think material things, as I now think the
paper on which I write, so God thinks thought. In more modern terms,
he is self-consciousness, the absolute subject-object. That God should
think anything other than thought is inconceivable, because the end of
all other thought is outside the thought itself. If I think this
paper, the end of my thought, the paper, is outside me. But the
thought of {286} God, as the absolute end, cannot have any end outside
itself. Were God to think anything else than thought, he would be
determined by that which is not himself. By way of further expression
of the same idea, Aristotle passes into figurative language. God, he
says, lives in eternal blessedness, and his blessedness consists in
the everlasting contemplation of his own perfection.
A modern will naturally ask whether Aristotle's God is personal. It
does not do to be very dogmatic upon the point. Aristotle, like Plato,
never discusses the question. No Greek ever did. It is a modern
question. What we have to do, then, is to take the evidence on both
sides. The case for personality is that the language Aristotle uses
implies it. The very word God, used instead of the Absolute, or form,
conveys the idea of personality. And when he goes on to speak of God
living in eternal blessedness, these words, if taken literally, can
mean nothing except that God is a conscious person. If we say that
this language is merely figurative, it may be replied that Aristotle
on principle objects to figurative language, that he frequently
censures Plato for using it, that what he demands and sets out to
supply is exact, literal, scientific terminology, and that he is not
likely to have broken his own canons of philosophic expression by
using merely poetical phrases.
To see the other side of the case, we must first ask what personality
means. Now without entering into an intricate discussion of this most
elusive idea, we may answer that personality at any rate implies an
_individual_ and _existent_ consciousness. But, in the first place, God is
absolute form, and form is the universal. What is universal, with no
particular in it, cannot be an individual. {287} God, therefore,
cannot be individual. Secondly, form without matter cannot exist. And
as God is form without matter, he cannot be called existent, though he
is absolutely real. God, therefore, is neither existent nor
individual. And this means that he is not a person. To degrade the
real to the level of the existent, to convert the universal into the
individual, is exactly the fault for which Aristotle blames Plato. It
is exactly the fault which it was the whole object of his philosophy
to remedy. If he thought that God is a person, he committed the same
fault himself in an aggravated form.
We have, then, two hypotheses, both of which involve that Aristotle
was guilty of some inconsistency. If God is not a person, then
Aristotle's language is figurative, and his use of such language is
inconsistent with his rooted objection to its use. This, however, is,
after all, merely an inconsistency of language, and not of thought. It
does not mean that Aristotle really contradicted himself. It merely
means that, though he set himself to express his philosophy in
technical scientific terms, and to exclude figurative language, yet he
found himself compelled in a few passages to make use of it. There are
some metaphysical ideas so abstract, so abstruse, that it is almost
impossible to express them at all without the use of figures of
speech. Language was made by common men for common purposes, and this
fact often forces the philosopher to use terms which he knows only
figure forth his meaning without accurately expressing it. Perhaps
every philosophy in the world finds itself sometimes under this
necessity, and, if Aristotle did so, and was thereby technically
inconsistent with himself, it is no wonder, and involves no serious
blame upon him.
{288}
But the other hypothesis, that God is a person, means that Aristotle
committed a contradiction, not merely in words, but in thought, and
not merely as regards some unimportant detail, but as regards the
central thesis of his system. It means that he stultified himself by
making his conception of God absolutely contradict the essentials of
his system. For what is the whole of Aristotle's philosophy, put in a
nutshell? It is that the Absolute is the universal, but that the
universal does not exist apart from the particular. Plato supplied the
thought of the first clause of the sentence. Aristotle added the last
clause, and it is the essential of his philosophy. To assert that God,
the absolute form, exists as an individual, is flatly to contradict
this. It is not likely that Aristotle should have contradicted himself
in so vital a matter, and in a manner which simply means that his
system falls to the ground like a house of cards.
My conclusion, then, is that it was not Aristotle's intention that
what he calls God should be regarded as a person. God is thought, but
not subjective thought. He is not thought existent in a mind, but
objective thought, real on its own account, apart from any mind which
thinks it, like Plato's Ideas. But Plato's mistake was to suppose that
because thought is real and objective, it must exist. Aristotle avoids
this error. The absolute thought is the absolutely real. But it does
not exist. With the concept of God the metaphysics of Aristotle
closes.
4. Physics, or the Philosophy of Nature.
The existent universe is a scale of being lying between the two
extremes of formless matter and matterless form. But this must not be
merely asserted, as a general {289} principle. It must be carried out
in detail. The passage of matter into form must be shown in its
various stages in the world of nature. To do this is the object of
Aristotle's Physics, or philosophy of nature.
If nature is to be understood, we must keep in mind certain general
points of view. In the first place, since form includes end, the
entire world-process, as passage of matter into form, is essentially
movement towards ends. Everything in nature has its end and function.
Nothing is purposeless. Nature seeks everywhere to attain the best
possible. Everywhere we find evidences of design and of rational plan.
Aristotle's philosophy of nature is essentially teleological. This
does not, however, exclude the principle of mechanism, and to
investigate mechanical causes is part of the duty of science. But
mechanical causes turn out in the end to be teleological, because the
true efficient cause is the final cause.
But if nothing in nature is aimless or useless, this is not to be
interpreted in a narrow anthropocentric spirit. It does not mean that
everything exists for the use of man, that the sun was created to give
him light by day, the moon by night, and that plants and animals exist
only for his food. It is true that, in a certain sense, everything
else sublunary is _for_ man. For man is the highest in the scale of
beings in this terrestrial sphere, and therefore as the higher end, he
includes all lower ends. But this does not exclude the fact that lower
beings have each its own end. They exist for themselves and not for
us.
Another mistake which we must avoid is to suppose that the design in
nature means that nature is conscious of her designs, or, on the other
hand, that there is any {290} existent consciousness outside the world
which governs and controls it. The latter supposition is excluded by
the fact that God is not an existent conscious person, the former by
its own inherent absurdity. The only being upon this earth who is
conscious of his ends is man. Such animals as bees and ants appear to
work rationally, and their activities are clearly governed by design.
But it is not to be supposed that they are reasoning beings. They
attain their ends instinctively. And when we come to inorganic matter,
we find that even here its movements are purposive, but no one could
suppose them deliberate and conscious. These manifold activities of
lower nature are indeed the work of reason, but not of an existent or
self-conscious reason. And this means that instinct, and even
mechanical forces such as gravitation are, in their essence, reason.
It is not that they are created by reason, but that they are reason,
exhibiting itself in lower forms. In commenting upon Plato's dualism
of sense and reason, I remarked that any true philosophy, though
recognizing the distinction between sense and reason, must yet find
room for their identity, and must show that sense is but a lower form
of reason. This idea Aristotle thoroughly understood, and sought to
show, not merely that sense is reason, but even that the activities of
inorganic matter, such as gravitation, are so. In the result, nature,
though working through reason, is not conscious of the fact, does so
blindly and instinctively, and is compared to a creative artist, who
forms beautiful objects by instinct, or, as we should say, by
inspiration, without setting before his mind the end to be attained or
the rules to be observed in order to attain it.
{291}
In the process of nature, it is always form which impels, matter which
retards and obstructs. The entire world-movement is the effort of form
to mould matter, but, just because matter has in itself a power of
resistance, this effort does not always succeed. This is the reason
why form cannot exist without matter, because it can never wholly
overcome the clogging activity of matter, and therefore matter can
never be wholly moulded into form. And this explains, too, the
occasional occurrence in nature of freaks, monstrosities, abortions,
and unnatural births. In these the form has failed to mould the
matter. Nature has failed to attain her ends. Science, therefore,
should study the normal and natural rather than the abnormal and
monstrous. For it is in the normal that the ends of nature are to be
seen, and through them alone nature can be understood. Aristotle is
fond of using the words "natural" and "unnatural," but he uses them
always with this special meaning. That is natural which attains its
end, that in which the form successfully masters the matter.
No doctrine of physics can ignore the fundamental notions of motion,
space, and time. Aristotle, therefore, finds it necessary to consider
these. Motion is the passage of matter into form, and it is of four
kinds. The first is motion which affects the substance of a thing,
origination and decease. Secondly, change of quality. Thirdly, change
of quantity, increase and decrease. Fourthly, locomotion, change of
place. Of these, the last is the most fundamental and important.
Aristotle rejects the definition of space as the void. Empty space is
an impossibility. Hence, too, he disagrees with the view of Plato and
the Pythagoreans that {292} the elements are composed of geometrical
figures. And connected with this is his repudiation of the mechanical
hypothesis that all quality is founded upon quantity, or upon
composition and decomposition. Quality has a real existence of its
own. He rejects, also, the view that space is a physical thing. If
this were true, there would be two bodies occupying the same place at
the same time, namely the object and the space it fills. Hence there
is nothing for it but to conceive space as limit. Space is, therefore,
defined as the limit of the surrounding body towards what is
surrounded. As we shall see later, in another connexion, Aristotle did
not regard space as infinite.
Time is defined as the measure of motion in regard to what is earlier
and later. It thus depends for its existence upon motion. If there
were no change in the universe, there would be no time. And since it
is the measuring or counting of motion, it also depends for its
existence upon a counting mind. If there were no mind to count, there
could be no time. This presents difficulties to us, if we conceive
that there was a time when conscious beings did not exist. But this
difficulty is non-existent for Aristotle, who believed that men and
animals have existed from all eternity. The essentials of time,
therefore, are two: change and consciousness. Time is the succession
of thoughts. If we object that the definition is bad because
succession already involves time, there is doubtless no answer
possible.
As to the infinite divisibility of space and time, and the riddles
proposed thereupon by Zeno, Aristotle is of opinion that space and
time are potentially divisible {293} _ad infinitum_, but are not
actually so divided. There is nothing to prevent us from going on for
ever with the process of division, but space and time are not given in
experience as infinitely divided.
After these preliminaries, we can pass on to consider the main subject
of physics, the scale of being. We should notice, in the first place,
that it is also a scale of values. What is higher in the scale of
being is of more worth, because the principle of form is more advanced
in it. It constitutes also a theory of development, a philosophy of
evolution. The lower develops into the higher. It does not, however,
so develop in time. That the lower form passes in due time into a
higher form is a discovery of modern times. Such a conception was
impossible for Aristotle. For him, genus and species are eternal. They
have neither beginning nor end. Individual men are born and die, but
the species man never dies, and has always existed upon the earth. The
same is true of plants and animals. And since man has always existed,
he cannot have evolved in time from a lower being. There is no room
here for Darwinism. In what sense, then, is this a theory of
development or evolution? The process involved is not a time-process,
it is a logical process, and the development is a logical development.
The lower always contains the higher potentially. The man is in the
ape ideally. The higher, again, contains the lower actually. The man
is all that the ape is, and more also. What is merely implicit in the
lower form is explicit in the higher. The form which is dimly seen
struggling to light in the lower, has realized itself in the higher.
The higher is the same thing as the lower, but it is the same thing in
a more {294} evolved state. The higher presupposes the lower and rests
upon it as foundation. The higher is the form of which the lower is
the matter. It actually is what the lower is struggling to become.
Hence the entire universe is one continuous chain. It is a process;
not a time-process, but an eternal process. The one ultimate reality,
God, reason, absolute form, eternally exhibits itself in every stage
of its development. All the stages, therefore, must exist for ever
side by side.
Now the form of a thing is its organization. Hence to be higher in the
scale means to be more organized. The first distinction, therefore,
with which nature presents us is between the organic and the
inorganic. Aristotle was the discoverer of the idea of organism, as he
was also the inventor of the word. At the bottom of the scale of
being, therefore, is inorganic matter. Inorganic matter is the nearest
existent thing to absolutely formless matter, which, of course, does
not exist. In the inorganic world matter preponderates to such an
extent as almost to overwhelm form, and we can only expect to see the
universal exhibiting itself in it in a vague and dim way. What, then,
is its form? And this is the same as asking what its function, end, or
essential activity is. The end of inorganic matter is merely external
to it. Form has not truly entered into it at all, and remains outside
it. Hence the activity of inorganic matter can only be to move in
space towards its external end. This is the explanation of what we, in
modern times, call gravitation. But, according to Aristotle, every
element has its peculiar and natural motion; its end is conceived
merely spatially, and its activity is to move towards its "proper
place," and, having thus reached its end, it rests. The natural {295}
movement of fire is up. We may call this a principle of levitation, as
opposed to gravitation. Aristotle has been the subject of cheap
criticism on account of his frequent use of the words "natural" and
"unnatural." [Footnote 15] It is said that he was satisfied to explain
the operations of nature by simply labelling them "natural." If you
ask a quite uneducated person why heavy bodies fall, he may quite
possibly reply, "Oh! _naturally_ they fall." This simply means that
the man has never thought about the matter at all, and thinks whatever
is absolutely familiar to him is "natural" and needs no explanation.
It is like the feminine argument that a thing is so, "because it is."
It is assumed that Aristotle was guilty of a like futility. This is
not the case. His use of the word "natural" does not indicate lack of
thought. There is a thought, an idea, here. No doubt he was quite
wrong in many of his facts. Thus there is no such principle as
levitation in the universe. But there is a principle of gravitation,
and when he explains this by saying it is "natural" for earth to move
downwards, he means, not that the fact is familiar, but that the
principle of form, or the world-reason, can only exhibit itself here
so dimly as to give rise to a comparatively aimless and purposeless
movement in a straight line. Not absolutely purposeless, however,
because nothing in the world is such, and the purpose here is simply
the movement of matter towards its end. This may or may not be a true
explanation of gravity. But has anybody since ever explained it
better?
[Footnote 15: See, _e.g._ Sir Alexander Grant's _Aristotle_ in the
Ancient Classics for English Readers Series (Blackwood), pages
119-121.]
This gives us, too, the clue to the distinction between {296} the
inorganic and the organic. If inorganic matter is what has its end
outside itself, organic matter will be what has its end within itself.
This is the essential character of an organism, that its end is
internal to it. It is an inward self-developing principle. Its
function, therefore, can only be the actualisation, the
self-realization of this inward end. Whereas, therefore, inorganic
matter has no activity except spatial movement, organic matter has for
its activity growth, and this growth is not the mere mechanical
addition of extraneous matter, as we add a pound of tea to a pound of
tea. It is true growth from within. It is the making outward of what
is inward. It is the making explicit of what is implicit. It is the
making actual of what is potential in the embryo organism.
The lowest in the scale of being is thus inorganic matter, and above
it comes organic matter, in which the principle of form becomes real
and definite as the inward organization of the thing. This inward
organization is the life, or what we call the soul, of the organism.
Even the human soul is nothing but the organization of the body. It
stands to the body in the relation of form to matter. With organism,
then, we reach the idea of living soul. But this living soul will
itself have lower and higher grades of being, the higher being a
higher realization of the principle of form. As the essential of
organism is self-realization, this will express itself first as
self-preservation. Self-preservation means first the preservation of
the individual, and this gives the function of nutrition. Secondly, it
means preservation of the species, and this gives the function of
propagation. The lowest grade in the organic kingdom will, therefore,
be {297} those organisms whose sole functions are to nourish
themselves, grow, and propagate their kind. These are plants. And we
may sum up this by saying that plants possess the nutritive soul.
Aristotle intended to write a treatise upon plants, which intention,
however, he never carried out. All that we have from him on plants is
scattered references in his other books. Had the promised treatise
been forthcoming, we cannot doubt what its plan would have been.
Aristotle would have shown, as he did in the case of animals, that
there are higher and lower grades of organism within the plant
kingdom, and he would have attempted to trace the development in
detail through all the then known species of plants.
Next above plants in the scale of being come animals. Since the higher
always contains the lower, but exhibits a further realization of form
peculiar to itself, animals share with plants the functions of
nutrition and propagation. What is peculiar to them, the point in
which they rise above plants, is the possession of sensation.
Sense-perception is therefore the special function of animals, and
they possess, therefore, the nutritive and the sensitive souls. With
sensation come pleasure and pain, for pleasure is a pleasant
sensation, and pain the opposite. Hence arises the impulse to seek the
pleasant and avoid the painful. This can only be achieved by the power
of movement. Most animals, accordingly, have the power of locomotion,
which is not possessed by plants, because they do not require it,
since they are not sensitive to pleasure and pain. In his books upon
animals Aristotle attempts to carry out the principle of development
in detail, showing what are the higher, and what the lower, animal
organisms. This he connects with the {298} methods of propagation
employed by different animals. Sex-generation is the mark of a higher
organism than parthenogenesis.
The scale of being proceeds from animals to man. The human organism,
of course, contains the principles of all lower organisms. Man
nourishes himself, grows, propagates his kind, moves about, and is
endowed with sense-perception. But he must have in addition his own
special function, which constitutes his advance beyond the animals.
This is reason. Reason is the essential, the proper end and activity
of man. His soul is nutritive, sensitive, and rational. In man,
therefore, the world-reason which could only appear in inorganic
matter as gravitation and levitation, in plants as nutrition, in
animals as sensation, appears at last in its own proper form, as what
it essentially is, reason. The world-reason, so long struggling
towards the light, has reached it, has become actual, has become
existent, in man. The world-process has attained its proximate end.
Within human consciousness there are lower and higher grades, and
Aristotle has taken great pains to trace these from the bottom to the
top. These stages of consciousness are what are ordinarily called
"faculties." But Aristotle notes that it is nonsense to talk, as Plato
did, of the "parts" of the soul. The soul, being a single indivisible
being, has no parts. They are different aspects of the activity of one
and the same being; different stages of its development. They can no
more be separated than the convex and concave aspects of a curve. The
lowest faculty, if we must use that word, is sense-perception. Now
what we perceive in a thing is its qualities. Perception tells us that
a piece of gold is {299} heavy, yellow, etc. The underlying substratum
which supports the qualities cannot be perceived. This means that the
matter is unknowable, the form knowable, for the qualities are part of
the form. Sense-perception, therefore, takes place when the object
stamps its form upon the soul. This is important for what it implies
rather than what it states. It shows the thoroughly idealistic trend
of Aristotle's thought. For if the form is what is knowable in a
thing, the more form there is, the more knowable it will be. Absolute
form, God, will be the absolutely knowable. That the Absolute is what
alone is completely knowable, intelligible, and comprehensible, and
the finite and material comparatively unknowable, is a point of view
essential to idealism, and stands in marked contrast to the popular
idea of rationalism that the Absolute is unknowable, and matter
knowable. For idealism, the Absolute is reason, thought. What can be
more thoroughly intelligible than reason? What can thought
understand, if not thought? This, of course, is not stated by
Aristotle. But it is implied in his theory of sense-perception.
Next in the scale above the senses comes the common sense. This has
nothing to do with what we understand by that phrase in every-day
language. It means the central sensation-ganglion in which isolated
sensations meet, are combined, and form a unity of experience. We saw,
in considering Plato, that the simplest kind of knowledge, such as,
"this paper is white," involves, not only isolated sensations, but
their comparison and contrast. Bare sensations would not even make
objects. For every object is a combined bundle of sensations. What
thus combines the various sensations, and in {300} particular those
received from different sense-organs, what compares and contrasts
them, and turns them from a blind medley of phantasms into a definite
experience, a single cosmos, is the common sense. Its organ is the
heart.
Above the common sense is the faculty of imagination. By this
Aristotle means, not the creative imagination of the artist, but the
power, which everyone possesses, of forming mental images and
pictures. This is due to the excitation in the sense-organ continuing
after the object has ceased to affect it.
The next faculty is memory. This is the same as imagination, except
that there is combined with the image a recognition of it as a copy of
a past sense-impression.
Recollection, again, is higher than memory. Memory images drift
purposelessly through the mind. Recollection is the deliberate evoking
of memory-images.
From recollection we pass to the specifically human faculty of reason.
But reason itself has two grades. The lower is called passive reason,
the higher active reason. The mind has the power of thought before it
actually thinks. This latent capacity is passive reason. The mind is
here like a smooth piece of wax which has the power to receive
writing, but has not received it. The positive activity of thought
itself is active reason. The comparison with wax must not mislead us
into supposing that the soul only receives its impressions from
sensation. It is pure thought which writes upon the wax.
Now the sum of the faculties in general we call the soul. And the
soul, we saw, is simply the organization {301} or form, of the body.
As form is inseparable from matter, the soul cannot exist without the
body. It is the function of the body. It is to the body what sight is
to the eye. And in the same sense Aristotle denies the doctrine of
Pythagoras and Plato that the soul reincarnates itself in new bodies,
particularly in the bodies of animals. What is the function of one
thing cannot become the function of another. Exactly what the soul is
to the body the music of the flute is to the flute itself. It is the
form of which the flute is the matter. It is, to speak metaphorically,
the soul of the flute. And you might as well talk, says Aristotle, of
the art of flute-playing becoming reincarnate in the blacksmith's
anvil, as of the soul passing into another body. This would seem also
to preclude any doctrine of immortality. For the function perishes
with the thing. We shall return to that point in a moment. But we may
note, meanwhile, that Aristotle's theory of the soul is not only a
great advance upon Plato's, but is a great advance upon popular
thinking of the present day. The ordinary view of the soul, which was
Plato's view, is that the soul is a sort of thing. No doubt it is
non-material and supersensuous. But still it is a thing; it can be put
into a body and taken out of it, as wine can be put into or taken out
of a bottle. The connection between body and soul is thus purely
mechanical. They are attached to each other by no necessary bond, but
rather by force. They have, in their own natures, no connexion with
each other, and it is difficult to see why the soul ever entered a
body, if it is in its nature something quite separate. But Aristotle's
view is that the soul, as form of the body, is not separable from it.
You cannot have {302} a soul without a body. The connection between
them is not mechanical, but organic. The soul is not a thing which
comes into the body and goes out of it. It is not a thing at all. It
is a function.
But to this doctrine Aristotle makes an exception in favour of the
active reason. All the lower faculties perish with the body, including
the passive reason. Active reason is imperishable and eternal. It has
neither beginning nor end. It comes into the body from without, and
departs from it at death. God being absolute reason, man's reason
comes from God, and returns to him, after the body ceases to function.
But before we hail this as a doctrine of personal immortality, we had
best reflect. All the lower faculties perish at death, and this
includes memory. Now memory is an essential of personality. Without
memory our experiences would be a succession of isolated sensations,
with no connecting link. What connects my last with my present
experience is that my last experience was "mine." To be mine it must
be remembered. Memory is the string upon which isolated experiences
are strung together, and which makes them into that unity I call
myself, my personality. If memory perishes, there can be no personal
life. And it must be remembered that Aristotle does not mean merely
that, in that future life--if we persist in calling it such--the
memory of this life is obliterated. He means that in the future life
itself reason has no memory of itself from moment to moment. We cannot
be dogmatic about what Aristotle himself thought. He seems to avoid
the question. He probably shrank from disturbing popular beliefs on
the subject. We have, at any rate, no definite pronouncement from
{303} him. All we can say is that his doctrine does not provide the
material for belief in personal immortality. It expressly removes the
material in that it denies the persistence of memory. Moreover, if
Aristotle really thought that reason is a thing, which goes in and out
of the body, an exception, in the literal sense, to his general
doctrine of soul, all we can say is that he undergoes a sudden drop in
the philosophic scale. Having propounded so advanced a theory, he
sinks back to the crude view of Plato. And as this is not likely, the
most probable explanation is that he is here speaking figuratively,
perhaps with the intention of propitiating the religious and avoiding
any rude disturbance of popular belief. If so, the statements that
active reason is immortal, comes from God, and returns to God, mean
simply that the world-reason is eternal, and that man's reason is the
actualization of this eternal reason, and in that sense "comes from
God" and returns to Him. We may add, too, that since God, though real,
is not to be regarded as an existent individual, our return to Him
cannot be thought as a continuation of individual existence. Personal
immortality is inconsistent with the fundamentals of Aristotle's
system. We ought not to suppose that he contradicted himself in this
way. Yet if Aristotle used language which seems to imply personal
immortality, this is neither meaningless nor dishonest. It is as true
for him as for others that the soul is eternal. But eternal does not
mean everlasting in time. It means timeless. And reason, even our
reason, is timeless. The soul has eternity in it. It is "eternity in
an hour." And it is this which puts the difference between man and the
brutes.
{304}
We have traced the scale of being from inorganic matter, through
plants and animals, to man. What then? What is the next step? Or does
the scale stop there? Now there is a sort of break in Aristotle's
system at this point, which has led many to say that man is the top of
the scale. The rest of Aristotle's physics deal with what is outside
our earth, such as the stars and planets. And they deal with them
quite as if they were a different subject, having little or nothing to
do with the terrestrial scale of being which we have been considering.
But here we must not forget two facts. The first is that Aristotle's
writings have come down to us mutilated, and in many cases unfinished.
The second is that Aristotle had a curious habit of writing separate
monographs on different parts of his system, and omitting to point out
any connexion between them, although such a connexion undoubtedly
exists.
Now although Aristotle himself does not say it, there are several good
reasons for thinking that the true interpretation of his meaning is
that the scale of being does not stop at man, that there is no gap in
the chain here, but that it proceeds from man through planets and
stars--which Aristotle, like Plato, regarded as divine beings--right
up to God himself. In the first place, this is required by the logic
of his system. The scale has formless matter at the bottom and
matterless form at the top. It should proceed direct from one to the
other. It is essential to his philosophy that the universe is a single
continuous chain. There is no place for such a hiatus between man and
the higher beings. Secondly, it is not as if terrestrial life formed a
scale, and celestial beings were all on a par, having among themselves
no {305} scale of higher and lower. This is not the case. The heavenly
bodies have grades among themselves. The higher are related to the
lower as form to matter. Thus stars are higher than planets. So that
if we suppose that evolution stops at man, what we have is a gap in
the middle, a scale below it, and a scale above it. It is like a
bridge over a sheet of water, the two ends of which are intact, but
which is broken down in the middle. The natural completion of this
scheme involves the filling up of the gap. Thirdly, we have another
very important piece of evidence. With his valuable idea of evolution
Aristotle combined another very curious, and no doubt, absurd, theory.
This was that in the scale of the universe the lowest existence is to
be found in the middle, the highest at the periphery, and that in
general the higher is always outside the lower, so that the spatial
universe is a system of concentric spheres, the outer sphere being
related to the inner sphere as higher to lower, as form to matter. At
the centre of the spherical universe is our earth. Earth, as the
lowest element, is in the middle. Then comes a layer of water, then of
air, then of fire. Among the heavenly bodies there are fifty-six
spheres. The stars are outside the planets and are therefore higher
beings. And in conformity with this scheme, the supreme being, God, is
outside the outermost sphere. Now it is obvious that, in this scheme,
the passage from the centre of the earth to the stars forms a spatial
continuity, and it is impossible to resist the conclusion that it also
forms a logical continuity, that is, that there is no break in the
chain of evolution.
Noting that this is not what Aristotle in so many words says, but that
it is our interpretation of his {306} intention, which is almost
certainly correct, we conclude that man is not the top of the scale.
Next to him come the heavenly bodies. The planets include the sun and
the moon, which, revolve round the earth in a direction opposite to
that of the stars. Next in the scale come the stars. We need not go
into details of the fifty-six spheres. The stars and planets are
divine beings. But this is only a comparative term. Man, as the
possessor of reason, is also divine, but the heavenly bodies
infinitely more so. And this means that they are more rational than
man, and so higher in the scale. They live an absolutely blessed and
perfect life. They are immortal and eternal, because they are the
supreme self-realization of the eternal reason. It is only upon this
earth that death and corruption occur, a circumstance which has no
doubt emphasized that view of Aristotle's philosophy which holds the
gap between man and the stars to be a real one. The heavenly bodies
are not composed of the four elements, but of a fifth, a quintessence,
which is called ether. Like all elements it must have its natural
motion. And as it is the finest and most perfect, its motion must be
perfect. And it must be an eternal motion, because the stars are
eternal beings. It cannot be motion in a straight line, because that
never comes to an end, and so is never perfect. Circular motion alone
is perfect. And it is eternal because its end and its beginning are
one. Hence the natural motion of ether is circular, and the stars move
in perfect circles.
Leaving the stars behind, we reach the summit of the long ladder from
matter to form. This is the absolute form, God. As formless matter is
not an existent thing, nor is matterless form. God, therefore, is not
in the {307} world of space and time at all. But it is one of the
curiosities of thought that Aristotle nevertheless gives him a place
outside the outermost sphere. What is outside the sphere is,
therefore, not space. All space and time are inside this globular
universe. Space is therefore finite. And God must be outside the
outermost sphere because he is the highest being, and the higher
always comes outside the lower.
We have now described the entire scale of evolution. Looking back upon
it, we can see its inner significance. The Absolute is reason,
matterless form. Everything in the world, therefore, is, in its
essence, reason. If we wish to know the essential nature even of this
clod of earth, the answer is that it is reason, although this view is
not consistently developed by Aristotle, since he allows that matter
is a separate principle which cannot be reduced to form. The whole
universal process of things is nothing but the struggle of reason to
express itself, to actualize itself, to become existent in the world.
This it definitely does, for the first time proximately in man, and
completely in the stars. It can only express itself in lower beings as
sensation (animals), as nutrition (plants), or as gravitation and its
opposite (inorganic matter).
The value of Aristotle's theory of evolution is immense. It is not the
details that signify. The application of the principle in the world of
matter and life could not be carried out satisfactorily in the then
state of physical science. It could not be carried out with perfection
even now. Omniscience alone could give finality to such a scheme. But
it is the principle itself which matters. And that it is one of the
most valuable conceptions in {308} philosophy will perhaps be more
evident if we compare it, firstly, with modern scientific theories of
evolution and secondly, with certain aspects of Hindu pantheism.
What has Aristotle in common with such a writer a Herbert Spencer?
According to Spencer, evolution is a movement from the indefinite,
incoherent, and homogeneous, to the definite, coherent, and
heterogeneous. Aristotle has all this, though his words are different.
He calls it a movement from matter to form. Form he describes as
whatever gives definiteness to a thing. Matter is the indefinite
substrate, form gives it definiteness. Hence for him too the higher
being is more definite because it has more form. That matter is the
homogeneous, form the heterogeneous, follows from this. We saw that
there are in matter itself no differences, because there are no
qualities. And this is the same as saying it is homogeneous.
Heterogeneity, that is, differentiation, is introduced by form.
Coherence is the same thing as organization. Aristotle has himself
defined the form of a thing as its organization. For him, as for
Spencer, the higher being is simply that which is more organized.
Every theory of evolution depends fundamentally upon the idea of
organism. Aristotle invented the idea and the word. Spencer carried it
no further, though the more advanced physical knowledge of his day
enabled him to illustrate it more copiously.
But of course the great difference between Aristotle and the moderns,
is that the former did not guess, what the latter have discovered,
namely that evolution is not only a logical development, but is a fact
in time. Aristotle knew what was meant by the higher and lower
organism as well as Darwin, but he did not know, that the latter {309}
actually turns into the former in the course of years. But this,
though the most obvious, is not really the most important difference
between Spencer and Aristotle. The real difference is that Aristotle
penetrated far more deeply into the philosophy of evolution than
modern science does; that, in fact, modern science has no philosophy
of evolution at all. For the fundamental problem here is, if we speak
of higher and lower beings, what rational ground have we for calling
them higher and lower? That the lower passes in time into the higher
is no doubt a very interesting fact to discover, but it dwindles into
insignificance beside the problem just indicated, because, on the
solution of that problem it depends whether the universe is to be
regarded as futile, meaningless, and irrational, or whether we are to
see in it order, plan, and purpose. Is Spencer's doctrine a theory of
development at all? Or is it not rather simply a theory of change?
Something resembling an ape becomes a man. Is there development here,
that is, is it a movement from something really lower to something
really higher? Or is it merely change from one indifferent thing to
another? Is there improvement, or only difference? In the latter case,
it makes not the slightest difference whether the ape becomes man, or
man becomes an ape. The one is as good as the other. In either case,
it is merely a change from Tweedledum to Tweedledee. The change is
meaningless, and has no significance.
The modern doctrine of evolution can only render the world more
intelligible, can only develop into a philosophy of evolution, by
showing that there is evolution and not merely change, and this it can
only do by {310} giving a rational basis for the belief that some
forms of existence are higher than others. To put the matter bluntly,
why is a man higher than a horse, or a horse than a sponge? Answer
that, and you have a philosophy of evolution. Fail to answer it, and
you have none. Now the man in the street will say that man is higher
than the horse, because he not merely eats grass, but thinks,
deliberates, possesses art, science, religion, morality. Ask him why
these things are higher than eating grass, and he has no answer. From
him, then, we turn to Spencer, and there we find a sort of answer. Man
is higher because he is more organized. But why is it better to be
more organized? Science, as such, has no answer. If pressed in this
way, science may of course turn round and say: "there is in the
reality of things no higher and no lower; what I mean by higher and
lower is simply more and less organized; higher and lower are mere
metaphors; they are the human way of looking at things; we naturally
call higher what is nearest ourselves; but from the absolute point of
view there is no higher and lower." But this is to reduce the universe
to a madhouse. It means that there is no purpose, no reason, in
anything that happens. The universe, in this case, is irrational. No
explanation of it is possible. Philosophy is futile, and not only
philosophy, but morality and everything else. If there is really no
higher and lower, there is no better and no worse. It is just as good
to be a murderer as to be a saint. Evil is the same as good. Instead
of striving to be saints, statesmen, philosophers, we may as well go
and play marbles, because all these values of higher and lower are
mere delusions, "the human way of looking at things."
{311}
Spencer then has no answer to the question why it is better to be more
organized. So we turn at last to Aristotle. He has an answer. He sees
that it is meaningless to talk of development, advance, higher and
lower, except in relation to an end. There is no such thing as advance
unless it is an advance towards something. A body moving purposelessly
in a straight line through infinite space does not advance. It might
as well be here as a mile hence. In either case it is no nearer to
anything. But if it is moving towards a definite point, we can call
this advance. Every mile it moves it gets nearer to its end. So, if we
are to have a philosophy of evolution, it must be teleological. If
nature is not advancing towards an end, there is no nearer and
further, no higher and lower, no development. What then is the end? It
is the actualization of reason, says Aristotle. The primal being is
eternal reason, but this is not existent. It must come to exist. It
first enunciates itself vaguely as gravitation. But this is far off
from its end, which is the existence of reason, as such, in the world.
It comes nearer in plants and animals. It is proximately reached in
man, for man is the existent reason. But there is no question of the
universe coming to a stop, when it reaches its end--(the usual
objection to teleology). For the absolute end, absolute form, can
never be reached. The higher is thus the more rational, the lower the
less rational. Now if we try to go on asking, "why is it better to be
more rational?" we find we cannot ask such a question. The word "why"
means that we want a reason. And our question is absurd because we are
asking a reason for reason. Why is it better to be rational means
simply, "how is reason rational." To {312} doubt it is a
self-contradiction. Or, to put the same thing in another way, reason
is the Absolute. And to ask why it is better to be rational is to
demand that the ultimate should be expressed in terms of something
beyond it. Hence modern science has no philosophy of evolution,
whereas Aristotle has. [Footnote 16]
[Footnote 16: See H. S. Macran's _Hegel's Doctrine of Formal Logic_
(Clarendon Press), Introduction, section on the Conception of
Evolution, to which I am much indebted in the above paragraphs.]
The main idea of pantheism is that everything is God. The clod of
earth is divine because it is a manifestation of Deity. Now this idea
is all very well, and is in fact essential to philosophy. We find it
in Aristotle himself, since the entire world is, for him, the
actualization of reason, and reason is God. But this is also a very
dangerous idea, if not supplemented by a rationally grounded scale of
values. No doubt everything is, in a sense, God. But if we leave it at
this, it would follow that, since everything is equally divine, there
is no higher and lower. If the clod of earth, like the saintliest man,
is God, and there is no more to say of the matter, then how is the
saint higher than the clod of earth? Why should one ever struggle
towards higher things, when in reality all are equally high? Why avoid
evil, when evil is as much a manifestation of God as good? Mere
pantheism must necessarily end in this calamitous view. And these
deplorable effects explain the fact that Hinduism, with all its high
thinking, finds room for the worship of cows and snakes, and, with all
its undoubted moral elevation, yet allows into its fold the grossest
abominations. Both these features are due to the pantheistic placing
of all things on a par as equally {313} divine. Not of course that
Hinduism has not a sort of doctrine of evolution, a belief in a higher
and lower. As everyone knows, it admits the belief that in successive
incarnations the soul may mount higher and higher till it perhaps
rejoins the common source of all things. There is probably no race of
man so savage that it does not instinctively feel that there is a
higher and lower, a better and worse, in things. But the point is
that, although Hinduism has its scale of values, and its doctrine of
development, it has no rational foundation for these, and though it
has the idea of higher and lower, yet, because this is without
foundation, it lets it slip, it never grips the idea, and so easily
slides into the view that all is equally divine. The thought that all
is God, and the thought that there are higher and lower beings, are,
on the surface, opposed and inconsistent theories. Yet both are
necessary, and it is the business of philosophy to find a
reconciliation. This Aristotle does, but Hinduism fails to do. It
asserts both, but fails to bring them to unity. Now it asserts one
view, and again at another time it asserts the other. And this, of
course, is connected with the general defect of oriental thinking, its
vagueness. Everything is seen, but seen in a haze, in which all things
appear one, in which shapes flow into another, in which nothing has an
outline, in which even vital distinctions are obliterated. Hence it is
that, though oriental thought contains, in one way or another,
practically all philosophical ideas, it grips none, and can hold
nothing fast. It seizes its object, but its flabby grasp relaxes and
slips off. Hinduism, like modern science, has its doctrine of
evolution. But it has no philosophy of evolution.
{314}
5. Ethics.
_(a) The Individual_.
A strong note of practical moderation pervades the ethics of
Aristotle. While Plato's ethical teaching transcended the ordinary
limits of human life, and so lost itself in ideal Utopias, Aristotle,
on the other hand, sits down to make practical suggestions: He wishes
to enquire what the good is, but by this he means, not some ideal good
impossible of attainment upon this earth, but rather that good which,
in all the circumstances in which men find themselves, ought to be
realizable. The ethical theories of Plato and Aristotle are thus
characteristic of the two men. Plato despised the world of sense, and
sought to soar altogether beyond the common life of the senses.
Aristotle, with his love of facts and of the concrete, keeps close
within the bounds of actual human experience.
The first question for ethics is the nature of the _summum bonum_. We
desire one thing for the sake of a second, we desire that for the sake
of a third. But if this series of means and ends goes on _ad
infinitum_, then all desire and all action are futile and purposeless.
There must be some one thing which we desire, not for the sake of
anything else, but on its own account. What is this end in itself,
this _summum bonum_, at which all human activity ultimately aims.
Everybody, says Aristotle, is agreed about the name of this end. It is
happiness. What all men seek, what is the motive of all their actions,
that which they desire for the sake of itself and nothing beyond, is
happiness. But though all agree as to the name, beyond that there is
no agreement. Philosophers, {315} no less than the vulgar, differ as
to what this word happiness means. Some say it is a life of pleasure.
Others say it consists in the renunciation of pleasures. Some
recommend one life, some another.
We must repeat here the warning which was found necessary in the case
of Plato, who also called the _summum bonum_ happiness. Aristotle's
doctrine is no more to be confused with modern utilitarianism than is
Plato's. Moral activity is usually accompanied by a subjective feeling
of enjoyment. In modern times the word happiness connotes the feeling
of enjoyment. But for the Greeks it was the moral activity which the
word signified. For Aristotle an action is not good because it yields
enjoyment. On the contrary, it yields enjoyment because it is good.
The utilitarian doctrine is that the enjoyment is the ground of the
moral value. But, for Aristotle, the enjoyment is the consequence of
the moral value. Hence when he tells us that the highest good is
happiness, he is giving us no information regarding its nature, but
merely applying a new name to it. We have still to enquire what the
nature of the good is. As he himself says, everyone agrees upon the
name, but the real question is what this name connotes.
Aristotle's solution of this problem follows from the general
principles of his philosophy. We have seen that, throughout nature,
every being has its proper end, and the attainment of this end is its
special function. Hence the good for each being must be the adequate
performance of its special function. The good for man will not consist
in the pleasure of the senses. Sensation is the special function of
animals, but not of man. Man's special function is reason. Hence the
proper {316} activity of reason is the _summum bonum_, the good for
man. Morality consists in the life of reason. But what precisely that
means we have still to see.
Man is not only a reasoning animal. As the higher being, he contains
within himself the faculties of the lower beings also. Like plants he
is appetitive, like animals, sensitive. The passions and appetites are
an organic part of his nature. Hence virtue will be of two kinds. The
highest virtues will be found in the life of reason, and the life of
thought, philosophy. These intellectual virtues are called by
Aristotle dianoetic. Secondly, the ethical virtues proper will consist
in the submission of the passions and appetites to the control of
reason. The dianoetic virtues are the higher, because in them man's
special function alone is in operation, and also because the thinking
man most resembles God, whose life is a life of pure thought.
Happiness, therefore, consists in the combination of dianoetic and
ethical virtues. They alone are of absolute value to man. Yet, though
he places happiness in virtue, Aristotle, in his broad and practical
way, does not overlook the fact that external goods and circumstances
have a profound influence upon happiness, and cannot be ignored, as
the Cynics attempted to ignore them. Not that Aristotle regards
externals as having any value in themselves. What alone is good in
itself, is an end in itself, is virtue. But external goods help a man
in his quest of virtue. Poverty, sickness, and misfortune, on the
other hand, hinder his efforts. Therefore, though externals are not
goods in themselves, they may be a means towards the good. Hence they
are not to be despised and rejected. Riches, friends, health, {317}
good fortune, are not happiness. But they are negative conditions of
it. With them happiness is within our grasp. Without them its
attainment is difficult. They will be valued accordingly.
Aristotle says little in detail of the dianoetic virtues. And we may
turn at once to the main subject of his moral system, the ethical
virtues. These consist in the governance of the passions by reason.
Socrates was wrong in supposing that virtue is purely intellectual,
that nothing save knowledge is needed for it, and that if a man thinks
right he must needs do right. He forgot the existence of the passions,
which are not easily controlled. A man may reason perfectly, his
reason may point him to the right path, but his passions may get the
upper hand and lead him out of it. How then is reason to gain control
over the appetites? Only by practice. It is only by continual effort,
by the constant exercise of self-control, that the unruly passions can
be tamed. Once brought under the yoke, their control becomes habit.
Aristotle lays the utmost emphasis on the importance of habit in
morality. It is only by cultivating good habits that a man becomes
good.
Now if virtue consists in the control of the appetites by reason, it
thus contains two constituents, reason and appetite. Both must be
present. There must be passions, if they are to be controlled. Hence
the ascetic ideal of rooting out the passions altogether is
fundamentally wrong. It overlooks the fact that the higher form does
not exclude the lower--that were contrary to the conception of
evolution--it includes and transcends it. It forgets that the passions
are an organic part of man, and that to destroy them is to do injury
to his {318} nature by destroying one of its essential members. The
passions and appetites are, in fact, the matter of virtue, reason its
form, and the mistake of asceticism is that it destroys the matter of
virtue, and supposes that the form can subsist by itself. Virtue means
that the appetites must be brought under control, not that they must
be eradicated. Hence there are two extremes to be avoided. It is
extreme, on the one hand, to attempt to uproot the passions; and it is
extreme, on the other, to allow them to run riot. Virtue means
moderation. It consists in hitting the happy mean as regards the
passions, in not allowing them to get the upper hand of reason, and
yet in not being quite passionless and apathetic. From this follows
the famous Aristotelian doctrine of virtue as the mean between two
extremes. Every virtue lies between two vices, which are the excess
and defect of appetite respectively.
What is the criterion here? Who is to judge? How are we to know what
is the proper mean in any matter? Mathematical analogies will not help
us. It is not a case of drawing a straight line from one extreme to
the other, and finding the middle point by bisection. And Aristotle
refuses to lay down any rule of thumb in the matter. There is no
golden rule by virtue of which we can tell where the proper mean is.
It all depends on circumstances, and on the person involved. What is
the proper mean in one case is not the proper mean in another. What is
moderate for one man is immoderate for his neighbour. Hence the matter
must be left to the good judgment of the individual. A sort of fine
tact, good sense, is required to know the mean, which Aristotle calls
"insight." This insight is both the cause and the {319} effect of
virtue. It is the cause, because he who has it knows what he ought to
do. It is the effect, because it is only developed by practice. Virtue
renders virtue easy. Each time a man, by use of his insight, rightly
decides upon the mean, it becomes easier for him to discriminate next
time.
Aristotle attempts no systematic classification of the virtues, as
Plato had done. This sort of schematism is contrary to the practical
character of his thought. He sees that life is far too complex to be
treated in this way. The proper mean is different in every different
case, and therefore there are as many virtues as there are
circumstances in life. His list of virtues, therefore, is not intended
to be exhaustive. It is merely illustrative. Though the number of
virtues is infinite, there are certain well-recognized kinds of good
action, which are of such constant importance in life that they have
received names. By the example of some of these virtues Aristotle
illustrates his doctrine of the mean. For instance, courage is the
mean between cowardice and rashness. That is to say, cowardice is the
defect of boldness, rashness the excess, courage the reasonable
medium. Munificence is the mean between pettiness and vulgar
profusion, good temper between spiritlessness and irascibility,
politeness between rudeness and obsequiousness, modesty between
shamelessness and bashfulness, temperance between insensibility and
intemperance.
Justice hardly comes into the scheme; it is rather a virtue of the
State than of the individual, and it has been thought by some that the
book devoted to it in the "Ethics" has been misplaced. Justice is of
two kinds, distributive and corrective. Its fundamental idea {320} is
the assignment of advantages and disadvantages according to merit.
Distributive justice assigns honours and rewards according to the
worth of the individuals involved. Corrective justice has to do with
punishment. If a man improperly obtains an advantage, things must be
equalized by the imposition on him of a corresponding disadvantage.
Justice, however, is a general principle, and no general principle is
equal to the complexity of life. Special cases cannot be foreseen, The
necessary adjustment of human relations arising from this cause is
equity.
Aristotle is a pronounced supporter of the freedom of the will. He
censures Socrates because the latter's theory of virtue practically
amounts to a denial of freedom. According to Socrates, whoever thinks
right must necessarily do right. But this is equivalent to denying a
man's power to choose evil. And if he cannot choose evil, he cannot
choose good. For the right-thinking man does not do right voluntarily,
but necessarily. Aristotle believed, on the contrary, that man has the
choice of good and evil. The doctrine of Socrates makes all actions
involuntary. But in Aristotle's opinion only actions performed under
forcible compulsion are involuntary. Aristotle did not, however,
consider the special difficulties in the theory of free will which in
modern times have made it one of the most thorny of all philosophical
problems. Hence his treatment of the subject is not of great value to
us.
_(b) The State_.
Politics is not a separate subject from Ethics. It is merely another
division of the same subject. And {321} this, not merely because
politics is the ethics of the State as against the individual, but
because the morality of the individual really finds its end in the
State, and is impossible without it. Aristotle agrees with Plato that
the object of the State is the virtue and happiness of the citizens,
which are impossible except in the State. For man is a political
animal by nature, as is proved by his possession of speech, which
would be useless to any save a social being. And the phrase "by
nature" means the same here as elsewhere in Aristotle. It means that
the State is the end of the individual, and that activity in the State
is part of man's essential function. The State, in fact, is the form,
the individual, the matter. The State provides both an education in
virtue and the necessary opportunities for its exercise. Without it
man would not be man at all. He would be a savage animal.
The historical origin of the State Aristotle finds in the family. At
first there is the individual. The individual gets himself a mate, and
the family arises. The family, in Aristotle's opinion, includes the
slaves: for, like Plato, he sees no wrong in the institution of
slavery. A number of families, joining together, develop into a
village community, and a number of village communities into a _polis_
(city), or State. Beyond the city, of course, the Greek idea of the
State did not extend.
Such then is the historical origin of the State. But it is of capital
importance to understand that, in Aristotle's opinion, this question
of historical origin has nothing on earth to do with the far more
important question what the State essentially is. It is no mere
mechanical aggregate of families and village communities, {322} The
_nature_ of the State is not explained in this way. For though the
family is prior to the State in order of time, the State is prior to
the family and to the individual in order of thought, and in reality.
For the State is the end, and the end is always prior to that of which
it is the end. The state as form is prior to the family as matter, and
in the same way the family is prior to the individual. And as the
explanation of things is only possible by teleology, it is the end
which explains the beginning, it is the State which explains the
family, and not vice versa.
The true nature of the State, therefore, is not that it is a
mechanical sum of individuals, as a heap of sand is the sum of its
grains. The State is a real organism, and the connexion of part to
part is not mechanical, but organic. The State has a life of its own.
And its members also have their own lives, which are included in the
higher life of the State. All the parts of an organism are themselves
organisms. And as the distinction between organic and inorganic is
that the former has its end in itself, while the latter has its end
external to it, this means that the State is an end in itself, that
the individual is an end in himself, and that the former end includes
the latter. Or we may express the same thought otherwise by saying
that, in the State, both the whole and the parts are to be regarded as
real, both having their own lives and, in their character as ends,
their own rights. Consequently, there are two kinds of views of the
nature of the State, which are, according to Aristotle, fundamentally
erroneous. The first is the kind of view which depends upon asserting
the reality of the parts, but denying the reality of the whole, or,
what is the same {323} thing, allowing that the individual is an end
in himself, but denying that the State as a whole is such an end or
has a separate life of its own. The second kind of false view is of
the opposite kind, and consists in allowing reality only to the whole
State, and denying the reality of its parts, the individuals. The
opinions that the State is merely a mechanical aggregate of
individuals, that it is formed by the combination of individuals or
families for the sake of mutual protection and benefit, and that it
exists only for these purposes, are examples of the first kind. Such
views subordinate the State to the individual. The State is treated as
an external contrivance for securing the life, the property, or the
convenience of the individual. The State exists solely for the sake of
the individual, and is not in itself an end. The individual alone is
real, the State unreal, because it is only a collection of
individuals. These views forget that the State is an organism, and
they forget all that this implies. Aristotle would have condemned, on
these grounds, the social contract theory so popular in the eighteenth
century, and likewise the view of modern individualism that the State
exists solely to ensure that the liberty of the individual is
curtailed only by the right of other individuals to the same liberty.
The opposite kind of false view is illustrated by the ideal State of
Plato. As the views we have just discussed deny the reality of the
whole, Plato's view, on the contrary, denies the reality of the parts.
For him the individual is nothing, the State everything. The
individual is absolutely sacrificed to the State. He exists only _for_
the State, and thus Plato makes the mistake of setting up the State as
sole end and denying that the {324} individual is an end in himself.
Plato imagined that the State is a homogeneous unity, in which its
parts totally disappear. But the true view is that the State, as an
organism, is a unity which contains heterogeneity. It is coherent, yet
heterogeneous. And Plato makes the same mistake in his view of the
family as in his view of the individual. The family, Aristotle thinks,
is, like the individual, a real part of the social whole. It is an
organism within an organism. As such, it is an end in itself, has
absolute rights, and cannot be obliterated. But Plato expressly
proposed to abolish the family in favour of the State, and by
suggesting community of wives and the education of children in State
nurseries from the year of their birth, struck a deadly blow at an
essential part of the State organization. Aristotle thus supports the
institution of family, not on sentimental, but upon philosophic
grounds.
Aristotle gives no exhaustive classification of different kinds of
State, because forms of government may be as various as the
circumstances which give rise to them. His classification is intended
to include only outstanding types. He finds that there are six such
types, of which three are good. The other three are bad, because they
are corruptions of the good types. These are (1) Monarchy, the rule of
one man by virtue of his being so superior in wisdom to all his
fellows that he naturally rules them. The corruption of Monarchy is
(2) Tyranny, the rule of one man founded not on wisdom and capacity,
but upon force. The second good form is (3) Aristocracy, the rule of
the wiser and better few, of which the corrupt form is (4) Oligarchy,
the rule of the rich and powerful few. (5) Constitutional Republic or
Timocracy arises {325} where all the citizens are of fairly equal
capacity, i.e., where no stand-out individual or class exists, so that
all or most take a share in the government. The corresponding corrupt
form is (6) Democracy, which, though it is the rule of the many, is
more especially characterized as being the rule of the poor.
Unlike Plato, Aristotle depicts no ideal State. No single State, he
thinks, is in itself the best. Everything must depend upon the
circumstances. What is the best State in one age and county will not
be the best in another. Moreover, it is useless to discuss Utopian
constitutions. What alone interests the sane and balanced mind of
Aristotle is the kind of constitution which we may hope actually to
realize. Of the three good forms of government he considers that
monarchy is theoretically the best. The rule of a single perfectly
wise and just man would be better than any other. But it has to be
given up as impracticable, because such perfect individuals do not
exist. And it is only among primitive peoples that we find the hero,
the man whose moral stature so completely exalts him above his fellows
that he rules as a matter of course. The next best State is
aristocracy. And last, in Aristotle's opinion, comes constitutional
republic, which is, however, perhaps the State best suited to the
special needs and level of development of the Greek city-states.
6. Aesthetics, or the Theory of Art.
Plato had no systematic philosophy of Art, and his views had to be
collected from scattered references. Aristotle likewise has scarcely a
system, though his opinions are more connected, and though he devoted
a special tretise, the "Poetics", to the subject. And this {326} book,
which has come down to us in a fragmentary condition, deals exclusively
with poetry, and even in poetry only the drama is considered in detail.
What we have from Aristotle on the subject of aesthetics may be divided
roughly into two classes, firstly, reflections on the nature and
significance of art in general, and, secondly, a more detailed
application of these principles to the art of poetry. We shall deal
with these two classes of opinions in that order.
In order to know what art is, we must first know what it is not. It
must be distinguished from kindred activities. And firstly, it is
distinguished from morality in that morality is concerned with action,
art with production. Morality consists in the activity itself, art in
that which the activity produces. Hence the state of mind of the
actor, his motives, feelings, etc., are important in morality, for
they are part of the act itself. But they are not important in art,
the only essential being that the work of art should turn out well,
however it has been produced. Secondly, art is distinguished from the
activity of nature, which it in many respects resembles. Organic
beings reproduce their own kind, and, in the fact that it is concerned
with production, generation resembles art. But in generation, the
living being produces only itself. The plant produces a plant, man
begets man. But the artist produces something quite other than
himself, a poem, a picture, a statue.
Art is of two kinds, according as it aims at completing the work of
nature, or at creating something new, an imaginary world of its own
which is a copy of the real world. In the former case, we get such
arts as that of {327} medicine. Where nature has failed to produce a
healthy body, the physician helps nature out, and completes the work
that she has begun. In the latter case, we get what are, in modern
times, called the fine arts. These Aristotle calls the imitative arts.
We saw that Plato regarded all art as imitative, and that such a view
is essentially unsatisfactory. Now Aristotle uses the same word, which
he perhaps borrowed from Plato, but his meaning is not the same as
Plato's, nor does he fall into the same mistakes. That in calling art
imitative he has not in mind the thought that it has for its aim
merely the faithful copying of natural objects is proved by the fact
that he mentions music as the most imitative of the arts, whereas
music is, in fact, in this sense, the least imitative of all. The
painter may conceivably be regarded as imitating trees, rivers, or
men, but the musician for the most part produces what is unlike
anything in nature. What Aristotle means is that the artist copies,
not the sensuous object, but what Plato would call the Idea. Art is
thus not, in Plato's contemptuous phrase, a copy of a copy. It is a
copy of the original. Its object is not this or that particular thing,
but the universal which manifests itself in the particular. Art
idealizes nature, that is, sees the Idea in it. It regards the
individual thing, not as an individual, but in its universal aspects,
as the fleeting embodiment of an eternal thought. Hence it is that the
sculptor depicts not the individual man, but rather the type-man, the
perfection of his kind. Hence too, in modern times, the portrait
painter is not concerned to paint a faithful image of his model, but
takes the model merely as a suggestion, and seizes upon that essential
and eternal {328} essence, that ideal thought, or universal, which he
sees shining through the sensuous materials in which it is imprisoned.
His task is to free it from this imprisonment. The common man sees
only the particular object. The artist sees the universal in the
particular. Every individual thing is a compound of matter and form,
of particular and universal. The function of art is to exhibit the
universal in it.
Hence poetry is truer, more philosophical, than history. For history
deals only with the particular as the particular. It tells us only of
the _fact_, of what has happened. Its truth is mere correctness,
accuracy. It has not in it, as art has, the living and eternal truth.
It does not deal with the Idea. It yields us only the knowledge of
something that, having happened, having gone by, is finished. Its
object is transient and perishable. It concerns only the endless
iteration of meaningless events. But the object of art is that inner
essence of objects and events, which perishes not, and of which the
objects and events are the mere external drapery. If therefore we
would arrange philosophy, art, and history, in order of their
essential nobility and truth, we should place philosophy first,
because its object is the universal as it is in itself, the pure
universal. We should place art second, because its object is the
universal in the particular, and history last, because it deals only
with the particular as such. Yet because each thing in the world has
its own proper function, and errs if it seeks to perform the functions
of something else, hence, in Aristotle's opinion, art must not attempt
to emulate philosophy. It must not deal with the abstract universal.
The poet must not use his verses as a vehicle of abstract thought. His
proper {329} sphere is the universal as it manifests itself in the
particular, not the universal as it is in itself. Aristotle, for this
reason, censures didactic poetry. Such a poem as that of Empedocles,
who unfolded his philosophical system in metre, is not, in fact,
poetry at all. It is versified philosophy. Art is thus lower than
philosophy. The absolute reality, the inner essence of the world, is
thought, reason, the universal. To contemplate this reality is the
object alike of philosophy and of art. But art sees the Absolute not
in its final truth, but wrapped up in a sensuous drapery. Philosophy
sees the Absolute as it is in itself, in its own nature, in its full
truth; it sees it as what it essentially is, thought. Philosophy,
therefore, is the perfect truth. But this does not mean that art is to
be superseded and done away with. Because philosophy is higher than
art, it does not follow that a man should suppress the artist in
himself in order to rise to philosophy. For an essential thought of
the Aristotelian philosophy is that, in the scale of beings, even the
lower form is an end in itself, and has absolute rights. The higher
activities presuppose the lower, and rest upon them. The higher
includes the lower, and the lower, as an organic part of its being,
cannot be eradicated without injury to the whole. To suppress art in
favour of philosophy would be a mistake precisely parallel to the
moral error of asceticism. In treating of Aristotle's ethics we saw
that, although the activity of reason is held in highest esteem, the
attempt to uproot the passions was censured as erroneous. So here,
though philosophy is the crown of man's spiritual activity, art has
its rights, and is an absolute end in itself, a point which Plato
failed to see. In the human organism, the head is the {330} chief of
the members. But one does not cut off the hand because it is not the
head.
Coming now to Aristotle's special treatment of the art of poetry, we
may note that he concentrates his attention almost exclusively upon
the drama. It does not matter whether the plot of a drama is
historical or fictitious. For the object of art, the exhibition of the
universal, is just as well attained in an imaginary as in a real
series of events. Its aim is not correctness, but truth, not facts,
but the Idea. Drama is of two kinds, tragedy and comedy. Tragedy
exhibits the nobler specimens of humanity, comedy the worse. This
remark should be carefully understood. It does not mean that the hero
of a tragedy is necessarily a good man in the ordinary sense. He may
even be a wicked man. But the point is that, in some sense, he must be
a great personality. He cannot be an insignificant person. He cannot
be a nonentity. Be he good or bad, he must be conceived in the grand
manner. Milton's Satan is not good, but he is great, and would be a
fit subject for a tragedy. The soundness of Aristotle's thought here
is very noteworthy. What is mean and sordid can never form the basis
of tragedy. Modern newspapers have done their best to debauch this
word tragedy. Some wretched noteless human being is crushed to death
by a train, and the newspapers head their paragraph "Fearful Tragedy
at Peckham Rye." Now such an incident may be sad, it may be dreadful,
it may be horrible, but it is not tragic. Tragedy no doubt deals with
suffering. But there is nothing great and ennobling about this
suffering, and tragedy is concerned with the sufferings of greatness.
In the same way, Aristotle does not mean that the comic {331} hero is
necessarily a wicked man, but that he is, on the whole, a poor
creature, an insignificant being. He may be very worthy, but there is
something low and ignoble about him which makes us laugh.
Tragedy brings about a purification of the soul through pity and
terror. Mean, sordid, or dreadful things do not ennoble us. But the
representation of truly great and tragic sufferings arouses in the
beholder pity and terror which purge his spirit, and render it serene
and pure. This is the thought of a great and penetrating critic. The
theory of certain scholars, based upon etymological grounds, that it
means that the soul is purged, not _through_, but _of_ pity and
terror, that by means of a diarrhoea of these unpleasant emotions we
get rid of them and are left happy, is the thought of men whose
scholarship may be great, but whose understanding of art is limited.
Such a theory would reduce Aristotle's great and illuminating
criticism to the meaningless babble of a philistine.
7. Critical Estimate of Aristotle's Philosophy.
It is not necessary to spend so much time upon criticising Aristotle
as we spent upon doing the same for Plato, and that for two reasons.
In the first place, Plato with his obvious greatness abounded in
defects which had to be pointed out, whereas we have but little
adverse criticism for Aristotle. Secondly, Aristotle's main defect is
a dualism almost identical with that of Plato, and what has been said
of the one need only be shortly applied to the other.
At bottom Aristotle's philosophy is the same as Plato's, with some of
the main defects and crudities removed. Plato was the founder of the
philosophy of the Idea. {332} But in his hands, idealism was clogged
with unessentials, and overgrown with excrescences. His crude theory
of the soul as a thing mechanically forced in and out of the body, his
doctrines of reincarnation and recollection, the belief that this
_thing_ the soul can travel to some place far away where it will see
those _things_ the Ideas, and above all, what is the root of all
these, the confusion between reality and existence, with its
consequent degradation of the universal to a mere particular--these
were the unessentials with which Plato connected his essential
idealism. To take the pure theory of Ideas--albeit not under that
name--to purge it of these encumbrances and to cast them upon the
rubbish heap, to cleanse Plato's gold of its dross, this was the task
of Aristotle. Thought, the universal, the Idea, form--call it what
you will--this is the ultimate reality, the foundation of the world,
the absolute prius of all things. So thought both Plato and Aristotle.
But whereas Plato began to draw mental pictures of the universal, to
imagine that it existed apart in a world of its own, and so might be
experienced by the vision of the wandering soul, Aristotle saw that
this was to treat thought as if it were a thing, to turn it into a
mere particular again. He saw that the universal, though it is the
real, has no existence in a world of its own, but only in this world,
only as a formative principle of particular things. This is the
key-note of his philosophy. Aristotle registers, therefore, an
enormous advance upon Plato. His system is the perfected and completed
Greek idealism. It is the highest point reached in the philosophy of
Greece. The flower of all previous thought, the essence and pure
distillation of the Greek philosophic spirit, the gathering {333} up
of all that is good in his predecessors and the rejection of all that
is faulty and worthless--such is the philosophy of Aristotle. It was
not possible for the Greek spirit to advance further. Further
development could be only decay. And so, in fact, it turned out to be.
Aristotle deserves, too, the credit of having produced the only
philosophy of evolution which the world has ever seen, with the
exception of that of Hegel; and Hegel was enabled to found a newer
theory of evolution only by following largely in the footsteps of
Aristotle. This was perhaps Aristotle's most original contribution to
thought. Yet the factors of the problem, though not its solution, he
took from his predecessors. The problem of becoming had tortured Greek
thought from the earliest ages. The philosophy of Heracleitus, in
which it was most prominent, had failed to solve it. Heracleitus and
his successors racked their brains to discover how becoming could be
possible. But even if they had solved this minor problem, the greater
question still remained in the background, what does this becoming
mean? Becoming for them was only meaningless change. It was not
development. The world-process was an endless stream of futile and
purposeless events, "a tale, told by an idiot, full of sound and fury,
signifying nothing." Aristotle not merely asked himself how becoming
is possible. He showed that becoming has a meaning, that it signifies
something, that the world-process is a rationally ordered development
towards a rational end.
But, though Aristotle's philosophy is the highest presentation of the
truth in ancient times, it cannot be accepted as anything final and
faultless. Doubtless no philosophy can ever attain to finality. Let us
apply our {334} two-fold test. Does his principle explain the world,
and does it explain itself? First, does it explain the world? The
cause of Plato's failure here was the dualism in his system between
sense and thought, between matter and the Ideas. It was impossible to
derive the world from the Ideas, because they were absolutely
separated from the world. The gulf was so great that it could never be
bridged. Matter and Idea lay apart, and could never be brought
together. Now Aristotle saw this dualism in Plato, and attempted to
surmount it. The universal and the particular, he said, do not thus
lie apart, in different worlds. The Idea is not a thing here, and
matter a thing there, so that these two incommensurables have to be
somehow mechanically and violently forced together to form a world.
Universal and particular, matter and form, are inseparable. The
connexion between them is not mechanical, but organic. The dualism of
Plato is thus admitted and refuted. But is it really surmounted? The
answer must be in the negative. It is not enough by a _tour de force_ to
bring matter and form together, to assert that they are inseparable,
while they remain all the time, in principle, separate entities. If
the Absolute is form, matter ought to be deduced from form, shown to
be merely a projection and manifestation of it. It must be shown that
form not only moulds matter but produces it. If we assert that the one
primal reality is form, then clearly we must prove that all else in
the world, including matter, arises out of that prime being. Either
matter arises out of form or it does not. If it does, this arising
must be exhibited. If it does not, then form is not the sole ultimate
reality, for matter is equally an ultimate, underivative, {335}
primordial substance. In that case, we thus have two equally real
ultimate beings, each underived from the other, existing side by side
from all eternity. This is dualism, and this is the defect of
Aristotle. Not only does he not derive matter from form, but he
obviously sees no necessity for doing so. He would probably have
protested against any attempt to do so, for, when he identifies the
formal, final, and efficient causes with each other, leaving out the
material cause, this is equivalent to an assertion that matter cannot
be reduced to form. Thus his dualism is deliberate and persistent. The
world, says Aristotle, is composed of matter and form. Where does this
matter come from? As it does not, in his system, arise out of form, we
can only conclude that its being is wholly in itself, i.e., that it is
a substance, an absolute reality. And this is utterly inconsistent
with Aristotle's assertion that it is in itself nothing but a mere
potentiality. Thus, in the last resort, this dualism of sense and
thought, of matter and Idea, of unlimited and limiting, which runs,
"the little rift within the lute," through all Greek philosophy, is
not resolved. The world is not explained, because it is not derived
from a single principle. If form be the Absolute, the whole world must
flow out of it. In Aristotle's system, it does not.
Secondly, is the principle of form self-explanatory? Here, again, we
must answer negatively. Most of what was said of Plato under this head
applies equally to Aristotle. Plato asserted that the Absolute is
reason, and it was therefore incumbent on him to show that his account
of reason was truly rational. He failed to do so. Aristotle asserts
the same thing, for form is only {336} another word for reason. Hence
he must show us that this form is a rational principle, and this means
that he must show us that it is necessary. But he fails to do so. How
is form a necessary and self-determining principle? Why should there
be such a principle as form? We cannot see any necessity. It is a mere
fact. It is nothing but an ultimate mystery. It is so, and that is an
end of it. But why it should be so, we cannot see. Nor can we see why
there should be any of the particular kinds of form that there are. To
explain this, Aristotle ought to have shown that the forms constitute
a systematic unity, that they can be deduced one from another, just as
we saw that Plato ought to have deduced all the Ideas from one
another. Thus Aristotle asserts that the form of plants is nutrition,
of animals sensation, and that the one passes into the other. But even
if this assertion be true, it is a mere fact. He ought not merely to
have asserted this, but to have deduced sensation from nutrition.
Instead of being content to allege that, as a fact, nutrition passes
into sensation, he ought to have shown that it must pass into
sensation, that the passage from one to the other is a logical
necessity. Otherwise, we cannot see the reason why this change occurs.
That is to say, the change is not _explained_.
Consider the effects of this omission upon the theory of evolution. We
are told that the world-process moves towards an end, and that this
end is the self-realization of reason, and that it is proximately
attained in man, because man is a reasoning being. So far this is
quite intelligible. But this implies that each step in evolution is
higher than the last because it approaches nearer to {337} the end of
the world-process. And as that end is the realization of reason, this
is equivalent to saying that each step is higher than the last because
it is more rational. But how is sensation more rational than
nutrition? Why should it not be the other way about? Nutrition passes
through sensation into human reason. But why should not sensation pass
through nutrition into human reason? Why should not the order be
reversed? We cannot explain. And such an admission is absolutely fatal
to any philosophy of evolution. The whole object of such a philosophy
is to make it clear to us why the higher form is higher, and why the
lower is lower: why, for example, nutrition must, as lower, come
first, and sensation second, and not _vice versa_. If we can see no
reason why the order should not be reversed, this simply means that
our philosophy of evolution has failed in its main point. It means
that we cannot see any real difference between lower and higher, and
that therefore we have merely change without development, since it is
indifferent whether A passes into B, or B into A. The only way in
which Aristotle could have surmounted these difficulties would have
been to prove that sensation is a development of reason which goes
beyond nutrition. And he could only do this by showing that sensation
logically arises out of nutrition. For a logical development is the
same as a rational development. He ought to have logically deduced
sensation from nutrition, and so with all the other forms. As it is,
all that can be said is that Aristotle was the founder of a philosophy
of evolution because he saw that evolution implies movement towards an
end, and because he attempted to point out the different stages in the
attainment of that end, {338} but that he failed rationally to develop
the doctrine stage by stage.
As neither the principle of form in general was shown to be necessary,
nor were the particular forms deduced from each other, we have to
conclude that Aristotle like Plato, _named_ a self-explanatory
principle, reason or form, as ultimate principle of things, but failed
to show in detail that it is self-explanatory. Yet, in spite these
defects, the philosophy of Aristotle is one of the greatest
philosophies that the world has ever seen, or is ever likely to see.
If it does not solve all problems, it does render the world more
intelligible to us than it was before.
{339}
CHAPTER XIV
THE GENERAL CHARACTER OF POST-ARISTOTELIAN PHILOSOPHY
The rest of the story of Greek philosophy is soon told, for it is the
story of decay. The post-Aristotelian is the least instructive of the
three periods of Greek thought, and I shall delineate only its main
outlines.
The general characteristics of the decay of thought which set in after
Aristotle are intimately connected with the political, social, and
moral events of the time. Although the huge empire of Alexander had
broken up at the conqueror's death, this fact had in no way helped the
Greek States to throw off the yoke of their oppressors. With the
single exception of Sparta, which stubbornly held out, they had
become, for all intents and purposes, subject to the dominion of
Macedonia. And the death of Alexander did not alter this fact. It was
not merely that rude might had overwhelmed a beautiful and delicate
civilization. That civilization itself was decaying. The Greeks had
ceased to be a great and free people. Their vitality was ebbing. Had
it not been one conqueror it would have been another. They were
growing old. They had to give way before younger and sturdier races.
It was not so many years now before Greece, passing from one alien
yoke to another, was to become no more than a Roman province.
{340}
Philosophy is not something that subsists independently of the growth
and decay of the spirit of man. It goes hand in hand with political,
social, religious, and artistic development. Political organization,
art, religion, science, and philosophy, are but different forms in
which the life of a people expresses itself. The innermost substance
of the national life is found in the national philosophy, and the
history of philosophy is the kernel of the history of nations. It was
but natural, then, that from the time of Alexander onwards Greek
philosophy should exhibit symptoms of decay.
The essential mark of the decay of Greek thought was the intense
subjectivism which is a feature of all the post-Aristotelian schools.
Not one of them is interested in the solution of the world-problem for
its own sake. The pure scientific spirit, the desire for knowledge for
its own sake, is gone. That curiosity, that wonder, of which Aristotle
speaks as the inspiring spirit of philosophy, is dead. The motive
power of philosophy is no longer the disinterested pursuit of truth,
but only the desire of the individual to escape from the ills of life.
Philosophy only interests men in so far as it affects their lives. It
becomes anthropocentric and egocentric. Everything pivots on the
individual subject, his destiny, his fate, the welfare of his soul.
Religion has long since become corrupted and worthless, and philosophy
is now expected to do the work of religion, and to be a haven of
refuge from the storms of life. Hence it becomes essentially
practical. Before everything else it is ethical. All other departments
of thought are now subordinated to ethics. It is not as in the days of
the strength and youth of the Greek spirit, when Xenophanes or {341}
Anaxagoras looked out into the heavens, and naively wondered what the
sun and the stars were, and how the world arose. Men's thought no
longer turns outward toward the stars, but only inward upon
themselves. It is not the riddle of the universe, but the riddle of
human life, which makes them ponder.
This subjectivism has as its necessary consequences, one-sidedness,
absence of originality, and finally complete scepticism. Since men are
no longer interested in the wider problems of the universe, but only
in the comparatively petty problems of human life, their outlook
becomes exclusively ethical, narrow, and one-sided. He who cannot
forget his own self, cannot merge and lose himself in the universe,
but looks at all things only as they affect himself, does not give
birth to great and universal thoughts. He becomes self-centred, and
makes the universe revolve round him. Hence we no longer have now
great, universal, all-embracing systems, like those of Plato and
Aristotle. Metaphysics, physics, logic, are not studied for their own
sakes, but only as preparations for ethics. Narrowness, however, is
always compensated by intensity, which in the end becomes fanaticism.
Hence the intense earnestness and almost miraculous heights of
fanatical asceticism, to which the Stoics attained. And an unbalanced
and one-sided philosophy leads to extremes. Such a philosophy,
obsessed by a single idea, unrestrained by any consideration for other
and equally important factors of truth, regardless of all other
claims, pushes its idea pig-headedly to its logical extreme. Such a
procedure results in paradoxes and extravagances. Hence the Stoics, if
they made duty their watchword, must needs conceive it in {342} the
most extreme opposition to all natural impulses, with a sternness
unheard of in any previous ethical doctrine save that of the Cynics.
Hence the Sceptics, if they lighted on the thought that knowledge is
difficult of attainment, must needs rush to the extreme conclusion
that any knowledge is utterly impossible. Hence the Neo-Platonists
must needs cap all these tendencies by making out a drunken frenzy of
the soul to be the true organ of philosophy, and by introducing into
speculation all the fantastic paraphernalia of sorcery, demons, and
demi-gods. Absence of sanity and balance, then, are characteristics of
the last period of Greek philosophy. The serenity and calm of Plato
and Aristotle are gone, and in their place we have turgidity and
extravagance.
Lack of originality is a second consequence of the subjectivism of the
age. Since metaphysics, physics, and logic are not cultivated, except
in a purely practical interest, they do not flourish. Instead of
advancing in these arenas of thought, the philosophies of the age go
backwards. Older systems, long discredited, are revived, and their
dead bones triumphantly paraded abroad. The Stoics return to
Heracleitus for their physics, Epicurus resurrects the atomism of
Democritus. Even in ethics, on which they concentrate all their
thought, these post-Aristotelian systems have nothing essentially new
to say. Stoicism borrows its principal ideas from the Cynics,
Epicureanism from the Cyrenaics. The post-Aristotelians rearrange old
thoughts in a new order. They take up the ideas of the past and
exaggerate this or that aspect of them. They twist and turn them in
all directions, and squeeze them dry for a drop of new life. {343} But
in the end nothing new eventuates. Greek thought is finished, and
there is nothing new to be got out of it, torture it how they will.
From the first Stoic to the last Neo-Platonist, there is no
essentially new principle added to philosophy, unless we count as such
the sad and jaded ideas which the Neo-Platonists introduced from the
East.
Lastly, subjectivism ends naturally in scepticism, the denial of all
knowledge, the rejection of all philosophy. We have already seen, in
the Sophists, the phenomenon of subjectivism leading to scepticism.
The Sophists made the individual subject the measure of truth and
morals, and in the end this meant the denial of truth and morality
altogether. So it is now. The subjectivism of the Stoics and
Epicureans is followed by the scepticism of Pyrrho and his successors.
With them, as with the Sophists, nothing is true or good in itself,
but only opinion makes it so.
{344}
CHAPTER XV
THE STOICS
Zeno of Cyprus, the founder of the Stoic School, a Greek of Phoenician
descent, was born about 342 B.C., and died in 270. He is said to have
followed philosophy; because he lost all his property in a
ship-wreck--a motive characteristic of the age. He came to Athens, and
learned philosophy under Crates the Cynic, Stilpo the Megaric, and
Polemo the Academic. About 300 B.C. he founded his school at the Stoa
Poecile (many-coloured portico) whence the name Stoic. He died by his
own hand. He was followed by Cleanthes, and then by Chrysippus, as
leaders of the school. Chrysippus was a man of immense productivity
and laborious scholarship. He composed over seven hundred books, but
all are lost. Though not the founder, he was the chief pillar of
Stoicism. The school attracted many adherents, and flourished for many
centuries, not only in Greece, but later in Rome, where the most
thoughtful writers, such as Marcus Aurelius, Seneca, and Epictetus,
counted themselves among its followers.
We know little for certain as to what share particular Stoics, Zeno,
Cleanthes, or Chrysippus, had in the formation of the doctrines of the
school. But after Chrysippus the main lines of the doctrine were
complete. {345} We shall deal, therefore, with Stoicism as a whole,
and not with the special teaching of particular Stoics. The system is
divided into three parts, Logic, Physics, and Ethics, of which the
first two are entirely subservient to the last. Stoicism is
essentially a system of ethics which, however, is guided by a logic as
theory of method, and rests upon physics as foundation.
Logic.
We may pass over the formal logic of the Stoics, which is, in all
essentials, the logic of Aristotle. To this, however, they added a
theory, peculiar to themselves, of the origin of knowledge and the
criterion of truth. All knowledge, they said, enters the mind through
the senses. The mind is a _tabula rasa_, upon which sense-impressions
are inscribed. It may have a certain activity of its own, but this
activity is confined exclusively to materials supplied by the physical
organs of sense. This theory stands, of course, in sheer opposition to
the idealism of Plato, for whom the mind alone was the source of
knowledge, the senses being the sources of all illusion and error. The
Stoics denied the metaphysical reality of concepts. Concepts are
merely ideas in the mind, abstracted from particulars, and have no
reality outside consciousness.
Since all knowledge is a knowledge of sense-objects, truth is simply
the correspondence of our impressions to things. How are we to know
whether our ideas are correct copies of things? How distinguish
between reality and imagination, dreams, or illusions? What is the
criterion of truth? It cannot lie in concepts, since these are of our
own making. Nothing is true save {346} sense-impressions, and
therefore the criterion of truth must lie in sensation itself. It
cannot be in thought, but must be in feeling. Real objects, said the
Stoics, produce in us an intense feeling, or conviction, of their
reality. The strength and vividness of the image distinguish these
real perceptions from a dream or fancy. Hence the sole criterion of
truth is this striking conviction, whereby the real forces itself upon
our consciousness, and will not be denied. The relapse into complete
subjectivity will here be noted. There is no universally grounded
criterion of truth. It is based, not on reason, but on feeling. All
depends on the subjective convictions of the individual.
Physics.
The fundamental proposition of the Stoic physics is that "nothing
incorporeal exists." This materialism coheres with the sensationalism
of their doctrine of knowledge. Plato placed knowledge in thought, and
reality, therefore, in the Idea. The Stoics, however, place knowledge
in physical sensation, and reality, therefore, in what is known by the
senses, matter. All things, they said, even the soul, even God
himself, are material and nothing more than material. This belief they
based upon two main considerations. Firstly, the unity of the world
demands it. The world is one, and must issue from one principle. We
must have a monism. The idealism of Plato and Aristotle had resolved
itself into a futile struggle against the dualism of matter and
thought. Since the gulf cannot be bridged from the side of the Idea,
we must take our stand on matter, and reduce mind to it. Secondly,
body and soul, God and {347} the world, are pairs which act and react
upon one another. The body, for example, produces thoughts
(sense-impressions) in the soul, the soul produces movements in the
body. This would be impossible if both were not of the same substance.
The corporeal cannot act on the incorporeal, nor the incorporeal on
the corporeal. There is no point of contact. Hence all must be equally
corporeal.
All things being material, what is the original kind of matter, or
stuff, out of which the world is made? The Stoics turned to
Heracleitus for an answer. Fire is the primordial kind of being, and
all things are composed of fire. With this materialism the Stoics
combined pantheism. The primal fire is God. God is related to the
world exactly as the soul to the body. The human soul is likewise
fire, and comes from the divine fire. It permeates and penetrates the
entire body, and, in order that its interpenetration might be regarded
as complete, the Stoics denied the impenetrability of matter. Just as
the soul-fire permeates the whole body, so God, the primal fire,
pervades the entire world. He is the soul of the world. The world is
His body.
But in spite of this materialism, the Stoics averred that God is
absolute reason. This is not a return to idealism. It does not imply
the incorporeality of God. For reason, like all else, is material. It
means simply that the divine fire is a rational element. Since God is
reason, it follows that the world is governed by reason, and this
means two things. It means, firstly, that there is purpose in the
world, and therefore, order, harmony, beauty, and design. Secondly,
since reason is law as opposed to the lawless, it means that the
universe is {348} subject to the absolute sway of law, is governed by
the rigorous necessity of cause and effect.
Hence the individual is not free. There can be no true freedom of the
will in a world governed by necessity. We may, without harm, say that
we choose to do this or that, that our acts are voluntary. But such
phrases merely mean that we assent to what we do. What we do is none
the less governed by causes, and therefore by necessity.
The world-process is circular. God changes the fiery substance of
himself first into air, then water, then earth. So the world arises.
But it will be ended by a conflagration in which all things will
return into the primal fire. Thereafter, at a pre-ordained time, God
will again transmute himself into a world. It follows from the law of
necessity that the course taken by this second, and every subsequent,
world, will be identical in every way with the course taken by the
first world. The process goes on for ever, and nothing new ever
happens. The history of each successive world is the same as that of
all the others down to the minutest details.
The human soul is part of the divine fire, and proceeds into man from
God. Hence it is a rational soul, and this is a point of cardinal
importance in connexion with the Stoic ethics. But the soul of each
individual does not come direct from God. The divine fire was breathed
into the first man, and thereafter passes from parent to child in the
act of procreation. After death, all souls, according to some, but
only the souls of the good, according to others, continue in
individual existence until the general conflagration in which they,
and all else, return to God.
{349}
Ethics.
The Stoic ethical teaching is based upon two principles already
developed in their physics; first, that the universe is governed by
absolute law, which admits of no exceptions; and second, that the
essential nature of man is reason. Both are summed up in the famous
Stoic maxim, "Live according to nature." For this maxim has two
aspects. It means, in the first place, that men should conform
themselves to nature in the wider sense, that is, to the laws of the
universe, and secondly, that they should conform their actions to
nature in the narrower sense, to their own essential nature, reason.
These two expressions mean, for the Stoics, the same thing. For the
universe is governed not only by law, but by the law of reason, and
man in following his own rational nature is _ipso facto_ conforming
himself to the laws of the larger world. In a sense, of course, there
is no possibility of man's disobeying the laws of nature, for he, like
all else in the world, acts of necessity. And it might be asked, what
is the use of exhorting a man to obey the laws of the universe, when,
as part of the great mechanism of the world, he cannot by any
possibility do anything else? It is not to be supposed that a genuine
solution of this difficulty is to be found in Stoic philosophy. They
urged, however, that, though man will in any case do as the necessity
of the world compels him, it is given to him alone, not merely to obey
the law, but to assent to his own obedience, to follow the law
consciously and deliberately, as only a rational being can.
Virtue, then, is the life according to reason. Morality is simply
rational action. It is the universal reason which is to govern our
lives, not the caprice and self-will {350} of the individual. The wise
man consciously subordinates his life to the life of the whole
universe, and recognises himself as merely a cog in the great machine.
Now the definition of morality as the life according to reason is not
a principle peculiar to the Stoics. Both Plato and Aristotle taught
the same. In fact, as we have already seen, to found morality upon
reason, and not upon the particular foibles, feelings, or intuitions,
of the individual self, is the basis of every genuine ethic. But what
was peculiar to the Stoics was the narrow and one-sided interpretation
which they gave to this principle. Aristotle had taught that the
essential nature of man is reason, and that morality consists in
following this, his essential nature. But he recognized that the
passions and appetites have their place in the human organism. He did
not demand their suppression, but merely their control by reason. But
the Stoics looked upon the passions as essentially irrational, and
demanded their complete extirpation. They envisaged life as a battle
against the passions, in which the latter had to be completely
annihilated. Hence their ethical views end in a rigorous and
unbalanced asceticism.
Aristotle, in his broad and moderate way, though he believed virtue
alone to possess intrinsic value, yet allowed to external goods and
circumstances a place in the scheme of life. The Stoics asserted that
virtue alone is good, vice alone evil, and that all else is absolutely
indifferent. Poverty, sickness, pain, and death, are not evils.
Riches, health, pleasure, and life, are not goods. A man may commit
suicide, for in destroying his life he destroys nothing of value.
Above all, pleasure is not a good. One ought not to seek pleasure.
Virtue is {351} the only happiness. And man must be virtuous, not for
the sake of pleasure, but for the sake of duty. And since virtue alone
is good, vice alone evil, there followed the further paradox that all
virtues are equally good, and all vices equally evil. There are no
degrees.
Virtue is founded upon reason, and so upon knowledge. Hence the
importance of science, physics, logic, which are valued not for
themselves, but because they are the foundations of morality. The
prime virtue, and the root of all other virtues, is therefore wisdom.
The wise man is synonymous with the good man. From the root-virtue,
wisdom, spring the four cardinal virtues, insight, bravery,
self-control, justice. But since all virtues have one root, he who
possesses wisdom possesses all virtue, he who lacks it lacks all. A
man is either wholly virtuous, or wholly vicious. The world is divided
into wise men and fools, the former perfectly good, the latter
absolutely evil. There is nothing between the two. There is no such
thing as a gradual transition from one to the other. Conversion must
be instantaneous. The wise man is perfect, has all happiness, freedom,
riches, beauty. He alone is the perfect king, statesman, poet,
prophet, orator, critic, physician. The fool has all vice, all misery,
all ugliness, all poverty. And every man is one or the other. Asked
where such a wise man was to be found, the Stoics pointed doubtfully
at Socrates and Diogenes the Cynic. The number of the wise, they
thought, is small, and is continually growing smaller. The world,
which they painted in the blackest colours as a sea of vice and
misery, grows steadily worse.
In all this we easily recognize the features of a resuscitated
Cynicism. But the Stoics modified and softened {352} the harsh
outlines of Cynicism, and rounded off its angles. To do this meant
inconsistency. It meant that they first laid down harsh principles,
and then proceeded to tone them down, to explain them away, to admit
exceptions. Such inconsistency the Stoics accepted with their habitual
cheerfulness. This process of toning down their first harsh utterances
took place mainly in three ways. In the first place, they modified
their principle of the complete extirpation of the passions. Since
this is impossible, and, if possible, could only lead to immovable
inactivity, they admitted that the wise man might exhibit certain mild
and rational emotions, and that the roots of the passions might be
found in him, though he never allowed them to grow. In the second
place, they modified their principle that all else, save virtue and
vice, is indifferent. Such a view is unreal, and out of accord with
life. Hence the Stoics, with a masterly disregard of consistency,
stuck to the principle, and yet declared that among things indifferent
some are preferable to others. If the wise man has the choice between
health and sickness, he will choose the former. Indifferent things
were divided into three classes, those to be preferred, those to be
avoided, and those which are absolutely indifferent. In the third
place, the Stoics toned down the principle that men are either wholly
good, or wholly evil. The famous heroes and statesmen of history,
though fools, are yet polluted with the common vices of mankind less
than others. Moreover, what were the Stoics to say about themselves?
Were they wise men or fools? They hesitated to claim perfection, to
put themselves on a level with Socrates and Diogenes. Yet they could
not bring themselves to admit that there was {353} no difference
between themselves and the common herd. They were "proficients," and,
if not absolutely wise, approximated to wisdom.
If the Stoics were thus merely less consistent Cynics, and originated
nothing in the doctrines of physics and ethics so far considered, yet
of one idea at least they can claim to be the inventors. This was the
idea of cosmopolitanism. This they deduced from two grounds. Firstly,
the universe is one, proceeds from one God, is ordered by one law, and
forms one system. Secondly, however much men may differ in
unessentials, they share their essential nature, their reason, in
common. Hence all men are of one stock, as rational beings, and should
form one State. The division of mankind into warring States is
irrational and absurd. The wise man is not a citizen of this or that
State. He is a citizen of the world.
This is, however, only an application of principles already asserted.
The Stoics produced no essentially new thought, in physics, or in
ethics. Their entire stock of ideas is but a new combination of ideas
already developed by their predecessors. They were narrow, extreme,
over-rigorous, and one-sided. Their truths are all half-truths. And
they regarded philosophy too subjectively. What alone interested them
was the question, how am I to live? Yet in spite of these defects,
there is undoubtedly something grand and noble about their zeal for
duty, their exaltation above all that is petty and paltry, their
uncompromising contempt for all lower ends. Their merit, says
Schwegler, was that "in an age of ruin they held fast by the moral
idea."
{354}
CHAPTER XVI
THE EPICUREANS
Epicurus was born at Samos in 342 B.C. He founded his school a year or
two before Zeno founded the Stoa, so that the two schools from the
first ran parallel in time. The school of Epicurus lasted over six
centuries. Epicurus early became acquainted with the atomism of
Democritus, but his learning in earlier systems of philosophy does not
appear to have been extensive. He was a man of estimable life and
character. He founded his school in 306 B.C. The Epicurean philosophy
was both founded and completed by him. No subsequent Epicurean to any
appreciable extent added to or altered the doctrines laid down by the
founder.
The Epicurean system is even more purely practical in tendency than
the Stoic. In spite of the fact that Stoicism subordinates logic and
physics to ethics, yet the diligence and care which the Stoics
bestowed upon such doctrines as those of the criterion of truth, the
nature of the world, the soul, and so on, afford evidence of a
genuine, if subordinate, interest in these subjects. Epicurus likewise
divided his system into logic (which he called canonic), physics, and
ethics, yet the two former branches of thought are pursued with an
obvious carelessness and absence of interest. It is evident that
learned {355} discussions bored Epicurus. His system is amiable and
shallow. Knowledge for its own sake is not desired. Mathematics, he
said, are useless, because they have no connexion with life. The
logic, or canonic, we may pass over completely, as possessing no
elements of interest, and come at once to the physics.
Physics.
Physics interests Epicurus only from one point of view--its power to
banish superstitious fear from the minds of men. All supernatural
religion, he thought, operates for the most part upon mankind by means
of fear. Men are afraid of the gods, afraid of retribution, afraid of
death because of the stories of what comes after death. This incessant
fear and anxiety is one of the chief causes of the unhappiness of men.
Destroy it, and we have at least got rid of the prime hindrance to
human happiness. We can only do this by means of a suitable doctrine
of physics. What is necessary is to be able to regard the world as a
piece of mechanism, governed solely by natural causes, without any
interference by supernatural beings, in which man is free to find his
happiness how and when he will, without being frightened by the bogeys
of popular religion. For though the world is ruled mechanically, man,
thought Epicurus in opposition to the Stoics, possesses free will, and
the problem of philosophy is to ascertain how he can best use this
gift in a world otherwise mechanically governed. What he required,
therefore, was a purely mechanical philosophy. To invent such a
philosophy for himself was a task not suited to his indolence, and for
which he could not pretend to possess the necessary {356}
qualifications. Therefore he searched the past, and soon found what he
wanted in the atomism of Democritus. This, as an entirely mechanical
philosophy, perfectly suited his ends, and the pragmatic spirit in
which he chose his beliefs, not on any abstract grounds of their
objective truth, but on the basis of his subjective needs and personal
wishes, will be noted. It is a sign of the times. When truth comes to
be regarded as something that men may construct in accordance with
their real or imagined needs, and not in accordance with any objective
standard, we are well advanced upon the downward path of decay.
Epicurus, therefore, adopted the atomism of Democritus _en bloc_, or
with trifling modifications. All things are composed of atoms and the
void. Atoms differ only in shape and weight, not in quality. They fall
eternally through the void. By virtue of free will, they deviate
infinitesimally from the perpendicular in their fall, and so clash
against one another. This, of course, is an invention of Epicurus, and
formed no part of the doctrine of Democritus. It might be expected of
Epicurus that his modifications would not be improvements. In the
present case, the attribution of free will to the atoms adversely
affects the logical consistency of the mechanical theory. From the
collision of atoms arises a whirling movement out of which the world
emerges. Not only the world, but all individual phenomena, are to be
explained mechanically. Teleology is rigorously excluded. In any
particular case, however, Epicurus is not interested to know what
particular causes determine a phenomenon. It is enough for him to be
sure that it is wholly determined by mechanical causes, and that
supernatural agencies are excluded.
{357}
The soul being composed of atoms which are scattered at death, a
future life is not to be thought of. But this is to be regarded as the
greatest blessing. It frees us from the fear of death, and the fear of
a hereafter. Death is not an evil. For if death is, we are not; if we
are, death is not. When death comes we shall not feel it, for is it
not the end of all feeling and consciousness? And there is no reason
to fear now what we know that we shall not feel when it comes.
Having thus disposed of the fear of retribution in a future life,
Epicurus proceeds to dispose of the fear of the interference of the
gods in this life. One might have expected that Epicurus would for
this purpose have embraced atheism. But he does not deny the existence
of the gods. On the contrary, he believed that there are innumerable
gods. They have the form of men, because that is the most beautiful of
all forms. They have distinctions in sex. They eat, drink, and talk
Greek. Their bodies are composed of a substance like light. But though
Epicurus allows them to exist, he is careful to disarm them, and to
rob them of their fears. They live in the interstellar spaces, an
immortal, calm, and blessed existence. They do not intervene in the
affairs of the world, because they are perfectly happy. Why should
they burden themselves with the control of that which nowise concerns
them? Theirs is the beatitude of a wholly untroubled joy.
"Immortal are they, clothed with powers,
Not to be comforted at all,
Lords over all the fruitless hours,
Too great to appease, too high to appal,
Too far to call." [Footnote 17]
[Footnote 17: A. C. Swinburne's _Felise_.]
{358}
Man, therefore, freed from the fear of death and the fear of the gods,
has no duty save to live as happily as he can during his brief space
upon earth. We can quit the realm of physics with a light heart, and
turn to what alone truly matters, ethics, the consideration of how man
ought to conduct his life.
Ethics.
If the Stoics were the intellectual successors of the Cynics, the
Epicureans bear the same relation to the Cyrenaics. Like Aristippus,
they founded morality upon pleasure, but they differ because they
developed a purer and nobler conception of pleasure than the Cyrenaics
had known. Pleasure alone is an end in itself. It is the only good.
Pain is the only evil. Morality, therefore, is an activity which
yields pleasure. Virtue has no value on its own account, but derives
its value from the pleasure which accompanies it.
This is the only foundation which Epicurus could find, or desired to
find, for moral activity. This is his only ethical principle. The rest
of the Epicurean ethics consists in the interpretation of the idea of
pleasure. And, firstly, by pleasure Epicurus did not mean, as the
Cyrenaics did, merely the pleasure of the moment, whether physical or
mental. He meant the pleasure that endures throughout a lifetime, a
happy life. Hence we are not to allow ourselves to be enslaved by any
particular pleasure or desire. We must master our appetites. We must
often forego a pleasure if it leads in the end to greater pain. We
must be ready to undergo pain for the sake of a greater pleasure to
come.
And it was just for this reason, secondly, that the {359} Epicureans
regarded spiritual and mental pleasures as far more important than
those of the body. For the body feels pleasure and pain only while
they last. The body has in itself neither memory nor fore-knowledge.
It is the mind which remembers and foresees. And by far the most
potent pleasures and pains are those of remembrance and anticipation.
A physical pleasure is a pleasure to the body only now. But the
anticipation of a future pain is mental anxiety, the remembrance of a
past joy is a present delight. Hence what is to be aimed at above all
is a calm untroubled mind, for the pleasures of the body are
ephemeral, those of the spirit enduring. The Epicureans, like the
Stoics, preached the necessity of superiority to bodily pains and
external circumstances. So a man must not depend for his happiness
upon externals; he must have his blessedness in his own self. The wise
man can be happy even in bodily torment, for in the inner tranquillity
of his soul he possesses a happiness which far outweighs any bodily
pain. Yet innocent pleasures of sense are neither forbidden, nor to be
despised. The wise man will enjoy whatever he can without harm. Of all
mental pleasures the Epicureans laid, perhaps, most stress upon
friendship. The school was not merely a collection of
fellow-philosophers, but above all a society of friends.
Thirdly, the Epicurean ideal of pleasure tended rather towards a
negative than a positive conception of it. It was not the state of
enjoyment that they aimed at, much less the excitement of the
feelings. Not the feverish pleasures of the world constituted their
ideal. They aimed rather at a negative absence of pain, at
tranquillity, quiet calm, repose of spirit, undisturbed by fears and
{360} anxieties. As so often with men whose ideal is pleasure, their
view of the world was tinged with a gentle and even luxurious
pessimism. Positive happiness is beyond the reach of mortals. All that
man can hope for is to avoid pain, and to live in quiet contentment.
Fourthly, pleasure does not consist in the multiplication of needs and
their subsequent satisfaction. The multiplication of wants only
renders it more difficult to satisfy them. It complicates life without
adding to happiness. We should have as few needs as possible. Epicurus
himself lived a simple life, and advised his followers to do the same.
The wise man, he said, living on bread and water, could vie with Zeus
himself in happiness. Simplicity, cheerfulness, moderation,
temperance, are the best means to happiness. The majority of human
wants, and the example of the thirst for fame is quoted, are entirely
unnecessary and useless.
Lastly, the Epicurean ideal, though containing no possibility of an
exalted nobility, was yet by no means entirely selfish. A kindly,
benevolent temper appeared in these men. It is pleasanter, they said,
to do a kindness than to receive one. There is little of the stern
stuff of heroes, but there is much that is gentle and lovable, in the
amiable moralizings of these butterfly-philosophers.
{361}
CHAPTER XVII
THE SCEPTICS
Scepticism is a semi-technical term in philosophy, and means the
doctrine which doubts or denies the possibility of knowledge. It is
thus destructive of philosophy, since philosophy purports to be a form
of knowledge. Scepticism appears and reappears at intervals in the
history of thought. We have already met with it among the Sophists.
When Gorgias said that, if anything exists, it cannot be known, this
was a direct expression of the sceptical spirit. And the Protagorean
"Man is the measure of all things" amounts to the same thing, for it
implies that man can only know things as they appear to him, and not
as they are in themselves. In modern times the most noted sceptic was
David Hume, who attempted to show that the most fundamental categories
of thought, such as substance and causality, are illusory, and thereby
to undermine the fabric of knowledge. Subjectivism usually ends in
scepticism. For knowledge is the relation of subject and object, and
to lay exclusive emphasis upon one of its terms, the subject, ignoring
the object, leads to the denial of the reality of everything except
that which appears to the subject. This was so with the Sophists. And
now we have the reappearance of a similar {362} phenomenon. The
Sceptics, of whom we are about to treat, made their appearance at
about the same time as the Stoics and Epicureans. The subjective
tendencies of these latter schools find their logical conclusion in
the Sceptics. Scepticism makes its appearance usually, but not always,
when the spiritual forces of a race are in decay. When its spiritual
and intellectual impulses are spent, the spirit flags, grows weary,
loses confidence, begins to doubt its power of finding truth; and the
despair of truth is scepticism.
Pyrrho.
The first to introduce a thorough-going scepticism among the Greeks
was Pyrrho. He was born about 360 B.C., and was originally a painter.
He took part in the Indian expedition of Alexander the Great. He left
no writings, and we owe our knowledge of his thoughts chiefly to his
disciple Timon of Phlius. His philosophy, in common with all
post-Aristotelian systems, is purely practical in its outlook.
Scepticism, the denial of knowledge, is not posited on account of its
speculative interest, but only because Pyrrho sees in it the road to
happiness, and the escape from the calamities of life.
The proper course of the sage, said Pyrrho, is to ask himself three
questions. Firstly, he must ask what things are and how they are
constituted; secondly, how we are related to these things; thirdly,
what ought to be our attitude towards them. As to what things are, we
can only answer that we know nothing. We only know how things appear
to us, but of their inner substance we are ignorant. The same thing
appears differently to different people, and therefore it is {363}
impossible to know which opinion is right. The diversity of opinion
among the wise, as well as among the vulgar, proves this. To every
assertion the contradictory assertion can be opposed with equally good
grounds, and whatever my opinion, the contrary opinion is believed by
somebody else who is quite as clever and competent to judge as I am.
Opinion we may have, but certainty and knowledge are impossible. Hence
our attitude to things (the third question), ought to be complete
suspense of judgment. We can be certain of nothing, not even of the
most trivial assertions. Therefore we ought never to make any positive
statements on any subject. And the Pyrrhonists were careful to import
an element of doubt even into the most trifling assertions which they
might make in the course of their daily life. They did not say, "it is
so," but "it seems so," or "it appears so to me." Every observation
would be prefixed with a "perhaps," or "it may be."
This absence of certainty applies as much to practical as to
theoretical matters. Nothing is in itself true or false. It only
appears so. In the same way, nothing is in itself good or evil. It is
only opinion, custom, law, which makes it so. When the sage realizes
this, he will cease to prefer one course of action to another, and the
result will be apathy, _"ataraxia."_ All action is the result of
preference, and preference is the belief that one thing is better than
another. If I go to the north, it is because, for one reason or
another, I believe that it is better than going to the south. Suppress
this belief, learn that the one is not in reality better than the
other, but only appears so, and one would go in no direction at all.
Complete suppression of opinion would mean complete {364} suppression
of action, and it was at this that Pyrrho aimed. To have no opinions
was the sceptical maxim, because in practice it meant apathy, total
quietism. All action is founded on belief, and all belief is delusion,
hence the absence of all activity is the ideal of the sage. In this
apathy he will renounce all desires, for desire is the opinion that
one thing is better than another. He will live in complete repose, in
undisturbed tranquillity of soul, free from all delusions. Unhappiness
is the result of not attaining what one desires, or of losing it when
attained. The wise man, being free from desires, is free from
unhappiness. He knows that, though men struggle and fight for what
they desire, vainly supposing some things better than others, such
activity is but a futile struggle about nothing, for all things are
equally indifferent, and nothing matters. Between health and sickness,
life and death, difference there is none. Yet in so far as the sage is
compelled to act, he will follow probability, opinion, custom, and
law, but without any belief in the essential validity or truth of
these criteria.
The New Academy.
The scepticism founded by Pyrrho soon became extinct, but an
essentially similar doctrine began to be taught in the school of
Plato. After the death of Plato, the Academy continued, under various
leaders, to follow in the path marked out by the founder. But, under
the leadership of Arcesilaus, scepticism was introduced into the
school, and from that time, therefore, it is usually known as the New
Academy, for though its historical continuity as a school was not
broken, its essential character underwent change. What especially
{365} characterized the New Academy was its fierce opposition to the
Stoics, whom its members attacked as the chief dogmatists of the time.
Dogmatism, for us, usually means making assertions without proper
grounds. But since scepticism regards all assertions as equally
ill-grounded, the holding of any positive opinion whatever is by it
regarded as dogmatism. The Stoics were the most powerful, influential,
and forceful of all those who at that time held any positive
philosophical opinions. Hence they were singled out for attack by the
New Academy as the greatest of dogmatists. Arcesilaus attacked
especially their doctrine of the criterion of truth. The striking
conviction which, according to the Stoics, accompanies truth, equally
accompanies error. There is no criterion of truth, either in sense or
in reason. "I am certain of nothing," said Arcesilaus; "I am not even
certain that I am certain of nothing."
But the Academics did not draw from their scepticism, as Pyrrho had
done, the full logical conclusion as regards action. Men, they
thought, must act. And, although certainty and knowledge are
impossible, probability is a sufficient guide for action.
Carneades is usually considered the greatest of the Academic Sceptics.
Yet he added nothing essentially new to their conclusions. He appears,
however, to have been a man of singularly acute and powerful mind,
whose destructive criticism acted like a battering-ram not only upon
Stoicism, but upon all established philosophies. As examples of his
thoughts may be mentioned the two following. Firstly, nothing can ever
be proved. For the conclusion must be proved by premises, which in
turn require proof, and so _ad infinitum_. Secondly, {366} it is
impossible to know whether our ideas of an object are true, i.e.,
whether they resemble the object, because we cannot compare our idea
with the object itself. To do so would involve getting outside our own
minds. We know nothing of the object except our idea of it, and
therefore we cannot compare the original and the copy, since we can
see only the copy.
Later Scepticism.
After a period of obliteration, Scepticism again revived in the
Academy. Of this last phase of Greek scepticism, Aenesidemus, a
contemporary of Cicero, is the earliest example, and later we have the
well-known names of Simplicius and Sextus Empiricus. The distinctive
character of later scepticism is its return to the position of Pyrrho.
The New Academy, in its eagerness to overthrow the Stoic dogmatism,
had fallen into a dogmatism of its own. If the Stoics dogmatically
asserted, the Academics equally dogmatically denied. But wisdom lies
neither in assertion nor denial, but in doubt. Hence the later
Sceptics returned to the attitude of complete suspense of judgment.
Moreover, the Academics had allowed the possibility of probable
knowledge. And even this is now regarded as dogmatism. Aenesidemus was
the author of the ten well-known arguments to show the impossibility
of knowledge. They contain in reality, not ten, but only two or three
distinct ideas, several being merely different expressions of the same
line of reasoning. They are as follows. (1) The feelings and
perceptions of all living beings differ. (2) Men have physical and
mental differences, which make things appear different to them. (3)
The different senses give different {367} impressions of things. (4)
Our perceptions depend on our physical and intellectual conditions at
the time of perception. (5) Things appear different in different
positions, and at different distances. (6) Perception is never direct,
but always through a medium. For example, we see things through the
air. (7) Things appear different according to variations in their
quantity, colour, motion, and temperature. (8) A thing impresses us
differently when it is familiar and when it is unfamiliar. (9) All
supposed knowledge is predication. All predicates give us only the
relation of things to other things or to ourselves; they never tell us
what the thing in itself is. (10) The opinions and customs of men are
different in different countries.
{368}
CHAPTER XVIII
TRANSITION TO NEO-PLATONISM
It has been doubted whether Neo-Platonism ought to be included in
Greek philosophy at all, and Erdmann, in his "History of Philosophy,"
places it in the medieval division. For, firstly, an interval of no
less than five centuries separates the foundation of Neo-Platonism
from the foundation of the preceding Greek schools, the Stoic, the
Epicurean, and the Sceptic. How long a period this is will be seen if
we remember that the entire development of Greek thought from Thales
to the Sceptics occupied only about three centuries. Plotinus, the
real founder of Neo-Platonism, was born in 205 A.D., so that it is, as
far as historical time is concerned, a product of the Christian era.
Secondly, its character is largely un-Greek and un-European. The Greek
elements are largely swamped by oriental mysticism. Its seat was not
in Greece, but at Alexandria, which was not a Greek, but a
cosmopolitan, city. Men of all races met here, and, in particular, it
was here that East and West joined hands, and the fusion of thought
which resulted was Neo-Platonism. But, on the other hand, it seems
wrong to include the thought of Plotinus and his successors in
medieval philosophy. The whole character of what is usually called
medieval philosophy was determined by its growth upon a distinctively
Christian soil. It was {369} Christian philosophy. It was the product
of the new era which Christianity had substituted for paganism.
Neo-Platonism, on the other hand, is not only unchristian, but even
anti-christian. The only Christian influence to be detected in it is
that of opposition. It is a survival of the pagan spirit in Christian
times. In it the old pagan spirit struggles desperately against its
younger antagonist, and finally succumbs. In it we see the last gasp
and final expiry of the ancient culture of the Greeks. So far as it is
not Asiatic in its elements, it draws its inspiration wholly from the
philosophies of the past, from the thought and culture of Greece. On
the whole, therefore, it is properly classified as the last school of
Greek philosophy.
The long interval of time which elapsed between the rise of the
preceding Greek schools, whose history we have traced, and the
foundation of Neo-Platonism, was filled up by the continued existence,
in more or less fossilized form, of the main Greek schools, the
Academic, the Peripatetic, the Stoic, and the Epicurean, scattered and
harried at times by the inroads of scepticism. It would be wearisome
to follow in detail the development in these schools, and the more or
less trifling disputes of which it consists. No new thought, no
original principle, supervened. It is sufficient to say that, as time
went on, the differences between the schools became softened, and
their agreements became more prominent. As intellectual vigour wanes,
there is always the tendency to forget differences, to rest, as the
orientals do, in the good-natured and comfortable delusion that all
religions and all philosophies really mean much the same thing. Hence
eclecticism became characteristic of the schools. {370} They did not
keep themselves distinct. We find Stoic doctrines taught by Academics,
Academic doctrines by Stoics. Only the Epicureans kept their race
pure, and stood aloof from the general eclecticism of the time.
Certain other tendencies also made their appearance. There was a
recrudescence of Pythagoreanism, with its attendant symbolism and
mysticism. There grew up a tendency to exalt the conception of God so
high above the world, to widen so greatly the gulf which divides them,
that it was felt that there could be no community between the two,
that God could not act upon matter, nor matter upon God. Such
interaction would contaminate the purity of the Absolute. Hence all
kinds of beings were invented, demons, spirits, and angels, intended
to fill up the gap, and to act as intermediaries between God and the
world.
As an example of these latter tendencies, and as precursor of
Neo-Platonism proper, Philo the Jew deserves a brief mention. He lived
at Alexandria between 30 B.C. and 50 A.D. A staunch upholder of the
religion and scriptures of the Hebrew race, he believed in the verbal
inspiration of the Old Testament. But he was learned in Greek studies,
and thought that Greek philosophy was a dimmer revelation of those
truths which were more perfectly manifested in the sacred books of his
own race. And just as Egyptian priests, out of national vanity, made
out that Greek philosophy came from Egypt, just as orientals now
pretend that it came from India, so Philo declared that the origin of
all that was great in Greek philosophy was to be found in Judea. Plato
and Aristotle, he was certain, were followers of Moses, used the Old
Testament, and gained their wisdom therefrom! {371} Philo's own ideas
were governed by the attempt to fuse Jewish theology and Greek
philosophy into a homogeneous system. It was Philo, therefore, who was
largely responsible for contaminating the pure clear air of Greek
thought with the enervating fogs of oriental mysticism.
Philo taught that God, as the absolutely infinite, must be elevated
completely above all that is finite. No name, no thought, can
correspond to the infinity of God. He is the unthinkable and the
ineffable, and His nature is beyond the reach of reason. The human
soul reaches up to God, not through thought, but by means of a
mystical inner illumination and revelation that transcends thought.
God cannot act directly upon the world, for this would involve His
defilement by matter and the limitation of His infinity. There are
therefore intermediate spiritual beings, who, as the ministers of God,
created and control the world. All these intermediaries are included
in the Logos, which is the rational thought which governs the world.
The relation of God to the Logos, and of the Logos to the world, is
one of progressive emanation. Clearly the idea of emanation is a mere
metaphor which explains nothing, and this becomes more evident when
Philo compares the emanations to rays of light issuing from an
effulgent centre and growing less and less bright as they radiate
outwards. When we hear this, we know in what direction we are moving.
This has the characteristic ring of Asiatic pseudo-philosophy. It
reminds us forcibly of the Upanishads. We are passing out of the realm
of thought, reason, and philosophy, into the dream-and-shadow-land of
oriental mysticism, where the heavy scents of beautiful poison flowers
drug the intellect and obliterate thought in a blissful and languorous
repose.
{372}
CHAPTER XIX
THE NEO-PLATONISTS
The word Neo-Platonism is a misnomer. It does not stand for a genuine
revival of Platonism. The Neo-Platonists were no doubt the offspring
of Plato, but they were the illegitimate offspring. The true greatness
of Plato lay in his rationalistic idealism; his defects were mostly
connected with his tendency to myth and mysticism. The Neo-Platonists
hailed his defects as the true and inner secret of his doctrine,
developed them out of all recognition, and combined them with the hazy
dream-philosophies of the East. The reputed founder was Ammonius
Saccas, but we may pass him over and come at once to his disciple
Plotinus, who was the first to develop Neo-Platonism into a system,
was the greatest of all its exponents, and may be regarded as its real
founder. He was born in 205 A.D. at Lycopolis in Egypt, went to Rome
in 245, founded his School there, and remained at the head of it till
his death in 270. He left extensive writings which have been
preserved.
Plato had shown that the idea of the One, exclusive of all
multiplicity, was an impossible abstraction. Even to say "the One is,"
involves the duality of the One. The Absolute Being can be no abstract
unity, but only a unity in multiplicity. Plotinus begins by ignoring
this {373} supremely important philosophical principle. He falls back
upon the lower level of oriental monism. God, he thinks, is absolutely
One. He is the unity which lies beyond all multiplicity. There is in
him no plurality, no movement, no distinction. Thought involves the
distinction between object and subject; therefore the One is above and
beyond thought. Nor is the One describable in terms of volition or
activity. For volition involves the distinction between the willer and
the willed, activity between the actor and that upon which he acts.
God, therefore, is neither thought, nor volition, nor activity. He is
beyond all thought and all being. As absolutely infinite, He is also
absolutely indeterminate. All predicates limit their subject, and
hence nothing can be predicated of the One. He is unthinkable, for all
thought limits and confines that which is thought. He is the ineffable
and inconceivable. The sole predicates which Plotinus applies to Him
are the One and the Good. He sees, however, that these predicates, as
much as any others, limit the infinite. He regards them, therefore,
not as literally expressing the nature of the infinite, but as
figuratively shadowing it forth. They are applied by analogy only. We
can, in truth, know nothing of the One, except that it _is_.
Now it is impossible to derive the world from a first principle of
this kind. As being utterly exalted above the world, God cannot enter
into the world. As absolutely infinite, He can never limit Himself to
become finite, and so give rise to the world of objects. As absolutely
One, the many can never issue out of Him. The One cannot create the
world, for creation is an activity, and the One is immutable and
excludes all {374} activity. As the infinite first principle of all
things, the One must be regarded as in some sense the source of all
being. And yet how it can give rise to being is inconceivable, since
any such act destroys its unity and infinity. We saw once for all, in
the case of the Eleatics, that it is fatal to define the Absolute as
unity exclusive of all multiplicity, as immutable essence exclusive of
all process, and that if we do so we cut off all hope of showing how
the world has issued from the Absolute. It is just the same with
Plotinus. There is in his system the absolute contradiction that the
One is regarded, on the one hand, as source of the world, and on the
other as so exalted above the world that all relationship to the world
is impossible. We come, therefore, to a complete deadlock at this
point. We can get no further. We can find no way to pass from God to
the world. We are involved in a hopeless, logical contradiction. But
Plotinus was a mystic, and logical absurdities do not trouble mystics.
Being unable to explain how the world can possibly arise out of the
vacuum of the One, he has recourse, in the oriental style, to poetry
and metaphors. God, by reason of His super-perfection, "overflows"
Himself, and this overflow becomes the world. He "sends forth a beam"
from Himself. As flame emits light, as snow cold, so do all lower
beings issue from the One. Thus, without solving the difficulty,
Plotinus deftly smothers it in flowery phrases, and quietly passes on
his way.
The first emanation from the One is called the Nous. This Nous is
thought, mind, reason. We have seen that Plato regarded the Absolute
itself as thought. For Plotinus, however, thought is derivative. The
One is beyond thought, and thought issues forth from the One {375} as
first emanation. The Nous is not discursive thought, however. It is
not in time. It is immediate apprehension, or intuition. Its object is
twofold. Firstly, it thinks the One, though its thought thereof is
necessarily inadequate. Secondly, it thinks itself. It is the thought
of thought, like Aristotle's God. It corresponds to Plato's world of
Ideas. The Ideas of all things exist in the Nous, and not only the
Ideas of classes, but of every individual thing.
From the Nous, as second emanation, proceeds the world-soul. This is,
in Erdmann's phrase, a sort of faded-out copy of the Nous, and it is
outside time, incorporeal, and indivisible. It works rationally, but
yet is not conscious. It has a two-fold aspect, inclining upwards to
the Nous on the one hand, and downwards to the world of nature on the
other. It produces out of itself the individual souls which inhabit
the world.
The idea of emanation is essentially a poetical metaphor, and not a
rational concept. It is conceived poetically by Plotinus as resembling
light which radiates from a bright centre, and grows dimmer as it
passes outwards, till it shades off at last into total darkness. This
total darkness is matter. Matter, as negation of light, as the limit
of being, is in itself not-being. Thus the crucial difficulty of all
Greek philosophy, the problem of the whence of matter, the dualism of
matter and thought, which we have seen Plato and Aristotle struggling
in vain to subjugate, is loosely and lightly slurred over by Plotinus
with poetic metaphors and roseate phrases.
Matter Plotinus considers to be the ground of plurality and the cause
of all evil. Hence the object of life can {376} only be, as with
Plato, to escape from the material world of the senses. The first step
in this process of liberation is _"katharsis,"_ purification, the
freeing of oneself from the dominion of the body and the senses. This
includes all the ordinary ethical virtues. The second step is thought,
reason, and philosophy. In the third stage the soul rises above
thought to an intuition of the Nous. But all these are merely
preparatory for the supreme and final stage of exaltation into the
Absolute One, by means of trance, rapture, ecstasy. Here all thought
is transcended, and the soul passes into a state of unconscious swoon,
during which it is mystically united with God. It is not a thought of
God, it is not even that the soul sees God, for all such conscious
activities involve the separation of the subject from its object. In
the ecstasy all such disunion and separation are annihilated. The soul
does not look upon God from the outside. It becomes one with God. It
is God. Such mystical raptures can, in the nature of the case, only be
momentary, and the soul sinks back exhausted to the levels of ordinary
consciousness. Plotinus claimed to have been exalted in this divine
ecstasy several times during his life.
After Plotinus Neo-Platonism continues with modifications in his
successors, Porphyry, Iamblicus, Syrianus, Proclus, and others.
The essential character of Neo-Platonism comes out in its theory of
the mystical exaltation of the subject to God. It is the extremity of
subjectivism, the forcing of the individual subject to the centre of
the universe, to the position of the Absolute Being. And it follows
naturally upon the heels of Scepticism. In the Sceptics all faith in
the power of thought and reason had finally died out. They {377} took
as their watchword the utter impotence of reason to reach the truth.
From this it was but a step to the position that, if we cannot attain
truth by the natural means of thought, we will do so by a miracle. If
ordinary consciousness will not suffice, we will pass beyond ordinary
consciousness altogether. Neo-Platonism is founded upon despair, the
despair of reason. It is the last frantic struggle of the Greek spirit
to reach, by desperate means, by force, the point which it felt it had
failed to reach by reason. It seeks to take the Absolute by storm. It
feels that where sobriety has failed, the violence of spiritual
intoxication may succeed.
It was natural that philosophy should end here. For philosophy is
founded upon reason. It is the effort to comprehend, to understand, to
grasp the reality of things intellectually. Therefore it cannot admit
anything higher than reason. To exalt intuition, ecstasy, or rapture,
above thought--this is death to philosophy. Philosophy in making such
an admission, lets out its own life-blood, which is thought. In
Neo-Platonism, therefore, ancient philosophy commits suicide. This is
the end. The place of philosophy is taken henceforth by religion.
Christianity triumphs, and sweeps away all independent thought from
its path. There is no more philosophy now till a new spirit of enquiry
and wonder is breathed into man at the Renaissance and the
Reformation. Then the new era begins, and gives birth to a new
philosophic impulse, under the influence of which we are still living.
But to reach that new era of philosophy, the human spirit had first to
pass through the arid wastes of Scholasticism.

Updated editions will replace the previous one--the old editions
will be renamed.
Creating the works from public domain print editions means that no
one owns a United States copyright in these works, so the Foundation
(and you!) can copy and distribute it in the United States without
permission and without paying copyright royalties. Special rules,
set forth in the General Terms of Use part of this license, apply to
copying and distributing Project Gutenberg-tm electronic works to
protect the PROJECT GUTENBERG-tm concept and trademark. Project
Gutenberg is a registered trademark, and may not be used if you
charge for the eBooks, unless you receive specific permission. If you
do not charge anything for copies of this eBook, complying with the
rules is very easy. You may use this eBook for nearly any purpose
such as creation of derivative works, reports, performances and
research. They may be modified and printed and given away--you may do
practically ANYTHING with public domain eBooks. Redistribution is
subject to the trademark license, especially commercial
redistribution.
*** START: FULL LICENSE ***
THE FULL PROJECT GUTENBERG LICENSE
PLEASE READ THIS BEFORE YOU DISTRIBUTE OR USE THIS WORK
To protect the Project Gutenberg-tm mission of promoting the free
distribution of electronic works, by using or distributing this work
(or any other work associated in any way with the phrase "Project
Gutenberg"), you agree to comply with all the terms of the Full Project
Gutenberg-tm License (available with this file or online at
https://gutenberg.org/license).
Section 1. General Terms of Use and Redistributing Project Gutenberg-tm
electronic works
1.A. By reading or using any part of this Project Gutenberg-tm
electronic work, you indicate that you have read, understand, agree to
and accept all the terms of this license and intellectual property
(trademark/copyright) agreement. If you do not agree to abide by all
the terms of this agreement, you must cease using and return or destroy
all copies of Project Gutenberg-tm electronic works in your possession.
If you paid a fee for obtaining a copy of or access to a Project
Gutenberg-tm electronic work and you do not agree to be bound by the
terms of this agreement, you may obtain a refund from the person or
entity to whom you paid the fee as set forth in paragraph 1.E.8.
1.B. "Project Gutenberg" is a registered trademark. It may only be
used on or associated in any way with an electronic work by people who
agree to be bound by the terms of this agreement. There are a few
things that you can do with most Project Gutenberg-tm electronic works
even without complying with the full terms of this agreement. See
paragraph 1.C below. There are a lot of things you can do with Project
Gutenberg-tm electronic works if you follow the terms of this agreement
and help preserve free future access to Project Gutenberg-tm electronic
works. See paragraph 1.E below.
1.C. The Project Gutenberg Literary Archive Foundation ("the Foundation"
or PGLAF), owns a compilation copyright in the collection of Project
Gutenberg-tm electronic works. Nearly all the individual works in the
collection are in the public domain in the United States. If an
individual work is in the public domain in the United States and you are
located in the United States, we do not claim a right to prevent you from
copying, distributing, performing, displaying or creating derivative
works based on the work as long as all references to Project Gutenberg
are removed. Of course, we hope that you will support the Project
Gutenberg-tm mission of promoting free access to electronic works by
freely sharing Project Gutenberg-tm works in compliance with the terms of
this agreement for keeping the Project Gutenberg-tm name associated with
the work. You can easily comply with the terms of this agreement by
keeping this work in the same format with its attached full Project
Gutenberg-tm License when you share it without charge with others.
1.D. The copyright laws of the place where you are located also govern
what you can do with this work. Copyright laws in most countries are in
a constant state of change. If you are outside the United States, check
the laws of your country in addition to the terms of this agreement
before downloading, copying, displaying, performing, distributing or
creating derivative works based on this work or any other Project
Gutenberg-tm work. The Foundation makes no representations concerning
the copyright status of any work in any country outside the United
States.
1.E. Unless you have removed all references to Project Gutenberg:
1.E.1. The following sentence, with active links to, or other immediate
access to, the full Project Gutenberg-tm License must appear prominently
whenever any copy of a Project Gutenberg-tm work (any work on which the
phrase "Project Gutenberg" appears, or with which the phrase "Project
Gutenberg" is associated) is accessed, displayed, performed, viewed,
copied or distributed:
This eBook is for the use of anyone anywhere at no cost and with
almost no restrictions whatsoever. You may copy it, give it away or
re-use it under the terms of the Project Gutenberg License included
with this eBook or online at www.gutenberg.org
1.E.2. If an individual Project Gutenberg-tm electronic work is derived
from the public domain (does not contain a notice indicating that it is
posted with permission of the copyright holder), the work can be copied
and distributed to anyone in the United States without paying any fees
or charges. If you are redistributing or providing access to a work
with the phrase "Project Gutenberg" associated with or appearing on the
work, you must comply either with the requirements of paragraphs 1.E.1
through 1.E.7 or obtain permission for the use of the work and the
Project Gutenberg-tm trademark as set forth in paragraphs 1.E.8 or
1.E.9.
1.E.3. If an individual Project Gutenberg-tm electronic work is posted
with the permission of the copyright holder, your use and distribution
must comply with both paragraphs 1.E.1 through 1.E.7 and any additional
terms imposed by the copyright holder. Additional terms will be linked
to the Project Gutenberg-tm License for all works posted with the
permission of the copyright holder found at the beginning of this work.
1.E.4. Do not unlink or detach or remove the full Project Gutenberg-tm
License terms from this work, or any files containing a part of this
work or any other work associated with Project Gutenberg-tm.
1.E.5. Do not copy, display, perform, distribute or redistribute this
electronic work, or any part of this electronic work, without
prominently displaying the sentence set forth in paragraph 1.E.1 with
active links or immediate access to the full terms of the Project
Gutenberg-tm License.
1.E.6. You may convert to and distribute this work in any binary,
compressed, marked up, nonproprietary or proprietary form, including any
word processing or hypertext form. However, if you provide access to or
distribute copies of a Project Gutenberg-tm work in a format other than
"Plain Vanilla ASCII" or other format used in the official version
posted on the official Project Gutenberg-tm web site (www.gutenberg.org),
you must, at no additional cost, fee or expense to the user, provide a
copy, a means of exporting a copy, or a means of obtaining a copy upon
request, of the work in its original "Plain Vanilla ASCII" or other
form. Any alternate format must include the full Project Gutenberg-tm
License as specified in paragraph 1.E.1.
1.E.7. Do not charge a fee for access to, viewing, displaying,
performing, copying or distributing any Project Gutenberg-tm works
unless you comply with paragraph 1.E.8 or 1.E.9.
1.E.8. You may charge a reasonable fee for copies of or providing
access to or distributing Project Gutenberg-tm electronic works provided
that
- You pay a royalty fee of 20% of the gross profits you derive from
the use of Project Gutenberg-tm works calculated using the method
you already use to calculate your applicable taxes. The fee is
owed to the owner of the Project Gutenberg-tm trademark, but he
has agreed to donate royalties under this paragraph to the
Project Gutenberg Literary Archive Foundation. Royalty payments
must be paid within 60 days following each date on which you
prepare (or are legally required to prepare) your periodic tax
returns. Royalty payments should be clearly marked as such and
sent to the Project Gutenberg Literary Archive Foundation at the
address specified in Section 4, "Information about donations to
the Project Gutenberg Literary Archive Foundation."
- You provide a full refund of any money paid by a user who notifies
you in writing (or by e-mail) within 30 days of receipt that s/he
does not agree to the terms of the full Project Gutenberg-tm
License. You must require such a user to return or
destroy all copies of the works possessed in a physical medium
and discontinue all use of and all access to other copies of
Project Gutenberg-tm works.
- You provide, in accordance with paragraph 1.F.3, a full refund of any
money paid for a work or a replacement copy, if a defect in the
electronic work is discovered and reported to you within 90 days
of receipt of the work.
- You comply with all other terms of this agreement for free
distribution of Project Gutenberg-tm works.
1.E.9. If you wish to charge a fee or distribute a Project Gutenberg-tm
electronic work or group of works on different terms than are set
forth in this agreement, you must obtain permission in writing from
both the Project Gutenberg Literary Archive Foundation and Michael
Hart, the owner of the Project Gutenberg-tm trademark. Contact the
Foundation as set forth in Section 3 below.
1.F.
1.F.1. Project Gutenberg volunteers and employees expend considerable
effort to identify, do copyright research on, transcribe and proofread
public domain works in creating the Project Gutenberg-tm
collection. Despite these efforts, Project Gutenberg-tm electronic
works, and the medium on which they may be stored, may contain
"Defects," such as, but not limited to, incomplete, inaccurate or
corrupt data, transcription errors, a copyright or other intellectual
property infringement, a defective or damaged disk or other medium, a
computer virus, or computer codes that damage or cannot be read by
your equipment.
1.F.2. LIMITED WARRANTY, DISCLAIMER OF DAMAGES - Except for the "Right
of Replacement or Refund" described in paragraph 1.F.3, the Project
Gutenberg Literary Archive Foundation, the owner of the Project
Gutenberg-tm trademark, and any other party distributing a Project
Gutenberg-tm electronic work under this agreement, disclaim all
liability to you for damages, costs and expenses, including legal
fees. YOU AGREE THAT YOU HAVE NO REMEDIES FOR NEGLIGENCE, STRICT
LIABILITY, BREACH OF WARRANTY OR BREACH OF CONTRACT EXCEPT THOSE
PROVIDED IN PARAGRAPH 1.F.3. YOU AGREE THAT THE FOUNDATION, THE
TRADEMARK OWNER, AND ANY DISTRIBUTOR UNDER THIS AGREEMENT WILL NOT BE
LIABLE TO YOU FOR ACTUAL, DIRECT, INDIRECT, CONSEQUENTIAL, PUNITIVE OR
INCIDENTAL DAMAGES EVEN IF YOU GIVE NOTICE OF THE POSSIBILITY OF SUCH
DAMAGE.
1.F.3. LIMITED RIGHT OF REPLACEMENT OR REFUND - If you discover a
defect in this electronic work within 90 days of receiving it, you can
receive a refund of the money (if any) you paid for it by sending a
written explanation to the person you received the work from. If you
received the work on a physical medium, you must return the medium with
your written explanation. The person or entity that provided you with
the defective work may elect to provide a replacement copy in lieu of a
refund. If you received the work electronically, the person or entity
providing it to you may choose to give you a second opportunity to
receive the work electronically in lieu of a refund. If the second copy
is also defective, you may demand a refund in writing without further
opportunities to fix the problem.
1.F.4. Except for the limited right of replacement or refund set forth
in paragraph 1.F.3, this work is provided to you 'AS-IS' WITH NO OTHER
WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO
WARRANTIES OF MERCHANTIBILITY OR FITNESS FOR ANY PURPOSE.
1.F.5. Some states do not allow disclaimers of certain implied
warranties or the exclusion or limitation of certain types of damages.
If any disclaimer or limitation set forth in this agreement violates the
law of the state applicable to this agreement, the agreement shall be
interpreted to make the maximum disclaimer or limitation permitted by
the applicable state law. The invalidity or unenforceability of any
provision of this agreement shall not void the remaining provisions.
1.F.6. INDEMNITY - You agree to indemnify and hold the Foundation, the
trademark owner, any agent or employee of the Foundation, anyone
providing copies of Project Gutenberg-tm electronic works in accordance
with this agreement, and any volunteers associated with the production,
promotion and distribution of Project Gutenberg-tm electronic works,
harmless from all liability, costs and expenses, including legal fees,
that arise directly or indirectly from any of the following which you do
or cause to occur: (a) distribution of this or any Project Gutenberg-tm
work, (b) alteration, modification, or additions or deletions to any
Project Gutenberg-tm work, and (c) any Defect you cause.
Section 2. Information about the Mission of Project Gutenberg-tm
Project Gutenberg-tm is synonymous with the free distribution of
electronic works in formats readable by the widest variety of computers
including obsolete, old, middle-aged and new computers. It exists
because of the efforts of hundreds of volunteers and donations from
people in all walks of life.
Volunteers and financial support to provide volunteers with the
assistance they need are critical to reaching Project Gutenberg-tm's
goals and ensuring that the Project Gutenberg-tm collection will
remain freely available for generations to come. In 2001, the Project
Gutenberg Literary Archive Foundation was created to provide a secure
and permanent future for Project Gutenberg-tm and future generations.
To learn more about the Project Gutenberg Literary Archive Foundation

Section 4. Information about Donations to the Project Gutenberg
Literary Archive Foundation
Project Gutenberg-tm depends upon and cannot survive without wide
spread public support and donations to carry out its mission of
increasing the number of public domain and licensed works that can be
freely distributed in machine readable form accessible by the widest
array of equipment including outdated equipment. Many small donations
($1 to $5,000) are particularly important to maintaining tax exempt
status with the IRS.
The Foundation is committed to complying with the laws regulating
charities and charitable donations in all 50 states of the United
States. Compliance requirements are not uniform and it takes a
considerable effort, much paperwork and many fees to meet and keep up
with these requirements. We do not solicit donations in locations
where we have not received written confirmation of compliance. To
SEND DONATIONS or determine the status of compliance for any
particular state visit https://pglaf.org
While we cannot and do not solicit contributions from states where we
have not met the solicitation requirements, we know of no prohibition
against accepting unsolicited donations from donors in such states who
approach us with offers to donate.
International donations are gratefully accepted, but we cannot make
any statements concerning tax treatment of donations received from
outside the United States. U.S. laws alone swamp our small staff.
Please check the Project Gutenberg Web pages for current donation
methods and addresses. Donations are accepted in a number of other
ways including including checks, online payments and credit card
donations. To donate, please visit: https://pglaf.org/donate
Section 5. General Information About Project Gutenberg-tm electronic
works.
Professor Michael S. Hart was the originator of the Project Gutenberg-tm
concept of a library of electronic works that could be freely shared
with anyone. For thirty years, he produced and distributed Project
Gutenberg-tm eBooks with only a loose network of volunteer support.
Project Gutenberg-tm eBooks are often created from several printed
editions, all of which are confirmed as Public Domain in the U.S.
unless a copyright notice is included. Thus, we do not necessarily
keep eBooks in compliance with any particular paper edition.
Most people start at our Web site which has the main PG search facility:
https://www.gutenberg.org
This Web site includes information about Project Gutenberg-tm,
including how to make donations to the Project Gutenberg Literary
Archive Foundation, how to help produce our new eBooks, and how to
subscribe to our email newsletter to hear about new eBooks.
