No More Learning

The allusions to the tenets of the school in Plato and [223]
others are only fragmentary. We gather, however, from them that
Euclides was wholly antithetical to the personal turn given to
philosophy, both by the Cyrenaics and the Cynics. He revived and
developed with much dialectical subtlety the metaphysical system of
Parmenides and the Eleatics, maintaining that there is but one absolute
existence, and that sense and sense-perceptions as against this [224]
are nothing. This one absolute existence was alone absolutely good,
and the good for man could only be found in such an absorption of
himself in this one absolute good through reason and contemplation, as
would bring his spirit into perfectness of union with it. Such
absorption raised a man above the troubles and pains of life, and thus,
in insensibility to these through reason, man attained his highest good.

The school is perhaps interesting only in so far as it marks the
continued survival of the abstract dialectic method of earlier
philosophy. As such it had a very definite influence, sometimes
through agreement, sometimes by controversy, on the systems of Plato
and Aristotle now to be dealt with.

CHAPTER XIV

PLATO

_Student and wanderer--The Dialogues--Immortal longings--Art is
love--Knowledge through remembrance--Platonic love_


[239]

This great master, the Shakespeare of Greek philosophy, as one may call
him, for his fertility, his variety, his humour, his imagination, his
poetic grace, was born at Athens in the year 429 B. C. He was of noble
family, numbering among his ancestors no less a man than the great
lawgiver Solon, and tracing back his descent even further to the [240]
legendary Codrus, last king of Athens. At a very early age he seems to
have begun to study the philosophers, Heraclitus more particularly, and
before he was twenty he had written a tragedy. About that time,
however, he met Socrates; and at once giving up all thought of poetic
fame he burnt his poem, and devoted himself to the hearing of Socrates.
For ten years he was his constant companion. When Socrates met his
death in 399, Plato and other followers of the master fled at first to
Megara, as already mentioned (above, p. 132); he then entered on a
period of extended travel, first to Cyrene and {135} Egypt, thence to
Italy and Sicily. In Italy he devoted himself specially to a study of
the doctrine of Pythagoras. It is said that at Syracuse he offended
the tyrant Dionysius the elder by his freedom of speech, and was
delivered up to the Spartans, who were then at war with Athens. [241]
Ultimately he was ransomed, and found his way back to Athens, but he is
said to have paid a second visit to Sicily when the younger Dionysius
became tyrant. He seems to have entertained the hope that he might so
influence this young man as to be able to realise through him the dream
of his life, a government in accordance with the dictates of [242]
philosophy. His dream, however, was disappointed of fruition, and he
returned to Athens, there in the 'groves of Academus' a mythic hero of
Athens, to spend the rest of his days in converse with his followers,
and there at the ripe age of eighty-one he died. From the scene of his
labours his philosophy has ever since been known as the Academic [243]
philosophy. Unlike Socrates, he was not content to leave only a memory
of himself and his conversations. He was unwearied in the redaction
and correction of his written dialogues, altering them here and there
both in expression and in structure. It is impossible, therefore, to
be absolutely certain as to the historical order of composition or
publication among his numerous {136} dialogues, but a certain
approximate order may be fixed.

We may take first a certain number of comparatively short dialogues,
which are strongly Socratic in the following respects: _first_, they
each seek a definition of some particular virtue or quality; _second_,
each suggests some relation between it and knowledge; _third_, each
leaves the answer somewhat open, treating the matter suggestively
rather than dogmatically. These dialogues are _Charmides_, which
treats of Temperance (_mens sana in corpore sano_); _Lysis_, which
treats of Friendship; _Laches_, Of Courage; _Ion_, Of Poetic
Inspiration; _Meno_, Of the teachableness of Virtue; _Euthyphro_, Of
Piety.

The last of these may be regarded as marking a transition to a second
series, which are concerned with the trial and death of Socrates. The
_Euthyphro_ opens with an allusion by Socrates to his approaching
trial, and in the _Apology_ we have a Platonic version of Socrates'
speech in his own defence; in _Crito_ we have the story of his noble
self-abnegation and civic obedience after his condemnation; in _Phaedo_
we have his last conversation with his friends on the subject of
Immortality, and the story of his death.

Another series of the dialogues may be formed of those, more or less
satirical, in which the ideas and methods of the Sophists are
criticised: _Protagoras_, {137} in which Socrates suggests that all
virtues are essentially one; _Euthydemus_, in which the assumption and
'airs' of some of the Sophists are made fun of; _Cratylus_, Of the
sophistic use of words; _Gorgias_, Of the True and the False, the truly
Good and the truly Evil; _Hippias_, Of Voluntary and Involuntary Sin;
_Alcibiades_, Of Self-Knowledge; _Menexenus_, a (possibly ironical) set
oration after the manner of the Sophists, in praise of Athens.

The whole of this third series are characterised by humour, dramatic
interest, variety of personal type among the speakers, keenness rather
than depth of philosophic insight. There are many suggestions of
profounder thoughts, afterwards worked out more fully; but on the whole
these dialogues rather stimulate thought than satisfy it; the great
poet-thinker is still playing with his tools.

A higher stage is reached in the _Symposium_, which deals at once
humorously and profoundly with the subject of Love, human and divine,
and its relations to Art and Philosophy, the whole consummated in a
speech related by Socrates as having been spoken to him by Diotima, a
wise woman of Mantineia. From this speech an extract as translated by
Professor Jowett may be quoted here. It marks the transition point
from the merely playful and critical to the relatively serious and
dogmatic stage in the mind of Plato:--

{138} "Marvel not," she said, "if you believe that love is of the
immortal, as we have already several times acknowledged; for here
again, and on the same principle too, the mortal nature is seeking as
far as is possible to be everlasting and immortal: and this is only to
be attained by generation, because generation always leaves behind a
new existence in the place of the old. Nay even in the life of the
same individual there is succession and not absolute unity: a man is
called the same, and yet in the short interval which elapses between
youth and age, and in which every animal is said to have life and
identity, he is undergoing a perpetual process of loss and
reparation--hair, flesh, bones, blood, and the whole body are always
changing. Which is true not only of the body, but also of the soul,
whose habits, tempers, opinions, desires, pleasures, pains, fears,
never remain the same in any one of us, but are always coming and
going; and equally true of knowledge, which is still more
surprising--for not only do the sciences in general come and go, so
that in respect of them we are never the same; but each of them
individually experiences a like change. For what is implied in the
word 'recollection,' but the departure of knowledge, which is ever
being forgotten and is renewed and preserved by recollection, and
appears to be the same although in reality new, according to that law
of succession by which all mortal things are preserved, not absolutely
the same, but by substitution, the old worn-out mortality leaving
another new and similar existence behind--unlike the divine, which is
always the same and not another? And in this way, Socrates, the mortal
body, or mortal anything, partakes of immortality; but the immortal in
another way. Marvel not then at the love which all men have of their
offspring; for that universal love and interest is for the sake of
immortality. "

I was astonished at her words, and said: "Is this really true, O thou
wise Diotima? " And she answered with all the authority of a sophist:
"Of that, Socrates, you may be assured;--think only of the ambition of
men, and you will wonder at the senselessness of their ways, unless you
consider how they are stirred by the love of an immortality of fame.
They are ready to run risks greater far than they would have run for
their children, and to spend money and undergo any sort of {139} toil,
and even to die for the sake of leaving behind them a name which shall
be eternal. Do you imagine that Alcestis would have died to save
Admetus, or Achilles to avenge Patroclus, or your own Codrus in order
to preserve the kingdom for his sons, if they had not imagined that the
memory of their virtues, which is still retained among us, would be
immortal? Nay," she said, "I am persuaded that all men do all things,
and the better they are the more they do them, in hope of the glorious
fame of immortal virtue; for they desire the immortal.

"They whose bodies only are creative, betake themselves to women and
beget children--this is the character of their love; their offspring,
as they hope, will preserve their memory and give them the blessedness
and immortality which they desire in the future. But creative
souls--for there certainly are men who are more creative in their souls
than in their bodies--conceive that which is proper for the soul to
conceive or retain. And what are these conceptions? --wisdom and virtue
in general. And such creators are poets and all artists who are
deserving of the name inventor. But the greatest and fairest sort of
wisdom by far is that which is concerned with the ordering of states
and families, and which is called temperance and justice. And he who
in youth has the seed of these implanted in him and is himself
inspired, when he comes to maturity desires to beget and generate. He
wanders about seeking beauty that he may beget offspring--for in
deformity he will beget nothing--and naturally embraces the beautiful
rather than the deformed body; above all when he finds a fair and noble
and well-nurtured soul, he embraces the two in one person, and to such
an one he is full of speech about virtue and the nature and pursuits of
a good man; and he tries to educate him; and at the touch of the
beautiful which is ever present to his memory, even when absent, he
brings forth that which he had conceived long before, and in company
with him tends that which he brings forth; and they are married by a
far nearer tie and have a closer friendship than those who beget mortal
children, for the children who are their common offspring are fairer
and more immortal. Who, when he thinks of Homer and Hesiod and other
great poets, {140} would not rather have their children than ordinary
human ones? Who would not emulate them in the creation of children
such as theirs, which have preserved their memory and given them
everlasting glory? Or who would not have such children as Lycurgus
left behind him to be the saviours, not only of Lacedaemon, but of
Hellas, as one may say? There is Solon, too, who is the revered father
of Athenian laws; and many others there are in many other places, both
among Hellenes and barbarians. All of them have given to the world
many noble works, and have been the parents of virtue of every kind,
and many temples have been raised in their honour for the sake of their
children; which were never raised in honour of any one, for the sake of
his mortal children.

"These are the lesser mysteries of love, into which even you, Socrates,
may enter; to the greater and more hidden ones which are the crown of
these, and to which, if you pursue them in a right spirit, they will
lead, I know not whether you will be able to attain. But I will do my
utmost to inform you, and do you follow if you can. For he who would
proceed aright in this matter should begin in youth to visit beautiful
forms; and first, if he be guided by his instructor aright, to love one
such form only--out of that he should create fair thoughts; and soon he
will of himself perceive that the beauty of one form is akin to the
beauty of another; and then if beauty of form in general is his
pursuit, how foolish would he be not to recognise that the beauty in
every form is one and the same! And when he perceives this he will
abate his violent love of the one, which he will despise and deem a
small thing, and will become a lover of all beautiful forms; in the
next stage he will consider that the beauty of the mind is more
honourable than the beauty of the outward form. So that if a virtuous
soul have but a little comeliness, he will be content to love and tend
him, and will search out and bring to the birth thoughts which may
improve the young, until he is compelled to contemplate and see the
beauty of institutions and laws, and to understand that the beauty of
them all is of one family, and that personal beauty is a trifle; and
after laws and institutions he will go on to the sciences, that he may
see their beauty, being not like a servant in love with the beauty of
one youth or man or {141} institution, himself a slave mean and
narrow-minded, but drawing towards and contemplating the vast sea of
beauty, he will create many fair and noble thoughts and notions in
boundless love of wisdom; until on that shore he grows and waxes
strong, and at last the vision is revealed to him of a single science,
which is the science of beauty everywhere. To this I will proceed;
please to give me your very best attention.

"He who has been instructed thus far in the things of love, and who has
learned to see the beautiful in due order and succession, when he comes
toward the end will suddenly perceive a nature of wondrous beauty (and
this, Socrates, is the final cause of all our former toils)--a nature
which in the first place is everlasting, not growing and decaying, or
waxing and waning, in the next place not fair in one point of view and
foul in another, or at one time or in one relation or at one place
fair, at another time or in another relation or at another place foul,
as if fair to some and foul to others, or in the likeness of a face or
hands or any other part of the bodily frame, or in any form of speech
or knowledge, or existing in any other being; as for example, in an
animal, or in heaven, or in earth, or in any other place, but beauty
only, absolute, separate, simple, and everlasting, which without
diminution and without increase, or any change, is imparted to the
ever-growing and perishing beauties of all other things. He who under
the influence of true love rising upward from these begins to see that
beauty, is not far from the end. And the true order of going or being
led by another to the things of love, is to use the beauties of earth
as steps along which he mounts upwards for the sake of that other
beauty, going from one to two, and from two to all fair forms, and from
fair forms to fair practices, and from fair practices to fair notions,
until from fair notions he arrives at the notion of absolute beauty,
and at last knows what the essence of beauty is. This, my dear
Socrates," said the stranger of Mantineia, "is that life above all
others which a man should live, in the contemplation of beauty
absolute; a beauty which if you once beheld, you would see not to be
after the measure of gold, and garments, and fair boys and youths,
whose presence now entrances you; and you and many a one would be
content to live seeing only and conversing with them without meat or
drink, {142} if that were possible--you only want to be with them and
to look at them. But what if man had eyes to see the true beauty--the
divine beauty, I mean, pure and clear and unalloyed, not clogged with
the pollutions of mortality, and all the colours and vanities of human
life--thither looking, and holding converse with the true beauty divine
and simple? Do you not see that in that communion only, beholding
beauty with the eye of the mind, he will be enabled to bring forth, not
images of beauty, but realities (for he has hold not of an image but of
a reality), and bringing forth and nourishing true virtue to become the
friend of God and be immortal, if mortal man may. Would that be an
ignoble life? " (Jowett, _Plato_, vol. ii. p. 58).


Closely connected in subject with the _Symposium_ is the _Phaedrus_.
As Professor Jowett observes: "The two dialogues together contain the
whole philosophy of Plato on the nature of love, which in _The
Republic_ and in the later writings of Plato is only introduced
playfully or as a figure of speech. But in the _Phaedrus_ and
_Symposium_ love and philosophy join hands, and one is an aspect of the
other. The spiritual and emotional is elevated into the ideal, to
which in the _Symposium_ mankind are described as looking forward, and
which in the _Phaedrus_, as well as in the _Phaedo_, they are seeking
to recover from a former state of existence. "

We are here introduced to one of the most famous conceptions of Plato,
that of _Reminiscence_, or Recollection, based upon a theory of the
prior existence of the soul. In the _Meno_, already alluded to,
Socrates is representing as eliciting from one of Meno's slaves {143}
correct answers to questions involving a knowledge or apprehension of
certain axioms of the science of mathematics, which, as Socrates
learns, the slave had never been taught. Socrates argues that since he
was never taught these axioms, and yet actually knows them, he must
have known them before his birth, and concludes from this to the
immortality of the soul. In the _Phaedo_ this same argument is worked
out more fully. As we grow up we discover in the exercise of our
senses that things are equal in certain respects, unequal in many
others; or again, we appropriate to things or acts the qualities, for
example, of beauty, goodness, justice, holiness. At the same time we
recognise that these are _ideals_, to which in actual experience we
never find more than an approximation, for we never discover in any
really existing thing or act _absolute_ equality, or justice, or
goodness. In other words, any act of judgment on our part of actual
experiences consists in a measuring of these experiences by standards
which we give or apply to them, and which no number of experiences can
give to us because they do not possess or exemplify them. We did not
consciously possess these notions, or ideals, or _ideas_, as he prefers
to call them, at birth; they come into consciousness in connection with
or in consequence of the action of the senses; but since the senses
could not give these ideas, the process of {144} knowledge must be a
process of _Recollection_. Socrates carries the argument a step
further. "Then may we not say," he continues, "that if, as we are
always repeating, there is an absolute beauty and goodness and other
similar ideas or essences, and to this standard, which is now
discovered to have existed in our former state, we refer all our
sensations, and with this compare them--assuming these ideas to have a
prior existence, then our souls must have had a prior existence, but if
not, not? There is the same proof that these ideas must have existed
before we were born, as that our souls existed before we were born; and
if not the ideas, then not the souls. "

In the _Phaedrus_ this conception of a former existence is embodied in
one of the _Myths_ in which Plato's imaginative powers are seen at
their highest. In it the soul is compared to a charioteer driving two
winged steeds, one mortal, the other immortal; the one ever tending
towards the earth, the other seeking ever to soar into the sky, where
it may behold those blessed visions of loveliness and wisdom and
goodness, which are the true nurture of the soul. When the chariots of
the gods go forth in mighty and glorious procession, the soul would
fain ride forth in their train; but alas! the mortal steed is ever
hampering the immortal, and dragging it down.

If the soul yields to this influence and descends to earth, there she
takes human form, but in higher {145} or lower degree, according to the
measure of her vision of the truth. She may become a philosopher, a
king, a trader, an athlete, a prophet, a poet, a husbandman, a sophist,
a tyrant. But whatever her lot, according to her manner of life in it,
may she rise, or sink still further, even to a beast or plant.

Only those souls take the form of humanity that have had _some_ vision
of eternal truth. And this vision they retain in a measure, even when
clogged in mortal clay. And so the soul of man is ever striving and
fluttering after something beyond; and specially is she stirred to
aspiration by the sight of bodily loveliness. Then above all comes the
test of good and evil in the soul. The nature that has been corrupted
would fain rush to brutal joys; but the purer nature looks with
reverence and wonder at this beauty, for it is an adumbration of the
celestial joys which he still remembers vaguely from the heavenly
vision. And thus pure and holy love becomes an opening back to heaven;
it is a source of happiness unalloyed on earth; it guides the lovers on
upward wings back to the heaven whence they came.




{146}

CHAPTER XV

PLATO (_continued_)

_The Republic--Denizens of the cave--The Timaeus--A dream of creation_


And now we pass to the central and crowning work of Plato, _The
Republic_, or _Of Justice_--the longest with one exception, and
certainly the greatest of all his works. It combines the humour and
irony, the vivid characterisation and lively dialogue of his earlier
works, with the larger and more serious view, the more constructive and
statesmanlike aims of his later life. The dialogue opens very
beautifully. There has been a festal procession at the Piraeus, the
harbour of Athens, and Socrates with a companion is wending his way
homeward, when he is recalled by other companions, who induce him to
visit the house of an aged friend of his, Cephalus, whom he does not
visit too often. Him he finds seated in his court, crowned, as the
custom was, for the celebration of a family sacrifice, and beholds
beaming on his face the peace of a life well spent and reconciled.
They talk of the happiness that comes in old age to those who have done
good and not evil, and who are not too severely {147} tried in the
matter of worldly cares. Life to this good old man seems a very simple
matter; duty to God, duty to one's neighbours, each according to what
is prescribed and orderly; this is all, and this is sufficient.

Then comes in the questioning Socrates, with his doubts and
difficulties as to what is one's duty in special circumstances; and the
discussion is taken up, not by the good old man, "who goes away to the
sacrifice," but by his son, who can quote the authorities; and by
Thrasymachus, the Sophist, who will have nothing to do with authority,
but maintains that _interest_ is the only real meaning of justice, and
that Might is Right. Socrates, by analogy of the arts, shows that
Might absolutely without tincture of justice is mere weakness, and that
there is honour even among thieves. Yet the exhibition of the 'law
working in the members' seems to have its weak side so long as we look
to individual men, in whom there are many conflicting influences, and
many personal chances and difficulties, which obscure the relation
between just action and happiness.

Socrates therefore will have justice 'writ large' in the community as a
whole, first pictured in its simpler, and then in its more complex and
luxurious forms. The relation of the individual to the community is
represented chiefly as one of education and training; and many strange
theories--as of the equal {148} training of men and women, and the
community of wives, ideas partially drawn from Sparta--are woven into
the ideal structure. Then the dialogue rises to a larger view of
education, as a preparation of the soul of man, not for a community on
earth, but for that heavenly life which was suggested above (p. 144) in
the myth of the steeds.

The purely earthly unideal life is represented as a life of men tied
neck and heels from birth in a cave, having their backs to the light,
and their eyes fixed only on the shadows which are cast upon the wall.
These they take for the only realities, and they may acquire much skill
in interpreting the shadows. Turn these men suddenly to the true
light, and they will be dazzled and blinded. They will feel as though
they had lost the realities, and been plunged into dreams. And in pain
and sorrow they will be tempted to grope back again to the familiar
darkness.

Yet if they hold on in patience, and struggle up the steep till the sun
himself breaks on their vision, what pain and dazzling once more, yet
at the last what glorious revelation! True, if they revisit their old
dwelling-place, they will not see as well as their fellows who are
still living contentedly there, knowing nothing other than the shadows.
They may even seem to these as dreamers who have lost their senses; and
should they try to enlighten these denizens of the cave, they may be
persecuted or {149} even put to death. Such are the men who have had a
sight of the heavenly verities, when compared with the children of
earth and darkness.

Yet the world will never be right till those who have had this vision
come back to the things of earth and order them according to the
eternal verities; the philosopher must be king if ever the perfect life
is to be lived on earth, either by individual or community. As it
would be expressed in Scriptural language, "The kingdoms of this world
must become the kingdoms of the Lord and of His Christ. "

For the training of these ideal rulers an ideal education is required,
which Plato calls dialectic; something of its nature is described later
on (p. 170), and we need not linger over it here.

The argument then seems to fall to a lower level. There are various
approximations in actual experience to the ideal community, each more
or less perfect according to the degree in which the good of the
individual is also made the good of all, and the interests of governors
and governed are alike. Parallel with each lower form of state is a
lower individual nature, the worst of all being that of the tyrant,
whose will is his only law, and his own self-indulgence his only
motive. In him indeed Might is Right; but his life is the very
antithesis of happiness. Nay, pleasure of any kind can give no law to
reason; reason can judge of pleasure, but not _vice versa_. There is
no profit to a {150} man though he gain the whole world, if _himself_
be lost; if he become worse; if the better part of him be silenced and
grow weaker. And after this 'fitful fever' is over, may there not be a
greater bliss beyond? There have been stories told us, visions of
another world, where each man is rewarded according to his works. And
the book closes with a magnificent Vision of Judgment. It is the story
of Er, son of Armenius, who being wounded in battle, after twelve days'
trance comes back to life, and tells of the judgment seat, of heavenly
bliss and hellish punishments, and of the renewal of life and the new
choice given to souls not yet purified wholly of sin. "God is
blameless; Man's Soul is immortal; Justice and Truth are the only
things eternally good. " Such is the final revelation.

The _Timaeus_ is an attempt by Plato, under the guise of a Pythagorean
philosopher, to image forth as in a vision or dream the actual framing
of the universe, conceived as a realisation of the Eternal Thought or
Idea. It will be remembered that in the analysis already given (p.
143) of the process of knowledge in individual men, Plato found that
prior to the suggestions of the senses, though not coming into
consciousness except in connection with sensation, men had _ideas_ that
gave them a power of rendering their sensations intelligible. In the
_Timaeus_ Plato attempts a vision of the universe as though he saw
{151} it working itself into actuality on the lines of those ideas.
The vision is briefly as follows: There is the Eternal Creator, who
desired to make the world because He was good and free from jealousy,
and therefore willed that all things should be like Himself; that is,
that the formless, chaotic, unrealised void might receive form and
order, and become, in short, real as He was. Thus creation is the
process by which the Eternal Creator works out His own image, His own
ideas, in and through that which is formless, that which has no name,
which is nothing but possibility,--dead earth, namely, or _Matter_.
And first the world-soul, image of the divine, is formed, on which as
on a "diamond network" the manifold structure of things is
fashioned--the stars, the seven planets with their sphere-music, the
four elements, and all the various creatures, aetherial or fiery,
aerial, aqueous, and earthy, with the consummation of them all in
microcosm, in the animal world, and specially in man.

One can easily see that this is an attempt by Plato to carry out the
reverse process in thought to that which first comes to thinking man.
Man has sensations, that is, he comes first upon that which is
conceivably last in creation, on the immediate and temporary things or
momentary occurrences of earth. In these sensations, as they
accumulate into a kind of habitual or unreasoned knowledge or opinion,
he discovers elements which have been active to {152} correlate the
sensations, which have from the first exercised a governing influence
upon the sensations, without which, indeed, no two sensations could be
brought together to form anything one could name. These regulative,
underlying, permanent elements are Ideas, _i. e. _ General Forms or
Notions, which, although they may come second as regards time into
consciousness, are by reason known to have been there before, because
through them alone can the sensations become intelligibly possible, or
thinkable, or namable. Thus Plato is led to the conception of an order
the reverse of our individual experience, the order of creation, the
order of God's thought, which is equivalent to the order of God's
working; for God's thought and God's working are inseparable.

Of course Plato, in working out his dream of creation absolutely
without any scientific knowledge, the further he travels the more
obviously falls into confusion and absurdity; where he touches on some
ideas having a certain resemblance to modern scientific discoveries, as
the law of gravitation, the circulation of the blood, the quantitative
basis of differences of quality, etc. , these happy guesses are apt to
lead more frequently wrong than right, because they are not kept in
check by any experimental tests. But taken as a 'myth,' which is
perhaps all that Plato intended, the work offers much that is
profoundly interesting.

{153}

With the _Timaeus_ is associated another dialogue called the _Critias_,
which remains only as a fragment. In it is contained a description of
the celebrated visionary kingdom of Atlantis, lying far beyond the
pillars of Hercules, a land of splendour and luxury and power, a land
also of gentle manners and wise orderliness. "The fiction has
exercised a great influence over the imagination of later ages. As
many attempts have been made to find the great island as to discover
the country of the lost tribes. Without regard to the description of
Plato, and without a suspicion that the whole narrative is a
fabrication, interpreters have looked for the spot in every part of the
globe--America, Palestine, Arabia Felix, Ceylon, Sardinia, Sweden. The
story had also an effect on the early navigators of the sixteenth
century" (Jowett, _Plato_, vol. iii. p. 679).




{154}

CHAPTER XVI

PLATO (_continued_)

_Metaphysics and psychology--Reason and pleasure--Criticism of the
ideas--Last ideals_


We now come to a series of highly important dialogues, marked as a
whole by a certain diminution in the purely artistic attraction, having
less of vivid characterisation, less humour, less dramatic interest,
less perfect construction in every way, but, on the other hand,
peculiarly interesting as presenting a kind of after-criticism of his
own philosophy. In them Plato brings his philosophic conceptions into
striking relation with earlier or rival theories such as the Eleatic,
the Megarian, the Cyrenaic, and the Cynic, and touches in these
connections on many problems of deep and permanent import.

The most remarkable feature in these later dialogues is the
disappearance, or even in some cases the apparently hostile criticism,
of the doctrine of Ideas, and consequently of Reminiscence as the
source of knowledge, and even, apparently, of Personal {155}
Immortality, so far as the doctrine of Reminiscence was imagined to
guarantee it. This, however, is perhaps to push the change of view too
far. We may say that Plato in these dialogues is rather the
psychologist than the metaphysician; he is attempting a revised
analysis of mental processes. From this point of view it was quite
intelligible that he should discover difficulties in his former theory
of our mental relation to the external reality, without therefore
seeing reason to doubt the existence of that reality. The position is
somewhat similar to that of a modern philosopher who attempts to think
out the psychological problem of Human Will in relation to Almighty and
Over-ruling Providence. One may very clearly see the psychological
difficulties, without ceasing to believe either in the one or the other
as facts.

Throughout Plato's philosophy, amidst every variation of expression, we
may take these three as practically fixed points of belief or of faith,
or at least of hope; _first_, that Mind is eternally master of the
universe; _second_, that Man in realising what is most truly himself is
working in harmony with the Eternal Mind, and is in this way a master
of nature, reason governing experience and not being a product of
experience; and _thirdly_ (as Socrates said before his judges), that at
death we go to powers who are wise and good, and to men departed who in
their day shared in the divine wisdom and goodness,--that, in short,
there is something remaining for the dead, and better for those that
have done good than for those that have done evil.

The first of the 'psychological dialogues,' as we have called them, is
the _Philebus_. The question here is of the _summum bonum_ or chief
good. What is it? Is it pleasure? Is it wisdom? Or is it both? In
the process of answering these questions Plato lays down rules for true
definition, and establishes classifications which had an immense
influence on his successor Aristotle, but which need not be further
referred to here.

The general gist of the argument is as follows. Pleasure could not be
regarded as a sufficient or perfect good if it was entirely emptied of
the purely intellectual elements of anticipation and consciousness and
memory. This would be no better than the pleasure of an oyster. On
the other hand, a purely intellectual existence can hardly be regarded
as perfect and sufficient either. The perfect life must be a union of
both.

But this union must be an orderly and rational union; in other words,
it must be one in which Mind is master and Pleasure servant; the
finite, the regular, the universal must govern the indefinite,
variable, particular. Thus in the perfect life there are four
elements; in the body, earth, water, air, fire; in the soul, the
finite, the indefinite, the union of the {157} two, and the cause of
that union. If this be so, he argues, may we not by analogy argue for
a like four-fold order in the universe? There also we find regulative
elements, and indefinite elements, and the union of the two. Must
there not also be the Great Cause, even Divine Wisdom, ordering and
governing all things?

The second of the psychological series is the _Parmenides_, in which
the great Eleatic philosopher, in company with his disciple Zeno, is
imagined instructing the youthful Socrates when the two were on a visit
to Athens, which may or may not be historical (see above, p. 34). The
most striking portion of this dialogue is the criticism already alluded
to of Plato's own theory of Ideas, put into the mouth of Parmenides.
Parmenides ascertains from Socrates that he is quite clear about there
being Ideas of Justice, Beauty, Goodness, eternally existing, but how
about Ideas of such common things as hair, mud, filth, etc. ? Socrates
is not so sure; to which Parmenides rejoins that as he grows older
philosophy will take a surer hold of him, and that he will recognise
the same law in small things and in great.

But now as to the nature of these Ideas.
What, Parmenides asks, is the
relation of these, as eternally existing in the mind of God, to the
same ideas as possessed by individual men? Does each individual
actually _partake_ in the thought of God through {158} the ideas, or
are his ideas only _resemblances_ of the eternal? If he partakes, then
the eternal ideas are not one but many, as many as the persons who
possess them. If his ideas only resemble, then there must be some
basis of reference by which the resemblance is established, a _tertium
quid_ or third existence resembling both, and so _ad infinitum_.
Socrates is puzzled by this, and suggests that perhaps the Ideas are
only notions in our minds. But to this it is replied that there is an
end in that case of any reality in our ideas. Unless in some way they
have a true and causal relation with something beyond our minds, there
is an end of mind altogether, and with mind gone everything goes.

This, as Professor Jowett remarks, "remains a difficulty for us as well
as for the Greeks of the fourth century before Christ, and is the
stumbling-block of Kant's _Critic_, and of the Hamiltonian adaptation
of Kant as well as of the Platonic ideas. It has been said that 'you
cannot criticise Revelation. ' 'Then how do you know what is
Revelation, or that there is one at all? ' is the immediate rejoinder.
'You know nothing of things in themselves. '--'Then how do you know that
there are things in themselves? ' In some respects the difficulty
pressed harder upon the Greek than upon ourselves. For conceiving of
God more under the attribute of knowledge than we do, he was more under
the necessity of {159} separating the divine from the human, as two
spheres which had no communication with one another. "

Next follows an extraordinary analysis of the ideas of 'Being' and
'Unity,' remarkable not only for its subtlety, but for the relation
which it historically bears to the modern philosophic system of Hegel.
"Every affirmation is _ipso facto_ a negation;" "the negation of a
negation is an affirmation;" these are the psychological (if not
metaphysical) facts, on which the analysis of Parmenides and the
philosophy of Hegel are both founded.

We may pass more rapidly by the succeeding dialogues of the series: the
_Theaetetus_ (already quoted from above, p. 89), which is a close and
powerful investigation of the nature of knowledge on familiar Platonic
lines; the _Sophist_, which is an analysis of fallacious reasoning; and
the _Statesman_, which, under the guise of a dialectical search for the
true ruler of men, represents once more Plato's ideal of government,
and contrasts this with the ignorance and charlatanism of actual
politics.

In relation to subsequent psychology, and more particularly to the
logical system of Aristotle, these dialogues are extremely important.
We may indeed say that the systematic logic of Aristotle, as contained
in the _Organon_, is little more than an abstract {160} or digest of
the logical theses of these dialogues. Definition and division, the
nature and principle of classification, the theory of predication, the
processes of induction and deduction, the classification and criticism
of fallacies,--all these are to be found in them. The only addition
really made by Aristotle was the systematic theory of the syllogism.

The _Laws_, the longest of Plato's works, seems to have been composed
by him in the latest years of his long life, and was probably not
published till after his death. It bears traces of its later origin in
the less artful juncture of its parts, in the absence of humour, in the
greater overloading of details, in the less graphic and appropriate
characterisation of the speakers. These speakers are three--an
Athenian, a Cretan, and a Spartan. A new colony is to be led forth
from Crete, and the Cretan takes advice of the others as to the
ordering of the new commonwealth. We are no longer, as in _The
Republic_, in an ideal world, a city coming down from, or set in, the
heavens. There is no longer a perfect community; nor are philosophers
to be its kings. Laws more or less similar to those of Sparta fill
about half the book. But the old spirit of obedience and
self-sacrifice and community is not forgotten; and on all men and
women, noble and humble alike, the duty is cast, to bear in common the
common burden of life.

{161}

Thus, somewhat in sadness and decay, yet with a dignity and moral
grandeur not unworthy of his life's high argument, the great procession
of the Ideal Philosopher's dialogues closes.




{162}

CHAPTER XVII

PLATO (_concluded_)

_Search for universals--The thoughts of God--God cause and
consummation--Dying to earth--The Platonic education_


If we attempt now, by way of appendix to this very inadequate summary
of the dialogues, to give in brief review some account of the main
doctrines of Plato, as they may be gathered from a general view of
them, we are at once met by difficulties many and serious. In the case
of a genius such as Plato's, at once ironical, dramatic, and
allegorical, we cannot be absolutely certain that in any given passage
Plato is expressing, at all events adequately and completely, his own
personal views, even at the particular stage of his own mental
development then represented. And when we add to this that in a long
life of unceasing intellectual development, Plato inevitably grew out
of much that once satisfied him, and attained not infrequently to new
points of view even of doctrines or conceptions which remained
essentially unchanged, a Platonic dogma in the strict sense must
clearly not be expected. One may, however, attempt in rough outline to
summarise the main {163} _tendencies_ of his thought, without
professing to represent its settled and authenticated results.

[251]

We may begin by an important summary of Plato's philosophy given by
Aristotle (_Met_. A. 6): "In immediate succession to the Pythagorean
and Eleatic philosophies came the work of Plato. In many respects his
views coincided with these; in some respects, however, he is
independent of the Italians. For in early youth he became a student of
Cratylus and of the school of Heraclitus, and accepted from them the
view that the objects of sense are in eternal flux, and that of these,
therefore, there can be no absolute knowledge. Then came Socrates, who
busied himself only with questions of morals, and not at all with the
world of physics. But in his ethical inquiries his search was ever for
universals, and he was the first to set his mind to the discovery of
definitions. Plato following him in this, came to the conclusion that
these universals could not belong to the things of sense, which were
ever changing, but to some other kind of existences. Thus he came to
conceive of universals as forms or _ideas_ of real existences, by
reference to which, and in consequence of analogies to which, the
things of sense in every case received their names, and became
thinkable objects. "

From this it followed to Plato that in so far as the senses took an
illusive appearance of themselves giving {164} the knowledge which
really was supplied by reason as the organ of ideas, in the same degree
the body which is the instrument of sense can only be a source of
illusion and a hindrance to knowledge. The wise man, therefore, will
seek to free himself from the bonds of the body, and die while he lives
by philosophic contemplation, free as far as possible from the
disturbing influence of the senses. This process of _rational_
realisation Plato called Dialectic. The objects contemplated by the
reason, brought into consciousness on the occurrence of sensible
perception, but never caused by these, were not mere notions in the
mind of the individual thinker, nor were they mere properties of
individual things; this would be to make an end of science on the one
hand, of reality on the other. Nor had they existence in any mere
place, not even beyond the heavens. Their home was Mind, not this mind
or that, but Mind Universal, which is God.

In these 'thoughts of God' was the root or essence which gave reality
to the things of sense; they were the Unity which realised itself in
multiplicity. It is because things partake of the Idea that we give
them a name. The thing as such is seen, not known; the idea as such is
known, not seen.

[252]

The whole conception of Plato in this connection is based on the
assumption that there is such a thing as knowledge. If all things are
ever in change, then knowledge is impossible; but conversely, if there
is {165} such a thing as knowledge, then there must be a continuing
object of knowledge; and beauty, goodness, [253] reality are then no
dreams. The process of apprehension of these 'thoughts of God,' these
eternal objects of knowledge, whether occasioned by sensation or not,
is essentially a process of self-inquiry, or, as he in one stage called
it, of Reminiscence. The process is the same in essence, whether going
on in thought or expressed in speech; it is a process of _naming_. Not
that names ever resemble realities fully; they are only approximations,
limited by the conditions [254] of human error and human convention.
There is nevertheless an inter-communion between ideas and things. We
must neither go entirely with those who affirm the one (the Eleatics),
nor with those who affirm the many (the Heracliteans), but accept both.
There is a union in all that exists both of That Which _Is_, and of
that concerning which all we can say is that it is _Other_ than what
is. This 'Other,' through union with what is, attains to being of a
kind; while on the other hand, What Is by union with the 'Other'
attains to variety, and thus more fully realises itself.

[258]

That which Plato here calls 'What Is' he elsewhere calls 'The Limiting
or Defining'; the 'Other' he calls 'The Unlimited or Undefined. ' Each
has a function in the divine process. The thoughts of God attain
realisation in the world of things which change and pass, through the
infusion {166} of themselves in, or the superimposing of themselves
upon, that which is Nothing apart from them,--the mere negation of what
is, and yet necessary as the 'Other' or correlative of what is. Thus
we get, in fact, _four_ forms of existence: there is the Idea or
Limiting (apart); there is the Negative or Unlimited (apart), there is
the Union of the two (represented in language by subject and
predicate), which as a whole is this frame of things as we know it; and
fourthly, there is the _Cause_ of the Union, which is God. And God is
cause not only as the beginning of all things, but also as the measure
and law of their perfection, and the end towards which they go. He is
the Good, and the cause of Good, and the consummation and realisation
of Good.

This absolute Being, this perfect Good, we cannot see, blinded as we
are, like men that have been dwelling in a cave, by excess of light.
We must, therefore, look on Him indirectly, as on an image of Him, in
our own souls and in the world, in so far as in either we discern, by
reason, that which is rational and good.

[269]

Thus God is not only the cause and the end of all good, He is also the
cause and the end of all knowledge. Even as the sun is not only the
most glorious of all visible objects, but is also the cause of the life
and beauty of all other things, and the provider of the light whereby
we see them, so also {167} is it for the eye of the soul. God is its
light, God is the most glorious object of its contemplation, God we
behold imaged forth in all the objects which the soul by reason
contemplates.

[260]

The ideas whereof the 'Other' (or, as he again calls it, the 'Great and
Small' or 'More and Less,' meaning that which is unnamable, or wholly
neutral in character, and which may therefore be represented equally by
contradictory attributes) by participation becomes a resemblance, Plato
compared to the 'Numbers' of the Pythagoreans (cf. above, p. 25).
Hence, Aristotle remarks (_Met_. A. 6), Plato found in the ideas the
originative or formative Cause of things, that which made them what
they were or could be called,--their _Essence_; in the 'Great and
Small' he found the opposite principle or _Matter_ (Raw Material) of
things.

In this way the antithesis of Mind and Matter, whether on the great
scale in creation or on the small in rational perception, is not an
antithesis of unrelated opposition. Each is correlative of the other,
so to speak as the male and the female; the one is generative,
formative, active, positive; the other is capable of being impregnated,
receptive, passive, negative; but neither can realise itself apart from
the other.

[262]

This relation of 'Being' with that which is 'Other than Being' is
Creation, wherein we can {168} conceive of the world as coming to be,
yet not in [261] Time. And in the same way Plato speaks of a third
form, besides the Idea and that which receives it, namely, 'Formless
Space, the mother of all things. ' As Kant might have formulated it,
Time and Space are not prior to creation, they are forms under which
creation becomes thinkable.

[271]

The 'Other' or Negative element, Plato more or less vaguely connected
with the evil that is in the world. This evil we can never expect to
perish utterly from the world; it must ever be here as the antithesis
of the good. But with the gods it dwells not; here in this mortal
nature, and in this region of mingling, it must of necessity still be
found. The wise man will therefore seek to die to the evil, and while
yet in this world of mortality, to think immortal things, and so as far
as may be flee from the evil. Thereby shall he liken himself to the
divine. For it is a likening to the divine to be just and holy and
true.

[273]

This, then, is the _summum bonum_, the end of life. For as the
excellence or end of any organ or instrument consists in that
perfection of its parts, whereby each separately and the whole together
work well towards the fulfilling of that which it is designed to
accomplish, so the excellence of man must consist in a perfect ordering
of all his parts to the perfect working of his whole organism as a
{169} [276] rational being. The faculties of man are three: the Desire
of the body, the Passion of the heart, the Thought of the soul; the
perfect working of all three, Temperance, Courage, Wisdom, and
consequently the perfect working of the whole man, is Righteousness.
From this springs that ordered tranquillity which is at once true
happiness and perfect virtue.

[277]

Yet since individual men are not self-sufficient, but have separate
capacities, and a need of union for mutual help and comfort, the
perfect realisation of this virtue can only be in a perfect civic [278]
community. And corresponding with the three parts of the man there
will be three orders in the community: the Workers and Traders, the
Soldiers, and the Ruling or Guardian class. When all these perform
their proper functions in perfect harmony, then is the perfection of
the whole realised, in Civic Excellence or Justice.

[281]

To this end a careful civic education is necessary, _first_, because to
_know_ what is for the general good is difficult, for we have to learn
not only in general but in detail that even the individual good can be
secured only through the general; and _second_, because few, if any,
are capable of seeking the general good, even if they know it, without
the guidance of discipline and the restraints of law. Thus, with a
view to its own perfection, and the good of all {170} its members,
Education is the chief work of the State.

It will be remembered (see foregoing page) that in Plato's division of
the soul of man there are three faculties, Desire, Passion, Reason; in
the division of the soul's perfection three corresponding virtues,
Temperance, Courage, Wisdom; and in the division of the state three
corresponding orders, Traders, Soldiers, Guardians. So in Education
there are three stages. First, _Music_ (including all manner of
artistic and refining influences), whose function it is so to attemper
the desires of the heart that all animalism and sensualism may be
eliminated, and only the love and longing for that which is lovely and
of good report may remain. Second, _Gymnastic_, whose function it is
through ordered labour and suffering so to subdue and rationalise the
passionate part of the soul, that it may become the willing and
obedient servant of that which is just and true. And third,
_Mathematics_, by which the rational element of the soul may be trained
to realise itself, being weaned, by the ordered apprehension of the
'diamond net' of laws which underlie all the phenomena of nature, away
from the mere surface appearances of things, the accidental,
individual, momentary,--to the deep-seated realities, which are
necessary, universal, eternal.

And just as there was a perfectness of the soul {171} transcending all
particular virtues, whether of Temperance or Courage or Wisdom, namely,
that absolute Rightness or Righteousness which gathered them all into
itself, so at the end of these three stages of education there is a
higher mood of thought, wherein the soul, purified, chastened,
enlightened, in communing with itself through _Dialectic_ (the Socratic
art of questioning transfigured) communes also with the Divine, and in
thinking out its own deepest thoughts, thinks out the thoughts of the
great Creator Himself, becomes one with Him, finds its final
realisation through absorption into Him, and in His light sees light.




{172}

CHAPTER XVIII

ARISTOTLE

_An unruly pupil--The philosopher's library--The predominance of
Aristotle--Relation to Plato--The highest philosophy--Ideas and
things--The true realism_


Plato before his death bequeathed his Academy to his nephew Speusippus,
who continued its president for eight years; and on his death the
office passed to Xenocrates, who held it for twenty-five years. From
him it passed in succession to Polemo, Crates, Crantor, and others.
Plato was thus the founder of a school or sect of teachers who busied
themselves with commenting, expanding, modifying here and there the
doctrines of the master. Little of their works beyond the names has
been preserved, and indeed we can hardly regret the loss. These men no
doubt did much to popularise the thoughts of their master, and in this
way largely influenced the later development of philosophy; but they
had nothing substantial to add, and so the stern pruning-hook of time
has cut them off from remembrance.

[297]

Aristotle was the son of a Greek physician, member of the colony of
Stagira in Thrace. His father, Nicomachus by name, was a man of such
{173} eminence in his profession as to hold the post of physician to
Amyntas, king of Macedonia, father of Philip the subverter of Greek
freedom. Not only was his father an expert physician, he was also a
student of natural history, and wrote several works on the subject. We
shall find that the fresh element which Aristotle brought to the
Academic philosophy was in a very great measure just that minute
attention to details and keen apprehension of vital phenomena which we
may consider he inherited from his father. He was born 384 B. C. , and
on the death of his father, in his eighteenth year, he came to Athens,
and became a student of philosophy under Plato, whose pupil he
continued to be for twenty years,--indeed till the death of the master.
That he, undoubtedly a far greater man than Speusippus or Xenocrates,
should not have been nominated to the succession has been variously
explained; he is said to have been lacking in respect and gratitude to
the master; Plato is said to have remarked of him that he needed the
curb as much as Xenocrates needed the spur. The facts really need no
explanation. The original genius is never sufficiently subordinate and
amenable to discipline. He is apt to be critical, to startle his
easy-going companions with new and seemingly heterodox views, he is the
'ugly duckling' whom all the virtuous and commonplace brood must cackle
{174} at. The Academy, when its great master died, was no place for
Aristotle. He retired to Atarneus, a city of Mysia opposite to Lesbos,
where a friend named Hermias was tyrant, and there he married Hermias'
niece. After staying at Atarneus some three years he was invited by
Philip, now king of Macedon, to undertake the instruction of his son
Alexander, the future conqueror, who was then thirteen years old. He
remained with Alexander for eight years, though of course he could
hardly be regarded as Alexander's tutor during all that time, since
Alexander at a very early age was called to take a part in public
affairs. However a strong friendship was formed between the
philosopher and the young prince, and in after years Alexander loaded
his former master with benefits. Even while on his march of conquest
through Asia he did not forget him, but sent him from every country
through which he passed specimens which might help him in his projected
History of Animals, as well as an enormous sum of money to aid him in
his investigations.

After the death of Philip, Aristotle returned to Athens, and opened a
school of philosophy on his own account in the Lyceum. Here some
authorities tell us he lectured to his pupils while he paced up and
down before them; hence the epithet applied to the school, the
_Peripatetics_. Probably, however, the name is derived from the
'Peripati' or covered {175} walks in the neighbourhood of that temple
in which he taught. He devoted his mornings to lectures of a more
philosophical and technical character; to these only the abler and more
advanced students were admitted. In the afternoons he lectured on
subjects of a more popular kind--rhetoric, the art of politics,
etc. --to larger audiences. Corresponding with this division, he also
was in the habit of classifying his writings as Acroatic or technical,
and Exoteric or popular. He accumulated a large library and museum, to
which he contributed an astonishing number of works of his own, on
every conceivable branch of knowledge.

The after history of Aristotle's library, including the MSS. of his own
works, is interesting and even romantic. Aristotle's successor in the
school was Theophrastus, who added to the library bequeathed him by
Aristotle many works of his own, and others purchased by him.
Theophrastus bequeathed the entire library to Neleus, his friend and
pupil, who, on leaving Athens to reside at Scepsis in the Troad, took
the library with him. There it remained for nearly two hundred years
in possession of the Neleus family, who kept the collection hidden in a
cellar for fear it should be seized to increase the royal library of
Pergamus. In such a situation the works suffered much harm from worms
and damp, till at last (_circa_ 100 B. C. ) they were brought out {176}
and sold to one Apellicon, a rich gentleman resident in Athens, himself
a member of the Peripatetic school. In 86 B. C. Sulla, the Roman
dictator, besieged and captured Athens, and among other prizes conveyed
the library of Apellicon to Rome, and thus many of the most important
works of Aristotle for the first time were made known to the Roman and
Alexandrian schools. It is a curious circumstance that the philosopher
whose influence was destined to be paramount for more than a thousand
years in the Christian era, was thus deprived by accident of his
legitimate importance in the centuries immediately following his own.

But his temporary and accidental eclipse was amply compensated in the
effect upon the civilised world which he subsequently exercised. So
all-embracing, so systematic, so absolutely complete did his philosophy
appear, that he seemed to after generations to have left nothing more
to discover. He at once attained a supremacy which lasted for some two
thousand years, not only over the Greek-speaking world, but over every
form of the civilisation of that long period, Greek, Roman, Syrian,
Arabic, from the Euphrates to the Atlantic, from Africa to Britain.
His authority was accepted equally by the learned doctors of Moorish
Cordova and the Fathers of the Church; to know Aristotle was to have
all {177} knowledge; not to know him was to be a boor; to deny him was
to be a heretic.

His style has nothing of the grace of Plato; he illuminates his works
with no myths or allegories; his manner is dry, sententious, familiar,
without the slightest attempt at ornament. There are occasional
touches of caustic humour, but nothing of emotion, still less of
rhapsody. His strength lies in the vast architectonic genius by which
he correlates every domain of the knowable in a single scheme, and in
the extraordinary faculty for illustrative detail with which he fills
the scheme in every part. He knows, and can shrewdly criticise every
thinker and writer who has preceded him; he classifies them as he
classifies the mental faculties, the parts of logical speech, the parts
of sophistry, the parts of rhetoric, the parts of animals, the parts of
the soul, the parts of the state; he defines, distinguishes, combines,
classifies, with the same sureness and minuteness of method in them
all. He can start from a general conception, expand it into its parts,
separate these again by distinguishing details till he brings the
matter down to its lowest possible terms, or _infimae species_. Or he
can start from these, find analogies among them constituting more
general species, and so in ascending scale travel surely up to a
general conception, or _summum genus_.

In his general conception of philosophy he was {178} to a large extent
in agreement with Plato; but he endeavoured to attain to a more
technical precision; he sought to systematise into greater
completeness; he pared off everything which he considered merely
metaphorical or fanciful, and therefore non-essential. The operations
of nature, the phenomena of life, were used in a much fuller and more
definite way to illustrate or even formulate the theory; but in its
main ideas Aristotle's philosophy is Plato's philosophy. The one
clothed it in poetry, the other in formulae; the one had a more
entrancing vision, the other a clearer and more exact apprehension; but
there is no essential divergence.

Aristotle's account of the origin or foundation of [300] philosophy is
as follows (_Met_. A. 2): "Wonder is and always has been the first
incentive to philosophy. At first men wondered at what puzzled them
near at hand, then by gradual advance they came to notice and wonder at
things still greater, as at the phases of the moon, the eclipses of sun
and moon, the wonders of the stars, and the origin of the universe.
Now he who is puzzled and in a maze regards himself as a know-nothing;
wherefore the philosopher is apt to be fond of wondrous tales or myths.
And inasmuch as it was a consciousness of ignorance that drove men to
philosophy, it is for the correction of this ignorance, and not for any
material utility, that the pursuit of knowledge exists. Indeed it is,
{179} as a rule, only when all other wants are well supplied that, by
way of ease and recreation, men turn to this inquiry. And thus, since
no satisfaction beyond itself is sought by philosophy, we speak of it
as we speak of the freeman. We call that man free whose existence is
for himself and not for another; so also philosophy is of all the
sciences the only one that is free, for it alone exists for itself.

"Moreover, this philosophy, which is the investigation of the first
causes of things, is the most truly educative among the sciences. For
instructors are persons who show us the causes of things. And
knowledge for the sake of knowledge belongs most properly to that
inquiry which deals with what is most truly a matter of knowledge. For
he who is seeking knowledge for its own sake will choose to have that
knowledge which most truly deserves the name, the knowledge, namely, of
what most truly appertains to knowledge. Now the things that most
truly appertain to knowledge are the first causes; for in virtue of
one's possession of these, and by deduction from these, all else comes
to be known; we do not come to know them through what is inferior to
them and underlying them. . . . The wise man ought therefore to know
not only those things which are the outcome and product of first
causes, he must be possessed of the truth as to the first causes
themselves. And wisdom indeed is just this {180} thoughtful science, a
science of what is highest, not truncated of its head. "

[301]

"To the man, therefore, who has in fullest measure this knowledge of
universals, all knowledge must lie to hand; for in a way he knows all
that underlies them. Yet in a sense these universals are what men find
hardest to apprehend, because they stand at the furthest extremity from
the perceptions of sense. "

[302]

"Yet if anything exist which is eternal, immovable, freed from gross
matter, the contemplative science alone can apprehend this. Physical
science certainly cannot, for physics is of that which is ever in flux;
nor can mathematical science apprehend it; we must look to a mode of
science prior to and higher than both. The objects of physics are
neither unchangeable nor free from matter; the objects of mathematics
are indeed unchangeable, but we can hardly say they are free from
matter; they have certainly relations with matter. But the first and
highest science has to do with that which is unmoved and apart from
matter; its function is with the eternal first causes of things. There
