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 acc.u.mulate 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 G.o.d's thought, which is equivalent to the order of G.o.d's working; for G.o.d's thought and G.o.d'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 quant.i.tative 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.

With the _Timaeus_ is a.s.sociated 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).

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 a.n.a.lysis 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 cla.s.sifications 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 antic.i.p.ation 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 a.n.a.logy 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 G.o.d, to the same ideas as possessed by individual men? Does each individual actually _partake_ in the thought of G.o.d 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 G.o.d 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 a.n.a.lysis 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 a.n.a.lysis of Parmenides and the philosophy of Hegel are both founded.

We may pa.s.s 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 a.n.a.lysis 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 cla.s.sification, the theory of predication, the processes of induction and deduction, the cla.s.sification 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, n.o.ble 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 G.o.d--G.o.d 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 pa.s.sage 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 Herac.l.i.tus, 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 a.n.a.logies 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 G.o.d.

In these 'thoughts of G.o.d' 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 a.s.sumption 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 G.o.d,' 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 Herac.l.i.teans), 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 G.o.d attain realisation in the world of things which change and pa.s.s, 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 G.o.d. And G.o.d 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 G.o.d 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. G.o.d is its light, G.o.d is the most glorious object of its contemplation, G.o.d 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 partic.i.p.ation becomes a resemblance, Plato compared to the 'Numbers' of the Pythagoreans (cf. above, p. 25).
