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 versâ. 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.
