6. Two paradoxes which strike the modern reader as in the highest degree fanciful and ideal, and which suggest to him many reflections, are to be found in the third book of the Republic: first, the great power of music, so much beyond any influence which is experienced by us in modern times, when the art or science has been far more developed, and has found the secret of harmony, as well as of melody; secondly, the indefinite and almost absolute control which the soul is supposed to exercise over the body.
In the first we suspect some degree of exaggeration, such as we may also observe among certain masters of the art, not unknown to us, at the present day. With this natural enthusiasm, which is felt by a few only, there seems to mingle in Plato a sort of Pythagorean reverence for numbers and numerical proportion to which Aristotle is a stranger. Intervals of sound and number are to him sacred things which have a law of their own, not dependent on the variations of sense. They rise above sense, and become a connecting link with the world of ideas. But it is evident that Plato is describing what to him appears to be also a fact. The power of a simple and characteristic melody on the impressible mind of the Greek is more than we can easily appreciate. The effect of national airs may bear some comparison with it. And, besides all this, there is a confusion between the harmony of musical notes and the harmony of soul and body, which is so potently inspired by them.
The second paradox leads up to some curious and interesting questions—How far can the mind control the body? Is the relation between them one of mutual antagonism or of mutual harmony? Are they two or one, and is either of them the cause of the other? May we not at times drop the opposition between them, and the mode of describing them, which is so familiar to us, and yet hardly conveys any precise meaning, and try to view this composite creature, man, in a more simple manner? Must we not at any rate admit that there is in human nature a higher and a lower principle, divided by no distinct line, which at times break asunder and take up arms against one another? Or again, they are reconciled and move together, either unconsciously in the ordinary work of life, or consciously in the pursuit of some noble aim, to be attained not without an effort, and for which every thought and nerve are strained. And then the body becomes the good friend or ally, or servant or instrument of the mind. And the mind has often a wonderful and almost superhuman power of banishing disease and weakness and calling out a hidden strength. Reason and the desires, the intellect and the senses are brought into harmony and obedience so as to form a single human being. They are ever parting, ever meeting; and the identity or diversity of their tendencies or operations is for the most part unnoticed by us. When the mind touches the body through the appetites, we acknowledge the responsibility of the one to the other. There is a tendency in us which says 'Drink.' There is another which says, 'Do not drink; it is not good for you.' And we all of us know which is the rightful superior. We are also responsible for our health, although into this sphere there enter some elements of necessity which may be beyond our control. Still even in the management of health, care and thought, continued over many years, may make us almost free agents, if we do not exact too much of ourselves, and if we acknowledge that all human freedom is limited by the laws of nature and of mind.
We are disappointed to find that Plato, in the general condemnation which he passes on the practice of medicine prevailing in his own day, depreciates the effects of diet. He would like to have diseases of a definite character and capable of receiving a definite treatment. He is afraid of invalidism interfering with the business of life. He does not recognize that time is the great healer both of mental and bodily disorders; and that remedies which are gradual and proceed little by little are safer than those which produce a sudden catastrophe. Neither does he see that there is no way in which the mind can more surely influence the body than by the control of eating and drinking; or any other action or occasion of human life on which the higher freedom of the will can be more simple or truly asserted.
7. Lesser matters of style may be remarked.
(1) The affected ignorance of music, which is Plato's way of expressing that he is passing lightly over the subject.
(2) The tentative manner in which here, as in the second book, he proceeds with the construction of the State.
(3) The description of the State sometimes as a reality, and then again as a work of imagination only; these are the arts by which he sustains the reader's interest.
(4) Connecting links, or the preparation for the entire expulsion of the poets in Book X.
(5) The companion pictures of the lover of litigation and the valetudinarian, the satirical jest about the maxim of Phocylides, the manner in which the image of the gold and silver citizens is taken up into the subject, and the argument from the practice of Asclepius, should not escape notice.
BOOK IV. Adeimantus said: 'Suppose a person to argue, Socrates, that you make your citizens miserable, and this by their own free-will; they are the lords of the city, and yet instead of having, like other men, lands and houses and money of their own, they live as mercenaries and are always mounting guard.' You may add, I replied, that they receive no pay but only their food, and have no money to spend on a journey or a mistress. 'Well, and what answer do you give?' My answer is, that our guardians may or may not be the happiest of men,—I should not be surprised to find in the long-run that they were,—but this is not the aim of our constitution, which was designed for the good of the whole and not of any one part. If I went to a sculptor and blamed him for having painted the eye, which is the noblest feature of the face, not purple but black, he would reply: 'The eye must be an eye, and you should look at the statue as a whole.' 'Now I can well imagine a fool's paradise, in which everybody is eating and drinking, clothed in purple and fine linen, and potters lie on sofas and have their wheel at hand, that they may work a little when they please; and cobblers and all the other classes of a State lose their distinctive character. And a State may get on without cobblers; but when the guardians degenerate into boon companions, then the ruin is complete. Remember that we are not talking of peasants keeping holiday, but of a State in which every man is expected to do his own work. The happiness resides not in this or that class, but in the State as a whole. I have another remark to make:—A middle condition is best for artisans; they should have money enough to buy tools, and not enough to be independent of business. And will not the same condition be best for our citizens? If they are poor, they will be mean; if rich, luxurious and lazy; and in neither case contented. 'But then how will our poor city be able to go to war against an enemy who has money?' There may be a difficulty in fighting against one enemy; against two there will be none. In the first place, the contest will be carried on by trained warriors against well-to-do citizens: and is not a regular athlete an easy match for two stout opponents at least? Suppose also, that before engaging we send ambassadors to one of the two cities, saying, 'Silver and gold we have not; do you help us and take our share of the spoil;'—who would fight against the lean, wiry dogs, when they might join with them in preying upon the fatted sheep? 'But if many states join their resources, shall we not be in danger?' I am amused to hear you use the word 'state' of any but our own State. They are 'states,' but not 'a state'—many in one. For in every state there are two hostile nations, rich and poor, which you may set one against the other. But our State, while she remains true to her principles, will be in very deed the mightiest of Hellenic states.
