Again, Plato objects to the imitative arts that they express the emotional rather than the rational part of human nature. He does not admit Aristotle's theory, that tragedy or other serious imitations are a purgation of the passions by pity and fear; to him they appear only to afford the opportunity of indulging them. Yet we must acknowledge that we may sometimes cure disordered emotions by giving expression to them; and that they often gain strength when pent up within our own breast. It is not every indulgence of the feelings which is to be condemned. For there may be a gratification of the higher as well as of the lower--thoughts which are too deep or too sad to be expressed by ourselves, may find an utterance in the words of poets. Every one would acknowledge that there have been times when they were consoled and elevated by beautiful music or by the sublimity of architecture or by the peacefulness of nature. Plato has himself admitted, in the earlier part of the Republic, that the arts might have the effect of harmonizing as well as of enervating the mind; but in the Tenth Book he regards them through a Stoic or Puritan medium. He asks only 'What good have they done?' and is not satisfied with the reply, that 'They have given innocent pleasure to mankind.' He tells us that he rejoices in the banishment of the poets, since he has found by the analysis of the soul that they are concerned with the inferior faculties. He means to say that {clx} the higher faculties have to do with universals, the lower with particulars of sense. The poets are on a level with their own age, but not on a level with Socrates and Plato; and he was well aware that Homer and Hesiod could not be made a rule of life by any process of legitimate interpretation; his ironical use of them is in fact a denial of their authority; he saw, too, that the poets were not critics--as he says in the Apology, 'Any one was a better interpreter of their writings than they were themselves' (22 C). He himself ceased to be a poet when he became a disciple of Socrates; though, as he tells us of Solon, 'he might have been one of the greatest of them, if he had not been deterred by other pursuits' (Tim. 21 C) Thus from many points of view there is an antagonism between Plato and the poets, which was foreshadowed to him in the old quarrel between philosophy and poetry. The poets, as he says in the Protagoras (316 E), were the Sophists of their day; and his dislike of the one class is reflected on the other. He regards them both as the enemies of reasoning and abstraction, though in the case of Euripides more with reference to his immoral sentiments about tyrants and the like. For Plato is the prophet who 'came into the world to convince men'--first of the fallibility of sense and opinion, and secondly of the reality of abstract ideas. Whatever strangeness there may be in modern times in opposing philosophy to poetry, which to us seem to have so many
