And now let us enquire, what is the faculty in man which answers to imitation. Allow me to explain my meaning: Objects are differently seen when in the water and when out of the water, when near and when at a distance; and the painter or juggler makes use of this variation to impose upon us. And the art of measuring and weighing and calculating comes in to save our bewildered minds from the power of appearance; for, as we were saying, two contrary opinions of the same about the same and at the same time, cannot both of them be true. But which of them is true is determined by the art of calculation; and this is allied to the better faculty in the soul, as the arts of imitation are to the worse. And the same holds of the ear as well as of the eye, of poetry as well as painting. The imitation is of actions voluntary or involuntary, in which there is an expectation of a good or bad result, and present experience of pleasure and pain. But is a man in harmony with himself when he is the subject of these conflicting influences? Is there not rather a contradiction in him? Let me further ask, whether he is more likely to control sorrow when he is alone or when he is in company. 'In the latter case.' Feeling would lead him to indulge his sorrow, but reason and law control him and enjoin patience; since he cannot know whether his affliction is good or evil, and no human thing is of any great consequence, while sorrow is certainly a hindrance to good counsel. For when we stumble, we should not, like children, make an uproar; we should take the measures which reason prescribes, not raising a lament, but finding a cure. And the better part of us is ready to follow reason, while the irrational principle is full of sorrow and distraction at the recollection of our troubles. Unfortunately, however, this latter furnishes the chief materials of the imitative arts. Whereas reason is ever in repose and cannot easily be displayed, especially to a mixed multitude who have no experience of her. Thus the poet is like the painter in two ways: first he paints an inferior degree of truth, and secondly, he is concerned with an inferior part of the soul. He indulges the feelings, while he enfeebles the reason; and we refuse to allow him to have authority over the mind of man; for he has no measure of greater and less, and is a maker of images and very far gone from truth.

But we have not yet mentioned the heaviest count in the indictment—the power which poetry has of injuriously exciting the feelings. When we hear some passage in which a hero laments his sufferings at tedious length, you know that we sympathize with him and praise the poet; and yet in our own sorrows such an exhibition of feeling is regarded as effeminate and unmanly (Ion). Now, ought a man to feel pleasure in seeing another do what he hates and abominates in himself? Is he not giving way to a sentiment which in his own case he would control?—he is off his guard because the sorrow is another's; and he thinks that he may indulge his feelings without disgrace, and will be the gainer by the pleasure. But the inevitable consequence is that he who begins by weeping at the sorrows of others, will end by weeping at his own. The same is true of comedy,—you may often laugh at buffoonery which you would be ashamed to utter, and the love of coarse merriment on the stage will at last turn you into a buffoon at home. Poetry feeds and waters the passions and desires; she lets them rule instead of ruling them. And therefore, when we hear the encomiasts of Homer affirming that he is the educator of Hellas, and that all life should be regulated by his precepts, we may allow the excellence of their intentions, and agree with them in thinking Homer a great poet and tragedian. But we shall continue to prohibit all poetry which goes beyond hymns to the Gods and praises of famous men. Not pleasure and pain, but law and reason shall rule in our State.

These are our grounds for expelling poetry; but lest she should charge us with discourtesy, let us also make an apology to her. We will remind her that there is an ancient quarrel between poetry and philosophy, of which there are many traces in the writings of the poets, such as the saying of 'the she-dog, yelping at her mistress,' and 'the philosophers who are ready to circumvent Zeus,' and 'the philosophers who are paupers.' Nevertheless we bear her no ill-will, and will gladly allow her to return upon condition that she makes a defence of herself in verse; and her supporters who are not poets may speak in prose. We confess her charms; but if she cannot show that she is useful as well as delightful, like rational lovers, we must renounce our love, though endeared to us by early associations. Having come to years of discretion, we know that poetry is not truth, and that a man should be careful how he introduces her to that state or constitution which he himself is; for there is a mighty issue at stake—no less than the good or evil of a human soul. And it is not worth while to forsake justice and virtue for the attractions of poetry, any more than for the sake of honour or wealth. 'I agree with you.'

And yet the rewards of virtue are greater far than I have described. 'And can we conceive things greater still?' Not, perhaps, in this brief span of life: but should an immortal being care about anything short of eternity? 'I do not understand what you mean?' Do you not know that the soul is immortal? 'Surely you are not prepared to prove that?' Indeed I am. 'Then let me hear this argument, of which you make so light.'

You would admit that everything has an element of good and of evil. In all things there is an inherent corruption; and if this cannot destroy them, nothing else will. The soul too has her own corrupting principles, which are injustice, intemperance, cowardice, and the like. But none of these destroy the soul in the same sense that disease destroys the body. The soul may be full of all iniquities, but is not, by reason of them, brought any nearer to death. Nothing which was not destroyed from within ever perished by external affection of evil. The body, which is one thing, cannot be destroyed by food, which is another, unless the badness of the food is communicated to the body. Neither can the soul, which is one thing, be corrupted by the body, which is another, unless she herself is infected. And as no bodily evil can infect the soul, neither can any bodily evil, whether disease or violence, or any other destroy the soul, unless it can be shown to render her unholy and unjust. But no one will ever prove that the souls of men become more unjust when they die. If a person has the audacity to say the contrary, the answer is—Then why do criminals require the hand of the executioner, and not die of themselves? 'Truly,' he said, 'injustice would not be very terrible if it brought a cessation of evil; but I rather believe that the injustice which murders others may tend to quicken and stimulate the life of the unjust.' You are quite right. If sin which is her own natural and inherent evil cannot destroy the soul, hardly will anything else destroy her. But the soul which cannot be destroyed either by internal or external evil must be immortal and everlasting. And if this be true, souls will always exist in the same number. They cannot diminish, because they cannot be destroyed; nor yet increase, for the increase of the immortal must come from something mortal, and so all would end in immortality. Neither is the soul variable and diverse; for that which is immortal must be of the fairest and simplest composition. If we would conceive her truly, and so behold justice and injustice in their own nature, she must be viewed by the light of reason pure as at birth, or as she is reflected in philosophy when holding converse with the divine and immortal and eternal. In her present condition we see her only like the sea-god Glaucus, bruised and maimed in the sea which is the world, and covered with shells and stones which are incrusted upon her from the entertainments of earth.
