Then the same person will hardly be able to play a serious part in life, and at the same time to be an imitator and imitate many other parts as well; for even when two species of imitation are nearly allied, the same persons cannot succeed in both, as, for example, the writers of tragedy and comedy--did you not just now call them imitations?
If then we adhere to our original notion and bear in mind that our guardians, setting aside every other business, are to dedicate themselves wholly to the maintenance of freedom in the State, making this their craft, and engaging in no work which does not bear on this end, they ought not to practise or imitate anything else; if they imitate at all, they should imitate from youth upward only those characters which are suitable to their profession-- the courageous, temperate, holy, free, and the like; but they should not depict or be skilful at imitating any kind of illiberality or baseness, lest from imitation they should come to be what they imitate.
Then, I said, we will not allow those for whom we profess a care and of whom we say that they ought to be good men, to imitate a woman, whether young or old, quarrelling with her husband, or striving and vaunting against the gods in conceit of her happiness, or when she is in affliction, or sorrow, or weeping; and certainly not one who is in sickness, love, or labour.
Neither should they be trained to imitate the action or speech of men or women who are mad or bad; for madness, like vice, is to be known but not to be practised or imitated.
Neither may they imitate smiths or other artificers, or oarsmen, or boatswains, or the like?
Nor may they imitate the neighing of horses, the bellowing of bulls, the murmur of rivers and roll of the ocean, thunder, and all that sort of thing?
But there is another sort of character who will narrate anything, and, the worse lie is, the more unscrupulous he will be; nothing will be too bad for him: and he will be ready to imitate anything, not as a joke, but in right good earnest, and before a large company.
