You are mistaken, my friend, if you think that a man who is worth anything ought to spend his time weighing up the prospects of life and death. He has only one thing to consider in performing any action - that is, whether he is acting rightly or wrongly, like a good man or a bad one.
Man is a prisoner who has no right to open the door of his prison and run away. . . . A man should wait, and not take his own life until God summons hiom.
For the poets tell us, don't they, that the melodies they bring us are gathered from rills that run with honey, out of glens and gardens of the Muses, and they bring them as bees do honey, flying like the bees? And what they say is true, for a poet is a light and winged thing, and holy, and never able to compose until he has become inspired, and is beside himself, and reason is no longer in him. So long as he has this in his possession, no man is able to make poetry or to chant in prophecy.
Take a look around, then, and see that none of the uninitiated are listening. Now by the uninitiated I mean the people who believe in nothing but what they can grasp in their hands, and who will not allow that action or generation or anything invisible can have real existence.
So the state founded on natural principles is wise as a whole in virtue of the knowledge inherent in its smallest constituent class, which exercises authority over the rest. And the smallest class is the one which naturally possesses that form of knowledge which alone of all others deserves the title of wisdom.
Physical excellence does not of itself produce a good mind and character: on the other hand, excellence of mind and character will make the best of the physique it is given.
Because, unlike courage and wisdom, which made our state brave and wise by being present in a particular part of it, discipline operates by being diffused throughout the whole of it. It produces a concord between its strongest and weakest and middle elements, whether you define them by the standard of good sense, or of strength, or of numbers or money or the like. And so we are quite justified in regarding discipline as this sort of natural harmony and agreement between higher and lower about which of them is to rule in state and individual.
True opinions are a fine thing and do all sorts of good so long as they stay in their place; but they will not stay long. They run away from a man's mind, so they are not worth much until you tether them by working out the reason. Once they are tied down, they become knowledge, and are stable.
