And what shall he suffer who slays him who of all men, as they say, is his own best friend? I mean the suicide, who deprives himself by violence of his appointed share of life. Not because the law of the state requires him. Nor yet under the compulsion of some painful and inevitable misfortune which has come upon him. Nor because he has had to suffer from irremediable and intolerable shame, but who from sloth or want of manliness imposes upon himself an unjust penalty.
Plato... what we can be positive about is what we have just said, namely that they must be given the right education, whatever that may be, as the surest way to make them behave humanely to each other and the subjects in their charge.
PlatoVision, in my view, is the cause of the greatest benefit to us, inasmuch as none of the accounts now given concerning the Universe would ever have been given if men had not seen the stars or the sun or the heavens. But as it is, the vision of day and night and of months and circling years has created the art of number and has given us not only the notion of Time but also means of research into the nature of the Universe. From these we have procured Philosophy in all its range, than which no greater boon ever has come or will come, by divine bestowal, unto the race of mortals.
PlatoTheir military training will ensure success in war, but they must maintain unity by not allowing the state to grow to large, and by ensuring that the measures for promotion and demotion from one class to another are carried out. Above all they must maintain the educational system unchanged; for on education everything else depends, and it is an illusion to imagine that mere legislation without it can effect anything of consequence.
