The State which we have founded must possess the four cardinal virtues of wisdom, courage, discipline and justice ... Justice is the principle which has in fact been followed throughout, the principle of one man one job, of minding one s own business , in the sense of doing the job for which one is naturally fitted and not interfering with other people.
PlatoMisanthropy ariseth from a man trusting another without having sufficient knowledge of his character, and, thinking him to be truthful, sincere, and honourable, finds a little afterwards that he is wicked, faithless, and then he meets with another of the same character. When a man experiences this often, and more particularly from those whom he considered his most dear and best friends, at last, having frequently made a slip, he hates the whole world, and thinks that there is nothing sound at all in any of them.
PlatoMy good friend, you are a citizen of Athens, a city which is very great and very famous for its wisdom and power - are you not ashamed of caring so much for the making of money and for fame and prestige, when you neither think nor care about wisdom and truth and the improvement of your soul?
Plato
