No man's nature is able to know what is best for the social state of man; or, knowing, always able to do what is best.
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
