The best man of all is he who knows everything himself. Good also the man who accepts another's sound advice; but the man who neither knows himself nor takes to hear what another says, he is no good at all.
HesiodIt is a hard thing for a man to be righteous, if the unrighteous man is to have the greater right.
Hesiod...Perses, hear me out on justice, and take what I have to say to heart; cease thinking of violence. For the son of Kronos, Zeus, has ordained this law to men: that fishes and wild beasts and winged birds should devour one another, since there is no justice in them; but to mankind he gave justice which proves for the best.
