...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.
HesiodIn the race for wealth, a neighbor tries to outdo his neighbor, but this strife is good for men. For the potter envies potter, and the carpenter the carpenter, and the beggar rivals the beggar, and the singer the singer.
Hesiod
