In 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.
HesiodThe man who does evil to another does evil to himself, and the evil counsel is most evil for him who counsels it.
HesiodBut they who give straight judgements to strangers and to those of the land and do not transgress what is just, for them the city flourishes and its people prosper.
Hesiod
