Justice is having and doing what is one's own.

A man is not learned until he can read, write and swim.

Your dog is your only philosopher.

O youth or young man, who fancy that you are neglected by the gods, know that if you become worse, you shall go to worse souls, or if better to the better... In every succession of life and death, you will do and suffer what like may fitly suffer at the hands of like. This is the justice of heaven.

Worthy of honor is he who does no injustice, and more than twofold honor, if he not only does no injustice himself, but hinders others from doing any.

Time on its back bears all things far away - Full many a challenge is wrought by many a day - Shape, fortune, name, and nature all decay

And all knowledge, when separated from justice and virtue, is seen to be cunning and not wisdom; wherefore make this your first and last and constant and all-absorbing aim, to exceed, if possible, not only us but all your ancestors in virtue; and know that to excel you in virtue only brings us shame, but that to be excelled by you is a source of happiness to us.
