. . . for until that God who rules all the region of the sky . . . has freed you from the fetters of your body, you cannot gain admission here. Men were created with the understanding that they were to look after that sphere called Earth, which you see in the middle of the temple. Minds have been given to them out of the eternal fires you call fixed stars and planets, those spherical solids which, quickened with divine minds, journey through their circuits and orbits with amazing speed.

In nothing do men more nearly approach the gods than in giving health to men.

Friendship is nothing else than entire fellow feeling as to all things human and divine with mutual good-will and affection; and I doubt whether anything better than this, wisdom alone excepted, has been given to man.

An unjust peace is better than a just war.

We are bound by the law, so that we may be free.

There is no moment without some duty.

Man is his own worst enemy.
