Man is born a barbarian, and only raises himself above the beast by culture.

Maturity is the slowness in which a man believes.

Keep the extent of your abilities unknown.The wise man does not allow his knowledge and abilities to be sounded to the bottom, if he desires to be honored at all. He allows you to know them but not to comprehend them. No one must know the extent of his abilities, lest he be disappointed. No one ever has an opportunity of fathoming him entirely. For guesses and doubts about the extent of his talents arouse more veneration than accurate knowledge of them, be they ever so great.

A prudent man will think more important what fate has conceded to him, than what it has denied.

Know what is evil, no matter how worshipped it may be. Let the man of sense not mistake it, even when clothed in brocade, or at times crowned in gold, because it cannot thereby hide its hypocrisy, for slavery does not lose its infamy, however noble the master.

When a man's knowledge is deep, he speaks well of an enemy. Instead of seeking revenge, he extends unexpected generosity. He turns insult into humor, ... and astonishes his adversary who finds no reason not to trust him.
