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.

Nothing is good for him for whom nothing is bad.

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

An ounce of prudence is worth a pound of cleverness.

Friendship multiplies the good of life and divides the evil.

Oh life, you should never had begun, but since you did, you should never end

Knowledge without wisdom is double folly.
