You are wrong, sir, if you think that a man who is any good at all should take into account the risk of life or death; he should look to this only in his actions, whether what he does is right or wrong, whether he is acting like a good or a bad man.

Wisdom is knowing what you don't know.

Why do you wonder that globetrotting does not help you, seeing that you always take yourself with you? The reason that set you wandering is ever at your heels.

To fear death, gentlemen, is no other than to think oneself wise when one is not, to think one knows what one does not know.

When the debate is lost, slander becomes the tool of the loser.

True knowledge exists in knowing that you know nothing.
