Prefer knowledge to wealth, for the one is transitory, the other perpetual. - Socrates

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. No one knows whether death may not be the greatest of all blessings for a man, yet men fear it as if they knew that it is the greatest of evils. And surely it is the most blameworthy ignorance to believe that one knows what one does not know. It is perhaps on this point and in this respect, gentlemen, that I differ from the majority of men, and if I were to claim that I am wiser than anyone in anything, it would be in this, that, as I have no adequate knowledge of things in the underworld, so I do not think I have. I do know, however, that it is wicked and shameful to do wrong, to disobey one's superior, be he god or man. I shall never fear or avoid things of which I do not know, whether they may not be good rather than things that I know to be bad.

"Someone might say: " Are you not ashamed, Socrates, to have followed the kind of occupation that has led to your being now in danger of death?" Howeverm, I should be right to reply to him: "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 bad man

Let him who would move the world first move himself.
