"There is only one good, knowledge, and one evil, ignorance."

“[Why is suicide held not to be right?] There is a doctrine uttered in secret that a man is a prisoner who has no right to open the door to his prison and run away; this is a great mystery which I do not understand. Yet I too, believe that the gods are our guardians, and that we are a possession of theirs. ...And if one of your possessions, an ox or an ass, for example took the liberty of putting himself out of the way when you had given no intimation of your wish that he should die, would you not be angry with him, and would you not punish him if you could? ...Then there may be reason in saying that a man should wait, and not take his own life until God summons him, as he is now summoning me.”

“One should never do wrong in return, nor mistreat any man, no matter how one has been mistreated by him.”

“I only wish that wisdom were the kind of thing that flowed ... from the vessel that was full to the one that was empty.”

“I would rather die having spoken in my manner, than speak in your manner and live. For neither in war nor yet in law ought any man use every way of escaping death. For often in battle there is no doubt that if a man will throw away his arms, and fall on his knees before his pursuers, he may escape death, if a man is willing to say or do anything. The difficulty, my friends, is not in avoiding death, but in avoiding unrighteousness; for that runs deeper than death.”

“He would say that the rest of the world lived to eat, while he himself ate to live.”

“He who has lived as a true philosopher has reason to be of good cheer when he is about to die, and that after death he may hope to receive the greatest good in the other world.”
