Wonder is the beginning of all wisdom.

I know you won't believe me, but the highest form of Human Excellence is to question oneself and others.

Some have courage in pleasures, and some in pains: some in desires, and some in fears, and some are cowards under the same conditions.

Who knows if to live is to be dead, and to be dead, to live? And we really, it may be, are dead; in fact I once heard sages say that we are now dead, and the body is our tomb.

Well I am certainly wiser than this man. It is only too likely that neither of us has any knowledge to boast of; but he thinks that he knows something which he does not know, whereas I am quite conscious of my ignorance. At any rate it seems that I am wiser than he is to this small extent, that I do not think that I know what I do not know.

The difficulty, my friends, is not in avoiding death, but in avoiding unrighteousness; for that runs faster than death.

An honest man is always a child.
