The only true wisdom is in knowing you know nothing.

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

Be as you wish to seem.

I am not an Athenian or a Greek, but a citizen of the world.

I'm not afraid of death because I don't believe in it.

An honest man is always a child.

I cannot teach anybody anything. I can only make them think.

Strong minds discuss ideas, average minds discuss events, weak minds discuss people

The fear of death follows from the fear of life. A man who lives fully is prepared to die at any time.
