I am that gadfly which God has attached to the state, and all day long and in all places am always fastening upon you, arousing and persuading and reproaching you.

If one knows what is right, he will do it; nobody wants to be evil

An honest man is always a child.

I know what I do not know.

The noblest worship is to make yourself as good and as just as you can.

The only place where success comes before work is in the dictionary.There is only one good, knowledge, and one evil, ignorance.

I know that I am intelligent, because I know that I know nothing.
