As for me, all I know is that I know nothing.
Having the fewest wants, I am nearest to the gods.
I am not an Athenian, nor a Greek, but a citizen of the world.
I know nothing except the fact of my ignorance.
The unexamined life is not worth living.
The way to gain a good reputation, is to endeavour to be what you desire to appear.
There is only one good, knowledge, and one evil, ignorance.
Think not those faithful who praise all thy words and actions; but those who kindly reprove thy faults.
True knowledge exists in knowing that you know nothing.
Wisdom begins in wonder.
