He, O men, is the wisest, who, like Socrates, knows that his wisdom is in truth worth nothing.
Wisest is he who knows what he does not know.
Herein is the evil of ignorance, that he who is neither good nor wise is nevertheless satisfied with himself: he had no desire for that of which he feels no want.
Music is to the mind as air is to the body.
He who wishes to serve his country must have not only the power to think, but the will to act
Truth is its own reward.
