Socrates

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

"For I go about doing nothing else than urging you, young and old, not to care for your persons or your property more than for the perfection of your souls, or even so much; and I tell you that virtue does not come from money, but from virtue comes money and all other good things to man, both the individual and to the state."

"Oh my friend, why do you, who are a citizen of the great and mighty and wise city of Athens, care so much about laying up the greatest amount of money and honour and reputation, and so little about wisdom and truth and the greatest improvement of the soul, which you never regard or heed at all? Are you not ashamed of this?"

"I cannot teach anyone anything, I can only make them think."

"Our prayers should be for blessings in general, for God knows best what is good for us."
