“My friend...care for your psyche...know thyself, for once we know ourselves, we may learn how to care for ourselves" -Socrates”

“Know thyself.”

“True wisdom comes to each of us when we realize how little we understand about life, ourselves, and the world around us.”

“To know thyself is the beginning of wisdom.”

“To move the world we must move ourselves.”

“Esteemed friend, citizen of Athens, the greatest city in the world, so outstanding in both intelligence and power, aren't you ashamed to care so much to make all the money you can, and to advance your reputation and prestige--while for truth and wisdom and the improvement of your soul you have no care or worry?”

“Are you not ashamed of caring so much for the making of money and for fame and prestige, when you neither think nor care about wisdom and truth and the improvement of your soul?”
