An unexamined life is a life of no account.

Only the knowledge that comes from inside is the real Knowledge

Only the extremely ignorant or the extremely intelligent can resist change.

Virtue does not come from wealth, but wealth, and every other good thing which men have comes from virtue.

Do not grieve over someone who changes all of the sudden. It might be that he has given up acting and returned to his true self.

Aren't you ashamed to be concerned so much about making all the money you can and advancing your reputation and prestige, while for truth and wisdom and the improvement of your souls you have no thought or car?

YOU ARE NOT ONLY GOOD TO YOURSELF, BUT THE CAUSE OF GOODNESS IN OTHERS
