“Our lives teach us who we are.”

“When one is a stranger to oneself then one is estranged from others too.”

“I want, by understanding myself, to understand others. I want to be all that I am capable of becoming.”

“To grow wiser means to learn to know better and better the faults to which this instrument with which we feel and judge can be subject.”

“Without self knowledge, without understanding the working and functions of his machine, man cannot be free, he cannot govern himself and he will always remain a slave.”

“Beauty is a short-lived tyranny.”

“Happiness is unrepentant pleasure.”

“Fame is the perfume of heroic deeds.”

“The hottest love has the coldest end.”

“To find yourself, think for yourself.”

“An unexamined life is not worth living.”
