Quote by Denis Diderot

"The world is for those who think."

"Man will never be free until the last king is strangled with the entrails of the last priest."

"Nothing can be believed unless it is seen."

"I am convinced the mind can be developed to the point where success is inevitable."

"Perseverance is the key to success."

"Don't give up on what you believe in."

"I've been through worse."

"You learn to live with the pain."
