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."

"Never underestimate the power of a good laugh."

"Laughter is the best medicine."

"A good laugh is the best medicine."

"Laughter is contagious and wonderful."
