Quote by Descartes, René

"I think, therefore I am."

"The greatest minds are capable of the greatest vices as well as of the greatest virtues."

"Doubt is the key to knowledge."

"If you would be a real seeker of truth, it is necessary that at least once in your life you doubt, as far as possible, all things."

"I love my wife, but sometimes she drives me crazy."

"Love conquers all obstacles."

"Love is patient, love is kind."

"I'm not stupid, I'm just in love!"
