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've seen a lot of things in my time."

"That's how we archaeologists tell time."

"We must learn from history or be doomed to repeat it."

"Every artifact tells a story."
