"Somewhere, something incredible is waiting to be known."

"I consider it an extremely dangerous doctrine, because the more likely we are to assume that the solution comes from the outside, the less likely we are to solve our problems ourselves."

"A celibate clergy is an especially good idea, because it tends to suppress any hereditary propensity toward fanaticism."

"Science is a way of thinking much more than it is a body of knowledge."
