Georg Cantor

“In mathematics, the art of proposing a question must be held of higher value than solving it.”

“I see it, but I don't believe it.”

“The fear of infinity is a form of myopia that destroys the possibility of seeing the actual infinite.”

“My theory stands as firm as a rock; every arrow directed against it will return quickly to its archer.”

“The essence of mathematics lies in its freedom.”

“A set is a Many that allows itself to be thought of as a One.”
