Quote by Pierre-Simon Laplace

"I had no need of that hypothesis."

"The weight of evidence for an extraordinary claim must be proportioned to its strangeness."

"What we know is not much. What we do not know is immense."

"If we ought to have a fear of anything, we ought to have a fear of want of knowledge rather than of scepticism."

"Education opens doors."

"Education opens doors to endless possibilities."

"I ain't got the education you got, bub."

"You can't put a price on history."
