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."

"You can't expect to be happy if you're surrounded by mess."

"Health and happiness - these are true wealth"

"How can you live like this? It's like a pigsty!"

"You're going to get sick living like this."
