"A fish out of water is not more helpless than a man without an education."

"A mind that is stretched by a new experience can never go back to its old dimensions."

"Folly is the only thing that keeps men from despair."

"It is not every question that deserves an answer."

"But if anyone thinks that it is a foolish thing to be wise, let him be advised that it is a much more foolish thing to be foolish."
