“Pain pays the income of each precious thing.”

“Things keep their secrets.”

“Experiment is the sole interpreter of the artifices of Nature.”

“There is no history of how bad became better.”

“Il n'est pas certain que tout soit incertain. (Translation: It is not certain that everything is uncertain.)”

“He seemed so certain about everything, didn't he? And yet none of his certainties was worth one hair of a woman's head. He wasn't even sure he was alive, because he was living like a dead man.”

“It is unwise to be too sure of one's own wisdom.”
