“One always begins with the simple, then comes the complex, and by superior enlightenment one often reverts in the end to the simple. Such is the course of human intelligence.”

“There is a wide difference between speaking to deceive, and being silent to be impenetrable.”

“There are three types of intelligent persons: the first so intelligent that being called very intelligent must seem natural and obvious; the second sufficiently intelligent to see that he is being flattered, not described; the third so little intelligent that he will believe anything. I knew I belonged to the second kind.”
