"Never tell the truth to people who are not worthy of it."
"Always do what is right. It will gratify half of mankind and astound the other."
"A person with a new idea is a crank until the idea succeeds."
"A big leather-bound volume makes an ideal razorstrap. A thing book is useful to stick under a table with a broken caster to steady it. A large, flat atlas can be used to cover a window with a broken pane. And a thick, old-fashioned heavy book with a clasp is the finest thing in the world to throw at a noisy cat."
