"The malice of a true Christian attempting to destroy an opponent is something unique in the world. No other religion ever considered it necessary to destroy others because they did not share the same beliefs. At worst, another man's belief might inspire amusement or contempt—the Egyptians and their animal gods, for instance. Yet those who worshipped the Bull did not try to murder those who worshipped the Snake, or to convert them by force from Snake to Bull. No evil ever entered the world quite so vividly or on such a vast scale as Christianity did."

“Private lives should be no business of the State. The State is bad enough as it is. It cannot educate or medicate or feed the people; it cannot do anything but kill the people. No State like that do we want prying into our private lives.”

“I used to be able to summon up scenes at will, but now aging memory is so busy weeding its own garden that, promiscuously, it pulls up roses as well as crabgrass.”

“On the throne of the world, any delusion becomes fact.”

“His fault was a common one. He simply did not know what he was;he saw no flaw in himself, a not unusual blindness and preferable, on the whole , to being unable to find any virtue in oneself.”

“In a good cause hypocrisy becomes a virtue.”

“The United States was founded by the brightest people in the country — and we haven't seen them since.”
