“I was no fool; I was aware that when another man is too anxious to force money on one, it is time to examine the cards, for there is almost certainly something illegal, or dangerous, or both, involved in the matter.”

“For the first time in my life, I was reading things which had not been approved by the Prophet's censors, and the impact on my mind was devastating. Sometimes I would glance over my shoulder to see who was watching me, frightened in spite of myself. I began to sense faintly that secrecy is the keystone of all tyranny. Not force, but secrecy...censorship. When any government, or any church for that matter, undertakes to say to it's subjects, This you may not read, this you must not see, this you are forbidden to know, the end result is tyranny and oppression, no matter how holy the motives. Mighty little force is needed to control a man whose mind has been hoodwinked, contrariwise, no amount of force can control a free man, a man whose mind is free. No, not the rack, not fission bombs, not anything---you can't conquer a free man; the most you can do is kill him.”

Mighty little force is needed to control a man who has been hoodwinked in this fashion; contrariwise, no amount of force can control a free man, whose mind is free. No, not the rack nor the atomic bomb, not anything. You can't conquer a free man; the most you can do is kill him.”

“One man's theology is another man's belly laugh.”

“Listen, son. Most women are damn fools and children. But they've got more range then we've got. The brave ones are braver, the good ones are better — and the vile ones are viler, for that matter. ”

“Many older physicians had gone to their graves calling Pasteur a liar, a fool, or worse---and without examining evidence which their “common sense” told them was impossible.”

“No matter what I said they insisted on thinking of God as something outside themselves. Something that yearns to take every indolent moron to His breast and comfort him. The notion that the effort has to be their own . . . and that the trouble they are in is all their own doing . . . is one that they can't or won't entertain.”
