“A slave cannot be freed, save he do it himself. Nor can you enslave a free man; the very most you can do is kill him!”

“Secrecy is the keystone to all tyranny. Not force, but secrecy and censorship. When any government or church for that matter, undertakes to say to its subjects, "This you may not read, this you must not know," the end result is tyranny and oppression, no matter how holy the motives. 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.”

“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.”

“From somewhere, back in my youth, heard Prof say, 'Manuel, when faced with a problem you do not understand, do any part of it you do understand, then look at it again.' He had been teaching me something he himself did not understand very well—something in math—but had taught me something far more important, a basic principle.”

“A little more money won't do you any good - because daughters can use up ten percent more than a man can make in any normal occupation, regardless of the amount.”

“The more you love, the more you can love--and the more intensely you love. Nor is there any limit on how many you can love. If a person had time enough, he could love all of that majority who are decent and just.”

“Correct morality can only be derived from what man is — not from what do-gooders and well-meaning aunt Nellies would like him to be.”
