Robert A. Heinlein quotes - page 20
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 its 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.
Robert A. Heinlein
People tend to fall into three psychological types, all differently motivated. There is the type, motivated by economic factors, money...And there is the type motivated by ‘face,' or pride. This type is a spender, fighter, boaster, lover, sportsman, gambler; he has a will to power and an itch for glory. And there is the professional type, which claims to follow a code of ethics rather than simply seeking money or glory-priests and ministers, teachers, scientists, medical men, some artists and writers. The idea is that such a man believes that he is devoting his life to some purpose more important than his individual self. You follow me?
