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. … - Robert A. Heinlein

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.

Every time we killed a thousand Bugs at a cost of one M.I. it was a net victory for the Bugs. We were learning, expensively, just how efficient a total communism can be when used by a people actually adapted to it by evolution; the Bug commisars didn't care any more about expending soldiers than we cared about expending ammo. Perhaps we could have figured this out about the Bugs by noting the grief the Chinese Hegemony gave the Russo-Anglo-American Alliance; however the trouble with 'lessons from history' is that we usually read them best after falling flat on our chins.

No intelligent man has any respect for an unjust law. Nor does he feel guilt over breaking it. He simply follows the Eleventh Commandment.
