Since knowledge, thinking, and rational action are properties of the individual, since the choice to exercise his rational faculty or not depends on the individual, man’s survival requires that those who think be free of the interference of those who don’t. Since men are neither omniscient nor infallible, they must be free to agree or disagree, to cooperate or to pursue their own independent course, each according to his own rational judgment. Freedom is the fundamental requirement of man’s mind. A rational mind does not work under compulsion; it does not subordinate its grasp of reality to anyone’s orders, directives, or controls; it does not sacrifice its knowledge, its view of the truth, to anyone’s opinions, threats, wishes, plans, or “welfare.” Such a mind may be hampered by others, it may be silenced, proscribed, imprisoned, or destroyed; it cannot be forced; a gun is not an argument. (An example and symbol of this attitude is Galileo.) It is from the work and the inviolate integrity of such minds—from the intransigent innovators—that all of mankind’s knowledge and achievements have come. (See The Fountainhead.) It is to such minds that mankind owes its survival. (See Atlas Shrugged.) ↗
When confronted by a ‘believer’ it is easy for me to contrast the views of the skeptic with those of the rationalist. I simply reach into my pocket and pull out my change. Holding a quarter aloft, I say, ‘This is a most remarkable coin, for it is heavier than all the sins of humanity committed since the beginning of the human race.’ I then hold up a nickel and say, ‘This coin is even more amazing, as it is brighter and shinier than the flames that proceeded from the Burning Bush discovered on Mt. Sinai by Moses.’ Then I raise a penny and state, ‘This portrait of President Lincoln is more realistic and true-to-life than any portrait of Satan ever painted.’ And finally, I hold out a bright, shiny dime and say, ‘And this dime is the most amazing of all because it is heavier and contains more precious metals than all the gold bricks in the streets of Heaven.’ I end with ‘Give to Caesar what is his, and hold the rest of it dear—for it is all you see and touch—and the Christian god can take care of all his things, for they amount to less than this 41 cents I hold here in my hand. ↗
The sexual mechanisms of the two genders are just not compatible, that’s the horrible truth of it. (...) This is a truth we dare not acknowledge these days - because sameness is our religion and heretics are no more welcome now than they ever were - but I’m going to acknowledge it, because I’ve always felt that humility before the facts is the only thing that keeps a rational man together. Be humble in the face of facts, and proud in the face of opinions, as George Bernard Shaw once said. He didn’t, actually. I just wanted to put some authority behind this observation of mine, because I know you’re not going to like it. ↗
When it is not in our power to determine what is true, we ought to follow what is most probable. ↗

You can't distinguish your group by doing things that are rational and believing things that are true. If you want to set yourself apart from other people you have to do things that are arbitrary and believe things that are false. ↗
Societies would _not_ be better off if everyone were like Mr Spock, all rationality and no emotion. Instead, a balance - a teaming up of the internal rivals - is optimal for brains. ... Some balance of the emotional and rational systems is needed, and that balance may already be optimized by natural selection in human brains. ↗
