Quotes about reason

Once you cared about a person, it was impossible to be logical about them anymore.

I can’t really imagine war. I can imagine having to fight some swarm of zombie machines or snarling horde of posthuman fast-burn wreckage or whatever, but not two or more actual human societies actually fighting each other. I’m aware that people did that, before history, before the Moon, but it seems irrational. One side would have to believe they had something to gain from destroying or damaging the other, which just doesn’t make sense: it runs up against the law of association. And more to the point, each individual on any side would have to believe that they benefited from participating even if they died, which doesn’t make sense either. I suppose kin selection could make genes prevalent that made people vulnerable to that kind of illusion, but that only makes sense with animals that don’t have foresight. Even crows aren’t that stupid, at least not the ones that can talk. You have to get down to ants and such like before you see that kind of genetic mechanical mindlessness.

'''

Nothing can be of more importance than to separate prejudice and mistake on the one hand from reason and demonstration on the other.

People didn’t always follow their best interests. Human beings were distressingly bad at risk analysis, lousy with hidden motivations and neuroses, anything but the clean rational actors that economists or diplomats wanted so desperately to believe in, and diplomats had to go by capabilities, not intentions.

His thinking wasn’t logical. But whatever the philosophers claimed, the main use of logic was to justify your emotions.

No one thing shows the greatness and power of the human intellect or the loftiness and nobility of man more than his ability to know and to understand fully and feel strongly his own smallness. When, in considering the multiplicity of worlds, he feels himself to be an infinitesimal part of a globe which itself is a negligible part of one of the infinite number of systems that go to make up the world, and in considering this is astonished by his own smallness, and in feeling it deeply and regarding it intently, virtually blends into nothing, and it is as if he loses himself in the immensity of things, and finds himself as though lost in the incomprehensible vastness of existence, with this single act and thought he gives the greatest possible proof of the nobility and immense capability of his own mind, which, enclosed in such a small and negligible being, has nonetheless managed to know and understand things so superior to his own nature, and to embrace and contain this same intensity of existence and things in his thought.
