“I just think people overvalue argument because they like to hear themselves talk.”

“Often I've thought of myself as a state; a country or, at the very least, a city. It used to seem to me that the different ways I felt sometimes about ideas, courses of action and so on were like the differing political moods that countries go through. It has always seemed to me that people vote in a new government not because they actually agree with their politics but just because they want a change. Somehow they think that things will be better under the new lot. Well, people are stupid, but it all seems to have more to do with mood, caprice and atmosphere than carefully thought-out arguments. I can feel the same sort of thing going on in my head. Sometimes the thoughts and feelings I had didn't really agree with each other, so I decided I must be lots of different people inside my brain.”

“Empathize with stupidity and you're halfway to thinking like an idiot”

“People can be teachers and idiots; they can be philosophers and idiots; they can be politicians and idiots... in fact I think they have to be... a genius can be an idiot. The world is largely run for and by idiots; it is no great handicap in life and in certain areas is actually a distinct advantage and even a prerequisite for advancement.”

“He could not believe that ordinary people in the Culture really wanted the war, no matter how they had voted. They had their communist Utopia. They were soft and pampered and indulged, and the Contact section’s evangelical materialism provided their conscience-salving good works. What more could they want? The war had to be the Mind’s idea; it was part of their clinical drive to clean up the galaxy, make it run on nice, efficient lines, without waste, injustice or suffering. The fools in the Culture couldn’t see that one day the Minds would start thinking how wasteful and inefficient the humans in the Culture themselves were.”

“I'm too drunk to recall much of what I've said. Which, come to think of it, is probably just as well, judging by the way people who are normally quite sensible dissolve into gibbering, rude, opinionated and bombastic idiots once the alcohol molecules in their bloom-stream outnumber the neutrons, or whatever. Luckily, one only notices this if one stays sober oneself, so the solution is as pleasant (at the time, at least) as it is obvious.”

“Any theory which causes solipsism to seem just as likely an explanation for the phenomena it seeks to describe ought to be held in the utmost suspicion.”
