"Population pressure is the ultimate cause of every war."

“I finished by saying that it struck me that all the ethical systems I was discussing were after the fact. That is, that people act as they are disposed to, but they like to feel afterwards that they were right and so they invent systems that approve of their dispositions.”

“I’ve always resented the word maturity, primarily, I think, because it is most often used as a club. If you do something that someone doesn’t like, you lack maturity, regardless of the actual merits of your action. Too, it seems to me that what is most often called maturity is nothing more than disengagement from life. If you meet life squarely, you are likely to make mistakes, do things you wish you hadn’t, say things you wish you could retract or phrase more felicitously, and, in short, fumble your way along. Those “mature” people whose lives are even without a single sour note or a single mistake, who never fumble, manage only at the cost of original thought and original action. They do without the successes as well as the failures. This has never appealed to me and that is another reason I could never accept the common image of maturity that was presented to me.”

“The rest of our weekend—sleeping arrangements, hand-done work, hand-prepared food—was simple enough to please Thoreau, who I am convinced was a nice fellow who confused rustic vacations with life.”

“Whether or not your actions are determined, you have to act on the assumption that you have free will. If you are determined, your attempt at free will loses you nothing. However, if you are not determined and you act on the assumption that you are, you will never attempt anything. You will simply be a passive blob that things happen to.”

“Some people get a feeling of power from being unpleasant.”

“There’s no reason to trade insults. We have our way of life and they have theirs. I wouldn’t live as they do, but disrespect seems pointless. I’m sure there are good people among them.”
