I Want to be a Mathematician: An Automathography (1985)
Context: Mathematics is not a deductive science — that's a cliché. When you try to prove a theorem, you don't just list the hypotheses, and then start to reason. What you do is trial and error, experimentation, guesswork. You want to find out what the facts are, and what you do is in that respect similar to what a laboratory technician does. Possibly philosophers would look on us mathematicians the same way as we look on the technicians, if they dared.

Context: There's a kind of saying that you don't understand its meaning, 'I don't believe it. It's too crazy. I'm not going to accept it.'… You'll have to accept it. It's the way nature works. If you want to know how nature works, we looked at it, carefully. Looking at it, that's the way it looks. You don't like it? Go somewhere else, to another universe where the rules are simpler, philosophically more pleasing, more psychologically easy. I can't help it, okay? If I'm going to tell you honestly what the world looks like to the human beings who have struggled as hard as they can to understand it, I can only tell you what it looks like.

Context: I'm always astounded at the way we automatically look at what divides and separates us. We never look at what people have in common. If you see it, black and white people, both sides look to see the differences, they don't look at what they have together. Men and women, and old and young, and so on. And this is a disease of the mind, the way I see it. Because in actual fact, men and women have much more in common than they are separated.
