When I was young, everybody was excited by [Kurt] Gödel,87 who came up with proof that you couldn’t have a mathematical system without a lot of irritating incompleteness in it. Well, since then, my betters tell me that they’ve come up with more irremovable defects in mathematics and have decided that you’re never going to get mathematics without some paradox in it. No matter how hard you work, you’re going to have to live with some paradox if you’re a mathematician.
