The physicist John Wheeler, who helped develop the hydrogen bomb, once observed that “as our island of knowledge grows, so does the shore of our ignorance.” In other words, each victory and advancement that made Khan smarter also bumped him against new situations he’d never encountered before. It takes a special kind of humility to grasp that you know less, even as you know and grasp more and more. It’s remembering Socrates’ wisdom lay in the fact that he knew that he knew next to nothing.
