“There’s a constant issue of tone: who do you want to read these pieces, and how do you want them to be read? I can write them in a way that is deeply satisfying to a professor of philosophy at Princeton, but we all know if I do that I’ll lose everybody else, and I can do it at the other end of the spectrum for a 10-year-old. You have to pick where you want to be, which for me is somewhere around the middle. Maybe a little to one side of the middle.”
