“I write because it’s a way of puzzling out answers to situations in the world that I don’t understand. The act of writing a book gives me the same experience that I hope reading it gives readers. It forces me to sort through the various points of view on a given issue or situation and ultimately come to a conclusion. Doing that might not change my mind, but it almost always gives me a stronger sense of why my opinion is what it is—a question we rarely ask ourselves.”
