I have a book-ish nature. I understand faith the way C.S. Lewis did, which is that I like books that help explain the world to me. A lot of theology helps explain the world. I think reading theology is one of the most rewarding things I did in the course of researching this book. Some of it was by Rabbi Joseph Soloveitchik. I read a lot of C.S. Lewis, Augustine, Harry Emerson Fosdickā€™s ‘On Becoming a Real Person.’ Those books were amazingly useful and were a great education. I wish there were more theology and more religion in the public square for the faithful and those who are not faithful.
