"Life is very full of sex, or should be. As much as I admire Tolkien - and I do, he was a giant of fantasy and a giant of literature, and I think he wrote a great book that will be read for many years - you do have to wonder where all those Hobbits came from, since you can't imagine Hobbits having sex, can you? Well, sex is an important part of who we are. It drives us, it motivates us, it makes us do sometimes very noble things and it makes us do sometimes incredibly stupid things. Leave it out, and you've got an incomplete world."
