Years ago I read a man named Machado de Assis who wrote a book called Dom Casmurro. Machado de Assis is a South American writer—black father, Portuguese mother—writing in 1865, say. I thought the book was very nice. Then I went back and read the book and said, Hmm. I didn’t realize all that was in that book. Then I read it again, and again, and I came to the conclusion that what Machado de Assis had done for me was almost a trick: he had beckoned me onto the beach to watch a sunset. And I had watched the sunset with pleasure. When I turned around to come back in I found that the tide had come in over my head. That’s when I decided to write. I would write so that the reader says, That’s so nice. Oh boy, that’s pretty. Let me read that again.
