" My interest in psychology was as a way to do philosophy,” he said. “To understand the world by understanding why people, especially me, see it as they do. By then the question of whether God exists left me cold. But the question of why people believe God exists I found really fascinating. I was not really interested in right and wrong. But I was very interested in indignation. Now that’s a psychologist! "
