In The Moral Animal, author Robert Wright uses Charles Darwin's life to demonstrate that human animals share values with other species. He points out that good monkey Darwin, for all that his ideas shocked the world, was very careful about his approach to relationships and to expressing his ideas. Darwin held back for 20 years announcing the facts he'd gathered because he didn't want to destroy his wife's faith, and he was choosy about his friends. As Darwin's influence and friendships grew among the intellects of his time, he slowly dropped friendships with people who were not as well known as he. Darwin did not consciously reject them. It just happened. The more he was caught up in success, the less time he had for many old friends. (Recall Woody Allen's Stardust Memories when an old neighborhood pal comes up to Sandy Bates and asks Bates if Bates remembers him? Pow!)
