Anna Karenina

I just finished Anna Karenina. The book was long and boring in spots, but it was amazing. The novel does a great job of interwining the lives of seven main characters. All the characters were believable. I became good friends with them. Even when I wanted to hate them I felt sympathy for them. Levin, the male main character, converts from materialism to spiritualism and perhaps, even Christianity. He has an internal debate with himself throughout the book. He landed on the fact that some people lived for God instead of their belly. Not all people desired to be selfish, but some desired to do good. He thinks this a pointer to God. The argument is not fool proof, but experientially, it is fairly sound. Why are people generous and kind to strangers? Does evolutionary theory really predict benevolence?
