Religion shows a pattern of heredity which I think is similar to genetic heredity. ... There are hundreds of different religious sects, and every religious person is loyal to just one of these. ... The overwhelming majority just happen to choose the one their parents belonged to. Not the sect that has the best evidence in its favour, the best miracles, the best moral code, the best cathedral, the best stained-glass, the best music when it comes to choosing from the smorgasbord of available religions, their potential virtues seem to count for nothing compared to the matter of heredity.
