I think when you say to someone You are fool not to believe in evolution or a fool to believe the universe is 6000 years old. I think that gets translated as You are a fool to think that your daughter who died in a car accident is really in heaven with god.
Sam HarrisScience, in the broadest sense, includes all reasonable claims to knowledge about ourselves and the world.
Sam HarrisIt is rather more noble to help people purely out of concern for their suffering than it is to help them because you think the Creator of the Universe wants you to do it, or will reward you for doing it, or will punish you for not doing it. The problem with this linkage between religion and morality is that it gives people bad reasons to help other human beings when good reasons are available.
