Every one of the world's "great" religions utterly trivializes the immensity and beauty of the cosmos. Books like the Bible and the Koran get almost every significant fact about us and our world wrong. Every scientific domain -- from cosmology to psychology to economics -- has superseded and surpassed the wisdom of Scripture. Everything of value that people get from religion can be had more honestly, without presuming anything on insufficient evidence. The rest is self-deception, set to music.
Sam HarrisOur moral reasoning is plagued by two illusions. The first illusion can be called the wag-the-dog illusion: We believe that our own moral judgment (the dog) is driven by our own moral reasoning (the tail). The second illusion can be called the wag-theother-dog's-tail illusion: In a moral argument, we expect the successful rebuttal of an opponent's arguments to change the opponent's mind. Such a belief is like thinking that forcing a dog's tail to wag by moving it with your hand will make the dog happy.
Sam HarrisSome propositions are so dangerous that it may even be ethical to kill people for believing them.
