When Orpheus, the legendary musician, poet and prophet, had his head torn off his shoulders and thrown into the river Hebrus, he kept singing as his head was carried along by the strong current. It's impossible to kill off some voices. Sometimes, the dead don't realize they're dead. God is dead, but doesn't know it. His morality is dead with him, but all across the world people still hear morality's ghostly voice and mistake it for something real and objective.Some people believe that God is the center of the moral universe. In fact, God is not moral at all. In this book, we rationally explore how it is impossible for either God or the Devil to serve any moral role whatsoever.Some people believe in moral realism (moral objectivism) - the claim that objective moral facts and moral values exist like Platonic Forms, independently of our perception of them or our feelings, beliefs, opinions or subjective attitudes towards them. Moral facts are deemed as real as mathematical facts, and moral judgments as certain as mathematical proofs. In fact, only mathematical facts are real. All other "facts" are manmade interpretations. As Nietzsche said, "There are no facts, only interpretations. ... There are no moral phenomena at all, but only a moral interpretation of phenomena."Mainstream religion, and its attendant morality, is the biggest possible misinterpretation of mathematical reality. People would behave entirely differently if they realized they inhabited a mathematical universe engaged in solving itself rather than a moral universe offering them a binary choice of heaven or hell, or positive or negative karma.Reality is about the optimization of knowledge, of understanding, of reason and logic. It is not about the optimization or minimization of "good" or "evil," which are just subjective human terms and labels. As Oscar Wilde said, "Morality is simply the attitude we adopt towards people we personally dislike."You would think that for a father to kill his son for no reason would seem to everyone to be an incontestable objective moral crime, yet the Christian God ordered Abraham to murder Isaac, and Abraham immediately agreed to do so. This unforgivable monster - an infernal father if ever there was one - is celebrated by three world religions, and billions of people, as a moral paragon, someone to be admired and emulated. That demonstrates that either these people have no moral compass and no moral sensibility at all, or all moral "facts" are anything that people want them to be, anything that serves their selfish agenda, which can never be a moral agenda by any conventional definition of morality, i.e. morality can never be that which you do because it suits you, regardless of others. What consideration did Abraham give to Isaac as he held his dagger to his son's throat? From Isaac's perspective, his father was immoral - willing to murder him to prove himself to his deity. Imagine if Isaac had worshiped a different God from Abraham. He would regard Abraham's God as the anti-God, the Devil.The moral con is the biggest con of all. It has been inflicted on the world by the priest-caste, the kingly-caste, and the super-rich elite to stop the people from accepting reason and logic as the means to organize and optimize society. The world rulers have plenty of use for billions of abject slaves on their knees praying to fictitious, invisible gods, and no use for billions of rational and logical men and women who can see through every lie the elite tell them to exploit them.Reason and logic are the means to achieve human liberation. That's why the elite have ensured that reason and logic are never taught, and everyone is instead subjected to insane religious faith and mysticism.Free yourself. Embrace reason and logic. Sapere aude.
