“We cannot suppose that an individual’s thinking survives bodily death, since that destroys the organization of the brain and dissipates the energy which utilized the brain tracks. God and immortality, the central dogma of the Christian religion, find no support in science. But we in the West have come to think of them as the irreducible minimum of theology. No doubt people will continue to entertain these beliefs, because they are pleasant, just as it is pleasant to think ourselves virtuous and our enemies wicked. But for my part I cannot see any grounds for either. I do not pretend to be able to prove that there is no God. I equally cannot prove Satan is a fiction. The Christian God may exist, so might the Gods of Olympus, Ancient Egypt or Babylon; but no one of these hypotheses is more probable than any other. They lie outside the region of provable knowledge and there is no reason to consider any of them.”
