Dawkins On Morality
Richard Dawkins discussing The Old Testament, makes the point that the religious make the same kind of judgments that atheists make when it comes to deciding what moral and ethical standards to adopt. The religious, with blinders on, simply don't see that such judgments don't require faith, but are derived by thinking reasoning humans with no need to appeal to imaginary Gods.
Begin in Genesis with the well-loved story of Noah, derived from the Babylonian myth of Uta-Napisthim and known from the older mythologies of several cultures. The legend of the animals going into the ark two by two is charming, but the moral of the story of Noah is applaing. God took a dim view of humans, so he (with the exception of one family) drowned the lot of them including children and also, for good measure the rest of the (presumably blameless) animals as well.
Of course, irritated theologians will protest that we don't take the book of Genesis literally anymore. But that is my whole point. We pick and choose which bits of scripture to believe, which bits to write off as symbols or allegories. Such picking and choosing is a decision, just as much, or as little, as the atheists decision to follow this moral precept or that was a personal decision, without an absolute foundation. If one of these is 'morality flying by the seat of its pants' so is the other. p.237-238
