H. Allen Orr and Daniel Dennett are tearing into each other something fierce over at Edge, and it’s all over Orr’s dismissive review of Dawkins’ The God Delusion. It’s a bit splintery and sharp, but the core of Orr’s complaint, I think, is that he’s unimpressed with Dawkins’ ‘Ultimate 747’ argument, which is basically that postulating an immensely complicated being to explain the creation of an immensely complicated universe doesn’t actually explain anything and is self-refuting — if you need an intelligent superbeing to create anything complex, then the superbeing itself is an even greater problem for your explanation.
