Matthew Yglesias has just the right deflationary take on the Anthony Flew kerfuffle:
[T]he most noteworthy thing about Flew's neo-Deism is that this is a belief with no cash value. Obviously, the origins of life on earth are somewhat mysterious given our current state of empirical science. Nevertheless, nothing follows from believing that, in some mysterious way, a Higher Power created life as opposed to believing that the origins of life fit into the naturalistic scheme somehow but that how, exactly, it fits in is a bit mysterious. The entire apparent significance of Flew's change of heart rests on the fact that the "God" concept is, in contemporary society, deeply resonant of associations with Christian, Jewish, Islamic, etc. theology. But the stance Flew is advocating actually has nothing whatsoever in common with the world's great religions. Instead, its upshot is, for all intents and purposes, the same as the upshot of atheism. If I decided that Flew was right, I wouldn't start behaving differently in any way, or even need to modify my beliefs about any other subject.
