 Steps (4)–(6) of this argument are the same as steps (3)–(5) of the low priors argument except that “source physicalism” in step (3) of the low priors argument is replaced by “aesthetic deism” in step (4) of the decisive evidence argument. This makes no difference as far as the inference from step (4) to step (5) is concerned. That inference, like the inferences from steps (1)–(3) to step (4) and from step (5) to step (6), is clearly correct. The key question, then, is whether premises (1), (2), and (3) are all true.
