Abstract

A common contemporary claim is the conjunction of metaphysical naturalism—the idea, roughly, that there is no such person as God or anything at all like God—with the view that our cognitive faculties have come to be by way of the processes to which contemporary evolutionary theory direct our attention. Call this view ‘N&E’. I’ve argued elsewhere that this view is incoherent or self-defeating in that anyone who accepts it has a defeater for R, the proposition that her cognitive faculties are reliable, which then gives her a defeater for any proposition she believes, including, of course, N&E itself. The argument for, in turn, depends essentially on the proposition that P is low or inscrutable. To support, I divided N&E into mutually exclusive and jointly exhaustive subcases, arguing that in each subcase Si, P is low or inscrutable. I won’t repeat this argument here, but I do want to focus on a certain essential aspect of the argument for.
