“I’m a naturalist, an out-and-out naturalist, a philosophical or metaphysical naturalist, a naturalist about concrete reality. I don’t think anything supernatural or otherwise non-natural exists.
One can’t classify anything as supernatural or non-natural until one has a substantive conception of the natural relative to which something can be classified as non-natural. I do have one. I take it that reality—by which I mean concrete reality, anything that exists in spacetime—is entirely physical. I’m a physicalist naturalist. I don’t believe there’s any non- physical concrete reality. I think metaphysical naturalism is the same thing as physicalism as just defined: the view that concrete reality is entirely physical (I’m putting ethics aside).There are, however, important questions to be raised about what this amounts to. They’re old questions, in fact, but they haven’t received enough attention recently. One result of this is that many—probably most—philosophers who call themselves naturalists are in fact extreme anti-naturalists. They’re false naturalists— noturalists. “
