Metaethical Mooreanism and Evolutionary Debunking
In this paper I will apply the Moorean response to external world skepticism to moral skepticism, specifically to the evolutionary debunking argument against morality. I begin, in section 1, with a discussion of Mooreanism. In section 2, I proceed to a discussion of metaethical Mooreanism, which is the view that some moral facts are Moorean facts. In section 3 I apply metaethical Mooreanism to the evolutionary debunking argument against morality. If the arguments of the paper hold up it will turn out that it is no more rational to abandon the existence of moral facts than it is to deny that one knows that one has hands.
