Moral Epistemology and the supervenience of Ethical concepts

Abstract

Abstract Can there be moral truths, as opposed to truths merely about morals, say about people’s moral attitudes of approval and disapproval? If there can be moral truths, can they be known, or even justifiedly believed? And if there can be moral knowledge or justification, what sorts of evidence can ground it? Would the evidence be, for instance, the same kind that grounds scientific beliefs? Or would it be more like the evidence that grounds mathematical truths, if indeed this is different from the former kind? These questions are fundamental in moral epistemology and will be my subject.
