Tristam MacPherson (Daluth) 'Reference Magnets on Normative Twin Earth' to be held in the Lecture Room, 10 Merton Street, Oxford - Seminars in Moral Philosophy webpage


‘Twin Earth’ thought experiments constitute one of the most serious challenges to the semantic program of naturalistic realism in metaethics. This paper develops and defends a response to this challenge that appeals to David Lewis’ theory of reference magnetism: the view that the joints of nature play a distinctive role in determining the reference of our thought and talk. I argue that a moral semantic theory that includes reference magnets is capable of explaining the Twin Earth intuitions in a way that is compatible with a wide range of other commitments in metaphysics and semantics that a normative realist might adopt.
