Bart Streumer has posted Are There Irreducibly Normative Properties? on the Internet. Here is the abstract:
Frank Jackson has argued that, given two plausible claims about supervenience and property identity, there are no irreducibly normative properties. Philosophers who think that there are such properties have made several objections to this argument. In this paper, I argue that all of these objections fail. I conclude that Jackson’s argument shows that there are no irreducibly normative properties.
