   Allan Gibbard (2003) has recently proposed a new argument for the supervenience of normative judgements grounded in his fact-prac world apparatus as a representational device for capturing normative judgments. Given that account of the content of normative judgments it will turn out to be necessary that those with moral attitudes are committed to normative judgments which treat descriptively identical items the same for purposes of planning.  This is because the plans themselves must be formulated so as to individuate circumstances of action using “recognitional” concepts.  Thus any two recognitionally identical circumstances will yield the same plan of action. If Gibbard’s reasons for thinking that plans must be formulated in recognitional terms are cogent, this result would allow the theory to explain the relevant phenomenon of supervenience. It does not, however, show that a cognitivist theory might not do just as well on its own terms.
