The Irrelevance of Supervenience

Abstract Joseph Raz devotes one section of “The Truth in Particularism” to explaining the irrelevance of supervenience to the debate between generalists and particularists. Really, however, his claim is that supervenience is irrelevant to metaethics in general. If there is a true supervenience thesis, he argues, it is not one that we now have access to; moreover, it is not one that we are ever likely to have access to. Raz’s discussion of supervenience has been largely neglected. The chief aim of this chapter is to bring it to light, for it is an argument that merits serious consideration. The secondary aim is to defend it. First, it reconstructs the argument before responding to objections. These objections concern the explanatory role of the general supervenience thesis, the inconceivability of its falsity, the claim that supervenience is a deep feature of our evaluative discourse, and the claim that supervenience of the evaluative on the nonevaluative must hold because the evaluative is grounded in the nonevaluative. The key move in Raz’s argument against supervenience concerns observations that he makes about ordinary evaluative practice. As they stand, these observations are suggestive but brief; however, these observations, supplemented by considerations about thick evaluation, give Raz the resources to respond to all of the above objections.
