Abstract

Simon Blackburn’s supervenience argument against moral realism has been widely discussed since its first appearance more than thirty years ago. A number of different suggestions have been made as to how the argument can be countered. In a review of Blackburn’s Spreading the Word, Crispin Wright comments on the argument and rather briefly points out some technical difficulties with it that arise from the formula used in the definition of supervenience. In this paper, I try to show, building on Wright’s criticism and taking a number of new objections into consideration, that the Moorean realist can meet Blackburn’s explanatory charge.
