Abstract

Drawing upon several questions raised in a recent exchange between Putnam and Habermas, this paper exposes Putnam's pragmatist arguments against both moral skepticism and substantive moral realism and examines his realist account of moral objectivity in connection with the notion of truth. We defend that Putnam's conception of moral objectivity can be better understood as a new version of a procedural realism. Furthermore, we discuss an internal tension and some problems that threaten the defense of this kind of moral realism
