Abstract

Extract: Maria Baghramian and Annalisa Coliva (henceforth, B&C) have written a superb, compendious book on various kinds of relativism (2019). While they give nuanced and sympathetic reconstructions of these views, it is illuminating to see them show, repeatedly and in detail, how each of these views succumbs to a familiar dilemma: a relativistic view requires that it be possible for two judgers to genuinely disagree with one another, even while their views count as ‘equally valid’. However, it is not possible to make sense of this combination: in each and every case, the view either fails to specify a genuine disagreement, or it fails to make sense of equal validity. Since I completely agree with this type of critique of relativistic views (see Boghossian 2006, 2008), I found it hard to find something to write a critical notice about. However, there is one argument I was not convinced by and that is B&C’s argument against Gilbert Harman’s influential version of moral relativism. Since their discussion of Harman is original and interesting and leads to a number of fundamental philosophical issues, I will devote this notice to a detailed critique of it.
