An additional problem concerns the plausibility of simply extending disagreement based arguments for relativism about predicates of personal taste over to moral predicates like ‘right’ and ‘good’. As Wedgwood (2019) has suggested, moral disagreements, in a way that is disanalogous to disagreements about what’s tasty, implicate a kind of ‘inexcusable irrationality’ (2019: 97)—at least, if the moral truths that constitute moral principles are a priori knowable. To the extent that there is a difference in inexcusability across the two cases of disagreement, it would be contentious to think that an argument from ‘faultless disagreement’ to relativism in the arena of predicates of personal taste would extend, mutatis mutandis, to an analogous argument in the moral arena.
