Abstract

This paper deals with a specific version of metaethical moral relativism, known as “speaker-relativism”. It starts by explaining the position, focussing on the views of two prominent contemporary relativists, Gilbert Harman and James Dreier. Both authors draw an analogy between ethics and modern physics: just as Einstein showed that judgments about time or mass were always relative to a specific frame of reference, Dreier and Harman argue that “absolutist” judgments about moral rightness or wrongness need to be reinterpreted as relative to some particular moral system. They also claim that this analogy allows us to salvage ordinary moral talk. I consider a number of possible objections to their argument, beginning with one, concerning the possibility of moral disagreement, which I think can be successfully answered, and then presenting two criticisms that I take to be more problematic for the relativist. I argue that despite its initial appeal, Harman and Dreier’s suggestion regarding our use of moral language seems to be a source of confusion in certain cases of moral disagreement, and does not appear able to preserve specifically moral normativity – which leads me to conclude that it is best viewed as a variant of an error theory about morality, rather than as the distinct metaethical position it purports to be.
