According to philosophical orthodoxy, the parties to moral or legal disputes genuinely disagree only if their uses of key normative terms in the dispute express the same meaning. Recently, however, this orthodoxy has been challenged. According to an influential alternative view, genuine moral and legal disagreements should be understood as metalinguistic negotiations over which meaning a given term should have. In this paper, we argue that the shared meaning view is motivated by much deeper considerations than its recent critics recognize, and that much would be lost in opting for the explanation of normative disputes as metalinguistic negotiations.
