Abstract

Some relativists deny that moral discourse is factual. According to them, our ethical commitments are to be explained by appealing to noncognitive mental states like desires, rather than to beliefs in some independent moral facts. Indeed, the package antirealism (there are no moral properties) & noncognitivism (the source of moral commitments is noncognitive) seems to be implicit in Lewis’s and Harman’s relativism. But to many philosophers this package seems to be unattractive. Our task in this paper is to construe and defend a less committal and hence more attractive version of relativism. Our thesis has two elements. First, we shall present a version of relativism that combines, on the one hand, realism with regard to thick ethical properties, and, on the other, antirealism with regard to thin ethical properties. Secondly, we shall argue that this version of relativism can be defended through the skeptical theory of meaning Kripke attributes to the later Wittgenstein. The paper comprises three parts: the first sketches in very broad lines a version of standard moral relativism. In the second part we construe an alternative version that we call ‘cultural relativism.’ By appealing to the thick-thin distinction, cultural relativists explain what it means to say of forms of life that they are in conflict. In the third part we shall elaborate an argument whose conclusion is that in ranking conflicting ethical outlooks, people make an error, that is, they attribute to these outlooks moral properties that do not exist.
