 The upshot is that there are both minimalist and realist views about the nature of the explanandum of our question. On the realist view, the challenge is to explain the nature of the property or properties that underlie the objective similarity among normative properties, in virtue of which they are normative, as well as the objective similarities among normative concepts, normative facts, and normative claims. On a minimalist view, the challenge is very different. It is, roughly, to explain what is involved in the predicative use of “normative”. Minimalism leaves open what might be involved. For all that it says, the predicative use of “normative” might involve ascribing a realist property. However, there are alternatives, which, as we will see, are taken up by anti-realist metaethical views such as non-cognitivist expressivism.
