Moral metasemantic theories explain how our moral thought and talk are about certain properties. Given the connection between what our moral terms are about and which moral claims are true, it might be thought that metasemantic theorising can justify first-order ethical conclusions, thus providing a novel way of doing moral epistemology. In this paper, we spell out one kind of argument from metasemantic theories to normative ethical conclusions, and argue that it fails to transmit justification from premises to conclusion. We (...) give three reasons for this transmission failure, which together pose a serious challenge to such metasemantic arguments. (shrink)

Normative naturalism is primarily a metaphysical doctrine: there are normative facts and properties, and these fall into the class of natural facts and properties. Many objections to naturalism rely on additional assumptions about language or thought, but often without adequate consideration of just how normative properties would have to figure in our thought and talk if naturalism were true. In the first part of the paper, I explain why naturalists needn’t think that normative properties can be represented or ascribed in (...) wholly non-normative terms. If so, certain prominent objections to normative naturalism fail. In the second part, I consider the objection that normative properties are “just too different” from (other) natural properties to themselves be natural properties. I argue that naturalists have no distinctive trouble making sense of thought and talk involving forms of “genuine” or “authoritative” normativity which can drive a non-question-begging form of the objection.

Non-naturalist realists are committed to the belief, famously voiced by Parfit, that if there are no non-natural facts then nothing matters. But it is morally objectionable to conditionalise all our moral commitments on the question of whether there are non-natural facts. Non-natural facts are causally inefficacious, and so make no difference to the world of our experience. And to be a realist about such facts is to hold that they are mind-independent. It is compatible with our experiences that there are (...) no non-natural facts, or that they are very different from what we think. As Nagel says, realism makes scepticism intelligible. So the non-naturalist must hold that you might be wrong that your partner matters, even if you are correct about every natural, causal fact about your history and relationship. But to hold that conditional attitude to your partner would be a moral betrayal. So believing non-naturalist realism involves doing something immoral. (shrink)
