Metaethical expressivism faces the perennial objection that its commitment to non-cognitivism about moral judgment renders the view revisionary of our ordinary moral thought. The standard response to this objection is to say that since the expressivist's theoretical commitments about the nature of moral judgment are independent of normative ethics, the view cannot be revisionary of normative ethics. This essay seeks to evaluate the standard response by exploring several senses of independence that expressivism might enjoy from normative ethics. I develop a taxonomy on which, at least by the expressivist's own lights, normative ethics is not dependent on non-cognitivism about moral judgment in a way that might render that claim itself normative ethical. The argument will require us to formulate a theory of moral subject matter according to the expressivist, a matter of independent interest. Although this discussion will essentially vindicate the standard response to the perennial objection, it will also highlight a major limitation thereof. This is that even for the expressivist, the taxonomic independence of non-cognitivism about moral judgment from normative ethics does not guarantee its moral independence from normative ethics; that is, showing that non-cognitivism about moral judgment is not a moral claim is not itself to show that it is not a morally relevant claim. I conclude by arguing that the question of moral dependence, usually discussed under the heading of objectivity, is ultimately first-order moral rather than taxonomic, and so can only be resolved on first-order moral grounds.
