In this paper, I argue that a realist account of the modality of moral supervenience is superior to a non-cognitivist account. According to the recommended realist account, moral supervenience amounts to strong supervenience where the outer ‘necessary’ is conceptual and the inner metaphysical. It is argued that non-cognitivism faces a critical choice between weak and strong supervenience where both options are implausible on this view. However, non-cognitivism seems to have an important advantage: It can explain why the outer ‘necessary’ is (...) conceptual by reference to the function of moral language to influence behaviour. In the main part of the paper, I argue that realism is able to explain why ‘necessary’ in moral supervenience needs to be understood in the recommended manner by reference to the connection between moral properties and moral reasons. Moreover, I argue that the realist account has other attractive features. In contrast to non-cognitivism, it can unify the normative sphere by being generalizable to other normative notions. In addition, it can be part of an explanation of why moral language can have the function to influence behaviour. (shrink)

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.

Quasi-realist expressivists set themselves the task of developing a metaethical theory that at once captures what they call the “realist-sounding” elements of ordinary moral thought and discourse but is also distinctively antirealist. Its critics have long suspected that the position cannot have what it wants. In this essay, I develop this suspicion. I do so by distinguishing two paradigmatic versions of the view—what I call Thin and Thick expressivism respectively. I contend that there is a metaethical datum regarding our epistemic (...) achievements in the moral domain that presents challenges for each variety of expressivism. Thin expressivism opts not to accommodate and explain this datum but I contend that its rationale for not doing so rests on a suspect methodology. Thick expressivism looks as if it must accommodate and explain this datum but I argue that it is poorly situated to do so. I conclude that we have reason to believe that paradigmatic expressivism cannot have all that it wants. (shrink)

If ethical expressivism is true, then moral judgements are motivational desire-like states and do not robustly represent reality. This gives rise to the problem of how to understand moral error. How can we be mistaken if there is no moral reality to be mistaken about? The standard expressivist explanation of moral doubt is couched in terms of our fear that our judgements may not survive improvements to our epistemic situation. There is a debate between Egan :205–219, 2007), Blackburn :201–213, 2009), (...) Köhler :161–165, 2015) and Ridge :1–21, 2015) on the adequacy of this explanation when it comes to the phenomenon of fundamental moral error. This paper is my contribution to the debate. I argue, contrary to Blackburn and Ridge, that expressivism is committed to some first-order anti-realist sounding claims, and thus quasi-realism fails. If expressivism is true, none of us can coherently believe we might be fundamentally mistaken. However, contrary to Egan and Köhler, I do not think this is bad. Expressivists can still do what motivated the project of quasi-realism in the first place: they can interpret, make sense of, and vindicate ordinary moral discourse. I end by showing it yields some positive results for moral philosophers too – it effectively amounts to a transcendental argument against unhealthy moral scepticism. (shrink)

I argue that standard explanationist solutions to the problem of creeping minimalism are largely on the right track, but they fail to correctly specify the kind of explanation that is relevant to distinguishing realism from quasirealism. Quasirealism should not be distinguished from realism in terms of the explanations it gives of why a normative judgment—a normative sentence or attitude—has the semantic content that it has. Rather, it should be distinguished in terms of the explanations it offers of what the semantic (...) content of a normative judgment is. (shrink)

Expressivists traditionally explain normative supervenience by saying it is a conceptual truth. I argue against this tradition in two steps. First, I show the modal claim that stands in need of explanation has been stated imprecisely. Classic arguments in metaethics for normative supervenience and those that rely on it as a premise presuppose a constraint on the supervenience base that is rarely (if ever) made explicit: the repeatability of the non-normative properties on which the normative supervenes. Non-normative properties are repeatable (...) when it is possible for numerically distinct individuals to share them. Second, I show if the modal truth that stands in need of explanation entails that there are individuals exactly alike in repeatable non-normative respects that cannot normatively differ, then standard expressivist accounts of normative supervenience as a conceptual truth are unsuccessful. Expressivist metasemantics for normative terms, together with constitutive facts about the non-cognitive attitudes essentially involved in normative thought, strongly suggest that repeatable supervenience could not be a conceptual truth. I argue, finally, that although repeatable supervenience bears the marks of a conceptual truth, expressivists should be content to treat it as an ordinary normative truth, and to explain it the same way they explain other normative truths.

I argue that Jonas Olson’s argument from irreducible normativity is not a secure basis for an argument for error theory and that a better basis is provided by the argument from supervenience, which has more bite against non-naturalist moral realism than Olson is willing to allow. I suggest there may be a view which can allow for the existence of irreducibly normative facts while remaining unaffected by the kinds of arguments that work against non-naturalist realism. This view is expressivism. Interestingly, (...) James Dreier has recently suggested that expressivism may not escape these arguments. I very briefly outline possible response strategies for expressivists. I close by discussing Olson’s argument against expressivism. Olson suggests, somewhat surprisingly, that expressivism is a bad fit with a plausible evolutionary explanation of our moral thought. I argue that Olson’s argument does not succeed. (shrink)

Non-naturalism – roughly the view that normative properties and facts are sui generis and incompatible with a purely scientific worldview – faces a difficult challenge with regard to explaining why it is that the normative features of things supervene on their natural features. More specifically: non-naturalists have trouble explaining the necessitation relations, whatever they are, that hold between the natural and the normative. My focus is on Stephanie Leary's recent response to the challenge, which offers an attempted non-naturalism-friendly explanation for (...) the supervenience of the normative on the natural by appealing to hybrid properties, the essences of which link them to both natural and sui generis normative properties in suitable ways. I argue that despite its ingenuity, Leary's solution fails. This is so, I claim, because there are no hybrid properties of the sort that her suggestion appeals to. If non-naturalists are to deal with the supervenience challenge, they will have to find another way of doing so. (shrink)

Nonnaturalist realism is the view that normative properties are unique kind of stance-independent properties. It has been argued that such views fail to explain why two actions that are exactly alike otherwise must also have the same normative properties. Mark Schroeder and Knut Olav Skarsaune have recently suggested that nonnaturalist realists can respond to this supervenience challenge by taking the primary bearers of normative properties to be action kinds. This paper develops their response in two ways. First, it provides additional (...) motivation for the previous claim about the bearers of normative properties by drawing from the work of H. A. Prichard. Second, and more importantly, it formulates a plausible metaphysical framework based on the contemporary trope theory to explain why action kinds would have their second-order properties, including their normative properties, necessarily.

Quasi‐realists are expressivists who say much of what realists say. To avoid making their view indistinguishable from realism, however, they usually stop short of saying everything realists say. Many realists therefore think that something important is missing from quasi‐realism. I argue that quasi‐realists can undermine this thought by defending a version of quasi‐realism that I call super‐quasi‐realism. This version seems indistinguishable from realism, but I argue that this is a mistaken impression that arises because we cannot believe super‐quasi‐realism.

In the 1970s and 1980s, Simon Blackburn published a number of much-discussed works in which he argued that the supervenience of the moral on the natural generates a serious problem for moral realism, a problem which his own brand of moral projectivism can avoid. As we will see below, Blackburn construed moral supervenience in terms of what is known as weak supervenience. Partly in response to Blackburn, a number of philosophers have argued that weak supervenience is too weak to capture (...) the intuitive sense in which the moral supervenes on the natural. Instead, it is argued, we should opt for strong supervenience, and, further, that strong supervenience completely disables Blackburn's argument against moral realism. This idea – that strong supervenience undermines Blackburn's argument – is very common in recent metaethics, and the purpose of the present paper is to develop a challenge to this near-orthodoxy.

If the quasi-realist wants to earn the right to talk like a moral realist, he needs to be able to make sense of moral error. A special form of error—fundamental moral error—is often thought to be u...
