Many hope that our values, purged of messy human contingency, could aspire to correspond with mind-independent, rationally obligatory, and eternal ethical facts. But if the arguments of this thesis are on the right track, we should reject the search for non-natural and mind-independent moral truths.

There is a well‐known argument against irreducibly normative properties that appeals to the following claim about supervenience: for all possible worlds W and W*, if the instantiation of descriptive properties in W and W* is exactly the same, then the instantiation of normative properties in W and W* is also exactly the same. This claim used to be uncontroversial, but recently several philosophers have challenged it. Do these challenges undermine this argument? I argue that they do not, since the negation (...) of this claim about supervenience has consequences that are much more implausible than the negations of key premises in these challenges. (shrink)

On one way of talking about a traditional metaethical topic, realists accept that some items appear on the list of what exists in the moral or more broadly normative domain of inquiry. They then divide over whether those items are like what science and experience suggest that all other items on the list of what exists across all domains are like – naturalistic and secular. Reductive naturalists answer this further question affirmatively. Why don’t nonnaturalists? I explore the answer that it’s (...) because normative entities are “just too different” in the sense that they are countably different things. However, I argue that this answer rests on the subtle presupposition that the normative domain doesn’t also contain uncountable entities of the sort that analytic metaphysicians call “stuff”. Taking intuitions of difference seriously points the way to a novel form of metaethical reductive naturalism. The key is to identify the stuff that matters. (shrink)

This paper seeks to clarify one of the deepest questions about the source or ground of normativity, while also presenting an essence-based approach to answering it. We call it the ‘Arché Question.’ Though all metanormative theories must address this question, very few realists have explicitly grappled with the challenge it poses; those who have appear to deny any need to give an answer. After critically discussing extant realist responses, this paper outlines an essence-based approach to answering the Arché Question that (...) draws on theoretical resources forged in recent advances in post-modal metaphysics.

A core tenet of metanormative non-naturalism is that genuine or robust normativity—i.e., the kind of normativity that is characteristic of moral requirements, and perhaps also of prudential, epistemic and even aesthetic requirements—is metaphysically special in a way that rules out naturalist analyses or reductions; on the non-naturalist view, the normative is sui generis and metaphysically discontinuous with the natural. Non-naturalists agree, however, that the normative is modally as well as explanatorily dependent on the natural. These two commitments—discontinuity and dependence—at least (...) initially pull in opposite directions, and one of the central challenges to non-naturalism is how to reconcile them. In this paper I spell out the most pressing version of this discontinuity problem, as I propose to call it, and I go on to offer a novel solution. Drawing on the ideology of reasons-firstism, I formulate an account of normative explanation which reconciles the two commitments, and I argue that competing accounts either do not solve the problem or are implausible on independent grounds.

Argues that the path to the good life does not consist in working toward some abstract concept of the good, but rather by ameliorating the problems of the practices and institutions that make up our practical life.

[This paper is available as open access from the publisher.]The conventional wisdom in ethics is that pure moral laws are at least metaphysically necessary. By contrast, Moral Contingentism holds that pure moral laws are metaphysically contingent. This paper raises a normative objection to Moral Contingentism: it is worse equipped than Moral Necessitarianism to account for the normative standing or authority of the pure moral laws to govern the lives of the agents to whom they apply. Since morality is widely taken (...) to have such a standing, failing to account for it would be a significant problem. The objection also shows that the debate about the modal status of moral principles isn’t a debate solely within modal metaphysics, but has implications for topics in moral philosophy. (shrink)

ABSTRACTIn a series of articles, Asbjørn Steglich-Petersen and Nick Zangwill argue that, since propositional attitude ascription judgements do not behave like normative judgements in being subject to a priori normative supervenience and the Because Constraint, PAs cannot be constitutively normative.1 I argue that, for a specific version of normativism, according to which PAs are normative commitments, these arguments fail. To this end, I argue that commitments and obligations should be distinguished. Then, I show that the intuitions allegedly governing all normative (...) judgements do not even purport to hold for commitment-attributing judgements.RÉSUMÉDans une série d'articles, Asbjørn Steglich-Petersen et Nick Zangwill font valoir que, puisque les jugements d'attribution d'attitude propositionnelle ne se comportent pas comme des jugements normatifs en étant soumis à la survenance normative a priori et à la contrainte du Parce que, les AP ne peuvent être constitutivement normatives. Je soutiens que, pour une version spécifique du normativisme, selon laquelle les AP sont des engagements normatifs, ces arguments échouent. À cette fin, je soutiens d'abord que les engagements et les obligations devraient être séparés. Ensuite, je démontre que les intuitions qui régiraient prétendument tous les jugements normatifs ne prétendent même pas s'appliquer aux jugements attributifs d'un engagement. (shrink)

Ethicists struggle to take reductive views seriously. They also have trouble conceiving of some supervenience failures. Understanding why provides further evidence for a kind of hybrid view of normative concept use.

It’s commonly held that particular moral facts are explained by ‘natural’ or ‘descriptive’ facts, though there’s disagreement over how such explanations work. We defend the view that general moral principles also play a role in explaining particular moral facts. More specifically, we argue that this view best makes sense of some intuitive data points, including the supervenience of the moral upon the natural. We consider two alternative accounts of the nature and structure of moral principles—’the nomic view’ and ‘moral platonism’—before (...) considering in what sense such principles obtain of necessity.

[First published 09/2016; substantive revision 02/2021.] Evaluative terms and concepts are often divided into “thin” and “thick”. We don’t evaluate actions and persons merely as good or bad, or right or wrong, but also as kind, courageous, tactful, selfish, boorish, and cruel. The latter evaluative concepts are "descriptively thick": their application somehow involves both evaluation and a substantial amount of non-evaluative description. This article surveys various attempts to answer four fundamental questions about thick terms and concepts. (1) A “combination question”: (...) how exactly do thick terms and concepts relate evaluation and non-evaluative description? (2) A “location question”: is evaluation somehow inherent to thick terms and concepts, such as perhaps an aspect of their meaning, or merely a feature of their use? (3) A “delineation question”: how do thick terms differ from the thin and from other kinds of evaluative terms? (4) Given answers to these questions, what broader philosophical significance and applications might thick concepts have? (shrink)

A common worry regarding normative supervenience theses is that they are easily trivialized unless we somehow restrict the set of descriptive base properties on which the normative properties supervene. The idea is that if all descriptive properties are included in the base, any two individuals that share all their base properties must be the same individual in the same world, from which it follows that they have the same normative properties. We argue that this trivial explanation for unrestricted normative supervenience (...) fails. Moreover, we argue that even if it succeeded, this wouldn’t undermine the explanation challenges associated with normative supervenience. (shrink)

This paper defends views like rule consequentialism by distinguishing between two sorts of ideal world objections. It aims to show that one of those sorts of objections is question-begging. Its success would open up a path forward for such views.

Hume’s Law that one cannot derive an “ought” from an “is” has often been deemed to bear a significance that extends far beyond logic. Repeatedly, it has been invoked as posing a serious threat to views about normativity: naturalism in metaethics and positivism in jurisprudence. Yet in recent years, a puzzling asymmetry has emerged: while the view that Hume’s Law threatens naturalism has largely been abandoned (due mostly to Pigden’s work, see e.g. Pigden 1989), the thought that Hume’s Law is (...) a serious challenge to positivism has only grown in prominence. Our main aim is to establish that Hume’s Law is not a threat to positivism or naturalism. First, we connect extensive, but unfortunately siloed, discussions of this issue. Second, we show that Hume’s Law is not a serious threat to naturalism or positivism, for the gap between logic and such theses is very hard to bridge in a way that would make Hume’s Law able to bear this significance. Finally, we emphasize an implication of our discussion: it undermines one of the main “dialectical tributaries” in jurisprudence (Toh 2018). (shrink)

It has seemed, to many, that there is an important connection between the ways in which some theoretical posits explain our observations, and our reasons for being ontologically committed to those posits. One way to spell out this connection is in terms of what has become known as the explanatory criterion of ontological commitment. This is, roughly, the view that we ought to posit only those entities that are indispensable to our best explanations. Our primary aim is to argue that (...) the moral nonnaturalist places herself in an invidious position if she simply accepts that the nonnatural moral facts that she posits are not explanatory. Instead, we offer the nonnaturalist an alternative strategy for dealing with moral explanations. The strategy is to retain the explanatory criterion of ontological commitment and maintain that moral properties are, in fact, explanatory. The explanations they provide are not causal explanations; instead, moral properties make a non-causal difference to the physical facts. (shrink)

Debunking arguments against both moral and mathematical realism have been pressed, based on the claim that our moral and mathematical beliefs are insensitive to the moral/mathematical facts. In the mathematical case, I argue that the role of Hume’s Principle as a conceptual truth speaks against the debunkers’ claim that it is intelligible to imagine the facts about numbers being otherwise while our evolved responses remain the same. Analogously, I argue, the conceptual supervenience of the moral on the natural speaks presents (...) a difficulty for the debunker’s claim that, had the moral facts been otherwise, our evolved moral beliefs would have remained the same. (shrink)

It is widely held, even among nonnaturalists, that the moral supervenes on the natural. This is to say that for any two metaphysically possible worlds w and w′, and for any entities x in w and y in w′, any isomorphism between x and y that preserves the natural properties preserves the moral properties. In this paper, I put forward a conceivability argument against moral supervenience, assuming non-naturalism. First, I argue that though utilitarianism may be true, and the trolley driver (...) is permitted to kill the one to save the five, there is a conceivable scenario that is just like our world in all natural respects, yet at which deontology is true, and the trolly driver is not permitted to kill the one to save the five. I then argue that in the special case of morality, it is possible to infer from the conceivability of such a scenario to its possibility. It follows that supervenience is false. (shrink)

Moral Supervenience says that there can be no moral difference without a descriptive difference. This has been considered one of the least controversial principles in ethics. Explaining it has been a central desideratum. And yet an increasingly popular metaethical view appears to be incompatible with it. According to Moral Contingency, there are metaphysically contingent pure moral principles helping to ground particular moral facts. On such a view, it looks like there can be a difference in pure moral principles without a (...) descriptive difference. This looks like a moral difference without a descriptive difference. Are those who find both Moral Supervenience and Moral Contingency plausible faced with a difficult choice? Many contingentists think so, but I am here to argue that they are mistaken. The two principles are compatible after all, for differences in pure moral principle entail descriptive differences. (shrink)

There is an alternative to the type of moral standing that hypothetically supervenes on other, base or subvenient, properties. Attributed moral standing results when people who have a naturally selected belief that they are worthy of moral consideration negotiate with others with the aim of being acknowledged as having moral standing and are successful. They could successfully negotiate with people who possessed supervenient moral standing. In a hypothetical evolutionary competition with the latter, they would replace them entirely. The result would (...) be a moral community that excludes animals but that includes human infants. Membership in the moral community ends up being what it would be if moral standing supervened on the property of being human. The supervenience doctrine is also criticized on other grounds. (shrink)

In this paper, I criticize the pairing of irreducible thickness with the traditional view of evaluation which says evaluation is a matter of encoding good or bad in some way. To do this, I first explicate the determination view, which holds that irreducibly thick concepts are to thin concepts as determinates are to determinables. I then show that, even if the determination view did establish irreducible thickness, it would not have proven that the evaluative is well understood as being an (...) instance of the determination relation; in order to do that, the determination view needs to show how the evaluative fit a general analysis of the determination relation. However, when the determination view attempts to fill in the analysis, we get implausible results—so implausible, I claim, that we should see the results as a reductio to the view. To generalize the criticism to any view like the determination view, I show that the same results ensue when we model the evaluative on mereology. Finally, I diagnose the general failure by claiming that the evaluative domain, as conceived by the defender of irreducible thickness, just does not have the structure to secure the tight connection between thick and thin concepts while also carving up our conceptual economy in a plausible way.

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)
