Moral Supervenience

A central metaphysical debate about laws concerns whether they govern or merely summarize. This debate has recently been extended to moral laws, with fresh criticism directed at the Humean position by, inter alia, David Enoch and Daniel Fogal & Olle Risberg. These criticisms have seemed compelling, we think, because a contemporary Humean metaphysics of moral laws has only been offered implicitly or with important metaphysical concessions. Our aim, therefore, is to sketch the first explicitly Humean metaphysics of moral laws, modeled (...) on David Lewis's Best Systems Account. We then employ this framework to rebut the objections from Enoch and Fogal. This paper rescues the Humean position from criticisms that have made it seem untenable, and clarifies the role of moral laws within a version of Humeanism: moral laws unify particular moral facts and guide practical deliberation without being metaphysically fundamental.

In this paper I discuss five meta-ethical challenges to Naturalistic Moral Realism, which includes secular moral codes such as Secular Humanism that, in my view, naturalists need to address to keep their commitment to moral realism from looking like special pleading. The five challenges are as follows: 1. The Ontological Problem (OP): How do such moral principles exist? 2. The Epistemic Problem (EP): How does our moral sense/intuition track such principles? 3. The Influence Problem (IP): What authority does the existence (...) of such principles have to supervene on our behavior? 4. The Axiological Problem (AP): What entities have moral value and deserve moral consideration? 5. Methodological Problem (MP): How do we go about arbitrating between moral claims when they conflict?

Can one be a feminist and a Humean at the same time? That is, can one consistently maintain a feminist politic whilst also endorsing Hume’s Law? Gillian Russell has recently put forward an extended defence of so-called ‘barrier laws’, including Hume’s law: that one cannot ‘get an ought from an is’. Such a barrier law implies a distinction between the normative and the nonnormative, or between facts and values. However, Russell is also a feminist — she, like many contemporary logicians, (...) is committed to feminism in and beyond logic — and it is a widely held truism amongst many feminist scholars that the fact/value distinction is a pernicious dualism and artefact of patriarchal ideology. It seems that these commitments are in tension. This paper will develop this tension, showing that feminists drawn to Humeanism (and vice versa) should be worried about it. The paper will then set out six potential ways to resolve the tension between feminism and Humeanism and will conclude by suggesting that the most attractive position of those surveyed is one that actually involves biting a bullet: giving up on a feminist opposition to dualisms.

There has been a great deal written about normativity in recent years by philosophers, with a range of accounts developed and questions raised. Various normative notions (or seemingly normative notions) have all attracted a great deal of attention, notions such as reason, duty, ought, obligation, value, standard and norm, and the notion of fittingness. We find discussions of normativity, and perhaps the normative itself, in many domains of philosophical enquiry: ethics, aesthetics, epistemology, logic and more. Similarly, many figures from the (...) history of philosophy have their thoughts cast in a normative manner. There has been so much written recently about the very idea of normativity that we need to take stock of where we are and think about how present work might point to future thought. In this introduction I summarize various trends of thought, questions and ideas that philosophers have recently discussed and use these as a platform to speculate as to what directions there might be for future work about normativity. I end by summarizing the chapters in this volume whilst tying them to my previous thoughts. (shrink)

The neo-Humean account of moral principles (NHM) is a theory about the metaphysical status of moral principles. According to NHM, moral principles (in the genetic, non-propositional sense) are entities that supervene upon, and are nothing over and above, the distribution of properties located at the Humean mosaic (the set of fundamental, non-modal, physical properties). In this paper, I do two things. First, I make the case for NHM: NHM explains pure moral principles in a straightforward way while also explaining moral (...) supervenience in a dialectically advantageous way. Secondly, I defend the contingentist aspect of NHM: the properties that figure in the Humean mosaic are governed by a principle of recombination. And the fact that moral properties figure in that mosaic contingently suggests that moral principles are also contingent (i.e. they differ depending on a given world’s distribution of base-properties). This makes NHM susceptible to a normative authority problem, an epistemological problem, a moral luck problem, and a modal miracle problem. I show that NHM can meet these challenges, thus making it superior to other moral contingentist proposals on the market. (shrink)

According to the Divide & Conquer (DC) strategy (Fogal and Risberg 2020) for explaining moral supervenience, the modal covariation between moral and natural properties can be partly explained by appeal to pure moral principles. Bhogal (2022) has recently argued that DC fails. A pure moral principle like Act Utilitarianism (AU) cannot explain moral supervenience because AU is not a difference-maker for moral supervenience. There is nothing special about AU which explains why moral properties supervene on natural properties; other moral principles (...) would also explain moral supervenience. On the other hand, if the proponent of DC appeals to some general feature of pure moral principles (like the fact that they have a “bridge-law” structure) then there is a question of what explains that feature. In this paper I do two things. First, I explore a possible extension of the DC-strategy against Bhogal's objection: I consider whether pure moral principles have the right features to explain moral supervenience by showing how these features follow from plausible assumptions about the underlying metaphysics of moral principles. Secondly, I show how this extended version of the DC-strategy can be used as a novel argument for moral contingentism. (shrink)

In this book, the idea of moral generalism, i.e. morality depends on moral principles, and its arguments are debunked. The author argues that there are no substantive true moral generalizations, and that the existence and provision of such generalizations are not necessary conditions for plausible moral thought, action and education.

Explaining the supervenience of the moral on the natural is, perhaps, the central metaphysical challenge for the non-naturalist. However, Scanlon (2014) and Fogal and Risberg (2020) have developed a strategy which purports to explain supervenience rather simply. Fogal and Risberg call it the 'Divide and Conquer' strategy. The key idea is to postulate explanatory moral principles linking the natural and the moral. The moral principles are metaphysically necessary, so trivially supervene on the natural. All other moral facts are determined by (...) the necessary moral principles and the natural facts, so they supervene on the natural too. I argue that there are two versions of the Divide and Conquer strategy and both fail. The first strategy doesn’t give an adequate explanation of supervenience because it doesn't properly identify what makes a difference to the holding of supervenience. The second perhaps does give an adequate explanation of supervenience, but only by introducing something similarly puzzling that needs explanation. Consequently, non-naturalists need additional metaphysical machinery to develop their view -- just appealing to moral principles or metaphysical laws won't do the job. (shrink)

It is very natural to think that if two people, x and y, are qualitatively identical and have committed qualitatively identical actions, then it cannot be the case that one has committed something wrong whereas the other did not. That is to say, if x and y differ in their moral status, then it must be because x and y are qualitatively different, and not simply because x is identical to x and not identical to y. In this fictional dialogue (...) between Socrates and Cantor involving infinitely many qualitatively identical agents, this assumption is challenged. (shrink)

This article explores the ambivalent relationship of neo-Aristotelian naturalism to ethical supervenience. One of the main proponents of this approach, Michael Thompson, holds a position that leads to a rejection of local ethical supervenience. It is argued that this rejection implicitly undermines a premise held by other prominent neo-Aristotelian naturalists, such as Philippa Foot or Rosalind Hursthouse, who implemented Thompson’s species-relative logic of ethical evaluations into their theories. This premise—that there is a systematic connection between the virtuous life and the (...) benefit of the individual—could be re-established if neo-Aristotelian naturalism abandoned the species-essentialist understanding of life-forms and instead accepted local ethical supervenience as an ethical frame of reference. Although this article derives its problem from the main works of the aforementioned authors, its interest lies not mainly in exegesis, but in the systematic discussion of the logical status and the functionality of the concept of life-form in neo-Aristotelian naturalism. This discussion will be enriched by the inclusion of the logical distinctions and insights from modern philosophical biology. (shrink)

This paper explores connections between theories of morality and theories of properties. It argues that (1) moral realism is in tension with predicate, class and mereological nominalism; (2) moral non-naturalism is incompatible with standard versions of resemblance nominalism, immanent realism and trope theory; and (3) the standard semantic arguments for property realism do not support moral realism. I also raise doubts about trope-theoretic explanations of moral supervenience and argue against one version of the principle that we should accept theories that (...) maintain neutrality. (shrink)

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)

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. (shrink)

This paper explores the connection between two philosophical debates concerning the nature of properties. The first metaethical debate is about whether normative properties are ordinary natural properties or some unique kind of non-natural properties. The second metaphysical debate is about whether properties are sets of objects, transcendent or immanent universals, or sets of tropes. I argue that nominalism, transcendent realism, and immanent realism are not neutral frameworks for the metaethical debate but instead lead to either metaethical naturalism or non-naturalism. We (...) can therefore investigate the metaethical question on its own terms only within the framework of trope theory. (shrink)

I argue for the viability of one neglected way of developing supervenience-based objections to metaethical non-naturalism. This way goes through a principle known as ‘Hume’s Dictum’, according to which there are no necessary connections between distinct existences. I challenge several objections to the Hume’s Dictum-based argument. In the course of doing so, I formulate and motivate modest and precise versions of Hume’s Dictum, illustrate how arguments employing these principles might proceed, and argue that the Hume’s Dictum argument enjoys some advantages (...) relative to other supervenience-based objections to non-naturalism. (shrink)

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)

Expressivism is supposed to have an advantage over moral realism, in that it can explain why it is a conceptual truth that the moral supervenes on the natural, even though the natural does not entail the moral. I develop an analogy between expressivism and a version of theistic moral realism, and argue that this version of theistic moral realism shares any advantage that expressivism might have. It may be that the alleged advantage that expressivism has over moral realism is overstated. (...) Nevertheless, possible analogies between expressivism and theistic moral realism have received very little attention in the past, and are worth considering for their own sake. (shrink)

Moral realism and ethical naturalism are both highly attractive ethical positions but historically they have often been thought to be irreconcilable. Since the late 1980s defenders of Cornell Realism have argued that the two positions can consistently be combined. They make three constitutive claims: (i) Moral properties are natural kind properties that (ii) are identical to (or supervene) on descriptive functional properties, which (iii) causally regulate our use of moral terms. We offer new arguments against the feasibility of Cornell realism (...) and then show that there is a way to be a naturalistic realist that avoids internal inconsistency and uniquely provides for moral normativity.

The death of a person is a tragedy while the explosion of a lifeless galaxy is a mere firework. The moral difference is grounded in the nature of humans: humans have intrinsic worth, a worth that makes their fate really matter. This is the worth proposed as the foundation of ethics. Ethics in the usual sense of right and wrong actions, rights and virtues, and how to live a good life, is founded on something more basic that is not itself (...) about actions, namely the worth of persons. Human moral worth arises from certain properties that distinguish humans from the rest of creation (though some animals share a lesser degree of those properties): rationality, consciousness, the ability to act for reasons, emotional structure and love, individuality. This complex package makes humans the "piece of work" of which Hamlet says, “How noble in reason, how infinite in faculty." The Worth of Persons establishes a foundation for ethics in the equal worth of persons, which makes ethics absolutely objective and immune to relativist attacks because it is based on the metaphysical truth about humans. Endless debate about ethical dilemmas, rules, and principles fails to connect with what is really important ethically, that is, what makes humans matter. (shrink)

Metaethicists often specify non-naturalism in different ways: some take it to be about identity, while others take it to be about grounding. But few directly address the taxonomical question of what the best way to understand non-naturalism is. That’s the task of this paper. This isn’t a merely terminological question about how to use the term “non-naturalism”, but a substantive philosophical one about what metaphysical ideology we need to capture the pre-theoretical concerns of non-naturalists. I argue that, contrary to popular (...) opinion, non-naturalism is best characterized not in terms of identity or grounding, but in terms of essence. First, I lay out some desiderata for a good characterization of non-naturalism: it should (i) speak to and elucidate the non-naturalist’s core pre-theoretical commitments, (ii) render non-naturalism a substantive, local claim about normativity, and (iii) provide the most general characterization of the view possible (iv) in a way that best fits the spirit of paradigm non-naturalist views. I then argue that identity characterizations fail to satisfy the former two desiderata, while grounding characterizations at best don’t satisfy the latter two. So, I propose a new essence characterization of non-naturalism and argue that it does a better job of satisfying all four desiderata. Moreover, I argue that this essence characterization has important implications for both metaethical and metaphysical theorizing. (shrink)

Moral realists often disagree about the nature of moral properties. These properties can be natural (as per naturalistic moral realism) or non-natural. But it is unclear how we should understand the notion of naturalness employed in these discussions. In this paper I propose a novel account of moral naturalness. I suggest that a property F is natural iff F falls within the scope of a natural law. In turn, a law is natural when it figures in a nomic nexus involving (...) the laws of physics. (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)

Ethics normally proceeds by establishing some kind of ground from which norms can be derived for human action. However, no such terra firma is found in Jean-Paul Sartre’s Being and Nothingness, which instead lays down a sedimentary soil consisting of a blend of nothingness and contingency. This paper aims to show how Sartre is able to build an ethical theory from this seemingly groundless mixture, and it proceeds in three sections. Section one aims to disentangle the relation between the for-itself (...) (pour-soi) and the in-itself (en-soi) from antithetical characterizations by placing them in a state of supervenience. Section two works to explain how both the in-itself and the for-itself are not divided ontologically, but are both in the same ontological state, namely, contingency. And in section three, it is argued that Sartre’s ethics reveals that because human beings share the same thrownness with Others in a world, they have to take title for such a world. Within a Sartrean ethics of nothingness, one’s nothingness leads one to the shared nothingness of Others, of which one must take responsibility. (shrink)

A central issue in practical philosophy concerns the relation between moral blameworthiness and normative reasons. As there has been little of direct exchange between the debate on reasons and the debate on blameworthiness, this topic has not received the attention it deserves. In this paper, I consider two notions about blameworthiness and reasons that are fundamental in respective field. The two notions might seem incontrovertible when considered individually, but I argue that they together entail claims that are highly contentious. In (...) particular, I maintain that they entail unreasonable and contradictory claims since the practices of moral blame and rational criticism diverge with regard to three dimensions: justification, response, and function. Thus, we need to give up one of the principal notions. The solutions to this puzzle suggest that the connection between reasons and rationality is weaker than standardly presumed in metaethics. (shrink)

It is commonly assumed that if normative terms are analyzable in descriptive terms, as claimed by analytic reductionists, this provides an easy explanation why normative supervenience would be a conceptual truth. This chapter argues that our knowledge of normative supervenience has two important features this explanation fails to account for: first, the idea that normative properties supervene on descriptive properties seems obvious to us and, secondly, we don’t come to accept this thesis distributively by finding it plausible in each of (...) its particular instances but rather by seeing a pattern that all normative properties must conform to. An alternative is suggested, an expressivist account of normative supervenience that allows us to explain both of these features. The chapter closes by arguing that they require explanation even on the assumption that normative supervenience is not a conceptual truth. This makes the explanation problem concerning our knowledge of normative supervenience more general than previously thought. (shrink)

Unbelievable Errors: An Error Theory about All Normative Judgements, written by Bart Streumer.

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.

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.

Mooreans claim that intrinsic goodness is a conceptual primitive. Fitting-attitude theorists object: they say that goodness should be defined in terms of what it is fitting for us to value. The Moorean view is often considered a relic; the fitting-attitude view is increasingly popular. I think this unfortunate. Though the fitting-attitude analysis is powerful, the Moorean view is still attractive. I dedicate myself to the influential arguments marshaled against Moore’s program, including those advanced by Scanlon, Stratton-Lake and Hooker, and Jacobson; (...) I argue that they do not succeed. (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. (shrink)

The paper describes the problem for robust moral realism of explaining the supervenience of the moral on the non-moral, and examines five objections to the argument: The moral does not supervene on the descriptive, because we may owe different obligations to duplicates. If the supervenience thesis is repaired to block, it becomes trivial and easy to explain. Supervenience is a moral doctrine and should get an explanation from within normative ethics rather than metaethics. Supervenience is a conceptual truth and should (...) be explained by the nature of our concepts rather than by a metaphysical theory. The moral does not supervene on the descriptive, because moral principles are not metaphysically necessary. It concludes that none of these objections is successful, so Robust Realists do have an explanatory debt to worry about. (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)

According to many, that the normative supervenes on the non-normative is a truism of normative discourse. This chapter argues that those committed to more specific moral, aesthetic, and epistemic supervenience theses should also hold : As a matter of conceptual necessity, whenever something has a normative property, it has a base property or collection of base properties that metaphysically necessitates the normative one. The main aim in this chapter is to show that none of the available arguments establish, or indeed (...) the relevant epistemic, aesthetic, and moral supervenience theses. is not a conceptual truth. This has considerable dialectical importance. One interesting upshot is that it affords non-reductivists and non-naturalists a novel way of resisting certain prominent supervenience-based objections to their views, including objections that formulate supervenience as a purely metaphysical thesis. (shrink)

It is widely agreed that normative properties supervene on natural properties. Non-naturalists face a distinctive challenge to explain this relation. Stephanie Leary argues that non-naturalists can meet this explanatory demand by positing the existence of hybrid normative properties. I argue that this proposal does not meet the supervenience challenge.

This chapter argues that the best way for a non-naturalist to explain why the normative supervenes on the natural is to claim that, while there are some _sui generis_ normative properties whose essences cannot be fully specified in non-normative terms and do not specify any non-normative sufficient conditions for their instantiation, there are certain _hybrid_ normative properties whose essences specify both naturalistic sufficient conditions for their own instantiation and sufficient conditions for the instantiation of certain _sui generis_ normative properties. This (...) is the only metaphysical explanation for supervenience on offer, the chapter argues, that can both clearly maintain the pre-theoretical commitments of non-naturalism, and provide a metaphysical explanation not just for supervenience, but for all metaphysical necessities involving natural and normative properties.

Simon Blackburn’s supervenience argument—focusing on the mysterious “ban on mixed worlds”—is still subject to a variety of conflicting interpretations. In this paper, I hope to provide a defense of the argument that clarifies both the argument and the objections it must overcome. Many of the extant objections, I will argue, fail to engage the argument in its true form. And to counter the more compelling objections, it will be necessary to bring in additional argumentation that Blackburn himself does not clearly (...) provide. One important upshot of this discussion is that moral realism is not the only target of the argument: it raises trouble for a variety of metaethical views wed to realist-friendly construals of moral evaluation. Rightly understood, this argument not only survives the prominent responses, but turns out to be more powerful than his critics and Blackburn himself have recognized. (shrink)

The claim that the normative depends on the non-normative is just as entrenched in metanormative theory as the claim that the normative supervenes on the non-normative. It is widely held to be a genuine truism, a conceptual truth that operates as a constraint on competence with normative concepts. Call it the dependence constraint. I argue that this status is unwarranted. While it is true that the normative is dependent, it is not a genuine truism, or a conceptual truth, that it (...) depends on the nonnormative. I argue for the following inadequacy claim: that when we cull all the normative terms from our language, and so the concepts that they stand for, what we will be left with will not necessarily be sufficient to adequately describe, conceptualize or represent what it is that we are supposed to be making normative judgements in virtue of. This has implications for both ascriptive and metaphysical understandings of the dependence constraint, and the potential to radically reshape the dialectic in metanormative theory. (shrink)

This paper is a survey of the supervenience challenge to non-naturalist moral realism. I formulate a version of the challenge, consider the most promising non-naturalist replies to it, and suggest that no fully effective reply has yet been given.

This chapter defends explanatory indispensability arguments for the existence of irreducibly evaluative properties from the so-called ‘supervenience objection’. A structurally similar argument and objection are found in the philosophy of mathematics. It is argued that a response to the supervenience objection is available that is structurally similar to a recent response made in the philosophy of mathematics case. The core claim is that reductive realists in metaethics, like nominalists in philosophy of mathematics, have to take what has been called the (...) ‘hard road’. And in metaethics, like in philosophy of mathematics, there are good reasons to think that this road is not navigable. (shrink)

This article is a short book review of Erik Wielenberg's book Robust Ethics: The Metaphysics and Epistemology of Godless Normative Realism.

In Against Absolute Goodness Richard Kraut aims to show that absolute goodness (or badness) is not reason-giving; it plays no role is justifying or requiring certain attitudes and no role in reasoning about what to do. It passes the buck (it never adds to the weightiness of more specific reasons) and so for practical purposes can be ignored. However, he claims that the notions of ‘a good R’ (e.g. a good play) and ‘good for S’ do justify certain attitudes and (...) play important roles in practical reasoning and do not pass the buck. In this review I critique Kraut’s argument that the notions of ‘a good R’ (e.g. a good play) and ‘good for S’ differ from absolute goodness in these ways. Moreover, I discuss and defend Aristotle’s notion of ‘the fine’ or ‘noble’ (καλόν) and Kant’s notion of unconditional goodness. (shrink)

Drawing on a rich pragmatist tradition, this book offers an account of the different kinds of ‘oughts’, or varieties of normativity, that we are subject to contends that there is no conflict between normativity and the world as science describes it. The authors argue that normative claims aim to evaluate, to urge us to do or not do something, and to tell us how a state of affairs ought to be. These claims articulate forms of action-guidance that are different in (...) kind from descriptive claims, with a wholly distinct practical and expressive character. This account suggests that there are no normative facts, and so nothing that needs any troublesome shoehorning into a scientific account of the world. This work explains that nevertheless, normative claims are constrained by the world, and answerable to reason and argumentation, in a way that makes them truth-apt and objective. (shrink)

Perhaps the actual world does not contain moral properties. But might moral properties be impossible because no world, possible or actual, contains them? Two metaethical theories can be argued to entail just that conclusion; viz., emotivism and error theory. This paper works towards the strongest formulation of the emotivist argument for the impossibility of moral properties, but ultimately rejects it. It then uses the reason why the emotivist argument fails to argue that error-theoretic arguments for the impossibility of moral properties (...) face the same conclusion. Finally the paper argues that these arguments for the possibility of moral properties might have consequences for our thinking about their actuality, regardless of whether we accept emotivism or error theory. (shrink)

Contrary to popular opinion, non-natural realism can explain both why normative properties supervene on descriptive properties, and why this pattern is analytic. The explanation proceeds by positing a subtle polysemy in normative predicates like “good”. Such predicates express slightly different senses when they are applied to particulars (like Florence Nightingale) and to kinds (like altruism). The former sense, “goodPAR”, can be defined in terms of the latter, “goodKIN”, as follows: x is goodPAR iff there is a kind K such that (...) x is a token of K, and K is goodKIN. Now if x and y are descriptively exactly similar, then they are tokens of exactly the same kinds, so x is a token of a goodKIN kind if and only if y is. Therefore, by the definition, x is goodPAR if and only if y is. Supervenience just falls out of the definition of “goodPAR”. (shrink)

This chapter explores the implications of moral vagueness for non-naturalist metaethical theories like those recently championed by Shafer-Landau, Parfit, and others. It characterizes non-naturalism in terms of its commitment to seven theses: Cognitivism, Correspondence, Atomism, Objectivism, Supervenience, Non-reductivism, and Rationalism. It starts by offering a number of reasons for thinking that moral predicates are vague in the same way in which “red,” “tall,” and “heap” are said to be. It then argues that the moral non-naturalist seeking to countenance moral vagueness (...) faces a dilemma: are moral properties vague, or perfectly sharp? On either horn of the dilemma, serious problems arise for some of the central tenets of non-naturalism: vague properties seem to threaten Objectivism, Supervenience, and Non-reductivism; on the other hand, sharp properties raise problems for Supervenience and Rationalism. The difficulties on each horn of the dilemma are real, and while they may not be insuperable, they do, at the very least, drastically limit the things non-naturalists can consistently say about moral properties, facts, and reasons.

Our project in this essay is to showcase nonnaturalistic moral realism’s resources for responding to metaphysical and epistemological objections by taking the view in some new directions. The central thesis we will argue for is that there is a battery of substantive moral propositions that are also nonnaturalistic conceptual truths. We call these propositions the moral fixed points. We will argue that they must find a place in any system of moral norms that applies to beings like us, in worlds (...) similar to our own. By committing themselves to true propositions of these sorts, nonnaturalists can fashion a view that is highly attractive in its own right, and resistant to the most prominent objections that have been pressed against it.
