This paper raises an objection to two important arguments for reductive ethical naturalism. Reductive ethical naturalism is the view that ethical properties reduce to the properties countenanced by the natural and social sciences. The main arguments for reductionism in the literature hold that ethical properties reduce to natural properties by supervening on them, either because supervenience is alleged to guarantee identity via mutual entailment, or because non-reductive supervenience relations render the supervenient (...) properties superfluous. After carefully characterizing naturalism and reductionism, we will present, explain, and raise objections against each of the main reductionist arguments: that supervenience does not support the claim that ethical properties and their subvenient natural properties are mutually entailing; that reductive views undermine the claim that ethical properties yield resemblance; and that supervenience does not entail that non-descriptive ethical properties are superfluous in the most fundamental sense.

Many philosophers insist that moral facts or properties play no role in explaining (non-normative) natural phenomena. The problem of moral explanation has raised metaphysical, semantic and epistemic challenges to contemporary moral realism. In my dissertation, I attempt to vindicate the explanatory efficacy of moral properties, while at the same time respecting the autonomy and normativity of morality. In doing so, I will advocate a sort of non-reductive ethical naturalism, according to which moral properties are natural properties (in (...) the sense that they are open to empirical investigation), and yet remain irreducible to non-normative natural properties, such as psychological, biological, and sociological properties. More specifically, I develop a form of moral functionalism to vindicate moral explanation. Moral functionalism understands moral properties as second-order, functional properties, the natures of which are characterized in terms of functional roles. My version of moral functionalism has two particular features. First, it is a form of a posteriori moral functionalism. The moral theory used to characterize the functional roles of moral properties can only be discovered by appeal to empirical investigation (for this reason, my a posteriori version of moral functionalism is a sort of ethical naturalism). Second, it is a holistic version of moral functionalism. The functional role of a moral property cannot be identified solely in terms of non-normative properties; rather, it essentially involves a network of connections to both non-normative and normative properties (for this reason, my holistic version of moral functionalism is a sort of ethical anti-reductionism). It is important to note that the question of whether moral properties have explanatory power bears on the question of what explanation or explanatoriness is. In my dissertation, I attempt to show that my vindication of moral explanation presupposes a plausible account of explanation. Obviously I cannot discuss all theories of explanation; my dissertation will rather focus on two influential accounts of explanation: the causalist model and the unificationist model. Then I argue that moral properties understood as functional properties of the kind I have described can do causal-explanatory work and play a distinctive unifying role. (shrink)

The contemporary debate on the metaphysical side of metaethics is dominated by two paradigms—reductive naturalism and primitivist non- naturalism. It is argued here that these are both extreme views. In principle, it should be possible for there to be a host of intermediate views between these two extremes. In fact, most of the views that were taken on these metaphysical questions by philosophers of ancient and medieval times differed from both reductive naturalism and primitivist non- (...) class='Hi'>naturalism. However, the metaphysical views of these past philosophers cannot easily be endorsed today. This is because our conception of the natural world has changed from that of these premodern thinkers, because of the development of modern natural science. Nonetheless, it is still possible to make sense of intermediate positions, lying between the two extremes of reductive naturalism and primitivist non- naturalism. These intermediate positions are prima facie promising, and deserve careful consideration from contemporary metaethicists. (shrink)

It is common in metaethics today to draw a distinction between “naturalist” and “non-naturalist” versions of moral realism, where the former view maintains that moral properties are natural properties, while the latter view maintains that they are non-natural properties instead. The nature of the disagreement here can be understood in different ways, but the most common way is to understand it as a metaphysical disagreement. In particular, the disagreement here is about the reducibility of moral properties, where the “naturalists” maintain (...) that moral properties are in some way reducible to the lower-level natural properties on which they supervene, while the “non-naturalists” maintain that moral properties are sui generis and robustly irreducible. In this paper I present a novel version of realist ethical naturalism—a view that I call Emergentist Ethical Naturalism—that reveals this common way of understanding the distinction between naturalism and non-naturalism to be flawed by combining a commitment to ethical naturalism with a commitment to the sui generis and robustly irreducible nature of moral properties that typically defines non-naturalism. Then, after presenting the theory and addressing a few worries that one might have about it, I show how it offers some novel, emergence-based responses to the various supervenience challenges that plague moral realism and thereby gives the ethical naturalist a robustly non-reductive option for dealing with these challenges.

It is widely accepted that the ethical supervenes on the natural, where this is roughly the claim that it is impossible for two circumstances to be identical in all natural respects, but different in their ethical respects. This chapter refines and defends the traditional thought that this fact poses a significant challenge to ethical non-naturalism, a view on which ethical properties are fundamentally different in kind from natural properties. The challenge can be encapsulated in three (...) core claims which the chapter defends: that a defensible non-naturalism is committed to the supervenience of the ethical, that this commits the non-naturalist to a brute necessary connection between properties of distinct kinds, and that commitment to such brute connections counts against the non-naturalist’s view. Each of these claims has recently been challenged. Against Nicholas Sturgeon’s recent doubts about the dialectical force of supervenience, this chapter defends a supervenience thesis as deserving to be common ground among ethical realists. It is then argued that attempts to explain supervenience on behalf of the non-naturalist either fail as explanations, generate near-identical explanatory burdens elsewhere, or appeal to commitments that are inconsistent with core motivations for non-naturalism. The chapter concludes that, suitably refined, the traditional argument against nonnaturalism from supervenience is alive and well. (shrink)

This article engages with the philosophical reflections of the French historian of science Hélène Metzger (1886–1944) in order to develop a vocabulary for understanding the rise of non-reductive Continental naturalism in the contemporary humanities. The bibliography of current naturalist approaches in the arts and the human sciences is still in the making, but it is altogether clear that the trend is not scientist or historicist or relativist. This epistemological diagnosis refers us to Metzger, who found herself surrounded with (...) the logical positivism of the Wiener Kreis, on the one hand, and the historicism of her French colleagues, on the other, as well as with the infiltration of the history of science by a chronological empiricism. In this article I will take the most recent book of Vicki Kirby – Quantum Anthropologies: Life at Large from 2011 – as an exemplary case of non-reductive Continental naturalist scholarship in the humanities today and by reading it through the concepts of Metzger, I will demonstrate how this type of research leads to refreshing insights in what constitutes positive humanities knowledge and what is the role of the a priori in the field.

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.

Gallagher [2019] defends a form of naturalised phenomenology based on a non-classical view of science. A central component of this argument involves an analogy between phenomenology and quantum-mechanics: Gallagher suggests that both require us to give up key components of a classical view of the natural world. Here, I try to clarify this analogy and consider two associated problems. The first problem concerns the concept of subjectivity and its different roles in physics and phenomenology, and the second concerns the concept (...) of complementarity in quantum mechanics. I argue that complementarity is poorly suited to the integrative view of science that Gallagher ultimately wishes to defend. Instead, a better model of integration can be found in examples of multiscale modelling, which is widespread in science, including classical physics. Gallagher is right to reject an overly narrow view of naturalism, but we do not need to consider the peculiarities of quantum mechanics to find inspiration for a broader view. (shrink)

Shaun Gallagher argues that we need a new philosophy of nature that accommodates the insights of existential phenomenology. On his view existential phenomenology needs a philosophy of nature that is holistic, relational, and non-reductionist. I argue that his reasoning is based on a misunderstanding of the difference between the manifest image and the scientific image. The reasons why we should prefer a non-reductionist philosophy of nature are internal to the historical development of the scientific image itself. We have good reasons (...) for preferring enactivism over cognitivism as a research program for the cognitive sciences, but compatibility with the manifest image is not one of those reasons.

This paper examines the status of naturalism in the philosophies of Edmund Husserl and John Dewey. Despite the many points of overlap and agreement between Husserl’s and Dewey’s philosophical projects, there remains one glaring difference, namely, the place and status of naturalism in their approaches. For Husserl, naturalism is an enemy to be vanquished. For Dewey, naturalism is the only method that can put philosophy back in touch with the concerns of human beings. This paper will (...) demonstrate the remarkable similarities between Husserl’s and Dewey’s thought before contending that Dewey’s “naturalistic humanism” offers a conception of naturalism which is compatible with Husserlian phenomenology. Furthermore, reading these two philosophers together, this paper argues, can point the way forward to a naturalism which avoids the dismissal of the contributions made by knowing subjects carried out by dominant contemporary strains of reductive naturalism.

In this paper we investigate some important trends in contemporary naturalist aesthetics in relation to two decisive issues. Firstly, it is important to explicitly clarify what kind of naturalism is at stake within the debate, more specifically whether an account of the topic involves forms of physical reductionism, emergentism, and/or continuistic views of art and culture with nature. Secondly, we argue that it is necessary to define what conception of art is assumed as paradigmatic: whether this conception deals with (...) basically autonomist approaches to art, assuming aesthetic experience to coincide with the disinterested contemplation of formal features, independently of cognitive, practical, and ethical implications, or whether the arts are considered an enhancement of the features of human expe- rience and developments of other human behaviours. The second part of the paper will investigate some recent developments in current neuroaesthetics and fresh enactivist proposals in the aesthetic field which display a tendency toward a non-reductive naturalism, views of the arts as continuous with other modes of behav- iour and more conscious attitudes about the risks of scientism within scientific in- vestigations. Generally speaking, we espouse an idea of culture as the natural development of human organic experience that involves new emerging properties depending on the re-organization of already existing natural resources and favour continuistic and emergentist views as more suited to dealing with specific prob- lems in the field of the arts and as better responding to the criticism of irrelevancy directed against the latter, compared to reductive naturalist approaches.

Donald Davidson has emphasized the importance of what he calls “triangulation” for clarifying the conditions that make thought possible. Various critics have questioned whether this triangular causal interaction between two individuals and a shared environment can provide necessary conditions for the emergence of thought. I argue that these critical responses all suffer from a lack of appreciation for the way triangulation is responsive to the philosophical commitments of Davidson's naturalism. This reply to Davidson's critics helps clarify several metaphilosophical issues (...) concerning the overall significance of this use of triangulation. I illustrate how the network of commitments that make up Davidson's conception of non‐reductive naturalism inform the respective problems and issues that triangulation is introduced to address. This then serves as an example of the way metaphilosophical considerations are useful in clarifying the status of a respective philosophical position and for understanding the philosophical debates surrounding it.

This is an essay on McDowell’s naturalism. It is, pace some commentators, argued that McDowell’s naturalism does not end up in any strange metaphysical positions in the philosophy of mind, because second nature non-reductively supervenes on first nature and have causal powers.

This chapter discusses fundamental problems and prospects for ethical naturalism. Section 1 explains what is meant by “ethical naturalism” and surveys different versions of the view. Section 2 discusses the central philosophical challenge to ethical naturalism, viz., the “Normativity Objection.” Section 3 offers a battery of responses to it on behalf of the ethical naturalist. Section 4 explores a promising and novel approach to ethical naturalism, viz., a moral nativist theory that (...) that combines a Chomskian approach to moral competence with a structuralist metaphysics.

Ethical non-naturalists posit a sui generis realm of moral and evaluative properties, while ethical naturalists identify moral and evaluative properties with natural or descriptive properties. First, I explore the standard arguments in favor of an ethical non-naturalist account of goodness, specifically the open-question argument. Then, I examine Philippa Foot’s criticism of the open-question argument and her alternative neo-Aristotelian theory of goodness. Foot’s account, I argue, is vulnerable to a revised version of the open-question argument. Finally, I suggest (...) two ways that Foot can escape the revised open-question argument: Either via a classical naturalist account, inspired by Thomas Aquinas, that identifies goodness with the fulfillment of a thing’s function, or by characterizing her account as a version of non-reductive naturalism akin to non-reductive physicalism in philosophy of mind. In either case, I argue that Foot’s neo-Aristotelian naturalism is preferable to ethical non-naturalism concerning the property of goodness. (shrink)

Ethical naturalism is narrowly construed as the doctrine that there are moral properties and facts, at least some of which are natural properties and facts. Perhaps owing to its having faced, early on, intuitively forceful objections by eliminativists and non-naturalists, ethical naturalism has only recently become a central player in the debates about the status of moral properties and facts which have occupied philosophers over the last century. It has now become a driving force in those (...) debates, one with sufficient resources to challenge not only eliminativism, especially in its various non-cognitivist forms, but also the most sophisticated versions of non-naturalism. This volume brings together twelve new essays which make it clear that, in light of recent developments in analytic philosophy and the social sciences, there are novel grounds for reassessing the doctrines at stake in these debates.

Non-reductive moral realism is the view that there are moral properties which cannot be reduced to natural properties. If moral properties exist, it is plausible that they strongly supervene on non-moral properties- more specifically, on mental, social, and biological properties. There may also be good reasons for thinking that moral properties are irreducible. However, strong supervenience and irreducibility seem incompatible. Strong supervenience entails that there is an enormous number of modal truths (specifically, truths about exactly which non-moral properties necessitate (...) which moral properties); and all these modal truths must be explained. If these modal truths can all be explained, then it must be a fundamental truth about the essence of each moral property that the moral property is necessarily equivalent to some property that can be specified purely in mental, social and biological terms; and this fundamental truth appears to be a reduction of the moral property in question. The best way to resist this argument is by resorting to the claim that mental and social properties are not, strictly speaking, natural properties, but are instead properties that can only be analysed in partly normative terms. Acceptance of that claim is the price of non-reductive moral realism. (shrink)

Normative theory, in various idioms, has grown wary of questions of ontology-social and otherwise. Thus modern debates in ethics have tended to take place at some distance from (for example) debates in social theory. One arguable casualty of this has been due consideration of relational factors (between agents and the social structures they inhabit) in the interrogation of ethical values. Part 1 of this paper addresses some examples of this tendency, and some of the philosophical assumptions which might underlie (...) it. Parts 2 and 3 discuss two issues of growing prominence-disability, and environmental concern-due attention to which, I argue, highlights strong reasons why severing ethics from social ontology is neither possible nor desirable. I conclude by recommending a qualified ethical naturalism as a promising candidate through which, non-reductively, to reunite these two areas of theoretical focus. (shrink)

The ethical naturalist asks us to take seriously the idea that practical norms are a species of natural norms, such that moral goodness is a kind of natural goodness. The ethical naturalist has not demonstrated, however, how it is possible for a power of reason to be governed by natural norms, because her own attempts to do this have led her into a dilemma. If she takes the first horn and stresses that ethical naturalism provides objective, (...) natural norms of the species, then she fails to show how such norms are practical, or operative from a deliberative point of view. If she takes the second horn and stresses that ethical naturalism yields a picture of knowledge of human life that is practical because it comes through virtuous dispositions of intellect and will, then she fails to have an account of how it is knowledge of facts about a life form, potentially accessible to a non-human knower. In this paper, I argue that one potential resolution to this dilemma can be found in the writings of Thomas Aquinas. On a broadly Thomist account of practical reason, the first principles of practical reason are our common human ends or goods, which are constitutive of a good human life. The work of practical reason on this naturalistic account is twofold: to conceive and order these ends into some general conception of how to live, and to apply this general conception to the particular situations of one’s life in order to realize one’s vision of the good life, here and now.

Contributing to the naturalistic virtue ethics tradition, Natural Citizens applies recent work in the life sciences to develop a form of ethical naturalism that aspires to be non-reductive yet empirically responsible.

John McDowell has argued that for human needs to matter in practical deliberation, we must have already acquired the full range of character traits that are imparted by an ethical upbringing. Since our upbringings can diverge considerably, his argument makes trouble for any Aristotelian ethical naturalism that wants to support a single set of moral virtues. I argue here that there is a story to be told about the normal course of human life according to which it (...) is no coincidence that there is agreement on the virtues. Because we are creatures who arrive at personhood only by learning from others in a relation of dependency, we cannot help but see ourselves as creatures for whom non-instrumental rationality is the norm. Those who train others in personhood must view the trainee's interests as having a value independent of their interests and must imbue the trainee with a sense of that value. Extending and preserving the sense of self-worth that we must acquire if we are to acquire personhood requires we see ourselves as creatures who need something like the virtues. (shrink)

It is difficult to wander far in contemporary metaphysics without bumping into talk of possible worlds. And, reference to possible worlds is not confined to metaphysics. It can be found in contemporary epistemology and ethics, and has even made its way into linguistics and decision theory. What are those possible worlds, the entities to which theorists in these disciplines all appeal? Some have hoped that a theory of possible worlds can be used to reduce modality to non-modal terms. This paper (...) sets reductive theories aside, and articulates and applies a framework for evaluating non-reductive theories of possible worlds. I argue that, if we abjure reduction, we should aim for a theory of possible worlds that is user-friendly. I then outline four leading contemporary theories and consider objections to each. My conclusions are negative: every theory we discuss fails to be user-friendly in some significant respect. (shrink)

There are many versions of naturalism as an overall position, and there are several significant and influential kinds of naturalism in ethics. The latter views may or may not be realist, and, if realist, may or may not be reductive in one or another sense. The antirealist versions include the noncognitivist view that moral claims do not ascribe genuine properties and, unlike assertions of fact, are not strictly speaking true or false. Which of these views, if any, (...) are harmonious with theism, particularly the monotheistic view that God is omniscient, omnipotent, and omnibenevolent? More broadly, which, if any, are a good basis for ethical reflection in the field of religion, conceived broadly as including nontheistic religions? One would think that, whether or not divine directives determine our obligations, the very existence of God would guarantee that there is a real distinction between right and wrong–or anyway that there are normatively authoritative standards of conduct, as there may be even in nontheistic religions. This essay will clarify naturalism in ethics, identify some major options for theologically oriented ethics, and sketch an ethical view that might capture many of the best elements in both perspectives.

Thus ethical theory has been involved in a double controversy, the general controversy between naturalism and supernaturalism, and a more special one between naturalism, intuitionism, and non-cognitivism. These two debates have been variously mingled. Naturalists in the one sense have not always been naturalists in the other. Some naturalists in the broad sense have also been naturalists in the narrower, but some of them have been intuitionists, and many of them, especially recently, have been non-cognitivists. Again, supernaturalists (...) have sometimes been intuitionists, sometimes non-cognitivists, and sometimes naturalists. (shrink)

Why do agent-relative reasons have authority over us, reflective creatures? Reductive accounts base the normativity of agent-relative reasons on agent-neutral considerations like ‘having parents caring especially for their own children serves best the interests of all children’. Such accounts, however, beg the question about the source of normativity of agent-relative ways of reason-giving. In this paper, I argue for a non-reductive account of the reflective necessity of agent-relative concerns. Such an account will reveal an important structural complexity of (...) practical reasoning in general. Christine Korsgaard relates the rational binding force of practical reasons to the various identities or self-conceptions under which we value ourselves. The problem is that it is not clear why such self-conceptions would necessitate us rationally, given the fact that most of our identities are simply given. Perhaps, Harry Frankfurt is right in arguing that we are not only necessitated by reason, but also, and predominantly by what we love. I argue, however, that “the necessities of love” (in Frankfurt’s phrase) are not to be separated from, but should be seen as belonging to the necessities of reason. Our loves, concerns and related identities provide for a specific and important structure to practical reflection. They function on the background of reasoning, having a specific default role: they would lose their character as concerns, if there was a need for them to be cited on the foreground of deliberation or if there was a need to justify them. This does not mean that our deep concerns cannot be scrutinised. They can only be scrutinised in an indirect way, however, which explains their role in grounding the normativity of agent-relative reasons. It appears that this account can provide for a viable interpretation of Korsgaard’s argument about the foundational role of practical identities. (shrink)

This paper discusses three topics in contemporary British ethical philosophy: naturalisms, moral reasons, and virtue. Most contemporary philosophers agree that 'ethics is natural' - in Section 1 I examine the different senses that can be given to this idea, from reductive naturalism to supernaturalism, seeking to show the problems some face and the problems others solve. Drawing on the work of John McDowell in particular, I conclude that an anti-supernatural non-reductive naturalism plausibly sets the limits (...) on what we can do in ethics. Moral reasons are widely discussed - in Section 2 I describe some of the criteria that used to distinguish moral practical reasons, and note possibilities and problems. Drawing on the work of Elizabeth Anscombe in particular, I suggest that an inclusive, minimalist account of moral reasons may be most fruitful. There has been a revival of philosophical interest in virtue ethics, which I take to be linked to the emergence of non-reductive naturalisms - in Section 3 I describe three points where virtue ethics has an especially significant contribution to make: learning, motivational self-sufficiency, and the question of whether virtues can be reasons. The naturalism of Section 1 constrains the accounts of moral reasons considered in Section 2, and depends upon an account of virtue as learned second nature, discussed in Section 3. (shrink)

The paper presents a positive argument for a version of metaphysically light ethical non-naturalism from the nature of mental states such as desires. It uses as its premise the time-honoured, and recently rediscovered, doctrine of the guise of the good, whereby it is essential to desire that the object of desire be conceived as good or as normatively favoured under some description. The argument is that if the guise of the good is a correct theory of desire, then (...) a certain version of non-naturalism is better placed than other meta-ethical views to make sense of it. First I define ethical non-naturalism and the guise of the good, providing also an initial defence of the latter. Then I briefly survey some historical precedents and proceed to the argument. For each major meta-ethical view I consider I offer reasons why combining them with the guise of the good leads to consequences that are or should be unwelcome by the guise of the good. At the end of this elimination process a form of relatively metaphysically light non-naturalism will emerge as the view that best fits with the guise of the good. (shrink)

Early Daoism, as articulated in the Daodejing and the Zhuangzi, indirectly addresses environmental issues by intimating a non-reductive naturalistic ethics calling on humans to be open and responsive to the specificities and interconnections of the world and environment to which they belong. "Dao" is not a substantial immanent or transcendent entity but the lived enactment of the intrinsic worth of the "myriad things" and the natural world occurring through how humans address and are addressed by them. Early Daoism potentially (...) corrects both anthropocentrism and biocentrism in environmental ethics by disclosing the things themselves in the context of the selfcultivation of life. Given increasing environmental devastation and the dominance of views, practices, and institutions reducing nature to a background and/or raw material for human activity, this "ethics of encounter" discloses the life of things as inexhaustibly more than human projects and constructs, extending ethical recognition and responsibility beyond social relations and the social self.

Ethical realists hold that our ethical concepts, thoughts, and claims are in the business of representing ethical reality, by representing evaluative or normative properties and facts as aspects of reality, and that such representations are at least sometimes accurate. Non-naturalist realists add the further claim that ethical properties and facts are ultimately non-natural, though they are nonetheless worldly. My aim is threefold: to elucidate the sort of representation involved in ethical evaluation on realist views; to (...) clarify what exactly is represented and how non-naturalism comes into the picture for non-naturalists; and to defend worldly non-naturalism against some objections. The first question addressed is how we should model evaluation on any realist view, which should in turn guide the identification of which properties and facts are credibly regarded as ‘evaluative’ ones. Then the question is: what role might non-natural properties and facts play, and how are they related to what is represented in ethical evaluation? Once that is clear, we will be in a position to answer certain objections to non-naturalist realism from Jackson, Gibbard, Bedke, and Dreier. I argue that the objections all mischaracterize the role played by non-natural properties and facts on plausible versions of non-naturalist realism. (shrink)

At the intersection of meta-ethics and philosophy of science, Nicholas Sturgeon’s “Moral Explanation” ([1985] 1988), Richard Boyd’s “How to be a Moral Realist” (1988), and David Brink’s Moral Realism and the Foundations of Ethics (1989) inaugurated a sustained argument for the claim that moral kinds like right action and virtuous agent are scientifically investigable natural kinds. The corresponding position is called “non-reductive ethical naturalism,” or “NEN.” Ethical nonnaturalists, by contrast, argue that moral kinds are genuine and (...) objective, but not natural. This dissertation is largely a challenge to non-reductive ethical naturalism from the viewpoint of ethical nonnaturalism. An introduction, four fairly independent chapters, and a conclusion comprise this dissertation. The introduction (chapter one) situates and summarizes the arguments in the four chapters that immediately follow, and the concluding chapter (chapter six) describes future work related to the arguments in this dissertation. I now turn to chapters two through five. In chapter two, I shore up what I believe are weakness in Derek Parfit’s Triviality Objection to reductive ethical naturalism and then present a challenge to the NEN theorist, which, I argue, the NEN theorist must but ultimately cannot meet. The challenge is to sketch an empirical experiment whereby we can adjudicate between competing moral hypotheses. I explain in terms of experimental design and evaluation why the challenge cannot be met. Chapters three and four focus on the semantics and reference relations of kind terms. In chapter three, I defend the Causal Externalist (CE) theory of semantics and reference against an objection distilled from two articles by Åsa Marie Wikforss. The objection is that CE implies a paradox, escape from which forces the CE theorist upon the horns of a dilemma. I show how the CE theorist can avoid the dilemma by allowing that the intensions of some artificial-kind terms (e.g., ‘jade’) are not given by descriptions associated with the terms. One consequence of this move, however, is that it casts doubt upon the coherence of the claim that moral-kind terms (e.g., ‘morally required action’) are natural-kind terms. In chapter four, I defend Terence Horgan and Mark Timmons’s Moral-Twin Earth argument from three critical responses put forward in recent paper by David Merli. NEN theorists claim that CE can account for the semantics and reference of moral-kind terms. As per Horgan and Timmons (H&T), however, our responses to the Moral-Twin Earth thought experiment give us reason to doubt the NEN theorists’ claim. Against H&T’s argument, however, Merli presents three independent, critical responses, and in this chapter I defend H&T’s argument in a way that is friendly to the ethical nonnaturalist. One upshot is, I contend, that the ethical nonnaturalist can and indeed should co-opt H&T’s argument for his own use. In chapter five, I return to kinds themselves, specifically those in biology. I first point out that ethical nonnaturalism appeals to a metaphysical thesis about nonnatural value, which need not be limited to the moral domain. Then, I argue that biological naturalism alone cannot give a satisfying realist account of biological kinds like HEART and NEURON. Finally, I show that by conjoining the concept of Cummins functions as recently defended by Paul Davies, a thesis about nonnatural value, and Ned Block’s Disney Principle regarding structural properties, the nonnaturalist, unlike the naturalist, can offer a satisfying realist account of biological kinds.

The aim of this article is to draw a sketch of an ontology for Realist Non-Naturalist Cognitivists. A distinction is made between moral property-universals and moral property-particulars. It is argued, first, that moral property-universals have the same ontological status as non-moral property-universals; second, that moral property-universals have many instances in the spatio-temporal world; third that these moral property-instances or -particulars have the same ontological status as non-moral property-particulars.

David Papineau's model of scientific reduction, contrary to his intent, appears to enable a naturalist realist account of the primitive normativity involved in a biological adaptation's being “for” this or that (say the eye's being for seeing). By disabling the crucial anti‐naturalist arguments against any such reduction, his model would support a cogni‐tivist semantics for normative claims like “The heart is for pumping blood, and defective if it doesn't.” No moral claim would follow, certainly. Nonetheless, by thus “pressing from below” (...) we may learn something about moral normativity. For instance, suppose non‐cognitivists like Mackie are right that the semantics of normative claims should be “unified”: if the semantics of moral claims is non‐cognitivist, so too is that of all normative claims. Then, assuming that a naturalist reduction does yield a sound cognitivist account of the primitive normativity, it would follow that our semantics of moral claims is cognitivist as well. (shrink)

It was something of a dogma for much of the twentieth century that one cannot validly derive an ought from an is. More generally, it was held that non-normative propositions do not entail normative propositions. Call this thesis about the relation between the natural and the normative Natural-Normative Autonomy. The denial of Autonomy involves the entanglement of the natural with the normative. Naturalism entails entanglement—in fact it entails the most extreme form of entanglement—but entanglement does not entail naturalism. (...) In a ground-breaking paper “The autonomy of ethics” Arthur Prior constructed some intriguing counterexamples to Autonomy. While his counterexamples have convinced few, there is little agreement on what is wrong with them. I present a new analysis of Autonomy, one which is grounded in a general and independently plausible account of subject matters. While Prior’s arguments do establish shallow natural-normative entanglement, this is a consequence of simple logical relationships that hold between just about any two subject matters. It has nothing special to do with the logical structure of normativity or its relation to the natural. Prior’s arguments leave the fundamental idea behind natural-normative Autonomy intact. I offer a new argument for deep entanglement. I show that in any framework adequate for dealing with the natural and the normative spheres, a purely natural proposition entails a purely normative proposition, and vice-versa. But this is no threat to non-naturalist moral realism. In fact it helps ameliorate the excesses of an extreme non-naturalism, delivering a more palatable and plausible position. (shrink)

David Papineau’s model of scientific reduction, contrary to his intent, appears to enable a naturalist realist account of the primitive normativity involved in a biological adaptation’s being “for” this or that (say the eye’s being for seeing). By disabling the crucial anti-naturalist arguments against any such reduction, his model would support a cognitivist semantics for normative claims like “The heart is for pumping blood, and defective if it doesn’t.” No moral claim would follow, certainly. Nonetheless, by thus “pressing from below” (...) we may learn something about moral normativity. For instance, suppose non-cognitivists like Mackie are right that the semantics of normative claims should be “unified”: if the semantics of moral claims is non-cognitivist, so too is that of all normative claims. Then, assuming that a naturalist reduction does yield a sound cognitivist account of the primitive normativity, it would follow that our semantics of moral claims is cognitivist as well. (shrink)

Metaethical realists disagree about the nature of normative properties. Naturalists think that they are ordinary natural properties: causally efficacious, a posteriori knowable, and usable in the best explanations of natural and social sciences. Non-naturalist realists, in contrast, argue that they are sui generis: causally inert, a priori knowable and not a part of the subject matter of sciences. It has been assumed so far that naturalists can explain causally how the normative predicates manage to refer to normative properties, whereas non-naturalists (...) are unable to provide equally satisfactory metasemantic explanations. This article first describes how the previous non-naturalist accounts of reference fail to tell us how the normative predicates could have come to refer to the non-natural properties rather than to the natural ones. I will then use the so-called qua-problem to show how the causal theories of reference of naturalists also fail to fix the reference of normative predicates to unique natural properties. Finally, I will suggest that, just as naturalists need to rely on the non-causal mechanism of reference magnetism to solve the previous problem, non-naturalists, too, can rely on the very same idea to respond to the pressing metasemantic challenges that they face concerning reference.
