Arguably the most foundational principle in perception research is that our experience of the world goes beyond the retinal image; we perceive the distal environment itself, not the proximal stimulation it causes. Shape may be the paradigm case of such “unconscious inference”: When a coin is rotated in depth, we infer the circular object it truly is, discarding the perspectival ellipse projected on our eyes. But is this really the fate of such perspectival shapes? Or does a tilted coin retain (...) an elliptical appearance even when we know it’s circular? This question has generated heated debate from Locke and Hume to the present; but whereas extant arguments rely primarily on introspection, this problem is also open to empirical test. If tilted coins bear a representational similarity to elliptical objects, then a circular coin should, when rotated, impair search for a distal ellipse. Here, nine experiments demonstrate that this is so, suggesting that perspectival shapes persist in the mind far longer than traditionally assumed. Subjects saw search arrays of three-dimensional “coins,” and simply had to locate a distally elliptical coin. Surprisingly, rotated circular coins slowed search for elliptical targets, even when subjects clearly knew the rotated coins were circular. This pattern arose with static and dynamic cues, couldn’t be explained by strategic responding or unfamiliarity, generalized across shape classes, and occurred even with sustained viewing. Finally, these effects extended beyond artificial displays to real-world objects viewed in naturalistic, full-cue conditions. We conclude that objects have a remarkably persistent dual character: their objective shape “out there,” and their perspectival shape “from here.”. (shrink)

While "moral naturalism" is sometimes used to refer to any approach to metaethics intended to cohere with naturalism in metaphysics more generally, the label is more usually reserved for naturalistic forms of moral realism according to which there are objective moral facts and properties and these moral facts and properties are natural facts and properties. Views of this kind appeal to many as combining the advantages of naturalism and realism but have seemed to (...) many others to do inadequate justice to central dimensions of our practice with our moral concepts. This entry examines some of these concerns and some ways in which moral naturalists have responded to them. It also profiles central aspects of the more particular views of some leading contemporary advocates of moral naturalism. (shrink)

Moral naturalism, as I use the term here, is the view that there are moral facts in the natural world – facts that are both natural and normative – and that moral claims are true or false in virtue of their corresponding or not to these natural facts. Moral naturalists argue that, since moral claims are about natural facts, we can establish the truth about moral claims through empirical investigation. Moral knowledge, on (...) this view, is a form of empirical knowledge.One objection to this metaethical view is that even if moral naturalists are correct in their claims about truth, they cannot answer the question of normativity. Jean Hampton, for instance, argues that it is not enough to explain the conduct's wrongness by showing it to be a property that necessarily supervenes on natural properties. For nothing in this analysis explains the relationship between these properties and us. The question is why should people care about these properties. Christine Korsgaard claims that moral realists take the normative question to be one about truth and knowledge. (shrink)

Naturalist moral realists seem to have landed themselves a raw metaethical deal. Insofar as they identify moral properties in something external to human agents, they struggle to account for the deep practical hold that moral considerations have upon us, and stand accused of failing to take morality seriously as a normative phenomenon. And insofar as their method of identifying which natural properties are the moral ones is fairly permissive, they seem to over-generate admissible moralities, classifying as (...) permissible a range of behaviours that we regard as morally perverse. In this paper, I argue that naturalist moral realists can make progress in addressing both concerns by drawing upon a variety of empirical resources. The former problem is mitigated by paying closer attention to deep-rooted features of human sociality, and by focusing upon the ways in which moral norms themselves build upon affective response. The force of the latter challenge is diminished once we appreciate that the naturalist can distinguish good moral norms from dreadful ones on principled grounds. None of this entails that the naturalist moral realist is home and dry. However, my arguments do suggest that her opponents strongly underestimate the resources at her disposal. (shrink)

The Projectability Challenge states that a metaethical view must explain how ordinary agents can, on the basis of moral experience and reflection, accurately and justifiably apply moral concepts to novel situations. In this paper, we argue for two primary claims. First, paradigm nonnaturalism can satisfactorily answer the projectability challenge. Second, it is unclear whether there is a version of moral naturalism that can satisfactorily answer the challenge. The conclusion we draw is that there is an important (...) respect in which nonnaturalism holds an advantage over its most prominent naturalist rivals. The conclusion is interesting if only because it is widely assumed that naturalism has an easier time handling thorny problems in moral epistemology. We argue that there is at least one such problem of which this assumption is not true. (shrink)

Some versions of moral naturalism are faulted for implausibly denying that moral obligations and prescriptions entail categorical reasons for action. Categorical reasons for action are normative reasons that exist and apply to agents independently of whatever desires they have. I argue that several defenses of moral naturalism against this charge are unsuccessful. To be a tenable meta-ethical theory, moral naturalism must accommodate the proposition that, necessarily, if anyone morally ought to do something, then (...) s/he has a categorical reason to do it. Versions of moral naturalism that deny this claim would, if widely believed, disable some crucial practical uses of moral concepts. In particular, if the existence of normative reasons for action is taken to be dependent on agents’ desires, it would breed profound skepticism about the legitimacy of evaluating others’ actions from a moral point of view. Also, it would raise doubts about whether people ought to correct their own behavior in light of moral considerations. Following Richard Joyce, I take these consequences to indicate that the concept of a categorical reason is a “non-negotiable” part of moral concepts. (shrink)

Moral naturalism is the view that moral properties exist in a manner that fits with our scientific worldview. Might empirical discoveries about the genealogy of moral judgments (that, for example, they issue from an evolved psychological faculty) serve to undermine moral naturalism? One way of undermining moral naturalism is to show that moral properties do not exist at all. The possibility of genealogical considerations supporting this conclusion is examined and found to (...) be weak. Alternatively, might empirical discoveries about the genealogy of moral judgments serve to vindicate some form of moral naturalism? This possibility is also explored and found to be unconvincing.

This paper argues against Boydian synthetic moral naturalism by way of a critical examination at metasemantic issues. I first show that the Boydian metasemantics delivers determinate but wrong reference, building on an analysis by Schroeter and Schroeter. I then propose a diagnosis which says that the problem occurs due to an overly simple way of understanding externalist metasemantics, and that a proper understanding requires us to pay heed to the higher-level constraints set by the speakers’ deferring pattern. That (...) in turn is restricted by what I call reference defeaters, which are essentially some central beliefs held by the speakers and are so called because they have the power to defeat reference of a term to certain things. Applying the notion to moral discourse, I argue that the entrenched is/ought distinction held by the ordinary speakers defeats the reference of the moral predicates to natural properties, that is, synthetic moral naturalism is not true.

A posteriori Moral Naturalism posits a posteriorimoral/naturalistic identities. Versions of this view thatposit necessary identities purport to rely on theKripke/Putnam doctrine of scientific essentialism.Versions that posit only contingent identities requirethat moral terms are non-rigid designators. I argue thatmetaethics does not fall within the scope of scientificessentialism and that moral terms are not non-rigid designators.

In lieu of an abstract, here is a brief excerpt of the content:Hume Studies Volume 27, Number 1, April 2001, pp. 3-83 Moral Skepticism and Moral Naturalism in Hume's Treatise NICHOLAS L. STURGEON Section I I believe that David Hume's well-known remarks on is and ought in his Treatise of Human Nature (T 469-70)1 have been widely misunderstood, and that in consequence so has their relation to his apparent ethical naturalism and to his skepticism about the (...) role of reason in morality. My aim in this paper is to display their connection with these larger issues in Hume's work by placing them in a more illuminating light. Readers may wonder whether there is anything left to say about the passage containing these remarks; they may also share Barry Stroud's suspicion that the vast literature focused on this one paragraph has "given it an importance and point out of all proportion to its actual role in the text of the Treatise."2 But I have some new things to say. I agree, moreover, that many recent discussions, in projecting twentieth-century assumptions onto Hume's text, have accorded this passage the wrong sort of importance: that is part of what I want to correct. But getting clear about what Hume is saying here is, I shall argue, a way of moving familiar and obviously central questions about his views on morality into an unfamiliar but revealing focus. Hume's is-ought thesis is commonly, and I believe correctly, seen as an application of his more general skepticism about the capacity of reason to discover "moral distinctions." But that general skepticism is usually taken, in turn, to conflict with those many passages in which Hume Nicholas L. Sturgeon is Professor of Philosophy, Sage School of Philosophy, Cornell University, Ithaca, NY 14853-3201, USA. e-mail: [email protected] 4 Nicholas L. Sturgeon appears to say, in a reductive and naturalistic vein, that ascriptions of moral virtue and vice simply state certain empirical facts, facts about our own sentiments. My central thesis, however, is that Hume's view that there is a logical gap between is and ought is not merely consistent with his reductive naturalism, but actually depends on it. It is precisely because moral ascriptions state the facts that they do about our sentiments that no ought can be derived from an is and, a bit more generally, that reason is unable to discover moral distinctions. Hume's skepticism about reason in ethics depends, I shall argue, on his reductive ethical naturalism. This is not the usual understanding of Hume's views, and it will require careful explanation and defense. I shall proceed in several stages. My first step, in Section II, will be to argue that Hume's naturalism is at least consistent with his skepticism about reason, and in particular with his remarks about is and ought. I shall show this by focusing on a difficulty often taken to epitomize the conflict between these two strains in his thought: namely, that the paragraph containing these remarks (T 469-70: henceforth, the is-ought paragraph) and the one immediately preceding it (which I shall call the matter -of-fact paragraph (T 468-9)) appear, on their most natural readings, flatly to contradict one another.3 On the most common reading of the is-ought paragraph, it assumes the existence of two classes of statements, «-statements and oM^hr-statements, and declares that no member of the latter class can be derived entirely from members of the former. In the preceding paragraph, however, Hume appears in the guise of an ethical naturalist and subjectivist, and, if we take him at his word, simply equates a moral judgment with one asserting what he himself calls a "matter of fact," albeit a psychological fact about oneself: So that when you pronounce any action or character to be vicious, you mean nothing, but that from the constitution of your nature you have a feeling or sentiment of blame from the contemplation of it. (T 469) But, one supposes, if a moral assessment of an action or character is equivalent in meaning to a description of one's sentiments, then it can be derived from that description, and there...

This paper concerns the relation between two metaethical theses: moral naturalism and moral skepticism. It is important that we distinguish both from a couple of methodological principles with which they might be confused. Let us give the label “Cartesian skepticism” to the method of subjecting to doubt everything for which it is possible to do so—usually by introducing alternative hypotheses that are consistent with all available evidence (e.g., brains in vats). Let us give the label “global (...) class='Hi'>naturalism” to the principle that requires of any item which we admit into our ontology that it “fits” (in some manner or cluster of manners to be specified) with our naturalistic scientific worldview. One might be both a Cartesian skeptic and a global naturalist, if the latter principle is something that has survived the former test procedure. Alternatively, one might have adopted global naturalism for some other reason, while having little patience for the Cartesian method of doubt. Moral naturalism is the metaethical view that moral entities (e.g., properties like goodness and evil) fit within the scientific image of the world. The moral naturalist will probably be a global naturalist, but need not be: It is consistent with allowing non-natural entities into one’s ontology that one happens to think that moral properties are of the natural variety. Moral skepticism denies that moral entities fit within our scientific worldview. One way of denying moral naturalism is to be a moral error theorist: to hold that our moral discourse attempts to make reference to moral properties, but these properties do not exist.1 Another way of denying moral naturalism is to be a noncognitivist: to hold that our moral discourse was never really in the business of referring to moral facts or properties in the first place, and ipso facto such facts or properties are not naturalistic. In this paper, the label “moral skepticism” denotes the disjunction of these two theses. Neither the error theorist nor the noncognitivist must be committed to global naturalism, but usually will be; indeed, this commitment will often be a motivating factor of their metaethical views..

ABSTRACT Moral Naturalism is the view that moral judgments aim at describing moral facts and that these are ordinary garden-variety natural facts. Moral Naturalism has trouble accounting for the intuition that we cannot outsource moral judgments, i.e., we cannot ground a moral conviction that p on the fact that a reliable moral adviser holds that p. There have been, however, several attempts to explain this intuition away or to discredit the intuition (...) pumps that bring it forward. I argue that moral naturalists are not in a position to deny this intuition. Moral Naturalism embodies a conception of the minimal conditions for someone to qualify as capable of making moral judgments; among these conditions is the acknowledgment of the supervenience of the moral on the non-moral; given the naturalist's conception of what it takes for someone to be capable of moral judgment, if we allow agents to outsource their moral judgments we come to situations in which the convictions of moral agents do not comply with the acknowledgment of moral supervenience. The naturalist must, therefore, deny the possibility of moral outsourcing. Moral Naturalism, then, faces the problem of making sense of the ban on moral outsourcing. (shrink)

Moral naturalists are often said to have trouble making sense of inter-communal moral disagreements. The culprit is typically thought to be the naturalist’s metasemantics and its implications for sameness of meaning across communities. The most familiar incarnation of this metasemantic challenge is the Moral Twin Earth argument. We address the challenge from the perspective of analytic naturalism, and argue that making sense of inter-communal moral disagreement creates no special issues for this view.

In this paper, I show how realist moral naturalists can provide an intra-theoretic explanation of the epistemic possibility of wholesale moral error. This is a requirement on metaethical theories that has been recently defended by Akhlaghi (2021). After clarifying Akhlaghi’s argument and responding to Evers’s (2021) recent rebuttal, I argue that even under the assumption that moral facts are grounded in an appropriate subset of natural facts (N-facts), there is still a non-zero probability of wholesale moral (...) error. This is demonstrated by considering three types of epistemically possible scenarios: specifically, it could either be that N-facts do not actually exist, or that N-facts exist in a way that entails wholesale moral error, or that N-facts exist in a non-error theoretic way, but their existence is temporally restricted.

In Book I of Plato’s Republic, Thrasymachus famously maintains that ideas of morality and justice are nothing more than an ideology indoctrinated in “the weaker” to benefit “the stronger.” This is Thrasymachus’s challenge to morality: the thesis that some social arrangements, including some moral norms, are products of ‘false consciousness.’ False consciousness occurs when a dominant social group shapes the beliefs and desires of a subordinate group in such a way that the subordinates act for the benefit of the (...) dominants, but against their own interests. In this paper, I grant that some moral norms emerge or persist because of false consciousness. However, I shall argue that these norms actually have the function of impartially promoting the interests of all persons in their range of application. Even if the actual effect of false consciousness norms is to benefit a powerful class while being harmful and discriminatory toward others, the true function of false consciousness norms is the intended effect that they were designed to have. And the crucial feature of false consciousness norms is that their designers—particularly subordinates—teach, preach, follow, and enforce them with the intention of promoting the mutual interests of everyone to whom the norms apply.

We propose an objective and justifiable ethics that is contingent on the truth of evolutionary theory. We do not argue for the truth of this position, which depends on the empirical question of whether moral functions form a natural class, but for its cogency and possibility. The position we propose combines the advantages of Kantian objectivity with the explanatory and motivational advantages of moral naturalism. It avoids problems with the epistemological inaccessibility of transcendent values, while avoiding the (...) relativism or subjectivism often associated with moral naturalism. Our position emerges out of criticisms of the contemporary sociobiological views of morality found in the writings of Richard Alexander, Michael Ruse, and Robert Richards. (shrink)

Metaethicists of all stripes should read and learn from Richard Joyce's book The Evolution of Morality. This includes moral realists, despite Joyce's own nihilism. Joyce thinks that moral obligations, prohibitions, and the like are myths. But that is just a bit of a rich, broad account of moral attitudes and practices, the bulk of which can comfortably be accepted by realists. In fact, other than nihilism itself, there's only one claim of Joyce's which realists must reject. I (...) argue that that claim ought to be rejected, and reply to Joyce's argument to the contrary. The result is that—aside from nihilism and one rejectable claim—realists are free to take from Joyce whatever they like. (shrink)

In this paper I explore the implications of moral vagueness (viz., the vagueness of moral predicates) for non-naturalist metaethical theories like those recently championed by Shafer-Landau, Parfit, and others. I characterise non-naturalism in terms of its commitment to 7 theses: Cognitivism, Correspondence, Atomism, Objectivism, Supervenience, Non-reductivism, and Rationalism. I start 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. (...) I then argue 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.

The prospects for moral realism and ethical naturalism have been important parts of recent debates within metaethics. As a first approximation, moral realism is the claim that there are facts or truths about moral matters that are objective in the sense that they obtain independently of the moral beliefs or attitudes of appraisers. Ethical naturalism is the claim that moral properties of people, actions, and institutions are natural, rather than occult or supernatural, features (...) of the world. Though these metaethical debates remain unsettled, several people, myself included, have tried to defend the plausibility of both moral realism and ethical naturalism. I, among others, have appealed to recent work in the philosophy of language—in particular, to so-called theories of “direct reference” —to defend ethical naturalism against a variety of semantic worries, including G. E. Moore's “open question argument.” In response to these arguments, critics have expressed doubts about the compatibility of moral realism and direct reference. In this essay, I explain these doubts, and then sketch the beginnings of an answer—but understanding both the doubts and my answer requires some intellectual background. (shrink)

In Kitcher’s ‘pragmatic naturalism’ moral evolution consists in pragmatically motivated moral changes in response to practical difficulties in social life. No moral truths or facts exist that could serve as an ‘external’ measure for moral progress. We propose a psychologically realistic conception of moral objectivity consistent with this pragmatic naturalism yet alive to the familiar sense that moral progress has an objective basis that transcends convention and consensus in moral opinion, even (...) when these are products of serious, extended and collaborative reflection.

To enhance the plausibility of naturalistic moral realism, David Copp develops an argument from epistemic defeaters aiming to show that strongly a priori synthetic moral truths do not exist. In making a case for the non-naturalistic position, I locate Copp’s account within the wider literature on peer disagreement; I identify key points of divergence between Copp’s doctrine and conciliatorist doctrines; I introduce the notion of ‘minimal moral competence’; I contend that some plausible benchmarks for minimal moral (...) competence are grounded in substantive moral considerations; and I discuss two forms of spinelessness that Copp’s moral naturalism could result in.

It is a commonly held view that the existence of moral value somehow depends upon the existence of God. Some proponents of this view take the very strong position that atheism entails that there is no moral value; but most take the weaker position that atheism cannot explain what moral value is, or how it could have come into being. Call the first position Incompatibility, and the second position Inadequacy. In this paper, I will focus on the (...) arguments for Inadequacy. There are two main arguments for this position: the Argument from Arbitrariness and the Screening-Off Argument. I’ll discuss each in turn., and argue that neither is successful. To conclude, I’ll sketch what I think is a promising beginning to a naturalistic account of morality. (shrink)

This paper takes up an important epistemological challenge to the naturalistic moral realist: that her metaphysical commitments are difficult to square with a plausible rationalist view about the epistemology of morality. The paper begins by clarifying and generalizing this challenge. It then illustrates how the generalized challenge can be answered by a form of naturalistic moral realism that I dub joint-carving moral realism. Both my framing of this challenge and my answer advertise the methodological significance of non-fundamental (...) epistemological theorizing, which defends and deploys epistemological claims without adverting to the most fundamental epistemological facts.

My goal in this paper is to show that naturalists cannot reasonably endorse moral realism. My argument will come in two parts. The first part aims to show that any plausible and naturalistically acceptable argument in favor of belief in objective moral properties will appeal in part to simplicity considerations (broadly construed)—and this regardless of whether moral properties are reducible to non-moral properties. The second part argues for the conclusion that appeals to simplicity justify belief in (...) moral properties only if either those properties are not objective or something like theism is true. Thus, if my argument is sound, naturalists can reasonably accept moral realism only if they are prepared to accept something like theism. But, as will become clear, naturalists can reasonably accept theism or something like it only if belief in some such doctrine is justified by the methods of science. For present purposes, I’ll assume (what I think virtually every naturalist will grant) that belief in theism and relevantly similar doctrines is not justified by the methods of science. Thus, I will conclude that naturalists cannot reasonably accept moral realism. (shrink)

In "Freedom and Resentment" P.F. Strawson, famously, advances a strong form of naturalism that aims to discredit kcepticism about moral responsibility by way of approaching these issues through an account of our reactive attitudes. However, even those who follow Strawson's general strategy on this subject accept that his strong naturalist program needs to be substantially modified, if not rejected. One of the most influential and important efforts to revise and reconstruct the Strawsonian program along these lines has been (...) provided by R. Jay Wallace, who presents a "narrower" construal of our reactive attitudes in his own account of what is involved in holding an agent responsible. In this paper I argue that Wallace's narrow construal of responsibility comes at too high a cost and that naturalists of a broadly Strawsonian cast should reject it. Related to this point, I argue that Wallace's narrow conception of responsibility is a product of his effort to construct his account within the confines of "the morality system" (i.e. as described by Bernard Williams) and that this way of construing responsibility leads into series of unnecessary and misleading oppositions. A more plausible middle path, I maintain, can be found between Strawson's excessively strong naturalist program and Wallace's narrow and restrictive view of responsibility. (shrink)

Perhaps the most familiar understanding of “naturalism” derives from Quine, understanding it as a continuity of empirical theories of the world as described through the scientific method. So, it might be surprising that one of the most important naturalistic moral realists, Philippa Foot, rejects standard evolutionary biology in her justly lauded _Natural Goodness_. One of her main reasons for this is the true claim that humans can flourish (eudaimonia) without reproducing, which she claims cannot be squared with evolutionary (...) theory and biology more generally. The present argument concludes that Foot was wrong to reject evolutionary theory as the empirical foundation of naturalized eudaimonist moral realism. This is based on contemporary discussion of _biological function_ and _evolutionary fitness_, from which a definition of “eudaimonia” is constructed. This gives eudaimonist moral realism an empirically respectable foundation. (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)

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)

이 논문의 주된 목적은 듀이의 자연주의적 관점에서 도덕적 경험과 심미적 경험의 연속 성의 의미를 밝히는 것이다. 심미적 경험을 모든 경험의 완결적 국면으로 보는 듀이에 따 르면, 여타의 경험과 마찬가지로 도덕적 경험 또한 심미적 경험이 될 수 있다. 그런데 듀 이는 어떻게 도덕적 경험이 심미적 경험이 될 수 있는지를 구체적으로 해명하지 않았다. 그 결과 듀이의 윤리학은 심미적 경험의 관점에서 이해되기보다 과학적이고 실험적인 방 법 및 그 결과만을 우선시하는 이론으로 오해되는 측면이 있다. 연구자는 듀이가 가능성으 로만 제시한 도덕적 경험과 심미적 경험의 연속성 (...) 논제를 구체적인 맥락에서 조명함으로 써, 듀이의 윤리학이 자연과학적 확실성에 기반한 이론이 아니라 경험의 질적 성장을 위한 방법론이라는 점을 드러내 보일 것이다.

The paper distinguishes three strategies by means of which empirical discoveries about the nature of morality can be used to undermine moral judgements. On the first strategy, moral judgements are shown to be unjustified in virtue of being shown to rest on ignorance or false belief. On the second strategy, moral judgements are shown to be false by being shown to entail claims inconsistent with the relevant empirical discoveries. On the third strategy, moral judgements are shown (...) to be false in virtue of being shown to be unjustified; truth having been defined epistemologically in terms of justification. By interpreting three recent error theoretical arguments in light of these strategies, the paper evaluates the epistemological and metaphysical relevance of empirical discoveries about morality as a naturally evolved phenomenon.

There may be as much philosophical controversy about how to distinguish naturalism from non-naturalism as there is about which view is correct. In spite of this widespread disagreement about the content of naturalism and non-naturalism there is considerable agreement about the status of certain historically influential philosophical accounts as non-naturalist. In particular, there is widespread agreement that G.E. Moore's account of goodness in.

According to moral realists, ethics concerns matters of fact. According to naturalist moral realists, moral facts just are natural facts. In this book, I provide an in-depth analysis of moral naturalism's ontological, epistemological, semantic and psychological foundations.

An increasingly common form of naturalism associated with the study of morality is what might be called “scientific naturalism,” which takes as its subject matter various empirical phenomena associated with talk of “morality” and aims to subject them to scientific inquiry, just like any other empirical phenomena. This is unproblematic when it comes to scientific investigations into the origins of the human capacity for normative guidance or moral emotions, or the neurophysiology associated with moral feeling and (...) behavior, but things get much more complicated when it comes to the project of explaining our moral beliefs. It is, of course, an empirical phenomenon that we hold the moral beliefs we do, so it may seem obvious that this too can be causally explained using scientific tools. But, while there is room for scientific inquiry into causal factors, such as evolutionary influences, that have plausibly helped to shape many moral beliefs to some degree, it is a mistake to assume that our moral beliefs across the board can best be explained through appeal exclusively to scientifically accessible causes. This scientific naturalist exclusivity assumption is in fact deeply problematic, overlooking (or prematurely dismissing) the possibility that at least many of our moral beliefs are best explained through our grasping of good reasons for them – considerations we correctly understand as justifying them, though this is not something that shows up in scientific causal explanations. It is easy to miss this point about the potential role of the appreciation of justification by the believing mind when considering moral judgments simply from the external perspective of an amoral anthropologist, but it becomes clear when taking up the internal perspective of the committed moral agent, as when thinking about why we ourselves believe that human trafficking is wrong. This matters because, while science is invoked by those who purport to provide “debunking explanations” of our moral beliefs across the board (showing them to result simply from causal factors insensitive to any objective moral facts), they are actually relying on the scientific naturalist exclusivity assumption, thus begging the question against their opponents, who hold that we have knowledge of objective morality as a result of grasping good reasons for it. I explore these complexities surrounding the explanation of our moral beliefs and argue that while the picture advocated by debunkers remains a possibility, it is certainly not established by science, and recent arguments purporting to debunk the idea of knowable, objective morality fail.

What should a Quinean naturalist say about moral and mathematical truth? If Quine’s naturalism is understood as the view that we should look to natural science as the ultimate ‘arbiter of truth’, this leads rather quickly to what Huw Price has called ‘placement problems’ of placing moral and mathematical truth in an empirical scientific world-view. Against this understanding of the demands of naturalism, I argue that a proper understanding of the reasons Quine gives for privileging ‘natural (...) science’ as authoritative when it comes to questions of truth and existence also apply to other stable and considered elements of our inherited world-view, including, arguably, our firmly held mathematical and moral beliefs. If so, then the ‘thin’ mathematical and moral realisms of Penelope Maddy and T. M. Scanlon, respectively, are vindicated. We do not need to shoehorn mathematical and moral truths into the pushings and pullings of our empirical scientific world-view; for the busy sailor adrift on Neurath’s boat, mathematical and moral truths already have their place.

One central question of metaethics concerns whether there are any moral facts. I argue that morality as such is characterized by a number of distinctive features, and that metaphysical naturalists should believe that there are moral facts only if there is a plausible naturalistic explanation of the existence of facts which exemplify those features. I survey three prominent (and very different) naturalistic moral theories—the reductive naturalism of Peter Railton, Frank Jackson’s analytic descriptivism, and Christine Korsgaard’s Kantianism—and (...) argue that none of them has the resources to explain the existence of genuine moral facts.

Cultural evolution, producing group‐level adaptations, is more problematic than the cultural evolution of individually confirmable skills, but it probably has occurred. The “conformist transmission,” described by Boyd and Richerson (1985), leads local social units to become homogeneous in anadaptive, as well as adaptive, beliefs. The resulting intragroup homogeneity and inter‐group heterogeneity makes possible a cultural selection of adaptive group ideologies.All archaic urban, division‐of‐labor social organizations had to overcome aspects of human nature produced by biological evolution, due to the predicament of (...) genetic competition among the cooperators. The universal norms found in archaic moral systems are seen as curbs to this human nature, reinforced by beliefs in invisible sanction systems and rewarding and punishing afterlives (as in heaven or reincarnation). Perhaps the ubiquity of lavishly wasteful royal funerals is to be explained as contributing to this function. (shrink)

This essay develops the epistemic challenge to non-naturalist moral realism. While evolutionary considerations do not support the strongest claims made by ‘debunkers’, they do provide the basis for an inductive argument that our moral dispositions and starting beliefs are at best partially reliable. So, we need some method for separating truth from falsity. Many non-naturalists think that rational reflection can play this role. But rational reflection cannot be expected to bring us to truth even from reasonably accurate starting (...) points. Reflection selects views that are coherent and conflict-free, yet there is no reason to think that the non-natural moral truth must be like this. Inasmuch as we seek coherent, conflict-free, ethical viewpoints, that suggests that our goal is not non-natural truth at all. (shrink)

Physicist Sean Carroll has developed a new theory of the fundamental nature of reality, which he calls “Poetic Naturalism,” with the stated goal of developing a theory of what is real that is consistent with the findings of natural science. Carroll claims to prove that morality cannot be seen as objectively true. This essay argues that Carroll's conclusion is not convincing; there is no good reason to reject moral objectivity within a purely naturalistic worldview.
