Moral Nonnaturalism

Many of the arguments for and against robust moral realism parallel arguments for and against theism. In this article, I consider one of the shared challenges: the explanatory challenge. The article begins with a presentation of Harman's formulation of the explanatory challenge as applied to moral realism and theism. I then examine two responses offered by robust moral realists to the explanatory challenge, one by Russ Shafer-Landau and another by David Enoch. Shafer-Landau argues that the moral realist can plausibly respond (...) to the challenge in a way unavailable to theists. I argue that Shafer-Landau's response is implausible as it stands and that once revised, it will apply to theism just as well. I then argue that Enoch's response, to the extent that it is plausible, can be used to defend theism as well. (shrink)

Reductionist forms of moral realism, such as naturalist realism, are often thought immune to epistemological objections that have been raised against nonnaturalist realism in the form of reliability worries or evolutionary debunking arguments. This article establishes that reductionist realist views can only explain the reliability of our moral beliefs at the cost of incurring repugnant first-order conclusions.

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.

This paper considers normative naturalism, understood as the view that (i) normative sentences are descriptive of the way things are, and (ii) their truth/falsity does not require ontology beyond the ontology of the natural world. Assuming (i) for the sake of argument, I here show that (ii) is false not only as applied to ethics, but more generally as applied to practical and epistemic normativity across the board. The argument is a descendant of Moore's Open Question Argument and Hume's Is-Ought (...) Gap. It goes roughly as follows: to ensure that natural ontology suffices for normative truth, there must be semantically grounded entailments from the natural truths to the normative truths. There are none. So natural ontology does not suffice for normative truth. (shrink)

Taking Morality Seriously is David Enoch’s book-length defense of meta-ethical and meta-normative non-naturalist realism. After describing Enoch’s position and outlining the argumentative strategy of the book, we engage in a critical discussion of what we take to be particularly problematic central passages. We focus on Enoch’s two original positive arguments for non-naturalist realism, one argument building on first order moral implications of different meta-ethical positions, the other attending to the rational commitment to normative facts inherent in practical deliberation. We also (...) pay special attention to Enoch’s handling of two types of objections to non-naturalist realism, objections having to do with the possibility of moral knowledge and with moral disagreement. (shrink)

This book is a systematic and constructive treatment of a number of traditional issues at the foundation of ethics, the possibility and nature of moral knowledge, the relationship between the moral point of view and a scientific or naturalistic world view, the nature of moral value and obligation, and the role of morality in a person's rational life plan. In striking contrast to many traditional authors and to other recent writers in the field, David Brink offers an integrated defense of (...) the objectivity of ethics. (shrink)

Are non-natural properties worth caring about? I consider two (related) objections to metaethical non-naturalism. According to the "intelligibility" objection, it would be positively unintelligible to care about non-natural properties that float free from the causal fabric of the cosmos. According to the "ethical idlers" objection, there is no compelling motivation to posit non-natural normative properties because the natural properties suffice to provide us with reasons. In both cases, I argue, the objection stems from misunderstanding the role that non-natural properties play (...) in the non-naturalist's understanding of normativity. The role of non-natural properties is not to be responded to, but to mark which natural properties it is correct for us to respond to in certain ways. (shrink)

G. E. Moore famously argued on the basis of semantic intuitions that moral properties are not reducible to natural properties, and therefore that moral predicates refer to nonnatural properties. This clearly represents a version of “moral realism,” but it is a testament to the strength of naturalist intuitions in contemporary philosophical debate that, insofar as one accepts Moore’s arguments, this is typically seen as a boon for antirealists rather than realists. For many philosophers worry that putative nonnatural properties would be (...) too metaphysically and epistemologically queer to be admissible into our ontology. These philosophers conclude that if moral properties cannot be understood as natural properties, then it is more reasonable to abandon commitment to moral properties than to follow Moore into nonnaturalism. -/- In this dialectical milieu, three positions have become popular. Naturalists argue that Moorean arguments are bunk; moral properties can be understood as natural properties. Constructivists argue that Moore was right that moral properties cannot be understood as objective natural properties—that is, the properties that are logically independent of the attitudes of human agents—however, quasi‐objective moral properties can be constructed out of the attitudes of human agents. And noncognitivists argue that moral predicates are nonreferential, and so the best understanding of moral discourse is one which does not construe it as committed to the existence of moral properties. -/- Russ Shafer‐Landau’s new book is distinctive in that it argues against each of these three popular positions while developing and defending a contemporary nonnaturalist version of moral realism.

In "Mathematical Truth", Paul Benacerraf articulated an epistemological problem for mathematical realism. His formulation of the problem relied on a causal theory of knowledge which is now widely rejected. But it is generally agreed that Benacerraf was onto a genuine problem for mathematical realism nevertheless. Hartry Field describes it as the problem of explaining the reliability of our mathematical beliefs, realistically construed. In this paper, I argue that the Benacerraf Problem cannot be made out. There simply is no intelligible problem (...) that satisfies all of the constraints which have been placed on the Benacerraf Problem. The point generalizes to all arguments with the structure of the Benacerraf Problem aimed at realism about a domain meeting certain conditions. Such arguments include so-called "Evolutionary Debunking Arguments" aimed at moral realism. I conclude with some suggestions about the relationship between the Benacerraf Problem and the Gettier Problem. (shrink)

David Enoch has recently proposed that the deliberative indispensability of irreducibly normative facts suffices to support their inclusion in our ontology, even if they are not necessary for the explanation of any observable phenomena. He challenges dissenters to point to a relevant asymmetry between explanation and deliberation that shows why explanatory indispensability, but not deliberative indispensability, is a legitimate guide to ontology. In this paper, I aim to do just that. Given that an entity figures in the actual explanation of (...) some phenomenon, it is not an open question whether that entity exists. Thus, if you can manage to find actual explanations, you can find answers to ontological questions. In contrast, even if some entity is indispensable to deliberation, it still might not exist. For example, even if some form of libertarian free will is deliberatively indispensable, we still might not have libertarian free will. So even if you manage to discover the indispensable commitments of deliberation, there is still more work to do to get to the bottom of things. That additional work is explanatory work, and so deliberative indispensability is not an independent guide to what there is. (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.

According to some contemporary nonnaturalists about normativity , normative facts exist in an ontologically non-committing sense. These nonnaturalists face an explanatory burden. They must explain their claim that normative facts exist in such a sense. I identify criteria for an adequate explanation, and extract five distinct candidate explanations from the writings of these authors . I assess each. None is both informative and recognizable as a version of contemporary nonnaturalism. In light of this, I assess the best options for proponents (...) of this view. (shrink)

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.

Divine Command Theories (DCTs) comes in several different forms but at their core all of these theories claims that certain moral statuses (most typically the status of being obligatory) exist in virtue of the fact that God has commanded them to exist. Several authors argue that this core version of the DCT is vulnerable to an epistemological objection. According to this objection, DCT is deficient because certain groups of moral agents lack epistemic access to God’s commands. But there is confusion (...) as to the precise nature and significance of this objection, and critiques of its key premises. In this article I try to clear up this confusion and address these critiques. I do so in three ways. First, I offer a simplified general version of the objection. Second, I address the leading criticisms of the premises of this objection, focusing in particular on the role of moral risk/uncertainty in our understanding of God’s commands. And third, I outline four possible interpretations of the argument, each with a differing degree of significance for the proponent of the DCT. (shrink)

The traditional conception of response-dependence isinadequate because it cannot account for all intuitivecases of response-dependence. In particular, it is unableto account for the response-dependence of (aesthetic, moral, epistemic ...) values. I therefore propose tosupplement the traditional conception with an alternativeone. My claim is that only a combination of the twoconceptions is able to account for all intuitivecases of response-dependence.

Jesse Prinz develops a naturalistic metaethical theory with which he purports to sidestep ‘Hume's law’ by demonstrating how, on his theory, in describing what our moral beliefs commit us to we can determine what our moral obligations are. I aim to show that Prinz does not deliver on his prescriptive promise – he does not bridge the is–ought gap in any meaningful way. Given that Prinz goes on to argue that (1) his moral psychology highlights fundamental shortcomings in ‘traditional’ normative (...) ethical theories, (2) that moral progress is possible, despite the relativistic implications of his own position, and (3) that this undermining of the is–ought gap should hold true on any naturalistic metaethical theory, the extent to which his project succeeds becomes significant.

Normative realists tend to consider evolutionary debunking arguments as posing epistemological challenges to their view. By understanding Sharon Street’s ‘Darwinian dilemma’ argument in this way, they have overlooked and left unanswered her unique scientific challenge to normative realism. This paper counters Street’s scientific challenge and shows that normative realism is compatible with an evolutionary view of human evaluative judgment. After presenting several problems that her adaptive link account of evaluative judgments faces, I outline and defend an evolutionary byproduct perspective on (...) evaluative judgment. I then argue that a consideration of levels of analysis in biological–behavioral explanation suggests that the realist who adopts the byproduct perspective I outline is not at a prima facie disadvantage to the normative anti-realist on grounds of parsimony. This perspective, I suggest, can enable normative realists to answer evolutionary challenges to their view. (shrink)

In 1971, Simon Blackburn worked out an argument against moral realism appealing to the supervenience of the moral realm on the natural realm.1 He has since revised the argument, in part to take account of objections,2 but the basic structure remains intact. While commentators3 seem to agree that the argument is not successful, they have not agreed upon what goes wrong. I believe this is because no attempt has been made to see what happens when Blackburn's argument is addressed to (...) particular varieties of moral realism. As I see it, we must look to these various brands if we want to understand just where the concept of supervenience can be usefully employed. (shrink)

The distribution of moral properties supervenes on the distribution of natural properties, and this provides a puzzle for non-naturalism: what could explain supervenience if moral properties are not natural properties? Enoch claims moral principles explain supervenience. But this solution is incomplete without an account of what moral principles and properties are, and what relation holds between them. This paper begins to develop such an account by exploring analogous issues for Realism about Laws of nature in philosophy of science. Appealing to (...) Mumford’s Central Dilemma for Realism about Laws, I argue that for moral principles to explain supervenience, moral properties must be ontologically dependent on the principles. I suggest that moral properties are relations between moral principles and natural properties. I also explore what it would take to adapt this explanation to a pluralistic theory of morality. Contributory reasons avoid the Cartwright Problem for Laws in a way component forces cannot. (shrink)

I argue that relativists about evaluative language face some of the same objections as non-naturalists in ethics. If these objections have force, there is reason to doubt the existence of relative evaluative states of affairs. In they do not exist, then relativism leads to an error theory. This is unattractive, as the position was specifically designed to preserve the truth of many evaluative claims.

Jonas Olson defends a moral error theory in (2014). I will first argue that Olson is not justified in believing the error theory as opposed to moral nonnaturalism in his own opinion. I will then argue that Olson is not justified in believing the error theory as opposed to moral contextualism either (although the latter is not a matter of his own opinion).

Sharon Street argues that realism about epistemic normativity is false. Realists believe there are truths about epistemic reasons that hold independently of the agent’s attitudes. Street argues by dilemma. Either the realist accepts a certain account of the nature of belief, or she does not. If she does, then she cannot consistently accept realism. If she does not, then she has no scientifically credible explanation of the fact that our epistemic behaviours or beliefs about epistemic reasons align with independent normative (...) truths. I argue that neither horn is very sharp for realists about epistemic normativity. (shrink)

Terence Cuneo and Russ Shafer-Landau have recently proposed a new version of moral nonnaturalism, according to which there are nonnatural moral concepts and truths but no nonnatural moral facts. This view entails that moral error theorists are conceptually deficient. We explain why moral error theorists are not conceptually deficient. We then argue that this explanation reveals what is wrong with Cuneo and Shafer-Landau’s view.

In "Two sorts of Naturalism" John McDowell is sketching his own sort of naturalism in ethics as an alternative to "bald naturalism". In this paper I distinguish materialist, idealist and absolute conceptions of nature and of naturalism in order to provide a framework for a clearer understanding of what McDowell’s own naturalism amounts to. I argue that nothing short of an absolute naturalism will do for a number of McDowell's own purposes, but that it is far from obvious that this (...) is his position. If he directly denies that it is, he seems to be left with some rather awkward choices. (shrink)

This essay explains for a general philosophical audience the central issues and strategies in the contemporary moral realism debate. It critically surveys the contribution of some recent scholarship, representing expressivist and pragmatist nondescriptivism, subjectivist and nonsubjectivist naturalism, nonnaturalism and error theory. Four different faces of ‘ moral realism ’ are distinguished: semantic, ontological, metaphysical, and normative. The debate is presented as taking shape under dialectical pressure from the demands of capturing the moral appearances and reconciling morality with our understanding of (...) the mind and world.

_Arguing about Metaethics_ collects together some of the most exciting contemporary work in metaethics in one handy volume. In it, many of the most influential philosophers in the field discuss key questions in metaethics: Do moral properties exist? If they do, how do they fit into the world as science conceives it? If they don’t exist, then how should we understand moral thought and language? What is the relation between moral judgement and motivation? As well as these questions, this volume (...) discusses a wide range of issues including moral objectivity, truth and moral judgements, moral psychology, thick evaluative concepts and moral relativism. The editors provide lucid introductions to each of the eleven themed sections in which they show how the debate lies and outline the arguments of the papers. _Arguing about Metaethics_ is an ideal resource text for students at upper undergraduate or postgraduate level.

Against non-analytic naturalism and quietist realism, I defend a robust form of non-naturalism. The argument proceeds as follows: In the face of extensional underdetermination, quietist realism cannot non-question-beggingly respond to alternative accounts that offer formally identical but substantively different interpretations of what reasons are. They face what we might call the reasons appropriation problem. In light of this problem, quietists ought to abandon their view in favor of robust realism. By permitting substantive metaphysical claims we can then argue, based on (...) reasonhood being a relation, that reasonhood is an abstract universal. If reasonhood is an abstract universal, then we can non-question-beggingly assert that the counting in favor of relation is a general kind or genus. This poses a dilemma for non-analytic naturalists: either they need to give the same reductive analysis for epistemic and practical reasons, or they can give a different analyses by treating epistemic and practical reasons as a species of the larger genus. However, the former looks extensionally implausible epistemic reasons are not desire-based and the latter entails that the reduction, via a violation of irreflexivity, fails to ground reasonhood. Naturalistic reductions of the normative, accordingly, face a damning dilemma. We should, in the face of this argument, thus accept a robust form of non-naturalist realism. (shrink)

There is a substantial literature on evolutionary debunking arguments (EDAs) in metaethics. According to these arguments, evolutionary explanations of our moral beliefs pose a significant problem for moral realism, specifically by committing the realist to an unattractive pessimism about the prospects of our having moral knowledge. In this paper, I argue that EDAs exploit an equivocation between two distinct readings of their central claim. One is plausibly true but has no epistemic relevance, and the other would have epistemic consequences for (...) realism, but is false. If I'm right, this undermines attempts to use evolutionary explanations to debunk belief in other domains too. (shrink)

Virtually everyone takes the moral supervenience thesis to be a basic conceptual truth about morality. As a result, if a metaethical theory has difficulties respecting or adequately explaining the supervenience relationship it is deemed to be in big trouble. However, the moral supervenience thesis is a not a conceptual truth (though it may be true) and as such it is not a problem if a metaethical theory cannot respect or explain it.

Metaethical non-naturalists maintain that normative or evaluative properties cannot be reduced to, or otherwise explained in terms of, natural properties. They thus have difficulty explaining what these irreducibly normative properties are supposed to be, other than by saying what they are not. I offer a partial, positive characterization of irreducible normativity in naturalistic terms. At a first pass, it is this: that to attribute a normative property to something is necessarily to commend or condemn that thing, due to the nature (...) of the property attributed. This theory characterizes normativity in terms of the natural phenomenon of performing certain familiar speech acts. The hypothesis does other explanatory work as well: it provides for an account of the "queerness" of normative properties, one superior to other accounts; it explains why metaethical reductionism is bound to fail, in a way friendly to non-naturalism (as opposed to non-cognitivism); and it can help deflect arguments against non-naturalism from the "essential practicality" of normativity.

An important and widely-endorsed argument for moral realism is based on alleged parallels between that doctrine and epistemic realism -- roughly the view that there are genuine epistemic facts, facts such as that it is reasonable to believe that astrology is false. I argue for an important disanalogy between moral and epistemic facts. Epistemic facts, but not moral facts, are plausibly identifiable with mere descriptive facts about the world. This is because, whereas the much-discussed moral open-question argument is compelling, the (...) little-discussed epistemic open-question argument is not. This paper is a critical notice of Terence Cuneo's The Normative Web: An Argument for Moral Realism (Oxford University Press, 2007). (shrink)

There have been times in the history of ethical theory, especially in this century, when moral realism was down, but it was never out. The appeal of this doctrine for many moral philosophers is apparently so strong that there are always supporters in its corner who seek to resuscitate the view. The attraction is obvious: moral realism purports to provide a precious philosophical good, viz., objectivity and all that this involves, including right answers to moral questions, and the possibility of (...) knowing those answers. In the last decade, moral realism has re-entered the philosophical ring in powerful-looking naturalistic form. ln this paper we provide a dialectical overview: we situate the new wave position itself, and also our objections to it, in the context of the evolving program of philosophical naturalism in 20th century analytic philosophy. We seek to show that although this new contender might initially look like championship material, it succumbs to punches surprisingly similar to those that knocked out the old-fashioned versions of naturalist moral realism.

Sharon Street’s 2006 article “A Darwinian Dilemma for Realist Theories of Value” challenges the epistemological pretensions of the moral realist, of the nonnaturalist in particular. Given that “Evolutionary forces have played a tremendous role in shaping the content of human evaluative attitudes” – why should one suppose such attitudes and concomitant beliefs would track an independent moral reality? Especially since, on a nonnaturalist view, moral truth is causally inert. I abstract a logical skeleton of Street’s argument and, with its aid, (...) focus on problematic assumptions regarding the (a)causality of moral truth. It emerges that there are acquired causal powers that compensate for the intrinsic impotence of moral truth, as well as two distinct levels at which truth-tracking might occur. I argue that while evolution’s selective forces do not track moral truth, that does not imply individual organisms could not have evolved that capability. -/- . (shrink)

Robust Realists think that there are irreducible, non-natural, and mind-independent moral properties. Quasi -Realists and Relaxed Realists think the same, but interpret these commitments differently. Robust Realists interpret them as metaphysical commitments, to be defended by metaphysical argument. Quasi -Realists and Relaxed Realists say that they can only be interpreted as moral commitments. These theories thus pose a serious threat to Robust Realism, for they apparently undermine the very possibility of articulating the robust metaphysical commitments of this theory. I clarify (...) and respond to this threat, showing that there is in fact space to develop and defend a robust moral ontology. (shrink)
