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)

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.

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)

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)

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)

Moral realism faces a well known genealogical debunking challenge. I argue that the moral realist’s best response may involve abandoning metaphysical naturalism in favor of some form of axiarchism—the view, very roughly, that the natural world is “ordered to the good.” Axiarchism comes in both theistic and non-theistic forms, but all forms agree that the natural world exists and has certain basic features because it is good for it to exist and have those features. I argue that (...) theistic and non-theistic forms of axiarchism are better positioned than metaphysical naturalism to avoid two commitments that a moral realist should seek to avoid: that the correctness of our moral beliefs is a major coincidence, and that there is a complete explanation of our moral beliefs that does not mention any moral truths.

This chapter discusses epistemic objections to non-naturalist moral realism. The goal of the chapter is to determine which objections are pressing and which objections can safely be dismissed. The chapter examines five families of objections: (i) one involving necessary conditions on knowledge, (ii) one involving the idea that the causal history of our moral beliefs reflects the significant impact of irrelevant influences, (iii) one relying on the idea that moral truths do not play a role (...) in explaining our moral beliefs, (iv) one involving the claim that if moral realism is true then our moral beliefs are unlikely to be reliable, and (v) one involving the claim that moral realism is incompatible with there being a plausible explanation of our reliability about morality. The overall conclusion of the chapter is that the final objection is by far the most pressing. (shrink)

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

This book offers a ground-up defense of objective morality, drawing inspiration from a wide range of philosophers, including John Locke, Arthur Schopenhauer, Iris Murdoch, Nel Noddings, and David Lewis. The core claim is compassion is our capacity to perceive other creatures' pains, pleasures, and desires. Non-compassionate people are therefore perceptually lacking, regardless of how much factual knowledge they might have. Marshall argues that people who do have this form of compassion thereby fit a familiar paradigm of moral goodness. His (...) argument involves the identification of an epistemic good which Marshall dubs "being in touch". To be in touch with some property of a thing requires experiencing it in a way that reveals that property - that is, experiencing it as it is in itself. Only compassion, Marshall argues, lets us be in touch with others' motivational mental properties. -/- This conclusion about compassion has two important metaethical consequences. First, it generates an answer to the question ";Why be moral?", which has been a central philosophical concern since Plato. Second, it provides the keystone for a novel form of moral realism. This form of moral realism has a distinctive set of virtues: it is anti-relativist, naturalist, and able to identify a necessary connection between moral representation and motivation. The view also implies that there is an epistemic asymmetry between virtuous and vicious agents, according to which only morally good people can fully face reality. (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 (most) (...) 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.

Does theism make a difference to whether there are moral facts? In this paper I suggest that, despite how much uptake this question gets in philosophical literature, it is not well formed. “Theism” leaves too indeterminate what God is like for us to discern what difference God’s existence would make to moral facts. Arguments like the explanans-driven argument for theistic moral realism and the explanationist argument for naturalist moral realism both require extra substantive (...) assumptions about God in order to be valid and compelling. Specifically, the arguments must take a stand on whether God is personal or a-personal, and how this affects God’s relation to the natural world. (shrink)

Many philosophers have suspected that the normative importance of morality depends on moral realism. In this paper, I defend a version of this suspicion: I argue that if teleological forms of moral realism, those that posit an objective purpose to human life, are true, then we gain a distinctive kind of reason to do what is morally required. I argue for this by showing that if these forms of realism are true, then doing what is (...) morally required can provide a life with meaning, which is a widespread human need. I also argue that rival meta-ethical views, like anti-realism or non-naturalist realism, cannot make morality meaning-conferring in this way. (shrink)

In his highly engaging book, Speech and Morality, Terence Cuneo advances a transcendental argument for moral realism from the fact that we speak. After summarizing the major moves in the book, I argue that its master argument is not as friendly to non-naturalist versions of moral realism as Cuneo advertises and relies on a diet of insufficient types of speech acts. I also argue that expressivists have compelling replies to each of Cuneo's objections individually, but (...) taken together, Cuneo's objections provide the resources for issuing a new and interesting challenge to expressivists.

Evolutionary debunking arguments, whether defended by Street (2006), Joyce (2006), or others against moral realism, or by Plantinga (1993, 2011) and others against atheism, seek to determine the implications of the still-dominant worldview of naturalism. Examining them is thus a critical component of any defense of a theistic philosophy of nature. Recently, several authors have explored the connection between evolutionary debunking arguments against moral realism (hence: EDAs) and Plantinga’s evolutionary argument against naturalistic atheism (hence: EAAN). Typically, (...) responses in this vein have been critical of EDAs, arguing that they are in some way self-undermining. Different critics have argued that, in the course of defending the EAAN, the theist loses her best response to the probabilistic argument from evil for atheism. Here, I provide the first systematic comparison of all three arguments—EDAs, the EAAN, and the problem of evil—and suggest that the first charge succeeds while the second fails. (shrink)

An increasing number of moral realists and anti-realists have recently attempted to support their views by appeal to science. Arguments of this kind are typically criticized on the object-level. In addition, however, one occasionally also comes across a more sweeping metatheoretical skepticism. Scientific contributions to the question of the existence of objective moral truths, it is claimed, are impossible in principle; most prominently, because such arguments impermissibly derive normative from descriptive propositions, such arguments beg the question against non- (...) class='Hi'>naturalist moral realism, science cannot inform conceptual accounts of moral judgements, and the conceptual is logically prior to the empirical. My main aim in this paper is to clarify and critically assess these four objections. Moreover, based on this assessment, I will formulate four general requirements that science-based arguments in favor of moral realism and anti-realism should meet. It will turn out that these arguments are limited in several ways, and that some existing arguments have been unsound. Yet it is still possible in principle for the empirical sciences to contribute to the moral realism/anti-realism debate. (shrink)

Can there be an objective morality without God? Derek Parfit argues that it can and offers a theory of morality that is neither theistic nor naturalistic. This book provides a critical assessment of Parfit's metaethical theory. Jakobsen identifies some problems in Parfit’s theory – problems concerning moral normativity, the ontological status of morality, and evolutionary influence on our moral beliefs – and argues that theological resources can help solve them. By showing how Parfit’s theory may be improved by (...) the help of theology, Jakobsen demonstrates the relevance of theology in philosophical and metaethical debates and argues that Christian theism offers a better explanation of morality than what Parfit’s non-naturalism does.

The main aim of this thesis is to defend moral realism. In chapter 1, I argue that moral realism is best understood as the view that moral sentences have truth-value, there are moral properties that make some moral sentences true, and moral properties are not reducible to non- moral properties. Realism is contrasted with non-cognitivism, error-theory and reductionism, which, in brief, deny, and, respectively. In the introductory chapter, it is also (...) argued that there are some prima facie reasons to assume that non-cognitivism and error-theory are erroneous. In chapters 2 and 3, I suggest that the two main forms of reductionism, analytic and synthetic reductionism, are mistaken. In chapter 4, I argue that the considerations in the previous chapters in relation to non-cognitivism, error-theory and reductionism provide support to moral realism. It is also suggested that these considerations make it plausible to hypothesise that moral properties depend on non- moral properties in a way I refer to as ‘the realist formula’. The realist formula confirms moral realism since it implies that moral properties are not reducible to non- moral properties. In chapters 5, 6 and 7, I argue that moral realism, much owing to the realist formula, is able to explain significant meta-ethical issues regarding moral disagreement, moral reason and moral motivation. Among other things, externalism concerning moral motivation is defended. The explanatory value of moral realism in relation to these meta-ethical issues is taken to suggest that this view is preferable to non-cognitivism, error-theory and reductionism. Some of the meta-ethical issues discussed in these chapters, particularly moral disagreement and motivation, have been thought to provide support to non-cognitivism and error-theory. I maintain that since realism, unlike reductionism, is able to counter these arguments, it justifies us in upholding the view that moral sentences have truth-value and the view that there are moral properties. In chapter 8, various objections against realism with regard to the dependence of moral properties on non- moral properties are responded to. In chapter 9, I consider an influential argument to the effect that moral properties are not involved in causal explanations. I maintain that this argument fails and that it therefore is reasonable to assume that moral properties are natural properties. However, the discussions in chapters 8 and 9 also suggest that moral realism might face problems that cannot be thoroughly discussed in this thesis. (shrink)

Yong Huang presents criticisms of Neo-Aristotelian meta-ethical naturalism and argues Zhu Xi’s Neo-Confucian approach is superior in defending moral realism. After presenting Huang’s criticisms of the Aristotelian metaethical naturalist picture, such as that of Rosalind Hursthouse, I argue that Huang’s own views succumb to the same criticisms. His metaethics does not avoid an allegedly problematic ‘gap,’ whether ontological or conceptual, between possessing a human nature and exemplifying moral goodness. This ontological gap exists in virtue of the (...) fact that it is possible for there to be bad people, and the conceptual gap exists in virtue of the fact that people are not ‘good’ (in that sense of being a good agent) merely because they are human. Aristotelians and Confucians both should reject that such gaps are problematic. I conclude by proposing that Huang is better understood as criticizing the Aristotelian move from scientific-empirical facts about human nature to the objective prescriptivity of moral norms. But so too I argue that Confucians should not follow Huang here either. There is good scientific evidence that would be supportive of a Confucian analysis of social virtues and provide one way of responding to those worries about the scientific-empirical accessibility of facts about the good life.

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 (...) class='Hi'>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.

In this module I set out the Moral Non-Naturalism of Pūrva Mīmāṃsā as a version of Deontology that defines duty in terms of its beneficent properties. It elucidates the scheme of right living according to ordinance or command. Whereas natural accounts of moral terms suffer from circularity (by merely re-naming of a natural property with a moral term, which then serves to justify its moral appraisal), proponents of Mīmāṃsā defend their position by offering the Vedas as (...) constituting independent evidence about what yields goodness. In some ways, the argument provided by the defenders of Mīmāṃsā prefigure Moore's complaint of the Naturalistic Fallacy, but the Mīmāṃsā approach doesn't claim that defining natural properties by ethical terms is a fallacy: it is simply circular.

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.

I discuss the second of the three theses advanced by Anscombe in ‘Modern Moral Philosophy’. The focus is the nature of entities to which – if Anscombe’s diagnosis is correct – ought and cognate modals are assumed by modern moral philosophers to refer. I reconstruct the alternative account offered by Anscombe of viable and justified ‘Aristotelian’ modals – as contrasted with mysterious and unjustified ‘Kantian’ modals; I discuss the nature and status of ‘Aristotelian necessity’ to which such legitimate (...) modals refer to. I conclude with the claims that Anscombe’s account of modern moral philosophy is viciously parochial, reducing it to Oxford philosophy from the Thirties and Forties and its immediate antecedents; that her historical reconstruction is vitiated by lack of awareness of the existence of law-views of morality preceding Christian theology, artful anticipation of secularization in order to fit her picture of modern moral philosophy as the ‘day after’ of Christianity; that Aquinas’s and her own view of natural morality as made of rational moral judgments laws is incompatible with both her predilection for ‘divine law’ instead of plain down-to-earth ‘natural law’; that her strained reconstruction of a Christian-Jewish-Stoic view of morality as law promulgated by God has little to share with any reconstruction of the Biblical moral traditions meeting academic standard and in more detail there is no possible translation of Torah as Law; and that her criticism hits just targets from the old little British world she was familiar with, while leaving Kantian ethics unaffected. -/- .

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

Non-naturalist realists are committed to the belief, famously voiced by Parfit, that if there are no non-natural facts then nothing matters. But it is morally objectionable to conditionalise all our moral commitments on the question of whether there are non-natural facts. Non-natural facts are causally inefficacious, and so make no difference to the world of our experience. And to be a realist about such facts is to hold that they are mind-independent. It is compatible with our experiences that (...) there are no non-natural facts, or that they are very different from what we think. As Nagel says, realism makes scepticism intelligible. So the non-naturalist must hold that you might be wrong that your partner matters, even if you are correct about every natural, causal fact about your history and relationship. But to hold that conditional attitude to your partner would be a moral betrayal. So believing non-naturalist realism involves doing something immoral. (shrink)

This paper offers a simple response to the Moral Twin Earth (MTE) objection to Naturalist Moral Realism (NMR). NMR typically relies on an externalist metasemantics such as a causal theory of reference. The MTE objection is that such a theory predicts that terms like ‘good’ and ‘right’ have a different reference in certain twin communities where it’s intuitively clear that the twins are talking about the same thing when using ‘good’. I argue that Boyd’s causal regulation (...) theory, the original target of the MTE objection, was never vulnerable to this objection. The theory contains an epistemic constraint on reference which implies that either the property that causally regulates uses of ‘good’ isn’t different for the twin communities or, in scenarios where the reference is different, the communities diverge in ways where it’s not intuitively clear that ‘good’ has the same reference for them.

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

Do the facts of evolution generate an epistemic challenge to moral realism? Some think so, and many “evolutionary debunking arguments” have been discussed in the recent literature. But they are all murky right where it counts most: exactly which epistemic principle is meant to take us from evolutionary considerations to the skeptical conclusion? Here, I will identify several distinct species of evolutionary debunking argument in the literature, each one of which relies on a distinct epistemic principle. Drawing on (...) recent work in epistemology, I will show that most of these initially plausible principles are false, spoiling the arguments that rely on them. And we will see that each argument threatens only one popular view of moral psychology: a “Representationalist” view on which our moral judgments rely crucially on a mental intermediary—e.g. a sentiment, gut reaction, or affect-laden intuition—delivered by our evolved moral faculty. In the end, only one evolutionary debunking argument remains a menace: an “ Argument from Symmetry ” that I will introduce to the literature. But we will see that it should worry only all naturalists, pressuring them into a trilemma: give up moral realism, accept a rationalism that is incongruous with naturalism, or give up naturalism. Non-naturalists are free and clear. (shrink)

A debate has recently appeared regarding whether non-naturalism is better than other metaethical views at explaining moral progress. I shall take the occasion of this debate to present a novel debunking dilemma for moral non-naturalists, extending Sharon Street's Darwinian one. I will argue that moral progress indicates that our moral attitudes tend to reflect contingent sociocultural and psychological factors. For non-naturalists, there is then either a relation between these factors and the moral facts, non-naturalistically construed, (...) or there is not. If there is no relation, the contingent factors are unlikely to lead to moral knowledge. If there is a relation, they must be likely to lead to non-naturalist-style moral knowledge, but no theoretically virtuous explanation of moral progress is likely to accommodate non-naturalist commitments. It follows that non-naturalist moral realism cannot explain our moral knowledge. I call this a contingentist challenge to non-naturalism. (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)

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

I develop an account of moral perception which is able to deal well with familiar naturalistic non-realist complaints about ontological extravagance and ‘queerness’. I show how this account can also ground a cogent response to familiar objections presented by Simon Blackburn and J.L. Mackie. The familiar realist's problem about relativism, however, remains.

Some moral realists claim that moral facts are a species of natural fact, amenable to scientific investigation. They argue that these moral facts are needed in the best explanations of certain phenomena and that this is evidence that they are real. In this paper I present part of a biological account of the function of morality. The account allows the identification of a plausible natural kind that could play the explanatory role that a moral kind would (...) play in naturalist realist theories. It is therefore a candidate for being the moral kind. I argue, however, that it will underdetermine the morally good, that is, identifying the kind is not sufficient to identify what is good. Hence this is not a natural moral kind. Its explanatory usefulness, however, means that we do not have to postulate any further (moral) facts to provide moral explanations. Hence there is no reason to believe that there are any natural moral kinds. (shrink)

This paper focuses on a recently articulated, emergentist conception of ethical naturalism and its commitment to causal efficacy, or the idea that moral properties have causal powers, along with its supporting commitment to moral causation. After I reconstruct the theory, I explain how it offers some interesting theoretical benefits to moral realists in virtue of its commitment to causal efficacy. Then, after locating some examples of moral causation in support of this commitment, I present and respond (...) to five objections to such causation, which all threaten to undermine this support. Lastly, I consider a very serious problem that the theory faces in virtue of positing emergent moral properties as responsible for moral causation – namely, the problem of downward moral causation. I describe this problem in detail and argue that, as it stands, it does not spell doom for the theory. (shrink)

Survey article on Naturalism dealing with Hume's NOFI (including Prior's objections), Moore's Naturalistic Fallacy and the Barren Tautology Argument. Naturalism, as I understand it, is a form of moral realism which rejects fundamental moral facts or properties. Thus it is opposed to both non-cognitivism, and and the error theory but also to non-naturalism. General conclusion: as of 1991: naturalism as a program has not been refuted though none of the extant versions look particularly promising.

A basic challenge to naturalistic moral realism is that, even if moral properties existed, there would be no way to naturalistically represent or track them. Here, the basic structure for a tracking account of moral epistemology is given in empirically respectable terms, based on a eudaimonist conception of morality. The goal is to show how this form of moral realism can be seen as consistent with the details of evolutionary biology as well as being (...) amenable to the most current understanding of representationalist or correspondence theories of truth.

The purpose of this paper is to examine the relationship between naturalism and morality and to assess their compatibility. Naturalism is defined as respect for science, for its methods and results. From this respect for science, one can infer two distinct philosophical naturalisms: the methodological and the metaphysical. The relationship between these forms of naturalism and morality depends on the correct conception of morality. This paper differentiates between objectively realistic conception and all other conceptions and argues that while other conceptions (...) can easily fit morality into a naturalistic worldview, objectively realistic conception faces theoretical challenges, including the challenge of explaining how moral facts and concepts play an explanatory role and the challenge of bridging the is/ought gap. The paper focuses on Railton's ethical naturalism as a prominent naturalistic theory of morality and evaluates its ability to overcome these challenges. The conclusion is that, so long as we consider a theory like Railton's, naturalism and realistically conceived morality are incompatible. (shrink)

In this paper, I motivate skepticism about the causal efficacy of moral properties in two ways. First, I highlight a tension that arises between two claims that moral realists may want to accept. The first claim is that physically indistinguishable things do not differ in any causally efficacious respect. The second claim is that physically indistinguishable things that differ in certain historical respects have different moral properties. The tension arises to the extent to which these different (...) class='Hi'>moral properties are supposed to have different effects on people. I will introduce a class of cases in which this tension arises and suggest that the moral properties in these cases have no causal power. I will also question whether there are differences between the moral properties in these cases and moral properties in other cases that do not involve physically indistinguishable things that could make the latter moral properties causally efficacious. The second way that I motivate skepticism consists in pointing out a unique feature of cases in which moral properties are supposed both to supervene on historical properties and to be causally efficacious. These cases allow us to change moral properties with alleged effects while we hold constant the nonmoral candidates for causal contribution to those effects. This feature of these cases is unique because in most other cases the moral properties supervene on the physical properties in the nonmoral candidates, such that we cannot change the former while holding constant the latter. This way of changing moral properties provides empirical grounds for testing their causal efficacy. (shrink)

This paper is about how moral disagreement matters for metaethics. It has four parts. In the first part I argue that moral facts are subject to a certain epistemic accessibility requirement. Namely, moral facts must be accessible to some possible agent. In the second part I show that because this accessibility requirement on moral facts holds, there is a route from facts about the moral disagreements of agents in idealized conditions to conclusions about what (...) class='Hi'>moral facts there are. In the third part I build on this route to show that (*) if there is significant moral disagreement in idealized conditions, then our understanding of morality is fatally flawed and we should accept relativism over non-naturalism and quasi-realism. So, if, like many, you think that there would be significant moral disagreement in idealized conditions, you should hold that our understanding of morality is fatally flawed and reject non-naturalism and quasi-realism. In the fourth part of this paper I show that (*) undermines the plausibility of non-naturalism, quasi-realism, and the view that our understanding of morality is not fatally flawed even if we do not have sufficient reason to believe that there would be significant moral disagreement in idealized conditions.

The dominant theory of the evolution of moral cognition across a variety of fields is that moral cognition is a biological adaptation to foster social cooperation. This chapter argues, to the contrary, that moral cognition is likely an evolutionary exaptation: a form of cognition where neurobiological capacities selected for in our evolutionary history for a variety of different reasons—many unrelated to social cooperation—were put to a new, prosocial use after the fact through individual rationality, learning, and the (...) development and transmission of social norms. This chapter begins with a brief overview of the emerging behavioral neuroscience of moral cognition. It then outlines a novel theory of moral cognition that I have previously argued explains these findings better than alternatives. Finally, it shows how the evidence for this theory of moral cognition and human evolutionary history together suggest that moral cognition is likely not a biological adaptation. Instead, like reading sheet music or riding a bicycle, moral cognition is something that individuals learn to do—in this case, in response to sociocultural norms created in our ancestral history and passed down through the ages to enable cooperative living.

As the intuitions about moral phenomenology shows the metaphysical distinction between mind-dependent and mind-independent properties has set the metaethical distinction between normativity and objectivity in ethics. Traditionally, many arguments were built in order to show that moral realists cannot account, in naturalist vocabulary, for the process of determining moral reference due to the desiderative disposition taken to be necessarily part of the meaning of moral terms. This dissertation assess some anti-realists arguments like is-ought thesis, the (...) argument from queerness, the argument from relativity and the open question argument. In what follows I propose the semantics elaborated by Cornell realism in order to address these arguments, especially the open question argument. However, as Moral Twin Earth test shows us the semantic proposed by Boyd is incomplete. Therefore I also evaluate a second attempt taken by Cornell realists such as Brink and Copp, based on Putnan's notion of referential intentions. (shrink)

First, I discuss naturalism's meaning in philosophy and then the sense in which it has been introduced in ethics: that of American Naturalism, that of Dewey’s pragmatism, the sense of a negation of Moore’s negation of naturalism, the neo-Aristotelian, and the external realist. I will argue a fundamental heterogeneity of these meanings. I will add that the reasons for the apparent unity of a naturalist front in recent philosophical debates lie more in the sociology of knowledge. I will suggest (...) that there is one sense in which a naturalism claim may be defended, the sense of Aristotle and Dewey, according to which moral good is not specifically moral. I will add that programs of scientific exploration into biological bases of behaviour and coordination of behaviour within groups are highly promising but are in no sense ‘naturalistic’ and are indeed compatible with ethical intuitionism or Kantian ethics.

Nietzsche’s late writings present a value opposition of health and decadence based in his conception of organic life. While this appears to be a moral ideal that risks the naturalistic fallacy of directly deriving norms from facts, it instead describes a meta-ethical ideal: the necessary conditions for any kind of moral agency. Nietzsche’s ideal of health not only evades but also dissolves the naturalistic fallacy by suggesting that the specific content of morality is irrelevant. If health is measured (...) by power over one’s drives rather than the environment, then the source of moral conflict—organic life’s essential tendency toward domination—is surmounted by successful integration of any moral norms, regardless of content. Nietzsche’s concept of health draws on his characterization of organic life as essentially ‘exploitation’: growth through domination of the environment (BGE 259, GM II: 12). In animals, power coincides with happiness, while health and decadence track the correspondence between instinct and happiness (TI II: 11). This simple picture is complicated by the Genealogy, where Nietzsche depicts human nature as an animal illness caused by civilization’s disruption of the natural correspondence of instinct and happiness. Civilization shapes this ‘sick animal’ into the distinctly human ‘sovereign individual’ (GM III: 13, II: 2), restoring the harmony of instinct and happiness in an internal hierarchy of drives. So, sovereign individuality is a distinctly human model of health. Although life is exploitation, human health does not coincide with greater environmental power, but rather an internal qualitative expansion of power: greater variety and tension among drives, greater ‘wholeness in diversity’ in the ‘social structure’ of the self (BGE 212, 12). Nonetheless, health is not a moral criterion, but instead the precondition of moral agency. The subordination of drives to a commanding hierarchy grounds the ability to uphold any moral principles at all, to make and keep promises to oneself and others. Moral agency coincides, in turn, with overcoming the source of moral conflict in organic life’s drive for growth. The unification of opposing drives provides pleasure in power over oneself rather than one’s environment, the ‘happiness of high tension’ among drives (BGE 260), and in environmental resistance, a need for ‘equal opponents’ (TI IX: 38, EH 1: 7). Consequently, Nietzsche’s meta-ethical ideal supports a moral pluralism that supports any moral content. Moral conflicts arise precisely to the degree individuals are incapable of achieving moral agency, but they dissolve as moral agency of any kind is more widely achieved. (shrink)

The dominant theory of the evolution of moral cognition across a variety of fields is that moral cognition is a biological adaptation to foster social cooperation. This chapter argues, to the contrary, that moral cognition is likely an evolutionary exaptation: a form of cognition where neurobiological capacities selected for in our evolutionary history for a variety of different reasons—many unrelated to social cooperation—were put to a new, prosocial use after the fact through individual rationality, learning, and the (...) development and transmission of social norms. This chapter begins with a brief overview of the emerging behavioral neuroscience of moral cognition. It then outlines a novel theory of moral cognition that I have previously argued explains these findings better than alternatives. Finally, it shows how the evidence for this theory of moral cognition and human evolutionary history together suggest that moral cognition is likely not a biological adaptation. Instead, like reading sheet music or riding a bicycle, moral cognition is something that individuals learn to do—in this case, in response to sociocultural norms created in our ancestral history and passed down through the ages to enable cooperative living.

The following scenario seems possible: a community uses concepts that play the same role in guiding actions and shaping social life as our normative concepts, and yet refer to something else. As Eklund argues, this apparent possibility poses a problem for any normative realist who aspires to vindicate the thought that reality itself favors our ways of valuing and acting. How can realists make good on this idea, given that anything they might say in support of the privileged status of (...) our normative concepts can be mirrored by the imagined community? E.g., the realist might claim that using our concepts is what we ought to do if we are to describe normative facts correctly, but members of the other community can claim the same about their concepts, using their own concept of ought. A promising approach to this challenge is to try to rule out the possibility of alternative normative concepts, by arguing that any concepts that have the same normative role must share a reference as well. In this paper I argue that normative quasi-naturalism, a view that combines expressivism about normative discourse with a naturalist metaphysics of normativity, supports referential normativity and solves the problem of alternative normative concepts.

Non-naturalism – roughly the view that normative properties and facts are sui generis and incompatible with a purely scientific worldview – faces a difficult challenge with regard to explaining why it is that the normative features of things supervene on their natural features. More specifically: non-naturalists have trouble explaining the necessitation relations, whatever they are, that hold between the natural and the normative. My focus is on Stephanie Leary's recent response to the challenge, which offers an attempted non-naturalism-friendly explanation for (...) the supervenience of the normative on the natural by appealing to hybrid properties, the essences of which link them to both natural and sui generis normative properties in suitable ways. I argue that despite its ingenuity, Leary's solution fails. This is so, I claim, because there are no hybrid properties of the sort that her suggestion appeals to. If non-naturalists are to deal with the supervenience challenge, they will have to find another way of doing so. (shrink)

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)

I evaluate the metaphysical plausibility of the non-naturalist view of moral properties. I will mainly concentrate my evaluation on the views of Shafer-Landau (henceforth just S-L) whose defence of moral non-naturalism is the most lucid and vigorous so far. I shall try to show its metaphysical problems and defend Jackson’s Occamist naturalism about moral properties which I consider to be more consistent with the supervenience platitude.

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.

Cornell realists maintain that irreducible moral properties have earned a place in our ontology in virtue of the indispensable role they play in a variety of explanations. These explanations can be divided into two groups: those that employ thin ethical concepts and those that employ thick ethical concepts. Recent work on thick concepts suggests that they are not inherently evaluative in their meaning. If correct, this creates problems for the moral explanations of Cornell realists, since the most persuasive (...) moral explanations are those that employ thick concepts. If thick concepts are not inherently evaluative, then the most plausible explanations on offer cannot support Cornell realism. Moral explanations employing thin concepts, however, are too flimsy to support the view. Unless proponents can develop a compelling story about thick concepts or thin explanations, Cornell realism is in trouble. (shrink)
