This paper defends moral realism against Sharon Street’s “Darwinian Dilemma for Realist Theories of Value” (this journal, 2006). I argue by separation of cases: From the assumption that a certain normative claim is true, I argue that the first horn of the dilemma is tenable for realists. Then, from the assumption that the same normative claim is false, I argue that the second horn is tenable. Either way, then, the Darwinian dilemma does not add anything to realists’ epistemic (...) worries. (shrink)

The essay argues that while there is no general agreement on whether moral realism is true, there is general agreement on at least some of the moral obligations that we have if moral realism is true. Given that moral realism might be true, and given that we know some of the things we ought to do if it is true, we have a reason to do those things. Furthermore, this reason is itself an (...) objective moral reason. Thus, if moral realism might be true, then it is true. (shrink)

Epistemological objections to moral realism allege that realism entails moral skepticism. Many philosophers have assumed that theistic moral realists can easily avoid such objections. In this article, I argue that things are not so easy: theists run the risk of violating an important constraint on replies to epistemological objections, according to which replies to such objections may not rely on substantive moral claims of a certain kind. Yet after presenting this challenge, I then argue (...) that theists can meet it, successfully replying to the objections without relying on the problematic kinds of substantive moral claims. Theists have a distinctive and plausible reply to epistemological objections to moral realism. (shrink)

Moral realists believe that there are objective moral truths. According to one of the most prominent arguments in favour of this view, ordinary people experience morality as realist-seeming, and we have therefore prima facie reason to believe that realism is true. Some proponents of this argument have claimed that the hypothesis that ordinary people experience morality as realist-seeming is supported by psychological research on folk metaethics. While most recent research has been thought to contradict this claim, four (...) prominent earlier studies indeed seem to suggest a tendency towards realism. My aim in this paper is to provide a detailed internal critique of these four studies. I argue that, once interpreted properly, all of them turn out in line with recent research. They suggest that most ordinary people experience morality as “pluralist-” rather than realist-seeming, i.e., that ordinary people have the intuition that realism is true with regard to some moral issues, but variants of anti-realism are true with regard to others. This result means that moral realism may be less well justified than commonly assumed. (shrink)

Evolutionary debunking arguments claim that evolution has influenced our moral faculties in such a way that, if moral realism is true, then we have no positive moral knowledge. I present several popular objections to the standard version of this argument, then give a new EDA that has clear advantages in responding to these objections. Whereas the Standard EDA argues that evolution has selected for many moral beliefs with certain contents, this New EDA claims that evolution (...) has selected for one belief: belief in the claim that categorical reasons exist. If moral realism is true, then this claim is entailed by all positive moral claims, and belief in it is defeated due to evolutionary influence. This entails that if realism is true, then we have no positive moral knowledge. While there may be objections against this New EDA, it is much stronger than the Standard EDA, and one realists ought to worry about. (shrink)

Evolutionary debunking arguments move from a premise about the influence of evolutionary forces on our moral beliefs to a skeptical conclusion about those beliefs. My primary aim is to clarify this empirically grounded epistemological challenge. I begin by distinguishing among importantly different sorts of epistemological attacks. I then demonstrate that instances of each appear in the literature under the ‘evolutionary debunking’ title. Distinguishing them clears up some confusions and helps us better understand the structure and potential of evolutionary debunking (...) arguments. (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. (shrink)

This paper considers John Doris, Stephen Stich, Alexandra Plakias, and colleagues’ recent attempts to utilize empirical studies of cross-cultural variation in moral judgment to support a version of the argument from disagreement against moral realism. Crucially, Doris et al. claim that the moral disagreements highlighted by these studies are not susceptible to the standard ‘diffusing’ explanations realists have developed in response to earlier versions of the argument. I argue that plausible hypotheses about the cognitive processes underlying (...) ordinary moral judgment and the acquisition of moral norms, when combined with a popular philosophical account of moral inquiry—the method of reflective equilibrium—undercut the anti-realist force of the moral disagreements that Doris et al. describe. I also show that Stich's recent attempt to provide further theoretical support for Doris et al.'s case is unsuccessful. (shrink)

The dominant interpretation of Kant as a moral constructivist has recently come under sustained philosophical attack by those defending a moral realist reading of Kant. In light of this, should we read Kant as endorsing moral constructivism or moral realism? In answering this question we encounter disagreement in regard to two key independence claims. First, the independence of the value of persons from the moral law (an independence that is rejected) and second, the independence (...) of the content and authority of the moral law from actual acts of willing on behalf of those bound by that law (an independence that is upheld). The resulting position, which is called not ‘all the way down’ constructivism, is attributed to Kant. (shrink)

Many philosophers argue that the face-value of moral practice provides presumptive support to moral realism. This paper analyses such arguments into three steps. (1) Moral practice has a certain face-value, (2) only realism can vindicate this face value, and (3) the face-value needs vindicating. Two potential problems with such arguments are discussed. The first is taking the relevant face-value to involve explicitly realist commitments; the second is underestimating the power of non-realist strategies to vindicate that (...) face-value. Case studies of each of these errors are presented, drawn from the writings of Shafer-Landau, Brink and McNaughton, and from recent work in experimental metaethics. The paper then considers weak presumptive arguments, according to which both realist and non-realist vindications of moral practice are possible, but the realist vindications are more natural. It is argued that there is no sense of ‘natural’ available that can make these arguments work. The conclusion is that all extant presumptive arguments for moral realism fail. (shrink)

This paper seeks to clarify and defend the proposition that moral realism is best elaborated as a moral doctrine. I begin by upholding Ronald Dworkin’s anti-Archimedean critique of the error theory against some strictures by Michael Smith, and I then briefly suggest how a proponent of moral realism as a moral doctrine would respond to Smith’s defense of the Archimedeanism of expressivism. Thereafter, this paper moves to its chief endeavor. By differentiating clearly between expressivism (...) and quasi-realism, the paper highlights both their distinctness and their compatibility. In so doing, it underscores the affinities between Blackburnian quasi-realism and moral realism as a moral doctrine. Finally, this paper contends—in line with my earlier work on these matters—that moral realism as a moral doctrine points to the need for some reorienting of meta-ethical enquiries rather than for the abandoning of them.

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-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)

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)

schopenhauer has been ignored in contemporary metaethics, and his commentators rarely attempt to analyze his metaethical views in contemporary terms. This is unfortunate. Schopenhauer has something important to teach us about moral realism.1I have both philosophical and interpretive aims in this paper. My philosophical aim is to show how Schopenhauer's views challenge the contemporary understanding of moral realism. The challenge arises from the fact that, while Schopenhauer's view implies that morality is "real" in a metaphysically- and (...) epistemologically-robust sense, that view denies a central piece of the contemporary definition of moral realism: the cognitive (i.e....

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)

If what we want from moral inquiry were the obtainment of objective moral truths, as moral realism claims it is, then there would be nothing morally unsatisfactory or lacking in a situation, in which we somehow had access to all moral truths, and were fundamentally finished with morality. In fact, that seems to be the realists’ conception of moral heaven. In this essay, however, I argue that some sort of moral wakefulness – that (...) is, always paying attention to the subtleties of life and people, and never taking for granted what their moral significance can possibly be – is an essential moral value, and, therefore, moral realism, which promotes a moral ideal that allows such moral lethargy and inattentiveness is morally objectionable. (shrink)

Here I develop a realist account of normative reasons for action. On the view defended here, there can be correct moral judgments that capture the reasons there are for acting in certain ways; and the reasons themselves are just some of the morally relevant facts of the situation about which the judgment is made. Establishing this account relies crucially, I argue, on an appeal to substantive ethical theory, to a theory that allows for the attribution of truth to the (...) judgments in question. The account defended here can in fact be equally well supported by ethical theories as otherwise diverse as those of Aristotle and Kant. The resulting account is a version of moral realism, but one that is not committed to defending a realist account of the nature of moral value. (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)

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)

In this paper I argue (i) that choosing to abide by realist moral norms would be as arbitrary as choosing to abide by the mere preferences of a God (a difficulty akin to the Euthyphro dilemma raised for divine command theorists); in both cases we would lack reason to prefer these standards to alternative codes of conduct. I further develop this general line of thought by arguing in particular (ii) that we would lack any noncircular justification to concern ourselves (...) with any such realist normative standards. (shrink)

The realist belief in robustly attitude-independent evaluative truths – more specifically, moral truths – is challenged by Sharon Street’s essay “A Darwinian Dilemma for Realist Theories of Value”. We know the content of human normative beliefs and attitudes has been profoundly influenced by a Darwinian natural selection process that favors adaptivity. But if simple adaptivity can explain the content of our evaluative beliefs, any connection they might have with abstract moral truth would seem to be purely coincidental. She (...) continues the skeptical attack in “Objectivity and Truth: You’d Better Rethink It”, concentrating on the intuitionist realism of Ronald Dworkin. The latter sees the issue fundamentally as a holistic choice between moral objectivity and the genocide-countenancing consequences of abandoning objective standards. Street counters that, because of realism’s skeptical difficulties, Dworkin’s Choice (as I call it) actually works in favor of her Euthyphronic antirealism. I will argue that she misrepresents the realist’s skeptical challenge, and that clarifying the character of that challenge renders the case for normative realism much more appealing. Indeed, I claim that Street fails to exclude the genuine possibility of a rational basis for moral truth. (shrink)

Many believe that objective morality requires a theistic foundation. I maintain that there are sui generis objective ethical facts that do not reduce to natural or supernatural facts. On my view, objective morality does not require an external foundation of any kind. After explaining my view, I defend it against a variety of objections posed by William Wainwright, William Lane Craig, and J. P. Moreland.

On an optimistic version of realist moral epistemology, a significant range of ordinary moral beliefs, construed in realist terms, constitute knowledge—or at least some weaker positive epistemic status, such as epistemic justification. The “debunking challenge” to this view grants prima facie justification but claims that it is “debunked” (i.e., defeated), yielding the final verdict that moral beliefs are ultima facie unjustified. Notable candidate “debunkers” (i.e., defeaters) include the so-called “evolutionary debunking arguments,” the “Benacerraf-Field Challenge,” and persistent (...) class='Hi'>moral disagreement among epistemic peers. Such defeaters are best treated as higher-order evidence—viz., evidence contesting the merits of the first-order evidence on which moral beliefs are based. This chapter first develops a theory of higher-order defeat in general, which it then applies to debunking in particular. The result: the challenge fails entirely on epistemic grounds—regardless of whether or not its empirical and metaphysical presuppositions are correct. An advantage of this purely epistemic defense over alternative strategies is that the former extends even to laypersons who themselves lack the expertise necessary to formulate an adequate response. However, this leaves open the prospects for non-epistemological interpretations of debunking (e.g., moral or ontological). The chapter therefore concludes with brief suggestions in that direction.

My aim in this paper is to consider a series of arguments against Dispositional Moral Realism, and argue that these objections are unsuccessful. I will consider arguments that try to either establish a dis-analogy between moral properties and secondary qualities, or try to show that a dispositional account of moral properties fails to account for what a defensible species of moral realism must account for. I also consider criticisms from Simon Blackburn (1993), who argues (...) that there could not be a corresponding perceptual faculty for moral properties, and David Enoch (2011), who argues that Dispositional Moral Realism does not most plausibly explain the difference between moral disagreements and disagreements of mere preference. Finally, I examine a novel criticism concerning the relationship between the diverse variety of moral properties and the range of our normative affective attitudes, arguing that the view has no problem accounting for this diversity.

Environmental ethicists have been arguing for decades that swift action to protect our natural environment is morally paramount, and that our concern for the environment should go beyond its importance for human welfare. It might be thought that the widespread acceptance of moral anti-realism would undermine the aims of environmental ethicists. One reason is that recent empirical studies purport to show that moral realists are more likely to act on the basis of their ethical convictions than anti-realists. (...) In addition, it is sometimes argued that only moral realists can countenance the claim that nature is intrinsically valuable. Against this, we argue that the acceptance of moral anti-realism is no threat to the environmentalist cause. We argue, further, that the acceptance of moral realism is potentially an obstacle to delivering on a third core environmental ethicist demand: namely, that successful action on climate change and environmental destruction requires us to change some of our commonly-held ethical views and to achieve a workable consensus.

Several leading moral philosophers have recently proposed a soft version of moral realism, according to which moral facts—though it is reasonable to postulate them—cannot metaphysically explain other facts (Dworkin 2011; Parfit 2011; Scanlon 2014). However, soft moral realism is faced with what I call the “Hard Problem”, namely, the problem of how this soft version of moral metaphysics could accommodate moral knowledge. This paper reconstructs three approaches to solving the Hard Problem on (...) behalf of the soft realist: the autonomy approach, the intuitionist approach, and the third-factor approach. I then argue that none of them is successful. (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)

Mark Timmons and Terry Horgan have argued that the new moral realism, which rests on the causal theory of reference, is untenable. While I do agree that the new moral realism is untenable, I do not think that Timmons and Horgan have succeeded in showing that it is. I will lay out the case for new moral realism and Horgan and Timmons’ argument against it, and then argue that their argument fails. Further, I will (...) discuss Boyd’s semantic theory as well as attempts to improve upon it, raise serious problems for these semantic accounts, and suggest an alternative view that accounts for our use of moral terms.

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)

The aim of this article is to identify the strongest evolutionary debunking argument against moral realism and to assess on which empirical assumptions it relies. In the recent metaethical literature, several authors have de-emphasized the evolutionary component of EDAs against moral realism: presumably, the success or failure of these arguments is largely orthogonal to empirical issues. I argue that this claim is mistaken. First, I point out that Sharon Street’s and Michael Ruse’s EDAs both involve substantive (...) claims about the evolution of our moral judgments. Next, I argue that combining their respective evolutionary claims can help debunkers to make the best empirical case against moral realism. Some realists have argued that the very attempt to explain the contents of our endorsed moral judgments in evolutionary terms is misguided, and have sought to escape EDAs by denying their evolutionary premise. But realists who pursue this reply can still be challenged on empirical grounds: debunkers may argue that the best, scientifically informed historical explanations of our moral endorsements do not involve an appeal to mind-independent truths. I conclude, therefore, that the empirical considerations relevant for the strongest empirically driven argument against moral realism go beyond the strictly evolutionary realm; debunkers are best advised to draw upon other sources of genealogical knowledge as well. (shrink)

Some moral realists have defended moral realism on the basis of the purported fact that moral facts figure as components in some good explanations of non-moral phenomena. In this paper I explore the relationship between theism and this sort of explanationist defense of moral realism. Theistic explanations often make reference to moral facts, and do so in a manner which is ineliminable in an important respect – remove the moral facts from (...) those explanations, and they suffer as a result. In this respect theistic moral explanations seem to differ from the sorts of moral explanations typically offered by moral explanationists. (shrink)

In recent years an increasing number of psychologists have begun to explore the prevalence, causes and effects of ordinary people’s intuitions about moral realism. Many of these studies have lacked in construct validity, i.e., they have failed to measure moral realism. My aim in this paper accordingly is to motivate and guide methodological improvements. In analysis of prominent existing measures, I develop general recommendations for overcoming ten prima facie serious worries about research on folk moral (...) realism. G1 and G2 require studies’ answer choices to be as metaethically comprehensive as methodologically feasible. G3 and G4 prevent fallacious inferences from intuitions about related debates. G5 and G6 limit first-order moral and epistemic influences. G7 address studies’ instructions. And G8 and G9 suggest tests of important psychological presuppositions. (shrink)

In this paper I argue that the explanationist argument in favour of moral realism fails. According to this argument, the ability of putative moral properties to feature in good explanations provides strong evidence for, or entails, the metaphysical claims of moral realism. Some have rejected this argument by denying that moral explanations are ever good explanations. My criticism is different. I argue that even if we accept that moral explanations are (sometimes) good explanations (...) the metaphysical claims of realism do not follow. (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.

Does evolutionary theory have the potential to undermine morality? In his book The Evolution of Morality, Richard Joyce (2006) argues for a positive answer. He contends that an evolutionary account of morality would undermine moral judgements and lend support to moral scepticism. I offer a critique of Joyce’s argument. As it turns out, his case can be read in two different ways. It could be construed as an argument to establish a general scepticism about the justification of (...) class='Hi'>moral judgements. Or it could be read as an argument that targets only a particular meta-ethical position, namely moral realism. My claim is that it fails on both interpretations. There is no reason to believe that evolutionary considerations undermine morality. (shrink)

A short review of Russ Shafer-Landau's Moral Realism: A Defence.

If what is morally right or wrong were ultimately a function of our opinions, then even such reprehensible actions as genocide and slavery would be morally right, had we approved of them. Many moral philosophers find this conclusion objectionably permissive, and to avoid it they posit a moral reality that exists independently of what anyone thinks. The notion of an independent moral reality has been subjected to meticulous metaphysical, epistemological and semantic criticism, but it is hardly ever (...) examined from a moral point of view. In this essay I offer such a critique. I argue that the appeal to an independent moral reality as a ground for moral obligations constitutes a substantive moral mistake. However, I do not conclude from this that we must therefore embrace the opposite view that moral truths are ultimately dependent on our attitudes. Rather, I suggest that we reject both of these views and answer the classic meta-ethical question “Is what we morally ought to do ultimately a function of our actual attitudes, or determined independently of them?” with Neither.

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.

There has been much recent debate on the question of whether Kant is to be best understood as a moral realist or a moral constructivist. In an attempt to resolve this debate I examine whether moral constructivism is a form of moral idealism, briefly contrast realism and idealism, and draw on work in social ontology to look at the different accounts of moral ontology implicit in realist and constructivist accounts. As a result of this (...) investigation I conclude that Kant is a moral constructivist. (shrink)

This paper concerns a prima facie tension between the claims that (a) agents have normative reasons obtaining in virtue of the nature of the options that confront them, and (b) there is a non-trivial connection between the grounds of normative reasons and the upshots of sound practical reasoning. Joint commitment to these claims is shown to give rise to a dilemma. I argue that the dilemma is avoidable on a response dependent account of normative reasons accommodating both (a) and (b) (...) by yielding (a) as a substantial constraint on sound practical reasoning. This fact is shown to have significance for the contemporary dialectic between moral realists and their opponents. (shrink)

Peter Railton argues for a form of moral realism which holds that moral judgments can bear truth values in a fundamental non-epistemic sense of truth; that moral properties are objective, though relational; that moral properties supervene upon natural properties, and may be reducible to them; that moral inquiry is of a piece with empirical inquiry. He also thinks that it cannot be known a priori whether bivalence holds for moral judgments, and that a (...) rational agent may fail to have a reason for obeying moral imperatives, although they may be applicable to him. In this paper, Railton's moral theories are carefully examined and compared with noncognitivistic ones. (shrink)

Debunking skeptics claim that our moral beliefs are formed by processes unsuited to identifying objective facts, such as emotions inculcated by our genes and culture; therefore, they say, even if there are objective moral facts, we probably don’t know them. I argue that the debunking skeptics cannot explain the pervasive trend toward liberalization of values over human history, and that the best explanation is the realist’s: humanity is becoming increasingly liberal because liberalism is the objectively correct moral (...) stance.

The existence of fundamental moral disagreements is a central problem for moral realism and has often been contrasted with an alleged absence of disagreement in mathematics. However, mathematicians do in fact disagree on fundamental questions, for example on which set-theoretic axioms are true, and some philosophers have argued that this increases the plausibility of moral vis-à-vis mathematical realism. I argue that the analogy between mathemat- ical and moral disagreement is not as straightforward as those (...) arguments present it. In particular, I argue that pluralist accounts of mathematics render fundamental mathematical disagreements compatible with mathematical realism in a way in which moral disagreements and moral realism are not.

How should we understand the notion of moral objectivity? Metaethical positions that vindicate morality’s objective appearance are often associated with moral realism. On a realist construal, moral objectivity is understood in terms of mind-, stance-, or attitude-independence. But realism is not the only game in town for moral objectivists. On an antirealist construal, morality’s objective features are understood in virtue of our attitudes. In this paper I aim to develop this antirealist construal of (...) class='Hi'>moral objectivity in further detail, and to make its metaphysical commitments explicit. I do so by building on Sharon Street’s version of “Humean Constructivism”. Instead of the realist notion of attitude-independence, the antirealist account of moral objectivity that I articulate centres on the notion of standpoint-invariance. While constructivists have been criticized for compromising on the issue of moral objectivity, I make a preliminary case for the thesis that, armed with the notion of standpoint-invariance, constructivists have resources to vindicate an account of objectivity with just the right strength, given the commitments of ordinary moral thought and practice. In support of this thesis I highlight recent experimental findings about folk moral objectivism. Empirical observations about the nature of moral discourse have traditionally been taken to give prima facie support to moral realism. I argue, by contrast, that from what we can tell from our current experimental understanding, antirealists can capture the commitments of ordinary discourse at least as well as realists can.

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.

We argue that contrary to received wisdom, non-naturalist moral realism has an advantage over its naturalist rivals with respect to at least one thorny problem in moral epistemology. We call this problem 'the projectability challenge'. It is the challenge of explaining how it is possible for individuals to apply their moral knowledge to a variety of kinds of new (to them) cases and also how it is possible for individuals to learn from moral experience. By (...) developing an account of and carefully examining what we take to be the underlying metaphysics and psychology behind traditional moral non-naturalism, we show that the non-naturalist is able to meet the projectability challenge. While we do not claim to show that the naturalist cannot meet the projectability challenge, we argue that it will be difficult for them to do so. (shrink)

Are there objective moral truths, i.e. things that are morally right, wrong, good, or bad independently of what anybody thinks about them? To answer this question more and more scholars have recently turned to evidence from psychology, neuroscience, cultural anthropology, and evolutionary biology. This book investigates this novel scientific approach in a comprehensive, empirically-focused, and partly meta-theoretical way. It suggests that while it is possible for the empirical sciences to contribute to the moral realism/anti-realism debate, most (...) arguments that have so far been proposed fail (because they misrepresent, cherry-pick, or overlook the invalidity of (parts of) the available scientific evidence). The book’s main chapters address five prominent science-based arguments for or against the existence of objective moral truths: the argument from moral disagreement, the evolutionary debunking argument, the sentimentalist argument, the presumptive argument, and the projectivist argument. Thomas Pölzler investigates in which sense the underlying empirical hypotheses would have to be true in order for these arguments to work, and then shows how the available scientific evidence fails to support them. Finally, he makes suggestions as to how to test these hypotheses in a more valid way. Moral Reality and the Empirical Sciences is an important contribution to the moral realism/anti-realism debate that will appeal to philosophers and scientists interested in moral psychology and metaethics.
