Commentators regularly attribute to Frege realist, idealist, and quietist responses to metaphysical questions concerning the abstract objects he calls ‘thoughts’. But despite decades of effort, the evidence offered on behalf of these attributions remains unconvincing. I argue that Frege deliberately avoids commitment to any of these positions, as part of a metaphysical separatist policy motivated by the fact that logic is epistemologically autonomous from metaphysics. Frege’s views and arguments prove relevant to current attempts to argue for epistemological autonomy, particularly that (...) of ethics. (shrink)

I argue that, given evidence of the factors that tend to distort our intuitions, ethical intuitionists should disown a wide range of common moral intuitions, and that they should typically give preference to abstract, formal intuitions over more substantive ethical intuitions. In place of the common sense morality with which intuitionism has traditionally allied, the suggested approach may lead to a highly revisionary normative ethics.

In earlier work, I argued that observed changes in moral values over human history are best explained as cognitive progress: societies tend over the long term to move closer to the objective moral truth. It is also true that, in recent decades, liberal democracies have moved strongly in the direction of greater government regulation and wealth redistribution. Does this mean that extensive regulation and redistribution are objectively good? I argue that the answer is no; these recent trends are importantly different (...) from earlier examples of moral progress in ways that enable them to be satisfyingly explained without adverting to objective moral correctness. (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.

We aim to develop a form of debunking argument according to which an agent’s belief is undermined if the reasons she gives in support of her belief are best explained as rationalizations. This approach is a more sophisticated form of what Shaun Nichols has called best-explanation debunking, which he contrasts with process debunking, i.e., debunking by means of showing that a belief has been generated by an epistemically defective process. In order to develop our approach, we identify an example of (...) such a best-explanation debunking argument in Joshua Greene’s attack on deontology. After showing that this argument is not an instance of process debunking, we offer our best-explanation approach as a generalization of Greene’s argument. Finally, we defend our approach by showing that it is not susceptible to some criticisms that Nichols has leveled against a less sophisticated form of best-explanation debunking. (shrink)

This paper is a critical discussion of Ernest Sosa’s recent analysis of reflective knowledge.

What is the significance of empirical moral psychology for metaethics? In this article we take up Michael Ruse’s evolutionary debunking argument against moral realism and reassess it in the context of the empirical state of the art. Ruse’s argument depends on the phenomenological presumption that people generally experience morality as objective. We demonstrate how recent experimental findings challenge this widely-shared armchair presumption and conclude that Ruse’s argument fails. We situate this finding in the recent debate about Carnapian explication and argue (...) that it illustrates the necessary role that empirical moral psychology plays in explication preparation. Moral psychology sets boundaries for reasonable desiderata in metaethics and, therefore, it is necessary for metaethics. (shrink)

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 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.

Many metaethicists assume that our normative judgments are both by and large true, and the product of causal forces. In other words, many metaethicists assume that the set of normative judgments that causal forces have led us to make largely coincides with the set of true normative judgments. How should we explain this coincidence? This is what Sharon Street (2006) calls the practical/theoretical puzzle. Some metaethicists can easily solve this puzzle, but not all of them can, Street argues; she takes (...) the puzzle to constitute a specific challenge for normative realism. In this article I elucidate Street's puzzle and outline possible solutions to it, framed in terms of a general strategy for reasoning about coincidences. I argue that the success of Street's challenge crucially depends on how we set the ‘reference class’ of normative judgments that we could have endorsed, assuming realism. I conclude that while the practical/theoretical puzzle falls short of posing a general challenge for normative realism, it can be successful as a selective challenge for specific realist views. (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)

Over the course of human history there appears to have been a global shift in moral values towards a broadly ‘liberal’ orientation. Huemer argues that this shift better accords with a realist than an antirealist metaethics: it is best explained by the discovery of mind-independent truths through intuition. In this article I argue, contra Huemer, that the historical data are better explained assuming the truth of moral antirealism. Realism does not fit the data as well as Huemer suggests, whereas antirealists (...) have underappreciated resources to explain the relevant historical dynamics. These resources include an appeal to socialization, to technological and economical convergences, to lessons learned from history, to changes induced by consistency reasoning and to the social function of moral norms in overcoming some of the cooperation problems that globalizing societies face. I point out that the realist’s explanans has multiple shortcomings, that the antirealist’s explanans has several explanatory virtues, and conclude that the latter provides a superior account of the historical shift towards liberal values.

Moral theorists like Singer and Greene argue that we should discount intuitions about ‘up-close-and-personal’ moral dilemmas because they are more likely than intuitions about ‘impersonal’ dilemmas to be artifacts of evolution. But by that reasoning, it seems we should ignore the evolved, ‘up-close-and-personal’ intuition to save a drowning child in light of the too-new-to-be-evolved, ‘impersonal’ intuition that we need not donate to international famine relief. This conclusion seems mistaken and horrifying, yet it cannot be the case both that ‘up-close-and-personal’ intuitions (...) are more reliable than ‘impersonal’ intuitions, and vice versa. Thus, Singer’s evolutionary debunking argument proves too much, and should not be taken seriously. However, Singer’s debunking argument is typical of an entire class of arguments that seeks to debunk normative principles by reference to evolution. This entire class of argument, I argue, therefore also proves too much to be taken seriously. (shrink)

This paper defends the view that in a certain sense evidence is normative. Neither a bit of evidence nor the fact that it is evidence for a certain proposition is a normative fact, but it is still the case that evidence provides normative reason for belief.

Two important objections will be discussed, one from A. Steglich-Petersen on (...) whether having evidence is sufficient for having a normative reason for belief and another one from S. Street.

Why does God allow evil? One hypothesis is that God desires the existence and activity of free creatures but He was unable to create a world with such creatures and such activity without also allowing evil. If Molinism is true, what probability should be assigned to this hypothesis? Some philosophers claim that a low probability should be assigned because there are an infinite number of possible people and because we have no reason to suppose that such creatures will choose one (...) way rather than another. Arguments like this depend on the principle of indifference. But that principle is rejected by most philosophers of probability. Some philosophers claim that a low probability should be assigned because doing otherwise violates intuitions about freewill. But such arguments can be addressed through strategies commonly employed to defend theories with counterintuitive results across ethics and metaphysics. (shrink)

If moral properties lacked causal powers, would moral skepticism be true? I argue that it would. Along the way I respond to various arguments that it would not.

Robert Nozick's experience machine thought experiment is often considered a decisive refutation of hedonism. I argue that the conclusions we draw from Nozick's thought experiment ought to be informed by considerations concerning the operation of our intuitions about value. First, I argue that, in order to show that practical hedonistic reasons are not causing our negative reaction to the experience machine, we must not merely stipulate their irrelevance (since our intuitions are not always responsive to stipulation) but fill in the (...) concrete details that would make them irrelevant. If we do this, we may see our feelings about the experience machine becoming less negative. Second, I argue that, even if our feelings about the experience machine do not perfectly track hedonistic reasons, there are various reasons to doubt the reliability of our anti-hedonistic intuitions. And finally, I argue that, since in the actual world seeing certain things besides pleasure as ends in themselves may best serve hedonistic ends, hedonism may justify our taking these other things to be intrinsically valuable, thus again making the existence of our seemingly anti-hedonistic intuitions far from straightforward evidence for the falsity of hedonism.

Empirical research into moral decision-making is often taken to have normative implications. For instance, in his recent book, Greene (2013) relies on empirical findings to establish utilitarianism as a superior normative ethical theory. Kantian ethics, and deontological ethics more generally, is a rival view that Greene attacks. At the heart of Greene’s argument against deontology is the claim that deontological moral judgments are the product of certain emotions and not of reason. Deontological ethics is a mere rationalization of these emotions. (...) Accordingly Greene maintains that deontology should be abandoned. This paper is a defense of deontological ethical theory. It argues that Greene’s argument against deontology needs further support. Greene’s empirical evidence is open to alternative interpretations. In particular, it is not clear that Greene’s characterization of alarm-like emotions that are relative to culture and personal experience is empirically tenable. Moreover, it is implausible that such emotions produce specifically deontological judgments. A rival sentimentalist view, according to which all moral judgments are determined by emotion, is at least as plausible given the empirical evidence and independently supported by philosophical theory. I therefore call for an improvement of Greene’s argument. (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)

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)

I believe most acts of human procreation are immoral, and I believe this despite also believing in the truth of moral particularism. In this paper I explain why. I argue that procreative acts possess numerous features that, in other contexts, seem typically to operate with negative moral valences. Other things being equal this gives us reason to believe they will operate negatively in the context of procreative acts as well. However, most people’s intuitions represent procreative acts to be morally permissible (...) in most circumstances. Given moral particularism, this would normally be good evidence that procreative acts are indeed morally permissible and that the features that operate negatively elsewhere, simply do not do so in the context of procreative acts in particular. But I argue that we have no good reason to think our intuitions about the ethics of human procreation are accurate. Our most reliable source of insight into the ethics human procreative acts are not our intuitions those acts themselves, but our intuitions about the typical moral valences of the features such acts possess. If that is correct, then acts of human procreation are most likely wrong. (shrink)

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

In Being Realistic About Reasons,T.M. Scanlon develops a non-naturalistic realist account of normative reasons. A crucial part of that account is Scanlon’s contention that there is no deep epistemological problem for non-naturalistic realists, and that the method of reflective equilibrium suffices to explain the possibility of normative knowledge. In this critical notice we argue that this is not so: on a realist picture, normative knowledge presupposes a significant correlation between distinct entities, namely between normative beliefs and normative facts. This correlation (...) calls for an explanation. We show that Scanlon does not have the resources to offer such an explanation. (shrink)

Sharon Street defines her constructivism about practical reasons as the view that whether something is a reason to do a certain thing for a given agent depends on that agent’s normative point of view. However, Street has also maintained that there is a judgment about practical reasons which is true relative to every possible normative point of view, namely constructivism itself. I show that the latter thesis is inconsistent with Street’s own constructivism about epistemic reasons and discuss some consequences of (...) this incompatibility. (shrink)

In a methodological milieu characterized by efforts to bring the methods of philosophy closer to the methods of the sciences, one can find, with increasing regularity, meta-ethical arguments relying on scientific theory or data. The received view appears to be that, not only is it implausible to think that a scientific vindication of a non-mentalist moral semantics will be forthcoming but that evidence from a variety of sciences threatens to undermine non-mentalist views. My aim is to push back against this (...) apparent consensus. The well-established phenomenon whereby moral judgments influence our attributions of putatively purely descriptive properties has come to be known as the Knobe Effect. Joshua Knobe has attempted to explain this surprising phenomenon by arguing that our folk psychological judgments are partially constituted by moral judgments. Drawing on an argument originally offered by Moore, I argue that if some instantiation of Knobe’s explanatory strategy is accurate, we have good reason to believe that mentalist moral semantics are untenable.

Abstract Street has argued that the meta-ethical realist is faced with a dilemma. Either evolutionary forces have had a distorting influenced on our ability to track moral properties or evolutionary forces influenced our beliefs in the direction of tracking moral properties. Street argues that if the realist accepts the first horn of the dilemma, the realist must accept implausible skepticism regarding moral beliefs. If the realist accepts the second horn of the dilemma, the realist owes an explanation of the fitness (...) producing nature of moral beliefs. As Street establishes the dialectic, the anti-realist’s explanation is better. I will argue that Street’s first horn is question begging then I will grasp the second horn of the dilemma and argue that only the realist can explain the role of moral beliefs in our evolutionary history. My argument will take the form of a dilemma. For our evaluative judgments to be fitness conducive, they must be responsive to the right sort of external world properties. The non-reductive realist can provide such a set of properties. On the first horn of the dilemma, the anti-realist cannot. The realist, unlike the anti-realist, can explain why our evaluative judgments are fitness conducive. The realist has won the explanatory battle. On the second horn of the dilemma, the anti-realist can provide a set of non-normative external world properties that our evaluative attitudes are responsive to. In doing so, the anti-realist has provided the heretofore-missing component of the reductive realist’s project. Again, the realist has won. (shrink)

The debate over the grounds of full moral status relies heavily on the “method of cases.” In the method of cases intuitions about particular cases are taken as evidence for philosophical theories. Much in the debate over the grounds of full moral status turns on our intuitions regarding the moral status of individuals with intellectual disability. This paper argues that the intuitions of those in close personal relationships with individuals with intellectual disability are more reliable than the intuitions of those (...) who lack such a relationship. When theorizing about full moral status, we should privilege the intuitions of those who have a close personal relationship with an individual with intellectual disability. (shrink)

This essay addresses recent claims about the compatibility of the sociobiological theory of reciprocal altruism with standard Western formulations of the Golden Rule. Derek Parfit claims that the theory of reciprocal altruism teaches us to be “reciprocal altruists,” who benefit only those people from whom we can reasonably expect benefits in the future. The Golden Rule, on the other hand, teaches us to benefit anyone regardless of their intention or ability to return the favor, or as Parfit puts it, the (...) Golden Rule teaches us to be “suckers.” I argue that this distinction is founded on a misconception of the nature of the theory of reciprocal altruism, which is sociobiological as opposed to moral, and that this distinction accordingly confuses is with ought. Sociobiological theories may explain underlying psychological motivations in individuals (and perhaps even in populations), but these theories do not prescribe any sort of moral behavior. Furthermore, the theory of reciprocal altruism does not imply mental states of which agents are aware. The unconscious motivations assumed by this theory are in fact compatible with certain formulations of the Golden Rule; I will accordingly argue for the view that certain words with moral content related to the Golden Rule—such as “altruism” and “selfishness”—exist only insofar as they are social tools, which can further the self-interests of an individual in any group.

Suppose that there are objective normative facts and our beliefs about such facts are by-and-large true. How did this come to happen? This is the reliability challenge to normative realism. As has been recently noted, the challenge also applies to expressivist “quasi-realism”. I argue that expressivism is useful in the face of this challenge, in a way that has not been yet properly articulated. In dealing with epistemological issues, quasi-realists typically invoke the desire-like nature of normative judgments. However, this is (...) not enough to prevent the reliability challenge from arising, given that quasi-realists also hold that normative judgments are truth-apt beliefs. To defuse this challenge, we need to isolate a deeper sense in which normative thought is not representational. I propose that we rely on the negative functional thesis of expressivism: normative thought does not have the function of tracking normative facts, or any other kind of facts. This thesis supports an argument to the effect that it is misguided to expect an explanation of our access to normative facts akin to the explanations available in regions of thought that have a tracking function. We should be content with explanations of our reliability that take for granted certain connections between our psychology and the normative truths. (shrink)

When making moral judgments, people are typically guided by a plurality of moral rules. These rules owe their existence to human emotions but are not simply equivalent to those emotions. And people’s moral judgments ought to be guided by a plurality of emotion-based rules. The view just stated combines three positions on moral judgment: [1] moral sentimentalism, which holds that sentiments play an essential role in moral judgment,1 [2] descriptive moral pluralism, which holds that commonsense moral judgment is guided by (...) a plurality of moral rules2, and [3] prescriptive moral pluralism, which holds that moral judgment ought to be guided by a plurality of moral rules. In what follows, we will argue for all three positions. We will not present a comprehensive case for these positions nor address many of the arguments philosophers have developed against them. What we will try to show is that recent psychological work supports sentimentalist pluralism in both its descriptive and prescriptive forms. (shrink)

In Sect. 1 I explain Mooreanism and then ethical Mooreanism. In Sect. 2 I argue for ethical Mooreanism by noting a number of important epistemic parities that hold between certain moral truths and standard Moorean facts. In Sect. 3 I (...) defend ethical Mooreanism against the objection that moral propositions are too epistemically dissimilar to standard Moorean facts to count as Moorean truths. (shrink)

The self-ownership thesis asserts, roughly, that agents own their minds and bodies in the same way that they can own extra-personal property. One common strategy for defending the self-ownership thesis is to show that it accords with our intuitions about the wrongness of various acts involving the expropriation of body parts. We challenge this line of defense. We argue that disgust explains our resistance to these sorts of cases and present results from an original psychological experiment in support of this (...) hypothesis. We argue further that learning that disgust is responsible for pro-self-ownership intuitions should reduce our confidence in those intuitions. After considering and rejecting some prominent “debunking” arguments predicated on disgust’s evolutionary history, we provide alternative reasons for thinking that disgust is not a reliable source of moral judgments. Rejecting the reliability of disgust as a mechanism for producing moral beliefs coheres with our considered judgments about the general kinds of considerations that are morally relevant and a range of particular moral problems.

Imagine that an anthropologist returns from her study of a group of people and reports the following:They refuse to kill one person even to avert the death of all involved—including that one person;They won’t directly push someone to his death to save the lives of five others, but they will push a lever to kill him to save five others;They punish transgressors because it feels right, even when they expect the punishment to cause far more harm than good—and even when (...) the harm done by the punishment exceeds the harm done by the transgression being punished.The anthropologist’s report might lead us to conclude that these people are at least confused, and perhaps even dangerous.Here’s some bad news.

If our ordinary moral judgments are to do the strategic work Greene wants them to do, he needs to endorse fullfledged Sidgwickian self-effacement for at least some areas of micro-level decision making. By the lights of some of Greene’s own arguments, people must accept the correctness—and not simply the usefulness—of the relevant intuitions in their personal conduct to satisfy utilitarian standards. I argue that removing utilitarian reasoning from micro-level decision making is consistent with Greene’s preferred strategy of using utilitarianism as a Bcommon currency^ for resolving moral conflict at the institutional level. To clarify upfront: the aim of this paper is to offer an internal criticism rather than to defend (e.g.,) the relevant empirical research, utilitarianism, self-effacement, and so on. I’m making an argument about where Greene’s own psychological and philosophical commitments should take him. (shrink)

This article explores the respective roles that medical and technological cognitive enhancements, on the one hand, and the moral and epistemic virtues traditionally understood, on the other, can play in enabling us to lead the good life. It will be shown that neither the virtues nor cognitive enhancements (of the kind we have access to today or in the foreseeable future) on their own are likely to enable most people to lead the good life. While the moral and epistemic virtues (...) quite plausibly are both necessary and sufficient for the good life in theory, virtue ethics is often criticised for being elitist and unachievable in practice for the vast majority. Some cognitive enhancements, on the other hand, might be necessary for the good life but are far from sufficient for such an existence. Here it will be proposed that a combination of virtue and some cognitive enhancements is preferable. (shrink)

Both realist and anti-realist accounts of natural kinds possess prima facie virtues: realists can straightforwardly make sense of the apparent objectivity of the natural kinds, and anti-realists, their knowability. This paper formulates a properly anti-realist account designed to capture both merits. In particular, it recommends understanding natural kinds as ‘categorical bottlenecks,’ those categories that not only best serve us, with our idiosyncratic aims and cognitive capacities, but also those of a wide range of alternative agents. By endorsing an ultimately subjective (...) categorical principle, this view sidesteps epistemological difficulties facing realist views. Yet, it nevertheless identifies natural kinds that are fairly, though not completely, stance-independent or objective. (shrink)

In this paper, I distinguish between two error theories of morality: one couched in terms of truth ; the other in terms of justification. I then present two arguments: the Poisoned Presupposition Argument for ET1; and the Evolutionary Debunking Argument for ET2. I go on to show how assessing these arguments requires paying attention to empirical moral psychology, in particular, work on folk metaethics. After criticizing extant work, I suggest avenues for future research.

Recent debate in metaethics over evolutionary debunking arguments against morality has shown a tendency to abstract away from relevant empirical detail. Here, I engage the debate about Darwinian debunking of morality with relevant empirical issues. I present four conditions that must be met in order for it to be reasonable to expect an evolved cognitive faculty to be reliable: the environment, information, error, and tracking conditions. I then argue that these conditions are not met in the case of our evolved (...) faculty for moral judgement. (shrink)

Adaptationist accounts of morality attempt to explain the evolution of morality in terms of the selective advantage that judging in moral terms secured for our ancestors (e.g. Ruse 1998; Joyce 2006; Street 2006). So-called by-product explanations of morality have been presented as an alternative to adaptationist accounts (e.g. Prinz 2009; Ayala 2010; cf. Darwin 2004/1871). In assessing the relationship between adaptationist and by-product accounts, care must be taken to distinguish several related but importantly different notions: innateness, adaptation, exaptation, spandrel, and (...) by-product.

Introduction: characterizing ethical realismIt is useful to begin a survey of recent work on ethical realism with a look at current disputes over what makes a theory of ethics count as ‘realist’ in the first place. Nearly all characterizations of ethical realism include some version of the following two core claims: Ethical discourse is assertoric and descriptive: ethical claims purport to state ethical facts by attributing ethical properties to people, actions, institutions, etc., and are thus true or false depending on (...) whether their descriptions of things are accurate or not . 1 At least some ethical claims, when literally construed, are true in the above sense.Sayre-McCord maintains that these two conditions are necessary and sufficient to characterize ethical realism; others argue that further conditions must be added to yield ethical realism, or at least ‘paradigmatic’ or ‘robust’ ethical realism. Before turning to that, however, it is worth noting that some have recently denied that the above two conditions are even necessary for ethical realism. In probing new work on metaethical taxonomy, Miller argues that the core of ethical realism is simply the metaphysical commitment to objective ethical properties and facts, which is strictly independent of the semantic claims above. If one holds that there are objective facts about the wrongness of slavery, for example, then one ought to count as an ethical realist regardless of whatever views one might hold about the semantics of the contingent forms of discourse that have evolved among language users. Even if our ethical discourse turns out primarily to express conative states ), or all moral claims turn out to be false because …. (shrink)

I begin by distinguishing two general approaches to metaethics and ontology. One in effect puts our experience as engaged ethical agents on hold while independent metaphysical and epistemological inquiries, operating by their own lights, deliver metaethical verdicts on acceptable interpretations of our ethical lives; the other instead keeps engaged ethical experience in focus and allows our reflective interpretation of it to shape our metaphysical and epistemological views, including our ontology. While the former approach often leads to deflationary views, the latter (...) may lead us to enrich our metaethical picture as needed to capture robust objectivity and categorical normative authority for ethics. Assuming, as I have argued elsewhere, that this requires positing irreducibly evaluative or normative properties and facts, the question I take up here is what ontological implications this has. I argue against quietist non-naturalist views, which maintain that positing such properties and facts either has no ontological implications or has only domain-specific ontological implications that likewise imply nothing about what the world contains. Against these views, I advocate a worldly, dual-aspect view, locating irreducibly evaluative or normative properties as features of relevant worldly things. But while I have previously defended this view as a form of non-naturalism, I here explore the possibility of instead seeing it as a new, more expansive form of naturalism—what might be called “Non-Scientistic Naturalism”—inspired by parallel attempts in the philosophy of mind to accommodate irreducibly phenomenal properties within a more expansive physicalism.

What implications, if any, does evolutionary biology have for metaethics? Many believe that our evolutionary background supports a deflationary metaethics, providing a basis at least for debunking ethical realism. Some arguments for this conclusion appeal to claims about the etiology of the mental capacities we employ in ethical judgment, while others appeal to the etiology of the content of our moral beliefs. In both cases the debunkers’ claim is that the causal roles played by evolutionary factors raise deep epistemic problems (...) for realism: if ethical truths are objective or independent of our evaluative attitudes, as realists maintain, then we lose our justification for our ethical beliefs once we become aware of the evolutionary shaping of our ethical capacities or beliefs, which would not have disposed us reliably to track independent ethical truths; realism, they claim, thus saddles us with ethical skepticism. I distinguish and spell out various evolutionary debunking arguments along these lines and argue that they all fail: the capacity etiology argument fails to raise any special or serious problem for realism, and the content etiology arguments all rely on strong explanatory claims about our moral beliefs that are simply not supported by the science unless it is supplemented by philosophical claims that just beg the question against realism from the start. While the various debunking arguments do bring out some interesting commitments of ethical realism, and even raise some good challenges as realists develop positive moral epistemologies, they fall far short of their debunking ambitions.

In this paper, I propose a solution to a challenge formulated by Judith Jarvis Thomson: We have to explain why the moral asymmetry between doing and allowing harm is a deep feature of our moral thinking. In a nutshell, my solution is this: It could not be otherwise. Accepting the asymmetry is indispensable for the construction and maintenance of stable moral communities. -/- My argument centrally involves mental resource management. Moral communities depend on their members’ commitment to moral norms. And, (...) I argue, community members can only be committed to these norms in the required ways without overextending their mental resources if morality contains the doing/allowing asymmetry. -/- This has two noteworthy implications. Firstly, we can and should stop discussing the asymmetry in normative ethics and, instead, regard it as “moral axiom” we cannot but accept. Secondly, even consequentialists have to accept the asymmetry but, by doing so, their view loses part of its intuitive appeal. Lastly, I turn to an objection. One might think that my indispensability argument confuses issues in moral psychology with issues in normative ethics. I reject the objection on broadly pragmatist grounds. (shrink)

Is the cultural evolution of morality fairly contingent? Could cultural evolution have easily led humans to moral norms and judgments that are mostly false by our present lights? If so, does it matter philosophically? Yes, or so we argue. We empirically motivate the contingency of cultural evolution and show that it makes two major philosophical contributions. First, it shows that moral objectivists cannot explain the reliability of our moral judgments and thus strengthens moral debunking arguments. Second, it shows that the (...) reliability of our moral judgments is evidence for theism over metaphysical naturalism. (shrink)
