In metaethics, empirical approaches are not just complementary to, but continuous with, traditional approaches to the subject. This chapter addresses traditional and empirical approaches to metaethics. It discusses how empirical approaches have been brought to bear on some central metaethical questions. The chapter illustrates not just the diversity of topics within metaethics itself but also the diversity of empirical methods and approaches that philosophers and psychologists working on these topics are using. The debate (...) between internalists and externalists is a debate concerning the psychology of moral judgment, but also a debate about our concept of moral judgment. As such, it has implications for other metaethical debates. Antirealists such as relativists and noncognitivists often defend internalism, and argue that their views are best equipped to explain the link between moral judgment and motivation. (shrink)

What contribution can the empirical sciences make to metaethics? This paper outlines an argument to a particular metaethical conclusion - that moral judgments are epistemically unjustified - that depends in large part on a posteriori premises.

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)

In this paper, I review recent attempts by experimental philosophers and psychologists to study folk metaethics empirically and discuss some of the difficulties that researchers face when trying to construct the right kind of research materials and interpreting the results that they obtain. At first glance, the findings obtained so far do not look good for the thesis that people are everywhere moral realists about every moral issue. However, because of difficulties in interpreting these results, I argue that better (...) research is needed to move the debate forward. (shrink)

Philosophers have in recent years displayed an increasing interest in investigating folk metaethical beliefs using rigorous empirical methods. Taken together, these studies put significant pressure on many philosophical theories that depend on the truth of folk moral objectivism, the view that the folk see morality as objectively grounded. Frequently included among the target of criticism is Mackie’s error theory, or more specifically the conceptual claim thereof. Finding this criticism misplaced, Benjamin Fraser tries to exonerate error theory from such accusation (...) by distinguishing different senses of objectivity. In this paper, I show why Fraser’s strategy is not successful so that the pressure empirically brought upon classical error theory is genuine. However, I also argue that even on the new picture suggested by experimental studies, the folk still entertain erroneous beliefs, which, when coupled with plausible metasemantic assumptions and further empirical support, should warrant an error theory after all, though not in its classical form.

Even if we know all relevant descriptive facts about an act, we can still be uncertain about its moral acceptability. Most literature on how to act under such normative uncertainty operates on moral realism, the metaethical view that there are objective moral facts. Lay people largely report anti-realist intuitions, which poses the question of how these intuitions affect their interpretation and handling of normative uncertainty. Results from two quasi-experimental studies (total N = 365) revealed that most people did not interpret (...) normative uncertainty as referring to objective moral facts but rather as uncertainty regarding one’s own view, uncertainty regarding the culturally accepted view or as the result of ambivalence. Especially the anti-realist majority of participants interpreted normative uncertainty different to how it is described in the literature on choice under normative uncertainty. Metaethical views were also associated with lay peoples’ choice of uncertainty reduction strategies and with assumptions about the intended aim of such strategies. The current findings suggest that empirical investigations of normative uncertainty might benefit from considering folk metaethical pluralism, as the lay public largely disagrees with the metaethical assumptions underlying the current discourse on choice under normative uncertainty.

Prinz claims that empirical work on emotions and moral judgement can help us resolve longstanding metaethical disputes in favour of simple sentimentalism. I argue that the empirical evidence he marshals does not have the metaethical implications he claims: the studies purporting to show that having an emotion is sufficient for making a moral judgement are tendentiously described. We are entitled to ascribe competence with moral concepts to experimental subjects only if we suppose that they would withdraw their moral (...) judgement on learning that they were fully explained by hypnotically induced disgust. Genuine moral judgements must be reason-responsive. To capture the reason-responsiveness of moral judgement, we must turn to either neo-sentimentalism or to a non-sentimentalist metaethics, either of which is fully compatible with the empirical evidence Prinz cites.

Are there things that are objectively right, wrong, good, bad, etc.: moral properties that are had independently of what we ourselves, our culture, God or any other subjects think about them? Philosophers have traditionally addressed this question from the “armchair.” In recent years, however, more and more participants of the debate have begun to appeal to evidence from science as well. This thesis examines such novel approaches. In particular, it asks what the empirical sciences can contribute to the moral (...) realism/anti-realism debate. My first aim is to show that it is possible for scientific evidence to bear on the question of the existence of objective moral properties. To see whether such contributions are also likely, I will then consider various prominent particular realist and anti-realist arguments: arguments based on hypotheses about ordinary people’s moral experience, the prevalence and persistence of moral disagreement, the evolution of morality, the relation of moral judgements to emotions, and the projection of values. If true, some of these empirical hypotheses would have metaethical implications. The problem with the arguments is, however, that the available scientific evidence does not support, or even contradicts these hypotheses. Only in ways other than have been suggested so far does the evidence considered in this thesis allow for a substantial metaethical conclusion. Finally, I will show that the relation between the empirical sciences and the question of the reality of moral values is actually much closer than commonly assumed. Not only do scientific hypotheses bear on metaethics, metaethical issues bear on the investigation of scientific hypotheses about morality as well. In order to further increase our understanding of what morality is, philosophers and scientists should therefore join forces and work together more closely than they have done so far. (shrink)

Ethical naturalism is sometimes accused of problematic metaphysics or epistemology. Some argue that naturalists rely on concepts of ‘nature’ indefensible in the light of modern evolutionary biology. There is also an epistemological worry that has been raised recently that strong normative evaluation, such as meaning in human life, is empirically inaccessible or even in conflict with what we know in scientific contexts. While the critics have targeted Aristotelian and Neo-Aristotelian views, I will appeal to an argument from the Neo- Confucian (...) Zhu Xi as one potential way that we can respond to skeptics. If we can know that human beings are capable of moral goodness, and it is comprehensible for us to take moral goodness as a final or unifying goal of our lives, then we can respond to the skeptical objections which allege that we cannot sustain rich normative judgments about meaning in life in the face of scientific evidence.

According to non-cognitivism, moral sentences and judgements do not aim to represent how things morally are. This paper presents an empirical argument against this view. We begin by showing that non-cognitivism entails the prediction that after some reflection competent ordinary speakers’ semantic intuitions favor that moral sentences and judgements do not aim to represent how things morally are. At first sight, this prediction may seem to have been confirmed by previous research on folk metaethics. However, a number of (...) methodological worries lead us to doubt this interpretation. We, therefore, conducted a psychological study that alleviates these worries as far as possible. It turned out that competent ordinary speakers’ reflective semantic intuitions dominantly fail to favor that moral sentences do not aim to represent how things morally are. This challenge to non-cognitivism is defended and supplemented by considering deflationary theories of moral truth and middle ground theories in the cognitivism/non-cognitivism debate. (shrink)

Recent empirical work on folk moral objectivism has attempted to examine the extent to which folk morality presumes that moral judgments are objectively true or false. Some researchers report findings that they take to indicate folk commitment to objectivism (Goodwin & Darley, 2008, 2010, 2012; Nichols & Folds-Bennett, 2003; Wainryb et al., 2004), while others report findings that may reveal a more variable commitment to objectivism (Beebe, 2014; Beebe et al., 2015; Beebe & Sackris, 2016; Sarkissian, et al., 2011; (...) Wright, 2018; Wright, Grandjean, & McWhite, 2013; Wright, McWhite, & Grandjean, 2014). However, the various probes that have been used to examine folk moral objectivism almost always fail to be good direct measures of objectivism. Some critics (Beebe, 2015; Pölzler, 2017, 2018) have suggested that the problems with existing probes are serious enough that they should be viewed as largely incapable of shedding any light on folk metaethical commitments. Building upon the work of Justin Khoo and Joshua Knobe (2018), I argue that many of the existing probes can be seen as good measures of the extent to which people think that the truth of one moral judgment excludes the possibility that a judgment made by a disagreeing party is also true and that the best explanation of the findings obtained using these measures is significant folk support for indexical moral relativism—the view that the content of moral judgments is context-sensitive. If my thesis is correct, many contemporary moral philosophers are deeply mistaken about the metaethical contours of folk morality in one very important respect. (shrink)

Presents the results of our study comparing two different approaches (those of Goodwin and Darley 2008, and Sarkissian et al. 2011) to empirically measuring people's belief in moral objectivity. Examines the relationship between belief in moral objectivity and two other metaethical attitudes: belief in moral progress and belief in a just world.

The turn to empirical ethics answers two calls. The first is for a richer account of morality than that afforded by bioethical principlism, which is cast as excessively abstract and thin on the facts. The second is for the facts in question to be those of human experience and not some other, unworldly realm. Empirical ethics therefore promises a richer naturalistic ethics, but in fulfilling the second call it often fails to heed the metaethical requirements related to the (...) first. Empirical ethics risks losing the normative edge which necessarily characterizes the ethical, by failing to account for the nature and the logic of moral norms. I sketch a naturalistic theory, teleological expressivism (TE), which negotiates the naturalistic fallacy by providing a more satisfactory means of taking into account facts and research data with ethical implications. The examples of informed consent and the euthanasia debate are used to illustrate the superiority of this approach, and the problems consequent on including the facts in the wrong kind of way.

Anyone who has taught an introductory ethics course has found themselves having to explain that some important words can be used in different ways. There is the way social scientists talk when they refer to the norms of a Balinese cockfight, the values of early modern scientific culture, and the morality of Bolsheviks. This chapter examines the possibility that the social aspects of morality might tell us something important about what morality must be, and thus inform our metaethics. It (...) reviews a case for a profitable engagement between metaethics and foundational questions about the social world. The chapter summarizes how extant metaethical views might accommodate, and indeed gain support from, the social features of morality. Naturalists are interested in whether moral facts can earn their keep in our scientific worldview by explaining empirical phenomena. More recent work premised on the idea that moral judgment is based on sentiment sees a more limited role for social induction. -/- . (shrink)

Pragmatism is typically understood as a philosophy embedded in scientific inquiry. Thinkers, like Charles Peirce (1877), C.I. Lewis (1923) and Susan Haack (1998) envisioned pragmatism and its scientific inquiry as a method of systematizing our beliefs and acquiring knowledge. They thought that scientific practice and its implied standards, techniques, and values is the only source of hope for scientific and philosophical progress. In this dissertation, I construct a pragmatic approach to the meta-ethical questions of our moral truths, beliefs and principles (...) that proposes a normative systematization of ethics grounded in moral practice, development and experimentation. I argue that maintaining a pragmatic faith in the origination and formation of our moral constitutions will provide us with a realist, cognitivist and objective view of reality subject to the capacities of our human cognition and empirical evidence and not subject to metaphysical and universal methods of reasoning.

This paper makes the case for a revision of contemporary forms of political realism in political theory. I argue that contemporary realists have gone awry in increasingly centring their approach around a metaethical claim: that political theory should be rooted in a political form of normativity that is distinct from moral normativity. Several critics of realism have argued that this claim is unconvincing. But I suggest that it is also a counterintuitive starting point for realism, and one unnecessary to avoid (...) the ‘applied morality’ approach to political theory that realists oppose. Instead, realism should be methodologically orientated around what I term ‘empirically constitutive political realities’ - enduring features of real political contexts that are systematically consequential in their normative implications. Realists can persuasively argue that such empirically constitutive political realities must be attended to in political theory-building, and not merely treated as a context in which independently formulated moral theories are simply applied. This framing of realism accords real politics a genuinely foundational theoretical role, but without requiring any contentious metaethical stance about a non-moral political normativity. I explain some methodological implications that follow for realism – in particular the need to prioritise empirically grounded theorisation of real political contexts over abstract and rather essentialist claims about ‘the political’. I also argue that such a framing of realism helps engender a more accurate, less divisive, and more pluralist conception of methodological debates within political theory. (shrink)

Metaethical relativism is the view that whether a moral claim is true depends on the standards endorsed by an individual or society. This view is attractive because it allows one to hold that moral claims can be true or false in an ordinary correspondence sense, without being committed to the view that moral claims state objective facts. But what could it mean to say that a whether a moral claim is true depends on an individual or society’s standards? How could (...) a single claim be true or false in an ordinary sense, and yet be true for some people while false for others? This thesis defends a certain answer to this question: metaethical truth relativism. Metaethical relativists have historically endorsed a different view: content relativism, which is the view that the semantic contents of moral claims vary across contexts of use. However, semanticists working outside metaethics have recently shown that an alternative exists, namely truth relativism: the view that the truth values of moral contents vary across contexts. Metaethicists have been slow to investigate the significance of this discovery. This is surprising, because truth relativism appears to avoid some of the most influential objections to content relativist views. Thus, this development in semantics appears to offer an exciting new direction for research on relativism in metaethics. The scope of this thesis is not narrowly semantic, however. Questions in moral semantics often interconnect with questions in substantive metaethics, and the question of whether ethical thought and talk is semantically relativistic is no exception. Therefore, while the core of the this thesis focuses on moral semantics, it also contains a fair amount of substantive metaethical material, located primarily in the first and final chapters. The plan of the thesis is as follows. Chapters 1 & 2 begin with a discussion of the most historically influential argument for metaethical relativism: the argument from disagreement. Chapter 1 discusses an epistemic version of this argument, but concludes that this version provides only limited evidence for relativism. However, chapter 2 introduces a different version of the argument, with a more semantic focus, and begins to make the case that this argument provides evidence not only for metaethical relativism broadly construed, but for truth relativism in particular. The broad strokes of this argument are that there can be moral disagreements which are faultless and furthermore that only truth relativism can vindicate the sense that these are genuine disagreements, rather than mere differences of opinion. Chapter 2 presents empirical evidence for the claim that putative moral disagreements can be faultless. Chapters 3 and 4 then take a deep dive into the topic of disagreement. Chapter 3 develops a positive account of disagreement which is available only to truth relativists. And chapter 4 advances detailed arguments against contextualist accounts of disagreement. Chapters 3 and 4 together thus defend in detail the claim that truth relativism can, while content relativism cannot, account for the sense that there is genuine disagreement in the relevant cases. Chapters 2 through 4, therefore, form a single long argument for truth relativism. They show that there is a compelling argument for relativism broadly construed, and that deep analysis of the issues surrounding this argument favour truth relativism over content relativism. Chapter 5 zooms back out to the broader metaethical landscape, discussing two remaining objections to relativism. The first objection is that relativism has objectionably subjectivistic implications, and the second is that moral standards cannot helpfully be understood as determined by societies. In the course of responding to these objections, natural opportunities to flesh out the substantive metaethical commitments of the theory will arise. And this will set us up to conclude with a brief comparison of truth relativism with some of the other main options in the space of substantive metaethical theory. (shrink)

This dissertation is an investigation into the ground of moral objectivity. My preliminary claim is that in order to be objective, moral properties must be real properties. The following question is, what kind of properties are moral properties? A number of recent philosophers have argued that moral properties are natural properties. ''Natural" in this context means " open to investigation and discovery by the senses or by empirical science." The natural properties proposed in the recent literature are connected to (...) the property of human well-being. The main project of my dissertation is to show that natural properties are not adequate as the foundation for moral objectivity, because there is no necessary connection between any natural properties and moral properties. Another answer to the question of what kind of properties moral properties are is that they are supernatural properties. "Supernatural" in this context means "not open to investigation and discovery by the senses, or by empirical science." It is my argument that a singular supernatural being who created the world and has particular ideas about what sorts of people/actions/states of affairs are good and bad or right and wrong is the only sufficient ground for moral objectivity. Given such a being, moral properties will be real and objective. They will also be moral properties, since the originator of these properties confers value on them. Using and expanding on work in Divine Command Theory, especially that of Robert M. Adams, my original contribution to this discussion is to propose that moral properties are relational properties. The relationship is between persons, actions, states of affairs, etc., in the physical world, and the ideas, desires, character, or commands of the supernatural being. An important limitation of my dissertation project is that I do not consider any practical issues such as "How do we know whether God exists?", "How would God communicate the content of morality to us?", or "What is God like?" These are important and worthwhile questions, but are not a part of my present investigation. (shrink)

A critical survey of various positions on the nature, use, possession, and analysis of normative concepts. We frame our treatment around G.E. Moore’s Open Question Argument, and the ways metaethicists have responded by departing from a Classical Theory of concepts. In addition to the Classical Theory, we discuss synthetic naturalism, noncognitivism (expressivist and inferentialist), prototype theory, network theory, and empirical linguistic approaches. Although written for a general philosophical audience, we attempt to provide a new perspective and highlight some underappreciated (...) problems about normative concepts. (shrink)

Th e present article reports a series of experiments designed to extend the empirical investigation of folk metaethical intuitions by examining how different kinds of ethical disagreement can impact attributions of objectivity to ethical claims.

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.

Lay persons may have intuitions about morality's objectivity. What do these intuitions look like? And what are their causes and consequences? In recent years, an increasing number of scholars have begun to investigate these questions empirically. This article presents and assesses the resulting area of research as well as its potential philosophical implications. First, we introduce the methods of empirical research on folk moral objectivism. Second, we provide an overview of the findings that have so far been made. Third, (...) we raise a number of methodological worries that cast doubt upon these findings. And fourth, we discuss ways in which lay persons' intuitions aboutmoral objectivity may bear on philosophical claims. (shrink)

Many philosophers assume that philosophical theories about the psychological nature of moral judgment can be confirmed or disconfirmed by the kind of evidence gathered by natural and social scientists (especially experimental psychologists and neuroscientists). I argue that this assumption is mistaken. For the most part, empirical evidence can do no work in these philosophical debates, as the metaphorical heavy-lifting is done by the pre-experimental assumptions that make it possible to apply empirical data to these philosophical debates. For the (...) purpose of this paper, I emphasize two putatively empirically-supported theories about the psychological nature of moral judgment. The first is the Sentimental Rules Account, which is defended by Shaun Nichols. The second is defended by Jesse Prinz, and is a form of sentimentalist moral relativism. I show that both of the arguments in favour of these theories rely on assumptions which would be rejected by their philosophical opponents. Further, these assumptions carry substantive moral commitments and thus cannot be confirmed by further empirical investigation. Because of this shared methodological assumption, I argue that a certain form of empirical moral psychology rests on a mistake. (shrink)

This volume examines the psychological basis of moral judgments and what theories of concepts apply to moral ones. It considers what mental states not only influence but also constitute our moral concepts and judgments by combining philosophical reasoning and empirical insights from the fields of moral psychology, cognitive science, evolutionary psychology, and neuroscience. On this basis, Park proposes a novel pluralistic theory of moral concepts which includes three different cognitive structures and emotions. Thus, our moral judgments are a hybrid (...) that express both cognitive and conative states. -/- In part through analysis of new empirical data on moral semantic intuitions, gathered via cross-cultural experimental research, Park draws on this to reveal that the referents of individuals’ moral judgments and concepts vary across time, contexts, and groups. Due to this, he contends for moral relativism, where moral judgments cannot be universally true across time and location but only relative to groups. -/- This text will benefit researchers, academics, and educators with an interest in cognitive science, moral theory, philosophy of psychology, and moral psychology more broadly. Those interested in ethics, applied social psychology, and moral development will also benefit from the volume. (shrink)

Moral realists often assume that folk intuitions are predominantly realist, and they argue that this places the burden of proof on antirealists. More broadly, appeals to intuition in metaethics typically assume that folk judgments are generally consistent across individuals, such that they are at least predominantly something, if not realist. A substantial body of empirical work on moral objectivism has investigated these assumptions, but findings remain inconclusive due to methodological limitations. Objectivist judgments classify individuals into broad categories of (...) realism and antirealism, but they do not address more specific conflicts in the metaethical literature between different types of realism and antirealism, such as between nonnaturalism and divine command theory, or between noncognitivism and error theory. Further, the data currently show that the folk are objectivists about some moral claims but not others, raising questions that have not been addressed in previous studies about how much of the moral domain is judged to be objective, and about how endorsements of different types of realism and antirealism are distributed among different types of moral claims. Here, I present a new survey that addresses these limitations. The results challenge both of the empirical assumptions identified above, with important implications for metaethical methodology.

Arguably, one of the most exciting recent advances in moral philosophy is the ongoing scientific naturalization of normative ethics and metaethics, in particular moral psychology. A relatively neglected area in these improvements that is centrally important for developing a scientifically based naturalistic metaethics concerns the nature and acquisition of successful moral agency. In this paper I lay out two examples of how empirically based findings help us to understand and explain some cases of successful moral agency. These are (...) research in moral internalization and aggression management. Using these examples, I sketch some lessons for investigating successful moral learning and moral action. My proposal reflects a common theme in scientifically based philosophy generally: the shift from the armchair methods of analyzing concepts and finding a priori foundations, the enterprise of first philosophy, to an effort to study the phenomena themselves, using empirical findings and theories to answer philosophical questions about these phenomena, an endeavor recently characterized as second philosophy.

In this paper, I examine six arguments concerning or making use of empirical psychological evidence in metaethics and normative ethics. Generally speaking, I find that the ambitious ones fail and the more modest ones ought to moderate their conclusions further.

Many metaethicists agree that as ordinary people experience morality as a realm of objective truths, we have a prima facie reason to believe that it actually is such a realm. Recently, worries have been raised about the validity of the extant psychological research on this argument’s empirical hypothesis. Our aim is to advance this research, taking these worries into account. First, we propose a new experimental design for measuring folk intuitions about moral objectivity that may serve as an inspiration (...) for future studies. Then we report and discuss the results of a survey that was based on this design. In our study, most of our participants denied the existence of objective truths about most or all moral issues. In particular, many of them had the intuition that whether moral sentences are true depends both on their own moral beliefs and on the dominant moral beliefs within their culture. This finding suggests that the realist presumptive argument may have to be rejected and that instead anti-realism may have a presumption in its favor. (shrink)

The phenomenon of “dirty hands” is typically framed as an issue for normative or applied ethical consideration—for example, in debates between consequentialism and nonconsequentialism, or in discussions of the morality of torture or political expediency. By contrast, this paper explores the metaethical dimensions of dirty-hands situations. First, empirically-informed arguments based on scenarios of moral dilemmas involving metaethical aspects of dirty hands are marshaled against the view that “ought implies can.” Second, a version of moral realism is conjoined with a version (...) of value-pluralism that charitably accommodates and explains the central features of the phenomenology related to dirty hands. It is not simply that agents are or are not justified in getting their hands dirty (les mains sales); rather, in certain situations, it is the nature of the moral domain itself to be intractably messy (le sale monde), such that dirty hands are unavoidable. The paper concludes by considering some important normative and psychological implications of this view. (shrink)

The field of metaethics, the branch of moral philosophy that examines the nature and status of morality, is rich in theoretical diversity. Nonetheless, a majority of professional philosophers embrace a subset of theories that affirm the existence of objective moral facts. I suggest that this may be related to the very method that philosophers use to construct metaethical theories. This method involves analyzing how ordinary people think and argue about morality. Analysis of ordinary moral discourse is meant to reveal (...) common platitudes (or truisms) about the nature of morality itself, including the platitude that morality trades in objective moral facts. But do philosophers investigate ordinary moral discourse in any systematic way? How do they arrive at such platitudes? On what grounds are they jusified? In this paper, I critically examine these questions, and argue that a) any such platitudes need to be investigated systematically through empirical research, and b) philosophers ought to be engaged in this research themselves.

Versions of internalism have played important roles in metaethics, for example, in defending irrealist options such as emotivism. However, internalism is itself as controversial as the views it is used to defend. Standard approaches to testing the view, such as thought experiments about amoralists, have failed to gain consensus. Michael Huemer offers a defense of internalism of a different kind which he calls the “argument from interpretation.” He presents the argument as one Humeans could embrace, but versions could be (...) accepted by others, including Huemer himself. The argument begins from the assumption that a certain principle of charity is true and knowable a priori. But it can only be known a priori if internalism is true. Hence internalism is true. In this paper I argue that this important argument fails. My main objection makes use of recent work in empirical psychology. Huemer needs the principle of charity to be known a priori. I argue that rather than being an a priori issue, it is an empirical one and that the empirical evidence is strong enough to undermine his argument for internalism. (shrink)

Quine's ethical views typify what might seem to be natural sympathies between empiricism and ethical noncognitivism. LikeAyer, he sees a case for noncognitivism rooted in an epistemic discontinuity between ethics and science. Quine argues that the absence of genuine moral observation sentences, and thus the absence of empirical checkpoints for the resolution of theoretical disputes, renders ethics, as he terms it, “methodologically infirm” However, recent papers in this journal make clear that Quine appears to be voicing mutually incompatible commitments (...) to both noncognitivism and cognitivism. Here I argue that Davidson's theory of interpretation offers promising ways to resolve these tensions. His constructive program fleshes out the implications of Quine's largely destructive critique of intensional semantics and contains a fairly well‐articulated account of evaluative semantics, one which seems to combine cognitivist and noncognitivist elements harmoniously. Moreover, it is argued that Davidson's long‐standing differences with Quine over the epistemological status Quine accords observation sentences with do not undermine Quine's metaethical critique.

Neo-Aristotelian metaethical naturalism is a modern attempt at naturalizing ethics using ideas from Aristotle’s teleological metaphysics. Proponents of this view argue that moral virtue in human beings is an instance of natural goodness, a kind of goodness supposedly also found in the realm of non-human living things. Many critics question whether neo-Aristotelian naturalism is tenable in light of modern evolutionary biology. Two influential lines of objection have appealed to an evolutionary understanding of human nature and natural teleology to argue against (...) this view. In this paper, I offer a reconstruction of these two seemingly different lines of objection as raising instances of the same dilemma, giving neo-Aristotelians a choice between contradicting our considered moral judgment and abandoning metaethical naturalism. I argue that resolving the dilemma requires showing a particular kind of continuity between the norms of moral virtue and norms that are necessary for understanding non-human living things. I also argue that in order to show such a continuity, neo-Aristotelians need to revise the relationship they adopt with empirical science and acknowledge that the latter is relevant to assessing their central commitments regarding living things. Finally, I argue that to move this debate forward, both neo-Aristotelians and their critics should pay attention to recent work on the concept of organism in evolutionary and developmental biology.

The three papers in this dissertation attempt to explore and defend a kind of middle ground with respect to the question of moral objectivity. In the first paper I use the case of disgust to show how not to go about raising skepticism about moral judgment; in doing so, I argue that disgust can be vindicated with an account on which it tracks social contagion as well as physical contamination. Therefore, the question of whether disgust is an appropriate reaction to (...) moral wrongness can sometimes be answered in the affirmative. In the second paper, I use empirical data from anthropology and psychology to argue that moral disagreement makes trouble for the claim that morality is objective, but I don’t reject objectivity entirely— in the third paper I go on to argue that moral relativism best makes sense of a morality that appears to be objective with respect to some questions but not others.

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)

Thick terms and concepts, such as honesty and cruelty, are at the heart of a variety of debates in philosophy of language and metaethics. Central to these debates is the question of how the descriptive and evaluative components of thick concepts are related and whether they can be separated from each other. So far, no empirical data on how thick terms are used in ordinary language has been collected to inform these debates. In this paper, we present the (...) first empirical study, designed to investigate whether the evaluative component of thick concepts is communicated as part of the semantic meaning or by means of conversational implicatures. While neither the semantic nor the pragmatic view can fully account for the use of thick terms in ordinary language, our results do favour the semanticist interpretation: the evaluation of a thick concept is only slightly easier to cancel than semantically entailed content. We further discovered a polarity effect, demonstrating that how easily an evaluation can be cancelled depends on whether the thick term is of positive or negative polarity. (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.

This dissertation examines the psychology of moral judgment and its implications for normative ethics and metaethics. Recent empirical findings in moral psychology, such as the impact of emotions, intuitions, and situational factors on moral judgments, have sparked a debate about whether ordinary moral judgments are systematically error-prone. Some philosophers, such as Peter Singer and Joshua Greene, argue that these findings challenge the reliability of moral intuitions and support more "reasoned", consequentialist approaches over deontological ones. The first part of (...) the dissertation reviews these provocative findings and the philosophical reactions to them, which often invoke the notion of 'moral relevance' - the idea that some factors shaping moral judgments are morally irrelevant. The second part develops a psychological account of moral relevance, drawing on theories of the moral domain, the role of emotions, and models of moral cognition. This account reveals the complex interplay of intuitive and reasoned processes in generating impressions of moral relevance. The final part reevaluates the philosophical discussions in light of this psychological understanding. It contends that the evolutionary background of moral intuitions does not necessarily render them inadequate, and that both deontological and consequentialist judgments likely depend on evolved intuitions to a significant degree. Furthermore, the tendency to dismiss certain influences on moral judgment as irrelevant can itself be explained psychologically. Considering the psychological account presented, mind-independent accounts of morality become less plausible. The dissertation concludes that while empirical moral psychology reveals important constraints on normative theorizing, it does not decisively favor consequentialism over deontology. To assess the significance of empirical-scientific findings for ethics, a nuanced understanding of the origins of moral judgments is nevertheless indispensable. (shrink)

People can be uncertain in their moral judgments. Philosophers have argued that such uncertainty can either refer to the underlying empirical facts (empirical uncertainty) or to the normative evaluation of these facts itself (normative uncertainty). Psychological investigations of this distinction, however, are rare. In this paper, we combined factor-analytical and experimental approaches to show that empirical and normative uncertainty describe two related but different psychological states. In Study 1, we asked N = 265 participants to describe a (...) case of moral uncertainty and to rate different aspects of their uncertainty about this case. Across this wide range of moral scenarios, our items loaded onto three reliable factors: lack of information, unclear consequences, and normative uncertainty. In Study 2, we confirmed this factor structure using predefined stimulus material. N = 402 participants each rated eight scenarios that systematically varied in their degree of uncertainty regarding the consequences of the described actions and in the value conflict that was inherent to them. The empirical uncertainty factors were mainly affected by the introduction of uncertainty regarding consequences, and the normative uncertainty factor was mainly affected by the introduction of value conflict. Our studies provide evidence that the distinction between empirical and normative uncertainty accurately describes a psychological reality. We discuss the relevance of our findings for research on moral judgments and decision-making, and folk metaethics. (shrink)

Empirical evidence indicates that much of human behavior is unconscious and automatic. This has led some philosophers to be skeptical of responsible agency or personhood in the moral sense. I present two arguments defending agency from these skeptical concerns. My first argument, the “margin of error” argument, is that the empirical evidence is consistent with the possibility that our automatic behavior deviates only slightly from what we would do if we were in full conscious control. Responsible agency requires (...) only that our actions more or less express our conscious goals and values. My second argument is a non-realist defense of moral agency. If we are willing to reject metaethical realism about agents, then there may be good reasons why we should retain the concept of agency in our moralizing, even if automaticity undermines the belief that we are really in conscious control of our behavior. We can do this by adopting a “reactive attitudes” approach to moral responsibility. On this view, agency is determined not by actual features of human psychology but by the attitudes and practices that we ought to adopt in response to the actions and motivations of individuals.

With the rapid recent growth of naturalized metaethics, Richard Joyce’s paper sounds an appropriate cautionary note. It’s easy to be overwhelmed by sexy new data and to neglect the difficulties in using the data to draw major philosophical conclusions. One of the central views in the sights of naturalists has been moral rationalism. Jonathan Haidt (2001), Joshua Greene (this volume), Jesse Prinz (forthcoming), and I (2002, 2004b) have all used recent empirical findings to challenge moral rationalist views. Although (...) Joyce is not himself a moral rationalist (see Joyce 2002), he deftly works to beat back our attacks on moral rationalism. Here my goal is to uphold the view that empirical work can challenge moral rationalism in the aftermath of Joyce’s insightful discussion. (shrink)

One way to interpret the work of Joshua Greene (2001; 2008; 2014) is that the wave of empirical research into moral decision-making is a way for us to become more confident in our ability to gain moral knowledge. We argue that empirical research into moral judgment has shown (both survey-based and brain-based) that the grounds of moral judgment are opaque on several dimensions. We argue that we cannot firmly grasp what the morally relevant/irrelevant features of a decision context (...) are, understand which cognitive system responds to said features, and further know that we are actually basing our judgment upon what we take to be the morally relevant features. That is, we argue that moral judgment is very much like other kinds of judgment: Deeply influenced by facts about the decision-context and the decision-maker. However, if moral judgment is merely the exercise of our general judgment making faculty, we shouldn’t be surprised by this result. We conclude by considering what this means for our practice of making moral judgments. (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.

Thomas Pölzler’s book offers the first detailed study that focuses explicitly on the promise of science-based arguments for and against moral realism (of both the natural and non-natural kind). His two central claims are that sound arguments bearing on the realism/anti-realism debate are possible, and, yet, that four central attempts to derive metaethical conclusions from science-based arguments uniformly fail. The book then provides several recommendations for future science-based contributions to the realism/anti-realism debate to do better. The book is a valuable (...) and thought-provoking contribution to experimental metaethics and, in particular, to debates surrounding experimental studies of folk-moral realism, where it provides an insightful and handy guide to the field. In what follows, I briefly lay out the book’s main arguments, focusing on Pölzler’s assessment of existing science-based arguments, along with some critical remarks, before providing a broader evaluation.
