Segundo David Copp, o cenário moral requer a compreensão de três aspectos inter-relacionados básicos: identificar a natureza dos juízos morais, especificar a justificação dessas decisões e determinar o papel da sociedade moral neste esquema. Para isso, o autor discute a necessidade de uma teoria cognitivista da linguagem normativa, assim como uma teoria da justificação dos códigos morais. O propósito deste artigo é analisar em que medida a teoria moral de Copp consegue acomodar a metodologia construtivista sobre as bases realistas de (...) seu naturalismo moral sem desmantelar seu propósito naturalista de relacionar propriedades morais à propriedades naturais.

Non-skeptical robust realists about normativity, mathematics, or any other domain of non- causal truths are committed to a correlation between their beliefs and non- causal, mind-independent facts. Hartry Field and others have argued that if realists cannot explain this striking correlation, that is a strong reason to reject their theory. Some consider this argument, known as the Benacerraf–Field argument, as the strongest challenge to robust realism about mathematics, normativity, and even logic. In this article I offer two closely related accounts (...) for the type of explanation needed in order to address Field's challenge. I then argue that both accounts imply that the striking correlation to which robust realists are committed is explainable, thereby discharging Field's challenge. Finally, I respond to some objections and end with a few unresolved worries. (shrink)

Several authors believe that metaethicists ought to leave their comfortable armchairs and engage with serious empirical research. This paper provides partial support for the opposing view, that metaethics is rightly conducted from the armchair. It does so by focusing on debunking arguments against robust moral realism. Specifically, the article discusses arguments based on the possibility that if robust realism is correct, then our beliefs are most likely insensitive to the relevant truths. These arguments seem at first glance to be dependent (...) on empirical research to learn what our moral beliefs are sensitive to. It is argued, however, that this is not so. The paper then examines two thought experiments that have been thought to demonstrate that debunking arguments might depend on empirical details and argues that the conclusion is not supported. (shrink)

I argue that one’s views about which “metaphysical laws” obtain—including laws about what is identical with what, about what is reducible to what, and about what grounds what—can be used to deflect or neutralize the threat posed by a debunking explanation. I use a well-known debunking argument in the metaphysics of material objects as a case study. Then, after defending the proposed strategy from the charge of question-begging, I close by showing how the proposed strategy can be used by certain (...) moral realists to resist the evolutionary debunking arguments.

Epistemic trespassers judge matters outside their field of expertise. Trespassing is ubiquitous in this age of interdisciplinary research and recognizing this will require us to be more intellectually modest.

A constructivist defense of ethical objectivity in contrast to debunking arguments.

Félix Aubé Beaudoin | : Le dilemme darwinien, formulé par Sharon Street, somme les réalistes moraux d’expliquer pourquoi de nombreux jugements qui sont des candidats au statut de vérités morales indépendantes sont aussi ceux qui ont une grande valeur sélective. Les réalistes peuvent soit nier, soit affirmer l’existence d’un lien entre pressions évolutionnistes et vérités morales. Selon Street, la première option mène au scepticisme tandis que la seconde est indéfendable sur le plan scientifique. Peter Singer et Katarzyna de Lazari-Radek optent (...) pour la première branche de ce dilemme. Dans cet article, la stratégie argumentative qu’ils adoptent — la réponse naturelle — sera soumise à un examen critique. Deux objections seront formulées. La première est d’ordre épistémologique : l’intuitionnisme philosophique défendu par les auteurs fait face à des difficultés majeures. La seconde, plus fondamentale, est que leur solution ne permet pas d’expliquer autrement que par un heureux hasard l’alignement entre les vérités morales et les jugements ayant une valeur sélective. | : According to Sharon Street’s Darwinian Dilemma, moral realists must explain why many judgments that are likely to be independent moral truths are those it would be evolutionarily adaptive to hold. Realists can either deny or assert the existence of a relation between evolutionary influences and moral truths. The first option leads to skepticism, while the second is unacceptable on scientific grounds, says Street. Peter Singer and Katarzyna de Lazari-Radek take the first horn of this dilemma. In this article, the argumentative strategy they adopt — the Natural Reply - is submitted to critical scrutiny. Two objections are raised. The first objection is epistemological : philosophical intuitionism, as defended by the authors, is an untenable position. The second objection is that their solution must appeal to unlikely coincidences to account for the overlap between independent moral truths and evolutionarily adaptive attitudes. (shrink)

Moral realists face an epistemological challenge: they must explain why many judgments that are likely to be moral truths are those it would be evolutionarily adaptive to hold. Is it a coincidence? Do evolutionary forces track these truths?Third-factor explanationis the strategy most commonly adopted by moral realists to explain this striking correlation. In this article, I argue that it does not allow them to meet the challenge.

We argue that Reasons Fundamentalism, as defended by T.M. Scanlon, faces two important difficulties—one ontological, the other epistemological—namely the ontological proliferation problem and the reliability challenge. We suggest that formal constructivism can avoid these difficulties, and that Scanlon would do well to adopt it. We also show that Scanlon’s three main objections to this view depend either on a misunderstanding of what formal constructivism is or on a question-begging argument in favour of realism.

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

Street’s (Philos Stud 127(1):109–166, 2006) Darwinian Dilemma purports to show that evolutionary considerations are in tension with realist theories of value, which include moral realism. According to this argument, moral realism can only be defended by assuming an implausible tracking relation between moral attitudes and moral facts. In this essay, I argue that this tracking relation is not as implausible as most people have assumed by showing that the three main objections against it are flawed. Since this is a key (...) premise in the reasoning, I conclude that the Darwinian Dilemma against moral realism can be resisted. (shrink)

I show that an overlooked feature of our moral life—moral status—provides a route to vindicating naturalist moral realism in much the same way that the Humean theory of motivation and judgment internalism are used to undermine it. Moral status presents two explanatory burdens for metaethical views. First, a given view must provide an ecumenical explanation of moral status, which does not depend on the truth of its metaethical claims (say, that there are mind-independent facts about moral status). Second, its explanation (...) must be consistent with persistent normative ethical disagreement about what constitutes moral status. I conclude that naturalist moral realism succeeds, while quasi-realism fails because it cannot meet the latter requirement. This argument has three results: we have a new route for metaethical vindication more generally and for naturalist moral realism in particular; quasi-realism's plausibility is undermined by an inability to explain disagreement, but not for the familiar reasons. (shrink)

Among the available metaethical views, it would seem that moral realism—in particular moral naturalism—must explain the possibility of moral progress. We see this in the oft-used argument from disagreement against various moral realist views. My suggestion in this paper is that, surprisingly, metaethical constructivism has at least as pressing a need to explain moral progress. I take moral progress to be, minimally, the opportunity to access and to act in light of moral facts of the matter, whether they are mind-independent (...) or -dependent. For the metaethical constructivist, however, I add that moral progress ought also mean that agents come to be or could come to be motivated to act in light of the right kind of moral judgments. Together I take this to mean that, for all forms of constructivism, moral progress must be explained as a form of moral improvement, or agents aspiring to be better sorts of moral agents. In what moral improvement consists differs for various forms of constructivism. Here I distinguish between three different versions of metaethical constructivism: Humean constructivists as represented by Street, Kantian constitutivist constructivists as represented by Korsgaard, and constructivists about practical reason as represented by Carla Bagnoli. I conclude by showing that only constructivism as a view about practical reason can fully account for moral progress qua the opportunity for moral improvement. (shrink)

Evolutionary debunking arguments (EDAs) have attracted extensive attention in meta-ethics, as they pose an important challenge to moral realism. Mogensen (2015) suggests that EDAs contain a fallacy, by confusing two distinct forms of biological explanation – ultimate and proximate. If correct, the point is of considerable importance: evolutionary genealogies of human morality are simply irrelevant for debunking. But we argue that the actual situation is subtler: while ultimate claims do not strictly entail proximate ones, there are important evidential connections between (...) the two. Attending to these connections clears ground for a new and improved EDA. However, it also brings into view some possible problems with EDAs that have been largely neglected so far. (shrink)

Sidgwick's seminal textThe Methods of Ethicsleft off with an unresolved problem that Sidgwick referred to as the dualism of practical reason. The problem is that employing Sidgwick's methodology of rational intuitionism appears to show that there are reasons to favour both egoism and utilitarianism. Katarzyna de Lazari-Radek and Peter Singer offer a solution in the form of an evolutionary debunking argument: the appeal of egoism is explainable in terms of evolutionary theory. I argue that like rational prudence, rational benevolence is (...) subject to debunking arguments and so problematic, but also – and more importantly – that debunking arguments are irrelevant in the debate over the dualism of practical reason on the view of reason and rational intuitionism that Lazari-Radek and Singer embrace. Either both egoism and utilitarianism are debunked, or neither are. If I am right, Sidgwick's dualism is left standing. (shrink)

We argue that there is a large class of questions—specifically questions about how to epistemically evaluate environments that currently available epistemic theories are not well-suited for answering, precisely because these questions are not about the epistemic state of particular agents or groups. For example, if we critique Facebook for being conducive to the spread of misinformation, then we are not thereby critiquing Facebook for being irrational, or lacking knowledge, or failing to testify truthfully. Instead, we are saying something about the (...) social media environment. In this paper, we first propose that a new branch of epistemology–Environmental Epistemology–is needed to address these questions. We argue that environments can be proper objects of epistemic evaluation, and that there are genuine epistemic norms that govern environments. We then provide a positive account of these norms and conclude by considering how recognition of these norms may require us to rethink longstanding epistemic debates. (shrink)

I develop and defend "metaethical experientialism," the thesis that phenomenal facts explain certain kinds of value facts. I argue, for example, that anyone who knows what it’s like to feel extreme pain is in a position to know that that kind of experience is bad. I argue that metaethical experientialism yields genuine counterexamples to the principle that no ethical conclusion can be derived from purely descriptive premises. I also discuss the prospects for a pluralistic metaethics, whereby different metaethical theories hold (...) for different classes of ethical facts. (shrink)

In recent years there has been a growing interest among mainstream Anglophone moral philosophers in the empirical study of human morality, including its evolution and historical development. This chapter compares these developments with an earlier point of contact between moral philosophy and the moral sciences in the early decades of the Twentieth century, as manifested in some of the less frequently discussed arguments of G. E. Moore and W. D. Ross. It is argued that a critical appreciation of Moore and (...) Ross’s response to the emerging moral sciences of their day has significant implications for contemporary moral epistemology. The chapter also offers a novel interpretation of G. E. Moore’s ‘open question argument’. (shrink)

In this paper I develop a genealogical approach for investigating and evaluating conspiracy theories. I argue that conspiracy theories with an epistemically problematic genealogy are (in virtue of that fact) epistemically undermined. I propose that a plausible type of candidate for such conspiracy theories involves what I call ‘second-order conspiracies’ (i.e. conspiracies that aim to create conspiracy theories). Then, I identify two examples involving such conspiracies: the antivaccination industry and the industry behind climate change denialism. After fleshing out the mechanisms (...) by which these industries systematically create and disseminate specific types of conspiracy theories, I examine the implications of my proposal concerning the particularism/generalism debate and I consider the possibility of what I call local generalism. Finally, I tackle three objections. It could be objected that a problematic genealogy for T merely creates what Dentith (2022) calls ‘type-1’ (or ‘weak’) suspicion for T. I also consider a challenge according to which the genealogical method is meta-undermined, as well as an objection from epistemic laundering. (shrink)

The blossoming literature on genealogy in recent years has come as somewhat of a pleasant surprise to the historically inclined among us. It has not, however, come without its difficulties. As I see it, the literature on genealogy is guilty of two conflations, what I call the “debunking/problematizing conflation” and the “problematizing/rationalizing conflation.” Both are the result of the inadequate typological maps currently used to organize the literature. As a result, what makes many genealogies philosophically interesting often remains obscure. In (...) response, I propose a new two-dimensional typology that avoids these conflations and outfits us with a richer conceptual vocabulary with which to understand and organize the genealogies which populate the literature. By identifying a second dimension of analysis which has thus far gone untheorized, my typology enables us to elucidate the various normative objectives and objects of investigation structuring a literature which is more diverse than previously acknowledged. We can thus get a clearer understanding of the problems those genealogies face, of their critical potential, and of their implications for our conception of critique. (shrink)

It can easily look like evolution is in a better position to explain the reliability of our perceptual beliefs than the reliability of our moral beliefs. This paper takes a closer look at the issue and argues that there’s no reason—no reason which armchair philosophers could uncover—to think evolution can better explain perceptual reliability than moral reliability. It also offers a diagnosis of why it seemed otherwise. The diagnosis concerns our need to use the truth predicate as a generalizing logical (...) device in the perceptual case but not in the moral case. (shrink)

The article discusses retributive justice and punitive restraint in response to the worst types of crime. I take the Breivik Case as a starting point. Anders Behring Breivik was sentenced to 21 years of preventive detention for killing 69 people, mainly youths, at Utøya and 8 people in Oslo on July 22nd, 2011. Retributivist theories as well as commonly held retributive intuitions suggest that much harsher punishment is required for such crimes. According to some retributivist theories, most notably on the (...) influential theories of Kant and Hegel, the death penalty is warranted for murderers like Breivik. This suggests that the rationale for punitive restraint in a case like the Breivik Case can only be found in forward- looking, consequentialist theories of punishment, or by adding to retributivist theories a side-constraint in the form of a principle of parsimony. However, I argue that if we look closer at the function of punishment in the retributivist theories of Kant and Hegel, they too imply a rationale for punitive restraint, even for such horrific crimes as here discussed. Against Kant and Hegel’s own views on the death penalty, I argue that their broader “freedom theories” of retributive justice do not imply the justice of the death penalty or life imprisonment. In the last part of the article, I explore differences in the concepts of freedom entailed by Kant and Hegel’s theories, and I relate these to some of the background factors relevant to the Breivik Case.

In this paper, we propose a defence of Value Realism that relies on the unusual combination of Values Realism with Sentimentalism. What this account, which we call “Sentimental Realism”, holds, in a nutshell, is that what makes evaluative facts special is their relationship to emotions. More precisely, Sentimental Realism claims that evaluative facts are fully objective facts, but that such facts are picked out by concepts that are response-dependent, in the sense that they are essentially tied to emotions. Our plan (...) is as follows. We shall start with a presentation of Sentimental Realism and a discussion of its main virtues. On the basis of this, we shall discuss an objection to Value Realism that draws on evolutionary considerations, the Evolutionary Debunking Argument. We shall argue that Sentimental Realism safely escapes from this dilemma. (shrink)

Many hope that our values, purged of messy human contingency, could aspire to correspond with mind-independent, rationally obligatory, and eternal ethical facts. But if the arguments of this thesis are on the right track, we should reject the search for non-natural and mind-independent moral truths.

Upon introspection, we judge that suffering feels bad. I argue there is no appearance-reality gap when it comes to introspective judgments about simple, intrinsic, nonrepresentational phenomenal states like itches, tingling, and suffering's feeling bad. On constitutivism about phenomenal introspection, there is no appearance-reality gap here because these judgments are literally constituted by the phenomenal states they are about. As a result, we are directly acquainted with the intrinsic properties of experience in having these judgments. Reflecting on our direct acquaintance with (...) intrinsic badness, we can know that our suffering instantiates this judgment-independent evaluative property. (shrink)

The fact that debunkers can turn to the argument from disagreement for help is ofcourse not a surprise. After all, both types of challenge basically pursue the same,skeptical conclusion. What I have tried to show, however, is that they are related in amore intimate way.

Proponents of impure moral perception claim that, while there are perceptual moral experiences, these experiences epistemically depend on a priori moral knowledge. Proponents of pure moral perception claim that moral experiences can justify independently of substantive a priori moral knowledge. Some philosophers, most notably David Faraci, have argued that the pure view is mistaken, since moral perception requires previous moral background knowledge, and such knowledge could not itself be perceptual. I defend pure moral perception against this objection. I consider two (...) ways to understand the notion of “background knowledge” that is crucial to the objection. On a reading, the claim that background knowledge is necessary for moral perception is likely false. On a second and weaker reading, the claim is true, but the background knowledge in question could be perceptual, and thus compatible with pure moral perception. Thus, the objection fails. (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.

There are several important arguments in metaethics that rely on explanatory considerations. Gilbert Harman has presented a challenge to the existence of moral facts that depends on the claim that the best explanation of our moral beliefs does not involve moral facts. The Reliability Challenge against moral realism depends on the claim that moral realism is incompatible with there being a satisfying explanation of our reliability about moral truths. The purpose of this chapter is to examine these and related arguments. (...) In particular, this chapter will discuss four kinds of arguments – Harman’s Challenge, evolutionary debunking arguments, irrelevant influence arguments, and the Reliability Challenge – understood as arguments against moral realism. The main goals of this chapter are (i) to articulate the strongest version of these arguments; (ii) to present and assess the central epistemological principles underlying these arguments; and (iii) to determine what a realist would have to do to adequately respond to these arguments.

I believe that Tom is the proud father of a baby boy. Why do I think his child is a boy? A natural answer might be that I remember that his name is ‘Owen’ which is usually a boy’s name. Here I’ve given information that might be part of a causal explanation of my believing that Tom’s baby is a boy. I do have such a memory and it is largely what sustains my conviction. But I haven’t given you just (...) any causally relevant information, I’ve given my grounds for my belief. I’ve given reasons that might justify me in supposing that Tom’s baby is a boy. Less naturally, the question might be taken as a request for a broader causal explanation of my holding this belief. Appropriate answers might cite all manner of facts concerning the evolution of the human race, why I chose to pursue philosophy and hence came to know Tom, the mechanisms of email transmission, the firing of various neurons, the circumstances of concept formation as a result of which I’m able to grasp the thought that Tom’s baby is a boy, and so on. It is an interesting question what distinguishes the narrower set of answers that I first suggested. I won’t pursue that here. I assume you have a good enough sense of the distinction I’m drawing. We might call the narrower set of answers justifying reasons, the kind of reasons I might cite in justifying my belief. Answers of the first sort are clearly relevant to epistemological evaluation. In assessing whether you know p or are rational in believing it to the degree you do, I will naturally want to consider what reasons you have for your belief. In deliberating myself about whether to believe p, in seeking an answer to the question of whether p, I will naturally consider what reasons or grounds I have to suppose that p. But what I want to focus on here is how explanations of the broader sort bear on such questions as whether to believe p. From a third-person perspective we can ask, ‘In assessing the epistemic status of S’s belief that p, what is the relevance of causal information that lies outside of the realm of justifying reasons?’ From the first-person standpoint we can ask ‘In seeking to answer whether p, how should such causal information affect my deliberations?’ At first it might seem that such broader causal information could have little relevance if any. Like any belief my belief that p can be traced back to innumerable causes from far and wide.. (shrink)

We think of logic as objective. We also think that we are reliable about logic. These views jointly generate a puzzle: How is it that we are reliable about logic? How is it that our logical beliefs match an objective domain of logical fact? This is an instance of a more general challenge to explain our reliability about a priori domains. In this paper, I argue that the nature of this challenge has not been properly understood. I explicate the challenge (...) both in general and for the particular case of logic. I also argue that two seemingly attractive responses – appealing to a faculty of rational insight or to the nature of concept possession – are incapable of answering the challenge. (shrink)

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

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)

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)

Suppose we grant that evolutionary forces have had a profound effect on the contours of our normative judgments and intuitions. Can we conclude anything from this about the correct metaethical theory? I argue that, for the most part, we cannot. Focusing my attention on Sharon Street’s justly famous argument that the evolutionary origins of our normative judgments and intuitions cause insuperable epistemological difficulties for a metaethical view she calls "normative realism," I argue that there are two largely independent lines of (...) argument in Street’s work which need to be teased apart. The first of these involves a genuine appeal to evolutionary considerations, but it can fairly easily be met by her opponents. The second line of argument is more troubling; it raises a significant problem, one of the most difficult in all of philosophy, namely how to justify our reliance on our most basic cognitive faculties without relying on those same faculties in a question-begging manner. However, evolutionary considerations add little to this old problem, and rejecting normative realism is not a way to solve it. (shrink)

Debunking arguments against both moral and mathematical realism have been pressed, based on the claim that our moral and mathematical beliefs are insensitive to the moral/mathematical facts. In the mathematical case, I argue that the role of Hume’s Principle as a conceptual truth speaks against the debunkers’ claim that it is intelligible to imagine the facts about numbers being otherwise while our evolved responses remain the same. Analogously, I argue, the conceptual supervenience of the moral on the natural speaks presents (...) a difficulty for the debunker’s claim that, had the moral facts been otherwise, our evolved moral beliefs would have remained the same.

This chapter offers an overview of four key debates about the roles of emotion in morality. First, many believe that emotions are an important psychological mechanism for explaining altruistic behavior and moral conscience in humans. Second, there is considerable debate about the causal role of affective reactions in moral judgment. Third, some philosophers have argued that emotions have a constitutive role in moral thought and even moral facts. Finally, philosophers disagree about whether affective influence undermines the justification of moral beliefs (...) or, in suitable circumstances, guides us toward moral truth. (shrink)

This chapter examines the influence of the empirical sciences (e.g., physics, biology, psychology) in contemporary analytic philosophy, with focus on philosophical theories that are guided by findings from the empirical sciences. Scientific approaches to philosophy follow a tradition of philosophical naturalism associated with Quine, which strives to ally philosophical methods and theories more closely with the empirical sciences and away from a priori theorizing and conceptual analysis.

I discuss Benacerraf's epistemological challenge for realism about areas like mathematics, metalogic, and modality, and describe the pluralist response to it. I explain why normative pluralism is peculiarly unsatisfactory, and use this explanation to formulate a radicalization of Moore's Open Question Argument. According to the argument, the facts -- even the normative facts -- fail to settle the practical questions at the center of our normative lives. One lesson is that the concepts of realism and objectivity, which are widely identified, (...) are actually in tension. (shrink)

Arguments attempting to debunk moral beliefs, by showing they are unjustified, have tended to be global, targeting all moral beliefs or a large set of them. Popular debunking arguments point to various factors purportedly influencing moral beliefs, from evolutionary pressures, to automatic and emotionally-driven processes, to framing effects. We show that these sweeping arguments face a debunker’s dilemma: either the relevant factor is not a main basis for belief or it does not render the relevant beliefs unjustified. Empirical debunking arguments (...) in ethics can avoid this predicament, but only if they are refocused on highly selective classes of moral belief. Experimental data can combine with familiar consistency reasoning to reveal that like cases are not being treated alike. Selective debunking arguments are unlikely to yield sweeping sceptical conclusions, but they can lead to rational moral change. (shrink)
