Experimental moral philosophy began to emerge as a methodology inthe last decade of the twentieth century, a branch of the largerexperimental philosophy approach. From the beginning,it has been embroiled in controversy on a number of fronts. Somedoubt that it is philosophy at all. Others acknowledge that it isphilosophy but think that it has produced modest results at best andconfusion at worst. Still others think it represents an important advance., Before the research program can be evaluated, we should have someconception of (...) its scope. But controversy surrounds questionsabout its boundaries as well. Uncontroversially, the distinctionbetween experimental and non-experimental philosophy is not identicalto the distinction between a posteriori and a prioriphilosophy. Experimental evidence is a proper subset of empiricalevidence, which is itself a subset of a posteriorievidence.

I argue that our best science supports the rationalist idea that, independent of reasoning, emotions aren’t integral to moral judgment. There’s ample evidence that ordinary moral cognition often involves conscious and unconscious reasoning about an action’s outcomes and the agent’s role in bringing them about. Emotions can aid in moral reasoning by, for example, drawing one’s attention to such information. However, there is no compelling evidence for the decidedly sentimentalist claim that mere feelings are causally necessary or sufficient for making (...) a moral judgment or for treating norms as distinctively moral. I conclude that, even if moral cognition is largely driven by automatic intuitions, these shouldn’t be mistaken for emotions or their non-cognitive components. Non-cognitive elements in our psychology may be required for normal moral development and motivation but not necessarily for mature moral judgment. (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)

This chapter discusses contemporary scientific research on the role of reason and emotion in moral judgment. The literature suggests that moral judgment is influenced by both reasoning and emotion separately, but there is also emerging evidence of the interaction between the two. While there are clear implications for the rationalism-sentimentalism debate, we conclude that important questions remain open about how central emotion is to moral judgment. We also suggest ways in which moral philosophy is not only guided by empirical research (...) but continues to guide it. (shrink)

Implicit cognition is cognition that happens automatically and (typically) non-consciously. In moral psychology, implicit cognition is almost always understood in terms of dual process models of moral judgment. In this chapter, we address the question whether implicit moral judgment is usefully cashed out in terms of automatic (“type 1”) processes, and what the limitations of this approach are. Our chapter has six sections. In (1), we provide a brief overview of dual process models of domain-general (moral and non-moral) cognition. (2) (...) reviews a recent debate regarding the soundness of dual process models to begin with. Section (3) is about dual process accounts of moral judgment specifically. The last three sections then survey attempts to go beyond a simplistic automatic/controlled (“type 2”) distinction in conceptualizing implicit moral cognition. Recently, three main theoretical approaches have emerged, which all revolve around the questions whether type 2 processing can successfully penetrate implicit moral cognition. First, rational learning approaches highlight how episodes of moral learning can feed back into and shape our moral intuitions (4). Second, so-called triple process models suggest that automatic cognitive outputs can under certain circumstances be reined in by reflective cognition (5). Finally, recent evidence shows that moral reasoning is not as impotent as earlier developments in empirical moral psychology claimed to demonstrate (6). (shrink)

How exactly do mental disorders affect one’s agency? How might therapeutic interventions help patients regain or improve their autonomy? Do only some disorders excuse morally inappropriate behavior, such as theft or child neglect? Or is there nothing about having a disorder, as such, that affects whether we ought to praise or blame someone for their moral success or failure? Our volume gathers together empirically-informed philosophers who are well equipped to tackle such questions. Contributors specialize in free will, agency, and responsibility, (...) but they are informed by current scientific and clinical approaches to a wide range of psychopathologies, including autism, addiction, Tourette syndrome, personality disorders, depression, dementia, phobias, schizophrenia, and obsessive-compulsive disorder. These conditions exhibit a diverse array of symptoms that can contribute quite differently to being blameworthy or praiseworthy. (shrink)

The burgeoning science of ethics has produced a trend toward pessimism. Ordinary moral thought and action, we’re told, are profoundly influenced by arbitrary factors and ultimately driven by unreasoned feelings. This book counters the current orthodoxy on its own terms by carefully engaging with the empirical literature. The resulting view, optimistic rationalism, shows the pervasive role played by reason, and ultimately defuses sweeping debunking arguments in ethics. The science does suggest that moral knowledge and virtue don’t come easily. However, despite (...) the heavy influence of automatic and unconscious processes that have been shaped by evolutionary pressures, we needn’t reject ordinary moral psychology as fundamentally flawed or in need of serious repair. Reason can be corrupted in ethics just as in other domains, but a special pessimism about morality in particular is unwarranted. Moral judgment and motivation are fundamentally rational enterprises not beholden to the passions. (shrink)

I offer and develop an original answer to the question of whether emotion plays an important role in the formation of moral thought. In a nutshell, my answer will be that if motivational internalism provides us with a correct description of the nature of moral thought, then emotion plays an important role because emotion is required to explain or ground the behavioral dispositions that are involved in moral thought.

ABSTRACTRecent discussions in the field of moral cognition suggest that the relationship between emotion and judgment-formation can be described in three separate ways: firstly, it narrows our atte...

In this paper, I argue that recent evidence regarding the psychological basis of moral cognition supports a form of (moderate) moral abolitionism. I identify three main problems undermining the epistemic quality of our moral judgments – contamination, reliability, and bad incentives – and reject three possible responses: neither moral expertise, nor moral learning, nor the possibility of moral progress succeed in solving the aforementioned epistemic problems. The result is a moderate form of moral abolitionism, according to which we should make (...) fewer moral judgments much more carefully. (shrink)

The issues of climate change and environmental degradation elicit diverse responses. This paper explores how an understanding of human moral psychology might be used to motivate conservation efforts. Moral concerns for the environment can relate to issues of harm or impurity . Aversions to harm are linked to concern for current or future generations, non-human animals, and anthropomorphized aspects of the environment. Concerns for purity are linked to viewing the environment as imbued with sacred value and therefore worthy of being (...) protected at all costs. While both harm-based and purity-based framings of environmental issues can sometimes backfire, we argue that making these moral concerns salient can nevertheless bring about moral responses to environmental issues. In sum, scientists' emerging knowledge about the moral mind can be used to facilitate the sustainable conservation of the planet. (shrink)

Naturalistic philosophers rely on literature search and review in a number of ways and for different purposes. Yet this article shows how processes of literature search and review are likely to be affected by widespread and systematic biases. A solution to this problem is offered here. Whilst the tradition of systematic reviews of literature from scientific disciplines has been neglected in philosophy, systematic reviews are important tools that minimize bias in literature search and review and allow for greater reproducibility and (...) transparency. If naturalistic philosophers wish to reduce bias in their research, they should then supplement their traditional tools for literature search and review by including systematic methodologies.

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)

From David Hume onwards, many philosophers have argued that moral thinking is characterized by a tendency to “project” our own mental states onto the world. This metaphor of projection may be understood as involving two empirical claims: the claim that humans experience morality as a realm of objective facts (the experiential hypothesis), and the claim that this moral experience is immediately caused by affective attitudes (the causal hypothesis). Elsewhere I argued in detail against one form of the experiential hypothesis. My (...) main aim in this paper is to show that, considering recent psychological studies about folk metaethics and the relation between moral judgements and emotions, the causal hypothesis must be considered problematic too. First, the most common argument in favor of the causal hypothesis is based on an implausible premise and a dubious assumption. Second, ordinary people’s moral experience is influenced by a non-affective factor, namely their openness to divergent moral views. And third, projectivism in general and its causal hypothesis in particular might not even hold true for affective moral judgements. This negative assessment of projectivism is significant both for our understanding of moral cognition as an empirical phenomenon and for metaethics. (shrink)

It has long been claimed that moral judgements are dominated by reason. In recent years, however, the tide has turned. Many psychologists and philosophers now hold the view that there is a close empirical association between moral judgements and emotions. In particular, they claim that emotions (1) co-occur with moral judgements, (2) causally influence moral judgements, (3) are causally sufficient for moral judgements, and (4) are causally necessary for moral judgements. At first sight these hypotheses seem well-supported. In this paper (...) I show, however, that appearances are deceiving. If one considers the relevant scientific studies in detail, one finds that in many interpretations the above hypotheses are either not supported or even contradicted by the available evidence. This conclusion is significant both for our understanding of moral judgements qua empirical phenomena and for normative ethics and metaethics. (shrink)

The philosophical debate over disgust and its role in moral discourse has focused on disgust’s epistemic status: can disgust justify judgments of moral wrongness? Or is it misplaced in the moral domain—irrelevant at best, positively distorting at worst? Correspondingly, empirical research into disgust has focused on its role as a cause or amplifier of moral judgment, seeking to establish how and when disgust either causes us to morally condemn actions, or strengthens our pre-existing tendencies to condemn certain actions. Both of (...) these approaches to disgust are based on a set of assumptions that I call, in what follows, the evidential model of disgust. This paper proposes an alternative model, which I call the response model. Instead of looking at disgust as a cause and justification of judgments of moral wrongness, I will argue that disgust is better understood as a response to wrongness. More precisely, I argue that disgust is a response to norm violations, and that it is a fitting response insofar as norm violations are potentially contagious and therefore pose a threat to the stability and maintenance of norms. (shrink)

I argue that information about the distal causes of moral beliefs, such as evolution, is only relevant for assessing the epistemic status of moral beliefs in cases where we cannot determine whether the proximal processes producing these beliefs are reliable just by examining the properties of these proximal processes. Any investigation into the epistemic status of moral beliefs given their causes should start with a look at proximal causes—not at evolution. I discuss two proximal psychological influences on moral beliefs—disgust and (...) sympathy—to demonstrate the feasibility of drawing epistemic conclusions from an examination of proximal causes alone. (shrink)

We can infer moral conclusions from nonmoral evidence using a three-step procedure. First, we distinguish the processes generating belief so that their reliability in generating true belief is statistically predictable. Second, we assess the processes’ reliability, perhaps by observing how frequently they generate true nonmoral belief or logically inconsistent beliefs. Third, we adjust our credence in moral propositions in light of the truth ratios of the processes generating beliefs in them. This inferential route involves empirically discovering truths of the form (...) “Process P, which generates belief in moral proposition M, has truth ratio T", and using them to discover probabilities for moral propositions. The inferential route is noncircular, and progress along it is driven fundamentally by induction. (shrink)

ABSTRACT Ethical and political attitudes are not randomly distributed in a population. Attitudes of family members, for example, tend to be more similar than those of a random sample of the same size. In the fields of social psychology and political science, the historically standard explanation for these attitude distribution patterns was that social and political attitudes are a function of environmental factors like parental socialization and prevailing social norms. This received view is, however, complicated by more recent work in (...) behavioral genetics, which consistently and repeatedly demonstrates that certain ethical and political attitudes dealing with issues like censorship, abortion, capital punishment, and immigration policy have a significant heritability coefficient, to wit, a substantial percentage of attitude variance in a population can be attributed to genetic variance, independent of environmental factors. In this paper, I argue that the genetic influence on our ethical and political attitudes is mediated by what we can agree to be irrelevant and distorting factors that can lead moral reasoning astray. Further, I argue that we should significantly lower our credences in ethical and political attitudes that fall within the domains of belief that involve significant genetic influence. (shrink)

The past few decades of moral psychology research have yielded empirical anomalies for rationalist theories of moral judgments. An increasing number of psychologists and philosophers argue that these anomalies are explained well by sentimentalism, the thesis that the presence of an emotion is necessary for the formation of a sincere moral judgment. The present review reveals that while emotions and moral judgments indeed often co-occur, there is scant evidence that emotions directly cause or constitute moral judgments. Research on disgust, anger, (...) sympathy, and guilt indicates that people only reliably experience emotions when judging conduct that is relevant to the welfare of the self and valued others. Moreover, many recent studies have either failed to replicate or exposed crucial confounds in the most cited evidence in support of sentimentalism. Moral psychologists should jettison sentimentalism, and focus instead on how considerations of harm and welfare—the core concepts of rationalist theories— interact with empirical beliefs to shape moral judgments.

Regard for Reason in the Moral Mind argues that a careful examination of the scientific literature reveals a foundational role for reasoning in moral thought and action. Grounding moral psychology in reason then paves the way for a defense of moral knowledge and virtue against a variety of empirical challenges, such as debunking arguments and situationist critiques. The book attempts to provide a corrective to current trends in moral psychology, which celebrate emotion over reason and generate pessimism about the psychological (...) mechanisms underlying commonsense morality. Ultimately, there is rationality in ethics not just despite but in virtue of the neurobiological and evolutionary materials that shape moral cognition and motivation. (shrink)

A traditional idea is that moral judgment involves more than calculating the consequences of actions; it also requires an assessment of the agent's intentions, the act's nature, and whether the agent uses another person as a means to her ends. I survey experimental developments suggesting that ordinary people often tacitly reason in terms of such deontological rules. It's now unclear whether we should posit a traditional form of the doctrine of double effect. However, further research suggests that a range of (...) non-consequentialist factors influence moral judgment, including intentions, commissions, personal harm, and agent-centered commitments. Many, if not all, such factors appear to affect how involved the agent is in bringing about an outcome. (shrink)

[Selected as EDITOR'S CHOICE] Background: Extant surveys of people’s attitudes toward human reproductive cloning focus on moral judgments alone, not emotional reactions or sentiments. This is especially important given that some (esp. Leon Kass) have argued against such cloning on the grounds that it engenders widespread negative emotions, like disgust, that provide a moral guide. Objective: To provide some data on emotional reactions to human cloning, with a focus on repugnance, given its prominence in the literature. Methods: This brief mixed-method (...) study measures the self-reported attitudes and emotions (positive or negative) toward cloning from a sample of participants in the United States. Results: Most participants condemned cloning as immoral and said it should be illegal. The most commonly reported positive sentiment was by far interest/curiosity. Negative emotions were much more varied, but anxiety was the most common. Only about a third of participants selected disgust or repugnance as something they felt and an even smaller portion had this emotion come to mind prior to seeing a list of options. Conclusions: Participants felt primarily interested and anxious about human reproductive cloning. They did not primarily feel disgust or repugnance. This provides initial empirical evidence that such a reaction is not appropriately widespread. (shrink)

Doris argues that our choices are heavily influenced by forces that we wouldn’t count as genuine reasons. This unsettling conclusion is motivated by a debunking argument so wide-ranging that it isn’t foisted upon us by the sciences. Doris sometimes seems to lower his ambitions when offering instead a skeptical hypothesis argument, but that conflicts with his aims in the book.

Moralization is a social-psychological process through which morally neutral issues take on moral significance. Often linked to health and disease, moralization may sometimes lead to good outcomes; yet moralization is often detrimental to individuals and to society as a whole. It is therefore important to be able to identify when moralization is inappropriate. In this paper, we offer a systematic normative approach to the evaluation of moralization. We introduce and develop the concept of ‘mismoralization’, which is when moralization is metaethically (...) unjustified. In order to identify mismoralization, we argue that one must engage in metaethical analysis of moralization processes while paying close attention to the relevant facts. We briefly discuss one historical example and two contemporary cases related to COVID-19 that we contend to have been mismoralized in public health. We propose a remedy of de-moralization that begins by identifying mismoralization and that proceeds by neutralizing inapt moral content. De-moralization calls for epistemic and moral humility. It should lead us to pull away from our tendency to moralize—as individuals and as social groups—whenever and wherever moralization is unjustified. (shrink)

Recent behavioral experiments, along with imaging experiments and neuropsychological studies appear to support the hypothesis that emotions play a causal or constitutive role in moral judgment. Those who resist this hypothesis tend to suggest that affective mechanisms are better suited to play a modulatory role in moral cognition. But I argue that claims about the role of emotion in moral cognition frame the debate in ways that divert attention away from other plausible hypotheses. I suggest that the available data may (...) be more plausibly explained by appeal to predictive and evaluative mechanisms, which are neither wholly affective nor straightforwardly cognitive. By recognizing this fact, we can begin to see why questions about the role of emotion in moral psychology are likely to be empirically misguided. (shrink)

In 1906, Henry Stephens Salt published a short collection of essays that presented several rhetorically powerful, if formally deficient arguments for the vegetarian position. By interpreting Salt as a moral sentimentalist with ties to Aristotelian virtue ethics, I propose that his aesthetic argument deserves contemporary consideration. First, I connect ethics and aesthetics with the Greek concepts of kalon and kalokagathia that depend equally on beauty and morality before presenting Salt’s assertion: slaughterhouses are disgusting, therefore they should not be promoted. I (...) suggest three areas of development since Salt’s death that could be fruitfully plumbed to rebuild this assertion into a contemporary argument: an updated analysis of factory farm conditions, insights from moral psychologists on the adaptive socio-biological benefits of disgust as a source of cognitive information, and hermeneutical considerations about the role of the audience that allow blameworthiness for slaughterhouse atrocities to be laid upon the meat-eater.

In light of recent empirical data, many psychologists and philosophers have turned away from rationalism about moral judgment and embraced sentimentalism. In the process, they have rejected the classical “moral signature” as a way of distinguishing moral from conventional norms in favor of a sentimentalist approach to carving out the moral domain. In this paper, we argue that this sentimentalist turn has been made prematurely. Although we agree that the experiments reveal that the classical approach is flawed, we propose to (...) replace it with an alternative, according to which a norm is moral precisely if it is justifiable to all. This does not hold for most norms based on disgust or loyalty to a particular community. We accommodate the fact that such norms are not merely conventional by introducing a third domain, the domain of ethics. Our proposal reveals that (psychological) rationalism is still a viable option, as a lot of the experimental evidence that features emotions concerns the domain of ethics rather than morality.

Alcohol intoxication is a major source of antisocial behavior in our society, strongly implicated in various forms of interpersonal aggression. Yet, moral philosophers have paid surprisingly little attention to the literature on alcohol and its effects. In part, this is because philosophers who have adopted a more empirically informed approach to moral psychology have gravitated toward moral sentimentalism, while the literature on alcohol intoxication fits very poorly with the sentimentalist account. Most contemporary research on the psychological effects of alcohol is (...) focused upon variants of the “disinhibition” theory, which suggests that alcohol does not provoke any specific affect, it merely weakens executive control. This research, we argue, lends support to a deontic moral psychology, which identifies our ability to suppress behavioral impulses as a central feature of moral agency. (shrink)

I argue that much philosophical discussion of moral disgust suffers from two ambiguities: first, it is not clear whether arguments for the moral authority of disgust apply to disgust as a consequence of moral evaluations or instead to disgust as a moralizing emotion; second, it is not clear whether the word ‘moral’ is used in a normative or in a descriptive sense. This lack of clarity generates confusion between ‘fittingness’ and ‘appropriateness’ of disgust. I formulate three conditions that arguments for (...) the moral authority of disgust need—but typically fail—to satisfy, in order to avoid (1) circularity, (2) the naturalistic fallacy, and (3) redundancy. These conditions are, respectively, (1) the identification of the direction of the causal relation between disgust and moral evaluation, (2) a demonstration that disgust is ‘fitting’ to morally relevant properties, and (3) a demonstration that disgust is ‘appropriate’ when elicited by these morally relevant properties. I will also suggest that, regardless of whether an argument for the moral authority of disgust can be made, it would be better to avoid the rather obscure term ‘moral disgust’. (shrink)

ABSTRACT It has been argued that so-called moral disgust is either not really moral or not really disgust. I maintain that sceptics are wrong: there is a distinct emotional response best described as ‘moral disgust’. I offer an account of its constitutive features.

According to Westermarck’s widely accepted explanation of the incest taboo, cultural prohibitions on sibling sex are rooted in an evolved biological disposition to feel sexual aversion toward our childhood coresidents. Bernard Williams posed the “representation problem” for Westermarck’s theory: the content of the hypothesized instinct is different from the content of the incest taboo —thus the former cannot be causally responsible for the latter. Arthur Wolf posed the related “moralization problem”: the instinct concerns personal behavior whereas the prohibition concerns everyone. (...) This paper reviews possible ways of defending Westermarck’s theory from the representation and moralization problems, and concludes that the theory is untenable. A recent study purports to support Westermarck’s account by showing that unrelated children raised in the same peer groups on kibbutzim feel sexual aversion toward each other and morally oppose third-party intra-peer-group sex, but this study has been misinterpreted. I argue that the representation and moralization problems are general problems that could potentially undermine many popular evolutionary explanations of social/moral norms. The cultural evolution of morality is not tightly constrained by our biological endowment in the way some philosophers and evolutionary psychologists believe. (shrink)

This paper examines the literature on meta-moral cognition and juxtaposes that with meta-cognition. At a basic level, the moral agent coordinates and assigns meaning to the various micro-concepts and moral concepts involved in a moral judgment. These concepts are combined to make moral assumptions. Meta-moral cognition is a higher level cognitive skill. The skill helps the moral agent to understand the cognitive process, control it, regulate the concepts and strategies used, and helps to reflect on the right and wrong of (...) the formulated moral judgment. To develop such moral taxonomy, the moral agent needs to understand the process of reasoning. (shrink)

How is ethical knowledge possible? One of the most promising answers is the moral sense view: we can acquire ethical knowledge through emotional experience. But this view faces a serious problem. Emotions are unreliable guides to ethical truth, frequently failing to fit the ethical status of their objects. This threatens to render the habit of basing ethical beliefs on emotions too unreliable to yield knowledge. I offer a new solution to this problem, with practical implications for how we approach ethical (...) decision-making. I argue that an agent can have a reliable belief-forming habit despite having unreliable emotions, so long as she is suitably attentive to defeaters. In moderately virtuous agents, unfitting ethical emotions are frequently accompanied by warning signs, such as negative metaemotions, epistemic feelings, moods, and social cues. An agent who cultivates the attentional skill of noticing these signs can prevent many of her unfitting emotions from translating into false beliefs. For a moderately virtuous agent with this skill, the habit of basing ethical beliefs on emotions will be reliable. The upshot is that emotion-based ethical knowledge is possible even for people whose emotions are unreliable, but only if we cultivate the skill of spotting defeaters. (shrink)

Experimental moral philosophy emerged as a methodology in the last decade of the twentieth century, as a branch of the larger experimental philosophy (X-Phi) approach. Experimental moral philosophy is the empirical study of moral intuitions, judgments, and behaviors. Like other forms of experimental philosophy, it involves gathering data using experimental methods and using these data to substantiate, undermine, or revise philosophical theories. In this case, the theories in question concern the nature of moral reasoning and judgment; the extent and sources (...) of moral obligations; the nature of a good person and a good life; even the scope and nature of moral theory itself. This entry begins with a brief look at the historical uses of empirical data in moral theory and goes on to ask what, if anything, is distinctive about experimental moral philosophy—how should we distinguish it from related work in empirical moral psychology? After discussing some strategies for answering this question, the entry examines two of the main projects within experimental moral philosophy, and then discusses some of the most prominent areas of research within the field. As we will see, in some cases experimental moral philosophy has opened up new avenues of investigation, while in other cases it has influenced longstanding debates within moral theory. (shrink)

An influential argument in bioethics involves appeal to disgust, calling on us to take it seriously as a moral guide (e.g. Kass, Miller, Kahan). Some argue, for example, that genetic enhancement, especially via human reproductive cloning, is repellant or grotesque. While objectors have argued that repugnance is morally irrelevant (e.g. Nussbaum, Kelly), I argue that the problem is more fundamental: it is psychologically irrelevant. Examining recent empirical data suggests that disgust’s influence on moral judgment may be like fatigue: an exogenous (...) influence, yielding a “performance error” that does not reflect our understanding of moral matters. This conclusion also challenges appeals to repugnance on other topics (such as homosexuality) and generally downplays the importance of disgust in moral discourse. (shrink)

Vaccine refusers often seem motivated by disgust, and they invoke ideas of purity, contamination and sanctity. Unfortunately, the emotion of disgust and its companion ideas are not directly responsive to the probabilistic and statistical evidence of research science. It follows that increased efforts to promulgate the results of vaccine science are not likely to contribute to increased rates of vaccination among persons who refuse vaccines because of the ‘ethics of sanctity’. Furthermore, the fact that disgust-based vaccine refusal is not monolithic (...) – vaccine refusers manifest disgust at different objects and invoke different ideas about purity and contamination – further complicates public health efforts to increase vaccination rates.

In this chapter we draw comparisons between Kass’ views on the normative authority of repugnance and social intuitionist accounts of moral judgement which are similarly sceptical about the role of reasoned reflection in moral judgement. We survey the empirical claims made in support of giving moral primacy to intuitions generated by emotions such as repugnance, as well as some common objections. We then examine accounts which integrate intuition and reflection, and argue that plausible accounts of wisdom are in tension with (...) Kass’ claim that our inarticulable emotional responses can be the expression of deep wisdom. We conclude that while repugnance and other emotions have a role to play in informing deliberation and judgement, we have reason to be cautious in giving them normative authority. Affective responses alone cannot discharge the burden of justification for moral judgement and are just one tool relied upon by those we consider wise. (shrink)
