For millennia, philosophers have speculated about the origins of ethics. Recent research in evolutionary psychology and the neurosciences has shed light on that question. But this research also has normative significance. A standard way of arguing against a normative ethical theory is to show that in some circumstances the theory leads to judgments that are contrary to our common moral intuitions. If, however, these moral intuitions are the biological residue of our evolutionary history, it is not clear why we should (...) regard them as having any normative force. Research in the neurosciences should therefore lead us to reconsider the role of intuitions in normative ethics. (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)

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)

Experimental research suggests that people draw a moral distinction between bad outcomes brought about as a means versus a side effect (or byproduct). Such findings have informed multiple psychological and philosophical debates about moral cognition, including its computational structure, its sensitivity to the famous Doctrine of Double Effect, its reliability, and its status as a universal and innate mental module akin to universal grammar. But some studies have failed to replicate the means/byproduct effect especially in the absence of other factors, (...) such as personal contact. So we aimed to determine how robust the means/byproduct effect is by conducting a meta-analysis of both published and unpublished studies (k = 101; 24,058 participants). We found that while there is an overall small difference between moral judgments of means and byproducts (standardized mean difference = 0.87, 95% CI 0.67 – 1.06; standardized mean change = 0.57, 95% CI 0.44 – 0.69; log odds ratio = 1.59, 95% CI 1.15 – 2.02), the mean effect size is primarily moderated by whether the outcome is brought about by personal contact, which typically involves the use of personal force.

The Emotional Construction of Morals is a book about moral judgements – the kinds of mental states we might express by sentences such as, ‘It's bad to flash your neighbors’, or ‘You ought not eat your pets’. There are three basic questions that get addressed: what are the psychological states that constitute such judgements? What kinds of properties do such judgements refer to? And, where do these judgements come from? The first question concerns moral psychology, the second metaethics and the (...) third is best construed as belonging to a domain that has been neglected in analytic value theory: the genealogy of morals. These are all separate branches of ethics, but they are interconnected. The thesis of the book is that moral judgements are emotional attitudes that refer to response-dependent properties, and that these responses have been shaped by cultural history. I call the view Constructive Sentimentalism. The first half of the book deals with sentiments, and the second half with construction. The second half also deals with relativism, because I argue that moral values are constructed differently across cultures and across individuals.Thus described, The Emotional Construction of Morals is a conventional contribution to analytic moral philosophy, taking on some of the core questions in that field and defending positions that have a long philosophical pedigree. Indeed, the theory I defend has roots in Hume and Nietzsche, though it departs from both in various ways. What makes the book somewhat unusual is that it seeks to defend traditional theories by appeal to recent work in psychology, neuroscience, anthropology and related fields. It is an exercise in methodological naturalism and committed to the view that we can answer traditional philosophical questions while treating ethics as a social science. Ethics and naturalism are hard to reconcile because ethics is a normative domain, …. (shrink)

Intent and mitigating circumstances play a central role in moral and legal assessments in large-scale industrialized societies. Al- though these features of moral assessment are widely assumed to be universal, to date, they have only been studied in a narrow range of societies. We show that there is substantial cross-cultural variation among eight traditional small-scale societies (ranging from hunter-gatherer to pastoralist to horticulturalist) and two Western societies (one urban, one rural) in the extent to which intent and mitigating circumstances influence (...) moral judgments. Although participants in all societies took such factors into account to some degree, they did so to very different extents, varying in both the types of considerations taken into account and the types of violations to which such considerations were applied. The particular patterns of assessment characteristic of large-scale industrialized societies may thus reflect relatively recently culturally evolved norms rather than inherent features of human moral judgment.

Johnston presents an argument for a form of immortality that divests the notion of any supernatural elements. The book is packed with illuminating philosophical reflection on the question of what we are, and what it is for us to persist over time.

Moral thinking pervades our practical lives, but where did this way of thinking come from, and what purpose does it serve? Is it to be explained by environmental pressures on our ancestors a million years ago, or is it a cultural invention of more recent origin? In The Evolution of Morality, Richard Joyce takes up these controversial questions, finding that the evidence supports an innate basis to human morality. As a moral philosopher, Joyce is interested in whether any implications follow (...) from this hypothesis. Might the fact that the human brain has been biologically prepared by natural selection to engage in moral judgment serve in some sense to vindicate this way of thinking--staving off the threat of moral skepticism, or even undergirding some version of moral realism? Or if morality has an adaptive explanation in genetic terms--if it is, as Joyce writes, "just something that helped our ancestors make more babies"--might such an explanation actually undermine morality's central role in our lives? He carefully examines both the evolutionary "vindication of morality" and the evolutionary "debunking of morality," considering the skeptical view more seriously than have others who have treated the subject.Interdisciplinary and combining the latest results from the empirical sciences with philosophical discussion, The Evolution of Morality is one of the few books in this area written from the perspective of moral philosophy. Concise and without technical jargon, the arguments are rigorous but accessible to readers from different academic backgrounds. Joyce discusses complex issues in plain language while advocating subtle and sometimes radical views. The Evolution of Morality lays the philosophical foundations for further research into the biological understanding of human morality. (shrink)

Everyone wants to be virtuous, but recent psychological investigations suggest that this may not be possible. Mark Alfano challenges this theory and asks, not whether character is empirically adequate, but what characters human beings could have and develop. Although psychology suggests that most people do not have robust character traits such as courage, honesty and open-mindedness, Alfano argues that we have reason to attribute these virtues to people because such attributions function as self-fulfilling prophecies - children become more studious if (...) they are told that they are hard-working and adults become more generous if they are told that they are generous. He argues that we should think of virtue and character as social constructs: there is no such thing as virtue without social reinforcement. His original and provocative book will interest a wide range of readers in contemporary ethics, epistemology, moral psychology and empirically informed philosophy. (shrink)

This is a commentary on a paper by the social psychologist C. Daniel Batson. I too think virtue is rare, but not so rare as Batson seems to think, despite his ingenious experiments on "moral hypocrisy.".

Do we know what we're doing, and why? Psychological research seems to suggest not: reflection and self-awareness are surprisingly uncommon and inaccurate. John M. Doris presents a new account of agency and responsibility, which reconciles our understanding of ourselves as moral agents with empirical work on the unconscious mind.

Does having a mental disorder, in general, affect whether someone is morally responsible for an action? Many people seem to think so, holding that mental disorders nearly always mitigate responsibility. Against this Naïve view, we argue for a Nuanced account. The problem is not just that different theories of responsibility yield different verdicts about particular cases. Even when all reasonable theories agree about what's relevant to responsibility, the ways mental illness can affect behavior are so varied that a more nuanced (...) approach is needed. (shrink)

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

Our brains were designed for tribal life, for getting along with a select group of others and for fighting off everyone else. But modern times have forced the world’s tribes into a shared space, resulting in epic clashes of values along with unprecedented opportunities. As the world shrinks, the moral lines that divide us become more salient and more puzzling. We fight over everything from tax codes to gay marriage to global warming, and we wonder where, if at all, we (...) can find our common ground. (shrink)

The fact of moral disagreement when conjoined with Conciliationism, an independently attractive view about the epistemic significance disagreement, seems to entail moral skepticism. This worries those who like Conciliationism, the independently attractive view, but dislike moral skepticism. Others, equally inclined against moral skepticism, think this is a reductio of Conciliationism. I argue that they are both wrong. There is no reductio and nothing to worry about.

I address Sinnott-Armstrong's argument that evidence of framing effects in moral psychology shows that moral intuitions are unreliable and therefore not noninferentially justified. I begin by discussing what it is to be epistemically unreliable and clarify how framing effects render moral intuitions unreliable. This analysis calls for a modification of Sinnott-Armstrong's argument if it is to remain valid. In particular, he must claim that framing is sufficiently likely to determine the content of moral intuitions. I then re-examine the evidence which (...) is supposed to support this claim. In doing so, I provide a novel suggestion for how to analyze the reliability of intuitions in empirical studies. Analysis of the evidence suggests that moral intuitions subject to framing effects are in fact much more reliable than perhaps was thought, and that Sinnott-Armstrong has not succeeded in showing that noninferential justification has been defeated.

In this article I explain why cognitive science (including some neuroscience) matters for normative ethics. First, I describe the dual-process theory of moral judgment and briefly summarize the evidence supporting it. Next I describe related experimental research examining influences on intuitive moral judgment. I then describe two ways in which research along these lines can have implications for ethics. I argue that a deeper understanding of moral psychology favors certain forms of consequentialism over other classes of normative moral theory. I (...) close with some brief remarks concerning the bright future of ethics as an interdisciplinary enterprise. (shrink)

In this essay, two different forms of debunking arguments are distinguished. On the type of debunking argument that I will promote, one attempts to undercut the justificatory status of a belief by showing that the belief was formed by an epistemically defective psychological process. I argue that there is a promising application of such a process debunking argument in metaethics. In normative ethics, however, process debunking arguments face greater obstacles.

We provide empirical evidence that people who believe in dualism are more likely to be uncomfortable with Deep Brain Stimulation (DBS) and to view it as threatening to their identity, humanity, or self. It is (neurocentric) materialists—who think the mind just is the brain—that are less inclined to fear DBS or to see it as threatening. We suggest various possible reasons for this connection. The inspiration for this brief report is a target article that addresses this issue from a theoretical (...) perspective. (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)

Should laws about sex and pornography be based on social conventions about what is disgusting? Should felons be required to display bumper stickers or wear T-shirts that announce their crimes? This powerful and elegantly written book, by one of America's most influential philosophers, presents a critique of the role that shame and disgust play in our individual and social lives and, in particular, in the law.Martha Nussbaum argues that we should be wary of these emotions because they are associated in (...) troubling ways with a desire to hide from our humanity, embodying an unrealistic and sometimes pathological wish to be invulnerable. Nussbaum argues that the thought-content of disgust embodies "magical ideas of contamination, and impossible aspirations to purity that are just not in line with human life as we know it." She argues that disgust should never be the basis for criminalizing an act, or play either the aggravating or the mitigating role in criminal law it currently does. She writes that we should be similarly suspicious of what she calls "primitive shame," a shame "at the very fact of human imperfection," and she is harshly critical of the role that such shame plays in certain punishments.Drawing on an extraordinarily rich variety of philosophical, psychological, and historical references--from Aristotle and Freud to Nazi ideas about purity--and on legal examples as diverse as the trials of Oscar Wilde and the Martha Stewart insider trading case, this is a major work of legal and moral philosophy.

Joining the debate over the roles of reason and appetite in the moral mind, In Praise of Desire takes the side of appetite. Acting for moral reasons, acting in a praiseworthy manner, and acting out of virtue are simply acting out of intrinsic desires for the right or the good.

Moral skeptics maintain that we do not have moral knowledge. Traditionally they haven’t argued via skeptical hypotheses like those provided by perceptual skeptics about the external world, such as Descartes’ deceiving demon. But some believe this can be done by appealing to hypotheses like moral nihilism. Moreover, some claim that skeptical hypotheses have special force in the moral case. But I argue that skeptics have failed to specify an adequate skeptical scenario, which reveals a general lesson: such arguments are not (...) a promising avenue for moral skeptics to take. They’re ultimately weaker when applied to morality compared to perception. (shrink)

Recent empirical research seems to show that emotions play a substantial role in moral judgment. Perhaps the most important line of support for this claim focuses on disgust. A number of philosophers and scientists argue that there is adequate evidence showing that disgust significantly influences various moral judgments. And this has been used to support or undermine a range of philosophical theories, such as sentimentalism and deontology. I argue that the existing evidence does not support such arguments. At best it (...) suggests something rather different: that moral judgment can have a minor emotive function, in addition to a substantially descriptive one. (shrink)

We present a unified empirical and philosophical account of moral consistency reasoning, a distinctive form of moral reasoning that exposes inconsistencies among moral judgments about concrete cases. Judgments opposed in belief or in emotion and motivation are inconsistent when the cases are similar in morally relevant respects. Moral consistency reasoning, we argue, regularly shapes moral thought and feeling by coordinating two systems described in dual process models of moral cognition. Our empirical explanation of moral change fills a gap in the (...) empirical literature, making psychologically plausible a defensible new model of justified moral change and a hybrid theory of moral judgment.

Provides an overview of empirical research relevant to philosophical questions about moral thought, feeling, reasoning, and motivation.

Altruism in Humans takes a hard-science look at the possibility that we humans have the capacity to care for others for their sakes rather than simply for our own. Based on an extensive series of theory-testing laboratory experiments conducted over the past 35 years, this book details a theory of altruistic motivation, offers a comprehensive summary of the research designed to test the empathy-altruism hypothesis, and considers the theoretical and practical implications of this conclusion. Authored by the world's preeminent scholar (...) on altruism, this landmark work is an authoritative scholarly resource on the theory surrounding altruism and its potential contribution to better interpersonal relations and a better society.

It has often been suggested that people's ordinary understanding of morality involves a belief in objective moral truths and a rejection of moral relativism. The results of six studies call this claim into question. Participants did offer apparently objectivist moral intuitions when considering individuals from their own culture, but they offered increasingly relativist intuitions considering individuals from increasingly different cultures or ways of life. The authors hypothesize that people do not have a fixed commitment to moral objectivism but instead tend (...) to adopt different views depending on the degree to which they consider radically different perspectives on moral questions.

Provides an overview of the theory of psychological egoism—the thesis that we are all ultimately motivated by self-interest. Philosophical arguments for and against the view are considered as well as some empirical evidence.

Many prominent accounts of free will and moral responsibility make use of the idea that agents can be responsive to reasons. Call such theories Reasons accounts. In what follows, I consider the tenability of Reasons accounts in light of situationist social psychology and, to a lesser extent, the automaticity literature. In the first half of this chapter, I argue that Reasons accounts are genuinely threatened by contemporary psychology. In the second half of the paper I consider whether such threats can (...) be met, and at what cost. Ultimately, I argue that Reasons accounts can abandon some familiar assumptions, and that doing so permits us to build a more empirically plausible picture of our agency. (shrink)

[Emerging Scholar Prize Essay for Spindel Supplement] Some philosophers and psychologists have evaluated psychological egoism against recent experimental work in social psychology. Dan Batson (1991; forthcoming), in particular, argues that empathy tends to induce genuinely altruistic motives in humans. However, some argue that there are egoistic explanations of the data that remain unscathed. I focus here on some recent criticisms based on the idea of self-other merging or "oneness," primarily leveled by Robert Cialdini and his collaborators (1997). These authors argue (...) that the putatively altruistic subjects are acting on ultimately egoistic motives because empathic feelings for someone in distress tend to cause them to blur the distinction between themselves and the other. Employing a conceptual framework for the debate, I argue that the self-other merging explanation fails to explain the empathy-helping relationship on primarily non-empirical grounds, regardless of the empirical results Cialdini and colleagues report.

Evolutionary debunking arguments are arguments that appeal to the evolutionary origins of evaluative beliefs to undermine their justification. This paper aims to clarify the premises and presuppositions of EDAs—a form of argument that is increasingly put to use in normative ethics. I argue that such arguments face serious obstacles. It is often overlooked, for example, that they presuppose the truth of metaethical objectivism. More importantly, even if objectivism is assumed, the use of EDAs in normative ethics is incompatible with a (...) parallel and more sweeping global evolutionary debunking argument that has been discussed in recent metaethics. After examining several ways of responding to this global debunking argument, I end by arguing that even if we could resist it, this would still not rehabilitate the current targeted use of EDAs in normative ethics given that, if EDAs work at all, they will in any case lead to a truly radical revision of our evaluative outlook.

Roughly, psychological egoism is the thesis that all of a person's intentional actions are ultimately self-interested in some sense; psychological altruism is the thesis that some of a person's intentional actions are not ultimately self-interested, since some are ultimately other-regarding in some sense. C. Daniel Batson and other social psychologists have argued that experiments provide support for a theory called the "empathy-altruism hypothesis" that entails the falsity of psychological egoism. However, several critics claim that there are egoistic explanations of the (...) data that are still not ruled out. One of the most potent criticisms of Batson comes from Elliott Sober and David Sloan Wilson. I argue for two main theses in this paper: (1) we can improve on Sober and Wilson’s conception of psychological egoism and altruism, and (2) this improvement shows that one of the strongest of Sober and Wilson's purportedly egoistic explanations is not tenable. A defense of these two theses goes some way toward defending Batson‘s claim that the evidence from social psychology provides sufficient reason to reject psychological egoism. (shrink)

In defending his interest-relative account of knowledge in Knowledge and Practical Interests (2005), Jason Stanley relies heavily on intuitions about several bank cases. We experimentally test the empirical claims that Stanley seems to make concerning our common-sense intuitions about these bank cases. Additionally, we test the empirical claims that Jonathan Schaffer seems to make in his critique of Stanley. We argue that our data impugn what both Stanley and Schaffer claim our intuitions about such cases are. To account for these (...) results, one must develop a better conception of the connection between a subject's interests and her body of knowledge than those offered by Stanley and Schaffer.

Jesse Prinz argues that recent work in philosophy, neuroscience, and anthropology supports two radical hypotheses about the nature of morality: moral values are based on emotional responses, and these emotional responses are inculcated by culture, not hard-wired through natural selection. In the first half of the book, Jesse Prinz defends the hypothesis that morality has an emotional foundation. Evidence from brain imaging, social psychology, and psychopathology suggest that, when we judge something to be right or wrong, we are merely expressing (...) our emotions. Prinz argues that these emotions do not track objective features of reality; rather, the rightness and wrongness of an act consists in the fact that people are disposed to have certain emotions towards it. In the second half of the book, he turns to a defense of moral relativism. Moral facts depend on emotional responses, and emotional responses vary from culture to culture. Prinz surveys the anthropological record to establish moral variation, and he draws on cultural history to show how attitudes toward practices such as cannibalism and marriage change over time. He also criticizes evidence from animal behavior and child development that has been taken to support the claim that moral attitudes are hard-wired by natural selection. Prinz concludes that there is no single true morality, but he also argues that some moral values are better than others; moral progress is possible. Throughout the book, Prinz relates his views to contemporary and historical work in philosophical ethics. His views echo themes in the writings of David Hume and Friedrich Nietzsche, but Prinz supports, extends, and revises these classic theories using the resources of cutting-edge cognitive science. The Emotional Construction of Morals will stimulate and challenge anyone who is curious about the nature and origin of moral values. (shrink)

Nomy Arpaly rejects the model of rationality used by most ethicists and action theorists. Both observation and psychology indicate that people act rationally without deliberation, and act irrationally with deliberation. By questioning the notion that our own minds are comprehensible to us--and therefore questioning much of the current work of action theorists and ethicists--Arpaly attempts to develop a more realistic conception of moral agency.

The phenomenon of persistent ethical disagreement is often cited in connection with the question of whether there is any ‘‘absolute’’ morality, or whether, instead, morality is in some sense merely ‘‘a matter of personal opinion’’. Citing disagreement, many people who hold strong views about controversial issues such as the permissibility of abortion, eating meat, or the death penalty deny that these views are anything more than ‘‘personal beliefs’’. But while there might be inconsistencies lurking in this position, it is not (...) obviously at fault for according the facts about disagreement some epistemic weight. This paper addresses the question of whether and to what extent moral disagreement undermines moral knowledge. The most familiar arguments from disagreement in the literature purport to establish conclusions about the metaphysics of morality: that there are no moral facts, or that there are no moral properties, or that the moral facts are relative rather than absolute. Of course, the conclusions of some such metaphysical arguments might be perfectly consistent with the existence of considerable moral knowledge. For example, even if there is some successful argument from disagreement to the conclusion that moral facts are relative rather than absolute, this might very well be consistent with our having just as much moral knowledge as we..

Perry argues that certain sorts of indexicals are 'essential', in the sense that they cannot be eliminated in favor of descriptions. This paper also introduces the influential idea that certain sorts of indexicals play a special role in thought, and have a special connection to action.

To desire something is a condition familiar to everyone. It is uncontroversial that desiring has something to do with motivation, something to do with pleasure, and something to do with reward. Call these "the three faces of desire." The standard philosophical theory at present holds that the motivational face of desire presents its unique essence--to desire a state of affairs is to be disposed to act so as to bring it about. A familiar but less standard account holds the hedonic (...) face of desire to reveal to true nature of desire. In this view, to desire something is to tend to pleasure if it seems that the desired state of affairs has been achieved, or displeasure if it seems otherwise, thus tying desire to feelings instead of actions. In Three Faces of Desire, Schroeder goes beyond actions and feelings to advance a novel and controversial theory of desire that puts the focus on desire's neglected face, reward. Informed by contemporary science as much as by the philosophical tradition, Three Faces of Desire discusses recent scientific discoveries that tell us much about the way that actions and feelings are produced in the brain. In particular, recent experiments reveal that a distinctive system is responsible for promoting action, on the one hand, and causing feelings of pleasure and displeasure, on the other. This system, the brain's reward system, is the causal origin of both action and feeling, and is the key to understanding the nature of desire. (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)

Disgust originated as an evolutionary adaptation for avoiding disease, but it has since infiltrated morality. Many philosophers are skeptical of moral disgust. Skeptics argue that disgust is unreliable and harmful, and that we should eliminate or minimize feelings of disgust in moral thought. However, these arguments are unsuccessful. They do not show that disgust is more problematic than other emotions implicated in morality. Moreover, empirical research suggests that disgust supports important norms and values. Disgust is frequently elicited by “reciprocity violations,” (...) i.e., acts of cheating, dishonesty, and exploitation. The emotion is a fitting response because it accurately reflects the ability of these moral wrongs to pollute and to circulate. Repurposing its original functions, moral disgust motivates social exclusion, tracks the spread of immorality, and acts as a signaling system to coordinate sanctioning. Instead of expunging ourselves of moral disgust, then, we should seek to understand its virtues and its vices. (shrink)

This book defends the Humean Theory of Motivation, according to which desire drives all action and practical reasoning. -/- Desire motivates us to pursue its object. It makes thoughts of its object pleasant. It focuses attention on its object. Its effects are amplified by vivid representations of its object. These aspects of desire explain why motivation usually accompanies moral belief, how intentions shape our plans, how we exercise willpower, what human selves are, how action can express emotion, why we procrastinate, (...) and how we daydream. The Humean Theory also suggests a new account of moral judgment that upholds objectivity while understanding moral concepts in terms of our feelings. (shrink)

Psychopaths are renowned for their immoral behavior. They are ideal candidates for testing the empirical plausibility of moral theories. Many think the source of their immorality is their emotional deficits. Psychopaths experience no guilt or remorse, feel no empathy, and appear to be perfectly rational. If this is true, sentimentalism is supported over rationalism. Here, I examine the nature of psychopathic practical reason and argue that it is impaired. The relevance to morality is discussed. I conclude that rationalists can explain (...) the moral deficits of psychopaths as well as sentimentalists. In the process, I identify psychological structures that underpin practical rationality.

Is the science of moral cognition usefully modelled on aspects of Universal Grammar? Are human beings born with an innate 'moral grammar' that causes them to analyse human action in terms of its moral structure, with just as little awareness as they analyse human speech in terms of its grammatical structure? Questions like these have been at the forefront of moral psychology ever since John Mikhail revived them in his influential work on the linguistic analogy and its implications for jurisprudence (...) and moral theory. In this seminal book, Mikhail offers a careful and sustained analysis of the moral grammar hypothesis, showing how some of John Rawls' original ideas about the linguistic analogy, together with famous thought experiments like the trolley problem, can be used to improve our understanding of moral and legal judgement.

Richard Holton provides a unified account of intention, choice, weakness of will, strength of will, temptation, addiction, and freedom of the will. Drawing on recent psychological research, he argues that, rather than being the pinnacle of rationality, the central components of the will are there to compensate for our inability to make or maintain sound judgments. Choice is understood as the capacity to form intentions even in the absence of judgments of what action is best. Weakness of will is understood (...) as the failure to maintain an intention, or more specifically, a resolution, in the face of temptation--where temptation typically involves a shift in judgment as to what is best, or in the case of addiction, a disconnection between what is judged best and what is desired. Strength of will is the corresponding ability to maintain a resolution, an ability that requires the employment of a particular faculty or skill. Finally, the experience of freedom of the will is traced to the experiences of forming intentions, and of maintaining resolutions, both of which require effortful activity from the agent. (shrink)

Carruthers argues that knowledge of our own propositional attitudes is achieved by the same mechanism used to attain knowledge of other people's minds. This seems incompatible with "privileged access"---the idea that we have more reliable beliefs about our own mental states, regardless of the mechanism. At one point Carruthers seems to suggest he may be able to maintain privileged access, because we have additional sensory information in our own case. We raise a number of worries for this suggestion, concluding that (...) Carruthers's new theory cannot clearly preserve the superior reliability of our beliefs about our own attitudes. (shrink)
