Empirical moral psychology is sometimes dismissed as normatively insignificant because it plays no decisive role in settling ethical disputes. But that conclusion, even if it is valid for normative ethics, does not extend to bioethics. First, in contrast to normative ethics, bioethics can legitimately proceed from a presupposed moral framework. Within that framework, moral psychology can be shown to play four significant roles: it can improve bioethicists’ understanding of the decision situation, the origin and legitimacy of their moral concepts, efficient (...) options for implementing decisions, and how to change and improve some parts of their moral framework. Second, metaethical considerations suggest that moral psychology may lead to the radical revision of entire moral frameworks and thus prompt the radical revision of entire moral frameworks in bioethics. However, I show that bioethics must either relinquish these radical implications of moral psychology and accept that there are limits to progress in bioethics based on moral psychology or establish an epistemic framework that guides radical revision.

Physicist Sean Carroll has developed a new theory of the fundamental nature of reality, which he calls “Poetic Naturalism,” with the stated goal of developing a theory of what is real that is consistent with the findings of natural science. Carroll claims to prove that morality cannot be seen as objectively true. This essay argues that Carroll's conclusion is not convincing; there is no good reason to reject moral objectivity within a purely naturalistic worldview.

Ethical theory often starts with our intuitions about particular cases and tries to uncover the principles that are implicit in them; work on the ‘trolley problem’ is a paradigmatic example of this approach. But ethicists are no longer the only ones chasing trolleys. In recent years, psychologists and neuroscientists have also turned to study our moral intuitions and what underlies them. The relation between these two inquiries, which investigate similar examples and intuitions, and sometimes produce parallel results, is puzzling. Does (...) it matter to ethics whether its armchair conclusions match the psychologists’ findings? I argue that reflection on this question exposes psychological presuppositions implicit in armchair ethical theorising. When these presuppositions are made explicit, it becomes clear that empirical evidence can (and should) play a positive role in ethical theorising. Unlike recent assaults on the armchair, the argument I develop is not driven by a naturalist agenda, or meant to cast doubt on the reliability of our moral intuitions; on the contrary, it is even compatible with non-naturalism, and takes the reliability of intuition as its premise. The argument is rather that if our moral intuitions are reliable, then psychological evidence should play a surprisingly significant role in the justification of moral principles. (shrink)

According to Joshua Greene’s influential dual process model of moral judgment, different modes of processing are associated with distinct moral outputs: automatic processing with deontological judgment, and controlled processing with utilitarian judgment. This paper aims to clarify and assess Greene’s model. I argue that the proposed tie between process and content is based on a misinterpretation of the evidence, and that the supposed evidence for controlled processing in utilitarian judgment is actually likely to reflect generic deliberation which, ironically, is incompatible (...) with a utilitarian outlook. This alternative proposal is further supported by the results of a recent neuroimaging study we have done. (shrink)

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

Neuroethics is typically conceived of as consisting of two traditions: the ethics of neuroscience and the neuroscience of moral judgment. However, recent work has sought to draw philosophical and ethical implications from the neuroscience of moral judgment. Such work, which concernsnormative moral neuroscience(NMN), is sufficiently distinct and complex to deserve recognition as a third tradition of neuroethics. Recognizing it as such can reduce confusion among researchers, eliminating conflations among both critics and proponents of NMN.This article identifies and unpacks some of (...) the most prominent goals, characteristic assumptions, and unique arguments in NMN and addresses some of the strongest objections NMN faces. The paper synthesizes these considerations into a set of heuristics, or loose discovery principles, that can help overcome obstacles in and attenuate resistance to NMN. These heuristics may simultaneously help identify those projects in NMN that are most likely to be fruitful and help fortify them. (shrink)

Critical reflection on the available neuropsychological evidence suggests that the roles of emotion and reason in moral judgment may not be distinct. This casts significant doubt on our current understanding of moral judgment, and therefore also on all philosophical theories based on that understanding. Most notably, it raises doubts about both sentimentalism and rationalism, which historically have often been treated as exclusive and exhaustive theories regarding the nature of moral concepts. As an alternative, I endorse pluralism with regard to the (...) emotional and rational nature of moral concepts. (shrink)

Neuroscience can relate to ethics and normative issues via the brain’s cognitive control network. This network accomplishes several executive processes, such as planning, task-switching, monitoring, and inhibiting. These processes allow us to increase the accuracy of our perceptions and our memory recall. They also allow us to plan much farther into the future, and with much more detail than any of our fellow mammals. These abilities also make us fitting subjects for responsibility claims. Their activity, or lack thereof, is at (...) the heart of culpability. For instance, planning to kill someone is strong evidence of what the law calls mens rea—a guilty mind. Claims about norms, or ethical “should” claims, express two-level propositions, directed at the behaving person at one level, and at that person’s mind and cognitive control network at another level. Thus, “People should stop themselves from hurting others,” is a claim about how people should behave and also a claim about how their cognitive control networks should behave—i.e., they should inhibit harmful behavior, or the intentions leading up to it. Planning is both an ability of the full person, and of that person’s mind. Neuroscience affirms the common notion, seen both in law and folk psychology, that what makes us guilty or culpable are certain events and states that exist in our minds. Overt behavior, including speech, is fallible evidence of these states and processes. Cases of negligence still involve the executive processes, but “negatively,” in that negligence results when certain types of executive activity fail to take place. (shrink)

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

What does global justice or charity requires us to give to other people? There is a large theoretical literature on this question. There is much less experimental work in political philosophy relevant to answering it. Perhaps for this reason, this literature has yet to have any major impact on theoretical discussions of global justice or charity. There is, however, some experimental research in behavioral economics that has helped to shape the field and a few relevant studies by political philosophers. This (...) paper reviews this research. Moreover, it argues that the little work that has been done can offer some methodological lessons to empirically engaged philosophers of many kinds. Finally, it suggests that there is reason for those interested in global ethics and charitable giving to consider doing new kinds of experimental and other empirical work in addition to traditional experimental philosophy.

Mind perception is the essence of moral judgment. Broadly, moral standing is linked to perceptions of mind, with moral responsibility tied to perceived agency, and moral rights tied to perceived experience. More specifically, moral judgments are based on a fundamental template of two perceived minds—an intentional agent and a suffering patient. This dyadic template grows out of the universal power of harm, and serves as a cognitive working model through which even atypical moral events are understood. Thus, all instances of (...) immorality are perceived to involve both blameworthy agents (i.e., acts) and suffering victims (i.e., consequences). Because moral cognition simultaneously concerns acts and consequences, theories which focus primarily on acts (i.e., deontology) or consequences (i.e., utilitarianism) do not accurately describe moral cognition. Indeed, the phenomenon of dyadic completion suggests that deontological and utilitarian concerns are not only simultaneously active, but also typically compatible and reinforcing: wrong acts have harmful consequences, and harmful consequences stem from wrong acts. The cognitive fusion of acts with consequences suggests that normative conflicts between deontology and utilitarianism are not reflected in everyday moral judgment. This in turn suggests that empirical conclusions drawn from moral dilemmas that pit utilitarianism against deontology—i.e., trolley problems—give an skewed account of moral cognition. (shrink)

In light of the magnitude of interpersonal harm and the risk of greater harm in the future, Ingmar Persson and Julian Savulescu have argued for pharmacological enhancement of moral behaviour. I discuss moral bioenhancement as a set of collective action problems. Psychotropic drugs or other forms of neuromodulation designed to enhance moral sensitivity would have to produce the same or similar effects in the brains of a majority of people. Also, a significant number of healthy subjects would have to participate (...) in clinical trials testing the safety and efficacy of these drugs, which may expose them to unreasonable risk. Even if the drugs were safe and effective, a majority of people would have to co-operate in a moral enhancement programme for such a project to succeed. This goal would be thwarted if enough people opted out and decided not to enhance. To avoid this scenario, Persson and Savulescu argue that moral enhancement should be compulsory rather than voluntary. But the collective interest in harm reduction through compulsory enhancement would come at the cost of a loss of individual freedom. In general, there are many theoretical and practical reasons for scepticism about the concept and goal of moral enhancement. (shrink)

El objetivo de este trabajo es mostrar las consecuencias prácticas de una autocomprensión positivista de la neuroética aplicada. Esta ética se ocupa de los impactos éticos y sociales derivados de la utilización de los hallazgos neurocientificos, en especial de las neurotecnologías. La intención es mostrar que para realizar esta tarea la neuroética debe superar el paradigma neuropositivista dominante que solo le conduce a la disolución del ámbito moral y, en el terreno práctico, al silencio cómplice ante los problemas surgidos en (...) la aplicación de las neurociencias. Para este fin daremos los siguientes pasos. En primer lugar, analizaremos los rasgos básicos de toda ética aplicada y desde ellos el origen y los objetivos de la neuroética aplicada. En segundo lugar, veremos cómo las investigaciones neuroéticas confunden el ámbito social con el ámbito moral, eliminando así de entrada toda perspectiva ética. Por último, ejemplificaremos las consecuencias prácticas de esta disolución en el caso de las políticas públicas, analizando el papel que puede cumplir y no cumple la neuroética aplicada frente al neuropoder generado por las neurotecnologías.

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

Imagine that an anthropologist returns from her study of a group of people and reports the following:They refuse to kill one person even to avert the death of all involved—including that one person;They won’t directly push someone to his death to save the lives of five others, but they will push a lever to kill him to save five others;They punish transgressors because it feels right, even when they expect the punishment to cause far more harm than good—and even when (...) the harm done by the punishment exceeds the harm done by the transgression being punished.The anthropologist’s report might lead us to conclude that these people are at least confused, and perhaps even dangerous.Here’s some bad news. Those people are us. Or so suggests recent research in experimental psychology and the neurosciences. This research indicates that our moral intuitions have a vaguely deontological character and they prompt us to make any number of judgments that appear arbitrary or otherwise unjustified, such ... -/- I contend that Greene partly misunderstands the practical implications of his own principles. If our ordinary moral judgments are to do the strategic work Greene wants them to do, he needs to endorse fullfledged Sidgwickian self-effacement for at least some areas of micro-level decision making. By the lights of some of Greene’s own arguments, people must accept the correctness—and not simply the usefulness—of the relevant intuitions in their personal conduct to satisfy utilitarian standards. I argue that removing utilitarian reasoning from micro-level decision making is consistent with Greene’s preferred strategy of using utilitarianism as a Bcommon currency^ for resolving moral conflict at the institutional level. To clarify upfront: the aim of this paper is to offer an internal criticism rather than to defend (e.g.,) the relevant empirical research, utilitarianism, self-effacement, and so on. I’m making an argument about where Greene’s own psychological and philosophical commitments should take him. (shrink)

We advance the thesis that the method of experimental economics can make significant contributions to normative, as opposed to descriptive, business ethics. We contend that there are two basic ways in which experimental economics may make this contribution, and we exemplify these ways by pointing to experimental support of social contract theory as rational foundation for business ethics. These two ways are: (1) adding psychological realism; and (2) testing some quasi-empirical assumptions present in normative theory. In order to make good (...) our methodological claim, we first describe the methodological rules of experimental economics, distinguishing this method from other behavioral business ethics approaches. We also contemplate the possible objection that empirical methods cannot bear on normative ethics because there is no way of bridging the gap between descriptive theory (how people behave) and normative theory (how people ought to behave).

Strategies for improving individual decision making have attracted attention from a range of disciplines. Surprisingly, neuroscience has been largely absent from this conversation, despite the fact that it has recently begun illuminating the neural bases of how and why we make decisions, and is poised for further such advances. Here we address empirical and normative questions about “nudging” through the lens of neuroscience. We suggest that the neuroscience of decision making can provide a framework for understanding how nudges work, and (...) how they can be improved. Towards this end, we first examine how nudges can be incorporated into a leading model of decision making supported by neurobiological data, and use the model to make predictions about the relative effectiveness of different classes of nudges. We then use the model to demonstrate how nudges can both infringe upon and promote autonomy. Finally, we explore the normative implications of the converging consensus from neuroscience and related fields that many everyday decisions are susceptible to covert external influences. (shrink)

:In this article, we begin by identifying three main neuroethical approaches: neurobioethics, empirical neuroethics, and conceptual neuroethics. Our focus is on conceptual approaches that generally emphasize the need to develop and use a methodological modus operandi for effectively linking scientific and philosophical interpretations. We explain and assess the value of conceptual neuroethics approaches and explain and defend one such approach that we propose as being particularly fruitful for addressing the various issues raised by neuroscience: fundamental neuroethics.

Empirical neuroethics models have always had normative ambitions. Older models attempted to debunk traditional moral theories, whereas newer models attempt to fit their empirical and normative claims with them. The issue of normative significance as it pertains to the use of social science methodology on moral intuitions remains open. This paper analyzes the Is/Ought gap and the empirical underpinnings of influential constructivist approaches in order to argue that the normative ambitions of empirical neuroethics models are not necessarily always misguided. The (...) author clarifies how legitimate normative implications can be dissociated from overreaches and argues that moral intuitions could be used as the factual basis for ethics by employing the distinction between natural facts, social facts, and social constructs. Ultimately, morality can be fruitfully studied and informed by natural and social sciences and, thorough ethical reflection, ought also to inform empirical research. (shrink)

This article proposes a novel integrative approach to moral judgment and a related model that could explain how unconscious heuristic processes are transformed into consciously accessible moral intuitions. Different hypothetical cases have been tested empirically to evoke moral intuitions that support principles from competing moral theories. We define and analyze the types of intuitions that moral theories and studies capture: those focusing on agents (A), deeds (D), and consequences (C). The integrative ADC approach uses the heuristic principle of “attribute substitution” (...) to explain how people make intuitive judgments. The target attributes of moral judgments are moral blameworthiness and praiseworthiness, which are substituted with more accessible and computable information about an agent's virtues and vices, right/wrong deeds, and good/bad consequences. The processes computing this information are unconscious and inaccessible, and therefore explaining how they provide input for moral intuitions is a key problem. We analyze social heuristics identified in the literature and offer an outline for a new model of moral judgment. Simple social heuristics triggered by morally salient cues rely on three distinct processes (role-model entity, action analysis, and consequence tallying—REACT) in order to compute the moral valence of specific intuitive responses (A, D, and C). These are then rapidly combined to form an intuitive judgment that could guide quick decision making. The ADC approach and REACT model can clarify a wide set of data from empirical moral psychology and could inform future studies on moral judgment, as well as case assessments and discussions about issues causing “deadlocked” moral intuitions.

In his article “Beyond Point-and-Shoot Morality,” Joshua Greene argues that the empirical findings of cognitive neuroscience have implications for ethics. Specifically, he contends that we ought to trust our manual, conscious reasoning system more than our automatic, emotional system when confronting unfamiliar problems; and because cognitive neuroscience has shown that consequentialist judgments are generated by the manual system and deontological judgments are generated by the automatic system, we ought to trust the former more than the latter when facing unfamiliar moral (...) problems. In the present article, I analyze one of the premises of Greene’s argument. In particular, I ask what exactly an unfamiliar problem is and whether moral problems can be classified as unfamiliar. After exploring several different possible interpretations of familiarity and unfamiliarity, I conclude that the concepts are too problematic to be philosophically compelling, and thus should be abandoned.

Joshua Greene has argued that the empirical findings of cognitive science have implications for ethics. In particular, he has argued (1) that people’s deontological judgments in response to trolley problems are strongly influenced by at least one morally irrelevant factor, personal force, and are therefore at least somewhat unreliable, and (2) that we ought to trust our consequentialist judgments more than our deontological judgments when making decisions about unfamiliar moral problems. While many cognitive scientists have rejected Greene’s dual-process theory of (...) moral judgment on empirical grounds, philosophers have mostly taken issue with his normative assertions. For the most part, these two discussions have occurred separately. The current analysis aims to remedy this situation by philosophically analyzing the implications of moral dilemma research using the CNI model of moral decision-making – a formalized, mathematical model that decomposes three distinct aspects of moral-dilemma judgments. In particular, we show how research guided by the CNI model reveals significant conceptual, empirical, and theoretical problems with Greene’s dual-process theory, thereby questioning the foundations of his normative conclusions.

This article is an attempt to take an overview of the current position of utilitarian theory. It begins by providing a definition of utilitarianism as it is found in the works of Bentham, Mill and Sidgwick. These authors are all interpreted as intuitionists. It is claimed that the main rivals to utilitarianism are egoism on the one hand, and reflective non-egoistic pluralism, as found in the work of Ross, on the other. The significance of disagreement between proponents of these views (...) is explained, and modern attempts to ground utilitarianism are found lacking. The article ends with a plea for history.

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

To develop more effective ethics education for cross-cultural and international engineering, a study was conducted to determine what Chinese engineering students have learned and think about ethics. Recent research shows traditional approaches to ethics education are potentially ineffective, but also points towards ways of improving ethical behaviors. China is the world’s most populous country, graduating and employing the highest number of STEM majors, although little empirical research exists about the ethical knowledge and perspectives of Chinese engineering students. When compared to (...) engineering students in the US, Chinese engineering students received less ethics education; the form of the education they did receive stressed virtue ethics or the development of moral character; conceive of ethics in contradistinction to the law, where ethics deals with matters of right and wrong not covered by legality. Based on these findings and research in moral psychology and behavioral ethics, recommendations are made for improving engineering ethics education both in China and abroad. (shrink)

In the last twenty years, there has been an enormous growth of scientific research concerning the process of human moral reasoning and moral intuitions. In contemporary descriptive ethics, three dominant approaches can be found – heuristic approach, dual-process theory, and universal moral grammar. Each of these accounts is based on similar empirical evidence combining findings from evolutionary biology, moral psychology, and neuroethics. Nevertheless, they come to different conclusions about the reliability of moral intuitions. The aim of this paper is to (...) critically investigate each of these approaches and compare them with recent scientific findings. Last chapter addresses implications of these findings for moral epistemology and normative ethics. The aim is to show that despite different interpretations of available data, we can reach a satisfying pragmatical conclusion which would be in compliance with the empirical evidence, yet it would not necessarily depend on it.

It is pointed out that, according to one of these, the philosophical reflection does not allow neuroscientific evidence to influence in any significant way the theoretical presupositions of that reflection. According to the second model, on the contrary, the role of the empirical component, essential to neuroethics, rather blocks the ethical and philosophical reflection. (shrink)

Neuromoral theorists are those who claim that a scientific understanding of moral judgment through the methods of psychology, neuroscience and related disciplines can have normative implications and can be used to improve the human ability to make moral judgments. We consider three neuromoral theories: one suggested by Gazzaniga, one put forward by Gigerenzer, and one developed by Greene. By contrasting these theories we reveal some of the fundamental issues that neuromoral theories in general have to address. One important issue concerns (...) whether the normative claims that neuromoral theorists would like to make are to be understood in moral terms or in non-moral terms. We argue that, on either a moral or a non-moral interpretation of these claims, neuromoral theories face serious problems. Therefore, neither the moral nor the non-moral reading of the normative claims makes them philosophically viable. (shrink)

Experimental philosophers have recently conducted surveys of folk judgements about a range of phenomena of interest to philosophy including knowledge, reference, and free will. Some experimental philosophers take these results to undermine the philosophical practice of appealing to intuitions as evidence. I consider several different replies to the suggestion that these results undermine philosophical appeal to intuition, both piecemeal replies which raise concerns about particular surveys, and more general replies. The general replies include the suggestions that the surveys consider the (...) wrong sort of judgement, or the wrong kind of judge, or that the results of the surveys do not generate scepticism about philosophical appeal to intuition in particular, but rather a more problematic and general scepticism. I argue that the last of these general replies is the most promising. To assess its merits, I consider the most developed account of how the survey results are supposed to raise sceptical problems specifically for philosophical appeal to intuition, that presented in Weinberg (Midwest Stud Philos XXXI:318–343, 2007). I argue that there are significant objections to Weinberg’s account. I conclude that, so far, experimental philosophers have failed to show how their survey results raise a sceptical challenge that applies to philosophical appeal to intuition in particular, rather than having a problematic, more general scope.

Joshua Greene and his colleagues have proposed a dual-process theory of moral decision-making to account for the effects of emotional responses on our judgments about moral dilemmas that ask us to contemplate causing direct personal harm. Early formulations of the theory contrast emotional and cognitive decision-making, saying that each is the product of a separable neural system. Later formulations emphasize that emotions are also involved in cognitive processing. I argue that, given the acknowledgement that emotions inform cognitive decision-making, a single-process (...) theory can explain all of the data that have been cited as evidence for Greene’s theory. The emotional response to the thought of causing harm may differ in degree, but not in kind, from other emotions influencing moral decision-making. (shrink)

Here I examine the major theories of ethical intuitions, focusing on the epistemic status of this class of intuitions. We cover self-evidence theory, seeming-state theory, and some of the recent contributions from experimental philosophy.

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.

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.

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)

Experimental ethicists investigate traditional ethical questions with non-traditional means, namely with the methods of the empirical sciences. Studies in this area have made heavy use of philosophical thought experiments such as the well-known trolley cases. Yet, the specific function of these thought experiments within experimental ethics has received little consideration. In this paper we attempt to fill this gap. We begin by describing the function of ethical thought experiments, and show that these thought experiments should not only be classified according (...) to their function but also according to their scope. On this basis we highlight several ways in which the use of thought experiments in experimental ethics can be philosophically relevant. We conclude by arguing that experimental philosophy currently only focuses on a small subcategory of ethical thought experiments and suggest a broadening of its research agenda. (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.

Many well-known arguments in the philosophy of mind use thought experiments to elicit intuitions about consciousness. Often, these thought experiments include mechanistic explanations of a systems’ behavior. I argue that when we understand a system as a mechanism, we are not likely to understand it as an agent. According to Arico, Fiala, Goldberg, and Nichols’ (2011) AGENCY Model, understanding a system as an agent is necessary for generating the intuition that it is conscious. Thus, if we are presented with a (...) mechanistic description of a system, we will be very unlikely to understand that system as conscious. Many of the thought experiments in the philosophy of mind describe systems mechanistically. I argue that my account of consciousness attributions is preferable to the “Simplicity Intuition” account proposed by David Barnett (2008) because it is more explanatory and more consistent with our intuitions. Still, the same conclusion follows from Barnett’s “Simplicity” account and from my own account: we should reassess the conclusions that have been drawn from many famous thought experiments. (shrink)

This is the most comprehensive book ever published on philosophical methodology. A team of thirty-eight of the world's leading philosophers present original essays on various aspects of how philosophy should be and is done. The first part is devoted to broad traditions and approaches to philosophical methodology. The entries in the second part address topics in philosophical methodology, such as intuitions, conceptual analysis, and transcendental arguments. The third part of the book is devoted to essays about the interconnections between philosophy (...) and neighbouring fields, including those of mathematics, psychology, literature and film, and neuroscience.

We chart how neuroscience and philosophy have together advanced our understanding of moral judgment with implications for when it goes well or poorly. The field initially focused on brain areas associated with reason versus emotion in the moral evaluations of sacrificial dilemmas. But new threads of research have studied a wider range of moral evaluations and how they relate to models of brain development and learning. By weaving these threads together, we are developing a better understanding of the neurobiology of (...) moral judgment in adulthood and to some extent in childhood and adolescence. Combined with rigorous evidence from psychology and careful philosophical analysis, neuroscientific evidence can even help shed light on the extent of moral knowledge and on ways to promote healthy moral development.

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)

In this chapter I critically discuss the dismissal of the philosophical significance of facts about human evolution and historical development in the work of W. D Ross. I address Ross’s views about the philosophical significance of the emerging human sciences of his time in two of his main works, namely The Right and the Good and The Foundations of Ethics. I argue that the debate between Ross and his chosen interlocutors (Herbert Spencer, Emile Durkheim and Lucien Levy-Bruhl) shows striking similarities (...) with parallel debates in contemporary moral philosophy.
