Neuroscience of Ethics

The main message of Neuroethics is that neuroscience forces us to reconceptualize human agency as marvelously diverse and flexible. Free will can arise from unconscious brain processes. Individuals with mental disorders, including addiction and psychopathy, exhibit more agency than is often recognized. Brain interventions should be embraced with cautious optimism. Our moral intuitions, which arise from entangled reason and emotion, can generally be trusted. Nevertheless, we can and should safely enhance our brain chemistry, partly because motivated reasoning crops up in (...) everyday life and in the practice of neuroscience itself. Despite serious limitations, brain science can be useful in the courtroom and marketplace. Recognizing all this nuance leaves little room for anxious alarmism or overhype and urges an emphasis on neurodiversity. The result is a highly opinionated tour of neuroethics as an exciting field full of implications for philosophy, science, medicine, law, and public policy. (shrink)

People seem more divided than ever before over social and political issues, entrenched in their existing beliefs and unwilling to change them. Empirical research on mechanisms driving this resistance to belief change has focused on a limited set of well-known, charged, contentious issues and has not accounted for deliberation over reasons and arguments in belief formation prior to experimental sessions. With a large, heterogeneous sample (N = 3,001), we attempt to overcome these existing problems, and we investigate the causes and (...) consequences of resistance to belief change for five diverse and less contentious socio-political issues. After participants chose initially to support or oppose a given socio-political position, they were provided with reasons favoring their chosen position (affirming reasons), reasons favoring the other, unchosen position (conflicting reasons), or all reasons for both positions (reasons for both sides). Our results indicate that participants are more likely to stick with their initial decisions than to change them no matter which reasons are considered, and that this resistance to belief change is likely due to a motivated, biased evaluation of the reasons to support their initial beliefs (prior-belief bias). More specifically, they rated affirming reasons more favorably than conflicting reasons—even after accounting for reported prior knowledge about the issue, the novelty of the reasons presented, and the reported strategy used to make the initial decision. In many cases, participants who did not change their positions tended to become more confident in the superiority of their positions after considering many reasons for both sides. (shrink)

This Element offers a framework for exploring the methodological challenges of neuroethics. The aim is to provide a roadmap for the methodological assumptions, and related pitfalls, involved in the interdisciplinary investigation of the ethical and legal implications of neuroscientific research and technology. It illustrates these points via the debate about the ethical and legal responsibility of psychopaths. Argument and the conceptual analysis of normative concepts such as 'personhood' or 'human agency' is central to neuroethics. This Element discusses different approaches to (...) establishing norms and principles that regulate the practices addressed by neuroethics and that involve the use of such concepts. How to characterize the psychological features central to neuroethics, such as autonomy, consent, moral understanding, moral motivation, and control is a methodological challenge. In addition, there are epistemic challenges when determining the validity of neuroscientific evidence. (shrink)

The aim of this paper is to give an account of what it is to internalize a rule. I claim that internalization is the process of redistributing the burden of instruction from the teacher to the student. The process is complete when instruction is no longer needed, and the rule has reshaped perceptual classification of the circumstances in which it applies. Teaching a rule is the initiation of this process. We internalize rules by simulating instruction coming from someone else. Running (...) these simulations enables us to toggle between the perspective of the instructor and our own perspective. By doing this we coordinate our perspectives with that of the teacher. The account given here provides a deeper explanation of why internalizing a rule involves the dispositions and reactive attitudes proponents of Rule Consequentialism often say it does, why moral reflection is variably demanding, how intergenerational moral progress is made possible by our cognitive architectures, and why the adoption of a rule should be understood in terms of teaching that rule.

This chapter conceptually analyzes the post-traumatic stress injuries called moral injury, moral fatigue or exhaustion, and broken spirit. It then identifies two puzzles. First, soldiers sometimes sustain moral injury even from doing right actions. Second, they experience moral exhaustion from making decisions even where the morally right choice is so obvious that it shouldn’t be stressful to make it; and even where rightness of decision is so murky that no decision could be morally faulted. The injuries result of mistaken moral (...) self-evaluation. Methods of preventing and treating these injuries are defended, including training in self-forgiveness, moral off-loading of actions and decisions to persons and devices less likely to feel inappropriate guilt, and the use of drugs to prevent such guilt. The foregoing has been about moral injury erroneously resulting from the non-violation of a correct moral code. But the chapter then introduces the concept of moral pseudo-injury—felt moral injury that has in reality resulted from violation of a false moral code, so that no one has really been morally injured. This can be used as a method in warfighting. And since the injuries it produces are illusory, this would be morally superior to physical violence. For it causes less injury to its victims, and should cause less guilt in those who must inflict it. Historical precedents are considered. Finally, our enemies often use moral pseudo-injury against us, in the form of terrorist violence against civilians. Terrorism causes comparatively few harms, yet we mistakenly see it as more morally horrific than conventional combat that causes much worse loss of life among armed forces members. Here we need the nuancing and clarifying power of philosophy to restore a sense of proportion, thence to prevent or therapize the moral pseudo-injury we may experience from these sorts of attacks. (This is a pre-penultimate version of the published version, available from OUP at the external link, which contains minor variances. The paper was earlier known as "PTSD Weaponized: A Theory of Moral Injury"; that now superseded version is archived under "past conferences" on the Center for Ethics and the Rule of Law website.).

What ethical questions does neuroscience raise and help to answer? Neuroethics blends philosophical analysis with modern brain science to address central questions within this growing field: · Is free will an illusion? · Does brain stimulation impair a patient's autonomy? · Does having a mental disorder excuse bad behavior? · Is addiction a brain disease? · Should we trust our gut feelings in ethics and politics? · Should we alter our brains to become better people? · Is human reasoning bound (...) to be biased by our values? · Can brain science be trusted to read the minds of criminals and consumers? This book provides an opinionated tour through captivating cases and a close examination of the philosophical issues and scientific evidence. Joshua May's lively and accessible writing style makes it an indispensable resource for students and scholars in both the sciences and humanities. (shrink)

Философские, традиционные подходы к морали в основном основаны на метафизических и теологических концепциях и теориях. Среди традиционных концепций этики наиболее заметной является теория божественного повеления (DCT). Согласно DCT, Бог дает человечеству моральные основы через его творение и откровение. Мораль и божественность были неразделимы со времен самой далекой цивилизации. Эти концепции укладываются в теологические рамки и в основном принимаются большинством последователей трех авраамических традиций: иудаизма, христианства и ислама: наиболее значительной части человеческого населения. Теории Божественного повеления основываются на вере и откровении и (...) не подлежат строгой демонстрации. Противники концепции морали Божьего повеления, основанной на невозможности продемонстрировать свои метафизические и религиозные допущения, пытались (хотя и безуспешно) на протяжении многих веков преуменьшать ее значение. Они придерживались аргумента, что он не демонстрирует никаких материальных доказательств и логической согласованности и по этой причине не может быть рассмотрен в научных или философских целях. Это всего лишь убеждение, и оно должно пониматься при этом условии. Помимо этих крайних противоположностей, многие другие концепции противоречат теориям Божественного повеления, так или иначе, частично или полностью. От классической греческой философии до наших дней многие философы и социологи утверждают, что мораль — это всего лишь конструкция, и поэтому она культурно относительна и обусловлена культурой. Однако это вызывает множество дальнейших дискуссий и ставит перед собой задачу определить важность культуры, какие элементы культуры являются морально определяющими, и, наконец, пределы этой относительности. Моральный детерминизм утверждает, что все, что связано с поведением человека, включая мораль, определяется таким образом, что свобода воли перестает существовать. Совсем недавно современные мыслители утверждали, что существует строгая наука о морали. Однако, несмотря на объяснение множества фактов и доказательств, один только научный метод не может пролить свет на все содержание и значение этики в целом. Понимание морали требует более широкого восприятия и согласия среди философов, чего они так и не достигли. Эти вопросы имеют множество различных конфигураций в зависимости от каждого философского направления и начинают сложный анализ и бесконечные дебаты, если многие из них противоречат друг другу. Вселенная и атмосфера, которые включает в себя это исследование, являются хозяевами всех этих концептуальных конфликтов, наблюдаемых с объективной и эволюционной точки зрения. Однако, несмотря на эти обстоятельства и их внутреннюю важность, эти вопросы далеки от методологического подхода аналитического обсуждения объективной морали, которое, по сути, является целью и областью действия этой работы. Мы должны кратко рассмотреть эти выдающиеся традиционные теории, потому что в этой работе проводится сравнительное исследование, и их предположения, по крайней мере, глубоко отличаются от всех традиционных теорий. Следовательно, становится необходимым предлагать читателю прямые и конкретные элементы сравнения для обоснованной критики без прерывания исследований. Но даже если мы пересмотрим традиционные теории для этой сравнительной и критической цели изложения, они все равно останутся в стороне от наших основных проблем как „чужеродная материя". Цель этой работы состоит в том, чтобы продемонстрировать существование и значение доисторических моральных архетипов — архетипов, вытекающих из фундаментальных социальных потребностей и борьбы за выживание — для определения сущностной основы этики, их агрегации в коллективном бессознательном и, следовательно, для определения того, что такое этика. Эти архетипы определяют эволюционную социальную модель человека. Является ли это мета этической позицией? Да, это так. Кроме того, как и в любой мета этической аргументации, мы должны тщательно искать наилучшие и наиболее правильные пути, предлагаемые аналитической философией. Эта работа была призвана обоснованно продемонстрировать, что мораль не является культурным продуктом цивилизованных людей или современных обществ. Несмотря на многочисленные культурные относительные объединения и вычитания, основные основы являются архетипическими и никогда не менялись структурно. Это рассуждение приводит к тому, что мораль является первым атрибутом „Homo sapiens"; это не собственность или случайность: она объединяет человеческое существо и является частью онтологической человеческой идентичности. Человеческие явления — это непрерывный процесс, который играет свою роль между случайной решимостью и свободной волей, и мы должны спросить, как зародилась мораль и как она пришла к нам в настоящее время.

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)

The urgent need for solutions to critical environmental challenges is well attested, but often environmental problems are understood as fundamentally collective action problems. However, to solve to these problems, there is also a need to change individual behavior. Hence, there is a pressing need to inculcate in individuals the environmental virtues — virtues of character that relate to our environmental place in the world. We propose a way of meeting this need, by the judicious, safe, and controlled administration of “classic” (...) psychedelic drugs as a way to catalyze the development of environmental virtues – a form of moral bio-enhancement. Recent evidence shows that psychedelics can be given safely in controlled environments, and can induce vivid experiences of unity and connectedness. These experiences, in turn, can durably increase feelings of nature-relatedness and pro-environmental behaviors. Therefore, we argue that responsible psychedelic use can reliably catalyze the development of a key environmental virtue known as living in place. This is a “master environmental virtue” that subsumes the qualities of respect for nature, proper humility, and aesthetic wonder and awe. Our account advances the environmental virtues debate by introducing a relevant practical proposal, and advances the psychedelic moral enhancement debate by providing a much-needed conceptual framework.

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.

Dubljević and company’s proposed approach for incorporating a socio-political perspective into neuroethics has clear potential to help mitigate the effects of research ‘hype’ relating to neuroethics. Their approach serves as a social regulation meant to improve the realizability of neuroethics research. Drawing on Dubljević et al. s suggestion, we consider how incorporating a socio-political perspective in other scientific disciplines could help the scientific community as a whole move beyond the infamous ‘reproducibility crisis’ in science. The reproducibility crisis is a concern (...) in science stemming from the revelation that most scientific results are difficult, or impossible, to replicate (Frias-Navarro et al., 2020). By applying the four principles proposed by Dubljević et al., the scientific community can avoid many of the pitfalls that have led to the reproducibility crisis, such as the file drawer effect, a publication bias preventing negative results from being published, or the publish-or-perish culture - the pressure for scientists to publish highly influential papers in high impact journals in order to keep their funding (Rosenthal, 1979; Begley & Ioannidis, 2015). As such, we argue that, in its final form, this socio-political framework begs for true open science, wherein systematically sharing data would enable enlightened policymaking by showing a picture closer to the ground-level realities of scientific research.

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.

Cognitive science poses a variety of philosophical questions. In this forthcoming volume, leading researchers debate five core questions in the Philosophy of Cognitive Science: Is Universal Grammar required to explain our linguistic capacities? Are some of our concepts innate or are they all learned? What role do our bodies play in cognition? Can neuroscience help us understand the mind? Can cognitive science help us understand human morality? The volume contains two accessible essays on each topic, each advocating for an opposing (...) approach. (shrink)

We sometimes fail unwittingly to do things that we ought to do. And we are, from time to time, culpable for these unwitting omissions. We provide an outline of a theory of responsibility for unwitting omissions. We emphasize two distinctive ideas: (i) many unwitting omissions can be understood as failures of appropriate vigilance, and; (ii) the sort of self-control implicated in these failures of appropriate vigilance is valuable. We argue that the norms that govern vigilance and the value of self-control (...) explain culpability for unwitting omissions. (shrink)

Psychopathy is increasingly in the public eye. However, it is yet to be fully and effectively understood. Within the context of the DSM-IV, for example, it is best regarded as a complex family of disorders. The upside is that this family can be tightly related along common dimensions. Characteristic marks of psychopaths include a lack of guilt and remorse for paradigm case immoral actions, leading to the common conception of psychopathy rooted in affective dysfunctions. An adequate portrait of psychopathy is (...) much more complicated, however. Though some neural regions and corresponding functions are commonly indicated, they range across those responsible for action planning and learning, as well as emotional processes. Accordingly, a complete fine-grained map of all neural mechanisms responsible for psychopathy has not been realized, and even if it were, such a map would have limited utility outside of the context of surgical or chemical intervention. The utility of a neural-level understanding of psychopathy is further limited by the fact that it is only applicable in the clinical identification of individual subjects, and the neuro-chemical/biological correction of those subjects after they are positively identified as psychopaths. On the other hand, an information processing model of moral cognition provides for wider-ranging applications. The theoretical and practical implications for such a feasible working model of psychopathic personalities are assessed. Finally, this chapter raises the possibility of directed modification of social-environmental factors discouraging the development of psychopathic personalities in the first place, modifications which are also open to simulation and testing in terms of the same model of moral cognition.

This chapter analyses the prospects of using neuroimaging methods, in particular functional magnetic resonance imaging (fMRI), for philosophical purposes. To do so, it will use two case studies from the field of emotion research: Greene et al. (2001) used fMRI to uncover the mental processes underlying moral intuitions, while Lindquist et al. (2012) used fMRI to inform the debate around the nature of a specific mental process, namely, emotion. These studies illustrate two main approaches in cognitive neuroscience: Reverse inference and (...) ontology testing, respectively. With regards to Greene et al.’s study, the use of Neurosynth (Yarkoni 2011) will show that the available formulations of reverse inference, although viable a priori, seem to be of limited use in practice. On the other hand, the discussion of Lindquist et al.’s study will present the so far neglected potential of ontology-testing approaches to inform philosophical questions. (shrink)

This chapter examines the relevance of the cognitive science of morality to moral epistemology, with special focus on the issue of the reliability of moral judgments. It argues that the kind of empirical evidence of most importance to moral epistemology is at the psychological rather than neural level. The main theories and debates that have dominated the cognitive science of morality are reviewed with an eye to their epistemic significance.

In fMRI research, the goal of correcting for multiple comparisons is to identify areas of activity that reflect true effects, and thus would be expected to replicate in future studies. Finding an appropriate balance between trying to minimize false positives (Type I error) while not being too stringent and omitting true effects (Type II error) can be challenging. Furthermore, the advantages and disadvantages of these types of errors may differ for different areas of study. In many areas of social neuroscience (...) that involve complex processes and considerable individual differences, such as the study of moral judgment, effects are typically smaller and statistical power weaker, leading to the suggestion that less stringent corrections that allow for more sensitivity may be beneficial, but also result in more false positives. Using moral judgment fMRI data, we evaluated four commonly used methods for multiple comparison correction implemented in SPM12 by examining which method produced the most precise overlap with results from a meta-analysis of relevant studies and with results from nonparametric permutation analyses. We found that voxel-wise thresholding with family-wise error correction based on Random Field Theory provides a more precise overlap (i.e., without omitting too few regions or encompassing too many additional regions) than either clusterwise thresholding, Bonferroni correction, or false discovery rate correction methods.

The cases that Doris chronicles of confabulation are similar to perceptual illusions in that, while they show the interstices of our perceptual or cognitive system, they fail to establish that our everyday perception or cognition is not for the most part correct. Doris's account in general lacks the resources to make synchronic assessments of responsibility, partially because it fails to make use of knowledge now available to us about what is happening in the brains of agents.

John Harris recently argues that the moral bioenhancement proposed by Persson and Savulescu can damage moral agency by depriving the recipients of their freedom to fall (freedom to make wrongful choices) and therefore should not be pursued. The link Harris makes between moral agency and the freedom to fall, however, implies that all forms of moral enhancement, including moral education, that aim to make the enhancement recipients less likely to “fall” are detrimental to moral agency. In this paper, I present (...) a new moral agency-based critique against the moral bioenhancement program envisaged by Persson and Savulescu. I argue that the irresistible influences exerted by the bioenhancement program harms our capabilities for conducting accurate self-reflection and forming decisions that truly express our will, which subsequently undermine our moral agency.

_Why efforts to create a scientific basis of morality are doomed to fail_ In this illuminating book, James Davison Hunter and Paul Nedelisky recount the centuries-long, passionate quest to discover a scientific foundation for morality. The "new moral science" led by such figures as E.O. Wilson, Patricia Churchland and Joshua Greene is only the newest manifestation of an effort that has failed repeatedly. Though claims for its accomplishments are often wildly exaggerated, this new iteration has been no more successful than (...) its predecessors. Hunter and Nedelisky argue that in the end, science cannot tell us how we should live or why we should be good and not evil, and this is for both philosophical and scientific reasons. In the face of this failure, the new moral science has taken a surprising turn. Whereas earlier efforts sought to demonstrate what is right and wrong, the new moral scientists have concluded that right and wrong, because they are not amenable to scientific study, don’t actually exist. Their moral nihilism turns the science of morality into a social engineering project. If there is nothing moral for science to discover, the science of morality becomes, at best, a program to achieve arbitrary societal goals. Concise and rigorously argued, _Science and the Good _is a major critique of a would-be science that has gained too much influence in today’s public discourse, and an exposé of that project’s darker turn.

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)

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)

Common understandings of neuroethics, i.e., of its distinctive nature, are premised on two distinct sets of claims: (1) neuroscience can change views about the nature of ethics itself and neuroethics is dedicated to reaping such an understanding of ethics; (2) neuroscience poses challenges distinct from other areas of medicine and science and neuroethics tackles those issues. Critiques have rightfully challenged both claims, stressing how the first may lead to problematic forms of reductionism while the second relies on debatable assumptions about (...) the nature of bioethics specialization and development. Informed by philosophical pragmatism and our experience in neuroethics, we argue that these claims are ill-founded and should give way to pragmatist reconstructions. Namely, neuroscience, much like other areas of empirical research on morality, can provide useful information about the nature of morally problematic situations but it does not need to promise radical and sweeping changes to ethics based on neuroscientism. Furthermore, the rationale for the development of neuroethics as a specialized field need not to be premised on the distinctive nature of the issues it tackles or of neurotechnologies. Rather, it can espouse an understanding of neuroethics as both a scholarly and a practical endeavor dedicated to resolving a series of problematic situations raised by neurological and psychiatric conditions.

Safe-by-Design (SBD) frameworks for the development of emerging technologies have become an ever more popular means by which scholars argue that transformative emerging technologies can safely incorporate human values. One such popular SBD methodology is called Value Sensitive Design (VSD). A central tenet of this design methodology is to investigate stakeholder values and design those values into technologies during early stage research and development (R&D). To accomplish this, the VSD framework mandates that designers consult the philosophical and ethical literature to (...) best determine how to weigh moral trade-offs. However, the VSD framework also concedes the universalism of moral values, particularly the values of freedom, autonomy, equality trust and privacy justice. This paper argues that the VSD methodology, particularly applied to nano-bio-info-cogno (NBIC) technologies, has an insufficient grounding for the determination of moral values. As such, an exploration of the value-investigations of VSD are deconstructed to illustrate both its strengths and weaknesses. This paper also provides possible modalities for the strengthening of the VSD methodology, particularly through the application of moral imagination and how moral imagination exceed the boundaries of moral intuitions in the development of novel technologies.

A central source of support for expressivist accounts of normative discourse is the intimate relationship between normative judgment and motivation. Expressivists argue that normative judgments must be noncognitive, desire-like states in order to be so tightly linked with motivation. Normative statements are then construed as expressions of these noncognitive states. In this paper, I draw on dual-process models in cognitive psychology to respond to this argument. According to my proposal, normative judgments are ordinary beliefs that are typically produced by two (...) kinds of process: intuitive-affective processes and domain-general reasoning. When produced by the first kind of process, motivation and judgment tend to align. When produced by the second kind, motivation and judgment might not align. Since the first kind of process is the most common pathway of normative belief formation, normative judgments are typically accompanied by aligning motivation. This proposal enables cognitivists to explain the intimate link between normative judgment and motivation, thereby removing the major obstacle to interpreting normative statements truth-conditionally.

This paper addresses two specific and related questions the Buddhist neuroethics program raises for our traditional understanding of Buddhist ethics: Does affective neuroscience supply enough evidence that contempla- tive practices such as compassion meditation can enhance normal cognitive functioning? Can such an account advance the philosophical debate concerning freedom and determinism in a profitable direction? In response to the first question, I argue that dispositions such as empathy and altruism can in effect be understood in terms of the mechanisms that (...) regulate affective cognition. In response to the second question, I claim that moral agency is a type of achievement that comes with learning the norms of ethical con- duct, which are not tractable by specifically neurobiological mechanisms and processes (though, once learned, such norms would have their neural cor- relates when enacted).

Lying is one of the characteristic features of psychopathy, and has been recognized in clinical and diagnostic descriptions of the disorder, yet individuals with psychopathic traits have been found to have reduced neural activity in many of the brain regions that are important for lying. In this study, we examine brain activity in sixteen individuals with varying degrees of psychopathic traits during a task in which they are instructed to falsify information or tell the truth about autobiographical and non-autobiographical facts, (...) some of which was related to criminal behavior. We found that psychopathic traits were primarily associated with increased activity in the anterior cingulate, various regions of the prefrontal cortex, insula, angular gyrus, and the inferior parietal lobe when participants falsified information of any type. Associations tended to be stronger when participants falsified information about criminal behaviors. Although this study was conducted in a small sample of individuals and the task used has limited ecological validity, these findings support a growing body of literature suggesting that in some contexts, individuals with higher levels of psychopathic traits may demonstrate heightened levels of brain activity.

_The Routledge Handbook of Neuroethics_ offers the reader an informed view of how the brain sciences are being used to approach, understand, and reinvigorate traditional philosophical questions, as well as how those questions, with the grounding influence of neuroscience, are being revisited beyond clinical and research domains. It also examines how contemporary neuroscience research might ultimately impact our understanding of relationships, flourishing, and human nature. The _Handbook_ features easy-to-follow chapters that appear here for the first time in print and—written by (...) 61 key scholars and fresh voices—represent the wide range of viewpoints in neuroethics. The volume spotlights new technologies and historical articulations of key problems, issues, and concepts, and includes cross-referencing between chapters to highlight the complex interactions of concepts and ideas within neuroethics. These features enhance the _Handbook_’s utility by providing readers with a contextual map for different approaches to issues, and a guide to further avenues of interest. (shrink)

This paper considers, firstly, to what extent the administration of oxytocin can augment the capacity of empathy in human beings; and secondly, whether or not such practice ought to be allowed. In relation to the latter, the author develops an argument in favour of this intervention by virtue of its consistency with the belief that, if a therapeutic treatment is to be considered acceptable, it is essential that it maximizes the well-being of those affected and that it does not compromise (...) the autonomy of the patient. Having rejected several objections related to the nature of this intervention, the author finally questions its morality on the basis of a concern with its universalizability. (shrink)

Stimulated by a general salience of neuroscientific research and the declaration of neuroscience as one of the leading disciplines of the current century, a diversity of disciplines from the social sciences and the humanities have engaged in discussions about the role of the brain in various social and cultural phenomena. The general importance assigned to the brain in so many areas of academic and social life nowadays has been called the ‘neuroscientific turn’. One of the fields that gained particular attention (...) in this context is neuroethics. It is, however, not clear if neuroethics should be regarded simply as an indicator of a change toward a brain-centered anthropological outlook in Western societies or as an entity that itself plays a crucial role in the development and promotion of this outlook. In this chapter, we present two perspectives on the ‘neuroscientific turn’, sketch a landscape of neuroethics, and scrutinize the current state and development of neuroethics as one of the new fields at the intersection between the neurosciences and the humanities. We will ask to what extent neuroethics is itself a product or a booster of a cultural turn toward neuroscience and which interpretations of neuroscientific knowledge and which public expectations of the potential of neuroscience have actually been put to work in the formation of neuroethics. As our analysis underlines, the interactions of neuroscience and ethics in the field of neuroethics are complex and multidirectional. On the one hand, philosophical and anthropological discourse has favored certain theoretical assumptions about the role of the brain for human self-understanding. On the other hand, neuroscience has stimulated many discourses in ethical theory, as well as in society, of which neuroethics can be regarded as a recent derivative. Finally, neuroethics itself occasionally functions as an amplifier of the assumption that neuroscience provides relevant information to help us understand the nature of human morality and the nature of good social norms and institutions.

In many jurisdictions, an offender’s remorse is considered to be a relevant factor to take into account in mitigation at sentencing. The growing philosophical interest in the use of neurointerventions in criminal justice raises an important question about such remorse-based mitigation: to what extent should technologically facilitated remorse be honoured such that it is permitted the same penal significance as standard instances of remorse? To motivate this question, we begin by sketching a tripartite account of remorse that distinguishes cognitive, affective (...) and motivational elements of remorse. We then describe a number of neurointerventions that might plausibly be used to enhance abilities that are relevant to these different elements of remorse. Having described what we term the ‘moral value’ view of the justification of remorse-based mitigation, we then consider whether using neurointerventions to facilitate remorse would undermine its moral value, and thus make it inappropriate to honour such remorse in the criminal justice system. We respond to this question by claiming that the form of moral understanding that is incorporated into a genuinely remorseful response grounds remorse’s moral value. In view of this claim, we conclude by arguing that neurointerventions need not undermine remorse’s moral value on this approach, and that the remorse that such interventions might facilitate could also be authentic to the recipient of the neurointerventions that we discuss.

People maintain a positive identity in at least two ways: They evaluate themselves more favorably than other people, and they judge themselves to be better now than they were in the past. Both strategies rely on autobiographical memories. The authors investigate the role of autobiographical memories of lying and emotional harm in maintaining a positive identity. For memories of lying to or emotionally harming others, participants judge their own actions as less morally wrong and less negative than those in which (...) other people lied to or emotionally harmed them. Furthermore, people judge those actions that happened further in the past to be more morally wrong than those that happened more recently. Finally, for periods of the past when they believed that they were very different people than they are now, participants judge their actions to be more morally wrong and more negative than those actions from periods of their pasts when they believed that they were very similar to who they are now. The authors discuss these findings in relation to theories about the function of autobiographical memory and moral cognition in constructing and perceiving the self over time. (shrink)

In this article we critically review the neural mechanisms of moral cognition that have recently been studied via electroencephalography (EEG). Such studies promise to shed new light on traditional moral questions by helping us to understand how effective moral cognition is embodied in the brain. It has been argued that conflicting normative ethical theories require different cognitive features and can, accordingly, in a broadly conceived naturalistic attempt, be associated with different brain processes that are rooted in different brain networks and (...) regions. This potentially morally relevant brain activity has been empirically investigated through EEG-based studies on moral cognition. From neuroscientific evidence gathered in these studies, a variety of normative conclusions have been drawn and bioethical applications have been suggested. We discuss methodological and theoretical merits and demerits of the attempt to use EEG techniques in a morally significant way, point to legal challenges and policy implications, indicate the potential to reveal biomarkers of psychopathological conditions, and consider issues that might inform future bioethical work.

The present essay discusses the relationship between moral philosophy, psychology and education based on virtue ethics, contemporary neuroscience, and how neuroscientific methods can contribute to studies of moral virtue and character. First, the present essay considers whether the mechanism of moral motivation and developmental model of virtue and character are well supported by neuroscientific evidence. Particularly, it examines whether the evidence provided by neuroscientific studies can support the core argument of virtue ethics, that is, motivational externalism. Second, it discusses how (...) experimental methods of neuroscience can be applied to studies in human morality. Particularly, the present essay examines how functional and structural neuroimaging methods can contribute to the development of the fields by reviewing the findings of recent social and developmental neuroimaging experiments. Meanwhile, the present essay also considers some limitations embedded in such discussions regarding the relationship between the fields and suggests directions for future studies to address these limitations.

The present study aims to examine the relationship between the cortical midline structures (CMS), which have been regarded to be associated with selfhood, and moral decision making processes at the neural level. Traditional moral psychological studies have suggested the role of moral self as the moderator of moral cognition, so activity of moral self would present at the neural level. The present study examined the interaction between the CMS and other moral-related regions by conducting psycho-physiological interaction analysis of functional images (...) acquired while 16 subjects were solving moral dilemmas. Furthermore, we performed Granger causality analysis to demonstrate the direction of influences between activities in the regions in moral decision-making. We first demonstrate there are significant positive interactions between two central CMS seed regions—i.e., the medial prefrontal cortex (MPFC) and posterior cingulate cortex (PCC)—and brain regions associated with moral functioning including the cerebellum, brainstem, midbrain, dorsolateral prefrontal cortex, orbitofrontal cortex and anterior insula (AI); on the other hand, the posterior insula (PI) showed significant negative interaction with the seed regions. Second, several significant Granger causality was found from CMS to insula regions particularly under the moral-personal condition. Furthermore, significant dominant influence from the AI to PI was reported. Moral psychological implications of these findings are discussed. The present study demonstrated the significant interaction and influence between the CMS and morality-related regions while subject were solving moral dilemmas. Given that, activity in the CMS is significantly involved in human moral functioning. (shrink)

Joshua Greene argues that cognitive (neuro)science matters for ethics in two ways, the “direct route” and the “indirect route.” Greene illustrates the direct route with a debunking explanation of the inclination to condemn all incest. The indirect route is an updated version of Greene’s argument that dual-process moral psychology gives support for consequentialism over deontology. I consider each of Greene’s arguments, and I argue that neither succeeds. If there is a route from cognitive (neuro)science to ethics, Greene has not found (...) it. (shrink)

This paper brings together the social intuitionist view of the psychology of moral judgments developed by Jonathan Haidt, and the recent morphological rationalist position of Terry Horgan and Mark Timmons. I will end up suggesting that Horgan and Timmons have offered us a more plausible account of the psychology of moral judgment formation. But the view is not without its own difficulties. Indeed, one of them might prove to be quite serious, as it could support a form of skepticism about (...) understanding our own motivating reasons. (shrink)

This book argues that critics of consequentialism have not been able to make a successful and comprehensive case against all versions of consequentialism because they have been using the wrong methodology. This methodology relies on the crucial assumption that consequentialist theories share a defining characteristic. This text interprets consequentialism, instead, as a family resemblance term. On that basis, it argues quite an ambitions claim, viz. that all versions of consequentialism should be rejected, including those that have been created in response (...) to conventional criticisms. The book covers a number of classic themes in normative ethics, metaethics and, particularly, ethical methodology and also touches upon certain aspects of experimental moral philosophy. It is written in clear language and is analytic in its argumentative style. As such, the book should appeal to students, graduate students as well as professional academics with an interest in analytic moral philosophy. (shrink)

Some philosophers hold that the neuroscience of action is, in practice or in principle, incapable of touching debates in action theory and moral psychology. The role of desires in action, the existence of basic actions, and the like are topics that must be sorted out by philosophers alone: at least at present, and perhaps by the very nature of the questions. This paper examines both philosophical and empirical arguments against the relevance of neuroscience to such questions and argues that neither (...) succeeds. In practice, there is already a stable body of findings from neuroanatomy and neurophysiology that warrants attention. And as a matter of principle, the ‘causal map’ of action production derivable from these findings requires the study of action theorists and moral psychologists because every such philosopher has commitments to the shape of this causal map: commitments that might be in conflict with reality.

Neuroethics is the body of work exploring the ethical, legal, and social implications of neuroscience. This work can be separated into two rough categories. The neuroscience of ethics concerns a neuroscientific understanding of the brain processes that underpin moral judgment and behavior. The ethics of neuroscience, on the other hand, includes the potential impact advances in neuroscience may have on social, moral and philosophical ideas and institutions, as well as the ethical principles that should guide brain research, treatment of brain (...) disease, and cognitive enhancement. Central to the questions posed in neuroethics is the way in which neuroscience might impact our sense of self and personal responsibility, and our understanding the structure of moral judgments.

Joshua Greene has put forward the bold empirical hypothesis that deontology is a confabulation of moral emotions. Deontological philosophy does not steam from "true" moral reasoning, but from emotional reactions, backed up by post hoc rationalizations which play no role in generating the initial moral beliefs. In this paper, I will argue against the confabulation hypothesis. First, I will highlight several points in Greene’s discussion of confabulation, and identify two possible models. Then, I will argue that the evidence does not (...) illustrate the relevant model of deontological confabulation. In fact, I will make the case that deontology is unlikely to be a confabulation because alarm-like emotions, which allegedly drive deontological theorizing, are resistant to be subject to confabulation. I will end by clarifying what kind of claims can the confabulation data support. The upshot of the final section is that confabulation data cannot be used to undermine deontological theory in itself, and ironically, if one commits to the claim that a deontological justification is a confabulation in a particular case, then the data suggests that in general deontology has a prima facie validity.

In this article, I use science-fiction scenarios drawn from Dan Simmons’ “Hyperion Cantos” (Hyperion, The Fall of Hyperion, Endymion, The Rise of Endymion) to explore a cluster of issues related to the evolutionary history and neural bases of human moral cognition, and the moral desirability of improving our ability to make moral decisions by techniques of neuroengineering. I begin by sketching a picture of what recent research can teach us about the character of human moral psychology, with a particular emphasis (...) on highlighting the importance of our evolutionary background as social mammals. I then consider how the moral psychology of intelligent machines might differ from our own, and argue that the differences would depend on the extent to which their evolutionary background resembled our own. I offer two very different case studies—the “Technocore AIs” that have evolved from early, parasitic computer programs, and the mysterious “Shrike,” who travels backward through time. I close by looking at the character of Aenea, a messianic figure that is a joint descendant of humans and machines. I argue that while the sort of “moral enhancement” she represents is far beyond the scope of either contemporary neuroscience or artificial intelligence research, it nevertheless represents a worthwhile goal.

Ethical questions have traditionally been approached through conceptual analysis. Inspired by the rapid advance of modern brain imaging techniques, however, some ethical questions appear in a new light. For example, hotly debated trolley dilemmas have recently been studied by psychologists and neuroscientists alike, arguing that their findings can support or debunk moral intuitions that underlie those dilemmas. Resulting from the wedding of philosophy and neuroscience, neuroethics has emerged as a novel interdisciplinary field that aims at drawing conclusive relationships between neuroscientific (...) observations and normative ethics. A major goal of neuroethics is to derive normative ethical conclusions from the investigation of neural and psychological mechanisms underlying ethical theories, as well as moral judgments and intuitions. The focus of this article is to shed light on the structure and functioning of neuroethical arguments of this sort, and to reveal particular methodological challenges that lie concealed therein. We discuss the methodological problem of how one can—or, as the case may be, cannot—validly infer normative conclusions from neuroscientific observations. Moreover, we raise the issue of how preexisting normative ethical convictions threaten to invalidate the interpretation of neuroscientific data, and thus arrive at question-begging conclusions. Nonetheless, this is not to deny that current neuroethics rightly presumes that moral considerations about actual human lives demand empirically substantiated answers. Therefore, in conclusion, we offer some preliminary reflections on how the discussed methodological challenges can be met. (shrink)
