Neuroscience has dramatically increased understanding of how mental states and processes are realized by the brain, thus opening doors for treating the multitude of ways in which minds become dysfunctional. This book explores questions such as when is it permissible to alter a person's memories, influence personality traits or read minds? What can neuroscience tell us about free will, self-control, self-deception and the foundations of morality? The view of neuroethics offered here argues that many of our new powers to read (...) ,alter and control minds are not entirely unparalleled with older ones. They have, however, expanded to include almost all our social, political and ethical decisions. Written primarily for graduate students, this book will appeal to anyone with an interest in the more philosophical and ethical aspects of the neurosciences. (shrink)

A key component of research on human sentence processing is to characterize the processing difficulty associated with the comprehension of words in context. Models that explain and predict this difficulty can be broadly divided into two kinds, expectation‐based and memory‐based. In this work, we present a new model of incremental sentence processing difficulty that unifies and extends key features of both kinds of models. Our model, lossy‐context surprisal, holds that the processing difficulty at a word in context is proportional to (...) the surprisal of the word given a lossy memory representation of the context—that is, a memory representation that does not contain complete information about previous words. We show that this model provides an intuitive explanation for an outstanding puzzle involving interactions of memory and expectations: language‐dependent structural forgetting, where the effects of memory on sentence processing appear to be moderated by language statistics. Furthermore, we demonstrate that dependency locality effects, a signature prediction of memory‐based theories, can be derived from lossy‐context surprisal as a special case of a novel, more general principle called information locality.

In her paper, The case for physician assisted suicide: not proven, Bonnie Steinbock argues that the experience with Oregon’s Death with Dignity Act fails to demonstrate that the benefits of legalising physician assisted suicide outweigh its risks. Given that her verdict is based on a small number of highly controversial cases that will most likely occur under any regime of legally implemented safeguards, she renders it virtually impossible to prove the case for physician assisted suicide. In this brief paper, we (...) suggest some ways that may enable us to weigh the risks and benefits of legalisation more fairly and, hopefully, allow us to close the case for physician assisted suicide.

Self-control is a fundamental part of what it is to be a human being. It poses important philosophical and psychological questions about the nature of belief, motivation, judgment, and decision making. More immediately, failures of self-control can have high costs, resulting in ill-health, loss of relationships, and even violence and death, whereas strong self-control is also often associated with having a virtuous character. What exactly is self-control? If we lose control can we still be free? Can we be held responsible (...) for loss of self-control? -/- In this thorough and clearly written introduction to the philosophy of self-control, the authors examine and assess the following topics and questions: • The importance of self-control • What is self-control? • Self-control and the law of desire • Mechanisms of self-control • How is it possible to lose self-control? • Blameworthiness and (the loss of) self-control • Externalist self-control • Pathologies of self-control. -/- Combining philosophical analysis with surveys of the latest psychological research, and including chapter summaries, suggestions for further reading, and a glossary of key terms, Self-Control is essential reading for students of philosophy of mind and psychology, moral psychology, free will, and ethics. It will also be of interest to those in related fields such as psychology and cognitive science. (shrink)

Proponents of mechanistic explanation all acknowledge the importance of organization. But they have also tended to emphasize specificity with respect to parts and operations in mechanisms. We argue that in understanding one important mode of organization—patterns of causal connectivity—a successful explanatory strategy abstracts from the specifics of the mechanism and invokes tools such as those of graph theory to explain how mechanisms with a particular mode of connectivity will behave. We discuss the connection between organization, abstraction, and mechanistic explanation and (...) illustrate our claims by looking at an example from recent research on so-called network motifs.

In the wake of the spectacular success of Miranda Fricker's Epistemic Injustice, philosophers have paid a great deal of attention to testimonial injustice. Testimonial injustice occurs when recipients of testimony discount it in virtue of its source: usually, their social identity. The remedy for epistemic injustice is almost always listening better and giving greater weight to the testimony we hear, on most philosophers' implicit or explicit view. But Fricker identifies another kind of epistemic injustice: hermeneutical injustice. This kind of injustice (...) occurs when someone can't articulate their own experience or understand their situation for lack of the hermeneutical tools. There is a possible tension between these kinds of injustice, we suggest: sincere testimony may be misleading (may fail to identify significant harms the testfier is subject, or may fail to register its magnitude, or to categorize it as the kind of harm it is) in virtue of a lack of hermeneutical resources. This tension raises the possibility that there are situations in which experts - those who possess hermeneutical tools - may be able to correct the testimony of those who experience harms in virtue of their identity. In this paper, we identify possible cases in which epistemic injustice might be reduced through such correction: in which an increase in testimonial injustice might serve to decrease it in the longer run, for example. We also suggest how the obvious dangers of a too great readiness to see testimony as in need of expert correction might be mitigated, and how the expert might suggest corrections without ceasing to listen.

The widespread conviction that we are living in a post-truth era rests on two claims: that a large number of people believe things that are clearly false, and that their believing these things reflects a lack of respect for truth. In reality, however, fewer people believe clearly false things than surveys or social media suggest. In particular, relatively few people believe things that are widely held to be bizarre. Moreover, accepting false beliefs does not reflect a lack of respect for (...) truth. Almost everyone’s beliefs are explained by rationally warranted trust in some sources rather than others. This allows us to explain why people have false beliefs. (shrink)

The aim of this article is to argue, by example, for neuroethics as a new way of doing ethics. Rather than simply giving us a new subject matter—the ethical issues arising from neuroscience—to attend to, neuroethics offers us the opportunity to refine the tools we use. Ethicists often need to appeal to the intuitions provoked by consideration of cases to evaluate the permissibility of types of actions; data from the sciences of the mind give us reason to believe that some (...) of these intuitions are less reliable than others. I focus on the doctrine of double effect to illustrate my case, arguing that experimental results suggest that appeal to it might be question-begging. The doctrine of double effect is supposed to show that there is a moral difference between effects that are brought about intentionally and those that are merely foreseen; I argue that the data suggest that we regard some effects as merely foreseen only because we regard bringing them about as permissible. Appeal to the doctrine of double effect therefore cannot establish that there are such moral differences. (shrink)

Modeling is an important scientific practice, yet it raises significant philosophical puzzles. Models are typically idealized, and they are often explored via imaginative engagement and at a certain “distance” from empirical reality. These features raise questions such as what models are and how they relate to the world. Recent years have seen a growing discussion of these issues, including a number of views that treat modeling in terms of indirect representation and analysis. Indirect views treat the model as a bona (...) fide object, specified by the modeler and used to represent and reason about some portion of the concrete empirical world. On some indirect views, model systems are abstract entities, such as mathematical structures, while on other views they are concrete hypothetical things. Here I assess these views and offer a novel account of models. I argue that regarding models as abstracta results in some significant tensions with the practice of modeling, especially in areas where non-mathematical models are common. Furthermore, viewing models as concrete hypotheticals raises difficult questions about model-world relations. The view I argue for treats models as direct, albeit simplified, representations of targets in the world. I close by suggesting a treatment of model-world relations that draws on a recent work by Stephen Yablo concerning the notion of partial truth. (shrink)

The author comments on the article “The Neurobiology of Addiction: Implications for Voluntary Control of Behavior,‘ by S. E. Hyman. Hyman’s article suggests that addicted individuals have impairments in cognitive control of behavior. The author agrees with Hyman’s view that addiction weakens the addict’s ability to align his actions with his judgments. The author states that neuroethics may focus on brains and highlight key aspects of behavior but we still risk missing explanatory elements.

In recent years, researchers have tried to unpack the meaning of the term flexibility and test how different constructs of flexibility are associated with various psychopathologies. For example, it is apparent that high levels of flexibility allow individuals to adaptively cope and avoid psychopathology following traumatic events, but the precise nature of this flexibility is ambiguous. In this study we focus on two central constructs: cognitive flexibility – the ability to recognize and implement possible responses to a situation– and regulatory (...) flexibility – the ability to modulate emotional expression and experience across situations. We aim to explore the connection between cognitive and regulatory flexibility and evaluate their relative effect on PTSD symptoms. Trauma-exposed college students were assessed for cognitive and regulatory flexibility and current and lifetime PTSD symptoms. We predicted and found a relatively weak, yet significant, overlap between participants’ cognitive and regulatory flexibility. Importantly, while both cognitive and regulatory flexibility were associated with lifetime PTSD symptoms, only cognitive flexibility was associated with current PTSD symptoms. The findings illuminate the possible value of differentiating between constructs of flexibility in predicting short and long-term effects of traumatic exposure and may pave the ground for developing personalized intervention methods.

This book brings cutting edge neuroscience and psychology into dialogue with philosophical reflection to illuminate the loss of control experienced by addicts, and thereby cast light on ordinary agency and the way in which it sometimes goes wrong.

It is sometimes objected that we cannot adopt skepticism about moral responsibility, because the criminal justice system plays an indispensable social function. In this paper, I examine the implications of moral responsibility skepticism for the punishment of those convicted of crime, with special attention to recent arguments by Saul Smilansky. Smilansky claims that the skeptic is committed to fully compensating the incarcerated for their detention, and that this compensation would both be too costly to be practical and would remove the (...) deterrent function from incarceration. I argue that the skeptic is not committed to full compensation of the offender, and that the costs of such compensation would in any case be far smaller than Smilansky thinks. In fact, I claim, the costs of the criminal justice system to which the skeptic is committed might be very much lower than the costs – economic, social and moral – we currently pay as a consequence of our system of punishment.

The self-deceived are usually held to be moral responsible for their state. I argue that this attribution of responsibility makes sense only against the background of the traditional conception of self-deception, a conception that is now widely rejected. In its place, a new conception of self-deception has been articulated, which requires neither intentional action by self-deceived agents, nor that they possess contradictory beliefs. This new conception has neither need nor place for attributions of moral responsibility to the self-deceived in paradigmatic (...) cases. Accordingly, we should take the final step toward abandoning the traditional conception, and drop the automatic attribution of responsibility. Self-deception is simply a kind of mistake, and has no more necessary connection to culpability than have other intellectual errors. (shrink)

Recent findings in neuroscience, evolutionary biology and psychology seem to threaten the existence or the objectivity of morality. Moral theory and practice is founded, ultimately, upon moral intuition, but these empirical findings seem to show that our intuitions are responses to nonmoral features of the world, not to moral properties. They therefore might be taken to show that our moral intuitions are systematically unreliable. I examine three cognitive scientific challenges to morality, and suggest possible lines of reply to them. I (...) divide these replies into two groups: we might confront the threat, showing that it does not have the claimed implications for morality; or we might bite the bullet, accepting that the claims have moral implications, but incorporating these claims into morality. I suggest that unless we are able to bite the bullet, when confronted by cognitive scientific challenges, there is a real possibility that morality will be threatened. This fact gives us a weighty reason to adopt a metaethics that makes it relatively easy to bite cognitive scientific bullets. Moral constructivism, in one of its many forms, makes these bullets more palatable; therefore, the cognitive scientific challenges provide us with an additional reason to adopt a constructivist metaethics.

Children, even very young children, distinguish moral from conventional transgressions, inasmuch as they hold that the former, but not the latter, would still be wrong if there was no rule prohibiting them. Many people have taken this finding as evidence that morality is objective, and therefore universal. I argue that reflection on the phenomenon of imaginative resistance will lead us to question these claims. If a concept applies in virtue of the obtaining of a set of more basic facts, then (...) it is authority independent, and we therefore resist the attempts of authorities to claim that it does not apply. Thus, the moral/conventional distinction is a product of imaginative resistance to claims that a concept does not apply when its supervenience base is in place (or vice versa). All we can rightfully conclude from the fact that children are disposed to make the moral/conventional distinction is that our moral concepts belong to the class of authority-independent concepts. Though the set of basic facts in virtue of which an authority-independent concept obtains must be objective, the concept itself might be conventional, inasmuch as we could easily draw its boundaries wider or narrower, or fail to have a concept that corresponds to these properties at all.

In lieu of an abstract, here is a brief excerpt of the content:Norms, Conventions, and PsychopathsNeil Levy (bio)Keywordspsychopathy, morality, conventions, responsibilityI am grateful to my commentators for their provocative challenges to my claim that psychopaths ought to be excused moral responsibility for their wrongdoing owing to their (alleged) failure to grasp the moral/conventional distinction. I have learned from all the commentators—now, and in some cases in the past as well—and I am sincerely honored by their having taken my work (...) seriously enough to comment on it, even if only to take issue with it. In what follows, I shall attempt to reply to their main criticisms. As will shortly become clear, I do not here have the space for anything like adequate responses. Instead, I shall have to content myself with programmatic statements of how such responses might go. Let me admit at the outset that until the details of these responses are fully worked out, and the relevant empirical research conduced, I cannot be sure that the responses will succeed. Nevertheless, there are grounds for confidence, given the available data.Because there is some overlap between the criticisms, I shall address some of them—those of Blair, Nichols, and Vargas—by topic rather than by commentator, before turning to Mullen and Matravers.Is the Ability to Understand the Moral/Conventional Distinction a Necessary Condition of Aptness for Moral Responsibility?Blair, as well as Vargas and Nichols, suggests that an agent's knowing that an action is against the rules might be sufficient to ground responsibility for performing that action, even if the agent lacks the ability to draw the moral/conventional distinction. As Blair points out, we do not reserve blame only for those who violate moral rules. Blame, and sometimes punishments, are also meted out to those who violate merely conventional norms. Because psychopaths can understand conventional norms perfectly well, they may therefore seem to be appropriate targets of at least some kind of moral blame.But is it really the case that agents are (ever) blameworthy for violating conventional norms alone? Many philosophers, for instance when considering the morality of civil disobedience, have argued that conventional norms are typically backed by second-order moral norms. Hence, for many or all conventional norms, there is a (defeasible) moral obligation not to violate that norm, an obligation independent of the content of the conventional norm; it is because there are such second-order moral obligations that agents are blameworthy for violating conventional norms. [End Page 163] But if this is the case, then the fact that we sometimes blame agents for violating conventional norms is not evidence against the claim that the ability to grasp moral norms is a necessary condition of blameworthiness. There is no reason to think that psychopaths will find it any easier to grasp second-order moral norms than first-order (of course, they may understand that there are such things as second-order norms—norms concerning norms—but for them such norms will only be conventional). In fact, it might be more difficult to understand the moral force of second-order moral norms than first, inasmuch as the harms caused by violating such norms are emotional and not physical. Normal subjects invest (some) conventional norms with moral significance, and it is for this reason that we regard violations of such norms as apt to give rise to blame; lacking the ability to draw the moral/conventional distinction, psychopaths cannot invest such norms with moral significance. Once again, for them these norms are merely conventional, and they therefore fail to grasp the full significance of violating them.It might be objected that if conventional transgressions are (sometimes) backed up by second-order moral norms, children would not classify them as neatly as they do. They would misclassify some conventional norms as moral, insofar as they are backed up by second-order moral norms. They would therefore deny that violations of conventions are permissible on the say-so of an authority. There are two possible explanations of children's classifications, compatible with the suggestion that some conventions are backed by second-order moral norms. First, it may be that greater cognitive sophistication is required to grasp second-order moral norms than... (shrink)

In applied ethics, debates about responsibility have been relentlessly individualistic and synchronic, even as recognition has increased in both philosophy and psychology that agency is distributed across time and individuals. I therefore warmly welcome Brown and Savulescu’s analysis of the conditions under which responsibility can be shared and extended. By carefully delineating how diachronic and dyadic responsibility interact with the long-established control and epistemic conditions, they lay the groundwork needed for identifying how responsibility may be inter-individual and intra-individual. Unsurprisingly, I (...) don’t agree with every aspect of their rich account. I strongly suspect that the privileged place the individual continues to occupy in their taxonomy is a residue of the kind of internalist intuitions which dominate WEIRD thinking.1 2 However, I won’t pursue this line of thought here. Instead, I apply Brown and Savulescu’s analysis. Moving beyond the programmatic level at which they develop their account, I will show how it provides a basis for excusing many individuals, focusing not on the dyadic level but the diachronic. Most of the …. (shrink)

Several ethicists have argued that research trials and treatment programs that involve the provision of drugs to addicts are prima facie unethical, because addicts can’t refuse the offer of drugs and therefore can’t give informed consent to participation. In response, several people have pointed out that addiction does not cause a compulsion to use drugs. However, since we know that addiction impairs autonomy, this response is inadequate. In this paper, I advance a stronger defense of the capacity of addicts to (...) participate in the programs envisaged. I argue that it is only in certain circumstances that addicts find themselves choosing in ways that conflict with their genuine preferences. Research and treatment programs have none of the features that characterize choices in these autonomy-undermining circumstances, and there is therefore no reason to think that addicts lack the capacity to give informed consent to these programs.

I am to grateful to Geoff Keeling for his perceptive response1 to my paper.2 In this brief reply, I will argue that he does not succeed in his goal of showing that nudges to reason do not respect autonomy. At most, he establishes only that such nudges may threaten autonomy when used in certain ways and in certain circumstances. As I will show, this is not a conclusion that should give us grounds for particular concerns about nudges. Before turning to (...) this issue, let me correct some small issues of interpretation of my paper. Keeling takes me to be committed to three descriptive claims: that we have entered a post-truth era, that our problem with the rational assessment of evidence is explained by or stems from the backfire effect and that nudges to reason work by exploiting affective mechanisms. I am not committed to accepting any of these claims. …. (shrink)

This brief paper sketches the main theses of my recent book Bad Beliefs. The book defends the view that human cognition is more evidence responsive than most psychologists and naturalistic philosophers think. In particular, we are responsive to the abundant higher-order evidence that we encounter in experiments and in everyday life.

To the extent that indeterminacy intervenes between our reasons for action and our decisions, intentions and actions, our freedom seems to be reduced, not enhanced. Free will becomes nothing more than the power to choose irrationally. In recognition of this problem, some recent libertarians have suggested that free will is paradigmatically manifested only in actions for which we have reasons for both or all the alternatives. In these circumstances, however we choose, we choose rationally. Against this kind of account, most (...) fully developed by Robert Kane, critics have pressed the demand for contrastive explanations. Kane has responded by arguing that the demand does not need to be met: responsibility for an action does not require that there be a contrastive explanation of that action. However, this response proves too much: it implies that agents are responsible not only for the actions they choose, but also for the counterfactual actions which were equally available to them.

Abstract : Libet’s famous experiments, showing that apparently we become aware of our intention to act only after we have unconsciously formed it, have widely been taken to show that there is no such thing as free will. If we are not conscious of the formation of our intentions, many people think, we do not exercise the right kind of control over them. I argue that the claim this view presupposes, that only consciously initiated actions could be free, places a (...) condition upon freedom of action which it is in principle impossible to fulfil, for reasons that are conceptual and not merely contingent. Exercising this kind of control would require that we control our control system, which would simply cause the same problem to arise at a higher-level or initiate an infinite regress of controllings. If the unconscious initiation of actions, as well as the takings of decisions, is incompatible with control over them, then free will is impossible on conceptual grounds. Thus, Libet’s experiments do not constitute a separate, empirical, challenge to our freedom. (shrink)

This introduction traces the philosophical achievements of a thinker sonfluential that his death in 1980 brought 50,000 people on to the streets ofaris. The account of Jean-Paul Sartre - writer, journalist and intellectualornerstone of the 20th century - stretches from his early existential phaseo his later Marxist beliefs. With coverage of such major contemporary issuess human liberty, sociobiology, the ethics of work, and the influence ofenetics on ideas of individual freedom, Neil Levy uses a range of originalaterial not only (...) to introduce Sartre and his work, but also to highlight hisontinuing relevance to today's moral and scientific climate. At the heart ofhis study is a focus on the ethical dimension of Jean-Paul Sartre'shilosophical thought: a focus which challenges us to consider more closelyhe shape of our lives, and the manner in which human beings should treat onenother.

Libertarianism seems vulnerable to a serious problem concerning present luck, because it requires indeterminism somewhere in the causal chain leading to directly free action. Compatibilism, in contrast, is thought to be free of this problem, as not requiring indeterminism in the causal chain. I argue that this view is false: compatibilism is subject to a problem of present luck. This is less of a problem for compatibilism than for libertarianism. However, its effects are just as devastating for one kind of (...) compatibilism, the kind of compatibilism which is history‐sensitive, and therefore must take the problem of constitutive luck seriously. The problem of present luck confronting compatibilism is sufficient to undermine the history‐sensitive compatibilist's response to remote – constitutive – luck. (shrink)

In a series of articles, Terry Horgan and Mark Timmons have argued that Richard Boyd’s defence of moral realism, utilizing a causal theory of reference, fails. Horgan and Timmons construct a twin Earth-style thought experiment which, they claim, generates intuitions inconsistent with the realist account. In their thought experiment, the use of (allegedly) moral terms at a world is causally regulated by some property distinct from that regulating their use here on Earth; nevertheless, Horgan and Timmons claim, it is intuitive (...) that the inhabitants of this world disagree with us in their moral claims. Since any disagreement would be merely verbal were the alleged moral facts identical to or constituted by different natural facts, the identity or constitution claim must be false. I argue that their argument fails. Horgan and Timmons’ thought experiment is underdescribed; when we fill out the details, I claim, we shall see that the challenge to moral realism fades away. I sketch two possible interpretations of the (apparently) moral claims of the inhabitants of moral Twin Earth. On one interpretation, they fail to disagree with us because they actually agree with us; on the other, they fail to disagree with us because they are not moralizers at all. Which interpretation is true, I argue, will depend on the facts that explain the differences between us and the inhabitants of moral twin Earth. (shrink)

We are all apt to alter our beliefs and even our principles to suit the prevailing winds. Examples abound in public life, but we are all subject to similar reversals. We often accuse one another of hypocrisy when these kinds of reversals occur. Sometimes the accusation is justified. In this paper, however, I will argue that in many such cases, we don’t manifest hypocrisy, even if our change of mind is not in response to new evidence. Marshalling evidence from psychology (...) and evolutionary theory, I will suggest that we are designed to update our beliefs in response to social signals: as these signals change, we change our minds, often without even noticing.

Neuroethics is a rapidly growing subfield, straddling applied ethics, moral psychology and philosophy of mind. It has clear affinities to bioethics, inasmuch as both are responses to new developments in science and technology, but its scope is far broader and more ambitious because neuroethics is as much concerned with how the sciences of the mind illuminate traditional philosophical questions as it is with questions concerning the permissibility of using technologies stemming from these sciences. In this article, I sketch the two (...) branches of neuroethics, the applied and the philosophical, and illustrate how they interact. I also consider representative themes from each: the ethics of dampening memory and of cognitive enhancement, on the one hand, and the attack upon the reliability of deontological intuitions and upon free will, on the other.
