This article presents a model for regulating cognitive enhancement devices. Recently, it has become very easy for individuals to purchase devices which directly modulate brain function. For example, transcranial direct current stimulators are increasingly being produced and marketed online as devices for cognitive enhancement. Despite posing risks in a similar way to medical devices, devices that do not make any therapeutic claims do not have to meet anything more than basic product safety standards. We present the case for extending existing medical device legislation to cover CEDs. Medical devices and CEDs operate by the same or similar mechanisms and pose the same or similar risks. This fact coupled with the arbitrariness of the line between treatment and enhancement count in favour of regulating these devices in the same way. In arguing for this regulatory model, the paper highlights potential challenges to its implementation, and suggests solutions.

Recent work in neuroimaging suggests that some patients diagnosed as being in the persistent vegetative state are actually conscious. In this paper, we critically examine this new evidence. We argue that though it remains open to alternative interpretations, it strongly suggests the presence of consciousness in some patients. However, we argue that its ethical significance is less than many people seem to think. There are several different kinds of consciousness, and though all kinds of consciousness have some ethical significance, different kinds underwrite different kinds of moral value. Demonstrating that patients have phenomenal consciousness — conscious states with some kind of qualitative feel to them — shows that they are moral patients, whose welfare must be taken into consideration. But only if they are subjects of a sophisticated kind of access consciousness — where access consciousness entails global availability of information to cognitive systems — are they persons, in the technical sense of the word employed by philosophers. In this sense, being a person is having the full moral status of ordinary human beings. We call for further research which might settle whether patients who manifest signs of consciousness possess the sophisticated kind of access consciousness required for personhood.

Questions concerning free will are intertwined with issues in almost every area of philosophy, from metaphysics to philosophy of mind to moral philosophy, and are also informed by work in different areas of science (principally physics, neuroscience and social psychology). Free will is also a perennial concern of serious thinkers in theology and in non-western traditions. Because free will can be approached from so many different perspectives and has implications for so many debates, a comprehensive survey needs to encompass an enormous range of approaches. This book is the first to draw together leading experts on every aspect of free will, from those who are central to the current philosophical debates, to non-western perspectives, to scientific contributions and to those who know the rich history of the subject. Its 61 chapters, commissioned especially for this volume from the world’s leading researchers, are framed by a General Introduction and briefer introductions for each of the six sections. A list of References, an annotated Suggested Reading list, and a short list of Related Topics are included at the end of each chapter.

Because of the privileged place of beliefs in explaining behaviour, mismatch cases—in which agents sincerely claim to believe that p, but act in a way that is inconsistent with that belief—have attracted a great deal of attention. In this paper, I argue that some of these cases, at least, are at least partially explained by agents believing that they believe that p, while failing to believe that p. Agents in these cases do not believe that ~p; rather, they have an indistinct first‐order, beliefy, representation that p. The indistinctness of this first‐order representation provides the leeway for the inconsistency seen in their behaviour.

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. …

An influential model holds that obsessive–compulsive disorder is caused by distinctive personality traits and belief biases. But a substantial number of sufferers do not manifest these traits. I propose a predictive coding account of the disorder, which explains both the symptoms and the cognitive traits. On this account, OCD centrally involves heightened and dysfunctionally focused attention to normally unattended sensory and motor representations. As these representations have contents that predict catastrophic outcomes, patients are disposed to engage in behaviors and mental rituals designed to forestall these outcomes or to produce more precise information. The same representations also cause the cognitive traits characteristic of sufferers.

Nudges—policy proposals informed by work in behavioural economics and psychology that are designed to lead to better decision-making or better behaviour—are controversial. Critics allege that they bypass our deliberative capacities, thereby undermining autonomy and responsible agency. In this paper, I identify a kind of nudge I call a nudge to reason, which make us more responsive to genuine evidence. I argue that at least some nudges to reason do not bypass our deliberative capacities. Instead, use of these nudges should be seen as appeals to mechanisms partially constitutive of these capacities, and therefore as benign (so far as autonomy and responsible agency are concerned). I sketch some concrete proposals for nudges to reason which are especially important given the apparent widespread resistance to evidence seen in recent political events.

There is good evidence that many people harbour attitudes that conflict with those they endorse. In the language of social psychology, they seem to have implicit attitudes that conflict with their explicit beliefs. There has been a great deal of attention paid to the question whether agents like this are responsible for actions caused by their implicit attitudes, but much less to the question whether they can rightly be described as racist in virtue of harbouring them. In this paper, I attempt to answer this question using three different standards, providing by the three dominant kinds of accounts of racism. I argue that on none of these accounts should agents like this be described as racists. However, it would be misleading to say, without qualification, that they are not racists. On none of these accounts are agents like this entirely off the hook.

There is a robust scientific consensus concerning climate change and evolution. But many people reject these expert views, in favour of beliefs that are strongly at variance with the evidence. It is tempting to try to explain these beliefs by reference to ignorance or irrationality, but those who reject the expert view seem often to be no worse informed or any less rational than the majority of those who accept it. It is also tempting to try to explain these beliefs by reference to epistemic overconfidence. However, this kind of overconfidence is apparently ubiquitous, so by itself it cannot explain the difference between those who accept and those who reject expert views. Instead, I will suggest that the difference is in important part explained by differential patterns of epistemic deference, and these patterns, in turn, are explained by the cues that we use to filter testimony. We rely on cues of benevolence and competence to distinguish reliable from unreliable testifiers, but when debates become deeply politicized, asserting a claim may itself constitute signalling lack of reliability.

Cases in which we find ourselves irrationally worried about whether we have done something we habitually do are familiar to most people, but they have received surprisingly little attention in the philosophical literature. In this paper, I argue that available accounts designed to explain superficially similar mismatches between agents’ behavior and their beliefs fail to explain these cases. In the kinds of cases which have served as paradigms for extant accounts, contents are poised to drive behavior in a belief-like way. But the contents of these irrational worries are not poised in a belief-like way. Nor do they cause behavior due to a deficit of rational scrutiny. Rather, these representations cause behavior deviantly: by generating anxiety, which in turn motivates actions aimed at assuaging it

ABSTRACT: In his last two books and in the essays and interviews associated with them, Foucault develops a new mode of ethical thought he describes as an aesthetics of existence. I argue that this new ethics bears a striking resemblance to the virtue ethics that has become prominent in Anglo‐American moral philosophy over the past three decades, in its classical sources, in its opposition to rule‐based systems and its positive emphasis upon what Foucault called the care for the self. I suggest that seeing Foucault and virtue ethicists as engaged in a convergent project sheds light on a number of obscurities in Foucault’s thought, and provides us with a historical narrative in which to situate his claims about the development of Western moral thought.

The question whether and when it is morally appropriate to withdraw life-support from patients diagnosed as being in the persistent vegetative state is one of the most controversial in bioethics. Recent work on the neuroscience of consciousness seems to promise fundamentally to alter the debate, by demonstrating that some entirely unresponsive patients are in fact conscious. In this paper, I argue that though this work is extremely important scientifically, it ought to alter the debate over the moral status of the patients very little. First, the data presented is complex and difficult to interpret; we should be wary of taking the claimed discovery entirely at face value (though the remaining questions will probably be settled by future research). Second, though the demonstration that some of the patients are in fact conscious would show that they are moral patients, and therefore beings whose welfare must be taken into account, it would not, by itself at any rate, show that they have an interest in continued life.

One of the major conflicts in the social sciences since the Second World War has concerned whether, and to what extent, human beings have a nature. One view, traditionally associated with the political left, has rejected the notion that we have a contentful nature, and hoped thereby to underwrite the possibility that we can shape social institutions by references only to norms of justice, rather than our innate dispositions. This view has been in rapid retreat over the past three decades, in the face of an onslaught from several different strands of psychology purporting to show that human nature has a content. In this paper, I argue for a third view: that human beings have a contentful nature, but that nature is uniquely flexible and therefore places relatively few constraints on the shape of our social institutions. Human beings are shaped, by nature, to be cultural animals. We are innately disposed to imitate the behavior of those around us, to a far greater degree than other animals: this disposition toward overimitation allows us to construct local traditions of behavior and thereby to adapt to an enormous variety of environments. These facts, in turn, ensure that human populations live embedded in local forms of life; thus our nature entails that we are deeply cultural animals
