ABSTRACT Should surgeons be permitted to amputate healthy limbs if patients request such operations? We argue that if such patients are experiencing significant distress as a consequence of the rare psychological disorder named Body Integrity Identity Disorder (BIID), such operations might be permissible. We examine rival accounts of the origins of the desire for healthy limb amputations and argue that none are as plausible as the BIID hypothesis. We then turn to the moral arguments against such operations, and argue that (...) on the evidence available, none is compelling. BIID sufferers meet reasonable standards for rationality and autonomy: so as long as no other effective treatment for their disorder is available, surgeons ought to be allowed to accede to their requests.

In 1997, a Scottish surgeon by the name of Robert Smith was approached by a man with an unusual request: he wanted his apparently healthy lower left leg amputated. Although details about the case are sketchy, the would-be amputee appears to have desired the amputation on the grounds that his left foot wasn’t part of him – it felt alien. After consultation with psychiatrists, Smith performed the amputation. Two and a half years later, the patient reported that his life had (...) been transformed for the better by the operation [1]. A second patient was also reported as having been satisfied with his amputation [2]. (shrink)

Actions performed in a state of automatism are not subject to moral evaluation, while automatic actions often are. Is the asymmetry between automatistic and automatic agency justified? In order to answer this question we need a model or moral accountability that does justice to our intuitions about a range of modes of agency, both pathological and non-pathological. Our aim in this paper is to lay the foundations for such an account.

Disorders of volition are often accompanied by, and may even be caused by, disruptions in the phenomenology of agency. Yet the phenomenology of agency is at present little explored. In this paper we attempt to describe the experience of normal agency, in order to uncover its representational content.

Is it generally rational to defer to official stories? On the affirmative view exemplified by Neil Levy, grounds for scepticism cannot outweigh the epistemic authority of the experts presumed to generate them. Yet sociological studies of how expertise is mediated into official communications reveal the epistemic potential of citizens’ collaboratives. These may include, or advocate hearing, dissident experts. Such groups’ epistemic position is arguably analogous to that of the ‘other institutions of civil society’ that Levy sees as (...) underwriting the authority of official stories. An added advantage is that they are able to adhere to deliberative methods of inquiry. By contrast, an official story presupposes that deliberations have concluded, and what remains is to promote the agreed story. This is achieved by strategic communication, which can involve extensive coordination by organisations committed primarily to persuasion rather than truth-seeking. Sometimes it includes blocking dissidents’ deliberative challenges. A case study highlights how even an organisation of indisputable epistemic authority can be politically influenced to block the testimony of its own scientific experts, while uncritical support for its official story is maintained by other institutions of civil society. Hence, an appropriate attitude towards official stories is critical receptiveness rather than automatic deference. (shrink)

In this paper we defend the doxastic conception of delusions against the metacognitive account developed by Greg Currie and collaborators. According to the metacognitive model, delusions are imaginings that are misidentified by their subjects as beliefs: the Capgras patient, for instance, does not believe that his wife has been replaced by a robot, instead, he merely imagines that she has, and mistakes this imagining for a belief. We argue that the metacognitive account is untenable, and that the traditional conception of (...) delusions as beliefs should be retained. (shrink)

Tacit knowledge is the form of implicit knowledge that we rely on for learning. It is invoked in a wide range of intellectual inquiries, from traditional academic subjects to more pragmatically orientated investigations into the nature and transmission of skills and expertise. Notwithstanding its apparent pervasiveness, the notion of tacit knowledge is a complex and puzzling one. What is its status as knowledge? What is its relation to explicit knowledge? What does it mean to say that knowledge is tacit? Can (...) it be measured? Recent years have seen a growing interest from philosophers in understanding the nature of tacit knowledge. Philosophers of science have discussed its role in scientific problem-solving; philosophers of language have been concerned with the speaker's relation to grammatical theories; and phenomenologists have attempted to describe the relation of explicit theoretical knowledge to a background understanding of matters that are taken for granted. This book seeks to bring a unity to these diverse philosophical discussions by clarifying their conceptual underpinnings. In addition the book advances a specific account of tacit knowledge that elucidates the importance of the concept for understanding the character of human cognition, and demonstrates the relevance of the recommended account to those concerned with the communication of expertise. The book will be of interest to philosophers of language, epistemologists, cognitive psychologists and students of theoretical linguistics. (shrink)

Howard Robinson has argued that even if the major claims of Berkeleian idealism are mistaken, including its account of the “physical world,” “the overall endeavour of defending idealism is more plausible than it is generally believed to be”. He argues that aspects of Berkeley’s arguments for idealism, including a Berkeleian argument against naive realism, can be shown to refute the representative realist’s view of perception, and its concomitant ontology. This ontology is at least partially materialist. According to Robinson, once naive (...) realism is disposed of and the objections to RR are exposed, Berkeleian Idealism can raise its shadowy head with at least the respectability afforded the currently more fashionable Representationalism. We shall argue that Robinson’s claim cannot plausibly be sustained. His defense of Berkeleian idealism, based in part on his understanding of naive realism and his critique of Representationalism, falters. “The overall endeavour of defending idealism” is not as plausible as Robinson takes it to be.

We argue against the halving response to Sleeping Beauty. First, we outline an appealing constraint on probability assignments: the Principle of Irrelevant Information. Roughly, this says: if you don’t know whether C, but you would assign probability r to A regardless of whether C or not-C, then you should assign r to A. This Principle is deeply plausible, but we show that it contradicts halving. Second, we show that halving violates solid statistical reasoning.

Tim Bayne draws on philosophy, psychology, and neuroscience in defence of the claim that consciousness is unified. He develops an account of what it means to say that consciousness is unified, and then applies this account to a variety of cases - drawn from both normal and pathological forms of experience - in which the unity of consciousness is said to break down. He goes on to explore the implications of the unity of consciousness for theories of consciousness, for (...) the sense of embodiment, and for accounts of the self. The Unity of Consciousness draws on a wide range of findings within philosophy and the sciences of the mind to construct an account of the unity of consciousness that is both conceptually sophisticated and scientifically informed.

Does thought have distinctive experiential features? Is there, in addition to sensory phenomenology, a kind of cognitive phenomenology--phenomenology of a cognitive or conceptual character? Leading philosophers of mind debate whether conscious thought has cognitive phenomenology and whether it is part of conscious perception and conscious emotion.

At any given time, a subject has a multiplicity of conscious experiences. A subject might simultaneously have visual experiences of a red book and a green tree, auditory experiences of birds singing, bodily sensations of a faint hunger and a sharp pain in the shoulder, the emotional experience of a certain melancholy, while having a stream of conscious thoughts about the nature of reality. These experiences are distinct from each other: a subject could experience the red book without the singing (...) birds, and could experience the singing birds without the red book. But at the same time, the experiences seem to be tied together in a deep way. They seem to be unified, by being aspects of a single encompassing state of consciousness. (shrink)

So‐called downshifters seek more meaningful lives by decreasing the amount of time they devote to work, leaving more time for the valuable goods of friendship, family and personal development. But though these are indeed meaning‐conferring activities, they do not have the right structure to count as superlatively meaningful. Only in work – of a certain kind – can superlative meaning be found. It is by active engagements in projects, which are activities of the right structure, dedicated to the achievement of (...) goods beyond ourselves, that we make our lives superlatively meaningful.

Whatever its implications for the other features of human agency at its best — for moral responsibility, reasons-responsiveness, self-realization, flourishing, and so on—addiction is universally recognized as impairing autonomy. But philosophers have frequently misunderstood the nature of addiction, and therefore have not adequately explained the manner in which it impairs autonomy. Once we recognize that addiction is not incompatible with choice or volition, it becomes clear that none of the Standard accounts of autonomy can satisfactorily explain the way in which (...) it undermines fully autonomous agency. In order to understand to what extent and in what ways the addicted are autonomy-impaired, we need to understand autonomy as consisting, essentially, in the exercise of the capacity forextended agency.It is because addiction undermines extended agency, so that addicts are not able to integrate their lives and pursue a Single conception of the good, that it impairs autonomy.

The phenomenal character of perceptual experience involves the representation of colour, shape and motion. Does it also involve the representation of high-level categories? Is the recognition of a tomato as a tomato contained within perceptual phenomenality? Proponents of a conservative view of the reach of phenomenal content say ’No’, whereas those who take a liberal view of perceptual phenomenality say ’Yes’. I clarify the debate between conservatives and liberals, and argue in favour of the liberal view that high-level content can (...) directly inform the phenomenal character of perception. (shrink)

We are constantly called upon to evaluate the evidential weight of testimony, and to balance its deliverances against our own independent thinking. ‘Intellectual autonomy’ is the virtue that is supposed to be displayed by those who engage in cognition in this domain well. I argue that this is at best a misleading label for the virtue, because virtuous cognition in this domain consists in thinking with others, and intelligently responding to testimony. I argue that the existing label supports an excessively (...) individualistic conception of good thinking, both within and outside philosophy. I propose replacing ‘intellectual autonomy’ with ‘intellectual interdependence’, which properly emphasises the depth of our reliance on one another, without suggesting we ought ever to be epistemically servile.

ABSTRACT Many people now believe that human reproductive cloning – once sufficiently safe and effective – should be permitted on the grounds that it will allow the otherwise infertile to have children that are biologically closely related to them. However, though it is widely believed that the possession of a close genetic link to our children is morally significant and valuable, we argue that such a view is erroneous. Moreover, the claim that the genetic link is valuable is pernicious; it (...) tends to give rise to highly undesirable consequences, and therefore should be combated rather than pandered to. The emphasis on the genetic is unwarranted and unfortunate; rather than giving us moral reason to support reproductive cloning in the case of infertility, the fact that cloning requests are likely to be motivated by the genetic argument gives us reason to oppose its availability.

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.

The phenomenology of agency has, until recently, been rather neglected, overlooked by both philosophers of action and philosophers of consciousness alike. Thankfully, all that has changed, and of late there has been an explosion of interest in what it is like to be an agent. 1 This burgeoning field crosses the traditional boundaries between disciplines: philosophers of psychopathology are speculating about the role that unusual experiences of agency might play in accounting for disorders of thought and action; cognitive scientists are (...) developing models of how the phenomenology of agency is generated; and philosophers of mind are drawing connections between the phenomenology of agency and the nature of introspection, phenomenal character, and agency itself. My aim in this paper is not to provide an exhaustive survey of this recent literature, but to provide a.. (shrink)

Where in cognitive architecture do experiences of agency lie? This chapter defends the claim that such states qualify as a species of perception. Reference to ‘the sense of agency’ should not be taken as a mere façon de parler but picks out a genuinely perceptual system. The chapter begins by outlining the perceptual model of agentive experience before turning to its two main rivals: the doxastic model, according to which agentive experience is really a species of belief, and the telic (...) model, according to which agentive experience is really a species of agency.

One of the central problems in the study of consciousness concerns the ascription of consciousness. We want to know whether certain kinds of creatures—such as non-human animals, artificially created organisms, and even members of our own species who have suffered severe brain-damage—are conscious, and we want to know what kinds of conscious states these creatures might be in if indeed they are conscious. The identification of accurate markers of consciousness is essential if the science of consciousness is to have any (...) chance of success. (shrink)

Is consciousness multisensory? Obviously it is multisensory in certain ways. Human beings typically possess the capacity to have experiences in at least the five familiar sensory modalities, and quite possibly in a number of other less commonly recognised modalities as well. But there are other respects in which it is far from obvious that consciousness is multisensory. This chapter is concerned with one such respect. Οur concern here is with whether consciousness contains experiences associated with distinct modalities at the same (...) time. We will describe those who endorse a positive answer to this question as endorsing a multisensory view (MSV) of the structure of consciousness, and those who endorse a negative answer to this question as having a unisensory view (USV) of the structure of consciousness.

According to conventional wisdom, the split-brain syndrome puts paid to the thesis that consciousness is necessarily unified. The aim of this paper is to challenge that view. I argue both that disunity models of the split-brain are highly problematic, and that there is much to recommend a model of the split-brain—the switch model—according to which split-brain patients retain a fully unified consciousness at all times. Although the task of examining the unity of consciousness through the lens of the split-brain syndrome (...) is not a new one—such projects date back to Nagel’s seminal paper on the topic—the time is ripe for a re-evaluation of the issues.

Viewed from a certain perspective, nothing can seem more secure than introspection. Consider an ordinary conscious episode—say, your current visual experience of the colour of this page. You can judge, when reflecting on this experience, that you have a visual experience as of something white with black marks before you. Does it seem reasonable to doubt this introspective judgement? Surely not—such doubt would seem utterly fanciful. The trustworthiness of introspection is not only assumed by commonsense, it is also taken for (...) granted by many of theorists about the mind. Within both philosophy and the science of consciousness it is widely held that introspection is generally reliable, at least with respect to the question of one’s current (or immediately prior) conscious states. Without this assumption, we could not make sense of theorists’ widespread use of introspection, both in support of their own position and to undermine that of their opponents. (shrink)

After being sorely neglected for some time, consciousness is well and truly back on the philosophical and scientific agenda. This entry provides a whistle-stop tour of some recent debates surrounding consciousness, with a particular focus on issues relevant to the scientific study of consciousness.

A popular approach to monothematic delusions in the recent literature has been to argue that monothematic delusions involve broadly rational responses to highly unusual experiences. Campbell calls this the empiricist approach to monothematic delusions, and argues that it cannot account for the links between meaning and rationality. In place of empiricism Campbell offers a rationalist account of monothematic delusions, according to which delusional beliefs are understood as Wittgensteinian framework propositions. We argue that neither Campbell's attack on empiricism nor his rationalist (...) alternative to empiricism is successful. (shrink)

In the past two decades, epistemologists have significantly expanded the focus of their field. To the traditional question that has dominated the debate — under what conditions does belief amount to knowledge? — they have added questions about testimony, epistemic virtues and vices, epistemic trust, and more. This broadening of the range of epistemic concern has coincided with an expansion in conceptions of epistemic agency beyond the individualism characteristic of most earlier epistemology. We believe that these developments have not gone (...) far enough. While the weak anti-individualism we see in contemporary epistemology may be adequate for the kinds of cases it tends to focus on, a great deal of human knowledge production and transmission does not conform to these models. Furthermore, the dispositions and norms that are knowledge-conducive in the familiar cases may not be knowledge-conducive generally. In fact, dispositions that, at an individual level, count as epistemic vices may be epistemic virtues in common social contexts. We argue that this overlooked feature of human social life means that epistemology must become more deeply and pervasively social. (shrink)

The papers in this volume are drawn from a workshop on delusion and self-deception, held at Macquarie University in November of 2004. Our aim was to bring together theorists working on delusions and self-deception with an eye towards identifying and fostering connections—at both empirical and conceptual levels—between these domains. As the contributions to this volume testify, there are multiple points of contact between delusion and self-deception. This introduction charts the conceptual space in which these points of contact can be located (...) and introduces the reader to some of the general issues that frame the discussion of subsequent chapters.

Explanation does not exist in a metaphysical vacuum. Conceptions of the structure of a phenomenon play an important role in guiding attempts to explain it, and erroneous conceptions of a phenomenon may direct investigation in misleading directions. I believe that there is a case to be made for thinking that much work on the neural underpinnings of consciousness—what is often called the neural correlates of consciousness—is driven by an erroneous conception of the structure of consciousness. The aim of this paper (...) is lay bare some connections between the explanation of consciousness and the structure of consciousness, and to argue for a conception of the structure of consciousness that is more adequate than that which currently drives much research into the neural correlates of consciousness.

Given its ubiquitous presence in everyday experience, it is surprising that the phenomenology of doing—the experience of being an agent—has received such scant attention in the consciousness literature. But things are starting to change, and a small but growing literature on the content and causes of the phenomenology of first-person agency is beginning to emerge.2 One of the most influential and stimulating figures in this literature is Daniel Wegner. In a series of papers and his book The Illusion of Conscious (...) Will (ICW) Wegner has developed.. (shrink)

Hypnosis appears to generate unusual—and sometimes even astonishing—changes in the contents of consciousness. Hypnotic subjects report perceiving things that are not there, they report not perceiving things that are there, and they report unusual alterations in the phenomenology of agency. In addition to apparent alterations in the contents of consciousness, hypnosis also appears to involve alterations in the structure of consciousness. According to many theorists—most notably Hilgard—hypnosis demonstrates that the unity of consciousness is an illusion (Hilgard 1977).

The accusation of virtue signalling is typically understood as a serious charge. Those accused usually respond by attempting to show that they are doing no such thing. In this paper, I argue that we ought to embrace the charge, rather than angrily reject it. I argue that this response can draw support from cognitive science, on the one hand, and from social epistemology on the other. I claim that we may appropriately concede that what we are doing is virtue signalling, (...) because virtue signalling is morally appropriate. It neither expresses vices, nor is hypocritical, nor does it degrade the quality of public moral discourse. Signalling our commitment to norms is a central and justifiable function of moral discourse, and the same signals provide evidence that is appropriately taken into account in forming moral beliefs.

We have various everyday measures for identifying the presence of consciousness, such as the capacity for verbal report and the intentional control of behavior. However, there are many contexts in which these measures are difficult to apply, and even when they can be applied one might have doubts as to their validity in determining the presence/absence of consciousness. Everyday measures for identifying consciousness are particularly problematic when it comes to ‘challenging cases’—human infants, people with brain damage, nonhuman animals, and AI (...) systems. There is a pressing need to identify measures of consciousness that can be applied to challenging cases. This paper explores one of the most promising strategies for identifying and validating such measures—the natural-kind strategy. The paper is in two broad parts. Part I introduces the natural-kind strategy, and contrasts it with other influential approaches in the field. Part II considers a number of objections to the approach, arguing that none succeeds.

The on-going debate over the ‘admissible contents of perceptual experience’ concerns the range of properties that human beings are directly acquainted with in perceptual experience. Regarding vision, it is relatively uncontroversial that the following properties can figure in the contents of visual experience: colour, shape, illumination, spatial relations, motion, and texture. The controversy begins when we ask whether any properties besides these figure in visual experience. We argue that ‘ensemble properties’ should be added to the list of visually admissible properties. (...) Ensemble properties are features that belong to a set of perceptible objects as a whole as opposed to the individuals that constitute that set. They include such features as the mean size of an array of shapes or the average emotional expression of an array of faces. Recent work in vision science has yielded compelling evidence that the visual system routinely encodes such properties. We argue that epistemological considerations provide strong reasons to think that these properties figure in visual experience. Judgements about ensemble properties are immediately warranted by our perceptual experience, and the only plausible way that a perceptual experience could confer this warrant is if it confers awareness of ensemble properties.

What exactly is it that makes someone a parent? Many people hold that parenthood is grounded, in the first instance, in the natural derivation of one person's genetic constitution from the genetic constitutions of others. We refer to this view as "Geneticism". In Part I we distinguish three forms of geneticism on the basis of whether they hold that direct genetic derivation is sufficient, necessary, or both sufficient and necessary, for parenthood. Parts two through four examine three arguments for geneticism: (...) the property argument, the causal argument, and the parity argument. We conclude that none of these arguments succeeds. (shrink)

In his 1996 paper Neurophenomenology: A methodological remedy for the hard problem, Francisco Varela called for a union of Husserlian phenomenology and cognitive science. Varela''s call hasn''t gone unanswered, and recent years have seen the development of a small but growing literature intent on exploring the interface between phenomenology and cognitive science. But despite these developments, there is still some obscurity about what exactly neurophenomenology is. What are neurophenomenologists trying to do, and how are they trying to do it? To (...) what extent is neurophenomenology a distinctive and unified research programme? In this paper I attempt to shed some light on these questions. (shrink)

Although delusions are typically regarded as beliefs of a certain kind, there have been worries about the doxastic conception of delusions since at least Bleuler’s time. ‘Anti-doxasticists,’ as we might call them, do not merely worry about the claim that delusions are beliefs, they reject it. Reimer’s paper weighs into the debate between ‘doxasticists’ and ‘anti-doxasticists’ by suggesting that one of the main arguments given against the doxastic conception of delusions—what we might call the functional role objection—is based on a (...) fallacy.

Free will sceptics claim that we do not possess free will—or at least, that we do not possess nearly as much free will as we think we do. Some free will sceptics hold that the very notion of free will is incoherent, and that no being could possibly possess free will (Strawson this volume). Others allow that the notion of free will is coherent, but hold that features of our cognitive architecture prevent us from possessing free will. My concern in (...) this chapter is with views of the second kind. According to an increasingly influential line of thought, our common-sense commitment to the existence of free will is threatened in unique ways by what we are learning from the sciences of human agency.

A central debate in the philosophy of perception concerns the range of properties that can be represented in perceptual experience. Are the contents of perceptual experience restricted to ‘low-level’ properties such as location, shape and texture, or can ‘high-level’ properties such as being a tomato, being a pine tree or being a watch also be represented in perceptual experience? This paper explores the bearing of gist perception on the admissible contents debate, arguing that it provides qualified support for the claim (...) that certain kinds of high-level properties—such as being a natural scene —can be perceptually represented.

The question of the psychopath's responsibility for his or her wrongdoing has received considerable attention. Much of this attention has been directed toward whether psychopaths are a counterexample to motivational internalism (MI): Do they possess normal moral beliefs, which fail to motivate them? In this paper, I argue that this is a question that remains conceptually and empirically intractable, and that we ought to settle the psychopath's responsibility in some other way. I argue that recent empirical work on the moral (...) judgments of psychopaths provides us with good reason to think that they are not fully responsible agents, because their actions cannot express the kinds of ill-will toward others that grounds attributions of distinctively moral responsibility. I defend this view against objections, especially those due to an influential account of moral responsibility that holds that moral knowledge is not necessary for responsibility. (shrink)
