Behrendt & Young's (B&Y's) novel “unifying model” of hallucinations, although comprehensive, fails to incorporate research into the possible role of 5-HT2A receptors in the mode of action of novel “atypical” antipsychotic drugs (which treat hallucinations effectively), and into the role of such receptors, which are located in thalamocortical circuits, in mediating drug-induced hallucinations.
In this paper I argue in favour of a new deﬁnition of presentism that I call ‘existence presentism’ (EP). Typically, presentism is deﬁned as the thesis that ‘only present objects exist’, or ‘nothing exists that is non-present’.1 I assume these statements to be equivalent. I call these statements of presentism ‘conventional presentism’ (CP). First, in §2, I rehearse arguments due to Ulrich Meyer that purport to show that presentism is not adequately deﬁned as CP. In §§2.1–2.4 I show that considerations (...) of the sort raised by Meyer infect attempts to deﬁne presentism, due to Thomas Crisp, Tom Stoneham, and Theodore Sider. Thus the ﬁrst half of the paper is constituted by a negative project that looks to show how extant deﬁnitions of presentism fail. In the second half of the paper, I continue in the negative theme in §3, before laying out EP and demonstrating that it solves the problems faced by CP and offering explanations of how to make sense of certain key notions that lie at the heart of EP. I conclude that EP is preferable to CP. (shrink)
The law tends to think that there is no difficulty about identifying humans. When someone is born, her name is entered into a statutory register. She is ‘X’ in the eyes of the law. At some point, ‘X’ will die and her name will be recorded in another register. If anyone suggested that the second X was not the same as the first, the suggestion would be met with bewilderment. During X's lifetime, the civil law assumed that the X who (...) entered into a contract was the same person who breached it. The criminal law assumed that X, at the age of 80, was liable for criminal offences ‘she’ committed at the age of 18. This accords with the way we talk. ‘She's not herself today’, we say; or ‘When he killed his wife he wasn't in his right mind’. The intuition has high authority: ‘To thine own self be true’, urged Polonius.1 It sounds as if we believe in souls—immutable, core essences that constitute our real selves. Medicine conspires in the belief. If you become mentally ill, a psychiatrist will seek to get you back to your right mind. The Mental Capacity Act 1985 states that when a patient loses capacity the only lawful interventions will be interventions which are in that patient's best interests,2 and that in determining what those interests are the decision-maker must have ….

In a majority of situations the normal adult maintains posture or moves without consciously monitoring motor activity. Posture and movement are usually close to automatic; they tend to take care of themselves, outside of attentive regard. One's body, in such cases, effaces itself as one is geared into a particular intentional goal. This effacement is possible because of the normal functioning of a body schema. Body schema can be defined as a system of preconscious, subpersonal processes that play a dynamic (...) role in governing posture and movement (Head, 1920). There is an important and often overlooked conceptual difference between the subpersonal body schema and what is usually called body image . The latter is most often defined as a conscious idea or mental representation that one has of one's own body (for example, Adame, Radell, Johnson, and Cole, 1991; Gardner and Moncrieff, 1988; Schilder, 1935). Despite the conceptual difference many researchers use the terms interchangeably, leading to both a terminological and conceptual confusion. (shrink)
Subjects estimated the time of intentions to perform an action, of the action itself, or of an auditory effect of the action. A perceptual attraction or binding effect occurred between actions and the effects that followed them. Judgements of intentions did not show this binding, suggesting they are represented independently of actions and their effects. In additional unpredictable judgement conditions, subjects were instructed only after each trial which of these events to judge, thus discouraging focussed attention to a specific event. (...) Stronger binding effects were found, with intention, action and effect fusing to a single central point in time. In a control task, subjects reported the time of the first or second tone in sequence. Tone sequences showed no binding at all when subjects knew in advance which tone to judge, but showed the same fusion as actions when the event to be judged was not predictable. Binding of actions and effects, but not of tone sequences, occurs pre-attentively, and automatically. The data are consistent with a reconstructive process, implemented after actions, which generates a coherent sense of agency. However, this process should only be triggered only when our actions make it appropriate. We suggest that this mechanism is triggered in advance by efferent processing. This conclusion was supported by a further study in deafferented subject IW. This subject showed the normal binding of a tone towards an action, although his experience of the action was of pre-motor, rather than peripheral origin. The experience of intentional action involves an interplay between pre-motor and reconstructive processes. (shrink)
We are defined by our faces. They give identity but, equally importantly, reveal our moods and emotions through facial expression. So what happens when the face cannot move? This book is about people who live with Mbius Syndrome, which has as its main feature an absence of movement of the muscles of facial expression from birth.

Empirical studies of gesture in a subject who has lost proprioception and the sense of touch from the neck down show that specific aspects of gesture remain normal despite abnormal motor processes for instrumental movement. The experiments suggest that gesture, as a linguistic phenomenon, is not reducible to instrumental movement. They also support and extend claims made by Merleau-Ponty concerning the relationship between language and cognition. Gesture, as language, contributes to the accomplishment of thought.
Proprioception has been considered, within neuroscience, in the context of the control of movement. Here we discuss a possible second role for this ‘sixth sense’, pleasure in and of movement, homologous with the recently described affective touch. We speculate on its evolution and place in human society and suggest that pleasure in movement may depend not on feedback but also on harmony between intention and action. Examples come from expert movers, dancers and sportsmen, and from those without proprioception due to (...) neurological impairment. Finally we suggest that affective proprioception may help bind our sense of agency with our embodied selves at an emotional level. (shrink)
This paper considers the importance of the body for self-esteem, communication, and emotional expression and experience, through the reflections of those who live with various neurological impairments of movement and sensation; sensory deafferentation, spinal cord injury and Möbius Syndrome. People with severe sensory loss, who require conscious attention and visual feedback for movement, describe the imperative to use the same strategies to reacquire gesture, to appear normal and have embodied expression. Those paralysed after spinal cord injury struggle to have others (...) see them as people rather than as people in wheelchairs and have been active in the disability movement, distinguishing between their medical impairment and the social induced disability others project onto them. Lastly those with Möbius reveal the importance of the face for emotional expression and communication and indeed for emotional experience itself. All these examples explore the crucial role of the body as agent for social and personal expression and self-esteem. (shrink)
For most people a sense of self includes an embodied component: when describing our selves we describe those aspects of our physical bodies which can be easily codified: height, hair colour, sex, eye colour. Even when we consider ourselves we tend not to consider our intellectual cognitive characteristics but our describable anatomy. Wittgenstein's dictum, ‘the human body is the best picture of the human soul’, is relevant here but I would like to go further: the body-part we feel most embodied (...) in is our face, even though it is difficult to describe and so forms little part of how we describe ourselves to others.

We are very grateful to Richard Ashcroft1 and Andrew McGee2 for their thoughtful and articulate criticisms of our views.3 Ashcroft has disappointingly low aspirations for the law. Of course he is right to say that the law is not a ‘self-sufficient, integrated and self-interpreting system of doctrine’. The law is often philosophically incoherent and internally contradictory. But it does not follow from this that all areas of the law are philosophically unsatisfactory. And if that were true, the response should not (...) be Ashcroft’s contemptuous despair, but a determination to make it better. Ashcroft would say that such idealism is unrealistic in the light of the very nature of ‘the Law’: ‘…a complex assemblage of institutions, rules, accredited persons, practices and systems’. That isa radically ‘legal realist’ position and is plainly unsustainable. We can demonstrate its unsustainability while demonstrating both that he is wrong to tar all areas of the law with the same brush and wrong to deny that medical ethics are ‘intellectually and metaphysically prior to medical law’. Take the law of murder which, of course, is part of ‘medical law’. It is surely trite to observe that humans thought that killing people was wrong before they started penalising murder. Ethics generated the law. There is nothing elusive or incoherent about the philosophical foundations of the law of murder. Human life is thought to matter. To kill is both to cause a harm and to commit a wrong. There is more than something of the straw man in Ashcroft’s elaboration of his argument. For he chooses, of all things, autonomy and, in particular, its invocation in the law of consent. Lawyers’ eyebrows will rise at his assertion that ‘while the concept of “autonomy” has an explanatory role in discussions of the …. (shrink)
The “doctrine of double effect” has a pleasing ring to it. It is regarded by some as the cornerstone of any sound approach to end-of-life issues and by others as religious mumbo jumbo. Discussions about “the doctrine” often generate more heat than light. They are often conducted at cross-purposes and laced with footnotes from Leviticus.
Did protolanguage users use discrete words that referred to objects, actions, locations, etc., and then, at some point, combine them; or on the contrary did they have words that globally indexed whole semantic complexes, and then come to divide them? Our answer is: early humans were forming language units consisting of global and discrete dimensions of semiosis in dynamic opposition. These units of thinking-for-speaking, or ‘growth points’ (GPs) were, jointly, analog imagery (visuo-spatio-motoric) and categorically-contrastive (-emic) linguistic encodings. This discrete-global duality (...) was a new mode of embodied cognition that enabled thinking and acting in new ways: the dawn of protolanguage. Where did this mode of cognition come from? We have some suggestions based on the hypothesis that gestures gained the power to orchestrate actions, manual and vocal, with significances other than those of the actions themselves, giving rise to cognition framed in the proposed dual terms. Note, however, our proposal is not one of the ‘gesture-first’ theories of language origins. Such theories predict what did not evolve: a language of pantomime; rather than what did evolve: an integrated system of synchronized gestures and spoken forms. GP theory is an account of the cognition underlying such an integrated system. A scenario for the evolutionary selection of this cognitive mode is ‘Mead’s Loop’, a model in which one’s cognition is enriched by one’s own gestures, insofar as they are objects in social interactions.

We review different analytic approaches to narratives by those with psychopathological conditions, and we suggest that the interpretation of such narratives are complicated by a variety of phenomenological and hermeneutical considerations. We summarize an empirical study of narrative distance in narratives by non-pathological subjects, and discuss how the results can be interpreted in two different ways with regard to the issue of dissociation.
The importance of the face is best understood, it is suggested, from the effects of visible facial difference in people. Their experience reflects the ways in which the face may be necessary for the interpersonal relatedness underlying such 'sharing' mind states as empathy. It is proposed that the face evolved as a result of several evolutionary pressures but that it is well placed to assume the role of an embodied representation of the increasingly refined inner states of mind that developed (...) as primates became more social, and required more complex social intelligence. -/- The consequences of various forms of facial disfigurement on interpersonal relatedness and intersubjectivity are then discussed. These narratives reveal the importance of the face in the development of the self-esteem that seems a prerequisite of being able to initiate, and enter, relationships between people. Such experiences are beyond normal experience and, as such, require an extended understanding of the other: to understand facial difference requires empathy. But, in addition, it is also suggested that empathy itself is supported by, and requires, the embodied expression and communication of emotion that the face provides. (shrink)
Three experiments with 88 college-aged participants explored how unlabeled experiences—learning episodes in which people encounter objects without information about their category membership—influence beliefs about category structure. Participants performed a simple one-dimensional categorization task in a brief supervised learning phase, then made a large number of unsupervised categorization decisions about new items. In all three experiments, the unsupervised experience altered participants’ implicit and explicit mental category boundaries, their explicit beliefs about the most representative members of each category, and even their memory (...) for the items encountered during the supervised learning phase. These changes were influenced by both the range and frequency distribution of the unlabeled stimuli: mental category boundaries shifted toward the middle of the range and toward the trough of the bimodal distribution of unlabeled items, whereas beliefs about the most representative category members shifted toward the modes of the unlabeled distribution. One consequence of this shift in representations is a false-consensus effect (Experiment 3) where participants, despite receiving very disparate training experiences, show strong agreement in judgments about representativeness and boundary location following unsupervised category judgments.

In these seventeen essays, distinguished senior scholars discuss the conceptual issues surrounding the idea of freedom of inquiry and scrutinize a variety of obstacles to such inquiry that they have encountered in their personal and professional experience. Their discussion of threats to freedom traverses a wide disciplinary and institutional, political and economic range covering specific restrictions linked to speech codes, the interests of donors, institutional review board licensing, political pressure groups, and government policy, as well as phenomena of high generality, (...) such as intellectual orthodoxy, in which coercion is barely visible and often self-imposed. As the editors say in their introduction: "No freedom can be taken for granted, even in the most well-functioning of formal democracies. Exposing the tendencies that undermine freedom of inquiry and their hidden sources and widespread implications is in itself an exercise in and for democracy.". (shrink)
The notion of an enactive system requires thinking about the brain in a way that is different from the standard computational-representational models. In evolutionary terms, the brain does what it does and is the way that it is, across some scale of variations, because it is part of a living body with hands that can reach and grasp in certain limited ways, eyes structured to focus, an autonomic system, an upright posture, etc. coping with specific kinds of environments, and with (...) other people. Changes to any of the bodily, environmental, or intersubjective conditions elicit responses from the system as a whole. On this view, rather than representing or computing information, the brain is better conceived as participating in the action. (shrink)
Although Arbib's extension of the mirror-system hypothesis neatly sidesteps one problem with the “gesture-first” theory of language origins, it overlooks the importance of gestures that occur in current-day human linguistic performance, and this lands it with another problem. We argue that, instead of gesture-first, a system of combined vocalization and gestures would have been a more natural evolutionary unit.
Studies of perception have focussed on sensation, though more recently the perception of action has, once more, become the subject of investigation. These studies have looked at acute experimental situations. The present paper discusses the subjective experience of those with either clinical syndromes of loss of movement or sensation (spinal cord injury, sensory neuronopathy syndrome or motor stroke), or with experimental paralysis or sensory loss. The differing phenomenology of these is explored and their effects on intention and agency discussed. It (...) is shown that sensory loss can have effects on the focussing of motor command and that for some a sense of agency can return despite paralysis. (shrink)
I show that given Jonathan Bennett's theory of 'even if,' the following statement is logically true iff the principle of conditional excluded is valid: (SE) If Q and if P wouldn't rule out Q, then Q even if P. Hence whatever intuitions support the validity of (SE) support the validity of Conditional Excluded Middle, too. Finally I show that Bennett's objection to John Bigelow's theory of the conditional can be turned into a (perhaps) more telling one, viz. that on (...) Bigelow's theory 'if P then Q' and 'if P and Q then R' do not jointly entail 'if P then R'. (shrink)

Until comparatively recently, say the middle of the last century, spinal cord injury was fatal as pressure sores and other infections took their toll. Those with severe brain injuries, unable to move or even communicate, fared even worse; without movement or feeding such patients were nursed until nature took its course. Over the last few decades medical and nursing advances have enabled some of these vegetative patients to survive for considerable time, provoking, at times, ethical and legal dilemmas. Though they (...) survived, without overt behaviour or clear communication their carers were frequently unsure how much residual function remained. Now real progress is occurring in this area thanks to the application of neuro-scientiﬁc methods by some outstanding groups of workers. Subjects with severe brain injury may begin in complete, unresponsive coma but then ‘lighten’ to one of three categories. In vegetative state (VS), patients are apparently awake but without evidence of voluntary behaviour and have no apparent awareness of self or environment, whilst in minimally conscious state (MCS) patients have some behaviour beyond the reﬂex but are not able to communicate eﬀectively. These conditions usually result from widespread brain damage at either or both cortical and subcortical levels due to injury or anoxia, though they can also be seen in end stage neurological conditions like Alzheimer’s. In locked in syndrome (LIS), patients ‘awake’ from coma, usually due to stroke, aware of their surroundings and their situation but unable to speak or move, beyond eye lid control and eye movement. For many, LIS will be recognised from Bauby’s extraordinary account in ‘The Diving Bell and the Butterﬂy,’ though, incidentally, it was presaged in Samuel Beckett’s novella ‘The Unnameable.’ LIS reﬂects a profound disconnection between brain and body, except for the upper cranial nerves involved in eyelid movement. The overriding question is how much awareness these patients have.. (shrink)
To what extent is imagination dependent on embodied experience? In attempting to answer such questions I consider the experiences of those who have to come to terms with altered neurological function, namely those with spinal cord injury at the neck. These people have each lost all sensation and movement below the neck. How might these new ways of living affect their imagination?
Traditionally, what we are conscious of in self-consciousness is something non-corporeal. But anti-Cartesian philosophers argue that the self is as much corporeal as it is mental. Because we have the sense of proprioception, a kind of body awareness, we are immediately aware of ourselves as bodies in physical space. In this debate the case histories of patients who have lost their sense of proprioception are clearly relevant. These patients do retain an awareness of themselves as corporeal beings, although they hardly (...) feel their bodies . They can initiate movements, and with the help of visual feedback learn to control them. It is shown that the traditional view of the self as immaterial is not supported by these cases. But the argument against this view has to be amended. It relies too much on bodily sensations, and misses the importance of active self-movement. (shrink)
