By definition zombies would be physically and behaviourally just like us, but not conscious. This currently very influential idea is a threat to all forms of physicalism, and has led some philosophers to give up physicalism and become dualists. It has also beguiled many physicalists, who feel forced to defend increasingly convoluted explanations of why the conceivability of zombies is compatible with their impossibility. Robert Kirk argues that the zombie idea depends on an incoherent view of the nature of phenomenal (...) consciousness. His book has two main aims. One is to demolish the zombie idea once and for all. There are plenty of objections to it in the literature, but they lack intuitive appeal. He offers a striking new argument which reveals fundamental confusions in the implied conception of consciousness. The book's other main contribution is to develop a fresh and original approach to the true nature of phenomenal consciousness. Kirk argues that a necessary condition is a 'basic package' of capacities. An important component of his argument is that the necessary cognitive capacities are not as sophisticated as is often assumed. By focusing on humbler creatures than ourselves he avoids some of the distracting complications of our sophisticated forms of cognition. The basic package does not seem to be sufficient for phenomenal consciousness. What is also needed is 'direct activity' - a special feature of the way the events which constitute incoming perceptual information affect the system. This is an integrated process, to be conceived of holistically, and contrasts sharply with what is often called the 'availability' or 'poisedness' of perceptual information. This original, penetrating, and readable book will be of interest to all who have a serious concern with the nature of consciousness: not only professional philosophers and students, but psychologists and neuroscientists.

The interest of this is threefold. First, patients with altered states of consciousness continue to represent a major clinical problem in terms of clinical assessment of consciousness and daily management.

Topics include immortality; materlialism; Descartes's 'Divisibility Argument' for dualism; the Argument from introspection'; the problems with..

In this book philosophers, physicists, psychologists, neurophysiologists, computer scientists, and others address this central topic in the growing discipline..

The contributions to this book are original articles, representing a cross-section of current philosophical work on consciousness and thereby allowing students and readers from other disciplines to acquaint themselves with the very latest debate, so that they can then pursue their own research interests more effectively. The volume includes a bibliography on consciousness in philosophy, cognitive science and brain research, covering the last 25 years and consisting of over 1000 entries in 18 thematic sections, compiled by David Chalmers and Thomas (...) Metzinger. (shrink)

Ignorance and Imagination advances a novel way to resolve the central philosophical problem about the mind: how it is that consciousness or experience fits into a larger naturalistic picture of the world. The correct response to the problem, Stoljar argues, is not to posit a realm of experience distinct from the physical, nor to deny the reality of phenomenal experience, nor even to rethink our understanding of consciousness and the language we use to talk about it. Instead, we should view (...) the problem itself as a consequence of our ignorance of the relevant physical facts, Stoljar shows that this change of orientation is well motivated historically, empirically, and philosophically, and that it has none of the side effects it is sometimes thought to have. The result is a philosophical perspective on the mind that has a number of far-reaching consequences: for consciousness studies, for our place in nature, and for the way we think about the relationship between philosophy and science.

This pioneering book explores in depth the role of neurotransmitters in conscious awareness. The central aim is to identify common neural denominators of conscious awareness, informed by the neurochemistry of natural, drug induced and pathological states of consciousness. Chemicals such as acetylcholine and dopamine, which bridge the synaptic gap between neurones, are the 'neurotransmitters in mind' that form the substance of the volume, which is essential reading for all who believe that unravelling mechanisms of consciousness must include these vital systems (...) of the brain.Up-to-date information is provided on: Psychological domains of attention, motivation, memory, sleep and dreaming that define normal states of consciousness. Effects of chemicals that alter or abolish consciousness, including hallucinogens and anaesthetics. Disorders of the brain such as dementia, schizophrenia and depression considered from the novel perspective of the way these affect consciousness, and how this might relate to disturbances in neurotransmission.(Series B).

Rupert Sheldrake, one of the world's preeminent biologists, has revolutionized scientific thinking with his vision of a living, developing universe--one with its own inherent memory. In The Rebirth of Nature, Sheldrake urges us to move beyond the centuries-old mechanistic view of nature, explaining why we can no longer regard the world as inanimate and purposeless. Sheldrake shows how recent developments in science itself have brought us to the threshold of a new synthesis in which traditional wisdom, intuitive experience, and scientific (...) insight can be mutually enriching.

This paper reviews the literature concerning the neural correlates of the self, the relationship between self and memory and the profile of memory impairments in Alzheimer’s disease and explores the relationship between the preservation of the self and anosognosia in this condition. It concludes that a potential explanation for anosognosia in AD is a lack of updating of personal information due to the memory impairments characteristic of this disease. We put forward the hypothesis that anosognosia is due in part to (...) the “petrified self.”. (shrink)

"How can people come to believe that their poodle is an impostor? Or see colors in numbers? Francis Crick, co-discoverer of DNA, said of V. S. Ramachandran's first book, "The patients he describes are fascinating, and his experiments on them are both simple and ingenious." With his unique energy and style Ramachandran now shares his insights into the mind from such everyday human experiences as pain, sight, and the appreciation of beauty to the ultimate philosophical conundrums of consciousness."--BOOK JACKET.

Moral judgments, whether delivered in ordinary experience or in the courtroom, depend on our ability to infer intentions. We forgive unintentional or accidental harms and condemn failed attempts to harm. Prior work demonstrates that patients with damage to the ventromedial prefrontal cortex deliver abnormal judgments in response to moral dilemmas and that these patients are especially impaired in triggering emotional responses to inferred or abstract events, as opposed to real or actual outcomes. We therefore predicted that VMPC patients would deliver (...) abnormal moral judgments of harmful intentions in the absence of harmful outcomes, as in failed attempts to harm. This prediction was confirmed in the current study: VMPC patients judged attempted harms, including attempted murder, as more morally permissible relative to controls. These results highlight the critical role of the VMPC in processing harmful intent for moral judgment. (shrink)

The current paper examines the functional contributions of the amygdala and ventromedial prefrontal cortex (vmPFC) and the evidence that the functioning of these systems is compromised in individuals with psychopathy. The amygdala is critical for the formation of stimulus–reinforcement associations, both punishment and reward based, and the processing of emotional expressions. vmPFC is critical for the representation of reinforcement expectancies and, owing to this, decision making. Neuropsychological and neuroimaging data from individuals with psychopathy are examined. It is concluded that these (...) critical functions of the amygdala and vmPFC, and their interaction, are compromised in individuals with the disorder. It is argued that these impairments lead to the development of psychopathy. (shrink)

William S. Robinson has for many years written insightfully about the mind-body problem. In Understanding Phenomenal Consciousness he focuses on sensory experience and perception qualities such as colours, sounds and odours to present a dualistic view of the mind, called Qualitative Event Realism, that goes against the dominant materialist views. This theory is relevant to the development of a science of consciousness which is now being pursued not only by philosophers but by researchers in psychology and the brain sciences. This (...) provocative book will interest students and professionals who work in the philosophy of mind and will also have cross-disciplinary appeal in cognitive psychology and the brain sciences.

A common feature of the antisocial, rule-breaking behavior that is central to criminal, violent and psychopathic individuals is the failure to follow moral guidelines. This review summarizes key findings from brain imaging research on both antisocial behavior and moral reasoning, and integrates these findings into a neural moral model of antisocial behavior. Key areas found to be functionally or structurally impaired in antisocial populations include dorsal and ventral regions of the prefrontal cortex (PFC), amygdala, hippocampus, angular gyrus, anterior cingulate and (...) temporal cortex. Regions most commonly activated in moral judgment tasks consist of the polar/medial and ventral PFC, amygdala, angular gyrus and posterior cingulate. It is hypothesized that the rule-breaking behavior common to antisocial, violent and psychopathic individuals is in part due to impairments in some of the structures (dorsal and ventral PFC, amygdala and angular gyrus) subserving moral cognition and emotion. Impairments to the emotional component that comprises the feeling of what is moral is viewed as the primary deficit in antisocials, although some disruption to the cognitive and cognitive-emotional components of morality (particularly self-referential thinking and emotion regulation) cannot be ruled out. While this neurobiological predisposition is likely only one of several biosocial processes involved in the etiology of antisocial behavior, it raises significant moral issues for the legal system and neuroethics.
