Ever since its discovery nearly thirty years ago, the phenomenon of blindsight—vision without visual consciousness—has been the source of great controversy in the philosophy of mind, psychology, and the neurosciences. Despite the fact that blindsight is widely acknowledged to be a critical test-case for theories of mind, Blindsight and the Nature of Consciousness is the first extended treatment of the phenomenon from a philosophical perspective. Holt argues, against much received wisdom, for a thorough-going materialism—the view not only that mental states are brain states, but (much more controversially) that mental properties are physical as well. Designed not only for philosophers and scientists, Blindsight and the Nature of Consciousness has something to say to anyone interested in the mystery of the human mind and in how philosophers and scientists are working toward solving that mystery.

Hugo and Shirley Jackson award-winning Peter Watts stands on the cutting edge of hard SF with his acclaimed novel, Blindsight Two months since the stars fell... Two months of silence, while a world held its breath. Now some half-derelict space probe, sparking fitfully past Neptune's orbit, hears a whisper from the edge of the solar system: a faint signal sweeping the cosmos like a lighthouse beam. Whatever's out there isn't talking to us. It's talking to some distant star, perhaps. Or perhaps to something closer, something en route. So who do you send to force introductions with unknown and unknowable alien intellect that doesn't wish to be met? You send a linguist with multiple personalities, her brain surgically partitioned into separate, sentient processing cores. You send a biologist so radically interfaced with machinery that he sees x-rays and tastes ultrasound. You send a pacifist warrior in the faint hope she won't be needed. You send a monster to command them all, an extinct hominid predator once called vampire, recalled from the grave with the voodoo of recombinant genetics and the blood of sociopaths. And you send a synthesist—an informational topologist with half his mind gone—as an interface between here and there. Pray they can be trusted with the fate of a world. They may be more alien than the thing they've been sent to find. At the Publisher's request, this title is being sold without Digital Rights Management Software (DRM) applied.

Intended for anyone attempting to find their way through the large and confusingly interwoven philosophical literature on consciousness, this reader brings together most of the principal texts in philosophy (and a small set of related key works in neuropsychology) on consciousness through 1997, and includes some forthcoming articles. Its extensive coverage strikes a balance between seminal works of the past few decades and the leading edge of philosophical research on consciousness.As no other anthology currently does, The Nature of Consciousness provides a substantial introduction to the field, and imposes structure on a vast and complicated literature, with sections covering stream of consciousness, theoretical issues, consciousness and representation, the function of consciousness, subjectivity and the explanatory gap, the knowledge argument, qualia, and monitoring conceptions of consciousness. Of the 49 contributions, 18 are either new or have been adapted from a previous publication.

The phenomenon of `consciousness' is intrinsically related to one's awareness of one's self, of time, and of the physical world. What, then, can be learned about consciousness from people who have suffered brain damage such as amnesia which affects their awareness? This is the question explored by Lawrence Weiskrantz, a distinguished neuropsychologist who has worked with such patients over 30 years. Written in an engaging and accessible style, Consciousness Lost and Found provides a unique perspective on one of the most challenging issues in science today.

Studies of patients blind from damage to the neocortex have revealed that some can discriminate certain visual events within their 'blind' fields. They are not aware that they can do so, however - they think that they are only guessing. This book is an account of research into a particular case of this 'blindsight' phenomenon. It also discusses the historical and neurological background, and reviews other cases and issues. - ;Damage to a particular area of the brain - the neocortex - is generally understood to result in blindness. Studies of some patients suffering from this form of blindness have nevertheless revealed that they can discriminate certain types of visual events within their 'blind' fields. They are not aware that they can do so, however - they think that they are only guessing. This phenomenon has been termed 'blindsight'. The present book gives an account of research over a number of years into a particular case of blindsight, together with a discussion of the historical and neurological background, a review of cases reported by other investigators, and a number of theoretical and practical issues and implications. - ;PART I: Background; D.B.: Clinical history and early testing; PART II: Reaching for randomly located targets; 'Presence' versus 'absence'; Visual acuity; Movement thresholds; Discrimination of orientation; 'Form' discrimination; Detection with slow rate of onset; The natural blind-spot (optic disc) within the scotoma; Left versus right eye; Detection of direction of contrast; 'Waves'; Matching between impaired and intact fields; Matching within the impaired field; Double dissociations between form and detection; Standard situation; PART III: Review of other cases; Status, issues, and implications; References; Indexes. -

National Book Award Finalist: “This man’s ideas may be the most influential, not to say controversial, of the second half of the twentieth century.”—Columbus Dispatch At the heart of this classic, seminal book is Julian Jaynes's still-controversial thesis that human consciousness did not begin far back in animal evolution but instead is a learned process that came about only three thousand years ago and is still developing. The implications of this revolutionary scientific paradigm extend into virtually every aspect of our psychology, our history and culture, our religion—and indeed our future. “Don’t be put off by the academic title of Julian Jaynes’s The Origin of Consciousness in the Breakdown of the Bicameral Mind. Its prose is always lucid and often lyrical…he unfolds his case with the utmost intellectual rigor.”—The New York Times “When Julian Jaynes . . . speculates that until late in the twentieth millennium BC men had no consciousness but were automatically obeying the voices of the gods, we are astounded but compelled to follow this remarkable thesis.”—John Updike, The New Yorker “He is as startling as Freud was in The Interpretation of Dreams, and Jaynes is equally as adept at forcing a new view of known human behavior.”—American Journal of Psychiatry

Prepare for a different kind of singularity in Peter Watts' Echopraxia, the follow-up to the Hugo-nominated novel Blindsight It's the eve of the twenty-second century: a world where the dearly departed send postcards back from Heaven and evangelicals make scientific breakthroughs by speaking in tongues; where genetically engineered vampires solve problems intractable to baseline humans and soldiers come with zombie switches that shut off self-awareness during combat. And it's all under surveillance by an alien presence that refuses to show itself. Daniel Bruks is a living fossil: a field biologist in a world where biology has turned computational, a cat's-paw used by terrorists to kill thousands. Taking refuge in the Oregon desert, he's turned his back on a humanity that shatters into strange new subspecies with every heartbeat. But he awakens one night to find himself at the center of a storm that will turn all of history inside-out. Now he's trapped on a ship bound for the center of the solar system. To his left is a grief-stricken soldier, obsessed by whispered messages from a dead son. To his right is a pilot who hasn't yet found the man she's sworn to kill on sight. A vampire and its entourage of zombie bodyguards lurk in the shadows behind. And dead ahead, a handful of rapture-stricken monks takes them all to a meeting with something they will only call "The Angels of the Asteroids." Their pilgrimage brings Dan Bruks, the fossil man, face-to-face with the biggest evolutionary breakpoint since the origin of thought itself.

Charles Siewert presents a distinctive approach to consciousness that emphasizes our first-person knowledge of experience and argues that we should grant consciousness, understood in this way, a central place in our conception of mind and intentionality. Written in an engaging manner that makes its recently controversial topic accessible to the thoughtful general reader, this book challenges theories that equate consciousness with a functional role or with the mere availability of sensory information to cognitive capacities. Siewert argues that the notion of phenomenal consciousness, slighted in some recent theories, can be made evident by noting our reliance on first-person knowledge and by considering, from the subject's point of view, the difference between having and lacking certain kinds of experience. This contrast is clarified by careful attention to cases, both actual and hypothetical, indicated by research on brain-damaged patients' ability to discriminate visually without conscious visual experience--what has become known as "blindsight." In addition, Siewert convincingly defends such approaches against objections that they make an illegitimate appeal to "introspection." Experiences that are conscious in Siewert's sense differ from each other in ways that only what is conscious can--in phenomenal character--and having this character gives them intentionality. In Siewert's view, consciousness is involved not only in the intentionality of sense experience and imagery, but in that of nonimagistic ways of thinking as well. Consciousness is pervasively bound up with intelligent perception and conceptual thought: it is not mere sensation or "raw feel." Having thus understood consciousness, we can better recognize how, for many of us, it possesses such deep intrinsic value that life without it would be little or no better than death.

Consciousness is one of the most significant scientific problems today. Renewed interest in the nature of consciousness - a phenomenon long considered not to be scientifically explorable, as well as increasingly widespread availability of multimodal functional brain imaging techniques (EEG, ERP, MEG, fMRI and PET), now offer the possibility of detailed, integrated exploration of the neural, behavioral, and computational correlates of consciousness. The present volume aims to confront the latest theoretical insights in the scientific study of human consciousness with the most recent behavioral, neuroimaging, electrophysiological, pharmacological and neuropathological data on brain function in altered states of consciousness such as: brain death, coma, vegetative state, minimally conscious state, locked-in syndrome, dementia, epilepsy, schizophrenia, hysteria, general anesthesia, sleep, hypnosis, and hallucinations. 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. Second, the exploration of brain function in altered states of consciousness represents a unique lesional approach to the scientific study of consciousness and adds to the worldwide effort to identify the "neural correlate of consciousness". Third, new scientific insights in this field have major ethical and social implications regarding our care for these patients.
