Rethinking Consciousness A Scientific Theory Of Subjective Experience

“A first-class intellectual adventure.” —Brian Greene, author of Until the End of Time Illuminating his groundbreaking theory of consciousness, known as the attention schema theory, Michael S. A. Graziano traces the evolution of the mind over millions of years, with examples from the natural world, to show how neurons first allowed animals to develop simple forms of attention and then to construct awareness of the external world and of the self. His theory has fascinating implications for the future: it may point the way to engineers for building consciousness artificially, and even someday taking the natural consciousness of a person and uploading it into a machine for a digital afterlife.

"Hidden beneath consciousness, the brain mechanisms of personal space affect every aspect of our lives - social, emotional, cultural, and practical"--

What is consciousness and how can a brain, a mere collection of neurons, create it? In Consciousness and the Social Brain, Princeton neuroscientist Michael Graziano lays out an audacious new theory to account for the deepest mystery of them all. The human brain has evolved a complex circuitry that allows it to be socially intelligent. This social machinery has only just begun to be studied in detail. One function of this circuitry is to attribute awareness to others: to compute that person Y is aware of thing X. In Graziano's theory, the machinery that attributes awareness to others also attributes it to oneself. Damage that machinery and you disrupt your own awareness. Graziano discusses the science, the evidence, the philosophy, and the surprising implications of this new theory.

A thought-provoking argument that consciousness—more widespread than previously assumed—is the feeling of being alive, not a type of computation or a clever hack In The Feeling of Life Itself, Christof Koch offers a straightforward definition of consciousness as any subjective experience, from the most mundane to the most exalted—the feeling of being alive. Psychologists study which cognitive operations underpin a given conscious perception. Neuroscientists track the neural correlates of consciousness in the brain, the organ of the mind. But why the brain and not, say, the liver? How can the brain—three pounds of highly excitable matter, a piece of furniture in the universe, subject to the same laws of physics as any other piece—give rise to subjective experience? Koch argues that what is needed to answer these questions is a quantitative theory that starts with experience and proceeds to the brain. In The Feeling of Life Itself, Koch outlines such a theory, based on integrated information. Koch describes how the theory explains many facts about the neurology of consciousness and how it has been used to build a clinically useful consciousness meter. The theory predicts that many, and perhaps all, animals experience the sights and sounds of life; consciousness is much more widespread than conventionally assumed. Contrary to received wisdom, however, Koch argues that programmable computers will not have consciousness. Even a perfect software model of the brain is not conscious. Its simulation is fake consciousness. Consciousness is not a special type of computation—it is not a clever hack. Consciousness is about being.

The second edition of the seminal work in the field—revised, updated, and extended In Philosophical Foundations of Neuroscience, M.R. Bennett and P.M.S. Hacker outline and address the conceptual confusions encountered in various neuroscientific and psychological theories. The result of a collaboration between an esteemed philosopher and a distinguished neuroscientist, this remarkable volume presents an interdisciplinary critique of many of the neuroscientific and psychological foundations of modern cognitive neuroscience. The authors point out conceptual entanglements in a broad range of major neuroscientific and psychological theories—including those of such neuroscientists as Blakemore, Crick, Damasio, Dehaene, Edelman, Gazzaniga, Kandel, Kosslyn, LeDoux, Libet, Penrose, Posner, Raichle and Tononi, as well as psychologists such as Baar, Frith, Glynn, Gregory, William James, Weiskrantz, and biologists such as Dawkins, Humphreys, and Young. Confusions arising from the work of philosophers such as Dennett, Chalmers, Churchland, Nagel and Searle are subjected to detailed criticism. These criticisms are complemented by constructive analyses of the major cognitive, cogitative, emotional and volitional attributes that lie at the heart of cognitive neuroscientific research. Now in its second edition, this groundbreaking work has been exhaustively revised and updated to address current issues and critiques. New discussions offer insight into functional magnetic resonance imaging (fMRI), the notions of information and representation, conflict monitoring and the executive, minimal states of consciousness, integrated information theory and global workspace theory. The authors also reply to criticisms of the fundamental arguments posed in the first edition, defending their conclusions regarding mereological fallacy, the necessity of distinguishing between empirical and conceptual questions, the mind-body problem, and more. Essential as both a comprehensive reference work and as an up-to-date critical review of cognitive neuroscience, this landmark volume: Provides a scientifically and philosophically informed survey of the conceptual problems in a wide variety of neuroscientific theories Offers a clear and accessible presentation of the subject, minimizing the use of complex philosophical and scientific jargon Discusses how the ways the brain relates to the mind affect the intelligibility of neuroscientific research Includes fresh insights on mind-body and mind-brain relations, and on the relation between the notion of person and human being Features more than 100 new pages and a wealth of additional diagrams, charts, and tables Continuing to challenge and educate readers like no other book on the subject, the second edition of Philosophical Foundations of Neuroscience is required reading not only for neuroscientists, psychologists, and philosophers, but also for academics, researchers, and students involved in the study of the mind and consciousness.

Consciousness is widely perceived as one of the most fundamental, interesting and difficult problems of our time. However, we still know next to nothing about the relationship between consciousness and the brain and we can only speculate about the consciousness of animals and machines. Human and Machine Consciousness presents a new foundation for the scientific study of consciousness. It sets out a bold interpretation of consciousness that neutralizes the philosophical problems and explains how we can make scientific predictions about the consciousness of animals, brain-damaged patients and machines. Gamez interprets the scientific study of consciousness as a search for mathematical theories that map between measurements of consciousness and measurements of the physical world. We can use artificial intelligence to discover these theories and they could make accurate predictions about the consciousness of humans, animals and artificial systems. Human and Machine Consciousness also provides original insights into unusual conscious experiences, such as hallucinations, religious experiences and out-of-body states, and demonstrates how ‘designer’ states of consciousness could be created in the future. Gamez explains difficult concepts in a clear way that closely engages with scientific research. His punchy, concise prose is packed with vivid examples, making it suitable for the educated general reader as well as philosophers and scientists. Problems are brought to life in colourful illustrations and a helpful summary is given at the end of each chapter. The endnotes provide detailed discussions of individual points and full references to the scientific and philosophical literature.

The problem of how the brain produces consciousness, subjectivity and "something it is like to be" remains one of the greatest challenges to a complete science of the natural world. While various scientists and philosophers approach the problem from their own unique perspectives and in the terms of their own respective fields, Biophysics of Consciousness: A Foundational Approach attempts a consilience across disparate disciplines to explain how it is possible that an objective brain produces subjective experience. This volume unites the crème de la crème of physicists, neuroscientists, and psychiatrists in the attempt to understand consciousness through a foundational approach encompassing ontological, evolutionary, neurobiological, and Freudian interpretations with the focus on conscious phenomena occurring in the brain. By integrating the perspectives of these diverse disciplines with the latest research and theories on the biophysics of the brain, the book tries to explain how consciousness can be an adaptive and causal element in the natural world.

In Consciousness We Trust is a synthesis of Hakwan Lau's 20-year research programme exploring the neuroscience of consciousness. Discussing studies from his own laboratory, Lau uses various neuroscience techniques to address challenging philosophical questions about the nature of our subjective experience. Considering the qualitative nature of subjective experience, the book reviews the current cognitive neuroscience literature on conscious perception, attention, and metacognition and puts forward a mechanistic account of experience through the context of personal journey. Chapters cover different major theoretical positions, to relate the nature of consciousness to relevant phenomena such as attention, metacognition, rational control, emotion, and sense of agency. This is a must-read for graduate students and researchers in cognitive neuroscience and philosophy, and an important contribution to the consciousness literature.
