This dissertation argues for a "bundle thesis" of phenomenal consciousness: that the ways things seem to subjects are constituted by bundles of representational and functional properties. I argue that qualia are determined not only by intrinsic properties, but also by relational properties to other bodily and mental states . The view developed on the basis of this claim is called "phenomenal holism." ;Part I examines the current literature on phenomenal consciousness, sorting out various conceptual and historical issues. In particular, I (...) show that current research falls into two camps: that claiming there is no coherent view of phenomenal consciousness or of how it can be studied, and that claiming that phenomenal consciousness is constituted by non-relational and non-causal/functional/representational properties. Neither camp believes that materialist theories of consciousness are possible. ;Part II counters the specific objections these writers raise against materialist theories. First I show that some of the most prominent objections are founded upon an implicit and misguided assumption: that qualia are non-relational simples, based on what I call the segregationist intuition. Then, more specifically, I argue: that while Kripke's argument from a posteriori necessity against the identity-theory is committed to the absence of an appearance/reality distinction, its presumptions entail this distinction; and that the symmetrical development of the possibility of "hidden qualia" shows that absent qualia and zombie arguments against functionalism are absurd. This last argument is extended to argue against the possibility of inverted spectra. It is concluded that none of the standard objections to materialist theories carry significant weight. ;Part III turns to relational theories of consciousness, and supports an "integrationist intuition" about the mind. I first show that higher-order perception and higher-order thought theories are inadequate, in spite of correctly construing consciousness relationally. I then go on to develop the bundle theory, drawing support from empirical research on vision and pain. The dissertation concludes by defending phenomenal holism and integrationist views of mind more generally, and setting directions for future research. (shrink)

Little, Brown, 1992 Review by Glenn Branch on Jul 5th 1999 Volume: 3, Number: 27.

This introductory chapter attempts to clarify the philosophical, empirical, and theoretical bases on which a cognitive neuroscience approach to consciousness can be founded. We isolate three major empirical observations that any theory of consciousness should incorporate, namely (1) a considerable amount of processing is possible without consciousness, (2) attention is a prerequisite of consciousness, and (3) consciousness is required for some specific cognitive tasks, including those that require durable information maintenance, novel combinations of operations, or the spontaneous generation of intentional (...) behavior. We then propose a theoretical framework that synthesizes those facts: the hypothesis of a global neuronal workspace. This framework postulates that, at any given time, many modular cerebral networks are active in parallel and process information in an unconscious manner. An information becomes conscious, however, if the neural population that represents it is mobilized by top-down attentional amplification into a brain-scale state of coherent activity that involves many neurons distributed throughout the brain. The long-distance connectivity of these `workspace neurons' can, when they are active for a minimal duration, make the information available to a variety of processes including perceptual categorization, long-term memorization, evaluation, and intentional action. We postulate that this global availability of information through the workspace is what we subjectively experience as a conscious state. A complete theory of consciousness should explain why some cognitive and cerebral representations can be permanently or temporarily inaccessible to consciousness, what is the range of possible conscious contents, how they map onto specific cerebral circuits, and whether a generic neuronal mechanism underlies all of them. We confront the workspace model with those issues and identify novel experimental predictions. Neurophysiological, anatomical, and brain-imaging data strongly argue for a major role of prefrontal cortex, anterior cingulate, and the areas that connect to them, in creating the postulated brain-scale workspace.

Breaking new ground in the debate about the relation of mind and body, David Armstrong's classic text - first published in 1968 - remains the most compelling and comprehensive statement of the view that the mind is material or physical. In the preface to this new edition, the author reflects on the book's impact and considers it in the light of subsequent developments. He also provides a bibliography of all the key writings to have appeared in the materialist debate.

The thesis that there is a troublesome explanatory gap between the phenomenal aspects of experiences and the underlying physical and functional states is given a number of different interpretations. It is shown that, on each of these interpretations, the thesis is false. In supposing otherwise, philosophers have fallen prey to a cognitive illusion, induced largely by a failure to recognize the special character of phenomenal concepts.

The title of The Rediscovery of the Mind suggests the question "When was the mind lost?" Since most people may not be aware that it ever was lost, we must also then ask "Who lost it?" It was lost, of course, only by philosophers, by certain philosophers. This passed unnoticed by society at large. The "rediscovery" is also likely to pass unnoticed. But has the mind been rediscovered by the same philosophers who "lost" it? Probably not. John Searle is an (...) analytic philosopher, with some of the same notions as the positivists and behaviorists who rejected consciousness and "lost" the mind in the first place, but he also does not sound like the kind of reductionist who would have joined that crowd. His views, indeed, are sensible enough, and some of his insights so important, that it is a shame to find his thought profoundly limited by some of the same mistakes and prejudices that ruined philosophy, and not just philosophy of mind, under the influence of those positivists and behaviorists. There is enough of genuine value in his treatment, that it can easily be taken up and, with relatively slight modification, added to what is of permanent value in the history of philosophy. (shrink)

Presented here in a lucid, simple style is an extended defense of a behavioral and direct-realist theory of sense perception. Originally published in 1971. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These paperback editions preserve the original texts of these important books while presenting them in durable paperback editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich (...) scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

Do studies of perception without awareness and studies of perception without attention address a similar underlying concept of awareness? To answer this question, we compared qualitative differences in performance across variations in stimulus quality with qualitative differences in performance across variations in the direction of attention . The qualitative differences were based on three different phenomena: Stroop priming, false recognition, and exclusion failure. In all cases, variations in stimulus quality and variations in the direction of attention led to parallel findings. (...) These results suggest that perception with and without awareness and perception with and without attention are equivalent ways of describing the same underlying process distinction. (shrink)

This book argues that we are not equipped to understand the workings of conciousness, despite its objective naturalness.

In this book, William Lycan reviews the diverse philosophical views on consciousness--including those of Kripke, Block, Campbell, Sellars, and Casteneda--and ..

Two Themes to the Course: a.) How are we to understand the contrast between direct and indirect or immediate and mediate perception? b.) Is there any cogent reason to think we don’t have sense experience of the world around us?

Owen Flanagan argues that we are on the way to understanding consciousness and its place in the natural order.

The book is an extended study of the problem of consciousness. After setting up the problem, I argue that reductive explanation of consciousness is impossible , and that if one takes consciousness seriously, one has to go beyond a strict materialist framework. In the second half of the book, I move toward a positive theory of consciousness with fundamental laws linking the physical and the experiential in a systematic way. Finally, I use the ideas and arguments developed earlier to defend (...) a form of strong artificial intelligence and to analyze some problems in the foundations of quantum mechanics. (shrink)

This volume is an introduction to contemporary debates in the philosophy of mind. In particular, the author focuses on the controversial "eliminativist" and "instrumentalist" attacks - from philosophers such as of Quine, Dennett, and the Churchlands - on our ordinary concept of mind. In so doing, Rey offers an explication and defense of "mental realism", and shows how Fodor's representational theory of mind affords a compelling account of much of our ordinary mental talk of beliefs, hopes, and desires.
