Computational Functionalism

Reflexive monism is, in essence, an ancient view of how consciousness relates to the material world that has, in recent decades, been resurrected in modern form. In this paper I discuss how some of its basic features differ from both dualism and variants of physicalist and functionalist reductionism, focusing on those aspects of the theory that challenge deeply rooted presuppositions in current Western thought. I pay particular attention to the ontological status and seeming “out-thereness” of the phenomenal world and to how the “phenomenal world” relates to the “physical world”, the “world itself”, and processing in the brain. In order to place the theory within the context of current thought and debate, I address questions that have been raised about reflexive monism in recent commentaries and also evaluate competing accounts of the same issues offered by “transparency theory” and by “biological naturalism”. I argue that, of the competing views on offer, reflexive monism most closely follows the contours of ordinary experience, the findings of science, and common sense.

The authors argue that the consciousness debate inhabits the same problem space today as it did in the 17th century. They attribute the lack of progress to a mindset still polarized by Descartes’ real distinction between mind and body, resulting in a standoff between humanistic and scientistic approaches. They suggest that consciousness can be adequately studied only by a multiplicity of disciplines so that the paramount problem is how to integrate diverse disciplinary perspectives into a coherent metatheory. Process philosophy is well qualified to attempt such a synthesis. The rationale for the volume is summed up in the book's unifying thesis: normal, focal-attentive consciousness is not the sui generis phenomenon it is usually taken to be, but part of a wider spectrum of experience (including marginal, deviant, and non-human experience) that can only be studied by approaches as diverse as phenomenology, psycho- and neuropathology, biology, and zoology

This paper replies to the first 36 commentaries on my target article on “Is human information processing conscious?” (Behavioral and Brain Sciences, 1991, pp. 651-669). The target article focused largely on experimental studies of how consciousness relates to human information processing, tracing their relation from input through to output, while discussion of the implications of the findings both for cognitive psychology and philosophy of mind was relatively brief. The commentaries reversed this emphasis, and so, correspondingly, did the reply. The sequence of topics in the reply roughly follows that of the target article. The discussion begins with a reconsideration of the details of the empirical findings, whether they can be extrapolated to non-laboratory settings, and the extent to which one can rely on their use of subjective reports. This is followed by an in-depth discussion of what is meant by “conscious processing” and of how phenomenal consciousness relates to attentional processing. We then turn to broader philosophical and theoretical issues. I point out some of the reasons why I do not support epiphenomenalism, dualist-interactionism, or reductionism, and elaborate on how first- and third-person views of the mind can be regarded as complementary and mutually irreducible. I suggest how the relation of conscious experiences to their neural correlates can be understood in terms of a dual-aspect theory of information, and how this might be used to resolve some of the paradoxes surrounding the causal interactions of consciousness and brain. I also suggest that, viewed from a first-person perspective, consciousness gives purpose to existence, which allows a different way of viewing its role in evolution.

The sequence of topics in this reply roughly follows that of the target article. The latter focused largely on experimental studies of how consciousness relates to human information processing, tracing their relation from input through to output. The discussion of the implications of the findings both for cognitive psychology and philosophy of mind was relatively brief. The commentaries reverse this emphasis, and so, correspondingly, does the reply.

From the back cover:
Understanding Consciousness, 2nd Edition provides a unique survey and evaluation of consciousness studies, along with an original analysis of consciousness that combines scientific findings, philosophy and common sense. Building on the widely praised first edition, this new edition adds fresh research, and deepens the original analysis in a way that reflects some of the fundamental changes in the understanding of consciousness that have taken place over the last 10 years.

The book is divided into three parts; Part one surveys current theories of consciousness, evaluating their strengths and weaknesses. Part two reconstructs an understanding of consciousness from first principles, starting with its phenomenology, and leading to a closer examination of how conscious experience relates to the world described by physics and information processing in the brain. Finally, Part three deals with some of the fundamental issues such as what consciousness is and does, and how it fits into to the evolving universe. As the structure of the book moves from a basic overview of the field to a successively deeper analysis, it can be used both for those new to the subject and for more established researchers.

Understanding Consciousness tells a story with a beginning, middle and end in a way that integrates the philosophy of consciousness with the science. Overall, the book provides a unique perspective on how to address the problems of consciousness and as such, will be of great interest to psychologists, philosophers, neuroscientists and other professionals concerned with mind/body relationships, and all who are interested in this subject.
