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)

Computing Methodologies -- Artificial Intelligence.

The modern materialist approach to life has conspicuously failed to explain such central mind-related features of our world as consciousness, intentionality, meaning, and value. This failure to account for something so integral to nature as mind, argues philosopher Thomas Nagel, is a major problem, threatening to unravel the entire naturalistic world picture, extending to biology, evolutionary theory, and cosmology. Since minds are features of biological systems that have developed through evolution, the standard materialist version of evolutionary biology is fundamentally incomplete. (...) And the cosmological history that led to the origin of life and the coming into existence of the conditions for evolution cannot be a merely materialist history, either. An adequate conception of nature would have to explain the appearance in the universe of materially irreducible conscious minds, as such. Nagel's skepticism is not based on religious belief or on a belief in any definite alternative. In Mind and Cosmos, he does suggest that if the materialist account is wrong, then principles of a different kind may also be at work in the history of nature, principles of the growth of order that are in their logical form teleological rather than mechanistic. In spite of the great achievements of the physical sciences, reductive materialism is a world view ripe for displacement. Nagel shows that to recognize its limits is the first step in looking for alternatives, or at least in being open to their possibility. (shrink)

This article presents the case for an approach to consciousness that I call illusionism. This is the view that phenomenal consciousness, as usually conceived, is illusory. According to illusionists, our sense that it is like something to undergo conscious experiences is due to the fact that we systematically misrepresent them as having phenomenal properties. Thus, the task for a theory of consciousness is to explain our illusory representations of phenomenality, not phenomenality itself, and the hard problem is replaced by the (...) illusion problem. Although it has had powerful defenders, illusionism remains a minority position, and it is often dismissed as failing to take consciousness seriously. This article seeks to rebut this accusation. It defines the illusionist programme, outlines its attractions, and defends it against some common objections. It concludes that illusionism is a coherent and attractive approach, which deserves serious consideration. (shrink)

A breathtaking look at the new science that can track consciousness deep in the brain How does our brain generate a conscious thought? And why does so much of our knowledge remain unconscious? Thanks to clever psychological and brain-imaging experiments, scientists are closer to cracking this mystery than ever before. In this lively book, Stanislas Dehaene describes the pioneering work his lab and the labs of other cognitive neuroscientists worldwide have accomplished in defining, testing, and explaining the brain events behind (...) a conscious state. We can now pin down the neurons that fire when a person reports becoming aware of a piece of information and understand the crucial role unconscious computations play in how we make decisions. The emerging theory enables a test of consciousness in animals, babies, and those with severe brain injuries. A joyous exploration of the mind and its thrilling complexities, Consciousness and the Brain will excite anyone interested in cutting-edge science and technology and the vast philosophical, personal, and ethical implications of finally quantifying consciousness.

How is consciousness possible? What biological purpose does it serve? And why do we value it so highly? In Soul Dust, the psychologist Nicholas Humphrey, a leading figure in consciousness research, proposes a startling new theory. Consciousness, he argues, is nothing less than a magical-mystery show that we stage for ourselves inside our own heads. This self-made show lights up the world for us and makes us feel special and transcendent. Thus consciousness paves the way for spirituality, and allows us, (...) as human beings, to reap the rewards, and anxieties, of living in what Humphrey calls the "soul niche." Tightly argued, intellectually gripping, and a joy to read, Soul Dust provides answers to the deepest questions. It shows how the problem of consciousness merges with questions that obsess us all--how life should be lived and the fear of death. Resting firmly on neuroscience and evolutionary theory, and drawing a wealth of insights from philosophy and literature, Soul Dust is an uncompromising yet life-affirming work--one that never loses sight of the majesty and wonder of consciousness.

The mind-body problem is widely seen as the great remaining challenge to science and philosophy. Why and how did matter evolve to take on the quality of mind? The author takes the reader to the edges of current knowledge and back to the beginning of time, before mind existed, and in doing so constructs a history of consciousness.

The purpose of this book is to build towards an explanation of just what the matter is.

Sensations represent our subjective 'take' on sensory stimulation — how we feel about red light falling on the retina, salt dissolving on the tongue, a thorn piercing the skin. They tell — in the language of phenomenal properties -- what the experience is like for us. In so far as they represent the reality of this subjective relationship, they cannot be said to be illusory. The relationship, magical as it may seem, is not being misrepresented as something it is not. (...) If anything, it is being represented as something 'super-real'. (shrink)

As the subtitle indicates, this book is concerned with the relationship between consciousness and the physical world. It recommends a novel and disturbingly pessimistic view about this topic that it calls “naturalistic mysterianism.” The view is naturalistic because it maintains that states of consciousness are reducible to physical properties of the brain. It counts as “mysterian” because it asserts that the physical properties in question are entirely beyond our ken—that they lie well beyond the scope of contemporary neuroscience, and quite (...) likely beyond the scope of any body of scientific knowledge that we might develop in the future. Naturalistic mysterianism thus affirms the unity of consciousness with the physical world, while also claiming that the nature of that unity will forever elude us, due to inherent limits of our cognitive capacities.

The sensation of red light falling on your eyes has something in common with the experience of looking at a cartoon in the New Yorker. The phenomenal quality of the sensation and the funniness of the joke are both properties of your subjective take on an external event and both arise in two steps. With sensations, your brain responds to signals from bodily sense organs with an internalized evaluative response; your mind reads this response and represents what it's like as (...) the subjective property of redness. With jokes, the cartoonist creates a clever drawing; your mind takes in the drawing and represents what it's like as the subjective property of funniness. This analogy -- deliberately deflationary -- helps elucidate the nature of phenomenal consciousness and its neural correlates, and exposes the 'hard problem' as a conceptual error. (shrink)

What unites the many selves that constitute the human mind? How is the self-binding problem solved? I argue that separate selves come to belong together as one Self as a result of their dynamic participation in creating a single life, rather as the members of an orchestra come to belong together as a result of their jointly creating a single work of music.
