The most remarkable fact about the universe is that certain parts of it are conscious. Somehow nature has managed to pull the rabbit of experience out of a hat made of mere matter. Making its own contribution to the current, lively debate about the nature of consciousness, Theories of Consciousness introduces variety of approaches to consciousness and explores to what extent scientific understanding of consciousness is possible. Including discussion of key figures, such as Descartes, Foder, Dennett and Chalmers, the book (...) covers identity theories, representational theories, intentionality, externalism, and the new information-based theories.

Consciousness fits uneasily into our conception of the natural world. On the most common conception of nature, the natural world is the physical world. But on the most common conception of consciousness, it is not easy to see how it could be part of the physical world. So it seems that to find a place for consciousness within the natural order, we must either revise our conception of consciousness, or revise our conception of nature. In twentieth-century philosophy, this dilemma is (...) posed most acutely in C. D. Broad’s The Mind and its Place in Nature . The phenomena of mind, for Broad, are the phenomena of consciousness. The central problem is that of locating mind with respect to the physical world. Broad’s exhaustive discussion of the problem culminates in a taxonomy of seventeen different views of the mental-physical relation.1 On Broad’s taxonomy, a view might see the mental as nonexistent , as reducible, as emergent, or as a basic property of a substance . The physical might be seen in one of the same four ways. So a four-by-four matrix of views results. At the end, three views are left standing: those on which mentality is an emergent characteristic of either a physical substance or a neutral substance, where in the latter case, the physical might be either emergent or delusive.

In this chapter, I survey what I call Lewisian approaches to modality: approaches that analyze modality in terms of concrete possible worlds and their parts. I take the following four theses to be characteristic of Lewisian approaches to modality. (1) There is no primitive modality. (2) There exists a plurality of concrete possible worlds. (3) Actuality is an indexical concept. (4) Modality de re is to be analyzed in terms of counterparts, not transworld identity. After an introductory section in which (...) I motivate analyzing modality in terms of possible worlds, I devote one section to each of these four theses. For each thesis, I take Lewis’s interpretation and defense as my starting point. I then consider and endorse alternative ways of accepting the thesis, some of which disagree substantially with Lewis’s interpretation or defense. There is more than one way to be a Lewisian about modality. (shrink)

The functionalist view of the nature of the mind is now widely accepted. Like behaviorism and physicalism, functionalism seeks to answer the question "What are mental states?" I shall be concerned with identity thesis formulations of functionalism. They say, for example, that pain is a functional state, just as identity thesis formulations of physicalism say that pain is a physical state.

The generation problem is to explain how material configurations or processes can produce conscious experience. David Chalmers urges that this is what makes the problem of consciousness really difficult. He proposes to side-step the generation problem by proposing that consciousness is an absolutely fundamental feature of the world. I am inclined to agree that the generation problem is real and believe that taking consciousness to be fundamental is promising. But I take issue with Chalmers about what it is to be (...) a fundamental feature of the world. In fact, I argue that taking the idea seriously ought to lead to some form of panpsychism. Powerful objections have been advanced against panpsychism, but I attempt to outline a form of the doctrine which can evade them. In the end, I suspect that we will face a choice between panpsychism and rethinking the legitimacy of the generation problem itself. (shrink)

1 Non-reductive physicalists deny that there is any explanation of mentality in purely physical terms, but do not deny that the mental is entirely determined by and constituted out of underlying physical structures. There are important issues about the stability of such a view which teeters on the edge of explanatory reductionism on the one side and dualism on the other (see Kim 1998). 2 Save perhaps for eliminative materialism (see Churchland 1981 for a classic exposition). In fact, however, while.

David Ray Griffin develops a third form of realism, one that resolves the basic problem (common to dualism and materialism) of the continued acceptance of the Cartesian view of matter.

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)

What place does consciousness have in the natural world? If we reject materialism, could there be a credible alternative? In one classic example, philosophers ask whether we can ever know what is it is like for bats to sense the world using sonar. It seems obvious to many that any amount of information about a bat's physical structure and information processing leaves us guessing about the central questions concerning the character of its experience. A Place for Consciousness begins with reflections (...) on the existence of this gap. Is it just a psychological shortcoming in our merely human understanding of the physical world? Is it a trivial consequence of the simple fact that we just cannot be bats? Or does it mean there really are facts about consciousness over and above the physical facts? If so, what does consciousness do? Why does it exist? Rosenberg sorts out these problems, especially those centering on the causal role of consciousness. He introduces a new paradigm called Liberal Naturalism for thinking about what causation is, about the natural world, and about how to create a detailed model to go along with the new paradigm. Arguing that experience is part of the categorical foundations of causality, he shows that within this new paradigm there is a place for something essentially like consciousness in all its traditional mysterious respects. A striking feature of Liberal Naturalism is that its central tenets are motivated independently of the mind-body problem, by analyzing causation itself. Because of this approach, when consciousness shows up in the picture it is not introduced in an ad hoc way, and its most puzzling features can be explained from first principles. Ultimately, Rosenberg's final solution gives consciousness a causally important role without supposing either that it is physical or that it interacts with the physical. (shrink)

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)

In The Emergent Self, William Hasker joins one of the most heated debates in contemporary analytic philosophy, that over the nature of mind.

This paper raises complication for the standard interpretive view of Liebniz's mature metaphysical system as idealist. Body-realist affirmations are found in his writings up to his death, in bulk and diversity very difficult to accommodate to phenomenalist or idealist construal. Claims of Leibnizian inconsistency and indecisiveness do not seem adequately to account for them. The view that body is real for Liebniz, though not a substance, is explored. Alternative non-idealist interpretations of the system are considered, the most plausible argued to (...) be a variety of dualism. At the same time, dialectical features of Leibnizian philosophy make it a matter of proper caution not to settle emphatically on a decided conclusion of the issue. (shrink)

I argue Leibniz could not have been a dualist since his notion of matter is not defined by extension but by mentalistic "primitive passive force." So Leibniz was some kind of idealist. However, Leibniz was neither a phenomenal idealist like Berkeley nor a conceptualist idealist like Hegel. Instead, despite some suggestions in favor of the latter kind of idealism, Leibniz must be regarded as an idealist who admitted extraconceptual considerations irreducible to materialism.
