Why the central problem in neuroscience is mirrored in physics.

Non-technical introduction to Giulio Tononi's Integrated Information Theory of consciousness.

This entry focuses on two of the more historically important monisms: existence monism and priority monism . Existence monism targets concrete objects and counts by tokens. This is the doctrine that exactly one concrete object exists. Priority monism also targets concrete objects, but counts by basic tokens. This is the doctrine that exactly one concrete object is basic, which will turn out to be the classical doctrine that the whole is prior to its parts.

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.

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)

I present an argument for panpsychism: the thesis that everything is conscious, or at least that fundamental physical entities are conscious. The argument takes a Hegelian dialectical form. Panpsychism emerges as a synthesis of the thesis of materalism and the antithesis of dualism. In particular, the key premises of the causal argument for materialism and the conceivability argument for dualism are all accommodated by a certain version of panpsychism. This synthesis has its own antithesis in turn: panprotopsychism, the thesis that (...) fundamental physical entities are protoconscious, also accommodates the key premises. Panpsychism and panprotopsychism are synthesized under Russellian monism, and then face an antithesis, the combination problem. The question of whether there is a new synthesis remains open.

At any given time, a subject has a multiplicity of conscious experiences. A subject might simultaneously have visual experiences of a red book and a green tree, auditory experiences of birds singing, bodily sensations of a faint hunger and a sharp pain in the shoulder, the emotional experience of a certain melancholy, while having a stream of conscious thoughts about the nature of reality. These experiences are distinct from each other: a subject could experience the red book without the singing (...) birds, and could experience the singing birds without the red book. But at the same time, the experiences seem to be tied together in a deep way. They seem to be unified, by being aspects of a single encompassing state of consciousness. (shrink)

A contemporary form of panpsychism says that phenomenality is prevalent because all physical ultimates instantiate phenomenal or protophenomenal properties. According to priority cosmopsychism, an alternative to panpsychism that we propose in this chapter, phenomenality is prevalent because the whole cosmos instantiates phenomenal or protophenomenal properties. It says, moreover, that the consciousness of the cosmos is ontologically prior to the consciousness of ordinary individuals like us. Since priority cosmopsychism is a highly speculative view our aim in this chapter remains modest and (...) limited. Instead of providing a full defense of priority cosmopsychism, we try to show only the theoretical advantage of the view over panpsychism. Tis, however, by no means entails that we develop the view in logical space merely for its own sake. We offer instead a blueprint for a new alternative to panpsychism and explain how such a view avoids some of the most persistent problems for panpsychism while maintaining several of its strengths.

One of the most exciting aspects of this journal, of which I am proud to be an executive editor, is that it has become a venue in which so many distinct fields can interact on a single question, that of consciousness. I know of no other question, or journal, which has brought together so many voices, from so many fields, to swirl around a single topic. It is exciting both to provide a forum and to be a part of this (...) debate. In this article I would like to bring the findings of my somewhat unusual but increasingly accepted field -- mysticism-- to the discussion, for I think they may offer some helpful insights about consciousness. Why? When a biologist seeks to understand a complex phenomenon, one key strategy is to look to at it in its simplest form. Probably the most famous is the humble bacterium E. coli. Its simple gene structure has allowed us to understand much of the gene functioning of complex species. Similarly many biologists have turned to the `memory' of the simple sea slug to understand our own more kaleidoscopic memory. Freud and Durkheim both used totemism, which they construed as the simplest form of religion, to understand the complexities of religious life. The methodological principle is: to understand something complex turn to its simple forms. (shrink)
