The search for neural correlates of consciousness (or NCCs) is arguably the cornerstone in the recent resurgence of the science of consciousness. The search poses many difficult empirical problems, but it seems to be tractable in principle, and some ingenious studies in recent years have led to considerable progress. A number of proposals have been put forward concerning the nature and location of neural correlates of consciousness. A few of these include.

This is the one and only book by the pioneer of the identity theory of mind. The collection focuses on Place's philosophy of mind and his contributions to neighboring issues in metaphysics and epistemology. It includes an autobiographical essay as well as a recent paper on the function and neural location of consciousness.

A transcript of three lectures, given at Princeton University in 1970, which deals with (inter alia) debates concerning proper names in the philosophy of language.

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 Mental and the Physical was first published in 1967. Minnesota Archive Editions uses digital technology to make long-unavailable books once again accessible, and are published unaltered from the original University of Minnesota Press editions. Professor Feigl's essay "The 'Mental' and the 'Physical'" has provoked a great deal of comment, criticism, and discussion since it first appeared as a part of the content of Volume II of the Minnesota Studies in the Philosophy of Science about ten years ago. Now Professor (...) Feigl takes account of the critical discussions and presents his own comments with respect to the most important points raised in the criticisms. The essay itself is presented here in full, along with the postscript. The British Journal for the Philosophy of Science has called the essay "a 'super-colossal' survey of the mind-body problem." In its review of the earlier book containing the essay, Thought said: "This essay deserves careful reading by every philosopher concerned with genuine philosophical dialogue.". (shrink)

The claim of the multiple realizability of mental states by brain states has been a major feature of the dominant philosophy of mind of the late 20th century. The claim is usually motivated by evidence that mental states are multiply realized, both within humans and between humans and other species. We challenge this contention by focusing on how neuroscientists differentiate brain areas. The fact that they rely centrally on psychological measures in mapping the brain and do so in a comparative (...) fashion undercuts the likelihood that, at least within organic life forms, we are likely to find cases of multiply realized psychological functions.

The only sensible solution to the mind-body problem is a type-type identity theory. I wish to argue for a version of Type-Type identity theory that withstands the usual seemingly fatal objections, which I call ‘R-Type Identity Theory’ and which has three claims. First, an identity theory does not entail ‘reducing’ or ‘eliminating’ one set of things to or in favor of another set of things and introduces epidentity (treating identified relata as distinct). Secondly, pain and what-it-is-like to be in pain (...) are distinguishable and introduces frigid stipulation (a pragmatic rather than semantic property by which we stipulate reference). Finally there may be more than one type of mental state in question and introduces subtypes (a pained brainless Martian is evidence that their state is a pain subtype). With the standard objections to identity theory taken care of we are free to embrace the only truly satisfying, non-Cartesian, philosophy of mind. (shrink)

1. My primary aim in this paper is to set the stage for a discussion of some of the central themes in the so-called "identity" approach to the mind-body problem. I have particularly in mind Herbert Feigl's elaborate statement and defense of this approach in Volume II of the Minnesota Studies. A secondary, but more constructive, purpose is to bring out some of the reasons which incline me to think that the theory is either very exciting but false, or true (...) but relatively uninteresting.

One of the distinctive properties of conscious states is the peculiar self- awareness implicit in them. Two rival accounts of this self-awareness are discussed. According to a Neo-Brentanian account, a mental state M is conscious iff M represents its very own occurrence. According to the Higher-Order Monitoring account, M is merely accompanied by a numerically distinct representation of its occurrence. According to both, then, M is conscious in virtue of figuring in a higher-order content. The disagreement is over the question (...) whether the higher-order content is carried by M itself or by a differ- ent state. While the Neo-Brentanian theory is phenomenologically more attractive, it is often felt to be somewhat mysterious. It is argued that the difference between the Neo- Brentanian and Higher-Order Monitoring theories is smaller and more empirical than may initially seem, and that the Neo-Brentanian theory can be readily demystified. These considerations make it prima facie preferable to the Higher-Order Monitoring theory. (shrink)

In Natural Minds Thomas Polger advocates, and defends, the philosophical theory that mind equals brain -- that sensations are brain processes -- and in doing so brings the mind-brain identity theory back into the philosophical debate about consciousness. The version of identity theory that Polger advocates holds that conscious processes, events, states, or properties are type- identical to biological processes, events, states, or properties -- a "tough-minded" account that maintains that minds are necessarily indentical to brains, a position held by (...) few current identity theorists. Polger's approach to what William James called the "great blooming buzzing confusion" of consciousness begins with the idea that we need to know more about brains in order to understand consciousness fully, but recognizes that biology alone cannot provide the entire explanation. Natural Minds takes on issues from philosophy of mind, philosophy of science, and metaphysics, moving freely among them in its discussion.Polger begins by answering two major objections to identity theory -- Hilary Putnam's argument from multiple realizability and Saul Kripke's modal argument against mind-brain identity. He then offers a detailed account of functionalism and functional realization, which offer the most serious obstacle to consideration of identity theory. Polger argues that identity theory can itself satisfy the kind of explanatory demands that are often believed to favor functionalism. (shrink)
