In the first post World War II identity theories (e.g., Place 1956, Smart 1962), mind brain identities were held to be contingent. However, in work beginning in the late 1960's, Saul Kripke (1971, 1980) convinced the philosophical community that true identity statements involving names and natural kind terms are necessarily true and furthermore, that many such necessary identities can only be known a posteriori. Kripke also offered an explanation of the a posteriori nature of ordinary theoretical identities such as that water = H2O. We identify the kinds and substances involved in theoretical identities by certain of their contingent properties. What we discover when we discover a theoretical identity is the underlying nature of the kind that we identify by those contingent properties. Now, of course, it was being a posteriori, not being contingent, that mattered to the identity theorists anyway, so the necessity of identity is not, in itself, damaging to mind brain identity theories. However, Kripke also argued persuasively that the alleged mind brain identities could not be treated in the same way as ordinary theoretical identities. We "identify" pain by feeling it, and surely how it feels is an essential property of pain, not a contingent property. Thus, a mind body identity theory must provide a different explanation of why its identities are a posteriori. A new wave of materialists has appeared on the scene with a new strategy for explaining [1] the a posteriori nature of its alleged identities. The strategy is to locate the explanation for the a posteriori nature of mind body identities, not on the side of the world, but on the side of the mind -in different ways of thinking about or imagining, or in different concepts. Thus, on this new view, there is only one property—this brain process type, which is identical with this pain..

I argue for three principle claims. First, philosophers who seek to integrate the semantic and the intentional into a naturalistic metaphysical worldview need to address a task that they have thus far largely failed even to notice: explaining into- level connections between the physical and the intentional in a naturalistically acceptable way. Second, there are serious reasons to think that this task cannot be carried out in a way that would vindicate realism about intentionality. Third, there is much to be said for an irrealist, non-eliminativist, naturalistic approach to intentionality that I call "preservative irrealism"

How does mind fit into nature? Philosophy has long been concerned with this question. No contemporary philosopher has done more to clarify it than Jaegwon Kim, a distinguished analytic philosopher specializing in metaphysics and philosophy of mind. With new contributions from an outstanding line-up of eminent scholars, this volume focuses on issues raised in Kim's work. The chapters cluster around two themes: first, exclusion, supervenience, and reduction, with attention to the causal exclusion argument for which Kim is widely celebrated; and second, phenomenal consciousness and qualia, with attention to the prospects for a functionalist account of the mental. This volume is sure to become a major focus of attention and research in the disciplines of metaphysics and philosophy of mind

Terry Horgan University of Memphis In this paper I address the problem of causal exclusion, specifically as it arises for mental properties (although the scope of the discussion is more general, being applicable to other kinds of putatively causal properties that are not identical to narrowly physical causal properties, i.e., causal properties posited by physics). I summarize my own current position on the matter, and I offer a defense of this position. I draw upon and synthesize relevant discussions in various <blockquote> [1] </blockquote> other papers of mine (some collaborative) that bear on this topic

In this critical study I first summarize Crispin Wright's "Truth and Objectivity". Wright maintains (1) that truth- aptness of a given discourse is neutral about questions of realism and anti- realism concerning the discourse, but also (2) that such metaphysical questions largely turn on discourse- specific constraints governing the truth- predicate. I urge a distinction between (i) Wright's general approach to truth and objectivity, and (ii) his apparent inclination to implement and the approach by construing truth as a fundamentally epistemic notion. I argue against an epistemically reductive implementation, and I briefly sketch an alternative way to implement the book's core ideas

I distinguish two broad approaches to vagueness that I call "robust" and "wimpy". Wimpy construals explain vagueness as robust (i.e., does not manifest arbitrary precision); that standard approaches to vagueness, like supervaluationism or appeals to degrees of truth, wrongly treat vagueness as wimpy; that vagueness harbors an underlying logical incoherence; that vagueness in the world is therefore impossible; and that the kind of logical incoherence nascent in vague terms and concepts is benign rather than malignant. I describe some implications for logic, semantics, and metaphysics

David Marr provided an influential account of levels of description in classical cognitive science. In this paper we contrast Marr'ent with some alternatives that are suggested by the recent emergence of connectionism. Marr's account is interesting and important both because of the levels of description it distinguishes, and because of the way his presentation reflects some of the most basic, foundational, assumptions of classical AI-style cognitive science. Thus, by focusing on levels of description, one can sharpen foundational differences between classicism and potential non-classical conceptions of mentality that might emerge under the rubric of connectionism.
