Terry Horgan has made impressive and highly important contributions to numerous fields of philosophy ? metaphysics, philosophy of mind and psychology, philosophy of language, philosophy of science, and value theory, to mention the most prominent ones. What gives Horgan's work a powerful and clarifying unity is his deep and unflagging commitment to philosophical naturalism. In fact, Horgan himself has often invoked naturalism to motivate his positions and arguments on a number of philosophical issues. In this talk, I will discuss some (...) questions concerning Horgan's naturalism and his philosophy of mind.Among them are such questions as these: What exactly is the naturalism that drives Horgan's philosophical thinking? Is it a reasonable and plausible form of naturalism? Exactly how does his naturalism lead to the conclusions and arguments he defends? Should "proper" naturalists follow Horgan's lead? I will discuss these questions in relation to Horgan's work on mind-body supervenience, the autonomy of psychological explanation, reductionism, mental causation, and related issues. (shrink)

In recent decades, a view of identity I call Sortalism has gained popularity. According to this view, if a is identical to b, then there is some sortal S such that a is the same S as b. Sortalism has typically been discussed with respect to the identity of objects. I argue that the motivations for Sortalism about object-identity apply equally well to event-identity. But Sortalism about event-identity poses a serious threat to the view that mental events are token identical (...) to physical events: A particular mental event m is identical with a particular physical event p only if there is a sortal S such that m and p are both Ss. If there is no such sortal, the doctrine of token-identity is not true. I argue here that we have no good reason for thinking that there is any such sortal. (shrink)

As part of his ongoing critique of metaphysical realism, Hilary Putnam has recently argued that current materialist theories of mind that locate mental phenomena in the brain can make no sense of the proposed identifications of mental states with physical (or physical cum computational) states, or of the supervenience of mental properties with physical properties. The aim of this paper is to undermine Putnam's objections and reassert the intelligibility – and perhaps the plausibility – of some form of mind-body identity (...) and supervenience. (shrink)

The analysis of mental concepts suggests that the distinctionbetween the mental and the nonmental is not ontologically fundamental,and that, whereas mental processes are one and the same things as thebrain processes with which they are correlated, dispositional mentalstates depend causally on and are, thus, ''''distinct existences'''' fromthe states of the brain microstructure with which ''they'' are correlated.It is argued that this difference in the relation between an entity andits composition/underlying structure applies across the board. allstuffs and processes are the same (...) thing as is described by a descriptionof their microstructure. In all cases where the manifestation of adisposition extends beyond the ''''skin'''' of the dispositional propertybearer, dispositions invariably depend causally on the structure,usually the microstructure, of the bearer.

1. Consider the basic outlines of the mind-body debate as it is found in contemporary Anglo-American analytic philosophy. The central question is “whether mental phenomena are physical phenomena, and if not, how they relate to physical phenomena.”1 Over the centuries, a wide range of possible solutions to this problem have emerged. These are the various “isms” familiar to any student of the debate: Cartesian dualism, idealism, epiphenomenalism, central state materialism, non- reductive physicalism, anomalous monism, and so forth. Each purports to (...) specify, among other things, the metaphysical relationship between the mental and the physical. They do so by specifying whether, or in what way, mental entities are identical to, reducible to, realized by, supervenient upon, or in causal interaction with physical entities. Thus, a convenient way to survey the range of positions is to enter them in a table (see Table 1). Rows correspond to the major kinds of metaphysical relation which might obtain between mental and physical entities. Each columns corresponds to one of the generic positions available in the debate. The particular theories defended by individual philosophers are usually just specific versions of generic positions. Thus Malebranche’s occasionalism is a version of causal dualism, distinguished by a peculiar account of the way in which causal interaction between mental and physical is actually effected. The central philosophical challenge is to determine which of these positions correctly describes the mental/physical relationship. Positions are evaluated for internal consistency, their fit with “intuitions,” their compatibility with scientific developments, and so forth. The mind-body debate, in this simple form, is set out in any number of.. (shrink)
