In this article, I undertake the tasks: (i) of reconsidering Feigl’s notion of a ‘nomological dangler’ in light of recent discussion about the viability of accommodating phenomenal properties, or qualia, within a physicalist picture of reality; and (ii) of constructing an argument to the effect that nomological danglers, including the way qualia are understood to be related to brain states by contemporary dualists, are extremely unlikely. I offer a probabilistic argument to the effect that merely nomological danglers are extremely unlikely, (...) the only probabilistically coherent candidates being ‘anomic danglers’ (not even nomically correlated) and ‘necessary danglers’ (more than merely nomically correlated). After I show, based on similar probabilistic reasoning, that the first disjunct (anomic danglers) is very unlikely, I conclude that the identity thesis is the only remaining candidate for the mental–physical connection. The novelty of the argument is that it brings probabilistic considerations in favor of physicalism, a move that has been neglected in the recent burgeoning literature on the subject. (shrink)

A philosophy might take its general inspiration from (1) commonsense; (2) careful observation; (3) philosophical argumentation; (4) the sciences; (5) "higher" sources of illumination. It is argued in this paper that it is bedrock commonsense, and the sciences, which are the most reliable foundations for a philosophy. This result is applied to the discussion and defense of a materialist theory of the mind.

It is argued that, because of scientific essentialism, two currently popular arguments against the mind-body identity thesis -- the multiple-realizability argument and the Nagel-Jackson knowledge argument -- are unsatisfactory as they stand and that their problems are incurable. It is then argued that a refutation of the identity thesis in its full generality can be achieved by weaving together two traditional Cartesian arguments -- the modal argument and the certainty argument. This argument establishes, not just the falsity of the identity (...) thesis, but also the metaphysical possibility of disembodiment. (shrink)

Functionalists in philosophy of mind traditionally raise two major arguments against the type identity theory: (1) psychological states are _multiply realizable_ so that there are no one-to-one mappings of psychological states onto neural states and (2) the most that evidence could ever establish is the _correlation_ of psychological and neural states, not their identity. We defend a variant on the traditional type identity theory which we call _heuristic identity theory_ (HIT) against both of these objections. Drawing its inspiration from scientific (...) practice, heuristic identity theory construes identity claims as hypotheses that guide subsequent inquiry, not as conclusions of the research. (shrink)

We make how a person acts intelligible by revealing it as rational in the light of what she perceives, thinks, wants and so on. For example, we might explain that she reached out and picked up a glass because she was thirsty and saw that it contained water. In doing this, we are giving a causal explanation of her behaviour in terms of her antecedent beliefs, desires and other attitudes. Her wanting a drink and realizing that the glass contained one (...) caused her reaching out and grasping for it. This tells us how the action came about and makes sense of why it happened. At least, something broadly along these lines strikes me as a fairly crude and partial regimentation of our pretheoretic understanding of everyday action explanation. (shrink)

This paper disputes a common definition of token identity theory. It also observes that within the philosophical literature there are two significantly different definitions of token identity theory that are commonly used.

Content externalism is the dominant view in the philosophy of mind. Content essentialism, the thesis that thought tokens have their contents essentially, is also popular. And many externalists are supporters of such essentialism. However, endorsing the conjunction of those views either (i) commits one to a counterintuitive view of the underlying physical nature of thought tokens or (ii) commits one to a slightly different but still counterintuitive view of the relation of thought tokens to physical tokens as well as a (...) rejection of realist physicalism. In this essay I reveal the problem and articulate and adjudicate among the possible solutions. I will end up rejecting content essentialism. (shrink)

Orthodox neural materialists think mental states are neural events or orthodox material properties of neutral events. Orthodox material properties are defining properties of the “physical”. A “defining property” of the physical is a type of property that provides a necessary condition for something’s being correctly termed “physical”. In this paper I give an argument against orthodox neural materialism. If successful, the argument would show at least some properties of some mental states are not orthodox material properties of neural events. Oppositing (...) philosophical orthodoxy, I show there are no posteriori identities -- identities that cannot be known of a priori. (shrink)

In recent years Jaegwon Kim has offered an argument – the ‘supervenience argument’ – to show that supervenient mental properties, construed as second- order properties distinct from their first-order realizers, do not have causal powers of their own. In response, several philosophers have argued that if Kim’s argument is sound, it generalizes in such a way as to condemn to causal impotency all properties above the level of basic physics. This paper discusses Kim’s supervenience argument in the context of his (...) reply to this so-called ‘generalization argument’. In particular, the paper focuses on the level/order distinction, to which Kim appeals in his reply to the generalization argument, and on the relation between this distinction and two varieties of functionalism, ‘realizer’ vs. ‘role’ functionalism. The author argues that a proper analysis of the notions of levels and orders undermines Kim’s response to the generalization argument, and suggests that Kim’s reductionist strategy for vindicating the causal powers of mental properties is better served if mental properties are construed as first-order properties, as realizer-functionalism recommends.

In this paper it is argued that the multiple realizability argument and Kripke's argument are based on schemas of identifications rather than identification. In fact, "heat = molecular motion" includes a term "molecular motion" that does not capture a natural kind, nor has a unique referent. Is properly framed, this schema suits also for the type identity theory of mind. Some consequences of this point are evaluated.

Two issues are raised with regard to Ted Honderich's A Theory of Determinism. First, regarding the relation between a token identity theory of mental and physical events and Honderich's ?psychoneural union theory?, it is suggested that a token identity theory would serve Honderich's purposes while securing a simpler ontology. Second, it is argued that there is a substantive philosophical issue dividing compatibilists and incompatibilists on the question of whether persons possess free will, contrary to Honderich's contention that the compatibilist and (...) incompatibilist differ only in responsive attitude.

The mind-body problem arises because all theories about mind-brain connections are too deeply obscure to gain general acceptance. This essay suggests a clear, simple, mind-brain solution that avoids all these perennial obscurities. (1) It does so, first of all, by reworking Strawson and Stoljar’s views. They argue that while minds differ from observable brains, minds can still be what brains are physically like behind the appearances created by our outer senses. This could avoid many obscurities. But to clearly do so, (...) it must first clear up its own deep obscurity about what brains are like behind appearances, and how they create the mind’s privacy, unity and qualia – all of which observable brains lack. (2) This can ultimately be done with a clear, simple assumption: our consciousness is the physical substance that certain brain events consist of beyond appearances. For example, the distinctive electrochemistry in nociceptor ion channels wholly consists of pain. This rejects that pain is a brain property: instead it’s a brain substance that occupies space in brains, and exerts forces by which it’s indirectly detectable via EEGs. (3) This assumption is justified because treating pains as physical substances avoids the perennial obscurities in mind-body theories. For example, this ‘clear physicalism’ avoids the obscure nonphysical pain of dualism and its spinoffs. Pain is instead an electrochemical substance. It isn’t private because it’s hidden in nonphysical minds, but instead because it’s just indirectly detected in the physical world in ways that leave its real nature hidden. (4) Clear physicalism also avoids puzzling reductions of private pains into more fundamental terms of observable brain activity. Instead pain is a hidden, private substance underlying this observable activity. Also, pain is fundamental in itself, for it’s what some brain activity fundamentally consists of. This also avoids reductive idealist claims that the world just exists in the mind. They yield obscure views on why we see a world that isn’t really out there. (5) Clear physicalism also avoids obscure claims that pain is information processing which is realizable in multiple hardwares (not just in electrochemistry). Molecular neuroscience now casts doubt on multiple realization. Also, it’s puzzling how abstract information gets ‘realized’ in brains and affects brains (compare ancient quandries on how universals get embodied in matter). A related idea is that of supervenient properties in nonreductive physicalism. They involve obscure overdetermination and emergent consciousness. Clear physicalism avoids all this. Pain isn’t an abstract property obscurely related to brains – it’s simply a substance in brains. (6) Clear physicalism also avoids problems in neuroscience. Neuroscience explains the mind’s unity in problematic ways using synchrony, attention, etc.. Clear physicalism explains unity in terms of intense neuroelectrical activity reaching continually along brain circuits as a conscious whole. This fits evidence that just highly active, highly connected circuits are fully conscious. Neuroscience also has problems explaining how qualia are actually encoded by brains, and how to get from these abstract codes to actual pain, fear, etc.. Clear physicalism explains qualia electrochemically, using growing evidence that both sensory and emotional qualia correlate with very specific electrical channels in neural receptors. Multiple-realization advocates overlook this important evidence. (7) Clear physicalism thus bridges the mind-brain gulf by showing how brains can possess the mind’s qualia, unity and privacy – and how minds can possess features of brain activity like occupying space and exerting forces. This unorthodox nonreductive physicalism may be where physicalism leads to when stripped of all its reductive and nonreductive obscurities. It offers a clear, simple mind-body solution by just filling in what neuroscience is silent about, namely, what brain matter is like behind perceptions of it. (shrink)

Kripke's argument against the identity theory in the philosophy of mind runs as follows. Suppose some psychophysical identity statement S is true. Then S would seem to be contingent at least in the sense that S seems possibly false. And given that seeming contingency entails genuine contingency when it comes to such statements S is contingent. But S is necessary if true. So S is false. This entry considers responses to each of the three premises. It turns out that each (...) response does not fully withstand scrutiny, and so Kripke's conclusion is hard to resist. Section 1 lays out Kripke's argument, and Sections 2 to 4 then discuss responses to each of the three premises respectively. (shrink)

I physicalism1 and the weak identity theory deny, while physicalism2 and the radical identity theory assert, that raw feels can be accomodated in a purely physicalistic framework. II A way of interpreting the claim of physicalism1 is that raw feels are emergents. III The doctrine of emergence asserts that: (i) there are different levels of existence, (ii) these levels of existence are distinguishable on the basis of the behaviour of entities of that level, and (iii) an adequate scientific explanation of (...) a lower level is inadequate for a higher level. IV The criteria of emergence are novelty and a priori unpredictability. V Either qualities or laws or both may be regarded as emergents. VI If the alleged impossibility of explaining higher level phenomena on the basis of explanation adequate for lower level phenomena is logical, then the impossibility is either trivial or it implies indeterminism. Consideration of theories of emergence: VII Semantic emergence. On this view emergence is theory-bound, analogous to indefinability or indemonstrability. VIII Methodological emergence. On this view what we regard as emergents depends on the theory we construct. IX Nomological emergence. On this view emergence is an empirical problem. Conclusion: if there are emergents, physicalism2 and the radical identity theory probably have to be abandoned. However, unless actual examples of emergents are produced both theories hold. The logical possibility of falsification is not an objection against physicalism2 and the radical identity theory; it is one of their merits. (shrink)

: The effects of head injury, even mild traumatic brain injury, are wide-ranging and profound. Persons with adult-onset head injury offer feminist philosophers important perspectives for philosophical methodology and philosophical research concerning personal identity, mind-body theories, and ethics. The needs of persons with head injury require the expansion of typical teaching strategies, and such adaptations appear beneficial to both disabled and non-disabled students.

How can we understand our human world, embedded as it is within the physical universe, in such a way that justice is done to both the richness, meaning and value of human life on the one hand, and what modern science tells us about the physical universe on the other hand? I argue that, in order to solve this problem, we need to see physics as being concerned only with a highly selected aspect of reality – that aspect which determines (...) how events unfold – the causally efficacious aspect. Physics cannot describe the experiential, and if it is extended so that it does so, physical theory would cease to be explanatory. The human world can, however, be understood in terms of a different kind of explanation, which I call “personalistic”. This is not reducible to physical explanation. The world is, in short, riddled with what may be called “double comprehensibility”. (shrink)

University Abstract Philosophers have sought to improve upon the logical empiricists’ model of scientific reduction. While opportunities for integration between the cognitive and the neural sciences have increased, most philosophers, appealing to the multiple realizability of mental states and the irreducibility of consciousness, object to psychoneural reduction. New Wave reductionists offer a continuum of comparative goodness of intertheoretic mapping for assessing reductions. Their insistence on a unified view of intertheoretic relations obscures epistemically significant crossscientific relations and engenders dismissive conclusions about (...) psychology. Richer, more sensitive accounts of explanatory pluralism and mechanistic explanation in science advocate multi-level approaches in cross-scientific settings and criticize the distance of the standard philosophical objections from working scientists’ practices and discoveries. The Heuristic Identity Theory, a new, scientifically informed version of the psycho-physical identity theory, incorporates these insights, showing how multiple realizability is an argument for (not against) identities in science and why, therefore, consciousness is not irreducible.

University and William Bechtel Washington University Abstract Explanatory pluralism holds that the sorts of comprehensive theoretical and ontological economies, which microreductionists and New Wave reductionists envision and which antireductionists fear, offer misleading views of both scientific practice and scientific progress. Both advocates and foes of employing reductionist strategies at the interface of psychology and neuroscience have overplayed the alleged economies that interlevel connections (including identities) justify while overlooking their fundamental role in promoting scientific research. A brief review of research on (...) visual processing provides support for the explanatory pluralist=s general model of cross-scientific relations and discloses the valuable heuristic role hypothetical identities play in cross-scientific research. That model also supplies grounds for hesitation about the correlation objection to the psycho-physical identity theory and complaints about an explanatory gap in physicalist accounts of consciousness. These takes on psycho-neural connections miss both the sorts of considerations that motivate hypothetical identities in science and their fundamental contribution to progressive research. Thus, their focus on the contributions of research at multiple levels of analysis does not bar explanatory pluralists from considering heuristic identity theory (HIT). Arguably, it encourages it.
