Mind-Brain Identity Theory

Flat Physicalism is a theory of through and through type reductive physicalism, understood in light of recent results in the conceptual foundations of physics. In Flat Physicalism, as in physics, so-called "high level" concepts and laws are nothing but partial descriptions of the complete states of affairs of the universe. "Flat physicalism" generalizes this idea, to form a reductive picture in which there is no room for levels, neither explanatory nor ontological. The paper explains how phenomena that seem to be (...) cases of multiple realization of special sciences kinds by physical kinds are fully explains in a reductive physicalist way. Finally, the paper exemplifies the fruitfulness of this reductive approach by showing how it can account even for a case of high-level anomaly in a deterministic universe (for example anomaly of the mental, should this turn our to be a fact about the world) - a result that may be called Anomalous Physicalism.

This thesis explores the possibility of theoretically conceiving consciousness as an activity of the brain. Objections, based on the concept of qualia, to the identification of consciousness with a brain activity are refuted. Phenomenal consciousness is identified with access-consciousness. Consciousness is conceived as a higher order processing of informational states of the brain. The state of consciousness represents an integration of prior nonconscious states. Libet’s research on the timing of conscious experience is reviewed and analyzed. His hypothesis of backward referral (...) is rejected. Since specific brain activity (the readiness potential) precedes the conscious intention, the implications of this fact on the concepts of volition and free will are discussed. Non-deliberate voluntary acts are performed without a prior consciousness of the intention to perform them. Conversely, the decision to perform a deliberate act is influenced by consciousness of the intention. Free will is viewed as compatible with the causal determination of mental processes. The theory is successfully applied to the different contents of consciousness: consciousness of perceptions, of bodily sensations, of actions, of memories, of ideas, of thoughts, of language, of affective states, of beliefs, of desires, of oneself and consciousness of being conscious. The relation between the theory of consciousness and psychoanalysis is also explored. Psychoanalysis is seen as compatible with the proposed theory, which is able to enlighten some aspects of the process of becoming conscious in psychoanalytic treatment. The general approach is interdisciplinary : the theory must take into account constraints derived from philosophy, neurophysiology, psychology, neuropsychology, etc. Consciousness is conceived, not as a property of some mental states, but as a specific higher-order activity, based on lower-order nonconscious activities.

I explore the possibility that mentality can be characterized as a level in between the functional and the neurological, namely as a physical system exhibiting a specific kind of chaos. The argument is meant to make a case for this kind of characterization rather than giving one in specific detail.

Reductionists say things like: all mental properties are physical properties; all normative properties are natural properties. I argue that the only way to resist reductionism is to deny that causation is difference making (thus making the epistemology of causation a mystery) or to deny that properties are individuated by their causal powers (thus making properties a mystery). That is to say, unless one is happy to deny supervenience, or to trivialize the debate over reductionism. To show this, I argue that (...) if properties are individuated by their causal powers then, surprisingly, properties are individuated by necessary co-exemplification. (shrink)

In this paper I argue that a priori arguments fail to present any real problem for physicalism. They beg the question against physicalism in the sense that the argument will only seem compelling if one is already assuming that qualitative properties are nonphysical. To show this I will present the reverse-zombie and reverse-knowledge arguments. The only evidence against physicalism is a priori arguments, but there are also a priori arguments against dualism of exactly the same variety. Each of these parity (...) arguments has premises that are just as intuitively plausible, and it cannot be the case that both the traditional scenarios and the reverse-scenarios are all ideally conceivable. Given this one set must be merely prima facie conceivable and only empirical methods will tell us which is which. So, by the time a priori methodology will be of any use it will be too late.

The materialist version of the mind/brain identity theory has met with considerable challenges from philosophers of mind. The author first dispenses with a popular objection to the theory based on the law of indiscernibility of identicals. By means of discussing the vexatious problem of phenomenal qualities, he explores how the debate may be advanced by seeing each dualist and monist ontology through the lens of an evolutionary epistemology. The author suggests that by regarding each ontology as the core of a (...) scientific research programme, each of these logically irrefutable hypotheses can be tested rationally. (shrink)

To seek an answer to the question “What is the origin of consciousness?” one must first assume a perspective within the most fundamental ontological questions in philosophy. These questions include: What is ultimate reality? Is it ultimately one thing (monism, say, matter or spirit), two things (dualism, say, matter and spirit or mind), or many things? Is it timeless and unchanging or a process of continual change? Is the universe God-created, self-created, or perhaps an accident?

The Warner Books back cover proclaims: In the tradition of Oliver Sachʼs [sic] bestselling *The Man Who Mistook His Wife for a Hat...* The manner and misspellingsignify that Cytowic himself had nothing to do with such publishing hucksterism. However, one thing is clear upon reading this book: Richard Cytowic, M.D., is no Oliver Sacks. Though, as will be seen, there is much in here to recommend itself, his stilted reproduction of conversations which or may not have taken place and his (...) CreativeFiction 100 characterizations (i.e., Dr. Wood's continual inhalation of smoke or food) strike the experienced reader as painfully contrived, as though Cytowic were doing hislevel best to imitate Sacks and reach that always-elusive wider audience.

This paper employs a case study from the history of neuroscience—brain reward function—to scrutinize the inductive argument for the so-called ‘Heuristic Identity Theory’ (HIT). The case fails to support HIT, illustrating why other case studies previously thought to provide empirical support for HIT also fold under scrutiny. After distinguishing two different ways of understanding the types of identity claims presupposed by HIT and considering other conceptual problems, we conclude that HIT is not an alternative to the traditional identity theory so (...) much as a relabeling of previously discussed strategies for mechanistic discovery.

THE MIND-BODY PROBLEM: A GUIDE TO THE CURRENT DEBATE (EDITED BY RICHARD WARNER AND TA D E U S Z SZUBKA) contains recent essays by the key players in the the field of the Mind-Body problem: Searle, Fodor, Problem Honderich, Nagel, McGinn, Stich, Rorty and others. But there are a few interesting exceptions, for example Edelman, Popper, Putnam and Dennett. Nevertheless, these thinkers do get a mention here and there, and nearly all the exciting topical issues are dealt with, including (...) externalism, functionalism, intentionality, Turing computational models, and the relationship between these philosophical problems and psychology. I am particularly struck by the tendency to engage in an evasive stratagem when it comes to stating the physicalist thesis. Instead of a clear definitive position about what kind of physical science would achieve the hoped-for reduction, what I found was variations on Lewis's claim that the reduction would be effected by a "unified body of scientific theories of the sort we now accept". Materialism used to be a clear doctrine: a clockwork Universe of impenetrable particles. But materialism transcended itself. First through Hobbes' and Leibniz's criticisms of Descartes, then Newton's demolition of the Cartesian idea that matter was essentially extension by introducing gravity (action at a distance) and then through the field theories of Faraday and Maxwell, and more recently through Einstein's work, which undermined the "substance" view of matter, something that remained permanent while other changes occurred. I contrast the perspectives of the Churchlands with those of Donald T. Campbell, Karl Popper and other evolutionary and emergentist views. -/- . (shrink)

The identity theory of mind is advocated and developed by different philosophers beginning with Place, Feigl and Smart. The main thesis of this theory is – states and processes of the mind are identical to states and processes of the brain. Although this theory is better than dualism and Behaviourism, still it has its own problems. This theory leaves many things unexplained with regard to the relation between mind and body, which have been questioned by different thinkers in different periods. (...) Hence, in this article I am going to find out only the problem of identity in the ‘Identity theory of mind’. (shrink)

Is it rational to believe that the mind is identical to the brain? Identity theorists say it is (or looks like it will be, once all the neuroscientific evidence is in), and they base this claim on a general epistemic route to belief in identity. I re-develop this general route and defend it against some objections. Then I discuss how rational belief in mind–brain identity, obtained via this route, can be threatened by an appropriately adjusted version of the anti-physicalist knowledge (...) argument. Responses to this threat usually appeal either to different modes of presentation or to phenomenal concepts. But neither type of response is satisfactory. I provide a novel response, which appeals to an innocuous epistemic peculiarity of phenomenal states, namely their, as I shall call it, evidential insulation. (shrink)

This collection of articles was written over the last 10 years and the most important and longest within the last year. Also I have edited them to bring them up to date (2017). The copyright page has the date of this first edition and new editions will be noted there as I edit old articles or add new ones. All the articles are about human behavior (as are all articles by anyone about anything), and so about the limitations of having (...) a recent monkey ancestry (8 million years or much less depending on viewpoint) and manifest words and deeds within the framework of our innate psychology as presented in the table of intentionality. As famous evolutionist Richard Leakey says, it is critical to keep in mind not that we evolved from apes, but that in every important way, we are apes. If everyone was given a real understanding of this (i.e., human ecology and psychology) in school, maybe civilization would have a chance. In my view these articles and reviews have many novel and highly useful elements, in that they use my own version of the recently (ca. 1980’s) developed dual systems view of our brain and behavior to lay out a logical system of rationality (personality, psychology, mind, language, behavior, thought, reasoning, reality etc.) that is sorely lacking in the behavioral sciences (psychology, philosophy, literature, politics, anthropology, history, economics, sociology etc.). -/- The philosophy centers around the two writers I have found the most important, Ludwig Wittgenstein and John Searle, whose ideas I combine and extend within the dual system (two systems of thought) framework that has proven so useful in recent thinking and reasoning research. As I note, there is in my view essentially complete overlap between philosophy, in the strict sense of the enduring questions that concern the academic discipline, and the descriptive psychology of higher order thought (behavior). Once one has grasped Wittgenstein’s insight that there is only the issue of how the language game is to be played, one determines the Conditions of Satisfaction (what makes a statement true or satisfied etc.) and that is the end of the discussion. Now that I think I understand how the games work I have mostly lost interest in philosophy, which of course is how Wittgenstein said it should be. But since they are the result of our innate psychology, or as Wittgenstein put, it due to the lack of perspicuity of language, the problems run throughout all human discourse, so there is endless need for philosophical analysis, not only in the ‘human sciences’ of philosophy, sociology, anthropology, political science, psychology, history, literature, religion, etc., but in the ‘hard sciences’ of physics, mathematics, and biology. It is universal to mix the language game questions with the real scientific ones as to what the empirical facts are. Scientism is ever present and the master has laid it before us long ago, i.e., Wittgenstein (hereafter W) beginning principally with the Blue and Brown Books in the early 1930’s. -/- "Philosophers constantly see the method of science before their eyes and are irresistibly tempted to ask and answer questions in the way science does. This tendency is the real source of metaphysics and leads the philosopher into complete darkness." (BBB p18) -/- Nevertheless, a real understanding of Wittgenstein’s work, and hence of how our psychology functions, is only beginning to spread in the second decade of the 21st century, due especially to P.M.S. Hacker (hereafter H) and Daniele Moyal-Sharrock (hereafter DMS), but also to many others, some of the more prominent of whom I mention in the articles. -/- When I read ‘On Certainty’ a few years ago I characterized it in an Amazon review as the Foundation Stone of Philosophy and Psychology and the most basic document for understanding behavior, and about the same time DMS was writing articles noting that it had solved the millennia old epistemological problem of how we can know anything for certain. I realized that W was the first one to grasp what is now characterized as the two systems or dual systems of thought, and I generated a dual systems (S1 and S2) terminology which I found to be very powerful in describing behavior. I took the small table that John Searle (hereafter S) had been using, expanded it greatly, and found later that it integrated perfectly with the framework being used by various current workers in thinking and reasoning research. -/- Since they were published individually, I have tried to make the book reviews and articles stand by themselves, insofar as possible, and this accounts for the repetition of various sections, notably the table and its explanation. I start with a short article that presents the table of intentionality and briefly describes its terminology and background. Next, is by far the longest article, which attempts a survey of the work of W and S as it relates to the table and so to an understanding or description (not explanation as W insisted) of behavior. -/- The key to everything about us is biology, and it is obliviousness to it that leads millions of smart educated people like Obama, Chomsky, Clinton and the Pope to espouse suicidal utopian ideals that inexorably lead straight to Hell On Earth. As W noted, it is what is always before our eyes that is the hardest to see. We live in the world of conscious deliberative linguistic System 2, but it is unconscious, automatic reflexive System 1 that rules. This is Searle’s The Phenomenological Illusion (TPI), Pinker’s Blank Slate and Tooby and Cosmides Standard Social Science Model. Democracy and equality are wonderful ideals, but without strict controls, selfishness and stupidity gain the upper hand and soon destroy any nation and any world that adopts them. The monkey mind steeply discounts the future, and so we sell our children’s heritage for temporary comforts. Thus I end with an essay on the great tragedy playing out in America and the world, which can be seen as a direct result of TPI. The astute may wonder why we cannot see System 1 at work, but it is clearly counterproductive for an animal to be thinking about or second guessing every action, and in any case there is no time for the slow, massively integrated System 2 to be involved in the constant stream of split second ‘decisions’ we must make. As W noted, our ‘thoughts’ (T1 or the thoughts of System 1) must lead directly to actions. -/- It is my contention that the table of intentionality (rationality, mind, thought, language, personality etc.) that features prominently here describes more or less accurately, or at least serves an heuristic for, how we think and behave, and so it encompasses not merely philosophy and psychology but everything else (history, literature, mathematics, politics etc.). Note especially that intentionality and rationality as I (along with Searle, Wittgenstein and others) view it, includes both conscious deliberative System 2 and unconscious automated System 1 actions or reflexes. -/- Thus all the articles, like all behavior, are intimately connected if one knows how to look at them. As I note, The Phenomenological Illusion (oblivion to our automated System 1) is universal and extends not merely throughout philosophy but throughout life. I am sure that Chomsky, Obama, Zuckerberg and the Pope would be incredulous if told that they suffer from the same problem as Hegel, Husserl and Heidegger, but it’s clearly true. While the phenomenologists only wasted a lot of people’s time, they are wasting the earth. (shrink)

Carl Gillett has defended what he calls the “dimensioned” view of the realization relation, which he contrasts with the traditional “flat” view of realization (2003, 2007; see also Gillett 2002). Intuitively, the dimensioned approach characterizes realization in terms of composition whereas the flat approach views realization in terms of occupiers of functional roles. Elsewhere we have argued that the general view of realization and multiple realization that Gillett advances is not able to discharge the theoretical duties of those relations (Shapiro (...) 2004, unpublished manuscript; Polger 2004, 2007, forthcoming). Here we focus on an internal objection to Gillett’s account and then raise some broader reasons to reject it. (shrink)

A model of human consciousness is presented here in terms of physics and electronics using Upanishadic awareness. The form of Atman proposed in the Upanishads in relation to human consciousness as oscillating psychic energy-presence and its virtual or unreal energy reflection maya, responsible for mental energy and mental time-space are discussed. Analogy with Fresnel’s bi-prism experimental set up in physical optics is used to state, describe and understand the form, structure and function of Atman and maya, the ingredients of human (...) consciousness. A description of phases of mind in terms of conscious states and transformation of mental energy is given. Four states of consciousness and four modes of language communication and understanding processes are also given. Implications of above scientific awareness of Upanishadic wisdom to the modern scientific fields of physiological psychology, cognitive sciences, mind-machine modeling and natural language comprehension are suggested. -/- .

``People say again and again that philosophy doesn´t really progress, that we are still occupied with the same philosophical problems as were the Greeks. But the people who say this don´t understand why is has to be so. It is because our language has remained the same and keeps seducing us into asking the same questions. As long as there continues to be a verb´to be´that looks as if it functions in the same way as´to eatánd´to drink´, as long as (...) we still have the adjectives´identical´,´true´,´false´,´possible´, as long as we continue to talk of a river of time, of an expanse of space, etc., etc., people will keep stumbling over the same puzzling difficulties and find themselves staring at something which no explanation seems capable of clearing up. And what´s more, this satisfies a longing for the transcendent, because, insofar as people think they can seèthe limits of human understanding´, they believe of course that they can see beyond these.`` ´ This quote is from Ludwig Wittgenstein who redefined philosophy some 70 years ago (but most people have yet to find this out). Dennett, though he has been a philosopher for some 40 years, is one them. It is also curious that both he and his prime antagonist, John Searle, studied under famous Wittgensteinians (Searle with John Austin, Dennett with Gilbert Ryle) but Searle got the point and Dennett did not. Dennett is a hard determinist (though he trys to sneak reality in the back door), and perhaps this is due to Ryle, whose famous book´The Concept of Mind´(1949) continues to be reprinted. That book did a great job of exorcising the ghost but it left the machine. Dennett enjoys making the mistakes Wittgenstein, Ryle (and many others since) have exposed in detail. Our use of the words consciousness, choice, freedom, intention, particle, thinking, determines, wave, cause, happened, event(and so on endlessly) are rarely a source of confusion but as soon as we leave normal life and enter philosophy(and any discussion detached from the environment in which language evolved) chaos reigns. Like most Dennet lacks a coherent framework-which Searle has called the logical structure of rationality. I have expanded on this considerably since I wrote this review and my recent articles show in detail what is wrong with Dennet's approach to philosophy. Let me end with another quote from Wittgenstein--´Ambition is the death of thought´. -/- Those wishing a comprehensive up to date account of Wittgenstein, Searle and their analysis of behavior from the modern two systems view may consult my article The Logical Structure of Philosophy, Psychology, Mind and Language as Revealed in Wittgenstein and Searle (2016).

In this article I explore a number of questions that have not been adequately investigated in philosophy of mind circles: are minds located in the same place as the brains (or other computing machinery) supporting them? Must they exist at the same location as the body? Must they exist at the same time? Could a single mind be implemented in multiple brains, or multiple minds in a single brain? Under what conditions might a single mind persist despite being implemented successively (...) in different brains? What contributions do features of the computing machinery make to these questions, compared to the contribution made by the body and embedded point of view? Some of these questions have been touched on previously, but there hasn’t been any attempt at a systematic analysis of the various consequences that different approaches in the philosophy of mind have for how the spatiotemporal location, synchronic individuation and diachronic identity of minds relates to the spatiotemporal location, synchronic individuation, and diachronic identity of both the implementing computational machinery and the embodied embedded point of view. I make a first stab at such an analysis by discussing a variety of thought experiments in which such questions of location, individuation, and identity arise, and I explore how various approaches to understanding the mind – identity theoretic, functionalist, contentualist, embodied/embedded/extended, and so forth – would respond to such situations. A number of novel issues emerge, and some surprising affinities are revealed. (shrink)

The subject of zombies is one of the most discussed and controversial topics of philosophy of mind. In this paper I will first examine the main argument of zombies, providing a summary of the current discussion. Then I will introduce a thought experiment, an epistemic window on a metaphysical scenario. By the thought experiment I will argue that zombies are logically impossible. Further I will discuss another recent epistemic window. Finally I will provide some other logical consideration to prove that (...) intentionality is not reducible to the cognitive functional aspects of the mind and that, moreover, the subjective recognition of semantic contents is necessary in order to consider as sensical the verbal behavior of a zombie.

The Phenomenal Concept Strategy offers the physicalist perhaps the most promising means of explaining why the connection between mental facts and physical facts appears to be contingent even though it is not. In this article, we show that the large body of evidence suggesting that our concepts are often embodied and grounded in sensorimotor systems speaks against standard forms of the PCS. We argue, nevertheless, that it is possible to formulate a novel version of the PCS that is thoroughly in (...) keeping with embodied cognition, focuses on features of physical concepts, and succeeds in explaining the appearance of contingency.

I endorse a 12-word metaphysics. [1] Stoff ist Kraft ≈ being is energy. [2] Wesen ist Werden ≈ being is becoming. [3] Sein ist Sosein ≈ being is qualit[ativit]y. [4] Ansichsein ist Fürsichsein ≈ being is mind. [1]–[3] are plausible metaphysical principles and unprejudiced consideration of what we know about concrete reality obliges us to favor [4], i.e. panpsychism or panexperientialism, above all other positive substantive proposals. For [i] panpsychism is the most ontologically parsimonious view, given that the existence of (...) conscious experience is certain and that panpsychism doesn’t posit the existence of any kind of stuff other than conscious experience. [ii] A question also arises about why metaphysicians have posited the existence of something for which there is zero evidence: non-experiential concrete reality. The question is the more pressing because of the silence of physics: physics with its numbers and equations is perfectly silent on the question of the intrinsic non-structural nature of reality.

Functionalism is often used to identify mental states with physical states. A particularly powerful case is Lewis's analytical functionalism. Kripke's view seriously challenges any such identification. The dispute between Kripke and Lewis's views boils down to whether the term ‘pain’ is rigid or nonrigid. It is a strong intuition of ours that if it feels like pain it is pain, and vice versa, so that ‘pain’ should designate, with respect to every possible world, all and only states felt as pain. (...) Hence, in order to settle the dispute, we need to check which of the two – Kripke's use of ‘pain’ as rigid, or Lewis's use of ‘pain’ as nonrigid – better meets this intuition. I show that, despite crucial differences in both their semantic and metaphysical assumptions, surprisingly, both views meet this intuition equally well. Thus it appears that this question of rigidity cannot, in principle, be solved, and so, at least with respect to this particular dispute, the jury is still out on whether mental states are identical to physical states.

The mind-brain identity theory, the thesis that sensations are identical with properties or processes of the brain, was introduced into contemporary discussion by U.T. Place, Herbert Feigl, and J.J.C Smart in the 1950s. Despite its widespread rejection in the following decades, the identity theory has received several carefully articulated defenses in recent years. Aside from developing novel responses to well-known arguments against the identity theory, contemporary identity theorists have argued that the epistemological resources available to support the adoption of identities (...) are more plentiful than has often been supposed; further, they have argued that mind-brain identities allow for the resolution of otherwise intractable explanatory puzzles about the phenomenal properties of experience. From an epistemological perspective, identity theorists have thus argued that a central reason for believing theoretical identities—both mind-brain identities as well as more mundane identities such as water = H2O—stems from the explanatory power that they confer. Yet from an explanatory perspective, identity theorists have maintained that identities cannot themselves be explained; indeed, they have maintained that it is hardly intelligible to request an explanation for an identity. This paper considers these ideas draws out an important tension between them. The central claim is that insofar as identity theorists insist on the explanatorily efficacy of identities, they should concede that there is a good sense in which theoretical identities can be explained. However, it is moreover argued that this concession is not especially problematic and, indeed, ought to be welcomed by identity theorists. (shrink)

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)

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. Opposing (...) 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.

Functionalism of robot pain claims that what is definitive of robot pain is functional role, defined as the causal relations pain has to noxious stimuli, behavior and other subjective states. Here, I propose that the only way to theorize role-functionalism of robot pain is in terms of type-identity theory. I argue that what makes a state pain for a neuro-robot at a time is the functional role it has in the robot at the time, and this state is type identical (...) to a specific circuit state. Support from an experimental study shows that if the neural network that controls a robot includes a specific 'emotion circuit', physical damage to the robot will cause the disposition to avoid movement, thereby enhancing fitness, compared to robots without the circuit. Thus, pain for a robot at a time is type identical to a specific circuit state. (shrink)

What is the relationship between pain and the body? I claim that pain is best explained as a type of personal experience and the bodily response during pain is best explained in terms of a type of mechanical neurophysiologic operation. I apply the radical philosophy of identity theory from philosophy of mind to the relationship between the personal experience of pain and specific neurophysiologic mechanism and argue that the relationship between them is best explained as one of type identity. Specifically, (...) pain is a specific type of personal experience identical to a specific type of allostatic stress response comprised of interdependent nervous, endocrine and immune mechanical operations.

This work examines and critically evaluates the proposal that phenomenal properties, or the subjective qualities of experience, present a formidable challenge for the mind-body identity theory. Physicalism per se is construed as being ontically committed only to phenomena which can be made epistemically and cognitively available in the third person; observed and understood from within an objective frame of reference. Further, the identity relation between the mental and the physical is taken to be strict identity; the mental phenomena in question (...) just are the physical phenomena on which, ex hypothesi, they supervene. The problem of phenomenal properties has two basic strands. The first is the problem of how they are causally related to the physical; if they are not physical phenomena, by what causal mechanism might they be related to physical phenomena? One of the motivating considerations which led to the identity thesis was that it appeared to remove this problem. Our interest, however, is in evaluating the arguments which purport to establish that phenomenal properties are, indeed, distinct from the physical. (shrink)

In this essay I shall argue that the crucial assumptions of Kripke's argument, i.e. the collapse of the appearance/reality distinction in the case of phenomenal states and the idea of a qualitatively identical epistemic situation, imply an objective principle of identity for mental-state types. This principle, I shall argue, rather than being at odds with physicalism, is actually compatible with both the type-identity theory of the mind and Kripke's semantics and metaphysics. Finally, I shall sketch a version of the type-identity (...) theory. (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.

The identity theory’s rise to prominence in analytic philosophy of mind during the late 1950s and early 1960s is widely seen as a watershed in the development of physicalism, in the sense that whereas logical behaviourism proposed analytic and a priori ascertainable identities between the meanings of mental and physical-behavioural concepts, the identity theory proposed synthetic and a posteriori knowable identities between mental and physical properties. While this watershed does exist, the standard account of it is misleading, as it is (...) founded in erroneous intensional misreadings of the logical positivists’—especially Carnap’s—extensional notions of translation and meaning, as well as misinterpretations of the positivists’ shift from the strong thesis of translation-physicalism to the weaker and more liberal notion of reduction-physicalism that occurred in the Unity of Science programme. After setting the historical record straight, the essay traces the first truly modern identity theory to Schlick’s pre-positivist views circa 1920 and goes on to explore its further development in Feigl, arguing that the fundamental difference between the Schlick-Feigl identity theory and the more familiar and influential Place-Smart-Armstrong identity theory has resurfaced in the deep and seemingly unbridgeable gulf in contemporary philosophy of consciousness between inflationary mentalism and deflationary physicalism.

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. If properly framed, this schema suits also for the type identity theory of mind. Some consequences of this point are evaluated.

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)

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)
