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)

Materialists say sensations and other kinds of mental states are physical events. Today, most materialists are neural materialists.

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’ Defining properties of the physical include spatial and temporal properties and causal propensities and sensitivities. A particle is an electron, for instance, by having a particular set of spatiotemporal properties and causal sensitivities and powers. (shrink)

In their recent book Philosophical Foundations of Neuroscience, Max Bennett and Peter Hacker attack neural materialism (NM), the view, roughly, that mental states (events, processes, etc.) are identical with neural states or material properties of neural states (events, processes, etc.). Specifically, in the penultimate chapter entitled “Reductionism,” they argue that NM is unintelligible, that “there is no sense to literally identifying neural states and configurations with psychological attributes.” This is a provocative claim indeed. If Bennett (...) and Hacker are right, then a sizeable number of philosophers, cognitive scientists, neuroscientists, etc., subscribe to a view that is not merely false, but strictly meaningless. In this article I show that Bennett and Hacker's arguments against NM, whether construed as arguments for the meaninglessness of or the falsity of the thesis, cannot withstand scrutiny: when laid bare they are found to rest upon highly dubious assumptions that either seriously mischaracterize or underestimate the resources of the thesis.

Certain features of perception – the quale red, for example, and other qualia – must be regarded as additions to the materialist neurophysiological picture of perception. The perception of three-dimensional volumetric objects can also be seen as qualitative additions to the neurophysiological processes in the brain, possibly without additions to the information content.

Type materialism is a theory of the place of states of phenomenal consciousness in nature. It is the theory that qualitative mental states are type identical with certain neuroscientific states. This chapter examines this theory and discusses some required background details. There are currently a number of scientific projects that are aimed at finding the neural correlates of states of phenomenal consciousness. Whether any of these projects will succeed is of course an empirical issue. Type materialism for (...) phenomenal consciousness is the view that types of states of phenomenal consciousness are identical with their strict neuroscientific correlates. If type materialism is true, then states of phenomenal consciousness are causally efficacious; for they are neuroscientific states with causal effects. Type materialism allows that there can be phenomenal consciousness in actual “absent folk role” cases. The chapter distinguishes type materialism from representationalism and psychofunctionalism.

The centerpiece of the scientific study of consciousness is the search for the neural correlates of consciousness. Yet science is typically interested not only in discovering correlations, but also – and more deeply – in explaining them. When faced with a correlation between two phenomena in nature, we typically want to know why they correlate. The purpose of this chapter is twofold. The first half attempts to lay out the various possible explanations of the correlation between consciousness and its (...) neural correlate – to provide a sort of “menu” of options from which we probably would ultimately have to choose. The second half raises considerations suggesting that, under certain reasonable assumptions, the choice among these various options may be in principle underdetermined by the relevant scientific evidence.

This essay is an analysis of conscious perception and conscious memory. It tries to show that percepts and mental images (roughly, experientially, the same as Hume's "impressions and ideas") are sets of particles at the perceived stimulus objects and at the remembered stimulus objects. It is thus a theory of direct perception and direct memory, and a materialism but not a central state materialism. The percept (we claim) is an "appearance" of the stimulus object particles (perceived object particles) (...) which is due to the way the particles at the perceived object are interconnected (interrelated) by the networks of stimuli-plus-neuron-impulses starting from them. The same is true of the mental image. This essay is primarily an analysis of such networks--to show, we claim, how they make the sets of object particles seem to have sense qualities and gestalts and other properties of percepts and mental images.

The higher-order thought (HOT) theory of consciousness is a reductive representational theory of consciousness which says that what makes a mental state conscious is that there is a suitable HOT directed at that mental state. Although it seems that any neural realization of the theory must be somewhat widely distributed in the brain, it remains unclear just how widely distributed it needs to be. In section I, I provide some background and define some key terms. In section II, I (...) argue against the view that HOT theory should treat first-order (i.e. world-directed) conscious states as requiring prefrontal cortical activity though it is reasonable to suppose that conscious states are realized in the brain. In section III, I then explore some of the key background metaphysical issues involved in understanding the nature of consciousness, such as the debate between realism and idealism as well as the prospects for solving the so-called “hard problem” of consciousness. Some of the differences in question often mirror the traditional differences between Western and Eastern perspectives on the nature of consciousness. Overall, I argue that some form of realism and physicalism is more plausible than the opposing views. I also argue that materialists (and especially HOT theorists) can offer plausible replies to the hard problem. (shrink)

This paper argues in unprecedented empirical and philosophical detail that, given only what science has discovered about pain, we should prefer the materialist hypothesis that pains are purely material over the dualist hypothesis that they are immaterial. The empirical findings cited provide strong evidence for the thesis of empirical supervenience: that to every sort of introspectible change over time in pains, or variation among pains at a time, there corresponds in fact a certain sort of simultaneous neural change over (...) time, or variation at a time. The empirical supervenience of pain on the neural is shown in turn to favor the hypothesis that pains are, in a sense that is made precise, purely material. (shrink)

This is a book about sensory states and their apparent characteristics. It confronts a whole series of metaphysical and epistemological questions and presents an argument for type materialism: the view that sensory states are identical with the neural states with which they are correlated. According to type materialism, sensations are only possessed by human beings and members of related biological species; silicon-based androids cannot have sensations. The author rebuts several other rival theories, and explores a number of (...) important issues: the forms and limits of introspective awareness of sensations, the semantic properties of sensory concepts, knowledge of other minds, and unity of consciousness. The book is a significant contribution to the philosophy of mind, and has much to say to psychologists and cognitive scientists. (shrink)

Central-state materialism is a very strong, but also very exciting theory of mind according to which each mental state is identical with a state of the central nervous system. CSM thus goes considerably beyond early versions of the identity theory of mind, since those early accounts held only that sensations are to be identified with neural events. CSM, by contrast, is a thesis about all mental states; every mental state is held to be a state of the central (...) nervous system. In fact, as we will see shortly, CSM is an even more sweeping thesis than this formulation of it suggests, since it is not concerned simply with mental states.One prominent defender of CSM, David Armstrong, has maintained that CSM can be established by means of a two-step argument.

Glenn Pearce, labels the identification of the firing of one's pain centres in the brain with feeling pain ‘a naive view,’ the refutation of which cannot much threaten any serious version of materialism.

Just to take a recent example, James Cornman and Keith Lehrer, (...) trying to get around the objection to the identity theory that the language of neural processes and the language of feeling pains belong to different linguistic categories, suggest that the materialist could devise a new term to refer to the same entity across categories: ‘fibain.’They write,He would then claim that there are fibains, that is, entities with those properties usually associated with pains, and also with the properties usually associated with firing C-fibers.

The human mind is essentially a metamind. Autonomy, knowledge, preference, acceptance, consciousness, and the content of thought all incorporate metamental ascent to a higher level beyond first level belief and desire. The primary function or role of metamental ascent is conflict resolution and higher order evaluation. An infinite regress of metamental ascent is avoided by a mental loop of keystone states which refer back to themselves yielding autonomy and knowledge without paradox. The metamental loop is, moreover, compatible with materialism, (...) even eliminative materiahsm. Vector activation in the brain averages neural impulses, and conflict resolution in the brain, like interpersonal conflict resolution, is obtained from weighted averaging. The resolution of the conflict is a fixed point vector of integrative weights which yields itself back forming a neural loop. Thus, neurophysiology recapitulates metamentality. (shrink)

Resumen En este trabajo se realiza un análisis exploratorio sobre lo que se ha venido concibiendo como un nuevo campo del saber científico desde hace algunas décadas, nos referimos a la neuroteología.

In his "Materialism without Reductionism: What Materialism Does not Entail," Richard Boyd answers Kripke's challenge to materialists to come up with a way to explain away the apparent contingency of mind-brain identities. Boyd accuses Kripke of an imaginative myopia manifesting itself as a failure to realize that the more theoretical term in the identity is fixed by contingent descriptions - descriptions that might pick out otherworldly kinds of neural events where C-fibres are absent. If this is something (...) we can confuse in the imagination with actual C-fibre firings, then we have an explanation of the apparent contingency of the necessary identity 'Pain=C-fiber firings.' However, for this to succeed it must be the case that the reference of 'C-fiber firings'€™ is fixed by some contingent description, which is false. Boyd, I submit, has failed to answer Kripke'€™s challenge after all. (shrink)

Deep appreciation of the relevance of emotion to epistemology requires a rich account of how emotional mental states such as happiness, sadness and desire interact with cognitive states such as belief and doubt. Analytic philosophy since Gottlob Frege and Bertrand Russell has assumed that such mental states are propositional attitudes, which are relations between a self and a proposition, an abstract entity constituting the meaning of a sentence. This chapter shows the explanatory defects of the doctrine of propositional attitudes, and (...) proposes instead that beliefs, desires, and emotions should be construed naturalistically using current understanding of brain mechanisms. Mental states are patterns of neural activity, not relations between dubious entities such as selves and propositions. From this perspective, it becomes easy to see how cognition and emotion are intertwined, and hence how emotions can be integral to epistemology. I begin by reviewing some of the ways in which emotions are relevant to epistemology: as frequent contributors to the growth of knowledge, as sometime impediments to knowledge acquisition, and as components of knowledge about persons and morality. I then argue that propositional attitudes do not exist, because the selves and the propositions that they purportedly relate do not exist. Thus the doctrine of propositional attitudes is as useless for epistemology as it is for explaining human action. I argue for an alternative construal of mental states as patterns of neural activity, and July 23, 2007 describe how it is possible to give a theoretically rich and empirically supported account of the neurophysiological interconnections of cognition and emotion. Finally, I discuss the epistemological significance of this naturalistic, materialist reconstrual of cognitions and emotions. (shrink)

In his 1994 paper, neuroscientist Benjamin Libet affirmed that he found a way to test the interaction between the mind and the brain. He believed that this procedure would also test the reality of a non-physical mind, emerging from neural activity. In 2000 John Searle objected to Libet’s evident dualism, affirming that the mind is not a hypothesis to test but a datum to be explained. According to Searle, Libet’s problem arose from accepting the Cartesian distinction of ‘mind’ and (...) ‘body’, obsolete categories from an old philosophy. Searle’s solution implied the rejection both of dualism and reductive materialism, suggesting a non-reductive materialism. This first-person ontology, as Searle calls it, aims at preserving, against reductive materialism, the essential features of consciousness, i.e. subjective, qualitative and unified. Searle argued, however, that the nature of consciousness remained biological. Dan Zahavi’s thesis is that a phenomenological approach to the self and consciousness can offer a complementing alternative to the contemporary comprehension of the nature of consciousness. Engaged in an open dialogue with neuroscience and cognitive science in his dealings with consciousness, Zahavi holds, nonetheless, that this notion cannot be completely understood without reference to the notion of the self. Thus, this paper will analyse Zahavi’s ideas about the self and consciousness in Subjectivity and Selfhood as to evaluate whether his phenomenological approach is able to overcome the materialist tones of Searle’s philosophy of mind, opening the possibility of a non-reductive comprehension of human beings.

So-called identity theories that postulate the identity of mental phenomena with brain states are usually associated with materialistic ontology. However, the historical picture of the actual attempts at spelling out the mind–brain identities is more complex. In the eighteenth century such identities were most enthusiastically proposed by dualists, whereas non-reductionistic materialists such as Diderot tried to get along without them. In the nineteenth century physiologists such as Broca, Charcot and Wernicke, who postulated discrete and localizable neural correlates for ideas (...) and mental images, ended up, despite their professed materialism, defending theories that resembled Cartesian schemes and the theories of their eighteenth-century dualistic predecessors. Some problems resulting from the use of these theoretical models postulating local and discrete traces, images or representations in the brain in the context of materialist ontology are obviously related to their dualistic origins and to the fact that they are necessarily bound up with dualistic presuppositions. In the context of the criticism of the nineteenth-century memory trace paradigm it is, however, important to bear in mind that functional localization as such is not dependent on the notion of localizable representations. Nor are materialist theories of the mind necessarily dependent on postulating specific type–type identities between the mental and the physiological. (shrink)

The paper analyzes the meaning of color terms within the framework of Kaplan's character theory (which, when generalized to a treatment of hidden indexicality or dependence on the context world, can perfectly accommodate Kripke's notions of apriority and of (metaphysical) necessity). It explains this framework and why it might be fruitfully applied to color terms. Then it defends six theses: that (1) the predicate "is red" and (2) even the relation "appears red to" are hidden indexicals (i.e., have, as used (...) in English, different extensions in different context worlds), that (3) the phenomenal, the comparative, and the epistemic reading of "appears red to" are not three different readings, but reflect the context world dependence of this term, that (4) the statement "x is red iff x would appear red to most English-speaking people under normal conditions" is a priori in English, but analytic only in one reading and not in another, and that these observations account well for the epistemology of color terms and allow us to be metaphysically conservative by claiming that our context world is presumably such that (5) the statement "x appears red to y iff x (appropriately) causes y to be in a certain (disjunctive) neural state N" is necessarily true and (6) the statement "x is red iff the reflectance spectrum of the surface of x is of some (disjunctive) kind R" is necessarily true as well.

The essays gathered here demonstrate and justify the excitement and promise of cognitive historicism, providing a lively introduction to this new and quickly growing area of literary studies. Written by eight leading critics whose work has done much to establish the new field, they display the significant results of a largely unprecedented combination of cultural and cognitive analysis. The authors explore both narrative and dramatic genres, uncovering the tensions among presumably universal cognitive processes, and the local contexts within which complex (...) literary texts are produced. Alan Richardson's opening essay evaluates current approaches to the study of literature and cognition, locating them on the map of recent literary studies, indicating their most compelling developments to date, and suggesting the most promising future directions. The seven essays that follow provide innovative readings of topics ranging from Shakespeare (Othello, Macbeth, Cymbeline, The Rape of Lucrece) through Samuel Richardson's Clarissa, to contemporary authors Ian McEwan and Gilbert Sorrentino. They underscore some of the limitations of new historicist and post-structuralist approaches to literary cultural studies while affirming the value of supplementing rather than supplanting them with insights and methods drawn from cognitive and evolutionary theory. Together, they demonstrate the analytical power of considering these texts in the context of recent studies of cultural universals, 'theory of mind, ' cognitive categorization and genre, and neural-materialist theories of language and consciousness. This groundbreaking collection holds appeal for a broad audience, including students and teachers of literary theory, literary history, cultural studies, and literature and science studies. (shrink)

In this chapter, I first review and assess evidence regarding brain damage or neural abnormalities associated with some psychopathologies and cognitive deficits, such as hemispatial neglect, agnosias, amnesia, somatoparaphrenia, and others. It becomes clear just how closely normal mental functioning and consciousness depend upon normal brain functioning as well as how some very specific mental changes occur when, and only when, very specific brain damage occurs. I then explore the metaphysical implications of these results with respect to the nature (...) of mind and consciousness. In particular, I examine the plausibility of materialism, roughly the view that mental processes are brain processes, in light of the evidence discussed and in contrast to a dualist conception of the mind (whereby mental states are not physical in some sense). I also explore the prospects for a conscious afterlife based both on the brain damage evidence adduced and the metaphysical implications discussed. (shrink)

Three decades ago, William Ramsey, Steven Stich & Joseph Garon put forward an argument in favor of the following conditional: if connectionist models that implement parallelly distributed processing represent faithfully human cognitive processing, eliminativism about propositional attitudes is true. The corollary of their argument (if it proves to be sound) is that there is no place for folk psychology in contemporary cognitive science. This understanding of connectionism as a hypothesis about cognitive architecture compatible with eliminativism is also endorsed by Paul (...) Churchland, a radical opponent of folk psychology and a prominent supporter of eliminative materialism. I aim to examine whether current connectionist models based on long-short term memory (LSTM) neural networks can back up these arguments in favor of eliminativism. Nonetheless, I will rather put my faith in the eliminativism of the limited domain. This position amounts to the claim that even though connectionist cognitive science has no need whatsoever for folk psychology qua theory, this does not entail the illegitimacy of folk psychology per se in other scientific domains, most notably in humanities, but only on condition that one regards folk psychology as mere heuristics.

In Measuring the Immeasurable Mind: Where Contemporary Neuroscience Meets the Aristotelian Tradition, Matthew Owen argues that despite its nonphysical character, it is possible to empirically detect and measure consciousness. -/- Toward the end of the previous century, the neuroscience of consciousness set its roots and sprouted within a materialist milieu that reduced the mind to matter. Several decades later, dualism is being dusted off and reconsidered. Although some may see this revival as a threat to consciousness science aimed at measuring (...) the conscious mind, Owen argues that measuring consciousness, along with the medical benefits of such measurements, is not ruled out by consciousness being nonphysical. Owen proposes the Mind-Body Powers model of neural correlates of consciousness, which is informed by Aristotelian causation and a substance dualist view of human nature inspired by Thomas Aquinas, who often followed Aristotle. In addition to explaining why there are neural correlates of consciousness, the model provides a philosophical foundation for empirically discerning and quantifying consciousness. En route to presenting and applying the Mind-Body Powers model to neurobiology, Owen rebuts longstanding objections to dualism related to the mind-body problem. With scholarly precision and readable clarity, Owen applies an oft forgotten yet richly developed historical vantage point to contemporary cognitive neuroscience. (shrink)

A key working hypothesis in neuroscience is ‘materialistic reductionism’, i.e., the assumption whereby all physiological, behavioral or cognitive phenomena is produced by localized neurochemical brain activation (but not vice versa). However, analysis of sub-threshold Weber’s psychophysical stimulation indicates its computational irreducibility to the direct interaction between psychophysical stimulation and any neuron/s. This is because the materialistic-reductionistic working hypothesis assumes that the determination of the existence or non-existence of any psychophysical stimulation [s] may only be determined through its direct interaction [di1] (...) with a given neuron/s [N] that together forms the ‘neural registry’ computational level [NR/di1]. But, this implies that in cases of (initial) sub-threshold (sensory-specific) psychophysical stimulation which is increased above the sensory-specific threshold but below Weber’s psychophysical ‘dv’—the psychophysical computational processing [PCP] produces an apparently ‘computationally indeterminate’ output. This is because materialistic reductionism asserts the contingency of PCP upon the existence of a direct interaction between ‘s’ and ‘N’ within the NR/di1 level, but in the special case of Weber’s sub-threshold psychophysical stimulation the same PCP/di1 also asserts the non-existence of ‘s’ (as demanded by Weber’s psychophysical law). However, given robust empirical evidence indicating the capability of PCP to determine whether (or not) ‘s’ exists, we must conclude that PCP may not be carried out from within NR’s direct interaction between a particular psychophysical stimulation and any set of neuron/s in the brain. Hence, the Duality Principle asserts the conceptual irreducibility of sub-threshold psychophysical stimulation to any direct NR/di1: s-N interaction, thereby challenging the current materialistic-reductionistic assumption.

The materialist critics argue that insuperable difficulties are encountered by the hypothesis that immaterial mental events such as thinking can act in any way on material structures such as neurons of the cerebral cortex, as is diagrammed in Fig. 8. Such a presumed action is alleged to be incompatible with the conservation laws of physics, in particular of the First Law of Thermodynamics. This objection would certainly be sustained by 19th century physicists and by neuroscientists and philosophers who are still (...) ideologically in the physics of the 19th century, not recognizing the revolution wrought by quantum physicists in the 20th century. Unfortunately it is rare for a quantum physicist to dare an intrusion into the brain-mind problem. But in a recent book the quantum physicist Margenau (1984) makes a fundamental contribution. It is a remarkable transformation from 19th century physics to be told (p. 22): "that some fields, such as the probability field of quantum mechanics carry neither energy nor matter." He goes on (p. 96) to state: "In very complicated physical systems such as the brain, the neurons and sense organs, whose constituents are small enough to be governed by probabilistic quantum laws, the physical organ is always poised for a multitude of possible changes, each with a definite probability; if one change takes place that requires energy, or more or less energy than another, the intricate organism furnishes it automatically. Hence, even if the mind has anything to do with the change, that is if there is a mind-body interaction, the mind would not be called upon to furnish energy." In summary (p. 97) Margenau states that: "The mind may be regarded as a field in the accepted physical sense of the term. But it is a nonmaterial field; its closest analogue is perhaps a probability field. It cannot be compared with the simpler nonmaterial fields that require the presence of matter (e.g. gravity) nor does it necessarily have a definite position in space. And so far as present evidence goes it is not an energy field in any physical sense, nor is it required to contain energy in order to account for all known phenomena in which mind interacts with brain". In formulating more precisely the dualist hypothesis of mind-brain interaction, the initial statement is that the whole world of mental events (World 2) has an existence as autonomous as the world of matter-energy (World I ) (Fig. 1). The present interactionist hypothesis does not relate to these ontological problems, but merely to the mode of action of mental events on neural events, that is of the nature of the downward arrows across the frontier in Fig. 8. Following Margenau (1984) the hypothesis is that mind-brain interaction is analogous to a probability field of quantum mechanics, which has neither mass nor energy, yet can cause effective action at microsites. More specifically it is proposed that the mental concentration involved in intentions (Figs. 7, 8) or attention (Fig. 4) or planned thinking (Figs. 5, 6) can cause neural events by a process analogous to the probability fields of quantum mechanics. -/- We can ask: what neural events could be appropriate recipients for mental fields that are analogous to quantal probability fields? Already we may have the answer in recent discoveries on the nature of the synaptic mechanism whereby one nerve cell communicates with another. (shrink)

Philosophers have argued that on the prevailing theory of mind, functionalism, the fact that mental states are multiply realizable or can be instantiated in a variety of different physical forms, at least in principle, shows that materialism or physical is probably false. A similar argument rejects the relevance to psychology of connectionism, which holds that mental states are embodied and and constituted by connectionist neural networks. These arguments, I argue, fall before reductios ad absurdam, proving too much -- (...) they apply as well to genes, which are multiply realizable, but the reduction of which to DNA is one the core cases of scientific reductive explanation, a reduction if anything is. -/- I suggest that psychology, like biology, be what I call "provincialized," abandon claims to universal validity, except as an idealization, and treat different classes of cognizers differently from an an explanatory perspective. This would permit specifies specific, or more precisely, provincial reductions of different psychologies that might be multiply realized if such reductions were available. Connectionism may be the foundation of a reduction of human psychology, and thus biology and connectionism retain their relevance to psychology, and physicalism or materialism is consistent with functionalism.

In Freedom: An Impossible Reality, Ray Tallis argues that we escape imprisonment by causal determinism, and thus gain free will, by the virtual distance from natural laws afforded us by intentionality, a human capacity that he claims cannot be naturalized. I respond that we can’t know in advance that intentionality will never be subsumed by science, and that our capacities to entertain possibilities and decide among them are natural cognitive endowments that supervene on generally reliable neural processes. Moreover, any (...) disconnection from the multi-level determinants that account for human behavior cannot augment, but would likely undermine, effective human agency. Our full inclusion in nature, understood in terms of a pragmatic, explanatory determinism, is therefore not a prison from which we need to escape. (shrink)

To a significant extent, mainstream Western philosophy is not empirically minded. The neurophilosophy of the Churchlands seems to exhibit the greatest divergence from this orientation by far. Extending and neuralizing Quine’s naturalism, the Churchlands have been known to challenge most assumptions and principles of contemporary mainstream analytic and even existing naturalistic philosophies. Even the philosophers who identify themselves as full-blown naturalists have an inexplicably negative attitude toward the Churchlands. For many philosophers of the mind, the Churchlands’ problem is not that (...) they are philosophically wrong, but that they have no philosophical approach that could be wrong. They are nonphilosophers working at philosophy departments. Proper philosophy is not what they do or think they are doing. In this article, I argue to the contrary. The Churchlands would seem surprisingly moderate, and neither trivial nor near-trivial, when closely scrutinized. (shrink)

The conceivability argument against materialism, originally raised by Saul Kripke and then reformulated, among others, by David Chalmers holds that we can conceive of the distinctness of a phenomenal state and its neural realiser, or, in Chalmers’ variation of the argument, a zombie world. Here I argue that both phenomenal and natural kind terms are ambiguous between two senses, phenomenal and natural, and that the conceivability argument goes through only on one reading of a term. Thus, the antimaterialist (...) has to provide some reasons independent of anti-materialism itself to favour that reading of a term that supports his or her argument. Given that there are no such independent reasons, I conclude that we should put more weight on empirical considerations than on a priori discussion in resolving the question concerning the identity between a phenomenal state and its neural realiser.

This book introduces concepts in philosophy of mind and neurophilosophy. Inside, three scholars offer approaches to the problems of identity, consciousness, and the mind. In the process, they open new vistas for thought and raise fresh controversies to some of the oldest problems in philosophy. The first chapter focuses on the identity problem. The author employs an explanatory model he christened sense-phenomenalism to defend the thesis that personal identity is something or a phenomenon that pertains to the observable/perceptible aspect of (...) the human person. The next chapter explores the problem of consciousness. It deploys the new concept equiphenomenalism as a model to show that mental properties are not by-products but necessary products of consciousness. Herein, the notion of qualia is a fundamental and necessary product that must be experienced simultaneously with neural activities for consciousness to be possible. The last chapter addresses the mind/body problem. It adopts the new concept proto-phenomenalism as an alternative explanatory model. This model eliminates the idea of a mind. As such, it approaches the mind-body problem from a materialistic point of view with many implications such as, the meaning of our existence, the possibility of thought engineering as well as religious implications.

In this paper I argue that much of the confusion and mystery surrounding the concept of "self" can be traced to a failure to appreciate the distinction between the self as a collection of diverse neural components that provide us with our beliefs, memories, desires, personality, emotions, etc (the epistemological self) and the self that is best conceived as subjective, unified awareness, a point of view in the first person (ontological self). While the former can, and indeed has, been (...) extensively studied by researchers of various disciplines in the human sciences, the latter most often has been ignored -- treated more as a place holder attached to a particular predicate of interest (e.g., concept, reference, deception, esteem, image, regulation, etc). These two aspects of the self, I contend, are not reducible -- one being an object (the epistemological self) and the other a subject (the ontological self). Until we appreciate the difficulties of applying scientific methods and analysis to what cannot be reduced to an object of inquiry without stripping it of its essential aspect (its status as subject), progress on the "self", taken as a pluralistic construct, will continue to address only one part of the problems we face in understanding this most fundamental aspect of human experience.

In this highly original work, Teed Rockwell rejects both dualism and the mind-brain identity theory. He proposes instead that mental phenomena emerge not merely from brain activity but from an interacting nexus of brain, body, and world. The mind can be seen not as an organ within the body, but as a "behavioral field" that fluctuates within this brain-body-world nexus. If we reject the dominant form of the mind-brain identity theory -- which Rockwell calls "Cartesian materialism" -- and accept (...) this new alternative, then many philosophical and scientific problems can be solved. Other philosophers have flirted with these ideas, including Dewey, Heidegger, Putnam, Millikan, and Dennett. But Rockwell goes further than these tentative speculations and offers a detailed alternative to the dominant philosophical view, applying pragmatist insights to contemporary scientific and philosophical problems. Rockwell shows that neuroscience no longer supports the mind-brain identity theory because the brain cannot be isolated from the rest of the nervous system; moreover, there is evidence that the mind is hormonal as well as neural. These data, and Rockwell's reanalysis of the concept of causality, show why the borders of mental embodiment cannot be neatly drawn at the skull, or even at the skin. Rockwell then demonstrates how his proposed view of the mind can resolve paradoxes engendered by the mind-brain identity theory in such fields as neuroscience, artificial intelligence, epistemology, and philosophy of language. Finally, he argues that understanding the mind as a "behavioral field" supports the new cognitive science paradigm of dynamic systems theory. (shrink)

In visual science the term filling-inis used in different ways, which often leads to confusion. This target article presents a taxonomy of perceptual completion phenomena to organize and clarify theoretical and empirical discussion. Examples of boundary completion (illusory contours) and featural completion (color, brightness, motion, texture, and depth) are examined, and single-cell studies relevant to filling-in are reviewed and assessed.

Philosophers and scientists have long speculated about the nature of color. Atomists such as Democritus thought color to be "conventional," not real; Galileo and other key figures of the Scientific Revolution thought that it was an erroneous projection of our own sensations onto external objects. More recently, philosophers have enriched the debate about color by aligning the most advanced color science with the most sophisticated methods of analytical philosophy. In this volume, leading scientists and philosophers examine new problems with new (...) analytic tools, considering such topics as the psychophysical measurement of color and its implications, the nature of color experience in both normal color-perceivers and the color blind, and questions that arise from what we now know about the neural processing of color information, color consciousness, and color language. Taken together, these papers point toward a complete restructuring of current orthodoxy concerning color experience and how it relates to objective reality. Kuehni, Jameson, Mausfeld, and Niederee discuss how the traditional framework of a three-dimensional color space and basic color terms is far too simple to capture the complexities of color experience. Clark and MacLeod discuss the difficulties of a materialist account of color experience. Churchland, Cohen, Matthen, and Westphal offer competing accounts of color ontology. Finally, Broackes and Byrne and Hilbert discuss the phenomenology of color blindness. Contributors: Justin Broackes, Alex Byrne, Paul M. Churchland, Austen Clark, Jonathan Cohen, David R.

In simple terms, psychological dualism purports that there is an underlying complementary, non-material/physical cognitive component associated with a living organism. Thus mind would not simply be an expression of brain function. Science embraces materialism and generally views any form of dualism with disdain. Yet there are a number of accepted phenomena that are suggestive of dualism and in particular are consistent with the existence of souls. One such phenomenon is terminal lucidity, in which people inexplicably return to mental coherence (...) shortly before death after appearing to be lost to “dull, unconscious, or mentally ill” conditions, sometimes for years. The physical/neural plausibility of such rejuvenation is difficult to imagine. Discussions herein introduce terminal lucidity primarily based on some clinal reports. Next, the medium-based communications reviewed in Chris Carter’s Science and the After Life Experience are used to introduce the concept of a soul. Further, a dynamic suggested in Carter’s coverage is then used to offer a simple explanation for terminal lucidity. Finally, for additional context, the state of neuroscience is considered and some brief conclusions are given. (shrink)

ABSTRACT The individual-community relationship has always been one of the most fundamental topics of social sciences. In sociology, this is known as the micro-macro relationship while in economics it refers to the processes, through which, individual actions lead to macroeconomic phenomena. Based on philosophical discourse and systems theory, many sociologists even use the term "emergence" in their understanding of micro-macro relationship, which refers to collective phenomena that are created by the cooperation of individuals, but cannot be reduced to individual actions. (...) "Emergence" theories attempt to explain the nature of society as a complex system by examining how individuals and their relationships lead to the creation of integrated and macro-social phenomena such as markets, educational systems, cultural beliefs, and shared social practices. As a prelude to activity, every researcher has to answer the question from the methodological point of view, how is it possible to study the behavior of social groups and how can we gain knowledge about the laws related to social groups? Anyone who deals with humanities and social sciences or any reality and phenomenon that affects human beings, inevitably deals with the reality that is emerging. In fact, emergence occurs when one level of reality emerges radically from another level. Examples of emergent levels of reality include how the mind emerges from the body; or the way society emerges from human beings. Therefore, when there is an emerging factor, different scientific disciplines should be used, because it is inevitable to talk about social affairs, psychology and neurobiology, as well as physical and even chemical. -/- INTRODUCTION Since its beginning in the 19th century, sociology has faced the fundamental question of what a social phenomena stands for? At a glance, sociologists deal with the study of social groups, collective behavior, institutions, social structures, social networks, and social dynamics, and ultimately all such phenomena are composed of individuals. Therefore, social phenomena seem to have no independent ontological status, and in this case, sociology is ultimately about reducible individuals. Different approaches about the micro-macro relationship, using the concept of "emergence", argue that although collective phenomena are created by individuals, they cannot be reduced to individual action. The term "emergence" is used to distinguish "emergent results" from " Procedural results". Results are called Procedural that can only be calculated by adding or subtracting the causes that act together. On the contrary, they are emergent outcomes that are qualitatively novel compared to the causes from which they originate. An example of such emergent results is mental characteristics that emerge from neural processes, but are not considered among the characteristics of neural processes of components - which are their origin. Philosophical debates about emergentism and reductionism focus on the mind-brain relationship, but as many philosophers have noted, they can be generalized to apply to any hierarchical set of features. The cognitive revolution reactivated a 19th century controversy between theorists of Identity and dualism. The theorists of Identity believe in reductionist materialism and elimination of metaphysics, according to which the mind is nothing more than the biological, while the dualists believe that the mind and the brain are distinct from each other. Emergence has been considered as a third way between the theories of Identity and dualism. -/- METHODOLOGY Interdisciplinarity Is fundamentally indicated by the dominance of open systems as well as social and emerging systems at different levels. Therefore, as long as we are facing a new emergentism, there will necessarily be different fields and an interdisciplinary method. The commonality of social sciences and cognitive sciences on the issue of emergence provides the possibility of interaction and exchange of concepts between these two for deeper research. Therefore, in this research, apart from the concepts of Subvenience and downward causation, we have used multiple realization and wildly disjunctive, which are used to explain the emerging concept in cognitive sciences, including neurobiology, psychology, and philosophy. For analytical and interdisciplinary approaches, after examining the concepts of subvenience, and wildly disjunctive, Individualistic and collectivist emergentism have been reviewed. And then their adequacy is criticized and evaluated in meeting strong emergence conditions. -/- FINDINGS Philosophers of the mind have been able to define the conditions of irreducibility and downward causation, which are essential for strong emergence, by using the principle of subvenience with the help of multiple realization and wildly disjunctive principles. Therefore, by definition, emergentist individualism suffers from the problem of how to explain downward causality and irreducibility, and emergentist collectivism faces the challenge of reification. The analysis of the challenges facing the two methodological approaches of individualism and collectivism leads us to three unresolved issues about the emerging phenomenon, which are realism, downward causality, and mechanism. Despite the differences in the stances of these two approaches regarding the aforementioned triple problems, individualists and collectivists both agree that some social characteristics are reducible; and some others are irreducible due to their complexity, the determination of which, depends on the case study of the mechanism of emergence of each social characteristic. -/- CONCLUSION An emergence that is consistent with reductionism is called a weak emergence. And strong emergence includes the principle of irreducibility and downward causality. According to strong emergence, the characteristics of social phenomena have downward causal power, which cannot be reduced to the causal forces. The principle of subvenience, together with multiple realization and wildly disjunctive, can provide the conditions of irreducibility and downward causality, which are essential conditions of strong emergence. Based on the philosophical analysis of two methodological approaches, individualist and collectivist, it can be concluded that emergentist individualism suffers from the problem of how to explain downward causality and irreducibility, and reification collectivism faces the challenge of reification. The analysis of the problems faced by these two approaches leads us to three unresolved issues, which are realism, downward causality, and mechanism. individualist emergentists acknowledge the existence of emergent social characteristics, but despite this, they believe that these characteristics are not real but merely analytical constructs that require explanation based on individuals and their mutual actions. But collectivists argue that emergentism yields a categorical ontology and supports social realism. They accept the dependence of social characteristics on individuals, but claim that social entities and structures are ontologically independent. Individualists and collectivists both agree that some social characteristics are reducible; and others are irreducible due to their complexity; and the only way to recognize this is to engage in empirical studies of the mechanisms and temporal processes of "emergence" that create social characteristics. -/- NOVELTY The newness of this compact article is as follows: a) Presenting an interdisciplinary approach using the analysis of philosophy of cognitive sciences, including the philosophy of mind, neurobiology and psychology to formulate the issue of social emergence; b) Criticizing individualist and collectivist methodological approaches to the issue of social emergence and explaining the sufficiency and shortcomings of both in providing weak and strong emerging conditions; c) Explaining and categorizing the challenges facing methodological approaches in explaining the phenomenon of social emergence, in three categories: realism, downward causality, and mechanism.

I argue, contrary to wide-spread opinion, that belief-desire psychology is likely to reduce smoothly to neuroscientific theory. I therefore reject P.M. Churchland's eliminativism and Fodor's nonreductive materialism. The case for this claim consists in an example reduction of the desire construct to a suitable construct in neuroscience. A brief account of the standard view of intertheoretic reduction is provided at the outset. An analysis of the desire construct in belief-desire psychology is then undertaken. Armed with these tools, the paper (...) moves to an examination of the neural structures responsible for the production of motor behavior. This examination provides the basis for a theory of the neurophysiology of desire. A neurophysiological state is isolated and claimed to be type-identical to the state of desiring. (shrink)
