Defenders of the Knowledge Argument contend that physicalism is false because knowing all the physical truths is not sufficient to know all the truths about the world. In particular, proponents of the Knowledge Argument claim that physicalism is false because the truths about the character of conscious experience are not knowable from the complete set of physical truths. This dissertation is a defense of the Knowledge Argument. Chapter one characterizes what physicalism is and provides support for the claim that if (...) knowing all the physical truths is not sufficient to know all the truths about the world, then physicalism is false. In chapter two, I defend the claim that knowing all the physical truths is not sufficient for knowing all the truths about the world. In addition to mounting a prima facie case for the knowledge intuition, I present and defend an epistemology grounded in direct acquaintance to provide a more substantive argument to accept it. Chapters three through five address the physicalist objections to the Knowledge Argument. The first set of objections advocates that knowing all the physical truths is, in fact, sufficient for knowing all the truths about the world. The next set of objections admits that there is some sense in which knowing all the physical truths is not sufficient for knowing all the truths about the world. However, these objections maintain that the kind of knowledge that is absent from the complete set of physical truths is know-how or knowledge by acquaintance, and not factual or propositional knowledge. The final set of objections maintain that the kind of propositional knowledge that is left out of the complete set of physical truths is compatible with physicalism. My response to these objections is part of advancing my prima facie case for the Knowledge Argument. The final chapter addresses a structural question that pertains to the Knowledge Argument. Some philosophers have maintained that the structure of the Knowledge Argument invites a kind of self-refutation of any systematic account of reality. The concern is that the Knowledge Argument proves too much, and that the dualist who uses the argument to refute physicalism risks the argument defeating his own position. I will argue that the Knowledge Argument does not refute dualism. (shrink)

This is a bibliography of books and articles on consciousness in philosophy, cognitive science, and neuroscience over the last 30 years. There are three main sections, devoted to monographs, edited collections of papers, and articles. The first two of these sections are each divided into three subsections containing books in each of the main areas of research. The third section is divided into 12 subsections, with 10 subject headings for philosophical articles along with two additional subsections for articles in cognitive (...) science and neuroscience. Of course the division is somewhat arbitrary, but I hope that it makes the bibliography easier to use. This bibliography has first been compiled by Thomas Metzinger and David Chalmers to appear in print in two philosophical anthologies on conscious experience . From 1995 onwards it has been continuously updated by Thomas Metzinger, and now is freely available as a PDF-, RTF-, or HTML-file. This bibliography mainly attempts to cover the Anglo-Saxon and German debates, in a non-annotated, fully formatted way that makes it easy to "cut and paste" from the original file. To a certain degree this bibliography also contains items in other languages than English and German - all submissions in other languages are welcome. Last update of current version: July 13th, 2001.

The human experience of meaning‐making lies at the roots of consciousness, creativity, and religious faith. It arises from the basic experience of separation from a loved object, suffered by all mammals, and, in general terms, from the experienced gap between ourselves and our environment. We fill the gap with transitional objects and symbols that reassure us of basic continuity in ourselves and in the world. These objects and symbols also serve the neurognostic function of demonstrating what the world is like. (...) Thus, humanity lives by faith, as manifested in its pattern‐making capacity, and not by literal sight. (shrink)

This article probes the evolutionary origins ofmoral capacities and moral agency. From thisit develops a theory of the guidancesystem of higher mind (GSHM). The GSHM is ageneral model of intelligence whereby moralfunctioning is integrated with cognitive,affective, and conative functioning, resultingin a flow of information between eight brainlevels functioning as an evaluative unitbetween stimulus and response.The foundation of this view of morality and ofcaring behavior is Charles Darwin's theory,largely ignored until recently, of thegrounding of morality in sexual instincts whichlater expand into (...) parental love. Also, PaulMacLean made these same connections in hisdevelopment of the triune brain theory, whichwas founded on observations of both sexual andaffectionate responses from stimulation oflimbic and paleocortical areas (that is, notthe most primitive areas) of monkey brains. This article relates the revolutionary areas ofDarwin and of MacLean together for the firsttime in an way intended to be accessible to arange of social and natural scientists. TheGSHM builds on and expands both of their workto develop a theory of the processing withinour brains of information screened by asequence of systems, social, future, moral,developmental, and managerial ``sensitivities.''Darwin's and MacLean's observations and theGSHM theory developed here argue against theold strict distinction between ``lower''emotional processes and ``higher'' rationalprocesses. In fact, MacLean, Karl Pribram, andothers have found that emotional responses areclosely tied to reason through the functions ofthe prefrontal cortex. Prefrontal function isclosely related to the development of moralsensibility and judgment. In particular, it isthe connections between prefrontal cortex andother brain areas that allow us to makedeliberate choices to be or not to be caring. These same connections allow us to learnculturally sensitive signals for when torelease or inhibit our cooperative oraggressive tendencies (both of which can beelicited by sexual displays in monkeys as wellas humans). These are closely tied to thesocial instinct in animals, and to thesocialization that children receive from theirparents (whom the clinical psychologist AlanSchore has described as providing a ``substituteprefrontal cortex'' for their very youngchildren). Higher levels of the GSHM modelsuch capabilities as thinking beyond thecurrent social situation to ``what could be'' anddialectical synthesis of apparent opposites,which are what allow humans the freedom todesign social realities to fit our moralsensibilities.

This entry concerns dualism in the philosophy of mind. The term ‘dualism’ has a variety of uses in the history of thought. In general, the idea is that, for some particular domain, there are two fundamental kinds or categories of things or principles. In theology, for example a ‘dualist’ is someone who believes that Good and Evil — or God and the Devil — are independent and more or less equal forces in the world. Dualism contrasts with monism, which is (...) the theory that there is only one fundamental kind, category of thing or principle; and, rather less commonly, with pluralism, which is the view that there are many kinds or categories. In the philosophy of mind, dualism is the theory that the mental and the physical — or mind and body or mind and brain — are, in some sense, radically different kinds of thing. Because common sense tells us that there are physical bodies, and because there is intellectual pressure towards producing a unified view of the world, one could say that materialist monism is the ‘default option’. Discussion about dualism, therefore, tends to start from the assumption of the reality of the physical world, and then to consider arguments for why the mind cannot be treated as simply part of that world.

In the visual system, the represented features of individual objects (shape, colour, movement, and so on) are distributed both in space and time within the brain. Representations of inner and outer event sequences arrive through different sense organs at different times, and are likewise distributed. Objects are nevertheless perceived as integrated wholes - and event sequences are experienced to form a coherent "consciousness stream." In their thoughtful article, Dennett & Kinsbourne ask how this is achieved.

In this paper I develop the thesis that dreams are essential to an understanding of waking consciousness. In the first part I argue in opposition to the philosophers Malcolm and Dennett that empirical evidence now shows dreams to be real conscious experiences. In the second part, three questions concerning consciousness research are addressed. (1) How do we isolate the system to be explained (consciousness) from other systems? (2) How do we describe the system thus isolated? (3) How do we reveal (...) the mechanisms on which this system is based? I suggest that empirical dream research combined with other empirical approaches can help us to sketch answers to all of these questions. I argue that the subjective form of dreams reveals the subjective, macro-level form of consciousness in general and that both dreams and the everyday phenomenal world may be thought of as constructed “virtual realities”. A major task for empirical consciousness research is to find out the mechanisms which bind this experienced world into a coherent whole. (shrink)

It is widely accepted that embodiment is crucial for any self-aware agent. What is less obvious is whether the body has to be real, or whether a virtual body will do. In that case the notion of embodiment would be so attenuated as to be almost indistinguishable from disembodiment. In this article I concentrate on the notion of embodiment in human agents. Could we be disembodied, having no real body, as brains-in-a-vat with only a virtual body? Thought experiments alone will (...) not suffice to answer this Cartesian question. I will draw on both philosophical arguments and empirical data on phantom phenomena. My argument will proceed in three steps. Firstly I will show that phantom phenomena provide a prima facie argument that real embodiment is not necessary for a human being. Secondly I will give a philosophical argument that real movement must precede the intention to move and to act. Agents must at least have had real bodies once. Empirical data seems to bear this out. Finally, however, I will show that a small number of aplasic phantom phenomena undermines this last argument. Most people must have had a real body. But for some people a partly virtual, unreal, phantom body seems to suffice. Yet though there is thus no knockdown argument that we could not be brains-in-a-vat, we still have good reasons to suppose that embodiment must be real, and not virtual. (shrink)

The debate between emergentists and reductionists rests on the observation that in many situations, in which it seems desirable to work with a coherent and unified discourse, key predicates fall into different groups, such that pairs of members one taken from each group, cannot be co-predicated of some common subject. Must we settle for ‘island’ discourses in science and human affairs or is some route to a unified discourse still open? To make progress towards resolving the issue the conditions under (...) which such segregations of predicates seem inexorable must be brought out. The distinction between determinable and determinate properties throws light on some aspects of this problem. Bohr’s concept of complementarity, when combined with Gibson’s idea of an affordances as a special class of dispositional properties is helpful. Several seeming problems melt away, for example, how it is possible for a group of notes to become hearable as a melody. The mind-body problem and the viability of the project of reducing biology to chemistry and physics are two issues that are more difficult to deal with. Are mental phenomena, such as feelings and memories emergent from material systems or are they actually material properties themselves? Are the attributes of living beings emergent from certain accidental but long running collocations of chemical reactions, or are they nothing but chemical phenomena? If emergent, in what way are they distinctive from that from which they emerge? (shrink)

A phenomenology of action is outlined, analyzing the structure of volition, kinesthesis, and perception in the experience of action, and, finally, the experience of embodiment in action. The intentionality of action is contrasted with that of thought and perception in regard to the role of the body, and the relations between an action, the experience of acting, and the context of the action are specified.

Consciousness is a mongrel concept: there are a number of very different "consciousnesses." Phenomenal consciousness is experience; the phenomenally conscious aspect of a state is what it is like to be in that state. The mark of access-consciousness, by contrast, is availability for use in reasoning and rationally guiding speech and action. These concepts are often partly or totally conflated, with bad results. This target article uses as an example a form of reasoning about a function of "consciousness" based on (...) the phenomenon of blindsight. Some information about stimuli in the blind field is represented in the brains of blindsight patients, as shown by their correct "guesses," but they cannot harness this information in the service of action, and this is said to show that a function of phenomenal consciousness is somehow to enable information represented in the brain to guide action. But stimuli in the blind field are BOTH access-unconscious and phenomenally unconscious. The fallacy is: an obvious function of the machinery of access-consciousness is illicitly transferred to phenomenal consciousness. (shrink)

The explanatory gap and theknowledge argument are rooted in the conflationof propositional and phenomenal knowledge. Thebasic knowledge argument is based on theconsideration that ``physical information'' aboutthe nervous system is unable to provide theknowledge of a ``color experience'' . The implication is that physicalism isincomplete or false because it leaves somethingunexplained. The problem with Jackson'sargument is that physical information has theform of highly symbolic propositional knowledgewhereas phenomenal knowledge consists in innateneurophysiological processes. In addition totheir fundamental epistemological differences,clinical, anatomical, pathological and brainimaging (...) studies demonstrate that phenomenal andpropositional knowledge are fundamentallydifferent neurobiological processes. Propositional knowledge is phylogeneticallynew, highly symbolic, culturally acquired,exclusively human and expressible in differentnatural and artificial languages. By contrast,phenomenal knowledge consists inqualitative experiences and phenomenal conceptsthat provide an internal, language-independentreference to the properties of objects and theneeds of the organism. Language andpropositional knowledge are exclusively humanattributes implemented in specific regions ofthe dominant hemisphere. This contrastssharply with the phylogenicallysensory areas that are common to animals andhumans, which implement qualitativeexperiences. Experiences are hard-wiredneurobiological processes that can neither betransmitted nor re-created through thesymbolism of propositions. Thus, I concludethat the fallacy in the explanatory gap and inthe knowledge argument is a fallacy ofequivocation that results from ignoringfundamental neurobiological differences betweenphenomenal and propositional knowledge.

Through this contribution I aim to explore the horizons and limits of digital medicine in light of an embodied approach to the issue of care. I will sketch the historical background of digital medicine and show the contemporary status of this interdisciplinary field, as well as its applications and outcomes. Then, I will address a critique of the computational theory of mind (CTM) upon which many contemporary mental health apps are designed. This approach to the mind is inscribed into the (...) modern trend of neuromania, which conceives the embodied, living human being as a mere series of data analyses and algorithms, with the brain as the seat of the person. Drawing on continental philosophy and classical phenomenology I will develop a notion of health conceived as a moral enterprise, showing how wellbeing and vitality are not reducible to a product made by technologies or doctors, but rather they are the results of an embodied encounter. As such, empathy and person-centered care cannot be achieved by digital medicine. They are the result of a journey into the regions of recognition, embodied presence and the aliveness constituting the person. Finally, I will show how the issue of care cannot be separated from an embodied encounter between people, especially in case of dementia. (shrink)

If we have libertarian free will, then it is plausible to believe that the occurrences of certain physical events have irreducible and ineliminable mental explanations. According to a strong version of naturalism, everything in the physical world is in principle explicable in nonmental terms. Therefore, the truth of naturalism implies that libertarian choices cannot explain the occurrences of any physical events. In this paper, I example a methodological argument for the truth of naturalism and conclude that the argument fails. I (...) then consider additional concerns raised against the reality of libertarian freedom. First, I examine the claim that if a physical event E is not causally determined to occur by another physical event, then there is no way to account for the difference between E’s occurring randomly and E’s being causally determined to occur by a mental event. Second, I consider the assertion that the affirmation of libertarianism is a mind-of-the-gaps version of the God-of-the-gaps objection to a divine explanation of a physical event. Third, I take up the question of whether the inability of libertarians to pinpoint precisely where the initial physical effects of libertarian choices occur is a good reason for rejecting libertarianism. Fourth, I examine the claim that belief in the existence of the soul or immaterial mind is the result of an explanatory hypothesis to account for how libertarian free choices can causally produce physical effects. Fifth, I look at the traditional objection to substance dualism from the impossibility of causal interaction between a soul and its body. (shrink)

The biological Brain createst the mental Mind. Today our collective Mind becomes so fascinated by its source, the Brain, that all sciences incorporate neuro models in their concepts to increase global brainpower with technology. The most significant discovery is probably technology. We learn how the Brain creates consciousness and how the Brain generates momentaneous Time. Discover how at each moment in Time, our body runs the whole program of Evolution. What we know about the Brain is phantasy from the Mind.

Neurophilosophy is a controversial scientific discipline lacking a broadly accepted definition and especially a well-elaborated methodology. Views about what neurophilosophy entails and how it can combine neuroscience with philosophy, as in their branches and methodologies, diverge widely. This article, first of all, presents a brief insight into the naturalization of philosophy regarding neurophilosophy and three resulting distinguishable forms of how neuroscience and philosophy may or may not be connected in part 1, namely reductive neurophilosophy, the parallelism between neuroscience and philosophy (...) which keeps both disciplines rather strictly separated and lastly, non-reductive neurophilosophy which aims for a bidirectional connection of both disciplines. Part 2 presents a paradigmatic example of how these three forms of neuroscience and philosophy approach the problem of self, mainly concerning its ontological status. This allows me to compare all three neurophilosophical approaches with each other and to highlight the benefits of a non-reductive form of neurophilosophy. I conclude that especially non-reductive neurophilosophy can give full justice to the complementary position of neurophilosophy right at the intersection between neuroscience, philosophy, and psychology.

It is intuitive that free action depends on consciousness in some way, since behavior that is unconsciously generated is widely regarded as un-free. But there is no clear consensus as to what such dependence comes to, in part because there is no clear consensus about either the cognitive role of consciousness or about the essential components of free action. I divide the space of possible views into four: the Constitution View (on which free actions metaphysically consist, at least in part, (...) in phenomenally conscious episodes of a special sort), the Causal-Dependence View (on which free actions are necessarily caused by conscious episodes), the Counterfactaul-Dependence View (on which free actions necessarily counterfactually dependent on conscious episodes of certain types), and the Independence View (on which there are no necessary dependence-relations that hold between free action and conscious episodes). After surveying recent empirical literature that purports to show that consciousness plays a smaller role in generating action than is usually supposed, I conclude that it is plausible that free action depends on consciousness in two ways. First, free action causally depends on consciousness control. Second, free action counterfactually depends on the agent's being responsive to certain reasons. (shrink)

This article provides a critical examination of a controversial issue that has theoretical and practical importance to a broad range of academic disciplines: Are religious experiences localized within the brain? Research into the neuroscience of religious experiences is reviewed and conceptual and methodological challenges accompanying the neurotheology project of localizing religious experiences within the brain are discussed. An alternative theory to current reductive and mechanistic explanations of observed mind–brain correlations is proposed — a mediation theory of cerebral action — that (...) has the potential for addressing what Chalmers called the “hard problem” of consciousness.

Because the mind is the significance of the brain and God is the significance of the mind, the concept “mind” bridges how the brain works and traditional patterns of belief. The left mind, which utilizes rational vigilance and the imperative instructions of proclamation, names and analyzes the urgently right. The right mind, which discloses the relational responsiveness of numinous presence and natural symbolism, is immersed in and integrates the ultimately real. Together they provide a typology of mind‐states with which to (...) assess regressive, functional, and creative patterns. Hand dominance, gender differences, and cultural bias qualify the use of the metaphor. (shrink)

What are actions? And how are actions to be explained? These two central questions of the philosophy of action call, respectively, for a theory of the nature of action and a theory of the explanation of actions. Many ordinary explanations of actions are offered in terms of such mental states as beliefs, desires, and intentions, and some also appeal to traits of character and emotions. Traditionally, philosophers have used and refined this vocabulary in producing theories of the explanation of intentional (...) actions. An underlying presupposition is that common-sense explanations expressed in these terms have proved very useful. People understand their own and others' actions well enough to coordinate and sustain complicated, cooperative activities integral to normal human life, and that understanding is expressed largely in a common-sense psychological vocabulary. This article focuses on these issues. (shrink)

In this article first some general aspects of near-death experience will be discussed, followed by questions about consciousness and its relation to brain function. Details will be described from our prospective study on near-death experience in survivors of cardiac arrest in the Netherlands, which was published in the Lancet in 2001. In this study it could not be shown that physiological, psychological, or pharmacological factors caused these experiences after cardiac arrest. Neurophysiology in cardiac arrest and in a normal functioning brain (...) will be explained. Finally, implications for consciousness studies will be discussed, and how it could be possible to explain the continuity of our consciousness. Scientific study of NDE pushes us to the limits of our medical and neurophysiologic ideas about the range of human consciousness and mind-brain relation. (shrink)

I argue that in order to solve the main difficulties confronted by the classical versions of the causal theory of action, it is necessary no just to make room for intentions, considered as irreducible to complexes of beliefs and desires, but also to distinguish among several types of intentions. I present a three-tiered theory of intentions that distinguishes among future-directed intentions, present-directed intentions and motor intentions. I characterize each kind of intention in terms of its functions, its type of content, (...) its dynamics and the rationality and time constraints that bear on it. I then try to show how the difficulties encountered by the causal theory can be solved within this new framework. 1. (shrink)

In this paper, I argue that the conscious awareness one has of oneself as acting, i.e., agentive awareness, is not a type of sensory awareness. After providing some set up in Sect. 1, I move on in Sect. 2 to sketch a profile of sensory agentive experiences as representational states with sensory qualities by which we come to be aware of ourselves as performing actions. In Sect. 3, I critique two leading arguments in favor of positing such sensory experiences: the (...) argument from pathology and the argument from cognitive impenetrability. Since neither of these arguments succeeds, the case for positing SAEs is dealt a significant blow. I proceed in Sect. 4 to advance my positive argument against SAEs. The argument runs as follows: If SAEs exist, then they must exist in some sensory modality or set of sensory modalities. Either the relevant sensory modalities are ones that we already recognize, or they are novel sensory modalities. I will argue that neither of these options is workable, and so we have nowhere to locate SAEs. Agentive awareness is not sensory awareness. (shrink)

Como encontrar conteúdo filosófico confiável em meio a milhares de artigos publicados diariamente na internet? Para ir ainda mais longe, como encontrar uma introdução a algum tópico com uma lista de referências bibliográficas atualizadas e que seja organizada por um especialista da área? Já que você começou a ler este livro, é provável que tenha ouvido (...) falar em algum momento da Enciclopédia Stanford de Filosofia, disponível gratuitamente na internet desde 1995. A página da Stanford faz exatamente isso.

A sugestão típica aos profissionais da filosofia que têm interesse em começar a estudar algum tópico, mas não sabem sequer por onde começar, é procurar pelo verbete relevante da Stanford. Infelizmente, o grande empecilho da página para o nosso contexto é que todos os verbetes estão disponíveis apenas em inglês, algo que cria um obstáculo a inúmeros estudantes e interessados que não dominam a língua.

Embora a filosofia no Brasil tenha se profissionalizado e expandido ao longo dos anos, há ainda lacunas em diversas áreas, e os verbetes foram aqui selecionados cuidadosamente no intuito de preencher ao menos algumas dessas lacunas. Este livro apresenta quatro verbetes cruciais para a filosofia, aqui divididos em quatro capítulos: (1) condições necessárias e suficientes, (2) referência (3) causação e (4) consciência. (shrink)

Western philosophy and science have a strongly dualistic tradition regarding the mental and physical aspects of reality, which makes it difficult to understand their possible causal relations. In recent debates in cognitive neuroscience it has been common to claim on the basis of neural experiments that conscious experiences are causally inefficacious. At the same time there is much evidence that consciousness does play an important role in guiding behavior. The author explores whether a new way of understanding the causal role (...) of mental states and consciousness could be provided by the ontological interpretation of the quantum theory (Bohm and Hiley, Phys. Rep. 144:323–348, 1987; Bohm and Hiley, The undivided universe: An ontological interpretation of quantum theory. Routledge: London, 1993). This interpretation radically changes our notion of matter by suggesting that a new type of active information plays a causal role at the quantum level of reality. The author thus considers to what extent the alleged causal powers of consciousness involve information, and then moves on to consider whether information in (conscious) mental states can be connected to the information at the level of quantum physics. In this way he sketches how quantum theory might help to throw light upon one of the grand challenges facing the social sciences and the humanities, namely the question of whether consciousness plays any genuine causal role in the physical world.

This paper, Part III of a critique of survivalist interpretations of near-death experiences (NDEs), considers psychophysiological and cultural correlates of NDEs suggesting that such experiences are solely products of individuals' minds rather than windows into a transcendental realm. While current psychophysiological models do not fully explain out-of-body experiences (OBEs) and NDEs, several psychophysiological correlates offer promising clues about the mechanisms implicated in their production. These correlates do not definitively identify their precise causes, but strongly imply that such experiences represent internally (...) generated fantasies rather than genuine perceptions of a transcendental environment. Additionally, stark differences in the phenomenology of NDEs from different cultures have been uncovered. Though nonWestern samples are too limited to draw anything more than tentative conclusions, the available data suggest that prototypical Western NDE motifs derive from a cultural source, consistent with the hypothesis that NDE content reflects social conditioning and personal expectation rather than the perception of an external reality.

The world’s major monotheistic religions typically maintain that God freely chose, in the libertarian sense, to create the universe for a reason or purpose. Philosophers of religion often argue that the idea that God makes a free choice to create for a purpose is deeply flawed. In parallel with these philosophers of religion, philosophers of action typically argue that the idea that human beings make free choices to act for purposes is also flawed. I begin my article by briefly summarizing (...) what is involved in the idea of a human agent freely choosing for a purpose. I then examine criticisms of this idea by philosophers of action and suggest how they might plausibly be rebutted. I conclude by suggesting that if these criticisms by philosophers of action are suspect, then there is good reason for thinking that the same or similar criticisms by philosophers of religion are suspect.

Dualist and Reductionist theories of mind disagree about whether or not consciousness can be reduced to a state of or function of the brain. They assume, however, that the contents of consciousness are separate from the external physical world as-perceived. According to the present paper this assumption has no foundation either in everyday experience or in science. Drawing on evidence for perceptual projection in both interoceptive and exteroceptive sense modalities, the case is made that the physical world as-perceived is a (...) construct of perceptual processing and, therefore, part of the contents of consciousness. A finding which requires a Reflexive rather than a Dualist or Reductionist model of how consciousness relates to the brain and the physical world. The physical world as-perceived may, in turn be thought of as a biologically useful model of the world as described by physics. Redrawing the boundaries of consciousness to include the physical world as-perceived undermines the conventional separation of the 'mental' from the physical', and with it the very foundation of the Dualist-Reductionist debate. The alternative Reflexive model departs radically from current conventions, with consequences for many aspects of consciousness theory and research. Some of the consequences which bear on the internal consistency and intuitive plausibility of the model are explored, e.g. the causal sequence in perception, representationalism, a suggested resolution of the Realism versus Idealism debate, and the way manifest differences between physical events as-perceived and other conscious events are to be construed. In the present paper I wish to challenge some of our most deeply-rooted assumptions about what consciousness is, by re-examining how consciousness, the human brain, and the surrounding physical world relate to each other.

In this commentary, I critically assess Rex Welshon’s position on the neural substrates of ownership unity. First, I comment on Welshon’s definition of ownership unity and underline some of the problems stemming from his phenomenological analysis. Second, I analyze Welshon’s proposal to establish a mechanistic relation between neural substrates and ownership unity. I show that it is insufficient and defend my own position on how neural mechanisms may give rise to whole subjects of experience, which I call the neuro-integrative account (...) of consciousness. Lastly, I comment on Welshon’s philosophical contribution and claim that it leaves the reader theoretically stranded. (shrink)

This paper explores the suggestion that our conscious experience is embodied in, rather than interactive with, our brain activity, and that the distinctive brain correlate of conscious experience lies at the level of global functional organization. To speak of either brains or computers as thinking is categorically inept, but whether stochastic mechanisms using internal experimentation rather than rule‐following to determine behavior could embody conscious agency is argued to be an open question, even in light of the Christian doctrine of man. (...) Mechanistic brain science does nothing to discredit Christian experience in dialogue with God or the Christian hope of eternal life. (shrink)

In a recent Zygon article (June 1991), Roger Sperry argues for the unification of science and religion based on the principle of emergent causation within the central nervous system. After illustrating Sperry's position with some current experiments, I suggest that his conclusions exceed his argument and the findings of contemporary neuroscience and propose instead a pluralistic, rather than unified, approach to the relations between religion and science necessitated by the incompleteness inherent in any strictly neurological account of human nature.
