Of all the problems facing science none are more challenging yet fascinating than those posed by consciousness. In The Science of Consciousness leading researchers examine how consciousness is being investigated in the key areas of cognitive psychology, neuropsychology and clinical psychology. Within cognitive psychology, special focus is given to the function of consciousness, and to the relation of conscious processing to nonconscious processing in perception, learning, memory and information dissemination. Neuropsychology includes examination of the neural conditions for consciousness and the effects of brain damage. Finally, mind/body interactions in clinical and experimental settings are considered, including the somatic effects of imagery, biofeedback and placebo effects. Every chapter is written by an expert in the field. They each provide a clear overview of existing research along with an exciting new synthesis of consciousness studies. The The Science of Consciousness will be invaluable for students, researchers and clinicians interested in the developments and directions of this rapidly growing field

(added for 2013 upload): This chapter compares classical dualist and reductionist views of phenomenal consciousness with an alternative, reflexive way of viewing the relations amongst consciousness, brain and the external physical world. It argues that dualism splits the universe in two fundamental ways: in viewing phenomenal consciousness as having neither location nor extension it splits consciousness from the material world, and subject from object. Materialist reductionism views consciousness as a brain state or function (located and extended in the brain) which eliminates the consciousness/material world split, but retains the split of subject from object. The chapter argues that neither dualism nor reductionism accurately describes the phenomenal world; consequently they each provide a misleading understanding of phenomenal consciousness. Reflexive monism follows the contours of everyday experience, thereby allowing a more unified understanding of how phenomenal consciousness relates to the brain and external physical world that is consistent both with the findings of science and with common sense. The chapter goes on to consider how phenomenal objects relate to real objects, perceptual projection, how phenomenal space relates to physical space, whether the brain is in the world or the world in the brain, and why this matters for science.

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

This paper provides an initial, multidimensional map of the complex relationships among consciousness, mind, brain, and the external world in a way that both follows the contours of everyday experience and the findings of science. It then demonstrates how this reflexive monist map can be used to evaluate the utility and resolve some of the oppositions of the many other 'isms' that currently populate consciousness studies. While no conventional, one-dimensional 'ism' such as physicalism can do justice to this web of relationships, physicalism, functionalism, dualism, neutral monism, and dual-aspect monism can all be seen to provide useful ways of understanding different aspects of the relationships among consciousness, mind, brain, and the external world when these are viewed in either a first- or a third-person way from within this web of relationships by sentient creatures such as ourselves. For example, physicalism and functionalism provide a useful understanding of consciousness, mind, brain, and the external world when viewed from a third-person perspective, while neutral monism provides a useful way of understanding first- versus third-person views of external phenomena. On the other hand, dual-aspect monism provides a useful way of understanding first- versus third-person views of mind, including eastern versus western views of mind. Dual-aspect monism also provides a useful understanding of the 'unconscious ground of being' that gives rise to, supports, and embeds all these observable phenomena. For an integrated understanding one needs to understand how these phenomena and relationships combine into an integrated whole.

This is a prepublication version of the final chapter from the Blackwell Companion to Consciousness. In it I re-examine the basic conditions required for a study of conscious experiences in the light of progress made in recent years in the field of consciousness studies. I argue that neither dualist nor reductionist assumptions about subjectivity versus objectivity and the privacy of experience versus the public nature of scientific observations allow an adequate understanding of how studies of consciousness actually proceed. The chapter examines the sense in which the experimenter is also a subject, the sense in which all experienced phenomena are private and subjective, the different senses in which a phenomenon can nevertheless be public and observations of it objective, and the conditions for intra-subjective and intersubjective repeatability. The chapter goes on to re-examine the empirical method and how methods used in psychology differ from those used in physics. I argue that a reflexive understanding of these relationships supports a form of “critical phenomenology” that fits consciousness studies smoothly into science

Les théories de l’évolution de la conscience sont étroitement liées aux théories de la distribution de la conscience qui vont des approches considérant que seulement l’homme a une conscience jusqu’aux approches considérant que toute matière possède une conscience en quelque sorte. De manière générale, on peut distinguer les théories de la discontinuité des théories de la continuité. Les théories de la discontinuité considèrent que la conscience est apparue seulement une fois que les formes matérielles ont atteint un certain degré d’évolution mais proposent des critères différents lorsqu’il s’agit de déterminer le degré en question. Les théories de la continuité soutiennent que, dans une certaine forme primaire, la conscience accompagne toujours la matière et tandis que celle-ci a évolué vers la forme, la complexité de la conscience a co-évolué avec elle, vers par exemple des formes que nous reconnaissons actuellement chez les êtres humains. Etant donnée notre connaissance limitée des conditions suffisantes et nécessaires à la présence de la conscience chez les êtres humains, toutes les options restent ouvertes. Tout compte fait, la théorie de la continuité paraît plus élégante que la théorie de la discontinuité

How can one investigate phenomenal consciousness? As in other areas of science, the investigation of consciousness aims for a more precise knowledge of its phenomena, and the discovery of general truths about their nature. This requires the development of appropriate first-person, second-person and third-person methods. This book introduces some of the creative ways in which these methods can be applied to different purposes, e.g. to understanding the relation of consciousness to brain, to examining or changing consciousness as such, and to understanding the way consciousness is influenced by social, clinical and therapeutic contexts. To clarify the strengths and weaknesses of different methods and to demonstrate the interplay of methodology and epistemology, the book also suggests a number of “maps” of the consciousness studies terrain that place different approaches to the study of consciousness into a broader, interdisciplinary context.

Wegner’s analysis of the illusion of conscious will is close to my own account of how conscious experiences relate to brain processes. But our analyses differ somewhat on how conscious will is not an illusion. Wegner argues that once conscious will arises it enters causally into subsequent mental processing. I argue that while his causal story is accurate, it remains a first-person story. Conscious free will is not an illusion in the sense that this first-person story is compatible with and complementary to a third-person account of voluntary processing in the mind/brain.

What we normally think of as the “physical world” is also the world as experienced, that is, a world of appearances. Given this, what is the reality behind the appearances, and what might its relation be to consciousness and to constructive processes in the mind? According to Kant, the thing itself that brings about and supports these appearances is unknowable and we can never gain any understanding of how it brings such appearances about. Reflexive monism argues the opposite: the thing itself is knowable as are the processes that construct conscious appearances. Conscious appearances (empirical evidence) and the theories derived from them can represent what the world is really like, even though such empirical knowledge is partial, approximate and uncertain, and conscious appearances are species-specific constructions of the human mind. Drawing on the writings of Husserl, Hoche suggests that problems of knowledge, mind and consciousness are better understood in terms of a “pure noematic” phenomenology that avoids any reference to a “thing itself.” I argue that avoiding reference to a knowable reality (behind appearances) leads to more complex explanations with less explanatory value and counterintuitive conclusions—for example Hoche’s conclusion that consciousness is not part of nature. The critical realism adopted by reflexive monism appears to be more useful, as well as being consistent with science and common sense.

There have been various attempts to apply Darwinian evolutionary theory to an understanding of the human condition within psychology and the social sciences. This paper evaluates whether Darwinian Theory can explain human consciousness. Starting with a brief definition of phenomenal consciousness and the central features of evolutionary theory, the paper examines whether random variations in the genome that confer a selective, reproductive advantage can explain both the emergence of consciousness and its varied forms. To inform the discussion, the paper reviews what is known about the conditions for consciousness within the human mind/brain, understood in both structural (neural) terms and functional terms (in terms of human information processing), and concludes that “random variations in the genome” provide no explanatory mechanism for why some neural activities (but not others) are accompanied by consciousness. The paper then evaluates the many functional advantages that have been proposed for various forms of phenomenal consciousness once they emerge, and concludes that, on close examination, phenomenal experiences themselves do not carry out the information processing functions attributed to them, which challenges the Darwinian requirement that they could only have persisted (once emergent) it they enhanced reproductive fitness. The paper turns finally to what can be said about wider distribution of consciousness in non-humans, contrasting discontinuity theories with continuity theories. Discontinuity theories argue for a critical functional transition that “switches on consciousness” while continuity theories argue for a gradual transition in consciousness from unrecognisable to recognisable. All theories accept that there is an intimate, natural relationship of conscious experiences with their associated material forms. Consequently, as the material forms evolve, their associated experiences co-evolve—suggesting an indirect mechanism by which the emergence of species-specific forms of consciousness can be influenced by Darwinian evolution. It also allows a non-reductive understanding of human consciousness within the social sciences.

This paper evaluates Mangan’s (1993) analysis of the way feelings at the fringes of consciousness provide global evaluations of what is happening at the focus of attention in ways that allow the human mind to direct its activities in an effective, adaptive way—elaborating on a distinction between fringe consciousness and focal-attentive consciousness originally developed by William James. The paper argues that, while Mangan’s analysis is a plausible account of mental operations, viewed from a first-person perspective, it is inconsistent with a detailed account of human information processing viewed from a third-person perspective, which largely operates in an unconscious fashion. It also ignores classical problems relating to consciousness-brain causal interaction in philosophy of mind, and the subtlety different ways in which information processing can be said to be “conscious”. The paper then offers an alternative interpretation of the evidence (following Velmans, 1991) in which first- and third-person accounts of mental processing are complementary and mutually irreducible.

There are two quite distinct ways in which events that we normally think of as “physical” relate in an intimate way to events that we normally think of as “psychological”. One intimate relation occurs in exteroception at the point where events in the world become events as-perceived. The other intimate relationship occurs at the interface of conscious experience with its neural correlates in the brain. The chapter examines each of these relationships and positions them within a dual-aspect, reflexive model of how consciousness relates to the brain and external world. The chapter goes on to provide grounds for viewing mind and nature as fundamentally psychophysical, and examines similar views as well as differences in previously unpublished writings of Wolfgang Pauli, one of the founders of quantum mechanics.

This Introduction to a Journal of Consciousness Studies Special Issue on Monist Alternatives to Physicalism summarises some of the basic problems of Physicalism and common fallacies in arguments for its defence that are found in the philosophical and scientific literature. It then introduces six monist alternatives: 1) a form of emergent panpsychism developed by William Seager; 2) a novel introduction to the process philosophy of A.N. Whitehead by Anderson Weekes; 3) a review of current developments in Russellian Monism by Torin Alter and Yujin Nagasawa; 4) an analysis of dual-aspect monism and its relation to quantum mechanics originally proposed developed by Pauli and Jung and given a modern interpretation by Harald Atmanspacher; 5) a form of processing monism that might help to resolve ontological differences in Indian philosophy and psychology between dualist Samkya Yoga and nondualist Advaita Vedanta by K. Ramakrisna Rao; and 6) an account of Reflexive Monism, which, viewed as a global system, can incorporate many of the seemingly opposed “isms” that currently populate Consciousness Studies by Max Velmans. Whatever the fundamental nature of Nature might be, it must have the power to give rise to its observable manifestations. Consequently, all the papers in this issue are concerned to give a “natural” account of the relationships among consciousness, mind, and the material world that is entirely consistent with the findings of science, and they all accept that for a unified understanding, mind, consciousness and the material world must have a common base. The aim of the Special Issue is to contribute to a deeper understanding of that base, and to stimulate novel thinking about its nature.

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.

This paper summarised the main arguments presented in "Consciousness, brain and the physical world" Philosophical Psychology (1990) to introduce a symposium on that paper. This was the first symposium on Velmans' Reflexive Model of Perception (the departure point for Reflexive Monism). This summary of the 1990 paper was followed by three critiques (by Robert Rentoul, Norman Wetherick, and Grant Gillett) followed by two replies. At the time of this upload (25 years later) many of the points in the 1991 paper have become common currency, however some of the confusions about the implications of the reflexive model persist, so the discussion continues to have contemporary relevance. See academia.edu link for the entire symposium.

To understand consciousness we must first describe what we experience accurately. But oddly, current dualist vs reductionist debates characterise experience in ways which do not correspond to ordinary experience. Indeed, there is no other area of enquiry where the phenomenon to be studied has been so systematically misdescribed. Given this, it is hardly surprising that progress towards understanding the nature of consciousness has been limited. This chapter argues that dualist vs. reductionist debates adopt an implicit description of consciousness that does not resemble ordinary experience. If one adopts an accurate description of conscious phenomenology along with an understanding of the fundamental differences between correlation, causation and ontological identity, reductionism cannot succeed. However the alternative is not a dualism that places consciousness beyond science. Rather, it is a nonreductionist science of consciousness.

This reply to five continuing commentaries on my 1991 target article on “Is human information processing conscious” focuses on six related issues: 1) whether focal attentive processing replaces consciousness as a causal agent in third-person viewable human information processing, 2)whether consciousness can be dissociated from human information processing, 3) continuing disputes about definitions of "consciousness" and about what constitutes a “conscious process” , 4) how observer-relativity in psychology relates (and does not relate) to relativity in physics, 5) whether the first-person viewable causal efficacy of consciousness counts as ‘real’ causal efficacy and 6) a clarification of the sense in which first- and third-person causal accounts of mental processing are complementary and mutually irreducible

This reply appeared in a symposium on "Consciousness and the Physical World" published in Philosophical Psychology in 1992.This was the first symposium on Velmans' Reflexive Model of Perception (the departure point for Reflexive Monism) initially presented in "Consciousness, Brain and the Physical World" (1990) also in Philosophical Psychology. The symposium begins with Velmans' summary of the main arguments in that paper, followed by critiques from two psychologists--Robert Rentoul and Norman Wetherick. Velmans replies to the critiques and the entire treatment is further critiqued by the philosopher Grant Gillett, followed by Velmans' final reply. At the time of this upload (25 years later) many of the points in the original paper have become common currency, however some of the confusions about the implications of the reflexive model persist, so the discussion continues to have contemporary relevance.

This overview of Consciousness Studies examines the conditions that one has to satisfy to establish a scientific investigation of phenomenal consciousness. Written from the perspective experimental psychology, it follows a two-pronged approach in which traditional third-person methods for investigating the brain and physical world are complementary to first-person methods for investigating subjective experience allowing the possibility of finding “bridging laws” that relate such first- and third-person data to each other. Mindful of the relative sophistication of third-person methods the chapter focuses on the problems of developing similarly sophisticated first-person methods. The problems are of three kinds: (1) Epistemological problems: How can one obtain public, objective knowledge about private, subjective experiences? (2) Methodological problems: Given that one cannot attach measuring instruments directly up to experiences, what psychological “instruments” and procedures are appropriate to their study? (3) The relation of the observer to the observed: The more closely coupled an observer is with an observed, the greater the potential influence of the act of observation on the nature of the observed (“observer effects”). Given this, how can one develop introspective and phenomenological methods where the observer is the observed? The chapter argues that the epistemological problems are more apparent than real, although this requires one to construe what is private versus public, and what is subjective or intersubjective versus what is objective in a slightly different way—with some enabling consequences for a science of consciousness. Methodological problems are real, but not fundamentally different to the problems traditionally faced in experimental psychological investigations of mental phenomena. The close-coupling of observer with the observed in first-person investigations can also be a problem, producing “observer effects” that are more acute than in most third-person investigations. The chapter suggests that one can either try to minimise such effects or to harness them, depending on the purpose of the investigation.

My target article (henceforth referred to as TA) presents evidence for causal interactions between consciousness and brain and some standard ways of accounting for this evidence in clinical practice and neuropsychological theory. I also point out some of the problems of understanding such causal interactions that are not addressed by standard explanations. Most of the residual problems have to do with how to cross the “explanatory gap” from consciousness to brain. I then list some of the reasons why the route across this gap suggested by physicalism won't work, in spite of its current popularity in consciousness studies. My own suggested route across the explanatory gap is more subterranean, where consciousness and brain can be seen to be dual aspects of a unifying, psychophysical mind. Some of the steps on this deeper route still have to be filled in by empirical research. But (as far as I can judge) there are no gaps that cannot be filled—just a different way of understanding consciousness, mind, brain and their causal interaction, with some interesting consequences for our understanding of free will. The commentaries on TA examined many aspects of my thesis viewed from both Western and Eastern perspectives. This reply focuses on how dual-aspect monism compares with currently popular alternatives such as “nonreductive physicalism”, clarifies my own approach, and reconsiders how well this addresses the “hard” problems of consciousness. We re-examine how conscious experiences relate to their physical/functional correlates and whether useful analogies can be drawn with other, physical relationships that appear to have dual-aspects. We also examine some fundamental differences between Western and Eastern thought about whether the existence of the physical world or the existence of consciousness can be taken for granted (with consequential differences about which of these is “hard” to understand). I then suggest a form of dual-aspect Reflexive Monism that might provide a path between these ancient intellectual traditions that is consistent with science and with common sense.

How can one investigate phenomenal consciousness? As in other areas of science, the investigation of consciousness aims for a more precise knowledge of its phenomena, and the discovery of general truths about their nature. This requires the development of appropriate first-person, second-person, and third-person methods. This book introduces some of the creative ways in which these methods can be applied to different purposes, e.g. to understand the relation of consciousness to brain, to examining or changing consciousness as such, and to the way consciousness is influenced by social, clinical and therapeutic contexts. To clarify the strengths and weaknesses of different methods and to demonstrate the interplay of methodology and epistemology, the book also suggests a number of "maps" of the consciousness studies terrain that places different approaches to the study of consciousness into a broader, interdisciplinary context.

Dualists believe that experiences have neither location nor extension, while reductive and ‘non-reductive’ physicalists (biological naturalists) believe that experiences are really in the brain, producing an apparent impasse in current theories of mind. Enactive and reflexive models of perception try to resolve this impasse with a form of “externalism” that challenges the assumption that experiences must either be nowhere or in the brain. However, they are externalist in very different ways. Insofar as they locate experiences anywhere, enactive models locate conscious phenomenology in the dynamic interaction of organisms with the external world, and in some versions, they reduce conscious phenomenology to such interactions, in the hope that this will resolve the hard problem of consciousness. The reflexive model accepts that experiences of the world result from dynamic organism–environment interactions, but argues that such interactions are preconscious. While the resulting phenomenal world is a consequence of such interactions, it cannot be reduced to them. The reflexive model is externalist in its claim that this external phenomenal world, which we normally think of as the “physical world,” is literally outside the brain. Furthermore, there are no added conscious experiences of the external world inside the brain. In the present paper I present the case for the enactive and reflexive alternatives to more classical views and evaluate their consequences. I argue that, in closing the gap between the phenomenal world and what we normally think of as the physical world, the reflexive model resolves one facet of the hard problem of consciousness. Conversely, while enactive models have useful things to say about percept formation and representation, they fail to address the hard problem of consciousness

Modern consciousness studies are in a healthy state, with many progressive empirical programmes in cognitive science, neuroscience and related sciences, using relatively conventional third-person research methods. However not all the problems of consciousness can be resolved in this way. These problems may be grouped into problems that require empirical advance, those that require theoretical advance, and those that require a re-examination of some of our pre-theoretical assumptions. I give examples of these, and focus on two problems—what consciousness is, and what consciousness does—that require all three. In this, careful attention to conscious phenomenology and finding an appropriate way to relate first-person evidence to third-person evidence appears to be central to progress. But we may also need to re-examine what we take to be “natural facts” about the world, and how we can know them. The same appears to be true for a trans-cultural understanding of consciousness that combines classical Indian phenomenological methods with the third-person methods of Western science.

This commentary elaborates on Gray's conclusion that his neurophysiological model of consciousness might explain how consciousness arises from the brain, but does not address how consciousness evolved, affects behaviour or confers survival value. The commentary argues that such limitations apply to all neurophysiological or other third-person perspective models. To approach such questions the first-person nature of consciousness needs to be taken seriously in combination with third-person models of the brain.

Viewed from a first-person perspective consciousness appears to be necessary for complex, novel human activity - but viewed from a third-person perspective consciousness appears to play no role in the activity of brains, producing a "causal paradox". To resolve this paradox one needs to distinguish consciousness of processing from consciousness accompanying processing or causing processing. Accounts of consciousness/brain causal interactions switch between first- and third-person perspectives. However, epistemically, the differences between first- and third-person access are fundamental. First- and third-person accounts are complementary and mutually irreducible.

This chapter examines the similarities and differences between physical, psychological and virtual realities, and challenges some conventional, implicitly dualist assumptions about how these relate to each other. Virtual realities are not easily understood in either dualist or materialist reductive terms, as they exemplify the reflexive nature of perception. The chapter summarises some of the evidence for this “reflexive model”—and examines some of its consequences for the “hard” problem of consciousness. The chapter then goes on to consider how these realities might relate to some grounding reality or thing-itself, and considers some of the personal and social consequences of becoming increasingly immersed in virtual realities. Although this chapter was published in 1998 and develops work published in 1990, it presents a form of “radical externalism” that anticipates many themes in current (2006) internalism versus externalism debates about the nature of mind. It is also relevant to an understanding of virtual reality “presence.”

Nature Network Groups hosted an invited workshop on 'Theories of Consciousness' during the second semester of 2009. There were presentations by each of 15 authors active in the field, followed by debate with other presenters and invitees. A week was allocated to each of the theories proposed; general discussion threads were also opened from time to time, as seemed appropriate. We offer here an account of the principal outcomes. It can be regarded as a contemporary, 'state of the art' snapshot of thinking in this field.
