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mind and nature as fundamentally psychophysical, and examines similar views as well as differences in previously unpublished writings of Wolfgang Pauli, one of the founders of quantum mechanics.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.

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 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.

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.

Abstract. This introductory chapter was written in 1996, for a new book of review articles on the emerging science of consciousness, specifically aimed at undergraduate and postgraduate students by experts in the relevant fields. Following on a brief history, the chapter moves on to definitions of consciousness and background philosophical issues, and then introduces a unified, non-reductionist scientific approach. It then summarises major issues for studies of consciousness in cognitive psychology, including studies of attention, memory, the extent of preconscious analysis and the relation of consciousness more generally to human information processing. It then turns to the neuropsychology of consciousness, starting with some apparent neural requirements for the transition from preconscious to conscious states, various clinical dissociations of consciousness, conditions for integration (or binding) and, finally, clinical applications, including different forms of mind/body interaction and evidence for the causal efficacy of mental states. The chapter concludes that while some of the ancient problems of consciousness remain unsolved, its study has become the subject of a rapidly developing science.

Investigations of the function of consciousness in human information processing have focused mainly on two questions: (1) where does consciousness enter into the information processing sequence and (2) how does conscious processing differ from preconscious and unconscious processing. Input analysis is thought to be initially "preconscious," "pre-attentive," fast, involuntary, and automatic. This is followed by "conscious," "focal-attentive" analysis which is relatively slow, voluntary, and flexible. It is thought that simple, familiar stimuli can be identified preconsciously, but conscious processing is needed to identify complex, novel stimuli. Conscious processing has also been thought to be necessary for choice, learning and memory, and the organization of complex, novel responses, particularly those requiring planning, reflection, or creativity.

The mysteries of consciousness have gripped the human imagination for over 2,500 years. At the dawn of the new millennium, Understanding Consciousness provides new solutions to some of the deepest puzzles surrounding its nature and function. Drawing on recent scientific discoveries, Max Velmans challenges conventional reductionist thought, providing an understanding of how consciousness relates to the brain and physical world that is neither dualist, nor reductionist. Understanding Consciousness will be of great interest to psychologists, philosophers, neuroscientists and other professionals concerned with mind/body relationships, and all who care deeply about this subject.

In everyday life we take it for granted that we have conscious control of some of our actions and that the part of us that exercises control is the conscious mind. Psychosomatic medicine also assumes that the conscious mind can affect body states, and this is supported by evidence that the use of imagery, hypnosis, biofeedback and other ‘mental interventions’ can be therapeutic in a variety of medical conditions. However, there is no accepted theory of mind/body interaction and this has had a detrimental effect on the acceptance of mental causation in science, philosophy and in many areas of clinical practice. Biomedical accounts typically translate the effects of mind into the effects of brain functioning, for example, explaining mind/body interactions in terms of the interconnections and reciprocal control of cortical, neuroendocrine, autonomic and immune systems. While such accounts are instructive, they are implicitly reductionist, and beg the question of how conscious experiences could have bodily effects. On the other hand, non-reductionist accounts have to cope with three problems: 1) The physical world appears causally closed, which would seem to leave no room for conscious intervention. 2) One is not conscious of one’s own brain/body processing, so how could there be conscious control of such processing? 3) Conscious experiences appear to come too late to causally affect the processes to which they most obviously relate. This paper suggests a way of understanding mental causation that resolves these problems. It also suggests that “conscious mental control” needs to be partly understood in terms of the voluntary operations of the preconscious mind, and that this allows an account of biological determinism that is compatible with experienced free will

This review summarises why it is difficult for Darwinian evolutionary theory to explain the existence and function of consciousness. It then evaluates whether Humphrey's book Soul Dust overcomes these problems. According to Humphrey, consciousness is an illusion constructed by the brain to enhance reproductive fitness by motivating creatures that have it to stay alive. Although the review entirely accepts that consciousness gives a first-person meaning to existence, it concludes that Humphrey does not give a convincing account of how this can arise from random variations in the genome. Nor does he demonstrate how first-person experiences might enter into or be reducable to third-person functioning. The review concludes that Humphrey's case is unconvincing, and goes on to suggest that an entirely different, non-reductive approach may be required to understand consciousness.

Classical ways of viewing the relation of consciousness to the brain and physical world make it difficult to see how consciousness can be a subject of scientific study. In contrast to physical events, it seems to be private, subjective, and viewable only from a subject's first-person perspective. But much of psychology does investigate human experience, which suggests that classical ways of viewing these relations must be wrong. An alternative, Reflexive model is outlined along with it's consequences for methodology. Within this model the external phenomenal world is viewed as part-of consciousness, rather than apart-from it. Observed events are only "public" in the sense of "private experience shared." Scientific observations are only "objective" in the sense of "intersubjective." Observed phenomena are only "repeatable" in the sense that they are sufficiently similar to be taken for "tokens" of the same event "type." This closes the gap between physical and psychological phenomena. Indeed, events out-there in the world can often be regarded as either physical or psychological depending on the network of relationships under consideration

This is an open peer commentary on O’Brien & Opie (1999) “A connectionist theory of phenomenal experience”, published as a target article in the Behavioral and Brain Sciences. O’Brien & Opie defend a “vehicle” rather than a “process” theory of consciousness largely on the grounds that only conscious information is “explicit”. I argue that preconscious and unconscious representations can be functionally explicit (semantically well-formed and causally active). I also suggest that their analysis of how neural activation space mirrors the information structure of phenomenal experience fits more naturally into a dual-aspect theory of information than into their reductive physicalism.

The study of consciousness in modern science is hampered by deeply ingrained, dualist presuppositions about the nature of consciousness. In particular, conscious experiences are thought to be private and subjective, contrasting with physical phenomena which are public and objective. In the present article, I argue that all observed phenomena are, in a sense, private to a given observer, although there are some events to which there is public access. Phenomena can be objective in the sense of intersubjective, investigators can be objective in the sense of truthful or dispassionate, and procedures can be objective in being well-specified, but observed phenomena cannot be objective in the sense of being observer-free. Phenomena are only repeatable in the sense that they are judged by a community of observers to be tokens of the same type. Stripped of its dualist trappings the empirical method becomes if you carry out these procedures you will observe or experience these results -- which applies as much to a science of consciousness as it does to physics.

This is an open-peer commentary on Newell, B.R. & Shanks, D.R. (2014) Unconscious influences on decision making, BBS, 37:1, pp. 1-61. Newell and Shanks’ critical review considers only a very limited sense in which mental processes can be thought of as either conscious or unconscious and consequently gives a misleading analysis of the role of consciousness in human information processing. This commentary provides an expanded analysis of conscious processing that also reveals the various ways in which mental processes are unconscious. This undermines Newell & Shanks' contention that, “evidence for the existence of robust unconscious influences on decision making and related behaviors is weak, and many of the key research findings either demonstrate directly that behavior is under conscious control or can be plausibly explained without recourse to unconscious influences”(p 19). On the contrary, evidence for the influence of unconscious mental processes on human behaviour is ubiquitous.

ABSTRACT. The following is an email interchange that took place between Dan Dennett and myself in the period 14th to 28th June, 2001. The discussion tries to clarify some essential features of the "heterophenomenology" developed in his book Consciousness Explained (1996), and how this differs from a form of "critical phenomenology" implicit in my own book Understanding Consciousness (2000), and developed in my edited Investigating Phenomenal Consciousness: new methodologies and maps (2000). The departure point for the discussion is a paper posted on Dan's website that summarises a related debate between Dan, David Chalmers and Alvin Goldman (Dennett, 2001). To make the discussion easier to follow, the multiple embeddings have been removed (restoring the sequence in which the comments were written). I have also corrected a few typos and grammatical errors. However, the text of the emails remains exactly the same. In Round 1, I suggest that scientific investigations of consciousness are better described as a form of "critical phenomenology" that accepts conscious experiences to be real rather than as a "heterophenomenology" which remains neutral about or denies their existence. Dan replies that I have misunderstood his position - he doesn't deny that conscious experiences exist. Conscious experiences just don't have the first-person phenomenal properties that they are commonly thought to have and, in his view, science remains neutral about the nature of such properties. In Round 2, I agree with Dan that science initially remains neutral about how to understand the nature of conscious experiences. Nevertheless, the phenomenology of consciousness provides the data that scientists are trying to understand. A better understanding of data does not, in general, make the data disappear. I also ask, "if you remove the phenomena from phenomenal consciousness, in what sense is whatever remains "consciousness"? And, if one removes all the phenomenal content from what one takes consciousness to be, doesn't this amount to a denial of the existence of "consciousness" in any ordinary sense of this term? Dan's reply likens beliefs in phenomenal properties to the belief in evil spirits causing disease. He has no doubts that diseases such as whooping cough and tuberculosis are real, but this doesn't require him to believe in evil spirits. And, what's left, once one removes phenomenal properties, is what a zombie and a so-called conscious person have in common: a given set of functional properties that enable them to carry out the tasks we normally think of as conscious. In Round 3, I summarise our similarities and differences. We agree that first-person reports are not incorrigible and that third-person information may throw light on how to interpret them. We also agree that first-person reports are reports of "something", although we disagree about the nature of that something. I suggest that Dan is sceptical about first-person reports rather than heterophenomenologically "neutral" (e.g. when he likens belief in phenomenal properties to belief in evil spirits). While we agree that science is likely to deepen our understanding of consciousness, I repeat that, unlike the replacement of old theories by better theories, a deeper understanding of phenomena does not in general replace the phenomena themselves. Rather than third-person data replacing first-person reports, the former are required to make sense of the latter, making their relationship complementary and mutually irreducible. In fact, there are many cases where science takes the reality of first-person phenomenology seriously, for example in the extensive literature on pain and its alleviation. If this can't be squeezed into an exclusively third-person view of science, then we will just have to adjust our view of science - something that a "critical phenomenology" achieves at little cost. At the time of this editing, Dan has not replied. . Reference. Dennett, D. (2001) The fantasy of first-person science. http://ase.tufts.edu/cogstud/pubpage.htm.
