Consciousness and the Interpretation of Quantum Mechanics

I argue that the wave function ontology for quantum mechanics is an undesirable ontology. This ontology holds that the fundamental space in which entities evolve is not three-dimensional, but instead 3N-dimensional, where N is the number of particles standardly thought to exist in three-dimensional space. I show that the state of three-dimensional objects does not supervene on the state of objects in 3N-dimensional space. I also show that the only way to guarantee the existence of the appropriate mental states in (...) the wave function ontology has undesirable metaphysical baggage: either mind/body dualism is true, or circumstances which we take to be logically possible turn out to be logically impossible.

The idea of self-measurement by a quantum-mechanical automaton is presented, and the conclusions that are typically reached about what we can come to know from doing self-measurements are shown to be mistaken. Specifically, it is shown that, while we are capable of _predicting_ and _measuring_ the values of two incompatible observables, we are incapable of _knowing_ both these values simultaneously. This is an example of the interesting limitations quantum mechanics places on knowledge.

Bu çalışma kitap olmayan bir kitaptır. Okur klasik kitaplarda alıştığı tamamlanmış metinler, çözümlenmiş bilimsel ve felsefi problemler beklemesin bu çalışmada. Sunduğum şey üzerinde çalıştığım konular ve o konularla ilgili geliştirdiğim düşünceler, aforizmalar yer yer dağınık önermelerdir.

Quantum çağında her gün yeni bir keşif yaptığımız nesneler ile ilgili büyük anlatılar ve tamamlanmış, sistematik görüşler geliştirilemez. Geleneksel tüm kitaplar ilgilendikleri nesneyi tüm bağıntılarıyla çözdükleri iddiasındadır. Örneğin tüm çağdaş fizik (...) kitapları yaklaşık yüz yıldır atomun ağırlığını çözdüklerini düşünerek yayınlanıyordu. Ancak 2017 Ocağında quarkların dışarıdan enerji alışverişi yaptıkları ve oluşturdukları atom ağırlığının sürekli değişti keşfedildi. Bu tüm yazılmış fizik kitaplarının çöpe atılması anlamına gelir. Bu nedenlerden ötürü tamamlanmış çalışmalar değil, sürekli gelişen Wikipedia tarzında, yazılan metinlerin sürekli güncellendiği çalışmalar, bilimsel anlatıma daha uygundur. Okur, bu metnin sürekli işlenen biçimini bloğumda takip edebilecek. -/- İkincisi kişisel olarak çalışmalarımdan asla tatmin olamadım ve vardığım teorik sonuçları dışarı açarak çalışmalarıma dışsal bir motivasyon ve eleştirel bir geri dönüşüm almak istedim. O nedenle okur bu çalışmamı kendisiyle tartışmaya açtığım el yazmalarım olarak değerlendirsin. -/- Tüm bunlarla birlikte okuru son derece geniş bir entelektüel alanda yaratıcı bir çalışma ve tamamiyle sadece yazara ait yeni önermeler bekliyor. -/- Bu çalışma esas olarak aydınlanmadan başlayan ve günümüze kadar gelen, quantum fizikçilerinin de yaslandıkları, tüm sosyal kuramların sonunu ilan etmektedir. -/- Salt bu iddia bile çalışmamı dikkate değer kılar.

Starting with 1985, we discovered the possible existence of electrons with net helicity in biomolecules as amino acids and their possibility to discern between the two quantum spin states. It is well known that the question of a possible fundamental role of quantum mechanics in biological matter constitutes still a long debate. In the last ten years we have given a rather complete quantum mechanical elaboration entirely based on Clifford algebra whose basic entities are isomorphic to the well known spin (...) Pauli matrices. A number of our recent results indicate the possible logical origin of quantum mechanics and the direct admission of quantum mechanics in the field of cognitive sciences. In February 2011 the authors Gölder et al., published their important discovery on Science about Spin Selectivity in Electron Transmission Through Self-Assembled Monolayers of Double-Stranded DNA confirming in such manner that the principles of quantum mechanics apply to biological systems.

In neurophysiology it is widely assumed that our mind operates in millisecond timescale. This view might be wrong, because if consciousness is quantum coherent phenomenon at the level of protein assemblies, then its dynamic timescale can be picosecond one.

This book addresses the fascinating cross-disciplinary field of quantum information theory applied to the study of brain function. It offers a self-study guide to probe the problems of consciousness, including a concise but rigorous introduction to classical and quantum information theory, theoretical neuroscience, and philosophy of the mind. It aims to address long-standing problems related to consciousness within the framework of modern theoretical physics in a comprehensible manner that elucidates the nature of the mind-body relationship. The reader also gains an (...) overview of methods for constructing and testing quantum informational theories of consciousness. (shrink)

Der folgende Vortrag hat zwei Teile. Teil 1 hat mit dem Internet zu tun und mit neuen Entwicklungen im Bereich des so genannten „ontological engineering“. Teil 2 hat zu tun mit der kantischen Philosophie und mit neuen Versuchen, diese Philosophie mit Hilfe der Quantenphysik zu unterstützen. Diese zwei Teile sind nicht vollkommen unabhängig voneinander, aber die Verbindung zwischen den zwei Teilen wird erst im Laufe des Vortrags klar werden.

This philosophical anthropology tries to explore the basic categories of man’s being in the worlds using a special quantum meta-ontology that is introduced in the book. Quantum understanding of space and time, consciousness, or empirical/nonempirical reality elicits new questions relating to philosophical concerns such as subjectivity, free will, mind, perception, experience, dialectic, or agency. The authors have developed an inspiring theoretical framework transcending the boundaries of particular disciplines, e.g. quantum philosophy, metaphysics of consciousness, philosophy of mind, phenomenology of space and (...) time, and ontological relativity.

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.

In 2005, an essay was published in Nature asserting that the universe is mental and that we must abandon our tendency to conceptualize observations as things. Since then, experiments have confirmed that — as predicted by quantum mechanics — reality is contextual, which contradicts at least intuitive formulations of realism and corroborates the hypothesis of a mental universe. Yet, to give this hypothesis a coherent rendering, one must explain how a mental universe can — at least in principle — accommodate (...) (a) our experience of ourselves as distinct individual minds sharing a world beyond the control of our volition; and (b) the empirical fact that this world is contextual despite being seemingly shared. By combining a modern formulation of the ontology of idealism with the relational interpretation of quantum mechanics, the present paper attempts to provide a viable explanatory framework for both points. In the process of doing so, the paper also addresses key philosophical qualms of the relational interpretation. (shrink)

A number of researchers today make an appeal to quantum physics when trying to develop a satisfactory account of the mind, an appeal still felt to be controversial by many. Often these "quantum approaches" try to explain some well-known features of conscious experience (or mental processes more generally), thus using quantum physics to enrich the explanatory framework or explanans used in consciousness studies and cognitive science. This paper considers the less studied question of whether quantum physical intuitions could help us (...) to draw attention to new or neglected aspects of the mind in introspection, and in this way change our view about what needs explanation in the rst place. Although prima facie implausible, it is suggested that this could happen, for example, if there were analogies between quantum processes and mental processes (e.g., the process of thinking). The naive idea is that such analogies would help us to see mental processes and conscious experience in a new way. It has indeed been proposed long ago that such analogies exist, and this paper rst focuses at some length on David Bohm's formulation of them from 1951. It then briefly considers these analogies in relation to Smolensky's more recent analogies between cognitive science and physics, and Pylkko's aconceptual view of the mind. Finally, Bohm's early analogies will be briefly considered in relation to the analogies between quantum processes and the mind he proposed in his later work. (shrink)

In this paper we examine some proposals to disprove the hypothesis that the interaction between mind and matter causes the collapse of the wave function, showing that such proposals are fundamentally flawed. We then describe a general experimental setup retaining the key features of the ones examined, and show that even a more general case is inadequate to disprove the mind-matter collapse hypothesis. Finally, we use our setup provided to argue that, under some reasonable assumptions about consciousness, such hypothesis is (...) unfalsifiable. (shrink)

The limitations and unsuitability of the twentieth century intellectual marvel, the quantum mechanics for the task of unraveling working of human consciousness is critically analyzed. The inbuilt traits of the probabilistic, approximate and imprecise nature of quantum mechanical approach are brought out. -/- The limitations and the unsuitability of using such knowledge for the understanding of precise, correct, finite and definite happenings of activities relating to human consciousness and mind, which are not quantum in nature, are pointed out. -/- Analytical (...) methods interpreting philosophical and Indian spiritual analyses suiting the unraveling of working of human consciousness and mind over the deductive approach of quantum physics and advanced mathematics are highlighted. A model of human consciousness and mental functions is presented taking ideas from the Upanishads and related texts. -/- Comparisons with theological interpretations of Upanishadic insight are dealt with to have an idea of working of human consciousness and mind in relation to spirituality.

This book has been written for eighteen year olds (or anyone who will listen) as an honest attempt to face their justified questionings and to offer them a metaphysical framework with which to confront the twenty-first century. It is vitally important that certain modes of thought are uprooted and new modes put in their place if mankind and planet Earth are not soon to suffer an historic global catastrophe. Apart from the continuing world-wide proliferation of conventional, chemical, biological and nuclear (...) weaponry, the temperature of the planet has risen more rapidly in the last twenty-five years than it has since the year 900AD, which confirms global warming by some cause or other. These and the many intensifying human conflicts and natural disasters demand that some fundamental changes to our thinking are made as soon as possible. These 120 pages begin with an original examination of the quantum-theoretical understanding of reason (logic) and reality (existence) and find both to be at odds with common sense. A theory of everything is a reduction to a single grand idea! A quantum theory of everything is a mathematical theory of a consciousness realizing this grand idea! That is what this book tries to comprehend by means of five indisputable propositions. (shrink)

What is a physical object according to the theory of quantum mechanics? The first answer to be considered is that given by Bohr in terms of the concept of complementarity. This interpretation is illustrated by way of an example, the two slit experiment, which highlights some of the associated problems of ontology. One such problem is the so-called problem of measurement or observation. Various interpretations of measurement in Quantum Theory, including those of Heisenberg, von Neumann, Everett and Bohr, are compared (...) and contrasted. A second problem concerns whether or not QT can be considered complete and therefore satisfactory as a basis for physics. Various attempts to complete QT by means of the addition of ‘hidden variables’ to the quantum mechanical state function are considered and their aims and achievements assessed. Finally, we investigate some of the characteristic ontological problems for the orthodox interpretation of Relativistic Quantum Theory. -/- . (shrink)

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

To make educated guesses about what happens to consciousness upon bodily death, one has to have some understanding of the relationship between body and consciousness during life. This relationship, of course, reflects an ontology. In this brief essay, the tenability of both the physicalist and dualist ontologies will be assessed in view of recent experimental results in physics. The alternative ontology of idealism will then be discussed, which not only can be reconciled with the available empirical evidence, but also overcomes (...) the lack of parsimony and limited explanatory power of physicalism and dualism. Idealism elegantly explains the basic facts of reality, such as (a) the fact that brain activity correlates with experience, (b) the fact that we all seem to share the same world, and (c) the fact that we can’t change the laws of nature at will. If idealism is correct, the implication is that, instead of disappearing, conscious inner life expands upon bodily death, a prediction that finds circumstantial but significant confirmation in reports of near-death experiences and psychedelic trances, both of which can be construed as glimpses into the early stages of the death process.

The Many Worlds Interpretation (MWI) famously avoids the issue of wave function collapse. Different MWI trees representing the same quantum events can have different topologies, depending upon the observer. However, they are all isomorphic to the group of block universes containing all of the outcomes of all of the events, and so, in that sense, the group of block universes is a more fundamental representation. Different branches of the MWI tree, representing different universes in MWI, ultimately share the same quantum (...) state in a common ancestor branch. This branching topology is incompatible with that of the Minkowski block universe; the resolution is to replace the branches with discrete, parallel block universes, each of which extends from the trunk to the outermost twigs. The number of universes in a branch is proportional to its thickness which, in turn, depends upon the absolute square of the probability amplitude for the state in that branch. Every quantum event may be represented by a kernel of universes, which is the smallest group of universes that will reproduce the quantum probabilities of the outcomes of that event. By considering the ratios of the probabilities of the outcomes of any event, it can be shown that the number of universes in every kernel must finite, as must be the total number of universes in the multiverse. Further, every universe in the multiverse must be finite both in space and time. Another consequence is that quantum probabilities must be rational, which suggests that quantum mechanics is only an approximation to a discrete theory. A corollary is that not every conceivable universe exists in the multiverse, no doubt to the disappointment of those who enjoy alternate-history novels. (shrink)

Anthony Aguirre and Max Tegmark have famously speculated that the Level I Multiverse is the same as the Level III Multiverse. By this, they mean that the parallel universes of the Level III Multiverse can be regarded as similar or identical copies of our own Hubble volume distributed throughout the whole of our (possibly infinite) bubble universe. However, we show that our bubble universe is in a single quantum eigenstate that extends to regions of space that are receding from each (...) other at superluminal velocities because of general relativistic expansion. Such a bubble universe cannot accommodate Hubble volumes in the different orthogonal eigenstates required by the Level III Multiverse. Instead, quantum uncertainty arises from large numbers of alternative bubble universes in Hilbert space, isolated from each other. The conclusion of the paper is that the Level I Multiverse is not the same as the Level III Multiverse. (shrink)

Bas van Fraassen endorses both common-sense realism — the view, roughly, that the ordinary macroscopic objects that we take to exist actually do exist — and constructive empiricism — the view, roughly, that the aim of science is truth about the observable world. But what happens if common-sense realism and science come into conflict? I argue that it is reasonable to think that they could come into conflict, by giving some motivation for a mental monist solution to the measurement problem (...) of quantum mechanics. I then consider whether, in a situation where science favors the mental monist interpretation, van Fraassen would want to give up common-sense realism or would want to give up science. (shrink)

The Copenhagen interpretation of quantum entanglement experiments is at best incomplete, since the intermediate state induced by collapse of the wave function apparently depends upon the inertial rest frame in which the experiment is observed. While Everett’s Many Worlds Interpretation avoids the issue of wave function collapse, it, too, is a casualty of the special theory of relativity. This requires all events in the universe, past, present and future, to be unique, as in the block-universe picture, which rules out Everett-style (...) branching. The benefits of MWI may be retained, however, by postulating a multiverse of discrete, parallel, block universes which are identical to each other up to certain points in the MWI “trunk” before they diverge according to the MWI branching. The quantum probability of an event then emerges from the number of parallel universes in which the event happens divided by the total number of universes. This means that the total number of such universes is finite. Such a picture is more easily envisaged by thinking of it as a purely mathematical structure, as in Tegmark’s Mathematical Universe Hypothesis. However, while Tegmark wished to avoid contamination from Gödelian self-referential knots, not only does such contamination appear to be inevitable, it brings an unexpected benefit. The mathematical hierarchy required by Gödel’s enigmatic footnote 48a leads to an explanation for a unitary evolution of deterministic quantum rules across the multiverse while accounting for quantum uncertainty within an individual universe. Other aspects of this structure, called here the Plexus, are discussed, including awareness of existence and other questions raised by the hypothesis. (shrink)

If conscious observers are to be included in the quantum mechanical universe, we need to find the rules that engage observers with quantum mechanical systems. The author has proposed five rules that are discovered by insisting on empirical completeness; that is, by requiring the rules to draw empirical information from Schrödinger's solutions that is more complete than is currently possible with the (Born) probability interpretation. I discard Born's interpretation, introducing probability solely through probability “current.” These rules tell us something about (...) brains. They require the existence of observer brain states that are neither conscious nor unconscious. I call them “ready” brain states because they are on stand-by, ready to become conscious the moment they are stochastically chosen. Two of the rules are selection rules involving ready brain states. The place of these rules in a wider theoretical context is discussed. (shrink)

In a previous paper, the author proposed a quantum mechanical interaction that would insure that the evolution of subjective states would parallel the evolution of biological states, as required by von Neumann's theory of measurement. The particular model for this interaction suggested an experiment that the author has now performed with negative results. A modified model is outlined in this paper that preserves the desirable features of the original model, and is consistent with the experimental results. This model will be (...) more difficult to verify. However, some strategies are suggested. (shrink)

Consciousness defines our existence and reality. But how does the brain generate thoughts and feelings? Most explanations portray the brain as a computer, with nerve cells ("neurons") and their synaptic connections acting as simple switches, or "bits" which interact in complex ways. In this view consciousness is said to "emerge" as a novel property of complex interactions among neurons, as hurricanes and candle flames emerge from complex interactions among gas and dust molecules. However this approach fails to explain why we (...) have feelings and awareness, an "inner life". So we don't know how the brain produces consciousness. (shrink)

A profound change in our scientific understanding of the role of human beings in the unfolding of our streams of conscious experiences was wrought by the 20th-century switch from classical mechanics to quantum mechanics. The streams of consciousness thoughts of human beings were converted from causally inert passive witnesses of the unfolding of a mechanically controlled and causally self-sufficient physical universe into logically needed dynamical inputs into the physical aspects of nature. These physical aspects, as they are now understood, contain (...) causal gaps that are neatly filled by inputs from the realm of our conscious thoughts in a way that allows our conscious intentions to tend to produce their intended consequences.

Does introspection grant us privileged insight into the intrinsic nature of the stuff of the world? Michael Lockwood 's startling answer is yes. Quantum mechanics may indeed supply a complete formal description of the universe. Yet what "breathes fire into" the quantum-theoretic equations, it transpires, isn't physical in the traditional sense at all.

William Robinson has asked some detailed and pertinent questions that probe essential features of the quantum mind matter synthesis I proposed. They demand detailed answers, which I shall give here. These answers rest on technical properties of quantum theory. But I believed I can describe the points in a way will be clear to non physicist.

Today we’re talking with Stuart Hameroff, Professor Emeritus at the Departments of Anesthesiology and Psychology, and Director of the Center for Consciousness Studies, at the University of Arizona. Dr Hameroff is best-known for his research on 'quantum consciousness', an alternative model to the accepted view of how consciousness arises. With Sir Roger Penrose, Dr Hameroff has proposed that consciousness arises at the quantum level within structures inside neurons, known as microtubules.

Anesthetic gas molecules are recognized to act by van der Waals (London dispersion) forces in hydrophobic pockets of select brain proteins to ablate consciousness. Enigmatic features of consciousness have defied conventional neurophysiological exp lanations and prompted suggestions for supplemental occurrence of macroscopic quantum coherent states and quantum computation in the brain. Are these feasible? During conscious (non-anesthetic) conditions, endogenous Van der Waals London dispersion forces occur among non-polar amino acid groups in hydrophobic pockets of neural proteins and help regulate their (...) conformation/function. London forces are weak instantaneous couplings between pairs of electron induced dipoles (e.g. between adjacent non-polar amino acid groups), and are quantum mechanical effects capable of supporting quantum superposition/computation and macroscopic quantum coherence. Quantum effects mediated by endogenous London forces in hydrophobic pockets of select neural proteins may be necessary for consciousness. The mechanism of anesthetics may be to inhibit (by exogenous London forces) the necessary quantum states. (shrink)

By explicitly discussing the connections between quantum mechanics and consciousness and bravely using the book containing these discussions as course material for students, the authors show the readers and teach the students that such connections are real and tangible not just pseudoscience or New Age mumbo-jumbo. In doing so, Rosenblum and Kuttner lead by example. Hopefully, other physicists and scientists in the academics would follow suit by breaking away from the invisible “prison” of conformity and orthodoxy, opening widely physicists’ closet (...) containing their skeleton and turning the same into golden opportunities for solving the mystery of consciousness. I highly recommend this book. (shrink)

This article takes as its point of departure the view that the discovery of the mathematical formalism of quantum mechanics (QM) was not merely a discovery of a new mathematical way of dealing with physical, and specifically quantum, processes in nature. It was also a discovery of a general mathematical formalism (in part discovered in mathematics itself earlier), which, supplemented by certain additional rules, consistently described the processing of incomplete information about certain events and contexts in which these events occur. (...) This article proposes a quantum-like (QL) model of the functioning of the brain based on the (Hilbert-space) formalism of quantum mechanics, but now used as part of a QL mathematical model of neural processes in the brain, rather than for describing quantum physical processes. This model is, thus, fundamentally different from the (reductionist) quantum model of the brain and consciousness, according to which cognition arises by virtue of physical quantum processes in the brain. In the present view, the brain is an advanced biological system that developed the ability to create a QL representation of contexts, which, thus, allows one to describe a significant part of its functioning by the QM mathematical formalism. The possibility of such a description has nothing to do with the constitution and workings of the brain as a quantum system (composed of photons, electrons, protons, and so forth). The QL model offered here is based instead on conventional neurophysiological model of the functioning of the brain, even though the brain, the article suggests, does use the QL rule (given by von Neumann trace formula, used in QM) for the calculation of approximate averages for mental functions. The QL model developed in this article has a temporal basis, based on a (hypothetical) argument that cognitive processes are based on at least two time scales: a (very fine) subcognitive one and a (much coarser) cognitive one.

Throughout human history, thoughts, values and behaviors have been colored by language and the prevailing view of the universe. With the advent of Quantum Mechanics, relativity, non-Euclidean geometries, non-Aristotelian logic and General Semantics, the scientific view of the world has changed dramatically from just a few decades ago. Nonetheless, human thinking is still deeply rooted in the cosmology of the middle ages. Quantum Psychology is the book to change your way of perceiving yourself--and the universe for the 21st Century. Some (...) say it's materialistic, others call it scientific and still others insist it's mystical. It is all of these--and none. (shrink)

In response to recent suggestions that the phenomena of consciousness may be related to those described by quantum theory, it is argued that distinctive features of brain activity are more typical of nonlinear classical dynamics than of quantum dynamics, which is a linear theory. Thus natural scientists should turn to hierarchies of nonlinear classical systems rather than quantum theory for explanations of the brain's mysterious behaviour.

Goswami proposes to replace the current scientific paradigm of physical realism with that of a quantum-based monistic idealism and, in the process, accomplish the following goals: establish a basis for explaining consciousness, reintegrate spirituality, mysticism, morality, a sense that the universe is meaningful, etc., with scientific discoveries and the scientific enterprise, and support the assumption that humans possess free will - i.e., that they are not controlled by the apparently inexorable causality of the physical laws that govern the functioning of (...) their brains. Here, we critically examine this approach, from an artificial intelligence and neural network perspective, and point out what appear to be some inherent weaknesses in Goswami's arguments. (shrink)

In this book, Hodgson presents a clear and compelling case against today's orthodox mechanistic view of the brain-mind, and in favor of the view that "the mind matters." In the course of the argument he ranges over such topics as consciousness, informal reasoning, computers, evolution, and quantum indeterminancy and non-locality. Although written from a philosophical viewpoint, the book has important implications for the sciences concerned with the brain-mind problem. At the same time, it is largely non-technical, and thus accessible to (...) the non-specialist reader. (shrink)

We argue that either the insect has a mind, therefore collapsing the wave function, or it does not, therefore reacting to superpositions in a different way. Thus, a device to condition insects could be used to test von Neumann's interpretation, if insects are not conscious. If, on the other hand, insects (...) possess a mind, such experiment would open up the possibility of using insect experiments to test Stapp's theory of mind-matter interaction. (shrink)

The central claim that understanding quantum mechanics requires a conscious observer, which is made by B. Rosenblum and F. Kuttner in their book “Quantum Enigma: Physics encounters consciousness”, is shown to be based on various misunderstandings and distortions of the foundations of quantum mechanics.

Consciousness remains one of the major unsolved problems in science. How do the feelings and sensations making up conscious experience arise from the concerted actions of nerve cells and their associated synaptic and molecular processes? Can such feelings be explained by modern science, or is there an entirely different kind of explanation needed? And how can this seemingly intractable problem be approached experimentally? How do the operations of the conscious mind emerge out of the specific interactions involving billions of neurons? (...) This book seeks answers to these questions on the underlying assumption that consciousness can be understood using the intellectual potential of modern physics and other sciences. There are a number of theories of consciousness, some based on classical physics while others require the use of quantum concepts. The latter ones have drawn criticism from the parts of the scientific establishment while simultaneously claiming that classical approaches are doomed to failure. The contributing authors present a spectrum of opinions from both sides of this on-going scientific debate, allowing readers to decide for themselves which of the approaches are most likely to succeed.

How is mind related to matter? This ancient question in philosophy is rapidly becoming a core problem in science, perhaps the most important of all because it probes the essential nature of man himself. The origin of the problem is a conflict between the mechanical conception of human beings that arises from the precepts of classical physical theory and the very different idea that arises from our intuition: the former reduces each of us to an automaton, while the latter allows (...) our thoughts to guide our actions. The dominant contemporary approaches to the problem attempt to resolve this conflict by clinging to the classical concepts, and trying to explain away our misleading intuition. But a detailed argument given here shows why, in a scientific approach to this problem, it is necessary to use the more basic principles of quantum physics, which bring the observer into the dynamics, rather than to accept classical precepts that are profoundly incorrect precisely at the crucial point of the role of human consciousness in the dynamics of human brains. Adherence to the quantum principles yields a dynamical theory of the mind/brain/body system that is in close accord with our intuitive idea of what we are. In particular, the need for a self-observing quantum system to pose certain questions creates a causal opening that allows mind/brain dynamics to have three distinguishable but interlocked causal processes, one micro-local, one stochastic, and the third experiential. Passing to the classical limit in which the critical difference between zero and the finite actual value of Planck's constant is ignored not only eliminates the chemical processes that are absolutely crucial to the functioning of actual brains, it simultaneously blinds the resulting theoretical construct to the physical fine structure wherein the effect of mind on matter lies: the use of this limit in this context is totally unjustified from a physics perspective.

I argue that a dual-aspect theory of consciousness, associated with a particular class of quantum states, can provide a consistent account of consciousness. I illustrate this with the use of coherent states as this class. The proposal meets Chalmers 'requirements of allowing a structural correspondence between consciousness and its physical correlate. It provides a means for consciousness to have an effect on the world (it is not an epiphenomenon, and can thus be selected by evolution) in a way that supplements (...) and completes conventional physics, rather than interfering with it. I draw on the work of Hameroff and Penrose to explain the consistency of this proposal with decoherence, while adding details to this work. The proposal is open to extensive further research at both theoretical and experimental levels. (shrink)
