Contemporary theories of consciousness are based on widely different concepts of its nature, most or all of which probably embody aspects of the truth about it. Starting with a concept of consciousness indicated by the phrase “the feeling of what happens” (the title of a book by Antonio Damásio), we attempt to build a framework capable of supporting and resolving divergent views. We picture consciousness in terms of Reality experiencing itself from the perspective of cognitive agents. Each conscious experience is (...) regarded as composed of momentary feeling events that are combined by recognition and evaluation into extended conscious episodes that bind cognitive contents with a wide range of apparent durations (0.1 secs to 2 or more secs, for us humans, depending on circumstances and context). Three necessary conditions for the existence of consciousness are identified: a) a ground of Reality, envisaged as an universal field of potentiality encompassing all possible manifestations, whether material or 'mental'; b) a transitional zone, leading to; c) a manifest world with its fundamental divisions into material, 'informational' and quale-endowed aspects. We explore ideas about the nature of these necessary conditions, how they may relate to one another and whether our suggestions have empirical implications. (shrink)

Analogy with the monisms of fundamental physics suggests that a concept of symmetry breaking is likely to help towards developing an understanding of mind/matter monism. I explore some possible consequences of this concept, arguing that a broken symmetry, involving energy and 'what-it-is-like-to-be-ness'along with time, may occur and may manifest in the course of energy measurements. The resultant proto-panpsychist picture has the advantage of indicating how our complex, human consciousness could emerge from proto-conscious elements. It's an account that has empirical, refutable (...) implications which are briefly discussed. (shrink)

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. (shrink)

This paper starts with an overview of C.G. Jung’s notion of archetypes. His ideas imply that Jungian archetypes can be viewed as the most general examples of the shared awarenesses that occur in groups of people of all sizes, ranging from families to humanity as a whole. The term ‘archetype’ is used in connection with such shared awarenesses in the subsequent discussion. The distinction that Jung made between archetypal representations and archetypes themselves is retained and emphasized. It is then pointed (...) out that archetypal representations are sets of Dawkins’ memes appearing in awareness. Pursuing the line of thought suggested by this, it is further proposed that the meme set can be regarded as analogous to the genotype in biology, while the representation itself resembles the phenotype in heuristically useful respects. Archetypes, as opposed to their representations, are the factors which predispose particular sets of memes to spread within a group of people and enter their awarenesses. It follows from the biological analogy that archetypes can be thought of as regularities that occur in an ‘ecology’ of representations. Because memes are subject to pseudo-Darwinian influences, parallels between the behaviour of representations and the phenomena of parasitology and epidemiology will sometimes be observed. The view of archetypes arrived at opens up a possibility that they might be responsible for some mass behaviours; e.g. those involved in the production of social movements such as Nazism or certain medical conditions of obscure aetiology. Archetypal representations possess in some circumstances the power to fill the consciousnesses of individuals ‘infected’ by them for long periods of time. These points are illustrated in a brief account of fatigue syndromes. Finally, should consciousness have a quantum theoretical basis, details of the epidemiology of archetypal representations will differ from those to be expected if it has no such basis. The phenomenon of alien abduction, presumed to be of archetypal origin, is discussed as an example. (shrink)

Annotation Up-to-date and accessible examination of scientific thinking about the nature of consciousness. Chris Nunn sets out the most exciting theoretical and experimental advances in this fast developing and controversial area.

Experiments are described, using electroencephalography (EEG) and simple tests of performance, which support the hypothesis that collapse of a quantum field is of importance to the functioning of the brain. The theoretical basis of our experiments is derived from Penrose (1989) who suggested that conscious decision-making is a manifestation of the outcome of quantum computation in the brain involving collapse of some relevant wave function. He also proposed that collapse of any wave function depends on a gravitational criterion. As different (...) brain areas are known to subserve different functions, we argue that `Penrose collapse' must occur in a particular brain area when performing a task that uses it. Further, taking an EEG from the area should amplify the gravitational prerequisite for collapse, so affecting task performance. There are no non-quantum theories which could lead one to expect that taking an EEG could directly affect task performance by subjects. The results of both pilot and main experiments indicated that task performance was indeed influenced by taking an EEG from relevant brain areas. Control experiments suggested that the influence was quantum mechanical in origin, and was not due to any experimental artefact. The results are statistically significant and merit attempts at replication in an independent laboratory, preferably with more sophisticated equipment than was available to us. (shrink)

This book is about how we make choices. It is a compelling analysis of the nature of free will, drawing together evidence from chemistry, literature, politics, history and beyond. Psychiatrist Chris Nunn elegantly explores the revolutions in medicine, genetics, bioethics and neuroscience spurred by Julien de la Mettrie's 300-year-old tract Man the Machine . Nunn concludes that a mechanistic view of the human brain, though once fruitful, is now moribund. He proposes a powerful alternative: that stories, recorded in our memories (...) throughout life, are the mediators of free choice. Nunn demonstrates how this original approach could reconcile the latest brain-imaging results and our seemingly contradictory intuition about decision making and responsibility. (shrink)

First a confession: your reporter did not attend every session of this fascinating workshop. It was held in a vast centre, vaguely reminiscent of the Potsdam palace, set in an Alpine valley and a favourite venue for conferences. Inside, labyrinthine corridors-- both literal and metaphorical; outside, glorious mountains, deep forests, a sparkling lake, some of the prettiest villages in the world. You get the picture, and can appreciate the temptation! So this report is no doubt unbalanced to some extent, and (...) is very much a personal view of the proceedings. (shrink)

Following a theme which increasingly interests people concerned with problems of sentience, this paper describes how consciousness might encode information. The idea that awareness is inseparable from Bose-Einstein condensation in the brain is identified as the most promising of the ‘quantum consciousness’ notions. It can be inferred from this idea that brain Bose condensates will have a geometrical structure, analagous to that of tapestries, which can encode information and to which knot theory can be applied.These notions are able to explain (...) otherwise puzzling features of conscious information handling and a neuroanatomically testable prediction is derived from them. Finally it's pointed out that they imply that any ‘strong’ panpsychist position is unnecessary. (shrink)

Here is an account of mentality and human experience, written for a multi-disciplinary readership. The focus is on how mind, consciousness and selves inter-relate, extending into exploration of ideas about the nature of awareness and a search for relevant evidence.‘Consciousness studies’ has reached something of a crossroads nowadays. Computational approaches to mind and ‘quantum consciousness’ theories, have not lived up to early hopes. Neuroscience has made huge strides in the last few years, but is still nowhere near able to account (...) for the existence of consciousness itself - as opposed to being able to explain how some of its content gets there. Philosophically, there is lack of consensus over both the nature of consciousness and what questions we should be asking about it.Chris Nunn's book surveys the current situation and argues that, as far as ‘mind’ is concerned, we need to take the overall dynamics into consideration, which include genetic, environmental and social factors along with neurology. He emphasizes the close links that exist between memory, experience and personhood. What emerges most strongly from this account is that answers to questions about the nature of consciousness are likely to depend on achieving a better understanding of the physics of time.Chris Nunn is a psychiatrist who researched mind/body relationships and bipolar disorder. He has been involved in the ‘consciousness studies’ movement since 1992. (shrink)
