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)

Before any attempt is made to solve the problem with which this paper deals, it is necessary to convince the reader that the problem exists. Much is written and said to-day about class distinctions, both by those who announce with satisfaction their growing disappearance, and by those who half guiltily admit their existence, but it never seems to occur to such writers that the nature of these distinctions is itself something of a mystery. We take it for granted as one (...) of the most obvious and commonplace facts of daily life. It seems hardly likely that the examination of a thing so ubiquitous and immemorial will yield anything new. My object will be to maintain that this attitude is mistaken, and that the idea of “class” is not really self-explanatory, but deserves a closer analysis than it usually gets. And if this proves to be the case, it must be admitted that the subject is of importance. Many political and social problems are deeply involved in the fact of class distinctions. Many who believe in a possible regeneration of human society would gladly surrender much to secure a world where poverty should be no more, yet hesitate before the prospect of a loss, through diffusion, of cultural values which they feel to be infinitely precious, and which give to the existing order a greater claim to permanence than it would otherwise possess. We most of us hardly know our own minds in this matter. We yield social distinctions their place, but we do so shamefacedly, as though confessing to a mere unjustified conservatism. (shrink)

Functionalism offers an account of the relations that hold between behavioural functions, information and neural processing, and conscious experience from which one can draw two inferences: for any discriminable difference between qualia there must be an equivalent discriminable difference in function; and for any discriminable functional difference within a behavioural domain associated with qualia, there must be a discriminable difference between qualia. The phenomenon of coloured hearing synaesthesia appears to contradict the second of these inferences. We report data showing that (...) this form of synaesthesia is genuine and probably results from an aberrant projection from cortical language areas to a region specialized for the perception of colour. Since functionalism purports to be a general account of consciousness, one such negative instance, if it can be further sustained empirically, is sufficient to invalidate it. (shrink)

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)

In a recent article (Inquiry, Vol. 19 [1976]), J. W. Meiland addresses the issue of psychologism in logic, which holds that logic is a branch of psychology and that logical laws (such as the Principle of Non?Contradiction) are contingent upon the nature of the mind. Meiland examines Husserl's critique of psychologism, argues that Husserl is not convincing, and offers two new objections to the psychologistic thesis. In this paper I attempt to rebut those objections. In question are the acceptable criteria (...) for determining the possibility or impossibility of systems of logic significantly different from our own. I argue that a criteriological application of our accepted laws of logic to this question commits a circular fallacy. I then argue that, even if we accept logical consistency as a criterion for possibility, a plausible argument for the possibility of valid alternative logics can be constructed by using the functionalist analogy between minds and automata. Finally, I attempt to rebut the claim that in logic the only changes possible are conceptual changes that would not permit a proposition to be both true and false. (shrink)

Global Media Ethics is the first comprehensive cross-cultural exploration of the conceptual and practical issues facing media ethics in a global world. A team of leading journalism experts investigate the impact of major global trends on responsible journalism. The first full-length, truly global textbook on media ethics; Explores how current global changes in media promote and inhibit responsible journalism; Includes relevant and timely ethical discussions based on major trends in journalism and global media; Questions existing frameworks in media ethics in (...) light of the impact of global media; Contributors are leading experts in global journalism and communication.

Some philosophers suspect that the functionalist account of mind supports a psychologistic account of logic. One who has argued for a connection of this kind is Remmel T. Nunn. If the connection holds, it might be a powerful support for the currently unfashionable position of psychologism; conversely, it might be a damaging objection to functionalism. In either case, to estabjish the connection would be an achievement of considerable philosophic interest.

This looks at three educational developments influenced by the idealism of T H Green and others. One was progressive education - under Holmes and Nunn, another the pursuit of understanding for its own sake, and the third education for a participatory democracy. John Dewey had a role in both the last two.

In The Face of Emotions, which was Carroll Izard’s first major attempt at elaborating his differential emotions theory, he stated that the book “presents a theoretical framework for the study of emotions and their role in personality and interpersonal processes.” Yet, over the years, his contribution to personality theory has generally been overshadowed by the attention focused on his views on facial expressions and the structure of emotions. This article will begin with a brief overview of the DET perspective on (...) personality development. Then, it will examine how the DET framework can be used to organize recent findings from three lines of research on adult personality. It will conclude with suggestions for future research as well as some personal recollections. (shrink)

Much of the progress in the fields constituting cognitive science has been based upon the use of explicit information processing models, almost exclusively patterned after conventional serial computers. An extension of these ideas to massively parallel, connectionist models appears to offer a number of advantages. After a preliminary discussion, this paper introduces a general connectionist model and considers how it might be used in cognitive science. Among the issues addressed are: stability and noise‐sensitivity, distributed decision‐making, time and sequence problems, and (...) the representation of complex concepts. (shrink)

The purpose of this article is to highlight ways in which institutional policymakers tend to insufficiently conceptualise their role as ethics practitioners. We use the case of blood product recall notification as a means of raising questions about the way in which, as we have observed it, discourse for those who make institutional ethics policies is constrained by routine balancing of simplified principles to the exclusion of reflexive practices—those that turn ethics reasoning back on itself. The latter allows ethics practitioners (...) with comparatively little formal training to take ownership of traditional parameters, which define their discussions and ultimately ought to make them more insightful when doing ethics. Thus, in the midst of calls for more training to increase the competency of ethics committees, we suggest that an additional problem of how these lay ethicists conceive of their roles also needs to be addressed.

Establishment holds that thc psychological mechanism of inference is the ment psychological thcorizing. Moreover, given this conciliatory reading, transformation of mental representations, it follows that perception is in.

A simple transposition in the text would, I venture to suggest, remove one or two of the many difficulties of this obscure chapter.

Some philosophers hold that philosophy is what you do to a problem until it’s clear enough to solve it by doing science. Others hold that if a philosophical problem succumbs to empirical methods, that shows it wasn’t really philosophical to begin with. Either way, the facts seem clear enough: questions first mooted by philosophers are sometimes coopted by people who do experiments. This seems to be happening now to the question: “what are propositional attitudes?” and cognitive psychology is the science (...) of note. (shrink)

Im Jahrgang LXV der Recherches de Théologie et Philosophie médiévales wurde die Reihe «Entretiens» inauguriert, in der angesehene Forscher auf dem Gebiet der mittelalterlichen Theologie und Philosophie zu ihrem persönlichen Werdegang als Forscher, zu ihren Forschungsschwerpunkten und zur Zukunft der Mittelalterforschung Auskunft geben. Das zweite Interview führten Jan A. Aertsen und Andreas Speer mit Wolfgang Kluxen, emeritierter Ordinarius für Philosophie in Bonn, von 1972 bis 1982 Präsident, später président d’honneur der Société Internationale pour l’Étude de la Philosophie Médiévale.

Was Metaphysik ist, läßt sich nicht apriorisch bestimmen, sondern zeigt sich erst in den denkerischen Entwürfen eines Ersten und Grundlegenden. Metaphysik ist, wie Philosophie überhaupt, von ihrer Geschichte nicht trennbar. Die philosophische Bedeutung der Periode des Mittelalters für den Gang der abendländischen Metaphysik ist in den letzten Jahrzehnten durch zwei klassische Studien herausgestellt worden.

It's an achievement of the last couple of decades that people who work in linguistic semantics and people who work in the philosophy of language have arrived at a friendly, de facto agreement as to their respective job descriptions. The terms of this agreement are that the semanticists do the work and the philosophers do the worrying. The semanticists try to construct actual theories of meaning (or truth theories, or model theories, or whatever) for one or another kind of expression (...) in one or another natural language; for example, they try to figure out how the temperature could be rising compatibly with the substitutivity of identicals. The philosophers, by contrast, keep an eye on the large, foundational issues, such as: what's the relation between sense and denotation; what's the relation between thought and language; whether translation is determinate; and whether life is like a fountain. Every now and then the philosophers and the semanticists are supposed to get together and compare notes on their respective progress. Or lack thereof. (shrink)

Forty years’ experience as a bacterial geneticist has taught me that bacteria possess many cognitive, computational and evolutionary capabilities unimaginable in the first six decades of the twentieth century. Analysis of cellular processes such as metabolism, regulation of protein synthesis, and DNA repair established that bacteria continually monitor their external and internal environments and compute functional outputs based on information provided by their sensory apparatus. Studies of genetic recombination, lysogeny, antibiotic resistance and my own work on transposable elements revealed multiple (...) widespread bacterial systems for mobilizing and engineering DNA molecules. Examination of colony development and organization led me to appreciate how extensive multicellular collaboration is among the majority of bacterial species. Contemporary research in many laboratories on cell–cell signaling, symbiosis and pathogenesis show that bacteria utilise sophisticated mechanisms for intercellular communication and even have the ability to commandeer the basic cell biology of ‘higher’ plants and animals to meet their own needs. This remarkable series of observations requires us to revise basic ideas about biological information processing and recognise that even the smallest cells are sentient beings.
