The aim of this paper is to demonstrate a _prima facie_ tension between our commonsense conception of ourselves as thinkers and the connectionist programme for modelling cognitive processes. The language of thought hypothesis plays a pivotal role. The connectionist paradigm is opposed to the language of thought; and there is an argument for the language of thought that draws on features of the commonsense scheme of thoughts, concepts, and inference. Most of the paper (Sections 3-7) is taken up with the argument for the language of thought hypothesis. The argument for an opposition between connectionism and the language of thought comes towards the end (Section 8), along with some discussion of the potential eliminativist consequences (Sections 9 and.

Professor Strawson was interviewed on video on location at King's College, London during the Spring of 1992. Professor Strawson discusses his thoughts on a variety of topics on which he has written previously, providing some illuminating insights into how his thoughts has progressed. The text published here is en excerpt from this interview, translated with kind permission of Mr Rudolf V. Fara, the producer, in which prof. Strawson discusses his philosophical views with Martin Davies, Wilde Reader in Mental Philosophy at Oxford University, and Mark Sainsbury, Susan Stebbing Professor of Philosophy at King's College, University of London

Complementary and alternative therapiesThere has long been debate about the degree to which conventional health professionals should work closely with complementary and alternative medicine practitioners, if patients choose treatment from both. Some doctors are trained in conventional and alternative therapies but often, liaison depends on the type of therapy, whether it is regulated by law and whether it supplements conventional methods of diagnosis and treatment or claims to provide an alternative to them. Among the therapies often used by patients to supplement conventional medicine, but which do not claim to have a diagnostic purpose, are aromatherapy, massage, stress therapy, reflexology and hypnotherapy. Chinese medicine and homoeopathy are among those which are not statutorily regulated but claim to provide diagnosis and treatment. Practitioners of conventional medicine are often wary of unregulated treatments that supplant evidence-based therapy—even though not all conventional medicine has been proven by randomised controlled trials.The role of complementary and alternative therapies came under scrutiny in England in February 2010 when the Parliamentary Science and Technology Committee published a critical report on NHS funding for homoeopathy. 1 Focusing on whether government policy on homoeopathy was evidence-based, the Committee found a mismatch between the evidence and policy. Its main conclusion was that the evidence indicates that homoeopathy is not efficacious and does not produce results beyond the placebo effect. The Committee said that explanations for why homoeopathy was thought to work were implausible and that further homoeopathic clinical trials could not be justified. The amount that the NHS actually spends on homoeopathic therapies was left unclear and was subject to varying claims from the Society of Homoeopaths and the Health Minister.2 The Parliamentary report recommended that there should be a clear policy on prescribing placebos, including homoeopathic medicines, but the government has been …

Force-feeding of detainees at Guantánamo BayIn April, the US Department of Defense reportedly sent 40 additional military medical personnel, including doctors and nurses, to the Guantánamo Bay Naval Base to carry out the force-feeding of detainees on hunger strike.1 By the end of June, up to 104 of the remaining 166 individuals held in US military detention at Guantánamo were refusing food. The protest against conditions at the base, and the fate of those being held there—including those already cleared for transfer or release—began in February 2013. In June, it was reported that as many as 44 of the hunger strikers were being force-fed by military medical teams.2The response by the US authorities to the hunger strike prompted expressions of outrage from the international medical community.3,4 In April, the American Medical Association wrote to the US secretary of defense, insisting that ‘forced feeding of [competent] detainees violates core ethical values of the medical profession.’5 Adding the voice of the profession in the UK to these calls, at its annual conference in June, the British Medical Association condemned the participation of doctors and nurses in the force-feeding, calling on governments worldwide to ensure that all prisoners have access to confidential, independent medical treatment, and supporting any clinician who challenged cruel, inhuman or degrading treatment. Also in June, the BMA Chairman wrote to President Obama and US secretary of defense, Hagel, urging them to immediately suspend medical involvement in force-feeding at Guantánamo, and to institute an urgent inquiry into how the current situation was allowed to develop.Force-feeding mentally competent adults who are refusing food is a clear violation of medical ethics and is unjustifiable, as articulated by the World Medical Association's Declaration of Malta.6 Doctors with dual loyalties, including military doctors, are bound by the same …

Article copyright 2002. We provide a battery of examples of delusions against which theoretical accounts can be tested. Then we identify neuropsychological anomalies that could produce the unusual experiences that may lead, in turn, to the delusions in our battery. However, we argue against Maher's view that delusions are false beliefs that arise as normal responses to anomalous experiences. We propose, instead, that a second factor is required to account for the transition from unusual experience to delusional belief. The second factor in the etiology of delusions can be described superficially as a loss of the ability to reject a candidate for belief on the grounds of its implausibility and its inconsistency with everything else that the patient knows, but we point out some problems that confront any attempt to say more about the nature of this second factor.

A major recurrent feature of the intellectual landscape in cognitive science is the appearance of a collection of essays by Noam Chomsky. These collections serve both to inform the wider cognitive science community about the latest developments in the approach to the study of language that Chomsky has advocated for almost fifty years now,1 and to provide trenchant criticisms of what he takes to be mistaken philosophical objections to this approach. This new collection contains seven essays, the earliest of which were first published about ten years ago. So the linguistic work that is summarised is within the principles and parameters approach and some of the essays (particularly the first and last) provide an outline of the main ideas of the emerging minimalist programme.2 But this is not primarily a book about the details of recent linguistic theory. Rather, in these essays Chomsky offers a wealth of critical commentary on some of the most influential arguments in the philosophy of mind and language that have appeared over the past two decades or so. Indeed, Chomsky discusses a vast range of philosophical topics and reaches some radical conclusions – that many influential philosophical discussions on language and mind are utterly misconceived and that, for example, the traditional mind-body problem cannot even be coherently stated.

The paper makes three points about the role of double dissociation in cognitive neuropsychology. First, arguments from double dissociation to separate modules work by inference to the best, not the only possible, explanation. Second, in the development of computational cognitive neuropsychology, the contribution of connectionist cognitive science has been to broaden the range of potential explanations of double dissociation. As a result, the competition between explanations, and the characteristic features of the assessment of theories against the criteria of probability and explanatory value, are more visible. Third, cognitive neuropsychology is a division of cognitive psychology but the practice of cognitive neuropsychology proceeds on assumptions that go beyond the subject matter of cognitive psychology. Given such assumptions, neuroscientific findings about lesion location may enhance the value of double dissociation in shifting the balance of support between cognitive theories

Sitting in the philosopher’s armchair, I am not engaged in any detailed empirical investigation of the world. But, as I pursue philosophy’s distinctive armchair methodology, I sometimes come upon arguments that appear to disclose requirements for thought. According to some of these arguments, being a thinking person requires having the right kind of history, or having the right kind of cognitive architecture. According to other arguments, being able to think about particular topics requires being a member of a community of speakers, or being in contact with the right kinds of stuff. These arguments have the potential to raise an epistemological problem. For, suppose that armchair philosophical arguments such as these can yield knowledge about requirements for thought, and suppose too that I can know from the armchair that I am a thinking being who has thoughts about various particular topics. Then I seem to have a route to armchair knowledge about my history, my cognitive architecture, my community, and my material environment – knowledge about these things that does not depend on detailed empirical investigation of the world

As an undergraduate from 1964 to 1967, Gareth Evans, a British philosopher of language and mind, studied for the PPE degree (philosophy, politics and economics) at University College, Oxford, where his philosophy tutor was Peter Strawson. He was then a Senior Scholar at Christ Church, Oxford (1967–68) and a Kennedy Scholar visiting Harvard and Berkeley (1968–69). In 1968, less than a year after completing his degree, Evans was elected to a Fellowship at University College. He took up the position in 1969, succeeding Strawson who had become Waynflete Professor of Metaphysical Philosophy at Oxford. During the 1970s, Evans and his University College colleague John McDowell played leading roles in developing a distinctive conception of truth-theoretic semantics, drawing on the work of Strawson, Michael Dummett, and especially Donald Davidson. Their co-edited collection, Truth and Meaning: Essays in Semantics, appeared in 1976. While philosophy of language enjoyed a central position in Oxford philosophy of that period, Evans did not share the view (regarded by Dummett as constitutive of analytic philosophy) that philosophy of language is foundational and so takes priority over philosophy of mind in the order of philosophical explanation. He attached particular importance to the mentalistic notion of understanding, and his work on the theory of reference was set within a theory of thought and especially thought about particular objects. Evans’s published work ranged over philosophy of language, metaphysics, philosophy of mind, and philosophy of psychology. In 1979 he was elected to the Wilde Readership in Mental Philosophy at Oxford. He died in August 1980, at the age of thirtyfour. His book, The Varieties of Reference (1982), incomplete at the time of his death, was edited and brought to publication by McDowell. A collection of thirteen of his papers and two shorter notes appeared in 1985 and a further note was published in 2004..

Ever so often in the UK, there is a flurry of activity around the information requirements of donor-conceived individuals. In April 2013, it was the launch of a report from the Nuffield Council on Bioethics that brought the issue back to public consciousness.1Since 1991, information about treatment with donor gametes or embryos has been collected by the Human Fertilisation and Embryology Authority . Since then, over 35 000 donor-conceived individuals have been born through treatment in licensed clinics. Medical information and information about donors’ appearance are collected by clinics, and donors are encouraged to put together a ‘pen portrait’ giving information about themselves for any resulting children. One focus of the new report is on improving the quality and quantity of information available about donors.Traditionally, gamete and embryo donations were practised on an anonymous basis, so that those born as a result of such donation may receive only non-identifying information about the donor when they reach the age of 18 . This changed in 2005 when donor anonymity was removed so that anyone donating after that time could be identified to individuals born as a result of the treatment. Those who have donated in the past are also able to reregister as identifiable donors. Much concern was expressed at the time that this would exacerbate the shortage of donors although the Nuffield Council on Bioethics reports that, 8 years on, those clinics that actively recruit donors appear to be successful in finding sufficient donors. The report recommends that the option of anonymous donation should not be reintroduced.A big issue of debate in the UK has been, and continues to be, whether parents should tell their …

Mental simulation is the simulation, replication or re-enactment, usually in imagination, of the thinking, decision-making, emotional responses, or other aspects of the mental life of another person. According to simulation theory, mental simulation in imagination plays a key role in our everyday psychological understanding of other people. The same mental resources that are used in our own thinking, decision-making or emotional responses are redeployed in imagination to provide an understanding of the thoughts, decisions or emotions of another.

The nonvisual self-touch rubber hand paradigm elicits the compelling illusion that one is touching one’s own hand even though the two hands are not in contact. In four experiments, we investigated spatial limits of distance and alignment on the nonvisual self-touch illusion and the well-known visual rubber hand illusion. Common procedures and common assessment methods were used. Subjective experience of the illusion was assessed by agreement ratings for statements on a questionnaire and time of illusion onset. The nonvisual self-touch illusion was diminished though never abolished by distance and alignment manipulations, whereas the visual rubber hand illusion was more robust against these manipulations. We assessed proprioceptive drift, and implications of a double dissociation between subjective experience of the illusion and proprioceptive drift are discussed

In recent years consciousness has become a significant area of study in the cognitive sciences. The Frontiers of Consciousness is a major interdisciplinary exploration of consciousness. The book stems from the Chichele lectures held at All Souls College in Oxford, and features contributions from a 'who's who' of authorities from both philosophy and psychology. The result is a truly interdisciplinary volume, which tackles some of the biggest and most impenetrable problems in consciousness. The book includes chapters considering the apparent explanatory gap between science and consciousness, our conscious experience of emotions such as fear, and of willed actions by ourselves and others. It looks at subjective differences between two ways in which visual information guides behaviour, and scientific investigation of consciousness in non-human animals. It looks at the challenges that the mind-brain relation presents for clinical practice as well as for theories of consciousness. The book draws on leading research from philosophy, experimental psychology, functional imaging of the brain, neuropsychology, neuroscience, and clinical neurology. Distinctive in its accessibility, authority, and its depth of coverage, Frontiers of Consciousness will be a groundbreaking and influential addition to the consciousness literature

In this paper, I define tacit knowledge as a kind of causal-explanatory structure, mirroring the derivational structure in the theory that is tacitly known. On this definition, tacit knowledge does not have to be explicitly represented. I then take the notion of a modular theory, and project the idea of modularity to several different levels of description: in particular, to the processing level and the neurophysiological level. The fundamental description of a connectionist network lies at a level between the processing level and the physiological level. At this level, connectionism involves a characteristic departure from modularity, and a correlative absence of syntactic structure. This is linked to the fact that tacit knowledge descriptions of networks are only approximately true. A consequence is that strict causal systematicity in cognitive processes poses a problem for the connectionist programme
