It is well established that neural grafts can exert functional effects on the host animal by a multiplicity of different mechanisms – by diffuse release of trophic molecules, neurohormones, and deficient neurotransmitters, as well as by growth and reformation of neural circuits. Our challenge is to understand how these different mechanisms complement each other.

The principal temptation toward substance dualisms, or otherwise incorporating a question begging homunculus into our psychologies, arises not from the problem of consciousness in general, nor from the problem of intentionality, but from the question of our awareness and understanding of our own mental contents, and the control of the deliberate, conscious thinking in which we employ them. Dennett has called this "Hume's problem". Cognitivist philosophers have generally either denied the experiential reality of thought, as did the Behaviorists, or have (...) taken an implicitly epiphenomenalist stance, a form of dualism. Some sort of mental duality may indeed be required to meet this problem, but not one that is metaphysical or question begging. I argue that it can be solved in the light of Paivio's "Dual Coding" theory of mental representation. This theory, which is strikingly simple and intuitive (perhaps too much so to have caught the imagination of philosophers) has demonstrated impressive empirical power and scope. It posits two distinct systems of potentially conscious representations in the human mind: mental imagery and verbal representation (which is not to be confused with 'propositional' or "mentalese" representation). I defend, on conceptual grounds, Paivio's assertion of precisely two codes against interpretations which would either multiply image codes to match sense modes, or collapse the two, admittedly interacting, systems into one. On this basis I argue that the inference that a conscious agent would be needed to read such mental representations and to manipulate them in the light of their contents can be pre-empted by an account of how the two systems interact, each registering, affecting and being affected by developing associative processes within the other.

Alice Crary claims that “the standard view of the bearing of Wittgenstein's philosophy on ethics” is dominated by “inviolability interpretations”, which often underlie conservative readings of Wittgenstein. Crary says that such interpretations are “especially marked in connection with On Certainty”, where Wittgenstein is represented as holding that “our linguistic practices are immune to rational criticism, or inviolable”. Crary's own conception of the bearing of Wittgenstein's philosophy on ethics, which I call the “intrinsically-ethical reading”, derives from the influential New Wittgenstein school (...) of exegesis, and is also espoused by James Edwards, Cora Diamond, and Stephen Mulhall. To my eyes, intrinsically-ethical readings present a peculiar picture of ethics, which I endeavour to expose in Part I of the paper. In Part II I present a reading of On Certainty that Crary would call an “inviolability interpretation”, defend it against New Wittgensteinian critiques, and show that this kind of reading has nothing to do with ethical or political conservatism. I go on to show how Wittgenstein's observations on the manner in which we can neither question nor affirm certain states of affairs that are fundamental to our epistemic practices can be fruitfully extended to ethics. Doing so sheds light on the phenomenon that I call “basic moral certainty”, which constitutes the foundation of our ethical practices, and the scaffolding or framework of moral perception, inquiry, and judgement. The nature and significance of basic moral certainty will be illustrated through consideration of the strangeness of philosophers' attempts at explaining the wrongness of killing. (shrink)

The 'postmodern condition,' in which instrumentalism finally usurps all other considerations, has produced a kind of intellectual paralysis in the world of education. The authors of this book show how such postmodernist thinkers as Derrida, Foucault, and Lyotard illuminate puzzling aspects of education, arguing that educational theory is currently at an impasse. They postulate that we need these new and disturbing ideas in order to "think again" fruitfully and creatively about education.

The London suicide bombings of July 7, 2005 were partly the revolt of moral earnestness against a liberal society that, enchanted by the fantasy of rationalist anthropology, surrenders its passionate members to a degrading consumerism. The “humane” liberalism variously espoused by Jürgen Habermas, John Rawls, and Jeffrey Stout offers a dignifying alternative; but it is fragile, and each of its proponents looks for allies among certain kinds of religious believer. Stanley Hauerwas, however, counsels Christians against cooperation. On the one hand, (...) he is right to resist, insofar as liberalism illiberally excludes theology from public discourse. On the other hand, not all humane liberalism does this: Stout's, for example, is genuinely polyglot, requiring not a common secularist language but a common ethic of communicating. Such a liberal ethic and its attendant anthropology merit the support of Christians: there may be more to be said about the Kingdom of God than respect, tolerance, and fairness, but there will not be less. The Christian has good theological reasons to expect some concord with other inhabitants of secular space. Ethical distinctiveness is no measure of theological integrity; and neither theology (paceBarth) nor biblical narrative (paceRichard Hays) should be expected to do all of the ethical running. If Christians are to be thorough in their moral theology and intelligible in their public statements, then they must borrow non‐theological material, formulate abstract concepts, and engage in casuistical analysis. Nevertheless, if an anxious insistence on distinctiveness is a mistake, concern for theological integrity is not. When the moral theologian borrows ethical material from elsewhere, he should integrate it into a theological vision structured by the Christian salvation‐historical narrative, which will sometimes modify the meaning of what is incorporated. So in affirming humane, polyglot liberalism, the moral theologian will at the same time make salutary qualifications. One of these is the assertion of the need of liberal institutions to own and promote their moral and anthropological commitments. In such a confessionally liberal society, universities in general, and the Arts and Humanities in particular, would recover their vocation to form citizens in communicative virtues and to offer them a dignifying, morally serious vision of human being that could save future generations from a degrading consumerism on the one hand and violent over‐reaction on the other.

John Dewey stated that ‘[h]owever far apart philosophy and educational theory may later have become, in their beginnings they were strictly identical.' Dewey's ‘progressivism' in Democracy and Education rests on this communion. A self-reflective philosophical education by the community, about the community, for the community, would create the conditions for the advance of social justice. But new progressive ideas championing redistributive justice might appear to be in worryingly short supply. That is one reason, among many, why Philip Kitcher’s The Main (...) Enterprise of the World is to be welcomed. His rethinking about education amounts to a radical re-education of our thinking about social justice, seeking redistribution of wealth, reduction of privilege, and a redefinition of what is valuable for people and planet in regard to production, distribution, and consumption. I will summarize his book and offer critical thoughts on it relating to three themes: the relation of his proposed Deweyan Society to some current and powerful criticisms of Western rationality; his proposals for classrooms; and the extent to which its own pragmatic philosophical justifications are open to deeper philosophical and educational significance.

Against the domination of moral deliberation by rights-talk In Defence of War asserts that belligerency can be morally justified, even while it is tragic and morally flawed. Recovering the early Christian tradition of just war thinking, Nigel Biggar argues in favour of aggressive war in punishment of grave injustice.

One of the most significant philosophical voices of the twentieth century - the philosopher of 'the Other' - Emmanuel Levinas' work offers a challenge to the discipline of anthropology that claims knowledge of the human. Levinasian philosophy considers subjectivity and identity as 'secret'. For him an attempt to document humanity should then be placed in an ethics of ignorance and 'not-knowing' so that 'otherness' can be inspired. Anthropology thus reaches the Levinasian challenge of defining itself as a humanistic science as (...) well as a humanistic documentation of social life. This book endeavours to take Levinasian and anthropological precepts equally seriously and offers tentative conclusions. (shrink)

The concept of “tacit knowledge” as the means by which individuals interpret the “rules” of social interaction occupies a central role in all the major contemporary theories of action and social structure. The major reference point for social theorists is Wittgenstein's celebrated discussion of rule-following in the Philosophical Investigations. Focusing on Giddens' incorporation of tacit knowledge and rules into his “theory of structuration”, I argue that Wittgenstein's later work is steadfastly set against the “latent cognitivism” inherent in the idea of (...) tacit knowledge and tacit rules. I also argue that the idea of tacit knowledge and tacit rules is either incoherent or explanatorily vacuous. (shrink)

Sinnott, Nigel I enjoyed the article on Islam by Dr John Perkins, as it said a number of things that needed saying; but I did at times feel it was a bit too black and white in its approach.

A well-worn French proverb pronounces ‘tout comprendre c’est tout pardonner’ (‘to understand all is to forgive all’). Is forgiveness the inevitable consequence of social scientific understanding of the actions and lives of perpetrators of serious wrongdoing? Do social scientific explanations provide excuses or justifications for the perpetrators of the actions that the explanations purport to explain? In this essay, I seek clarification of these intertwined explanatory and moral questions.

In the recent and not-too-distant past many of our parents, grandparents and forbears believed that a person’s skin colour and physiognomy, gender, or sexuality licensed them being regarded and treated in ways that are now widely recognised as blatantly unjust, disrespectful, cruel and brutal. But the nineteenth, twentieth, and twenty-first centuries have hosted a series of radical changes in attitudes, beliefs, behaviour and institutionalised practices with regard to the fundamental moral equality of what were once seen as different “kinds of (...) people.” This paper explores the social structure of such “moral revolutions,” via the Wittgensteinian- and Kuhnian- inspired concepts moral perception, moral certainty, normal morality, and moral paradigm.

The received understanding of Winch’s critique of social science is that he propounded a radically relativist, anti-explanatory and a-critical conception of the legitimate task of ‘social studies’. This conception is presumed to be predicated upon an extension of Wittgenstein’s critique of philosophy. I argue, against this view, that Winch reads Wittgenstein through a Kantian framework, and that in fact he advanced a rigorously essentialist and universalist picture of ‘social phenomena’. It is Winch’s underlying Kantian metaphysics that has made his ideas (...) attractive to contemporary architects of critical social theory, such as Giddens and Habermas. However, in opposition to the latter, and in spite of his Kantianism, I discern in Winch a genuinely critical attitude towards social understanding. (shrink)

This book uses the philosophy of Wittgenstein as a perspective from which to challenge the idea of a critical social theory, represented pre-eminently by Giddens, Habermas and Bhaskar.

The claim is frequently made that, as cities become loaded up with information and communications technology and a resultant profusion of data, so they are becoming sentient. But what might this mean? This paper offers some insights into this claim by, first of all, reworking the notion of the social as a spatial complex of ‘outstincts’. That makes it possible, secondly, to reconsider what a city which is aware of itself might look like, both by examining what kinds of technological (...) practices are becoming commonplace and by considering the particular case of spatial awareness. In turn, this leads to a third rumination on how cities might become aware as different kinds of sprite, channelling outstincts in spatially variable ways. Whatever the case, it is clear that new technical-artistic interventions are required if these sprites are not to become simply servants of the security–entertainment complex. Some of these interventions are examined in the fourth part of the paper. (shrink)

This book offers a philosophical study of the teacher.

We report a Monte Carlo study examining the effects of two strategies for handling measurement non-invariance – modeling and ignoring non-invariant items – on structural regression coefficients between latent variables measured with item response theory models for categorical indicators. These strategies were examined across four levels and three types of non-invariance – non-invariant loadings, non-invariant thresholds, and combined non-invariance on loadings and thresholds – in simple, partial, mediated and moderated regression models where the non-invariant latent variable occupied predictor, mediator, and (...) criterion positions in the structural regression models. When non-invariance is ignored in the latent predictor, the focal group regression parameters are biased in the opposite direction to the difference in loadings and thresholds relative to the referent group (i.e., lower loadings and thresholds for the focal group lead to overestimated regression parameters). With criterion non-invariance, the focal group regression parameters are biased in the same direction as the difference in loadings and thresholds relative to the referent group. While unacceptable levels of parameter bias were confined to the focal group, bias occurred at considerably lower levels of ignored non-invariance than was previously recognized in referent and focal groups.

Nigel Harris argues that the notion of national capital is becoming redundant as cities and their citizens, increasingly unaffected by borders and national boundaries, take center stage in the economic world. Harris deconstructs this phenomenon and argues for the immense benefits it could and should have, not just for western wealth, but for economies worldwide, for international communication and for global democracy.

This article argues that de Certeau’s understanding of walking as the archetypal transhuman practice of making the city habitable cannot hold in a post-human world. By concentrating on the practices of driving, I argue that other experiences of the city can have an equal validity. In other words, de Certeau’s work on everyday life in the city needs to be reworked in order to take into account the rise of automobility. The bulk of this article is devoted to exploring how (...) that goal might be achieved, concentrating in particular on how new knowledge like software and ergonomics has become responsible for a large-scale spatial reordering of the city which presages an important change in what counts as making the city habitable.

During the past four decades, the Netherlands played a leading role in the debate about euthanasia and assisted suicide. Despite the claim that other countries would soon follow the Dutch legalization of euthanasia, only Belgium and the American state of Oregon did. In many countries, intense discussions took place. This article discusses some major contributions to the discussion about euthanasia and assisted suicide as written by Nigel Biggar, Arthur J. Dyck, Neil M. Gorsuch, and John Keown. They share a (...) concern that legalization will undermine a society's respect for the inviolability and sanctity of life. Moreover, the Report of the House of Lords Select Committee on the Assisted Dying for the Terminally Ill Bill is analyzed. All studies use ethical, theological, philosophical, and legal sources. All these documents include references to experiences from the Netherlands. In addition, two recent Dutch documents are analyzed which advocate further liberalization of the Dutch euthanasia practice, so as to include infants and elderly people "suffering from life".

Sinnott, Nigel The son of a stonemason, Joseph Symes was born at Portland, Dorset, England, on 29 January 1841, a birthday he was proud to share with Thomas Paine. He joined the Wesleyan church in 1858, became a local preacher, and, encouraged by his devout mother, in 1864 entered the Wesleyan College at Richmond-upon-Thames.

This article aims to articulate a set of general principles of a Christian ethic of mass immigration. Toward this end, it considers: biblical and theological grounds for cosmopolitanism (and ‘open borders’); biblical and theological caveats against cosmopolitanism; elements of a Christian ethic of the treatment of near and distant neighbours; what Francisco de Vitoria’s ‘On the American Indians’ has to contribute; what lessons should be learned from the history of European colonialism; and the nature of mass immigration into twenty-first-century Europe (...) and the problems it entails. The article concludes with six principles: relevant empirical data should be mastered before developing a judgement; concerns about mass immigration should not be dismissed out of hand as ‘racist’; care of the alien may take a variety of forms, not only that of granting asylum; illegal economic immigrants should normally be returned home; compassion should look in several directions—not only at the migrant, but also at the working-class competitor for jobs and services, and at members of government burdened with the responsibility of making hard decisions; and the Christian is obliged to exercise, not only compassion, but justice and prudence.

Neurulation, the curling of the neuroepithelium to form the neural tube, is an essential component of the development of animal embryos. Defects of neural tube formation, which occur with an overall frequency of one in 500 human births, are the cause of severe and distressing congenital abnormalities. However, despite the fact that there is increasing information from animal experiments about the mechanisms which effect neural tube formation, much less is known about the fundamental causes of neural tube defects (NTD). The (...) use of computer models provides one way of gaining clues about the ways in which neurulation may be compromised. Here we employ one computer model to examine the robustness of different cellular mechanisms which are thought to contribute to neurulation. The model, modified from that of Odell et al (Odell, G.M., Oster, G., Alberch, P. and Burnside, B., (1981)) mimics neurulation by laterally propagating a wave of apical contraction along an active zone within a ring of cells. We link the results to experimental evidence gained from studies of embryos in which neurulation has been perturbed. The results indicate that alteration of one of the properties of non-neural tissue can delay or inhibit neurulation, supporting the idea, gained from observation of embryos bearing genes which predispose to NTD, that the tissue underlying the neuroepithelium may contribute to the elevation of the neural folds. The results also show that reduction of the contractile properties of a small proportion of the neuroepithelial cell population may have a profound effect on overall tissue profiling. The results suggest that the elevation of the neural folds, and hence successful neurulation, may be vulnerable to relatively minor deficiencies in cell properties. (shrink)

Cholinergic-rich grafts have been shown to be effective in restoring maze-learning deficits in rats with lesions of the forebrain cholinergic projection system. However, the relevance of those studies to developing novel therapies for Alzheimer's disease is questioned.

In recent years there has been growing attention paid to a kind of human action or activity which does not issue from a process of reflection and deliberation and which is described as, e.g., ‘engaged coping’, ‘unreflective action’, and ‘flow’. Hubert Dreyfus, one of its key proponents, has developed a phenomenology of expertise which he has applied to ethics in order to account for ‘everyday ongoing ethical coping’ or ‘ethical expertise’. This article addresses the shortcomings of this approach by examining (...) the pre-reflective ethical know-how individuals first develop and on which all later forms of ethical expertise are dependent. In the first section an account is given of the ‘ethical second nature’ which every individual develops from childhood onwards and which forms the basis of pre-reflective ethical know-how. The acquisition of an ethical second nature early on opens up the very domain of ‘the ethical’ for us in the first place and is constitutive of our sensitivity to it. The second section turns to pre-reflective ethical know-how and whether it is conceptual in nature. Just as sensorimotor understanding forms the basis of our reflective perceptual concepts, pre-reflective ethical know-how is similarly proto-conceptual and is the source of our reflective ethical and moral concepts. Finally, the third section examines the process whereby ethical second nature and pre-reflective ethical know-how are actually acquired, namely, through immersion in an ‘ethical world’. This world consists of both the web of ethical meanings and significances which has evolved in a particular society or community as well as its members whose actions and interactions continually reproduce that web.

Fire is a force that links everyday human activities to some of the most powerful energetic movements of the Earth. Drawing together the energy-centred social theory of Georges Bataille, the fire-centred environmental history of Stephen Pyne, and the work of a number of ‘pyrotechnology’ scholars, the paper proposes that the generalized study of combustion is a key to contextualizing human energetic practices within a broader ‘economy’ of terrestrial and cosmic energy flows. We examine the relatively recent turn towards fossil-fuelled ‘internal (...) combustion’ in the light of a much longer human history of ‘broadcast’ burning of vegetation and of artisanal pyrotechnologies – the use of heat to transform diverse materials. A combustion-centred analysis, it is argued, brings human collective life into closer contact with the geochemical and geologic conditions of earthly existence, while also pointing to the significance of explorative, experimental and even playful dispositions towards energy and matter.
