We present a Kripke model for Girard's Linear Logic (without exponentials) in a conservative fashion where the logical functors beyond the basic lattice operations may be added one by one without recourse to such things as negation. You can either have some logical functors or not as you choose. Commutatively and associatively are isolated in such a way that the base Kripke model is a model for noncommutative, nonassociative Linear Logic. We also extend the logic by adding a coimplication operator, (...) similar to Curry's subtraction operator, which is resituated with Linear Logic's contensor product. And we can add contraction to get nondistributive Relevance Logic. The model rests heavily on Urquhart's representation of nondistributive lattices and also on Dunn's Gaggle Theory. Indeed, the paper may be viewed as an investigation into nondistributive Gaggle Theory restricted to binary operations. The valuations on the Kripke model are three valued: true, false, and indifferent. The lattice representation theorem of Urquhart has the nice feature of yielding Priestley's representation theorem for distributive lattices if the original lattice happens to be distributive. Hence the representation is consistent with Stone's representation of distributive and Boolean lattices, and our semantics is consistent with the Lemmon-Scott representation of modal algebras and the Routley-Meyer semantics for Relevance Logic.

O. The idea of scientific progress in contemporary philosophy of science. Explicating the concept of cognitive progress means at the same time articulating an ideal of science. A desirable ideal: explain a lot and offer certainty. 1. Working out the ideal with the "foundationalist-positivist" approach. If the question, "When is it rational to accept a theory?" is answered, "When it has sufficient inductive support," this leads to insoluble problems. Reactions to the collapse of this approach - especially relativism and theory (...) instrumentalism. 2. The Popperian alternative: rational theory preference despite fallibility of methods for determining truth or greater accuracy of representations. What good reasons can there be for the conjecture that one theory is superior to a competing theory in its achievement as a description? Achievements to date as fallible but objective indicators of strength in describing. The sorts of risks for a theory differ in explanation and in prediction. Corresponding to the risks are the chances for cognitive progress. Instead of a cumulative index, itemized indication of success and failure in explanation and prediction with regard for importance of the questions at issue. On the concept of the "scientific importance" of questions. Postscript: On the political consequences of the sceptical position in philosophy of science. (shrink)

This paper notes the apparent ineffectiveness of the critical response to competence-based education and training (CBET) and suggests that this results from a failure to correctly isolate CBET's unique, identifying features. It is argued that the prevailing tendency to identify CBET with ‘competence’ is fundamentally mistaken and that the competence approach is more properly characterised in terms of its philosophically naïve methodological strategy. It is suggested that this strategy is based upon untenable assumptions relating to the semantic status of statements (...) of outcome and the epistemological and ontological constructs to which such statements are intended to correspond.

In lieu of an abstract, here is a brief excerpt of the content:In Memory Thomas FarrellOn June 12, 2006, Thomas Farrell died after a long illness. Tom was Professor of Communication Studies at Northwestern University and a long-standing member of the journal's editorial board. He was appointed by the journal's founding editor, Henry Johnstone, and Henry regarded him as among the most talented minds writing about our common subject. Tom also was a publishing author in Philosophy and Rhetoric. His research (...) refl ected a deep understanding of the intersections of philosophical thought and rhetoric with respect to argumentation, language, speech acts, and political theory. His award-winning book, Norms of Rhetorical Culture (Yale, 1993), is a testament to the insights afforded by the rapprochement between philosophy and rhetoric that has been the journal's defi ning character. With his passing, the inter-discipline has lost one of its most eloquent and accomplished voices, the journal has lost a contributor and editorial advisor of the first rank, and those of us who knew Tom have lost a dear friend, whose intellect and wit always brightened our moments together.Copyright © 2006 The Pennsylvania State University...

By appealing to the religious imagination Theology can make a distinctive contribution to business ethics. In the first part of the essay I examine what is entailed by appealing to the imagination to reason in ethics: through converging arguments the imagination enables us rationally to interpret reality and to infer obligations. In the following sections I consider the relevance of the religious imagination for business ethics. In the second part I explain the imagination''s use of religious metaphor to establish its (...) theological distinctiveness in ethical inquiry. Then in the final part I illustrate Theology''s contribution to business ethics by studying the imagination''s use of religious metaphor with regard to profit and to third world debt. (shrink)

Ce texte vise à recomposer l'unité du système de représentations de l'économie, proposé par la télévision française. Cette unité serait régie autant par l'imprévisible que par les règles constitutives du réalisme en économie.This text aims to reconstruct the unity of the system of representations of the economy, proposed by French television. This unit would be governed as much by unpredictable as the rules constitutive of realism in economics.

In lieu of an abstract, here is a brief excerpt of the content:Direct Nuclear Reprogramming: Response to Condic, Lee, and GeorgeGerard Magill, Ph.D. and William B. NeavesWe read with great interest the response of Maureen Condic, Patrick Lee, and Robert George (2009) to our essay, “Ontological and Ethical Implications of Direct Nuclear Reprogramming” in the March 2009 issue of the Kennedy Institute of Ethics Journal (Magill and Neaves 2009). Much of their response addressed issues that are not in dispute: somatic (...) cells are not zygotes, neurons and hepatocytes are different, growth-factor signals from the trophoblast influence development of the inner cell mass, membranes derived from the trophectoderm are critically required for embryonic survival, and stem cells cannot produce a fetus “on their own.”The crucial point of disagreement deals with the fact that iPS cells are not totipotent but zygotes are. Zygotes can generate their own placental structures while iPS cells must be given them through tetraploid complementation. Condic, Lee, and George consider totipotency to be crucial to natural potentiality. We present an alternative view in our essay (Magill and Neaves 2009, pp. 28–29). Placental structures make no lasting contribution to the postnatal organism, and the equivalency of iPS cells with the inner cell mass of the blastocyst is apparent from tetraploid complementation experiments.The respondents acknowledge the following:... somatic cells can be “converted” into zygotes by the process of somatic cell nuclear transfer (SCNT) or direct reprogramming in combination with tetraploid complementation—just as sperm and egg cells can be “converted” into a zygote by the process of natural fertilization—....(Condic, Lee, and George 2009, p. 35)As the respondents recognize, different ways of manipulating cells can lead to embryogenesis: sperm and egg cells in the process of natural fertilization, the enucleated egg and an ordinary body cell in the process of somatic cell nuclear transfer, and reprogrammed skin cells and a tetraploid blastocyst in the case of induced pluripotent stem (iPS) cells. In each case, different cells are manipulated—or “converted” in the respondents’ terminology—in a process that alters their biological fate within a supportive environment facilitating embryogenesis.The developmental potential that resides in the human genome does not unfold in isolation, not even in a zygote. In all cases, whether involving a zygote or an iPS cell, interaction with a supportive environment is required to express the developmental program residing in the genome. [End Page 201]This biological reality supports what we have described as “early cellular development along the continuum of natural potentiality that can result in the formation of a fetus” (Magill and Neaves 2009, p. 30), and it presents a significant challenge to the natural potentiality argument.Gerard MagillVernon F.

“This book will certainly prove to be a useful resource and reference point … a good addition to anyone’s bookshelf.” Network "This is a superb collection, expertly presented. The overall conception seems splendid, giving an excellent sense of the issues... The selection and length of the readings is admirably judged, with both the classic texts and the few unpublished pieces making just the right points." William Outhwaite, Professor of Sociology, University of Sussex "... an indispensable book for all of us (...) in philosophy and the social sciences who teach and care about the shape of social knowledge in the future." Steven Seidman, Professor of Sociology, State University of New York Albany "For a comprehensive account of the ways in which world transformations affect claims to social scientific knowledge, one need look no further than Gerard Delanty and Piet Strydom's Philosophies of Social Science . ...this collection captures nicely the increasingly engaged political nature of the philosophy of social science. Debates about pragmatism, feminism and postmodernism are particularly well represented" The Australian What is social science? How does it differ from the other sciences? What is the meaning of method in social science? What is the nature and limits of scientific knowledge? This collection of over sixty extracts from classic works on the philosophy of social science provides an essential textbook and a landmark reference in the field. It highlights the work of some of the most influential authors who have shaped social science. The texts explore the question of truth, the meaning of scientific knowledge, the nature of methodology and the relation of science to society, including edited extracts from both classic and contemporary works by authors such as Emile Durkheim, Georg Simmel, Max Weber, Alfred Schutz, Max Horkheimer, Jurgen Habermas, Alvin Gouldner, Karl-Otto Apel, Michel Foucault, Pierre Bourdieu, Anthony Giddens, Dorothy Smith, Donna Haraway, Sigmund Freud, Jacques Derrida and Claude Levi-Strauss. The readings are representative of the major schools of thought, including European and American trends in particular as well as approaches that are often excluded from mainstream traditions. From a teaching and learning perspective the volume is strengthened by extensive introductions to each of the six sections, as well as a general introduction to the reader as a whole. These introductions contextualise the readings and offer succinct summaries of them. This volume is the definitive companion to the study of the philosophy of social science, taught within undergraduate or postgraduate courses in sociology and the social sciences. (shrink)

The main purpose of this second article devoted to T. Piketty’s Capital in the Twenty-First Century (the first was published in the previous issue of Actuel Marx) is to introduce our alternative reading of history. The tendencies manifest during the last decades of the 20th century and the early 21st century are not, it is argued, the replication of the tendencies which prevailed prior to World War I. The starting-point for our analysis is the beginning of the 20th century, a (...) moment characterized by the dynamics of a “managerial capitalism” built around the “tripolar” class pattern of capitalists, managers, and popular classes. The main quantitative manifestation of these trends was the steady rise in the share accounted for by wages (compared to capital income) in the income of upper classes (notably the top 1 percent). In place of Piketty’s impact of shocks, we focus on the chain of successive configurations of class domination and alliances, in a succession of “social orders” marking the historical advance of managerial capitalism : the first financial hegemony, in the years leading up to the Great Depression ; the postwar social-democratic compromise ; and its successor, neoliberalism, involving a new alliance to the right, between the managerial and popular classes.

Adam and Eve’s theft marks the beginning of the human career as moral agents. This article will examine the assumptions underlying the notion of moral agency from the perspective of three unremarkable human beings who found themselves in situations of moral difficulty. The article will conclude that these three people could not have acted differently than they did. It will conclude that it is unreasonable to assume that ordinary human beings will inevitably possess the resources to address difficult moral decisions.

The world is beginning to look askance at Science. Or, rather, not beginning but intensifying an attitude of suspicion if not of downright hostility. We scientists are, of course, partly to blame; for we have so loudly proclaimed our virtues as the creators of radios and airplanes that, now these instruments are being abused as agents of mass propaganda and mass destruction, we are the obvious targets for the rising wrath of men. This is serious, for science is inseparably a (...) part of the society and culture in which it is embedded, and it does not suffice to deny impatiently ourguilt and shrug away our responsibility to our fellows.

For the contemporary reader of Psychoanalysis: Its Image and Its Public the analyses of communicative systems in the book provides a challenging occasion for reconsidering current social psychological thinking about the character of social groups. In Moscovici's careful delineation of the communicative systems of diffusion, propagation and propaganda through his content analysis of the French press, one can also see the description of different types of group structured through distinctive social psychological organisations. Moscovici himself suggests that the genres of diffusion, (...) propagation and propaganda are each linked to the construction of a specific type of social-psychological object, opinion, attitude and stereotype respectively. But one can also identify different forms of affiliation corresponding to each communicative genre, and consequently also different representations of the people who constitute both the in-group and the out-group in each instance. The affiliative bonds might be described as forms of sympathy, communion and solidarity. (shrink)

This book is a systematic study of religious morality in the works of John Henry Newman (1801-1890). The work considers Newman's widely discussed views on conscience and assent, analyzing his understanding of moral law and its relation to the development of moral doctrine in Church tradition. By integrating Newman's religious epistemology and theological method, the author explores the hermeneutics of the imagination in moral decision-making: the imagination enables us to interpret complex reality in a practical manner, to relate belief with (...) action. The analysis bridges philosophical and religious discourse, discussing three related categories. The first deals with Newman's commitment to truth and holiness whereby he connects the realm of doctrine with the realm of salvation. The second category considers theoretical foundations of religious morality, and the third category explores Newman's hermeneutics of the imagination to clarify his view of moral law, moral conscience, and Church tradition as practical foundations of religious morality. The author explains how secular reason in moral discernment can elicit religious significance. As a result, Church tradition should develop doctrine and foster holiness by being receptive to emerging experiences and cultural change. John Henry Newman was a highly controversial figure and his insightful writings continue to challenge and influence scholarship today. This book is a significant contribution to that scholarship and the analysis and literature comprise a detailed research guide for graduates and scholars. (shrink)

This brief article comments on Moshe Lewin’s last book (Le siècle soviétique, Fayard, Paris, 2003). The book can be considered as the best documented study of Soviet Union. Lewin’s characterisation of the soviet system as bureaucratic absolutism is, however, disappointing, and contrasts with the identification of the new “managerial” ruling class, its grip on resourses and state power.

The blood oxygen level dependent effect that provides the contrast in functional magnetic resonance imaging has been demonstrated to affect the linewidth of spectral peaks as measured with magnetic resonance spectroscopy and through this, may be used as an indirect measure of cerebral blood flow related to neural activity. By acquiring MR-spectra interleaved with frames without water suppression, it may be possible to image the BOLD effect and associated metabolic changes simultaneously through changes in the linewidth of the unsuppressed water (...) peak. The purpose of this study was to implement this approach with the MEGA-PRESS sequence, widely considered to be the standard sequence for quantitative measurement of GABA at field strengths of 3 T and lower, to observe how changes in both glutamate and GABA levels may relate to changes due to the BOLD effect. MR-spectra and fMRI were acquired from the occipital cortex of 20 healthy participants whilst undergoing intrascanner visual stimulation in the form of a red and black radial checkerboard, alternating at 8 Hz, in 90 s blocks comprising 30 s of visual stimulation followed by 60 s of rest. Results show very strong agreement between the changes in the linewidth of the unsuppressed water signal and the canonical haemodynamic response function as well as a strong, negative, but not statistically significant, correlation with the Glx signal as measured from the OFF spectra in MEGA-PRESS pairs. Findings from this experiment suggest that the unsuppressed water signal provides a reliable measure of the BOLD effect and that correlations with associated changes in GABA and Glx levels may also be measured. However, discrepancies between metabolite levels as measured from the difference and OFF spectra raise questions regarding the reliability of the respective methods. (shrink)

This the first part of a study (in two parts) devoted to Piketty’s theses on the history of capitalism. A summary of Pikety’s analysis is first presented, concerning the dynamics of total wealth (measured as a ratio to national income) and its components, and the tendency of wealth and income inequalities within major capitalist countries. The amplitude of the fall of total wealth in the United-Kingdom and France during World War I is questioned. Piketty explains the profile of these variables (...) concerning wealth and wealth inequalities in reference to historical mechanisms in which the rate of growth of output, the rate of savings, and the return on wealth are considered. The relevance of these mechanisms is basically questioned. We interpret the third component of wealth, other domestic capital, as a form of the capital of enterprises and substitute an alternative, more performing, model to account for the profile of this variable.

Son of a North German businessman, Thomas Mann chose as theme for his early narrative work the conflict between the standards and values of business and those of the artist-writer.Buddenbrooks andTonio Kröger exhibit the tension of values in opposite ways. InThe Magic Mountain, Mann expands his canvas to include military as well as business values in their relation to the creative potential in a young engineer who exiles himself to an Alpine tuberculosis sanatorium to enjoy a unique educational experience. Mann (...) believed that the businessman, like the artist, had a light and dark side, committed by the Protestant ethic, yet bound to entrepreneurial standards of utility and profit. On that account, the businessman, like the creative artist, may experience a certain alientation from ‘Life’. (shrink)

Globalization is more than an economic or geopolitical matter; it is above all a new culture and, as such, it requires philosophical inquiry to determine if it represents a 20th century revolution in thinking not unlike the Kantian Revolution represented to the 18th century. Critical Cosmology takes up the task of establishing the much needed philosophical tools to 'think' globalization by reading Kant's refoundation of cosmopolitanism as a political, not moral, text.
