Leishmania major infection of inbred mice leads to a major dichotomous response—death or survival—that depends on the strain of mice. This finding has motivated efforts to locate genetic determinants of disease susceptibility. Genotyping studies have confirmed a complex multilocus trait, but studies directed at the biology of the response suggest identifiable components of susceptibility that may direct the genetic investigations. A confluence of parasite variables—residence in macrophages, class II-dependent immunity, and avoidance of early IL-12 induction—with host factors—a prominent helper T-cell (...) precursor frequency to a dominant parasite epitope and a bias in IL-4 gene activation—conspires to drive an aberrant immune response in animals that suffer fatal disease. These insights may lead to an understanding of factors that focus responses on dominant antigens and that mold the naive T-cell repertoire. Collectively, such factors might contribute to the pathogenesis of other infectious and autoimmune diseases. BioEssays 21:510–518, 1999. © 1999 John Wiley & Sons, Inc. (shrink)

Four prominent views of the nature and methods of clinical ethics (especially in consultation forums) are reviewed; each is then submitted to a criticism intended to show both weaknesses and strengths. It is argued that clinical ethics needs to be responsive to the specific complexities of clinical situations. For this, the need for an expanded notion of practical reason within unique situations is emphasized, one whose aim is to facilitate decision-making on the part of those directly responsible for them and (...) consonant with their own respective moral frameworks and conceptions of what is most worthwhile.

This article reviews the historical and current controversies about the nature of clinical ethics consultation, as a way to focus on the place and responsibility of ethics consultants within the context of clinical conversation — interpreted as a form of dialogue. These matters are approached through a particularly compelling instance of the controversy that involves several major figures in the field. The analysis serves to highlight very significant questions of the nature and constraints of clinical situations, and the moral responsibility (...) and legal accountability that are especially important for clinical ethics consultants.

Many of the errors that occur in children' subtraction are due to the use of incorrect strategies rather than to the incorrect recall of number facts. A production system is presented for performing written subtraction which is consistent with an earlier analysis of the nature of such a cognitive skill. Most of the incorrect strategies used by schoolchildren can be accounted for in a principled way by simple changes in the production system, such as the omission of individual rules or (...) the inclusion of rules appropriate to other arithmetical tasks. The production system model is evaluated against a corpus of over 1500 subtraction problems done by 10‐year olds and is shown to account for about two‐thirds of the (nonnumber fact) errors. It also provides an alternative, simpler interpretation of the subtraction errors analysed by Brown and Burton (1978). Some implications for teaching are discussed. (shrink)

Richard M Weaver, a thinker and writer celebrated for his unsparing diagnoses and realistic remedies for the ills of our age, is known largely through a few of his works that remain in print. This new collection of Weaver's shorter writings, assembled by Ted J Smith III, Weaver's leading biographer, presents many long-out-of-print and never-before-published works that give new range and depth to Weaver's sweeping thought. Included are eleven previously unpublished essays and speeches that were left in near-final form (...) at the time of Weaver's death in 1963. In all, there are some one hundred and twenty-six essays, speeches, book reviews, and editorials. (shrink)

In an overview of the essays in this project, a number of clinical ethics issues receive emphasis. (1) One cluster concerns the ethical concerns presented within the relationship between the providers (doctor, nurse, etc.) and patient (and family), as distinct from those associated with being a clinical ethics consultant invited into a situation to assist. (2) Distinct from these are ethical issues intrinsic to the ways in which clinical encounters are variously written about (from chart notes to published articles). (3) (...) Finally, there is a set of issues connected with the major characteristics of clinical encounters, in view of which it is imperative to be specifically attentive to the fine details and complex interactions among patient, doctor, family, and others, within a specific social context. Keeping these matters in mind helps to clarify the differences between consulting (talking and listening) and writing about consultations, as well as among the various kinds of writing about clinical encounters.

Our intention here is to present the essential character of classical, sunnī kalām within a strictly formal perspective and to set out its basic aspects. It was conceived by the mutakallimīn as a rational, conceptual, and critical science and, although kalām differed in a number of basic concepts and constructs and in its analytic system, the topical organisation of the major compendia parallels that of metaphysics as understood in the contemporary Aristotelian tradition. The debates between kalām and falsafa need to (...) be examined within this context. Kalām, however, is theological in the strict sense of the term and it is as such that its problematic and its procedures are primarily to be understood. Thus seen, the object of kalām is to rationalise the cognitive content presented to Believers in the symbolic language of the koranic revelation. It has, then, four principal tasks, sc, to conceptualise, to order, to explain, and where possible to justify the primary doctrines of the community whose belief is held to be normative. Within this framework the differences that characterise the major schools as such and the various tendencies of individual masters within each school may readily be brought to light. On se propose ici de présenter, d'un point de vue strictement formel, la nature du kālam classique sunnite et d'identifier ses caractéristiques principales. II avait été conçu par les mutakallimin comme une science rationelle, conceptuelle et critique. L'organisation des matières dans ses traités reprend celle de la métaphysique dans la tradition aristotélicienne de l'époque, bien que le kalām s'en distingue par plusieurs de ses structures et concepts fondamentaux, ainsi que par son système analytique. C'est dans ce contexte qu'il faut considérer les debats qui s'instaurèrent entre kalām et falsafa. Le kalām, cependant, est d'ordre strictement théologique et c'est principalement dans ce cadre qu'il faut comprendre sa problématique et ses procédures. Le kalām a pour fonction de rationaliser le contenu cognitif offert aux croyants dans le langage symbolique de la révélation coranique. Il en résulte quatre tâches principales; il s'agit de conceptualiser, ordonner, expliquer et, dans le mesure du possible, justifier les doctrines principales reconnues par la communauté faisant référence en matière de croyance. Dans ce cadre, il sera possible de mettre en lumière les différences entre les principales écoles, ainsi que les tendances qui distinguent certains de leurs grands maîtres respectifs. (shrink)

After a brief, personal reflection on Aron Gurwitsch's life and his many influences on my career, I devote this lecture to some of the central themes of a phenomenology of medicine. Its core is the clinical encounter, which displays a certain structure I term the asymmetry of power and vulnerability —a complex contextual imbalance characterized by multiple points of view, hence points for reflective entrance. These are then interpreted phenomenologically in terms of epoché and reduction, evidence, reflection, and other related (...) themes. I conclude with a suggestion about "the fundamental method" of phenomenology, free fantasy variation. (shrink)

After expressing gratitude to each contributor, and briefly commenting on each, I probe several main themes of my work, addressing the question of the apparent difference between my earlier philosophical and later clinical writings. Central to both is the reflexivity of the human agent, and that each exhibits a form of practice regardless of the specific aims embedded in each. I then address the theme of narrative writing as my work has developed over the past several decades – at the (...) heart of which are questions of self and integrity. (shrink)

This essay focuses on questions central to Husserl’s essential methodology, specifically his notion of ‘free-fantasy variation,’ which he regarded as his ‘fundamental methodological insight.’ At the heart of this ‘vital element of phenomenology’ is what he often terms ‘as-if experience’ thanks to which anything whatever can be considered either for its own sake or as an example of something else. Further analysis explores the act of exemplification, the act of feigning and the shifts of attention and orientation that ground free-fantasy (...) variation. Exemplification and possibilizing are then examined in daily life to discern what makes the complex act of feigning at all possible. An examination of the phenomenon of upsets brings the core sense of possibilizing to light. A focus on the dramatic force intrinsic to these experiences, and the essential place of reflective awareness inherent to them, makes apparent how the rudimentary sense of self begins to emerge, and there follows an analysis of this self-referentiality of possibilizing. The analysis then concludes with a brief examination of Husserl’s so-called ‘zig-zag’ method of constitutive phenomenology. (shrink)

Tested the 2-process theory of detection, search, and attention presented by the current authors in a series of experiments. The studies demonstrate the qualitative difference between 2 modes of information processing: automatic detection and controlled search; trace the course of the learning of automatic detection, of categories, and of automatic-attention responses; and show the dependence of automatic detection on attending responses and demonstrate how such responses interrupt controlled processing and interfere with the focusing of attention. The learning of categories is (...) shown to improve controlled search performance. A general framework for human information processing is proposed. The framework emphasizes the roles of automatic and controlled processing. The theory is compared to and contrasted with extant models of search and attention. (shrink)

The present study seeks to lay out the most basic elements of the ontology of classical Aš‘arite theology. In several cases this requires a careful examination of the traditional and the formal lexicography of certain key expressions. The topics primarily treated are: how they understood “Being/ existence” and “being/existent” and essential natures; the systematic exploitation of the equivocities of certain expressions within a general context in which other than words there are no universals proves to be elegant as well as (...) insightful; the basic categories of primary entities: independant beings and nonindependant beings, created and uncreated, the equivocity of “being/existent” as predicated of contingent entities on the one hand and of God and His attributes on the other, and certain problems that arise because of the rigid application of the system's underlying analytic principles. Nous essayons ici de presenter les éléments fondamentaux de l'ontologie de l'aš‘arisme classique. Pour quelques expressions, il a fallu examiner la lexicographie et ordinaire et technique pour bien comprendre leur emploi et leur signification. Les sujets examinés sont: le sens de “Etre/existence” et de “être/existant” et le concept de réalité essentielle; l'emploi nuancé des équivocités de quelques expressions dans un contexte où les seuls universaux sont des mots, emploi qui se révèle philosophiquement élégant; les catégories fondamentales des êtres: êtres indépendants et êtres non-indépendants, soit créés soit incréés, l'équivocité de “être/existant” dit des êtres contingents d'une part, de Dieu et ses attributs d'autre part, et enfin quelques difficultiés qui résultent de l'application rigide des principes analytiques du système.

Ethics and the Clinical Encounter explores the moral dimensions of clinical medicine and the phenomenon of illness, to determine what ethics must be in order to be fully responsive to clinical encounters. Written in a lively and conversational style with minimal technical terminology, and enhanced by actual experience or real clinical situations, this volume lays out a clinical ethics methodology both in practical and theoretical terms. Here's what the experts had to say: Professor Zaner has provided us with a remarkably (...) lucid and trenchant discussion of the interface of philosophy and the field of medicine. He brings into play an extraordinary range of historial knowledge, extensive observations based on firsthand experience with medical practices, and an acute sense of philosophical argumentation. This is a work that will be an exemplary and indispensable text in the philosophy of medicine for years to come. -- Calvin Schrag... it is a highly original contribution usable in a number of fields.... It really has no competition.... The genius of Zaner's approach is to ground ethics from the 'bottom up' and to direct us to the concrete particulars of therapeutic encounters wherein lie moral and ethical matters... meaty, challenging, and ultimately rewarding.... -- Paul R. Dokecki Richard M. Zaner founded the Center for Clinical and Research Ethics at Vanderbilt University Medical Center. Having established Vanderbilt's first Hospital Ethics Committee (1985), he served as co-chair of VUMC's Ethics Committee since its inception in 1990. Zaner has published five original books, edited ten, and translated four more, and has published more than 100 sections of books and professional journals. (shrink)

This study takes up the challenge presented to philosophy in a dramatic and urgent way by contemporary medicine: the phenomenon of human life. Initiated by a critical appreciation of the work of Hans Jonas, who poses that issue as well, the inquiry is brought to focus on the phenomenon of embodiment, using relevant medical writing to help elicit its concrete dimensions. The explication of embodiment, aided by critical studies and inquiries into medical phenomena make possible the development of the author’s (...) original phenomenological theory of self, and its concrete relationships with the other self. This study attempts not only to show connections among the works of a number of thinkers in terms of central problems, but to demonstrate the mutual relevance of medicine and philosophy through concrete illustrations and analysis.
