The paper challenges the assumption, common amongst philosophers, that the reality described in the fundamental theories of microphysics is all the reality we have. It will be argued that this assumption is in fact incompatible with the nature of such theories. It will be shown further that the macro-world of three-dimensional bodies and of such qualitative structures as colour and sound can be treated scientifically on its own terms, which is to say not only from the perspective of psychology but (...) also ontologically. A new sort of emergentist position will be defended, one which yields the basis of a method for describing the perceptually salient macroscopic world in mathematical terms. Broadly, it will be argued that the macroscopic world exists in virtue of certain specific sorts of boundary-patterns in the field of what is captured by the theories of microphysics. (shrink)

Physical reality is all the reality we have, and so physical theory in the standard sense is all the ontology we need. This, at least, was an assumption taken almost universally for granted by the advocates of exact philosophy for much of the present century. Every event, it was held, is a physical event, and all structure in reality is physical structure. The grip of this assumption has perhaps been gradually weakened in recent years as far as the sciences of (...) mind are concerned. When it comes to the sciences of external reality, however, it continues to hold sway, so that contemporary philosophers B even while devoting vast amounts of attention to the language we use in describing the world of everyday experience B still refuse to see this world as being itself a proper object of theoretical concern. Here, however, we shall argue that the usual conception of physical reality as constituting a unique bedrock of objectivity reflects a rather archaic view as to the nature of physics itself and is in fact incompatible with the development of the discipline since Newton. More specifically, we shall seek to show that the world of qualitative structures, for example of colour and sound, or the commonsense world of coloured and sounding things, can be treated scientifically (ontologically) on its own terms, and that such a treatment can help us better to understand the structures both of physical reality and of cognition.

Retention of structure across theory change has been invoked in support of a ‘structural’ alternative to more traditional entity-based scientific realism. In that context the transition from Newtonian mechanics to the Special Theory of Relativity is often regarded as a very significant instance of structural preservation, or retention, associated with correspondence-based recovery. The joint derivation, from a small set of elementary and ontologically neutral assumptions, of both the Galilei and the Lorentz transformation exemplifies the virtues of structural approaches to the (...) foundations of physical theories. The common origination of the resulting two relativistic frameworks sheds light on both the successes and the limitations of correspondence claims. However, the cognitive-operational character of the basic assumptions lends no support to the structural realist’s ‘inference to the best explanation’. (shrink)

An essential feature of the quantum mechanical formalism, entanglement is widely thought to imply nonlocality or nonseparability as a puzzling trait of our ‘quantum world’. The notion of entanglement is reviewed and the question is addressed of whether invoking nonlocal influences, or perhaps time-reversed causation, is warranted in such ‘applications’ as quantum teleportation and entanglement swapping.

Turning away from entities and focusing instead exclusively on ‘structural’ aspects of scientific theories has been advocated as a cogent response to objections levelled at realist conceptions of the aim and success of science. Physical theories whose (predictive) past successes are genuine would, in particular, share with their successors structural traits that would ultimately latch on to ‘structural’ features of the natural world. Motives for subscribing to Structural Realism are reviewed and discussed. It is argued that structural retention claims lose (...) their force if one gives up merely historical readings of the transition from Galilean-relativistic classical mechanics to the ‘special’ theory of relativity, heeding instead basic requirements that lead to their common derivation. Further cause for scepticism is found upon realising that the basic mathematical framework of quantum theory essentially reflects its predictive purpose, without any necessary input, be it of a ‘structural’ kind, from the physical world.

Is quantum mechanics about ‘states’? Or is it basically another kind of probability theory? It is argued that the elementary formalism of quantum mechanics operates as a well-justified alternative to ‘classical’ instantiations of a probability calculus. Its providing a general framework for prediction accounts for its distinctive traits, which one should be careful not to mistake for reflections of any strange ontology. The suggestion is also made that quantum theory unwittingly emerged, in Schrödinger’s formulation, as a ‘lossy’ by-product of a (...) quantum-mechanical variant of the Hamilton-Jacobi equation. As it turns out, the effectiveness of quantum theory qua predictive algorithm makes up for the computational impracticability of that master equation. (shrink)

Réponse à G. Roux ( BCH, 104 [1980], p. 127-149). Le spairistèrion dont l'existence est attestée dans certains gymnases grecs n'est pas un espace hypèthre destiné à la pratique jeux de balle. Ni l'étude architecturale des gymnases de Delphes et de Délos, ni celle des épigraphiques qui s'y rapportent, ni plus généralement nos connaissances sur les jeux ne permettent cette interprétation.

Le mal est un πoλλαχ ς λɛóμɛvov dont les multiples acceptions sont ordonnées selon la division traditionnelle entre le mal naturel ou physique et le mal moral. Le mal naturel désigne la violence que vit et subit l'homme lorsque la nature ou le monde contrecarre sa vie et ses projets: catastrophes naturelles, maladie, souf-france, mort. Ce mal naturel traverse et transit l'existence humaine; dans la mesure où il empêche la réalisation des projets humains et compromet l'ouverture en avant de l'existence (...) humaine, il est ce que Kant nomme anti-final. Le mal est un événement du monde indépendant de la volonté de l'homme. Le mal vient d'un autre et cet autre c'est la nature, le monde ou Dieu. Le mal n'est pas un événement inscrit dans l'horizon de la volonté du sujet mais il est imputé à un autre que soi mais qui a la particularité de conditionner mon être. Le mal est alors un concept de l'être en général, de l'être considéré comme englobant aussi bien l'être que nous sommes nousmêmes que l'être que nous ne sommes pas nous-mêmes. Cependant, cette compréhension du mal n'exclut pas tout lien avec la liberté. (shrink)

The aim of this paper is to address, from a fresh perspective, the question of whether Newtonian mechanics can legitimately be regarded as a limiting case of the special theory of relativity, or whether the two theories should be deemed so radically different as to be incommensurable in the sense of Feyerabend and Kuhn. Firstly, it is argued that focusing on the concept of mass and its transformation across the two varieties of mechanics is bound to leave the issue unsettled. (...) On the one hand, the idea of a speed-dependent ‘relativistic mass’, which has been invoked in support of incommensurability claims, results from a particular, often innocuous but unnecessary and inappropriate reading of certain basic formulae. On the other hand, the existence of an invariant rest mass in STR does not warrant its identification with the Newtonian mass, be it in a suitable limit. This invariant notwithstanding, those who follow Feyerabend and Kuhn can still uphold their views with regard to the two theories. It is shown, however, that the two mechanics embody relativistic frameworks that are direct consequences of the same set of assumptions. As a result, if Newton’s mechanics cannot simply be regarded as a limiting case of STR, the possibility of ‘recovering’ from the latter some elements of the former can be traced to a common source, belying claims of logical disconnection between the two theories.

Although most natural law ethical theories recognize moral absolutes, there is not much agreement even among natural law theorists about how to identify them. The author argues that in order to understand and determine the morality (or immorality) of a human action, it must be considered in relation to the organized system of human practices within which it is performed. Such an approach, he argues, is to be found in the natural law theory of Thomas Aquinas, especially once it is (...) recognized that the logical structure of Aquinas's ethical theory is basically that of an Aristotelian science. In order to depict this structure and to explain how it bears upon the analysis of action, the author investigates a number of issues that have attracted the attention of Thomistic and Aristotelian scholarship. He examines the nature of practical reason, its relationship with theoretical reason, the derivation of lower from higher ethical principles, the incommensurability of human goods, the relationship between will and intellect, and the principle of double effect. The book will be useful to students and scholars interested in ethics, especially from an Aristotelian and/or Thomistic perspective. One appendix reproduces the Leonine text of the De malo (question 6), with facing English translation. Another appendix provides facing Latin text and English translation of the Summa Theologiae I-II (question 94, article 2). ABOUT THE AUTHOR: Kevin L. Flannery, S.J., author of many works on the history of logic--particularly Aristotelian logic--is dean of the faculty of philosophy and professor of the history of ancient philosophy at the Pontifical Gregorian University in Rome. PRAISE FOR THE BOOK: ""I know of no more careful and detailed study of Thomas's principle that the realms of theoretical and practical rationality are parallel. This principle is indeed central to an understanding of Thomas Aquinas's ethical thought, and Father Flannery examines its ramifications most perspicaciously. His book constitutes a valuable and important addition to the Thomistic literature. Father Flannery's writing is lucid, if not always extremely engaging, and his arguments are well supported by references to, and quotations from, the Aristotelian and Thomistic texts upon which they are based.""--The Medieval Review ""It would be hard to overstate the importance of this book at the present juncture of Thomistic studies.""--Ralph McInerny, University of Notre Dame ""... of interest and of great value mostly to specialists in Aquinas's ethics or moral theory more generally. Flannery presents complex matters clearly, and his explanations of the logical presuppositions of Aquinas's moral thought are always illuminating.""--Jean Porter, Theological Studies ""This is a significant work that belongs on the bookshelf of any serious student of Aquinas.... An important contribution to Thomistic studies.""--Irish Theological Quarterly ""This scholastic text will particularly appeal to thinkers interested in Aristotelian mathematics and logic and their practical integration into Thomistic natural law ethics. However, all natural law scholars must address the questions of context and method raised by Flannery's insights and his careful, precise textual analyses."" -- Beverly Whelton, Review of Metaphysics.

This study addresses the nature of the contribution made by Christian feminist thinkers who claim that mutuality is a necessary part of a Christian social ethical framework. The theological method employed is analytical and comparative toward the end of illuminating, testing, and demonstrating the thesis: mutuality is a formal norm for Christian social ethics that functions along with love and justice to promote a balance of power that is required for optimum human flourishing, a flourishing set within the interdependent context (...) of the whole of creation. ;Chapter One analyzes selected primary sources of Rosemary Radford Ruether, Carter Heyward, Beverly Wildung Harrison, and Elizabeth A. Johnson isolating their definition and treatment of the term, "mutuality." A consensus definition of mutuality drawn from definitions by the four feminists. It is concluded that, similar to the tripartite nature of justice, mutuality has four forms--cosmic, gender, generative, and social. ;Chapters Two and Three illustrate several moments in the history of Christian thought wherein antecedents of the feminists' notion of mutuality are found. Selected primary works of Thomas Aquinas, John Duns Scotus, Martin Buber, and H. Richard Niebuhr are examined. ;Chapter Four compares the four feminists' definition of mutuality with definitions of formal norm by Josef Fuchs, Lisa Sowle Cahill, and Timothy E. O'Connell, determining that mutuality is a formal norm for Christian social ethics. Chapter Five is a case study. Utilizing our definition, it is shown how consideration of mutuality and its four forms influences the ethical analyses of George Weigel, Jean Bethke Elshtain, and Stanley Hauerwas in determining if the Persian Gulf War was a just war. It is concluded that the probative value of the formal norm, mutuality, is multifaceted. First and foremost, it requires the moral agent to deal concretely in moral reflection and moral decision-making. Specific and careful attention needs to be given to the reality revealing questions in the concrete, as well as in the abstract. Second, mutuality requires the moral agent to probe the dynamics of power in an ethical dilemma and to seek out ways to shape those dynamics to serve power-with. It is a complement to and corrective of love and justice. Third, engaging the norm of mutuality presses the moral agent toward inclusivity drawing into the process of moral reflection concern for the thriving and flourishing of all involved. More than the norms of love and justice, mutuality places humans in a perspective within the whole of creation. (shrink)

Boorse’s biostatistical theory states that diseases should be defined in ways that reflect disturbances of biological function and that are objective and value free. We use three examples from contemporary medicine that demonstrate the complex issues that arise when defining the boundaries of disease: polycystic ovary syndrome, chronic kidney disease, and myocardial infarction. We argue that the biostatistical theory fails to provide sufficient guidance on where the boundaries of disease should be drawn, contains ambiguities relating to choice of reference class, (...) and is out of step with medical processes for identifying disease boundaries. Although proponents of the biostatistical theory might regard these practical issues as irrelevant to the aim of providing a theoretical account of disease, we take them to indicate the need for a theoretical account that is adequate for current needs—including limiting new forms of medicalization that are driven by the identification of disease based on dysfunction. Our processes for determining the boundaries for disease need to recognize that there is no value-free method for making these decisions. (shrink)

In this paper, The author discusses rawls's recent argument that the aim of political philosophy is not the pursuit of truth but of "free agreement, Reconciliation through public reason" designed to forge an "overlapping consensus." although the author is prepared to agree that political philosophy should sometimes have this goal, She maintains that there are metaphysical commitments about the nature of human beings underlying philosophy itself which commit the political philosophers to pursuing conditions of freedom and equal respect for all, (...) A pursuit which may fail to create--Even undermine--An overlapping consensus in a community. (shrink)

This paper examines the characteristics of infectious diseases that raise special medical and social ethical issues, and explores ways of integrating both current bioethical and classical public health ethics concerns. Many of the ethical issues raised by infectious diseases are related to these diseases’ powerful ability to engender fear in individuals and panic in populations. We address the association of some infectious diseases with high morbidity and mortality rates, the sense that infectious diseases are caused by invasion or attack on (...) humans by foreign micro‐organisms, the acute onset and rapid course of many infectious diseases, and, in particular, the communicability of infectious diseases. The individual fear and community panic associated with infectious diseases often leads to rapid, emotionally driven decision making about public health policies needed to protect the community that may be in conflict with current bioethical principles regarding the care of individual patients. The discussion includes recent examples where dialogue between public health practitioners and medical‐ethicists has helped resolve ethical issues that require us to consider the infected patient as both a victim with individual needs and rights and as a potential vector of disease that is of concern to the community.

That all subjunctive conditionals with true antecedents and trueconsequents are themselves also true is implied by every plausibleand popularly endorsed account. But I am wary of endorsing thisimplication. I argue that all presently endorsed accounts fail tocapture the nature of certain subjunctive conditionals in contextsof consequentialist reasoning. I attempt to show that we must allowfor the possibility that some subjunctive conditionals with trueantecedents and true consequents are false, if we are to believethat certain types of straightforward consequentialist reasoningare coherent. I (...) begin by evaluating a pair of morally releventcounterfactuals in a case via David Lewis's account. I then turnto a slight modification of the case, arguing that Lewis'ssemantics fails to generate the correct truth values of thesubjunctive conditionals in the modified case. Finally, I presenta modified version of Lewis's semantics that generates the correctresults in all of the cases. (shrink)

Down syndrome (DS) impacts several brain regions including the hippocampus and surrounding structures that have responsibility for important aspects of navigation and wayfinding. Hence it is reasonable to expect that DS may result in a reduced ability to engage in these skills. Two experiments are reported that evaluated route-learning of youth with DS, youth with intellectual disability (ID) and not DS, and typically developing (TD) children matched on mental age (MA). In both experiments, participants learned routes with eight choice point (...) presented via computer. Several objects were placed along the route that could be used as landmarks. Participants navigated the route once with turn indicators pointing the way and then retraced the route without them. In Experiment 1 we found that the TD children and ID participants performed very similarly. They learned the route in the same number of attempts, committed the same number of errors while learning the route, and recalled approximately the same number of landmarks. The participants with DS performed significantly worse on both measures of navigation (attempts and errors) and also recalled significantly fewer landmarks. In Experiment 2, we attempted to reduce TD and ID vs DS differences by focusing participants’ attention on the landmarks. Half of the participants in each group were instructed to identify the landmarks as they passed them the first time. The participants with DS again committed more errors than the participants in the ID and TD groups in the navigation task. In addition, they recalled fewer landmarks. While landmark identification improved landmark memory for both groups, it did not have a significant impact on navigation. Participants with DS still performed more poorly than did the TD and ID participants. Of additional interest, we observed that the performance of persons with DS correlated with different ability measures than did the performance of the other groups. The results the two experiments point to a problem in navigation for persons with DS that exceeds expectations based solely on intellectual level. (shrink)

Introduction. Il est bien connu que la correspondance de Curry-Howard permet d'associer un programme, sous la forme d'un λ-terme, à toute preuve intuitionniste, formalisée dans le calcul des prédicats du second ordre. Cette correspondance a été étendue, assez récemment, à la logique classique moyennant une extension convenable du λ-calcul. Chaque théorème formalisé en logique du second ordre correspond donc à une spécification de programme.Il se pose alors le problème, en général tout à fait non trivial, de trouver la spécification associée (...) à un théorème donné; autrement dit, de déterminer le comportement opérationnel commun aux λ-termes associés aux diverses démonstrations formelles du théorème considéré.Cette question est résolue ici pour le théorème de complétude de la logique classique.La première étape consiste à formaliser convenablement ce théorème en logique du second ordre. Ce travail est fait complètement dans la section 1. Il a comme sous-produit, peut-être inattendu, de montrer que ce théorème est prouvable en logique intuitionniste du second ordre. Ceci, toutefois, à condition d'introduire une légère variante de la notion de modèle, en admettant un modèle supplémentaire trivial, où toute formule est satisfaite.On notera, à ce sujet, que des preuves intuitionnistes du théorème de complétude de la logique intuitionniste, utilisant des variantes de la notion de modele de Kripke, ont été données par H. Friedman [7] et W. Veldman [8]. On remarquera également qu'un argument de G. Kreisel [2] montre que le théorème de complétude habituel de la logique intuitionniste n'a pas de preuve intuitionniste.

Ludics [1] is a novel approach to logic—especially proof-theory. The present introduction emphasises foundational issues.For ages, not a single disturbing idea in the area of “foundations”: the discussion is sort of ossified—as if everything had been said, as if all notions had taken their definite place, in a big cemetery of ideas. One can still refresh the flowers or regild the stone, e.g., prove technicalities, sometimes non-trivial; but the real debate is still: this paper begins with an autopsy, the autopsy (...) of the foundational project.Up to say 1900, the realist/dualist approach to science was dominant; during the last century some domains like physics evolved so as to become completely anti-realist; but this evolution hardly concerned logic.By the turn of the XXth century mathematics was jeopardised by paradoxes, the most famous of them being due to Russell. Hilbert's reaction was to focus on consistency. But the reduction of paradoxes—and therefore of foundations—to solely the antinomies is highly questionable: indeed, the typical paradoxical artifacts are secret sharers, objects satisfying the formal definitions but far astray from the intended meaning, typically the Peano “curve” which contradicts our perception of dimension. Fortunately, topology has been able to show that dimension m is not the same as dimension n … but just for a second, forget this and imagine consistent mathematics in which balls in any dimension are homeomorphic: what a disaster! This exclusive focus on consistency—not to speak of the strategic failure of the Programme—should explain why logic, especially foundations lost contact with other sciences during last century.

This paper argues for a largely unnoted distinction between relational and modal components in the lexical semantics of verbs. Wehypothesize that many verbs encode two kinds of semantic information:a relationship among participants in a situation and a subset ofcircumstances or time indices at which this relationship isevaluated. The latter we term sublexical modality.We show that linking regularities between semantic arguments andsyntactic functions provide corroborating evidence in favor of thissemantic distinction, noting cases in which the semantic groundingof linking through participant-role properties (...) apparently fails. Thissemantic grounding can be preserved, however, once we abstractaway from sublexical modality in lexical semantic representations.Semantically-based linking constraints are insensitive to the sublexicalmodality component of lexical entries and depend only on informationin a predicator's situational core.

This paper is an attempt to clarify and assess Dennett’s opinion about the relevance of the phenomenological tradition to contemporary cognitive science, focussing on the very idea of a phenomenological investigation. Dennett can be credited with four major claims on this topic: (1) Two kinds of phenomenological investigations must be carefully distinguished: autophenomenology and heterophenomenology; (2) autophenomenology is wrong, because it fails to overcome what might be called the problem of phenomenological scepticism; (3) the phenomenological tradition mainly derived from Husserl (...) is based on an autophenomenological conception of phenomenology, and, consequently, can be of no help to contemporary cognitive science; (4) however, heterophenomenology is indispensable for obtaining an adequate theory of consciousness. In response to Dennett’s analysis, the paper develops two main counterclaims: (1) Although the traditional conception of phenomenology does indeed fit Dennett’s notion of autophenomenology, his sceptical arguments fail to rule out at least the possibility of a modified version of this traditional conception, such as the one defended in Roy et al. (Naturalizing Phenomenology, 1999); (2) the distinction between autophenomenology and heterophenomenology is at any rate misconceived, because, upon closer analysis, heterophenomenology proves to include the essential characteristics of autophenomenology.

Adoration is the second volume of the Deconstruction of Christianity, following Dis-Enclosure. The first volume attempted to demonstrate why it is necessary to open reason up not to a religious dimension but to one transcending reason as we have been accustomed to understanding it; the term "adoration" attempts to name the gesture of this dis-enclosed reason. -/- Adoration causes us to receive ignorance as truth: not a feigned ignorance, perhaps not even a "nonknowledge," nothing that would attempt to justify the (...) negative again, but the simple, naked truth that there is nothing in the place of God, because there is no place for God. The outside of the world opens us in the midst of the world, and there is no first or final place. Each one of us is at once the first and the last. Each one, each name. And our ignorance is made worse by the fact that we do not know whether we ought to name this common and singular property of all names. We must remain in this suspense, hesitating between and stammering in various possible languages, ultimately learning to speak anew. -/- In this book, Jean-Luc Nancy goes beyond his earlier historical and philosophical thought and tries to think-or at least crack open a little to thinking-a stance or bearing that might be suitable to the retreat of God that results from the self-deconstruction of Christianity. Adoration may be a manner, a style of spirit for our time, a time when the "spiritual" seems to have become so absent, so dry, so adulterated. -/- The book is a major contribution to the important strand of attempts to think a "post-secular" situation of religion.
