Contre une interprétation déconstructiviste de la question de l'animalité, on s'attache à montrer, par une présentation précise des objections adressées à P. Singer par G. Francione, que l'éthique animale « classique » comporte en elle-même les ressources d'une pensée critique extrêmement audacieuse.

Goffi and Roux are interested in what makes some thought experiments work, while others do not work. They do not attempt to draw an a priori line between two types of thought experiments, but rather ask the following question: inasmuch as thought experiments are arguments, and notwithstanding the fact that some of them might involve the contemplation of an imaginary scenario, how is it that some of them work, while others do not? Taking inspiration from a counterfactual thought experiment (...) presented by Nicholas Rescher, they treat thought experiments as argumentative procedures resembling tests of consistency, which invite the experimenter to seek the weakest link in her body of beliefs. Equipped with this method, they examine two well-known successful thought experiments (Galileo’s two bodies strapped together, and Thomson’s violinist) and discuss Mach’s notion of thought experiments. Thus they reach the hypothesis that successful thought experiments respect the three following conditions: they do not deal with things, but with beliefs; they mobilise a set of beliefs shared by the interlocutors; and this set of beliefs has a hierarchical structure. Using once again examples written at different periods and taken from various disciplines (Descartes’ receding bodies, Aristotle’s weaving shuttles), Goffi and Roux argue that each of those conditions is individually necessary for a thought experiment to work. They finally conclude on the limits and consequences of their approach. (shrink)

French ethics of technology has followed a most peculiar path. Generally speaking, French philosophers of technology have dismissed the methodology of Applied Ethics as widely practiced. As a result, the most notorious thinkers have been those who have expressed the most considerable reservations about the “technical phenomenon.” I here attempt to establish that the most promising attempts to overcome this situation do not rise from social philosophy, but from a long-standing French tradition in the field of philosophy of life, supported (...) by an overriding project of integration of technology into culture.

On se propose de fédérer les questions relevant de la bioéthique, des générations futures et de l’éthique environnementale autour du thème de la communauté morale. On examinera certains problèmes théoriques posés par l’élargissement de celle-ci. On soutiendra qu’il n’est possible d’y faire face qu’en se ralliant à une forme d’anthropocentrisme. Toutefois, il s’agit d’un anthropocentrisme méta-axiologique, pas d’un anthropocentrisme normatif: il ne saurait être question de soutenir que les intérêts des être humains ont, toujours et partout, priorité sur les intérêts (...) des autres créatures.

As it is commonly used, the concept of dignity applies to people as well as to groups of people. It is sometimes supposed to encapsulate such widely different notions as privacy, physical or mental integrity and personality. There is something puzzling in such a situation. This article argues, firstly, that the concept of dignity is best understood when applying ‹only› to autonomy, perfectibility and rationality. Belonging to the language of morals, the concept of dignity has something strongly prescriptive built into (...) it: its function is to justify prohibitions in our ways of dealing with persons. But if interpreted as depending on the actual possession of some capacities, it fails to do its job, because it applies to too few people; and if interpreted as expressing an essence, it fails because it gives way to some form of discrimination. It is suggested that a two-level use of the notion of dignity could improve things, albeit at the cost of trivialising the notion. (shrink)

Après avoir rappelé, à la lumière des analyses de W. N. Hohfeld, ce que peut signifier le concept de droits, on montre que la notion d'obligations envers les générations futures est plus intelligible dans une théorie qui fonde les droits sur la possession d'intérêts que dans une théorie qui les reconduit à l'expression d'une volonté. Cette approche de la question génère toutefois le paradoxe suivant : la génération présente a l'obligation de prendre en compte les intérêts de générations futures sans (...) avoir pour autant l'obligation de faire en sorte qu'il existe des générations futures. On en conclut que les obligations envers les générations futures ne peuvent être que conditionnelles. (shrink)

Il s'agit de déterminer le statut des normes chez les nouveaux casuistes . On indique d'abord quelles sont les circonstances de cette nouvelle casuistique ; on suggère ensuite qu'elle exporte dans le domaine de l'éthique certaines thèses de T. Kuhn, comme le « modèle déductiviste », qu'elle prétend détrôner, s'alimentait au schéma Hempel-Oppenheim de l'explication scientifique. On suggère enfin que les nouveaux casuistes procèdent, de façon plus ou moins radicale, à une naturalisation des normes.It is intented to investigate about the (...) status of norms in the thought of the new casuists . First, the circumstances of the new casuistry are set out; then it is suggested that the new casuists have integrated in their argument concepts from T. Kuhn, just as the “deductivist model” they so sharply criticize integrates concepts from C.G. Hempel and P. Oppenheim. With regard to the initial question, it is shown that the new casuists uphold a kind of norms-naturalizing constructivism. (shrink)

Les animaux peuvent-ils avoir des droits? La souffrance animale a-t-elle une importance morale? Les animaux sont-ils dotes de conscience? Telles sont les questions abordees dans cet ouvrage, qui se propose d'approfondir quelques pistes de reflexion a travers la lecture commentee de deux textes, l'un de John Stuart Mill (extrait de L'utilitarisme), l'autre de Donald Davidson (sur la cognition animale).

Ce livre présente cinq entretiens avec des philosophes pionniers dans le champ de la bioéthique francophone, Anne Fagot-Largeault et Jean-Yves Goff i (France), Gilbert Hottois et Jean-Noël Missa (Belgique) et Marie-Hélène Parizeau (Québec), cinq personnalités de renom, connues pour leur trajectoire exceptionnelle. Les entretiens menés avec ces auteurs au sujet de leurs oeuvres, de leurs expériences dans des comités de bioéthique et des différents débats soulevés ces dernières années nous permettent de connaître leur travail, mais aussi de (...) faire une incursion dans le développement fulgurant de la bio-médecine et des biotechnologies des cinquante dernières années. Les conséquences de ces applications, les problèmes éthiques générés, les jugements favorables et défavorables à l'égard des changements sociaux qui se sont produits et le bouleversement d'idées qui s'en est suivi, sont autant d'aspects abordés dans ces entretiens. L'utilisation du langage courant exige un effort de synthèse important; aussi ces entretiens sous la forme d'une conversation, offrent-ils au lecteur une large vision panoramique, rigoureuse et concise de l'évolution de la bioéthique francophone.

"Christian philosophy" is commonly regarded as an oxymoron, philosophy being thought incompatible with the assumptions and conclusions required by religious faith. According to this way of thinking, philosophy and theology must forever remain distinct. In From Theology to Theological Thinking, Jean-Yves Lacoste takes a different approach. Stepping back from contemporary philosophical concerns, Lacoste--a leading figure in the philosophy of religion--looks at the relationship between philosophy and theology from the standpoint of the history of ideas. He notes in particular (...) that theology and philosophy were not considered separate realms until the high Middle Ages, this distinction being a hallmark of the modern era that is coming to an end. Lacoste argues that the intellectual task before us now is to work in the frontier region between or beyond these domains, work he identifies as "the task of thinking." With this argument, Lacoste resets our understanding of Western Christian thought, contending that a new way of thinking that is at once philosophical and theological will be the lasting discourse of Christianity.

Un mot d'usage quotidien, "danger", est devenu concept chez Heidegger. L'usage heideggerien de "danger" n'est pourtant pas celui de ce livre, qui refuse de s'engager de front dans la "question de l'être" au profit des manières ou modes d'être, dont il explore un échantillon sans prétention exhaustive mais utilisé comme trame heuristique. Mode d'être de l'oeuvre d'art, mode d'être de la "chose" ou du sacrement, mode d'être comme "existence" et comme "vie", un danger est toujours présent : l'existence, telle que (...) décrite chez Heidegger, est déconstituée par des phénomènes auxquels elle ne peut rendre justice ; la vie abrite l'existence mais court le risque perpétuel de n'être que dans les frontières de l'existence, etc. Et si l'étant nous est toujours donné dans un comment - comment de son apparaître, donc comment de son être -, rien ne garantit la pérennité de cette donation : presque tout étant, et d'abord l'étant que nous sommes, est en danger d'apparaître autre qu'il ne nous apparaît maintenant. Aussi convenait-il, après avoir ajointé le concept de vie à celui d'esprit, après avoir dit que la vie est "spirituelle", de justifier le titre du livre en liant "être" et "danger" ; et il restait au final le temps de proposer, dans l'élément du possible, l'hypothèse d'une eschatologie de l'être, avant tout de notre être, sur laquelle le danger n'aurait plus de prise.

The hexagon of opposition is an improvement of the square of opposition due to Robert Blanché. After a short presentation of the square and its various interpretations, we discuss two important problems related with the square: the problem of the I-corner and the problem of the O-corner. The meaning of the notion described by the I-corner does not correspond to the name used for it. In the case of the O-corner, the problem is not a wrong-name problem but a no-name (...) problem and it is not clear what is the intuitive notion corresponding to it. We explain then that the triangle of contrariety proposed by different people such as Vasiliev and Jespersen solves these problems, but that we don’t need to reject the square. It can be reconstructed from this triangle of contrariety, by considering a dual triangle of subcontrariety. This is the main idea of Blanché’s hexagon. We then give different examples of hexagons to show how this framework can be useful to conceptual analysis in many different fields such as economy, music, semiotics, identity theory, philosophy, metalogic and the metatheory of the hexagon itself. We finish by discussing the abstract structure of the hexagon and by showing how we can swing from sense to non-sense thinking with the hexagon. (shrink)

Par-delà toute prise de position idéologique ou politicienne, la réflexion sur l'écologie est devenue de plus en plus présente dans notre société contemporaine, et les musiciens n'ont pas tardé à se sentir fortement concernés, ce qui a suscité, de leur part, des réponses de multiples natures. Certains compositeurs ont cherché à investir des lieux plus ouverts que la traditionnelle salle de concert, tandis que d'autres ont eu recours aux moyens technologiques et médiatiques les plus récents pour capter et diffuser les (...) sons qui nous entourent afin de les reprendre à leur compte ou de dialoguer avec eux, voire les révéler tels quels. La musique ayant de plus en plus tendance à envahir notre quotidien, d'autres encore ont entrepris de créer de nouveaux types d'environnement et de signalétique sonores. Et ces tentatives s'accompagnent fréquemment de confrontations avec différentes disciplines artistiques. L'initiateur d'une telle démarche n'était-il pas Erik Satie avec sa "musique d'ameublement"? Mais qu'aurait-il pensé du matraquage de la Muzak quelques décennies plus tard? (shrink)

This is a collection of new investigations and discoveries on the theory of opposition (square, hexagon, octagon, polyhedra of opposition) by the best specialists from all over the world. The papers range from historical considerations to new mathematical developments of the theory of opposition including applications to theology, theory of argumentation and metalogic.

We define and examine a notion of logical friendliness, which is a broadening of the familiar notion of classical consequence. The concept is tudied first in its simplest form, and then in a syntax-independent version, which we call sympathy. We also draw attention to the surprising number of familiar notions and operations with which it makes contact, providing a new light in which they may be seen.

Pourquoi cet admirable eloge de la phronesis qu'est le Livre VI de l'Ethique a Nicomaque a-t-il donne lieu a tant d'interpretations differentes et meme contradictoires, tant de lectures passionnees et parfois militantes? Peut-etre parce que la maniere propre qu'a Aristote de penser la verite pratique, d'articuler l'intelligence aux circonstances, de l'enraciner dans une culture vivante, reussit une synthese dont nous ne cessons de chercher a percer le secret. Un commentaire continu du Livre VI est suivi ici d'une discussion de quelques (...) questions essentielles et se prolonge en ouvrant quelques perspectives. (shrink)

In his Brouillon Project on conic sections, Girard Desargues studies the notion of traversale, which generalizes that of diameter introduced by Apollonius. One often reads that it is equivalent to the notion of polar, a concept that emerged in the beginning of 19th century. In this article we shall study in great detail the developments around that notion in the middle part of the Brouillon project. We shall in particular show, using the notes added by Desargues after the first draft (...) was written, how here arises a new theory, that of the polarity associated to a conic section. We shall show that besides a natural correspondance between points and lines, Desargues has understood that a conic induces on every line in its plane an involution, and how he progressively handles the considerable conceptual difficulties he has to deal with when trying to explain clearly his novative ideas.

This text is an outgrowth of notes prepared by J. Y. Girard for a course at the University of Paris VII. It deals with the mathematical background of the application to computer science of aspects of logic (namely the correspondence between proposition & types). Combined with the conceptual perspectives of Girard's ideas, this sheds light on both the traditional logic material & its prospective applications to computer science. The book covers a very active & exciting research area, & it will (...) be essential reading for all those working in logic & computer science. (shrink)

Despite its wealth and economic performances, Western Europe is anxious about its future and unable to solve its main problem: unemployment. Its great project is the building or Europe. But many questions have no real answers: how can we avoid social fractures? is globalisation and internationalisation a risk or chance? how should we fight corruption? Europe should be the best answer to those questions. But it depends on the answers to new questions: what are the social values on which we (...) want to build the European society of the next century. Eastern Europe is still poor. But the questions are the same and people are confronted with the same problems. Our common challenge is to build a society for the future. And for the first time of our long history, we have no model. We have to invent it. Firms and managers from Hungary and Eastern Europe have to bring their contribution and promote values and virtues as a major factor of the building of our common Europe. (shrink)
