Afin de saisir la portée du débat nord-américain sur les communautarismes pour l’éthique théologique chrétienne actuelle, il paraît nécessaire de faire le point sur la différence entre le communautarisme des traditions intellectuelles, morales et spirituelles partagées, ou communautarisme éthico-religieux et éthico-politique, et le communautarisme politique. Le second, pour autant qu’il postule l’existence de communautés séparées au sein du politique, en est selon nous réduit à échouer comme modèle politique, aussi bien en ce qui concerne la démocratie à l’intérieur des Etats-nations (...) qu’en ce qui touche les relations entre Etats-nations . D. Müller prête ici attention à la valeur herméneutique constructive des traditions intellectuelles, morales et ou spirituelles, et plaide pour la fécondité partielle d’une telle approche lorsqu’il est question de construire une éthique théologique à visée vraiment universelle.To understand the scope of the North American debate on the communitarianisms for Christian theological ethics today, it seems necessary to discuss the difference between the communitarism of shared intellectual, moral and spiritual traditions or ethical-religious and ethical-political communitarianism, and political communitarianism. The latter, insofar as it postulates the existence of separate communities within the political sphere is, in our view, bound to fail as a political model, both as regards democracy inside nation-states , and as regards relations between nation-states . D. Müller is calling attention here to the constructive hermeneutic value of intellectual, moral and spiritual traditions and arguing in favor of the partial fecundity of such an approach when it is a question of constructing a theological ethic with a truly universal outlook.

This article concerns the exact sciences in Byzantium, namely the four traditional sciences that were usually designated in the Middle Ages by the term quadrivium : arithmetic, astonomy, geometry and music. It offers a review of the Byzantine texts and documents preserved in these domains from the sixth century to the Fall of Constantinople. The article presents the leading trends : continuation of Hellenistic Greek science, Islamic Jewish or Latin influences, in practical or scholarly directions, as well as the great (...) historical changes that mark the stages of scientific knowledge. The ancillary sciences, geography, optics and mechanics, as well as astrology, are briefly sketched. (shrink)

Le livre d’Albert Jacquard, « Dieu ? », fait voir à quel point le langage du credo est devenu inintelligible pour des esprits contemporains. Il oblige à s’interroger sur le sens d’une récitation non comprise, à reconnaître la légitimité de textes plus parlants, mais aussi à contester les limites d’une approche purement objectivante du réel. Cela admis, il reste que c’est l’interprétation du contenu même de la foi qui divise aujourd’hui les croyants les plus sincères, alors que leur apport au (...) débat public semble mieux accueilli que naguère. De nouvelles expressions du message chrétien ne pourront se dégager que peu à peu, sans doute à travers maint tâtonnement. (shrink)

Quel est le type de rationalité que peut revendiquer la théologie dans le champ des savoirs ? Pas seulement d’épistémologie, la question prend aujourd’hui une tournure nettement plus utilitaire : qu’est-ce qui justifie le fait que des institutions prestigieuses comme les universités entretiennent encore à grand frais des Facultés dont l’objet même est devenu culturellement marginal ? Craintes illusoires ? Les gestionnaires des universités d’inspiration chrétienne, comme il en existe dans mon pays, vous diront qu’elles ne sont pas dépourvues de (...) fondement. Les urgences en termes humains : là est l’enjeu. Nos sociétés se trouvent face à des défis inédits. La prise de conscience la plus récente est la catastrophe écologique qui nous menace. Et l’écologie n’est pas le seul défi. Nous vivons dans un monde d’inégalités terrifiantes, où sévissent de nombreux espaces de famine, où la violence semble incontrôlable, où les idéologies religieuses qu’on croyait mortes exercent encore des ravages. L’enjeu, ce n’est donc pas la survie d’institutions vénérables, ni même la qualification culturelle de notre digne corporation, mais l’avenir de la planète et de cette espèce de vivants très particulière, les humains. A moins d’être inconscient, le théologien qui essaie de faire son métier dans ce contexte ne peut que s’interroger sur la pertinence de son travail et sur la responsabilité qui est la sienne.What kind of rationality can theology claim in the field of knowledge? No longer solely epistemological, this question today takes on a decidedly more utilitarian turn: what might justify the fact that prestigious institutions such as universities still maintain at great cost departments the only object of which has become culturally marginal? Illusory fears? The administrators of universities of Christian inspiration, as we have in my country, will tell you that these questions are well founded. What is paramount is the urgency of the issues human being must face. Our societies have to cope with previously unheard of challenges, the most recent of which is the realization that we are facing the threat of an ecological catastrophe, and this is not the only one. We live in a world of terrifying inequalities, where many areas are plagued by famine, violence appears uncontrollable, and religious ideologies we thought long past still wreak havoc. What is at stake is thus not the survival of venerable institutions, nor even the cultural qualification of our worthy community of scholars, but the future of the planet and of this very particular species – human beings. Unless they insist on being oblivious to the situation, theologians trying to do their job in this context cannot help but question what the pertinence of their work might be and what their responsibility is.

This paper gives a critical edition of the Treatise on the Easter Computus of Barlaam of Seminara, with a French translation and commentary. Written around 1333 this treatise demonstrates systematically and scientifically why the Easter Canon used at that time by the Church is superseded. Nevertheless Barlaam advises that the usual Canon should not be changed. In spite of its objectivity, Barlaam's treatise must be seen in the context of his rivalry with Nicephorus Gregoras, who had already proposed to modify (...) the Canon. The paper analyses Gregoras' text and gives a comparison with Barlaam's treatise. At the scientific level, both scholars rely on Ptolemy for the date of the spring equinox and the length of the Solar year, but Barlaam introduces a supplementary argument, which is the inexactness of the 19 year cycle.

Quand on s'interroge sur le type de catholicité ou d'universalité qui convient à l'Église à notre époque de mondialisation, il faut prendre pour objectif direct, non le seul profit de l'Église, mais le service de l'Évangile, et pour base de réflexion, non les structures institutionnelles, mais ce qui est déjà en train de germer dans les communautés chrétiennes. La perspective qui se dessine alors est d'ordre anthropologique et non simplement religieuse : la forme évangélique dont l'Église doit témoigner est celle (...) d'un vivre-ensemble fraternel, d'une capacité de relation ouverte à tous, d'un refus de toute exclusion, d'une ouverture à tout l'humain. Cette orientation permet d'esquisser des figures nouvelles d'ecclésialité, ordonnées au service du monde , disséminées dans la société , s'accommodant d'appartenances sélectives et provisoires, appelant un fonctionnement nouveau de l'Église locale et de l'autorité centrale. Ces figures sont à créer, l'Évangile le permet et y pousse ; au terme se laisse entrevoir une œcuménicité décentrée et immergée dans l'histoire des hommes. When we ask ourselves about the kind of catholicity or universality that is fitting for the Church in our age of globalization, we should take for our direct object, not the unique profit of the Church, but the service of the Gospel. And for a basis of reflection, not institutional structure, but that which is already being germinated in Christian communities. Then the perspective that is designed is of an anthropological dimension and not simply religions : the evangelical form that the Church should witness to is that of a fraternal living together, a capacity of relation open to everyone, a refusal of all exclusion, and an opening to all what is human. This orientation allows us to sketch new figures of ecclesiality, ordered to the service of the world , spread throughout society , accommodating itself to selective and provisional belongings, and calling for a new functioning of the local church and of central authority. These figures need to be created ; the Gospel allows for it and encourages it. One can foresee ecumenism as the result, decentralized and emerged in the history of humanity. (shrink)

La diminution rapide du nombre des prêtres en nos régions pose avec urgence la question du gouvernement des communautés chrétiennes, et en particulier celle de la présidence de l’eucharistie qui en fait normalement partie. Le retour aux sources effectué en ecclésiologie et en théologie des sacrements depuis Vatican II invite à reprendre à nouveaux frais la question d’un élargissement des conditions d’accès au ministère de présidence : ordination d’hommes mariés, délégations à durée déterminée, voire cas-limite d’une présidence «charismatique» dans les (...) cas de nécessité. L’article recense les positions d’une série de théologiens qui ont envisagé positivement ce problème et plaide pour qu’on ne limite pas trop vite l’éventail des solutions théologiquement acceptables.

Comment devient-on philosophe? Par quel sursaut un Aristoclès se fait-il Platon, jusqu'à s'imposer dans la liste des " auteurs philo " Il faut enquêter, non pas sur la vie privée, mais sur la vie intime : rumination intellectuelle, ton sur lequel on parle, motivations amoureuses... Ce qui fait un philosophe, c'est un immense travail sur soi, et la rencontre d'autres philosophes, vivants, de leurs problématiques. Mémoire sémantique + obsession métaphysique, voilà le code génétique du philosophe. Il débute par un attentat (...) religieux, puisqu'il commence sa carrière en niant tel ou tel sacré. Bien sûr, il vaut mieux être mâle, communiquer par les livres adopter la langue dominante, écrire quand on est célibataire. Comment gagner sa vie? Pas forcément en étant enseignant, comme c'est le cas aujourd'hui. Le profil du philosophe nous le révèle orphelin, vivant à l'étranger, souvent laid, jamais fou, et serial thinker, prêt à changer de philosophie pourvu qu'il reste, lui, à menacer le monde donnera ou donnera pas du sens à notre vie? Le philosophe est l'être inquiet qui pense inquiéter l'Être par deux trois mots bien aiguisés. (shrink)

While there are numerous doubts, controversies and lack of consensus on alternative definitions of human death, it is argued that it is more ethical to allow people to choose either cessation of cardio-respiratory function or loss of entire brain function as the definition of death based on their own views. This paper presents the law of organ transplantation in Japan, which allows people to decide whether brain death can be used to determine their death in agreement with their family. Arguably, (...) Japan could become a unique example of individual choice in the definition of death if the law is revised to allow individuals choose definition of death independently of their family. It suggests that such an approach is one of the reasonable policy options a country can adopt for legislation on issues related to the definition of death. (shrink)

Extraterrestrial Altruism examines a basic assumption of the Search for Extraterrestrial Intelligence (SETI): that extraterrestrials will be transmitting messages to us for our benefit. This question of whether extraterrestrials will be altruistic has become increasingly important in recent years as SETI scientists have begun contemplating transmissions from Earth to make contact. Technological civilizations that transmit signals for the benefit of others, but with no immediate gain for themselves, certainly seem to be altruistic. But does this make biological sense? Should we (...) expect altruism to evolve throughout the cosmos, or is this only wishful thinking? Is it dangerous to send messages to other worlds, as Stephen Hawking has suggested, or might humankind benefit from an exchange with intelligence elsewhere in the galaxy? Would extraterrestrial societies be based on different ethical principles, or would we see commonalities with Earthly notions of morality? Extraterrestrial Altruism explores these and related questions about the motivations of civilizations beyond Earth, providing new insights that are critical for SETI. Chapters are authored by leading scholars from diverse disciplines—anthropology, astronomy, biology, chemistry, computer science, cosmology, engineering, history of science, law, philosophy, psychology, public policy, and sociology. The book is carefully edited by Douglas Vakoch, Director of Interstellar Message Composition at the SETI Institute and professor of clinical psychology at the California Institute of Integral Studies. The Foreword is by Frank Drake. This interdisciplinary book will benefit everybody trying to understand whether evolution and ethics are unique to Earth, or whether they are built into the fabric of the universe. (shrink)

How (Not) to Be Secular is what Jamie Smith calls "your hitchhiker's guide to the present" -- it is both a reading guide to Charles Taylor's monumental work A Secular Age and philosophical guidance on how we might learn to live in our times. Taylor's landmark book A Secular Age (2007) provides a monumental, incisive analysis of what it means to live in the post-Christian present -- a pluralist world of competing beliefs and growing unbelief. Jamie Smith's book is a (...) compact field guide to Taylor's insightful study of the secular, making that very significant but daunting work accessible to a wide array of readers. Even more, though, Smith's How (Not) to Be Secular is a practical philosophical guidebook, a kind of how-to manual on how to live in our secular age. It ultimately offers us an adventure in self-understanding and maps out a way to get our bearings in today's secular culture, no matter who "we" are -- whether believers or skeptics, devout or doubting, self-assured or puzzled and confused. This is a book for any thinking person to chew on. (shrink)

Ludwig Wittgenstein (1889-1951) was an extraordinarily original thinker, whose influence on twentieth-century thinking far outside the bounds of philosophy alone. In this engaging Introduction, A.C. Grayling makes Wittgenstein's thought accessible to the general reader by explaining the nature and impact of Wittgenstein's views. He describes both his early and later philosophy, the differences and connections between them, and gives a fresh assessment of Wittgenstein's continuing influence on contemporary thought.

Background: The magnitude of bullying and harassment among psychiatrists is reportedly high, yet no peer-review published studies addressing this issue could be found. Therefore, it was decided to conduct a pilot study to assess the degree of the problem, the types of bullying/harassment and to provide some insights into the situation.Methods and Principal Findings: Following multiple focus group meetings, a yes/no response type questionnaire was developed to assess the degree and type of bullying and harassment experienced by psychiatrists. Over a (...) 3-month period the questionnaire was administered to a random sample of 60 psychiatrists. 57 out of the 60 psychiatrists reported harassment and bullying. Frequencies of the following response variables are presented in descending order: rumours 40% ; defamation 20% ; passing remarks 20% ; false accusations 15% ; threats 13.3% ; verbal abuse 13.3% ; unjustified complaints 13.3% ; promotion blocked 13.3% ; humiliation 13% ; bad reference given 10% ; credentials questioned 8.3% ; physical attacks 5% ; termination 5% ; derogatory remarks 1.7% and 1.7% were subjected to personal work. As a result of being subjected to harassment, 66.7% of the psychiatrists did not take any action, whereas 33.3% confronted the person they believed responsible. Asked whether the bullying and harassment caused distress, 18.3% of the psychiatrists did not report any effect, 30% reported mild distress, 40% moderate distress and severe distress was reported by 11.7%.Conclusions: It was concluded that the magnitude of bullying and harassment among psychiatrists may be quite high, as evidenced by this pilot study. There is a need for extensive systematic studies on this subject and to establish strategies to prevent and address this issue at a national and regulatory level. (shrink)

This introduction to the basic ideas of structural proof theory contains a thorough discussion and comparison of various types of formalization of first-order logic. Examples are given of several areas of application, namely: the metamathematics of pure first-order logic (intuitionistic as well as classical); the theory of logic programming; category theory; modal logic; linear logic; first-order arithmetic and second-order logic. In each case the aim is to illustrate the methods in relatively simple situations and then apply them elsewhere in much (...) more complex settings. There are numerous exercises throughout the text. In general, the only prerequisite is a standard course in first-order logic, making the book ideal for graduate students and beginning researchers in mathematical logic, theoretical computer science and artificial intelligence. For the new edition, many sections have been rewritten to improve clarity, new sections have been added on cut elimination, and solutions to selected exercises have been included. (shrink)
