" Si René Guénon apparaît bien, au XXe siècle, comme l'incontestable représentant du renouvellement de la " Connaissance Sacrée ", il est cependant un domaine, paradoxalement, encore relativement peu exploré dans le cadre des études portant sur son œuvre et qui pourtant est essentiel, et où son autorité, nous semble-t-il, s'impose de façon majeure, c'est celui de la Métaphysique. La Métaphysique de René Guénon fait suite au Dictionnaire de René Guénon, et à ce titre doit être regardé comme son complément (...) théorique naturel, permettant d'offrir aux lecteurs de l'œuvre de Guénon un éclairage approfondi portant sur les bases essentielles de la doctrine éternelle à laquelle il consacra toute sa vie. Cette doctrine, se perdant dans la nuit des temps, est attachée à la " Tradition primordiale " d'une manière extrêmement intime, à ce point tel d'ailleurs que l'on peut dire qu'elle en est sa substance la plus intérieure.

This paper proposes a synthetic presentation of the proof construction paradigm, which underlies most of the research and development in the so-called “logic programming” area. Two essential aspects of this paradigm are discussed here: true non-determinism and partial information. A new formulation of Focussing, the basic property used to deal with non-determinism in proof construction, is presented. This formulation is then used to introduce a general constraint-based technique capable of dealing with partial information in proof construction. One of the baselines (...) of the paper is to avoid to rely on syntax to describe the key mechanisms of the paradigm. In fact, the bipolar decomposition of formulas captures their main structure, which can then be directly mapped into a sequent system that uses only atoms. This system thus completely “dissolves” the syntax of the formulas and retains only their behavioural content as far as proof construction is concerned. One step further is taken with the so-called “abstract” proofs, which dissolves in a similar way the specific tree-like syntax of the proofs themselves and retains only what is relevant to proof construction.

Jean-Marc Moschetta | Résumé : Phénoménologie de la transcendance, publié par Sophie Nordmann, propose une réflexion sur certains concepts classiques de la théologie : création, rédemption, transcendance, etc. La thèse principale de l’ouvrage est que le monde est insuffisant à rendre compte de lui-même et que cette incomplétude est elle-même indéductible du monde. D’où le caractère authentiquement créé du monde. La création du monde, entendue strictement sur le mode de « l’insuffisance ontologique à soi », apparaît alors comme (...) un concept délié du don originel et permet de faire l’économie d’un Dieu créateur. Cet article met en regard cette analyse et celle qui est issue de la tradition théologique. En particulier, même si la construction de la thèse principale de l’ouvrage est contestée sur la base des contre-exemples fournis par les sciences contemporaines de la nature, la conclusion de l’ouvrage qui proclame le lien entre création et rédemption d’un monde en voie d’achèvement peut être reçue comme une confirmation de la légitimité de la théologie naturelle contemporaine. |: Phénoménologie de la transcendance, published by Sophie Nordmann, offers a philosophical thought on some classical concepts of theology such as : creation, redemption, transcendence, etc. The main thesis of the book is that the world is insufficient to account for itself. Moreover, the world incompleteness cannot be inferred from the world. Hence the world as a genuine created entity. The creation of the world, strictly understood as the “ontological self-insufficiency” appears as a concept independent of the original gift and allows to consider God the Creator as unnecessary. The present article compares Ms. Nordmann’s analysis with the one inherited from the theological tradition. The main book thesis is disputed on the basis of counter-examples issued from contemporary natural sciences. Yet, the conclusion proclaims a connection between creation and redemption of a world in the process of accomplishment. That conclusion may be regarded as confirming the legitimacy of contemporary natural theology. (shrink)

Jean-Marc Coicaud's article begins by stressing the contemporary importance and the current trend of political apology. Recent political apologies offered in Australia and Canada to their indigenous populations form a significant part of this story. He then analyzes a number of intriguing paradoxes at the core of the dynamics of apology. These paradoxes give meaning to apology but also make the very idea of apology extremely challenging. They have to do with the relationships of apology with time, law (...) and the unforgivable. The most intriguing of these paradoxes concerns apology and the unforgivable. Indeed, the greater the wrong, the more valuable the apology. But, then, the more difficult it becomes to issue and to accept an apology. This latter paradox is namely examined in the context of mass crimes, taken from Europe, Africa and Asia. As a whole these paradoxes are all the more intriguing considering what apology in a political context aims to accomplish, for the actor who issues the apology, for the one who receives it, for their relationship, and for the social environment in which this takes place. Jean-Marc Coicaud concludes his article by outlining what the rise of apology means for contemporary political culture. (shrink)

We address the issue of belief revision in a multi-agent setting. We represent agents' beliefs in a semantic manner, through a Kripke structure, and model a communication process by which agents communicate their beliefs to one another. We define a revision rule that can be applied even when agents have contradictory beliefs. We study its properties and show that agents need not agree after communicating their beliefs. We finally address the dynamics of revision and show that the order of communication (...) may affect the resulting belief structure. (shrink)

Parkinson's disease (PD) is generally sporadic but a number of genetic diseases have parkinsonism as a clinical feature. Two dominant genes, α‐synuclein (SNCA) and leucine‐rich repeat kinase 2 (LRRK2), are important for understanding inherited and sporadic PD. SNCA is a major component of pathologic inclusions termed Lewy bodies found in PD. LRRK2 is found in a significant proportion of PD cases. These two proteins may be linked as most LRRK2 PD cases have SNCA‐positive Lewy bodies. Mutations in both proteins are (...) associated with toxic effects in model systems although mechanisms are unclear. LRRK2 is an intracellular signaling protein possessing both GTPase and kinase activities that may contribute to pathogenicity. A third protein, tau, is implicated as a risk factor for PD. We discuss the potential relationship between these genes and suggest a model for PD pathogenesis where LRRK2 is upstream of pathogenic effects through SNCA, tau, or both proteins. (shrink)

L'analyse des mythes peut prendre une portée métaphysique plus que socio- ou psycho-historique. L'on peut s'attacher ainsi à la figure du héros qui la caractérise le mieux en essayant de la sauver des dépréciations qu'elle n'a cessé de subir. C'est en effet une esthétique du juste qu'elle traduit, à travers les exemples constants de la création culturelle et surtout littéraire et épique. Cette esthétique n'est pas subjectiviste, ni formaliste, ni génériciste, mais plutôt objectiviste, réaliste et universaliste , elle est une (...) esthétique du contenu et de l'objet, du sentiment et de l'idée de la justice. Il en ressort un primat de l'existant singulier humain souvent saisi dans la précarité tragique de sa condition et dont la justice, ayant vocation à devenir droit et loi, exige qu'il soit protégé en la totalité corporelle et morale de son sens.

The hypothesis that the particular linear tracks appearing in the measurement of a spherically-emitting radioactive source in a cloud chamber are determined by the positions of atoms or molecules inside the chamber is further explored in the framework of a recently established one-dimensional model. In this model, meshes of localized spins 1/2 play the role of the cloud-chamber atoms and the spherical wave is replaced by a linear superposition of two wave packets moving from the origin to the left and (...) to the right, evolving deterministically according to the Schrödinger equation. We first revisit these results using a time-dependent approach, where the wave packets impinge on a symmetric two-sided detector. We discuss the evolution of the wave function in the configuration space and stress the interest of a non-symmetric detector in a quantum-measurement perspective. Next we use a time-independent approach to study the scattering of a plane wave on a single-sided detector. Preliminary results are obtained, analytically for the single-spin case and numerically for up to 8 spins. They show that the spin-excitation probabilities are sometimes very sensitive to the parameters of the model, which corroborates the idea that the measurement result could be determined by the atom positions. The possible origin of decoherence and entropy increase in future models is finally discussed. (shrink)

English summary: Neoplatonism leads to the difficulty of explaining what is nature beyond being or essence. But what does being beyond the being mean? And if the One is above being, what can he be, if not nothing? The erudite discussions explored by Jean-Marc Narbonne lead readers along paths of ontology and henology, through our speculative tradition, from Aristotle, Plato, and Plotinus to Heidedegger. French description: Quiconque s'est expose a la pensee neoplatonicienne, ete confronte a la difficulte d'expliquer (...) en quoi consiste la nature au-dela de l'etre ou de l'essence - selon la formule platonicienne -, du Premier principe des Neoplatoniciens. Que peut bien signifier etre au-dela de l'etre? Est-ce que n'est pas dit etre tout ce qui existe, et si l'Un est au-dela de l'etre, que peut-il justement etre, si ce n'est le rien, le neant? Et s'il n'est pas pur neant, c'est donc que, d'une certaine maniere, il est. Des lors, pourquoi ne pas l'admettre plutot que d'emprunter ce curieux et apparemment inutile detour par l'Un, par l' henologie? Ces interrogations sont centrales, puisque d'elles depend l'intelligence de ce qui constitue l'essentiel de notre tradition speculative, les courants ontologique et henologique, respectivement rattaches aux noms d'Aristote et de Platon/Plotin, formant l'armature meme de notre heritage conceptuel. Et l'oubli meme de l'etre decrie par Heidegger, dans tout cela? Peut-il avoir le meme sens dans une philosophie de l'etre et dans une philosophie qui, expressement, methodiquement, choisit de se situer dans une perspective autre que celle de l'etre, etre que par la justement, elle n'oublie pas, mais qu'intentionnellement elle delaisse et maintient a distance? Jean-Marc Narbonne est professeur de Philosophie ancienne a l'Universite Laval (Quebec) et s'interesse a la tradition platonicienne et a son influence dans l'histoire occidentale et dans la pensee contemporaine.

Between 1962 and 1967/68, Ricœur devoted several courses to the question of language. Even though there are many traces of these lectures in the articles and essays published during these years, they have so far attracted little attention from the research community. However, they mark a decisive turning point in Ricœur’s thinking and lay the systematic foundation of the hermeneutics of the text that he would deploy in his later works. The article first clarifies the place occupied by these courses (...) in Ricœur’s work. It then presents the archival material and characterizes the specific approach of each of the courses on the basis of Ricœur’s preparatory manuscripts. In a final section, three particularly instructive aspects of the courses are discussed: the shift from symbol to metaphor, the articulation of analytic philosophy and phenomenology, and finally the program of a transcendental foundation of the rules of discourse production.

The article proposes a systematic reconstruction of Joas’ theory of the sacred. After having characterized the disciplinary profile of Joas, who is a specialist in social theory and historical sociology, and presenting his approach, which ties together pragmatism and hermeneutics, it will be seen how Joas’ theory of the sacred is rooted in his theory of the genesis of values. For Joas, this genesis is closely tied up with the experiences of self-formation and self-transcendence, which can be collective (Durkheim) as (...) well as individual (James). Joas qualifies them as experiences of the sacred, which are susceptible to religious articulation. Therefore, religion is a possibility for interpreting the sacred. This mode, however, may itself assume a variety of forms, not necessarily making recourse to the category of the transcendental, which represents the major discovery of what Karl Jaspers named the axial age – a central topic of Joas’ work for about 15 years. As an alternative to the Weberian notion of disenchantment, Joas develops his history of sacralization and desacralization on this ground. (shrink)

The objective of this study is to identify and categorize the focus of selective attention and reasoning of students in Secondary teacher education in French-speaking Belgium during the observation of teaching situations on video or in real context. A cross-fertilization between categories from a theoretical framework and another research highlighted some characteristics that students consider relevant during their observation and the type of reasoning they mobilize.

The favourable reception of the analytic philosophy of language plays a central role in the composition of Ricœur’s literary hermeneutics. Following a brief description of the historical and methodological context of this reception, we show how Ricœur intends to link up phenomenology and analytic philosophy of language. Then we examine the role allocated to the analytic philosophy of language in establishing the idea of metaphor as a “more fundamental mode of reference” in The Rule of Metaphor . But once again (...) Ricœur situates this semantic interpretation of metaphor within the context of an ontology. The result is methodological difficulties that mark the limits of Ricœur’s reception of the analytic philosophy of language. Keywords: Semantics, Metaphor, Ontology, Structuralism, Poetics. Résumé La réception de la philosophie analytique du langage joue un rôle central dans la constitution de l’herméneutique littéraire de Ricœur. Après avoir tracé le cadre historique et systématique dans lequel s’inscrit cette réception, on montre comment Ricœur se propose d’articuler phénoménologie et philosophie analytique du langage. On étudie ensuite le rôle assigné à la philosophie analytique du langage pour la mise en place de la conception de la métaphore comme “mode plus fondamental de la référence” dans La métaphore vive . Mais Ricœur situe encore une fois cette interprétation sémantique de la métaphore dans un cadre ontologique. Il en résulte des difficultés systématiques qui marquent les limites de la réception de la philosophie analytique du langage par Ricœur. Mots-clés: Sémantique, Métaphore, Ontologie, Structuralisme, Poétique. (shrink)

The article focuses on how emotions and passions are addressed in the field of international relations. As such it makes three main points. First, the article argues that, although presupposed in mainstream international relations, because of the influence of positivism emotions and passions have tended to be overlooked. Second, it makes the point that in recent years scholars with constructivist leanings have been increasingly interested in taking emotions and passions seriously as an academic area of research. Third, and finally, the (...) article concludes that despite the progress made in the 2000s on the understanding of emotions and passions in international relations, more work remains to be done. As such it outlines future directions of research. (shrink)

This book reveals the French scientific contribution to the mathematical theory of nonlinear oscillations and its development. The work offers a critical examination of sources with a focus on the twentieth century, especially the period between the wars. Readers will see that, contrary to what is often written, France's role has been significant. Important contributions were made through both the work of French scholars from within diverse disciplines, and through the geographical crossroads that France provided to scientific communication at the (...) time. This study includes an examination of the period before the First World War which is vital to understanding the work of the later period. By examining literature sources such as periodicals on the topic of electricity from that era, the author has unearthed a very important text by Henri Poincaré, dating from 1908. In this work Poincaré applied the concept of limit cycle to study the stability of the oscillations of a device for radio engineering. The “discovery” of this text means that the classical perspective of the historiography of this mathematical theory must be modified. Credit was hitherto attributed to the Russian mathematician Andronov, from correspondence dating to 1929. In the newly discovered Poincaré text there appears to be a strong interaction between science and technology or, more precisely, between mathematical analysis and radio engineering. This feature is one of the main components of the process of developing the theory of nonlinear oscillations. Indeed it is a feature of many of the texts referred to in these chapters, as they trace the significant developments to which France contributed. Scholars in the fields of the history of mathematics and the history of science, and anyone with an interest in the philosophical underpinnings of science will find this a particularly engaging account of scientific discovery and scholarly communication from an era full of exciting developments.

Finally, two acts of 1430 on Buondelmonti, dean of (...) this chapter, are presented here. (shrink)

Dès 1678, Leibniz, dans plusieurs manuscrits, propose la fondation d’une caisse d’assurance. Il évoque également un fonds de réserve et un mont-de-piété. Selon une approche à la fois théorique et pratique, le philosophe pose et explicite les deux principes fondateurs de l’assurance : précaution et équité. Il recommande par ailleurs la constitution de rentes viagères. Afin de déterminer leur taux, il approfondit la notion d’espérance de vie, elle-même dépendante d’une estimation des probabilités ou risques de décéder. Leibniz conçoit l’ordre de (...) la mortalité comme un processus aléatoire. Il fournit des indications qualitatives et quantitatives sur le risque de décéder pour des grands groupes d’âge, puis entreprend, au moyen d’un modèle simplificateur, de trouver une durée probable de la vie humaine. En présentant le processus d’extinction d’une population comme une combinatoire de risques, ces recherches donnent l’occasion d’établir un dialogue entre le certain et le possible, entre la nécessité et la contingence.
