Ordre des décrets divins,hiérarchie des droits humains

Until the xvi^th century, the use of public force in the service of religious unity seems to be a consequence of a zeal for the salvation of others. In order to reach civil peace, in the nations where different creeds confronted each other, it was necessary to find a theological foundation for the legal recognition of a freedom of conscience and of religion. The Protestant theologians of the Academy of Saumur, founded by Philippe Duplessis-Mornay, a negotiator of the Edict of Nantes, sought this foundation in a theology of creation. God created man to live peacefully in the company of his fellow-men and the drama of original sin, although it led for its reparation to a revelation from God, protected by the Church, did not destroy this primary order. «We are men, writes Amyraut, before being Christians.»     

Le jugement des fléches

Diagrams, schemata, itineraries, we are accustomed to forms of arrowheads in representation. These forms often evoke movements that writing necessarily freezes on the paper while they propose to themselves to express their dynamics. Recent progress in techniques of communication and of expression permit us at times to surmount these difficulties. When they can spread out into space (and time) of a prop able to entrer in its turn into movement (a machine — or simply a hand), this “liberated” forms permit us to remove (or at the every least to rattle) important epistemological obstacles which subsist in practice as in theory.     

L'arrivée des premiers métallurgistes sur l'Ogooué, Gabon

Résumé Au Gabonca 2400–2300 BP, les dernières cultures néolithiques des savanes de la moyenne vallée de l'Ogooué, succombent face à une rapide expansion de populations porteuses de fer. Cet événement, identifié sur des critères céramologiques et des mesures radiométriques, paraît situer l'arrivée des premiers métallurgistes — probablement Bantu — sur les berges de l'Ogooué.

In the savannas of the middle stretches of the Ogooué valley in Gabon,ca 2400–2300 bp, the last neolithic cultures succombed to the rapid expansion of ironworking populations. This event, identified on ceramic criteria and radiocarbon dates, may represent the arrival of the first Bantu ironworkers on the banks of the Ogooué.

     

Diversité des réactions réformées à la révocation

Starting from the analysis of the reactions of the Protestant groups to the Fontainebleau edict, this paper examines the development of two main concepts that are at the origin of political modernity, i.e. the distinction between religious and political domains on the one hand, and the popular sovereignty on the other. These two concepts emerged separately as a result of crossed and apparently paradoxal thoughts, whose coherence is to be sought in the anthropological positions underlying them. Therefore the study of the theological debates in the XVII^th century is a way by which the modern political concepts arose.     

L’histoire des mathématiques de l’Antiquité

Historical research, during the last half-century, has improved our knowledge of the mathematics of Antiquity. Texts from Egypt and Mesopotamia have been better understood and their elucidation has left behind the crude alternative between empricism and rationalism. The landscape offered by Greek science grew richer and became more varied: it is no longer possible to reduce it to the sole geometrical theory. The main problems which were raised by its history have been deeply discussed. Things being so, more general questions arise, from an epistemological or philosophical point of view. Does the search into some far past of a single «birth» of mathematics make any sense? What link, if any, is there between the form of mathematics in such and such a civilization and its social structure? Can cultural anthropology help to elucidate the variety and unity of mathematics among various peoples? From what time and under what conditions is it possible for a single united historical progress of mathematics to begin?     

Rex imago dei: Charles V of France and the Livre des propriétés des choses

The subject of this paper is the Livre des propriétés des choses, the fourteenth-century French translation of the thirteenth-century encyclopedia De proprietatibus rerum. The translation was made for Charles V of France, and the original copy is lost. Here a reconstruction is offered of the appearance of the frontispiece of the royal exemplar. The textual additions of the translator and the iconography of this frontispiece reveal a new conception of the meaning and usage of the encyclopedia, as well as a concerted attempt to draw this authoritative work into the orbit of royal aims and aspirations. The reconstructed frontispiece also allows us to correct an error, which originates with Montfaucon, concerning the illustration of the original copy of the Livre des propriétés des choses.     

Quelques repéres historiques sur la théorie des jeux

Résumé  L'article s'attache à dégager le fil rouge qui relie les réflexions de Wilhelm Gottfried Leibniz sur les jeux de société à la théorie des jeux, telle qu'on la trouve dans l'ouvrage de John Von Neumann et Oskar Morgenstern. L'itinéraire décrit passe par les travaux de plusieurs mathématiciens du XVIII^e siècle sur différents jeux de hasard, pour aboutir aux recherches de quelques-uns des fondateurs des mathématiques modernes, comme Ernst Zermelo pour la théorie des ensembles et émile Borel pour la théorie des probabilités. II montre comment une analyse mathématique des jeux de société a débouché sur l'élaboration d'une grille générale d'analyse des phénomènes sociaux. Son cheminement révèle, en outre, la longue parenthèse du XIX^e siècle où ce programme s'est trouvé abandonné et esquisse, en conclusion, quelques hypothèses pour l'expliquer. The paper strives to find the clue which links Leibniz' thoughts on parlour games to the mathematical theory of games in John Von Neumann and Oskar Morgenstern.Magna opera the way goes through the works of several XVIII^th century mathematicians on various games of chance to reach the research of some of the modern mathematics founders, as Ernst Zermelo for the sets theory and émile Borel for the theory of probabilities. The paper shows how a mathematical analysis of parlour games ends at a general framework to study the social phenomena. Its development also reveals how this research program has disappeared, all along the XIX^th century, and suggests, in conclusion, some tentative explanations of this development. Une version préliminaire de cet article a été publiée dans la revue de l'Association historique des élèves du lycée Henri IV,Jeu et histoire, n^o spéc.:L'émoi de l'histoire, 25–26, printempsautomne 2002, p. 94–115.     

La révolution scientifique les révolutions et l'histoire des sciences

In the paper Ernest Coumet presented at the conference on Koyré (Paris, 1986), he suggested that the term «scientific revolution» does not denote for Koyré an historical event, but an idealtype, in Weber's sense. First, the author discusses this thesis and presents the arguments Coumet advances to support it. In the second part of his paper, he criticises the use of the notion of revolution in the history of science. In particular, he argues against the distinction between scientific theories and a «scientific thinking», which would be influencedby the «philosophical thinking» and whose changes would produce a revolution.
