Communautés de Savoirs

The social and institutional history of the university of Paris still frequently remains detached from the study of the intellectual dynamics which were produced in its midst. The concept of «communities of knowledge » allows us to fill this gap by narrowly associating the history of knowledge to its concrete conditions of production and teaching. This model permits us to give attention to the maintenance, in the midst of the Parisian university of diverse «schools » endowed with orientations and specific programmes of research. The appearance of colleges can equally be situated in this perspective, which permits us to better grasp the interaction between the political and intellectual stakes which lay stress on the history of the university in the xiii ^th century. Finally, it neveals the image of an institution more fragmented than unified.     

Bons Procédés Entre Érudits

This article exposes certain functions of scientific correspondence during the second half of the 16(th) century. A professor of mathematics in Rome, Antonio Maria Pazzi, sends a mesolabe together with a letter to Barbaro, the humanist scholar of Venice. The latter would include parts of it in the Latin version of his commentary to Vitruvius. The analysis of the context of this publication shows that both arrive at aligning their personal intentions with the ideal of the "common good" by contributing to the spread of mathematical knowledge and practices.     

Lacan et les probabilités

Lacan was interested by the treatment of the probabilities, the theory of games and decision, all topics that gave way to an interpretation of Pascal’s calculus of partition and of the famous argument of betting. Starting from a critical examination of Kant’s transcendental aesthetics, that Lacan propounds to the philosophers to replace by logical space and time of the theory of game (as a substitute), the psychoanalyst attempts to prove that Pascal is probably the forefather of the theory of game and decision. A number of interpretations of the «geometer of hazard», which will happen in the years 1970, are in debt, perhaps unconsciously, surely in a secrete way, to the farther lacanian interpretation.     

Induction, probabilités et confirmation chez Carnap

The idea of associating probability and induction is not a theme suitable for the xx^th century but it has received a systematic development when the neo-positivist philosophers seized it. Beginning with the 1940's, the philosopher Rudolph Carnap proposed to affront the «Humian challenge» by founding a theory of confirmation through the construction of a probabilistic logic called «inductive». This project had been outlined in Cambridge during the 1920's by the economist John M. Keynes. To examine Carnap's program in its totality, to situate it in its historical context, to follow its evolution and the influences it has had, these are the aims of this article.     

Voyages,mobilités,lumières

For a very long time and still today, travel stories have fascinated a vast public. It is important to debate their role and the model for intellectual and sensitive construction they propose. An essential link for the European elite's acculturation, they cannot for as much be separated from a much wider circulation which concerns society as a whole. In relation to the social morals of our past, the concept of mobility allows us to appreciate the totality of social practices and to confront the notions of movement and localization. The main cultural categories of space, time, sociability, social constraints and freedoms, are thus creating a structure for our understanding of change.     

El pulso de Centro América a través de la novela

This article offers a new reading of Miguel de Unamuno's San Manuel Bueno, mártir. Critics have traditionally focused on the question of the protagonist's supposed lack of faith and sought to relate San Manuel's doubts in the novel to Unamuno's own religious views. Although this novel is very much concerned with religion, eschatology, and social issues, it is also an extremely sophisticated literary narration wherein the use of irony and ambiguity remains perhaps unequalled in Spanish contemporary literature. By considering the principles of linguistic pragmatics, this article shows that in her account of San Manuel's life, the female narrator tells the dramatic story of the love she and San Manuel felt for each other. By means of a complex use of ambiguity, Unamuno writes a novel that can be read in two different ways: the religious novel and the love novel.     

Relativités et puissances spectrales chez Gaston Bachelard

La Valeur inductive de la relativité is undoubtedly the least known «philosophical» work of Gaston Bachelard. Before an almost total silence, with the absence of readings, the replies are only «first type» interpretations supported by a certain discursive hearsay, but which have the authority of pseudo-standards. The Bachelardian positions are here confronted byLa Déduction relativiste of Émile Meyerson. The weight of the analysis will essentially rest upon a display of the Bachelardian device ofinduction and ofconstruction. The «inductive» preparation must be thought out on the electromagnetic model and the «constructivist» position is always linked to the effort of synthesis. In short, it is a veritablemeta-physics which seemingly must generate this «thought of the sciences».     

Sur l'expertise anthropologique territoires et identités indigènes au Brésil

Is it possible for an anthropologist to decide whether an individual or a collectivity can or cannot be characterized as « indigenous », and then proceed to establish the limits of the territory which should be assigned (or recognized) by the state? Does his role as a scientist furnish him with the conceptual and methodological instruments necessary for such a task? In epistemological and ethical terms, is this something which he should endeavour to do? The purpose of this paper is to discuss how these questions are being put to Brazilian anthropologists since the 1980s. Torn between an « indianist » and an « indigenist » discourse, between romanticism and political mediation, the anthropologist must define an appropriate posture for dealing with policy-making; one which will simultaneously safeguard the scientific quality of his work while addressing the specific demands of each situation.
