Le rire et le théâtre dans la Lettre à M. d’Alembert

Often interpreted as a field of contradictions and fragmentation, the work of Jean-Jacques Rousseau presents an inner unity. This inner unity, though, is structured around regulated contradictions. I will examine here the distribution of those regulated contradictions by focusing on the preface to the Lettre à M. d’Alembert sur les spectacles and the relations between the Lettre and the Essai sur l’origine des langues. What Rousseau rejects as agents of corruption—theater and laughter—constitute at the same time the principles of his argument. The values of representation and technique implied by theater and laughter come to compose with those of presence and nature. Taking as a point of departure the work of Jacques Derrida on Rousseau, but also engaging it polemically, I will show in the analysis of the preface to the Lettre the distribution of regulated contradictions as well as the essential difference between language and theater in Rousseau throughout his reflection on the origin of theater and language.     

Les « Causes Secrètes » Causalité et Déterminisme à L’âge Classique

The notion of the “secret cause”, which appears in many classical texts is tied to a particular practice of science and a conception of its methods where the “law” finds itself at the center of the nexus. If certain phenomena appear to escape the law, one is obliged to amend the law through the introduction of a series of “small equations.” If the calculation of probabilities is deployed, this is to precisely reveal causes which are, at their origin, secret, but which will gradually become less so and eventually conform to laws.     

Histoire des idées, sociologie des croyances et processus argumentatifs scepticisme et modernité d’après Richard H. Popkin

This paper claims to show the relevance of the classical book by Richard H. Popkin from the point of view of a sociological and anthropological analysis of the collective processes of doubt and assent. This examination implies, however, that we analyse the fine differences between the history of ideas, the sociology of knowledge, the ethnology of beliefs and epistemology. The examination deserves to be carried out as well for the understanding of the increase of scepticism in the 17th century as for the spread of the wave of contemporary relativism. The latter certainly has to be distinguished, as Popkin suggests, from a form of moderate scepticism close to critical rationalism.     

Trois revues institutionnelles : Le Journal de l’École polytechnique,les Annales des Mines,les Annales des Ponts et Chaussées

The three journals studied are characterized by their own institutional background, which explains most probably their centenial longevity, and their slow evolution. The Journal de l’École polytechnique is more academic. The two Annales publish scientific, technical and legislative texts. They are a bond between the administration and its engineers. As the bulk of published articles is huge and diversified, it was important to develop an effective system of access to the various articles.
