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.     

La réflexion Benthamienne sur les mathématiques

In 1814, Jeremy Bentham began to writeChrestomathia; this work is a presentation of what is useful to learn. However this text is, more generally, an entire organization of the knowledge of his time, through developing a «theory of fictions», which is a reflexion on concepts and a critics of nomenclatures. The following essay focuses on the fifty pages refering to mathematics in a work that considers the integrality of sciences at the beginning of the xix^th century and criticizes the FrenchEncyclopédie of Diderot and D’Alembert. A most singular idea expressed by the author, indirectly echoed by Gaston Bachelard through some books, is the conflict between concepts and their being designated by words. Signified, signifying entities and concepts are reciprocally adrift so that nobody, even the scholar, can keep control of these motions; what makes education unceasingly difficult.     

Comment nommer les éléments? les catégories anthropologiques en afrique du sud

South African anthropology has been historically divided into two schools. One, associated with the Afrikaans-language universities, was favourable toapartheid. The other, associated with the English-language universities, was opposed to segregation and racial discrimination. Afrikaner anthropology focused on culture, tradition, and ethnicity, while the other school was committed to the study of South Africa as a single, rapidly changing society. This opposition has sometimes been exaggerated, and it was most significant during the period of highapartheid in the sixties and seventies but there has always been considerable debate over the very objects of anthropological research, and in particular about the nature of the «racial» and «tribal» groups in South Africa. These issues were politically of the greatest significance, forcing anthropologists to confront great questions about government policy. This paper traces the history of these debates on the classification of the peoples of Southern Africa.     

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.     

Tenue de soirée de rigueur: Incursion chez les warocqué

The Warocqué family, “nouveaux bourgeois”, were characterised by their constant intention to change the world in which they lived. They were thus industrialists and businessmen and political representatives as was appropriate, but also inventors, paternalist, philanthropists and employers. The Warocqués thus present a multitude of facets and possibilities for study. It was necessary to give greater importance to one of them, particularly as everything could be encompassed as family business. It is precisely the evolution and progression of the family in its local, Belgian and even international contexts that is analysed here—family, tradition and dynasty even: inaugurated by Nicolas, it progresses, develops and reaches its apogee with Raoul, who benefited from the power of the name. This social rise was also interpreted on the level of traditions, of family, of prestige or of a way of life. The article aims to study this particular aspect while successively reviewing some ‘chapters’ in the life of this dynasty: the family (taken as it should be in the broad sense, joining the very current concept of ‘network’), its sociability and passions.     

Épistémologie, histoire et histoire des sciences dans les années 1930

During the 1930’s epistemology, history and history of science reciprocally and importantly influenced each other, even if indirectly. Philosophers and historians discussed the epistemological concepts emerging from the crisis of the exact sciences. They rejected Empirism and Idealism for an «experimental Rationalism» that connected theory and experience. It all caused a dialectical conception of science, fundamentally historical, but for which historians were still reluctant from a theoretical point of view. History was nevertheless the centre of philosophical and epistemological reflexions.     

Wu Youxing 吳有性 et les Épidémies Pestilentielles

Faced with the terrible mortality of the epidem ics during the last years of the Ming Dynasty (1368–1644) and the inefficacy of the treatm ents applied, Wu Youxing (ca 1580–1660), the author of the Wenyilun 温疫論 (Treatise on warmfactor epidemics), completed in 1642, proposed a new etiological explanation of these diseases, with a highly critical attitude towards his predecessors. Reception to the book was mixed; it sometimes encountered opposition due to the audacity of some of Wu Youxing’s conceptions, but also, most likely, to the discrepancy between the author’s assertions and the failures in actual application.     

Sur les traces de Cortés: L'expédition du Mexique d'après Le Monde illustré

Unlike L'Illustration, with which it competed under the Second Empire, the weekly Le Monde illustré, which first appeared in 1857 and which was protected by the imperial government, did not count among the political newspapers overtaxed under Napoléon the Third's repressive regime. For this reason, it made great strides thanks to its blind allegiance to a French imperialism that had asserted its authority during the Crimean war, but which spent itself during the war against Juárez and his republican partisans in Mexico. While the French liberal press criticized the Second Empire foreign policy, Le Monde illustré persisted in turning the Mexican war into an antijuarist pacification favorable to a new Latin colonial empire, as well as to an application of the Saint-Simonian doctrine on Mexican industry and economy. In order to achieve this, the illustrated reports on the expeditionary force, military operations, and French victories were a warmongering that aimed to place this campaign in the afterglow of the conquistadors' era, as well as to idealize the imperial army as a symbol of the French nation.     

Les échelles de temps sur les marchés financiers

Modern financial modelling massively implements scaling laws to describe market fluctuations, with the use of stochastic processes in stock market price behavior equations. Scaling laws, which already existed as an implicit part of Brownian motion although notperceived at such, habe become increasingly and explicitely important, since the financial markets regulatory authorities have drawn the attention of the banking industry to the risk control issued posed by the ineffective current valuation achieved using the classical Gaussian distribution. The différent elements surrounding this debate are developed based around Mandelbrot's fractal models, which have underlined the main modelling conflicts of the behavior of stock market prices over the last forty years. I demonstrate that the root of the problem of whether scaling laws exist is the more fundemental issue of the nature of market time.     

Les «yeux d’Argos» et les «étoiles d’Astrée» pour mesurer l’univers les jésuites italiens et la science nouvelle

As what happened for thenova in 1604 and for the three comets which appeared in 1618 starting the debate between Galileo and the Jesuits of the Roman College, even the comet of 1644 enhanced the curiosity and expectations in astrometers’ and astrologers’ minds. This work focuses on some aspects of the European debate, by fixing our attention on the Bolognese observatory school of Santa-Lucia in particular, where Giovan Battista Riccioli and his socios had started an experimental activity which was known and appreciated for its accuracy all over Europe. It also closely examines the revaluation of the «medium sciences», such as geography and hydrometry, to point out the sociocultural conditions that originated the growth of new professional characters like engineers and technicians in Bologna.     

Bruit aérien et équité environnementale dans les quatre plus grandes métropoles canadiennes

Previous environmental equity studies have examined the spatial distribution of aircraft noise across cities. Their findings show that, in several cities, visible minorities and low-income populations are most affected by aircraft noise. In contrast, one study concludes that well-off populations are the most affected. These contradictory findings support the use of a comparative approach for several cities. The aim of this study is twofold. First, we want to identify if there are groups in the population that are in a situation of inequity to aircraft noise exposure in Toronto, Montréal, Vancouver, and Calgary. Then, we want to check if the exposure to the aircraft noise of the different groups varies significantly from one metropolis to another. We use the recommended noise exposure contour maps in Canada: the Noise Exposure Forecasts. Next, four variables are extracted from the 2016 Statistics Canada census at a fine-scale level (dissemination areas): that is, the percentages of low-income, visible minorities, 0- to 15-year-old, and 65-year-old and over populations. The results of a mixed effects logistic regression model show that environmental inequities in terms of exposure to aircraft noise for the four population groups are not consistent from city to city.     

Affamer les prisonniers de guerre: entre mythes et réalités, 1914–54

Since the end of the nineteenth century, prisoners of war must be taken in care by their guardians, in terms of food. Sometimes this food is not good enough and leads to cases of starvation. Considering ideological conditions as well as material and chronological evolutions, this paper tries to explain how the prisoners are very often hostages in hands of their guards and how starvation can be an ideological tool.
