On the basis of the trajectory of something made of paster which had impassioned the statisticians of the years 1880 and which furnished André Breton the very exemple for the notion of a surrealist object, one wonders whether the surrealist theory of chance was born by chance. By translating the issue which Ernest Coumet addressed in 1970 concerning the Pascalian geometry of chance, we investigate here the relationship between the history of science, art history and the history of scientific culture during the last century. In return, we hope to suggest why Coumet's article opened such a wide horizon in the history of the theory of probabilities thirty years ago.  相似文献

Cet article présente les caractéristiques et l'évolution de la propriété foncière, du marché foncier et des systèmes de production agricoles en Lombardie orientale au 19e siècle. L'auteur analyse les impacts sur l'exploitation de la terre de la substitution des propriétaires fonciers nobles par des bourgeois; des maladies du ver à soie et des vignobles, de l'arrivée des grains américains moins chers; de l'utilisation d'engrais chimiques et d'équipements modernes. Il montre que si la petite propriété représente toujours près d'un tiers du total et que la magnanerie et la viticulture diminuent, il est relevé une croissance des cultures céréalières et fourragères et des dépenses consacrées aux innovations technologiques. Il signale la rationalisation des cultures, l'amélioration des rendements et de la qualité des récoltes ainsi que des revenus non déclarés pour éviter les impôts et explique pourquoi les investisseurs préfèrent les petits aratori comportant des mûriers et des vignobles. Enfin, il donne à voir que l'organisation des exploitations reste liée au degré de risque pris par le propriétaire (la rente fixe garantie par le bail à ferme payé en argent ou une gestion directe de la propriété) et aux cultures (la présence des vignobles et de la magnanerie favorisant les sharecropping contracts).  相似文献

At least from the standpoint of the steam‐engine industry, the nature of industrial relations between France and other countries underwent a significant change during the half century which elapsed between 1860 and 1910. Towards 1860, the major characteristics are dispersion and nationalism; on the other hand, at the beginning of the twentieth century, while there is a new concentration on the national level, it confronts a distinct cosmopolitanism on the international level. To give an idea of this evolution, we will refer to two French works on steam‐engines, dated 1861–62 and 1913 respectively. They are of an essential practical nature and describe a large number of engines which were actually available on the market. Below, we will successively examine the early manufacturers existing through 1861–62, then those dating from 1913 only, and finally the establishments which have endured throughout the whole period under consideration. This study aims at pointing out the clear decadence of the French industry which became increasingly dependent upon foreign sources in the areas of technical creativeness as well as production.  相似文献

Early modern radicalism and its criteria are described and defined by Jonathan Israel in various works. Poulain de la Barre, one of the first modern feminist thinkers, first is used by Israel as an example of the so-called radical Enlightenment and finally is rejected as such. This case study exhibed the necessity of questionning the coherence of the required criteria for defining a « radical » thinker, especially when examinating carefully the last paragraph of Spinoza’s Political Treatise.  相似文献
