Narrativisme et philosophie spéculative de l’histoire

Over the last few decades, such important philosophers as Walter B. Gallie, Arthur Danto, Louis Mink, Hayden White and Paul Ric?ur have drawn attention to the role of narrative in history. After evoking the theses of these authors, this paper pays special attention to the works of David Carr which contend that historical action as such has a narrative structure. The paper discusses the consequences of such a «narrativism» and takes sides in the debate on this question which has been waged in part by William Dray and Noël Carroll. It is claimed that a «realistic» thesis on these matters might tend to generate the revival of a kind of speculative philosophy of history, which naturally would raise various questions concerning both political and historical analysis.     

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?

Les «Faits scientifiques» et leur public: l’histoire de la détection de la syphilis

In the 1910's and 1920', thanks to the conjunction of scientific views concerning the specificity of anti-bacterial antibodies, of lay ideas about the existence of anti-bacterial antibodies and of the perceived importance of developing a syphilis test for public health officials, the community of serologists collectively transformed a relatively inefficient diagnostic test described by Wassermann in 1906 into an "incontestable scientific fact". This "scientific fact" established the equivalence: Wassermann positive individual=person infected with the germ Treponema pallidum, the etiological agent of syphilis. It modified the boundaries of the nosologic entity "syphilis", medical practices, professional attitudes, lay perceptions of syphilis, and health policies. In the 1950's, however, discrepancies between Wassermann test data and epidemiological data and, on the other hand, the development of specific anti-treponemal tests, destabilized the previously stabilized "scientific fact". A high percentage of Wassermann positive individuals were redefined as "biological false positifs", that is persons who suffered from chronic affections able to induce positive results of the Wassermann test. The equivalence Wassermann positive person=individual infected by Treponema pallidum was replaced by the equation: Wassermann positive person=individual infected by Treponema pallidum or biological false positive. The new perception of the Wassermann test again changed scientific views, professional practices and lay beliefs. The history of the Wassermann reaction illustrates the complicated interaction between "scientific facts" and "social facts", and the mutual shaping of both.
