Hasard et probabilité sont des concepts importants dans l’épistémologie de Poincaré, malgré les difficultés qu’ils introduisent. La notion de hasard est conçue dans un scénario conceptuel où le déterminisme règne encore; la probabilité, à son tour, est toujours basée sur un ensemble de conventions et d’hypothèses qui cherchent à surmonter l’incertitude qui menace la connaissance scientifique. L’article consiste en une approche philosophique qui vise à clarifier ces notions à partir du point de vue de l’épistémologie de Poincaré et de montrer (...) que le hasard trouve sa place dans les constructions théoriques lorsqu’il est instancié par les ressources du calcul des probabilités.

Probability plays a crucial role regarding the understanding of the relationship which exists between mathematics and physics. It will be the point of departure of this brief reflection concerning this subject, as well as about the placement of Poincaré’s thought in the scenario offered by some contemporary perspectives.

Este texto introduz a tradução do discurso de intitulado "Sobre os números transfinitos" ("Über transfinite Zahlen"), proferido por Henri Poincaré em 27 de abril de 1909, na Universidade de Göttingen. Após uma breve apresentação do pensamento do autor acerca dos fundamentos da aritmética, procura-se citar os aspectos mais relevantes da chamada crise dos fundamentos da matemática, para então introduzir a reformulação do conceito de predicatividade aventada no referido discurso sobre números transfinitos, contribuição compreendida como um recurso teórico necessário para a (...) superação dos paradoxos relativos à teoria dos conjuntos. Com isso, pretende-se evidenciar o papel central do texto publicado nesta edição para o desenvolvimento da concepção matemática de Henri Poincaré. This article provides an introduction to the translation of the lecture entitled "On transfinite numbers" ("Über transfinite Zahlen"), given by Henri Poincaré at the University of Göttingen on April 27, 1909. Following a short presentation of Poincaré's views on the foundations of arithmetic, it identifies the aspects of the so-called crisis of the foundations of mathematics that are most relevant for understanding his reconstruction of the concept of predicativity, which is intended to be a theoretical resource that may overcome the paradoxes of set theory. In doing so, the article highlights the central role of this text in the process of maturation of Poincaré's views on the foundations of mathematics. (shrink)

En synthétisant l'histoire et en méditant l'idéal, la philosophie du droit se fait l'intermédiaire entre l'une et l'autre et assure le progrès du droit. De cette position découle sa fonction pratique ; autrement dit la philosophie du droit enseigne et prépare la reconnaissance pratique de l'idéal juridique. Dans tous les temps elle s'est acquittée de cette fonction et les œuvres des grands philosophes du droit sont liées à tous les grands progrès civils. [...] Elle n'est donc pas un exercice stérile (...) et vain, mais répond aux exigences naturelles et constantes de l'esprit humain, à une de ses fins intrinsèques. Avec l'éveil de la conscience critique, apparaît le besoin de rechercher si les devoirs imposés sont justes, si l'autorité qui commande, commande selon la raison ; et la philosophie du droit commence précisément par l'antithèse entre juste naturellement et juste légalement.

ABSTRACTThis article draws attention to the presence of a previously unnoticed transliterated telestich in the transformation of stones into bodies in the episode of Deucalion and Pyrrha in Ovid's Metamorphoses. Detection of the Greek intext, which befits the episode's amplified bilingual atmosphere, is encouraged by a number of textual cues. The article also suggests a ludic connection to Aratus’ Phaenomena.
