Cette contribution se place dans le contexte de la réception du calcul infinitésimal de Leibniz chez un cercle de mathématiciens réunis autour du philosophe Nicolas Malebranche au tournant du xviie siècle. Ces mathématiciens ont déjà entrepris un renouveau de leurs connaissances et ce n’est donc pas en terres vierges qu’ils s’approprient de l’invention leibnizienne. Manuscrits à l’appui, nous examinons les variations épistémologiques que subit le concept de polygone infinitangulaire à travers la nouvelle pratique d’écriture que représente le calcul leibnizien mais en tenant compte des formes d’intertextualité mises en œuvre par les acteurs.Cairn free access |

As early as the first publications of his differential and integral calculus, Leibniz stated that the essential principle for studying a curve was to consider it as an “infinitangular polygon” or a “polygon of infinitely many sides.” This supposition is not entirely original in the history of mathematical practice, but Leibniz claims that, in the context of his invention, it is the one that ultimately leads to a general concept of a curve. This contribution is presented in the context of the reception of Leibniz’s calculus by a circle of mathematicians around the philosopher Nicolas Malebranche at the turn of the 17th century. These mathematicians had already undertaken a renewal of their skills, and so they did not appropriate Leibniz’s invention in virgin territory. Based on manuscripts, we examine the epistemological variations undergone by the concept of the infinitangular polygon through the new practice of writing represented by the Leibnizian calculus, as well as the forms of intertextuality employed by the actors. |
