Experience, Analogy and Mechanism in Maupertuis’s Theory of Generation
At the mid-eighteenth century, the formulation of alternative theories undermined the hegemony of preexistence in the debate on animal generation. The new theories were characterized by a revival of epigenesis, and by a naturalization of the explanatory models. A key text in the mid-century renaissance of epigenesis is Pierre-Louis Moreau de Maupertuis’s "Vénus physique" (1745). While interpreters have unanimously acknowledged the role of this text in changing the course of the debate, the reasons for Maupertuis’s originality have not been studied in depth. Also, the relationship between the "Vénus physique" and the mechanistic view of generation is not entirely clear. With respect to the first point, I argue that Maupertuis is original in the theoretical framework he develops. He adopts a strongly empiricist stance and is skeptical about the possibility of the human intellect attaining a reliable knowledge of nature. As for the second point, I show not only that the reference to mechanism, and to Descartes’s work, is important in defining the terms of the controversy over preexistence. The appropriation of the mechanistic view, its updating, and eventual dismissal, are also important passages in the constitution of Enlightenment embryology, fostering the rise of a materialist approach in the 1750s.

La présence de Descartes dans la Vénus physique de Maupertuis : Réappropriation et critique
Nous nous proposons d’offrir de nouvelles pistes de réflexion sur la présence de Descartes dans les sciences de la vie au XVIIIe siècle à travers l’analyse de la Vénus physique (1745) de Maupertuis. Nous introduisons d’abord la critique que Maupertuis fait de la préexistence. Nous discutons ensuite des théories de la génération de Descartes et de Maupertuis, en soulignant la réappropriation du cartésianisme par ce dernier, ainsi que sa tentative de « mettre à jour » l’explication cartésienne.
Cartography, Geodesy, and the Heliocentric Theory: Yves Simonin’s Unpublished Papers
Yves Simonin, a rather obscure professor of hydrography in Bayonne, submitted five scientific papers to the Paris Academy of Sciences between 1738 and 1740, which only survive in the original manuscript versions. The topics Simonin deals with in these texts are essentially three: the rectification of navigation charts of the Southern Sea, the shape of the Earth, and the heliocentric theory. Far from acknowledging Simonin's contribution to the ongoing academic debate as a valuable one, the institution systematically rejected his work. In this paper, I first provide a critical analysis of Simonin's manuscripts. As I argue, their originality lies in the adoption of the perspective of a practitioner of and expert in navigational techniques. I then investigate the reasons behind the Academy's negative reception of Simonin's papers, casting light on the expertise required to participate in academic debates in the mid-18th century, and on the limits set by the institution to the possibility of external intervention.
Maupertuis. Le philosophe, l’académicien, le polémiste
Aujourd’hui presque oublié, Pierre-Louis Moreau de Maupertuis (1698-1759) est pourtant une figure majeure de la vie intellectuelle et institutionnelle du siècle des Lumières. Cet ouvrage se propose de renouveler l’image du savant en approfondissant certains aspects saillants de sa vie et de son œuvre, et de lui restituer ainsi la place qu’il mérite dans l’histoire de son siècle. Il s’agit notamment d’interroger la genèse et l’évolution de sa pensée philosophique, en dévoilant l’originalité de son épistémologie et de sa métaphysique. L’identité du « Maupertuis philosophe » se construit en parallèle avec celle de l’« académicien » et du « polémiste ». C’est pourquoi ce volume consacre aussi un large espace à l’étude des milieux académiques où Maupertuis travailla, à Paris comme à Berlin, ainsi qu’aux controverses auxquelles il prit part.
