Towards a new phase of Du Châtelet scholarship: from Institutions de Physique (1740) to Institutions Physiques (1742)

Abstract

Abstract There is a mysterious two-fold change in Du Châtelet’s position on Newtonian attraction: from acceptance thereof as an explanatory principle in Essai sur L’Optique (ca. 1938-1939), to rejection in the 1740 Institutions, and returning to acceptance again in her Commentary (1756) to Newton’s Principia. In this paper, I suggest that we turn to the 1742 Institutions for answers. There, Du Châtelet introduces physical explanation and maintains that we can appeal to certain physical qualities (such as attraction) for explanatory force. Using this case study, I argue that the scholarship will benefit greatly from turning to the 1742 edition going forward.
