Abstract

Aristotelianism remained the dominant influence on the course of natural philosophy taught at the University of Paris until the 1690s, when it was swiftly replaced by Cartesianism. The change was not one wanted by church or state and it can only be understood by developments within the wider University. On the one hand, the opening of a new college, the Collège de Mazarin, provided an environment in which the mechanical philosophy could flourish. On the other, divisions within the French Catholic Church between Austinians and Molinists led to Cartesianism finding support within an important section of the faculty of theology, which was the traditional guardian of philosophical orthodoxy. The conversion of the University of Paris to Cartesianism had important consequences. It encouraged similar changes to the natural philosophical curriculum throughout France and affected the structure and raison d'être of the Académie des Sciences
