 Malebranche was not the first Cartesian to endorse occasionalism. There were followers of Descartes such as Louis de la Forge (1632–1666) and Claude Clerselier (1614–1684) who stressed that God must be the cause of the communication of motion in bodily collisions given the passivity of Cartesian matter. Clerselier in particular attempted to preserve some room for the action of finite minds on bodies, but the Cartesian Geraud de Cordemoy (1626–1684) went further in claiming that only God can cause changes in the material world. However, none of these thinkers went as far as Malebranche in arguing explicitly that God must produce all real changes in nature. Moreover, Malebranche is distinctive in providing an explanation of God’s action that distinguishes His general will from His particular volitions. For a recent discussion of issues connected to Malebranche’s notion of particular volitions, see Walsh and Stencil (2016).
