"The French philosopher Nicolas Malebranche popularized the doctrine of occasionalism in the late seventeenth century. Occasionalism is the thesis that God alone is the true cause of everything that happens in the world, and created substances are merely "occasional causes." This doctrine was originally developed in medieval Islamic theology, and was widely rejected in the works of Christian authors in medieval Europe. Yet despite its heterodoxy, occasionalism was revived starting in the 1660s by French and Dutch followers of the philosophy of René Descartes. Since the 1970s, there has been a growing body of literature on Malebranche and occasionalism. There has also been new work on the Cartesian occasionalists before Malebranche - including Arnold Geulincx, Geraud de Cordemoy and Louis de la Forge. But to date there has not been a systematic, book-length study of the reasoning that led Cartesian thinkers to adopt occasionalism, and the relationship of their arguments to Descartes' own views. This book expands on recent scholarship, to provide the first comprehensive account of seventeenth century occasionalism. Part I contrasts occasionalism with a theory of divine providence developed by Thomas Aquinas, in response to medieval occasionalists; it shows that Descartes' philosophy is compatible with Aquinas' theory, on which God "concurs" in all the actions of created beings. Part 2 reconstructs the arguments of Cartesians - such as Cordemoy and a Forge - who used Cartesian physics to argue for occasionalism. Finally, it shows how Malebranche's case for occasionalism combines philosophical theology with Cartesian metaphysics and mechanistic science"--

Sandrine Roux's L'Empreinte cartésienne addresses what she describes as one of the "persistent problems" in philosophy, namely, the mind-body problem raised by Descartes's substance dualism. Her book carefully lays out the various puzzles, both real and perceived, raised by Descartes's theory of humans as a mind-body union. She distinguishes clearly between the way these problems are understood by Descartes, and the way they were seen by some of his seventeenth-century followers, especially the occasionalists, Louis de La Forge, Géraud de Cordemoy, and Malebranche. And she tries to orient the Cartesian mind-body problem with respect to theories in contemporary philosophy of mind.The first two parts are...

This paper is the first of a two-part reexamination of causation in Descartes's physics. Some scholars ? including Gary Hatfield and Daniel Garber ? take Descartes to be a `partial' Occasionalist, who thinks that God alone is the cause of all natural motion. Contra this interpretation, I agree with literature that links Descartes to the Thomistic theory of divine concurrence. This paper surveys this literature, and argues that it has failed to provide an interpretation of Descartes's view that both distinguishes his position from that of his later, Occasionalist followers and is consistent with his broader metaphysical commitments. I provide an analysis that tries to address these problems with earlier `Concurentist' readings of Descartes. On my analysis, Occasionalism entails that created substances do not have intrinsic active causal powers. As I read him, Descartes thinks that bodies have active causal powers that are partly grounded in their intrinsic natures. But I argue ? pace a recent account by Tad Schmaltz ? that Descartes also thinks that God immediately causes all motion in the created world. On the picture that emerges, Descartes's position is both continuous with, and a subtle departure from, the Thomisitic theory of divine concurrence

This study offers a new account of the development of Cartesian Occasionalism. The doctrine of Occasionalism - most famously advocated by Nicolas Malebranche - states that God alone is the cause of every event, and created substances are merely "occasional causes." In the years following René Descartes' death in 1650, several of his followers -- including Arnold Geulincx, Gerauld de Cordemoy and Louis de la Forge - argued for some version of this thesis. My study builds on recent scholarship about these first Cartesian Occasionalists, the motives that led them and Malebranche to adopt Occasionalism, and the connections between Occasionalism and the views of Descartes. I analyze the doctrine of Occasionalism, and examine its relationship to Descartes' philosophy. I argue that Descartes' views in physics and metaphysics are consistent with the claim that corporeal substances have intrinsic causal powers, and reply to arguments by Gary Hatfield, Janet Broughton and Daniel Garber that purport to show otherwise. I examine how Occasionalism relates to several proposed problems with Descartes' claim that the human mind causally interacts with the human body, and argue that Occasionalism is not the "natural" solution to these problems. I conclude by canvassing the arguments of the earliest Cartesian Occasionalists. I argue Cartesian Occasionalism was neither an ad hoc solution to the mindbody problem, nor a logical consequence of Descartes' own views, but rather an attempt to extend and better systematize Cartesian philosophy.
