Abstract
I argue in this paper that Descartes is committed both to a compatibilist view concerning the relation between free will and divine preordination, namely, one according to which both of these views come out true, and to a libertarian view as regards human free will. I defend here that what allows our author to maintain both of these committments is what I call Mysterism, namely, the view according to which God's immense and incomprehensible nature explains our incapacity to understand fully that compatibility through our own finite reason.
