Aquinas: Disputed Questions

This present article examines an argument in Aquinas’s De potentia, q. 3, a. 9, in which Aquinas argues that the human soul must be created by God. After introducing the relevance of the problem and discussing the state of the literature, I lay out Aquinas’s argument and defend it by appealing to his broader metaphysical commitments. I then turn to two difficulties raised in the literature by B.C. Bazan and Lawrence Joseph Kaiser. Bazan argues that Aquinas’s claim that the human (...) soul must be created by God leads to internal inconsistencies within Aquinas’s metaphysical system. While not explicitly criticizing Aquinas, Kaiser’s account of the eduction of forms from matter also raises a few problems for the consistency of Aquinas’s claim. In response to Bazan and Kaiser, I argue that a firm grasp of Aquinas’s semantics dissolves the criticisms. (shrink)

The goal of this paper is to show that Thomas Aquinas, in his _Disputed Questions on Evil_, presents a theory of free will that is compatibilist but still involves a version of the principle of alternative possibilities (PAP) and even requires alternative possibilities for a certain kind of responsibility. In Aquinas’ view, choosing between possibilities is not the primary power of the will. Rather, choice arises through the complex interaction of various parts of human psychology, in particular through the indeterminacy (...) of the intellect and through the interaction between reason and passion. Both of these ways provide cases where Aquinas not only allows for alternative possibilities but thinks that they are necessary for moral responsibility, all the while remaining, strictly speaking, a compatibilist.
