Abstract

This essay will focus on analogies drawn from Aristotle’s account of natural motion and change which Thomas Aquinas uses to construct responses and explanations of free choice and its characteristic act, i.e. creation for God, and acts of virtue for human beings. Though these analogies to natural change recur throughout the Thomistic corpus, my analysis will focus on their use in the Summa Theologiae, where they consistently bear the weight of Aquinas’s account of the divine and human will and their acts, and tend to be used to minimize the differences between the elements, animals, human beings, and God by relating them as being which tend to, move toward, act for, and are themselves an end. In contrast to De veritate and other texts, in which categories and examples of physical change are used to distance and distinguish human or divine willing and action from motion and change, the Summa attempts to build up from the ground of material natures and change toward the human and divine in gradual steps, transforming the gap and opposition separating creature from creator into a gradual ascent.
