Abstract

Aquinas is standardly thought to endorse a hylomorphic account of change—that is, one on which all change can be analyzed in terms of the reception of distinct forms by matter. But Aquinas’s views about local motion raise a serious problem for this interpretation. Local motion, as he understands it, is a type of change that cannot be analyzed in hylomorphic terms. In this paper, I examine Aquinas’s views about change and local motion with the aim of clarifying and resolving this problem. In doing so, I provide a novel interpretation of these same views and highlight their implications for Aquinas’s understanding of several related issues—including extrinsic denomination, spatial location, potentiality, actuality, and efficient causation.
