Abstract

In his paper, Josh Hayes argues that inclination (ῥοπή) is the nature of each element. It is an active and passive principle that explains why the elements move to their proper places. Thus, according to Hayes, by introducing inclination in De Caelo IV 1, Aristotle posits a single explanatory factor that accounts for all elemental motions. By doing so, he answers the question, posed in Physics VIII 4, of what the cause of elemental motion is. In my comments, I will contest these claims. Aristotle’s theory of elemental motion does not rely on a single explanatory factor; yet, it is not, as Hayes claims, incoherent. Instead, the different strands merely reflect the special nature of the elements.
