 Book VII begins with the statement “Whatever is moving must be moved by something” (Phys. 241b24), and Averroes comments on it: “In this treatise [Aristotle] searched whether every movable has a mover”, and he points out that Aristotle has in mind those movables in which the mover is not clearly distinguished from the movable, “as in the four elements” (ut in, LC Schmieja 1:20–2:1; absque, “except for”, LC 306B  T1).[11]
