 In spite of the hesitation caused by the wrong term, Averroes interpreted that Aristotle distinguished here between a mover setting in motion as a final cause or as an efficient cause (quasi agens), and that Book VIII would clarify the matter concerning the first mover. He was even more certain in asserting that Book VIII would inquire about first motion, whether it is eternal or generated, and he rejected Themistius’ view that Book VII was superfluous for this reason.
