 Averroes does not accept the possibility of motion as addable or deductible and insists in the oneness. In the Long Commentary he develops the principle. The issue of motion in the void occupies LC 158L–162C T71, and there Averroes expounds Avempace’s commentary making it known to the Latin philosophers, and Thomas of Aquinas adopted the latter’s view. Averroes knows that Avempace objected that if motion needed a medium so that it happens in time, the celestial spheres would rotate in no time (LC 160D TC71; Avempace [SST], 116: 6–18]).
