 So for instance, Avicenna denied that the universe has a place, but he likewise further denied that the list of the types of motion exploited by Philoponus in his dilemma is exhaustive: one must further add to that list, maintained Avicenna, motion with respect to the category of position (Avicenna 1983, II.3, 103–105.13; McGinnis 2006b). According to Avicenna, then, all cases of rectilinear motion, that is, motion from some spatial point x to a distinct spatial point y, are cases of motion with respect to the category of place, whereas all cases of spinning or rotating, where the moving object does not depart from a given spatial location, are cases of motion with respect to the category of position. Since the universe during its daily rotation does not depart from one spatial location to another it does not need a place and yet it can still move albeit with respect to the category of position, concluded Avicenna.
