 Averroes explicitly backs Alexander’s account that Book VI follows Book V because the beginning of the former makes use of the “descriptions” of the continuous, contiguous and next in succession objects that were set up in Book V (LC 246L T1). Aristotle strives to prove that a continuum cannot be composed of indivisibles, and he gives the example of the line, because a line cannot be composed of points. The cause for the continuum in magnitude, spatial extension (megethos) is pleaded with various arguments, and it is shown that time and motion are continuous too (Phys. VI.1, 231a21–233b32). They are always divisible.
