 Averroes reminds us that in Book VII, Aristotle says that the proper subject of change and motion is body, not its matter or its form. Matter and form are in place accidentally and “it is not impossible that place is in place accidentally, per accidens” (LC 129C). What is accidental divides into two categories, always accidental or rarely so. Matter and form always move together with the body, therefore place belongs to the category of always accident, and if it is constant, place is in place all the time, but it is obvious that place is not always in place, either essentially or accidentally. The argument makes an exception: the place of the outermost body, the place embracing the last body, because it moves together with the outermost body, and in this case it is in place accidentally and raro, rarely (LC 129E).
