 Alexander of Aphrodisias objected because place is related to quantity: Place is equal to the thing that it contains. If a body moves, it moves into a place that is equal to it, and for this reason form or matter are in place essentially. Alexander’s commentary on the Physics has not reached us, and we have to rely on Averroes’ account. He admits: “that which Alexander said is not free of doubt” (LC 129F).
