 Abner distinguishes between the physical object and extension or dimension. According to Abner, dimension is “a simple and subtle quantity detached from all movable bodies”; in other words, it is space, independent of any physical body. Dimension is measurable per se, and is not linked to what occupies it. Nevertheless, Abner’s definition of place is still associated with body: “place” is the dimension occupied by a body, and it is the body that turns it into “place.” According to Abner, the movement of bodies is not due to their being attracted to some place where they must rest before resuming their movement; rather, they move because of the interaction of several forces, quite independent of any particular place. A body that is thrown upward rises, but if it suddenly begins to fall because of an opposing force, there would not be a moment of rest between the two opposing motions.
