 First and foremost, there is an important distinction in Wolff’s cosmology between “general space” and “particular space”. Particular space (or a given place) is what an extended body “fills” or “occupies” by virtue of its corpuscular parts (Cosm. §§122–4). Its reality is derivative of the interacting atomic elements that give rise to individual corpuscles. For Wolff, a corpuscle’s place simply results from a corpuscle’s extension. A given place is conceived as an imaginary immobile container that has the same dimensions as the extended thing that occupies it (Ont. §§676–9). General space, in contrast, is conceived as the perceived order of coexisting bodies. As explained above, the existence of bodies is established by Wolff experientially and amounts to an instance of historical cognition. In §45 and §46 of his German Metaphysics, Wolff explains:
