 One further way of being a permissivist is by permitting a multitude of parts of ordinary objects that we do not naturally judge them to have. For instance, one might hold that, in addition to ordinary parts like arms and legs, you have extraordinary parts like leg complements, where your left-leg complement is an object made up of all of you except for your left leg. Together with some natural assumptions (e.g., about regions of space), leg complements and a legion of other extraordinary parts will be delivered by the doctrine of arbitrary undetached parts—or DAUP—the thesis that for any material object o, if r is the region of space occupied by o, and if r′ is an occupiable sub-region of r, then there exists a material object that exactly occupies r′ and which is part of o. (Roughly: for every region of space within the boundaries of a given a object, that object has a part that exactly fills that  region.)[10]
