 Second, there is the objection from interpenetration, according to which an entity x is in some cases exactly located at a subregion of the exact location of an entity y despite the fact that x is not a part of y. For example, two bosons (or tropes or…) might have the same exact location without being parts of each other. (See Section 4 for further discussion.) If the objection from interpenetration is correct, then locational subregionhood is not sufficient for parthood
