 Spatial nonseparability  —the denial of spatial separability—is also closely related to  physical property holism.  At least classically, spatial relations are the only clear examples of qualitative intrinsic physical relations required in the supervenience basis for physical property determination/holism: other intrinsic physical relations seem to supervene on them, while any instance of physical property holism due to the spatial separation of basic physical parts would entail spatial nonseparability. But if one thought a spatially localized object has a determinate value for a magnitude like mass only by virtue of its mass relations to other such objects elsewhere then one might decide to include those relations in the supervenience basis also (see Dasgupta (2013)).
