@article{Schaffer2009-SCHSTO-7,abstract = {What is the relation between material objects and spacetime regions? Supposing that spacetime regions are one sort of substance, there remains the question of whether or not material objects are a second sort of substance. This is the question of dualistic versus monistic substantivalism. I will defend the monistic view. In particular, I will maintain that material objects should be identified with spacetime regions. There is the spacetime manifold, and the fundamental properties are pinned directly to it},author = {Jonathan Schaffer},title = {Spacetime the One Substance},volume = {145},pages = {131--148},number = {1},year = {2009},journal = {Philosophical Studies}}@
