ABSTRACT
This chapter shows how objects are built out of powers. Instances of physical powers are generally assumed in the literature to be qualitatively and numerically atomic that is simple, like property tropes. The differentiation between the structural and the substantial power of an electron enables, to understand the relation between the extensional mereological conception of the electron and the substantialist conception of the electron. The constitution relation turns the powers in the physical structure into properties of the emergent substantial power. The difference between structural powers and substantial powers has not been placed on the map in the history of metaphysics or in current metaphysics so far. Power Structuralism is a powers only ontology, at the fundamental level, with no causally inert entities in it. It has a number of distinctive features that differentiate it from alternative power ontologies in the literature.
