Do objects depend on structures?

Abstract

Ontic structural realists hold that structure is all there is, or at least all there is fundamentally. This thesis has proved to be puzzling: What exactly does it say about the relationship between objects and structures? In this article, I look at different ways of articulating ontic structural realism in terms of the relation between structures and objects. I show that objects cannot be reduced to structure, and argue that ontological dependence cannot be used to establish strong forms of structural realism. At the end, I show how a weaker, but controversial, form of structural realism can be articulated on the basis of ontological dependence. © The Author 2011.
