One of the arguments against ontic structural realism (OSR) is that it cannot explain causation. The critics claim that causation is rooted in objects but an appeal to objects is inconsistent with a structuralist position. In his recent defense of OSR, M. Esfeld puts forward a proposal according to which causal powers are built directly into relations and, therefore, promises us to shed a structuralist light on causality. However, Esfeld combines causal view of relations with his moderate version of OSR that, in order to avoid some conceptual difficulties, contains a structural view of objects. The aim is to demonstrate that this account faces a dilemma and that an attempt to resolve it reveals further difficulties that question a position of moderate OSR as a real alternative to, for instance, radical OSR or the bundle theory.
