Causation and Structural Realism

M. Esfeld has recently argued that ontic structural realism may succeed only if it is based on causal structures. In order to meet this requirement, he offers a combination of dispositional/causal relations with moderate form of ontic structural realism. This paper, however, demonstrates that moderate position, in relation to causation, faces a dilemma whose resolution leads to a monistic ontology that creates a rather hostile environment for structural metaphysics
