What is Really Wrong with Ontic Structural Realism? On the Possibility of Reading off Ontology from Cur-rent Fundamental Science

I argue that the central conflict between epistemic and ontic versions of structural realism concerns whether it is possible to read off ontology from current fundamental science. Even if we assume that structures are metaphysi-cally superior to objects, the possibility of reading off ontology from current fundamental science remains unjustified. I show that the conclusion as regards the reading off ontology in the ontic version is already assumed in one of the premises; hence the argument begs the question. As a result, the problem of ontological discontinuity implied in the pessimistic meta-induction argument remains intact in ontic structural realism.
