Relations All the Way Down? Against Ontic Structural Realism

According to Ladyman, the world consists of nothing more than relations that relate to no particulars. Could the world be nothing but structure? In this chapter it is argued that even though there are a number of problems with the standard view of relations accompanied by a particularist ontology, substituting for it a world of pure structure is not progress. A world of pure structure would be no more than a Platonic entity, lacking any resources for concretization. Consequently, there would be no possibility of distinguishing between a world-kind and its concrete instance or instances. It is also argued that the view has insufficient empirical motivation. The history of science does not support the claim that structure is preserved through theory change nor that the structural components of a theory are extricable from its ontological commitments.
