Ontological disunity and a realism worth having
Clarke S.
Ross & Spurrett (R&S) appear convinced that the world must have a unified ontological structure. This conviction is difficult to reconcile with a commitment to mainstream realism, which involves allowing that the world may be ontologically disunified. R&S should follow Kitcher by weakening their conception of unification so as to allow for the possibility of ontological disunity.
