 The core-periphery distinction in natural language ontology would be important also for the quest for universals of natural language ontology. Only the core reflects metaphysical intuitions, which are generally held to not display interpersonal inconsistency (see entry on  intuition).  This means that only the core, not the periphery can represent a form of universal language-related ontology. Of course, the general presupposition that intuitions show no interpersonal inconsistency may be in error, and so may be the assumption that the ontology of the core is universal rather than showing language-particular differences.
