 Distinguishing implicit acceptance of an ontology through the use of language from metaphysical reflection does of course not prevent the latter to come into play when building a theory of the ontology reflected in natural language. Natural language data may provide only a partial specification of a particular ontological notion so that metaphysical reasoning would fill in the rest—at least on a view on which natural language ontology is also part of metaphysics and not just linguistics (cf.  §1.1),  and metaphysical reasoning may give independent support for ontological notions reflected in natural language.
