 As regards  [i],  at least given certain general assumptions about semantic values, truth conditions, and compositionality  (§2.2),  natural language ontology is an integral part of theoretical linguistics and thus as important to pursue as theoretical linguistics itself. Theoretical linguistics has grown enormously over the last 70 years providing a wealth of semantic and syntactic generalizations and theories, which permits a more systematic and accurate use of natural language for metaphysical purposes. When pursued within the context of theoretical linguistics, natural language ontology will also set its own ambitions regarding universals, the alignment of ontology with syntax, the relation of ontology to lexical semantics, and the connections of the ontology reflected in natural language to that reflected in cognition.
