 Philosophers and non-philosophers when engaging in ontological reflection may use or introduce expressions specifically meant to convey their own ontological views. But such (uses of) expressions are never considered indicative of the ontology implicit in natural language. Yet they should come with a semantics as well, and may have to be assigned as semantic values entities or properties, even if fictional, in order to be integrated within a single compositional semantics of the language. Still a distinction needs to be maintained, in some way, between what is implicitly accepted as part of our linguistically manifest intuitions (non-technical expressions with their ordinary meaning) and what is added on through reflection.
