All noun-substantives name entities, which divide into perceptible-inferential and real-fictitious.

Evidence

An entity is a denomination in the import of which every subject matter of discourse, for the designation of which the grammatical part of speech called a noun-substantive is employed, may be comprised. … Entities may be distinguished into perceptible and inferential. … An entity, whether perceptible or inferential, is either real or fictitious. — Jeremy Bentham, The Panopticon Writings, 343
