 Some minimal standards of adequacy immediately suggest themselves (Butchvarov 1995, 75). Whether one takes a realist or descriptivist approach to providing a system of categories, if that system is supposed to be comprehensive, it clearly must meet at least the standard of being exhaustive – providing a category for everything there is (on the realist approach) or might be (on the descriptive approach). Nonetheless, one may, as Hoffman and Rosenkrantz (1994, 140) do, present a system of some fundamental categories without taking it to be exhaustive.
