As an alternative to an abstractist-concretist divide, a pluralist ontology (per Danto 1993), allows “material bases” and “aesthetic ideas” as different sorts of architectural objects. Goodman’s account (1968/1976) lends itself to a pluralist, or at least aspectual, reading. He suggests that, but for certain conditions unmet, an architectural object could be identified as those structures that perfectly realize a corresponding plan or other suitable architectural notation (see §4). On his nominalist view, the objects turn out to be the built structures but an available realist interpretation—which may better accommodate the multiples that are key to his story—takes the objects to be the class of such structures.
