 Burley was persuaded that Ockham’s objections are sufficient to show that the traditional realist account of the relation between universals and particulars is unacceptable, but not that realism as a whole is untenable. Thus, in his later years he developed an ontology of macro-objects based on a threefold real distinction between categorial items or simple objects and state of affairs (his propositiones in re), between universals and individuals, and among the ten categories.
