 By contrast, metaphysical “dual aspect” interpreters take the distinction to carry more metaphysical weight. They interpret the appearance/thing in itself distinction as a metaphysical distinction between two different classes of properties had by objects, for instance, their relational properties and their intrinsic properties. Appearances are objects qua bearers of “empirical properties” (e.g., relational properties) while things in themselves are the very same objects qua bearers of “noumenal” or “non-empirical” properties (e.g., intrinsic properties). The next two sub-sections explore the epistemological interpretation of Henry Allison. The remainder of the sections concerns metaphysical “dual aspect” readings, focusing on the widely discussed interpretation of Langton (1998).
