Richard Schacht, in his interpretation of Nietzsche's thought, argues that this can be expanded into a revised form of "objectivity" in relation to "subjectivity" as an aggregate of singular viewpoints that illuminate, for example, a particular idea in seemingly self-contradictory ways but upon closer inspection would reveal a difference of contextuality and of rule by which such an idea (e.g., that is fundamentally perspectival) can be validated. Therefore, it can be said each perspective is subsumed into and, taking account of its individuated context, adds to the overall objective measure of a proposition under examination. Nevertheless, perspectivism does not implicate any method of inquiry nor a structural theory of knowledge in general.
