We always adopt perspectives by default, whether we are aware of it or not, and the individual concepts of existence are defined by the circumstances surrounding that individual. Truth is made by and for individuals and peoples. This view differs from many types of relativism which consider the truth of a particular proposition as something that altogether cannot be evaluated with respect to an "absolute truth", without taking into consideration culture and context.
This view is outlined in an aphorism from Nietzsche's posthumously-assembled collection Will to Power.
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.
José Ortega y Gasset has conceived of a potential sum of all perspectives of all lives which could produce an "absolute truth".
