Thing-in-itself#
Summary#
The “thing-in-itself” represents the metaphysicians’ supposed realm of pure, uncorrupted Being where values like truth and goodness originate, contrasted with the illusory world of appearances. Nietzsche critiques this concept as a fundamental prejudice, arguing that the belief in such antitheses between a true world and an apparent world is unfounded. He further contends that claims to know the “thing-in-itself” through immediate certainty involve a contradiction in terms, since all cognition necessarily involves falsification by both subject and object.
