About: Immaculate perception

The expression immaculate perception, used by the German philosopher Friedrich Nietzsche in his text Thus Spoke Zarathustra; the term pertains to the idea of "pure knowledge." Nietzsche argues that "immaculate perception" is fictional because it ignores the intimate connection between the perceiver and the external world. He argues that humans are fallible and are capable of using data to ratify or refute perceptions. He also clarifies that perception is value-laden and can be ruled by our interests.
