Due to its favorable reception circa 1970, the essay “Truth and Lies in a Nonmoral Sense” has solidified Nietzsche's monumental status within the field of rhetoric and writing studies, allowing those inheriting this perspective to put the essay to use without attending to its intertextual background.
