Once one learns how to speak a language, the authority of the language has fulfilled its aim, but is not thereby overcome. Authority remains as the entry to the inquiry one has undertaken. It is not overcome or passed by so much as it is actualized, fulfilled. That is why philosophic reformations seem too often to be nested within what it is they seek to reform. Insofar as it begins from its predecessor, every attempted reformation is only the confession of the authority of its predecessor's discourse. The appearance of abrupt 'revolutions' in philosophy is produced only by ignoring, sometimes ingenuously, the authority of previous speech.
