Abstract: This article exposes the Adorno’s critique to the aesthetics focused on the subject and its affirmative or negative relationship to the desire of Kant and Freud from a revision of the objective and dialectical conception of Hegel’s aesthetics which, in turn, is criticised and increased from a reading of the Freudian unconscious as “possible knowledge”. All of that wants to contribute to clarify the Adorno’s conception of art as an unconscious writing of history.
