Abstract
This short essay constitutes a vindication of Adorno’s work on Beethoven as a profound text that sheds light on the understanding of the Frankfurtian’s thought. It will focus on the conclusions to which the late Beethovenian compositional technique leads and its role in a reconception of reason that represents a model from which to base a 21st century philosophy. It will start from the distinction made by Adorno of the different ways that Beethoven, throughout his styles of composition, elaborated to confront or, rather, approach different moments and compositional techniques within a sonata form, delving into how those uses by the Late Beethoven were an influence on Adorno’s thought, to the point of hiding the key to the adornian problem: the overcoming of the Enlightenment through the Enlightenment itself
