The author argues that the Frankfurt School’s critique of phenomenology as the theory of cognition (as defined by Theodore W. Adorno) is unjustified. The article is divided into five main parts. In the first part, historical, as well as theoretical relations between the two philosophical currents are reconstructed. In the second part, Adorno’s critique of the theory of cognition is defined with regard to Husserl’s phenomenology in particular. The third part of the article analyses why Adorno’s critique seems to be unjustified. The author shows that Husserl denied the theses which Adorno criticized. In the fourth part, the author enlarges the argument by showing that Husserl’s critique of scientific rationality is similar with Adorno’s proposition. Nonetheless, in the fifth part the author stresses main differences between the two critiques of rationality. .
