Whenever approaching any phenomenon, Adorno’s procedure is one of immanent dialectical critique. The phenomenon is treated as not accidental or arbitrary but as a necessary form of appearance that points beyond itself, indicating conditions of possibility for change. It is a phenomenon of the necessity for change. The conditions of possibility for change indicated by the phenomenon in question are explored immanently, from within. The possibility for change is indicated by a phenomenon’s self-contradictions, which unfold from within itself, from its own movement, and develop from within its historical moment.
HORKHEIMER’S REMARKABLE ESSAY “On the sociology of class relations” (1943) is continuous with Adorno’s contemporaneous “Reflections on class theory” (1942) as well as his own “The authoritarian state” (1940/42), which similarly mark the transformation of Marx and Engels’s famous injunction in the Communist Manifesto that “history is the history of class struggles.”
