In the context of recent attempts to more adequately engage with Adorno’s approach to sociology and social theory, this article argues that such a project requires a more complete understanding of the philosophical basis of Adorno’s critical material perspective on knowledge and language. In particular, the interpretation of Adorno within sociology has been hampered by a fundamental misunderstanding regarding his methodology of critique and composition, which prioritizes the content of Adorno’s claims regarding sociology and social theory, over their rhetorical and (...) performative character. This character is identifiable in Adorno’s prose, and grasped through a close attention to his account of the negative dialectic. Using Bernstein’s articulation of the ‘complex concept’ as an analytical framework, and Adorno’s introduction to Durkheim as its material, the article argues that the inability to grasp the rhetorical character of Adorno’s critical interpretive approach prevents an understanding of his potential relevance for sociology and social theory.
