Abstract
The article analyses the 'post-secular turn' in critical theory by comparing Jürgen Habermas' late philosophy with the philosophy of his predecessor Theodor W. Adorno.
It poses the question to what extent can Habermas be seen as a post-secular theorist when setting his work against that of Adorno? Following Birgitte Schepelern Johansen, the author develop a concept of post-secularism as a move beyond the strict division between religion and non-religion, and apply the concept to the work of the two critical theorists in question. Finally, Adorno's work is identified as a 'religious secularism' and Habermas' work as a 'post-secular secularism'.
Thus, the author points out the ambivalence, which the alleged 'post-secular turn' breeds, and suggest a reconsideration of the religious motives discovered in Adorno's work.
