Religione e razionalità comunicativa. Juergen Habermas e la " Nuova Teologia Politica"

Jürgen Habermas’ recent work is focused on the relationship between reason and faith in what he suggestthat we should name post-secular society. Habermas argues that traditional religions such as Christianity canhave semantic contents very useful to uphold a moral motivation in order to contrast the instrumental reasonof the globalized markets. I will try to show that these recent developments of Habermas’ theories risk toconflict with some elements of his previous approach. As a consequence, I suggest that we carefully look tothe critiques that the catholic theologian J. B. Metz made to Habermas’ previous approach. In fact, I arguethat Metz’s proposal of a “New Political Theology”, which is characterized by the concept of anamnesticreason, shows how to overcome, or complete, some limits of the first formulation of the theory of communicativerationality. Nevertheless, Habermas’ recent openness on these topics, even if problematic with hisprevious approach, stimulates to rethink on the relationship between reason and faith, religion and democracy.
