The theory of secularization was the hermeneutical paradigm of the process in which modern western societies witnessed the eclipse of religion in public life. In recent years, a significant amount of literature in the Social Sciences has been warning of the crisis of this paradigm and the need to revise it. In this context, the notion of post-secularity appears as a likely candidate to become the new paradigm of the tensions between religion and the secular in today’s world, with the promise of building bridges between religious rationality and secular rationality.
