In this article the author constructs a typology of the different senses secularization has been understood, and how these various senses correlate to different models of secularization in the modern world. He engages with the works of Jürgen Habermas and argues that Habermas’s conception of secularization is too closely linked to the European model in which secularization and modernization are correlated. Casanova argues that the world may be becoming “post‑secular,” characterized by the re‑emergence of religion as a public issue in some societies.
