The process of secularization is insufficient if, voided of its original pathos, it leads to any form of sacralization of the immanence. Secularism becomes insufficient, if not harmful, in the same way as religious fundamentalism, if it becomes an obstacle to building pluralistic coexistence. Therefore, secularism should acknowledge the emergence of religious challenges. Religion has found, in the crisis of reason (metaphysical, scientific, and political), an opportunity not only to be present in the public sphere, but also to demand the right to equal treatment—appealing to the same democratic principles of secularism—and the right to political participation. Secularism cannot respond to these challenges with another form of “enlightened fundamentalism.”
