In the wake of various secularization processes, a growing number of people in Western societies are now describing themselves as "non-religious." But what does this sociological fact really mean, for the Church and for society at large? Has human religiosity a future after secularization? It does, this book argues, but in a radically altered form. Taking its cue from Pope Francis's suggestion that globalizing humanity is presently living through a genuine "epochal shift," this book presents an original analysis of the transformative effect of secularization on our spiritual predicament in the Western, now definitively post-Christian, world. Instead of succumbing to the all-too-common polarizations in contemporary religious discourse, this book aspires to overcome the "religious" vs. "secular" dichotomy through developing the logic of "Radical Secularization," arguably the genuine novelty of the particularly Western process of secularization. The past homogeneously religious culture is certainly dusking, but this only paves the way for the dawn of the future and radically open horizon for our human search for meaning. This challenging book will offer intellectual impulses and spiritual incentives to everybody who ponders the future of human religious evolution after secularization.
