Secularization in Europe: Causes, Consequences, and Cultural Diversity

Abstract

This paper explores the timeliness and relevance of secularization theories in Europe. It seeks to understand how the classical theories of secularization—rationalization, societalization, functional differentiation, and existential security—and their theoretical innovations—namely, cultural diversity—help describe religious phenomena in a specific set of European countries—Austria, Italy, Poland, Portugal, Slovakia, and Spain. In this context, cultural diversity shows the strongest negative correlation with religiosity. These findings arise from the correlation between the different theories of secularization, the independent variables, and an index of religiosity, the dependent variable. Cultural diversity, as a good predictor to explain secularization in Europe, shows how contact with different religious and non-religious worldviews enhances a mutual fragilization that can lead individuals from uncertainty to the rejection of religious beliefs.
