’Few scholars would be better qualified than Detlef Pollack and his colleagues to undertake such an ambitious project, and we are in their debt. Where others speculate, they investigate. This volume will be essential reading for everyone studying religious change in Europe or any of the individual countries analyzed by the chapter authors.’ David Voas, University of Essex, UK ’Giving insights into religious fields in many countries of the old and the new, enlarged Europe, this collection boasts a consistent, logical, conceptual framework related to discussions of secularization. Highly recommended for anyone interested in religion in Europe and the applicability of theories explaining religious change.’ Irena Borowik, Jagiellonian University, Kraków, Poland 'The publication of this book is of great value. In a sober and nuanced way, and based on solid empirical material, it will function as a valid argument against the dominating trend in sociology of religion during the past twenty to thirty years since it in an excellent way re-establishes secularization theory as the theory with the largest potential to explain changes on the religious field in Europe.'
