Book excerpt: Based on a rigorous construction of theoretical categories and on a close scrutiny of the common challenges confronting Europe and its Turkish neighbour long considered ‘other’ with regard to the accommodation of religious difference, this book sheds light on the possibilities for Europe to find new ways of arranging the relationship between the secular and the religious. As such, it will appeal to scholars of social theory, the sociology of religion, secularisation and religious difference, and social change.
