Paul-François Tremlett offers a treasure trove of concepts and methods to describe how social worlds change in relation to the category of religion. His is an inspiring, kaleidoscopic presentation of contemporary theory that draws on ideas about secularization, biology, economics, politics, post-humanism, assemblages, bricolage, music and original artwork to expand and enrich the vision and interdisciplinary toolkit of scholars and students of politics, religious studies, sociology and intellectual history.
