This book argues that neither theories of secularisation nor theories of lived religion offer satisfactory accounts of religion and social change. Drawing from Deleuze and Gauttari's idea of the assemblage, Paul-Francois Tremlett outlines an alternative. Informed by classical and contemporary theories of religion as well as empirical case studies and ethnography conducted in Manila and London, this book re-frames religion as spatially organised flows. Foregrounding the agency of hon-human actors, it offers a compelling and original account of religion and social change.
