For much of European Christian history, asceticism has been associated with the capacity to transform individuals as well as societies. As an organised collaborative exercise in monasteries, asceticism enabled monks not only to live a life preparing for eternal life but also to generate ground-breaking technical and social innovations. Drawing on identity theories and recent developments in the social movement literature, we examine how asceticism has been the impetus for various individual and societal transformations and explore whether asceticism can still (...) unfold such transformative power. In particular, we discuss whether and how ongoing movements for Voluntary Simplicity (VS) and further reflections on that, as found, for example, in the work of the sociologist Ulrich Beck, might assist humans in coping with climate change. Our article contributes to recent environmental ethics research by exploring the role of asceticism in potentially triggering collective climate action and its contribution to helping individuals to live meaningful lives in the face of climate change.
