This landmark volume brings together some of the titans of social movement theory in a grand reassessment of its status. For some time, the field has been divided between a dominant structural approach and a cultural or constructivist tradition. The gaps and misunderstandings between the two sides - as well as the efforts to bridge them - closely parallel those in the social sciences at large. This book aims to further the dialogue between these two distinct approaches to social movements and to show the broader implications for social science as a whole as it struggles with issues including culture, emotion, and agency.
