Goodwin and Jasper's criticisms of various iterations of political process theory ape incorrectly applied to the entire developing paradigm. Their indictment offers a rigid and narrow representation of the theory and rejects the social science enterprise of building theory altogether. At the same time, their criticisms raise important puzzles for scholars working on social movements, particularly about defining opportunities, and studying culture. I answer their criticisms of the theory, acknowledge useful questions and challenges that they offer, and conclude by suggesting an agenda for research on social movements in the future.
