How can political theory respond to the challenges of mass action in the Anthropocene? In this article, I review criticisms of the recent work of William Connolly and respond by way of a particular mode of theory revision that can be found in Connolly’s work of the last 15 years. I argue that Connolly’s recent work marks a strategic turn in his thought, emphasizing the relationship between revisions to theory and practical experimentation in politics. In the second section, I illustrate (...) this relationship by revising Connolly’s notion of the ‘climate general strike’ in light of failures of climate strikes in recent years. Rosa Luxemburg’s theory of mass strikes guides the revisions advanced in this section. In the third section, I move up a level of abstraction to think through how this suggested revision to climate strike strategy can feed into alterations and clarifications of key concepts in Connolly’s political theory.
