In this article, I argue that public political theorists need to adopt a different attitude and audience. If they are to help their fellow citizens learn collectively to engage critically with their future to take care of it, they must write and talk not only to their fellow theorists but also to their fellow citizens. To do this, they would need to focus on the opposite of the strictures of their specialised academic discipline that rewards internal debate, arcane language, and abstract theorising. They must provide a clear, persuasive understanding and critique of contemporary social, economic, and political narratives and structures of power. What matters is persuasion, not exclusive expertise; a change of attitude, not method; and a plurality of approaches. Perhaps most importantly, what they teach, write, and say must be comprehensively open to all, not beholden to corporate interests and canons, and they must act as “gadflies” in their society—public critics in battles over ideas, values, and power relations. While history is vital for this future-oriented craft, to bow down before predecessors is to miss the radical imaginative potential of thinking (and teaching) collectively in the present to provide for a better future: to change the world by changing oneself and thus one’s fellow travellers in improving how we live and love together. This would also make public political theory genuinely political.
