The chapter explores the rich resonances of Bergson’s philosophy in the field of politics and political thought, demonstrating how Bergson’s later thought provides crucial insights for contemporary problems and debates. It shows how Bergson takes up a Rousseauian strand of political theory that exploits the productive inconsistencies of the republican tradition and situates him within a realist tradition going back to early Christianity (with Pascal as his central reference) that resonates with current realist conceptions of the political. The chapter then moves to consider ways in which Bergson’s conceptions speak to - and disrupt - debates concerning nationalism and cosmopolitanism in political theory today, and in particular, debates between partialists, cosmopolitans, and dualists. Highlighting Bergson’s own participation in politics, the chapter then discusses Bergson’s contribution to the thinking of human rights via one of his early readers, the Canadian diplomat John Humphrey, whose notion of process serves as the motif of the essay’s concluding critical assessment of Bergson’s notion of democracy as a work in progress.
