In this essay, I offer an interpretation of Arendt’s biography of the Jewish-German salonnière, Rahel Varnhagen: The Life of a Jewess. Treating the book as a work of political theory, I develop two arguments: First, I contend that Arendt’s study lays the grounds for a political epistemology of marginality and exclusion, making her a standpoint theorist avant la lettre. Second, I argue that Arendt’s book gives us an account of the process of ‘becoming political.’ This helps complement, and to a (...) degree counter, her insistence in more widely read books that political freedom is an exclusively plural experience in the public realm. This insistence sidelines the role played by individual political consciousness in the decision to engage in action, as well as the necessary interaction between the private and the public spheres in becoming a political subject. Arendt’s biography suggests that becoming political can be facilitated by a solidary, and private encounter with the excluded other. (shrink)
