Hannah Arendt's Rachel Varnhagen: The Life of a Jewess is the biography of Varnhagen that simultaneously attempts to define Rahel Varnhagen's gender and national identity as a resident in early 19th century Germany in Varnhagen's own terms, while Arendt refines her political theory. Rachel Varnhagen is portrayed throughout the book as a complex character; a Jewish woman in a German society at the dawn and immediate following years of the Napoleonic Revolution. Arendt is an accomplished political-philosopher who despised being called a philosopher. Arendt's rise to academic prominence came when she wrote Eichmann in Jerusalem; Eichmann was where she coined the phrase "banality of evil" in reference to the famous trial of the Nazi Adolph Eichmann. Arendt was on assignment in Jerusalem for the Eichmann trial as a reporter for Harper's because she could not attain a university teaching position. Arendt had not successfully completed the monograph that was to be her Ph.D. dissertation. During the National Socialist ascension to power in 1933 Arendt was forced into exile, therefore hindering the completion of the biography of Varnhagen and her doctoral dissertation.

Arendt studied under Karl Jaspers and Martin Heidegger the later of which she had an affair. She is most known in political philosophy circles for her study of totalitarian regimes in Origins of Totalitarianism. Arendt collected the published and unpublished letters of the famous salon, bourgeoisie-oriented Varnhagen to map Varnhagen's identity through the inner voice she reveals in her letters. Through reading the letters it is evident that Varnhagen is practically apolitical, but she struggles with her German-Jewish identity and her life as a woman. Arendt explores the complexities of this dynamic through attempting to slip into Varnhagen and convey to the reader Varnhagen's existence. While in the process of amalgamating the various stories of Varnhagen, Arendt also devises her political theory.

Varhagen was at the center of an aristocratic salon where literature and culture were often discussed and she was viewed as a Jewish exception to anti-Semitism. It was believed at the beginning of the nineteenth century that all anti-Semites had their exceptional Jew, and for the many attendees of Varnhagen's salon it was Rahel. In adding her political theory into the construction of Varnhagen's biography Arendt spares Varnhagen no sympathy, often thinking that these very exceptions furthered the anti-Semitic cause.

In essence what Arendt has done is constructed a philosophical-psychological biography delving into the subject's mind, breaking the barrier between subject and observer by using the letters as a background to reconstruct the thoughts of Varnhagen. Varnhagen wrote her letters as a narrative, waiting and watching for life to unfold, unwilling to participate in introspection. Fearing that contemplation of the past might lead to her rejecting her identity and denial of her self-asserted uniqueness.

Varnhagen befriended many of the most prominent novelists and poets; her salon suggested a milieu of sophistication. However, Varnhagen's letters allowed Arendt intense introspection on the feeling of being a Jew in a largely anti-Semitic culture and being a woman in a misogynist culture. Arendt's political theory is never more evident then when she wears the skin of Varnhagen and talks about the Jewish question. Arendt believes that the common Jew attempted to escape their Jewishness (Varnhagen was baptized) only to allow other Jews to flounder in their Jewishness; each individual sought to break from the community at the cost of leaving the others to be victims of virulent anti-Semitism. Arendt is at her sharpest when she philosophizes on the impact of the Napoleonic Revolution on Jews, "it would be incomparably more difficult to escape from a reformed Judaism than from orthodox Judaism; that association for the assimilation of the Jews could lead ultimately to nothing but the preservation of Judaism in a form more suited to the times (179)."

In the preface to the book Arendt says, "It was never my intention to write a book about Rahel; about her personality, which might lend itself to various interpretations according to the psychological standards and categories that the author introduces from outside; nor about her position in Romanticism and the effect of the Goethe culture in Berlin, of which she was actually the originator; nor about the significance of her salon for the social history of the period; nor about her ideas and her "weltanschauung," in so far as these can be constructed from her letters. What interests me solely was to narrate the story of Rahel's life as she herself might have told it. (81)

Rahel believed she let life happen to her and simply observed and recorded her situations. She was, "letting life rain upon her." She was an prophetic individual that simply aspired to convey what happened to her as destiny. But in this role as intermediary recorder of the past she observed and her unknown, but unconscionable future destiny she thought she was an exception; one that must succumb to destiny, but not attempt to influence it. An individual that was so shortsighted that she failed to consider the fact that the destiny that awaited her, the history that was being revealed and shaped her life was less important than her own life. She was romanticized by contemplation of the past and its unraveling into the future of which she only thought she was a part. Varnhagen was a paradox; waiting like everyone else for history and life to happen but yet she continued to assert her uniqueness. Varnhagen attempts to solve the paradox by waiting for history to unveil, but not discover who she was-only what she could be. In the physical world Varnhagen could not deny her Jewishness, but she aspired to be malleable, devoid of shape and identity, traveling on the waves of history as they splashed on the shores of her continuously unfolding destiny. Arendt best summarizes Varnhagen by saying, "she wished to stand outside reality, to merely take pleasure in the real, to provide the soil for the history and the destinies of many people without having any ground of her own to stand on (145)."
