In Eric Santner puts Sigmund Freud in dialogue with his contemporary Franz Rosenzweig in the service of reimagining ethical and political life. By exploring the theological dimensions of Freud's writings and revealing unexpected psychoanalytic implications in the religious philosophy of Rosenzweig's masterwork, Santner makes an original argument for understanding religions of revelation in therapeutic terms, and offers a penetrating look at how this understanding suggests fruitful ways of reconceiving political community. Santner's crucial innovation in this new study is to bring the theological notion of revelation into a broadly psychoanalytic field, where it can be understood as a force that opens the self to everyday life and encourages accountability within the larger world. Revelation itself becomes redefined as an openness toward what is singular, enigmatic, even uncanny about the Other, whether neighbor or stranger, thereby linking a theory of drives and desire to a critical account of sociality. Santner illuminates what it means to be genuinely open to another human being or culture and to share and take responsibility for one's implication in the dilemmas of difference. By bringing Freud and Rosenzweig together, Santner not only clarifies in new and surprising ways the profound connections between psychoanalysis and the Judeo-Christian tradition, he makes the resources of both available to contemporary efforts to rethink concepts of community and cross-cultural communication.
