Roberto Esposito brings together the voices of modern culture to explore what it means to confront the Other and, ultimately, oneself. At the heart of the Old Testament is a brief and enigmatic scene that permeates Western tradition and continues to this day: the nighttime struggle of the patriarch Jacob with an undefined being on the banks of the Jabbok River. Was it an angel, a god, an enemy, his own reflection? Was it truly a struggle or perhaps a dance, an encounter with the most intimate and unknown part of himself? Theologians, philosophers, artists, and psychoanalysts have attempted to decipher the mystery without ever succeeding. In this essay, Roberto Esposito does not seek a definitive answer, but rather opens up the horizon of questions. He brings together the voices of modern culture to explore what it means to confront the Other and, ultimately, oneself. Jacob's struggle radically questions our identity, its conflicts, and its wounds.
