When Sigmund Freud published his theory of the unconscious, in 1899, he popularized an idea that had fascinated generations of Jewish philosophers before him. In this book, Clemence Boulouque charts the development of the pre-Freudian unconscious from subcultural inquiry to dominant discourse during the long nineteenth century. Although Freud’s scientific notion differed from Schelling’s mythical description of the abyss from which creation springs, its resonance with older ideas was celebrated as an opportunity to express specifically Jewish contributions to modernity. Indeed, Boulouque shows that the pre-Freudian unconscious emerged from conversations in Jewish mysticism about otherness and coexistence. In the hopeful years before World War I, Boulouque argues, such reflections offered the possibility of emancipation not only to Jews but to all.
