Roberto Esposito, The Faces of the Adversary: The Enigma of Jacob and the Angel – trans. Zakiya Hanati, Polity, February 2026

Roberto Esposito’s poetic and historically layered new book draws on a famous, and famously opaque, passage from the Old Testament to shed light on the vision of self and domination that has profoundly shaped western identity and left its mark on western culture.

These ten lines from Genesis tell the tale of Jacob wrestling with a mysterious adversary on a riverbank. But who exactly is Jacob wrestling with – the divine? Evil personified? Absolute otherness? Or his deepest, most subconscious self, repressed and projected? Who, in other words, is the adversary, and what is the enigmatic conflict that binds the two in perpetual conflict? Interchangeable and yet never resolved, these entwined adversaries speak to our great desire to come face to face with personal truth, even if only for an instant, while coming to terms with its impermanence.

Casting a wide net, Esposito connects his reading of Jacob and the Angel to the fundamental relationship between self and adversary inherited by the modern West and explores the extraordinary influence this story has had on western culture, from philosophy and theology to literature, politics and art.
