Tanja Stahler and Alexander Kozin's elegant translation of Bernhard Waldenfels's Phenomenology of the Alien (Grundmotive einer Phanomenologie des Fremden) introduces the English readership to the philosophy of alien-experience, a multifaceted and multidimensional phenomenon that permeates our everyday experiences of the life-world with immediate implications for the ways we conduct our social, political, and ethical affairs.
