Alterity or otherness is a central notion in cultural anthropology and philosophy, as well as in other disciplines. While anthropology, with its aim of understanding cultural difference, tends to take otherness as a fact, there have been vigorous attempts in contemporary philosophy, particularly in phenomenology, to answer the fundamental question: What is the Other? This book brings the two approaches to otherness the hermeneutical pragmatics of anthropology, and the radical reflection of philosophy together, with the goal of enriching one through the other. The philosophy of the German phenomenologist Bernhard Waldenfels, up to now little known to anthropologists, has a central position in this undertaking. Waldenfelss concept of a responsivity to the Other offers to cultural anthropology the possibility of a philosophical engagement with the Other that does not contradict the project of making sense of concrete empirical others. The book illustrates the fertility of this new approach to alterity through a broad spectrum of themes, ranging from reflections on theory formation, via discussions of race and human-animal relations, to personal meditations on experiences of alterity.
