This book is about the making and unmaking of socio-cultural differences, seen from anthropological, sociological and philosophical perspectives. Some contributions are of a theoretical nature, such as when the "problem of translation", "the enigma of alienity" or "queer theory" are addressed; other contributors throw light on contemporary issues like the integration of Muslims in Norway, identity-forming processes in "Creole" societies or "neo-traditionalist movements" and "identity" in Africa. Moreover, the book deals with "strangers" looked at from an "anthropology of the night". Special emphasis is placed on how globalization and the rapid spread of ever new technologies of information have generated ever new patterns of inclusion and exclusion, and how these can be theorized.
