This text paints a picture of conversion far more complex than its customary image in anthropology and religious studies. Conversion is very seldom simply a sudden moment of insight or inspiration, it is a change both of individual consciousness and of social belonging, of mental attitude and of physical experience, whose unfolding depends both on its cultural setting and on the distinct individuals who undergo it. The book explores religious conversion in a variety of cultural settings and considers how anthropological approaches can help us understand the phenomenon. Fourteen case studies span historical and geographical contexts, including the contemporary United States, modern and medieval Europe, and non-western societies in South Asia, Melanesia and South America. They discuss conversion to Christianity, Judaism, Hinduism, Islam and Spiritualism. Combining ethnographic description with theoretical analysis, the authors consider the nature and meaning of conversion, its social and political dimensions and its relationship to individual religious experience.
