Although the world population faces movement, mixing and displacement on a larger scale than ever before, the result has not been a collapse of boundaries but an increase in the rise of new forms of ethnic, cultural and religious identity. Those based in the highly developed countries can extend global influence through wealth and sophisticated technology. This work presents case studies which explore the effect anthropology’s inherited tradition of tolerance and cross-cultural understanding has on the new pursuits of truth. Several chapters focus on the rise of new certainties while others examine notions of diversity providing a critical perspective on the new religious movements and current popular orthodoxies relating to society and culture.
