Walter Truett Anderson considers ideas about the self that have been held by poets and philosophers in the past, and that are held by people in other societies today, and then takes us on a tour of challenges to the modern Western concept of self that are now emerging from various fields of contemporary thought and action - cognitive science, medicine, cyberspace, economics, global politics, spirituality, and more - where assumptions about personal identity are being profoundly reexamined and new ways of experiencing human life are being invented.
