This is the third and final episode in which we discuss transhumanism with authors Tracy Trothen and Calvin Mercer. Calvin teaches at East Carolina University, and Tracy teaches at Queen’s University in Ontario. They’re authors of a fascinating new book called “Religion and the Technological Future.” In this episode, the group discusses some of the most pressing religious implications of transhumanism: should we rethink the nature of immortality in light of technological advances? And what can fiction teach us about all of this?
