Is the resurgence of religion in our millennial moment a case of zombies or of vampires? are we dealing, that is, with an atavistic army of stumbling, mumbling idiots, or are we encountering a phenomenon with teeth: vital, adaptive, crazy-beautiful, and ready to take some revamped general education courses at Harvard? I think we can conclude from these essays that we are dealing with vampires. In other words, like today's teenage vampires, the reanimated religions on the contemporary world stage are not anomalous, exceptional, or archaic. Instead, globalization, by draining functionality and glamour from the nation-state, has summoned organized religions and postreligions to take on ever-more-powerful political roles. Hence the brazen entry of an array of latter-day saints into the sempiternal sunlight cast by the restless streaming of information, capital, and populations across planetary time zones, from jihadist organizers and evangelical Alaskans to Harry Potter activists and irate Apple users.
