How do gods and spirits come to feel vividly real to people — as if they were standing right next to them? Humans tend to see supernatural agents everywhere, as the cognitive science of religion has shown. But it isn’t easy to maintain a sense that there are invisible spirits who care about you. In How God Becomes Real, acclaimed anthropologist and scholar of religion Tanya M. Luhrmann argues that people must work incredibly hard to make gods real. Does this effort help explain the enduring power of faith? Shermer and Luhrmann discuss: the anthropology of religion • what it means when people say they “hear the voice of God” or are “walking with God” • normal “voices within” vs. hallucinations and psychoses • mystical experiences • anomalous psychological experiences • sleep paralysis and other cognitive anomalies • belief in angels and demons • absorption and religious beliefs • prayer vs. meditation vs. mindfulness • sensed presences • why people believe in God • empirical truths, religious truths, mythic truths • how people come to religious belief vs. how they leave religion • theodicy • magic and superstition • witches and witchcraft • shamans and shamanism. Tanya Marie Luhrmann is the Albert Ray Lang Professor at Stanford University, where she teaches anthropology and psychology. Her books include When God Talks Back: Understanding the American Evangelical Relationship with God and How God Becomes Real: Kindling the Presence of Invisible Others. She has written for the New York Times, and her work has been featured in the New Yorker and other magazines. She lives in Stanford, California.
