Our lives are populated by rituals. Baptisms. Funerals. Graduations. Singing happy birthday, chanting cheers at a sports event, saying grace before dinner. When we perform rituals, there's no causal link between the behavior and the hoped for effect; for example, there's no causal connection between exchanging rings at an altar and becoming wedded to another human being.
But my guest would say that doesn't mean that rituals are useless and irrational; in fact, doing two decades of research on rituals caused him to do a one-eighty on his perception of their value. His name is Dimitris Xygalatas and he's an anthropologist and the author of Ritual: How Seemingly Senseless Acts Make Life Worth Living.
