" A second normal feature of religion is ritual, which was actually religion’s cradle, for anthropologists tell us that people danced out their religion before they thought it out. Religion arose out of celebration and its opposite, bereavement, both of which cry out for collective expression. When we are crushed by loss or when we are exuberant, we want not only to be with people; we want to interact with them in ways that make the interactions more than the sum of their parts—this relieves our isolation.
