The anthropologist no longer compares marriage customs from all over the world as they come to hand. He realizes that marriage is likely to be a different rite as it is practiced respectively among peoples, with and without civil government, or among nations that have come under the influence of a world religion or remain in a status of tribal ceremony. The whole culture of the group must be more or less known before the history and meaning of an institution can become intelligible. Detached from its culture mass, a custom reveals as little of its functioning as an organ dissected out of the living body.
