The media has temporarily turned its large but constantly blinking eye away from cult-of-the-day reportage after the Waco conflagration, but such organizations continue to collect adherents. Martin Gardner, best known as mathematical-games-meister for Scientific American, turns his refreshingly unblinking gaze on the origin and continuing growth of the Urantian cult. It is a marvellous study of the ways in which ideas can be propagated through society.
