“A renewal of apocalyptic belief is underway that is unlikely to be confined to familiar sorts of fundamentalism,” John Gray, London School of Economics philosopher, writes in Black Mass: Apocalyptic Religion and the Death of Utopia. “Along with evangelical revivals there is likely to be a profusion of designer religions, mixing science and science fiction, racketeering, and psychobabble, which will spread like internet viruses. Most will be harmless, but doomsday cults . . . may proliferate as ecological crisis deepens.”
