In face of the numbers of people who are suffering anxiety attacks over AIDS, global warming, ozone sharp decline, and the proliferation of chemical weapons, you have a disturbingly large population easily influenced by the madness aroused with the arrival of the period of the second thousand years.Even supposedly sober observers are taking positions in the millenarian parade. Novelist, poet, and science writer Brad Leithauser is convinced the second millennium is going to bring a "psychological shift" that will "literally redefine what it means to be a human being."Leithauser believes that global weather patterns will undergo random, even chaotic, changes produced by the dreaded greenhouse effect. In his novel Hence set around 2000, Leithauser visualizes religious leaders seizing on the resultant disturbances -flooded cities, soaring cancer rates, and what have you -and taking them as a sign that the end is near.At the same time, Leithauser thinks, a combination of high-speed living and runaway technology will serve further to alienate people from themselves. He predicts that invasive media will bring an inescapable large number of stimuli. In this atmosphere of "evershortening collective memory," books will become pass. Indeed, any form of reflective solitude will become "quietly sinful," says a character in Leithauser’s novel, and seeking it out will require "almost an act of social defiance."Economic expert Ravi Bartra is equally convinced that by the dawn of the second millennium people will have undergone a thorough spiritual and economic transformation. He warns that the voices of the rich will soon superheat the global economy to the point of explosion and collapse, in the wake of which "society will border on chaos. There will be a polarization of society into two classes -the haves and the have-nots -and there will be a lot of crime and street demonstrations" as the angry have-nots make strong claim for food, shelter, and social justice.But Batra, unlike Leithauser, sees the coming bimillennial breakdown as a sort of getting rid of sin by fire on the way to a better world. From the ashes of economic and social collapse, he says, will rise a "higher consciousness"--a climate in which pornography, selfishness, and extreme concentration of wealth are reproached and society becomes "more concerned with the handicapped and the weaker." On the job, he foresees "far more democratic large factories, where employees not only sit on boards of directors but actually run companies." Meanwhile, discipline will capture the home-and-family front, with "children obeying their parents more, and more family stability, fewer divorces.\ The first two paragraphs say that, faced with the various problems, people are likely to become crazy about().
