Since the dawn of civilization there has been a disparity between Man’s technological progression and his social performance. The advance of technology, particularly the most recent advances during the two centuries 1773 – 1973, has vastly increased Man’s wealth and power, and the “ morality gap” between Man’s physical power for doing evil and his spiritual capacity for coping with this power has yawned as wide open as the mythical jaws of Hell. During the last 5,000 years, the widening ‘ morality gap’ has caused mankind to inflict on itself grievous disasters.
