The basic challenge to mankind is not population, poverty, war, technology, pollution, religious or racial intolerance, or blind nationalism, but an underlying nihilism promoting violence and frustrating sane policies on these issues.... the only hope lies in the emergence of a potentially worldwide consensus of heart, mind, and will, appealing to all sane men and women everywhere... The time has come for the west to speak to the world in universal terms.... the consensus, if it comes, is likely to surprise by its suddenness, timeliness, and universality.
