This is no time for smooth words that hide the true state of affairs, no time for shallow optimism that screens the precipice along whose edge we are walking. Humanity passed through the five-year agony of life-and-death conflict against Nazi attempts at world domination because it earlier hugged the delusion either that the danger did not exist or that it was very slight even if it did exist. It cannot afford to repeat that error. The peril in which it now stands from materialism--whether avowed, open, or disguised, supported by out-of-date science, or molded from out-of-date religion--is just as grave in its own way because of its terrifying spiritual and physical consequences.
