The chapters herein contained have thrust themselves into my mind as i have read and traveled and thought on existing world conditions. There is a kind of optimism among men that arises out of an eagerness for what they call "progress." In times of peace and supposed prosperity men largely ignore facts as they really exist. We by no means shut our eyes to the good that is in the world, but in this volume we are thinking and writing of the tremendous drift toward evil, and what we believe means a crisis in world history. We confine our observations, however, largely to these United States.
