This timely volume has been produced upon the initiative of the Commission on Social Reconstruction of the Protestant Episcopal Church. In it twelve distinguished Americans seek to apply Christian principles to the various problems inherent in building a better world for all peoples. Eleanor Roosevelt, Frances Perkins, Sumner Welles, and Arthur Compton, each contribute to the volume, as well as such churchmen as Walter Russell Bowie, Edward L. Parsons and Angus Dun, the theologian Reinhold Niebuhr, and the philosopher William Hooking. These men and women deal with the great issues of today: the race problem, full employment, the United Nations, our relations with Russia, our treatment of ex-enemy nations and the moral meaning of the atomic bomb. This is a significant volume not only for church people but for all thoughtful American citizens.
