In Part I, Kurtz takes us on a tour of the chief religious and moral philosophies available to Western man at this time. He gives detailed critiques of Christian theism and of Marxism. He shows how the original humanism of Marx has been betrayed in the Communist nations. In Part II, Kurtz brilliantly develops a positive viewpoint, a dynamic presentation of the elements of the good life in which we may realise the human potential and the fullness of being . In Part III, the author provides an arresting exposition of international problems and their intelligent solution. He stresses the global consciousness of the humanist outlook and its allegiance to all humanity, and demonstrates how the methods of reason can be applied in our personal lives and in world affairs.
