With her unfailing genius for bringing issues into sharp relief, Barbara Ward highlights the great challenge the rich nations today. Among all the revolutions that have changed ideas she spots four as paramount the revolution, of quality, the a material here and now, the biological revolution, and the application of and capital to the economic progress of nations. These with the rich nations have been achieved, with the emerging nations. To be sure through colonial suzerainty they have been given some though inadequate tools, but through these same overlords they have come to the revolutionary factors with freedom, only to find a great gap. Communism ready to offer them achievement in recognizable time. As she analyses the Communist blueprint and the harsh discipline exacted to secure their goals, she acknowledges the attraction for the emergent nations. Here it has been done. The Western nations have hardly began to emerge from to formulate decisions to combat this peril. She pinpoints the seemingly insuperable difficulties, the deterrents to production when material incentives seem inadequate, population growths exceeding production growths, education for only the few, no acceptance of the need to save in order to build capital. What are the polities of developments. The colonial powers left a residue of problems to be overcome. Certain steps must be taken before it is too late- these she charts. An important book in the realm of ideas.
