Galbraith returned to add the weight of some four hundred pages of his wit and learning to the already fashionable convergence theory. Just now it is the fashion among many political scientists, sociologists, sovietologists, and economists to speak of convergence when they write about the Soviet Union or discuss relations between the Russian government and the American. The Russian armies fought valiantly as they suffered the brunt of German attack and invasion, which gave us a sense of moral debt, a feeling that was promptly put to use by Stalin and his apologists to obscure the moral issues of the peace. A more sophisticated theory came from the Russian intellectuals who had been exiled or had fled from Russia in the twenties and become important writers and teachers in sociology or political science in the United States, always retaining a deep emotional attachment to the land of their birth, such men, for instance, as N. S. Timashev and Pitirim Sorokin.
