In the Chinese Revolution of 1925-27 the Communist International played a very great role, depicted in this book quite comprehensively. We would, however, seek in vain in the library of the Communist International for a single book which attempts in any way to give a rounded picture of the Chinese Revolution. Instead, we find scores of "conjunctural" works' which docilely reflect each zigzag in the politics of the Communist International, or, more correctly, of Soviet diplomacy in China, and subordinating to each zigzag facts as well as general treatment. In contrast to this literature, which cannot arouse anything but mental revulsion, Isaacs' book represents a scientific work from beginning to end. It is based on a conscientious study of a vast number of original sources and supplementary material. Isaacs spent more than three years on this work. It should be added that he had previously passed about five years in China as a journalist and observer of Chinese life. The author of this book approaches the revolution as a revolutionist, and he sees no reason for concealing it.
