This is a scholarly book for those versed in the history of socialism, and particularly in the tenets of Marx, Engle and their successors. Here is a re-examination, not only in light of immediate challenge, but over the almost a century that has elapsed since the Marxian theory was promulgated. He proves, by quotation, appraisal and criticism that the present crisis in capitalism is not the one Marx predicted, that most of the tests of his theories have been failures, that the choice lies not between Communism or Fascism on the one side and Democracy on the other, but that there is a third choice. He aims to give adequate representation to statements which correspond to the Marxian theory as well as to those that conflict, and he feels that Marx and Engle grow in stature in contrast to their disciples. He charges today's Marxians with the fact that there is no authority for dictatorship over the proletariat in Marxism. The most interesting part of the book is his study of Browder, and his shifting viewpoint, before and after 1935, and again since the invasion of Finland. He proves, conclusively it seems, that the Communist International takes orders from Moscow. He concludes that we can admire Marx as a rebel, as a champion of the underdog, but not as a philosopher or a practical leader. And he challenges us to muster enough authentic democracy (now lacking) to save us. More value in development than conclusions.
