State Capitalism and World Revolution [PDF ebook] 

60 years ago, CLR James and a small circle of collaborators set forth a revolutionary critique of industrial civilisation. So insular was the political context that the documents of the signal effort never reached public view. Happily, times have changed. Readers have discovered much, even after all these years, to challenge Marxist (or any other) orthodoxy. They will never find a more succinct version of James‘ general conclusions than State Capitalism and World Revolution. In this slim volume, James and his comrades successfully predict the future course of Marxism.
