This book begins by noting a crisis in Marxism and the insight that the only vital Marxism left has a fragmentary and radically-revisionist character. The author advances the idea that dialectic ought to be completely open, understood exclusively heuristically, as well as unencumbered by progressivist and synthetic frameworks. Among else, the book deals with issues of closed dialectics, the Bolshevization of Marxism, real socialism, and the ideology of liberal democracy.
