Here, Andy Blunden presents the first of two volumes on how Marx used Hegel's Logic in his Capital. In this first volume, Blunden reviews the current literature on the topic with detailed reviews of the contribution of 10 authors, representing the spectrum of approaches. Finding that present-day writers fail to understand the Logic and misrepresent Capital as a work of Logic, Blunden focuses on the passage in the Logic entitled "The Idea of the True," which is ignored by every writer in the present-day debate.
