“Trotskyism is not a new movement, a new doctrine,” Cannon says, “but the restoration, the revival of genuine Marxism as it was expounded and practiced in the Russian revolution and in the early days of the Communist International.” In twelve talks given in 1942, Cannon recounts a decisive period in efforts to build a proletarian party in the United States. Preface by Jack Barnes, introduction by Joseph Hansen, 8-page and 12 page photo sections, index.
