Amadeo Bordiga (1889-1970) was the founder of the Communist Party of Italy, and was one of the leading voices against the Stalinist hegemony of the 20th century left. Bordiga saw the Soviet Union as "state capitalist," and sought to rebuild a "true" Leninism as the basis for a revolutionary party. The Fundamentals for a Marxist Orientation, and Other Writings on Marxist Theory are the essential pieces of Bordiga's writing that demonstrate his strain of Marxism.

This collection includes:
