The Science and Passion of Communism presents the battles of the brilliant Italian communist Amadeo Bordiga in the revolutionary cycle of the post-WWI period, through his writings against reformism and war, for Soviet power and internationalism, and then against fascism, on one side, Stalinism and the degeneration of the International, on the other. Equally important was his sharp critique of triumphant U.S. capitalism in the post-WWII period, and his original re-presentation of Marxist critique of political economy, which includes the capital-nature and capital-species relationships, and the programme of social transformations for the revolution to come. Without any form of canonization, we can say that Bordiga ́s huge workshop is a veritable goldmine, and anyone who decides to enter it will not be disappointed. He will guide you through a series of instructive, energizing and often highly topical excursions into the near and distant past, into the present that he largely foresaw, and into the future that he sketched with devouring passion.
