One of the rising stars of contemporary critical theory, Bruno Bosteels discusses the new currents of thought generated by figures such as Alain Badiou, Jacques Ranci�re and Slavoj Zizek, who are spearheading the revival of interest in Communism. Bosteels examines this resurgence of Communist thought through the prism of "speculative leftism" - an incapacity to move beyond lofty abstractions and thoroughly rethink the categories of masses, classes and state. Debating those questions with writers including Roberto Esposito and Alberto Moreiras, Bosteels also provides a vital account of the work of the Bolivian Vice President and thinker �lvaro Garc�a Linera.
