A new collection of essays on two of the most important communist philosophers of our time: Alain Badiou and Toni Negri. From the “red years” that followed the social explosion of May ’68 into the first decades of the twenty-first century, Badiou and Negri never abandoned their commitment to a militant politics of equality. Meanwhile, they produced two of the most imposing and consequential bodies of philosophical writing in the communist tradition. Alberto Toscano’s essays tackle multiple dimensions of their work—from ontology to biopolitics, from art to violence, from the theory of capitalism to the challenge of counter-revolution. But all of them are also efforts to explore and answer a single question: What does it mean to be a communist in philosophy?
