The two key essays by Antonio Negri brought together here were written in prison two decades apart. "Time for Revolution" illuminates the course of Negri's thinking from the 1980s to Empire and beyond. It reflects Negri's abiding interest in the philosophy of time and resistance. The first essay is a central work in Negri's oeuvre, tracing the fracture lines which force capitalist society into perpetual crisis. The second essay, written immediately after "Empire", provides a conceptual toolbox, deepening our understanding of the two key concepts of empire and multitude. "Time for Revolution" explores the issue of our times: is there still a place for resistance in a society utterly subsumed by capitalism?
