"To see so many friends bringing such critical contributions to bear on my work serves as a spur to action once again." Antonio Negri The spectacular success of Empire and Multitude has brought Negri's writing to a new, wider audience. Negri's work is singular in its depth and expression. It can be difficult to grasp the complexity of his ideas, as they are rooted in the history of philosophy. This book offers an introduction to his thinking, and is ideal for readers who want to get to grips with his key themes. Outstanding contributors include Pierre Macherey, Charles Wolfe, Alex Callinicos, Miguel Vatter, Jason Read, Alberto Toscano, Mamut Mutman, Ted Stolze and Judith Revel. Written with dynamism and originality, the book will appeal to anyone interested in the evolution of Negri's thought, and especially to students of political philosophy, international studies and literary theory. This book is the sequel to The Philosophy of Antonio Negri, Volume One: Resistance in Practice (Pluto, 2005) but can be read entirely independently.
