In this important book, Antonio Negri develops the key ideas thatwere to form the basis for the highly influential analyses of newforms of power and social struggle presented in Empire andMultitude. He shows how new technology and the break-up of thetraditional factory have created new social subjects whose value isno longer tied to their skill. The spread of communication networksand the globalization of production mean that capitalism has becometotalized ? but not, Negri stresses, monolithic. On thecontrary, the possibilities for subversion have correspondinglyincreased. Going beyond classical Marxism, he shows how old solidaritiesmust be reformulated and new alliances created. The struggles whichmarked the political end of the twentieth century are now beingrepeated in a new historical conjuncture, giving rise to new formsof transnational solidarity that can challenge dominant globalpowers. This new paperback edition, which includes a new Preface by theauthor, is an excellent introduction to the work of one of the mostinfluential political thinkers writing today and will be essentialreading for anyone who wishes to understand the new forms ofconflict and struggle that will shape the world in the twenty-firstcentury.
