"In April 2003, after twenty-four years spent in conditions of imprisonment, exile, and constraint, Negri was finally granted a passport. This gave him the opportunity to travel worldwide and to test the political theory which had given rise to his bestselling volume Empire, co-authored with Michael Hardt. This new book, Empire and Beyond, brings together texts in which Negri explores and elaborates the revolutionary ideas that underpin his social and political theory. He examines, among other things, the political movements that are emerging today to challenge and resist the power of Empire; the hegemony of immaterial labour; and the subjective and objective conditions of social transformation in our contemporary postmodern world. Each of these texts, delivered as speeches to audiences around the world, gives Negri the opportunity to test his ideas with politically committed audiences with a view to developing theory further -- a continuous and exciting process of critique and renewal." -- back cover.
