Antonio Negri, a leading scholar on Baruch Spinoza (1632–1677) and his contemporary legacy, offers a straightforward explanation of the philosopher"s elaborate arguments and a persuasive case for his ongoing utility. Responding to a resurgent interest in Spinoza"s thought and its potential application to contemporary global issues, Negri demonstrates the thinker"s special value to politics, philosophy, and a number of related disciplines.

Negri"s work is both a return to and advancement of his initial affirmation of Spinozian thought in The Savage Anomaly. He further defends his understanding of the philosopher as a proto-postmodernist, or a thinker who is just now, with the advent of the postmodern, becoming contemporary. Negri also deeply connects Spinoza"s theories to recent trends in political philosophy, particularly the reengagement with Carl Schmitt"s “political theology," and the history of philosophy, including the argument that Spinoza belongs to a “radical enlightenment." By positioning Spinoza as a contemporary, revolutionary intellectual, Negri addresses and effectively defeats critiques by Derrida, Badiou, and Agamben.
