Spinoza's Ethics is rarely read as a work of political theory. Its formidable geometric structure and its author's commitment to a kind of metaphysical determinism do not seem promising materials from which to fashion a theory of democratic self-government. Yet impressions can mislead. A close reading of the Ethics reveals it to be an impassioned, deeply political book. Its aim is not only to liberate the individualfrom false beliefs and systems of power but also to enable us to act in (...) concert as members of a democratic community. Above all, the work represents a celebration of individuality and the joys of life in all its plenitude. The Ethics provides Spinoza's clearest answer to the question "What is a free people (libera multitudo)? " only briefly alluded to at the end of his unfinished Political Treatise. (shrink)
