In Spinoza, what I call the ‘Being Individual Multiple’ is the multitudo. Its form of life is Democracy, understood as the autonomous and conflictual organization of collective dynamics and not one form of government among others. Combining an original mode of argumentation with a critical discussion of opposing interpretations, I maintain that democracy is the translation into politics of the third and highest kind of knowledge in Spinoza, intuitive science. I argue moreover that the multitudo self-organized in a democracy has (...) the capacity to experiment and express a different rationality with respect to the singular individual. Wisdom and democracy thus converge to give life to something unknown and original in western political modernity. (shrink)
