... no one is bound to live as another pleases, but is the guardian of his own liberty. - Benedictus de Spinoza

...This divergence and perversion of the essential question is most striking in what goes today by the name of philosophy. There would seem to be only one question for philosophy to resolve: What must I do? Despite being combined with an enormous amount of unnecessary confusion, answers to the question have at any rate been given within the philosophical tradition on the Christian nations. For example, in Kant's Critique of Practical Reason, or in Spinoza, Schopenhauer and specially Rousseau.

As early as the 1670s, and continually, right through the eighteenth century, one finds numerous references in the contemporary controversial literature, theological, philosophical and historical, in all the Western European countries, to ‘Spinoza’ as supposedly the foremost and most dangerous of the ‘atheists’ threatening Christianity, society and the moral order generally, and the ‘sect of Spinozists’ specifically as the veritable hard-core of the libertine underground challenging all the structures of authority then in place.

How then could such a figure, seemingly the least ‘historical’ of philosophers, provide thinkers concerned with transformation, novelty, the event, with the wherewithal to advance radical projects of thought? Why is Spinoza repeatedly be invoked in the most urgent of political and ideological polemics? How could a philosophy turned toward the eternity of being (an ontology) link up with the attempt to understand the collective construction of a common political space and the sometimes catastrophic incursion of worldly events?
