"Spinoza's thought is completely idealistic when it is presented as negative thought, when it develops the bourgeois utopia, living it in the extreme, abstract consequences of its spiritual idyll; it is, in contrast, completely materialistic as soon as it is reassembled in a constructive way, inverting the impossibility of an ideal world in the materialistic tension of its components and embracing these in a practical project, in a violent dynamism of worldly liberation. "Benedictus maledictus": never has a philosopher been more rightly hated by his times, a bourgeois and capitalist epoch."
