In the context of the philosophical issues addressed by this panel, we would like to propose a reflection on a thinker considered an anomaly in Western philosophical tradition. Spinoza is known not only for his rejection of divine transcendence and Cartesian dualism, but also for denouncing as illusory the idea of freedom based on a sovereign will to self-determination. Moreover, Spinozism has often been compared to certain features of Eastern Taoist thought. This makes it all the more interesting to return to consider the peculiar cosmology that Spinoza could only sketch out in his texts. Spinoza's conception of a nature devoid of substances forces him to develop a non-anthropocentric view of the universe, in which not only its centre is nowhere and its circumference everywhere, but where every individual, from the simplest to the most complex, is only a mode of the unique substance immanent in all its manifestations. Starting from some considerations of his physics, we would like to show the great interest that Spinoza's thought can still represent today, especially in light of the latest hypotheses in the field of cosmology.
