This book examines Spinoza’s ontological argument and introduces the concept of "paradoxical singularity." It explores the ways in which Spinoza’s ontology establishes a framework in which singular things are, paradoxically, differentiated through intersecting causes. The book argues that Spinoza’s ontological argument functions at once as a philosophical, religious, and political ethos in which interpretation is inseparable from cooperation. This emphasizes a connection between the productions of knowledge (interpretation) and the way of life (ethos) that those productions involve and express. Recommended for scholars interested in Spinoza’s influence on post-structuralism, trans-individuality, and the history of secular religious thought.
