This article focuses on two different styles of profanation in Spinoza and Badiou. Notwithstanding the significant differences between them, their shared desire for profanation testifies to an interesting convergence. I deal with this convergence in divergence as a case of disjunctive synthesis through a comparison of the different understandings of religion in Spinoza and Badiou’s truth procedures. It is commonly held that Spinoza operates with three understandings of religion. But I argue that Spinoza’s thought opens up the space for a (...) fourth understanding of ‘religion’. Then I discuss the formal similarity between Spinoza’s four religions and Badiou’s four truth procedures. I illustrate this discussion through two diagrams. I claim that Badiou’s truth procedures could be perceived as the Spinozist diagram’s re-entry into itself. (shrink)
