Abstract

Spinoza’s geometric method is supposed to pursue crystal-clear argumentation and universal understanding, whereas past philosophers repeatedly claimed that his system failed to comprehend human conditions. If Spinoza’s intention is really to show the way to well-being, his geometric formalization must point to concrete singular existence and conditions. This obvious contradiction comes from the fact that his theory of singularity was yet under construction, while its prototype gives foundation to his Ethics. I reconstruct the theory of singularity that Spinoza conceived but could not finish, which historically precedes but fundamentally differs from Leibniz’s theory of individual concept.
