Abstract

By interrupting the traditional approach to the distinctiveness of the order of knowledge and the order of nature, and acquiring a unified science, Spinoza changes the customary order of philosophizing and begins his famous book, Ethics, with a treatise on God, nature or substance, a being that, is assumed, first by nature, i.e. in the order of nature, but not first for us, i.e. in the order of knowledge. To accomplish this procedure, Spinoza, on the one hand attributes the extension to the God and on the other hand, chose the geometrical method that implies definitions, axioms and postulates that harmonize with his procedure, to expose his views. In this article, by analyzing Spinoza’s geometrical method, we try to show that how Spinoza achieved his methodological intentions.
