Abstract
In the present paper we propose to approach the Spinoza`s methodological project from a philosophical and historical perspective broad enough to adequately understand the reasons that led him to adopt geometric method to expose his philosophy. Even if the topic has been widely discussed by Spinoza´s commentators in the four centuries since the Ethics was published, we believe that the approaches are either inadequate or suffer from some fragmentation, in the sense that they address this or that aspect, but don`t put together all pieces that make up the puzzle. Likewise, we consider that a full understanding of such application of geometric method transcends the mere question of whether it was successful or not in terms of logical rigor. So that, the fundamental task in the present work is unite various aspects that help us understand Spinoza`s methodological choice in a synoptic vision, in which both historical and systematic aspects can be included. To this end, we start from a hypothesis which allow us glimpse a certain unity behind the reasons that lead Spinoza to choose the geometric method, namely: our philosopher tries to reach an ideal of science, which combines some conceptual elements of Aristotelian tradition with others from Cartesian philosophy.
