: In his Theological Political Treatise Spinoza lays the groundwork for the secular project of separation between religion and public life which will be characteristic of Western politics throughout Modern and Contemporary Ages. This project, however, is marked by a number of tensions which can already be seen in Spinoza’s work. This article tries to delineate the philosopher’s argument, identify and make explicit its main concepts and point to some of the tensions still working within the secular project, tensions which (...) arise from the philosophical reasoning employed by this project since its inception, as can be seen in Spinoza’s work. Keywords: Spinoza; Theological Political Treatise; secularism; freedom; religion; politics. (shrink)
