Spinoza discovered and studied Descartes's philosophy at the school of Van den Enden and then at the University of Leiden. Spinoza is seen as providing metaphysical views of unparalleled audacity, which remain highly exciting and offer a source of inspiration and a source of theoretical models in a wide variety of fields, including neurobiology. The most general of Spinoza's intentions is to expound in accordance with “the prolix Geometric order” what Descartes had left in a more informal one. Spinoza's original (...) distance from Cartesian conceptions, before becoming obvious in the metaphysical views of the Ethics, is already noticeable in the TIE. In metaphysics, the Spinoza‐Descartes relationship is complex, but cannot be said to take the form of an implicit dialogue or a community of inspiration. Descartes's emphasis on the use of free will, the gap between the two authors in matters of moral anthropology is therefore quite limited. (shrink)
