Theology and the Cartesian Doctrine of Freedom, now for the first time available in English, was Étienne Gilson's doctoral thesis and part of a larger project to show the medieval roots of Descartes at a time when the very existence of medieval philosophy was often ignored. Descartes's great intellectual mission in life was not his mathematics but his physics, which was understood as a part of philosophy. We see him navigate the shoals of heated theological and religious strife in his attempt to articulate the metaphysical foundation (and in particular a philosophical vision of God) for his physics or theory of nature. As a layman, he always pleaded ignorance in technically theological matters. He presented himself as a loyal Catholic, quite sincerely in the portrait Gilson paints. This is not Gilson's last work on the development of Descartes' thinking, but the book already shows the engaging, vivid historian of thought who would become world famous. As Gilson guides us through Descartes' voluminous correspondence, the feelers he sends out through his friend Marin Mersenne, his attempts to make peace with the Jesuits, we feel we have lived in seventeenth-century French intellectual circles.
