Reforming the Art of Living seeks to rectify this rather common oversight in two ways. First, it aims to elucidate the nature of Descartes’s account of virtuous belief formation. Second, it aims both (i) to illuminate the social significance of Descartes’s philosophical program as it relates to the understanding and practice not of science, but of religion and (ii) to develop a kind of Leibnizian critique of this aspect of his program. More specifically, it aims to show that Descartes’s project is “dangerous,” insofar as it is subversive not only of traditional Christianity but also of other traditional forms of religion, both in theory and in practice.
