Abstract

The proofs of the existence of God in part 4 of Descartes’s Discourse on Method may yet surprise us. These arguments appear to be crafted with such ambiguity that their deeper import has rarely been suspected. This essay proposes that, in spite of the text’s conventional appearance, Descartes exposes the error of scholastic metaphysics, namely, that it mistakes the perfectibility of the human mind for a transcendent perfect being. Superficially, the thinker’s “idea of a more perfect being” serves to ground the traditional theology; but surreptitiously, this idea refers to human possibility and supplies the metaphysical basis for scientific progress, freed from theology altogether. This ironic result is obtained not by speculating on Descartes’s irony directly, but by submitting the “idea of a more perfect being” itself to the Cartesian test of truth and falsehood. In that light, the text’s proofs of God reveal their skeptical, philanthropic intent.
