Was Descartes an Individualist? A Critical Discussion of W. Ferraiolo's "Individualism and Descartes"

In his paper "Individualism and Descartes," William Ferraiolo puts into question the widely accepted interpretation of Descartes as an individualist about mental content. In this paper, I intend to defend this interpretation of Descartes's thinking against Ferraiolo's objections. I shall hold, firstly, that attributing to Descartes an individualist doctrine is not historically misguided. Secondly, I will try to show that Descartes's endorsement of anti-individualism would lead either to depriving sceptical hypotheses of their force or to rejecting the epistemological privilege of the first person. And, thirdly, I shall try to show that Ferraiolo's objections to the individualistic interpretation rest on two important errors: a misapprehension of the argumentative order of the Mediations and a confusion between the notions of causal and constitutive dependence of content on the external environment.
