Hatfield stresses the different aims of Christian and Cartesian meditation (see p. 54), as does Fernand Hallyn, who pronounces the resemblance to religious meditation superficial (Descartes: dissimulation et ironie (Geneva: Droz, 2006), 110–15). See also Ferdinand Alquié, La Découverte métaphysique de l’homme chez Descartes, 6th edn. (Paris: Presses Universitaires de France, 2000 [1950]), 162–4; but also, for a different approach, Peter Dear, ‘Mersenne’s Suggestion: Cartesian Meditation and the Mathematical Model of Knowledge in the Seventeenth Century’, in Roger Ariew and Marjorie Grene (eds.), Descartes and his Contemporaries: Meditations, Objections, and Replies (Chicago and London: University of Chicago, Press, 1995), 44–62.
