Abstract
The main aim of this paper is to revive interest among philosophers, and particularly philosophers of religion, in Descartes’ Fourth Meditation. Two recent works on Descartes1 make virtually no mention of it, and this omission seems to reflect a fairly general feeling that it is of relatively little philosophical significance. In philosophy of religion textbooks, the Fifth Meditation is often discussed in connection with the ontological proof, but in sections devoted to the problem of evil, no reference is made to the Fourth. Even in John Hick’s admirable study of the problem,2 Descartes’ contribution is relegated to a single sentence in a single footnote.
