Abstract

“Locating the Lost Island” replies to Lynne Rudder Baker and Gareth B. Matthews’s “Anselm’s Argument Reconsidered,” in which the authors claim to have produced a sound version of Anselm’s ontological argument. Using Gaunilo’s “lost island” counterexample, this chapter explores the question whether Anselm’s argument can prove the existence of the greatest conceivable being without also “proving” the existence of the greatest conceivable island. Baker and Matthews argue that for any conceivable island, a greater island is conceivable, but that there cannot be a conceivable being greater than the greatest conceivable being. Their strategy is vulnerable on two counts. It does not address the possibility that there is no upper limit to greatness in conceivable beings. Nor does it assure us that the greatest conceivable being is even logically possible. Thus their version of Anselm’s argument is inconclusive.
