Abstract
Of these discussions the last, from the Summa Theologiae, is the best known and is often taken as representative of Thomas’ response to Anselm. Yet it would seem, on the face of it, unsatisfying as a refutation. Gareth Matthews’ comment expresses a very widely shared reaction: "Instead of showing that Anselm’s argument is invalid, Aquinas seems content to state, without counterargument, that the alleged conclusion does not follow." To many, Thomas’ critique represents no advance beyond Gaunilo in understanding Anselm, but merely reproduces Gaunilo’s objection against Proslogion III in Pro Insipiente VII, and his critique has even evoked from one of the most influential modern proponents of Anselm’s argument the remark "This is not very perceptive, is it?" Such an attitude has, as one might expect, hardly been modified by the satisfaction with which Thomists often regard Thomas’ rebuttal while ignoring both the logic of the argument and the details of Thomas’ reply to it.
