  Gaunilo’s counterargument is so ingenious that it stands out as by far the most devastating criticism in his catalogue of Anselm’s errors. Not surprisingly, then, interpreters have read Anselm’s reply to Gaunilo primarily in order to find his rejoinder to the Lost Island argument.  Sympathetic interpreters (such as Klima 2000 and Ward 2018) have offered ways for Anselm to respond, but at least one commentator (Wolterstorff 1993) argues that Anselm offers no such rejoinder, precisely because he knew Gaunilo’s criticism was unanswerable but could not bring himself to admit that fact.
