This idea has a “victorious” version outlined in the book The Nature of Necessity. Charles Hartshorne used the idea of dipolar attributes as the basis for the “cumulative case” strategy to amend this idea. This idea is extended in the fifth section of (*) Meditations on First Philosophy by Descartes, as well as in a “modal” version by Alvin Plantinga. This argument is attacked in the text In Behalf of the Fool through a “Lost Island” rebuttal created by Gaunilo. This argument first appeared in the Proslogion and imagines a “supremely perfect” entity. For 10 points, name this argument for the existence of God put forward by Saint Anselm, which is named for the philosophical study of being. ■END■
