Abstract

This paper is a defense of the view that existence is a perfection. Anselm’s First Ontological Argument is referred to throughout. Two major objections are advanced: the ‘perfect island’ objection and the ‘perfect devil’ objection. A rebuttal of both, based on Anselm’s reply to Gaunilo, is tendered, but itself faces a major objection. Two lines of defense against this objection are possible. The first is sympathetically explained but it is argued that it ultimately fails. The second, which focuses on the idea of a perfection and a perfect being, is elaborated and defended against a seemingly powerful objection. It is concluded that there is a reasonable interpretation of the claim that existence is a perfection.
