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. (shrink)

Modal ontological arguments argue from the possible existence of a perfect being to the actual (necessary) existence of a perfect being. But modal ontological arguments have a problem of symmetry; they can be run in both directions. Reverse ontological arguments argue from the possible nonexistence of a perfect being to the actual (necessary) nonexistence of a perfect being. Some familiar points about the necessary a posteriori, however, show that the symmetry can be broken in favour of the ontological argument.

Otte :165–177, 2009) and Pruss :400–415, 2012) have produced counterexamples to Plantinga’s famous free will defence against the logical version of the problem of evil. The target of this criticism is the possibility of universal transworld depravity, which is crucial to Plantinga’s defence. In this paper, we argue that there is a simpler and more plausible free will defence that does not require the possibility of universal transworld depravity or the truth of counterfactuals of creaturely freedom. We assume only that (...) libertarianism is possibly true and that God’s existence is consistent with the existence of free agents who never go wrong. We conclude the paper by explaining how our defence may be able to succeed without assuming, in a way that is consistent with compatibilism. (shrink)
