In this paper, I shall present and defend an ontological argument for the existence of God. The argument has two premises: possibly, God exists, and necessary existence is a perfection. I then defend, at length, arguments for both of these premises. Finally, I shall address common objections to ontological arguments, such as the Kantian slogan, and Gaunilo-style parodies, and argue that they do not succeed. I conclude that there is at least one extant ontological argument that is plausibly sound.

A common view among nontheists combines the de jure objection that theism is epistemically unacceptable with agnosticism about the de facto objection that theism is false. Following Plantinga, we can call this a “proper” de jure objection—a de jure objection that does not depend on any de facto objection. In his Warranted Christian Belief, Plantinga has produced a general argument against all proper de jure objections. Here I first show that this argument is logically fallacious (it makes subtle probabilistic fallacies (...) disguised by scope ambiguities), and proceed to lay the groundwork for the construction of actual proper de jure objections.

Michael Almeida once told me that he thought we were just a couple of hours of conversation away from reaching deep agreement about some important topics in the philosophy of religion pertaining to God, multiverses, and modality. This paper represents my attempt to move this conversation forward and to seek this common ground. Specifically, I respond to Almeida’s paper entitled “The Multiverse and Divine Creation”. In the first four sections, I record my disagreement with him concerning some smaller matters. In (...) Section 5, I try to persuade him that what he considers a ‘bug’ in the theistic multiverse is actually a feature—and a desirable one at that. In Section 6, I close by identifying some points at which our views seem to converge. (shrink)
