I provide the account of divine creation found in multiverse theorists Donald Turner, Klaas Kraay, and Tim O’Connor. I show that the accounts Kraay and Turner offer are incoherent. God does not survey all possible worlds and necessarily actualize those universes in the (on balance) good worlds or the worthy worlds. If God necessarily actualizes the multiverse, we have no idea which universes are parts of that multiverse. I show next that Tim O’Connor’s multiverse account of creation is also incoherent. I argue that a preferable multiverse would include a much greater variety of universes than are included in Turner, Kraay or O’Connor. In the last section I offer some concluding remarks.

This chapter shows that, (i) necessarily, God is able to actualize a morally and naturally perfect world, but (ii) it is _impossible_ that, necessarily, God _does_ actualize a morally and naturally perfect world. This is called the Impossibility Argument. This chapter shows further that the Impossibility Argument is valid on any concept of free will: libertarianism, weak compatibilism, and strong compatibilism. The chapter concludes that theists have available to them a successful argument against the logical problem of evil that does not depend on any particular concept of free will. If God is permitted to actualize a morally and naturally perfect world, then God can coexist with evil. And the logical problem of evil is solved.

Suppose it is a reasonable assumption that there is no possible world that is overall highest in value. Some theists have found in thatassumption a basis for actualizing a less-than-best world. Some atheists have found in that assumption a basis for actualizing no world at all. I present a dynamic choice model for the problem and describe the rationality assumptions necessary to generate a rational choice problem for an ideally rational agent. I show that at least one of the rationality assumptions—the Rational Perfection Principle—is invalid in the relevant sorts of models. I conclude that the existence of no best world presents no rational choice problem for ideally rational agents.

The book discusses the structure, content, and evaluation of cosmological arguments. The introductory chapter investigates features essential to cosmological arguments. Traditionally, cosmological arguments are distinguished by their appeal to change, causation, contingency or objective becoming in the world. But none of these is in fact essential to the formulation of cosmological arguments. Chapters 1-3 present a critical discussion of traditional Thomistic, Kalam, and Leibnizian cosmological arguments, noting various advantages and disadvantages of these approaches. Chapter 4 offers an entirely new approach to the cosmological argument - the approach of theistic modal realism. The proper explananda of cosmological arguments on this approach is not change, causation, contingency or objective becoming in the world. The proper explananda is the totality of metaphysical reality - all actualia and all possibilia. The result is the most compelling and least objectionable version of the cosmological argument.

The main aim in the forthcoming discussion is to contrast theistic modal realism and theistic actualist realism. Actualist realism is the dominant view among theists and presents the most serious challenge to theistic modal realism. I discuss various prominent forms of theistic actualist realism. I offer reasons for rejecting the view of metaphysical reality that actualist realism affords. I discuss theistic modal realism and show that the traditional conception of God is perfectly consistent with the metaphysics of genuine modal realism. Indeed theistic modal realism is more suited to traditional theism than is any version of actualist realism.

I distinguish restrictive and permissive multiverse solutions to the problems of evil and no best world. Restrictive multiverses do not admit a single instance of gratuitous evil and they are not improvable. I show that restrictive multiverses unacceptably entail that all modal distinctions collapse. I consider Timothy O’Connor’s permissive multiverse. I show that a perfect creator minimizes aggregative suffering in permissive multiverses only if the actual universe is not included in any actualizable multiverse. I conclude that permissive multiverses do not offer a credible solution to the problems of evil and no best world.

In his most recent version of the evidential argument from evil, William Rowe argues that the observation of no outweighing goods for certain evils constitutes significant evidence against theism. I show that the new evidential argument cannot challenge theism unless it is also reasonable to believe that no good we know of justifies God in permitting any evil at all. Since the new evidential argument provides no reason at all to believe that God is not justified in permitting any existing evil, I conclude that Rowe's argument presents no evidential challenge to theism.

William Rowe has argued that if there is an infinite sequence of improving worlds then an essentially perfectly good being must actualize some world in the sequence and must not actualize any world in the sequence. Since that is impossible, there exist no perfectly good beings. I show that Rowe's argument assumes that the concept of a maximally great being is incoherent. Since we are given no reason to believe that the concept of a maximally great being is incoherent we have no reason to believe Rowe's Argument from Improvability is sound
