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.

_The Metaphysics of Perfect Beings_ addresses the problems an Anselmian perfect being faces in contexts involving unlimited options. Recent advances in the theory of vagueness, the metaphysics of multiverses and hyperspace, the theory of dynamic or sequential choice, the logic of moral and rational dilemmas, and metaethical theory provide the resources to formulate the new challenges and the Anselmian responses with an unusual degree of precision. Almeida shows that the challenges arising in the unusual contexts involving unlimited options sometimes produce metaphysical surprise.

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.

Some carnivores defend the position that the opportunistic consumption of meat is morally permissible even under the assumption that it is morally wrong to act in ways that ause unnecessary suffering to sentient beings. Ordering and consuming chicken once a week, they argue, will not increase the numbers of chickens suffering or slaughtered, since the system of purchasing and farming chickens is not sufficiently fine‐tuned to register differences at margin. We argue that, insensitivity of the market notwithstanding, consistent consequentialists are morally prohibited from each additional purchase and consumption of meat.

ABSTRACT: Recent work in moral theory includes an intriguing new argument that the vagueness of moral properties, together with two well-known and well-received metaethical principles, entails the incredible conclusion that it is impossible to be moral. I show that the argument equivocates between “it is true that A and B are morally indistinguishable” and “it is not false that A and B are morally indistinguishable.” As expected the argument is interesting but unsound. It is therefore not impossible to be moral.RÉSUMÉ: Les travaux récents en théorie morale comprennent un nouvel argument intrigant voulant que le caractère vague des propriétés morales, joint à deux principes métaéthiques bien connus et généralement admis, entraîne une conclusion incroyable, soit qu’il est impossible d’être moral. Je montre que cet argument entretient l’équivoque entre «il est vrai que A et B sont moralement impossibles à distinguer» et «il n’est pas faux que A et B soient moralement impossibles à distinguer». Comme on s’y attendait, l’argument est intéressant mais mal fondé. Il n’est donc pas impossible d’être moral.
