It is sometimes argued that if God were to exist, then the actual world would be the best possible world. However, given that the actual world is clearly not the best possible world, then God doesn’t exist. In response, some have argued that the world could always be improved with the creation of new people and that there is thus no best possible world. I argue that this reasoning (...) gives rise to an instance of Parfit’s mere addition paradox and should thus be rejected. Others (Robert Adams, in particular) have argued that the actual world may, in fact, be the best possible world, at least for all actual people. I argue that this reasoning gives rise to Parfit’s non-identity problem and should thus be rejected. (shrink)

I reply to David Basinger who, in an article printed in the same issue, develops objections to my original argument (IPQ XIX, 203-212) that it makes no sense to inquire whether God could create the best possible world since the concept of a best possible world is a meaningless notion. I argue that if the number of possible worlds is infinite, there cannot be an upper limit to this order, and without an upper (...) limit, there can be no best possible world. (shrink)

I ARGUE THAT THE NOTION OF THE BEST POSSIBLE WORLD IS MEANINGLESS AND THEREFORE A CHIMERA, BECAUSE FOR ANY WORLD WHICH MIGHT BE SO DESIGNATED, THERE COULD ALWAYS BE ANOTHER WHICH WAS BETTER, EITHER IN BEING POPULATED BY BEINGS WITH BETTER OR A GREATER QUANTITY OF GOOD CHARACTERISTICS, OR ELSE BY BEING MORE OPTIMIFIC.

Many have argued that if God exists then he must necessarily create the best possible world , which entails that the bpw necessarily exists, and is therefore the only possible world. But without any scope for comparison, the superlative term ‘best’ is clearly inappropriate and so the bpw cannot be the bpw at all! As such, it must be impossible for God to create it. Hence if God exists then he must of necessity make (...) something that is impossible to create! Because of its conclusion, I call this the repugnant argument. I consider a number of possible responses to this argument. (shrink)

A number of analytic philosophers of religion have asserted what we will call proposition : If God creates the best possible world from an internal necessity alone, then God cannot be thankworthy with respect to creating the best possible world. According to, there is inconsistency between divine thankworthiness and the idea that God creates the best possible world from an internal necessity alone. In this article, however, I develop an argument for (...) the consistency of divine thankworthiness and the idea that God creates the best possible world from an internal necessity alone, thus claiming that proposition is false. An exploration into the Judeo-Christian doctrine of divine grace will expedite the argument. This doctrine will provide sufficient grounds for thinking that God is thankworthy with respect to creating the best possible world. I also argue that the idea that God creates the best possible world from an internal necessity alone can also be a gracious act. Along the way, I will consider possible objections to my argument.

Since the 1960s an increasing number of philosophers have endorsed the thesis that there can be no such thing as “the best possible world.” In this paper I examine the main arguments for this thesis as put forth by George Schlesinger, Alvin Plantinga, Bruce Reichenbach, Peter Forrest, and Richard Swinburne. I argue that none of these arguments succeed in establishing the thesis and that the logical possibility of the best possible world is as yet (...) an open question. (shrink)

In this article I argue that the Critical Kant endorses the claim that God creates the best possible world, and that this claim is best understood as committing him to the view that God creates an infinitely valuable world. Kant’s understudied Critical theory of the best possible world differs significantly from his better-known quasi-Leibnizian pre-Critical account insofar as it uses an axiological rather than ontological metric for the goodness of worlds. The axiological (...) metric introduces unique challenges for a Kantian account of the best possible world. These challenges are in turn resolved via an infinite value interpretation. (shrink)

Leibniz has long faced a challenge about the coherence of the distinction between necessary and contingent truths in his philosophy. In this paper, I propose and examine a new way to save genuine contingency within a Leibnizian framework. I conclude that it succeeds in formally solving the problem, but at unbearable cost. I present Leibniz’s challenge by considering God’s choice of the best possible world (Sect. 2). God necessarily exists and necessarily chooses to actualise the best (...) possible world. The actual world therefore could not be different, for if it were different it would be a distinct and inferior world and hence would not be created. In Sect. 3 I defend Leibniz from this challenge. I argue that while it is necessary for God to choose to create the best possible world, it is not necessary for any world to be the best possible. This is because the criterion for judging perfection can itself be contingent. Different criteria will judge different worlds as the best. Thus it is necessary for God to create the best, but not necessary which is the best. Distinguishing between possible worlds in Leibniz’s sense and in the modern sense allows a fuller exposition of this position. There are worries that can arise with the claim that the criterion of perfection is contingent. I consider two of the most pressing (Sect. 4). The first argues that the criterion is in God’s understanding and hence is necessary; the second alleges that a contingent criterion of perfection violates Leibniz’s cherished Principle of Sufficient Reason. These worries are well-grounded, and examining them reveals a deep incompatibility between this solution and Leibniz’s metaphysical views. I conclude that there is a real solution available, but that it is unacceptable to Leibniz or a Leibnizian. The search for a genuine solution that is genuinely Leibnizian goes on. (shrink)

In the 1750s Optimism, the Leibnizian doctrine that the actual world is the best possible world, popularised by Pope in 1733 in his Essay on Man, was a hot topic. In 1759 Kant wrote and published a brief essay defending Optimism, Attempt at some Reflections on Optimism. Kant’s aim in this essay is to establish that there is one and only one best possible world. In particular, he argues against the claim that, for (...) every possible world, there is a possible world better than it and against the claim that there are two or more equally good possible worlds that are better than all the rest. Although it is not clear why, Kant was later dissatisfied with his essay. In this article I shall reconstruct, discuss, and evaluate Kant’s arguments. My evaluation will be negative, and so I think Kant had reasons to be dissatisfied with his essay. (shrink)

Robert Merrihew Adams argues that it is permissible for a perfectly good moral agent to create a world less good than the best one she could create. He argues that God would exhibit the important virtue of grace in creating less than the best and that this virtue is incompatible with the merit considerations required by the standard of creating the best. In this paper I give three arguments for the compatibility of merit consideration and graciousness (...) of God toward creation. I conclude that grace would not release a perfect agent from responsibility to create the best. (shrink)

Well‐known arguments for atheism have been grounded on the alleged lack of morally justifying reasons to permit particular moral and natural evils and on the thesis that God would have to create the best possible world. After discussing obstacles to the suggestion that there is a best of all possible worlds, I examine the prospects for responding to these atheistic arguments by exploring the case for our own world's being the best of all (...) possible worlds against the backdrop of the multiverse hypothesis – an intriguing claim about the partitioned structure of reality that has been receiving serious and recent attention in philosophy and physics.

In this paper I claim that in Leibniz’s metaphysics we can use the term ‘world’ in a twofold sense. On the one hand to refer to highly complex divine thoughts, i.e. the ideal realm, and on the other hand to refer to a network of living substances with their perceptions and appetitions, i.e. the substantial realm. First of all, I will clarify the ideal realm in Leibniz's metaphysics, which consists of three combinatorial levels about the fundamental entities, namely the (...) simple ideas in God's mind: complex ideas, complete individual notions and possible worlds. The second part is about the individual substances, i.e. the monads. In the third section, fnally, I will discuss different ways to think about the connection between both worlds—how the best possible world is linked to the actual monadic world. (shrink)

The concept of the best of all possible worlds is widely considered to be incoherent on the grounds that, for any world that might be termed the best, there is always another that is better. I note that underlying this argument is a conviction that the goodness of a world is determined by a single kind of good, the most plausible candidates for which are not maximizable. Against this I suggest that several goods may have (...) to combine to determine the goodness of a world, and because of logical conflicts between them, the goods can be optimized to give a genuine best of all possible worlds. (shrink)

Leibniz argued that God would not create a world unless it was the best possible world. I defend Leibniz’s argument. I then consider whether God could refrain from creating if there were no best possible world. I argue that God, on pain of contradiction, could not refrain from creating in such a situation. I conclude that either this is the best possible world or God is not our creator.

The Argument from Inferiority holds that our world cannot be the creation of an omnipotent and omnibenevolent being; for if it were, it would be the best of all possible worlds, which evidently it is not. We argue that this argument rests on an implausible principle concerning which worlds it is permissible for an omnipotent being to create: roughly, the principle that such a being ought not to create a non-best world. More specifically, we argue (...) that this principle is plausible only if we assume that there is a best element in the set of all possible worlds. However, as we show, there are conceivable scenarios in which that assumption does not hold. (shrink)

Certainly NBPW can justify metaphysical evil, which is all Leibniz intended it to do. Probably, as suggested by Bruce Reichenbach, NBPW can rebut an atheistic argument from the non-existence of the best possible world. It could even augment a GGD by defending against a divine obligation to have created a “larger” world. But NBPW by itself cannot serve to derail the logical problem of evil in any way whatsoever; theists must find refuge in a GGD if (...) they are to find it at all. Lacking a GGD, NBPW is irrelevant; given a GGD, NBPW is superfluous. (shrink)

In “The Best of All Possible Worlds” William E. Mann argues that some possible worlds are morally incommensurable with some others, because some choices are between incompatible alternatives that are themselves incommensurable. The best possible world must be better than, and hence commensurable with, every other world. So if anyone in the actual world ever faces a choice between incompatible alternatives that are morally incommensurable, this is not the best possible (...) world. But it seems that some of us do, on occasion, face such choices. So this is not the best possible world. (shrink)

A common argument for atheism runs as follows: God would not create a world worse than other worlds he could have created instead. However, if God exists, he could have created a better world than this one. Therefore, God does not exist. In this paper I challenge the second premise of this argument. I argue that if God exists, our world will continue without end, with God continuing to create value-bearers, and sustaining and perfecting the value-bearers he (...) has already created. Given this, if God exists, our world—considered on the whole—is infinitely valuable. I further contend that this theistic picture makes our world's value unsurpassable. In support of this contention, I consider proposals for how infinitely valuable worlds might be improved upon, focusing on two main ways—adding value-bearers and increasing the value in present value-bearers. I argue that neither of these can improve our world. Depending on how each method is understood, either it would not improve our world, or our world is unsurpassable with respect to it. I conclude by considering the implications of my argument for the problem of evil more generally conceived. (shrink)

The space of possible worlds is vast. Some of these possible worlds are materialist worlds, some may be worlds bottoming out in 0s and 1s, or other strange things we cannot even dream of… and some are idealist worlds. From among all of the worlds subjectively indistinguishable from our own, the idealist ones have uniquely compelling virtues. Idealism gives us a world that is just as it appears; a world that’s fit to literally enter our minds (...) when we perceive it. If the world is an idealist world, we live in a perceptual Eden. We did not fall from Eden. Rather, we deluded ourselves into believing that we couldn’t possibly live in Eden when we committed to materialism. Reflecting on these big-picture issues gives us reason to question this commitment and embrace a radically new account of reality and our relation to it. (shrink)

Leibniz said that the universe, if God-created, would exist at a unique, conjoint, physical maximum: Of all possible worlds, it would be richest in phenomena, but its richness would arise from the simplest physical laws and initial conditions. Using concepts of ‘‘variety’’ and algorithmic informational complexity, Leibniz’ claim can be reframed as a testable theory. This theory predicts that the laws and conditions of the actual universe should be simpler, and the universe richer in phenomena, than the presence of (...) observers would require. Tegmark has shown that inhabitants of an infinite multiverse would likely observe simple laws and conditions, but also phenomenal richness just great enough to explain their existence. Empirical observations fit the claim of divine choice better than the claim of an infinite multiverse. The future of the universe, including its future information-processing capacity, is predicted to be endless. -/- . (shrink)

Steven Nadler hopes to interest a readership wider than just professional philosophers in a largely forgotten debate he admits was not one of philosophy’s “marquee events.” It sounds like an uphill battle, even for a writer as skilled and for a historian of modern philosophy as accomplished as Nadler. Yet The Best of All Possible Worlds succeeds in unfolding a compelling tale without distorting the fundamental doctrines of its protagonists.And what protagonists they were, however much the passing centuries (...) have dimmed their renown. G. W. Leibniz is still likely to have some name recognition with the target audience. But it would be unsafe to assume it for either the Oratorian Nicolas Malebranche or the Jansenist Antoine Arnauld. So Nadler weaves enough historical and biographical detail into his story, both to introduce all three and to create a background of human interest against which their philosophical differences are displayed.

The quantitative argument against the notion of a best possible world claims that, no matter how many worthwhile lives a world contains, another world contains more and is, other things being equal, better. Parfit’s ‘ Mere Addition Paradox ’ suggests that defenders of this argument must accept his ‘ Repugnant Conclusion ’ : that outcomes containing billions upon billions of lives barely worth living are better than outcomes containing fewer lives of higher quality. Several responses (...) to the Paradox are discussed and rejected as either inadequate or unavailable in a theistic context. The quantitative argument fails if some world is such that addition to it is not possible, i.e., if it is intensively infinite, as Liebniz claimed. If the notion of such a world is incoherent, then no world is quantitatively best and the quantitative argument succeeds, but only at the cost of embracing the Repugnant Conclusion. (shrink)

Leibniz’s claim that we live is the best of all possible worlds is in contradiction with our experience, which is why we tend to maintain that the world would become better if at least some of its properties and characteristics were different. Leibniz criticized such an approach and argued that every attempt at changing the world would make it worse, or even impossible. His claim seems to be in contradiction with the Christian belief that our (...) class='Hi'>world is contaminated with sin, but it will be renewed in the end to become the reality of salvation, i.e. the best of all possible realities. This article puts forward two arguments: (1) Leibniz’s claim is not in contradiction with the Christian belief in salvation; (2) Leibniz’s claim is in contradiction with the human experience of the world because it is a result of an intellectual speculation based on the false assumption that the structure of the human mind adequately corresponds to the mind of God.

An increasingly prevalent practice in defending current concepts of democracy is to make it synonymous with Americanization. Creating a world order permeated by the economic and cultural values of contemporary Western elites is taken to be equivalent to promoting a democratic future for everyone in The Real World Order — a work by two futurologists, Max Singer and Aaron Wildavsky, praised by such global democratic advocates as Robert O. Keohane, Francis Fukuyama, Bruce Bueno de Mesquita, and by the (...) Times Literary Supplement for its “injection of sensible balance into discussions of international relations.” Singer and Wildavsky explain that although “democracy and modern wealth are new in the world,” they have now come to define the major economic and political powers.

In the first section of this paper I discuss what Leibniz meant by a miracle and why Leibniz’s definition of the best of all possible worlds implies that it is a world in which miracles are minimized. In the second part of the paper I argue that human happiness within the best of all possible worlds also requires, on Leibniz’s principles, that miracles must there be minimized. In the third section of the paper I consider (...) what, if any, miracles actually remain possible for Leibniz within the best of all possible worlds. In the final section I discuss one important kind of event upon which Leibniz vacillated whether it required miraculous intervention -- namely, the elevation of the sensitive soul to rationality -- and some speculation about the cause of this vacillation in Leibniz is offered.

Olga Plümacher (1839–1895) published a book entitled Der Pessimismus in Vergangenheit und Gegenwart in 1884. It was an influential book: Nietzsche owned a copy, and there are clear cases where he borrowed phraseology from Plümacher. Plümacher specifies philosophical pessimism as comprising two propositions: ‘The sum of displeasure outweighs the sum of pleasure’ and ‘Consequently the non-being of the world would be better than its being’. Plümacher cites Schopenhauer as the first proponent of this position, and Eduard von Hartmann as (...) the thinker who has developed it to its fullest potential. She heavily criticizes Schopenhauer in many respects, not for being a pessimist, but rather for not achieving as good a pessimism as he might have done, on the following major grounds: that his account of pleasure as merely privative is implausible, that he has a confused account of individuation, that his retention of a Christian notion of guilt is gratuitous, that he lapses into the self-pitying subjectivity of the condition she calls Weltschmerz, and that his philosophy leads to quietism, and is thus inferior to von Hartmann’s combination of pessimism and optimism, which allows for social progress.

In his account of his Düsseldorf conversations with G.E. Lessing shortly before the latter’s death in 1781, F.H. Jacobi records the Enlightenment poet and philosopher’s allusion to the Kabbalistic philosophy of Henry More, whom he cited in support of his shocking Spinozist creed of the hen kai pan. Origen’s first Christian philosophy hinges upon a conviction of universal divine goodness which cannot but share its riches with beings capable of participating in it by virtue of their own free will. From (...) this first Christian truth flow the infamous doctrines of the pre-existence of souls and, above all, the restitution of all things envisaged as a never-ending process of autonomous moral soul-making. Origen’s philosophy of divine goodness and human freedom appealed deeply to the Cambridge Platonists Ralph Cudworth and Henry More, who cited the Church Father in support of their metaphysics of God’s benignity and man’s free will. German rationalist G.W. Leibniz was also a close reader of Cudworth and More. Both his Theodicy and his Monadology—notably the notion of a best possible world created by a good God and inhabited by self-improving spiritual monads—are indebted to the Church Father’s Christian philosophy. G.E. Lessing, reviewing the controversial discussions about the apokatastasis in his day, staunchly defended Leibniz’s Origenist rationalism in several works devoted to his philosophical eschatology. Above all, he restated Origen’s notion of salvation as divine pedagogy in his celebrated Education of the Human Race. The present essay establishes the deeply Origenist character of the historic systems of these two seminal German rationalists, with their shared concern for God’s creative goodness and man’s free perfectibility.

As the opening line of Dickens' classic novel suggests, it is very often the case that people can imagine both better and worse alternatives to their present reality. Although Dickens was writing about events that occurred over two centuries ago, it remains just as true today that we clearly live in neither the best nor the worst of possible worlds. For instance, we can wish for the amelioration of present difficulties in the Middle East yet still take comfort (...) in the fact that the threat of nuclear war has been greatly reduced since the end of the Cold War. On a more mundane level, it is easy for us to imagine how various aspects of our lives, such as our jobs, marriages, or physical fitness, could be both better and worse. Undoubtedly due to the pervasiveness and intrinsically fascinating qualities of this phenomenon of imagining alternatives to reality, there has been a veritable explosion of research in recent years on what have been termed mental simulation and counterfactual thinking processes. This chapter speculates upon and provides evidence for the antecedents and consequences of two types of counterfactuals: upward (it could have been better) and downward (it could have been worse). The importance of studying the antecedents and consequences of counterfactual direction lie in the differential structures, emotions, intentions, inferences, and behavioral consequences of upward versus downward counterfactual thinking.

William L. Rowe’s argument against divine freedom has drawn considerable attention from theist philosophers. One reply to Rowe’s argument that has emerged in the recent literature appeals to modified accounts of libertarian freedom which have the result that God may be free even if he necessarily actualizes the best possible world. Though in many ways attractive, this approach appears to lead to the damning consequence of modal collapse i.e., that the actual world is the only (...) class='Hi'>possible world. But appearances can be deceiving, and in this paper I argue that the threat of modal collapse dissolves when we consider Alvin Plantinga’s critique of the purportedly Leibnizian notion that God can actualize any possible world, and incorporate the implications of this critique into the divine freedom debate. Developing a suggestion by Edward R. Wierenga, I argue first that the modal collapse objection fails within a Molinist context, and then I extend the discussion beyond that context to show that the objection also fails on the assumption that Molinism is false.

In this article I explore Leibniz's claim in the Theodicy that on the essential points Malebranche's theodicy "reduces to" his own view. This judgment may seem to be warranted given that both thinkers emphasize that evils are justified by the fact that they follow from the simple and uniform laws that govern that world which is worthy of divine creation. However, I argue that Leibniz's theodicy differs in several crucial respects from Malebranche's. I begin with a qualified endorsement of (...) Charles Larmore's recent claim that remarks in Malebranche's correspondence with Leibniz indicate that their theodicies rely on incompatible conceptions of the moral rationality of divine action. I also attempt to go beyond Larmore's discussion in highlighting further differences concerning the sort of freedom involved in the divine act of creation. My conclusion is that these differing conceptions of divine morality and divine freedom reveal that in contrast to the case of Leibniz, Malebranche's theodicy not only does not require that God create anything at all, but also is compatible with the result that the world he decides to create is not uniquely the best possible.
