Three very prominent arguments for atheism are (1) the argument from sub-optimality, (2) the problem of no best world, and (3) the evidential argument from gratuitous evil. To date, it has not sufficiently been appreciated that several important criticisms of these arguments have all relied on a shared strategy. Although the details vary, the core of this strategy is to concede that God either cannot or need not achieve the best outcome in the relevant choice situation, but to insist that (...) God must and can achieve an outcome that is good enough. In short, this strategy invokes divine satisficing in response to these arguments for atheism. (The widespread use of this strategy may have gone unnoticed because the appeal to divine satisficing is usually implicit.) In sections 1–3, the three arguments for atheism will be set out, and it will be shown that the relevant replies all employ this shared strategy. Section 4 will show that those who invoke divine satisficing have failed to establish that this is a coherent notion. Accordingly, these replies to three important arguments for atheism are, at present, incomplete. (shrink)

On my view, every bone, every fossil, and every putrid whiff of carrion that one smells on a hike in the country is just as good evidence for a divine intervention as it is for the suffering of an animal.

In Dialogues Concerning Natural Religion, Hume (1779/1993) appeals to his account of causation (among other things) to undermine certain arguments for the existence of God. If 'anything can cause anything', as Hume claims, then the Principle of Causal Adequacy is false; and if the Principle of Causal Adequacy is false, then any argument for God's existence that relies on that principle fails. Of course, Hume's critique has been influential. But Hume's account of causation undermines the argument from evil at least (...) as much as it undermines arguments for theism, or so I argue. I then suggest that Hume's account of causation can be used to formulate an alternative argument against classical theism. (shrink)

I formulate and defend a version of the many universes (or multiverse) reply to the atheistic argument from evil. Specifically, I argue that (i) if we know that any argument from evil (be it a logical or evidential argument) is sound, then we know that God would be (or at least probably would be) unjustified in actualizing our universe. I then argue that (ii) there might be a multiverse and (iii) if so, then we do not know that God would (...) be (or at least probably would be) unjustified in actualizing our universe. It follows that we cannot know that the atheistic argument from evil is sound, in which case we cannot be certain that the argument succeeds, and so it is rational to refuse to reject theism because of such arguments.

God is traditionally taken to be a perfect being, and the creator and sustainer of all that is. So, if theism is true, what sort of world should we expect? To answer this question, we need an account of the array of possible worlds from which God is said to choose. It seems that either there is (a) exactly one best possible world; or (b) more than one unsurpassable world; or (c) an infinite hierarchy of increasingly better worlds. Influential arguments (...) for atheism have been advanced on each hierarchy, and these jointly comprise a daunting trilemma for theism. In this paper, I argue that if theism is true, we should expect the actual world to be a multiverse comprised of all and only those universes which are worthy of creation and sustenance. I further argue that this multiverse is the unique best of all possible worlds. Finally, I explain how his unconventional view bears on the trilemma for theism. (shrink)

God is traditionally understood to be a perfect being who is the creator and sustainer of all that is. God's creative and sustaining activity is often thought to involve choosing a possible world for actualization. It is generally said that either there is (a) exactly one best of all possible worlds, or there are (b) infinitely many increasingly better worlds, or else there are (c) infinitely many unsurpassable worlds within God's power to actualize. On each view, critics have offered arguments (...) for atheism that turn on God's choice of a world. In what follows, I first discuss some background issues, and I then survey the contemporary literature on these arguments. (shrink)

In the space of possible worlds, there might be a best possible world (a uniquely best world or a world tied for best with some other worlds). Or, instead, for every possible world, there might be a better possible world. Suppose that the latter is true, i.e., that there is no best world. Many have thought that there is then an argument against the existence of God, i.e., the existence of an omnipotent, omniscient and morally perfect being; we will call (...) such arguments no-best-world arguments. In this paper, we discuss ability-based objections to such arguments; an ability-based objection to a no-best world argument claims that the argument fails because one or more of its premises conflict with a plausible principle connecting the applicability of some type of moral evaluation to the agent’s possession of a relevant ability. In particular, we formulate and evaluate an important new ability-based objection to the most promising no-best world argument. (shrink)

This paper treats two problem cases in decision theory, the Newcomb problem and Reed Richter''s Button III. Although I argue that, contrary to Richter, the latter case does not constitute a genuine counterexample to a standard general proposition of (causal) decision theory, I agree with and undertake to amplify his solution to the decision problem in Button III. I then apply the conclusions and distinctions in the foregoing treatment of Button III to the Newcomb problem and argue that a familiar (...) version of the dominance argument for taking both boxes runs afoul of plausible general constraints on rational agency. The underlying theme of the paper is that basic considerations of epistemic coherence play an important role in dealing with problem cases in decision theory. (shrink)

William Rowe in his Can God be Free? argues that God, if there is a God, necessarily chooses the best. Combined with the premise that there is no best act of creation, this provides an a priori argument for atheism. Rowe assumes that necessarily God is a ‘morally unsurpassable’ being, and it is for that reason that God chooses the best. In this article I drop that assumption and I consider a successor to Rowe ’s argument, the Argument from Arbitrariness, (...) based on the premise that God does not act arbitrarily. My chief conclusion will be that this argument fails because, for all we know, there can be non- arbitrary divine choices even if there is no best act of creation. (shrink)

Richard Swinburne has given a defense of arguments for the existence of God (and in particular of teleological arguments) in his book "The Existence of God" (1979/1991). This paper argues that such theistic arguments fail, and poses some general problems for theistic arguments. Swinburne's use of a principle of simplicity is not given adequate justification and, if justified, works against theism. There are adequate rebuttals to Swinburne's arguments that depend upon there being few particles of basic physics, universal laws of (...) nature, cogent cosmological argument, and temporal order in the universe. Theistic arguments falter on malleability, on going well beyond evidence, on anthropomorphism, on treating consistency as if it were evidence or explanation, on selective and inconsistent use of principles, and on a lack of any serious attempt to disprove hypotheses. All of this serves to support the conclusion suggested by Hume's posthumous theological writings that theistic arguments are so malleable, profligate, overreaching, equivocal, anthropomorphic, selective, inconsistent, and uncritical as to be inept.

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)

Interpersonal disagreement happens all the time. How to properly characterize interpersonal disagreement and how to respond to it are important problems, but the existence of such disagreements at least is obvious. The existence of intrapersonal disagreement, however, is another matter. On the one hand, we do change our minds sometimes, especially when new evidence comes in, and so there is a clear enough sense in which we can be characterized as having disagreements with our past selves. But what about synchronic (...) disagreements with ourselves? Are such cases possible, or is there something about the nature of belief that rules out the possibility of knowingly holding beliefs which cannot be rationally held at the same time? In this paper, I argue that there can be cases of intrapersonal synchronic disagreement, and that such disagreements can be deep, in the same way that interpersonal disagreements can be deep. For intrapersonal disagreements, just like interpersonal disagreements, can be grounded in conflicting frameworks for interpreting and reasoning about the world. I also argue that synchronic intrapersonal disagreements are peer disagreements. The paper ends with a discussion of four possible responses to interpersonal deep disagreements, concluding that if those responses are sometimes rational responses in the interpersonal case, then they are also sometimes rational responses in the intrapersonal case.

The more you think about it, the more baffling Newcomb's Problem becomes. To most people, at first it is obvious which solution is correct, but their confidence can be eroded easily. Only a puzzled few are torn between the two right from the start, and for years so was I. But at last, thanks to a certain metaargument, one solution came to seem obvious to me. And yet, imagining myself actually faced with Newcomb's choice, I started to worry that I (...) might experience just enough last-minute ambivalence to unsettle my confidence in that argument. Fortunately, I have found a strategy to ensure making the right choice when the chips are down.Not only is Newcomb's Problem puzzling in its own right, it is philosophically significant. The appeal of both solutions reflects a conflict between two plausible conceptions of rational choice. In making a decision, should one consider all of its probabilistic consequences or only its causal consequences? Each conception has its supporters, but some philosophers find them both defensible and see no hope of resolving the conflict. I think the conflict can be resolved, at least in the context of Newcomb's Problem, by properly assessing the relevant counterfactual conditionals. (shrink)

In a recent article (Kraay 2013), I argued that some prominent responses to two important arguments for atheism invoke divine satisficing – and that the coherence and propriety of this notion have not been established. Chris Tucker (2016) agrees with my evaluation of divine satisficing, but disagrees with my exegesis of these responses. He argues that they should be understood as invoking motivated submaximization instead. After reviewing the dialectical situation to date, I assess whether motivated submaximization can be deployed in (...) such a way as to defeat these argument for atheism. I argue that it’s far from clear that it can. (shrink)
