Traditional theistic arguments conclude that God exists. Pragmatic theistic arguments, by contrast, conclude that you ought to believe in God. The two most famous pragmatic theistic arguments are put forth by Blaise Pascal (1662) and William James (1896). Pragmatic arguments for theism can be summarized as follows: believing in God has significant benefits, and these benefits aren’t available for the unbeliever. Thus, you should believe in, or ‘wager on’, God. This article distinguishes between various kinds (...) of theistic wagers, including finite vs. infinite wagers, premortem vs. postmortem wagers, and doxastic vs. acceptance wagers. Then, we’ll turn to the epistemic-pragmatic distinction, and discusses the nuances of James’ argument, and how views like epistemic permissivism and epistemic consequentialism provide unique “hybrid” wagers. Finally, we’ll cover outstanding objections and responses. (shrink)

This paper develops a new argument from consciousness to theism: the argument from psychophysical harmony. Roughly, psychophysical harmony consists in the fact that phenomenal states are correlated with physical states and with one another in strikingly fortunate ways. For example, phenomenal states are correlated with behavior and functioning that is justified or rationalized by those very phenomenal states, and phenomenal states are correlated with verbal reports and judgments that are made true by those very phenomenal states. We argue that (...) psychophysical harmony is strong evidence for theism (or, at least, strong evidence against atheism in its standard naturalistic form). (shrink)

The common consent argument claims that widespread belief in God is good evidence for God’s existence. Though taken seriously throughout the history of philosophy, the argument died in the 1800s. Our philosophy of religion textbooks ignore it. In this paper, we hope to resuscitate it drawing upon the demographics of religious belief, the cognitive science of religion, and contemporary epistemology. We develop and defend two common consent arguments, which maintain that widespread belief in a High God is good evidence (...) for theism over metaphysical naturalism. (shrink)

I outline and defend a version of the aesthetic argument for the existence of God, according to which theism explains our capacity for subjective aesthetic experience better than its major competitor, naturalism. I argue that naturalism fails to adequately explain the nature and range of our aesthetic experiences, since these are amenable neither to standard Darwinian explanation nor to explanation in terms of more complex sociobiological mechanisms such as sexual selection or between-group selection. I concede that aesthetic experience may (...) be an evolutionary spandrel but argue that the conjunction of this thesis with naturalism is highly improbable given the prevalence of beauty in the natural world. Theism, on the other hand, furnishes a robust personal explanation of aesthetic experience, since on theism God has both good reasons to bring such experiences about and the power to do so. I address an objection to the theistic explanation from broadly negative aesthetic experiences, arguing that God plausibly has many reasons to allow these. I contend that this formulation of the argument is superior to other extant versions, since it does not depend on controversial probability judgments, dubious analogies between natural phenomena and human artefacts, or objectivism about aesthetic values. (shrink)

C. Stephen Layman contends that an argument supporting theism over naturalism can be constructed based on three defensible, non–question-begging premises about the moral order. Previous critics of Layman’s argument have challenged the truth of these premises. We stipulate them arguendo but go on to show that there is a deeper problem: a fourth premise introduced to complete the argument—the “completion premise,” as we call it—is true only if we assume that God exists or we concede that there is no (...) afterlife. We close with suggestions for how Layman’s argument must be strengthened to meet with dialectical success. (shrink)

SummaryHolm Tetens develops in his book „Gott denken. Ein Versuch über rationale Theologie“ theoretical and practical arguments against a naturalistic and in favour of a theistic understanding of reality. In my paper I focus on Teten’s claim that we are rationally justified to hope for the truth of classical theism. I distinguish between rationally justified and unjustified forms of hope and argue that we are rationally justified to hope for the redemption of reality as promised by classical (...) class='Hi'>theism. However, this hope has a weaker basis of justification than Tetens seems to assume because serious objections to classical theism ought to be taken into consideration as well. (shrink)

Causal finitism claims nothing can have an infinite causal history. An influential defense of this position uses infinity paradoxes to argue that, if causal finitism is false, several impossible scenarios would be possible. In this paper, I defend that theists should not be persuaded by this argument. If true, this is an important development, since causal finitism is often argued for by theists as a core premise in Kalam-style cosmological arguments for theism. I extend the same analysis to (...) an argument in favor of temporal finitism and conclude that my point may generalize to any reasoning of a similar structure. (shrink)

In this paper, I argue that Islamic theism is best explained by the hypothesis of Divine Commission, whereby Muhammad is viewed as being divinely commissioned to serve the overall salvific purposes of God. To this end, I present three observation reports relating to Islamic theism and evaluate HDC against an alternative hypothesis, the hypothesis of Non-Commission whereby Muhammad is not viewed as being divinely commissioned. I argue that the probability of the observation reports is greater on the assumption (...) that HDC is true than on the assumption that NC is true. Accordingly, this gives us reason to prefer HDC as a better explanation of Islamic theism. (shrink)

In this paper I introduce the transcendental argument for Christian theism in the context of Reformed theologian and philosopher Cornelius Van Til’s thought. I then present the critique proffered by Barry Stroud against ambitious transcendental arguments, and survey various formulations of transcendental arguments in the literature, seeking how the objection bears upon them. I argue that Adrian Bardon’s (2005) interpretation is the most helpful in understanding the Stroudian objection. From this interpretation, two types of possible rebuttals are (...) deduced. Proceeding to survey the responses offered by Van Tillians to this objection in the recent literature, I discern two general strategies pursued in these responses, which map onto the previously deduced types of rebuttals: the Biblical justification strategy and the objection-undermining strategy. I argue that all the specific attempts to answer Stroud which I examine here (those of Butler, Bosserman, and Fluhrer) are inadequate and that these two strategies, in general, face serious problems. I conclude with considering the options before the proponent of the transcendental argument for Christian theism and with offering a new objection to the argument, which focuses on its inconsistency with the implications of Christian theism itself.

This paper consider three families of arguments for atheism. First, there are direct arguments for atheism: arguments that theism is meaningless, or incoherent, or logically inconsistent, or impossible, or inconsistent with known fact, of improbable given known fact, or morally repugnant, or the like. Second, there are indirect arguments for atheism: direct arguments for something that entails atheism. Third, there are comparative arguments for atheism: e.g., arguments for the view that (atheistic) naturalism (...) is more theoretically virtuous than theism. (shrink)

This paper outlines an argument for atheism from naturalism that I have developed in more detail elsewhere (in particular, in *The Best Argument against God*). The overall shape of the argument is as follows: first, naturalism is simpler than theism; second, there is no data that naturalism does not explain at least as well as theism; and, third, naturalism entails atheism; so we have good reason to prefer atheism to theism. Note that this statement of the shape (...) of the argument is NOT a statement of the argument itself. (shrink)

In this article, I will discuss some of the arguments for and against the existence of God, in particular the monotheistic God believed in the Abramahamic religions (Judiasm, Islam, and Christianity) as well as Babism, the Bahai Faith, and Sikhism. Arguments for the existence of God try to argue that either God exists (based on other things people agree with) or that belief in God is reasonable. Arguments against the existence of God try to argue that the (...) existence of God leads to some contradiction or other absurdity. (shrink)

A popular introduction to common consent arguments for belief in God.

A number of theistic philosophers have recently denied that God is subject to moral and rational norms. At the same time, many theists employ epistemological and inductive arguments for the existence of God. I will argue that ‘no-norms’ theists cannot make use of such arguments: if God is not subject to norms – particularly rational norms – then we can say nothing substantive about what kind of worlds God would be likely to create, and as such, we cannot (...) predict the likelihood of any particular evidence given theism. What is more, I argue that this lack of constraint on God's creative act raises a serious sceptical challenge for no-norms theism. (shrink)

Preprinted in God and the Problem of Evil(Blackwell 2001), ed. William Rowe. Many people deny that evil makes belief in atheism more reasonable for us than belief in theism. After all, they say, the grounds for belief in God are much better than the evidence for atheism, including the evidence provided by evil. We will not join their ranks on this occasion. Rather, we wish to consider the proposition that, setting aside grounds for belief in God and relying only (...) on the background knowledge shared in common by nontheists and theists, evil makes belief in atheism more reasonable for us than belief in theism. Our aim is to argue against this proposition. We recognize that in doing so, we face a formidable challenge. It’s one thing to say that evil presents a reason for atheism that is, ultimately, overridden by arguments for theism. It’s another to say that it doesn’t so much as provide us with a reason for atheism in the first place. In order to make this latter claim seem initially more plausible, consider the apparent design of the mammalian eye or the apparent fine-tuning of the universe to support life. These are often proposed as reasons to believe in theism. Critics commonly argue not merely that these supposed reasons for theism are overridden by arguments for atheism but rather that they aren’t good reasons for theism in the first place. Our parallel proposal with respect to evil and atheism is, initially at least, no less plausible than this proposal with respect to apparent design and theism. (shrink)

In this article I outline two epistemological theistic arguments. The first one starts from the dilemma between our strong conviction that we possess some knowledge of the world and the belief that there are some serious reasons which undermine it. In my opinion theism opens the possibility of the way out of the dilemma. The second argument depends on the premise that in every time every worldly thing is actually perceived or known. I support it by four considerations (...) and claim that the simplest explanation of the epistemic ‘non-loneliness’ of the world is the existence of the Supreme Cogniser. (shrink)

Alvin Plantinga’s religious epistemology has been used to respond to many debunking arguments against theistic belief. However, critics have claimed that Plantinga’s religious epistemology conflicts with skeptical theism, a view often used in response to the problem of evil. If they are correct, then a common way of responding to debunking arguments conflicts with a common way of responding to the problem of evil. In this paper, I examine the critics’ claims and argue that they are right. (...) I then present two revised versions of Plantinga’s argument for his religious epistemology. I call the first a 'religion-based argument' and the second an 'intention-based argument'. Both are compatible with skeptical theism, and both can be used to respond to debunking arguments. They apply only to theistic beliefs of actual persons who have what I call 'doxastically valuable relationships' with God – valuable relationships the goods of which entail the belief that God exists. (shrink)

Dennis Whitcomb argues that there is no God on the grounds that God is supposed to be omniscient, yet nothing could be omniscient due to the nature of grounding. We give a formally identical argument that concludes that one of the present co-authors does not exist. Since he does exist, Whitcomb’s argument is unsound. But why is it unsound? That is a difficult question. We venture two answers. First, one of the grounding principles that the argument relies on is false. (...) Second, the argument equivocates between two kinds of grounding: instance-grounding and quasi-mereological grounding. Happily, the equivocation can be avoided; unhappily, avoidance comes at the price of a false premise. (shrink)

This paper is an English version of the paper that was published in German under the title: "Über die Aussichten erfolgreicher Beweise für Theismus oder Atheismus". My English paper was translated into German by Gabriele Schlegel. -/- The aim of this paper is to examine the prospects for proofs or successful arguments for the existence or non-existence of God.

Numerous supposed immoral mandates and commands by God found in religious texts are introduced and discussed. Such passages are used to construct a logical contradiction contention that is called the moral epistemological argument. It is shown how there is a contradiction in that God is omnibenevolent, God can instruct human beings, and God at times provides us with unethical orders and laws. Given the existence of the contradiction, it is argued that an omnibenevolent God does not exist. Finally, this contention (...) is defended from several objections. (shrink)

There are at least two kinds of design arguments for theism: fine-tuning arguments and biological design arguments. Dougherty and Poston (2008) have argued that the success of one requires the failure of the other, and vice versa. The reason is that the success of these arguments hinges on the following crucial probability: the probability that biological life exists somewhere in the universe given that (a) our universe is finely tuned and that (b) biological development is (...) unguided by intelligence. According to Dougherty and Poston, fine-tuning arguments require that the crucial probability is high while biological design arguments require that the crucial probability is low. As a result, at most one of these design arguments can factor into a cumulative case argument for theism. I argue that this is mistaken. Specifically, I show that fine-tuning arguments can succeed even if the crucial probability is low. (shrink)

We raise various puzzles about the relationship between God and the meaning of life. These difficulties suggest that, even if we assume that God exists, and even if God’s existence would entail that our lives have meaning, God is not and could not be the source of the meaning of life. We conclude by discussing implications of our arguments: these claims can be used in a novel argument for atheism; these claims undermine an extant argument for God’s existence; and (...) they suggest that atheism is consistent with our lives having meaning. (shrink)

It can be easy to assume that since the “theist in the street” is unaware of any of the traditional arguments for theism, he or she is not in position to offer independent rational support for believing that God exists. I argue that that is false if we accept with William Alston that “manifestation beliefs” can enjoy rational support on the basis of suitable religious experiences. I make my case by defending the viability of a Moorean-style proof for (...) theism—a proof for the existence of God that parallels in structure G. E. Moore’s famous proof for the existence of the external world. I argue that this shows that even if the theist in the street has nothing to offer for helping to convince the religious sceptic, this needn’t entail that she cannot offer independent rational support in defense of her theistic belief. (shrink)

Humean arguments from evil are some of the most powerful arguments against Theism. They take as their data what we know about good and evil. And they argue that some rival to Theism better explains, or otherwise predicts, that data than Theism. However, this paper argues that there are many problems with various methods for defending Humean arguments. I consider Philo’s original strategy; modern strategies in terms of epistemic probability; phenomenological strategies; and strategies that (...) appeal to scientific and metaphysical explanations. None of these methods have been sufficiently developed to provide a clear and distinctive defense of Humean arguments. Defenders of Humean arguments need to spend more time on the underlying methodology of their arguments. (shrink)

We argue that there is a conflict among classical theism's commitments to divine simplicity, divine creative freedom, and omniscience. We start by defining key terms for the debate related to classical theism. Then we articulate a new argument, the Aloneness Argument, aiming to establish a conflict among these attributes. In broad outline, the argument proceeds as follows. Under classical theism, it's possible that God exists without anything apart from Him. Any knowledge God has in such a world (...) would be wholly intrinsic. But there are contingent truths in every world, including the world in which God exists alone. So, it's possible that God contingently has wholly intrinsic knowledge. But whatever is contingent and wholly intrinsic is an accident. So, God possibly has an accident. This is incompatible with classical theism. Finally, we consider and rebut several objections. (shrink)

Skeptical theism is a popular response to arguments from evil. Many hold that it undermines a key inference often used by such arguments. However, the case for skeptical theism is often kept at an intuitive level: no one has offered an explicit argument for the truth of skeptical theism. In this article, I aim to remedy this situation: I construct an explicit, rigorous argument for the truth of skeptical theism.

Among the things that students of the problem of evil think about is whether explanatory versions of the evidential argument from evil are better than others, better than William Rowe’s famous versions of the evidential argument, for example. Some of these students claim that the former are better than the latter in no small part because the former, unlike the latter, avoid the sorts of worries raised by so-called “skeptical theists”. Indeed, Trent Dougherty claims to have constructed an explanatory version (...) that is “fundamentally immune to considerations pertaining to skeptical theism”. I argue that he has done no such thing. (shrink)

This paper is an attempt to improve the practical argument for beliefs in God. Some theists, most famously Kant and William James, called our attention to a particular set of beliefs, the Jamesian-type beliefs, which are justified by virtue of their practical significance, and these theists tried to justify theistic beliefs on the exact same ground. I argue, contra the Jamesian tradition, that theistic beliefs are different from the Jamesian-type beliefs and thus cannot be justified on the same ground. I (...) also argue that the practical argument, as it stands, faces a problem of self-defeat. I then construct a new practical argument that avoids both problems. According to this new argument, theistic beliefs are rational to accept because such beliefs best supply us with motivation strong enough to carry out demanding moral tasks. (shrink)

Critics of skeptical theism often claim that if it (skeptical theism) is true, then we are in the dark about whether (or for all we know) there is a morally justifying for God to radically deceive us. From here, it is argued that radical skepticism follows: if we are truly in the dark about whether there is a morally justifying reason for God to radically deceive us, then we cannot know anything. In this article, I show that skeptical (...) theism does not entail that we are in the dark about whether (or for all we know) there is a morally justifying reason for God to deceive us. And hence arguments against skeptical theism that make use of this assumption fail. (shrink)

This paper considers whether theism is compatible with moral error theory. This issue is neglected, perhaps because it is widely assumed that these views are incompatible. I argue that this is mistaken. In so doing, I articulate the best argument for thinking that theism and moral error theory are incompatible. According to it, these views are incompatible because theism entails that God is morally good, and moral error theory entails that God is not. I reject this argument. (...) Since it is the best argument for thinking that theism and moral error theory are incompatible, I conclude that these views are compatible: one can coherently accept both views. (shrink)

Following Hume’s lead, Paul Draper argues that, given the biological role played by both pain and pleasure in goal-directed organic systems, the observed facts about pain and pleasure in the world are antecedently much more likely on the Hypothesis of Indifference than on theism. I examine one by one Draper’s arguments for this claim and show how they miss the mark.

In this chapter, I consider personal and impersonal anti-theism and personal and impersonal pro-theism. I show that skeptical theism undermines arguments for personal anti-theism and impersonal anti-theism. Next, I show that (at least some) arguments for personal and impersonal pro-theism are not undermined by skeptical theism. This throws a wrench in debates about the axiology of theism: if skeptical theism is true, then it is very difficult to establish certain (...) positions in answer to the axiological question about God. (shrink)

I discuss Richard Swinburne’s account of religious experience in his probabilistic case for theism. I argue, pace Swinburne, that even if cosmological considerations render theism not too improbable, religious experience does not render it more probable than not.

In this paper, I will explain and motivate the common consent argument for theism. According to the common consent argument it is rational for you to believe that God exists because you know so many other people believe that God exists. Having motivated the argument, I will explain and motivate several pressing objections to the argument and evaluate their probative force. The paper will serve as both an accessible introduction to this argument as well as a resource for continued (...) research on the topic. (shrink)

Inductive arguments from evil claim that evil presents evidence against the existence of God. Skeptical theists hold that some such arguments from evil evince undue confidence in our familiarity with the sphere of possible goods and the entailments that obtain between that sphere and God’s permission of evil. I argue that the skeptical theist’s skepticism on this point is inconsistent with affirming the truth of a given theodicy. Since the skeptical theist’s skepticism is best understood dialogically, I’ll begin (...) by sketching the kind of argument against which the skeptical theist’s skepticism is pitched. I will then define ‘skeptical theistic skepticism’, offer a precise definition of ‘theodicy’, and proceed with my argument. (shrink)

Perfect being theism is the view that the perfect being exists and the property being-perfect is the property being-God. According to the strong analysis of perfection, a being is perfect just in case it exemplifies all perfections. On the other hand, the weak analysis of perfection claims that a being is perfect just in case it exemplifies the best possible combination of compatible perfections. Strong perfect being theism accepts the former analysis while weak perfect being theism accepts (...) the latter. In this paper, I argue that there are good reasons to reject both versions of perfect being theism. On the one hand, strong perfect being theism is false if there are incompatible perfections; I argue that there are. On the other hand, if either no comparison can be made between sets of perfections, or they are equally good, then there is no best possible set of perfections. I argue for the antecedent of this conditional statement, concluding that weak perfect being theism is false. In the absence of other analyses of perfection, I conclude that we have reason to reject perfect being theism. (shrink)

Skeptical theism is a family of responses to the evidential problem of evil. What unifies this family is two general claims. First, that even if God were to exist, we shouldn’t expect to see God’s reasons for permitting the suffering we observe. Second, the previous claim entails the failure of a variety of arguments from evil against the existence of God. In this essay, we identify three particular articulations of skeptical theism—three different ways of “filling in” those (...) two claims—and describes their role in responding to evidential arguments of evil due to William Rowe and Paul Draper. But skeptical theism has been subject to a variety of criticisms, several of which raise interesting issues and puzzles not just in philosophy of religion but other areas of philosophy as well. Consequently, we discuss some of these criticisms, partly with an eye to bringing out the connections between skeptical theism and current topics in mainstream philosophy. Finally, we conclude by situating skeptical theism within our own distinctive methodology for evaluating world views, what we call “worldview theory versioning.”. (shrink)

Enric F. Gel has recently argued that classical theism enjoys a significant advantage over Graham Oppy's naturalism. According to Gel, classical theism – unlike Oppy's naturalism – satisfactorily answers two questions: first, how many first causes are there, and second, why is it that number rather than another? In this article, I reply to Gel's argument for classical theism's advantage over Oppy's naturalism. I also draw out wider implications of my investigation for the gap problem and Christian (...) doctrine along the way. (shrink)

Does theism make a difference to whether there are moral facts? In this paper I suggest that, despite how much uptake this question gets in philosophical literature, it is not well formed. “Theism” leaves too indeterminate what God is like for us to discern what difference God’s existence would make to moral facts. Arguments like the explanans-driven argument for theistic moral realism and the explanationist argument for naturalist moral realism both require extra substantive assumptions about God in (...) order to be valid and compelling. Specifically, the arguments must take a stand on whether God is personal or a-personal, and how this affects God’s relation to the natural world. (shrink)

Skeptical theism (ST) may undercut the key inference in the evidential argument from evil, but it does so at a cost. If ST is true, then we lose our ability to assess the all things considered (ATC) value of natural events and states of affairs. And if we lose that ability, a whole slew of undesirable consequences follow. So goes a common consequential critique of ST. In a recent article, Anderson has argued that this consequential critique is flawed. Anderson (...) claims that ST only has the consequence that we lack epistemic access to potentially God-justifying reasons for permitting a prima facie “bad” (or “evil”) event. But this is very different from lacking epistemic access to the ATC value of such events. God could have an (unknowable) reason for not intervening to prevent E and yet E could still be (knowably) ATC-bad. Ingenious though it is, this article argues that Anderson’s attempted defence of ST is flawed. This is for two reasons. First, and most importantly, the consequential critique does not rely on the questionable assumption he identifies. Indeed, the argument can be made quite easily by relying purely on Anderson’s distinction between God-justifying reasons for permitting E and the ATC value of E. And second, Anderson’s defence of his position, if correct, would serve to undermine the foundations of ST. (shrink)

Several theists, including Linda Zagzebski, have claimed that theism is somehow committed to nonvacuism about counterpossibles. Even though Zagzebski herself has rejected vacuism, she has offered an argument in favour of it, which Edward Wierenga has defended as providing strong support for vacuism that is independent of the orthodox semantics for counterfactuals, mainly developed by David Lewis and Robert Stalnaker. In this paper I show that argument to be sound only relative to the orthodox semantics, which entails vacuism, and (...) give an example of a semantics for counterfactuals countenancing impossible worlds for which it fails. (shrink)

I examine issues in the philosophy of religion at the intersection of what possibilities there are and what a God, as classically conceived in the theistic philosophical tradition, would be able to do. The discussion is centered around arguing for an incompatibility between theism and two principles about possibility and ability, and exploring what theists should say about these incompatibilities. -/- I argue that theism entails that certain kinds and amounts of evil are impossible. This puts theism (...) in conflict with popular principles of modal recombination. However, theists have plausible explanations for the violations of recombination that they posit, and can suitably amend these principles without giving up their usefulness in accounting for what possibilities there are. -/- I also argue that despite the impossibility of these evils, God is able to bring these evils about. This puts theism in conflict with the principle that no one is able to do the impossible. However, theists can give a plausible account of why God is unique in being able to do the impossible, and have distinctive resources to address the arguments in favor of the idea that no one is able to do the impossible. And by denying this principle, theists are able to resolve several otherwise difficult puzzles, including reconciling conflicts between the divine attributes. (shrink)

This paper is a response to an earlier paper by Mark Nelson in which he argues for the claim that the best judges of the merits of arguments for the existence of God are theists whose belief in God is properly basic. I criticise Nelson's argument, and pursue some questions about the significance of the conclusion for which he argues.

Sceptical theists undermine the argument from evil by claiming that our ability to distinguish between justified and unjustified evil is weak enough that we must take seriously the possibility that all evil is justified. However, I argue that this claim leads to a dilemma: either our judgements regarding unjustified evil are reliable enough that the problem of evil remains a problem, or our judgements regarding unjustified evil are so unreliable that it would be misguided to use them in our decision-making. (...) The first horn undermines theism, while the second undermines our moral decision-making. Thus, sceptical theism is problematic. (shrink)

I will discuss some familiar problems in the philosophy of religion which arise for theistic belief. I will argue that it may be most worthwhile to focus on a particular sort of theistic belief, capital-T ’Theism’, central to which is a particular conception both of God and of the believer’s relation to God. At the heart of ’Theism’ in this sense is the continuing experience of God, both individual and collective. Compared with the evidence for Theistic belief that (...) is provided by this experiential contact with God, most of the usually considered arguments for and against God’s existence are secondary. (shrink)

This chapter provides an overview and critical discussion of cosmological arguments for theism, with special focus on the Kalam argument and arguments from contingency.

Famous examples of conceivability arguments include (i) Descartes’ argument for mind-body dualism, (ii) Kripke's ‘modal argument’ against psychophysical identity theory, (iii) Chalmers’ ‘zombie argument’ against materialism, and (iv) modal versions of the ontological argument for theism. In this paper, we show that for any such conceivability argument, C, there is a corresponding ‘mirror argument’, M. M is deductively valid and has a conclusion that contradicts C's conclusion. Hence, a proponent of C—henceforth, a ‘conceivabilist’—can be warranted in holding that (...) C's premises are conjointly true only if she can find fault with one of M's premises. But M's premises are modelled on a pair of C's premises. The same reasoning that supports the latter supports the former. For this reason, a conceivabilist can repudiate M's premises only on pain of severely undermining C's premises. We conclude on this basis that all conceivability arguments, including each of (i)–(iv), are fallacious. (shrink)

This paper is a reply to Robert Maydole’s “The Modal Perfection Argument for the Existence of a Supreme Being,” published in Philo 6, 2, 2003. I argue that Maydole’s Modal Perfection Argument fails, and that there is no evident way in which it can be repaired.

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)

Skeptical theism combines theism with skepticism about our capacity to discern God’s morally sufficient reasons for permitting evil. Proponents have claimed that skeptical theism defeats the evidential argument from evil. Many opponents have objected that it implies untenable moral skepticism, induces appalling moral paralysis, and the like. Recently Daniel Howard-Snyder has tried to rebut this prevalent objection to skeptical theism by rebutting it as an objection to the skeptical part of skeptical theism, which part he (...) labels “Agnosticism” (with an intentionally capital “A”). I argue that his rebuttal fails as a defense of Agnosticism against the objection and even more so as a defense of skeptical theism. (shrink)
