A number of authors have developed evidential arguments from evil in the past thirty years. Perhaps the best known evidential arguments from evil are those presented in Rowe (1979) and Draper (1989). We shall spend most of this chapter examining these two arguments.

In this paper we respond to criticisms by Michael Bergmann and Michael Rea in their “In Defense of Sceptical Theism : A Reply to Almeida and Oppy,” Australasian Journal of Philosophy 83.

This chapter discusses the two most prominent recent evidential arguments from evil, due, respectively, to William Rowe and Paul Draper. I argue that neither of these evidential arguments from evil is successful, i.e. such that it ought to persuade anyone who believes in God to give up that belief. In my view, theists can rationally maintain that each of these evidential arguments from evil contains at least one false premise.

Sceptical theists--e.g., William Alston and Michael Bergmann--have claimed that considerations concerning human cognitive limitations are alone sufficient to undermine evidential arguments from evil. We argue that, if the considerations deployed by sceptical theists are sufficient to undermine evidential arguments from evil, then those considerations are also sufficient to undermine inferences that play a crucial role in ordinary moral reasoning. If cogent, our argument suffices to discredit sceptical theist responses to evidential arguments from evil.

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)

Recent work on the evidential argument from evil offers us sundry considerations which are intended to weigh against this form of atheological arguments. By far the most provocative is that on a priori grounds alone, evil can be shown to be evidentially impotent. This astonishing thesis has been given a vigorous defense by Keith Yandell. In this paper, we shall measure the prospects for an a priori dismissal of evidential arguments from evil.

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)

I argue that Christian apophaticism provides the most powerful and economical response to the evidential argument from evil for the non-existence of God. I also reply to the objection that Christian apophaticism is incoherent, because it appears to entail the truth of the following contradiction: it is both possible and impossible to know God’s essential properties. To meet this objection, I outline a coherent account of the divine attributes inspired by the theology of the Greek Father’s and St. (...) Gregory Palamas. (shrink)

In his article, ‘What's Wrong with Tooley's Argument from Evil?’, Calum Miller's goal was to show that the evidential argument from evil that I have advanced is unsound, and in support of that claim, Miller set out three main objections. First, he argued that I had failed to recognize that the actual occurrence of an event can by itself, at least in principle, constitute good evidence that it was not morally wrong for God to allow events of (...) the kind in question. Miller's second objection was then that, in attempting to show that it is unlikely that God exists, I had failed to consider either positive arguments in support of the existence of God or possible theodicies, and thus that I was unjustified in drawing any conclusions concerning the probability that theism is true in the light of the total evidence available. Miller's third and final objection was that one of the approaches to logical probability that I employed – namely, that based upon a structure-description equiprobability principle, rather than a state-description equiprobability principle – was unsound since it has clearly unacceptable implications. In response, I argue that all three of Miller's objections are unsound. The third objection, however, is nevertheless important since it shows that my type of argument from evil cannot be based merely on the evils found in the world. One must also consider good states of affairs, and their relations to bad ones. I show, however, that that deficiency can be addressed in a completely satisfactory manner. (shrink)

This paper aims to neutralize Draper-style evidential arguments from evil by defending five theses: (1) that, when those who advance these arguments use the word “evil,” they are referring, at least in large part, to ill-being; (2) that well-being and ill-being come as a pair (i.e., are essentially related); (3) that well-being and ill-being are best understood in an at least partly objectivist way; (4) that (even partial) objectivism about well-being and ill-being is best understood as implying non-naturalism about (...) well-being and ill-being; and (5) that the truth of non-naturalism about well-being and ill-being does not fit cleanly with naturalism and, in fact, fits at least as well with theism as it does with naturalism.

White, Christensen, and Feldman have recently endorsed uniqueness, the thesis that given the same total evidence, two rational subjects cannot hold different views. Kelly, Schoenfield, and Meacham argue that White and others have at best only supported the weaker, merely intrapersonal view that, given the total evidence, there are no two views which a single rational agent could take. Here, we give a new argument for uniqueness, an argument with deliberate focus on the interpersonal element of the thesis. (...) Our argument is that the best explanation of the value of promoting rationality is an explanation that entails uniqueness. (shrink)

This chapter contains sections titled: Rowe's Evidential Argument from Evil Draper's Evidential Argument from Evil Concluding Remarks Works cited.

In this paper I offer an argument for the view that every body of evidence rationalizes exactly one doxastic attitude to each proposition. This is the uniqueness thesis. I do this by identifying a family of explanatory demands facing permissivists, those who deny the uniqueness thesis. Permissivists have traditionally motivated their view by attempting to identify counterexamples to the uniqueness thesis. But they have not developed a more general account of when permissive cases arise, and why. Permissivists cannot explain (...) why permissive cases are permissive, or how permissive they are. The paper contains three sections. First, I identify the explanatory demands facing the permissivist. Second, I survey a few existing proposals in the literature for how these explanatory demands might be answered, and argue that they fail. In the third section, I consider how permissivists might “soften” these explanatory demands, by holding that the permissible range of attitudes has vague borders, or that we do not know where its borders lie. I argue against both options. To do this, I present a general argument that there cannot be vague deontic facts, by appealing to a dominance principle and basic principles of deontic logic. If there are no deontic facts, then the permissible range of attitudes could not have vague borders, so the explanatory demands facing the permissivist remain unanswered. (shrink)

According to the ‘Evidential Internalists’, one’s evidence supervenes on one’s non-factive mental states. ‘Evidential Externalists’ deny that, and allow for external factors to determine what evidence one has. After clarifying what Evidential Internalism and Evidential Externalism entail, and what they are silent on, this chapter provides an opinionated overview of the main arguments and motivations behind Evidential Internalism and Evidential Externalism. It concludes that Evidential Externalism is a more promising view.

The setting of evidential standards is a core practice of scientific assessment for policy. Persuaded by considerations of inductive risk, philosophers generally agree that the justification of evidential standards must appeal to non-epistemic values but debate whether the balance of non-epistemic reasons favours varying evidential standards versus maintaining fixed high evidential standards in assessment, as both sets of standards promote different and important political virtues of advisory institutions. In this paper, I adjudicate the evidential standards (...) debate by developing a novel argument from justice, drawing on the IPCC’s assessment of climate impacts as a case study. I argue that in assessments marked by background evidential inequality, maintaining fixed high evidential standards results in an unequal distribution of ‘epistemic power’ among stakeholders, producing a ‘powerful assessment’ for the data-rich (a high rate of findings) and a ‘weak assessment’ for the data-poor (a low rate of findings). Where such inequalities of epistemic power disadvantage those in data-poor regions with respect to fundamental interests, such as basic human rights, we have decisive reasons of justice to vary evidential standards.

Evidential holism begins with something like the claim that “it is only jointly as a theory that scientific statements imply their observable consequences.” This is the holistic claim that Elliott Sober tells us is an “unexceptional observation”. But variations on this “unexceptional” claim feature as a premise in a series of controversial arguments for radical conclusions, such as that there is no analytic or synthetic distinction that the meaning of a sentence cannot be understood without understanding the whole language (...) of which it is a part and that all knowledge is empirical knowledge. This paper is a survey of what evidential holism is, how plausible it is, and what consequences it has. Section 1 will distinguish a range of different holistic claims, Sections 2 and 3 explore how well motivated they are and how they relate to one another, and Section 4 returns to the arguments listed above and uses the distinctions from the previous sections to identify holism's role in each case.

Evidentials indicate a source of evidence for a content, and sometimes do more. Depending on the language, they also express the speaker's belief in that content or its possibility. This paper is about how to explain the expression of belief. It argues that semantic explanations are better than illocutionary explanations in two ways. First, a general argument is provided that a semantic explanation is preferable. Second, a case study is given to the evidentials of Cuzco Quechua to argue that (...) a semantic explanation is preferable to the illocutionary explanation that has been proposed in great detail by Faller (2002, 2012, 2014). The upshot is that illocutionary explanations of how belief is expressed are dispensable for at least some languages with grammaticalized evidentials. (shrink)

In this paper, I respond to Frank Hofmann’s reply to my (2022) argument against “evidential minimalism” (EM). According to defenders of EM, there is a close connection between evidence and normative reasons for belief: evidence is either itself, or (under certain “minimal” conditions) gives rise to, a normative reason for belief. In my (2022), I argued against EM by showing that there are cases where: (i) S possesses strong evidence E for the truth of p at time t, (...) (ii) all minimal conditions for the normativity of E are met at t, (iii) S doesn’t believe p at t, yet (iv) S isn’t criticizable on account of (i)-(iii) at t. I then appealed to a linking claim connecting criticizability with the existence of normative reasons for belief. Hofmann’s reply invokes a distinction between two different kinds of epistemic criticism: a strong and a weak form. I will argue that Hofmann’s distinction fails to save EM from my argument.

This paper develops the idea that valid arguments are equivalent to true conditionals by combining Kripke’s theory of truth with the evidential account of conditionals offered by Crupi and Iacona. As will be shown, in a first-order language that contains a naïve truth predicate and a suitable conditional, one can define a validity predicate in accordance with the thesis that the inference from a conjunction of premises to a conclusion is valid when the corresponding conditional is true. The validity (...) predicate so defined significantly increases our expressive resources and provides a coherent formal treatment of paradoxical arguments. (shrink)

The primary aim of this chapter is to explain the nature of evidential reasoning, the characteristic difficulties encountered, and the tools to address these difficulties. Our focus is on evidential reasoning in criminal cases. There is an extensive scholarly literature on these topics, and it is a secondary aim of the chapter to provide readers the means to find their way in historical and ongoing debates.

This paper reassesses the case against Evidential Externalism, the thesis that one's evidence fails to supervene on one's non-factive mental states, focusing on two objections to Externalism due by Nicholas Silins: the armchair access argument and the supervenience argument. It also examines Silins's attempt to undermine the force of one major source of motivation for Externalism, namely that the rival Internalist picture of evidence is implicated in some central arguments for scepticism. While Silins concludes that the case (...) against Evidential Externalism is surprisingly strong, reassessing the arguments supports the opposite conclusion; the objections to Externalism are weak, and for all Silins has shown it may well have unmatched advantages when it comes to resisting scepticism.

Is it rational to believe that the mind is identical to the brain? Identity theorists say it is (or looks like it will be, once all the neuroscientific evidence is in), and they base this claim on a general epistemic route to belief in identity. I re-develop this general route and defend it against some objections. Then I discuss how rational belief in mind–brain identity, obtained via this route, can be threatened by an appropriately adjusted version of the anti-physicalist knowledge (...) argument. Responses to this threat usually appeal either to different modes of presentation or to phenomenal concepts. But neither type of response is satisfactory. I provide a novel response, which appeals to an innocuous epistemic peculiarity of phenomenal states, namely their, as I shall call it, evidential insulation. (shrink)

This paper defends David Hume's "Of Miracles" from John Earman's (2000) Bayesian attack by showing that Earman misrepresents Hume's argument against believing in miracles and misunderstands Hume's epistemology of probable belief. It argues, moreover, that Hume's account of evidence is fundamentally non-mathematical and thus cannot be properly represented in a Bayesian framework. Hume's account of probability is show to be consistent with a long and laudable tradition of evidential reasoning going back to ancient Roman law.

In the article, first I present the atheistic argument from pointless evil and the argument from chance. The essence of the argument from chance consists in the incompatibility of the existence of purposeless events and the existence of a God who planned the universe to the last detail. Second, I would like to show that there is a relation between the evidential argument from evil and the argument from chance. An analysis of the theistic (...) argument from small probabilities is a helpful starting point for the presentation of how the two arguments are related. (shrink)

Andy Egan has presented a dilemma for decision theory. As is well known, Newcomb cases appear to undermine the case for evidential decision theory. However, Egan has come up with a new scenario which poses difficulties for causal decision theory. I offer a simple solution to this dilemma in terms of a modified EDT. I propose an epistemological test: take some feature which is relevant to your evaluation of the scenarios under consideration, evidentially correlated with the actions under consideration (...) albeit, causally independent of them. Hold this feature fixed as a hypothesis. The test shows that, in Newcomb cases, EDT would mislead the agent. Where the test shows EDT to be misleading, I propose to use fictive conditional credences in the EDT-formula under the constraint that they are set to equal values. I then discuss Huw Price’s defence of EDT as an alternative to my diagnosis. I argue that my solution also applies if one accepts the main premisses of Price’s argument. I close with applying my solution to Nozick’s original Newcomb problem. (shrink)

This dissertation examines the dynamical dark matter problem in twentieth century astrophysics from the point of view of History and Philosophy of Science. The dynamical dark matter problem describes the situation astronomers find themselves in with regard to the dynamics of large scale astrophysical systems such as galaxies and galaxy clusters: The observed motions are incompatible with the visible distribution matter given the accepted law of gravitation. This discrepancy has two classes of possible solutions: either there exists copious amounts of (...) some kind of matter that neither emits nor absorbs radiation , or the law of gravitation must be revised. ;Chapter 2 describes the physical and philosophical foundations of dynamical inferences---inferences from discrepancies between well-founded theoretical expectations and reliable observations to the characteristics of candidate solutions. Chapter 3 discusses the history of dark matter . Chapter 4 reviews the present evidence bearing on the dark matter problem. Chapter 5 evaluates the important candidate matter solutions in light of the available evidence. Chapter 6 evaluates two candidate gravitational solutions on evidential and methodological grounds, and addresses the problem of theory choice. I do not try to solve the dark matter problem, but to uncover and evaluate patterns of inference involved in evidential arguments for and against candidate solutions. ;I show that Newton's "Reasoning from Phenomena" is a good framework from which to understand what is going on in this field. I argue that "higher order" and especially non-dynamical evidence is the best hope for solving this problem in dynamics. This is so in part because of "the dark matter double bind": the very existence of the dark matter problem means that we cannot be sure of the overall matter distribution in astrophysical systems, and this in turn means that the observed motions by themselves cannot provide relative confirmation of any theory of gravitational interactions taking place at these scales. I use Newton's Rules of Reasoning to argue that we should retain General Relativity as our theory of gravity at galactic and greater scales, despite the lack of positive evidence to confirm it over its rivals at these scales.

A handful of well-known arguments (the 'diachronic Dutch book arguments') rely upon theorems establishing that, in certain circumstances, you are immune from sure monetary loss (you are not 'diachronically Dutch bookable') if and only if you adopt the strategy of conditionalizing (or Jeffrey conditionalizing) on whatever evidence you happen to receive. These theorems require non-trivial assumptions about which evidence you might acquire---in the case of conditionalization, the assumption is that, if you might learn that e, then it is not the (...) case that you might learn something else that is consistent with e. These assumptions may not be relaxed. When they are, not only will non-(Jeffrey) conditionalizers be immune from diachronic Dutch bookability, but (Jeffrey) conditionalizers will themselves be diachronically Dutch bookable. I argue: 1) that there are epistemic situations in which these assumptions are violated; 2) that this reveals a conflict between the premise that susceptibility to sure monetary loss is irrational, on the one hand, and the view that rational belief revision is a function of your prior beliefs and the acquired evidence alone, on the other; and 3) that this inconsistency demonstrates that diachronic Dutch book arguments for (Jeffrey) conditionalization are invalid.

The problem of evil is broadly considered to be one of the greatest intellectual threats to traditional brands of theism. And William Rowe’s 1979 formulation of the problem in “The Problem of Evil and Some Varieties of Atheism” is the most cited formulation in the contemporary philosophical literature. In this paper, we explore how the tools and resources of experimental philosophy might be brought to bear on Rowe’s seminal formulation, arguing that our empirical findings raise significant questions regarding the ultimate (...) success of Rowe’s argument. Such a result would be quite notable within philosophy of religion, since this is considered one of the most formidable arguments against theism. However, further testing is needed before any firm conclusions can be drawn. -/- In section 1, we elucidate Rowe’s formulation of the problem of evil and the intuitions that seem to underwrite it. In section 2, we explore how the tools and resources of experimental philosophy might be brought to bear on Rowe’s formulation, outlining our hypotheses and our methods for testing them before showcasing our results. In section 3, we discuss the philosophical import of our results–arguing that our results, when taken together, pose an initial challenge to Rowe’s seminal argument. (shrink)

This paper explores an idea of Stoic descent that is largely neglected nowadays, the idea that an argument is valid when the conditional formed by the conjunction of its premises as antecedent and its conclusion as consequent is true. As it will be argued, once some basic features of our naıve understanding of validity are properly spelled out, and a suitable account of conditionals is adopted, the equivalence between valid arguments and true conditionals makes perfect sense. The account of (...) validity outlined here, which displays one coherent way to articulate the Stoic intuition, accords with standard formal treatments of deductive validity and encompasses an independently grounded characterization of inductive validity.

Some of the most interesting recent work in formal epistemology has focused on developing accuracy-based approaches to justifying Bayesian norms. These approaches are interesting not only because they offer new ways to justify these norms, but because they potentially offer a way to justify all of these norms by appeal to a single, attractive epistemic goal: having accurate beliefs. Recently, Easwaran & Fitelson (2012) have raised worries regarding whether such “all-accuracy” or “purely alethic” approaches can accommodate and justify evidential (...) Bayesian norms. In response, proponents of purely alethic approaches, such as Pettigrew (2013b) and Joyce (2016), have argued that scoring rule arguments provide us with compatible and purely alethic justifications for the traditional Bayesian norms, including evidential norms. In this paper I raise several challenges to this claim. First, I argue that many of the justifications these scoring rule arguments provide are not compatible. Second, I raise worries for the claim that these scoring rule arguments provide purely alethic justifications. Third, I turn to assess the more general question of whether purely alethic justifications for evidential norms are even possible, and argue that, without making some contentious assumptions, they are not. Fourth, I raise some further worries for the possibility of providing purely alethic justifications for content-sensitive evidential norms, like the Principal Principle. (shrink)

The very existence of society depends on the ability of its members to influence formatively the beliefs, desires, and actions of their fellows. In every sphere of social life, powerful human agents (whether individuals or institutions) tend to use coercion as a favorite shortcut to achieving their aims without taking into consideration the non-violent alternatives or the negative (unintended) consequences of their actions. This propensity for coercion is manifested in the doxastic sphere by attempts to shape people’s beliefs (and doubts) (...) while ignoring the essential characteristics of these doxastic states. I argue that evidential persuasion is a better route to influence people’s beliefs than doxastic coercion. Doxastic coercion perverts the belief-forming mechanism and undermines the epistemic and moral faculties both of coercers and coercees. It succeeds sporadically and on short-term. Moreover, its pseudo doxastic effects tend to disappear once the use of force ceases. In contrast to doxastic coercion, evidential persuasion produces lasting correct beliefs in accordance with proper standards of evidence. It helps people to reach the highest possible standards of rationality and morality. Evidential persuasion is based on the principles of symmetry and reciprocity in that it asks all persuaders to use for changing the beliefs of others only those means they used in forming their own beliefs respecting the freedom of will and assuming the standard of rationality. The arguments in favor of evidential persuasion have a firm theoretical basis that includes a conceptual clarification of the essential traits of beliefs. Belief is treated as a hypercomplex system governed by Leibniz’s law of continuity and the principle of self-organization. It appears to be a mixture consisting of a personal propositional attitude and physical objects and processes. The conceptual framework also includes a typology of believers according to the standards of evidence they assume. In this context, I present a weak version of Clifford’ ethical imperative. In the section dedicated to the prerequisites for changing beliefs, I show how doxastic agents can infuse premeditated or planned changes in the flow of endogenous changes in order to shape certain beliefs in certain desired forms. The possibility of changing some beliefs in a planned manner is correlated with a feedback doxastic (macro-mechanism) that produces a reaction when it is triggered by a stimulus. In relation with the two routes to influence beliefs, a response mechanism is worth taking into consideration – a mechanism governed to a significant extent by human conscience and human will, that appears to be complex, acquired, relatively detached from visceral or autonomic information processing, and highly variable in reactions. Knowing increasingly better this doxastic mechanism, we increase our chances to use evidential persuasion as an effective (although not time-efficient) method to mold people’s beliefs. (shrink)

This paper appeals to the phenomenon of dreaming to provide a novel defense against arguments from evil. The thrust of the argument is as follows: when we wake up after a nightmare we are often filled entirely with relief, and do not consider ourselves to have actually suffered very much at all; and since it is epistemically possible that this whole life is simply a dream, it follows that it is epistemically possible that in reality there is very little (...) suffering. This epistemic possibility decisively undermines a key premise of both logical and evidential arguments from evil. (shrink)

What is the relationship between faith and evidence? It is often claimed that faith requires going beyond evidence. In this paper, I reject this claim by showing how the moral demands to have faith warrant a person in maintaining faith in the face of counter-evidence, and by showing how the moral demands to have faith, and the moral constraints of evidentialism, are in clear tension with going beyond evidence. In arguing for these views, I develop a taxonomy of different ways (...) of irrationally going beyond evidence and contrast this with rational ways of going against evidence. I then defend instances of having a moral demand to have faith, explore how this stands in tension with going beyond and against evidence, and develop an argument for the claim that faith involves a disposition to go against, but not beyond evidence.

Peter Achinstein has argued at length and on many occasions that the view according to which evidential support is defined in terms of probability-raising faces serious counterexamples and, hence, should be abandoned. Proponents of the positive probabilistic relevance view have remained unconvinced. The debate seems to be in a deadlock. This paper is an attempt to move the debate forward and revisit some of the central claims within this debate. My conclusion here will be that while Achinstein may be (...) right that his counterexamples undermine probabilistic relevance views of what it is for e to be evidence that h, there is still room for a defence of a related probabilistic view about an increase in being supported, according to which, if p > p, then h is more supported given e than it is without e. My argument relies crucially on an insight from recent work on the linguistics of gradable adjectives. (shrink)

Many philosophers argue that Keynes’s concept of the “weight of arguments” is an important aspect of argument appraisal. The weight of an argument is the quantity of relevant evidence cited in the premises. However, this dimension of argumentation does not have a received method for formalisation. Kyburg has suggested a measure of weight that uses the degree of imprecision in his system of “Evidential Probability” to quantify weight. I develop and defend this approach to measuring weight. I (...) illustrate the usefulness of this measure by employing it to develop an answer to Popper’s Paradox of Ideal Evidence. (shrink)

Contemporary proponents of theodicy generally believe that a theodical reply to the evidential argument from evil must involve some appeal to the afterlife. In Richard Swinburne's writings on theodicy, however, we find two arguments that may be offered in opposition to this prevailing view. In this paper, these two arguments - the argument from usefulness and the argument from assumed consent - are explained and evaluated. It is suggested that both of these arguments are rendered ineffective (...) by their failure to distinguish between the different ways in which persons may be of-use in the attainment of some good state of affairs.

This paper defends a novel sceptical response to the fine-tuning argument for the existence of God (FTA). According to this response, even if FTA can establish, what I call, the confirmation proposition: ‘fine-tuning confirms the God hypothesis’, there is no reason to think that a strengthening of FTA can establish the evidence-favouring proposition: ‘fine-tuning favours the God hypothesis over its competitors’. My argument is that, any criteria for the explanation of fine-tuning that permit us to take the God (...) hypothesis seriously ought to make us sceptical that fine-tuning favours the God hypothesis over its competitors. As taking the God hypothesis seriously requires us to give a fair hearing to all sorts of non-theistic explanations, including the so-called weird sorts of atheism. (shrink)

In this paper, I propose that, in addition to the multiverse hypothesis, which is commonly taken to be an alternative explanation for fine-tuning, other than the design hypothesis, the simulation hypothesis is another explanation for fine-tuning. I then argue that the simulation hypothesis undercuts the alleged evidential connection between ‘designer’ and ‘supernatural designer of immense power and knowledge’ in much the same way that the multiverse hypothesis undercuts the alleged evidential connection between ‘fine-tuning’ and ‘fine-tuner’ (or ‘designer’). If (...) this is correct, then the fine-tuning argument is a weak argument for the existence of God. (shrink)

Presumption is a complex concept in law, affecting the dialogue setting. However, it is not clear how presumptions work in everyday argumentation, in which the concept of “plausible argumentation” seems to encompass all kinds of inferences. By analyzing the legal notion of presumption, it appears that this type of reasoning combines argument schemes with reasoning from ignorance. Presumptive reasoning can be considered a particular form of reasoning, which needs positive or negative evidence to carry a probative weight on the (...) conclusion. For this reason, presumptions shift the burden of providing evidence or explanations onto the interlocutor. The latter can provide new information or fail to do so: whereas in the first case the new information rebuts the presumption, in the second case, the absence of information that the interlocutor could reasonably provide strengthen the conclusion of the presumptive reasoning. In both cases the result of the presumption is to strengthen the conclusion of the reasoning from lack of evidence. As shown in the legal cases, the effect of presumption is to shift the burden of proof to the interlocutor; however, the shift a presumption effects is only the shift of the evidential burden, or the burden of completing the incomplete knowledge from which the conclusion was drawn. The burden of persuasion remains on the proponent of the presumption. On the contrary, reasoning from definition in law is a conclusive proof, and shifts to the other party the burden to prove the contrary. This crucial difference can be applied to everyday argumentation: natural arguments can be divided into dialectical and presumptive arguments, leading to conclusions materially different in strength. -/- .

The paper considers contemporary models of presumption in terms of their ability to contribute to a working theory of presumption for argumentation. Beginning with the Whatelian model, we consider its contemporary developments and alternatives, as proposed by Sidgwick, Kauffeld, Cronkhite, Rescher, Walton, Freeman, Ullmann-Margalit, and Hansen. Based on these accounts, we present a picture of presumptions characterized by their nature, function, foundation and force. On our account, presumption is a modal status that is attached to a claim and has the (...) effect of shifting, in a dialogue, a burden of proof set at a local level. Presumptions can be analysed and evaluated inferentially as components of rule-based structures. Presumptions are defeasible, and the force of a presumption is a function of its normative foundation. This picture seeks to provide a framework to guide the development of specific theories of presumption. (shrink)

Many have said that God is hidden. This alleged hiddenness is particularly troublesome for evangelical Christianity, much more so than generally recognized, for it would render certain facts about the world and about the Bible very hard to explain on the hypothesis that the God of evangelical Christianity exists. Those facts would be best explained by appeal to the alternate hypothesis that that deity does not exist. Three evidential, epistemic, atheological arguments emerge from this consideration. One of them is (...) the Argument from Nonbelief, which focuses on the fact that there is widespread nonbelief in the given deity. I have written essays and a book (NONBELIEF & EVIL) on that one. The other two are the Argument from Confusion (to be labeled AC) and the Argument from Biblical Defects (ABD). AC focuses on the fact that there is widespread confusion among Christians regarding important doctrinal issues, including morality and salvation. ABD focuses on the fact that there are various defects in the Bible. The present essay is devoted to the latter two arguments. (shrink)

One main goal of argumentation theory is to evaluate arguments and to determine whether they should be accepted or rejected. When there is no clear answer, a third option, being undecided, has to be taken into account. Indecision is often not considered explicitly, but rather taken to be a collection of all unclear or troubling cases. However, current philosophy makes a strong point for taking indecision itself to be a proper object of consideration. This paper aims at revealing parallels between (...) the findings concerning indecision in philosophy and the treatment of indecision in argumentation theory. By investigating what philosophical forms and norms of indecision are involved in argumentation theory, we can improve our understanding of the different uncertain evidential situations in argumentation theory.

"The Personal is Political": This was an often-heard slogan of feminist groups in the late sixties and early seventies. The slogan is no doubt open to many interpretations. There is one interpretation which touches on the epistemology of social facts, viz. the slogan claims that in assessing the features of a political system, personal experiences have privileged evidentiary value. For instancte, in the face of third person reports about political corruption, I may remain unmoved in my belief that the political (...) powers are morally upstanding, and it is only when I myself am adversely affected, that I come to change my views. There are two standard patterns of explanation of this type of belief formation: (i) We know that third-person reports may be lessreliable than first-person experiences; (ii) If the third-person reports are no less reliable than first-person experiences, we may just be dealing with a standard pattern of epistemic irrationality. However, we argue that there is also a much more surprising pattern of explanation: under certain conditions, a Bayesian argument can be proffered to the effect that it is rational to change one's beliefs in the face of personal experiences and not in the face of third-person reports, even if these experiences and reports are equally reliable. Hence, the feminist slogan (at least on one particular interpretation of it) receives unexpected support from Bayesian comers. We also show that this pattern of explanation has surprising repercussions on the question of the evidentiary value of miracles in philosophy of religion. (shrink)

I argue that Stephen Wykstra’s much discussed Parent Analogy is helpful in responding to the evidential problem of evil when it is expanded upon from a positive skeptical theist framework. This framework, defended by John Depoe, says that although we often remain in the dark about the first-order reasons that God allows particular instances of suffering, we can have positive second-order reasons that God would create a world with seemingly gratuitous evils. I respond to recent challenges to the Parent (...) Analogy by arguing that God, like a good parent, wants a rightly ordered relationship of mutual love with created beings. (shrink)

Noam Chomsky's Poverty of the Stimulus Argument is one of the most famous and controversial arguments in the study of language and the mind. Though widely endorsed by linguists, the argument has met with much resistance in philosophy. Unfortunately, philosophical critics have often failed to fully appreciate the power of the argument. In this paper, we provide a systematic presentation of the Poverty of the Stimulus Argument, clarifying its structure, content, and evidential base. We defend (...) the argument against a variety of philosophical criticisms, new and old, and argue that the Poverty of the Stimulus Argument continues to deserve its guiding role in the study of language and the mind.

John Maynard Keynes’s A Treatise on Probability is the seminal text for the logical interpretation of probability. According to his analysis, probabilities are evidential relations between a hypothesis and some evidence, just like the relations of deductive logic. While some philosophers had suggested similar ideas prior to Keynes, it was not until his Treatise that the logical interpretation of probability was advocated in a clear, systematic and rigorous way. I trace Keynes’s influence in the philosophy of probability through a (...) heterogeneous sample of thinkers who adopted his interpretation. This sample consists of Frederick C. Benenson, Roy Harrod, Donald C. Williams, Henry E. Kyburg and David Stove. The ideas of Keynes prove to be adaptable to their diverse theories of probability. My discussion indicates both the robustness of Keynes’s probability theory and the importance of its influence on the philosophers whom I describe. I also discuss the Problem of the Priors. I argue that none of those I discuss have obviously improved on Keynes’s theory with respect to this issue. (shrink)

The physicist Richard Gott defends the Copernican principle, which claims that when we have no information about our position along a given dimension among a group of observers, we should consider ourselves to be randomly located among those observers in respect to that dimension. First, I apply Copernican reasoning to the distribution of evil in the universe. I then contend that evidence for intelligent extraterrestrial life strengthens four important versions of the argument from evil. I remain neutral regarding whether (...) this result is a reductio of these arguments from evil or the statement of a genuine evidential relationship. (shrink)

This paper is concerned with the answer Wittgenstein gives to a specific version of the sceptical problem of other minds. The sceptic claims that the expressions of feelings and emotions can always be pretended. Wittgenstein contrasts this idea with two arguments. The first argument shows that other-ascriptions of psychological states are justified by experience of the satisfaction of criteria. The second argument shows that if one accepts the conclusion of the first argument, then one is compelled to (...) accept the idea that pretence is justifiably ascribed on the same evidential basis, which justifies any other-ascriptions. The two arguments show that other-ascriptions of psychological states and pretence-ascriptions share the same evidential basis. This allows Wittgenstein to say that the sceptic’s appeal to the possibility of pretence implies a contradiction. (shrink)

Those of us who enjoy certain products of the global industrial economy but also believe it is wrong to consume them are often so demoralized by the apparent inefficacy of our individual, private choices that we are unable to resist. Although he was a deontologist, Kant was clearly aware of this ‘consequent-dependent’ side of our moral psychology. One version of his ‘moral proof’ is designed to respond to the threat of such demoralization in pursuit of the Highest Good. That version (...) of the argument says that the capacity that faith and trust in God has to sustain our moral resolve licenses that faith and trust, from a practical point of view. My goal here is to argue that Kant’s proof has a contemporary, secular analogue in modern industrial contexts where the apparent “inefficacy” of an individual consumer’s choices in the face of massive insensitive supply-chains is a threat to her moral resolve. I conclude by suggesting that the Kantian approach may license us in adopting (as an item of defeasible moral faith) an evidential decision-theoretic principle regarding what it is to ‘make a difference.’ This in turn licenses trust -- if not in God then in other right-minded people.

What we call “the evidential argument from evil” is not one argument but a family of them, originating (perhaps) in the 1979 formulation of William Rowe. Wykstra’s early versions of skeptical theism emerged in response to Rowe’s evidential arguments. But what sufficed as a response to Rowe may not suffice against later more sophisticated versions of the problem of evil—in particular, those along the lines pioneered by Paul Draper. Our chief aim here is to make an (...) earlier version of skeptical theism more responsive to the type abductive atheology pioneered by Draper. In particular, we suggest a moderate form of skeptical theism may be able to resist Draper’s abductive atheology. (shrink)
