It seems obvious that when higher-order evidence makes it rational for one to doubt that one’s own belief on some matter is rational, this can undermine the rationality of that belief. This is known as higher-order defeat. However, despite its intuitive plausibility, it has proved puzzling how higher-order defeat works, exactly. To highlight two prominent sources of puzzlement, higher-order defeat seems to defy being understood in terms of conditionalization; and higher-order defeat can sometimes place agents in what seem like epistemic (...) dilemmas. This chapter draws attention to an overlooked aspect of higher-order defeat, namely that it can undermine the resilience of one’s beliefs. The notion of resilience was originally devised to understand how one should reflect the ‘weight’ of one’s evidence. But it can also be applied to understand how one should reflect one’s higher-order evidence. The idea is particularly useful for understanding cases where one’s higher-order evidence indicates that one has failed in correctly assessing the evidence, without indicating whether one has over- or underestimated the degree of evidential support for a proposition. But it is exactly in such cases that the puzzles of higher-order defeat seem most compelling. (shrink)

This Element examines what we can learn from religious disagreement, focusing on disagreement with possible selves and former selves, the epistemic significance of religious agreement, the problem of disagreements between religious experts, and the significance of philosophy of religion. Helen De Cruz shows how religious beliefs of others constitute significant higher-order evidence. At the same time, she advises that we should not necessarily become agnostic about all religious matters, because our cognitive background colors the way we evaluate evidence. This allows (...) us to maintain religious beliefs in many cases, while nevertheless taking the religious beliefs of others seriously. (shrink)

You shouldn’t have done it. But you did. Against your better judgment you scrolled to the end of an article concerning the state of race relations in America and you are now reading the comments. Amongst the slurs, the get-rich-quick schemes, and the threats of physical violence, there is one comment that catches your eye. Spencer argues that although it might be “unpopular” or “politically incorrect” to say this, the evidence supports believing that the black diner in his section will (...) tip poorly. He insists that the facts don’t lie. The facts aren’t racist. In denying his claim and in believing otherwise, it is you who engages in wishful thinking. It is you who believes against the evidence. You, not Spencer, are epistemically irrational. -/- My dissertation gives an account of the moral-epistemic norms governing belief that will help us answer Spencer and the challenge he poses. We live in a society that has been shaped by racist attitudes and institutions. Given the effects of structural racism, Spencer’s belief could have considerable evidential support. Spencer notes that it might make him unpopular, but he cares about the truth and he is willing to believe the unpopular thing. But, Spencer’s belief seems racist. Spencer asks, however, how could his belief be racist if his beliefs reflect reality and are rationally justified? Moreover, how could he wrong anyone by believing what he epistemically ought to believe given the evidence? In answer, I argue that beliefs can wrong. (shrink)

This paper seeks to widen the dialogue between the “epistemology of peer disagreement” and the epistemology informed by Wittgenstein’s last notebooks, later edited as On Certainty. The paper defends the following theses: not all certainties are groundless; many of them are beliefs; and they do not have a common essence. An epistemic peer need not share all of my certainties. Which response to a disagreement over a certainty is called for, depends on the type of certainty in question. Sometimes a (...) form of relativism is the right response. Reasonable, mutually recognized peer disagreement over a certainty is possible.—The paper thus addresses both interpretative and systematic issues. It uses Wittgenstein as a resource for thinking about peer disagreement over certainties. (shrink)

In this paper, I argue that the relationship between belief and credence is a central question in epistemology. This is because the belief-credence relationship has significant implications for a number of current epistemological issues. I focus on five controversies: permissivism, disagreement, pragmatic encroachment, doxastic voluntarism, and the relationship between doxastic attitudes and prudential rationality. I argue that each debate is constrained in particular ways, depending on whether the relevant attitude is belief or credence. This means that epistemologists should pay attention (...) to whether they are framing questions in terms of belief or in terms of credence and the success or failure of a reductionist project in the belief-credence realm has significant implications for epistemology generally.

We offer a critical survey of the most discussed accounts of epistemic peer disagreement that are found in the recent literature. We also sketch an alternative approach in line with a pluralist understanding of epistemic rationality.

Disagreement among experts is a central topic in social epistemology. What should an expert do when confronted with the different opinion of an epistemic peer? Possible answers include the steadfast view, the abstemious view, and moderate conciliatory views, which specify criteria for belief change when a peer’s different opinion is encountered. The practice of Delphi techniques in healthcare, medicine, and social sciences provides a real-life case study of expert disagreement, where disagreement is gradually transformed into consensus. An analysis of Delphi (...) shows that moderate conciliatory views are descriptively more adequate than rival views. However, it also casts doubt on whether the debate in social epistemology is explanatory relevant vis-à-vis real life cases of expert disagreement, where consensus replaces truth, and acceptance is more explanatorily relevant than belief.

While it seems hard to deny the epistemic significance of a disagreement with our acknowledged epistemic peers, there are certain disagreements, such as philosophical disagreements, which appear to be permissibly sustainable. These two claims, each independently plausible, are jointly puzzling. This paper argues for a solution to this puzzle. The main tenets of the solution are two. First, the peers ought to engage in a deliberative activity of discovering more about their epistemic position vis-à-vis the issue at stake. Secondly, the (...) peers are permitted to do so while entertaining a sui generis doxastic attitude of hypothesis. (shrink)

When should you engage with difficult arguments against your cherished controversial beliefs? The primary conclusion of this book is that your obligations to engage with counterarguments are more limited than is often thought. In some standard situations, you shouldn't engage with difficult counterarguments and, if you do, you shouldn't engage with them open-mindedly. This conclusion runs counter to aspects of the Millian political tradition and political liberalism, as well as what people working in informal logic tend to say about argumentation. (...) -/- Not all misleading arguments wear their flaws on their sleeve. Each step of a misleading argument might seem compelling and you might not be able to figure out what's wrong with it. Still, even if you can't figure out what's wrong with an argument, you can know that it's misleading. One way to know that an argument is misleading is, counterintuitively, to lack expertise in the methods and evidence-types employed by the argument. When you know that a counterargument is misleading, you shouldn't engage with it open-mindedly and sometimes shouldn't engage with it at all. You shouldn't engage open-mindedly because you shouldn't be willing to reduce your confidence in response to arguments you know are misleading. And you sometimes shouldn't engage closed-mindedly, because to do so can be manipulative or ineffective. -/- In making this case, Jeremy Fantl discusses echo chambers and group polarization, the importance in academic writing of a sympathetic case for the opposition, the epistemology of disagreement, the account of open-mindedness, and invitations to problematic academic speakers.

This chapter is a philosophical survey of some leading approaches in formal epistemology in the so-called ‘Bayesian’ tradition. According to them, a rational agent’s degrees of belief—credences—at a time are representable with probability functions. We also canvas various further putative ‘synchronic’ rationality norms on credences. We then consider ‘diachronic’ norms that are thought to constrain how credences should respond to evidence. We discuss some of the main lines of recent debate, and conclude with some prospects for future research.

Titelbaum Oxford studies in epistemology, 2015) has recently argued that the Enkratic Principle is incompatible with the view that rational belief is sensitive to higher-order defeat. That is to say, if it cannot be rational to have akratic beliefs of the form “p, but I shouldn’t believe that p,” then rational beliefs cannot be defeated by higher-order evidence, which indicates that they are irrational. In this paper, I distinguish two ways of understanding Titelbaum’s argument, and argue that neither version is (...) sound. The first version can be shown to rest on a subtle, but crucial, misconstrual of the Enkratic Principle. The second version can be resisted through careful consideration of cases of higher-order defeat. The upshot is that proponents of the Enkratic Principle are free to maintain that rational belief is sensitive to higher-order defeat. (shrink)

The epistemology of disagreement standardly divides conciliationist views from steadfast views. But both sorts of views are subject to counterexample—indeed, both sorts of views are subject to the same counterexample. After presenting this counterexample, I explore how the epistemology of disagreement should be reconceptualized in light of it.

The recent literature on the epistemology of disagreement focuses on the rational response question: how are you rationally required to respond to a doxastic disagreement with someone, especially with someone you take to be your epistemic peer? A doxastic disagreement with someone also confronts you with a slightly different question. This question, call it the epistemic trust question, is: how much should you trust our own epistemic faculties relative to the epistemic faculties of others? Answering the epistemic trust question is (...) important for the epistemology of disagreement because it sheds light on the rational response question. My main aim in this paper is to argue—against recent attempts to show otherwise—that epistemic self-trust does not provide a reason for remaining steadfast in doxastic disagreements with others. (shrink)

Arguments from disagreement against moral realism begin by calling attention to widespread, fundamental moral disagreement among a certain group of people. Then, some skeptical or anti-realist-friendly conclusion is drawn. Chapter 2 proposes that arguments from disagreement share a structure that makes them vulnerable to a single, powerful objection: they self-undermine. For each formulation of the argument from disagreement, at least one of its premises casts doubt either on itself or on one of the other premises. On reflection, this shouldn’t be (...) surprising. These arguments are intended to support very strong metaphysical or epistemological conclusions about morality. They must therefore employ very strong metaphysical or epistemological premises. But, given the pervasiveness of disagreement in philosophy, especially about metaphysics and epistemology, very strong premises are virtually certain to be the subject of widespread, intractable disagreement—precisely the sort of disagreement that proponents of these arguments think undermine moral claims. Thus, these arguments undermine their own premises. If Chapter 2’s argument is sound, it provides realists with a single, unified strategy for responding to any existing or forthcoming arguments from disagreement. (shrink)

Controversial view agnosticism is the thesis that we are rationally obligated to withhold judgment about a large portion of our beliefs in controversial subject areas, such as philosophy, religion, morality and politics. Given that one’s social identity is in no small part a function of one’s positive commitments in controversial areas, CVA has unsurprisingly been regarded as objectionably ‘spineless.’ That said, CVA seems like an unavoidable consequence of a prominent view in the epistemology of disagreement—conformism—according to which the rational response (...) to discovering that someone you identify as an epistemic peer or expert about p disagrees with you vis-à-vis p is to withhold judgment. This paper proposes a novel way to maintain the core conciliatory insight without devolving into an agnosticism that is objectionably spineless. The approach offered takes as a starting point the observation that–for reasons that will be made clear—the contemporary debate has bypassed the issue of the reasonableness of maintaining, rather than giving up, representational states weaker than belief in controversial areas. The new position developed and defended here explores this overlooked space; what results is a kind of controversial view. (shrink)

This article examines the central epistemological issues tied to the recognition of disagreement.

The question of the morality of abortion has long been the subject of intense, sometimes acrimonious debate. Even people within the same religious or philosophical tradition often disagree on the issue. For example, there are Christians who are “pro- choice” and there are Christians who are “pro-life.” Both sides marshal biblical, theological, and philosophical arguments in support of their positions. The substance of the abortion debate seems to reduce to one tricky question: when does personhood begin? Christian experts in various (...) fields, such as theology, biblical studies, ethics, and philosophy, have protracted disagreements over this question. In this article we will apply insights from the current literature on epistemic peer disagreement to the abortion issue. We will assume that there is only one correct answer to the abortion question. However, after making a crucial distinction between rationality as understood by internalists versus externalists, we will argue that there is more than one rational answer to the abortion question, since there is more than one rational way to weight evidence. We will conclude that, in a case of disagreement between two Christians who are epistemic peers with regards to the morality of abortion, both parties can be rational in adhering to their respective positions, but that this does not entail or even support ethical relativism.

The uniqueness thesis states that for any body of evidence and any proposition, there is at most one rational doxastic attitude that an epistemic agent can take toward that proposition. Permissivism is the denial of uniqueness. Perhaps the most popular form of permissivism is what I call the Epistemic Standard View, since it relies on the concept of epistemic standards. Roughly speaking, epistemic standards encode particular ways of responding to any possible body of evidence. Since different epistemic standards may rationalize (...) different doxastic states on the same body of evidence, this view gives us a form of permissivism if different agents can have different epistemic standards. Defenders of the ESV, however, have not paid sufficient attention to what it means to have a particular epistemic standard. I argue that any theory of epistemic standard possession must satisfy two criteria to adequately address the broader needs of the ESV. The first criterion is the normative criterion: a theory of standard-possession should explain why agents are rationally required to form beliefs in accordance with their own epistemic standard, rather than any other standard. The second criterion is the applicability criterion: a theory of standard-possession should rule that agents have the epistemic standards we intuitively think they have. I then argue that no extant theories of standard-possession can satisfy both these criteria. I conclude by diagnosing why these criteria are so hard to jointly satisfy. Defenders of the ESV are thus left with a serious obstacle to forming a complete and plausible version of their view. (shrink)

We present a minimal pragmatic restriction on the interpretation of the weights in the “Equal Weight View” regarding peer disagreement and show that the view cannot respect it. Based on this result we argue against the view. The restriction is the following one: if an agent, $$\hbox {i}$$ i, assigns an equal or higher weight to another agent, $$\hbox {j}$$ j,, he must be willing—in exchange for a positive and certain payment—to accept an offer to let a completely rational and (...) sympathetic $$\hbox {j}$$ j choose for him whether to accept a bet with positive expected utility. If $$\hbox {i}$$ i assigns a lower weight to $$\hbox {j}$$ j than to himself, he must not be willing to pay any positive price for letting $$\hbox {j}$$ j choose for him. Respecting the constraint entails, we show, that the impact of disagreement on one’s degree of belief is not independent of what the disagreement is discovered to be. (shrink)

The debate on the epistemology of disagreement has so far focused almost exclusively on cases of disagreement between individual persons. Yet, many social epistemologists agree that at least certain kinds of groups are equally capable of having beliefs that are open to epistemic evaluation. If so, we should expect a comprehensive epistemology of disagreement to accommodate cases of disagreement between group agents, such as juries, governments, companies, and the like. However, this raises a number of fundamental questions concerning what it (...) means for groups to be epistemic peers and to disagree with each other. In this paper, we explore what group peer disagreement amounts to given that we think of group belief in terms of List and Pettit’s ‘belief aggregation model’. We then discuss how the so-called ‘equal weight view’ of peer disagreement is best accommodated within this framework. The account that seems most promising to us says, roughly, that the parties to a group peer disagreement should adopt the belief that results from applying the most suitable belief aggregation function for the combined group on all members of the combined group. To motivate this view, we test it against various intuitive cases, derive some of its notable implications, and discuss how it relates to the equal weight view of individual peer disagreement.

Call the following claim Asymmetry: rationality often requires a more steadfast response to pure moral disagreement than it does to otherwise analogous non-moral disagreement. This paper briefly motivates Asymmetry and explores its implications for meta-ethics. Some philosophers have thought that anti-realists are better-placed than realists to explain Asymmetry because, if anti-realism is true, disagreement cannot provide evidence against the reliability of one's thinking about objective moral facts. This paper argues that this simple diagnosis fails to support otherwise plausible anti-realisms. It (...) closes by discussing an alternative explanation for Asymmetry, which appeals to the moral importance of steadfastness. (shrink)

Rob Lovering has recently argued that since theists have been unable, by means of philosophical arguments, to convince 85 percent of professional philosophers that God exists, at least one of their defining beliefs must be either false or meaningless. This paper is a critical examination of his argument. First we present Lovering’s argument and point out its salient features. Next we explain why the argument’s conclusion is entirely acceptable for theists, even if, as we show, there are multiple problems with (...) the premises. (shrink)

Consider two epistemic experts—for concreteness, let them be two weather forecasters. Suppose that you aren’t certain that they will issue identical forecasts, and you would like to proportion your degrees of belief to theirs in the following way: first, conditional on either’s forecast of rain being x, you’d like your own degree of belief in rain to be x. Secondly, conditional on them issuing different forecasts of rain, you’d like your own degree of belief in rain to be some weighted (...) average of the forecast of each. Finally, you’d like your degrees of belief to be given by an orthodox probability measure. Moderate ambitions, all. But you can’t always get what you want. (shrink)

Should we believe our controversial philosophical views? Recently, several authors have argued from broadly conciliationist premises that we should not. If they are right, we philosophers face a dilemma: If we believe our views, we are irrational. If we do not, we are not sincere in holding them. This paper offers a way out, proposing an attitude we can rationally take toward our views that can support sincerity of the appropriate sort. We should arrive at our views via a certain (...) sort of ‘insulated’ reasoning – that is, reasoning that involves setting aside certain higher-order worries, such as those provided by disagreement – when we investigate philosophical questions. (shrink)

This paper presents a challenge to conciliationist views of disagreement. I argue that conciliationists cannot satisfactorily explain why we need not revise our beliefs in response to certain moral disagreements. Conciliationists can attempt to meet this challenge in one of two ways. First, they can individuate disputes narrowly. This allows them to argue that we have dispute-independent reason to distrust our opponents’ moral judgment. This approach threatens to license objectionable dogmatism. It also inappropriately gives deep epistemic significance to superficial questions (...) about how to think about the subject matter of a dispute. Second, conciliationists can individuate disputes widely. This allows them to argue that we lack dispute-independent reason to trust our opponents’ moral judgment. But such arguments fail; our background of generally shared moral beliefs gives us good reason to trust the moral judgment of our opponents, even after we set quite a bit of our reasoning aside. On either approach, then, conciliationists should acknowledge that we have dispute-independent reason to trust the judgment of those who reject our moral beliefs. Given a conciliationist view of disagreement’s epistemic role, this has the unattractive result that we are epistemically required to revise some of our most intuitively secure moral beliefs. (shrink)

Disagreement among experts is a central topic in social epistemology. What should an expert do when confronted with the different opinion of an epistemic peer? Possible answers include the steadfast view (holding to one’s belief), the abstemious view (suspending one’s judgment), and moderate conciliatory views, which specify criteria for belief change when a peer’s different opinion is encountered. The practice of Delphi techniques in healthcare, medicine, and social sciences provides a real-life case study of expert disagreement, where disagreement is gradually (...) transformed into consensus. An analysis of Delphi shows that moderate conciliatory views are descriptively more adequate than rival views. However, it also casts doubt on whether the debate in social epistemology is explanatory relevant vis-à-vis real life cases of expert disagreement, where consensus replaces truth, and acceptance is more explanatorily relevant than belief.

This article is about the implications of a conciliatory view about the epistemology of peer disagreement for our moral beliefs. Many have endorsed a conciliatory view about the epistemology of peer disagreement according to which if we find ourselves in a disagreement about some matter with another whom we should judge to be our epistemic peer on that matter, we must revise our judgment about that matter. This article focuses on three issues about the implications of conciliationism for our moral (...) beliefs. The first is whether there is an asymmetry between the implications of conciliationism for the epistemic status of our moral beliefs and the implications of conciliationism for the epistemic status of our non-moral beliefs; for instance, some have argued that conciliationism leads to epistemological moral skepticism but not to epistemological nonmoral skepticism. The second is what the implications of conciliationism are for the epistemic status of particular moral beliefs. The third is whether conciliationism's impact on the epistemic status of our moral beliefs has practical implications. (shrink)

A familiar point in the literature on the epistemology of disagreement is that in the face of disagreement with a recognised epistemic peer the epistemically virtuous agent should adopt a stance of intellectual humility. That is, the virtuous agent should take a conciliatory stance and reduce her commitment to the proposition under dispute. In this paper, we ask the question of how such intellectual humility would manifest itself in a corresponding peer disagreement regarding knowledge-how. We argue that while it is (...) relatively straightforward to recast this debate in terms of a reductive intellectualist account of knowledge-how, whereby knowledge-how just is a matter of having a particular propositional attitude, the issue becomes more complex once we turn to anti-intellectualist positions. On these views, after all, such a disagreement won’t be just a matter of disagreeing about the truth of a proposition. Accordingly, to the extent that some kind of conciliation is plausibly required of the virtuous agent in the face of a recognised peer disagreement, this conciliation will not consist simply in belief revision. We propose a novel way to address this problem. We claim that what is required of the epistemically virtuous agent when confronted with peer disagreement regarding knowing how to φ is that thereafter she should be disposed to employ her way of φ-ing across a narrower range of practical circumstances than beforehand. Moreover, just as an agent needs to call on her intellectual virtues in order to determine the extent of conciliation required in an ordinary case of epistemic peer disagreement, so the intellectual virtues will play an important role in determining this shift in dispositions to φ that occurs as regards epistemic peer disagreement about knowledge-how.

Trent Dougherty argues (contra Jonathan Matheson) that when taking into consideration the probabilities involving skeptical theism (ST) and gratuitous evils, an agent may reasonably affirm both ST and that gratuitous evils exist. In other words, Dougherty thinks that assigning a greater than .5 probability to ST is insufficient to defeat the commonsense problem of evil. I argue that Dougherty’s response assumes, incorrectly, that ST functions solely as an evidential defeater, and that, when understood as a closure of inquiry defeater, ST (...) may still defeat reasonable belief in gratuitous evils, even in the face of strong evidence that gratuitous evils exist.

Epistemologists have shown increased interest in the epistemic significance of disagreement, and in particular, in whether there is a rational requirement concerning belief revision in the face of peer disagreement. This article examines some of the general issues discussed by epistemologists, and then considers how they may or may not apply to the case of religious disagreement, both within religious traditions and between religious (and non-religious) views.

An intuitive view regarding the epistemic significance of disagreement says that when epistemic peers disagree, they should suspend judgment. This abstemious view seems to embody a kind of detachment appropriate for rational beings; moreover, it seems to promote a kind of conciliatory inclination that makes for irenic and cooperative further discussion. Like many strategies for cooperation, however, the abstemious view creates opportunities for free-riding. In this essay, the authors argue that the believer who suspends judgment in the face of peer (...) disagreement is vulnerable to a kind of manipulation on the part of more tenacious peers. The result is that the abstemious view can have the effect of encouraging dogmatism. (shrink)

Current responses to the question of how one should adjust one’s beliefs in response to peer disagreement have, in general, formed a spectrum at one end of which sit the so-called ‘conciliatory’ views and whose other end is occupied by the ‘steadfast’ views. While the conciliatory views of disagreement maintain that one is required to make doxastic conciliation when faced with an epistemic peer who holds a different stance on a particular subject, the steadfast views allow us to maintain our (...) confidence in our relevant beliefs. My aim in this paper is not to adjudicate between these views. Rather, I shall focus on a particular strategy, namely, denying the appearance of epistemic symmetry between peers, that the steadfast views standardly invoke in support of their position. Having closely examined certain representative examples of the steadfast approach, I will argue that this strategy is fundamentally flawed. (shrink)

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)

Permissivism says that for some propositions and bodies of evidence, there is more than one rationally permissible doxastic attitude that can be taken towards that proposition given the evidence. Some critics of this view argue that it condones, as rationally acceptable, sets of attitudes that manifest an untenable kind of arbitrariness. I begin by providing a new and more detailed explication of what this alleged arbitrariness consists in. I then explain why Miriam Schoenfield’s prima facie promising attempt to answer the (...) Arbitrariness Objection, by appealing to the role of epistemic standards in rational belief formation, fails to resolve the problem. Schoenfield’s strategy is, however, a useful one, and I go on to explain how an alternative form of the standards-based approach to Permissivism – one that emphasizes the significance of the relationship between people’s cognitive abilities and the epistemic standards that they employ – can respond to the arbitrariness objection. (shrink)

An important principle in the epistemology of disagreement is Independence, which states, “In evaluating the epistemic credentials of another’s expressed belief about P, in order to determine how (or whether) to modify my own belief about P, I should do so in a way that doesn’t rely on the reasoning behind my initial belief about P” (Christensen 2011, 1-2). I present a series of new counterexamples to both Independence and also a revised, more widely applicable, version of it. I then (...) formulate and endorse a third version of Independence that avoids those counterexamples. Lastly, I show how this third version of Independence reveals two new ways one may remain steadfast in the face of two real life disagreements: one about God’s existence and one about moral realism.

In his influential discussion of the aim of belief, David Owens argues that any talk of such an ‘aim’ is at best metaphorical. In order for the ‘aim’ of belief to be a genuine aim, it must be weighable with other aims in deliberation, but Owens claims that this is impossible. In previous work, I have pointed out that if we look at a broader range of deliberative contexts involving belief, it becomes clear that the putative aim of belief is (...) capable of being weighed against other aims. Recently, however, Ema Sullivan-Bissett and Paul Noordhof have objected to this response on the grounds that it employs an undefended conception of the aim of belief not shared by Owens, and that it equivocates between importantly different contexts of doxastic deliberation. In this note, I argue that both of these objections fail. (shrink)

Permissivism about rationality is the view that there is sometimes more than one rational response to a given body of evidence. In this paper I discuss the relationship between permissivism, deference to rationality, and peer disagreement. I begin by arguing that—contrary to popular opinion—permissivism supports at least a moderate version of conciliationism. I then formulate a worry for permissivism. I show that, given a plausible principle of rational deference, permissive rationality seems to become unstable and to collapse into unique rationality. (...) I conclude with a formulation of a way out of this problem on behalf of the permissivist. (shrink)

Recently, Levinstein has offered two interesting arguments concerning epistemic norms and epistemic peer disagreement. In his first argument, Levinstein claims that a tension between Permissivism and steadfast attitudes in the face of epistemic peer disagreement generally leads us to conciliatory attitudes; in his second argument, he argues that, given an ‘extremely weak version of a deference principle,’ Permissivism collapses into Uniqueness. However, in this paper, I show that when we clearly distinguish among several types of Permissivism, Permissivism\, and Permissivism\), we (...) can see that any type of Permissivism fits well with steadfast attitudes. Further, even though Levinstein’s ‘extremely weak version of a deference principle’ does rule out a possibility for some types of Permissivism and Permissivism\), it is still compatible with the other type of Permissivism ), so we may regard at least that version of a deference principle as a viable position in connection with that particular type of permissive rationality. (shrink)

I present an argument against the thesis of Uniqueness and in favour of Permissivism. Counterexamples to Uniqueness are provided, based on ‘Safespot’ propositions – i.e. a proposition that is guaranteed to be true provided the subject adopts a certain attitude towards it. The argument relies on a plausible principle: (roughly stated) If S knows that her believing p would be a true belief, then it is rationally permitted for S to believe p. One motivation for denying this principle – viz. (...) opposition to ‘epistemic consequentialism’ – is briefly discussed. The principle is extended to cover degrees of belief and compared with a couple of other well-known constraints on rational degrees of belief. (shrink)

The purpose of this paper is to challenge what is often called the “Uniqueness” thesis. According to this thesis, given one’s total evidence, there is a unique rational doxastic attitude that one can take to any proposition. It is sensible for defenders of Uniqueness to commit to an accompanying principle that: when some agent A has equal epistemic reason both to believe that p and to believe that not p, the unique epistemically rational doxastic attitude for A to adopt with (...) respect to whether p is the suspension of judgment. In this paper, I offer a case wherein the agent has equal epistemic reason both to believe that p and to believe that not p, but the agent is not epistemically required to suspend judgment about whether p. Furthermore, the case is such that there seems to be no uniquely rational attitude for the agent to adopt. (shrink)

Conciliationism holds that disagreement of apparent epistemic peers often substantially undermines rational confidence in our opinions. Uniqueness principles say that there is at most one maximally rational doxastic response to any given batch of total evidence. The two views are often thought to be tightly connected. This paper distinguishes two ways of motivating conciliationism, and two ways that conciliationism may be undermined by permissive accounts of rationality. It shows how conciliationism can flourish under certain strongly permissive accounts of rationality. This (...) occurs when the motivation for conciliationism does not come from taking disagreement as evidence of one's own rational failings. However, divorcing the motive for conciliating from worries about rationality does not remove a feature of conciliationism that some find troubling: that conciliationism can lead to cases of “rational toxicity,” in which the most rational response to one's evidence involves violating some rational ideal.

There are several important arguments in metaethics that rely on explanatory considerations. Gilbert Harman has presented a challenge to the existence of moral facts that depends on the claim that the best explanation of our moral beliefs does not involve moral facts. The Reliability Challenge against moral realism depends on the claim that moral realism is incompatible with there being a satisfying explanation of our reliability about moral truths. The purpose of this chapter is to examine these and related arguments. (...) In particular, this chapter will discuss four kinds of arguments – Harman’s Challenge, evolutionary debunking arguments, irrelevant influence arguments, and the Reliability Challenge – understood as arguments against moral realism. The main goals of this chapter are (i) to articulate the strongest version of these arguments; (ii) to present and assess the central epistemological principles underlying these arguments; and (iii) to determine what a realist would have to do to adequately respond to these arguments.

In this article, I propose, defend, and apply a principle for applied ethics. According to this principle, we should exercise moral caution, at least when we can. More formally, the principle claims that if you should believe or suspend judgment that doing an action is a serious moral wrong, while knowing that not doing that action is not morally wrong, then you should not do that action. After motivating this principle, I argue that it has significant application in applied ethics. (...) The application to applied ethics comes by way of the epistemic significance of disagreement. Though such a principle has perhaps a number of applications in applied ethics, my focus here is limited to the question of whether it is morally permissible to eat animals for pleasure. (shrink)

How should one's beliefs be affected by one's knowing that other people, who are equally well-informed, rational, and intelligent – in other words, persons who are epistemic, or intellectual, peers – believe differently? In this thesis I look at a certain answer to this question. Richard Feldman argues that when two persons who have the same level of intelligence and who are equally well-informed disagree, the only rational response is for both persons to give up their disputed beliefs and suspend (...) judgment. I look at two objections to Feldman’s view, one from Ernest Sosa and the other from Thomas Kelly. In the end, I side with Feldman. Feldman’s call for suspension of judgment is based on an observation of symmetry in peer disagreements. Feldman argues that, in a peer disagreement, the participants should realize that for each thing one of them can say in support of his view, the other can say something analogous in support of the other view. This symmetry removes any rational basis to prefer one’s own view. I conclude that neither Sosa’s nor Kelly’s objections introduce any relevant asymmetries that would justify the disputants in a peer disagreement in sticking to their original beliefs. (shrink)

Two compelling principles, the Reasonable Range Principle and the Preservation of Irrelevant Evidence Principle, are necessary conditions that any response to peer disagreements ought to abide by. The Reasonable Range Principle maintains that a resolution to a peer disagreement should not fall outside the range of views expressed by the peers in their dispute, whereas the Preservation of Irrelevant Evidence Principle maintains that a resolution strategy should be able to preserve unanimous judgments of evidential irrelevance among the peers. No standard (...) Bayesian resolution strategy satisfies the PIE Principle, however, and we give a loss aversion argument in support of PIE and against Bayes. The theory of imprecise probability allows one to satisfy both principles, and we introduce the notion of a set-based credal judgment to frame and address a range of subtle issues that arise in peer disagreements.

We often hear such casual accusations: you just believe that because you are a liberal, a Christian, an American, a woman… When such charges are made they are meant to sting—not just emotionally, but epistemically. But should they? It can be disturbing to learn that one's beliefs reflect the influence of such irrelevant factors. The pervasiveness of such influence has led some to worry that we are not justified in many of our beliefs. That same pervasiveness has led others to (...) doubt whether there is any worry here at all. I argue that evidence of irrelevant belief influence is sometimes, but not always, undermining. My proposal picks out ordinary, non-skeptical cases in which we get evidence of error. It says that, in those cases, evidence of irrelevant influence is epistemically significant. It shows how respecting evidence of error is compatible with the epistemic lives we see ourselves living. We are fallible creatures, yes, but we are also capable and intelligent ones. We can recognize and correct for our own error so as to improve our imperfect, yet nevertheless robust, epistemic lives. (shrink)

This paper offers a new account of the epistemic significance of disagreement which is grounded in two assumptions; that knowledge is the norm of belief and, that the safety condition is a necessary condition for knowledge. These assumptions motivate a modal definition of epistemic peerhood, which is much easier to operate on than the more traditional definitions of epistemic peerhood. The modal account of the epistemic significance of disagreement yields plausible results regarding cases of disagreement. Furthermore, it is able to (...) tap into the intuitions that have motivated the conformist and the nonconformist positions and it locates a fruitful middle-ground between these two conflicting positions. It will be shown that the conformist is correct in that cases of real peer disagreement force us to suspend our judgment. The reason for this is that in cases of real peer disagreement our beliefs fail to be safe. The nonconformist, on the other hand, is right in that disagreement in itself does not have any epistemic power. It is only by the grace of nature that we gain knowledge. The fact that someone disagrees with you does not mean that you do not have knowledge. (shrink)
