Some philosophers working on the epistemology of disagreement claim that conciliationist responses to peer disagreement embody a kind of intellectual humility. Others contend that standing firm or “sticking to one’s guns” in the face of peer disagreement may stem from an admirable kind of courage or internal fortitude. In this paper, we report the results of two empirical studies that examine the relationship between conciliationist and steadfast responses to peer disagreement, on the one hand, and virtues such as intellectual humility, (...) courage, grit, and actively open-minded thinking, on the other. We observed positive correlations between measures of conciliationism, intellectual humility, and actively open-minded thinking but failed to find any reliable association between steadfastness, courage, and grit. Our studies reveal that there are at least two important intellectual virtues associated with conciliationist responses to peer disagreement (viz., intellectual humility and actively open-minded thinking) and two vices associated with steadfast responses (intellectual arrogance and myside bias). These findings shed new light on the overall epistemic goodness of the conciliationist perspective. -/- keywords: disagreement, conciliationism, steadfastness, intellectual humility, courage, actively open-minded thinking.

In this paper, I examine Thomas Kelly’s account of the epistemic significance of bias presented in Bias: A Philosophical Study. Kelly draws a parallel between the skeptical threat from bias and the skeptical threat from disagreement, and crafts a response to these skeptical threats. According to Kelly, someone who is not biased can rely on that fact to conclude that their disagreeing interlocutor is biased. Kelly motivates this response by drawing several parallels to recent lessons in epistemology: that some question-begging (...) reasoning is permissible, and that there are important asymmetries between epistemological good cases and bad cases. I argue that there are several reasons to resist Kelly’s response. In brief, there are problems with each of the motivations Kelly gives for his picture. Each parallel faces significant obstacles. In addition, his response also fails to take the new evil demon intuition seriously. (shrink)

The author defends Conciliationism as a response to peer-disagreement in ethics against a prominent objection: if in cases of peer-disagreement we have to move our credences towards those of our dissenting peers, then we have to adopt scepticism in fields where disagreement between peers abounds. For this objection, the case of ethics is particularly worrisome. The author argues that the objection from scepticism is based on a highly idealised notion of an epistemic peer. In cases of disagreement about ethical issues, (...) it is often unknown to us what another person counts as her evidence, since one’s notions of what counts as evidence and what weight to attach to different forms of evidence are impacted by one’s global outlook. Being aware of what an agent considers as evidence requires familiarity with that agent’s global outlook. This introduces two constraints on epistemic peerhood in cases of disagreement about ethics: an epistemic constraint, and a factual constraint. (shrink)

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.

Recently, more attention has been paid to the nature and value of the intellectual virtue of epistemic autonomy. One underexplored issue concerns how epistemic autonomy is related to other intellectual virtues. Plausibly, epistemic autonomy is closely related to a number of intellectual virtues like curiosity, inquisitiveness, intellectual perseverance, and intellectual courage to name just a few. Here, however, I will examine the relation between epistemic autonomy and intellectual humility. I will argue that epistemic autonomy and intellectual humility bear an interesting (...) relationship to one another in that they are interconnected and mutually supporting intellectual virtues. In sections 2 and 3 I will provide a brief overview of the predominant accounts of intellectual humility (section 2) and epistemic autonomy (section 3) in the literature. With an understanding of these intellectual virtues in hand, we will examine their relationship of mutual support in section 4. Section 5 will explore a challenge to this relationship coming from the epistemology of disagreement, and section 6 concludes. (shrink)

ABSTRACT The article starts out by introducing the phenomenon of basic disagreements among epistemic peers and arguing (...) that they are relevant and deserve attention. Secondly, it discusses the standard argument in favor of conciliationism. Finally, it holds that the typical reasons for conciliating do not apply to basic disagreements among peers, so that in these cases it is possible to be obstinate. (shrink)

It is fairly uncontroversial that when you encounter disagreement with some view of yours, you are often epistemically required to become at least somewhat less confident in that view. This includes political disagreements, where your level of confidence might in various ways affect your voting and other political behavior. But suppose that your opponents don’t comply with the epistemic norms governing disagreement – that is, they never reduce their confidence in their views in response to disagreement. If you always reduce (...) your confidence, but your opponents never reduce theirs – and everyone participates in the political process accordingly – then it seems like the deliberative process will be unfairly skewed in favor of your opponents. In this paper, I do two things. First, I try to explain how this can be so, even though the process by stipulation represents everyone’s beliefs equally. Second, I defend the view that in such cases, you should remedy the unfairness by voting out of accord with your beliefs. By introducing a distinct state that I call a “personal take,” which you can vote on the basis of in such a case, I explain how doing this need not be problematically insincere, nor incoherent from the inside. The discussion has a number of independent upshots for both democratic theory and the epistemology of disagreement. (shrink)

Unknown peers create a problem for those epistemologists who argue that we should be conciliatory in cases of peer disagreement. The standard interpretation of ‘being conciliatory’ has it that we should revise our opinions concerning a specific subject matter whenever we encounter someone who is as competent and well informed as we are concerning this subject matter (and thus is our peer) and holds a different opinion. As a consequence, peers whom we have never encountered and who are hence unknown (...) to us are not taken into account. This, however, appears odd; not only because it is an accidental matter which peers we happen to encounter and which not, but also because it would allow people to deliberately isolate themselves from any kind of intellectual exchange on the topic under consideration. The paper argues that we should take the problem of unknown peers seriously, and that disregarding the problem is an instance of the more general mistake of assuming that evidential quality and justified believability can be dealt with separately. Moreover, a solution to the problem of unknown peers is suggested. (shrink)

The paper argues that adopting a form of skepticism, Skeptical-Dogmatism, that recommends disbelieving each philosophical position in many multi-proposition disputes- disputes where there are three or more contrary philosophical views-leads to a higher ratio of true to false beliefs than the ratio of the “average philosopher”. Hence, Skeptical-Dogmatists have more accurate beliefs than the average philosopher. As a corollary, most philosophers would improve the accuracy of their beliefs if they adopted Skeptical-Dogmatism.

Central to many discussions of motivated reasoning is the idea that it runs afoul of epistemic normativity. Reasoning differently about information supporting our prior beliefs versus information contradicting those beliefs, is frequently equated with motivated irrationality. By analyzing the normative status of belief polarization, selective scrutiny, biased assimilation and the myside bias, I show this inference is often not adequately supported. Contrary to what’s often assumed, these phenomena need not indicate motivated irrationality, even though they are instances of belief-consistent information (...) processing. Second, I engage with arguments purporting to show that belief-consistent information processing does not indicate motivated irrationality because of its mere differential treatment of confirming and non-confirming evidence, but rather because it reveals the undermining presence of an irrelevant influence, such as a desire or partisan identity-driven cognition. While linking belief-consistent reasoning to a deeper source of directional motivation to make good on the claim that it indicates motivated irrationality is indeed what’s needed, two prominent such arguments fail. The non-normativity of many reasoning processes often taken to indicate motivated irrationality is not in fact well established. (shrink)

Political liberalism holds that political decisions should be made on the basis of public considerations, and not on the basis of comprehensive religious, moral, or philosophical views. An important objection to this view is that it presupposes doubt, hesitation, or skepticism about the truth of comprehensive doctrines on the side of reasonable citizens. Proponents of political liberalism, such as John Rawls and Jonathan Quong, successfully defend political liberalism against several objections of this kind. In this paper, I argue that recent (...) developments in the epistemology of disagreement require us to revisit these skeptical concerns. I will argue that the correct understanding of political liberalism’s epistemic commitments, in combination with a conciliatory view about peer disagreement, lead to a new skeptical problem for political liberalism. All reasonable citizens who also hold a set of religious, moral, or philosophical beliefs, I will argue, suffer from a breakdown of epistemic rationality. I will show that existing answers to skeptical objections fail to resolve this problem. (shrink)

The central question of the peer disagreement debate is: what should you believe about the disputed proposition if you have good reason to believe that an epistemic peer disagrees with you? This article shows that this question is ambiguous between evidential support (or propositional justification) and well-groundedness (or doxastic justification). The discussion focuses on conciliatory views, according to which peer disagreements require you to significantly revise your view or to suspend judgment. The article argues that for a wide range of (...) conceptions of evidential support, conciliatory views are false if they are understood entirely in terms of evidential support. Alternative conceptions of evidential support face some serious difficulties. These arguments speak against conciliationism, but the article then goes on to defend a conciliatory view about well-grounded belief: when you believe p, and you have good reason to believe that your epistemic peer disagrees with you, you are not justified in believing p because that belief is no longer well grounded. This picture of the epistemology of peer disagreement offers a reconciliation of some of the main competing views in the literature: conciliationism is true when we look at well-grounded belief, but a nonconciliatory view like Thomas Kelly's “total evidence view” is correct when we look at peer disagreement exclusively in terms of evidential support.

The debate on whether and why misinformation is bad primarily focuses on the spread of false beliefs as its main harm. From the assumption that misinformation primarily causes harm through the spread of false beliefs as a starting point, it has been contended that the problem of misinformation has been exaggerated. Its tendency to generate false beliefs appears to be limited. However, the near-exclusive focus on whether or not misinformation dupes people with false beliefs neglects other epistemic harms associated with (...) it. Specifically, I show that misinformation also causes trouble for the epistemic goods of truth attainment, intellectual autonomy and debate pluriformity. Moreover, for each of these goods, I argue that emphasizing error-avoidance exacerbates, rather than mitigates, the harms caused by misinformation. These oversights and dilemmas show that prioritizing error-avoidance in the fight against misinformation is not a neutral default policy or necessarily a net positive. A shift in focus away from the spread of false beliefs as the main harm of misinformation is needed to better understand and counter its negative effects. (shrink)

Standpoint epistemology is committed to the view that some epistemic advantage can be drawn from the position of powerlessness. Call this theepistemic privilege thesis. This thesis stands in need of explication and support. In providing that explication and support, I first distinguish between two readings of the thesis: the thesis that marginalized social locations confer some epistemic advantages (the epistemic advantage thesis) and the thesis that marginalized standpoints generate better, more accurate knowledge (the standpoint thesis). I then develop the former (...) by appealing to the notion of epistemic peers available in the disagreement literature. I next turn to the latter thesis, arguing that consciousness-raising plays an analogous role in the achievement of a standpoint as training does in the achievement of expertise. The upshot of this analysis is that it clarifies that while marginalization is necessary (though not sufficient) for epistemic advantage, it is neither necessary nor sufficient for epistemic privilege.

Responding to Cappelen and Dever’s claim that there is no distinctive role for perspectivality in epistemology, I argue that facts about the outcomes of one’s own reasoning processes may have a different evidential significance than facts about the outcomes of others’.

In this paper, I argue that the two most common views of how to respond rationally to peer disagreement–the Total Evidence View (TEV) and the Equal Weight View (EWV)–are both inadequate for substantial reasons. TEV does not issue the correct intuitive verdicts about a number of hypothetical cases of peer disagreement. The same is true for EWV. In addition, EWV does not give any explanation of what is rationally required of agents on the basis of sufficiently general epistemic principles. I (...) will then argue that there is a genuine alternative to both views–the Preemption View (PV)–that fares substantially better in both respects. I will give an outline and a detailed defense of PV in the paper. (shrink)

ABSTRACTShould conciliating with disagreeing peers be considered sufficient for reaching rational beliefs? Thomas Kelly argues that when taken this way, Conciliationism lets those who enter into a disagreement with an irrational belief reach a rational belief all too easily. Three kinds of responses defending Conciliationism are found in the literature. One response has it that conciliation is required only of agents who have a rational belief as they enter into a disagreement. This response yields a requirement that no one should (...) follow. If the need to conciliate applies only to already rational agents, then an agent must conciliate only when her peer is the one irrational. A second response views conciliation as merely necessary for having a rational belief. This alone does little to address the central question of what is rational to believe when facing a disagreeing peer. Attempts to develop the response either reduce to the first response, or deem necessary an unnecessary doxastic revision, or imply that rational dilemmas obtain in cases where intuitively there are none. A third response tells us to weigh what our pre-disagreement evidence supports against the evidence from the disagreement itself. This invites epistemic akrasia. (shrink)

The existence of deep and persistent moral disagreement poses a problem for a defender of moral knowledge. It seems particularly clear that a philosopher who thinks that we know a great many moral truths should explain how human populations have failed to converge on those truths. In this paper, I do two things. First, I show that the problem is more difficult than it is often taken to be, and second, I criticize a popular response, which involves claiming that many (...) false moral beliefs are the product of nonmoral ignorance. (shrink)

A number of authors have defended permissivism by appealing to rational supererogation, the thought that some doxastic states might be rationally permissible even though there are other, more rational beliefs available. If this is correct, then there are situations that allow for multiple rational doxastic responses, even if some of those responses are rationally suboptimal. In this paper, I will argue that this is the wrong approach to defending permissivism—there are no doxastic states that are rationally supererogatory. By the lights (...) of contemporary linguistics, ‘rational’ is an absolute gradable adjective, and as such, can only be applied to things that satisfy the top of the scale of rationality. For this reason, it is not possible to believe what is rational while also failing to believe what is rationally optimal. (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.

The aim of this paper is to describe a problem for calibrationism: a view about higher order evidence according to which one's credences should be calibrated to one's expected degree of reliability. Calibrationism is attractive, in part, because it explains our intuitive judgments, and provides a strong motivation for certain theories about higher order evidence and peer disagreement. However, I will argue that calibrationism faces a dilemma: There are two versions of the view one might adopt. The first version, I (...) argue, has the implausible consequence that, in a wide range of cases, calibrationism is the only constraint on rational belief. The second version, in addition to having some puzzling consequences, is unmotivated. At the end of the paper I sketch a possible solution. (shrink)

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)

The current debate about peer disagreement has so far mainly focused on the question of whether peer disagreements provide genuine counterevidence to which we should respond by revising our credences. By contrast, comparatively little attention has been devoted to the question by which process, if any, such revision should be brought about. The standard assumption is that we update our credences by conditionalizing on the evidence that peer disagreements provide. In this paper, we argue that non-dogmatist views have good reasons (...) to reject conditionalization. Instead, peer disagreements should be understood to call for a revision of our prior conditional probabilities: rather than merely adding to our original evidence, they pose a challenge to the thought that we have properly assessed the probative force of our original evidence. (shrink)

Does the epistemology of disagreement have significant consequences for theories of conceptual understanding? I argue that it does. I argue that the epistemology of disagreement manifests the existence of a special kind of concept, perspectival modes of metarepresentation, a kind of concept instances of which figure in the thinking about thoughts that occurs in deep disagreement. These perspectival modes of metarepresentation are de re modes of presentation of thoughts themselves – hence de re modes of metarepresentation – in which one (...) and the same thought is presented to higher‐order thinking about thoughts in different ways. These modes or ways are de re and perspectival because they are individuated by facts about whether the thought being thought about is the grasped or understood propositional object of one's own or another's thinking. I outline a broadly Fregean framework for theorizing conceptual understanding and draw out three significant consequences of the existence of perspectival modes of metarepresentation for theories of conceptual understanding: they (1) constitute a new philosophical motivation for a restricted fragment of what Terence Parsons calls a “libertine” hierarchy of Fregean sense; (2) provide, against David Chalmers, examples of a priori equivalences that are nevertheless cognitively significant; and (3) constitute a novel and pervasive example of Kripkean ‘Paderewski’‐type designators. (shrink)

Recently, philosophers have put forth views in the epistemology of disagreement that emphasize the epistemic relevance of the first-person perspective in disa- greement. In the first part of the paper, I attempt a rational reconstruction of these views. I construe these views as invoking the first-person perspective to explain why it is rational for parties to a disagreement to privilege their own opinions in the absence of independent explanations for doing so—to privilege without independent explanations. I reconstruct three ways privilege (...) might be thought to arise: by demotion, through self-trust, and through the epistemic immediacy in the first-person perspective. I argue that none of these ways, and none of the views that make use of them, clarify a compelling account of the epistemic relevance of the first-person perspective. In the second part of the paper, I try to discern some lessons and outline an alternative approach. According to this approach, the epistemic relevance of the first-person perspective is not to explain privilege without independent explanations but to explain the epistemic limits of intersubjective understanding. These limits are manifest in reflective disagreement and explain how other minds matter for one’s own mind in the pursuit of knowledge. The resulting view about the epistemology of disagreement is neither skeptical nor dogmatic, but dialectical, involving an active mental state that conceptualizes not only the subject matter but also one’s own and others’ minds in thinking and rational interaction at the epistemic limits of intersubjective understanding. (shrink)

‘Conciliationism’ is the view that disagreement with qualified disputants gives us a powerful reason for doubting our disputed views, a reason that will often be sufficient to defeat what would otherwise be strong evidential justification for our position. Conciliationism is disputed by many qualified philosophers, a fact that has led many to conclude that conciliationism is self-defeating. After examining one prominent response to this challenge and finding it wanting, I develop a fresh approach to the problem. I identify two levels (...) at which one may show epistemic deference—the level of one's credences and the level of one's reasoning—and show that in disagreements over conciliationism, deference at one level results in non-deference at the other. A commitment to epistemic deference therefore does not provide a rational reason to reduce confidence when conciliationism itself is disputed. After presenting the case for ‘resolute conciliationism’, I address two objections. (shrink)

I argue that the skeptical force of a disagreement is mitigated to the extent that it is fundamental, where a fundamental disagreement is one that is driven by differences in epistemic starting points. My argument has three steps. First, I argue that proponents of conciliatory policies have good reason to affirm a view that I call “instrumentalism,” a view that commends treating our doxastic inclinations like instrumental readouts. Second, I show that instrumentalism supplies a basis for demanding conciliatory requirements in (...) superficial disagreements but not in fundamental disagreements. Third, I argue that the frequently invoked “independence” principle, which arguably would require significant conciliation in fundamental disputes, is unmotivated in light of the explanatory power of instrumentalism. The most plausible conciliatory view, then, is a weak conciliationism that features instrumentalism rather than independence as the central principle, and that therefore gives us a principled basis for thinking that fundamental disagreements should occasion less doxastic revision than shallow disagreements. (shrink)

Alex Worsnip has recently argued against conciliatory views that say that the degree of doxastic revision required in light of disagreement is a function of one’s antecedent reliability estimates for oneself and one’s disputant. According to Worsnip, the degree of doxastic revision is also sensitive to the resilience of these estimates; in particular, when one has positive “net resilience,” meaning that one is more confident in one’s estimate of one’s own reliability than in one’s estimate of the disputant’s reliability, less (...) doxastic revision is required. I show that Worsnip’s Resilience Account, however intuitive it may be, sometimes issues prescriptions that are clearly irrational. I then argue that Worsnip’s criticisms of “extreme conciliationism” are mistaken. The discussion brings out several important lessons for the epistemology of disagreement: first, while positive net resilience does not affect the degree of conciliation required in one-shot disagreements, over multiple disagreements it may diminish or magnify the required degree of conciliation; second, a common way of framing the disagreement debate is misguided; and third, the focus of the disagreement debate should not be on whether reliability estimates should determine the degree of conciliation, but on what reasons may legitimately ground reliability estimates.

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)

Recent philosophy has paid considerable attention to the way our biases are liable to encroach upon our cognitive lives, diminishing our capacity to know and unjustly denigrating the knowledge of others. The extent of the bias, and the range of domains to which it applies, has struck some as so great as to license talk of a new form of skepticism. I argue that these depressing consequences are real and, in some ways, even more intractable than has previously been recognized. (...) For the difficulties we face in this domain are fueled not only by implicit biases but by various other sorts of entrenched cognitive attitudes we bear toward others, whether or not we judge them to be our peers. Inasmuch as the epistemic standing of this broader set of attitudes is itself quite dubious, the problem of epistemic injustice turns out to be just one special case—albeit of a particularly nasty kind—from a broader domain of cases where the collaborative character of knowledge clashes with tendencies that make collaboration difficult. This makes the threat of skepticism all the greater, and at the same time makes it harder to see what path of escape there might be. (shrink)

In recent work, J. Adam Carter argues that truth-relativism should be compatible with the so-called conformist response to peer disagreement about taste to the effect that subjects should revise their opinions. However, Carter claims that truth-relativism cannot make sense of this response since it cannot make sense of the idea that when two subjects are recognised as epistemic peers, they should acknowledge that they are equally likely to be right about the targeted issue. The main aim of this paper is (...) a modest one: to argue that truth-relativists should not be worried about their alleged incompatibility with conformism for they should be non-conformists.

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)

People may disagree about moral issues because they have fundamentally different intuitions. I argue that we ought to suspend judgement in such cases. Since we trust our own moral intuitions without positive evidence of their reliability, we must necessarily extend this trust to the moral intuitions of others: a fundamental self-other asymmetry in moral epistemology is untenable. This ensures that disagreements in moral intuition are defeating. In addition, I argue that brute conflicts in moral intuition require suspension of judgement only (...) if we are required to exhibit this kind of default trust with respect to the moral intuitions of others.

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)

An introduction to the debate of the epistemic significance of peer disagreement. This article examines the epistemic significance of peer disagreement. It pursues the following questions: (1) How does discovering that an epistemic equal disagrees with you affect your epistemic justification for holding that belief? (e.g., does the evidence of it give you a defeater for you belief?) and (2) Can you rationally maintain your belief in the face of such disagreement? This article explains and motivates each of the central (...) positions, including steadfast views and conciliatory views of peer disagreement, while at the same time raising challenges for each of them. It concludes by speculating about new directions that the debate will take. (shrink)

This paper proposes to reorient the philosophical debate about peer disagreement. The problem of peer disagreement is normally seen as a problem about the extent to which disagreement provides one with evidence against one's own conclusions. It is thus regarded as a problem for individual inquiry. But things look different in more collaborative contexts. Ethical norms relevant to those contexts make a difference to the epistemology. In particular, we argue that a norm of mutual answerability applies to us when we (...) engage in shared inquiry with others, and precludes us from treating one another's conflicting judgments as evidence relevant to the dispute. From this it follows that standard philosophical accounts of peer disagreement—e.g., the Equal Weight View and the Total Evidence View—presuppose that the disagreeing parties are in a sense alienated from one another. It's doubtful that such forms of alienated disagreement should be treated as the central case. (shrink)

In the First Meditation, the Cartesian meditator temporarily concludes that he cannot know anything, because he cannot discriminate dreaming from waking while he is dreaming. To resist the meditator’s conclusion, one could deploy an asymmetry argument. Following Bernard Williams, one could argue that even if the meditator cannot discriminate dreaming from waking while dreaming, it does not follow that he cannot do it while awake. In general, asymmetry arguments seek to identify an asymmetry between a bad case that is entertained (...) as a ground for doubt and a good case in which one takes oneself to know something. My aim in this paper is to consider how effective asymmetry arguments are as an anti-skeptical strategy. I conclude that although asymmetry arguments provide an effective response to dreaming skepticism, they fail as a response to brains-in-a-vat skepticism. (shrink)

When involved in a disagreement, a common reaction is to tell oneself that, given that the information about one’s own epistemic standing is clearly superior in both amount and quality to the information about one’s opponent’s epistemic standing, one is justified in one’s confidence that one’s view is correct. In line with this natural reaction to disagreement, some contributors to the debate on its epistemic significance have claimed that one can stick to one’s guns by relying in part on information (...) about one’s first-order evidence and the functioning of one’s cognitive capacities. In this article, I argue that such a manoeuvre to settle controversies encounters the problem that both disputants can make use of it, the problem that one may be wrong about one’s current conscious experience, and the problem that it is a live possibility that many of one’s beliefs are the product of epistemically distorting factors. I also argue that, even if we grant that personal information is reliable, when it comes to real-life rather than idealized disagreements, the extent of the unpossessed information about one’s opponent’s epistemic standing provides a reason for doubting that personal information can function as a symmetry breaker. (shrink)

It is sometimes claimed that conciliatory views on disagreement ultimately lead to either global or widespread scepticism. This is deemed to be a serious problem for conciliationism either because scepticism of either kind is a patently untenable stance or because it poses a serious threat to our intellectual and social lives. In this paper, I first argue that the alleged untenability of both types of scepticism is far from being obvious and should therefore be established rather than taken for granted, (...) and then that those who reject them because of the threat they pose surprisingly confuse pragmatic reasons with epistemic reasons. (shrink)

An objection that has been raised to the conciliatory stance on the epistemic significance of peer disagreement known as the Equal Weight View is that it is self-defeating, self-undermining, or self-refuting. The proponent of that view claims that equal weight should be given to all the parties to a peer dispute. Hence, if one of his epistemic peers defends the opposite view, he is required to give equal weight to the two rival views, thereby undermining his confidence in the correctness (...) of the Equal Weight View. It seems that the same objection could be leveled against those who claim to suspend judgment in the face of pervasive unresolvable disagreements, as do the Pyrrhonian skeptics. In this paper, I explore the kind of response to the objection that could be offered from a neo-Pyrrhonian perspective, with the aim of better understanding the intriguing character of Pyrrhonian skepticism.

In this paper, I provide a novel explanationist framework for thinking about peer disagreement that solves many of the puzzles regarding disagreement that have troubled epistemologists over the last two decades. Explanationism is the view that a subject is justified in believing a proposition just in case that proposition is part of the best explanation of that subject’s total evidence. Applying explanationism to the problem of peer disagreement yields the following principle: in cases of peer disagreement, the thing that the (...) subjects ought to believe is the thing that is the best explanation of their total evidence, where part of their evidence is the fact that they happen to find themselves in disagreement with an epistemic peer. In what follows, I show how to understand and apply this core idea. (shrink)

This article defends a specific account of reasonableness as a virtue of liberal citizenship. I specify an account of reasonableness that I argue is more consistent with the phenomenology of intersubjective exchanges among citizens over political matters in contexts of deep disagreement. My reading requires reasonable citizens to undertake an attitude of epistemic modesty while deliberating public matters with agents who hold views different from theirs. In contrast with my view, I debate Martha Nussbaum’s and Steven Wall’s accounts of reasonableness (...) and specify why I believe that these proposals, although interesting, both require revisions. Distinguishing my account from theirs, I specify the normative relation between reasonableness and a general framework of political legitimacy that identifies citizens as ‘co-authors of democratic decisions’. Here, I argue that the liberal ideal of ascribing to each member of the constituency the status of putative epistemic authority can be properly fulfilled if coupled with a correct specification of the political ideal of mutual respect. I conclude claiming that opacity respect, a notion of respect according to which the recognition respect that is owed to individuals is expressed by the idea that we have to treat them as ‘opaque’, is the most adequate concept of political respect when dealing with interpersonal deliberations at political level in contexts of deep disagreement.

There is a controversy, within social epistemology, over how to handle disagreement among epistemic peers. Call this the problem of peer disagreement. There is a solution, i.e. the equal-weight view, which says that disagreement among epistemic peers is a reason for each peer to lower the credence they place in their respective positions. However, this solution is susceptible to a serious challenge. Call it the merely modal peers challenge. Throughout parts of modal space, which resemble the actual world almost completely, (...) there are hordes of epistemic peers, who disagree with almost any arbitrarily chosen belief had by residents of the actual world. Further, the mere modality of these peers is not itself an epistemic difference-maker. Thus, on the equal-weight view, we should significantly lower the credence we place in most of our beliefs. Surely, this is seriously mistaken. Thus, there are serious considerations that cut against the equal-weight view. (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)
