Controversy over the epistemology of disagreement endures because there is an unnoticed factor at work: the intrinsic value we give to self-trust. Even if there are many instances of disagreement where, from a strictly epistemic or rational point of view, we ought to suspend belief, there are other values at work that influence our all-things considered judgments about what we ought to believe. Hence those who would give equal-weight to both sides in many cases of disagreement may be right, from (...) the perspective of pure rationality. But their critics are right too, in seeing something undesirable in the consequences of giving equal weight. Among epistemologists, there is a tendency to set aside trust and other such non-epistemic factors, on the grounds that these are not germane to their topic. But ultimately, the value of self-trust shows signs of encroaching on the strictly epistemic question of when our beliefs may be said to be justified. Hence again, even if the equal-weighters are right about what is rational, they may be wrong about what knowledge requires. (shrink)

According to moral intuitionism, at least some moral seeming states are justification-conferring. The primary defense of this view currently comes from advocates of the standard account, who take the justification-conferring power of a moral seeming to be determined by its phenomenological credentials alone. However, the standard account is vulnerable to a problem. In brief, the standard account implies that moral knowledge is seriously undermined by those commonplace moral disagreements in which both agents have equally good phenomenological credentials supporting their disputed (...) moral beliefs. However, it is implausible to think that commonplace disagreement seriously undermines moral knowledge, and thus it is implausible to think that the standard account of moral intuitionism is true.

Should learning we disagree about p lead you to reduce confidence in p? Some who think so want to except beliefs in which you are rationally highly confident. I argue that this is wrong; we should reject accounts that rely on this intuitive thought. I then show that quite the opposite holds: factors that justify low confidence in p also make disagreement about p less significant. I examine two such factors: your antecedent expectations about your peers’ opinions and the difficulty (...) of evaluating your evidence. I close by proposing a different way of thinking about disagreement. (shrink)

What is the rational response to disagreement with an epistemic peer? Some say the steadfast response of holding on to your own belief can be rational; others argue that some degree of conciliation is always rationally required. I argue that only an epistemological externalist about rationality—someone who holds that the rationality of a belief is partly constituted by factors outside a subject’s cognitive perspective—can defend the steadfast view. Or at least that this is so in the kinds of idealized cases (...) of peer disagreement that take center stage in the current debate about disagreement. The argument has three steps. First, I show how rationality internalism motivates conciliationism: in view of the mutually recognized internal epistemic symmetry between peers, it would be arbitrary for either peer to hold on to her own belief. Second, I strengthen this line of thought by considering various proposed ‘symmetry breakers’ that appear to introduce a relevant asymmetry between peers, which could be used to defend the rationality of a steadfast response. I argue that none of these alleged symmetry breakers can help internalists. Third, I show how externalism does have the resources to defend steadfastness and expose how extant defenses of steadfastness implicitly rely on externalist intuitions. (shrink)

I investigate the implication of the truth-relativist’s alleged ‘ faultless disagreements’ for issues in the epistemology of disagreement. A conclusion I draw is that the type of disagreement the truth-relativist claims to preserve fails in principle to be epistemically significant in the way we should expect disagreements to be in social-epistemic practice. In particular, the fact of faultless disagreement fails to ever play the epistemically significant role of making doxastic revision rationally required for either party in a disagreement. That the (...) truth-relativists’ disagreements over centred content fail to play this epistemically significant role that disagreements characteristically play in social epistemology should leave us sceptical that disagreement is what the truth-relativist has actually preserved. (shrink)

In disagreements about trivial matters, it often seems appropriate for disputing parties to adopt a ‘middle ground’ view about the disputed matter. But in disputes about more substantial controversies (e.g. in ethics, religion, or politics) this sort of doxastic conduct can seem viciously acquiescent. How should we distinguish between the two kinds of cases, and thereby account for our divergent intuitions about how we ought to respond to them? One possibility is to say that ceding ground in a trivial dispute (...) is appropriate because the disputing parties are usually epistemic peers within the relevant domain, whereas in a more substantial disagreement the disputing parties rarely, if ever, qualify as epistemic peers, and so ‘sticking to one’s guns’ is usually the appropriate doxastic response. My aim in this paper is to explain why this way of drawing the desired distinction is ultimately problematic, even if it seems promising at first blush. (shrink)

Sometimes we get what seem to be good reasons for believing that we’ve misevaluated our evidence for a proposition P. In those cases, can we use our evidence for P itself to show that we haven’t misevaluated our evidence for P? I show why doing so appears to employ viciously circular reasoning. However, I then argue that this appearance is illusory in certain cases and that we sometimes can legitimately reason in that way. This claim sheds new light on the (...) nature of epistemic undermining and epistemic circularity. In addition, it has implications for the current debate about the epistemic significance of disagreement. An important and influential position in that debate says that disagreement with others dramatically undermines our justification for a wide range of our opinions (e.g., political, religious, moral, economic, and philosophical opinions). My view on undermining and circularity implies that this position on disagreement rests on a mistake. (shrink)

There has been a recent explosion of interest in the epistemology of disagreement. Much of the recent literature is concerned with a particular range of puzzle cases (discussed in the Cases section of my paper). Almost all of the papers that contribute to that recent literature make mention of questions about religious disagreement in ways that suggest that there are interesting connections between those puzzle cases and real life cases of religious disagreement. One important aim of my paper is to (...) cast doubt on that suggestion. More generally, the aim of my paper is to give a reasonably full account of the recent literature on the epistemology of disagreement, and then to give a serious discussion of some of the epistemological issues that are raised by real world religious disagreements.

Dos clases de desacuerdo han resultado de gran interés para la epistemología social durante las últimas décadas: los desacuerdos profundos, que tienen lugar cuando la disputa entre las partes es sistemática y particularmente difícil de resolver, y los desacuerdos entre pares epistémicos, ocasionados por el enfrentamiento entre agentes que tienen la misma evidencia y virtudes cognitivas respecto del tema en discusión. El propósito de este artículo es trabajar en la intersección de ellos, evaluando las consecuencias de que un desacuerdo entre (...) pares sea profundo. En particular, argumento que, cuando un desacuerdo llega a niveles de profundidad muy altos, es imposible que las partes se reconozcan entre sí como pares, dado que no pueden asumir que son igualmente racionales.

This Element engages with the epistemic significance of disagreement, focusing on its skeptical implications. It examines various types of disagreement-motivated skepticism in ancient philosophy, ethics, philosophy of religion, and general epistemology. In each case, it favors suspension of judgment as the seemingly appropriate response to the realization of disagreement. One main line of argument pursued in the Element is that, since in real-life disputes we have limited or inaccurate information about both our own epistemic standing and the epistemic standing of (...) our dissenters, personal information and self-trust can rarely function as symmetry breakers in favor of our own views.

While the epistemic significance of disagreement has been a popular topic in epistemology for at least a decade, little attention has been paid to logical disagreement. This monograph is meant as a remedy. The text starts with an extensive literature review of the epistemology of (peer) disagreement and sets the stage for an epistemological study of logical disagreement. The guiding thread for the rest of the work is then three distinct readings of the ambiguous term ‘logical disagreement’. Chapters 1 and (...) 2 focus on the Ad Hoc Reading according to which logical disagreements occur when two subjects take incompatible doxastic attitudes toward a specific proposition in or about logic. Chapter 2 presents a new counterexample to the widely discussed Uniqueness Thesis. Chapters 3 and 4 focus on the Theory Choice Reading of ‘logical disagreement’. According to this interpretation, logical disagreements occur at the level of entire logical theories rather than individual entailment-claims. Chapter 4 concerns a key question from the philosophy of logic, viz., how we have epistemic justification for claims about logical consequence. In Chapters 5 and 6 we turn to the Akrasia Reading. On this reading, logical disagreements occur when there is a mismatch between the deductive strength of one’s background logic and the logical theory one prefers (officially). Chapter 6 introduces logical akrasia by analogy to epistemic akrasia and presents a novel dilemma. Chapter 7 revisits the epistemology of peer disagreement and argues that the epistemic significance of central principles from the literature are at best deflated in the context of logical disagreement. The chapter also develops a simple formal model of deep disagreement in Default Logic, relating this to our general discussion of logical disagreement. The monograph ends in an epilogue with some reflections on the potential epistemic significance of convergence in logical theorizing. (shrink)

What attitude should philosophers take toward their favorite philosophical theories? I argue that the answer is belief and middling to low credence. I begin by discussing why disagreement has motivated the view that we cannot rationally believe our philosophical theories. Then, I show why considerations from disagreement actually better support my view. I provide two additional arguments for my view: the first concerns roles for belief and credence and the second explains why believing one’s philosophical theories is superior to accepting (...) them. I close by addressing objections, including implications my view has for the Lockean thesis, the view that there is a normative connection between belief and high credence. (shrink)

The problem of disagreement is one of the most important issues that have been debated in epistemology in recent years, and in particular the peer disagreement. The main question of this problem is what kind of attitude we should rationally adopt when we realize that someone who is an epistemic peer to us does not think the same. There are four main responses to this question: conciliationism, steadfastness, total evidence view, and justificationist view. In this article, first I will briefly (...) examine these four views and deal with the points where they fail to satisfy. Later, I will argue that resolution of the disagreement should be case-based. And finally, I will present the evidence-based argument in peer disagreement which is my own response to this problem and explain it with sample cases. (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.

The dominant theory of the evolution of moral cognition across a variety of fields is that moral cognition is a biological adaptation to foster social cooperation. This chapter argues, to the contrary, that moral cognition is likely an evolutionary exaptation: a form of cognition where neurobiological capacities selected for in our evolutionary history for a variety of different reasons—many unrelated to social cooperation—were put to a new, prosocial use after the fact through individual rationality, learning, and the development and transmission (...) of social norms. This chapter begins with a brief overview of the emerging behavioral neuroscience of moral cognition. It then outlines a novel theory of moral cognition that I have previously argued explains these findings better than alternatives. Finally, it shows how the evidence for this theory of moral cognition and human evolutionary history together suggest that moral cognition is likely not a biological adaptation. Instead, like reading sheet music or riding a bicycle, moral cognition is something that individuals learn to do—in this case, in response to sociocultural norms created in our ancestral history and passed down through the ages to enable cooperative living.

Traditionally, an adequate strategy to deal with the tension between liberty and security has been toleration, for the latter allows the maximization of individual liberty without endangering security, since it embraces the limits set by the harm principle and the principle of self-defense of the liberal order. The area outside the boundary clearly requires repressive measures to protect the security and the rights of all. In this paper, we focus on the balance of liberty and security afforded by toleration, analyzing (...) how this strategy works in highly conflictual contexts and sorting out the different sets of reason that might motivate individual to assume a tolerant attitude. We contend that toleration represents a reliable political solution to conflicts potentially threatening social security when it is coupled with social tolerance. Hence, we examine the reasons the agents may have for endorsing toleration despite disagreement and disapproval. In the range of these reasons, we argue that the right reasons are those preserving the moral and epistemic integrity of the agent. The right reasons are however not accessible to everyone, as for example is the case with (non-violent) religious fundamentalists. Only prudential reasons for toleration seem to be available to them. And yet, we argue that an open and inclusive democracy should in principle be hospitable towards prudential and pragmatic reasons as well, which may potentially lay the grounds for future cooperation. We conclude therefore that the tolerant society has room for the fundamentalists, granted that they do not resort to violence. (shrink)

Many of us are unmoved when it is objected that some morally or intellectually suspect source agrees with our belief. While we may tend to find this kind of guilt by epistemic association unproblematic, I argue that this tendency is a mistake. We sometimes face what I call the problem of unwelcome epistemic company. This is the problem of encountering agreement about the content of your belief from a source whose faults give you reason to worry about the belief's truth, (...) normative status, etiology, or implications. On the basis of an array of cases, I elaborate four distinct kinds of problems that unwelcome epistemic company poses. Two of these are distinctly epistemic, and two are moral. I canvass possible responses, ranging from stubbornness to an epistemic prudishness that avoids unwelcome company at all costs. Finally, I offer preliminary lessons of the problem and distinguish it from the problem of peer disagreement. (shrink)

Richard Feldman’s “Reasonable Religious Disagreements” launched debates about the epistemic significance of disagreement that have been a dominant point of discussion in epistemology as of late. While most of these debates have been concerned with disagreement more generally, Feldman’s original focus was religious disagreement, and John Pittard returns the focus to religious disagreement in Disagreement, Deference, and Religious Commitment. Pittard’s book delves deeply into debates about the significance of disagreement with a foot in both epistemology and philosophy of religion. It (...) is the first book to look at these issues as they are being addressed within each of these sub-disciplines and is sure to be a significant contribution to the debates in both sub-fields.

I argue that recognizing a distinct doxastic attitude called endorsement, along with the epistemic norms governing it, solves the self-undermining problem for conciliationism about disagreement. I provide a novel account of how the self-undermining problem works by pointing out the auxiliary assumptions the objection relies on. These assumptions include commitment to certain epistemic principles linking belief in a theory to following prescriptions of that theory. I then argue that we have independent reason to recognize the attitude of endorsement. Endorsement is (...) the attitude of resilient and committed advocacy which is appropriate for researchers to have toward their own theory. Recognizing the importance of endorsement, and of its resiliency, gives us reason to deny the epistemic principles that serve as auxiliary assumptions in the self-undermining objection. This defuses the objection, and provides additional support for the theory of endorsement. (shrink)

The accusation of virtue signalling is typically understood as a serious charge. Those accused usually respond by attempting to show that they are doing no such thing. In this paper, I argue that we ought to embrace the charge, rather than angrily reject it. I argue that this response can draw support from cognitive science, on the one hand, and from social epistemology on the other. I claim that we may appropriately concede that what we are doing is virtue signalling, (...) because virtue signalling is morally appropriate. It neither expresses vices, nor is hypocritical, nor does it degrade the quality of public moral discourse. Signalling our commitment to norms is a central and justifiable function of moral discourse, and the same signals provide evidence that is appropriately taken into account in forming moral beliefs.

Disagreement and debunking arguments threaten religious belief. In this paper, I draw attention to two types of propositions and show how they reveal new ways to respond to debunking arguments and disagreement. The first type of proposition is the epistemically self-promoting proposition, which, when justifiedly believed, gives one a reason to think that one reliably believes it. Such a proposition plays a key role in my argument that some religious believers can permissibly wield an epistemically circular argument in response to (...) certain debunking arguments. The second type of proposition is the epistemically others-demoting proposition, which, when justifiedly believed, gives one a reason to think that others are unreliable with respect to it. Such a proposition plays a key role in my argument that some religious believers can permissibly wield a question-begging argument to respond to certain types of disagreement. (shrink)

This book presents an original discussion and analysis of epistemic peer disagreement. It reviews a wide range of cases from the literature, and extends the definition of epistemic peerhood with respect to the current one, to account for the actual variability found in real-world examples. The book offers a number of arguments supporting the variability in the nature and in the range of disagreements, and outlines the main benefits of disagreement among peers i.e. what the author calls the benefits to (...) inquiry argument.

This paper sketches a general account of how to respond in an epistemically rational way to moral disagreement. Roughly, the account states that when two parties, A and B, disagree as to whether p, A says p while B says not-p, this is higher-order evidence that A has made a cognitive error on the first-order level of reasoning in coming to believe that p (and likewise for B with respect to not-p). If such higher-order evidence is not defeated, then one (...) rationally ought to reduce one’s confidence with respect to the proposition in question. We term this the higher-order evidence account (the HOE account), and present it as a superior to what we might call standard conciliationism, which holds that when agents A and B disagree about p, and are (known) epistemic peers, they should both suspend judgement about p or adjust their confidence towards the mean of A and B’s prior credences in p. Many have suspected that standard conciliationism is implausible and may have skeptical implications. After presenting the HOE account, we put it to work by applying it to a range of cases of moral disagreement, including those that have feature in recent debates assuming standard conciliationism. We show that the HOE account support reasonable, non-skeptical verdicts in a range of cases. Note that this is a paper on moral disagreement, not on the HOE account, thus the account is merely stated here, while defended more fully elsewhere. (shrink)

For over a decade now epistemologists have been thinking about the peer disagreement problem of whether a person is reasonable in not lowering her confidence in her belief P when she comes to accept that she has an epistemic peer on P who disbelieves P. However, epistemologists have overlooked a key realistic way how epistemic peers can, or even have to, differ epistemically—a way that reveals the inadequacy of both conformist and non-conformist views on peer disagreement by uncovering how the (...) causes of peer disagreement bear on the debate’s core philosophical issue. Part of our argument for this thesis will involve giving a thorough yet entirely informal presentation of mathematical theorems in economics by Robert Aumann :1236–1239,1976) and Polemarchakis and Geneakoplos which represent a formally precise description of how two rational agents must deal with disagreement under certain epistemically interesting circumstances.

Disagreement is a ubiquitous feature of human life, and philosophers have dutifully attended to it. One important question related to disagreement is epistemological: How does a rational person change her beliefs (if at all) in light of disagreement from others? The typical methodology for answering this question is to endorse a steadfast or conciliatory disagreement norm (and not both) on a priori grounds and selected intuitive cases. In this paper, I argue that this methodology is misguided. Instead, a thoroughgoingly Bayesian (...) strategy is what's needed. Such a strategy provides conciliatory norms in appropriate cases and steadfast norms in appropriate cases. I argue, further, that the few extant efforts to address disagreement in the Bayesian spirit are laudable but uncompelling. A modelling, rather than a functional, approach gets us the right norms and is highly general, allowing the epistemologist to deal with (1) multiple epistemic interlocutors, (2) epistemic superiors and inferiors (i.e. not just epistemic peers), and (3) dependence between interlocutors. (shrink)

Religious disagreements are widespread. Some philosophers have argued that religious disagreements call for religious skepticism, or a revision of one’s religious beliefs. In order to figure out the epistemic significance of religious disagreements, two questions need to be answered. First, what kind of disagreements are religious disagreements? Second, how should one respond to such disagreements? In this paper, I argue that many religious disagreements are cases of unconfirmed superiority disagreements, where parties have good reason to think they are not epistemic (...) peers, yet they lack good reason to determine who is superior. Such disagreements have been left relatively unexplored. I then argue that in cases of unconfirmed superiority disagreements, disputants can remain relatively steadfast in holding to their beliefs. Hence, we can remain relatively steadfast in our beliefs in such cases of religious disagreements. (shrink)

A familiar complaint about conciliatory approaches to disagreement is that they are self-defeating or incoherent because they ‘call for their own rejection’. This complaint seems to be influential but it isn’t clear whether conciliatory views call for their own rejection or what, if anything, this tells us about the coherence of such views. We shall look at two ways of developing this self-defeat objection and we shall see that conciliatory views emerge unscathed. A simple version of the self-defeat objection leaves (...) conciliatory views untouched. A subtle version of the objection contains a subtle but overlooked flaw. If the conciliatory view is right, it might be right to be dogmatically conciliatory (i.e., to continue to be conciliatory however objectionable this might seem to ourselves and to others). (shrink)

The scientific community, we hold, often provides society with knowledge—that the HIV virus causes AIDS, that anthropogenic climate change is underway, that the MMR vaccine is safe. Some deny that we have this knowledge, however, and work to undermine it in others. It has been common to refer to such agents as “denialists”. At first glance, then, denialism appears to be a form of skepticism. But while we know that various denialist strategies for suppressing belief are generally effective, little is (...) known about which strategies are most effective. We see this as an important first step toward their remediation. This paper leverages the approximate comparison to various forms of philosophical skepticism to design an experimental test of the efficacy of four broad strategies of denial at suppressing belief in specific scientific claims. Our results suggest that assertive strategies are more effective at suppressing belief than questioning strategies. (shrink)

According to an influential Enlightenment ideal, one shouldn't rely epistemically on other people's say-so, at least not if one is in a position to evaluate the relevant evidence for oneself. However, in much recent work in social epistemology, we are urged to dispense with this ideal, which is seen as stemming from a misguided focus on isolated individuals to the exclusion of groups and communities. In this paper, I argue that that an emphasis on the social nature of inquiry should (...) not lead us to entirely abandon the Enlightenment ideal of epistemically autonomous agents. Specifically, I suggest that it is an appropriate ideal for those who serve as experts in a given epistemic community, and develop a notion of expert acceptance to make sense of this. I go on to show that, all other things being equal, this kind of epistemic autonomy among experts makes their joint testimony more reliable, which in turn brings epistemic benefits both to laypeople and to experts in other fields.

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)

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.

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)

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)

Many writers have recently argued that there is something distinctively problematic about sustaining moral beliefs on the basis of others’ moral views. Call this claim pessimism about moral deference. Pessimism about moral deference, if true, seems to provide an attractive way to argue for a bold conclusion about moral disagreement: moral disagreement generally does not require belief revision. Call this claim steadfastness about moral disagreement. Perhaps the most prominent recent discussion of the connection between moral deference and moral disagreement, due (...) to Alison Hills, uses pessimism about the former to argue for steadfastness about the latter. This paper reveals that this line of thinking, and others like it, are unsuccessful. There is no way to argue from a compelling version of pessimism about moral deference to the conclusion of steadfastness about moral disagreement. The most plausible versions of pessimism about moral deference have only very limited implications for moral disagreement. (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?

This paper is about how moral disagreement matters for metaethics. It has four parts. In the first part I argue that moral facts are subject to a certain epistemic accessibility requirement. Namely, moral facts must be accessible to some possible agent. In the second part I show that because this accessibility requirement on moral facts holds, there is a route from facts about the moral disagreements of agents in idealized conditions to conclusions about what moral facts there are. In the (...) third part I build on this route to show that (*) if there is significant moral disagreement in idealized conditions, then our understanding of morality is fatally flawed and we should accept relativism over non-naturalism and quasi-realism. So, if, like many, you think that there would be significant moral disagreement in idealized conditions, you should hold that our understanding of morality is fatally flawed and reject non-naturalism and quasi-realism. In the fourth part of this paper I show that (*) undermines the plausibility of non-naturalism, quasi-realism, and the view that our understanding of morality is not fatally flawed even if we do not have sufficient reason to believe that there would be significant moral disagreement in idealized conditions.

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)

We introduce a family of rules for adjusting one's credences in response to learning the credences of others. These rules have a number of desirable features. 1. They yield the posterior credences that would result from updating by standard Bayesian conditionalization on one's peers' reported credences if one's likelihood function takes a particular simple form. 2. In the simplest form, they are symmetric among the agents in the group. 3. They map neatly onto the familiar Condorcet voting results. 4. They (...) preserve shared agreement about independence in a wide range of cases. 5. They commute with conditionalization and with multiple peer updates. Importantly, these rules have a surprising property that we call synergy - peer testimony of credences can provide mutually supporting evidence raising an individual's credence higher than any peer's initial prior report. At first, this may seem to be a strike against them. We argue, however, that synergy is actually a desirable feature and the failure of other updating rules to yield synergy is a strike against them.

The Equal Weight View holds that, when we discover we disagree with an epistemic peer, we should give our peer’s judgment as much weight as our own. But how should we respond when we cannot tell whether those who disagree with us are our epistemic peers? I argue for a position I will call the Earn-a-Spine View. According to this view, parties to a disagreement can remain confident, at least in some situations, by finding justifiable reasons to think their opponents (...) are less credible than themselves, even if those reasons are justifiable only because they lack information about their opponents.

The argument from faultless disagreement employed by the relativist purports to show that contextualism falls short of explaining cases of faultless disagreement. The demonstration is intended to give credence to the relativist semantics of epistemic modality expressions. In this paper we present some cases showing that even though cases of faultless disagreement do reveal some intrinsic features of epistemic modality claims, they do not support the relativist semantics. The sophistication of faultless disagreement goes beyond what the relativist semantics can cope (...) with. We also advance an epistemologically oriented proposal to account for faultless disagreement. (shrink)

This paper proposes a methodological turn for the epistemology of disagreement, away from focusing on highly idealized cases of peer disagreement and towards an increased focus on disagreement simpliciter. We propose and develop a normative framework for evaluating all cases of disagreement as to whether something is the case independently of their composition—i.e., independently of whether they are between peers or not. The upshot will be a norm of disagreement on which what one should do when faced with a disagreeing (...) party is to improve the epistemic properties of one’s doxastic attitude or, alternatively, hold steadfast.

In this paper, I discuss some of the recent developments in the political turn of Social Epistemology, focusing on the notions of epistemic injustice and epistemic oppression. In the first part of the work, I introduce Kristie Dotson’s characterization of the epistemic injustices presented by Miranda Fricker, through the understanding of systematic ways of violating epistemic agency in terms of oppressions. In the second part, I discuss Dotson’s critique of Fricker on the grounds that there is an important kind of (...) epistemic injustice that is not dealt with in Fricker’s proposal, and which could help us to perceive a particular, pervasive kind of violation of the epistemic agency.

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.
