Belnap-Dunn logic, sometimes also known as First Degree Entailment, is a four-valued propositional logic that complements the classical truth values of True and False with two non-classical truth values Neither and Both. The latter two are to account for the possibility of the available information being incomplete or providing contradictory evidence. In this paper, we present a probabilistic extension of BD that permits agents to have probabilistic beliefs about the truth and falsity of a proposition. We provide a sound and (...) complete axiomatization for the framework defined and also identify policies for conditionalization and aggregation. Concretely, we introduce four-valued equivalents of Bayes’ and Jeffrey updating and also suggest mechanisms for aggregating information from different sources. (shrink)

It is widely accepted that one strong motivation for adopting a conciliatory stance with regard to the epistemology of peer disagreement is that the non-conciliatory alternatives are incompatible with the demands of intellectual character, and incompatible with the virtue of intellectual humility in particular. It is argued that this is a mistake, at least once we properly understand what intellectual humility involves. Given some of the inherent problems facing conciliatory proposals, it is maintained that non-conciliatory approaches to epistemic peer disagreement (...) are thus on much stronger dialectical ground than many suppose, including some defenders of this line. In particular, non-conciliatory proposals can resist the idea that epistemic peer disagreement directly weakens one’s epistemic justification, as conciliatory views maintain. This means that the epistemic justification that our beliefs in this regard enjoy, and thus our knowledge, is more secure than conciliatory approaches to epistemic peer disagreement would suggest.

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)

This chapter brings together debates in political philosophy and epistemology over what we should do when we disagree. While it might be tempting to think that we can apply one debate to the other, there are significant differences that may threaten this project. The specification of who qualifies as a civic or epistemic peer are not coextensive, utilizing different idealizations in denoting peerhood. In addition, the scope of disagreements that are relevant vary according to whether the methodology chosen falls within (...) ideal theory or nonideal theory. Finally, the two literatures focus on different units of analysis that diverge according to the philosophical purpose behind their investigation of disagreement. Epistemologists analyze the rationality of individuals’ belief states whereas political philosophers focus on the just governance of a diverse society. Despite these differences, political epistemologists can learn valuable lessons by considering these debates side by side in order to provide insights that address a host of different challenges posed by political disagreement. The core lesson to draw from the disanalogies outlined in this paper is that to make progress, careful attention should be paid to specifying the goal of any particular project within political epistemology.

Conciliationism—the thesis that when epistemic peers discover that they disagree about a proposition, both should reduce their confidence—faces a major objection: it seems to require us to significantly reduce our confidence in our central moral and political commitments. In this paper, I develop a typology of disagreement cases and a diagnosis of the source and force of the pressure to conciliate. Building on Vavova’s work, I argue that ordinary and extreme disagreements are surprising, and for this reason, they carry information (...) about the likelihood of error. But deep disagreement is not surprising at all, and token deep disagreements do not put pressure on us to conciliate. However, a pattern of deep disagreements points to a different concern: not the problem of disagreement but the problem of irrelevant influences. Deep disagreement constitutes some pressure to examine the foundations from which we reason, rather than to conciliate on our central moral and political claims. (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.

No-platforming—the refusal to allow those who espouse views seen as inflammatory the opportunity to speak in certain forums—is very controversial. Proponents typically cite the possibility of harms to disadvantaged groups and, sometimes, epistemically paternalistic considerations. Opponents invoke the value of free speech and respect for intellectual autonomy in favor of more open speech, arguing that the harms that might arise from bad speech are best addressed by rebuttal, not silencing. In this article, I argue that there is a powerful consideration (...) in favor of no-platforming some speakers: allowing them a platform generates genuine higher-order evidence in favor of their claims. When that higher-order evidence would be misleading, we may reasonably believe it should not be generated. (shrink)

Epistemic permissivism is the view that it is possible for two people to rationally hold incompatible attitudes toward some proposition on the basis of one body of evidence. In this paper, I defend a particular version of permissivism – unacknowledged permissivism (UP) – which says that permissivism is true, but that no one can ever rationally believe that she is in a permissive case. I show that counter to what virtually all authors who have discussed UP claim, UP is an (...) attractive view: it is compatible with the intuitive motivations for permissivism and avoids a significant challenge to permissivism: the arbitrariness objection. (shrink)

Conciliationism is the view that an agent must revise her belief in a proposition when she becomes aware that there is an epistemic peer who disagrees with her about that proposition. If epistemic peers are anything less than strict cognitive and evidential equals, then even slight differences could explain away why the two parties disagree in the first place. But this strict notion of peerhood never obtains in many, if not most, of real-life cases disagreements between inquirers. One recent account (...) of peerhood which might obtain more frequently in cases of real-life disagreements comes from Elgin Voicing dissent: the ethics and epistemology of making disagreement public, Routledge, New York, pp 10–21, 2018). She argues that two scientists who are epistemic peers can disagree because while they might have the same reasoning abilities, they can have different reasoning styles. While there are merits to Elgin’s account, I argue that two people with different reasoning styles are unlikely to be epistemic peers since such differences could serve to explain away why they disagree. I argue that there is a conception of peerhood which can retain the sceptical force of conciliationism without trivializing or dismissing the problem of disagreement. I then conclude that a particularly attractive argument against conciliationism is gestured at by Elgin in one of her earlier pieces on disagreement. This argument is based on the idea that there are epistemic benefits to be gained from remaining steadfast in the face of disagreement Disagreement, Oxford University Press, Oxford, pp 53–68, 2010). The success of this argument, however, might force an inquirer faced with disagreement to choose between synchronic reasons and diachronic reasons. If Hughes’ recent defense of epistemic dilemmism is correct this may be a feature of the argument, rather than a bug. (shrink)

Two kinds of considerations are thought to be relevant to the correct response to the discovery of a peer who disagrees with you about some question. The first is general principles pertaining to disagreement. According to the second kind of consideration, a theory about the correct response to peer disagreement must conform to our intuitions about test cases. In this paper, I argue against the assumption that imperfect conformity to our intuitions about test cases must count against a theory about (...) peer disagreement, offer a principled way of shrugging off a theory’s failure to deliver the intuitive verdict, and consider the main extant theories from the new methodological perspective.

Moral disagreement is sometimes thought to pose problems for moral realism because it shows that we cannot achieve knowledge of the moral facts the realists posit. In particular, it is "fundamental" moral disagreement—that is, disagreement that is not due to distorting factors such as ignorance of relevant nonmoral facts, bad reasoning skills, or the like—that is supposed to generate skeptical implications. In this paper, we show that this version of the disagreement challenge is flawed as it stands. The reason is (...) that the epistemic assumptions it requires are incompatible with the possibility of fundamental disagreement. However, we also present an alternative reconstruction of the challenge that avoids the problem. The challenge we present crucially invokes the principle that knowledge requires "adherence". While that requirement is usually not discussed in this context, we argue that it provides a promising explanation of why disagreement sometimes leads to skepticism. (shrink)

This thesis defends John Rawls’s constructivist theory of justice against three distinct challenges. -/- Part one addresses G. A. Cohen’s claim that Rawls’s constructivism is committed to a mistaken thesis about the relationship between facts and principles. It argues that Rawls’s constructivist procedure embodies substantial moral commitments, and offers an intra-normative reduction rather than a metaethical account. Rawls’s claims about the role of facts in moral theorizing in A Theory of Justice should be interpreted as suggesting that some of our (...) moral beliefs, which we are inclined to hold without reference to facts, are, in fact, true, because certain facts obtain. This thesis and the acknowledgement of the moral assumptions of Rawls’s constructivism help to show that Rawls does not, and does not need to, deny Cohen’s thesis. -/- Part two defends the characterization of the decision problem in Rawls’s original position as a decision problem under uncertainty. Rawls stipulates that the denizens of the original position lack information that they could use to arrive at estimates of the likelihood of ending up in any given social position. It has been argued that Rawls does not have good grounds for this stipulation. I argue that given the nature of the value function we should attribute to the denizens of the original position and our cognitive limitations, which also apply to the denizens of the original position, their decision problem can be characterized as one under uncertainty even if we stipulate that they know that they have an equal chance of being in any individual’s place. -/- Part three assesses the claim that a true commitment to Rawls’s difference principle requires a further commitment to an egalitarian ethos. This egalitarian ethos is offered as a means to bring about equality and Pareto-optimality. Accordingly, I try to undermine the case for an egalitarian ethos by challenging the desirability of the ends it is supposed to further or by showing that it is redundant. I argue that if primary goods are the metric of justice, then Pareto optimality in the space of the metric of justice is undesirable. I then argue that if the metric of justice is welfare, depending on the theory of welfare we adopt, an egalitarian ethos will either be redundant or will have objectionably paternalistic consequences.

It’s widely accepted that higher-order defeaters, i.e., evidence that one’s belief is formed in an epistemically defective way, can defeat doxastic justification. However, it’s yet unclear how exactly such kind of defeat happens. Given that many theories of doxastic justification can be understood as fitting the schema of proper basing on propositional justifiers, we might attempt to explain the defeat either by arguing that a higher-order defeater defeats propositional justification or by arguing that it defeats proper basing. It has been (...) argued that the first attempt is unpromising because a variety of prominent theories of propositional justification don’t imply that we lose propositional justification when gaining higher-order defeaters. This leads some scholars to take the second attempt. In this paper, I criticize this second attempt, and I defend the first attempt by arguing that a theory of propositional justification that requires intellectual responsibility can nicely account for higher-order defeat. My proposal is that we lose doxastic justification when we gain higher-order defeaters because there is no intellectually responsible way for us to maintain our original beliefs due to the defeaters.

Abstract: Recent years have witnessed a revival of interest in relativism. Proponents have defended various accounts that seek to model the truth-conditions of certain propositions along the lines of standard possible world semantics. The central challenge for such views has been to explain what advantage they have over contextualist theories with regard to the possibility of disagreement. I will press this worry against Max Kölbel’s account of faultless disagreement. My case will proceed along two distinct but connected lines. First, I (...) will argue that the sense of faultlessness made possible by his relativism conflicts with our intuitive understanding of disagreement. And second, that his meta-epistemological commitments are at odds with the socio-epistemic function of disagreement. This latter problem for relativistic accounts of truth has thus far been largely ignored in the literature. (shrink)

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)

A moderate belief-disagreement between agents on proposition p means that one agent believes p and the other agent does not. This paper presents two logical systems, \ and \, that describe moderate belief-disagreement, and shows, using possible worlds semantics, that \ is sound and complete with respect to arbitrary frames, and \ is sound and complete with respect to serial frames. Syntactically, the logics are monomodal, but two doxastic accessibility relations are involved in their semantics. The notion of moderate belief-disagreement, (...) which is in accordance with the understanding of belief-disagreement in everyday life, is an epistemic one related to multiagent situations, and \ and \ are two epistemic logics.

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)

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.

Religious disagreement is, quite understandably, viewed as a problem for religious belief. In this paper, I consider why religious disagreement is a problem—why it is a potential defeater for religious belief—and I propose a way of dealing with this sort of potential defeater. I begin by focusing elsewhere—on arguments for radical skepticism. In section 1, I consider skeptical arguments proposed as potential defeaters for all of our perceptual and memory beliefs and explain what I think the rational response is to (...) such potential defeaters, emphasizing the way epistemic intuitions are involved in both the skeptical arguments and my recommended response. In section 2, I discuss the way in which peer disagreement—on any topic—is a potential defeater for our beliefs, highlighting the conditions under which recognized disagreement is a successful defeater and those under which it isn't. In the third section, I consider how to use a section-1 type of response to deal with a section-2 type of defeater for religious belief. (shrink)

A commonly neglected feature of the so-called Equal Weight View, according to which we should give our peers’ opinions the same weight we give our own, is its prima facie incompatibility with the common picture of philosophy as an armchair activity: an intellectual effort to seek a priori knowledge. This view seems to imply that our beliefs are more likely to be true if we leave our armchair in order to find out whether there actually are peers who, by disagreeing (...) with us, force us to revise our beliefs. This article argues that the Equal Weight View should be spelled out in such a way that not only actual peer disagreement requires us to revise our beliefs, but also merely possible peer disagreement. This result is not a reductio ad absurdum of the view. Quite the opposite: it shows that the view is, contrary to appearance, compatible with our common way of doing philosophy. (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.

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)

Deference to experts is normal in many areas of inquiry, but suspicious in morality. This is puzzling if one thinks that morality is relevantly like those other areas of inquiry. We argue that this suspiciousness can be explained in terms of the suspiciousness of deferring to an epistemic peer. We then argue that this explanation is preferable to others in the literature, and explore some metaethical implications of this result.

To understand rational response to ethical disagreement, we need to consider how epistemic and ethical factors interact. The notion of an ethical peer is developed, and the roles that epistemic and ethical peers play in disagreement are compared. In the light of some literary examples, the view that conciliation in response to an ethical peer can be called for, even if that peer is an epistemic inferior, is defended.

Conciliatory views of disagreement are an intuitive class of views on the epistemic significance of disagreement. Such views claim that making conciliation is often required upon discovering that another disagrees with you. One of the chief objections to these views of the epistemic significance of disagreement is that they are self-defeating. Since, there are disagreements about the epistemic significance of disagreement, such views can be turned on themselves, and this has been thought to be problematic. In this paper, I examine (...) several different incarnations of this objection and defend conciliatory views of disagreement from each of them, while making a modification regarding how such views should be understood.

I treat you as a thermometer when I use your belief states as more or less reliable indicators of the facts. Should I treat myself in a parallel way? Should I think of the outputs of my faculties and yours as like the readings of two thermometers the way a third party would? I explore some of the difficulties in answering these questions. If I am to treat myself as well as others as thermometers in this way, it would appear (...) that I cannot reasonably trust my own convictions over yours unless I have antecedent reason to suppose that I am more likely than you to get things right. I appeal to some probabilistic considerations to suggest that our predicament as thermometers might not actually be as bad as it seems. (shrink)

Earlenbaugh and Molyneux’s argument against considering intuitions as evidence has an uncharitable consequence — a substantial part of philosophical practice is not justified. A possible solution to this problem is to defend that philosophy must be descriptive metaphysics. But if this statement is rejected, one can only argue (a) that experts’ intuition does constitute evidence, and (b) that philosophical practice is justified by the overall growth of philosophical knowledge it generates.

This special issue of Erkenntnis is devoted to the varieties of disagreement that arise in different areas of discourse, and the consequences we should draw from these disagreements, either concerning the subject matter and its objectivity, or concerning our own views about this subject matter if we learn, for example, that an epistemic peer disagrees with our view. In this introduction we sketch the background to the recent philosophical discussions of these questions, and the location occupied therein by the articles (...) in this collection. (shrink)

Much recent discussion in social epistemology has focussed on the question of whether peers can rationally sustain a disagreement. A growing number of social epistemologists hold that the answer is negative. We point to considerations from the history of science that favor rather the opposite answer. However, we also explain how the other position can appear intuitively attractive.

This paper is not concerned with the (amply discussed) question as to the rational response to peer disagreement. Instead, it addresses a (considerably less often debated) problem to which many views about the (epistemic) significance of disagreement are vulnerable (to some extent or another): self-undermining. I reject several answers that have been proposed in the literature, defend one that has been offered (by meeting objections to it), and show that in its light, the prevalent assumption that the ‘equal-weight view’, a (...) prominent view about disagreement, rationally requires us to suspend judgement about contentious matters, is seen to be too pessimistic.

ABSTRACT In this paper, I defend a new solution to the problem of peer disagreement, the question as to how you should respond when you learn that your ‘epistemic peer’ disagrees with you about some issue. I consider four test cases that together impugn every extant full-blown theory about peer disagreement. I present my own solution, show that it delivers the intuitive verdict in the test cases and address some objections.

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 evidence that we get from peer disagreement is especially problematic from a Bayesian point of view since the belief revision caused by a piece of such evidence cannot be modelled along the lines of Bayesian conditionalisation. This paper explains how exactly this problem arises, what features of peer disagreements are responsible for it, and what lessons should be drawn for both the analysis of peer disagreements and Bayesian conditionalisation as a model of evidence acquisition. In particular, it is pointed (...) out that the same characteristic of evidence from disagreement that explains the problems with Bayesian conditionalisation also suggests an interpretation of suspension of belief in terms of imprecise probabilities.

What is the nature of rational disagreement? A number of philosophers have recently addressed this question by examining how we should respond to epistemic conflict with a so-called epistemic peer—that is, someone over whom you enjoy no epistemic advantage. Some say that you're rationally required to suspend judgment in these cases—thereby denying the very possibility of a certain kind of rational disagreement. Others say that it's permissible to retain your beliefs even in the face of epistemic conflict. By distinguishing between (...) close peers and distant peers, I argue that it's rational to respond to different types of peers in different ways. I also argue that remote peers—a particularly distant kind of distant peer—provide us with an important lesson in epistemic humility. (shrink)

If a colleague of mine, whose opinion I respect, disagrees with me about some claim, this might give me pause regarding my position on the matter. The Equal Weight view proposes that in such cases of peer disagreement I ought to give my colleague’s opinion as much weight as my own, and decrease my certainty in the disputed claim. One prominent criticism of the Equal Weight view is that treating higher-order (indirect) evidence in this way invariably swamps first-order (direct) evidence. (...) While the opinions of our peers matter in our deliberations, the Equal Weight view counter-intuitively requires that evidence of mere disagreement is more important than standard kinds of evidence. I offer a proposal for how we should idealize epistemic agents that identifies the variable feature of disagreements that accounts for the shifting significance of direct and indirect evidence in different disagreement contexts. Specifically, by idealizing epistemic agents as deriving functions that characterize the non-subjective relationship between a body of evidence and the reasonableness of believing the various propositions supported by that evidence, we can accommodate the intuition to compromise that motivates the Equal Weight view, without accepting the counter-intuitive results.

Religious disagreement describes the fact that religious and secular beliefs exhibit massive variety, and cannot all be perfectly accurate. It yields a problem and an opportunity. The problem is that, especially given the apparent epistemic parity of many who hold other beliefs, you cannot suppose that your beliefs are accurate. This arguably puts pressure on you to weaken or abandon your beliefs. Responses include denying the parity of those who disa- gree, or denying that religious disagreement speaks strongly against your (...) beliefs. I criticize these, defending an alternative epistemology to those employed by both the problem and the responses. My epistemological view finds a middle-ground between them, and positions us to benefit from the opportunity that religious disagreement offers to improve our beliefs. I ad- dress the objections that the opportunity mentality is unnecessary if God supports our beliefs, that it risks our (true) beliefs, and that it is disloyal to God. (shrink)

The paper presents and defends a Bayesian theory of trust in social networks. In the first part of the paper, we provide justifications for the basic assumptions behind the model, and we give reasons for thinking that the model has plausible consequences for certain kinds of communication. In the second part of the paper we investigate the phenomenon of overconfidence. Many psychological studies have found that people think they are more reliable than they actually are. Using a simulation environment that (...) has been developed in order to make our model computationally tractable we show that in our model inquirers are indeed sometimes better off from an epistemic perspective overestimating the reliability of their own inquiries. We also show, by contrast, that people are rarely better off overestimating the reliability of others. On the basis of these observations we formulate a novel hypothesis about the value of overconfidence. (shrink)

Philosophical responses to religious diversity range from outright rejection of divine reality to claims of religious pluralism. In this paper, I challenge those responses that take the problem of religious diversity to be merely an instance of the general problem of disagreement. To do so, I will take, as my starting point, William Alston’s treatment of the problems that religious diversity seems to pose for the rationality of theistic beliefs. My main aim is to highlight the cognitive penetrability of religious (...) experience as a major source of such problems. I conclude by examining the consequences of cognitive penetration for the reliability of the monotheistic doxastic practice. (shrink)

Can disagreement with my past self about aesthetic matters give a reason to reconsider my present aesthetic verdict and if it does, under what conditions? In other words, can such a disagreement be a sign of my failing in my present aesthetic judgement? In this paper, I argue that revising one’s judgement in response to disagreeing with one’s former self is appropriate but only when the former and the present self share the same aesthetic personality. The possibility of failure in (...) one’s aesthetic judgement is therefore bound up, among other things, with facts about one’s aesthetic identity over time. The resulting view has implications for our understanding of the scope of the autonomy in aesthetics and is consistent with empirical evidence regarding the way in which people evaluate aesthetic judgments.

This paper considers a special case of belief updating—when an agent learns testimonial data, or in other words, the beliefs of others on some issue. The interest in this case is twofold: (1) the linear averaging method for updating on testimony is somewhat popular in epistemology circles, and it is important to assess its normative acceptability, and (2) this facilitates a more general investigation of what it means/requires for an updating method to have a suitable Bayesian representation (taken here as (...) the normative standard). The paper initially defends linear averaging against Bayesian-compatibility concerns raised by Bradley (Soc Choice Welf 29:609-632, 2007), as well as problems associated with multiple testimony updates. The resolution of these issues, however, requires an extremely nuanced interpretation of the parameters of the linear averaging model—the so-called weights of respect. We go on to propose a role that the parameters of any 'shortcut' updating function should play, by way of minimal interpretation of these parameters. The class of updating functions that is consistent with this role, however, excludes linear averaging, at least in its standard form. (shrink)

Conciliatory views of disagreement say, roughly, that it’s rational for you to become less confident in your take on an issue in case you find out that an epistemic peer’s take on it is the opposite. Their intuitive appeal notwithstanding, there are well-known worries about the behavior of conciliatory views in scenarios involving higher-order disagreements, which include disagreements over these views themselves and disagreements over the peer status of alleged epistemic peers. This paper does two things. First, it explains how (...) the core idea behind conciliatory views can be expressed in a defeasible logic framework. The result is a formal model that’s particularly useful for thinking about the behavior of conciliatory views in cases involving higher-order disagreements. And second, the paper uses this model to resolve three paradoxes associated with disagreements over epistemic peerhood. (shrink)

A new strategy in philosophy of law appeals to explanatory gap arguments to attack legal positivism. We argue that the strategy faces a dilemma, which derives from there being two available readings of the constraint it places on legal grounding. To this end, we elaborate the most promising ways of spelling out the epistemic constraints governing law-determination, and show that each of the arguments based on them has problems. Throughout the paper, we evaluate a number of explanatory requirements, ultimately with (...) a view to shedding light on the explanatory nature of both grounding in general, and legal grounding in particular.
