The relativist's central objection to contextualism is that it fails to account for the disagreement we perceive in discourse about "subjective" matters, such as whether stewed prunes are delicious. If we are to adjudicate between contextualism and relativism, then, we must first get clear about what it is for two people to disagree. This question turns out to be surprisingly difficult to answer. A partial answer is given here; although it is incomplete, it does help shape what the relativist (...) must say if she is to do better than the contextualist in securing genuine disagreement.

This paper explores some alternative accounts of doxastic disagreement, and shows what problems each faces. It offers an account of doxastic disagreement that results from the incompatibility of the content of doxastic attitudes, even when that content’s truth is relativized. On the best definition possible, it is argued, neither non-indexical contextualism nor assessment-relativism have an advantage over contextualism. The conclusion is that conflicts that arise from the incompatibility (at the same world) of the content of given doxastic attitudes (...) cannot be accommodated by theoretical positions that allow for the compatibility (at the same world) of the content of different doxastic attitudes.

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.

In this paper we argue that there is a kind of moral disagreement that survives the Rawlsian veil of ignorance. While a veil of ignorance eliminates sources of disagreement stemming from self-interest, it does not do anything to eliminate deeper sources of disagreement. These disagreements not only persist, but transform their structure once behind the veil of ignorance. We consider formal frameworks for exploring these differences in structure between interested and disinterested disagreement, and argue that consensus (...) models offer us a solution concept for disagreements behind the veil of ignorance.

The equal weight view says that if you discover that you disagree with a peer, you should decrease your confidence that you are in the right. Since peer disagreement seems to be quite prevalent, the equal weight view seems to tell us that we cannot reasonably believe many of the interesting things we believe because we can always count on a peer to contest the interesting things that we believe. While the equal weight view seems to have skeptical implications, (...) few epistemologists worry about these implications because the equal weight view is quickly falling out of favor. In this paper, I present an analogical argument for the view and defend it from critics who think that we can justifiably retain confidence in the face of peer disagreement. (shrink)

In constructing semantic theories of normative and evaluative terms, philosophers have commonly deployed a certain type of disagreement -based argument. The premise of the argument observes the possibility of genuine disagreement between users of a certain normative or evaluative term, while the conclusion of the argument is that, however differently those speakers employ the term, they must mean the same thing by it. After all, if they did not, then they would not really disagree. We argue that in (...) many of the cases in which this argument is deployed, the conclusion not only fails to follow from the premises, but is very likely false. Disagreements between speakers who do not mean the same things by their words are common, genuine, and not easily distinguished from ordinary disagreements over the truth of literally expressed content. We make this case by developing the notion of a metalinguistic negotiation, an exchange in which speakers tacitly negotiate the proper deployment of some linguistic expression in a context. Metalinguistic negotiations express disagreements over information that is conveyed pragmatically and about what concepts should be deployed in the context at hand. We argue that neither of these features poses any obstacle to metalinguistic negotiations serving to express genuine, substantive disagreements that can be well worth engaging in. Contrary to what has been widely assumed in the literature, many normative and evaluative disputes—among ordinary speakers and even among philosophers themselves—may be of exactly this type, a conclusion with important consequences for both the subject matter and the methodology of metanormative theory.

In this paper I argue against one variety of contextualism about aesthetic predicates such as “beautiful.” Contextualist analyses of these and other predicates have been subject to several challenges surrounding disagreement. Focusing on one kind of contextualism— individualized indexical contextualism —I unpack these various challenges and consider the responses available to the contextualist. The three responses I consider are as follows: giving an alternative analysis of the concept of disagreement ; claiming that speakers suffer from semantic blindness; and (...) claiming that attributions of beauty carry presuppositions of commonality. I will argue that none of the available strategies gives a response which both satisfactorily explains all of the disagreement -data and is plausible independent of significant evidence in favor of contextualism. I conclude that individualized indexical contextualism about the aesthetic is untenable, although this does not rule out alternative contextualist approaches to the aesthetic. (shrink)

This paper approaches the current epistemological debate on peer disagreement from a neo-Pyrrhonian perspective, thus adopting a form of skepticism which is more radical than those discussed in the literature. It makes use of argumentative strategies found in ancient Pyrrhonism both to show that such a debate rests on problematic assumptions and to block some maneuvers intended to offer an efficacious way of settling a considerable number of peer disputes. The essay takes issue with three views held in the (...) peer disagreement debate: there is an objective fact of the matter about at least most controversial questions; we possess theory-neutral evidence bearing on those questions which grants us access to the truth of the matter; and many peer controversies are resolved by attending to which disputant has correctly evaluated the objective evidence. With respect to the first two views, it is argued that the belief in both objective facts and theory-neutral evidence is subject to fierce dispute, and should not therefore be taken for granted in the discussion of peer disagreement. As for the third view, it is argued that from either a first- or a third-person perspective, there seems to be epistemic symmetry between the disputants which makes it necessary to suspend judgment.

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

Moral disagreement is widely held to pose a threat for metaethical realism and objectivity. In this paper I attempt to understand how it is that moral disagreement is supposed to present a problem for metaethical realism. I do this by going through several distinct (though often related) arguments from disagreement, carefully distinguishing between them, and critically evaluating their merits. My conclusions are rather skeptical: Some of the arguments I discuss fail rather clearly. Others supply with a challenge (...) to realism, but not one we have any reason to believe realism cannot address successfully. Others beg the question against the moral realist, and yet others raise serious objections to realism, but ones that—when carefully stated—can be seen not to be essentially related to moral disagreement. Arguments based on moral disagreement itself have almost no weight, I conclude, against moral realism. (shrink)

What ought one to do, epistemically speaking, when faced with a disagreement? Faced with this question, one naturally hopes for an answer that is principled, general, and intuitively satisfying. We want to argue that this is a vain hope. Our claim is that a satisfying answer will prove elusive because of non-transparency: that there is no condition such that we are always in a position to know whether it obtains. When we take seriously that there is nothing, including our (...) own minds, to which we have assured access, the familiar project of formulating epistemic norms is destabilized. In this paper, we will show how this plays out in the special case of disagreement. But we believe that a larger lesson can ultimately be extracted from our discussion: namely, that non-transparency threatens our hope for fully satisfying epistemic norms in general. (shrink)

Many have maintained that the nature and extent of religious disagreement ought to shake our confidence in our religious or explicitly irreligious beliefs, leading us to be religious skeptics. This chapter argues that the most plausible ‘conciliatory’ view of disagreement does not lend support to religious skepticism. ‘Strong’ conciliatory views that say that one’s response to a disagreement should always be entirely determined by dispute-independent reasons are implausible. The only plausible conciliationism is a moderate version that holds (...) that one’s partisan reasoning about a disagreement is undermined only when one has sufficiently strong dispute-independent reasons for trusting the views of one’s disputants. But systems of religious belief often have certain features that make it unlikely that this moderate conciliationism will require a significant degree of conciliation when it is applied to religious disputes.

The paper confronts the disagreement argument for relativism about matters of taste, defending a specific form of contextualism. It is first considered whether the disagreement data might manifest an inviariantist attitude speakers pre-reflectively have. Semantic and ontological enlightenment should then make the impressions of disagreement vanish, or at least leave them as lingering ineffectual Müller-Lyer-like illusions; but it is granted to relativists that this does not fully happen. López de Sa’s appeal to presuppositions of commonality and Sundell’s (...) appeal to metalinguistic disagreement are discussed, and it is argued that, although they help to clarify the issues, they do not fully explain why such impressions remain under enlightenment. To do it, the paper develops a suggestion that other writers have made, that the lingering impression of disagreement is a consequence of a practical conflict, appealing to dispositions to practical coordination that come together with presuppositions of commonality in axiological matters.

I offer a new theory of faultless disagreement, according to which truth is absolute (non-relative) but can still be non-objective. What's relative is truth-aptness: a sentence like ‘Vegemite is tasty’ (V) can be truth-accessible and bivalent in one context but not in another. Within a context in which V fails to be bivalent, we can affirm that there is no issue of truth or falsity about V, still disputants, affirming and denying V, were not at fault, since, in their (...) context of assertion V was bivalent. This theory requires a theory of assertion that is a form of cognitive expressivism. (shrink)

The authors argue in favor of the “nonconciliation” (or “steadfast”) position concerning the problem of peer disagreement. Throughout the paper they place heavy emphasis on matters of phenomenology—on how things seem epistemically with respect to the net import of one’s available evidence vis-à-vis the disputed claim p, and on how such phenomenology is affected by the awareness that an interlocutor whom one initially regards as an epistemic peer disagrees with oneself about p. Central to the argument is a nested (...) goal/sub-goal hierarchy that the authors claim is inherent to the structure of epistemically responsible belief-formation: pursuing true beliefs by pursuing beliefs that are objectively likely given one’s total available evidence; pursuing this sub-goal by pursuing beliefs that are likely true (given that evidence) relative to one’s own deep epistemic sensibility; and pursuing this sub-sub-goal by forming beliefs in accordance with one’s own all-in, ultima facie, epistemic seemings.

Epistemic peer disagreement raises interesting questions, both in epistemology and in philosophy of science. When is it reasonable to defer to the opinion of others, and when should we hold fast to our original beliefs? What can we learn from the fact that an epistemic peer disagrees with us? A question that has received relatively little attention in these debates is the value of epistemic peer disagreement—can it help us to further epistemic goals, and, if so, how? We (...) investigate this through a recent case in paleoanthropology: the debate on the taxonomic status of Homo floresiensis remains unresolved, with some authors arguing the fossils represent a novel hominin species, and others claiming that they are Homo sapiens with congenital growth disorders. Our examination of this case in the recent history of science provides insights into the value of peer disagreement, indicating that it is especially valuable if one does not straightaway defer to a peer’s conclusions, but nevertheless remains open to a peer’s evidence and arguments.

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

When speakers utter conflicting moral sentences, it seems clear that they disagree. It has often been suggested that the fact that the speakers disagree gives us evidence for a claim about the semantics of the sentences they are uttering. Specifically, it has been suggested that the existence of the disagreement gives us reason to infer that there must be an incompatibility between the contents of these sentences. This inference then plays a key role in a now-standard argument against certain (...) theories in moral semantics. In this paper, we introduce new evidence that bears on this debate. We show that there are moral conflict cases in which people are inclined to say both that the two speakers disagree and that it is not the case at least one of them must be saying something incorrect. We then explore how we might understand such disagreements. As a proof of concept, we sketch an account of the concept of disagreement and an independently motivated theory of moral semantics which, together, explain the possibility of such cases. (shrink)

This article brings together two sets of data that are rarely discussed in concert; namely, disagreement and testimony data. I will argue that relativism yields a much more elegant account of these data than its major rival, contextualism. The basic idea will be that contextualists can account for disagreement data only by adopting principles that preclude a simple account of testimony data. I will conclude that, other things being equal, we should prefer relativism to contextualism. In making this (...) comparative point, I will also defend self-standing relativist accounts of disagreement and testimony data. (shrink)

According to Eric Olson, the Thinking Animal Argument (TAA) is the best reason to accept animalism, the view that we are identical to animals. A novel criticism has been advanced against TAA, suggesting that it implicitly employs a dubious epistemological principle. I will argue that other epistemological principles can do the trick of saving the TAA, principles that appeal to recent issues regarding disagreement with peers and experts. I conclude with some remarks about the consequence of accepting these modified (...) principles, drawing out some general morals in defending animalism. (shrink)

Disagreement is a hot topic in epistemology. A fast-growing literature centers around a dispute between the ‘steadfast’ view, on which one may maintain one’s beliefs even in the light of disagreement with epistemic peers who have all the same evidence, and the ‘conciliationist’ view, on which such disagreement requires a revision of attitudes. In this paper, however, I argue that there is less separating the main rivals in the debate about peer disagreement than is commonly thought. (...) The extreme versions of both views are clearly indefensible, while more moderate versions of the views converge on the idea that how much revision of belief is called for by an instance of peer disagreement varies from case to case. Those tempted by this diagnosis are sometimes pessimistic about the prospects for giving a unified account which clearly predicts when more or less extensive revisions will be called for. By contrast, in this paper I give an account that aspires to such unity and predictive power, centering on the notion of the net resilience of your estimate of your own reliability against your estimate of your interlocutor’s reliability. The view I present thus amounts to a new, moderate theory of how one should respond to disagreement. I argue that ultimately, when we weaken conciliationism and the steadfast view to account for exception cases and to make them adequately plausible, they end up converging on the moderate view I present. Much of the seeming disagreement about disagreement is, then, illusory. (shrink)

In this short paper I survey recent contextualist answers to the challenge from disagreement raised by contemporary relativists. After making the challenge vivid by means of a working example, I specify the notion of disagreement lying at the heart of the challenge. The answers are grouped in three categories, the first characterized by rejecting the intuition of disagreement in certain cases, the second by conceiving disagreement as a clash of non-cognitive attitudes and the third by relegating (...) disagreement at the pragmatic level. For each category I present several important variants and raise some (general) criticisms. The paper is meant to offer a quick introduction to the current contextualist literature on disagreement and thus a useful tool for further research. (shrink)

The phenomenon of disagreement has recently been brought into focus by the debate between contextualists and relativist invariantists about epistemic expressions such as ‘might’, ‘probably’, indicative conditionals, and the deontic ‘ought’. Against the orthodox contextualist view, it has been argued that an invariantist account can better explain apparent disagreements across contexts by appeal to the incompatibility of the propositions expressed in those contexts. This paper introduces an important and underappreciated phenomenon associated with epistemic expressions — a phenomenon that we (...) call reversibility. We argue that the invariantist account of disagreement is incompatible with reversibility, and we go on to show that reversible sentences cast doubt on the putative data about disagreement, even without assuming invariantism. Our argument therefore undermines much of the motivation for invariantism, and provides a new source for constraints on the proper explanation of purported data about disagreement. (shrink)

We often get evidence concerning the reliability of our own thinking about some particular matter. This “higher-order evidence” can come from the disagreement of others, or from information about our being subject to the effects of drugs, fatigue, emotional ties, implicit biases, etc. This paper examines some pros and cons of two fairly general models for accommodating higher-order evidence. The one that currently seems most promising also turns out to have the consequence that epistemic akrasia should occur more frequently (...) than is sometimes supposed. But it also helps us see why this might not be a bad thing. (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.

This paper considers John Doris, Stephen Stich, Alexandra Plakias, and colleagues’ recent attempts to utilize empirical studies of cross-cultural variation in moral judgment to support a version of the argument from disagreement against moral realism. Crucially, Doris et al. claim that the moral disagreements highlighted by these studies are not susceptible to the standard ‘diffusing’ explanations realists have developed in response to earlier versions of the argument. I argue that plausible hypotheses about the cognitive processes underlying ordinary moral judgment (...) and the acquisition of moral norms, when combined with a popular philosophical account of moral inquiry—the method of reflective equilibrium—undercut the anti-realist force of the moral disagreements that Doris et al. describe. I also show that Stich's recent attempt to provide further theoretical support for Doris et al.'s case is unsuccessful. (shrink)

How should an agent revise her epistemic state in the light of doxastic disagreement? The problems associated with answering this question arise under the assumption that an agent’s epistemic state is best represented by her degree of belief function alone. We argue that for modeling cases of doxastic disagreement an agent’s epistemic state is best represented by her confirmation commitments and the evidence available to her. Finally, we argue that given this position it is possible to provide an (...) adequate answer to the question of how to rationally revise one’s epistemic state in the light of disagreement. (shrink)

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)

On the shared-­ends account of close friendship, proper care for a friend as an agent requires seeing yourself as having important reasons to accommodate and promote the friend’s valuable ends for her own sake. However, that friends share ends doesn't inoculate them against disagreements about how to pursue those ends. This paper defends the claim that, in certain circumstances of reasonable disagreement, proper care for a friend as a practical and moral agent sometimes requires allowing her judgment to decide (...) what you are to do, even when you disagree with her judgment (and even when her judgment is in fact mistaken). In these instances, your friendship can make it the case that you may not act on your own practical and even moral judgments because, at those times, you have a duty as her close friend to defer to her judgments. As a result, treating your friend properly as a responsible agent can require that you assist her in committing what may in fact be serious moral wrongs. (shrink)

Conciliatory views of disagreement maintain that discovering a particular type of disagreement requires that one make doxastic conciliation. In this paper I give a more formal characterization of such a view. After explaining and motivating this view as the correct view regarding the epistemic significance of disagreement, I proceed to defend it from several objections concerning higher - order evidence made by Thomas Kelly.

The fact of moral disagreement when conjoined with Conciliationism, an independently attractive view about the epistemic significance disagreement, seems to entail moral skepticism. This worries those who like Conciliationism, the independently attractive view, but dislike moral skepticism. Others, equally inclined against moral skepticism, think this is a reductio of Conciliationism. I argue that they are both wrong. There is no reductio and nothing to worry about.

In this paper I argue for a version of the Total Evidence view according to which the rational response to disagreement depends upon one's total evidence. I argue that perceptual evidence of a certain kind is significantly weightier than many other types of evidence, including testimonial. Furthermore, what is generally called "The Uniqueness Thesis" is actually a conflation of two distinct principles that I dub "Evidential Uniqueness" and "Rationality Uniqueness." The former principle is likely true but the latter almost (...) certainly false. Seeing why the Rationality Uniqueness fails opens the door to seeing how mutual reasonable disagreement is possible even among those who share the same evidence. (shrink)

It is often suggested that disagreement among scientific experts is a reason not to trust those experts, even about matters on which they are in agreement. In direct opposition to this view, I argue here that the very fact that there is disagreement among experts on a given issue provides a positive reason for non-experts to trust that the experts really are justified in their attitudes towards consensus theories. I show how this line of thought can be spelled (...) out in three distinct frameworks for non-deductive reasoning, viz. Bayesian Confirmation Theory, Inference to the Best Explanation, and Inferential Robustness Analysis. (shrink)

Some have argued that the possibility of faultless disagreement gives relativist semantic theories an important explanatory advantage over their absolutist and contextualist rivals. Here I combat this argument, focusing on the specific case of aesthetic discourse. My argument has two stages. First, I argue that while relativists may be able to account for the possibility of faultless aesthetic disagreement, they nevertheless face difficulty in accounting for the intuitive limits of faultless disagreement. Second, I develop a new non-relativist (...) theory which can account for the full range of data regarding faultless disagreement. This view—‘Humean Absolutism’—integrates two of Hume’s central principles from Of the Standard of Taste into a truth-conditional framework, resulting in a non-bivalent theory of aesthetic truth. I argue that Humean Absolutism can underwrite the possibility of faultless disagreement whilst retaining reasonable limits around the phenomenon. I close by relating this positive account of faultless disagreement to broader issues concerning the cognitive role of truth-value gaps. -/- *NB - this is an unpublished paper and is no longer in progress.*.

The main aim of this paper is to propose that reflection is a performance that has epistemic value. This idea contains two parts: the first asserts that reflection has instrumental value. The second that reflective performance promotes an epistemic virtue that has final value. The first part is not controversial and most epistemologists would accept it. The second, however, asserts that there is a kind of epistemic good which can only be achieved through reflection. There is much controversy in this. (...) Reflection is understood here as a performance, an activity in which the person examines the evidence, content and reliability of their own beliefs. This performance may lead to different results, but if someone is capable of critically reflecting on their own beliefs in skeptical-dialectic contexts, whatever the results, this performance will produce positive epistemic states – contrary to people who, in the face of skeptical challenges, simply decide to remain intellectually immobile, maintaining a cowardly, arrogant or dogmatic position. The critical spirit with which someone discusses opinions in the context of dialectical disagreement, submitting them to the scrutiny of reason (that is, to the arguments for or against), is virtuous and has epistemic value. The consequence of this performance, the epistemic preference, has a final value, since deliberations based on free judgment have final value. (shrink)

What different relativist claims about a given domain are to be distinguished? Which of them is best placed to account for intuitive facts about disagreement in that domain? In a recent paper in this journal, ‘Indexical Relativism versus Genuine Relativism’ (2004), Max Kölbel distinguishes two forms of relativism, andargues that one of them, indexical relativism, faces problems in accounting for disagreement. In the first part of this discussion I present my own taxonomy of relativist positions in a given (...) domain, which is based on David Lewis’s 1980 essay, and I compare it with Kölbel’s and other recent suggestions. In the second part, I argue that the presuppositional defence of indexical relativism against related objections that I have elaborated elsewhere is also effective against Kölbel’s recent charges.

In the debate between contextualism and relativism about predicates of taste, the challenge from disagreement (the objection that contextualism cannot account for disagreement in ordinary exchanges involving such predicates) has played a central role. This paper investigates one way of answering the challenge consisting on appeal to certain, less focused on, uses of predicates of taste. It argues that the said thread is unsatisfactory, in that it downplays certain exchanges that constitute the core disagreement data. Additionally, several (...) arguments to the effect that the exchanges in question don’t amount to disagreement are considered and rejected. (shrink)

What sort of doxastic response is rational to learning that one disagrees with an epistemic peer who has evaluated the same evidence? I argue that even weak general recommendations run the risk of being incompatible with a pair of real epistemic phenomena, what I call evidential attenuation and evidential amplification. I focus on a popular and intuitive view of disagreement, the equal weight view. I take it to state that in cases of peer disagreement, a subject ought to (...) end up equally confident that her own opinion is correct as that the opinion of her peer is. I say why we should regard the equal weight view as a synchronic constraint on (prior) credence functions. I then spell out a trilemma for the view: it violates what are intuitively correct updates (also leading to violations of conditionalisation), it poses implausible restrictions on prior credence functions, or it is non-substantive. The sorts of reasons why the equal weight view fails apply to other views as well: there is no blanket answer to the question of how a subject should adjust her opinions in cases of peer disagreement.

The problem of multi-peer disagreement concerns the reasonable response to a situation in which you believe P1 … Pn and disagree with a group of ‘epistemic peers’ of yours, who believe ∼P1 … ∼Pn, respectively. However, the problem of multi-peer disagreement is a variant on the preface paradox; because of this the problem poses no challenge to the so-called ‘steadfast view’ in the epistemology of disagreement, on which it is sometimes reasonable to believe P in the face (...) of peer disagreement about P. After some terminology is defined (§1), Peter van Inwagen's challenge to the steadfast view will be presented (§2). The preface paradox will then be presented and diagnosed (§3), and it will be argued that van Inwagen's challenge relies on the same principle that generates the preface paradox (§4). The reasonable response to multi-peer disagreement will be discussed (§5), and an objection addressed (§6). (shrink)

In some cases of disagreement it seems that neither party is at fault or making a mistake. This phenomenon, so-called faultless disagreement, has recently been invoked as a key motivation for relativist treatments of domains prone to such disagreements. The conceivability of faultless disagreement therefore appears incompatible with traditional realists semantics. This paper examines recent attempts to accommodate faultless disagreement without giving up on realism. We argue that the accommodation is unsatisfactory. However, the examination highlights that (...) “faultless” is multiply ambiguous. The more overarching purpose is to examine the consequences of this—more generally, how to think about faultless disagreement. (shrink)

One of Mill’s main arguments for free speech springs from taking disagreement as an epistemically valuable resource for fallible thinkers. Contemporary conciliationist treatments of disagreement spring from the same motivation, but end up seeing the epistemic implications of disagreement quite differently. Conciliationism also encounters complexities when transposed from the 2-person toy examples featured in the literature to the public disagreements among groups that give the issue much of its urgency. Group disagreements turn out to be in some (...) ways more powerful defeaters of rational belief, even when opposing groups are comparable in size and epistemic credentials. And conciliationism also shows us why determining the rational response to these disagreements can in certain cases (e.g. politics) be a particularly difficult and nuanced matter. (shrink)

While many philosophers have agreed that evidence of disagreement is a kind of higher-order evidence, this has not yet resulted in formally precise higher-order approaches to the problem of disagreement. In this paper, we outline a simple formal framework for determining the epistemic significance of a body of higher-order evidence, and use this framework to motivate a novel interpretation of the popular “equal weight view” of peer disagreement—we call it the Variably Equal Weight View (VEW). We show (...) that VEW differs from the standard Split the Difference (SD) interpretation of the equal weight view in almost all cases of peer disagreement, and use our formal framework to explain why SD has seemed attractive but is in fact misguided. A desirable feature of VEW, we argue, is that it gives rise to plausible instances of synergy—an effect whereby the parties to a disagreement should become more (or less) confident in the disputed proposition than any of them were prior to disagreement. Lastly, we show how VEW may be generalized to cases of non-peer disagreement. (shrink)

In this essay I try to motivate and formulate the main epistemological questions to ask about the phenomenon of religious disagreement. I will not spend much time going over proposed answers to those questions. I address the relevance of the recent literature on the epistemology of disagreement. I start with some fiction and then, hopefully, proceed with something that has at least a passing acquaintance with truth.

Allan Gibbard () argues that the term ‘meaning’ expresses a normative concept, primarily on the basis of arguments that parallel Moore's famous Open Question Argument. In this paper I argue that Gibbard's evidence for normativity rests on idiosyncrasies of the Open Question Argument, and that when we use related thought experiments designed to bring out unusual semantic intuitions associated with normative terms we fail to find such evidence. These thought experiments, moreover, strongly suggest there are basic requirements for a theory (...) of meaning incompatible with Gibbard's ultimate goal of providing an expressivist account of meaning-related concepts. I conclude by considering a possible way in which meaning could be normative, consistent with the intuitions about disagreement; but this form of normativism about meaning appears incompatible with Gibbard's expressivism.

This chapter defends a version of the indexical contextualist form of moderate relativism: the attempt to endorse appearances of faultless disagreement within the framework in which a sentence at a context at the index of the context determines its appropriate truth-value. Many object that any such an indexical proposal would fail to account for intuitions of (genuine) disagreement as revealed in ordinary disputes in the domain. The defence from this objection exploits presuppositions of commonality to the effect that (...) the addressee is relevantly like the speaker of the context. (shrink)

This chapter has two sections, each focusing on a distinct way in which ethical disagreement and variations in ethical judgment matter for theories of ethical thought and talk. In the first section, we look at how the variation poses problems for both cognitivist and non-cognitivist ways of specifying the nature of ethical judgments. In the second, we look at how disagreement phenomena have been taken to undermine cognitivist accounts, but also at how the seeming variation in cognitive and (...) non-cognitive contents between parties of deep ethical disagreement challenges both cognitivist and non-cognitivist accounts of disagreement itself.

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)

Conciliatory theories of disagreement require that one lower one’s confidence in a belief in the face of disagreement from an epistemic peer. One question about which people might disagree is who should qualify as an epistemic peer and who should not. But when putative epistemic peers disagree about epistemic peerhood itself, then Conciliationism makes contradictory demands and paradoxes arise.

In the recent philosophy of language literature there is a debate over whether contextualist accounts of the semantics of various terms can accommodate intuitions of disagreement in certain cases involving those terms. Relativists such as John MacFarlane have claimed that this motivates adopting a form of relativist semantics for these terms because the relativist can account for the same data as contextualists but doesn’t face this problem of disagreement (MacFarlane 2005, 2007 and 2009). In this paper I focus (...) on the case of epistemic predicates and I argue that on a certain assumption about what is involved in assessing an utterance the epistemic contextualist can solve her problem of disagreement. This undercuts a motivation for epistemic relativism. (shrink)

This is a short essay that presents what I take to be the main questions regarding the epistemology of disagreement.
