Several recent articles have weighed in on the question of whether moral philosophers can be counted as moral experts. One argument denying this has been rejected by both sides of the debate. According to this argument, the extent of disagreement in modern moral philosophy prevents moral philosophers from being classified as moral experts. Call this the Argument From Disagreement. In this article, I defend a version of AD. Insofar as practical issues in moral philosophy are characterized (...) by disagreement between moral philosophers who are more or less equally well credentialed on the issue, non-philosophers have no good reasons to defer to their views.

Disagreement has been grist to the mills of sceptics throughout the history of philosophy. Recently, though, some philosophers have argued that widespread philosophical disagreement supports a broad scepticism about philosophy itself. In this paper, I argue that the task for sceptics of philosophy is considerably more complex than commonly thought. The mere fact that philosophical methods fail to generate true majority views is not enough to support the sceptical challenge from disagreement. To avoid demanding (...) something that human reasoning cannot supply, sceptics must show that philosophers have sufficient overlap to resolve their disagreements in particular concrete cases.

This chapter discusses the nature and value of political disagreement, with reference to contemporary work in political philosophy. I will attempt to answer the following questions: Why do we disagree? Is political disagreement a good thing? Do we have a duty to disagree? Should we expect consensus or mere compromise in politics? When is civil disobedience a justified way to express disagreement with the law? Is consensus a threat to democracy?

Disagreement as we find it in both the history and the contemporary practice of philosophy is an inadequately understood phenomenon. In this paper I outline and motivate the problem of disagreement, arguing that "hard cases" of disagreement confront us with an unresolved, and seemingly unresolvable, challenge to the rationality of philosophical discourse, thereby raising the specter of a worri-some form of metaphilosophical skepticism. A variety of responses and attempted evasions are considered, though none are found to (...) be particularly satisfying: Thus, the specter remains unexorcised. El desacuerdo que encontramos tanto en la historia como en la práctica contemporánea de la filosofía es un fenómeno mal entendido. En este trabajo hago un esbozo y aduzco los motivos del problema del desacuerdo, argumentando que los "casos difíciles" de desacuerdo nos confrontan con un problema sin resolver y al parecer sin posibilidad de resolverse, que pone en duda la racionalidad del discurso filosófico, y con lo cual surge el espectro de una preocupante forma de escepticismo metafilosófico. Examino varias respuestas y tentativas de evasiones, aunque ninguna de ellas es particularmente satisfactoria. Así, el espectro sigue sin ser exorcizado. (shrink)

Modest pessimism about philosophical progress is the view that while philosophy may sometimes make some progress, philosophy has made, and can be expected to make, only very little progress (where the extent of philosophical progress is typically judged against progress in the hard sciences). The paper argues against recent attempts to defend this view on the basis of the pervasiveness of disagreement within philosophy. The argument from disagreement for modest pessimism assumes a teleological conception of (...) progress, according to which the attainment of true answers to the big philosophical questions, or knowledge of them, is the primary goal of philosophy. The paper argues that this assumption involves a misconception of the goal of philosophy: if philosophy has a primary goal, its goal is the understanding of philosophical problems rather than knowledge of answers to philosophical questions. Moreover, it is argued that if the primary goal of philosophy is such understanding, then widespread disagreement within philosophy does not indicate that philosophy makes little progress. (shrink)

In philosophy, as in many other disciplines and domains, stable disagreement among peers is a widespread and well-known phenomenon. Our intuitions about paradigm cases, e.g. Christensen's Restaurant Case, suggest that in such controversies suspension of judgment is rationally required. This would prima facie suggest a robust suspension of judgment in philosophy. But we are still lacking a deeper theoretical explanation of why and under what conditions suspension is rationally mandatory. In the first part of this paper I (...) will focus on this question. After a critical survey of some recent alternative approaches (diversity as a thread to the reliability, decision problem, acquisition of undercutting defeaters), I will argue that in fact discovering disagreement with an opponent provides me with a rebutting defeater, but only if some further non-trivial conditions are satisfied - among them my acknowledging her as my reliability peer. In the second part of the paper I will explore in more detail the skeptical implications this account has for philosophy. Here, I will defend two claims. First, skepticism about philosophy is mandatory only if the relevant peerness assumption can be justified. Second, in philosophy there is no basis available that would support the relevant peerness assumption. If this is correct, we are not forced into skepticism about philosophy and may rationally retain our philosophical beliefs even in the face of controversy. (shrink)

Philosophy is sometimes perceived as an abstract and nerdy discipline dealing with problems of its own creation in an isolated chamber of the Ivory Tower. And there is some truth to this view. But philosophy can help us deal with common problems, such as the disagreements we have in our everyday lives.

Set in the context of the current interest among Analytic philosophers in the “epistemology of disagreement,” this paper explores the meta-philosophical problem of philosophical incommensurability. Motivated by Nietzsche’s provocative remark about philosophy as prejudices and desires of the heart “sifted and made abstract,” the paper first outlines the contours of the problem and then traces it through a series of examples. Drawing largely on the tradition of phenomenology and philosophical hermeneutics, a broadly Continental response to this formidable problem (...) is suggested. Disagreement cannot be understood simply in terms of epistemological strategy, but needs to be regarded in a fundamentally hermeneutical light. (shrink)

Disagreement in philosophy is all-pervasive and irresolvable. There is almost no thesis in philosophy about which philosophers agree. In contrast to most contemporary accounts of philosophical disagreement, I argue that a significant proportion of philosophical disagreements are rooted in differences regarding values. A second thesis that I shall defend in this paper is that disagreements regarding values are not resolvable by argumentative means.

W.V.Quine and Philip Kitcher have both developed naturalistic approaches to the philosophy of science which are partially based on a skeptical view about the possibility of rational inquiry into certain questions of value. Nonetheless, both Quine and Kitcher do not wish to give up on the normative dimension of the philosophy of science. I argue that Kitcher's recent argument against the specification of the goal of science in terms of truth raises a problem for Quine's account of the (...) normative dimensions of the discipline. However Kitcher's alternative suggestion, that the goal of science is to be specified in terms of an ideal democratic procedure, does not escape this problem, given Kitcher's own limited skepticism about rational inquiry into certain questions of value.

My aim is to discuss some counterexamples to the following principle: -/- (P) Necessarily, for every proposition p, for every cognitive agent S and for every cognitive agent S*, if S believes that p and S* believes that ¬p, then either S makes a normative error or S* makes a normative error. -/- If we assume the identity between S and S*, then (P) regulates what I'm going to call psychological contradiction; conversely, if we assume the non-identity between S and (...) S*, then (P) regulates cases of disagreement. In trying to offer counterexamples, I will compare two different approaches: a three-valued approach and a relativist approach. I will argue that adopting the latter is preferable, since, contrary to the former, in offering counterexamples to (P) it does not commit us to hold the controversial metaphysical views that I will present in section 2. Furthermore, it allows us to propose genuine counterexamples not only in cases of syntactic disagreement, but also in cases of semantic and ontological disagreement. (shrink)

Disagreement is common: even informed, intelligent, and generally reasonable people often come to different conclusions when confronted with what seems to be the same evidence. Can the competing conclusions be reasonable? If not, what can we reasonably think about the situation? This volume examines the epistemology of disagreement. Philosophical questions about disagreement arise in various areas, notably politics, ethics, aesthetics, and the philosophy of religion: but this will be the first book focusing on the general epistemic (...) issues arising from informed disagreement. Ten leading philosophers offer specially written essays which together will offer a starting-point for future work on this topic. (shrink)

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)

When we first meet Kim Wexler in Better Call Saul we see someone who appears to offer a moral counterbalance to Jimmy McGill. She encourages him to stay within the boundaries of the law, and to stop committing trademark infringement to spite Howard from HHM, for example. With each season we get to know Kim better and gradually we see that Kim’s real objections to Jimmy’s lies and scams are often more practical than moral. However, there are a number of (...) occasions across the seasons of the show where there does seem to be a real conflict between Kim and Jimmy’s moral beliefs. Deep and seemingly irresolvable disagreement with others about moral matters is something we all experience in our lives. It may be a paradigmatic disagreement over whether abortion is morally permissible, or a disagreement over whether it’s always wrong to lie to a client. Cases of moral disagreement are especially troubling when the person who disagrees with us is someone who we take to be just as informed about the issue, smart, and open-minded. Are we justified in maintaining the same confidence in our belief after learning of our disagreement with someone just as capable of reasoning about the matter and just as informed? Should we suspend judgment about what the right view is? The same questions arise when the disagreement concerns nonmoral beliefs, such as whether some action poses too much risk to one’s career. In this chapter I will take a look at different answers to these questions through an examination of some disagreements between Kim and Jimmy and how they respond to them in the short term and in the long term. Some of the disagreements are primarily moral disagreements. Others are not clearly moral, but instead primarily about risks and career decisions. As we will see, whether we are justified in maintaining the same confidence in our belief upon discovering the disagreement may depend on the type of disagreement. (shrink)

Following Oliver Ramsbotham’s observation that conflict resolution and analysis have not taken radical disagreement seriously enough, and in light of his lament that he has not yet found an adequate philosophy of radical disagreement, this article claims that the philosophy of Alasdair MacIntyre provides some coreelements of any adequate philosophy of radical disagreement. MacIntyre’s theory suggests that the problem of radical disagreement is in fact more radical thanRamsbotham affirms. Ramsbotham’s account of the strategic (...) engagement of discourses (SED) approach is critiqued in light of MacIntyre’s diagnosis of radical disagreement, which calls into question its theoretical and philosophical basis. The main problem is held to be that of internal radical disagreement, which SED appears to skirt over. This is elucidated through a brief exploration of two philosophical approaches to moral-political disagreement in relation to Israeli peace activism and the Colombian conflict. (shrink)

People disagree frequently, about both objective and subjective matters. But while at least one party must be wrong in a disagreement about objective matters, it seems that both parties can be right when it comes to subjective ones: it seems that there can be faultless disagreements. But how is this possible? How can people disagree with one another if they are both right? And why should they? In recent years, a number of philosophers and linguists have argued that we (...) must become relativists about truth to understand faultless disagreements. This book shows that we can dispense with relativism. It combines a more standard semantics with a novel pragmatic theory to develop a superior approach. The book discusses both classic and recent literature in philosophy and linguistics. It provides a general introduction to the debate about the semantics and pragmatics of perspectival expressions, as well as an original contribution to the contemporary discussion. (shrink)

Religious disagreement is pervasive in contemporary life, both internationally and inside pluralistic societies. Understanding it requires understanding both what constitutes a religion and what constitutes genuine disagreement. To resolve religious disagreements, we need principles for rationally approaching them and standards for law-making that are fair to all citizens. This paper considers what sorts of evidences parties to a religious disagreement should present if they hope for resolution or at least mutual tolerance. The paper suggests some common ground (...) as a basis for communication and partial agreement on issues likely to divide the religious. It concludes with some ethical principles intended to help those who seek peaceful resolution of religious disagreements in the framework of pluralistic democracy. (shrink)

This paper examines the philosophy of Jean-Francois Lyotard in relation to the analytic philosophy of deep disagreement. It argues not just that his work has relevance for this debate, but that it offers a challenge to the ‘epistemic paradigm’ present in its academic literature, represented by the two most prominent sets of theories within it – the ‘fundamental epistemic principle’ and ‘hinge epistemology’ views, arguably most strongly represented by Michael Lynch and Duncan Pritchard, respectively. Focussing on Lyotard’s (...) text ‘The Differend’, I show how its conceptual framework and philosophy of language locates the cause of deep disagreement not in the epistemic realm, but in things which do not fully submit to epistemic evaluation: the radically incomplete and open nature of language, and our increasingly politically pluralistic world full of incommensurable differences that do not always admit of rational resolution. Lyotard’s work calls for us to conceptualize deep disagreements as problems of politics, not epistemology, and to find new ways of dealing with disagreements that do not force a solution on them (which often comes at the cost of one party being wronged, or worse) and to create new ways of speaking so that our collective conceptual resources can be increased to better deal with specific cases of dispute. Lyotard’s relevance for the philosophy of deep disagreement is also further discussed with references to Miranda Fricker’s work on ‘epistemic injustice’, which Lyotard, in a different vocabulary, is also concerned with and analyses in ‘The Differend’.

How should one react when one has a belief, but knows that other people—who have roughly the same evidence as one has, and seem roughly as likely to react to it correctly—disagree? This paper argues that the disagreement of other competent inquirers often requires one to be much less confident in one’s opinions than one would otherwise be.

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)

Religious communities often discourage disagreement with religious authorities, on the grounds that allowing it would be epistemically detrimental. I argue that this attitude is mistaken, because any social position in a community—including religious authority—comes with epistemic advantages as well as epistemic limitations. I argue that religious communities stand to benefit epistemically by engaging in disagreement with people occupying other social positions. I focus on those at the community’s margins and argue that religious marginalization is apt to yield religiously (...) important insights; so their disagreement with religious authorities should be encouraged.

Disagreement is one of the deepest and most pervasive topics in philosophy, arguably its very bedrock, and is an ever-increasing feature of politics, ethics, public policy, science and many other areas. Despite the omnipresence of disagreement, the topic itself has received relatively little sustained examination. In this outstanding handbook a team of international contributors examines the philosophy of disagreement and how it extends to debates in public policy and science. Comprising forty-one chapters by an international (...) team of contributors, the Handbook is divided into six clear parts: Philosophy of Disagreement Epistemology of Disagreement Disagreement about Science Moral Disagreement Disagreement in Politics Disagreement in Public Policy Within these sections key topics are examined, including: skepticism, truth, pluralism, feminist philosophy, experimental philosophy, epistemology of peer disagreement, rationality, intellectual virtue, relativism, realism, instrumentalism, scientific method and perspectivism. Ideal for those studying and researching philosophy, especially epistemology, ethics and philosophy of science, this handbook will also be of interest to those in related disciplines such as politics, social policy, and law.

I argue for the possibility of substantive aesthetic disagreements in which both parties speak truly. The possibility of such disputes undermines an argument mobilized by relativists such as Lasersohn (Linguist Philos 28:643–686, 2005) and MacFarlane (Philos Stud 132:17–31, 2007) against contextualism about aesthetic terminology. In describing the facts of aesthetic disagreement, I distinguish between the intuition of dispute on the one hand and the felicity of denial on the other. Considered separately, neither of those phenomena requires that there be (...) a single proposition asserted by one party to an aesthetic dispute and denied by the other. I suggest instead that many such disputes be analyzed as disputes over the selection or appropriateness of a contextually salient aesthetic standard. (shrink)

Global meta-philosophical skepticism (i.e. completely unrestricted skepticism about philosophy) based upon disagreement faces the problem of self-defeat since it undercuts its motivating conciliatory principle. However, the skeptic may easily escape this threat by adopting a more modest kind of skepticism, that will be called “extensive meta-philosophical skepticism”, i.e., the view that most of our philosophical beliefs are unjustified, except our beliefs in epistemically fundamental principles. As I will argue in this paper, this kind of skepticism is well-motivated, does (...) not undercut the conciliatory principle, but still poses a radical challenge to philosophy as a cognitive discipline. Moreover, I will argue that non-global skepticism that is still extensive undermines itself as well. The deeper reason for this is that this more modest kind of skepticism can only be motivated by the assumption that disagreement with philosophical peers is abundant and that we can identify peers only by relying on track-record arguments. But then one can argue for extensive meta-philosophical skepticism only if one presupposes that those philosophical beliefs that form the basis of track-record evaluations are justified. Here, the threat of self-defeat looms again. I will proceed by first defending the premises of this new anti-skeptical argument against standard objections from the literature. Second, I will show in more detail where the epistemic inconsistency arises in the argument for extensive meta-philosophical skepticism. I conclude with an assessment of the scope and the limits of my argument. (shrink)

In recent years, several philosophers have argued that their discipline makes no progress (or not enough in comparison to the “hard sciences”). A key argument for this pessimistic position appeals to the purported fact that philosophers widely and systematically disagree on most major philosophical issues. In this paper, we take a step back from the debate about progress in philosophy specifically and consider the general question: How (if at all) would disagreement within a discipline undermine that discipline’s progress? (...) We reject two arguments from disagreement to a lack of progress, and spell out two accounts of progress on which progress is compatible with disagreements that persist or increase over time. However, we also argue that disagreement can undermine our ability to tell which developments are progressive (and to what degree). So, while disagreement can indeed be a threat to progress, the precise nature of the threat has not been appreciated. (shrink)

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.

This paper presents a new solution to the problem of peer disagreement that distinguishes two principles of rational belief, here called probability and autonomy. When we discover that we disagree with peers, there is one sense in which we rationally ought to suspend belief, and another in which we rationally ought to retain our original belief. In the first sense, we aim to believe what is most probably true according to our total evidence, including testimony from peers and authorities. (...) In the second, we aim to base our beliefs only on objective evidence and argumentation, even if that lowers the probability of their being true. The first principle of rational belief tends to serve the short-term epistemic interests of individuals, while the second tends to serve the long-term epistemic interests of both individuals and groups. The best way to reconcile these principles in cases of peer disagreement is to associate them with two corresponding species of belief, here called perception and opinion. (shrink)

Suppose that you and I disagree about some non-straightforward matter of fact (say, about whether capital punishment tends to have a deterrent effect on crime). Psychologists have demonstrated the following striking phenomenon: if you and I are subsequently exposed to a mixed body of evidence that bears on the question, doing so tends to increase the extent of our initial disagreement. That is, in response to exactly the same evidence, each of us grows increasingly confident of his or her (...) original view; we thus become increasingly polarized as our common evidence increases. I consider several alternative models of how people reason about newly-acquired evidence which seems to disconfirm their prior beliefs. I then explore the normative implications of these models for the phenomenon in question. (shrink)

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

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)

The idea that there can be cases of faultless disagreement, cases of disagreement in which neither party is making a mistake, is frequently discussed in connection with relativist views in philosophy of language. My goal is to argue that we can make sense of faultless disagreement without being committed to any form of relativism if we recognise that disagreement sometimes involves attitudes other than belief, such as desires or preferences. Furthermore, this way of making sense (...) of faultless disagreement allows us to avoid some of the problems that have been raised in connection with relativist accounts of faultless disagreement.

In this chapter we explore the topic of logical disagreement. Though disagreement in general has attracted widespread philosophical interest, both in epistemology and philosophy of language, the general issues surrounding disagreement have only rarely been applied to logical disagreement in particular. Here, we develop some of the fascinating semantic and epistemological puzzles to which logical disagreement gives rise. In particular, after distinguishing between different types of logical disagreement, we explore some connections between logical (...) disagreements and deep disagreements over fundamental epistemic principles; we discuss several semantic puzzles that arise on various accounts of the meanings of logical terms; we investigate how such disagreements relate to Kripke’s so-called “Adoption Problem”; and we probe epistemological puzzles that arise from disagreements about logic in the light of central principles from the peer disagreement literature.

This book examines the ways in which reasonable people can disagree about the requirements of political morality. Christopher McMahon argues that there will be a 'zone of reasonable disagreement' surrounding most questions of political morality. Moral notions of right and wrong evolve over time as new zones of reasonable disagreement emerge out of old ones; thus political morality is both different in different societies with varying histories, and different now from what it was in the past. McMahon explores (...) this feature of his theory in detail and traces its implications for the possibility of making moral judgments about other polities, past or present. His study sheds light on an important and often overlooked aspect of political life, and will be of interest to a wide range of readers in moral and political philosophy and in political theory.

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.

According to the classical argument from moral disagreement, the existence of widespread or persistent moral disagreement is best explained by, and thus inductively supports the view that there are no objective moral facts. One of the most common charges against this argument is that it “overgeneralizes”: it implausibly forces its proponents to deny the existence of objective facts about certain matters of physics, history, philosophy, etc. as well (companions in guilt), or even about its own conclusion or (...) its own soundness (self-defeat). Is this overgeneralization charge justified? In this paper I argue that both overgeneralization objections are rather weak. The companions in guilt version very likely fails, and the self-defeat version more likely fails than not. This result gives us reason to consider the argument from moral disagreement more seriously than has recently been done. (shrink)

People disagree. Along with doubt, modesty and curiosity, disagreement is one of the most valuable assets reasoning beings can have. Disagreements give us alternatives. Sometimes we need to decide among alternatives. This paper is for such times; it addresses the development of a rational model for the resolution of disagreement. The goal is to reach rational agreement, or to reach the stage at which disagreement can be clearly described and turned over to rational consensus theories. A rarely (...) noticed problem with all such rational consensus models is that they do not provide for generating either rational agreement or clearly described disagreement before turning to procedures designed to produce consensus. One purpose of this paper is to close that gap. (shrink)

When theorising about disagreement, it is tempting to begin with a person's belief that p and ask what mental state one must have in order to disagree with it. This is the wrong way to go; the paper argues that people may also disagree with attitudes that are not beliefs. It then examines whether several existing theories of disagreement can account for this phenomenon. It argues that its own normative theory of disagreement gives the best account, and (...) so, given that there is good reason to believe disagreement without belief is possible, there is good reason to think that disagreement itself is normative.

Widespread moral disagreement raises ethical, epistemological, political, and metaethical questions. Is the best explanation of our widespread moral disagreements that there are no objective moral facts and that moral relativism is correct? Or should we think that just as there is widespread disagreement about whether we have free will but there is still an objective fact about whether we have it, similarly, moral disagreement has no bearing on whether morality is objective? More practically, is it arrogant to (...) stick to our guns in the face of moral disagreement? Must we suspend belief about the morality of controversial actions such as eating meat and having an abortion? And does moral disagreement affect the laws that we should have? For instance, does disagreement about the justice of heavily redistributive taxation affect whether such taxation is legitimate? In this thorough and clearly written introduction to moral disagreement and its philosophical and practical implications, Richard Rowland examines and assesses the following topics and questions: -/- How does moral disagreement affect what we should do and believe in our day-to-day lives? Epistemic peerhood and moral disagreements with our epistemic peers. Metaethics and moral disagreement. Relativism, moral objectivity, moral realism, and non-cognitivism. Moral disagreement and normative ethics. Liberalism, democracy, and disagreement. Moral compromise. Moral uncertainty. -/- Combining clear philosophical analysis with summaries of the latest research and suggestions for further reading, Moral Disagreement is ideal for students of ethics, metaethics, political philosophy, and philosophical topics that are closely related, such as relativism and scepticism. It will also be of interest to those in related disciplines such as public policy and philosophy of law. (shrink)

Th e present article reports a series of experiments designed to extend the empirical investigation of folk metaethical intuitions by examining how different kinds of ethical disagreement can impact attributions of objectivity to ethical claims.

It is often assumed that when one party felicitously rejects an assertion made by an- other party, the first party thinks that the proposition asserted by the second is false. This assumption underlies various disagreement arguments used to challenge contex- tualism about some class of expressions. As such, many contextualists have resisted these arguments on the grounds that the disagreements in question may not be over the proposition literally asserted. The result appears to be a dialectical stalemate, with no (...) independent method of determining whether any particular instance of disagreement is over the proposition literally asserted. In this paper, I propose an independent method for assessing whether a disagreement is about what’s literally asserted. Focusing on epistemic modals throughout, I argue that this method provides evidence that some epistemic modal disagreements are in fact not over the proposition literally asserted by the utterance of the epistemic modal sentence. This method provides a way to break the stalemate, and reveals a new data point for theories of epistemic modals to predict—that is, how there can be such modal disagreements. In the rest of the paper, I motivate a general theory of how to predict these kinds of disagreements, and then offer some brief remarks about how contextualist, relativist, and expressivist theories of epistemic modals might accommodate this new data point.

Lewisian reference magnetism about linguistic content determination [Lewis 1983 has been defended in recent work by Weatherson [2003] and Sider [2009], among others. Two advantages claimed for the view are its capacity to make sense of systematic error in speakers' use of their words, and its capacity to distinguish between verbal and substantive disagreements. Our understanding of both error and disagreement is linked to the role of usage and first order intuitions in semantics and in linguistic theory more generally. (...) I argue, partially on the basis of these more general considerations, that reference magnetism delivers implausible results. Specifically, I argue that the proponent of reference magnetism maintains her analysis of genuinely systematic error at the cost of an empirically unjustifiable error theory regarding ordinary usage. In response, I describe an alternative view of content determination—MUMPS, or Meaning is Use Minus Pragmatics—which is not committed to such error theories. Despite this advantage, MUMPS has high prima facie costs. On such a view, there is a great deal of variation in linguistic meaning across speakers and times. As a result, a large number of seemingly mistaken claims are analysed as expressing true propositions. Correspondingly, a large number of seemingly substantive disagreements are analysed as terminological. However, I argue that these consequences are not as costly as they seem. Despite appearances, MUMPS is consistent with objective, metaphysically realist adjudication of disagreements, even in cases where meanings are not shared and where both parties to a dispute speak truly. MUMPS thus allows for a more nuanced understanding of linguistic usage, change, and variation, without imposing a commitment to any form of metaphysical anti-realism. (shrink)

How much should your confidence in your beliefs be shaken when you learn that others – perhaps 'epistemic peers' who seem as well-qualified as you are – hold beliefs contrary to yours? This article describes motivations that push different philosophers towards opposite answers to this question. It identifies a key theoretical principle that divides current writers on the epistemology of disagreement. It then examines arguments bearing on that principle, and on the wider issue. It ends by describing some outstanding (...) questions that thinking about this issue raises. (shrink)

Deep disagreement is a disagreement about epistemic principles, pertaining to the methods of justification and argumentation. Relying on Ludwig Wittgenstein’s conceptual metaphor of “hinges,” researchers arrive at the conclusion that deep disagreement cannot be resolved. This conclusion leads to relativism in the theory of argumentation. The aim of the article is to show that in the situation of deep disagreement it is theoretically possible to ascertain which of the positions of the participants of the argument has (...) a better epistemic status, and hence, is argumentatively virtuous.

This paper defends a particular view of explaining reasonable disagreement: the Conceptual View. The Conceptual View is the idea that reasonable disagreements are caused by differences in the way reasonable people use concepts in a cognitive process to make moral and political judgements. But, that type of explanation is caught between either an explanatory weakness or an unparsimonious and potentially self-undermining theory of concepts. When faced with deep disagreements, theories on the Conceptual View either do not have the resources (...) to explain them, or can only explain them by committing to a completely new theory of concepts where all moral and political concepts are a unique type of concept. This paper shows how the Conceptual View can avoid this dilemma by adopting what I dub the ‘Metalinguistic Strategy’ for explaining reasonable disagreement. The Metalinguistic Strategy uses recent innovations in the philosophy of language on metalinguistic negotiation to explain reasonable disagreements whether they be ordinary or deep disagreements as genuine disagreements whilst maintaining our ordinary ideas about concepts.

This paper describes and analyses the experience of the participants of an undergraduate reading group on ‘The Wartime Quartet’. In the first section, I explain the set-up of the reading group. In the second section, I discuss what the participants shared and the trends we noticed in our experiences as women and marginalised genders studying undergraduate philosophy In the third section, I explain why the philosophy of the Quartet was itself vital to our development and how it enabled (...) us to begin critically engaging with the material presented in our courses. My fourth section introduces a phenomenon I call disassociated disagreement (DD) and uses testimonies from former members of the reading group to illustrate why this phenomenon is central to understanding the confusion that sometimes presents in students of philosophy. I then discuss a strategy for combating DD and illustrate how students’ seeming confusion can provide a pathway to unique and insightful philosophical perspectives. I conclude by situating my discussion within the broader framework of research into women's representation in philosophy and close by arguing that the concept of DD can be a potent tool for encouraging more philosophy undergraduates who belong to marginalised groups to pursue further study.

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.

It is a common intuition that at least in some cases disagreement has skeptical consequences: the participants are not justified in persisting in their beliefs. I will argue that the currently popular non-dialectical and individualistic accounts of justification, such as evidentialism and reliabilism, cannot explain this intuition and defend the dialectical conception of justification that can explain it. I will also argue that this sort of justification is a necessary condition of knowledge by relying on Craig's genealogy of the (...) concept of knowledge. I will then respond to the accusation that the dialectical conception leads to radical skepticism. My response is partly concessive. It does lead to skepticism in areas where controversy prevails, such as philosophy, politics and religion, but this sort of skepticism is quite intuitive. Finally, I deal with the objection that my defense of skepticism about philosophy is self-refuting. (shrink)

It has been claimed that epistemic peers, upon discovering that they disagree on some issue, should give up their opposing views and ‘split the difference’. The present paper challenges this claim by showing, with the help of computer simulations, that what the rational response to the discovery of peer disagreement is—whether it is sticking to one’s belief or splitting the difference—depends on factors that are contingent and highly context-sensitive.Keywords: Peer disagreement; Computer simulations; Opinion dynamics; Hegselmann–Krause model; Social epistemology.
