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

This article deals with two questions: why would the way in which the neopyrronicle conducts his philosophical activity be more virtuous than his dogmatic, non-pyrrhic colleague does? And why would the result he achieves be more valuable? That said, my answer to the first question is that the way the neo-Pyrrhonian investigates is more virtuous because it seeks to deliberately avoid the vices of precipitation, arrogance and mental closure. Regarding the second question, I suggest that the outcome of the neopyronic (...) investigation, whatever it may be (even if it is not the truth) is more valuable because of the way he conducts his investigation.

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)

This paper introduces and motivates a solution to a dilemma from peer disagreement. Following Buchak (2021), I argue that peer disagreement puts us in an epistemic dilemma: there is reason to think that our opinions should both change and not change when we encounter disagreement with our epistemic peers. I argue that we can solve this dilemma by changing our credences, but not our beliefs in response to disagreement. I explain how my view solves the dilemma in question, and then (...) offer two additional arguments for it: one related to contents and attitudes, and another related to epistemic peerhood. (shrink)

This is an introduction to the volume The Epistemology of Group Disagreement (Routledge, forthcoming), (eds.) F. Broncano-Berrocal and J.A. Carter.

In this paper, I do three things. First, I say what I mean by a ‘companions in guilt’ argument in meta-ethics. Second, I distinguish between two kinds of argument within this family, which I call ‘arguments by entailment’ and ‘arguments by analogy’. Third, I explore the prospects for companions in guilt arguments by analogy. During the course of this discussion, I identify a distinctive variety of argument, which I call ‘arguments by absorption’. I argue that this variety of argument inherits (...) some of the weaknesses of standard arguments by analogy and entailment without obviously adding to their strength. (shrink)

If you retain your belief upon learning that a large number and percentage of your recognized epistemic superiors disagree with you, then what happens to the epistemic status of your belief? I investigate that theoretical question as well has the applied case of philosophical disagreement—especially disagreement regarding purely philosophical error theories, theories that do not have much empirical support and that reject large swaths of our most commonsensical beliefs. I argue that even if all those error theories are false, either (...) (a) the average philosopher’s true commonsensical beliefs are epistemically impoverished, or (b) a good portion of philosophy is bunk and philosophers should give up most of their error theories despite the fact that their supporting arguments are generally as good as or even better than other philosophical arguments. (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.

Our main aim is to discuss the topic of scientific controversies in the context of a recent issue that has been the centre of attention of many epistemologists though not of argumentation theorists or philosophers of science, namely the ethics of belief in face of rational disagreement. We think that the consideration of scientific examples may be of help in the epistemological debate on rational disagreement, making clear some of the deficiencies of the discussion as it has been produced until (...) now. Another central claim of our paper is that the common view according to which beliefs (and changes of beliefs) may exhibit and commonly exhibit a deontic status can be clarified in the light of Brandom’s approach to normative pragmatics and the pragmatic theories of argumentation that also have a normative character (here our example is van Eemeren’s pragma-dialectics). Our article highlights the similarities between both projects, similarities that to our knowledge were not noticed before. Finally, an important point of the article is that we need to take contextual elements into account in order to develop an adequate theory of disagreement. (shrink)

One explanation of rational peer disagreement is that agents find themselves in an epistemically permissive situation. In fact, some authors have suggested that, while evidence could be impermissive at the intrapersonal level, it is permissive at the interpersonal level. In this paper, I challenge such a claim. I will argue that, at least in cases of rational disagreement under full disclosure, there cannot be more interpersonal epistemically permissive situations than there are intrapersonal epistemically permissive situations. In other words, with respect (...) to cases of disagreement under full disclosure, I will argue that there is a necessary connection between interpersonal permissiveness and its intrapersonal counterpart. Specifically, I claim that a plausible principle of correct argumentation supports such a bridge. (shrink)

What is the relationship between Immodesty and Permissivism? For permissivists, epistemically rational agents are sometimes permitted to take incompatible doxastic attitudes towards P. Immodesty is a requirement governing our estimations or beliefs about our own credences and standards. If agents believe that their standards and credences are not among the most truth-conducive ones available to them, they are not immodest. Some philosophers think that Immodesty is incompatible with Intrapersonal Permissivism :41–56, 2014, J Philos 116:237–262, 2019). Others think that Immodesty can (...) be used to respond to some objections against Interpersonal Permissivism :193–218). In this paper, we argue that Immodesty neither supports nor disproves Permissivism. (shrink)

Conciliationism holds that disagreement of apparent epistemic peers often substantially undermines rational confidence in our opinions. Uniqueness principles say that there is at most one maximally rational doxastic response to any given batch of total evidence. The two views are often thought to be tightly connected. This paper distinguishes two ways of motivating conciliationism, and two ways that conciliationism may be undermined by permissive accounts of rationality. It shows how conciliationism can flourish under certain strongly permissive accounts of rationality. This (...) occurs when the motivation for conciliationism does not come from taking disagreement as evidence of one's own rational failings. However, divorcing the motive for conciliating from worries about rationality does not remove a feature of conciliationism that some find troubling: that conciliationism can lead to cases of “rational toxicity,” in which the most rational response to one's evidence involves violating some rational ideal.

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.

Douglas Diekema has argued that it is not the best interest standard, but the harm principle that serves as the moral basis for ethicists, clinicians, and the courts to trigger state intervention to limit parental authority in the clinic. Diekema claims the harm principle is especially effective in justifying state intervention in cases of religiously motivated medical neglect in pediatrics involving Jehovah’s Witnesses and Christian Scientists. I argue that Diekema has not articulated a harm principle that is capable of justifying (...) state intervention in these cases. Where disagreements over appropriate care are tethered to metaphysical disagreements, it is moral-metaphysical standards, rather than merely moral standards, that are needed to provide substantive guidance. I provide a discussion of Diekema’s harm principle to the broader end of highlighting an inconsistency between the theory and practice of secular bioethics when overriding religiously based medical decisions. In a secular state, ethicists, clinicians, and the courts are purportedly neutral with respect to moral-metaphysical positions, especially regarding those claims considered to be religious. However, the practice of overriding religiously based parental requests requires doffing the mantle of neutrality. In the search for a meaningful standard by which to override religiously based parental requests in pediatrics, bioethicists cannot avoid some minimal metaphysical commitments. To resolve this inconsistency, bioethicists must either begin permitting religiously based requests, even at the cost of children’s lives, or admit that at least some moral-metaphysical disputes can be rationally adjudicated.

I outline a dilemma for Derek Parfit’s project to vindicate moral realism. In On What Matters, Parfit argues that the best versions of three of the main moral traditions agree on a set of moral principles, which should make us more confident about the prospects of truth in ethics. I show that the result of this Convergence Argument can be interpreted in two ways. Either there remain three separate and deontically equivalent theories or there remains just one theory, the Triple (...) Theory. Both interpretations fail to deliver what Parfit is looking for. The first interpretation leads to a situation of underdetermination of theory choice that gives rise to a skeptical challenge. The second interpretation jettisons Parfit’s Conciliatory Project, that is, the reconciliation of the three moral traditions. The dilemma, I contend, is the result of Parfit failing to resolve two antithetical lines of thought. His search for the Trinity of moral theorizing must thus fail. (shrink)

Conciliationism faces a challenge that has not been satisfactorily addressed. There are clear cases of epistemically significant merely possible disagreement, but there are also clear cases where merely possible disagreement is epistemically irrelevant. Conciliationists have not yet accounted for this asymmetry. In this paper, we propose that the asymmetry can be explained by positing a selection constraint on all cases of peer disagreement—whether actual or merely possible. If a peer’s opinion was not selected in accordance with the proposed constraint, then (...) it lacks epistemic significance. This allows us to distinguish the epistemically significant cases of merely possible disagreement from the insignificant ones. (shrink)

I argue that reflection on philosophers who could have been working among us but aren’t can lead us to give up our philosophical beliefs.

With respect to many, if not most issues, there exist significant differences of opinion among individuals who seem to be equally knowledgeable and sincere. Individuals who apparently have access to the same information and are equally interested in the truth affirm incompatible perspectives on, for instance, significant social, political, and economic issues. Such diversity of opinion, though, is nowhere more evident than in the area of religious thought. On almost every religious issue, honest, knowledgeable people hold significantly diverse, often incompatible (...) beliefs. -/- Religious diversity of this sort can fruitfully be explored in many ways — for instance, from psychological, anthropological, or historical perspectives. The current discussion, however, will concern itself primarily with those key issues surrounding religious diversity with which philosophers, especially analytic philosophers of religion, are most concerned at present. Specifically, our discussion will focus primarily on the following questions: How pervasive is religious diversity? Does the reality of this diversity require a response? Can a person who acknowledges religious diversity remain justified in claiming just one perspective to be correct? If so, is it morally justifiable to attempt to convert others to a different perspective? Can it justifiably be claimed that only one religion offers a path into the eternal presence of God? The answers to such questions are not simply academic. They increasingly have great impact on how we treat others, both personally and corporately. (shrink)

Our interest in this paper is to drive a wedge of contention between two different programs that fall under the umbrella of “experimental philosophy”. In particular, we argue that experimental philosophy’s “negative program” presents almost as significant a challenge to its “positive program” as it does to more traditional analytic philosophy.

To what extent can we rely on others for information without such reliance becoming epistemically problematic? In this paper, this question is addressed in terms of a specific form of reliance: cognitive outsourcing. Cognitive outsourcing involves handing over (outsourcing) one’s information collection and processing (the cognitive) to others. The specific question that will be asked about such outsourcing is if there is an epistemic problem about cognitive outsourcing as such. To ask if there is an epistemic problem with x for (...) S is to ask if x is a problem for S’s ability to acquire true belief and avoid false belief. To ask if there is a problem for S with x as such is to ask if it is impossible to solve the problem for S while leaving x as is. I argue that, if we consider the five most plausible candidate epistemic problems raised by cognitive outsourcing—i.e., unreliability, gullibility, irrationality, dependency, and lack of epistemic autonomy—we see for each candidate that it is either not an epistemic problem, or not a problem about cognitive outsourcing as such.

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.

Verdejo, Víctor_A Puzzle about Disagreement.

When epistemic peers disagree, what should a virtuous arguer do? Several options have been defended in the recent literature on the epistemology of disagreement, which connects interestingly to the controversy launched by Fogelin’s famous paper on ‘deep disagreement.’ I will argue that Fogelin’s case is transformed by the new work on disagreement, and that when seen in that broader epistemological context ‘deep’ disagreement is much less problematic for argumentation theory than it once seemed.

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

This is the most comprehensive book ever published on philosophical methodology. A team of thirty-eight of the world's leading philosophers present original essays on various aspects of how philosophy should be and is done. The first part is devoted to broad traditions and approaches to philosophical methodology. The entries in the second part address topics in philosophical methodology, such as intuitions, conceptual analysis, and transcendental arguments. The third part of the book is devoted to essays about the interconnections between philosophy (...) and neighbouring fields, including those of mathematics, psychology, literature and film, and neuroscience.

Political epistemology is a newly flourishing area of philosophy, but there is no comprehensive overview to this burgeoning field. This chapter maps out the terrain of political epistemology, highlights some of the key questions and topics of this field, draws connections across seemingly disparate areas of work, and briefly situates this field within its historical and contemporary contexts.

Should we believe our controversial philosophical views? Recently, several authors have argued from broadly conciliationist premises that we should not. If they are right, we philosophers face a dilemma: If we believe our views, we are irrational. If we do not, we are not sincere in holding them. This paper offers a way out, proposing an attitude we can rationally take toward our views that can support sincerity of the appropriate sort. We should arrive at our views via a certain (...) sort of ‘insulated’ reasoning – that is, reasoning that involves setting aside certain higher-order worries, such as those provided by disagreement – when we investigate philosophical questions.

Two controversies exist regarding the appropriate characterization of hierarchical and adaptive evolution in natural populations. In biology, there is the Wright-Fisher controversy over the relative roles of random genetic drift, natural selection, population structure, and interdemic selection in adaptive evolution begun by Sewall Wright and Ronald Aylmer Fisher. There is also the Units of Selection debate, spanning both the biological and the philosophical literature and including the impassioned group-selection debate. Why do these two discourses exist separately, and interact relatively little? (...) We postulate that the reason for this schism can be found in the differing focus of each controversy, a deep difference itself determined by distinct general styles of scientific research guiding each discourse. That is, the Wright-Fisher debate focuses on adaptive process, and tends to be instructed by the mathematical modeling style, while the focus of the Units of Selection controversy is adaptive product, and is typically guided by the function style. The differences between the two discourses can be usefully tracked by examining their interpretations of two contested strategies for theorizing hierarchical selection: horizontal and vertical averaging.

Recently, a number of epistemologists (notably Feldman [2007], [2009] and White [2005], [2013]) have argued for the rational uniqueness thesis, the principle that any set of evidence permits only one rationally acceptable attitude toward a given proposition. In contrast, this paper argues for extreme rational permissivism, the view that two agents with the same evidence may sometimes arrive at contradictory beliefs rationally. This paper identifies different versions of uniqueness and permissivism that vary in strength and range, argues that evidential peers (...) with different interests need not rationally endorse all the same hypotheses, argues that evidential peers who weigh the theoretic virtues differently can sometimes rationally endorse contradictory conclusions, and finally defends the permissivist appeal to standards against objections in the works of Feldman and White.

Should we always engage in critical thinking about issues of public policy, such as health care, gun control, and LGBT rights? Michael Huemer (2005) has argued for the claim that in some cases it is not epistemically responsible to engage in critical thinking on these issues. His argument is based on a reliabilist conception of the value of critical thinking. This article analyzes Huemer's argument against the epistemic responsibility of critical thinking by engaging it critically. It presents an alternative account (...) of the value of critical thinking that is tied to the notion of forming and deploying a critical identity. And it develops an account of our epistemic responsibility to engage in critical thinking that is not dependent on reliability considerations alone. The primary purpose of the article is to provide critical thinking students, or those that wish to reflect on the value of critical thinking, with an opportunity to think metacritically about critical thinking by examining an argument that engages the question of whether it is epistemically responsible for one to engage in critical thinking.

Jacob Ross and Mark Schroeder argue that invariantist accounts of disagreement are incompatible with the phenomenon of reversibility. In this essay I develop a non-standard theory of propositional attitudes, which I call attitudinal relativism. Using the resources of attitudinal relativism, I articulate an invariantist account of disagreement that is compatible with reversibility.

When do we agree? The answer might once have seemed simple and obvious; we agree that p when we each believe that p. But from a formal epistemological perspective, where degrees of belief are more fundamental than beliefs, this answer is unsatisfactory. On the one hand, there is reason to suppose that it is false; degrees of belief about p might differ when beliefs simpliciter on p do not. On the other hand, even if it is true, it is too (...) vague; for what it is to believe simpliciter ought to be explained in terms of degrees of belief. This paper presents several possible notions of agreement, and corresponding notions of disagreement. It indicates how the findings are fruitful for the epistemology of disagreement, with special reference to the notion of epistemic peerhood. (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)

Philosophers of religion have taken the assumption for granted that the various religious traditions of the world have incompatible beliefs. In this paper, I will argue that this assumption is more problematic than has been generally recognized. To make this argument, I will discuss the implications of internal religious disagreement, an aspect of this issue that has been too often ignored in the contemporary debate. I will also briefly examine some implications of my argument for how one might respond to (...) the existence of religious diversity. (shrink)

The recent literature on the epistemology of disagreement focuses on the rational response question: how are you rationally required to respond to a doxastic disagreement with someone, especially with someone you take to be your epistemic peer? A doxastic disagreement with someone also confronts you with a slightly different question. This question, call it the epistemic trust question, is: how much should you trust our own epistemic faculties relative to the epistemic faculties of others? Answering the epistemic trust question is (...) important for the epistemology of disagreement because it sheds light on the rational response question. My main aim in this paper is to argue—against recent attempts to show otherwise—that epistemic self-trust does not provide a reason for remaining steadfast in doxastic disagreements with others. (shrink)

This paper provides a defence of the thesis that responsible belief is permissible rather than obliged belief. On the Uniqueness Thesis (UT), our evidence is always such that there is a unique doxastic attitude that we are obliged to have given that evidence, whereas the Permissibility Thesis (PT) denies this. After distinguishing several varieties of UT and PT, we argue that the main arguments that have been levied against PT fail. Next, two arguments in favour of PT are provided. Finally, (...) two motivations for PT are put forward by showing that PT is entailed by two views that are quite popular among theorists working on doxastic responsibility. If the arguments in this paper are successful, we not only have good reasons to prefer PT over UT, but also good reasons to think that the gap between the ways in which we are meant to normatively assess belief and action may not be as wide as has been thought. (shrink)

In this paper I take up the question of the nature of the doxastic attitudes we entertain while inquiring into some matter. Relying on a distinction between two stages of open inquiry, I urge to acknowledge the existence of a distinctive attitude of cognitive inclination towards a proposition qua answer to the question one is inquiring into. I call this attitude “hypothesis”. Hypothesis, I argue, is a sui generis doxastic attitude which differs, both functionally and normatively, from suspended judgement, full (...) belief, credences, and acceptance. In closing, I point to the epistemological significance of hypothesis. More specifically, I contend that holding an attitude of hypothesis enables us to respond rationally to peer disagreement, and I suggest that such an attitude offers a suitable articulation of the view, originally put forward by Philip Kitcher, that cognitive diversity in inquiry has epistemic benefits.

In this article we argue that philosophy can facilitate improvement in cross-disciplinary science. In particular, we discuss in detail the Toolbox Project, an effort in applied epistemology that deploys philosophical analysis for the purpose of enhancing collaborative, cross-disciplinary scientific research through improvements in cross-disciplinary communication. We begin by sketching the scientific context within which the Toolbox Project operates, a context that features a growing interest in and commitment to cross-disciplinary research (CDR). We then develop an argument for the leading idea (...) behind this effort, namely, that philosophical dialogue can improve cross-disciplinary science by effecting epistemic changes that lead to better group communication. On the heels of this argument, we describe our approach and its output; in particular, we emphasize the Toolbox instrument that generates philosophical dialogue and the Toolbox workshop in which that dialogue takes place. Together, these constitute a philosophical intervention into the life of CDR teams. We conclude by considering the philosophical implications of this intervention. (shrink)

Contemporary interpretations of Zhuangzi’s 莊子 philosophy as adumbrating a relativist position are legion. However, what is the scope and nature of the relativism that can be gleaned from a comprehensive analysis of relevant passages in the Zhuangzi? In this essay, I shall explain Zhuangzi’s alleged relativist position as motivated from a primary concern about disagreement. He in effect claims that since any disputant can foresee her assertion to be refuted by an opponent, the recourse to a higher tribunal in adjudicating (...) the debate is futile. The consequence of an apparent lack of justification for assertion is, in my opinion, what needs elucidation. For example, is “truth relativism” an apt label for the nature of assertion in a debate without the verdict of a judge? Or, is it more appropriate to shun the concept of truth altogether in our explanation? I deem the contemporary explanation of Zhuangzi’s relativism either trivializes disputation or fails to account for the difference between a claim’s being right and being acceptable. Hence, I shall argue that without the intrusion of a judge as an arbiter of truth, the kind of disputation Zhuangzi practices promulgates faultless disagreement, which does not appeal to the correctness of any perspective in a comparative or absolute sense. In this understanding, Zhuangzi’s advice of harmonizing with both right and wrong is indeed a viable alternative to relativism and dogmatism, both of which do not properly take heed of the point of disagreeing in a disputation.

Stephen Law has recently offered an argument against the rationality of certain religious beliefs that he calls the X-claim argument against religious beliefs. The argument purports to show that it is irrational to believe in the existence of extraordinary beings associated with religions. However, the X-claim argument is beset by certain ambiguities that, once resolved, leave the argument undifferentiated from two other common objections to the rationality of religious belief: the objection from religious diversity and the objection from unreliable sources. (...) And though the latter pose serious obstacles to the rationality of religious belief, the X-claim argument adds no further difficulty. (shrink)

This paper attends to two main tasks. First, I introduce the notion of perspectival disagreement in science. Second, I relate perspectival disagreement in science to the broader issue of realism about science: how to maintain realist ontological commitments in the face of perspectival disagreement among scientists? I argue that often enough perspectival disagreement is not at the level of the scientific knowledge claims but rather of the methodological and justificatory principles. I introduce and clarify the notion of ‘agreeing-whilst-perspectivally-disagreeing’ with an (...) episode from the history of modern physics: namely, how we came to agree about the electric charge as a minimal natural unit despite different scientific perspectives and associated data-to-phenomena inferences available for it in the period 1897–1906.

This paper argues for the following three claims. First, the Agrippan mode from disagreement does not play a secondary role in inducing suspension of judgment. Second, the Pyrrhonist is not committed to the criteria of justification underlying the Five Modes of Agrippa, which nonetheless does not prevent him from non-doxastically assenting to them. And third, some recent objections to Agrippan Pyrrhonism raised by analytic epistemologists and experimental philosophers fail to appreciate the Pyrrhonist's ad hominem style of argumentation and the real (...) challenge posed by the mode from disagreement.

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

In a situation of peer disagreement, peers are usually assumed to share the same evidence. However they might not share the same evidence for the epistemic system used to process the evidence. This synchronic complication of the peer disagreement debate suggested by Goldman (In Feldman R, Warfield T (eds) (2010) Disagreement. Oxford University Press, Oxford, pp 187–215) is elaborated diachronically by use of a simulation. The Hegselmann–Krause model is extended to multiple epistemic systems and used to investigate the role of (...) consensus and difference splitting in peer disagreement. I find that the very possibility of multiple epistemic systems downgrades the epistemic value of consensus and makes difference splitting a suboptimal strategy. (shrink)

Contributors to the recent disagreement debate have sought to provide a uniform response to cases in which epistemic peers disagree about the epistemic import of a shared body of evidence, no matter what kind of evidence they are disagreeing about. The varied cases addressed in the literature have included examples of disagreement about restaurant bills, court verdicts, weather forecasting, chess, morality, religious beliefs, and even disagreements about philosophical disagreements. The equal treatment of these varied cases has motivated the search for (...) a uniform response to peer disagreement wherever it is encountered. In this article I challenge this prevalent approach in the literature. I grant the notion of epistemic peer and accept that being a peer may amount to the same thing in different domains; nonetheless I contend that different domains appear to call for different responses to disagreement. I argue that the appropriate response to finding out about a disagreement with a peer is different in different domains. (shrink)

Contemporary Western culture is experiencing a heightened awareness of religious diversity. This article surveys a range of possible responses to such diversity, and distinguishes between responses that concern the salvation or moral transformation of persons (soteriological views) and those that concern the alethic or epistemic status of religious beliefs (doctrinal views). After providing a brief taxonomy of these positions and their possible relations to one another, the article focuses primarily on competing views about the truth and rationality of religious beliefs (...) (e.g., pluralism, exclusivism, and skepticism). Here a heavy emphasis is placed on arguments for and against the rationality and moral propriety of retaining one's religious beliefs in the face of disagreement. The article surveys some of the more prominent arguments from the literature on this topic and closes with suggestions for further research. (shrink)
