Aesthetic subjectivism takes the truth of aesthetic judgments to be relative to the individual making that judgment. Despite widespread suspicion, however, this does not mean that one cannot be wrong about such judgments. Accordingly, this does not mean that one cannot gain higher-order evidence of error and fallibility that bears on the rationality of the aesthetic judgment in question. In this paper, we explain and explore these issues in some detail.

The Uniqueness Thesis (U), according to Richard Feldman and Roger White, says that for a given set of evidence E and a proposition P, only one doxastic attitude about P is rational given E. Luis Rosa has recently provided two counterexamples against U which are supposed to show that even if there is a sense in which choosing between two doxastic attitudes is arbitrary, both options are equally and maximally rational. Both counterexamples work by exploiting the idea that ‘ought implies (...) can’ and trying to spell out situations in which some inferences are beyond the capabilities of some reasoners. I argue that on a descriptive account of doxastic rationality, questions of whether ‘epistemic ought implies can’ can be bracketed and that at least one of the inferential moves that Rosa describes in his cases is irrational. I further argue that a descriptive account of doxastic rationality is the appropriate notion of rationality that is to be considered when evaluating U. If my argument for a descriptive account of rationality is successful, then we have reason to revise our use of the term rationality to fit this descriptive understanding. (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.

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

This paper has two aims. The first is critical: it argues that our mainstream epistemology of disagreement does not have the resources to explain what goes wrong in cases of group-level epistemic injustice. The second is positive: we argue that a functionalist account of group belief and group justification delivers an account of the epistemic peerhood relation between groups that accommodates minority and oppressed groups, and diagnoses the epistemic injustice cases correctly as cases of unwarranted belief on the part of (...) the oppressor group.

This paper examines the debate between permissive and impermissive forms of Bayesianism. It briefly discusses some considerations that might be offered by both sides of the debate, and then replies to some new arguments in favor of impermissivism offered by Roger White. First, it argues that White’s (Oxford studies in epistemology, vol 3. Oxford University Press, Oxford, pp 161–186, 2010) defense of Indifference Principles is unsuccessful. Second, it contends that White’s (Philos Perspect 19:445–459, 2005) arguments against permissive views do not (...) succeed. (shrink)

The first step in responding to the challenge of external world skepticism is to get clear on the structure of the skeptic’s argument. The most prominent varieties of skeptical arguments either rely on closure principles or underdetermination principles. The relationship between these two sorts of arguments is contentious. Some argue that these arguments can independently motivate skepticism. Others argue that they are really equivalent. I argue that although these two arguments are distinct, their independence is not as obvious as some (...) have thought. The fact that these arguments are not equivalent is important because skeptical arguments that appeal to underdetermination principles cannot be refuted by simply denying closure. So, the strategy for responding to skepticism offered by Nozick/Dretske does not seem an adequate solution. (shrink)

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)

Jim Joyce argues for two amendments to probabilism. The first is the doctrine that credences are rational, or not, in virtue of their accuracy or “closeness to the truth” (1998). The second is a shift from a numerically precise model of belief to an imprecise model represented by a set of probability functions (2010). We argue that both amendments cannot be satisfied simultaneously. To do so, we employ a (slightly-generalized) impossibility theorem of Seidenfeld, Schervish, and Kadane (2012), who show that (...) there is no strictly proper scoring rule for imprecise probabilities. -/- The question then is what should give way. Joyce, who is well aware of this no-go result, thinks that a quantifiability constraint on epistemic accuracy should be relaxed to accommodate imprecision. We argue instead that another Joycean assumption — called strict immodesty— should be rejected, and we prove a representation theorem that characterizes all “mildly” immodest measures of inaccuracy.

In this paper, I develop and respond to a novel objection to Conciliatory Views of disagreement. Having first explained Conciliationism and the problem of divine hiddenness, I develop an objection that Conciliationism exacerbates the problem of divine hiddenness. According to this objection, Conciliationism increases God’s hiddenness in both its scope and severity, and is thus incompatible with God’s existence (or at least make God’s existence quite improbable). I respond to this objection by showing that the problem of divine hiddenness is (...) not made any worse by Conciliationism. (shrink)

In this article, I propose, defend, and apply a principle for applied ethics. According to this principle, we should exercise moral caution, at least when we can. More formally, the principle claims that if you should believe or suspend judgment that doing an action is a serious moral wrong, while knowing that not doing that action is not morally wrong, then you should not do that action. After motivating this principle, I argue that it has significant application in applied ethics. (...) The application to applied ethics comes by way of the epistemic significance of disagreement. Though such a principle has perhaps a number of applications in applied ethics, my focus here is limited to the question of whether it is morally permissible to eat animals for pleasure. (shrink)

An introduction to the debate of the epistemic significance of peer disagreement. This article examines the epistemic significance of peer disagreement. It pursues the following questions: (1) How does discovering that an epistemic equal disagrees with you affect your epistemic justification for holding that belief? (e.g., does the evidence of it give you a defeater for you belief?) and (2) Can you rationally maintain your belief in the face of such disagreement? This article explains and motivates each of the central (...) positions, including steadfast views and conciliatory views of peer disagreement, while at the same time raising challenges for each of them. It concludes by speculating about new directions that the debate will take. (shrink)

In this paper I explore an epistemic asymmetry that sometimes occurs regarding the moral status of alternative actions. I argue that this asymmetry is significant and has ramifications for what it is morally permissible to do. I then show how this asymmetry often obtains regarding three moral issues: vegetarianism, abortion, and charitable giving. In doing so, I rely on the epistemic significance of disagreement and the existence of moral controversy about these issues.

What is the relationship between faith and evidence? It is often claimed that faith requires going beyond evidence. In this paper, I reject this claim by showing how the moral demands to have faith warrant a person in maintaining faith in the face of counter-evidence, and by showing how the moral demands to have faith, and the moral constraints of evidentialism, are in clear tension with going beyond evidence. In arguing for these views, I develop a taxonomy of different ways (...) of irrationally going beyond evidence and contrast this with rational ways of going against evidence. I then defend instances of having a moral demand to have faith, explore how this stands in tension with going beyond and against evidence, and develop an argument for the claim that faith involves a disposition to go against, but not beyond evidence.

Sometimes a proposition is ‘opaque’ to an agent: he doesn't know it, but he does know something about how coming to know it should affect his or her credence function. It is tempting to assume that a rational agent's credence function coheres in a certain way with his or her knowledge of these opaque propositions, and I call this the ‘Opaque Proposition Principle’. The principle is compelling but demonstrably false. I explain this incongruity by showing that the principle is ambiguous: (...) the term ‘know’ as it appears in the principle can be interpreted in two different ways, as either basic-know or super-know. I use this distinction to construct a plausible version of the principle, and then to similarly construct plausible versions of the Reflection Principle and the Sure-Thing Principle. (shrink)

A considerable literature has grown up around the claim of Uniqueness, according to which evidence rationally determines belief. It is opposed to Permissivism, according to which evidence underdetermines belief. This paper highlights an overlooked third possibility, according to which there is no rational doxastic attitude. I call this 'Nihilism'. I argue that adherents of the other two positions ought to reject it but that it might, nevertheless, obtain at least sometimes.

It is sometimes claimed that conciliatory views on disagreement ultimately lead to either global or widespread scepticism. This is deemed to be a serious problem for conciliationism either because scepticism of either kind is a patently untenable stance or because it poses a serious threat to our intellectual and social lives. In this paper, I first argue that the alleged untenability of both types of scepticism is far from being obvious and should therefore be established rather than taken for granted, (...) and then that those who reject them because of the threat they pose surprisingly confuse pragmatic reasons with epistemic reasons. (shrink)

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. (shrink)

An objection that has been raised to the conciliatory stance on the epistemic significance of peer disagreement known as the Equal Weight View is that it is self-defeating, self-undermining, or self-refuting. The proponent of that view claims that equal weight should be given to all the parties to a peer dispute. Hence, if one of his epistemic peers defends the opposite view, he is required to give equal weight to the two rival views, thereby undermining his confidence in the correctness (...) of the Equal Weight View. It seems that the same objection could be leveled against those who claim to suspend judgment in the face of pervasive unresolvable disagreements, as do the Pyrrhonian skeptics. In this paper, I explore the kind of response to the objection that could be offered from a neo-Pyrrhonian perspective, with the aim of better understanding the intriguing character of Pyrrhonian skepticism.

Many epistemologists endorse a view I call “evidence essentialism:” if e is evidence of h, for some agent at some time, then necessarily, e is evidence of h, for any agent at any time. I argue that such a view is only plausible if we ignore cognitive diversity among epistemic agents, i.e., the fact that different agents have different—sometimes radically different—cognitive skills, abilities, and proclivities. Instead, cognitive diversity shows that evidential relations are contingent and relative to cognizers. This is especially (...) obvious in extreme cases and in connection with epistemic defeat, but it is also very plausibly true of ordinary agents, and regarding prima facie justification. (shrink)

In this paper, I raise two questions about epistemic commitments, and thus, indirectly, about our epistemic agency. Can we rationally defend such commitments when challenged to do so? And if so, how?

The conception of responsibility for beliefs typically assumed in the literature mirrors the practices ofaccountabilityfor actions. In this paper, I argue that this trend leaves a part of what it is to be responsible unduly neglected, namely the practices ofattributability.After offering a diagnosis for this neglect, I bring these practices into focus and develop a virtue-theoretic framework to vindicate them. I then investigate the specificity of the belief case and conclude by resisting two challenges, namely that attributability cannot amount to (...) genuine responsibility and that it can be reduced to a sort of accountability. (shrink)

In this paper, I provide a novel explanationist framework for thinking about peer disagreement that solves many of the puzzles regarding disagreement that have troubled epistemologists over the last two decades. Explanationism is the view that a subject is justified in believing a proposition just in case that proposition is part of the best explanation of that subject’s total evidence. Applying explanationism to the problem of peer disagreement yields the following principle: in cases of peer disagreement, the thing that the (...) subjects ought to believe is the thing that is the best explanation of their total evidence, where part of their evidence is the fact that they happen to find themselves in disagreement with an epistemic peer. In what follows, I show how to understand and apply this core idea. (shrink)

There have been recent calls to expand contemporary analytic philosophy of religion beyond the oft implicitly assumed Christian tradition. Instead of exploring moral reasons to expand the discipline, I argue that there are strong epistemic reasons to favour diversifying the philosophy of religion. Increasing diversity is likely to increase disagreement, and there are epistemic benefits to be gained from the existence of disagreement. I argue that such considerations quite clearly apply to the philosophy of religion, and as such that there (...) are epistemic reasons to diversify the field. I conclude by offering a number of practical steps we can take towards achieving this end which are relatively easy to implement. (shrink)

In the epistemology of disagreement literature an underdeveloped argument defending the claim that an agent need not conciliate when she becomes aware of epistemic peer disagreement is based on the idea that there are epistemic benefits to be gained from disagreement. Such benefits are unobtainable if an agent conciliates in the face of peer disagreement. I argue that there are good reasons to embrace this line of argument at least in inquiry-related contexts. In argumentation theory a deep disagreement occurs when (...) there is a disagreement between fundamental frameworks. According to Robert J. Fogelin disagreements between fundamental frameworks are not susceptible to rational resolution. Instead of evaluating this claim I argue that deep disagreements can lead to epistemic benefits, at least when inquiry is in view. Whether rational resolution is possible in cases of deep disagreements, their existence turns out to be epistemically beneficial. I conclude by examining whether this line of argument can be taken beyond research-related contexts.Dans la littérature sur l'épistémologie du désaccord, un argument sous-développé pour une approche non conciliatoire se fonde sur l'idée qu'il y a des bénéfices épistémiques à tirer du désaccord. De tels bénéfices sont impossibles à obtenir si un agent se concilie face au désaccord avec ses pairs, du moins dans les contextes liés à la recherche. Dans la théorie de l'argumentation, un désaccord profond se produit lorsqu'il y a un désaccord entre des propositions cadres. Je soutiens que des désaccords profonds peuvent mener à des avantages épistémiques, du moins dans le contexte de la recherche. Que la résolution rationnelle soit ou non possible en cas de désaccord profond, leur existence s'avère être bénéfique sur le plan épistémologique. (shrink)

The paper presents a new argument for epistemic permissivism. The version of permissivism that we defend is a moderate version that applies only to explicit doxastic attitudes. Drawing on Yalcin’s framework for modeling such attitudes, we argue that two fully rational subjects who share all their evidence, prior beliefs, and epistemic standards may still differ in the explicit doxastic attitudes that they adopt. This can happen because two such subjects may be sensitive to different questions. Thus, differing intellectual interests can (...) yield failures of uniqueness. This is not a merely pragmatic phenomenon. (shrink)

Michael Bergmann seeks to motivate his externalist, proper function theory of epistemic justification by providing three objections to the mentalism and mentalist evidentialism characteristic of nonexternalists such as Richard Feldman and Earl Conee. Bergmann argues that (i) mentalism is committed to the false thesis that justification depends on mental states; (ii) mentalism is committed to the false thesis that the epistemic fittingness of an epistemic input to a belief-forming process must be due to an essential feature of that input, and, (...) relatedly, that mentalist evidentialism is committed to the false thesis that the epistemic fittingness of doxastic response B to evidence E is an essential property of B–E; and (iii) mentalist evidentialism is “unmotivated”. I object to each argument. The argument for (i) begs the question. The argument for (ii) suffers from the fact that mentalist evidentialists are not committed to the consequences claimed for them; nevertheless, I show that there is, in the neighborhood, a substantive dispute concerning the nature of doxastic epistemic fittingness. That dispute involves what I call “Necessary Fittingness”, the view that, necessarily, exactly one (at most) doxastic attitude ( belief , or disbelief , or suspension of judgment ) toward a proposition is epistemically fitting with respect to a person’s total evidence at any time. Reflection on my super-blooper epistemic design counterexamples to Bergmann’s proper function theory reveals both the plausibility of Necessary Fittingness and a good reason to deny (iii). Mentalist evidentialism is thus vindicated against the objections. (shrink)

In a recent work, Walter Carnielli and Abilio Rodrigues present an epistemically motivated interpretation of paraconsistent logic. In their view, when there is conflicting evidence with regard to a proposition A (i.e. when there is both evidence in favor of A and evidence in favor of ￢A) both A and ￢A should be accepted without thereby accepting any proposition B whatsoever. Hence, reasoning within their system intends to mirror, and thus, should be constrained by, the way in which we reason (...) about evidence. In this article we will thoroughly discuss their position and suggest some ways in which this project can be further developed. The aim of the paper is twofold. On the one hand, we will present some philosophical critiques to the specific epistemic interpretation of paraconsistent logic proposed by Carnielli & Rodrigues. First, we will contend that Carnielli & Rodrigues’s interpretation implies a thesis about what evidence rationally justifies to accept or believe, called Extreme Permissivism, which is controversial among epistemologists. Second, we will argue that what agents should do, from an epistemic point of view, when faced with conflicting evidence, is to suspend judgment. On the other hand, despite these criticisms we do not believe that the epistemological motivation put forward by Carnielli & Rodrigues is entirely wrong. In the last section, we offer an alternative way in which one might account for the epistemic rationality of accepting contradictions and, thus, for an epistemic understanding of paraconsistency, which leads us to discuss the notion of diachronic epistemic rationality. (shrink)

The uniqueness thesis states that for any body of evidence and any proposition, there is at most one rational doxastic attitude that an epistemic agent can take toward that proposition. Permissivism is the denial of uniqueness. Perhaps the most popular form of permissivism is what I call the Epistemic Standard View, since it relies on the concept of epistemic standards. Roughly speaking, epistemic standards encode particular ways of responding to any possible body of evidence. Since different epistemic standards may rationalize (...) different doxastic states on the same body of evidence, this view gives us a form of permissivism if different agents can have different epistemic standards. Defenders of the ESV, however, have not paid sufficient attention to what it means to have a particular epistemic standard. I argue that any theory of epistemic standard possession must satisfy two criteria to adequately address the broader needs of the ESV. The first criterion is the normative criterion: a theory of standard-possession should explain why agents are rationally required to form beliefs in accordance with their own epistemic standard, rather than any other standard. The second criterion is the applicability criterion: a theory of standard-possession should rule that agents have the epistemic standards we intuitively think they have. I then argue that no extant theories of standard-possession can satisfy both these criteria. I conclude by diagnosing why these criteria are so hard to jointly satisfy. Defenders of the ESV are thus left with a serious obstacle to forming a complete and plausible version of their view. (shrink)

Rationality is intrapersonally permissive just in case there are multiple doxastic states that one agent may be rational in holding at a given time, given some body of evidence. One way for intrapersonal permissivism to be true is if there are epistemic supererogatory beliefs—beliefs that go beyond the call of epistemic duty. Despite this, there has been almost no discussion of epistemic supererogation in the permissivism literature. This paper shows that this is a mistake. It does this by arguing that (...) the most popular ways of responding to one of the major obstacles to any intrapersonally permissive all fall prey to the same problem. This problem is most naturally solved by positing a category of epistemically supererogatory belief. So intrapersonal epistemic permissivists should embrace epistemic supererogation. (shrink)

Though there is a wide and varied literature on ethical supererogation, there has been almost nothing written about its epistemic counterpart, despite an intuitive analogy between the two fields. This paper seeks to change this state of affairs. I will begin by showing that there are examples which intuitively feature epistemically supererogatory doxastic states. Next, I will present a positive theory of epistemic supererogation that can vindicate our intuitions in these examples, in an explanation that parallels a popular theory of (...) ethical supererogation. Roughly, I will argue that a specific type of epistemic virtue—the ability to creatively think up plausible hypotheses given a body of evidence—is not required of epistemic agents. Thus, certain exercises of this virtue can result in supererogatory doxastic states. In presenting this theory, I will also show how thinking about epistemic supererogation can provide us a new way forward in the debate about the uniqueness thesis for epistemic rationality. (shrink)

Permissivism about rationality is the view that there is sometimes more than one rational response to a given body of evidence. In this paper I discuss the relationship between permissivism, deference to rationality, and peer disagreement. I begin by arguing that—contrary to popular opinion—permissivism supports at least a moderate version of conciliationism. I then formulate a worry for permissivism. I show that, given a plausible principle of rational deference, permissive rationality seems to become unstable and to collapse into unique rationality. (...) I conclude with a formulation of a way out of this problem on behalf of the permissivist. (shrink)

Robert Aumann presents his Agreement Theorem as the key conditional: “if two people have the same priors and their posteriors for an event A are common knowledge, then these posteriors are equal” (Aumann, 1976, p. 1236). This paper focuses on four assumptions which are used in Aumann’s proof but are not explicit in the key conditional: (1) that agents commonly know, of some prior μ, that it is the common prior; (2) that agents commonly know that each of them updates (...) on the prior by conditionalization; (3) that agents commonly know that if an agent knows a proposition, she knows that she knows that proposition (the “K K” principle); (4) that agents commonly know that they each update only on true propositions. It is shown that natural weakenings of any one of these strong assumptions can lead to countermodels to Aumann’s key conditional. Examples are given in which agents who have a common prior and commonly know what probability they each assign to a proposition nevertheless assign that proposition unequal probabilities. To alter Aumann’s famous slogan: people can “agree to disagree”, even if they share a common prior. The epistemological significance of these examples is presented in terms of their role in a defense of the Uniqueness Thesis: If an agent whose total evidence is E is fully rational in taking doxastic attitude D to P, then necessarily, any subject with total evidence E who takes a different attitude to P is less than fully rational. (shrink)

Richard Feldman’s well-known principle about disagreement and evidence – usually encapsulated in the slogan, ‘evidence of evidence is evidence’, (EEE) – invites the question, what should a rational believer do when faced by such evidence, especially when the disagreement is with an epistemic peer? The question has been the subject of much controversy. However, it has been recently suggested both that the principle is subject to counterexamples and that it is trivial. If either is the case, the question of what (...) to do in the face of evidence of evi- dence becomes less pressing. We contend that even if one or the other of these suggestions is right about (EEE) as a general principle about evidence, they leave it untouched insofar as it plays a role in the debates about the rational way to respond to disagreement and, in particular, to disagreement by an epistemic peer. This is because in such cases the evidence about which one has evidence and which is supposed to provide evidence against one's belief is the mere fact of someone’s disagreeing, rather than something that is related to the content of the proposition about which the parties disagree. We go on to argue that, so understood, the principle is false. (shrink)

This paper considers two questions. First, what is the scope of the Equal Weight View? Is it the case that meeting halfway is the uniquely rational method of belief-revision in all cases of known peer disagreement? The answer is no. It is sometimes rational to maintain your own opinion in the face of peer disagreement. But this leaves open the possibility that the Equal Weight View is indeed sometimes the uniquely rational method of belief revision. Precisely what is the skeptical (...) import of this fact; is it the case that some form of skepticism triumphs in such cases? The answer to this question is also no. As it turns out, the situations in which it is most plausible that the Equal Weight view is a rational requirement are the ones in which meeting halfway with a disagreeing peer brings you closer to, and not farther from, knowledge. I argue for these theses in a novel way; by looking at the comparative reliability of belief- invariance and meeting halfway using measures of reliability for degrees of belief, and by drawing normative conclusions from such results. The conclusions here can have the effect of reframing the entire debate in the epistemology of disagreement. (shrink)

Some philosophers argue that non-presentist A-theories problematically imply that we cannot know that this moment is present. The problem is usually presented as arising from the combination of the A-theoretic ideology of a privileged presentness and a non-presentist ontology. The goal of this essay is to show that the epistemic problem can be rephrased as a pessimistic induction. By doing so, I will show that the epistemic problem, in fact, stems from the A-theoretic ideology alone. Hence, once it is properly (...) presented, the epistemic problem presents a serious threat to all A-theories. (shrink)

This paper seeks to widen the dialogue between the “epistemology of peer disagreement” and the epistemology informed by Wittgenstein’s last notebooks, later edited as On Certainty. The paper defends the following theses: not all certainties are groundless; many of them are beliefs; and they do not have a common essence. An epistemic peer need not share all of my certainties. Which response to a disagreement over a certainty is called for, depends on the type of certainty in question. Sometimes a (...) form of relativism is the right response. Reasonable, mutually recognized peer disagreement over a certainty is possible.—The paper thus addresses both interpretative and systematic issues. It uses Wittgenstein as a resource for thinking about peer disagreement over certainties. (shrink)

A common worry about moral conciliationism is that it entails at best uncertainty about many of our moral beliefs and at worst epistemological moral scepticism. Against this worry, I argue that moral conciliationism saves us from epistemological moral scepticism and enables us to be confident in many of our moral beliefs. First, I show that only taking disagreements seriously as a threat to our beliefs allows us to utilise agreements in support of our beliefs (call this symmetry). Next, I argue (...) that utilising moral agreements as an epistemic resource allows moral conciliationism to resist the potentially worrisome reduction in confidence of our moral beliefs. Taking the relevance of moral agreement into account, I argue that it is anti-conciliationism that must meet the challenge of epistemological moral scepticism. For this, I suggest that moral inquiry is best understood as a collective endeavour. If so, then agreement on our moral judgments is required to justify the confidence we have in many of our moral beliefs. However, by symmetry, this appeal is possible only if one accepts the conciliatory attitude towards disagreements. Hence, accepting, rather than rejecting moral conciliationism, is the way out of moral scepticism. (shrink)

In recent years, epistemologists have devoted enormous attention to this question: what should happen when two epistemic peers disagree about the truth-value of some proposition? Some have argued that that in all such cases, both parties are rationally required to revise their position in some way. Others have maintained that, in at least some cases, neither party is rationally required to revise her position. In this paper, I examine a provocative and under-appreciated argument for the latter view due to Elgin (...) Disagreement, Oxford University Press, Oxford, pp 53–68, 2010; The Philosopher’s Magazine, fourth quarter, pp 77–82, 2012; True enough, MIT Press, Cambridge, 2017; in: Johnson Voicing dissent: the ethics and epistemology of making disagreement public, Routledge, New York, pp 10–21, 2018). I defend it against a series of objections, and I then identify some fruitful ways in which her view could be developed further. (shrink)

Scientific disputes about how often different processes or patterns occur are relative frequency controversies. These controversies occur across the sciences. In some areas—especially biology—they are even the dominant mode of dispute. Yet they depart from the standard picture of what a scientific controversy is like. In fact, standard philosophical accounts of scientific controversies suggest that relative frequency controversies are irrational or lacking in epistemic value. This is because standard philosophical accounts of scientific controversies often assume that in order to be (...) rational, a scientific controversy must reach a resolution and be about a scientifically interesting question. Relative frequency controversies rarely reach a resolution, however, and some scientists and philosophers are skeptical that these controversies center on scientifically interesting questions. In this paper, I provide a novel account of the epistemic contribution that relative frequency controversies make to science. I show that these controversies are rational in the sense of furthering the epistemic aims of the scientific communities in which they occur. They do this despite rarely reaching a resolution, and independent of whether the controversies are about scientifically interesting questions. This means that assumptions and about what is required for a controversy to be rational are wrong. Controversies do not need to reach a resolution in order to be rational. And they do not need to be about anything scientifically interesting in order to make valuable epistemic contributions to science. (shrink)

Nico Silins has proposed and defended a form of Liberalism about perception that, he thinks, is a good compromise between the Dogmatism of Jim Pryor and others, and the Conservatism of Roger White, Crispin Wright, and others. In particular, Silins argues that his theory can explain why having justification to believe the negation of skeptical hypotheses is a necessary condition for having justification to believe ordinary propositions, even though (contra the Conservative) the latter is not had in virtue of the (...) former. I argue that Silins's explanation is unsuccessful, and hence that we should prefer either White/Wright-style Conservatism (which can explain this necessary condition) or Pryor-style Dogmatism (which denies that this is a necessary condition).

The Uniqueness Thesis holds, roughly speaking, that there is a unique rational response to any particular body of evidence. We first sketch some varieties of Uniqueness that appear in the literature. We then discuss some popular views that conflict with Uniqueness and others that require Uniqueness to be true. We then examine some arguments that have been presented in its favor and discuss why permissivists find them unconvincing. Last, we present some purported counterexamples that have been raised against Uniqueness and (...) discuss some possible reasons why proponents of Uniqueness might find these similarly unconvincing.

In this essay, I present a straightforward counterexample to the Uniqueness Thesis, which holds, roughly speaking, that there is a unique rational response to any particular body of evidence.

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)

Toleranz wird für gewöhnlich als eine Einstellung definiert, die sich aus Akzeptanz und Ablehnung gegenüber der tolerierten Praxis zusammensetzt. In einem Aufsatz in dieser Zeitschrift hat Achim Lohmar dieses klassische Verständnis von Toleranz angegriffen und einen alternativen Toleranzbegriff stark gemacht. Ich werde argumentieren, dass Lohmars Analyse von Toleranz verfehlt ist, und zeigen, wie sich der klassische Toleranzbegriff gegen Lohmars Kritik verteidigen lässt. Dennoch ist Lohmars Kritik nicht uninteressant. Denn obwohl Lohmars begriffliche Kritik unzutreffend ist, lässt sich auf Lohmars Kritik aufbauend (...) ein inhaltliches Argument gegen die derzeit prominenteste Rechtfertigung von Toleranz formulieren, das Rawls’sche Argument von vernünftiger Meinungsverschiedenheit. Abschließend argumentiere ich gegen Lohmar, dass der personale Toleranzbegriff vom politischen nicht kategorial verschieden ist. (shrink)

Chalmers has argued that Bayesianism supports the existence of a priori truths, since it entails that scrutability conditionals are not rationally revisable. However, as we argue, Chalmers's arguments leave open that every proposition is rationally deniable, which would be devastating for large parts of his philosophical program. We suggest that Chalmers should appeal to well-known convergence theorems to argue that ideally rational subjects converge on the truth of scrutability conditionals. However, our discussion reveals that showing that these theorems apply in (...) effect requires assuming scrutability. Consequently, Bayesianism doesn't conflict with Chalmers's scrutability framework, but it doesn't support it, either. (shrink)

The preface paradox can be motivated by appealing to a plausible inference from an author’s reasonable assertion that her book is bound to contain errors to the author’s rational belief that her book contains errors. By evaluating and undermining the validity of this inference, I offer a resolution of the paradox. Discussions of the preface paradox have surprisingly failed to note that expressions of fallibility made in prefaces typically employ terms such as surely, undoubtedly, and bound to be. After considering (...) what these terms mean, I show that the motivating inference is invalid. Moreover, I argue that a closer consideration of our expressions of fallibility suggest that epistemically responsible authors would not be rational to believe that their books contain errors. I conclude by considering alternative expressions of fallibility that employ terms such as possible and probable, and discuss the role that expressions of fallibility play in conversation. (shrink)

Recently, Levinstein has offered two interesting arguments concerning epistemic norms and epistemic peer disagreement. In his first argument, Levinstein claims that a tension between Permissivism and steadfast attitudes in the face of epistemic peer disagreement generally leads us to conciliatory attitudes; in his second argument, he argues that, given an ‘extremely weak version of a deference principle,’ Permissivism collapses into Uniqueness. However, in this paper, I show that when we clearly distinguish among several types of Permissivism, Permissivism\, and Permissivism\), we (...) can see that any type of Permissivism fits well with steadfast attitudes. Further, even though Levinstein’s ‘extremely weak version of a deference principle’ does rule out a possibility for some types of Permissivism and Permissivism\), it is still compatible with the other type of Permissivism ), so we may regard at least that version of a deference principle as a viable position in connection with that particular type of permissive rationality.

Credal Conservatism says that an agent’s credal states should be conserved as far as possible when she undergoes a learning experience. Uniqueness says that for any given total evidence, there is a unique credal state that any agent with that total evidence should have. Epistemic Impartiality is the idea that there are no significant differences between intrapersonal and interpersonal rationality requirements when determining what credal states one ought to have for purposes of epistemic evaluation. I construe Epistemic Impartiality as a (...) meta-principle governing epistemic norms, and argue that it is compatible with Conservatism. Then I show that on the assumption of Epistemic Impartiality, Credal Conservatism is equivalent to Uniqueness. (shrink)
