The thesis that agents should calibrate their beliefs in the face of higher-order evidence—i.e., should adjust their first-order beliefs in response to evidence suggesting that the reasoning underlying those beliefs is faulty—is sometimes thought to be in tension with Bayesian approaches to belief update: in order to obey Bayesian norms, it’s claimed, agents must remain steadfast in the face of higher-order evidence. But I argue that this claim is incorrect. In particular, (...) I motivate a minimal constraint on a reasonable treatment of the evolution of self-locating beliefs over time and show that calibrationism is compatible with any generalized Bayesian approach that respects this constraint. I then use this result to argue that remaining steadfast isn’t the response to higher-order evidence that maximizes expected accuracy. (shrink)

Recent authors have drawn attention to a new kind of defeating evidence commonly referred to as higher-order evidence. Such evidence works by inducing doubts that one’s doxastic state is the result of a flawed process – for instance, a process brought about by a reason-distorting drug. I argue that accommodating defeat by higher-order evidence requires a two-tiered theory of justification, and that the phenomenon gives rise to a puzzle. The puzzle is that (...) at least in some situations involving higher-order defeaters the correct epistemic rules issue conflicting recommendations. For instance, a subject ought to believe p, but she ought also to suspend judgment in p. I discuss three responses. The first resists the puzzle by arguing that there is only one correct epistemic rule, an Über-rule. The second accepts that there are genuine epistemic dilemmas. The third appeals to a hierarchy or ordering of correct epistemic rules. I spell out problems for all of these responses. I conclude that the right lesson to draw from the puzzle is that a state can be epistemically rational or justified even if one has what looks to be strong evidence to think that it is not. As such, the considerations put forth constitute a non question-begging argument for a kind of externalism. (shrink)

In the contemporary epistemological literature, peer disagreement is often taken to be an instance of a more general phenomenon of “higher-order evidence.” Correspondingly, its epistemic significance is often thought to turn on the epistemic significance of higher-order evidence in general. This chapter attempts to evaluate this claim, and in doing so to clarify some points of unclarity in the current literature – both about what it is for evidence to be “higher-order,” (...) and about the relationship between disagreement and higher-order evidence. We will begin by considering some candidate definitions of “higher-order evidence,” and offering our own definition that attempts to capture the phenomenon of interest. We will then consider, in light of this definition, whether disagreement and its epistemic significance are best-understood as a kind of higher-order evidence. We’ll argue that although peer disagreement can be epistemically significant qua higher-order evidence, this role doesn’t exhaust its significance, and that it can also serve as straightforward first-order evidence. Finally, we’ll suggest that inattention to this latter point has made broadly conciliatory views about peer disagreement seem somewhat easier to resist than they in fact are. (shrink)

On at least one of its uses, ‘higher-order evidence’ refers to evidence about what opinions are rationalized by your evidence. This chapter surveys the foundational epistemological questions raised by such evidence, the methods that have proven useful for answering them, and the potential consequences and applications of such answers.

A critical survey of recent work in epistemology on higher-order evidence. It discusses the nature of higher-order evidence, some puzzles it raises, responses to those puzzles, and problems facing them. It concludes by indicating connections between debates concerning higher-order evidence in epistemology and parallel debates in ethics and aesthetics.

This chapter examines the ways in which the debates about the epistemic significance of disagreement are debates about the nature and impact of higher-order evidence.

The paper proposes an account of the rational response to higher-order evidence whose key claim is that whenever we acquire such evidence we ought to engage in the inquiring activity of double-checking. Combined with a principle that establishes a connection between rational inquiry and rational belief retention, the account offers a novel explanation of the alleged impermissibility of retaining one’s belief in the face of higher-order evidence. It is argued that this explanation is (...) superior to the main competitor view which appeals to the notion of defeat. (shrink)

There has been considerable puzzlement over how to respond to higher-order evidence. The existing dilemmas can be defused by adopting a ‘two-dimensional’ representation of doxastic attitudes which incorporates not only substantive uncertainty about which first-order state of affairs obtains but also the degree of conviction with which we hold the attitude. This makes it possible that in cases of higher-order evidence the evidence sometimes impacts primarily on our conviction, rather than our substantive (...) uncertainty. I argue that such a two-dimensional representation is naturally developed by making use of imprecise probabilities. (shrink)

Evidentialism is the thesis that a person is justified in believing a proposition iff the person's evidence on balance supports that proposition. In discussing epistemological issues associated with disagreements among epistemic peers, some philosophers have endorsed principles that seem to run contrary to evidentialism, specifying how one should revise one's beliefs in light of disagreement. In this paper, I examine the connection between evidentialism and these principles. I argue that the puzzles about disagreement provide no reason to abandon evidentialism (...) and that there are no true general principles about justified responses to disagreement other than the general evidentialist principle. I then argue that the puzzles about disagreement are primarily puzzles about the evidential impact of higher - order evidence – evidence about the significance or existence of ordinary, or first- order, evidence. I conclude by arguing that such higher - order evidence can often have a profound effect on the justification of first- order beliefs. (shrink)

Sometimes we get evidence of our own epistemic malfunction. This can come from finding out we’re fatigued, or have been drugged, or that other competent and well-informed thinkers disagree with our beliefs. This sort of evidence seems to seems to behave differently from ordinary evidence about the world. In particular, getting such evidence can put agents in a position where the most rational response involves violating some epistemic ideal.

Thinking about misleading higher-order evidence naturally leads to a puzzle about epistemic rationality: If one’s total evidence can be radically misleading regarding itself, then two widely-accepted requirements of rationality come into conflict, suggesting that there are rational dilemmas. This paper focuses on an often misunderstood and underexplored response to this (and similar) puzzles, the so-called conflicting-ideals view. Drawing on work from defeasible logic, I propose understanding this view as a move away from the default metaepistemological position (...) according to which rationality requirements are strict and governed by a strong, but never explicitly stated logic, toward the more unconventional view, according to which requirements are defeasible and governed by a comparatively weak logic. When understood this way, the response is not committed to dilemmas. (shrink)

Many theories of rational belief give a special place to logic. They say that an ideally rational agent would never be uncertain about logical facts. In short: they say that ideal rationality requires "logical omniscience." Here I argue against the view that ideal rationality requires logical omniscience on the grounds that the requirement of logical omniscience can come into conflict with the requirement to proportion one’s beliefs to the evidence. I proceed in two steps. First, I rehearse an influential (...) line of argument from the "higher-order evidence" debate, which purports to show that it would be dogmatic, even for a cognitively infallible agent, to refuse to revise her beliefs about logical matters in response to evidence indicating that those beliefs are irrational. Second, I defend this "anti-dogmatism" argument against two responses put forth by Declan Smithies and David Christensen. Against Smithies’ response, I argue that it leads to irrational self-ascriptions of epistemic luck, and that it obscures the distinction between propositional and doxastic justification. Against Christensen’s response, I argue that it clashes with one of two attractive deontic principles, and that it is extensionally inadequate. Taken together, these criticisms will suggest that the connection between logic and rationality cannot be what it is standardly taken to be—ideal rationality does not require logical omniscience.

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.

First-order evidence is evidence which bears on whether a proposition is true. Higher-order evidence is evidence which bears on whether a person is able to assess her evidence for or against a proposition. A widespread view is that higher-order evidence makes a difference to whether it is rational for a person to believe a proposition. In this paper, I consider in what way higher-order evidence might do (...) this. More specifically, I consider whether and how higher-order evidence plays a role in determining what it is rational to believe distinct from that which first-order evidence plays. To do this, I turn to the theory of reasons, and try to situate higher-order evidence within it. The only place I find for it there, distinct from that which first-order evidence already occupies, is as a practical reason, that is, as a reason for desire or action. One might take this to show either that the theory of reasons is inadequate as it stands or that higher-order evidence makes no distinctive difference to what it is rational to believe. I tentatively endorse the second option. (shrink)

This book offers a systematic look at current challenges in moral epistemology through the lens of research on higher-order evidence. Fueled by recent advances in empirical research, higher-order evidence has generated a wealth of insights about the genealogy of moral beliefs. Higher-Order Evidence and Moral Epistemology explores how these insights have an impact on the epistemic status of moral beliefs. The essays are divided into four thematic sections. Part I addresses the (...) normative significance of higher-order evidence for moral epistemology. Part II covers the sources of higher-order evidence in moral epistemology, such as disagreement and moral testimony, for both individuals and groups. The essays in Part III discuss permissible epistemic attitudes regarding a body of moral evidence, including the question of how to determine the permissibility of such attitudes. Finally, Part IV examines the relevance of higher-order evidence for phenomena of practical concern, such as fundamentalist views about moral matters. This volume is the first to explicitly address the implications of higher-order evidence in moral epistemology. It will be of interest to researchers and advanced graduate students working in epistemology and metaethics. (shrink)

In deep disagreements local disagreements are intertwined with more general basic disagreements about the relevant evidence, standards of argument or proper methods of inquiry in that domain. The paper provides a more specific conception of deep disagreement along these lines and argues that while we should generally conciliate in cases of disagreement, this is not so in deep disagreements. The paper offers a general view of disagreement, holding roughly that one should moderate one’s credence towards uncertainty in so far (...) as disagreement with others provides undefeated higher order evidence that one might have made a mistake in one’s appreciation of the first order evidence. When applying this view to deep disagreement we get that in cases of deep disagreement higher order evidence from disagreement is rebutted or undercut by the nature of the disagreement. So, in cases of deep disagreement one should not moderate one’s credence. I finally argue that this gives a better general view of deep disagreement than views appealing to epistemic peers, personal information or independence. (shrink)

Suppose we learn that we have a poor track record in forming beliefs rationally, or that a brilliant colleague thinks that we believe P irrationally. Does such input require us to revise those beliefs whose rationality is in question? When we gain information suggesting that our beliefs are irrational, we are in one of two general cases. In the first case we made no error, and our beliefs are rational. In that case the input to the contrary is misleading. In (...) the second case we indeed believe irrationally, and our original evidence already requires us to fix our mistake. In that case the input to that effect is normatively superfluous. Thus, we know that information suggesting that our beliefs are irrational is either misleading or superfluous. This, I submit, renders the input incapable of justifying belief revision, despite our not knowing which of the two kinds it is. (shrink)

We often have reason to doubt our own ability to form rational beliefs, or to doubt that some particular belief of ours is rational. Perhaps we learn that a trusted friend disagrees with us about what our shared evidence supports. Or perhaps we learn that our beliefs have been afflicted by motivated reasoning or other cognitive biases. These are examples of higher-order evidence. While it may seem plausible that higher-order evidence should impact our (...) beliefs, it is less clear how and why. Normally, when evidence impacts our beliefs, it does so by virtue of speaking for or against the truth of theirs contents. But higher-order evidence does not directly concern the contents of the beliefs that they impact. In recent years, philosophers have become increasingly aware of the need to understand the nature and normative role of higher-order evidence. This is partly due to the pervasiveness of higher-order evidence in human life. But it has also become clear that higher-order evidence plays a central role in many epistemological debates, spanning from traditional discussions of internalism/externalism about epistemic justification to more recent discussions of peer disagreement and epistemic akrasia. This volume brings together, for the first time, a distinguished group of leading and up-and-coming epistemologists to explore a range of issues about higher-order evidence. (shrink)

In this introduction, I explain the notion of higher-order evidence and explore its bearing on aesthetic judgement. I start by illustrating how reflection on cases involving higher-order evidence engages with well-established concerns in aesthetics—specifically, how it might reveal tensions within and between widely recognized aesthetic ideals governing aesthetic judgement. Next, I show how attention to higher-order evidence in relation to aesthetic judgement might expose limitations or assumptions of theories in epistemology, where (...) the nature and significance of higher-order evidence with respect to belief is the focus of much recent attention. The aim is not to resolve the issues but to demonstrate the significance of higher-order evidence in aesthetics and, in doing so, encourage work on the topic in and across aesthetics and epistemology.

Evidentialism as an account of theoretical rationality is a popular and well-defended position. However, recently, it's been argued that misleading higher-order evidence (HOE) – that is, evidence about one's evidence or about one's cognitive functioning – poses a problem for evidentialism. Roughly, the problem is that, in certain cases of misleading HOE, it appears evidentialism entails that it is rational to adopt a belief in an akratic conjunction – a proposition of the form “p, but (...) my evidence doesn't support p” – despite it being the case that believing an akratic conjunction appears to be clearly irrational. In this paper, I diffuse the problem for evidentialism using the distinction between propositional and doxastic rationality. I argue that, although it can be propositionally rational to believe an akratic conjunction (according to evidentialism), one cannot inferentially base an akratic belief in one's evidence, and, thus, one cannot doxastically rationally possess an akratic belief. In addition, I address the worry that my solution to the puzzle commits evidentialists to the possibility of epistemic circumstances in which a proposition, p, is propositionally rational to believe (namely, an akratic conjunction), yet one cannot, in principle, (doxastically) rationally believe p. As I demonstrate, cases of misleading HOE are not the only types of cases that force evidentialists to accept that propositional rationality does not entail the possibility of doxastic rationality. There are no new problems raised by misleading HOE that weren't already present in cases involving purely first-order evidence. (shrink)

My aim in this paper is to develop and defend a novel answer to a question that has recently generated a considerable amount of controversy. The question concerns the normative significance of peer disagreement. Suppose that you and I have been exposed to the same evidence and arguments that bear on some proposition: there is no relevant consideration which is available to you but not to me, or vice versa. For the sake of concreteness, we might picture.

Higher-order evidence is, roughly, evidence of evidence. The idea is that evidence comes in levels. At the first, or lowest, evidential level is evidence of the familiar type—evidence concerning some proposition that is not itself about evidence. At a higher evidential level the evidence concerns some proposition about the evidence at a lower level. Only in relatively recent years has this less familiar type of evidence been explicitly (...) identified as a subject of epistemological focus, and the work on it remains relegated to a small circle of authors and a short stack of published articles—far disproportionate to the attention it deserves. It deserves to occupy center stage for several reasons. First, higher-order evidence frequently arises in a strikingly diverse range of epistemic contexts, including testimony, disagreement, empirical observation, introspection, and memory, among others. Second, in many of the contexts in which it arises, such evidence plays a crucial epistemic role. Third, the precise role it plays is complex, gives rise to a number of interesting epistemological puzzles, and for these reasons remains controversial and is not yet fully understood. As such, higher-order evidence merits systematic investigation. This thesis undertakes such an investigation. It aims to produce a thorough account of higher-order evidence—what it is, how it works, and its epistemic consequences. Chapter 1 serves as a general introduction to the topic and an overview of the existing literature, but primarily aims to further elucidate the concept of higher-order evidence and build a theoretical framework for later chapters. Chapter 2 develops an account of what I call “higher-order support”: the bearing higher-order evidence has, not on corresponding “lower-order evidence” (roughly, the evidence the higher-order evidence is about), but on corresponding “object-level propositions” (roughly, the propositions the higher-order evidence alleges the lower-order evidence to be about). Chapter 3 develops an account of “levels interaction”: the effect on overall support when the different evidential levels combine. Chapter 4 identifies important consequences of the theoretical results of the previous two chapters and applies the theory to four select cases of current epistemological controversy—testimony, memory, the closure of inquiry, and disagreement.

This chapter provides a critical overview of several influential proposals about the epistemic function of higher-order evidence. I start by criticizing accounts of higher-order evidence that appeal to evidential defeat (§1), epistemic conflicts (§2), and unreasonable knowledge (§3). Next, I propose an alternative account that appeals to a combination of improper basing (§4) and non-ideal rationality (§5). Finally, I conclude by summarizing my reasons for preferring this account of higher-order evidence to (...) the alternatives (§6). (shrink)

In everyday life and in science we acquire evidence of evidence and based on this new evidence we often change our epistemic states. An assumption underlying such practice is that the following EEE Slogan is correct: 'evidence of evidence is evidence' (Feldman 2007, p. 208). We suggest that evidence of evidence is best understood as higher-order evidence about the epistemic state of agents. In order to model evidence (...) of evidence we introduce a new powerful framework for modelling epistemic states, Dyadic Bayesianism. Based on this framework, we then discuss characterizations of evidence of evidence and argue for one of them. Finally, we show that whether the EEE Slogan holds, depends on the specific kind of evidence of evidence. (shrink)

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

This paper sketches a general account of how to respond in an epistemically rational way to moral disagreement. Roughly, the account states that when two parties, A and B, disagree as to whether p, A says p while B says not-p, this is higher-order evidence that A has made a cognitive error on the first-order level of reasoning in coming to believe that p. If such higher-order evidence is not defeated, then one rationally (...) ought to reduce one’s confidence with respect to the proposition in question. We term this the higher-order evidence account, and present it as a superior to what we might call standard conciliationism, which holds that when agents A and B disagree about p, and are epistemic peers, they should both suspend judgement about p or adjust their confidence towards the mean of A and B’s prior credences in p. Many have suspected that standard conciliationism is implausible and may have skeptical implications. After presenting the HOE account, we put it to work by applying it to a range of cases of moral disagreement, including those that have feature in recent debates assuming standard conciliationism. We show that the HOE account support reasonable, non-skeptical verdicts in a range of cases. Note that this is a paper on moral disagreement, not on the HOE account, thus the account is merely stated here, while defended more fully elsewhere. (shrink)

Most epistemologists maintain that we are rationally required to believe what our evidence supports. Generally speaking, any factor that makes it more probable that a given state of affairs obtains (or does not obtain) is evidence (for that state of affairs). In line with this view, many metaethicists believe that we are rationally required to believe what’s morally right and wrong based on what our moral evidence (e.g. our moral intuitions, along with descriptive information about the world) (...) supports. However, sometimes we get information about our evidence, such as a theory that explains that all moral intuitions are ultimately caused by evolutionary forces. Such genealogical claims like this take form as a puzzle about how to rationally respond to higher-order evidence in moral epistemology. How should we change our moral views in response to genealogical claims about the evolutionary origin of our moral beliefs or about widespread moral disagreement? This introductory chapter first explains the issue about how to change our moral views based on an easily accessible example. Then it shows how recent debates about the puzzle of higher-order evidence bears on recent debates in moral epistemology, notably the debates about evolutionary debunking arguments in metaethics, the epistemic significance of moral peer disagreement, moral testimony, and collective moral knowledge before it introduces the chapters of this book.

Suppose that Sherlock Holmes has just closed another case, and is convinced that Moriarty is the perpetrator. At that very moment, Inspector Lestrade arrives to inform Holmes that a Scotland Yard analysis of his past investigations shows that he only identifies the correct suspect in 50% of cases. How should Holmes respond to this new information? This is a question about higher-order evidence. Higher-order evidence can be understood as evidence about the rationality of (...) your beliefs, or about your reliability in judging matters in a certain domain. Some views on higher-order evidence, like calibrationism, say that Holmes should drastically reduce his confidence that Moriarty is the perpetrator, in light of what he learns about his track record. Other perspectives will recommend that Holmes stick to his guns instead. This dissertation explores the nature and epistemic significance of higher-order evidence, and considers whether higher-order evidence we acquire from empirical research into human evolution might serve to undermine the justification for our moral beliefs, as evolutionary debunking arguments, like those advanced by Sharon Street and Richard Joyce, have alleged. Ultimately, I argue that the calibrationist response to higher-order evidence is the right one, and that our emerging understanding of how morality evolved does indeed pose a serious challenge to the epistemic status of our moral beliefs.

Are the circumstances in which moral testimony serves as evidence that our judgement-forming processes are unreliable the same circumstances in which mundane testimony serves as evidence that our mundane judgement-forming processes are unreliable? In answering this question, we distinguish two possible roles for testimony: (i) providing a legitimate basis for a judgement, (ii) providing (‘higher-order’) evidence that a judgement-forming process is unreliable. We explore the possibilities for a view according to which moral testimony does not, (...) in contrast to mundane testimony play role (i), but can play role (ii). We argue that standard motivations for rejecting this hybrid position are unpersuasive but suggest that a more compelling reason might be found in considering the social nature of morality. (shrink)

Higher-order evidence is evidence about what is rational to think in light of your evidence. Many have argued that it is special – falling into its own evidential category, or leading to deviations from standard rational norms. But it is not. Given standard assumptions, almost all evidence is higher-order evidence.

Scientific disagreements are an important catalyst for scientific progress. But what happens when scientists disagree amidst times of crisis, when we need quick yet reliable policy guidance?

Starting from an argumentative, pragma-dialectic account of scientific controversies, we argue for the importance of ‘higher-order evidence’ (HOE) and we specify desiderata (...) for scientifically relevant HOE.

The Self-Intimation thesis has it that whatever justificatory status a proposition has, i.e., whether or not we are justified in believing it, we are justified in believing that it has that status. The Infallibility thesis has it that whatever justificatory status we are justified in believing that a proposition has, the proposition in fact has that status. Jointly, Self-Intimation and Infallibility imply that the justificatory status of a proposition closely aligns with the justification we have about that justificatory status. Self-Intimation (...) has two noteworthy implications. First, assuming that we never have sufficient justification for a proposition and for its negation, we can derive Infallibility from Self-Intimation. Interestingly, there seems to be no equivalently simple way to derive Self-Intimation from Infallibility. This asymmetry provides reason for thinking that bottom-level justification rather than top-level justification drives the explanation for why the levels of justification align. Second, Self-Intimation suggests a counterintuitive treatment of information concerning what justificatory status a proposition has. It follows from Self-Intimation that we always have justification for the truth about whether a proposition is justified for us, and therefore, that higher-order evidence could change what we should believe on this matter only by misleading us. This permits forming beliefs about whether a proposition is justified for us without regard to higher-order evidence, and thus reveals a reason for thinking that top-level justification is evidentially inert.

We demonstrate that many philosophers accept the following claim: When an aesthetic object is apprehended correctly, taking pleasure in said object is a reliable sign that the object is aesthetically successful. We undermine this position by showing that what grounds our pleasurable experience is opaque: In many cases, the experienced pleasure is attributable to factors that have little to do with the aesthetic object. The evidence appealed to is a form of Higher-Order Evidence (HOE) and we (...) consider attempts to overcome said evidence. We argue they are unsuccessful. We conclude by considering what this means for our practice of making aesthetic judgements. (shrink)

Evidentialism is the thesis, roughly, that one’s beliefs should fit one’s evidence. The enkratic principle is the thesis, roughly, that one’s beliefs should "line up" with one’s beliefs about which beliefs one ought to have. While both theses have seemed attractive to many, they jointly entail the controversial thesis that self-misleading evidence is impossible. That is to say, if evidentialism and the enkratic principle are both true, one’s evidence cannot support certain false beliefs about which beliefs one’s (...) evidence supports. Recently, a number of epistemologists have challenged the thesis that self-misleading evidence is impossible on the grounds that misleading higher-order evidence does not have the kind of strong and systematic defeating force that would be needed to rule out the possibility of such self-misleading evidence. Here I respond to this challenge by proposing an account of higher-order defeat that does, indeed, render self-misleading evidence impossible. Central to the proposal is the idea that higher-order evidence acquires its normative force by influencing which conditional beliefs it is rational to have. What emerges, I argue, is an independently plausible view of higher-order evidence, which has the additional benefit of allowing us to reconcile evidentialism with the enkratic principle. (shrink)

Conciliatory views of disagreement maintain that discovering a particular type of disagreement requires that one make doxastic conciliation. In this paper I give a more formal characterization of such a view. After explaining and motivating this view as the correct view regarding the epistemic significance of disagreement, I proceed to defend it from several objections concerning higher-order evidence (evidence about the character of one's evidence) made by Thomas Kelly (2005).

This paper proposes a novel answer to the question of what attitude agents should adopt when they receive misleading higher-order evidence that avoids the drawbacks of existing views. The answer builds on the independently motivated observation that there is a difference between attitudes that agents form as conclusions of their reasoning, called terminal attitudes, and attitudes that are formed in a transitional manner in the process of reasoning, called transitional attitudes. Terminal and transitional attitudes differ both in (...) their descriptive and in their normative properties. When an agent receives higher-order evidence that they might have reasoned incorrectly to a belief or credence towards p, then their attitude towards p is no longer justified as a terminal attitude towards p, but it can still be justified as a transitional attitude. This view, which I call the unmooring view, allows us to capture the rational impact of misleading higher-order evidence in a way that integrates smoothly with a natural picture of epistemic justification and the dynamics of deliberation.

Certain plausible evidential requirements and coherence requirements on rationality seem to yield dilemmas of rationality (in a specific, objectionable sense) when put together with the possibility of misleading higher-order evidence. Epistemologists have often taken such dilemmas to be evidence that we’re working with some false principle. In what follows I show how one can jointly endorse an evidential requirement, a coherence requirement, and the possibility of misleading higher-order evidence without running afoul of dilemmas (...) of rationality. The trick lies in observing the difference between attitudes it is rational to hold (= propositional justification) and rationally holding those attitudes (= doxastic justification). (shrink)

The aim of this paper is to apply the accuracy based approach to epistemology to the case of higher order evidence: evidence that bears on the rationality of one's beliefs. I proceed in two stages. First, I show that the accuracy based framework that is standardly used to motivate rational requirements supports steadfastness—a position according to which higher order evidence should have no impact on one's doxastic attitudes towards first order propositions. The (...) argument for this will require a generalization of an important result by Greaves and Wallace for the claim that conditionalization maximizes expected accuracy. The generalization I provide will, among other things, allow us to apply the result to cases of self-locating evidence. In the second stage, I develop an alternative framework. Very roughly, what distinguishes the traditional approach from the alternative one is that, on the traditional picture, we're interested in evaluating the expected accuracy of conforming to an update procedure. On the alternative picture that I develop, instead of considering how good an update procedure is as a plan to conform to, we consider how good it is as a plan to make. I show how, given the use of strictly proper scoring rules, the alternative picture vindicates calibrationism: a view according to which higher order evidence should have a significant impact on our beliefs. I conclude with some thoughts about why higher order evidence poses a serious challenge for standard ways of thinking about rationality. (shrink)

Abstract. This paper argues that the “Argument from Moral Peer Disagreement” fails to make a case for widespread moral skepticism. The main reason for this is that the argument rests on a too strong assumption about the normative significance of peer disagreement (and higher-order evidence more generally). In order to demonstrate this, I distinguish two competing ways in which one might explain higher-order defeat. According to what I call the “Objective Defeat Explanation” it is (...) the mere possession of higher-order evidence that explains defeat. I argue that this type of explanation is problematic and that it at best collapses into another explanation I call the “Subjective Defeat Explanation”. According to this explanation, it is coming to believe that one’s belief fails to be rational that explains defeat. Then I go on to argue that the Subjective Defeat Explanation is able to provide a straightforward explanation of higher-order defeat but that it entails that peer disagreement (and higher-order evidence more generally) only contingently gives rise to defeat, and importantly, that the condition it is contingent upon is very often not satisfied when it comes to moral peer disagreement specifically. As a result, it appears that moral knowledge is seldom threatened by moral peer disagreement. (shrink)
