Our main question in this paper is as follow: (Q) What are the epistemic norms governing our responses in the face of disagreement? In order to answer it, we begin with some clarification. First, following McHugh (2012), if we employ a useful distinction in normativity theory between evaluative and prescriptive norms, there are two readings of (Q)––we explore such distinction in section 2. And secondly, we accept gnosticism, that is, the account that the fundamental epistemic good is knowledge. It is (...) with this assumption that we want to answer (Q). So, if gnosticism is true, what is the plausible answer to (Q)? In section 3 we argue for gnostic disagreement norms as response to (Q) and in section 4 we apply such norms to particular cases of disagreement. (shrink)

Is logic normative for belief? A standard approach to answering this question has been to investigate bridge principles relating claims of logical consequence to norms for belief. Although the question is naturally an epistemic one, bridge principles have typically been investigated in isolation from epistemic debates over the correct norms for belief. In this paper we tackle the question of whether logic is normative for belief by proposing a Kripkean model theory accounting for the interaction between logical, doxastic, epistemic and (...) deontic notions and using this model theory to show which bridge principles are implied by epistemic norms that we have independent reason to accept, for example, theknowledge normand thetruth norm. We propose a preliminary theory of the interaction between logical, doxastic, epistemic and deontic notions that has among its commitments bridge principles expressing how logic is normative for belief. We also show how our framework suggests that logic is exceptionally normative. (shrink)

This is an opinionated guide to the literature on epistemic dilemmas. It discusses seven kinds of situations where epistemic dilemmas appear to arise; dilemmic, dilemmish, and non-dilemmic takes on them; and objections to dilemmic views along with dilemmist’s replies to them.

This is a defence of externalism about knowledge and also about justification. In this paper, I argue that an important virtue of externalism about these notions is that externalism about justification helps to explain the value of (i.e., importance of) knowledge. I also develop and expand upon some of my earlier arguments for externalism that drew upon what's now known as 'morally loaded cases'. The virtue of externalism is that it's the only view that can both allow for certain kinds (...) of categorical normative requirements while also vindicating the idea that we ought to be guided by the beliefs that we ought to have. (Internalists either have to deny that we ought to be guided by the beliefs that we ought to have (which isn't very internalist!) or, failing that, revise our views about the existence of certain kinds of categorical requirements and tell us that we ought to be guided by our beliefs to do evil things (which isn't very nice!).).

Incoherence is usually regarded as a bad thing. Incoherence suggests irrationality, confusion, paradox. Incoherentism disagrees: incoherence is not always a bad thing, sometimes we ought to be incoherent. If correct, Incoherentism has important and controversial implications. It implies that rationality does not always require coherence. Dilemmism and Incoherentism both embrace conflict in epistemology. After identifying some important differences between these two ways of embracing conflict, I offer some reasons to prefer Incoherentism over Dilemmism. Namely, that Incoherentism allows us to deliberate (...) about what we ought to believe using ordinary epistemology, and it does a better job of accommodating the positive features of incoherence.

Daniel Greco (forthcoming) argues that there cannot be epistemic dilemmas. I argue that he is wrong. I then look in detail at a would-be epistemic dilemma and argue that no non-dilemmic approach to it can be made to work. Along the way, there is discussion of octopuses, lobsters, and other ‘inscrutable cognizers’; the relationship between evaluative and prescriptive norms; a failed attempt to steal a Brueghel; epistemic and moral blame and residue; an unbearable guy who thinks he’s God’s gift to (...) women; excuses; stupid games involving hats; radical permissivism; how I’ll never be able to afford to buy a house in Hampstead; and many other exciting topics.

I argue that evidentialism should be rejected because it cannot be reconciled with empirical work on bias in cognitive and social psychology.

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.

It is widely held that our beliefs can be epistemically faultless despite being morally flawed. Theories of moral encroachment challenge this, holding that moral considerations bear on the epistemic status of our attitudes. According to attitude-based theories of moral encroachment, morality encroaches upon the epistemic standing of our attitudes on the grounds that we can morally injure others with our epistemic practices. In this paper, I aim to show that current attitude-based theories have asymmetric mechanisms: moral features only make it (...) harder for attitudes to secure epistemic merits. I argue that, if attitudes can incur moral injury, failure to form attitudes can too. To make sense of this, I contend, attitude-based accounts require symmetric mechanisms, allowing that moral considerations make it both harder and easier for attitudes to attain epistemic merits. I maintain that, once we recognize this, attitude-based encroachment views must soon concede that they sometimes demand we believe against the evidence. (shrink)

If it is ethically wrong to hold some beliefs, there may be a conflict between the demands of morality and the demands of rationality. A recent theory holds that no such conflict exists: any morally wrong belief is also irrational to hold, made irrational through a phenomenon of radical moral encroachment. In this paper, I argue that radical moral encroachment fails to coordinate ethical and epistemic norms, given plausible epistemological principles and various substantive accounts of which beliefs are morally wrong, (...) including those endorsed by radical moral encroachment theorists themselves. (shrink)

Should you always be certain about what you should believe? In other words, does rationality demand higher-order certainty? First answer: Yes! Higher-order uncertainty can’t be rational, since it breeds at least a mild form of epistemic akrasia. Second answer: No! Higher-order certainty can’t be rational, since it licenses a dogmatic kind of insensitivity to higher-order evidence. Which answer wins out? The first, I argue. Once we get clearer about what higher-order certainty is, a view emerges on which higher-order certainty does (...) not, in fact, license any kind of insensitivity to higher-order evidence. The view as I will describe it has plenty of intuitive appeal. But it is not without substantive commitments: it implies a strong form of internalism about epistemic rationality, and forces us to reconsider standard ways of thinking about the nature of evidential support. Yet, the view put forth promises a simple and elegant solution to a surprisingly difficult problem in our understanding of rational belief. (shrink)

I argue that if there are nondisabled reasons to believe p, then there cannot be nondisabled reasons to believe something incompatible with p. I first defend a restricted version of the view, which applies only to situations where the relevant agent has complete evidence. Then, I argue for a generalized version of the view, which holds regardless of the agent's evidence. As a related result, I show that, given plausible assumptions, there cannot be nondisabled reasons to believe something false.

Conceptual limitations restrict our epistemic options. One cannot believe, disbelieve, or doubt what one cannot grasp. I show how, even granting an epistemic ought-implies-can principle, such restrictions might lead to epistemic dilemmas: situations where each of one’s options violates some epistemic requirement. An alternative reaction would be to take epistemic norms to be sensitive to one’s options in ways that ensure dilemmas never arise. I propose, on behalf of the dilemmist, that we treat puzzlement as a kind of epistemic residue, (...) roughly analogous with guilt, appropriate only when one has violated an epistemic requirement. Sometimes, in bumping up against the limits of one’s concepts, it is appropriate to be puzzled no matter what one believes. Puzzlement can thus play the same role in an epistemic dilemmist’s theory that guilt plays in the theories of many moral dilemmists. (shrink)

Conciliationism is the view that an agent must revise her belief in a proposition when she becomes aware that there is an epistemic peer who disagrees with her about that proposition. If epistemic peers are anything less than strict cognitive and evidential equals, then even slight differences could explain away why the two parties disagree in the first place. But this strict notion of peerhood never obtains in many, if not most, of real-life cases disagreements between inquirers. One recent account (...) of peerhood which might obtain more frequently in cases of real-life disagreements comes from Elgin Voicing dissent: the ethics and epistemology of making disagreement public, Routledge, New York, pp 10–21, 2018). She argues that two scientists who are epistemic peers can disagree because while they might have the same reasoning abilities, they can have different reasoning styles. While there are merits to Elgin’s account, I argue that two people with different reasoning styles are unlikely to be epistemic peers since such differences could serve to explain away why they disagree. I argue that there is a conception of peerhood which can retain the sceptical force of conciliationism without trivializing or dismissing the problem of disagreement. I then conclude that a particularly attractive argument against conciliationism is gestured at by Elgin in one of her earlier pieces on disagreement. This argument is based on the idea that there are epistemic benefits to be gained from remaining steadfast in the face of disagreement Disagreement, Oxford University Press, Oxford, pp 53–68, 2010). The success of this argument, however, might force an inquirer faced with disagreement to choose between synchronic reasons and diachronic reasons. If Hughes’ recent defense of epistemic dilemmism is correct this may be a feature of the argument, rather than a bug. (shrink)

This paper is about epistemic dilemmas, i.e., cases in which one is doomed to have a doxastic attitude that is rationally impermissible no matter what. My aim is to develop and defend a position according to which there can be genuine rational indeterminacy; that is, it can be indeterminate which principles of rationality one should satisfy and thus indeterminate which doxastic attitudes one is permitted or required to have. I am going to argue that this view can resolve epistemic dilemmas (...) in a systematic way while also enjoying some important advantages over its rivals. (shrink)

This paper is about an anti-expertise paradox that arises because of self-referential sentences like: = I do not believe that is true. The first aim is to motivate, develop, and defend a novel view of epistemic rationality according to which there can be genuine rational indeterminacy, i.e., it can be indeterminate which doxastic states an agent is rationally permitted or required to have. The second aim is to show how this view can provide a solution to this paradox while also (...) avoiding the problems that plague its rivals. (shrink)

Epistemologists often appeal to the idea that a normative theory must provide useful, usable, guidance to argue for one normative epistemology over another. I argue that this is a mistake. Guidance considerations have no role to play in theory choice in epistemology. I show how this has implications for debates about the possibility and scope of epistemic dilemmas, the legitimacy of idealisation in Bayesian epistemology, uniqueness versus permissivism, sharp versus mushy credences, and internalism versus externalism.

Epistemologists spend a great deal of time thinking about how we should respond to our evidence. They spend far less time thinking about the ways that evidence can be acquired in the first place. This is an oversight. Some ways of acquiring evidence are better than others. Many normative epistemologies struggle to accommodate this fact. In this article I develop one that can and does. I identify a phenomenon – epistemic feedback loops – in which evidence acquisition has gone awry, (...) with the result that even beliefs based on the evidence are irrational. Examples include evidence acquired under the influence of confirmation bias and evidence acquired under the influence of cognitively penetrated experiences caused by implicit bias. I then develop a theoretical framework which enables us to understand why beliefs that are the outputs of epistemic feedback loops are irrational. Finally, I argue that many popular approaches to epistemic normativity may need to be abandoned on the grounds that they cannot comfortably explain feedback loops. The scope of this last claim is broad: it includes almost all contemporary theories of justified/rational belief and of the epistemology of cognitive penetration. (shrink)

According to moral encroachment facts about epistemic justification can vary with moral factors that are unrelated to the truth of the belief. Most of the literature on this topic has focused on how beliefs can wrong, and whether the data that moral encroachers offer in support of their view can be explained within a purist framework. A largely neglected question has been what kind of consequences moral encroachment would have for epistemic justification if the thesis were true. Here I remedy (...) this shortcoming by examining what kind of structural implications moral encroachment has for epistemic justification. (shrink)

According to a popular account, rationality is a kind of coherence of an agent’s mental states and, more specifically, a matter of fulfilling norms of coherence. For example, in order to be rational, an agent is required to intend to do what they judge they ought to and can do. This norm has been called ‘Enkrasia’. Another norm requires that, ceteris paribus, an agent retain their intention over time. This has been called ‘Persistence of Intention’. This paper argues that thus (...) understood norms of rationality may at times conflict. More specifically, Enkrasia and Persistence of Intention may place demands on the agent that are impossible to fulfil. In these cases, the framework of requirements does not provide us with norms that make us rational. A rival account, according to which rationality is a kind of responsiveness to one’s available reasons, can overcome the problem. (shrink)

This article provides an overview of recent work on norms of inquiry. After some preliminaries about inquiry in §1, I discuss in §2 the ignorance norm for inquiry, presenting arguments for and against, as well as some alternatives. In §3, I consider its relation to the aim of inquiry. In §4, I discuss positive norms on inquiry: norms that require having rather than lacking certain states. Finally, in §5, I look at questions about the place of norms of inquiry within (...) normative epistemology. (shrink)

Benjamin Kiesewetter has recently provided an argument to the effect that necessarily, if one has decisive reason to φ, then one has sufficient reason to believe that she herself has decisive reason to φ. If sound, this argument has important implications for several debates in contemporary normative philosophy. I argue that the main premise in the argument is problematic and should be rejected. According to this premise (PRR), necessarily, one can respond correctly to all the decisive reasons one has. I (...) show that PRR is confronted with counterexamples and presupposes an implausible commensurability of all kinds of reasons. If so, the conclusion in Kiesewetter’s argument doesn’t follow. I also discuss further implications of my objections to PRR for a specific family of ‘ought’ implies ‘can’ principles and ability constraints on reasons, and the consequences that these could have for a number of contemporary debates in normative philosophy.

An increasingly popular view in contemporary epistemology holds that the most fundamental norm governing belief is knowledge. According to this norm one shouldn’t believe what one doesn’t know. A prominent argument for the knowledge norm appeals to the claim that knowledge is the most general condition of epistemic assessment of belief, one entailing all other conditions under which we epistemically assess beliefs. This norm would provide an easy and straightforward explanation of why we assess beliefs along all these various epistemic (...) dimensions. This article argues that this line of argument is ultimately unsuccessful. I show that the main premise of the argument actually supports the opposite conclusion: the norm of belief requires a condition weaker than knowledge. Furthermore, I argue that if we hold on to the assumption that knowledge is the most general condition of belief’s epistemic assessment, the fundamental norm of belief is factive: one is not permitted to believe a proposition p if it is not true that p.

Many epistemologists have argued that there is some degree of independence between individual and collective reliability (e.g., Kitcher 1990; Mayo-Wilson, Zollman, and Danks 2011; Dunn 2018). The question, then, is: To what extent are the two independent of each other? And in which contexts do they come apart? In this paper, I present a new case confirming the independence between individual and collective reliability optimization. I argue that, in voting groups, optimizing individual reliability can conflict with optimizing collective reliability. This (...) can happen even if various conditions are held constant, such as: the evidence jurors have access to, the voting system, the number of jurors, some independence conditions between voters, and so forth. This observation matters in many active debates on, e.g., epistemic dilemmas, the wisdom of crowds, independence theses, epistemic democracy, and the division of epistemic labour. (shrink)

Some epistemologists think that the Bayesian ideals matter because we can approximate them. That is, our attitudes can be more or less close to the ones of our ideal Bayesian counterpart. In this paper, I raise a worry for this justification of epistemic ideals. The worry is this: In order to correctly compare agents to their ideal counterparts, we need to imagine idealized agents who have the same relevant information, knowledge, or evidence. However, there are cases in which one’s ideal (...) counterpart cannot have one’s information, knowledge, or evidence. In these situations, agents cannot compare themselves to their ideal counterpart. (shrink)

A widespread assumption in debates about trust and trustworthiness is that the evaluative norms of principal interest on the trustor’s side of a cooperative exchange regulate trusting attitudes and performances whereas those on the trustee’s side regulate dispositions to respond to trust. The aim here will be to highlight some unnoticed problems with this asymmetrical picture – and in particular, how it elides certain key evaluative norms on both the trustor’s and trustee’s side the satisfaction of which are critical to (...) successful cooperative exchanges – and to show that a symmetrical, ‘achievement-first’ approach to theorising about trust and trustworthiness (and their relation to each other) has important advantages by comparison. The view I develop is guided by a structural analogy with practical reasoning. Just as practical reasoning is working as it should only when there is realisation (knowledge and action) of states (belief and intention) with reverse directions of fits (mind-to-world and world-to-mind), likewise, cooperation between trustor and trustee is functioning as it should only when there is an analogous kind of realisation on both sides of the cooperative exchange – viz., when the trustor ‘matches’ her achievement in trusting (an achievement in fitting reliance to reciprocity) with the trustee’s achievement in responding to trust (an achievement in fitting reciprocity to reliance). An upshot of viewing cooperation between trustor and trustee as exhibiting achievement-theoretic structure is that we will be better positioned to subsume trustworthiness (and its cognates on the trustee’s side), like trust, under a wider suite of evaluative norms that regulate attempts, dispositions, and achievements symmetrically on both sides of a cooperative exchange, with ‘matching achievements’ as the gold standard.

What does logic tells us how about we ought to reason? If P entails Q, and I believe P, should I believe Q? I will argue that we should embed the issue in an independently motivated contextualist semantics for ‘ought’, with parameters for a standard and set of propositions. With the contextualist machinery in hand, we can defend a strong principle expressing how agents ought to reason while accommodating conflicting intuitions. I then show how our judgments about blame and guidance (...) can be handled by this machinery. (shrink)

Rinard (2019) brings to our attention the fact that, typically, the questions What should I believe? and What should I do? are treated differently. A typical answer to the first question is Believe according to the evidence, and a typical answer to the second question is Do what is right. But Rinard rejects this dichotomy. In its place, she argues for a view which she calls “Equal Treatment” in which one should believe according to the same considerations that govern what (...) one should do. Christensen (forthcoming) aptly situates Equal Treatment as a limit case of a recent movement towards taking pragmatic factors as partly determining what one should believe, in that Equal Treatment is a purely pragmatic view. Does Rinard’s case for a purely pragmatic view succeed? This paper argues that the answer is no. Three objections that target key parts of Rinard’s case for Equal Treatment are presented. The upshot is that the dichotomy between the answers to What should I believe? and What should I do? seems robust against strong attempts to dismantle it. (shrink)

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)

I consider a number of reasons one might think we should only accept epistemic dilemmas in our normative epistemology as a last resort and argue that none of them is compelling.

Sometimes we make mistakes, even when we try to do our best. When those mistakes are about normative matters, such as what is required, this leads to a puzzle. This puzzle arises from the possibility of misleading evidence about what rationality requires. I argue that the best way to solve this puzzle is to distinguish between two kinds of evaluation: requirement and appraisal. The strategy I defend connects three distinct debates in epistemology, ethics, and normativity: the debate over how our (...) theories of epistemic rationality should accommodate misleading evidence, the debate over the relationship between complying with requirements and deserving particular appraisals, and the debate over whether normative ignorance can excuse. Part 1 shows how three apparently plausible claims about epistemic rationality generate a puzzle when agents have misleading evidence about what rationality requires. Part 2 solves this puzzle by distinguishing between evaluations of requirement and appraisal and rejecting the idea that one is required to conform to the Enkratic Principle. I argue instead that complying with the Enkratic Principle provides defeasible evidence that the agent should be positively appraised. One of the consequences of this solution is that false normative beliefs can sometimes excuse agents from negative appraisal they would otherwise deserve for violating requirements. Part 3 defends the view that false normative belief can sometimes excuse against the rival views that false normative belief always excuses, and that false normative belief never excuses. I argue that false normative belief can sometimes excuse violations of requirements, when it is the case that the agent has done what it is reasonable to expect of her. (shrink)

According to Humean theories of objective chance, the chances reduce to patterns in the history of occurrent events, such as frequencies. According to non-Humean accounts, the chances are metaphysically fundamental, existing independently of the "Humean Mosaic" of actually-occurring events. It is therefore possible, by the lights of non-Humeanism, for the chances and the frequencies to diverge wildly. Humeans often allege that this undermines the ability of non-Humean accounts of chance to rationalize adherence to David Lewis' Principal Principle (PP), which states (...) that an agent's degrees of belief should match what they take to be the objective chances. In this paper, I propose two approaches to justifying (PP) for non-Humean chance, hence defusing the Humean objection. The first approach justifies (PP) via the role it plays in informing outright beliefs about long-run frequencies. The second approach justifies (PP) by showing that adherence to (PP), even for non-Humean chance, maximizes expected epistemic utility according to the actual objective chance function. I then address an objection to this approach, concerning the alleged circularity of the derivations. (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. (shrink)

This paper concentrates on a particular sort of case where it’s plausible that epistemic requirements can conflict: cases where an agent’s higher-order evidence supports doubting her reliability in reacting to her ordinary evidence. Conflicting epistemic requirements can be seen as generating epistemic dilemmas. The paper examines two ways that people have sought to recognize conflicting requirements without allowing them to generate epistemic dilemmas: separating epistemic norms into two different varieties, and positing rational indeterminacy in cases where principles conflict. It argues (...) that these views incur costs, and that the sense in which they avoid dilemmas does not gain them an advantage over a view that simply recognizes dilemmas as a natural outgrowth of agents’ rational reflection on their own thinking.

Building on recent formal work by Aleks Knoks, we explore how the idea that certain epistemic norms may be indeterminate could be implemented in a default logic.
