Epistemic contextualism is one of the most hotly debated topics in contemporary epistemology. Contextualists claim that ‘know’ is a context-sensitive verb associated with different evidential standards in different contexts. Contextualists motivate their view based on a set of behavioural claims. In this paper, I show that several of these behavioural claims are false. I also show that contextualist test cases suffer from a critical confound, which derives from people's tendency to defer to speakers’ statements about their own mental states. My (...) |

A long line of epistemologists including Sosa (2021), Feldman (2002), and Chisholm (1977) have argued that, at least for a certain class of questions that we take up, we should (or should aim to) close inquiry iff by closing inquiry we would meet a unique epistemic standard. I argue that no epistemic norm of this general form is true: there is not a single epistemic standard that demarcates the boundary between inquiries we are forbidden and obligated to close. In short, (...) |

Knowledge is good, ignorance is bad. So it seems, anyway. But in this dissertation, I argue that some ignorance is epistemically valuable. Sometimes, we should suspend judgment even though by believing we would achieve knowledge. In this apology for ignorance (ignorance, that is, of a certain kind), I defend the following four theses: 1) Sometimes, we should continue inquiry in ignorance, even though we are in a position to know the answer, in order to achieve more than mere knowledge (e.g. (...) |

This article develops and defends a full account of the nature and normativity of resistance to evidence, according to which resistance to evidence is an instance of input-level epistemic malfunctioning. At the core of this epistemic normative picture lies the notion of knowledge indicators, as evidential probability increasing facts that one is in a position to know; resistance to evidence is construed as a failure to uptake knowledge indicators. |

There are two central kinds of epistemological mistakes: believing things you shouldn’t, and failing to believe things that you should. The knowledge-first program offers a canonical explanation for the former: if you believe something without knowing it, you violate the norm to believe only that which you know. But the explanation does not extend in any plausible way to a story about what’s wrong with suspending judgment when one ought to believe. In this paper I explore prospects for a knowledge-centering (...) |

Why engage in inquiry? According to many philosophers, the goal of inquiring into some question is to come to know its answer. While this view holds considerable appeal, this paper argues that it stands in tension with another highly attractive thesis: knowledge does not require absolute certainty. Forced to choose between these two theses, I argue that we should reject the idea that inquiry aims at knowledge. I go on to develop an alternative view, according to which inquiry aims at (...) |

I argue that fallibilism, single-premise epistemic closure, and one formulation of the “knowledge-action principle” are inconsistent. I will consider a possible way to avoid this incompatibility, by advocating a pragmatic constraint on belief in general, rather than just knowledge. But I will conclude that this is not a promising option for defusing the problem. I do not argue here for any one way of resolving the inconsistency. |

In a recent paper, Jie Gao (Synthese 194:1901–17, 2017) has argued that there are acceptance-based counterexamples to the knowledge norm for practical reasoning (KPR). KPR tells us that we may only rely on known propositions in practical reasoning, yet there are cases of practical reasoning in which we seem to permissibly rely on merely accepted propositions, which fail to constitute knowledge. In this paper, I will argue that such cases pose no threat to a more broadly conceived knowledge-based view of (...) |

Defined narrowly, epistemology is the study of knowledge and justified belief. As the study of knowledge, epistemology is concerned with the following questions: What are the necessary and sufficient conditions of knowledge? What are its sources? What is its structure, and what are its limits? As the study of justified belief, epistemology aims to answer questions such as: How we are to understand the concept of justification? What makes justified beliefs justified? Is justification internal or external to one's own mind? (...) |

Many philosophers claim that interesting forms of epistemic evaluation are insensitive to truth in a very specific way. Suppose that two possible agents believe the same proposition based on the same evidence. Either both are justified or neither is; either both have good evidence for holding the belief or neither does. This does not change if, on this particular occasion, it turns out that only one of the two agents has a true belief. Epitomizing this line of thought are thought (...) |

According to the Book of Common Prayer, we have sinned against God “in thought, word, and deed.” In this paper I’ll explore one way of understanding what it might mean to sin against God in thought—the idea that we can at least potentially wrong God by what we believe. I will be interested in the philosophical tenability of this idea, and particularly in its potential consequences for the epistemology of religious belief and the problem of evil. |

Radical moral encroachment is the view that belief itself is morally evaluable, and that some moral properties of belief itself make a difference to epistemic rationality. To date, almost all proponents of radical moral encroachment hold to an asymmetry thesis: the moral encroaches on rational belief, but not on rational credence. In this paper, we argue against the asymmetry thesis; we show that, insofar as one accepts the most prominent arguments for radical moral encroachment on belief, one should likewise accept (...) |

Several authors have recently suggested that moral factors and norms `encroach' on the epistemic, and because of salient parallels to pragmatic encroachment views in epistemology, these suggestions have been dubbed `moral encroachment views'. This paper distinguishes between variants of the moral encroachment thesis, pointing out how they address different problems, are motivated by different considerations, and are not all subject to the same objections. It also explores how the family of moral encroachment views compare to classical pragmatic encroachment accounts. |

Historical patterns of discrimination seem to present us with conflicts between what morality requires and what we epistemically ought to believe. I will argue that these cases lend support to the following nagging suspicion: that the epistemic standards governing belief are not independent of moral considerations. We can resolve these seeming conflicts by adopting a framework wherein standards of evidence for our beliefs to count as justified can shift according to the moral stakes. On this account, believing a paradigmatically racist (...) |

You shouldn’t have done it. But you did. Against your better judgment you scrolled to the end of an article concerning the state of race relations in America and you are now reading the comments. Amongst the slurs, the get-rich-quick schemes, and the threats of physical violence, there is one comment that catches your eye. Spencer argues that although it might be “unpopular” or “politically incorrect” to say this, the evidence supports believing that the black diner in his section will (...) |

Several authors have recently endorsed the thesis that there is what has been called pragmatic encroachment on knowledge—in other words, that two people who are in the same situation with respect to truth-related factors may differ in whether they know something, due to a difference in their practical circumstances. This paper aims not to defend this thesis, but to explore how it could be true. What I aim to do, is to show how practical factors could play a role in (...) |

Simon Keller and Sarah Stroud have both argued that the demands of being a good friend can conflict with the demands of standard epistemic norms. Intuitively, good friends will tend to seek favorable interpretations of their friends’ behaviors, interpretations that they would not apply to strangers; as such they seem prone to form unjustified beliefs. I argue that there is no such clash of norms. In particular, I argue that friendship does not require us to form beliefs about our friends (...) |

It has been alleged that the demands of friendship conflict with the norms of epistemology—in particular, that there are cases in which the moral demands of friendship would require one to give a friend the benefit of the doubt, and thereby come to believe something in violation of ordinary epistemic standards on justified or responsible belief :329–351, 2004; Stroud in Ethics 116:498–524, 2006; Hazlett in A luxury of the understanding: on the value of true belief, Oxford University Press, Oxford, 2013).

Faced with evidence that what a person said is false, we can nevertheless trust them and so believe what they say – choosing to give them the benefit of the doubt. This is particularly notable when the person is a friend, or someone we are close to. Towards such persons, we demonstrate a remarkable epistemic partiality. We can trust, and so believe, our friends even when the balance of the evidence suggests that what they tell us is false. And insofar (...) |

Impurism says that practical factors encroach on knowledge. An important version of impurism is called ‘Threshold-Impurism,’ which says that practical factors encroach on the threshold that rational credence must pass in order for one to have knowledge. A prominent kind of argument for Threshold-Impurism is the so-called ‘principle-based argument,’ which relies on a principle of fallibilism and a knowledge-action principle. This paper offers a new challenge against Threshold-Impurism. I attempt to show that the two principles Threshold-Impurists are committed to—KJ and (...) |

One famous debate in contemporary epistemology considers whether there is always one unique, epistemically rational way to respond to a given body of evidence. Generally speaking, answering “yes” to this question makes one a proponent of the Uniqueness thesis, while those who answer “no” are called “permissivists”. Another influential recent debate concerns whether non-truth-related factors can be the basis of epistemic justification, knowledge, or rational belief. Traditional theories answer “no”, and are therefore considered “purists”. However, more recently many theorists have (...) |

Attributor contextualism and subject-sensitive invariantism both suggest ways in which our concept of knowledge depends on a context. Both offer approaches that incorporate traditionally non-epistemic elements into our standards for knowledge. But neither can account for the fact that the social role of a subject affects the standards that the subject must meet in order to warrant a knowledge attribution. I illustrate the dependence of the standards for knowledge on the social roles of the knower with three types of examplesand (...) |

I distinguish two different kinds of practical stakes associated with propositions. The W-stakes track what is at stake with respect to whether the proposition is true or false. The A-stakes track what is at stake with respect to whether an agent believes the proposition. This poses a dilemma for those who claim that whether a proposition is known can depend on the stakes associated with it. Only the W-stakes reading of this view preserves intuitions about knowledge-attributions, but only the A-stakes (...) |

For many epistemologists, and for many philosophers more broadly, it is axiomatic that rationality requires you to take the doxastic attitudes that your evidence supports. Yet there is also another current in our talk about rationality. On this usage, rationality is a matter of the right kind of coherence between one's mental attitudes. Surprisingly little work in epistemology is explicitly devoted to answering the question of how these two currents of talk are related. But many implicitly assume that evidence -responsiveness (...) |

It is standard, both in the philosophical literature and in ordinary parlance, to assume that one can fall short of responding to all one’s moral reasons without being irrational. Yet when we turn to epistemic reasons, the situation could not be more different. Most epistemologists take it as axiomatic that for a belief to be rational is for it to be well-supported by epistemic reasons. We find ourselves with a striking asymmetry, then, between the moral and epistemic domains concerning what (...) |

In discussions of whether and how pragmatic considerations can make a difference to what one ought to believe, two sets of cases feature. The first set, which dominates the debate about pragmatic reasons for belief, is exemplified by cases of being financially bribed to believe (or withhold from believing) something. The second set, which dominates the debate about pragmatic encroachment on epistemic justification, is exemplified by cases where acting on a belief rashly risks some disastrous outcome if the belief turns (...) |

Can you rationally double-check what you already know? In this paper, I argue that you can. Agents can know that something is true and rationally double-check it at the very same time. I defend my position by considering a wide variety of cases where agents double-check their beliefs to gain epistemic improvements beyond knowledge. These include certainty, epistemic resilience, and sensitivity to error. Although this phenomenon is widespread, my proposal faces two types of challenges. First, some have defended ignorance norms, (...) |

In this paper, we argue that there are epistemic norms on evidence-gathering and consider consequences for how to understand epistemic normativity. Though the view that there are such norms seems intuitive, it has found surprisingly little defense. Rather, many philosophers have argued that norms on evidence-gathering can only be practical or moral. On a prominent evidentialist version of this position, epistemic norms only apply to responding to the evidence one already has. Here we challenge the orthodoxy. First, we argue that (...) |

The five commentators on my paper ‘Gettier Cases in Epistemic Logic’ (GCEL) demonstrate how fruitful the topic can be. Especially in Brian Weatherson's contribution, and to some extent in those of Jennifer Nagel and Jeremy Goodman, much of the material constitutes valuable development and refinement of ideas in GCEL, rather than criticism. In response, I draw some threads together, and answer objections, mainly those in the papers by Stewart Cohen and Juan Comesaña and by Goodman. |

According to the doctrine of infallibility, one is permitted to believe p if one knows that necessarily, one would be right if one believed that p. This plausible principle—made famous in Descartes’ cogito—is false. There are some self-fulfilling, higher-order propositions one can’t be wrong about but shouldn’t believe anyway: believing them would immediately make one's overall doxastic state worse. |

In a paper in this journal, I defend the view that truth is the fundamental norm for assertion and, in doing so, reject the view that knowledge is the fundamental norm for assertion. In a recent response, Littlejohn raises a number of objections against my arguments. In this reply, I argue that Littlejohn’s objections are unsuccessful. |

It is commonplace to claim that it is good to believe the truth. In this paper, I reject that claim and argue that the considerations which might seem to support it in fact support a quite distinct though superficially similar claim, namely, that it is bad to believe the false. This claim is typically either ignored completely or lumped together with the previous claim, perhaps on the assumption that the two are equivalent, or at least that they stand or fall (...) |

The view that truth is the norm of assertion has fallen out of fashion. The recent trend has been to think that knowledge is the norm of assertion. Objections to the knowledge view proceed almost exclusively by appeal to alleged counterexamples. While it no doubt has a role to play, such a strategy relies on intuitions concerning hypothetical cases, intuitions which might not be shared and which might shift depending on how the relevant cases are fleshed out. In this paper, (...) |

In a recent set of publications Ballantyne :485–503, 2011, Synthese 185:319–334, 2012, Synthese 91:1391–1407, 2013) argues that luck does not have a significant role in understanding the concept of knowledge. The problem, Ballantyne argues, lies in what is commonly thought to be a necessary condition for luck—a significance or value condition :385–398, 2007; Lackey, in Austral J Philos 86:255–267, 2008, Ballantyne, in Can J Philos 41:485–503, 2011). For an event, like forming a true belief, to be lucky then it must (...) |

An influential proposal is that knowledge involves safe belief. A belief is safe, in the relevant sense, just in case it is true in nearby metaphysically possible worlds. In this paper, I introduce a distinct but complementary notion of safety, understood in terms of epistemically possible worlds. The main aim, in doing so, is to add to the epistemologist’s tool-kit. To demonstrate the usefulness of the tool, I use it to advance and assess substantive proposals concerning knowledge and justification. |

The notion of a proposition is central to philosophy. But it is subject to paradoxes. A natural response is a hierarchical account and, ever since Russell proposed his theory of types in 1908, this has been the strategy of choice. But in this paper I raise a problem for such accounts. While this does not seem to have been recognized before, it would seem to render existing such accounts inadequate. The main purpose of the paper, however, is to provide a (...) |

Here are two plausible ideas about belief. First: beliefs are our means of storing information. Second: if we believe something, then we are willing to use it in reasoning. But in this paper I introduce a puzzle that seems to show that these cannot both be right. The solution, I argue, is a new picture, on which there is a kind of belief for each idea. An account of these two kinds of belief is offered in terms of two components: (...) |

A normative reason for a person to? is a consideration which favours?ing. A motivating reason is a reason for which or on the basis of which a person?s. This paper explores a connection between normative and motivating reasons. More specifically, it explores the idea that there are second-order normative reasons to? for or on the basis of certain first-order normative reasons. In this paper, I challenge the view that there are second-order reasons so understood. I then show that prominent views (...) |

At the centenary of Frank H. Knight’s Risk, Uncertainty, and Profit (1921), we explore the continuing relevance of Knightian uncertainty to the theory and practice of entrepreneurship. There are three challenges facing such assessment. First, RUP is complex and difficult to interpret. The key but neglected element of RUP is that Knight’s account is not solely about risk and uncertainty as states of nature, but about how an agent’s beliefs about uncertain outcomes and confidence in those beliefs guide their choices.

Recently, Timothy Williamson has argued that considerations about margins of errors can generate a new class of cases where agents have justified true beliefs without knowledge. I think this is a great argument, and it has a number of interesting philosophical conclusions. In this note I’m going to go over the assumptions of Williamson’s argument. I’m going to argue that the assumptions which generate the justification without knowledge are true. I’m then going to go over some of the recent arguments (...) |

Pragmatic encroachment theories have a problem with evidence. On the one hand, the arguments that knowledge is interest-relative look like they will generalise to show that evidence too is interest-relative. On the other hand, our best story of how interests affect knowledge presupposes an interest-invariant notion of evidence. -/- The aim of this paper is to sketch a theory of evidence that is interest-relative, but which allows that ‘best story’ to go through with minimal changes. The core idea is that (...) |

I defend interest-relative invariantism from a number of recent attacks. One common thread to my response is that interest-relative invariantism is a muchweaker thesis than is often acknowledged, and a number of the attacks only challenge very specific, and I think implausible, versions of it. Another is that a number of the attacks fail to acknowledge how many things we have independent reason to believe knowledge is sensitive to. Whether there is a defeater for someone's knowledge can be sensitive to (...) |

In this paper, we claim that, if you justifiably believe that you ought to perform some act, it follows that you ought to perform that act. In the first half, we argue for this claim by reflection on what makes for correct reasoning from beliefs about what you ought to do. In the second half, we consider a number of objections to this argument and its conclusion. In doing so, we arrive at another argument for the view that justified beliefs (...) |

Intellectualists claim that knowing how to do something is a matter of knowing, for some w, that w is a way to do that thing. However, standard accounts fail to account for the way that knowing how sometimes seems to require ability. I argue that the way to make sense of this situation is via a ‘subject-specific’ intellectualism according to which knowing how to do something is a matter of knowing that w is a way for some relevant person to (...) |

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 (...) |

The traditional view in epistemology has it that knowledge is insensitive to the practical stakes. More recently, some philosophers have argued that knowledge is sufficient for rational action: if you know p, then p is a reason you have (epistemically speaking). Many epistemologists contend that these two claims stand in tension with one another. In support of this, they ask us to start with a low stakes case where, intuitively, a subject knows that p and appropriately acts on p. Then, (...) |
