Epistemic Internalism and Externalism

Mind and body have been reunited by the "affective turn" in philosophy and (neuro-) psychology. Yet, for centuries they have been painstakingly kept apart, for a specific reason. Methodologically, to find out about the world, apply justice or follow news, independent confirmation has always been indispensable. As it turns out, it also plays an important role in our personal everyday lives, to stay away from depersonalization- or derealization disorders and mainly to become and stay happy.

Abstract: Scepticism about the normativity of rationality is often partially based on the assumption that normative reasons are normative. Starting from the assumption that normative reasons are normative, someone will argue that reasons and rationality can require different things from us and conclude that rationality must not be normative. We think that the assumption that normative reasons are normative is one that deserves more scrutiny, particularly if it turns out, as we shall argue, that no one has yet shown that (...) the requirements of reasons and rationality might be unified. We look at the most promising proposals about how to unite the requirements of reasons and rationality and argue that they cannot succeed. In the course of doing so, we discuss a case that we think gives us good reason to think that good reasons are not the things that determine in each case what we ought to believe and/or do. We argue that the best way to deal with the examples discussed here might be to appeal to principles of rationality and acknowledge that following their guidance will not invariably ensure that we do what normative reasons (as they are usually understood) support. We think that it might just follow that normative reasons (as they are usually understood) cannot be the things that determine what would be rational to do or what we ought to do. (shrink)

The New Demon World Objection claims that reliabilist accounts of justification are mistaken because there are justified empirical beliefs at demon worlds—worlds at which the subjects are systematically deceived by a Cartesian demon. In this paper, I defend strongly verific (but not necessarily reliabilist) accounts of justification by claiming that there are two ways to construct a theory of justification: by analyzing our ordinary concept of justification or by taking justification to be a theoretic term defined by its role in (...) the theory of knowledge. The former route is not promising because of the splintered nature of our ordinary concept of justification—or perhaps because there is no single such concept. On the other hand, if justification is defined by the role it plays in the theory of knowledge, then there is good reason to think that justification must be strongly truth-conductive since the term was introduced by Edmund Gettier to play the primary role in converting true belief into knowledge. And if that is right, then there will be no justified empirical belief at demon worlds. The real lesson of the demon world is then turned on its head: justification does not supervene on what one shares with one’s deceived doppelganger. (shrink)

An internalist slogan says that justification depends on internal factors. But which factors are those? This paper examines some common motivations favoring internalism over externalism, and says they are compatible with including dispositional and even past mental states in the internal.

One leading account of justification comes from the evidentialist tradition. According to evidentialists, whether a doxastic attitude is justified depends on whether that attitude is supported by the believer’s evidence. This chapter assesses the prospects for evidentialism, focusing on the question of whether evidentialists can provide a satisfactory account of their key notions – evidence possession and evidential support – without helping themselves to the notion of justification.

Some moral value is transparent just in case an agent with average mental capacities can feasibly come to know whether some entity does, or does not, possess that value. In this paper, I consider whether legitimacy—that is, the property of exercises of political power to be permissible—is transparent. Implicit in much theorising about legitimacy is the idea that it is. I will offer two counter-arguments. First, injustice can defeat legitimacy, and injustice can be intransparent. Second, legitimacy can play a critical (...) function in our practical thought, which sometimes requires intransparency. (shrink)

The traditional view in epistemology is that we must distinguish between being rational and being right (that is also, by the way, the traditional view about practical rationality). In his paper in this volume, Williamson proposes an alternative view according to which only beliefs that amount to knowledge are rational (and, thus, no false belief is rational). It is healthy to challenge tradition, in philosophy as much as elsewhere. But, in this instance, we think that tradition has it right. In (...) this paper we defend our version of the traditional view and argue against Williamson’s alternative. (shrink)

In this essay, I cast doubt on an apparent truism: namely, that if evidence is available for gathering and use at a negligible cost, then it's always instrumentally rational for us to gather that evidence and use it for making decisions. Call this thesis Value of Information. I show that Value of Information conflicts with two other plausible theses. The first is the view that an agent's evidence can entail non-trivial propositions about the external world. The second is the view (...) that epistemic rationality requires us to update our credences by conditionalization. These two theses, given some plausible assumptions, make room for rationally biased inquiries where Value of Information fails. I go on to argue that this is bad news for defenders of Value of Information. (shrink)

Knowledge-first evidentialism combines the view that it is rational to believe what is supported by one's evidence with the view that one's evidence is what one knows. While there is much to be said for the view, it is widely perceived to fail in the face of cases of reasonable error—particularly extreme ones like new Evil Demon scenarios (Wedgwood, 2002). One reply has been to say that even in such cases what one knows supports the target rational belief (Lord, 201x, (...) this volume). I spell out two versions of the strategy. The direct one uses what one knows as the input to principles of rationality such as conditionalization, dominance avoidance, etc. I argue that it fails in hybrid cases that are Good with respect to one belief and Bad with respect to another. The indirect strategy uses what one knows to determine a body of supported propositions that is in turn the input to principles of rationality. I sketch a simple formal implementation of the indirect strategy and show that it avoids the difficulty. I conclude that the indirect strategy offers the most promising way for knowledge-first evidentialists to deal with the New Evil Demon problem. (shrink)

Considerations of scientific evidence are often thought to provide externalism with the dialectical upper hand in the internalism–externalism debate. How so? A couple of reasons are forthcoming in the literature. (1) Williamson (2000) argues that the E = K thesis (in contrast to internalism) provides the best explanation for the fact that scientists appear to argue from premises about true propositions (or facts) that are common knowledge among the members of the scientific community. (2) Kelly (Philosophy Compass, 3 (5), 933–955, (...) 2008; 2016) argues that only externalism is suited to account for the public character of scientific evidence. In this article, I respond to Williamson and Kelly’s arguments. First, I show that the E = K thesis isn’t supported by the way in which we talk about scientific evidence, and that it is unable to account for facts about what has been regarded as scientific evidence and as justified scientific belief in the history of science. Second, I argue that there are internalist views that can account for the publicity of scientific evidence, and that those views indeed do better in that regard than the (externalist) view proposed by Kelly. The upshot is that considerations of scientific evidence do not favor externalism over internalism. (shrink)

Our aim in this chapter is to contribute to a greater appreciation of Bourdieu’s work within debates on embodied, extended and distributed cognition, grouped under the general heading of externalism (Rowlands 2003, Carter et al. 2014). We seek to draw out several pertinent elements of Bourdieu’s theory of social practice, and show how they variously resonate with, enrich, or problematize key externalist theses. We begin with an overview of the main elements of Bourdieu’s theoretical enterprise, in order to provide essential (...) background for the ensuing discussion. We then address a number of themes connecting Bourdieu’s theory with facets of cognitive externalism, which we organize under the headings of diachronic co-dependence, instrumental dependence, and co-constitutive dependence. Following this we turn our attention to epistemic externalism, where we find promising ground for dialogue with Bourdieu in recent developments in virtue epistemology, focusing our analysis on a recent proposal concerning knowledge-how by Carter & Pritchard (2015). We conclude with an assessment of Bourdieu’s standing with respect to these currents, and prospects for further engagement. (shrink)

According to the ‘Evidential Internalists’, one’s evidence supervenes on one’s non-factive mental states. ‘Evidential Externalists’ deny that, and allow for external factors to determine what evidence one has. After clarifying what Evidential Internalism and Evidential Externalism entail, and what they are silent on, this chapter provides an opinionated overview of the main arguments and motivations behind Evidential Internalism and Evidential Externalism. It concludes that Evidential Externalism is a more promising view.

Tyler Burge first introduced his distinction between epistemic entitlement and epistemic justification in ‘Content Preservation’ in 1993. He has since deployed the distinction in over twenty papers, changing his formulation around 2009. His distinction and its basis, however, is not well understood in the literature. This chapter distinguishes two uses of ‘entitlement’ in Burge, and then focuses on his distinction between justification and entitlement, two forms of warrant, where warrants consists in the exercise of a reliable belief-forming competence. Since he (...) draws the distinction in terms of reasons, this chapter brings his account of reasons altogether in one place. The chapter introduces a decision-procedure for classifying warrants as justifications or entitlements. The distinction between justification and entitlement is not the same as the inferential vs. non-inferential distinction. The chapter distinguishes inference from processing, thinking, reasoning, and critically reasoning. Burge’s new formulation of the distinction was driven by the recognition of non-accessible modular reasons. Three kinds of access are distinguished. (shrink)

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.

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)

What kinds of mental states can be based on epistemic reasons? The standard answer is only beliefs. I argue that perceptual states can also be based on reasons, as the result of crossmodal interactions. A perceptual state from one modality can provide a reason on which an experience in another modality is based. My argument identifies key markers of the basing relation and locates them in the crossmodal Marimba Illusion. The subject’s auditory experience of musical tone duration is based on (...) the reason provided by her visual representation of the length of the musician’s gesture and other stored perceptual principles. (shrink)

Perceptual experiences are not immediately responsive to reasons. You see a stick submerged in a glass of water as bent no matter how much you know about light refraction. Due to this isolation from reasons, perception is traditionally considered outside the scope of epistemic evaluability as justified or unjustified. Is perception really as independent from reasons as visual illusions make it out to be? I argue no, drawing on psychological evidence from perceptual learning. The flexibility of perceptual learning is a (...) way of responding to new epistemic reasons. The resulting perceptual experiences are epistemically evaluable as justified or unjustified. (shrink)

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!).).

A discussion of epistemic reasons, theoretical rationality, and the relationship between them. Discusses the ontology of reasons and evidence, the relationship between reasons (motivating, normative, possessed, apparent, genuine, etc.) and rationality, the relationship between epistemic reasons and evidence, the relationship between rationality, justification, and knowledge, and many other related topics.

The typical epistemology course begins with a discussion of the distinction between justification and knowledge and ends without any discussion of the distinction between justification and excuse. This is unfortunate. If we had a better understanding of the justification-excuse distinction, we would have a better understanding of the intuitions that shape the internalism-externalism debate. My aims in this paper are these. First, I will explain how the kinds of excuses that should interest epistemologists exculpate. Second, I will explain why the (...) intuitions that underwrite the new evil demon argument don't provide support for the internalist claim that justification is just in the head. The positive response that Cohen's example elicits is an indication that the subject should be excused if she violates an epistemic norm, not an indication that no norm has been violated. For just about any conceivable norm we can think of we can imagine situations in which someone violates that norm because they're moved by evidence that misleadingly suggests that they'd conform to it. When that happens, we'll respond positively in just the way we do when we consider Cohen's deceived subjects. When that happens, we cannot say that the subjects' responses were justified because we've stipulated that the subjects' responses contravene the relevant norms. Regardless of whether you think of norms along internalist or externalist lines, you should see that the intuitions that underwrite the new evil demon objection tell us nothing at all about whether a subject conforms to a norm. They tell us nothing about justification. (shrink)

There is a kind of objectivism in epistemology that involves the acceptance of objective epistemic norms. It is generally regarded as harmless. There is another kind of objectivism in epistemology that involves the acceptance of an objectivist account of justification, one that takes the justification of a belief to turn on its accuracy. It is generally regarded as hopeless. It is a strange and unfortunate sociological fact that these attitudes are so prevalent. Objectivism about norms and justification stand or fall (...) together. Justification is simply a matter of conforming to norms. In this essay, I shall make the case for objectivism about justification. (shrink)

I argue that justification isn't just in the head. The argument is simple. We should be guided by our beliefs. We shouldn't be guided by anything to do what we shouldn't do. So, we shouldn't believe in ways that would guide us to do the things that we shouldn't. Among the various things we should do is discharge our duties (e.g., to fulfil our promissory obligations) and respect the rights of others (e.g., rights not to be harmed or killed by (...) agents acting on bad information). The grounds of our duties and obligations aren't just in the head. Thus, the conditions that bear on the justification of our beliefs cannot be contained wholly in our heads. The internalist might be right about aspects of normativity, but their theories tell us important normative truths without telling us the whole truth. In addition to norms that tell us how to process information, there are norms that tell us how we ought to live together. In information-asymmetry cases, these norms clearly come apart. Important normative questions about what we should do when agents (who, we might suppose, do what they subjectively ought to do) have interests that come into conflict can only be answered by externalist theories that recognise information-transcendent norms and normatively significant relations that don't supervene upon the information of any agent in particular. The internalist picture turns out to be disturbing precisely because it falls silent when we're faced with questions about how to resolve these conflicts. Resolving these conflicts should be a pressing concern for every normative theory. (shrink)

A theory of what we should believe should include a theory of what we should believe when we are uncertain about what we should believe and/or uncertain about the factors that determine what we should believe. In this paper, I present a novel theory of what we should believe that gives normative externalists a way of responding to a suite of objections having to do with various kinds of error, ignorance, and uncertainty. This theory is inspired by recent work in (...) ethical theory in which non-consequentialists 'consequentialize' their theories and then use the tools of decision-theory to give us an account of what we ought (in some sense) to do when we're uncertain about what we ought (in some primary sense) to do. On my proposal, because what we ought to do is acquire knowledge and avoid ignorance, we ought to believe iff the probability of coming to know is sufficiently high. This view has a number of important virtues. Among them, it gives us a unified story about how defeaters defeat (a theory developed with Julien Dutant), explains puzzling intuitions about the differences between lottery cases, preface cases, and cases of perceptual knowledge, and provides externalists (and internalists!) with a general framework for thinking about subjective normativity. It's also relatively brief. (shrink)

A theory of rational belief should get the cases right. It should also reach its verdicts using the right reasons. Leading theories seem to predict the wrong things. With only one exception, they don't accommodate principles that we should use to explain these verdicts. We offer a theory of rational belief that combines an attractive picture of epistemic desirability with plausible principles connecting desirability to rationality. The theory predicts intuitively compelling verdicts and, importantly, seems to use the right principles to (...) reach them. (shrink)

Is truth the rule or the aim of assertions? Philosophers disagree. After reviewing the available evidence, the hypothesis that truth is the aim of assertion is defended against recent attempts to prove that truth is rather a rule of assertion.

I extend my direct virtue epistemology to explain how a knowledge-first framework can account for two kinds of positive epistemic standing, one tracked by externalists, who claim that the virtuous duplicate lacks justification, the other tracked by internalists, who claim that the virtuous duplicate has justification, and moreover that such justification is not enjoyed by the vicious duplicate. It also explains what these kinds of epistemic standing have to do with each other. I argue that all justified beliefs are good (...) candidates for knowledge, and are such because they are exercises of competences to know. However, there are two importantly different senses in which a belief may be a good candidate for knowledge, one corresponding to an externalist kind of justification and the other corresponding to an internalist one. I show how the account solves the new evil demon problem in a more satisfactory way than existing accounts. We end up with a view of knowledge, justification, and rationality that is plausible, motivated, and theoretically unified. (shrink)

Abstracting away from its various particular versions, contemporary externalism about knowledge can be broadly characterized as the rejection of two central ideas: that knowledge is incompatible with reflective awareness of the possibility of error, and that knowledge is necessarily tied to the resources that are available from within the first-person perspective. In this brief introduction, I outline five distinctly externalist accounts of knowledge, and two distinctly externalist methodological approaches to knowledge, all fitting this general description.

This essay aims to motivate an epistemic non-individualistic conception of reflection. The proposal is non-individualistic because (a) it addresses more than individual metacognitive performance and (b) it refers to a situation in which two or more people are in dialogical disagreement about the same subject matter or target proposition; (c) their dispute is based on conversational space and they are entitled to expect one another to be engaged in attempts at truth, avoidance of error, and understanding. I call this proposal (...) a Dialectical account of Reflection (DaR). According to (DaR), reflection is a conscious and intentional intellectual operation through which an individual becomes aware of the contents of disputed beliefs in a dialogical or interpersonal exchange, involving both her own beliefs and the beliefs of her interlocutors. In (DaR), reflection produces the epistemic good of avoiding epistemic vices and promoting epistemic moderation. (shrink)

The New Evil Demon Problem presents a serious challenge to externalist theories of epistemic justification. In recent years, externalists have developed a number of strategies for responding to the problem. A popular line of response involves distinguishing between a belief’s being epistemically justified and a subject’s being epistemically blameless for holding it. The apparently problematic intuitions the New Evil Demon Problem elicits, proponents of this response claim, track the fact that the deceived subject is epistemically blameless for believing as she (...) does, not that she is justified for so believing. This general strategy—which I call the “unjustified-but-blameless maneuver”—is motivated, in part, by the assumption that the distinction between epistemic justification and blamelessness is merely an extension of the familiar distinction between moral justification and blamelessness. In this paper, I consider three ways of drawing the distinction between justification and blamelessness familiar from the moral domain: the first in terms of a connection with reactive attitudes, the second in terms of the distinction between wrongness and wronging, and the third in terms of reasons-responsiveness. All three ways of drawing the distinction, I argue, make it difficult to see how an analogous distinction in the epistemic domain could help externalists explain away the intuitions which underwrite the New Evil Demon Problem. Motivating the unjustified-but-blameless maneuver, I conclude, is a much less straightforward task than its proponents tend to assume. (shrink)

There is a large literature exploring how accuracy constrains rational degrees of belief. This paper turns to the unexplored question of how accuracy constrains knowledge. We begin by introducing a simple hypothesis: increases in the accuracy of an agent’s evidence never lead to decreases in what the agent knows. We explore various precise formulations of this principle, consider arguments in its favor, and explain how it interacts with different conceptions of evidence and accuracy. As we show, the principle has some (...) noteworthy consequences for the wider theory of knowledge. First, it implies that an agent cannot be justified in believing a set of mutually inconsistent claims. Second, it implies the existence of a kind of epistemic blindspot: it is not possible to know that one’s evidence is misleading. (shrink)

According to Bayesian orthodoxy, an agent should update---or at least should plan to update---her credences by conditionalization. Some have defended this claim by means of a diachronic Dutch book argument. They say: an agent who does not plan to update her credences by conditionalization is vulnerable (by her own lights) to a diachronic Dutch book, i.e., a sequence of bets which, when accepted, guarantee loss of utility. Here, I show that this argument is in tension with evidence externalism, i.e., the (...) view that an agent's evidence can entail non-trivial propositions about the external world. I argue that this tension casts doubt on the idea that diachronic Dutch books can be used to justify or vindicate updating plans. (shrink)

Sven Rosenkranz’s Justification as Ignorance shows how a strongly internalist conception of justification can be derived from a strongly externalist conception of knowledge, given an identification of justification with second-order ignorance and a set of structural principles concerning knowing and being in a position to know. Among these principles is an epistemic analogue of the Geach modal schema which states that one is always in a position to know that one doesn’t know p or in a position to know that (...) one doesn’t know not-p. Even suitably refined, the principle faces a range of counterexamples in which it misleadingly and persistently seems to one that one knows whether p without it seeming to one that one knows p nor that one knows not-p. These cases also threaten the book’s case for the luminosity of second-order ignorance, which is in turn central to its derivation of strongly internalist principles of justification. (shrink)

According to the seventh-century C.E. philosopher Kumārila Bhat.t.a, epistemic agents are warranted in taking their world-presenting experiences as veridical, if they lack defeaters. For him, these experiences are defeasibly sources of knowledge without the agent reflecting on their content or investigating their causal origins. This position is known as svatah prāmāṇya in Sanskrit (henceforth the SP principle). -/- As explicated by the eleventh-century commentator, Pārthasārathi Misŕa, this position entails that epistemic agents know things without simultaneously knowing that they know them, (...) or being in a position to know that they know. In contrast, some contemporary Anglo-analytic philosophers argue for the “knows-knows principle” (KK principle), in which if someone knows that p, then that person also knows that they know that p, or that person is in a position to know that they know p. Despite some apparent similarities, the SP principle is not a version of the KK principle, nor would Pārthasārathi’s Kumārila have held the KK principle. -/- Recently, Daniel Immerman (2018) has argued that the SP principle is a position-to-know version of the “knows-knows principle” (KK-pos principle). By examining Kumārila’s response to his Buddhist opponent, who challenges the veracity of Vedic testimony, we will see that Kumārila understands higher-order knowing as involving an independent check on one’s epistemic processes, through an epistemic instrument known as postulation (arthāpatti). This precludes him from holding the KK-pos principle. (shrink)

Smithies presents an account of justification that ties it to an idealized view of reflection. I argue that no such account can work. More than this, I argue that the kind of idealization which Smithies offers loses contact with the very phenomenon of reflection which he intends to illuminate. I also discuss how Smithies's view bears on the internalism/externalism controversy.

In Fallibilism: Evidence and Knowledge, Jessica Brown identifies a number of problems for the so-called knowledge view of justification. According to this view, we cannot justifiably believe what we do not know. Most epistemologists reject this view on the grounds that false beliefs can be justified if, say, supported by the evidence or produced by reliable processes. We think this is a mistake and that many epistemologists are classifying beliefs as justified because they have properties that indicate that something should (...) be excused. Brown thinks that previous attempts to make this case have been unsuccessful. While the difficulties Brown points to are genuine, I think they show that attempts to explain a classificatory judgment haven't been successful. Still, I would argue that the classification is correct. We need a better explanation of this classificatory judgment. I will try to clarify the justification-excuse distinction and explain why it's a mistake to insist that beliefs that violate epistemic norms might be justified. Just as it's possible for a rational agent to act without justification in spite of her best intentions, it's possible that a rational thinker who follows the evidence and meets our expectations might nevertheless believe without sufficient justification. If our justified beliefs are supposed to guide us in deciding what to do, we probably should draw on discussions from morality and the law about the justification/excuse distinction to inform our understanding of the epistemic case. (shrink)

When is a belief justified? There are three families of arguments we typically use to support different accounts of justification: arguments from our intuitive responses to vignettes that involve the concept; arguments from the theoretical role we would like the concept to play in epistemology; and arguments from the practical, moral, and political uses to which we wish to put the concept. I focus particularly on the third sort, and specifically on arguments of this sort offered by Clayton Littlejohn in (...) Justification and the Truth-Connection and Amia Srinivasan in ‘Radical Externalism’ : 395–431, 2018) in favour of externalism. I counter Srinivasan’s argument in two ways: first, I show that the internalist’s concept of justification might figure just as easily in the sorts of structural explanation Srinivasan thinks our political goals require us to give; and I argue that the internalist’s concept is needed for a particular political task, namely, to help us build more effective defences against what I call epistemic weapons. I conclude that we should adopt an Alstonian pluralism about the concept of justification. (shrink)

Philosophical orthodoxy holds that Thomas Reid is an externalist concerning epistemic justification, characterizing Reid as holding the key to an externalist response to internalism. These externalist accounts of Reid, however, have neglected his work on prejudice, a heretofore unexamined aspect of his epistemology. Reid’s work on prejudice reveals that he is far from an externalist. Despite the views Reid may have inspired, he exemplifies internalism in opting for an accessibility account of justification. For Reid, there are two normative statuses that (...) a belief might satisfy, being blameless and having a just ground. Through reflection, a rational agent is capable of satisfying both of these statuses, making Reid an accessibility internalist about epistemic justification. (shrink)

I will argue that internalism about justification entails the apparently absurd conclusion that it is possible to know specific facts about the external world—for example, that there is a tree in the quad—on the basis of introspection and a priori reflection. After a brief characterization of internalism (§1), I will set out the problem (§2). I will then discuss three replies: one that denies the form of doxastic voluntarism involved in the problem (§3), one that denies that knowledge of higher-order (...) facts about justification can justify corresponding first-order beliefs (§4), and, finally, one that involves biting the bullet (§5). I will argue that each reply fails. (shrink)

Formal models of appearance and reality have proved fruitful for investigating structural properties of perceptual knowledge. This paper applies the same approach to epistemic justification. Our central goal is to give a simple account of The Preface, in which justified belief fails to agglomerate. Following recent work by a number of authors, we understand knowledge in terms of normality. An agent knows p iff p is true throughout all relevant normal worlds. To model The Preface, we appeal to the normality (...) of error. Sometimes, it is more normal for reality and appearance to diverge than to match. We show that this simple idea has dramatic consequences for the theory of knowledge and justification. Among other things, we argue that a proper treatment of The Preface requires a departure from the internalist idea that epistemic justification supervenes on the appearances and the widespread idea that one knows most when free from error. (shrink)

Cases of inexact observations have been used extensively in the recent literature on higher-order evidence and higher-order knowledge. I argue that the received understanding of inexact observations is mistaken. Although it is convenient to assume that such cases can be modeled statically, they should be analyzed as dynamic cases that involve change of knowledge. Consequently, the underlying logic should be dynamic epistemic logic, not its static counterpart. When reasoning about inexact knowledge, it is easy to confuse the initial situation, the (...) observation process, and the result of the observation; I analyze the three separately. This dynamic approach has far reaching implications: Williamson’s influential argument against the KK principle loses its force, and new insights can be gained regarding synchronic and diachronic introspection principles. (shrink)

False beliefs and misleading evidence have striking similarities. In many regards, they are both epistemically bad or undesirable. Yet, some epistemologists think that, while one’s evidence is normative (i.e., one’s available evidence affects the doxastic states one is epistemically permitted or required to have), one’s false beliefs cannot be evidence and cannot be normative. They have offered various motivations for treating false beliefs differently from true misleading beliefs, and holding that only the latter may be evidence. I argue that this (...) is puzzling: If misleading evidence and false beliefs share so many important similarities, why treat them differently? I also argue that, given the striking similarities between false beliefs and misleading evidence, many arguments for the factivity of evidence overgeneralize. That is, if these arguments were conclusive, they would also entail that the evidence cannot be misleading. But this is an overgeneralization, since the evidence can be misleading. (shrink)

This article is about the compatibility between a form of internalism about epistemic justification and a form of externalism in the philosophy of mind called active externalism. Justification internalism in epistemology is the thesis that epistemic justification depends only on features internal to the agent. Active externalism is the position that it is possible that some of our mental states are external, i.e., constituted in part by elements “outside our head” — this form of externalism is articulated by the extended (...) mind thesis. Andy Clark and David Chalmers argued in favor of this position in “The Extended Mind” (1998). Some philosophers believe the extended mind thesis is incompatible with accessibilist internalism because of the justifying role introspection plays in this form of epistemic internalism. I argue that, despite initial appearances, the extended mind thesis is compatible with epistemic internalism; however, it might conflict with other assumptions internalists usually make. This article’s structure goes like this: (i) I present the extended mind thesis; (ii) I introduce accessibilist internalism, sometimes seen as incompatible with the previous position; (iii) I explain and evaluate different arguments regarding the compatibility between the two positions.

Public reason liberals claim that legitimate rules must be justifiable to diverse perspectives. This Public Justification Principle threatens that failing to justify rules to reprehensible agents makes them illegitimate. Although public reason liberals have replies to this objection, they cannot avoid the challenge of powerful deceivers. Powerful deceivers trick people who are purportedly owed public justification into considering otherwise good rules unjustified. Avoiding this challenge requires discounting some failures of justification according to what caused people’s beliefs. I offer a conception (...) of public justification that accommodates these externalist considerations while positioning Public Reason Liberalism to provide insight into real cases of deception.

According to Probability 1 Infallibilism (henceforth, Infallibilism), if one knows that p, then the probability of p given one’s evidence is 1. Jessica Brown (2018, 2013) has recently argued that Infallibilism leads to scepticism unless the infallibilist also endorses the claim that if one knows that p, then p is part of one’s evidence for p. By doing that, however, the infalliblist has to explain why it is infelicitous to cite p as evidence for itself. And yet, the infallibilist doesn’t (...) seem to have a satisfying explanation available. Call this the Infelicity Challenge for Probability 1 Infallibilism. By exploiting the distinction between the justifying and the motivating role of evidence, in this paper, I argue that, contrary to first appearances, the Infelicity Challenge doesn’t arise for Probability 1 Infallibilism. However, after anticipating and resisting two objections to my argument, I show that we can identify a different version of infallibilism which seems to face a problem that is even more serious than the Infelicity Challenge.

I will present a novel account of justification in terms of knowledge on which one is justified in believing p just in case one could know that p. My main aim is to unravel some of the formal properties that justification has in virtue of its connection to knowledge. Assuming that safety is at least a necessary condition for knowledge, I show that justification doesn’t iterate trivially; isn’t a luminous condition; is closed under a certain kind of multi-premise closure principle, (...) but; surprisingly one can nevertheless believe with justification a set of claims that’s jointly inconsistent. This last feature allows for a rather satisfying solution to the preface paradox. Finally, I contrast my account with other knowledge-first accounts of justification. (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.

This project is concerned with the attempt to diagnose certain types of deductive inferences as exhibiting failure of transmission of justification. The canonical example of alleged transmission failure is G. E. Moore’s infamous ‘proof’ of the external world, in which Moore reasoned here is a hand, therefore the external world exists. If the transmission failure diagnosis is correct, then this inference is incapable of providing a route to learning of its conclusion on the grounds that it is only if one (...) already has some justification to believe its conclusion that one can acquire justification for its premise. The thesis presents two novel problems for the transmission failure diagnosis. Firstly, this diagnosis is only appealing if it is able to safeguard epistemic closure, but it is unclear whether it is able to do this once we distinguish between propositional and doxastic justification. Secondly, a dilemma is presented for entitlement theory, the traditional framework for understanding how there could be justification for believing the conclusions at issue. The dilemma arises once we consider the question of what the apposite degree of confidence is that is licenced by an entitlement, the upshot of which is that either entitlement theory is unmotivated, or it leads to irrational doxastic attitudes. In light of these problems, an alternative framework for understanding the phenomenon of transmission failure is presented. This framework rejects a common assumption in the literature that we can only accommodate the phenomenon by appealing to internalist notions of justification. The resulting externalist framework is defended against two potentially devastating objections. Finally, implications for how these views regarding the structure of justification bear on issues in the epistemology of testimony are considered, and it is argued that a certain family of views in the literature on testimony are committed to certain problematic views regarding the structure of justification.
