Arguments from "easy knowledge" are meant to refute a class of epistemological views, including foundationalism about perceptual knowledge. I present arguments from easy knowledge in their strongest form, and explain why other formulations in the literature are inferior. I criticize two features of Stewart Cohen's presentation, namely his focus on knowing that one's faculties are reliable, and his use of a Williamson-style closure principle. Rather, the issue around easy knowledge must be understood using a notion of epistemic priority. Roger White's (...) presentation is contaminated by the so-called lottery puzzle, which is best kept separate. Distinguishing basic from non-basic visual contents limits the force of the examples discussed by Cohen, White, and Crispin Wright. Finally, I present a new strategy for resisting even the best-formulated arguments from easy knowledge. (shrink)

This paper explains what’s wrong with a Hume-inspired argument for skepticism about induction. Hume’s argument takes as a premise that inductive reasoning presupposes that the future will resemble the past. I explain why that claim is not plausible. The most plausible premise in the vicinity is that inductive reasoning from E to H presupposes that if E then H. I formulate and then refute a skeptical argument based on that premise. Central to my response is a psychological explanation for how (...) people judge that if E then H without realizing that they thereby settled the matter rationally. (shrink)

A sensible epistemologist may not see how she could know that she is not a brain in a vat ; but she doesn’t panic. She sticks with her empirical beliefs, and as that requires, believes that she is not a BIV. (She does not inferentially base her belief that she is not a BIV on her empirical knowledge—she rejects that ‘Moorean’ response to skepticism.) Drawing on the psychological literature on metacognition, I describe a mechanism that’s plausibly responsible for a sensible (...) epistemologist coming to believe she is not a BIV. I propose she thereby knows that she is not a BIV. The particular belief-forming mechanism employed explains why she overlooks this account of how she knows she is not a BIV, making it seem that there is no way for her to know it. I argue this proposal satisfactorily resolves the skeptical puzzle. (shrink)

One might think that its seeming to you that p makes you justified in believing that p. After all, when you have no defeating beliefs, it would be irrational to have it seem to you that p but not believe it. That view is plausible for perceptual justification, problematic in the case of memory, and clearly wrong for inferential justification. I propose a view of rationality and justified belief that deals happily with inference and memory. Appearances are to be evaluated (...) as ‘sound’ or ‘unsound.’ Only a sound appearance can give rise to a justified belief, yet even an unsound appearance can ‘rationally require’ the subject to form the belief. Some of our intuitions mistake that rational requirement for the belief’s being justified. The resulting picture makes it plausible that there are also unsound perceptual appearances. I suggest that to have a sound perceptually basic appearance that p, one must see that p. (shrink)

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)

Despite the fact that many of our beliefs are justified by perceptual experience, there is relatively little exploration of the connections between epistemic justification and perceptual content. This is unfortunate since it seems likely that some views of justification will require particular views of content, and the package of the two might be quite a bit less attractive than either view considered alone. I will argue that this is the case for epistemic internalism. In particular, epistemic internalism requires a view (...) of perceptual content that results in an error theory of perception. This, in turn, hobbles the internalist’s account of perceptual justification. While there are various stages along the way at which one can resist the argument, each one will involve significant commitments that highlight heretofore unacknowledged connections between justification and content. Even if the internalist is willing to make these moves and resist the argument, the argument reveals a novel way for the epistemic externalist to resist one of internalism’s main arguments. (shrink)

Can it ever be rational to revise one's own logic by one's own lights? In this paper I argue that logic is never rationally revisable, even if one's own logic gives rise to paradoxes and allows one to derive any conclusion whatsoever. Instead of revising logic, we need to revise a certain widely held position in the philosophy of logic, one tied to the standard conception of validity and to the alleged monotonicity of deductive reasoning. I develop the alternative conception (...) of validity and of deductive reasoning, which explains why we are generally entitled to the conclusions of deductive reasoning, even though we rationally do not accept them in certain circumstances tied to paradoxes. (shrink)

I argue that our justification for beliefs about the external physical world need not be constituted by any justified beliefs about perceptual experiences. In this way our justification for beliefs about the physical world may be nondoxastic and this differentiates my proposal from traditional foundationalist theories such as those defended by Laurence BonJour, Richard Fumerton, and Timothy McGrew. On the other hand, it differs from certain non-traditional foundationalist theories such as that defended by James Pryor according to which perceptual experience (...) is sufficient to justify beliefs about the external world. I propose that justification for propositions describing our perceptual experiences partially constitutes any justification we may possess for beliefs concerning the external world. In this way, our justification for beliefs about the physical world may only be inferential since it is grounded in any justification we have for at least one other proposition. This theory occupies an intermediate position between the two aforementioned foundationalist accounts, which allows it to sidestep problems that confront each of them. (shrink)

Knowledge defeat occurs when a subject knows that _p_, gains a defeater for her belief, and thereby loses her knowledge without necessarily losing her belief. It’s far from obvious that externalists can accommodate putative cases of knowledge defeat since a belief that satisfies the externalist conditions for knowledge can satisfy those conditions even if the subject later gains a defeater for her belief. I’ll argue that virtue reliabilists can accommodate defeat intuitions via a new kind of error theory. I argue (...) that in cases where the subject holds dogmatically onto her belief in the face of an apparent defeater, her belief never qualified as knowledge, since the belief was not gained via an exercise of her epistemic virtues. In cases where the subject suspends her judgment upon receiving the putative defeater her original belief might have qualified as knowledge, but crucially, in such cases knowledge is lost due to loss of belief, rather than due to the epistemic force of the defeater. Therefore, knowledge defeat isn’t a genuine phenomenon even though there are no cases where a subject knows what she originally believed after receiving the putative defeater. (shrink)

This dazzlingly original and ambitious book challenges the epistemological and metaphysical preconceptions of contemporary philosophers on many fronts, and prop.

This paper undermines a paradigmatic form of sceptical reasoning. It does this by describing, and then dialectically dissolving, the sceptical-independence presumption, upon which that form of sceptical reasoning relies.

Perception represents colours inexactly. This inexactness results from phenomenally manifest noise, and results in apparent violations of the transitivity of perceptual indiscriminability. Whether these violations are genuine depends on what is meant by 'transitivity of perceptual indiscriminability'.

The aim of this paper is to argue that there is no unproblematic way of delineating perceptual beliefs from non-perceptual beliefs. The concept of perceptual belief is one of the central concepts not only of philosophy of perception but also of epistemology in a broad foundationalist tradition. Philosophers of perception talk about perceptual belief as the interface between perception and cognition and foundationalist epistemologists understand perceptual justification as a relation between perceptual states and perceptual beliefs. We consider three ways of (...) cashing out the difference between perceptual and non-perceptual beliefs (semantic, justificatory, and etiological) and argue that none of them works. Finally, we explore the possibility of understanding perceptual justification without relying on the concept of perceptual beliefs. (shrink)

Amodal completion is the representation of occluded parts of perceived objects. We argue for the following three claims: First, at least some amodal completion-involved experiences can ground knowledge about the occluded portions of perceived objects. Second, at least some instances of amodal completion-grounded knowledge are not sensitive, that is, it is not the case that in the nearest worlds in which the relevant claim is false, that claim is not believed true. Third, at least some instances of amodal completion-grounded knowledge (...) are not safe, that is, it is not the case that in all or nearly all near worlds where the relevant claim is believed true, that claim is in fact true. Thus, certain instances of amodal completion-grounded knowledge refute both the view that knowledge is necessarily sensitive and the view that knowledge is necessarily safe. (shrink)

I clarify and defuse an argument for skepticism about justification with the aid of some results from recent linguistic theory. These considerations illuminate debates about the structure of justification.

In Justification without Awareness (2006), Michael Bergmann presents a dilemma for internalism from which he claims there is “no escape”: The awareness allegedly required for justification is either strong awareness, which involves conceiving of some justification-contributor as relevant to the truth of a belief, or weak awareness, which does not. Bergmann argues that the former leads to an infinite regress of justifiers, while the latter conflicts with the “clearest and most compelling” motivation for endorsing internalism, namely, that for a belief (...) to be justified its truth must not be an accident from the subject’s perspective. Bergmann’s dilemma might initially seem to have the force of a knock-down argument against the classical foundationalist accounts he considers, if not against all forms of internalism. I argue, however, that the weak-awareness horn of Bergmann’s dilemma is unsuccessful. Classical foundationalists can hold on to the main motivation for internalism and avoid a vicious regress of justifiers. (shrink)

Stroud has argued for many years that skepticism is conditionally correct. We cannot, he claims, both undergo a Cartesian-style examination of the extent of our knowledge as well as avoid skepticism. One reason Stroud's position appears quite plausible is the so-called "totality condition" imposed for this kind of examination: as inquiring philosophers we are called upon to assess all of our knowledge, all at once. However, in this paper I argue that Stroud's apparent understanding of the totality condition is mistaken. (...) Evidently, Stroud thinks that honoring the totality condition amounts to imposing the strong requirement that we initially assume that we don't know anything about external reality. However, there is a weaker requirement available: that we initially not assume that we know anything about external reality. I argue i) that the weaker conception of the totality condition is most suitable for the kind of philosophical examination that Stroud seems to have in mind; and ii) that according to this same conception skepticism is not conditionally correct.

In a Jewish context, it seems, it is a naïve consensus view that in praying liturgically one aims to express to God, in the manner of ordinary, interpersonal conversation, those thoughts stated by the text. But on this ordinary conversation model (OCM), a problem of insincerity arises when, as commonly happens, the text states a claim the practitioner does not believe. The idea of redeeming one's prayer by reinterpretation is, I argue, incompatible with OCM. Another strategy, which finds some encouragement (...) in Jewish tradition, is to try inducing the missing belief. I further argue, however, that for one's expression of a belief to be proper, in the sense of being authentic, this belief must be corroborated by the evolving, diachronically largely‐coherent understanding distinctive of one's person—a requirement which an induced, otherwise‐missing belief cannot fulfill. This, I suggest, provides some reason to seek a model of liturgical prayer different from OCM. (shrink)

We can safely infer that a proposition is possible if p is the case. But, I argue, this inference from the actual to the possible is merely explicative in nature, though we employ it at times as if it were ampliative. To make this inference ampliative, we need to include an inference to the best explanation. Specifically, we can draw a substantive conclusion as to whether p is possible from the fact that p is the case, if via our best (...) explanation we can explain how p could occur again in the complete and coherent set of propositions that describes the actual world.

Davidson claims that nothing can count as a reason for a belief except another belief. This claim is challenged by McDowell, who holds that perceptual experiences can count as reasons for beliefs. I argue that McDowell fails to take account of a distinction between two different senses in which something can count as a reason for belief. While a non-doxastic experience can count as a reason for belief in one of the two senses, this is not the sense which is (...) presupposed in Davidson's claim. While I focus on McDowell's view, the argument generalizes to other views which take experiences as reasons for belief. (shrink)

What is the connection between having a phenomenal property and knowing that one has that property? A traditional view on the matter takes the connection to be quite intimate. Whenever one has a phenomenal property, one knows that one does. Recently most authors have denied this traditional view. The goal of this paper is to defend the traditional view. In fact, I will defend something much stronger: I will argue that what it is for a property to be phenomenal is (...) for it to be a property one must know oneself to have when on has it. As we will see, this theory has a number of surprising and welcome upshots, suggesting that the traditional view has been unjustly maligned. (shrink)

I respond to six objections, raised by Selim Berker and Karl Schafer, against the theory offered in my Empiricism and Experience: (1) that the theory needs a problematic notion of subjective character of experience; (2) that the transition from the hypothetical to the categorical fails because of a logical difficulty; (3) that the constraints imposed on admissible views are too weak; (4) that the theory does not deserve the label 'empiricism'; (5) that the motivations provided for the Reliability constraint are (...) insufficient; and (6) that convergence is bound to fail since epistemic entitlements are permissions.

Common-sense philosophers typically maintain that common-sense propositions have a certain kind of epistemic privilege that allows them to evade the threats of skepticism or radical revisionism. Butwhydo they have this special privilege? In response to this question, the “Common-Sense Tradition” contains many different strands of arguments. In this paper, I will develop a strategy that combines two of these strands of arguments. First, the “Dynamic Argument” (or the “starting-point argument”), inspired by Thomas Reid and Charles S. Peirce (but which will (...) be strengthened with the help of Gilbert Harman’s epistemology of belief revision). Second, G.E. Moore’s “greater certainty argument” (interpreted along the lines of Soames’ and Pollock’s construal). This combined strategy, I will argue, is the strong core of Common-Sense Philosophy, and relies on extremely modest and widely held assumptions. (shrink)

Descartes’s Evil Demon argument has been the subject of many reconstructions in recent analytic debates. Some have proposed a reconstruction with a principle of Infallibility, others with a principle of Closure of Knowledge, others with more original principles. In this paper, I propose a new reconstruction, which relies on the combination of two principles, namely the Meta-Coherence principle and the principle of Closure of Justification. I argue that the argument construed in this way is the best interpretation of what is (...) really at play in the Evil Demon intuition, and also that this argument is dialectically much stronger than previous reconstructions. If this is right, then the “Closure plus Meta-Coherence” argument is what anti-sceptics should really be attacking. (shrink)

In this paper I consider the plausibility of developing anti-skepticism by framing the question in linguistic terms: instead of asking whether we know, we ask what falls within the extension of the word “know”. I first trace two previous attempts to develop anti-skepticism in this way, from Austin (particularly as presented by Kaplan) and from epistemic contextualism, and I present reasons to think that both approaches are unsuccessful. I then focus on a more recently popular attempt to develop anti-skepticism from (...) the “function-first” approach associated with Craig, which I also show to be problematic. I then argue that the apparent prima facie plausibility of fighting skepticism on linguistic grounds is due to a methodological spill-over from linguistics. Once we recognize this, it becomes clear that debate around skepticism should not be conducted in linguistic terms. (shrink)

In this paper we don’t intend to show, against the sceptic, that most of our everyday beliefs about the external world are cases of knowledge. What we do try to show is that it is more rational to hold that most of such beliefs are actually cases of knowledge than to deny them this status, as the external world sceptic does. In some sense, our point of view is the opposite of Hume’s, who held that reason clearly favours scepticism about (...) the independent existence of an external world rather than common sense belief in such an independent existence. In arguing for the superior rationality of this common sense, Moorean view, we also take a fallibilist conception of knowledge to be rationally preferable to an infallibilist view of it. (shrink)

Epistemologists and philosophers of mind both ask questions about belief. Epistemologists ask normative questions about belief—which beliefs ought we to have? Philosophers of mind ask metaphysical questions about belief—what are beliefs, and what does it take to have them? While these issues might seem independent of one another, there is potential for an interesting sort of conflict: the epistemologist might think we ought to have beliefs that, according to the philosopher of mind, it is impossible to have. This essay argues (...) that this conflict does arise and that it creates problems for traditional skeptical views in epistemology. In particular, it argues that on certain popular views about the nature of belief, it is impossible to adopt the near-global agnosticism recommended by the skeptical epistemologist. On other plausible views, it is possible only in special circumstances, and this limitation undermines skeptical epistemological claims. The only views about the nature of belief on which there are no metaphysical hurdles to adopting the agnosticism recommended by the skeptic are views that face powerful objections—objections that are completely independent of antiskeptical epistemological considerations.

Jessica Brown argues against infallibilist views of knowledge as follows. (1) Infallibilism is committed to the sufficiency of knowledge for self-support: if one knows that p, then p is part of one's evidence for p. (2) This commitment is false: often one knows that p, but p isn't part of one's evidence for p. So (3) infallibilism about knowledge is false. I’ll respond by questioning the motivation for (2). Brown’s main line of argument in defense of (2) concerns the awkwardness (...) of citing a proposition as evidence in support of itself. I’ll argue that this infelicity, while genuine, stem not from any particular view about knowledge, but from a probabilistic conception of evidential support. Given such a conception of evidential support, whenever E is part of someone’s evidence, E is evidence for E. This is no less awkward for the fallibilist than the infallibilist. I’ll argue that if we adopt a contextualist view of evidence, we can hold on to the independently attractive probabilistic conception of evidential support, while respecting the idea that there's something wrong with citing a proposition as evidence for itself. -/- .

Recent literature in epistemology has focused on the following argument for skepticism (SA): I know that I have two hands only if I know that I am not a handless brain in a vat. But I don't know I am not a handless brain in a vat. Therefore, I don't know that I have two hands. Part I of this article reviews two responses to skepticism that emerged in the 1980s and 1990s: sensitivity theories and attributor contextualism. Part II considers (...) the more recent ‘neo-Moorean’ response to skepticism and its development in ‘safety’ theories of knowledge. Part III argues that the skeptical argument set out in SA is not of central importance. Specifically, SA is parasitic on skeptical reasoning that is more powerful and more fundamental than that displayed by SA itself. Finally, Part IV reviews a Pyrrhonian argument for skepticism that is not well captured by SA, and considers a promising strategy for responding to it. (shrink)

Epistemologists who have studied disagreement have started to devote attention to the notion of epistemic standing. One feature of epistemic standing they have not drawn attention to is a distinction between what I call “broad” and “narrow” epistemic standing. Someone who is, say, your broad epistemic peer with respect to some topic is someone who is generally as familiar with and good at handling the evidence as you are. But someone who is your narrow epistemic peer with respect to that (...) topic is someone who is familiar with the evidence and as good at handling it as you are on that particular occasion. Thus, it’s possible for you to be my broad peer while also being my narrow inferior or superior. Attending to this distinction elicits different intuitions about some of the well-known cases in the epistemology of disagreement. Focusing on broad epistemic standing, which epistemologists have done, tends to yield conciliationist responses. But focusing on narrow epistemic standing, which epistemologists have not done, yields steadfast responses. The reason for this difference has to do with how we figure out someone’s broad or narrow epistemic standing: to determine her broad epistemic standing, you need to look at her epistemic traits and her familiarity with the evidence rather than to examine the evidence she gives. But to determine her narrow epistemic standing, you have to focus on her disclosed evidence rather than her epistemic traits or familiarity with the evidence. (shrink)

We review the "Entitlement" projects of Tyler Burge and Crispin Wright in light of recent work from and surrounding both philosophers. Our review dispels three misunderstandings. First, Burge and Wright are not involved in a common “entitlement” project. Second, though for both Wright and Burge entitlement is the new notion, “entitlement” is not some altogether third topic not clearly connected to the nature of knowledge or the encounter with skepticism. Third, entitlement vs. justification does not align with the externalism vs. (...) internalism distinction. (shrink)

What is the best account of process reliabilism about epistemic justification, especially epistemic entitlement? I argue that entitlement consists in the normal functioning (proper operation) of the belief-forming process when the process has forming true beliefs reliably as an etiological function. Etiological functions involve consequence explanation: a belief-forming process has forming true beliefs reliably as a function just in case forming-true beliefs reliably partly explains the persistence of the process. This account paves the way for avoiding standard objections to process (...) reliabilism and situations epistemic entitlement within a normative framework of functions and functional norms. (shrink)

We offer a general framework for theorizing about the structure of knowledge and belief in terms of the comparative normality of situations compatible with one’s evidence. The guiding idea is that, if a possibility is sufficiently less normal than one’s actual situation, then one can know that that possibility does not obtain. This explains how people can have inductive knowledge that goes beyond what is strictly entailed by their evidence. We motivate the framework by showing how it illuminates knowledge about (...) the future, knowledge of lawful regularities, knowledge about parameters measured using imperfect instruments, the connection between knowledge, belief, and probability, and the dynamics of knowledge and belief in response to new evidence.

In this paper I defend the claim that testimony can serve as a basic source of knowledge of other people’s mental lives against the objection that testimonial knowledge presupposes knowledge of other people’s mental lives and therefore can’t be used to explain it.

According to intentionalism, perceptual experience is a mental state with representational content. When it comes to the epistemology of perception, it is only natural for the intentionalist to hold that the justificatory role of experience is at least in part a function of its content. In this paper, I argue that standard versions of intentionalism trying to hold on to this natural principle face what I call the “defeasibility problem”. This problem arises from the combination of standard intentionalism with further (...) plausible principles governing the epistemology of perception: that experience provides defeasible justification for empirical belief, and that such justification is best construed as probabilification. After exploring some ways in which the standard intentionalist could deal with the defeasibility problem, I argue that the best option is to replace standard intentionalism by what I call “phenomenal intentionalism”. Where standard intentionalism construes experiences as of p as having the content p, phenomenal intentionalism construes experiences as of p as having “phenomenal” or “looks contents”: contents of the form Lp.

Today, many philosophers think that perceptual experiences are conscious mental states with representational content and phenomenal character. Subscribers to this view often go on to construe experience more precisely as a propositional attitude sui generis ascribing sensible properties to ordinary material objects. I argue that experience is better construed as a kind of belief ascribing 'phenomenal' properties to such objects. A belief theory of this kind deals as well with the traditional arguments against doxastic accounts as the sui generis view. (...) Moreover, in contrast to sui generis views, it can quite easily account for the rational or reason providing role of experience. (shrink)

How should we understand the epistemic role of perception? According to epistemological disjunctivism (ED), a subject’s perceptual knowledge that p is to be explained in terms of the subject believing that p for a factive and reflectively accessible reason. I argue that ED raises far-reaching questions for rationality and deliberation; I illustrate those questions by setting up a puzzle about belief-suspension, and I argue that ED does not have the resources to make sense of the rationality of belief-suspension in cases (...) in which suspending is clearly rational. The conclusion that I draw from the puzzle is mainly negative: the epistemic contribution of perception cannot be explained in terms of a warrant-conferring relation between perception and belief. However, toward the end, I sketch a positive picture of the epistemic role of perception in terms of a direct explanatory relation between perception and knowledge. (shrink)

The phenomenon of cognitive penetration has received a lot of attention in recent epistemology, as it seems to make perceptual justification too easy to come by for experientialist theories of justification. Some have tried to respond to this challenge by arguing that cognitive penetration downgrades the epistemic status of perceptual experience, thereby diminishing its justificatory power. I discuss two examples of this strategy, and argue that they fail on several grounds. Most importantly, they fail to realize that cognitive penetration is (...) just an instance of a larger problem for experientialist theories of perceptual justification. The challenge does not lie in explaining how cognitive penetration is able to downgrade the epistemic status of perceptual experience, the challenge lies in explaining why perceptual experience would have a special epistemic status to begin with. To answer this challenge, experientialists have to solve the distinctiveness problem: they have to explain what is so distinctive about perceptual experience that enables it to provide evidential justification without being in need of justification itself. Unfortunately, an internalist answer to this problem does not appear to be forthcoming, even though it would certainly help with explaining the problem of cognitive penetration. (shrink)

Predictive processing accounts of perception assume that perception does not work in a purely bottom-up fashion but also uses acquired knowledge to make top-down predictions about the incoming sensory signals. This provides a challenge for foundationalist accounts of perception according to which perceptual beliefs are epistemically basic, that is, epistemically independent from other beliefs. If prior beliefs rationally influence which perceptual beliefs we come to accept, then foundationalism about perception appears untenable. I review several ways in which foundationalism might be (...) reconciled with PP from both an internalist and externalist perspective, and argue that an externalist foundationalism provides the best match with PP. (shrink)

Perceptual Dogmatism holds that if it perceptually seems to S that p, then S has immediate prima facie justification for the belief that p. Various philosophers have made the notion of a perceptual seeming more precise by distinguishing perceptual seemings from both sensations and beliefs to accommodate a) the epistemic difference between perceptual judgments of novices and experts, and, b) the problem of the speckled hen. Using somewhat different terminology, perceptual seemings are supposed to be high-level percepts instead of low-level (...) sensations. I argue that although it is right that perceptual seemings should not be identified with sensations, they should also not be identified with percepts. There is no strong reason to assume that sensations and percepts exist as separate conscious states, and it appears therefore best to identify perceptual seemings simply with perceptual experiences interpreted as entities incorporating aspects from both sensations and percepts. However, even with this plausible identification in hand, the speckled hen will remain problematic for PD. (shrink)

In this paper, I consider how a general epistemic norm of action that I have proposed in earlier work should be specified in order to govern certain types of acts: assertive speech acts. More specifically, I argue that the epistemic norm of assertion is structurally similar to the epistemic norm of action. First, I argue that the notion of warrant operative in the epistemic norm of a central type of assertion is an internalist one that I call ‘discursive justification.’ This (...) type of warrant is internalist insofar as it requires that the agent is capable of articulating reasons for her belief. The idea, roughly, is that when one asserts that p, one is supposed to be in a position to give reasons for believing that p. Bonjour’s reliable clairvoyant Norman, for example, is not in an epistemic position to make assertions regarding the president’s whereabouts—even if Norman knows the president’s whereabouts. In conclusion, I briefly consider whether a type of skeptical argument—often labeled Agrippa’s Trilemma—is motivated, at least in part, by the fact that responses to it violate the relevant epistemic norm of assertion.
