In this paper, I argue that what underlies internalism about justification is a rationalist conception of justification, not a deontological conception of justification, and I argue for the plausibility of this rationalist conception of justification. The rationalist conception of justification is the view that a justified belief is a belief that is held in a rational way; since we exercise our rationality through conscious deliberation, the rationalist conception holds that a belief is justified iff a relevant possible instance of conscious (...) deliberation would endorse the belief. The importance of conscious deliberation stems from its role in guiding us in acquiring true beliefs: whereas the externalist holds that if we wish to acquire true beliefs, we have to begin by assuming that some of our usual methods of belief formation generally provide us with true beliefs, the intemalist holds that if we form beliefs by conscious deliberation, we can be conscious of reasons for thinking that our beliefs are true. Conscious deliberation can make us conscious of reasons because it proceeds via rational intuitions. I argue that despite the fallibility of rational intuition, rational intuitions do enable us to become conscious of reasons for belief. (shrink)

There is a widely accepted family of views in the epistemology of testimony centering around the claim that belief is the central item involved in a testimonial exchange. For instance, in describing the process of learning via testimony, Elizabeth Fricker provides the following: “one language-user has a belief, which gives rise to an utterance by him; as a result of observing this utterance another user of the same language, his audience, comes to share that belief.” In a similar spirit, Alvin (...) Plantinga says that “…a belief on the part of the testifiee has warrant only if that belief has warrant for the testifier.” In both of these passages, we find strands of what I shall call the Belief View of Testimony.

Revisionary ontologies seem to go against our common sense convictions about which material objects exist. These views face the so-called Problem of Reasonableness: they have to explain why reasonable people don’t seem to accept the true ontology. Most approaches to this problem treat the mismatch between the ontological truth and ordinary belief as superficial or not even real. By contrast, I propose what I call the “uncompromising solution”. First, I argue that our beliefs about material objects were influenced by evolutionary (...) forces that were independent of the ontological truth. Second, I draw an analogy between the Problem of Reasonableness and the New Evil Demon Problem and argue that the revisionary ontologist can always find a positive epistemic status to characterize ordinary people’s beliefs about material objects. Finally, I address the worry that the evolutionary component of my story also threatens to undermine the best arguments for revisionary ontologies. (shrink)

This paper proposes a new externalist account of defeaters, in terms of reliable indicators, as an integral part of a unified externalist account of warrant and defeat. It is argued that posing externalist conditions on warrant, but internalist conditions on defeat lead to undesirable tensions. The proposal is contrasted to some rival accounts and then tested on some widely discussed cases, like the airport case. Misleading defeaters, where Laurence BonJour’s reliable clairvoyants serve as examples, also receive treatment, partly because they (...) illustrate how internalist constraints are inserted into the set up of the problem and therefore unduly constrain the domain of satisfactory solutions. Lastly, the proposal is defended against some objections. Firstly, that by posing externalist conditions on defeat, the account becomes too open. Secondly, that an externalist account fails to take into account the epistemic assessments of our fellows in the epistemic practice of forming beliefs and making epistemic claims, which can be based on accessible warrant only.

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)

Selim Berker argues that epistemic consequentialism is pervasive in epistemology and that epistemic consequentialism is structurally flawed. is incorrect, however. I distinguish between epistemic consequentialism and epistemic instrumentalism and argue that most putative consequentialists should be considered instrumentalists. I also identify the structural problem of epistemic consequentialism Berker attempts to pinpoint and show that epistemic instrumentalism does not have the consequentialist problem.

In “Compassionate Phenomenal Conservatism” (2007), “Phenomenal Conservatism and the Internalist Intuition” (2006), and Skepticism and the Veil of Perception (2001), Michael Huemer endorses the principle of phenomenal conservatism, according to which appearances or seemings constitute a fundamental source of (defeasible) justification for belief. He claims that those who deny phenomenal conservatism, including classical foundationalists, are in a self-defeating position, for their views cannot be both true and justified; that classical foundationalists have difficulty accommodating false introspective beliefs; and that phenomenal conservatism (...) is most faithful to the central internalist intuition. I argue that Huemer’s self-defeat argument fails, that classical foundationalism is able to accommodate fallible introspective beliefs, and that classical foundationalism captures a relatively clear internalist intuition. I also show that the motivation for phenomenal conservatism is less than clear. (shrink)

In this article, I argue that access internalism should replace preservationism, which has been called “a received view” in the epistemology of memory, as the standard position about memorial justification. My strategy for doing so is two-pronged. First, I argue that the considerations which motivate preservationism also support access internalism. Preservationism is mainly motivated by its ability to answer the explanatory challenges posed by the problem of stored belief and the problem of forgotten evidence. However, as I will demonstrate, access (...) internalism also has the resources to provide plausible solutions to those problems. Second, I argue that preservationism faces a couple of problems which access internalism avoids. Doing so, I present a new scenario which, on the one hand, functions as a counterexample to preservationism, and, on the other hand, provides intuitive support for access internalism. Moreover, I also demonstrate how preservationism, in light of recent research in cognitive psychology, is vulnerable to skepticism about memorial justification, whereas access internalism remains unthreatened.

The question of whether knowledge is definable in terms of belief, which has played an important role in epistemology for the last 50 years, is studied here in the framework of epistemic and doxastic logics. Three notions of definability are considered: explicit definability, implicit definability, and reducibility, where explicit definability is equivalent to the combination of implicit definability and reducibility. It is shown that if knowledge satisfies any set of axioms contained in S5, then it cannot be explicitly defined in (...) terms of belief. S5 knowledge can be implicitly defined by belief, but not reduced to it. On the other hand, S4.4 knowledge and weaker notions of knowledge cannot be implicitly defined by belief, but can be reduced to it by defining knowledge as true belief. It is also shown that S5 knowledge cannot be reduced to belief and justification, provided that there are no axioms that involve both belief and justification. (shrink)

Over the last several years a number of leading philosophers – including Catherine Elgin, Linda Zagzebski, Jonathan Kvanvig, and Duncan Pritchard – have grown increasingly dissatisfied with the contemporary focus on knowledge in epistemology and have attempted to “recover” the notion of understanding. According to some of these philosophers, in fact, understanding deserves not just to be recovered, but to supplant knowledge as the focus of epistemological inquiry. This entry considers some of the main reasons why philosophers have taken understanding (...) to be more valuable than knowledge, focusing on claims that it is more transparent, that it better reflects or mirrors the world, and that it is a greater intellectual achievement. (shrink)

A number of contemporary philosophers endorse a Pyrrhonian theme: that one has knowledge only if one knows or understands that one’s beliefs are reliably formed. Otherwise, one is like a man who grasps gold in the dark: such a man is successful, but his success is a matter of luck, and so not creditable to him. It is argued that the skeptical problem and the problem of moral luck share a common structure and a common solution. Specifically, a virtue-theoretic approach (...) helps us to understand important relations among luck, success and credit for success. It is argued that knowledge is an instance of success through virtue, and that, in general, success through virtue is creditable to the virtuous agent. (shrink)

The prequel to this paper introduced the topic of iteration principles in epistemology and surveyed some arguments in support of them. In this sequel, I'll consider two influential families of objection to iteration principles. The first turns on the idea that they lead to some variety of skepticism, and the second turns on ‘margin for error’ considerations adduced by Timothy Williamson.

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)

Many people agree that a proper epistemological treatment of testimonial knowledge will regard testimonial warrant—the total truth-conducive support enjoyed by a belief grounded on a piece of testimony —as socially diffuse, in the sense that it is not something that supervenes on the proper functionality of the hearer’s cognitive resources together with the reasons she has for accepting the testimony. After arguing for such a view, I go on to identify a challenge many people think flows from an acknowledgment of (...) the social diffusion of warrant. In particular, such an acknowledgment appears to preclude a happy account of the rationality of testimony-based belief. After identifying the nature of this challenge and the various positions that one can take on it, I develop a response according to which rationality itself (like warrant) is socially diffuse.

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)

For some years now, Michael Bergmann has urged a dilemma against internalist theories of epistemic justification. For reasons I explain below, some epistemologists have thought that Michael Huemer’s principle of Phenomenal Conservatism can split the horns of Bergmann’s dilemma. Bergmann has recently argued, however, that PC must inevitably, like all other internalist views, fall prey to his dilemma. In this paper, I explain the nature of Bergmann’s dilemma and his reasons for thinking that PC cannot escape it before arguing that (...) he is mistaken: PC can indeed split its horns. (shrink)

In this paper, I defend the view that we can have perceptual moral knowledge. First, I motivate the moral perception view by drawing on some examples involving perceptual knowledge of complex non‐moral properties. I argue that we have little reason to think that perception of moral properties couldn't operate in much the same way that our perception of these complex non‐moral properties operates. I then defend the moral perception view from two challenging objections that have yet to be adequately addressed. (...) The first objection is that the moral perception view has implausible commitments concerning the morally blind, people who would claim not to perceive wrongness. The second objection is that the moral perception view is not really compatible with a wide range of the main candidate moral theories. I argue that the moral empiricist has plausible responses to both of these objections. I then address three residual concerns that my defense raises. (shrink)

Our aim is to provide a topography of the relevant philosophical terrain with regard to the possible ways in which knowledge can be conceived of as extended. We begin by charting the different types of internalist and externalist proposals within epistemology, and we critically examine the different formulations of the epistemic internalism/externalism debate they lead to. Next, we turn to the internalism/externalism distinction within philosophy of mind and cognitive science. In light of the above dividing lines, we then examine first (...) the extent to which content externalism is compatible with epistemic externalism; second, whether active externalism entails epistemic externalism; and third whether there are varieties of epistemic externalism that are better suited to accommodate active externalism. Finally, we examine whether the combination of epistemic and cognitive externalism is necessary for epistemology and we comment on the potential ramifications of this move for social epistemology and philosophy of science.

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)

What is the nature of the evidence provided by thought experiments in philosophy? For instance, what evidence is provided by the Gettier thought experiment against the JTB theory of knowledge? According to one view, it provides as evidence only a certain psychological proposition, e.g. that it seems to one that the subject in the Gettier case lacks knowledge. On an alternative, nonpsychological view, the Gettier thought experiment provides as evidence the nonpsychological proposition that the subject in the Gettier case lacks (...) knowledge (e.g., Williamson 2007). Given the centrality of thought experiments to philosophical enquiry, the correct account of thought experiment evidence is important for understanding the nature of philosophical methodology. Further, Williamson argues that a misguided adherence to the psychological view of thought experiment evidence encourages scepticism about philosophy since it opens a gap between our evidence and the nonpsychological subject matter of philosophy. The main aim of this paper is to defend the psychological view against recent objections. In particular, I argue that even if thought experiment evidence is psychological, it can still provide justification for non-psychological claims which are the subject matter of philosophy. (shrink)

This paper responds to Sven Bernecker’s argument that agent reliabilism cannot accommodate internalist intuitions about clarvoyance cases. In section 1 we clarify a version of agent reliabilism and Bernecker’s objections against it. In section 2 we say more about how the notion of cognitive integration helps to adjudicate clairvoyance cases and other proposed counterexamples to reliabilism. The central idea is that cognitive integration underwrites a kind of belief ownership, which in turn underwrites the sort of responsibility for belief required for (...) subjective justification. In section 3 we say more about what cognitive integration amounts to, drawing on some recent accounts of desire ownership from the literature on autonomy and moral responsibility. (shrink)

A quasi-sequel to "Epistemic Teleology and the Separateness of Propositions." Covers some of the same ground, but also extends the basic argument in an important way.

Abductivists claim that explanatory considerations (e.g., simplicity, parsimony, explanatory breadth, etc.) favor belief in the external world over skeptical hypotheses involving evil demons and brains in vats. After showing how most versions of abductivism succumb fairly easily to obvious and fatal objections, I explain how rationalist versions of abductivism can avoid these difficulties. I then discuss the most pressing challenges facing abductivist appeals to the a priori and offer suggestions on how to overcome them.

I reconstruct and critique two arguments Laurence BonJour has recently offered against skepticism about the a priori. While the arguments may provide anti-skeptical, internalist foundationalists with reason to accept the a priori, I show that neither argument provides sufficient reason for believing the more general conclusion that there is no rational alternative to accepting the a priori.

The abductivist reply to skepticism is the view that commonsense explanations of the patterns and regularities that appear in our sensory experiences should be rationally preferred to skeptical explanations of those same patterns and regularities on the basis of explanatory considerations. In this article I critically examine Laurence BonJour’s rationalist version of the abductivist position. After explaining why BonJour’s account is more defensible than other versions of the view, I argue that the notion of probability he relies upon is deeply (...) problematic, that he incorporates an implausible double-standard concerning a priori and a posteriori justification, and that his view is vulnerable to skepticism about the a priori. I suggest that some of these problems are due to idiosyncratic commitments BonJour makes and that abductivists would be better off without them. I conclude with some suggestions about how to improve BonJour’s abductivist response to skepticism. (shrink)

This article provides a brief overview of several formal frameworks concerning the relation between knowledge on the one hand, and obligation on the other. We discuss the paradox of the knower, knowledge based obligation, knowingly doing, deontic dynamic epistemology, descriptive obligations, and responsibilities as dynamic epistemology.

Evidentialists maintain that epistemic justification is strictly a function of the evidence one has at the moment of belief. I argue here, on the basis of two kinds of cases, that the possession of good evidence is an insuflicient basis for justification. I go on to propose a modification of evidentialism according to which justification sometimes requires intellectually virtuous agency. The discussion thereby underscores an important point of contact between evidentialism and the more recent enterprise of virtue epistemology.

The problem of skepticism is often understood as a paradox: a valid argument with plausible premises whose conclusion is that we lack justification for perceptual beliefs. Typically, this conclusion is deemed unacceptable, so a theory is offered that posits conditions for justification on which some premise is false. The theory defended here is more general, and explains why the paradox arises in the first place. Like Strawson’s (Introduction to logical theory, Wiley, New York, 1952) “ordinary language” approach to induction, the (...) theory posits something built into the very notion of justification: it is loaded with a bias towards the proposition that we are not massively deceived. Beyond the paradox, remaining skeptical problems consist of metaphysical and practical questions: whether we are massively deceived, or why we should use our loaded notion rather than some other. Such challenges have profound epistemological significance, but they are not problems that an a priori theory of justification can solve. (shrink)

Truth monism is the idea that only true beliefs are of fundamental epistemic value. The present paper considers three objections to truth monism, and argues that, while the truth monist has plausible responses to the first two objections, the third objection suggests that truth monism should be reformulated. On this reformulation, which we refer to as accuracy monism, the fundamental epistemic goal is accuracy, where accuracy is a matter of “getting it right.” The idea then developed is that accuracy is (...) a genus with several species. Believing truly is a prominent species, but it is not the only one. Finally, it is argued that accuracy monism is equally good or better than both traditional truth monism and its main dialectical rival, value pluralism, when it comes to satisfying three important axiological desiderata.

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? (...) Understood more broadly, epistemology is about issues having to do with the creation and dissemination of knowledge in particular areas of inquiry. This article will provide a systematic overview of the problems that the questions above raise and focus in some depth on issues relating to the structure and the limits of knowledge and justification.

The recursive aspect of process reliabilism has rarely been examined. The regress puzzle, which illustrates infinite regress arising from the combination of the recursive structure and the no-defeater condition incorporated into it, is a valuable exception. However, this puzzle can be dealt with in the framework of process reliabilism by reconsidering the relationship between the recursion and the no-defeater condition based on the distinction between prima facie and ultima facie justification. Thus, the regress puzzle is not a basis for abandoning (...) process reliabilism. A genuinely intractable problem for recursive reliabilism lies in the gap between the reliability of the entire path to a belief and that of its parts. Confronted with this puzzle, reliabilists can orient themselves toward ‘reliable-as-a-whole reliabilism’ instead of ‘reliable-in-every-part reliabilism’, including recursive reliabilism, which is found to be not well-motivated.

Contemporary virtue epistemology (hereafter ‘VE’) is a diverse collection of approaches to epistemology. At least two central tendencies are discernible among the approaches. First, they view epistemology as a normative discipline. Second, they view intellectual agents and communities as the primary focus of epistemic evaluation, with a focus on the intellectual virtues and vices embodied in and expressed by these agents and communities. -/- This entry introduces many of the most important results of the contemporary VE research program. These include (...) novel attempts to resolve longstanding disputes, solve perennial problems, grapple with novel challenges, and expand epistemology’s horizons. In the process, it reveals the diversity within VE. Beyond sharing the two unifying commitments mentioned above, its practitioners diverge over the nature of intellectual virtues, which questions to ask, and which methods to use. -/- It will be helpful to note some terminology before proceeding. First, we use ‘cognitive’, ‘epistemic’ and ‘intellectual’ synonymously. Second, we often use ‘normative’ broadly to include not only norms and rules, but also duties and values. Finally, ‘practitioners’ names contemporary virtue epistemologists. (shrink)
