This paper aims at resolving a puzzle about the persuasiveness of bootstrapping. On the one hand, bootstrapping is not a persuasive method of settling questions about the reliability of a source. On the other hand, our beliefs that our sense apparatus is reliable is based on other empirically formed beliefs, that is, they are acquired via a presumably complex bootstrapping process. I will argue that when we doubt the reliability of a source, bootstrapping is not a persuasive method for coming (...) to believe that the source is reliable. However, when being initially unaware of a source and its reliability, as in the case of forming beliefs about our sense apparatus, bootstrapping can be eventually persuasive. (shrink)

Offering a solution to the skeptical puzzle is a central aim of Nozick's sensitivity account of knowledge. It is well-known that this account faces serious problems. However, because of its simplicity and its explanatory power, the sensitivity principle has remained attractive and has been subject to numerous modifications, leading to a of sensitivity accounts. I will object to these accounts, arguing that sensitivity accounts of knowledge face two problems. First, they deliver a far too heterogeneous picture of higher-level beliefs about (...) the truth or falsity of one's own beliefs. Second, this problem carries over to bootstrapping and Moorean reasoning. Some beliefs formed via bootstrapping or Moorean reasoning are insensitive, but some closely related beliefs in even stronger propositions are sensitive. These heterogeneous results regarding sensitivity do not fit with our intuitions about bootstrapping and Moorean reasoning. Thus, neither Nozick's sensitivity account of knowledge nor any of its modified versions can provide the basis for an argument that bootstrapping and Moorean reasoning are flawed or for an explanation why they seem to be flawed.

In this paper, I defend the heterogeneity problem for sensitivity accounts of knowledge against an objection that has been recently proposed by Wallbridge in Philosophia. I argue in, 479–496, 2015) that sensitivity accounts of knowledge face a heterogeneity problem when it comes to higher-level knowledge about the truth of one’s own beliefs. Beliefs in weaker higher-level propositions are insensitive, but beliefs in stronger higher-level propositions are sensitive. The resulting picture that we can know the stronger propositions without being in a (...) position to know the weaker propositions is too heterogeneous to be plausible. Wallbridge objects that there is no heterogeneity problem because beliefs in the weaker higher-level propositions are also sensitive. I argue against Wallbridge that the heterogeneity problem is not solved but only displaced. Only some beliefs in the weaker higher-level propositions are sensitive. I conclude that the heterogeneity problem is one of a family of instability problems that sensitivity accounts of knowledge face and that Wallbridge’s account raises a further problem of this kind.

I will compare Lehrer’s anti-skeptical strategy from a coherentist point of view with the anti-skeptical strategy of the Mooreans. I will argue that there are strong similarities between them: neither can present a persuasive argument to the skeptic and both face the problem of easy knowledge in one way or another. However, both can offer a complete and self-explanatory explanation of knowledge although Mooreanism can offer the more natural one. Hence, one has good reasons to prefer Mooreanism to Lehrer’s anti-skeptical (...) approach, if one does not prefer coherentism to foundationalism for other reasons. (shrink)

This paper provides a reinterpretation of some of the most influential skeptical arguments, Agrippa’s trilemma, meta-regress arguments, and Cartesian external world skepticism. These skeptical arguments are reasonably regarded as unsound arguments about the extent of our knowledge. However, reinterpretations of these arguments tell us something significant about the preconditions and limits of persuasive argumentation. These results contribute to the ongoing debates about the nature and resolvability of deep disagreement. The variety of skeptical arguments shows that we must distinguish different types (...) of deep disagreement. Moreover, the reinterpretation of skeptical arguments elucidates that deep disagreement cannot be resolved via argumentation. (shrink)

This paper replies to the comments made in Acta Analytica by Peter Baumann, Kelly Becker, Marian David, Nenad Miščević, Wes Siscoe, and Danilo Šuster on my Knowing and Checking: An Epistemological Investigation (Routledge 2019), hereinafter abbreviated as KC. These papers resulted from a workshop organized by the department of philosophy of the University of Maribor. I am very thankful to the organizers of the workshop and to the authors for their comments.

In this Précis, I provide an overview of my Monograph Knowing and Checking: An Epistemological Investigation (Melchior 2019), which is subject to a book symposium organized by the University of Maribor. This volume in Acta Analytica contains contributions by Peter Baumann, Kelly Becker, Marian David, Nenad Miščević, Robert Weston Siscoe, and Danilo Šuster along with my replies.

This article aims to provide a structural analysis of the problems related to the easy knowledge problem. The easy knowledge problem is well known. If we accept that we can have basic knowledge via a source without having any prior knowledge about the reliability or accuracy of this source, then we can acquire knowledge about the reliability or accuracy of this source too easily via information delivered by the source. Rejecting any kind of basic knowledge, however, leads into an infinite (...) regress and, plausibly, to skepticism. The article argues that the third alternative, accepting basic knowledge but rejecting easy knowledge, entails closure failure. This is obviously the case for deductive bootstrapping, but, notably, the problem also arises for inductive bootstrapping. Hence, the set of problems related to the easy knowledge problem has the structure of a trilemma. We are forced to accept easy knowledge, closure failure, or skepticism. (shrink)

That bootstrapping and Moorean reasoning fail to instantiate persuasive argumentation is an often informally presented but not systematically developed view. In this paper, I will argue that this unpersuasiveness is not determined by principles of justification transmission but by two straightforward principles of rationality, understood as a concept of internal coherence. First, it is rational for S to believe the conclusion of an argument because of the argument, only if S believes sufficiently many premises of the argument. Second, if S (...) doubts that a source O is reliable and believes that information i is delivered by O, then S rationally suspends judgment about the truth of i. This paper aims to accomplish two tasks. First, it provides a thorough analysis of why bootstrapping argumentation is not an instance of rational persuasion. Second, it contains a more general theory about preconditions and limits of persuasive argumentation. (shrink)

This paper investigates some metaphysical and epistemological assumptions behind Bogen and Woodward’s data-to-phenomena inferences. I raise a series of points and suggest an alternative possible Kantian stance about data-to-phenomena inferences. I clarify the nature of the suggested Kantian stance by contrasting it with McAllister’s view about phenomena as patterns in data sets.

Suppose Ted is in an ordinary house in good viewing conditions and believes red, his table is red, entirely because he sees his table and its color; he also believes not-white, it is false that his table is white and illuminated by a red light, because not-white is entailed by red. The following three claims about this table case clash, but each seems plausible: 1. Ted’s epistemic position is strong enough for him to know red. 2. Ted cannot know not-white (...) on the basis of red. 3. The epistemic closure principle, suitably restricted, is true. Stewart Cohen has called this three-way clash of intuitions the problem of easy knowledge. If we wish to resolve the clash without accepting skepticism, we seem to have two options. According to the hard argument, the best response is to reject 3. The easy argument rejects 2. But there may be a third alternative, the reverse argument, which rejects 1 without ceding a substantial amount of ground to the skeptic. In this essay I criticize recent versions of the reverse argument and the hard argument, thereby lending support to the easy argument. (shrink)

Closure principles loom large in recent internalist critiques of epistemic externalism. Cohen (Philos Phenomenol Res 65:309–329, 2002, Philos Phenomenol Res 70:417–430, 2005), Vogel (J Philos 97:602–623, 2000), and Fumerton (Meta-Epistemology and skepticism. Rowman and Littlefield, Lanham, 1995) argue that, given closure, epistemic externalism is committed to the possibility of implausibly easy knowledge. By contrast, Zalabardo (Philos Rev 114:33–61, 2005) proposes that epistemic closure actually precludes the possibility of easy knowledge, and appeals to closure principles to solve the problem of easy (...) knowledge. In my view, disagreement over closure’s bearing on externalism and the problem of easy knowledge is rooted in a failure to bear in mind the familiar distinction between ex ante and ex post forms of epistemic justification and warrant. When this distinction is kept in focus, the result is clear: epistemic closure provides no relief from the problem of easy knowledge. (shrink)

Abstract: Ernest Sosa has done important work on epistemic circularity, epistemic virtue, and reflective knowledge. He holds that epistemic circularity need not be vicious and need not prevent us from knowing that our ways of forming beliefs are reliable. In this article, I briefly explore Sosa's defense of this view and raise some questions about what is required for reflective knowledge.

El objetivo central de este trabajo consiste en articular la noción de cooperación epistémica con la de fiabilidad, ofreciendo una alternativa al intelectualismo. La tesis principal radica en que la fiabilidad de los procesos epistémicos se conforman a partir de que los sujetos cooperan unos con otros en la atribución de conocimiento. De esta manera la cooperación epistémica se vincula con varias posiciones teóricas: con el contextualismo, al constituir un contexto flexible o exigente para la aceptación de proposiciones; con una (...) respuesta al escepticismo, pues el escéptico permanece aislado del contexto de enunciación, con el inductivismo y la circularidad, pues mediante la cooperación epistémica se determina en qué contextos el inductivismo y la circularidad son argumentos legítimos.

I develop one partial explanation of the origins of our fallibilist intuitions about knowledge in ordinary language fallibilism and argue that this explanation indicates that our epistemic methodology should be more impartial and theory-neutral. First, I explain why the so-called Moorean constraint (cf. Hawthorne 2005, 111) that encapsulates fallibilist intuitions is fallibilism’s cornerstone. Second, I describe a pattern of fallibilist reasoning in light of the influential dual processing and heuristics and biases approach to cognition (cf. Kahneman 2011; Thaler and Sunstein (...) 2008; Evans 2017). I suggest that this pattern of reasoning involves the question-substitution heuristic, the availability and representativeness heuristics, the focusing bias as well as framing effects, priming and the anchoring and adjusting heuristic. Third, I argue that this fallibilist pattern of reasoning is methodologically dubious because it involves a vicious circularity and briefly outline an alternative, more impartial and theory-neutral abductive methodology for the theory of knowledge. Finally, I briefly explain how this analysis sheds light on the ordinary language fallibilism of Moore (1939), Austin (1961), Wittgenstein (1969) and Chisholm (1982). (shrink)

The Gettier problem has stymied epistemologists. But, whether or not this problem is resolvable, we still must face an important question: Why does the Gettier problem arise in the first place? So far, philosophers have seen it as either a problem peculiar to the concept of knowledge, or else an instance of a general problem about conceptual analysis. But I would like to steer a middle course. I argue that the Gettier problem arises because knowledge is a thick concept, and (...) a Gettier-like problem is just what we should expect from attempts at analyzing a thick concept. Section 2 is devoted to establishing the controversial claim that knowledge is thick, and, in Sect. 3, I show that there is a general problem for analyzing thick concepts of which the Gettier problem is a special instance. I do not take a stand on whether the Gettier problem, or its general counterpart, is resolvable. My primary aim is to bring these problems into better focus. (shrink)

This essay addresses the question of when evidence for a stronger claim H1 also constitutes evidence for a weaker claim H2. Although the answer “Always” is tempting, it is false on a natural Bayesian conception of evidence. This essay first describes some prima facie counterexamples to this answer and surveys some weaker answers and rejects them. Next, it proposes an answer, which appeals to the “Dragging Condition.” After explaining and arguing for its use of the Dragging Condition, the essay argues (...) that the Dragging Condition provides a general account of, and solution to, the counterexamples with which the essay began. The essay briefly discusses the relevance of the Dragging Condition to the recently much-discussed topic of “transmission failure” in epistemology, applies the Dragging Condition to the problem of “bootstrapping” in epistemology, and discusses three important objections to the view defended in the essay.

Jonathan Vogel has presented a disturbing problem for reliabilism. 1 Reliabilists claim that knowledge is reliably produced true belief. Reliabilism is, of course, a version of externalism, and on such a view, a knower need have no knowledge, no justified belief, indeed, no conception that his or her belief is reliably produced. It is the fact that the knower's true belief is reliably produced which makes it a case of knowledge, not any appreciation of this fact. But Vogel now argues (...) that reliabilists will, by a process he calls ‘bootstrapping’, far too easily gain knowledge of the reliability of the processes by which their knowledge is produced. For the reliabilist, knowledge which should be difficult to come by is quite easily and trivially attainable, Vogel argues. And this, of course, seems to show a fundamental flaw in the reliabilist conception of knowledge.One solution to this puzzle is offered by van Cleve . Bootstrapping may seem unattractive, van Cleve claims, but only when we fail to consider the alternative. Any epistemological view which does not legitimate bootstrapping, he argues, will inevitably lead to scepticism. And if the choice is between bootstrapping and scepticism, van Cleve will happily accept bootstrapping.It would be nice, certainly, if we could avoid this unpalatable dilemma.Vogel's argument is disturbingly straightforward. Suppose that Roxanne gains knowledge that the gas tank in her car is full by looking at her gas gauge, and let us further suppose that Roxanne has no reason at all to believe that her gas gauge is reliable. As Vogel points out, reliabilists cannot object to these assumptions. Precisely because reliabilism is a version of externalism, reliabilists must allow that there are cases meeting these very conditions. That is, reliabilists must allow that one can gain knowledge by way of a …. (shrink)

: Duncan Pritchard has recently highlighted the problem of veritic epistemic luck and claimed that a safety‐based account of knowledge succeeds in eliminating veritic luck where virtue‐based accounts and process reliabilism fail. He then claims that if one accepts a safety‐based account, there is no longer a motivation for retaining a commitment to reliabilism. In this article, I delineate several distinct safety principles, and I argue that those that eliminate veritic luck do so only if at least implicitly committed to (...) reliabilism. (shrink)

According to evidentialists about inferential justification, an agent’s evidence—and only her evidence—determines which inferences she would be justified in making, whether or not she in fact makes them. But there seem to be cases in which two agents would be justified in making different inferences from a shared body of evidence, merely in virtue of the different competences those agents possess. These sorts of cases suggest that evidence does not have the pride of place afforded to it by evidentialists; competence (...) seems to play at least as important a role as evidence in explaining which inferences an agent would be justified in making. -/- In this paper, I consider how two versions of evidentialism about inferential justification might try to account for the role of competence in inference, and I present problems specific to each version. I end by sketching and briefly defending an alternative to these evidentialist views, “inferential dogmatism”. While dogmatic views have gotten some attention in debates around non-inferential justification, they have largely been ignored in debates around inferential justification and are to that extent novel.

Crispin Wright’s epistemic response to McKinsey’s paradox is to argue that introspective knowledge of the first premise fails to transmit across the semantic externalist entailment in the second premise to the conclusion that one has such untoward knowledge of the external world. This paper argues first that Stewart Cohen and Jonathan Vogel’s bootstrapping arguments suffer from a novel kind of epistemic circularity, which triggers failure of transmission but allows for the possibility of basic perceptual knowledge. It is then argued that (...) McKinsey’s paradox falls out as a special case of this template for transmission failure. The circularity in play is semantic: the paradox illicitly imports semantically relevant properties of knowledge-individuating sources into the contents of the knowledge states that those sources individuate by instantiating those properties. Importantly, this diagnosis permits the possibility of basic introspective knowledge as propounded by Tyler Burge and other semantic ex.. (shrink)

Process reliabilists hold that in order for a belief to be justified, it must result from a reliable cognitive process. They also hold that a belief can be basically justified: justified in this manner without having any justification to believe that belief is reliably produced. Fumerton (1995), Vogel (2000), and Cohen (2002) have objected that such basic justification leads to implausible easy justification by means of either epistemic closure principles or so-called track record arguments. I argue that once we carefully (...) distinguish closure principles from transmission principles, and epistemic consequences from epistemic preconditions, neither version of this objection succeeds.

Reliabilists accept the possibility of basic knowledge—knowledge that p in virtue of the reliability of some belief-producing process r without antecedent knowledge that r is reliable. Cohen (Philos Phenomenol Res 65:309–329, 2002 , Philos Phenomenol Res 70:417–430, 2005 ) and Vogel (J Philos 97:602–623, 2000 , J Philos 105:518–539, 2008 ) have argued that one can bootstrap knowledge that r is reliable from basic knowledge. This paper provides a diagnosis of epistemic bootstrapping, and then shows that recent attempts at embracing (...) bootstrapped knowledge are found wanting. Instead it is argued that such arguments are afflicted by a novel kind of generalized epistemic circularity. The ensuing view is defended against various objections, and an explanation of the source of that circularity is offered. (shrink)

According to Perceptual Fundamentalism we can have justified perceptual beliefs solely in virtue of having perceptual experiences with corresponding contents. Recently, it has been argued that Perceptual Fundamentalism entails that it is possible to gain an a priori justified belief that perception is reliable by engaging in a suppositional reasoning process of a priori bootstrapping. But I will show that Perceptual Fundamentalists are not committed to a priori bootstrapping being a rational reasoning process. On the most plausible versions of Perceptual (...) Fundamentalism, a priori bootstrapping cannot be used to rationally support anti-sceptical beliefs about the reliability of perception. Moreover, seeing why Perceptual Fundamentalists are not committed to a priori bootstrapping will help us to better understand the nature of the perceptual entitlements that Perceptual Fundamentalists posit, or at least should posit.

_ Source: _Page Count 17 Michael Huemer, Ernest Sosa, and Jonathan Vogel have offered a critique of the sensitivity condition on knowledge. According to them, the condition implies that you cannot know of any particular proposition that you do not falsely believe it. Their arguments rest on the claim that you cannot sensitively believe of any particular proposition that you do not falsely believe it. However, as we shall see, these philosophers are mistaken. You can do so. That said, these (...) philosophers were close to the mark. There are some related propositions that you cannot believe sensitively. These propositions are interesting in another respect: they can be used to construct a new skeptical argument that is superior in some respects to a more traditional skeptical argument. This new skeptical argument also reveals insights about the relationship between internalism, externalism, and skepticism. (shrink)

Moore’s paradox supports the principle of “metacoherence”, i.e., that if one categorically believes that P, one is committed to accepting that one knows that P. The principle raises puzzles about how, when one has justification for P, one also has justification for the claim that one knows P. I reject a skeptical answer as well as a bootstrapping answer, and I suggest that we typically have independent justification for the claim that we know P.

Hume's epistemological legacy is often perceived as a predominantly negative sceptical one. His infamous problem of induction continues to perplex philosophers to this day, and many of his sceptical worries maintain their interest in contemporary eyes (e.g. with regard to reason, the senses, substance, causation). Yet Hume's positive epistemological contributions also hold significance for philosophy in this day and age. In this paper, I aim to situate Hume's epistemology in a more contemporary context, particularly with regard to the theme of (...) reliabilism that runs throughout this epistemology. This will take the shape of examining correspondences and contrasts between Hume's epistemologies in the Treatise and Enquiry and reliabilism, as well as an examination of how Hume's framework might handle some major challenges for reliabilist epistemologies. In particular, I argue that that while Hume is tempted to an epistemology that is intimately tied to truth in the Treatise, he backs away when confronted with the excesses of scepticism in the conclusion of Book 1, and winds up with an epistemology most similar to the contemporary epistemological frameworks of dogmatism and phenomenal conservatism. Yet, largely because of his reliance on the passions (a respect in which he diverges from these two contemporary frameworks), the epistemology of the Treatise remains crucially dissociated from truth. Meanwhile, in the first Enquiry, he proceeds to develop a two-tiered epistemological framework that first accords all our justification with default authority, and then founds all-things-considered epistemic justification on our evidence for the reliability of our faculties. The first tier most resembles the contemporary epistemological framework of conservatism, while the second tier most closely resembles approved-list reliabilism. In this, a clear reliabilist thread runs through the epistemology of the Enquiry. I will also argue that although Hume did not appear to fully appreciate one of the most significant challenges for reliabilism-that is, the generality problem-his philosophical framework nevertheless contains the beginnings of a response to it.

Many views rely on the idea that it can never be rational to have high confidence in something like, “P, but my evidence doesn’t support P.” Call this idea the “Non-Akrasia Constraint”. Just as an akratic agent acts in a way she believes she ought not act, an epistemically akratic agent believes something that she believes is unsupported by her evidence. The Non-Akrasia Constraint says that ideally rational agents will never be epistemically akratic. In a number of recent papers, the (...) Non-Akrasia Constraint has been called into question. The goal of this paper is to defend it... for the most part. (shrink)

Epistemic closure has been a central issue in epistemology over the last forty years. According to versions of the relevant alternatives and subjunctivist theories of knowledge, epistemic closure can fail: an agent who knows some propositions can fail to know a logical consequence of those propositions, even if the agent explicitly believes the consequence (having “competently deduced” it from the known propositions). In this sense, the claim that epistemic closure can fail must be distinguished from the fact that agents do (...) not always believe, let alone know, the consequences of what they know—a fact that raises the “problem of logical omniscience” that has been central in epistemic logic. This paper, part I of II, is a study of epistemic closure from the perspective of epistemic logic. First, I introduce models for epistemic logic, based on Lewis’s models for counterfactuals, that correspond closely to the pictures of the relevant alternatives and subjunctivist theories of knowledge in epistemology. Second, I give an exact characterization of the closure properties of knowledge according to these theories, as formalized. Finally, I consider the relation between closure and higher-order knowledge. The philosophical repercussions of these results and results from part II, which prompt a reassessment of the issue of closure in epistemology, are discussed further in companion papers. As a contribution to modal logic, this paper demonstrates an alternative approach to proving modal completeness theorems, without the standard canonical model construction. By “modal decomposition” I obtain completeness and other results for two non-normal modal logics with respect to new semantics. One of these logics, dubbed the logic of ranked relevant alternatives, appears not to have been previously identified in the modal logic literature. More broadly, the paper presents epistemology as a rich area for logical study. (shrink)

Some hold that beliefs arising out of certain sources such as perceptual experience enjoy a kind of entitlement—as one is entitled to believe what is thereby presented as true, at least unless further evidence undermines that entitlement. This is commonly understood to require that default epistemic entitlement is a non-evidential kind of epistemic warrant. Our project here is to challenge this common, non-evidential, conception of epistemic entitlement. We will argue that although there are indeed basic beliefs with default entitlement status, (...) typically the kind of default entitlement they possess is primarily a matter of the evidential support that accrues to them, both synchronically and diachronically, from wider mental states beyond the specific sensory-perceptual experiences that spawn them. We will call this status evidentially embedded epistemic entitlement—as distinct from entitlement as commonly understood in the literature, which we will call evidentially insular. Epistemic entitlement normally is characterized in the manner set forth in the first paragraph above, viz., as a form of default epistemic warrant that a given belief possesses independently of any other beliefs. We suggest that not all evidential support is managed at the level of belief. Thus, leaves room for the possibility of an epistemically embedded kind of entitlement. Here we develop the needed conception of entitlement drawing on Henderson and Horgan’s ideas of a kind of “iceberg epistemology.”. (shrink)

While Process Reliabilism has long been regarded by many as a version of Foundationalism, this paper argues that there is a version of Process Reliabilism that can also been seen as at least a partial vindication of Coherentism as well. The significance of this result lies in what it tells us both about the prospects for a plausible Process Reliabilism, but also about the old-school debate between Foundationalists and Coherentists.

The evaluation of arguments and argumentation is best understood epistemologically. Epistemic circularity is not formally defective but it may be epistemologically objectionable. Sorenson's doubts about the syntactic approach to circularity are endorsed with qualifications. One explanation of an argument's goodness is its ability to produce justified belief in its conclusion by means of justified belief in its premises, but matters are not so simple for interpersonal argumentation. Even when an argument's premises and conclusion are justified for a speaker, this justifiedness (...) may not be transmissible to every hearer. Still, an epistemic approaeh is instructive. Arguing in enthymemes can be legitimate, e.g., because enthymemes can help produce justified persuasion in an audience that supplies the missing premises. (shrink)

Carroll's short piece “What the Tortoise said to Achilles” in many ways anticipates issues that arise in a number of contemporary controversies. One might argue, for example, that initially plausible attempts to deal with the problem of easy knowledge will land one in the unfortunate position of Achilles who followed the Tortoise down a road that leads to vicious infinite regress. Or consider the conditions required for inferential justification. For idealized inferential justification, I have defended the view that to be (...) justified in believing P on the basis of E one needs to be not only justified in believing E, but justified in believing that E makes probable P. And again, critics have argued that such a strong requirement fails to learn the lesson that Achilles should have been taught by the Tortoise. Even more generally, one might well argue that strong access internalists will need to deal with a variation of Carroll's puzzle even for their accounts of non-inferential justification. In this paper I'll examine these controversies with a mind to reaching a conclusion about just exactly how one can accept intellectually demanding conditions on justified belief without encountering vicious regress.

According to process reliabilism, a belief produced by a reliable belief-forming process is justified. I introduce problems for this theory on any account of reliability. Does the performance of a process in some domain of worlds settle its reliability? The theories that answer “Yes” typically fail to state the temporal parameters of this performance. I argue that any theory paired with any plausible parameters has implausible implications. The theories that answer “No,” I argue, thereby lack essential support and exacerbate familiar (...) problems. There are new reasons to avoid any reliability conditions on justification. (shrink)

Reliabilism is an intuitive and attractive view about epistemic justification. However, it has many well-known problems. I offer a novel condition on reliabilist theories of justification. This method coherence condition requires that a method be appropriately tested by appeal to a subject’s other belief-forming methods. Adding this condition to reliabilism provides a solution to epistemic circularity worries, including the bootstrapping problem.

The problem of epistemic bootstrapping requires explaining, in a principled manner, why a subject who engages in bootstrapping fails to know the conclusion of her reasoning. Existing proposed solutions to the problem provide unsatisfactory explanations regarding the bootstrapper's ignorance. This paper puts forward a novel solution and argues that it satisfactorily explains the ignorance of the bootstrapper, while avoiding the difficulties that other proposals face. Section 1 explains what epistemic bootstrapping is, defines the problem it poses for a theory of (...) knowledge, and outlines the basic desiderata demanded of any acceptable solution to the problem. Section 2 explicates the proposal I defend throughout the rest of the paper. Here, I contend that the wrong−making feature of bootstrapping which ultimately explains the bootstrapper's ignorance is a failure to use an independent source in checking the accuracy of the reports of a given source. I call this explanation the “Independence proposal.” Section 2 also argues that the phenomenon of bootstrapping is broader than is usually assumed; there are cases of bootstrapping that do not fit the superficial structure of the prototypical cases discussed in the literature, and any good proposal should apply to these as well. Section 3 argues that the independence proposal does better than other current proposals in fulfilling the desiderata identified in Section 1. Section 4 sums up the central contributions of the paper. (shrink)

How should you take into account the opinions of an advisor? When you completely defer to the advisor's judgment, then you should treat the advisor as a guru. Roughly, that means you should believe what you expect she would believe, if supplied with your extra evidence. When the advisor is your own future self, the resulting principle amounts to a version of the Reflection Principle---a version amended to handle cases of information loss. When you count an advisor as an epistemic (...) peer, you should give her conclusions the same weight as your own. Denying that view---call it the ``equal weight view''---leads to absurdity: the absurdity that you could reasonably come to believe yourself to be an epistemic superior to an advisor simply by noting cases of disagreement with her, and taking it that she made most of the mistakes. Accepting the view seems to lead to another absurdity: that one should suspend judgment about everything that one's smart and well-informed friends disagree on, which means suspending judgment about almost everything interesting. But despite appearances, the equal weight view does not have this absurd consequence. Furthermore, the view can be generalized to handle cases involving not just epistemic peers, but also epistemic superiors and inferiors. (shrink)

I am concerned with epistemic closure—the phenomenon in which some knowledge requires other knowledge. In particular, I defend a version of the closure principle in terms of analyticity; if an agent S knows that p is true and that q is an analytic part of p, then S knows that q. After targeting the relevant notion of analyticity, I argue that this principle accommodates intuitive cases and possesses the theoretical resources to avoid the preface paradox.

Street’s “Darwinian Dilemma” is a well-known epistemological objection to moral realism. In this paper, I argue that “third-factor” replies to this argument on behalf of the moral realist, as popularized by Enoch :413–438, 2010, Taking morality seriously: a defense of robust realism, Oxford University Press, Oxford, 2011), Skarsaune :229–243, 2011) and Wielenberg :441–464, 2010, Robust ethics: the metaphysics and epistemology of godless normative realism, Oxford University Press, Oxford, 2014), cannot succeed. This is because they are instances of the illegitimate form (...) of reasoning known as “bootstrapping.” The phenomenon of bootstrapping has been discussed in detail, most notably by Vogel :602–623, 2000) and Cohen :309–329, 2002), in a different context as an objection to reliabilism and related theories of knowledge. I introduce four different characterizations of the error of bootstrapping from the epistemic literature in order to argue that the form of reasoning exemplified by third-factor replies would be deemed illegitimate by every one of them. I conclude that the moral realist should abandon third-factor replies, or else suggest a novel diagnosis for what goes wrong in bootstrapping cases that does not apply equally to the realist’s form of argument. However, I am not optimistic about the prospects for this latter strategy. (shrink)

Consider the Evidence Question: When and under what conditions is proposition P evidence for some agent S? Silins (Philos Perspect 19:375–404, 2005) has recently offered a partial answer to the Evidence Question. In particular, Silins argues for Evidential Internalism (EI), which holds that necessarily, if A and B are internal twins, then A and B have the same evidence. In this paper I consider Silins’s argument, and offer two response on behalf of Evidential Externalism (EE), which is the denial of (...) Evidential Internalism. The first response claims that the allegedly unattractive consequence for EE is not so unattractive. The second response takes the form of a tu quoque, demonstrating that a structurally similar argument can be constructed against EI. The two responses play off one another: objecting to the first puts pressure on one to accept the other. Taken together, the two responses have important ramifications for how we answer the Evidence Question, and how we think about evidence in general. (shrink)

Epistemic closure under known implication is the principle that knowledge of "p" and knowledge of "p implies q", together, imply knowledge of "q". This principle is intuitive, yet several putative counterexamples have been formulated against it. This paper addresses the question, why is epistemic closure both intuitive and prone to counterexamples? In particular, the paper examines whether probability theory can offer an answer to this question based on four strategies. The first probability-based strategy rests on the accumulation of risks. The (...) problem with this strategy is that risk accumulation cannot accommodate certain counterexamples to epistemic closure. The second strategy is based on the idea of evidential support, that is, a piece of evidence supports a proposition whenever it increases the probability of the proposition. This strategy makes progress and can accommodate certain putative counterexamples to closure. However, this strategy also gives rise to a number of counterintuitive results. Finally, there are two broadly probabilistic strategies, one based on the idea of resilient probability and the other on the idea of assumptions that are taken for granted. These strategies are promising but are prone to some of the shortcomings of the second strategy. All in all, I conclude that each strategy fails. Probability theory, then, is unlikely to offer the account we need. (shrink)

Like David Silver before them, Erik Baldwin and Michael Thune argue that the facts of religious pluralism present an insurmountable challenge to the rationality of basic exclusive religious belief as construed by Reformed Epistemology. I will show that their argument is unsuccessful. First, their claim that the facts of religious pluralism make it necessary for the religious exclusivist to support her exclusive beliefs with significant reasons is one that the reformed epistemologist has the resources to reject. Secondly, they fail to (...) demonstrate that it is impossible for basic religious beliefs to return to their properly basic state after defeaters against them have been defeated. Finally, I consider whether there is perhaps a similar but better argument in the neighbourhood and conclude in the negative. Reformed Epistemology's defence of exclusivism thus remains undefeated.
