I will assume here the defenses of epistemic infinitism are adequate and inquire as to the variety standpoints within the view. I will argue that infinitism has three varieties depending on the strength of demandingness of the infinitist requirement and the purity of its conception of epistemic justification, each of which I will term strong pure, strong impure, and weak impure infinitisms. Further, I will argue that impure infinitisms have the dialectical advantage.

Descartes’ demon is a deceiver: the demon makes things appear to you other than as they really are. However, as Descartes famously pointed out in the Second Meditation, not all knowledge is imperilled by this kind of deception. You still know you are a thinking thing. Perhaps, though, there is a more virulent demon in epistemic hell, one from which none of our knowledge is safe. Jonathan Schaffer thinks so. The “Debasing Demon” he imagines threatens knowledge not via the truth (...) condition on knowledge, but via the basing condition. This demon can cause any belief to seem like it’s held on a good basis, when it’s really held on a bad basis. Several recent critics, Conee, Ballantyne & Evans ) grant Schaffer the possibility of such a debasing demon, and argue that the skeptical conclusion doesn’t follow. By contrast, we argue that on any plausible account of the epistemic basing relation, the “debasing demon” is impossible. Our argument for why this is so gestures, more generally, to the importance of avoiding common traps by embracing mistaken assumptions about what it takes for a belief to be based on a reason.

Spiritual formation currently lacks a robust epistemology. Christian theology and philosophy often spend more time devoted to an epistemology of propositions rather than an epistemology of knowing persons. This paper is an attempt to move toward a more robust account of knowing persons in general and God in particular. After working through various aspects of the nature of this type of knowledge this theory is applied to specific issues germane to spiritual formation, such as the justification of understanding spiritual growth (...) on an integrative and holistic (heart and mind) model, the reality of hearing God’s voice, and knowing his activity, as well as how such a theory should change the shape of sermons, evangelism, and apologetics.

In this paper we argue that Michael Huemer’s phenomenal conservatism—the internalist view according to which our beliefs are prima facie justified if based on how things seems or appears to us to be—doesn’t fall afoul of Michael Bergmann’s dilemma for epistemological internalism. We start by showing that the thought experiment that Bergmann adduces to conclude that is vulnerable to his dilemma misses its target. After that, we distinguish between two ways in which a mental state can contribute to the justification (...) of a belief: the direct way and the indirect way. We identify a straightforward reason for claiming that the justification contributed indirectly is subject to Bergmann’s dilemma. Then we show that the same reason doesn’t extend to the claim that the justification contributed directly is subject to Bergmann’s dilemma. As is the view that seemings or appearances contribute justification directly, we infer that Bergmann’s contention that his dilemma applies to is unmotivated. In the final part, we suggest that our line of response to Bergmann can be used to shield other types of internalist justification from Bergmann’s objection. We also propose that seeming-grounded justification can be combined with justification of one of these types to form the basis of a promising version of internalist foundationalism. (shrink)

This paper continues a recent exchange in this journal concerning explanationist accounts of epistemic justification. In the first paper in this exchange, Byerly argues that explanationist views judge that certain beliefs about the future are unjustified when in fact they are justified. In the second paper, McCain defends a version of explanationism which he argues escapes Byerly’s criticism. Here we contribute to this exchange in two ways. In the first section, we argue that McCain’s defense of explanationism against Byerly’s objection (...) is unsuccessful. Then, in the second section, we develop an independent objection to explanationism from a different direction. If our arguments in each section are sound, then not only do explanationist accounts of epistemic justification judge beliefs that are justified to be unjustified, but they judge beliefs that are unjustified to be justified. Explanationism faces problems on both sides. (shrink)

According to the explanationist, we can rely on inference to best explanation to justifiably believe familiar skeptical hypotheses are false. On this view, commonsense beliefs about the existence and character of familiar, medium-sized dry goods provides the best explanation of our evidence and so justifies our belief that we're not brains-in-vats. This explanationist approach seems prima facie plausible until we press the explanationist to tell us what the data is that we're trying to explain by appeal to our beliefs about (...) external objects and how we could have access to it.

The New Evil Demon Problem is often seen as a serious objection to externalist theories of justification. In fact, some internalists think it is a decisive counterexample to externalism. Recently, Moon has argued that internalists face their own New Evil Demon Problem. According to Moon, it is possible for a demon to remove one’s unaccessed mental states while leaving the justificatory status of her accessed mental states unaffected. Since this is contrary to the claims of many forms of internalism, Moon (...) maintains that his New Evil Demon Problem for Internalism shows that internalists face a problem that is just as troubling as the original NEDP. I argue that moderate internalists have nothing to fear from Moon’s demon. (shrink)

The distinction between a priori knowledge and a posteriori knowledge has come under attack in the recent literature by Philip Kitcher, John Hawthorne, C. S. Jenkins, and Timothy Williamson. Evaluating the attacks requires answering two questions. First, have they hit their target? Second, are they compelling? My goal is to argue that the attacks fail because they miss their target. Since the attacks are directed at a particular concept or distinction, they must accurately locate the target concept or distinction. Accurately (...) locating the target concept or distinction requires correctly articulating that concept or distinction. The attacks miss their target because they fail to correctly articulate the target concept or distinction. I go on to present a different challenge to the a priori-a posteriori distinction. This challenge is not directed at the coherence or significance of the distinction. Its target is the traditional view that all knowledge (or justified belief) is either a priori or a posteriori.

According to Roderick Chisholm, there are three ways of responding to the Problem of the Criterion and they all leave something to be desired. Michael DePaul, Paul Moser, and Earl Conee have each proposed variations of a fourth way of responding to this problem that rely on reflective equilibrium. We argue that these four options for responding to the Problem of the Criterion leave one with a tough choice: accept one of the three that Chisholm describes or DePaul’s reflective equilibrium (...) approach and beg the question or accept a reflective equilibrium response of the sort Conee and Moser propose and embrace epistemic circularity.

The dissertation examines the nature and epistemic implications of epistemic source circularity. An argument exhibits this type of circularity when at least one of the premises is produced by a belief source the conclusion says is legitimate, e.g. a track record argument for the legitimacy of sense perception that uses premises produced by sense perception. In chapter one I examine this and several other types of circularity, identifying relevant similarities and differences between them. In chapter two I discuss the differences (...) between internalist and externalist analyses of justification. I examine in detail foundationalist and non-foundationalist versions of internalism, and go on to consider how one might characterize externalism: either negatively, by denying particular internalist theses, or positively, in terms of a theory offering different conditions for justification. I discuss the views of reliabilist foundationalists at length. In chapter three I present the internalist objection to externalism that the latter mistakenly permit one to be justified in believing the conclusion of an epistemic source circular inference. I explain the externalists' response that it is not in virtue of their externalism that they permit epistemic source circularity but rather their foundationalism; thus, internalist foundationalists must permit epistemic source circularity as well. I evaluate the positions of several internalists, most of them explicitly foundationalists, and argue that they too cannot avoid permitting epistemic source circularity. In the final chapter I consider whether such circularity is vicious, even though both internalist and externalist foundationalists permit it. I argue that one can sustain an objection to epistemic source circularity by imposing a non-question-begging requirement on justification and explain how respecting this requirement leads one to a non-foundationalist view. I conclude by considering the objection that question-begging leads to a certain arbitrariness in belief formation that should give the foundationalist pause when it comes to determining, at the beginning of inquiry, which beliefs are justified and which are not. The dissertation is primarily concerned with making clear the possible skeptical and non-skeptical positions one can take towards epistemic source circularity. I do not argue for the truth of a particular metaepistemology. (shrink)

The notion of cognitive act is of importance for an epistemology that is apt for constructive type theory, and for epistemology in general. Instead of taking knowledge attributions as the primary use of the verb 'to know' that needs to be given an account of, and understanding a first-person knowledge claim as a special case of knowledge attribution, the account of knowledge that is given here understands first-person knowledge claims as the primary use of the verb 'to know'. This means (...) that a cognitive act is an act that counts as cognitive from a first-person point of view. The method of linguistic phenomenology is used to explain or elucidate our epistemic notions. One of the advantages of the theory is that an answer can be given to some of the problems in modern epistemology, such as the Gettier problem. (shrink)

According to foundationalism, some beliefs are justified but do not depend for their justification on any other beliefs. According to access internalism, a subject is justified in believing some proposition only if that subject is aware of or has access to some reason to think that the proposition is true or probable. In this paper I discusses a fundamental challenge to internalist foundationalism often referred to as the Sellarsian dilemma. I consider three attempts to respond to the dilemma – phenomenal (...) conservatism, BonJour’s classical foundationalism, and Fumerton’s classical foundationalism. I argue that, of these three, only the last seems to avoid getting impaled on one or the other horn of the dilemma. I end by responding to some concerns with Fumerton’s account. (shrink)

I focus on a key argument for global external world scepticism resting on the underdetermination thesis: the argument according to which we cannot know any proposition about our physical environment because sense evidence for it equally justifies some sceptical alternative (e.g. the Cartesian demon conjecture). I contend that the underdetermination argument can go through only if the controversial thesis that conceivability is per se a source of evidence for metaphysical possibility is true. I also suggest a reason to doubt that (...) conceivability is per se a source of evidence for metaphysical possibility, and thus to doubt the underdetermination argument. (shrink)

Conservatism about perceptual justification tells us that we cannot have perceptual justification to believe p unless we also have justification to believe that perceptual experiences are reliable. There are many ways to maintain this thesis, ways that have not been sufficiently appreciated. Most of these ways lead to at least one of two problems. The first is an over-intellectualization problem, whereas the second problem concerns the satisfaction of the epistemic basing requirement on justified belief. I argue that there is at (...) least one Conservative view that survives both difficulties, a view which has the further ability to undercut a crucial consideration that has supported Dogmatist views about perceptual justification. The final section explores a tension between Conservatism and the prospects of having a completely general account of propositional justification. Ironically, the problem is that Conservatives seem committed to making the acquisition of propositional justification too easy. My partial defense of Conservatism concludes by suggesting possible solutions to this problem. (shrink)

The epistemology of monotheism offered by philosophers has given inadequate attention to the kind of foundational evidence to be expected of a personal God whose moral character is ’agapeic’, or perfectly loving, toward all other agents. This article counters this deficiency with the basis of a theistic epistemology that accommodates the distinctive moral character of a God worthy of worship. It captures the widely neglected ’agonic’, or struggle-oriented, character of a God who seeks, by way of personal witness and intentional (...) action, to realize and manifest ’agape’ among humans who suffer from selfishness. In doing so, the article identifies the overlooked role of personifying evidence of God in human moral character formation. In agreement with some prominent New Testament themes, the new perspective offered ties the epistemology of monotheism to robust ’agapeic’ morality in a way that makes such epistemology ethically challenging for inquirers about God’s existence. Accordingly, s. (shrink)

Explanationism holds that a person's evidence supports a proposition just in case that proposition is part of the best available explanation for the person's evidence. I argue that explanationism faces a serious difficulty when it comes to justified beliefs about the future. Often, one's evidence supports some proposition about the future but that proposition is not part of the best available explanation for one's evidence. Attempts to defend explanationism against this charge are unattractive. Moving to a modified better contrastive explanation (...) account will help with these cases, but it will face other difficulties. (shrink)

This paper proposes and defends an account of what it is to act for reasons. In the first part, I will discuss the desire-belief and the deliberative model of acting for reasons. I will argue that we can avoid the weaknesses and retain the strengths of both views, if we pursue an alternative according to which acting for reasons involves taking something as a reason. In the main part, I will develop an account of what it is to take something (...) as a reason for action. On the basis of this, I will then offer a new account of what it is to act for reasons.

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.

Infallibilism is the claim that knowledge requires that one satisfies some infallibility condition. I spell out three distinct such conditions: epistemic, evidential and modal infallibility. Epistemic infallibility turns out to be simply a consequence of epistemic closure, and is not infallibilist in any relevant sense. Evidential infallibilism i s unwarranted but it is not an satisfactory characterization of the infallibilist intuition. Modal infallibility, by contrast, captures the core infallibilist intuition, and I argue that it is required to solve the Gettier (...) problem and account for lottery cases. Finally, I discuss whether modal infallibilism has sceptical consequences and argue that it is an open question whose answer depends on one’s account of alethic possibility. (shrink)

Commonsense epistemology regards perceptual experience as a distinctive source of knowledge of the world around us, unavailable in ‘blindsight’. This is often interpreted in terms of the idea that perceptual experience, through its representational content, provides us with justifying reasons for beliefs about the world around us. I argue that this analysis distorts the explanatory link between perceptual experience and knowledge, as we ordinarily conceive it. I propose an alternative analysis, on which representational content plays no explanatory role: we make (...) perceptual knowledge intelligible by appeal to experienced objects and features. I also present an account of how the commonsense scheme, thus interpreted, is to be defended: not by tracing the role of experience to its contribution in meeting some general condition on propositional knowledge (such as justification), but by subverting the assumption that it has to be possible to make the role of experience intelligible in terms of some such contribution. (shrink)

Coherentists on epistemic justification claim that all justification is inferential, and that beliefs, when justified, get their justification together (not in isolation) as members of a coherent belief system. Some recent work in formal epistemology shows that “individual credibility” is needed for “witness agreement” to increase the probability of truth and generate a high probability of truth. It can seem that, from this result in formal epistemology, it follows that coherentist justification is not truth-conducive, that it is not the case (...) that, under the requisite conditions, coherentist justification increases the probability of truth and generates a high probability of truth. I argue that this does not follow. (shrink)

The concept of evidence is among the central concerns of epistemology broadly construed. As such, it has long engaged the intellectual energies of both philosophers of science and epistemologists of a more traditional variety. Here I briefly survey some of the more important ideas to have emerged from this tradition of reflection. I then look somewhat more closely at an issue that has recently come to the fore, largely as a result of Williamson's Knowledge and Its Limits: that of whether (...) one's evidence supervenes on one's non-factive mental states. (shrink)

It is sometimes suggested that there are two kinds of reasoning: inferential reasoning and non-inferential reasoning. However, it is not entirely clear what the difference between these two kinds of reasoning is. In this paper, I try to answer the question what this difference is. I first discuss three answers to this question that I argue are unsatisfactory. I then give a different answer to this question, and I argue that this answer is satisfactory. I end by showing that this (...) answer can help to resolve some disagreements in which the difference between inferential and noninferential reasoning plays a role. (shrink)

This article surveys work in epistemology since the mid-1980s. It focuses on contextualism about knowledge attributions, modest forms of foundationalism, and the internalism/externalism debate and its connections to the ethics of belief.

One of the most influential arguments for the coherence theory of empirical justification is BonJours a priori argument from the internalist regress. According to this argument, foundationalism cannot solve the problem of the internalist regress since internalism is incompatible with basic beliefs. Hence, coherentism seems to be the only option. In my article I contend that this argument is doomed to failure. It is either too strong or too weak. Too strong, since even coherentism cannot stop the internalist regress in (...) any legitimate way. In order to demonstrate this claim I will discuss various coherentist strategies. Too weak, since, were coherentism able to stop the regress, the argument against foundationalism would collapse. (shrink)

This article describes abductions as special patterns of inference to the best explanation whose structure determines a particularly promising abductive conjecture and thus serves as an abductive search strategy. A classification of different patterns of abduction is provided which intends to be as complete as possible. An important distinction is that between selective abductions, which choose an optimal candidate from given multitude of possible explanations, and creative abductions, which introduce new theoretical models or concepts. While selective abduction has dominated the (...) literature, creative abductions are rarely discussed, although they are essential in science. The article introduces several kinds of creative abductions, such as theoretical model abduction, common cause abduction and statistical factor analysis, and illustrates them by various real case examples. It is suggested to demarcate scientifically fruitful abductions from purely speculative abductions by the criterion of causal unification. (shrink)

Externalist analyses of justification typically include some sort of reliability requirement. But the fact that the beliefs of a demon victim can be justified despite their being formed in completely unreliable ways suggests that reliability isn’t required for justification. In this paper, I propose an analysis of justification in terms of proper function that enables us to hang on to the externalism without the reliability requirement. As an added bonus, the proposed analysis of justification yields an account of the elusive (...) connection between justification and truth. (shrink)

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)

It is commonly thought that we depend fundamentally on the “evidence of the senses” for our empicial beliefs, including and most directly, our beliefs about our local environment, the spatial world around us. The ultimate evidence we have for our perceptual beliefs is provided in some way by perception or perceptual experience. But what is this evidence? There seem to be three main options: external factualism allows that the evidence include facts about the external world; internal factualism takes facts that (...) involve only the internal, mental world—like facts about one’s perceptual experiences or appearances—to count as one’s perceptual evidence; and non-factualism takes propositions, including false ones, to count as evidence—for example, propositional contents of appearances or seemings. We shall see that all these options face significant challenges. Some might conclude that perceptual beliefs can be justified without depending on evidence. Others might choose to accept skepticism: our perceptual beliefs are not justified. I shall end, however, by tentatively suggesting that there is a sort of internal fact that is a plausible candidate for perceptual evidence that has been overlooked. (shrink)

At the core of evidentialism lies a very plausible claim: rational thinkers follow their evidence. While this seems to be a very intuitive, almost trivial, claim, providing a full and complete evidentialist theory is complicated. In this entry, I begin with elucidating what kind of theory evidentialists aim to provide us with. I will show that, in order to provide a complete evidentialist theory, we have to provide a lot of details on what evidence is and how it relates to (...) the proposition it’s evidence for, as well as the agent possessing such evidence. I then consider objections arising for the most popular answers one can give to such questions. I conclude by considering old and new challenges that arise for evidentialism, regardless of the specific version one endorses. (shrink)

This article presents an argument for atheism that contains a premise stated from the first-person perspective and that is intended to rationally persuade people who satisfy certain conditions. The argument also contains a premise about what God would do, if God existed, that is acceptable to theists and is affirmed in some major monotheistic religious traditions. This article explains how the argument differs from some other familiar arguments for atheism and then discusses some critical responses to it.

Many metaethicists endorse a cognitive constraint which links the reasons for which we act or hold attitudes (motivating reasons) to normative reasons (reasons that speak in favour of an action or attitude). As traditionally formulated, this constraint (known as the Taking Condition) requires that an agent’s motivating reasons are mentally represented by her as corresponding normative reasons. In response to the charge that the Taking Condition is overly demanding, Errol Lord and Kurt Sylvan have proposed a reformulation which eschews the (...) need for normative representation (Lord and Sylvan 2019 [“Prime Time (for the Basing Relation).” In Well-Founded Belief, edited by J. Adam Carter, and Patrick Bondy, 141–173. London and New York: Routledge]). As they argue, agents must treat their motivating reasons as normative reasons, where this notion picks out a specific set of dispositions rather than a representational state. I argue that this proposal seriously distorts our understanding of the relation between an action or attitude and the reasons for which we perform or hold it. On the plausible assumption that an account of motivating reasons should not stray too far from this understanding, this response to the over-demandingness charge thus fails. I also provide some directions on how friends of the Taking Condition should instead respond this charge. (shrink)

This thesis investigates the nature of the relation between mental representations in successful verbal communication, thought attribution, agreement, and disagreement — a relation which I call “samethinking”. The nature of samethinking raises several foundational questions about the nature of (non-natural) meaning, and the cognitive underpinnings of the emergence of culture. It bears on long-lasting puzzles in the philosophy of mind and language (such as Frege’s puzzle and Kripke’s puzzle about belief). Samethinking does not amount to sharing a reference (with “sharing" (...) I refer to two or more thinkers having something in common): it is more demanding. How can we explain and characterize this relation, more stringent than coreference, that is instantiated by a pair of thoughts when samethinking takes place? It is often assumed that this relation involves sharing a thought content more fine-grained than reference. In this thesis, I argue that the issue is more complex than what has been commonly assumed, and I suggest an alternative model in which sharing thought content is not necessary. (shrink)

According to the standard view, a belief is based on a reason and doxastically justified—i.e., permissibly held—only if a causal relation obtains between a reason and the belief. In this paper, I argue that a belief can be doxastically justified by a reason’s mere disposition to sustain it. Such a disposition, however, wouldn’t establish a causal connection unless it were manifested. My argument is that, in the cases I have in mind, the manifestation of this disposition would add no positive (...) epistemic feature to the belief: a belief that is justified after the manifestation of a reason’s causal powers must have already been justified before their manifestation. As a result, those who adhere to the standard causal view of the basing relation face a hard choice: they should either abandon the enormously popular view that doxastic justification has a basing requirement or modify their view of the basing relation. (shrink)

Taking perceptual experience to consist in a relation of acquaintance with the sensible qualities, I argue that the state of being acquainted with a sensible quality is intrinsically a form of knowledge, and not merely a means to more familiar kinds of knowledge, such as propositional or dispositional knowledge. We should accept the epistemic claim for its explanatory power and theoretical usefulness. That acquaintance is knowledge best explains the intuitive epistemic appeal of ‘Edenic’ counterfactuals involving unmediated perceptual contact with reality (...) (cf. Chalmers, in: Gendler, Hawthorne (eds) Perceptual experience, Oxford University Press, 2006). It explains the elusiveness of knowledge gained through new acquaintances. It coheres with the knowledge-like functional role of acquaintance in the special context of evaluative beliefs and evaluative reasoning, where the objects of acquaintance serve as evidence and inferential basis. And, finally, taking acquaintance to be knowledge is theoretically fruitful: it helps vindicate claims about the relationship between knowledge and concern for others we already find intuitive or outright accept. After developing a novel case for the epistemic claim, I respond to two familiar objections against it: namely, (1) that there are no pre-propositional, pre-conceptual cases of perceptual experience that remain epistemically relevant (Sellars in Empiricism and the philosophy of mind, Routledge, 1968, McDowell, in: Lindgard (ed) John McDowell: Experience, norm, and nature, Blackwell, 2008); and (2) that the category of knowledge appears gerrymandered once we add ‘object’ knowledge to the epistemological mix (Farkas, in: Knowles, Raleigh (eds), Acquaintance: new essays, Oxford University Press, 2019). (shrink)

To be acquainted with something (in the philosophical sense of “acquainted” discussed here) is to be directly aware of it. The idea that we are acquainted with certain things we experience has been discussed throughout the history of Western Philosophy, but in the early 20th century it gained especially focused attention among analytic philosophers who drew their inspiration from Bertrand Russell's work on acquaintance. Since then, many philosophers—particularly those working on self‐knowledge or perception—have used the notion of acquaintance to explain (...) various facts about human experience and knowledge. In this paper, I offer an overview of this work, with particular focus on the resurgent literature on acquaintance in contemporary analytic philosophy. After more fully explaining what acquaintance is (or is supposed to be), I describe some reasons for thinking that we are indeed acquainted with certain things we experience, and then I survey some of the facts about experience and knowledge that acquaintance may help explain.

There are many important dimensions of epistemic evaluation, one of which is justification. We don’t just evaluate beliefs for truth, reliability, accuracy, and knowledge, but also for justification. However, in the epistemological literature, there is much disagreement about the nature of justification and how it should be understood. One of the controversies that has separated the contemporary epistemological discourse into two opposing camps has to do with the internalism-externalism distinction. Whereas internalists defend certain core assumptions about justification from the pre-Gettier (...) tradition, externalists generally think that the traditional conception is untenable and should be replaced. In this compilation thesis, I argue for, defend, and develop a particular brand of internalism, both in general and with respect to specific sources of justification. In papers 1 and 2, I defend a couple of well-known arguments for mentalism and accessibilism. Moreover, I also point out how prominent versions of these theses are vulnerable to serious problems (e.g., about over-intellectualization and vicious regresses). Part of my goal in the first couple of papers is to figure out what commitments the internalist should take on in order to avoid the externalist's objections, while at the same time receiving support from considerations that have motivated internalism in the past. In papers 3 and 4, I start from the assumption that mentalism is true and attempt to answer the following questions: 1) which non-factive mental states can play a justification-conferring role with respect to empirical belief? And 2) why does this set of states play the epistemic role it does? In response to question 1, I argue that all and only one's beliefs and perceptual experiences have justificatory relevance. In response to question 2, I argue that one's beliefs and perceptual experiences are one's strongly representational states, and that strongly representational states necessarily provide support to certain empirical propositions. Having done so, I then defend mentalism about scientific evidence from a couple of prominent objections in the recent literature. Lastly, in papers 5 and 6, I argue for a particular brand of internalism about testimonial and memorial justification and show how that position has a dialectical advantage over its main competitors. (shrink)

A common response to radical skeptical challenges to our knowledge of the external world has been that there are explanatory reasons (e.g., simplicity, coherence, explanatory power, conservatism) for favoring commonsense explanations of our sensory experiences over skeptical explanations. Despite the degree of visibility this class of response has enjoyed, it has often been viewed with skepticism [sic] by the epistemological community because of concerns about the epistemic merits of explanatory reasoning. I argue that skeptical challenges that employ skeptical hypotheses presuppose (...) central explanationist tenets and that this fact should raise one’s estimation of the strength of explanationist responses to skepticism.

According to a traditional picture, perception and belief have starkly different epistemic roles. Beliefs have epistemic statuses as justified or unjustified, depending on how they are formed and maintained. In contrast, perceptions are “unjustified justifiers.” Core cognition is a set of mental systems that stand at the border of perception and belief, and has been extensively studied in developmental psychology. Core cognition's borderline states do not fit neatly into the traditional epistemic picture. What is the epistemic role of these states? (...) Focusing on the core object system, the author argues that core object representations have epistemic statuses like beliefs do, despite their many prototypically perceptual features. First, the author argues that it is a sufficient condition on a mental state's having an epistemic status as justified or unjustified that the state is based on reasons. Then the author argues that core object representations are based on reasons, through an examination of both experimental results and key markers of the basing relation. The scope of mental states that are subject to epistemic evaluation as justified or unjustified is not restricted to beliefs. (shrink)

Empirical work on motivated reasoning suggests that our judgments are influenced to a surprising extent by our wants, desires and preferences (Kahan 2016; Lord, Ross, and Lepper 1979; Molden and Higgins 2012; Taber and Lodge 2006). How should we evaluate the epistemic status of beliefs formed through motivated reasoning? For example, are such beliefs epistemically justified? Are they candidates for knowledge? In liberal democracies, these questions are increasingly controversial as well as politically timely (Beebe et al. 2018; Lynch forthcoming, 2018; (...) Slothuus and de Vreese 2010). And yet, the epistemological significance of motivated reasoning has been almost entirely ignored by those working in mainstream epistemology. We aim to rectify this oversight. Using politically motivated reasoning as a case study, we show how motivated reasoning gives rise to three distinct kinds of skeptical challenges. We conclude by showing how the skeptical import of motivated reasoning has some important ramifications for how we should think about the demands of intellectual humility. (shrink)

The primary aim of this paper is to defend the Lockean View—the view that a belief is epistemically justified iff it is highly probable—against a new family of objections. According to these objections, broadly speaking, the Lockean View ought to be abandoned because it is incompatible with, or difficult to square with, our judgments surrounding certain legal cases. I distinguish and explore three different versions of these objections—The Conviction Argument, the Argument from Assertion and Practical Reasoning, and the Comparative Probabilities (...) Argument—but argue that none of them are successful. I also present some very general reasons for being pessimistic about the overall strategy of using legal considerations to evaluate epistemic theories; as we will see, there are good reasons to think that many of the considerations relevant to legal theorizing are ultimately irrelevant to epistemic theorizing.

In Lehrer’s case of the superstitious lawyer, a lawyer possesses conclusive evidence for his client’s innocence, and he appreciates that the evidence is conclusive, but the evidence is causally inert with respect to his belief in his client’s innocence. This case has divided epistemologists ever since Lehrer originally proposed it in his argument against causal analyses of knowledge. Some have taken the claim that the lawyer bases his belief on the evidence as a data point for our theories to accommodate, (...) while others have denied that the lawyer has knowledge, or that he bases his belief on the evidence. In this paper, we move the dialectic forward by way of arguing that the superstitious lawyer genuinely infers his client’s innocence from the evidence. To show that the lawyer’s inference is genuine, we argue in defense of a version of a doxastic construal of the ‘taking’ condition on inference. We also provide a pared-down superstitious lawyer-style case, which displays the key features of the original case without including its complicated and distracting features. But interestingly, although we argue that the lawyer’s belief is based on his good evidence, and is also plausibly doxastically justified, we do not argue that the lawyer knows that his client is innocent.

In her black and white room, Mary doesn’t know what it is like to see red. Only after undergoing an experience as of something red and hence acquainting herself with red can Mary learn what it is like. But learning what it is like to see red requires more than simply becoming acquainted with it. To be acquainted with something is to know it, but such knowledge, as we argue, is object-knowledge rather than propositional-knowledge. To know what it is like (...) one must know an appropriate propositional answer to the question ‘what is it like?’. Despite this mismatch between object-knowledge and knowing an answer, we believe that acquaintance is crucial to Mary’s epistemic progress. When Mary leaves her black and white room, her new knowledge tempts one to think that she must come to know a candidate answer (a coarse-grained fact) that she didn’t know in her room. Since Mary already knows all the physical facts in her room, any additional facts she might learn appear to threaten physicalism. In reply, many physicalists have been attracted to the phenomenal concept strategy according to which Mary can come to have new knowledge and hence know a new answer to the question ‘what is it like to see red?’ by entertaining a coarse-grained fact under a concept she didn’t possess in her room – Mary learns a new fine-grained fact. We believe both of these accounts of Mary’s epistemic progress are mistaken. As we argue, Mary could know every fact (coarse-grained and fine-grained) that might serve as an answer to the question ‘what is it like to see red?’ and still not know what it is like. The physical world leaves no leftover coarse-grained facts for Mary to learn and because concepts are sharable, easy to possess, and easy to introduce, there are possible situations in which Mary, while in her black and white room, has every concept that might make a fine-grained difference. In short, even when Mary is granted a great deal of factual knowledge and vast conceptual resources, she may still not know an appropriate answer to the question ‘what is it like to see red?’. But in any such situation, Mary lacks acquaintance with red and on this basis we argue that in order to know what it is like, in order for Mary to know an appropriate answer, Mary’s propositional knowledge must be appropriately related to her acquaintance with red.

In a paper and a reply to critics published in _Informal Logic_, I argue that arguments from expert opinion are weak arguments. To appeal to expert opinion is to take an expert’s judgment that _p_ is the case as evidence for _p_. Such appeals to expert opinion are weak, I argue, because the fact that an expert judges that _p_ does not make it significantly more likely that _p_ is true or probable, as evidence from empirical studies on expert performance (...) suggests. Unlike other critics of this argument, who take issue with the empirical evidence on expert performance, David Botting says that he wants to take issue with the premise that reliability is a necessary condition for the strength of appeals to expert opinion. I respond to Botting’s objections and argue that they miss their intended target. I also argue that his attempt to show that arguments from expert opinion are strong is unsuccessful. (shrink)

The article discusses infinitism, the view that a belief is justified for a subject only if she possesses an infinite chain of available reasons for that belief. In its most recent and sophisticated version, the view allegedly escapes the problems that trouble its main competitors, foundationalism and coherentism, while avoiding the traditional objections which relegated it to a marginal place. The article argues that despite these improvements, sophisticated versions of infinitism face a pressing problem, viz. they are unable to appropriately (...) articulate propositional and doxastic justification.
