Propositional and Doxastic Justification

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)

As George Boole saw it, the laws of logic are the laws of thought, and by this he meant, not that human thought is actually governed by the laws of logic, but, rather, that it should be. Boole’s view that the laws of logic have normative implications for how we ought to think is anything but an outlier. The idea that violating the laws of logic involves epistemic impropriety has seemed to many to be just obvious. It has seemed especially (...) obvious to those who see propositional justification as more fundamental than doxastic justification. Whatever other principles are required for defining propositional justification, the laws of logic seem indispensable. The idea that violation of the laws of logic involves some sort of epistemic impropriety—whatever the peculiarities of our psychology may be—has served as a fixed point around which defenders of the fundamentality of propositional justification are united, whatever their other differences. This paper challenges that common thread in defenses of the fundamentality of propositional justification. It is argued that the laws of logic have no bearing whatever on epistemic justification. Once we see why this should be so, the way is paved for seeing why it is that doxastic justification is more fundamental than propositional justification. (shrink)

By justification we understand what makes a belief epistemologically viable: generally this is considered knowledge that is true. The problem is defining this with a higher degree of precision because this is where different conflicting conceptions appear. On the one hand, we can understand justification as what makes it reasonable to acquire or maintain a belief; on the other, it is what increases the probability that the belief is true. This work tries to prove that beliefs depend on other beliefs (...) that are epistemically justified and that such beliefs are the result of (i.e., they arise from) our privileged intuition of reality. For this, we examine the concept of epistemic regress. Epistemic reasons authorize a proposition P to be the conclusion of an argument in which such reasons function as premises and are vulnerable to epistemic regress. The three most important approaches to epistemic regress are Infinitism, Coherentism and Foundationalism. (shrink)

I argue that a general feature of human psychology provides strong reason to modify or reject anti-reductionism about the epistemology of testimony. Because of the work of what I call “the background” (which is a collection of all of an individual's synthetizations, summarizations, memories of experiences, beliefs, etc.) we cannot help but form testimonial beliefs on the basis of a testifier's say so along with additional evidence, concepts, beliefs, and so on. Given that we arrive at testimonial beliefs through the (...) work of the background, to be justified in holding a testimonial belief, we must not only have a rational speaker's say so, but we must also form such beliefs in a right way. If this is right, then, contrary to typical anti-reductionism, justified testimonial beliefs require more than just a trustworthy testifier's say so – another requirement is that they are formed in a right way.

In this paper, I explore how the ideal rationality-based account of propositional justification impacts our understanding of the relation between propositional and doxastic justification. The ideal rationality-based account sits uncomfortably with the widely accepted claim that propositional justification is necessary for doxastic justification. In particular, the combination of the necessity claim and the ideal rationality-based account of propositional justification entails that some plausible doxastic attitudes are doxastically unjustified and thereby severs epistemic justification from connections with epistemic responsibility and the competent (...) formation of beliefs. Thus, those who endorse both the necessity claim and the ideal rationality-based account of propositional justification will be forced to give up either their account of propositional justification or the necessity claim. I argue that there is good reason to give up the ideal rationality-based account of propositional justification instead of the necessity claim. This result indicates that an adequate account of propositional justification should be sensitive to the agent’s cognitive capacities. If propositional justification should be understood in this way, then the widely accepted explanation of doxastic justification in terms of propositional justification is not promising either. This is because an agent’s cognitive capacities and limitations play a prominent role in understanding propositional justification. Instead, I argue that, at the explanatory level, propositional justification relies on doxastic justification. (shrink)

One emerging issue in contemporary epistemology concerns the relation between animal knowledge, which can be had by agents unable to take a view on the epistemic status of their attitudes, and reflective knowledge, which is only available to agents capable of taking such a view. Philosophers who are open to animal knowledge often presume that while many of the beliefs of human adults are formed unreflectively and thus constitute mere animal knowledge, some of them—those which become subject of explicit scrutiny (...) or are the result of a deliberative effort—may attain the status of reflective knowledge. According to Sanford Goldberg and Jonathan Matheson (2020), however, it is impossible for reflective subjects to have mere animal knowledge. If correct, their view would have a number of repercussions, perhaps most notably the vindication of a dualism about knowledge, which would frustrate attempts to provide a unified account of knowledge-attributions to human adults, very young children, and non-human animals. I discuss Goldberg and Matheson’s proposal, outline some of the ways in which it is insightful, and argue that it is ultimately unsuccessful because it neglects the inherent temporal dimension of knowledge acquisition. While the article is pitched as a reply to Goldberg and Matheson, its primary aim is to highlight significant connections between the debates on the relation between animal and reflective knowledge, propositional and doxastic justification, and the theory of epistemic defeat.

There is a difference between having reasons for believing and believing for reasons. This difference is often fleshed out via an epistemic basing relation, where an epistemic basing relation obtains between beliefs and the actual reasons for which those beliefs are held. The precise nature of the basing relation is subject to much controversy, and one such underdeveloped issue is whether beliefs can be based on brain processing. In this paper I answer in the negative, providing reasons that the basing (...) relation must be a specific psychological level relation between mental states, rather than being a brain process.

The distinction between propositional and doxastic justification is well-known among epistemologists. Propositional justification is often conceived as fundamental and characterized in an entirely apsychological way. In this chapter, I focus on beliefs based on deductive arguments. I argue that such an apsychological notion of propositional justification can hardly be reconciled with the idea that justification is a central component of knowledge. In order to propose an alternative notion, I start with the analysis of doxastic justification. I then offer a notion (...) of propositional justification, intersubjective propositional justification, that is neither entirely apsychological nor idiosyncratic. To do so, I argue that to be able to attribute propositional justification to a subject, we have to consider her social context as well as broad features of our human cognitive architecture.

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

The distinction between propositional and doxastic justification is normally applied to belief. The goal of this paper is to apply the distinction to faith and hope. Before doing so, I discuss the nature of faith and hope, and how they contrast with belief—belief has no essential conative component, whereas faith and hope essentially involve the conative. I discuss implications this has for evaluating faith and hope, and apply this to the propositional/doxastic distinction. There are two key upshots. One, bringing in (...) faith and hope makes salient additional normative categories, including the way the distinction between epistemic and practical justification interacts with the distinction between propositional and doxastic justification. Two, a paradigm example of propositional without doxastic justification is a belief that is evidentially supported but based on wishful thinking. Surprisingly, parallel cases of faith and hope may actually enjoy both propositional and doxastic justification. I conclude by exploring what it might look like for faith and hope to have propositional justification without doxastic justification. (shrink)

In response to the claim that certain epistemically defective inferences such as Moore’s argument lead us to the conclusion that we ought to abandon closure, Crispin Wright suggests that we can avoid doing so by distinguishing it from a stronger principle, namely transmission. Where closure says that knowledge of a proposition is a necessary condition on knowledge of anything one knows to entail it, transmission makes a stronger claim, saying that by reasoning deductively from known premises one can thereby acquire (...) knowledge of or justification for the conclusion. Wright’s thought is that in cases such as Moore what is really going on is a failure of transmission, not a failure of closure. The problem with this claim is that it relies on an outdated formulation of closure which few nowadays would find plausible. Once we stipulate that it is the intuitive closure principle that deserves our attention, it becomes far less obvious that the project of diagnosing what is wrong with arguments such as Moore in terms of transmission failure but not closure failure can be vindicated. In order to demonstrate this claim, I consider intuitive closure of propositional justification vs. transmission of propositional justification and concede that perhaps these can come apart in the way that Wright suggests. I then argue that despite this concession, we also need an answer to the question of whether intuitive closure for doxastic justification and transmission for doxastic justification can come apart. We need an answer to this question because our ultimate interest in these issues stems from our interest in whether knowledge obeys closure, not merely whether propositional justification does. I argue that, even on the assumption that there is transmission failure of propositional justification, there is no transmission failure of doxastic justification. And if this is true, then there is no transmission failure of knowledge either. The transmission failure diagnosis of Moore’s argument and its ilk is thus in trouble. (shrink)

My starting point is what I call the Normative Authority Conception of justification, where S is justified in their belief that p at t (to some degree n) if and only if their believing that p at t is not ruled out by epistemic norms that have normative authority over S at t. With this in mind, this paper develops an account of doxastic justification by first developing an account of the normative authority of epistemic norms. Drawing from work in (...) political philosophy, I argue that (a) the cognitive and evaluative commitments and concerns behind our actual practices of holding each other and ourselves accountable for our beliefs reveal which epistemic norms we have consented to be under, and that (b) it is because we have consented to be under the authority of these norms – by actually holding ourselves and others accountable to them – that they in turn have normative authority over us. By connecting the authority of epistemic norms to the authority we have over ourselves in this way, the resulting account of doxastic justification (i) explains why it can be appropriate to criticize, resent, or sanction someone for having unjustified beliefs, (ii) avoids the phenomena of normative alienation and normative parochialism, and (iii) respects the social and collective nature of epistemic justification.

In his book The Intellectual Virtues and the Life of the Mind: On the Place of the Virtues in Contemporary Epistemology, Jonathan Kvanvig argues that there is an interchangeability of personal and doxastic justification, which ‘blocks the quick route to virtue epistemology’. To prove that personal justification is reducible to doxastic justification, he utilizes λ-calculus expressions that aim to show the logical equivalence of the two notions of justification. In this paper, I argue that he has made an illegitimate move (...) in his translation of the ordinary talk of personal justification into λ-expressions because his translation involves both an elimination from and an addition to the ordinary language. Pace Kvanvig, there is no logical equivalence of personal to doxastic justification. So, his argument for the reducibility of personal to doxastic justification founders. More importantly, since he has failed to disprove that personal justification is irreducibly primitive, he hasn’t shown that the prospects for virtue epistemology are ‘hopeless’. (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)

The basing demand on doxastic justification is a widely held and highly intuitive dogma of contemporary epistemology. In Silva [2015, AJP], I argued that the dialectical significance of this dogma is severely limited by our lack of independent grounds for endorsing it. Oliveira [2015, AJP] sought to defend the basing demand on doxastic justification. Here I explain why Oliveira’s attempted defense of the basing demand misses its mark. I also briefly suggest that there is an alternative way of defending the (...) basing demand. The alternative way is reconciliatory: it shows that most epistemologists may have been right to insist on such a demand, but perhaps still wrong to treat it as a dialectically powerful tool in the assessment of certain substantive epistemological theories.

The distinction between propositional and doxastic justification has been of undisputed theoretical importance in a wide range of contemporary epistemological debates. Yet there are a host of intimately related issues that have rarely been discussed in connection with this distinction. For instance, the distinction not only applies to an individual’s beliefs, but also to group beliefs and to various other attitudes that both groups and individuals can take: credence, commitment, suspension, faith, and hope. Moreover, discussions of propositional and doxastic justification (...) have rarely focused on broader meta-epistemological issues, and yet meta-epistemological positions can have important implications for first-order views about this distinction. This volume addresses these and other issues by bringing together 16 essays that advance the state-of-the-art thinking on propositional and doxastic justification and explore how such thinking shapes and is shaped by a range of issues previously neglected in contemporary epistemology.

This chapter is concerned with the distinction that most contemporary epistemologists express by distinguishing between “propositional” and “doxastic” justification. The goal is to develop an account of this distinction that applies, not just to full or outright beliefs, but also to partial credences—and indeed, in principle, to attitudes of all kinds. The standard way of explaining this distinction, in terms of the “basing relation”, is criticized, and an alternative account—the “virtue manifestation” account—is proposed in its place. This account has a (...) certain kinship with the epistemological approach that is known as “reliabilism”, but it also has certain key differences—above all, it is compatible with an internalist view of rationality.

I submit that the critical epistemology of race and standpoint literature has not explicitly focused on the properties of information about, say, racial or gender injustice in a way similar to how epistemologists have focused on propositions and information when they describe propositional justification. I describe information in the racial-injustice-information domain in a way similar to how epistemologists describe propositional justification. To this end, I argue (C1) that if subjects in racially unjust societies tend to violate norms that promote a (...) community’s reliable information flow because racial prejudice is widely held in racially unjust societies, then racial injustice can make information flow less reliably in a community. I also argue (C2) that if racial prejudice can make information flow less reliably in a community, then information that non-dominant subjects are more likely to have will less reliably flow to community members who lack it.

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

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

It is clear that beliefs can be assessed both as to their justification and their rationality. What is not as clear, however, is how the rationality and justification of belief relate to one another. Stewart Cohen has stumped for the popular proposal that rationality and justification come to the same thing, that rational beliefs just are justified beliefs, supporting his view by arguing that ‘justified belief’ and ‘rational belief’ are synonymous. In this paper, I will give reason to think that (...) Cohen’s argument is spurious. I will show that ‘rational’ and ‘justified’ occupy two distinct semantic categories – ‘rational’ is an absolute gradable adjective and ‘justified’ is a relative gradable adjective – telling against the thought that ‘rational belief’ and ‘justified belief’ are synonymous. I will then argue that the burden of proof is on those who would equate rationality and justification, making the case that those who hold this prominent position face the difficulty of explaining how rationality and justification come to the same thing even though ‘rational’ and ‘justified’ are not synonymous.

Doxastic Conservatism We are creatures with clear cognitive limitations. Our memories are finite and there is a limit to the kinds of things we can store and retrieve.

This paper examines two objections to the infinitist theory of epistemic justification, namely “the finite mind objection” and “the distinction objection.” It criticizes Peter Klein’s response to the distinction objection and offers a more plausible response. It is then argued that this response is incompatible with Klein’s response to the finite mind objection. Infinitists, it would seem, cannot handle both objections when taken together.

Las afirmaciones verdaderas reciben su justificación de creencias que tienen al conocimiento como base, por lo que para su formulación y comprensión se necesita asumir una posición fundacionalista.

A diferencia de Goldman, considero que no todas las creencias tienen que ser verdaderas, ni toda justificación de las creencias requiere de la verdad.

ABSTRACTAccording to epistemic internalists, facts about justification supervene upon one's internal reasons for believing certain propositions. Epistemic externalists, on the other hand, deny this. More specifically, externalists think that the supervenience base of justification isn't exhausted by one's internal reasons for believing certain propositions. In the last decade, the internalism–externalism debate has made its mark on the epistemology of testimony. The proponent of internalism about the epistemology of testimony claims that a hearer's testimonial justification for believing that p supervenes upon (...) his internal reasons for thinking that the speaker's testimony that p is true. Recently, however, several objections have been raised against this view. In this paper, I present an argument providing intuitive support for internalism about the epistemology of testimony. Moreover, I also defend the argument against three recent objections offered by Stephen Wright in a couple of recent papers. The upshot of my discussion is that external conditions do make an epistemic difference when it comes to our testimonial beliefs, but that they cannot make any difference with respect to their justificatory status – i.e., they are justificationally irrelevant.

Rosenkranz has recently proposed a logic for propositional, non-factive, all-things-considered justification, which is based on a logic for the notion of being in a position to know, 309–338 2018). Starting from three quite weak assumptions in addition to some of the core principles that are already accepted by Rosenkranz, I prove that, if one has positive introspective and modally robust knowledge of the axioms of minimal arithmetic, then one is in a position to know that a sentence is not provable (...) in minimal arithmetic or that the negation of that sentence is not provable in minimal arithmetic. This serves as the formal background for an example that calls into question the correctness of Rosenkranz’s logic of justification. (shrink)

This book is concerned with the conditions under which epistemic reasons provide justification for beliefs. The author draws on metaethical theories of reasons and normativity and then applies his theory to various contemporary debates in epistemology. In the first part of the book, the author outlines what he calls the dispositional architecture of epistemic reasons. The author offers and defends a dispositional account of how propositional and doxastic justification are related to one another. He then argues that the dispositional view (...) has the resources to provide an acceptable account of the notion of the basing relation. In the second part of the book, the author examines how his theory of epistemic reasons bears on the issues involving perceptual reasons. He defends dogmatism about perceptual justification against conservatism and shows how his dispositional framework illuminates certain claims of dogmatism and its adherence to justification internalism. Finally, the author applies his dispositional framework to epistemological topics including the structure of defeat, self-knowledge, reasoning, emotions and motivational internalism. The Dispositional Architecture of Epistemic Reasons demonstrates the value of employing metaethical considerations for the justification of beliefs and propositions. It will be of interest to scholars and advanced students working in epistemology and metaethics. (shrink)

This is the Editor's Introduction to "Well-Founded Belief: New Essays on the Epistemic Basing Relation" (Routledge, 2020).

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.

Turri argues against what he calls an “orthodox” view of the relationship between propositional and doxastic justification, according to which (Basis) it is sufficient for S to be doxastically justified in believing p that p is propositionally justified for S in virtue of having reason(s) R and S believes p on the basis of R. According to Turri, (Basis) is false and hence the orthodox view is wrong. Turri offers “an alternative proposal,” the definitive thesis of which is that the (...) subject’s intellectual abilities explain why a given proposition, p, is justified for her, and argues that, contra the orthodoxy, this proposal leads to explaining propositional justification in terms of doxastic justification rather than vice versa. In this paper, I argue for the following claims: (i) There are good reasons to think that Turri misidentifies “the orthodox view” and his objection thereby misfires, (ii) Even if we assume that Turri’s identification of the orthodox view is correct, his counter-examples to that view are far from being decisive, and (iii) Turri’s own proposal is not “an alternative” to the orthodox view but can be accommodated by it.

Facts about justification are not brute facts. They are epistemic facts that depend upon more fundamental non-epistemic facts. Internalists about justification often argue for mentalism, which claims that facts about justification supervene upon one’s non-factive mental states, using Lehrer and Cohen’s :191–207, 1983) New Evil Demon Problem. The New Evil Demon Problem tells you to imagine yourself the victim of a Cartesian demon who deceives you about what the external world is like, and then asks whether you nevertheless have justification (...) for your beliefs about the external world. Internalists and externalists agree that there is something that is epistemically good or valuable about both your actual beliefs and your beliefs in the demon scenario. Internalists claim that the epistemic property which these sets of beliefs share most intuitively should be thought of as sameness of justification. Externalists, on the other hand, reject this claim, usually either by challenging the internalist intuition directly, or by arguing that there is a more plausible way to think about the epistemic property in question. Recently, both kinds of externalist objection have been raised against the argument from the New Evil Demon Problem for mentalism. The goal of this paper is to defend the argument against three prominent objections—a pair of which is offered by Littlejohn :399–434, 2009) and one by Williamson Rationality and the good: critical essays on the ethics and epistemology of Robert Audi, Oxford University Press, Oxford, 2007; in: Dutant J, Dohrn D The new evil demon, Oxford University Press, Oxford, 2016).

Process reliabilism is a theory about ex post justification, the justification of a doxastic attitude one has, such as belief. It says roughly that a justified belief is a belief formed by a reliable process. It is not a theory about ex ante justification, one’s justification for having a particular attitude toward a proposition, an attitude one might lack. But many reliabilists supplement their theory such that it explains ex ante justification in terms of reliable processes. In this paper I (...) argue that the main way reliabilists supplement their theory fails. In the absence of an alternative, reliabilism does not account for ex ante justification. (shrink)

The standard reliabilist line on defeat is open to counterexamples regarding its necessity and sufficiency. In this paper, I present three problems for the standard reliabilist line from the recent literature on defeat before arguing that reliabilists can solve those problems by adopting an account of justification that ties defeat to the evidence possessed by the relevant agent. In doing so, I show that there is a conception of having evidence that reliabilists can adopt without giving up on the core (...) commitments of their research program, namely the reduction of epistemic facts and having a psychologically realistic account of justification. My account of defeat draws on the account of propositional justification, transglobal evidentialism, defended by David Henderson, Terry Horgan, and Matjaž Potrč. (shrink)

My thesis, which I call the phenomenal basing thesis, is that the evidential basing relation obtains between someone’s belief and evidence E only if the mental state associated with E has phenomenal character. In §2, I explain the thesis and provide background. In §3–§6, I show that the phenomenal basing thesis holds for simple basic beliefs, inferential beliefs, and complex basic beliefs, both when the beliefs are being formed and when they are being sustained.

A subject S's belief that Q is well-grounded if and only if it is based on a reason of S that gives S propositional justification for Q. Depending on the nature of S's reason, the process whereby S bases her belief that Q on it can vary. If S's reason is non-doxastic––like an experience that Q or a testimony that Q––S will need to form the belief that Q as a spontaneous and immediate response to that reason. If S's reason (...) is doxastic––like a belief that P––S will need to infer her belief that Q from it. The distinction between these two ways in which S's beliefs can be based on S's reasons is widely presupposed in current epistemology but––we argue in this paper––is not exhaustive. We give examples of quite ordinary situations in which a well-grounded belief of S appears to be based on S's reasons in neither of the ways described above. To accommodate these recalcitrant cases, we introduce the notion of enthymematic inference and defend the thesis that S can base a belief that Q on doxastic reasons P1, P2, …, Pn via inferring enthymematically Q from P1, P2, …, Pn.

According to the Path Principle, it is permissible to expand your set of beliefs iff (and because) the evidence you possess provides adequate support for such beliefs. If there is no path from here to there, you cannot add a belief to your belief set. If some thinker with the same type of evidential support has a path that they can take, so do you. The paths exist because of the evidence you possess and the support it provides. Evidential support (...) grounds propositional justification. -/- The principle is mistaken. There are permissible steps you may take that others may not even if you have the very same evidence. There are permissible steps that you cannot take that others can even if your beliefs receive the same type of evidential support. Because we have to assume almost nothing about the nature of evidential support to establish these results, we should reject evidentialism. (shrink)

One important distinction in the debate over the nature of epistemic justification is the one between propositional and doxastic justification. Roughly, while doxastic justification is a property of beliefs, propositional justification is a property of propositions. On a rather common view, which accounts for doxastic justification in terms of propositional justification plus the so-called ‘basing relation’, propositional justification is seen as the prior notion, and doxastic justification is explained in terms of it. According to the opposing view, the direction of (...) explanation needs to be reversed, and doxastic justification should be seen as primary. I distinguish between two notions of priority, and I argue that they give different verdicts with respect to the issue of which notion of justification comes first. The lesson may be taken to be that propositional and doxastic justification are in a relation of intertwinement. (shrink)

The purpose of this paper is to challenge what is often called the “Uniqueness” thesis. According to this thesis, given one’s total evidence, there is a unique rational doxastic attitude that one can take to any proposition. It is sensible for defenders of Uniqueness to commit to an accompanying principle that: when some agent A has equal epistemic reason both to believe that p and to believe that not p, the unique epistemically rational doxastic attitude for A to adopt with (...) respect to whether p is the suspension of judgment. In this paper, I offer a case wherein the agent has equal epistemic reason both to believe that p and to believe that not p, but the agent is not epistemically required to suspend judgment about whether p. Furthermore, the case is such that there seems to be no uniquely rational attitude for the agent to adopt. (shrink)

Epistemologists focus primarily on cases of knowledge, belief, or credence where the evidence which one possesses, or on which one is relying, plays a fundamental role in the epistemic or normative status of one's doxastic state. Recent work in epistemology goes beyond the evidence one possesses to consider the relevance for such statuses of evidence which one does not possess, particularly when there is a sense in which one should have had some evidence. I focus here on Sanford Goldberg's approach (...)

Ordinarily, people take themselves to know a lot. I know where I was born, I know that I have two hands, I know that two plus two equals four, and I also think I know a lot of other stuff too. However, the project of trying to provide a philosophically satisfying account of knowledge, one that holds up against skeptical challenges, has proven surprisingly difficult. Either one aims for an account of justification (and knowledge) that is epistemologically demanding, in an (...) effort to offer an account that satisfactorily addresses skepticism, or one aims for an account of justification (and knowledge) that makes sense of our ordinary knowledge claims. However, the history of contemporary epistemology tells us that you cannot have both: the former results in skepticism, the latter in an unsatisfying response to skepticism. -/- What we find, in the array of contemporary attempts to give accounts of knowledge and justification, are numerous views spread across the internalism/externalism spectrum that deal with the dilemma of the previous paragraph in different ways. Most of them are guided by the goal of accommodating our ordinary knowledge claims. This is especially true of externalist accounts, but many internalist accounts are guided by this same goal, though perhaps to a lesser degree. One kind of internalist view stands out for its insistence on providing philosophically satisfying accounts of knowledge and justification, even if doing so has skeptical implications. This is the traditional, old-fashioned, Cartesian-style internalism that was so prominent in the early 20th century and is now a minority position. -/- Unlike competing versions of epistemic internalism, the guiding principle of traditional, Cartesian-style internalism (what I will henceforth call ‘traditional internalism’) is not to accommodate our commonsense views about the rationality of our ordinary beliefs. Instead, traditional internalism emphasizes rationality’s demand for philosophical assurance, on the basis of evidence that can withstand the strongest skeptical challenges, that our ordinary beliefs (perceptual and otherwise) are true. According to the traditional internalist, the philosopher, qua philosopher, ought to begin the epistemological project from the inside, placing a premium on satisfying our philosophical curiosity. -/- Despite the relative unpopularity of traditional internalism the view can be taken to be worthy of attention for a variety of reasons. First, traditional internalism has great historical importance. Significant portions of the history of contemporary epistemology, and to a lesser degree philosophy in the modern era (roughly, Descartes to Kant), are grounded in a number of the intuitions that drive traditional internalism. Second, and perhaps even more importantly, traditional internalism serves as the source of a wide variety of criticisms for other, more prominent, contemporary epistemological views. In a number of debates the views of the traditional internalist are used to play a kind of Devil’s advocate. Finally, some of the ideas that ground traditional internalism have had a bit of resurgence of late.1 To put it simply, traditional internalism refuses to go away. In this introduction, I will do three things. First, I will situate traditional internalism among other competing versions of internalism by highlighting the ways in which traditional internalism differs from them (in particular, evidentialism and conservatism). Second, I will explain more carefully some of the central tenets of traditional internalism and what motivates them. Third, I will highlight some of the difficulties that threaten traditional internalism, and I will explain how the contributions to this volume interact with those difficulties. -/- The goal of this volume is to test again the staying power of traditional internalism, to see if this once historically prominent view deserves another look, to see if traditional internalism is a legitimate contender providing useful criticisms of more prominent views, or, if instead it is time for traditional internalism to be left by the wayside.

Elsewhere I and others have argued that evidence one should have had can bear on the justification of one's belief, in the form of defeating one's justification. In this paper, I am interested in knowing how evidence one should have had (on the one hand) and one's higher-order evidence (on the other) interact in determinations of the justification of belief. In doing so I aim to address two types of scenario that previous discussions have left open. In one type of (...) scenario, there is a clash between a subject's higher-order evidence and the evidence she should have had: S's higher-order evidence is misleading as to the existence or likely epistemic bearing of further evidence she should have. In the other, while there is further evidence S should have had, this evidence would only have offered additional support for S's belief that p. The picture I offer derives from two “epistemic ceiling” principles linking evidence to justification: one's justification for the belief that p can be no higher than it is on one's total evidence, nor can it be higher than what it would have been had one had all of the evidence one should have had. Together, these two principles entail what I call the doctrine of Epistemic Strict Liability: insofar as one fails to have evidence one should have had, one is epistemically answerable to that evidence whatever reasons one happened to have regarding the likely epistemic bearing of that evidence. I suggest that such a position can account for the battery of intuitions elicited in the full range of cases I will be considering. (shrink)

Certain plausible evidential requirements and coherence requirements on rationality seem to yield dilemmas of rationality (in a specific, objectionable sense) when put together with the possibility of misleading higher-order evidence. Epistemologists have often taken such dilemmas to be evidence that we’re working with some false principle. In what follows I show how one can jointly endorse an evidential requirement, a coherence requirement, and the possibility of misleading higher-order evidence without running afoul of dilemmas of rationality. The trick lies in observing (...) the difference between attitudes it is rational to hold (= propositional justification) and rationally holding those attitudes (= doxastic justification). (shrink)

An important question in epistemology concerns how the two species of justification, propositional and doxastic justification, are related to one another. According to the received view, basing one’s belief p on the grounds that provide propositional justification to believe p is sufficient for the belief to be doxastically justified. In a recent paper, however, John Turri has suggested that we should reverse the direction of explanation. In this paper, I propose to see the debate in a new light by suggesting (...) that the best way to understand the relationship between these species of justification is by viewing propositional justification as an dispositional property that a subject can have with doxastic justification as its manifestation. I show how the debate in metaphysics over the question of how disposition statements should be analyzed runs parallel to the epistemological debate, and bring some of the results in the dispositions debate to bear on the epistemological question. I end by offering some tentative remarks regarding the order of priority of these two species of justification. (shrink)
