Modal epistemologists parse modal conditions on knowledge in terms of metaphysical possibilities or ways the world might have been. This is problematic. Understanding modal conditions on knowledge this way has made modal epistemology, as currently worked out, unable to account for epistemic luck in the case of necessary truths, and unable to characterise widely discussed issues such as the problem of religious diversity and the perceived epistemological problem with knowledge of abstract objects. Moreover, there is reason to think that this (...) is a congenital defect of orthodox modal epistemology. This way of characterising modal epistemology is however optional. It is shown that one can non-circularly characterise modal conditions on knowledge in terms of epistemic possibilities, or ways the world might be for the target agent. Characterising the anti-luck condition in terms of epistemic possibilities removes the impediment to understanding epistemic luck in the case of necessary truths and opens the door to using these conditions to shed new light on some longstanding epistemological problems.

This Introduction to the special issue on “Skepticism and Justification” provides a background to the nine articles collected here and a detailed summary of each, which highlights their interconnections and relevance to the debate at the heart of the issue.

ABSTRACT The paper proposes that the distinctive features of aesthetic assertion are due to a special norm governing such assertion rather than any semantic features of aesthetic predication. The norm is elaborated as a reading of Kant’s analysis of aesthetic judgment. Apart from the proposed norm capturing various features of aesthetic assertion, it is supported by various linguistic considerations that point to the semantic profile of predicates of personal taste and aesthetic predicates being in fact alike with respect to the (...) role of a judge or experiencer in the interpretation of the respective kinds of assertions. The difference between the two, therefore, must have a different source than the understood role of an agent, viz. the advertised norm. In particular, it is argued that the role of an explicit agent in both predicates acts to signal a presupposition of another agent having a different experience or judgment from the speaker rather than an articulation of the content of the predicate itself or a determination of its truth value.

Timothy Williamson has fruitfully exploited formal resources to shed considerable light on the nature of knowledge. In the paper under examination, Williamson turns his attention to Gettier cases, showing how they can be motivated formally. At the same time, he disparages the kind of justification he thinks gives rise to these cases. He favors instead his own notion of justification for which Gettier cases cannot arise. We take issue both with his disparagement of the kind of justification that figures in (...) Gettier cases and the specifics of the formal motivation. (shrink)

The problem of easy knowledge arises for theories that have what I call a “basic knowledge structure”. S has basic knowledge of P just in case S knows P prior to knowing that the cognitive source of S's knowing P is reliable.1 Our knowledge has a basic knowledge structure (BKS) just in case we have basic knowledge and we come to know our faculties are reliable on the basis of our basic knowledge. The problem I raised in “Basic Knowledge and (...) the Problem of Easy Knowledge”2 (BKEK) is that once we allow for basic knowledge, we can come to know our faculties are reliable in ways that intuitively are too easy. This raises a serious doubt about whether we had the basic knowledge in the first place. In “Easy Knowledge”, Peter Markie argues that BKS theories do not face any problem concerning easy knowledge.3 I argued that the problem arises in two forms, and Markie takes issue with both. I will argue that Markie's defense of BKS theories fails. (shrink)

The problem of perception is the problem of explaining how perceptual knowledge is possible. The skeptic has a simple solution: it is not possible. I analyze the weaknesses of one type of skeptical reasoning by making explicit a dynamic epistemic principle from dynamic epistemic logic that is implicitly used in debating the problem, with the aim of offering a novel diagnosis to this skeptical argument. I argue that prominent modest foundationalist responses to perceptual skepticism can be understood as rejecting the (...) dynamic assumption made by the skeptic, that there are independent reasons to doubt the truth of such a principle in the context of skeptical reasoning, and that making the dynamic principle explicit allows for a better understanding of at least one objection to modest foundationalism. (shrink)

Cases of inexact observations have been used extensively in the recent literature on higher-order evidence and higher-order knowledge. I argue that the received understanding of inexact observations is mistaken. Although it is convenient to assume that such cases can be modeled statically, they should be analyzed as dynamic cases that involve change of knowledge. Consequently, the underlying logic should be dynamic epistemic logic, not its static counterpart. When reasoning about inexact knowledge, it is easy to confuse the initial situation, the (...) observation process, and the result of the observation; I analyze the three separately. This dynamic approach has far reaching implications: Williamson’s influential argument against the KK principle loses its force, and new insights can be gained regarding synchronic and diachronic introspection principles.

This paper advances the debate over the question whether false beliefs may nevertheless have warrant, the property that yields knowledge when conjoined with true belief. The paper’s first main part—which spans Sections 2–4—assesses the best argument for Warrant Infallibilism, the view that only true beliefs can have warrant. I show that this argument’s key premise conflicts with an extremely plausible claim about warrant. Sections 5–6 constitute the paper’s second main part. Section 5 presents an overlooked puzzle about warrant, and uses (...) that puzzle to generate a new argument for Warrant Fallibilism, the view that false beliefs can have warrant. Section 6 evaluates this pro-Fallibilism argument, finding ultimately that it defeats itself in a surprising way. I conclude that neither Infallibilism nor Fallibilism should now constrain theorizing about warrant. (shrink)

This essay aims to reorient current theorizing about luck as an aid to our discerning this concept's true philosophical significance. After introducing the literature's leading theories of luck, it presents and defends counterexamples to each of them. It then argues that recent luck theorists’ main target of analysis—the concept of an event's being lucky for a subject—is parasitic on the more fundamental notion of an event's being a stroke of luck for a subject, which thesis serves as at least a (...) partial diagnosis of the leading theories’ failure. Next, it develops an analysis of strokes of luck that utilizes insights from the recent luck literature. Finally, having set out a comprehensive new analysis of luck—the Enriched Strokes Account of lucky events—the essay revisits the initial counterexamples to the literature's leading theories and argues that the Enriched Strokes Account properly handles all of them.

Luck looms large in numerous different philosophical subfields. Unfortunately, work focused exclusively on the nature of luck is in short supply on the contemporary analytic scene. In his highly impressive recent book Epistemic Luck, Duncan Pritchard helps rectify this neglect by presenting a partial account of luck that he uses to illuminate various ways luck can figure in cognition. In this paper, I critically evaluate both Pritchard’s account of luck and another account to which Pritchard’s discussion draws our attention—viz., that (...) due to Nicholas Rescher. I also assess some novel analyses of luck that incorporate plausible elements of Pritchard’s and Rescher’s accounts. (shrink)

This paper has two main parts. In the first part, I argue that prominent moves in two related current debates in epistemology—viz., the debates over classical invariantism and the knowledge first movement—depend on one or the other of two claims about epistemic propriety: (1) Impropriety due to lack of a particular epistemic feature suffices for epistemic impropriety; and (2) Having justification to believe P suffices for having warrant to assert P. In the second part, I present and defend novel arguments (...) against both claims. (shrink)

Gettiered beliefs are those whose agents are subject to the kind of epistemologically significant luck illustrated by Gettier Cases. Provided that knowledge requires ungettiered belief, we can learn something about knowledge by figuring out how luck blocks it in Gettier Cases. After criticizing the most promising of the going approaches to gettiered belief—the Risk of False Belief Approach—, I explain and defend a new approach: the Risk of Misleading Dispositions Approach.Roughly, this view says that a belief is gettiered just in (...) case its unfortunate subject has at best just luckily avoided being disposed by his belief’s actual grounds to believe a wide class of falsehoods about his environment. I then show how this approach undercuts an influential recent argument that knowledge has no more value than certain subsets of its components. (shrink)

Blake Roeber argues that examples of a certain neglected kind cast doubt on the following piece of epistemological orthodoxy: your acquisition of a particular belief couldn’t itself be a directly voluntary action. In this paper, I undermine and then rebut Roeber’s anti-involuntarism conclusion. After arguing for the denial of one of the premises on which Roeber’s conclusion is based, I articulate a plausible pro-involuntarism explanation of Roeber’s focal example.

This paper fortifies and defends the so called Sufficiency Argument (SA) against Classical Invariantism. In Sect. 2,I explain the version of the SA formulated but then rejected by Brown (2008a). In Sect. 3, I show how cases described by Hawthorne (2004), Brown (2008b), and Lackey (forthcoming) threaten to undermine one or the other of the SA's least secure premises. In Sect. 4,I buttress one of those premises and defend the reinforced SA from the objection developed in Sect. 3.

The epistemic probability of A given B is the degree to which B evidentially supports A, or makes A plausible. This paper is a first step in answering the question of what determines the values of epistemic probabilities. I break this question into two parts: the structural question and the substantive question. Just as an object’s weight is determined by its mass and gravitational acceleration, some probabilities are determined by other, more basic ones. The structural question asks what probabilities are (...) not determined in this way—these are the basic probabilities which determine values for all other probabilities. The substantive question asks how the values of these basic probabilities are determined. I defend an answer to the structural question on which basic probabilities are the probabilities of atomic propositions conditional on potential direct explanations. I defend this against the view, implicit in orthodox mathematical treatments of probability, that basic probabilities are the unconditional probabilities of complete worlds. I then apply my answer to the structural question to clear up common confusions in expositions of Bayesianism and shed light on the “problem of the priors.”. (shrink)

In "Mathematical Truth", Paul Benacerraf articulated an epistemological problem for mathematical realism. His formulation of the problem relied on a causal theory of knowledge which is now widely rejected. But it is generally agreed that Benacerraf was onto a genuine problem for mathematical realism nevertheless. Hartry Field describes it as the problem of explaining the reliability of our mathematical beliefs, realistically construed. In this paper, I argue that the Benacerraf Problem cannot be made out. There simply is no intelligible problem (...) that satisfies all of the constraints which have been placed on the Benacerraf Problem. The point generalizes to all arguments with the structure of the Benacerraf Problem aimed at realism about a domain meeting certain conditions. Such arguments include so-called "Evolutionary Debunking Arguments" aimed at moral realism. I conclude with some suggestions about the relationship between the Benacerraf Problem and the Gettier Problem. (shrink)

Could it be right to convict and punish defendants using only statistical evidence? In this paper, I argue that it is not and explain why it would be wrong. This is difficult to do because there is a powerful argument for thinking that we should convict and punish defendants using statistical evidence. It looks as if the relevant cases are cases of decision under risk and it seems we know what we should do in such cases (i.e., maximize expected value). (...) Given some standard assumptions about the values at stake, the case for convicting and punishing using statistical evidence seems solid. In trying to show where this argument goes wrong, I shall argue (against Lockeans, reliabilists, and others) that beliefs supported only by statistical evidence are epistemically defective and (against Enoch, Fisher, and Spectre) that these epistemic considerations should matter to the law. To solve the puzzle about the role of statistical evidence in the law, we need to revise some commonly held assumptions about epistemic value and defend the relevance of epistemology to this practical question. (shrink)

A large chorus of voices has grown around the claim that theistic belief is epistemically suspect since, as some cognitive scientists have hypothesized, such beliefs are a byproduct of cognitive mechanisms which evolved for rather different adaptive purposes. This paper begins with an overview of the pertinent cognitive science followed by a short discussion of some relevant epistemic concepts. Working from within a largely Williamsonian framework, we then present two different ways in which this research can be formulated into an (...) argument against theistic belief. We argue that neither version works. (shrink)

It is argued, on the basis of new counterexamples, that neither knowledge nor epistemic justification (or epistemic rationality ) can reasonably be thought to be closed under logical implication. The argument includes an attempt to reconcile the fundamental intuitions of the opposing parties in the debate.

In this paper, I lend credence to the move toward non-reductive religious epistemology by highlighting the systematic failings of Alvin Plantinga’s seminal, religious epistemology when it comes to surmounting the Gettier Problem. Taking Plantinga’s account as archetypal, I argue that we have systematic reasons to believe that no reductive theory of knowledge can viably surmount the Gettier Problem, that the future of religious epistemology lies in non-reductive models of knowledge.

What are intuitions? According to doxastic views, they are doxastic attitudes or dispositions, such as judgments or inclinations to make judgments. According to perceptualist views, they are—like perceptual experiences—pre-doxastic experiences that—unlike perceptual experiences—represent abstract matters as being a certain way. In this paper I argue against doxasticism and in favor of perceptualism. I describe two features that militate against doxasticist views of perception itself: perception is belief-independent and perception is presentational. Then I argue that intuitions also have both features. The (...) upshot is that intuitions are importantly similar to perceptual experiences, and so should not be identified with doxastic attitudes or dispositions. I consider a popular argument from the introspective absence of sui generis intuition experiences in favor of doxasticism. I develop a conception of intuition experiences that helps to defuse this argument. (shrink)

Fallibilists about looks deny that the relation of looking the same as is non-transitive. Regarding familiar examples of coloured patches suggesting that such a relation is non-transitive, they argue that, in fact, indiscriminable adjacent patches may well look different, despite their perceptual indiscriminability: it’s just that we cannot notice the relevant differences in the chromatic appearances of such patches. In this paper, I present an argument that fallibilism about looks requires commitment to an empirically false consequence. To succeed in deflecting (...) putative cases of non-transitivity, fallibilists would have to claim that there can’t be any perceptual limitations of any kind on human chromatic discrimination. But there are good reasons to think such limitations exist. (shrink)

If the history of the Gettier Problem has taught us anything, it is to be skeptical regarding purported solutions. Nevertheless, in “Manifest Failure: The Gettier Problem Solved” (2011), that is precisely what John Turri offers us. For nearly fifty years, epistemologists have been chasing a solution for the Gettier Problem but with little to no success. If Turri is right, if he has actually solved the Gettier Problem, then he has done something that is absolutely groundbreaking and really quite remarkable. (...) Regrettably, however, while Turri’s account is both intuitive and elegant—improving upon many seminal projects within contemporary epistemology—I argue in this paper that any success against Gettier counterexamples it affords is merely fleeting. Straightforwardly, this is done in two sections. In §1, I briefly sketch Turri’s proposed solution to the Gettier Problem. Then, in §2, I level a counterexample against it. Unfortunately for Turri and his solution, in this paper we will see history repeat itself. (shrink)

In this paper I assume that we have some intuitive knowledge—i.e. beliefs that amount to knowledge because they are based on intuitions. The question I take up is this: given that some intuition makes a belief based on it amount to knowledge, in virtue of what does it do so? We can ask a similar question about perception. That is: given that some perception makes a belief based on it amount to knowledge, in virtue of what does it do so? (...) A natural idea about perception is that a perception makes a belief amount to knowledge in part by making you sensorily aware of the concrete objects it is about. The analogous idea about intuition is that an intuition makes a belief amount to knowledge in part by making you intellectually aware of the abstract objects it is about. I expand both ideas into fuller accounts of perceptual and intuitive knowledge, explain the main challenge to this sort of account of intuitive knowledge (i.e. the challenge of making sense of intellectual awareness), and develop a response to it. (shrink)

In this paper I add credence to Linda Zagzebski's (1994) diagnosis of Gettier problems (and the current trend to abandon the standard analysis) by analyzing the nature of luck. It is widely accepted that the lesson to be learned from Gettier problems is that knowledge is incompatible with luck or at least a certain species thereof. As such, understanding the nature of luck is central to understanding the Gettier problem. Thanks by and large to Duncan Pritchard's seminal work, Epistemic Luck, (...) a great deal of literature has been developed recently concerning the nature of luck and anti-luck epistemology. The literature, however, has yet to explore the very intuitive idea that luck comes in degrees. I propose that once luck is recognized to admit degrees even the slightest non-zero degree (of the relevant sort) precludes knowledge. Connecting this to Zagzebski's thesis, I propose that a given theory of warrant must guarantee truth in order to avoid Gettier counterexamples (or subsequently deny that warrant bears any relationship to the truth whatsoever), simply because a sufficient standard analysis of knowledge cannot allow for knowledge that is even marginally lucky. (shrink)

The Gettier Problem is the problem of revising the view that knowledge is justified true belief in a way that is immune to Gettier counter-examples. The “Gettier Problem problem”, according to Lycan, is the problem of saying what is misguided about trying to solve the Gettier Problem. In this paper I take up the Gettier Problem problem. I distinguish giving conditions that are necessary and sufficient for knowledge from giving conditions that explain why one knows when one does know. I (...) argue that the problem with the Gettier Problem is that it requires us to articulate conditions that suffice for knowledge even if those conditions are non-explanatory. After defending this view, I take up two related methodological issues, one about the evidence that can be given in favor of an account of knowledge, and one about the role that investigating justification might play in investigating knowledge.

Formal theories, as in logic and mathematics, are sets of sentences closed under logical consequence. Philosophical theories, like scientific theories, are often far less formal. There are many axiomatic theories of the truth predicate for certain formal languages; on analogy with these, some philosophers (most notably Paul Horwich) have proposed axiomatic theories of the property of truth. Though in many ways similar to logical theories, axiomatic theories of truth must be different in several nontrivial ways. I explore what an axiomatic (...) theory of truth would look like. Because Horwich’s is the most prominent, I examine his theory and argue that it fails as a theory of truth. Such a theory is adequate if, given a suitable base theory, every fact about truth is a consequence of the axioms of the theory. I show, using an argument analogous to Gödel’s incompleteness proofs, that no axiomatic theory of truth could ever be adequate. I also argue that a certain class of generalizations cannot be consequences of the theory. (shrink)

In an attempt to improve upon Alexander Pruss’s work (The principle of sufficient reason: A reassessment, pp. 240–248, 2006), I (Weaver, Synthese 184(3):299–317, 2012) have argued that if all purely contingent events could be caused and something like a Lewisian analysis of causation is true (per, Lewis’s, Causation as influence, reprinted in: Collins, Hall and paul. Causation and counterfactuals, 2004), then all purely contingent events have causes. I dubbed the derivation of the universality of causation the “Lewisian argument”. The Lewisian (...) argument assumed not a few controversial metaphysical theses, particularly essentialism, an incommunicable-property view of essences (per Plantinga’s, Actualism and possible worlds, reprinted in: Davidson (ed.) Essays in the metaphysics of modality, 2003), and the idea that counterfactual dependence is necessary for causation. There are, of course, substantial objections to such theses. While I think a fight against objections to the Lewisian argument can be won, I develop, in what follows, a much more intuitive argument for the universality of causation which takes as its inspiration a result from Frederic B. Fitch’s work (J Symb Logic 28(2):135–142, 1963) [with credit to who we now know was Alonzo church’s, Referee Reports on Fitch’s Definition of value, in: (Salerno (ed.), New essays on the knowability paradox, 2009)] that if all truths are such that they are knowable, then (counter-intuitively) all truths are known. The resulting Church–Fitch proof for the universality of causation is preferable to the Lewisian argument since it rests upon far weaker formal and metaphysical assumptions than those of the Lewisian argument. (shrink)

Akratic belief, or belief one believes one should not have, has often been thought to be impossible. I argue that the possibility of akratic belief should be accepted as a pre-theoretical datum. I distinguish intuitive, defensive, systematic, and diagnostic ways of arguing for this view, and offer an argument that combines them. After offering intuitive examples of akratic belief, I defend those examples against a common argument against the possibility of akratic belief, which I call the Nullification Argument. I then (...) offer an Argument from Belief Attribution, using a discussion of the marks by which we typically attribute belief to defend attributions of akratic belief. I conclude by offering a way to explain what is puzzling about akratic belief, while allowing that it is possible. (shrink)

We have no reason to believe that reasons do not exist. Contra Bart Streumer’s recent proposal, this has nothing to do with our incapacity to believe this error theory. Rather, it is because if we know that if a proposition is true, we have no reason to believe it, then we have no reason to believe this proposition. From a different angle: if we know that we have at best misleading reasons to believe a proposition, then we have no reason (...) to believe it. This has two consequences. Firstly, coming close to believing the error theory is idle or pointless. Secondly, philosophers who argue that believing sweeping theories like determinism or physicalism is self-defeating because they are either false or believed for no reason pursue a worthwhile argumentative strategy.

In this paper, I consider a popular version of the clever student’s reasoning in the surprise examination case, and demonstrate that a valid argument can be constructed. The valid argument is a reductio ad absurdum with the proposition that the student knows on the morning of the first day that the teacher’s announcement is fulfilled as its reductio. But it would not give rise to any paradox. In the process, I criticize Saul Kripke’s solution and Timothy Williamson’s attack on a (...) key step of the student’s reasoning. I then consider the condemned prisoner case in W. V. Quine’s paper ‘On a So-Called Paradox’. I argue that the prisoner’s reasoning as conceived by Quine is more relevant and reasonable than the student’s argument in the popular version of the surprise examination case. I also argue that Quine’s criticism of the prisoner’s reasoning is correct, and therefore that the condemned prisoner case, and the surprise examination case as well, would not generate any paradox.

I develop the relatively familiar idea of a variety of forms of knowledge —not just propositional knowledge but also knowledge -how and experiential knowledge —and show how this variety can be used to make interesting sense of Plato’s and Aristotle’s philosophy, and in particular their ethics. I then add to this threefold analysis of knowledge a less familiar fourth variety, objectual knowledge, and suggest that this is also interesting and important in the understanding of Plato and Aristotle.

This paper argues for and explores the implications of the following epistemological principle for knowability a priori (with 'Ka' abbreviating 'it is knowable a priori that'). -/- (AK) For all ϕ, ψ such that ϕ semantically presupposes ψ: if Ka(ϕ), Ka(ψ). -/- Well-known arguments for the contingent a priori and a priori knowledge of logical truth founder when the semantic presuppositions of the putative items of knowledge are made explicit. Likewise, certain kinds of analytic truth turn out to carry semantic (...) presuppositions that make them ineligible as items of a priori knowledge. -/- On a happier note, I argue that (AK) offers an appealing, theory-neutral explanation of the a posteriori character of certain necessary identities, as well as an interesting rationalization for a commonplace linguistic maneuver in philosophical work on the a priori.

One version of Moore’s Paradox is the challenge to account for the absurdity of beliefs purportedly expressed by someone who asserts sentences of the form ‘p & I do not believe that p’. The absurdity of these beliefs is philosophically puzzling, given that Moorean sentences are contingent and often true; and express contents that are unproblematic when presented in the third-person. In this paper I critically examine the most popular proposed solution to these two puzzles, according to which Moorean beliefs (...) are absurd because Moorean sentences are instances of pragmatic paradox; that is to say, the propositions they express are necessarily false-when-believed. My conclusion is that while a Moorean belief is a pragmatic paradox, it is not just another pragmatic paradox, because this diagnosis does not explain all the puzzling features of Moorean beliefs. In particularly, while this analysis is plausible in relation to the puzzle posed by characteristic of Moorean sentences, I argue that it fails to account for. I do so in the course of an attempt to formulate the definition of a pragmatic paradox in more precise formal terms, in order to see whether the definition is satisfied by Moorean sentences, but not by their third-person transpositions. For only an account which can do so could address adequately. After rejecting a number of attempted formalizations, I arrive at a definition which delivers the right results. The problem with this definition, however, is that it has to be couched in first-person terms, making an essential use of ‘I’. Thus the problem of accounting for first-/third-person asymmetry recurs at a higher order, which shows that the Pragmatic Paradox Resolution fails to identify the source of such asymmetry highlighted by Moore’s Paradox.

One diagnosis of Fitch’s paradox of knowability is that it hinges on the factivity of knowledge: that which is known is true. Yet the apparent role of factivity and non-factive analogues in related paradoxes of justified belief can be shown to depend on familiar consistency and positive introspection principles. Rejecting arguments that the paradox hangs on an implausible consistency principle, this paper argues instead that the Fitch phenomenon is generated both in epistemic logic and logics of justification by the interaction (...) of analogues of the knowability principle and positive introspection theses that are characteristic of, even if not entailed by, epistemic internalism.

In this article I argue that two received accounts of belief and assertion cannot both be correct, because they entail mutually contradictory claims about Moore's Paradox. The two accounts in question are, first, the Action Theory of Belief, the functionalist view that belief must be manifested in dispositions to act, and second, the Belief Account of Assertion, the Gricean view that an asserter must present himself as believing what he asserts. It is generally accepted also that Moorean assertions are absurd, (...) and that BAA explains why they are. I shall argue that ATB implies that some Moorean assertions are, in some fairly ordinary contexts, well justified. Thus BAA and ATB are mutually inconsistent. In the concluding section I explore three possible ways of responding to the dilemma, and what implications they have for the nature of the constitutive relationships linking belief, assent and behavioural dispositions.

The view that the subject matter of epistemology is the concept of knowledge is faced with the problem that all attempts so far to define that concept are subject to counterexamples. As an alternative, this article argues that the subject matter of epistemology is knowledge itself rather than the concept of knowledge. Moreover, knowledge is not merely a state of mind but rather a certain kind of response to the environment that is essential for survival. In this perspective, the article (...) outlines an answer to four basic questions about knowledge: What is the role of knowledge in human life? What is the relation between knowledge and reality? How is knowledge acquired? Is there any a priori knowledge? (shrink)

Vice epistemology is the philosophical study of the nature, identity, and epistemological significance of intellectual vices. Such vices include gullibility, dogmatism, prejudice, closed-mindedness, and negligence. These are intellectual character vices, that is, intellectual vices that are also character traits. I ask how the notion of an intellectual character vice should be understood, whether such vices exist, and how they might be epistemologically significant. The proposal is that intellectual character vices are intellectual character traits that impede effective and responsible inquiry. I (...) argue that situationist critiques of virtue epistemology pose no significant threat to this proposal. Studies by social psychologists of belief in conspiracy theories suggest that it is sometimes appropriate to explain questionable beliefs by reference to intellectual character vices. Neither ‘regulative’ nor ‘analytic’ epistemology has any good reason to question the epistemological significance of such vices. (shrink)

How is knowledge of the external world possible? How is knowledge of other minds possible? How is a priori knowledge possible? These are all examples of how-possible questions in epistemology. In this highly original book Quassim Cassam explains how such questions arise and how they should be answered.

I discuss the claim what makes self-knowledge epistemologically distinctive is the fact that it is baseless or groundless. I draw a distinction between evidential and explanatory baselessness and argue that self-knowledge is only baseless in the first of these senses. Since evidential baselessness is a relatively widespread phenomenon the evidential baselessness of self-knowledge does not make it epistemologically distinctive and does not call for any special explanation. I do not deny that self-knowledge is epistemologically distinctive. My claim is only that (...) talk of its evidential baselessness is insufficient to account for its epistemological distinctiveness.

According to robust virtue epistemology , knowledge is type-identical with a particular species of cognitive achievement. The identification itself is subject to some criticism on the grounds that it fails to account for the anti-luck features of knowledge. Although critics have largely focused on environmental luck, the fundamental philosophical problem facing RVE is that it is not clear why it should be a distinctive feature of cognitive abilities that they ordinarily produce beliefs in a way that is safe. We propose (...) a novel way to resolve this problem. Key to our proposal will be an appreciation of different representational states beholden to truth. We suggest these different representational states are distinguished by how, in the proper governance of these states, the twin goods of attaining truth and avoiding error are weighted. Moreover, we explain how varieties of representational states line up with varieties of cognitive achievement such that knowledge, cum cognitive achievement, must be safe because of the kind of attempt at success that belief is—namely, an attempt that places the premium it does on avoiding error.
