Is knowledge justified true belief? Most philosophers believe that the answer is clearly ‘no’, as demonstrated by Gettier cases. But Gettier cases don’t obviously refute the traditional view that knowledge is justified true belief (JTB). There are ways of resisting Gettier cases, at least one of which is partly successful. Nevertheless, when properly understood, Gettier cases point to a flaw in JTB, though it takes some work to appreciate just what it is. The nature (...) of the flaw helps us better understand the nature of knowledge and epistemic justification. I propose a crucial improvement to the traditional view, relying on an intuitive and independently plausible metaphysical distinction pertaining to the manifestation of intellectual powers, which supplements the traditional components of justification, truth and belief.

There is a traditional conception of knowledge but it is not the Justified True Belief analysis Gettier attacked. On the traditional view, knowledge consists in having a belief that bears a discernible mark of truth. A mark of truth is a truth-entailing property: a property that only true beliefs can have. It is discernible if one can always tell that a belief has it, that is, a sufficiently attentive subject believes that a belief (...) has it if and only if it has it. Requiring a mark of truth makes the view infallibilist. Requiring it to be discernible makes the view internalist. I call the view Classical Infallibilism. (shrink)

Intuitively, there is a difference between knowledge and mere belief. Contemporary philosophical work on the nature of this difference has focused on scenarios known as “Gettier cases.” Designed as counterexamples to the classical theory that knowledge is justified true belief, these cases feature agents who arrive at true beliefs in ways which seem reasonable or justified, while nevertheless seeming to lack knowledge. Prior empirical investigation of these cases has raised questions about whether lay people (...) generally share philosophers’ intuitions about these cases, or whether lay intuitions vary depending on individual factors (e.g. ethnicity) or factors related to specific types of Gettier cases (e.g. cases that include apparent evidence). We report an experiment on lay attributions of knowledge and justification for a wide range of Gettier Cases and for a related class of controversial cases known as Skeptical Pressure cases, which are also thought by philosophers to elicit intuitive denials of knowledge. Although participants rated true beliefs in Gettier and Skeptical Pressure cases as being justified, they were significantly less likely to attribute knowledge for these cases than for matched true belief cases. This pattern of response was consistent across different variations of Gettier cases and did not vary by ethnicity or gender, although attributions of justification were found to be positively related to measures of empathy. These findings therefore suggest that across demographic groups, laypeople share similar epistemic concepts with philosophers, recognizing a difference between knowledge and justified true belief.

This chapter argues that olfactory experiences represent either everyday objects or ad hoc olfactory objects as having primitive olfactory properties, which happen to be uninstantiated. On this picture, olfactory experiences reliably misrepresent: they falsely represent everyday objects or ad hoc objects as having properties they do not have, and they misrepresent in the same way on multiple occasions. One might worry that this view is incompatible with the plausible claim that olfactory experiences at least sometimes justify true beliefs about (...) the world. This chapter argues that there is no such incompatibility. Since olfactory experiences reliably misrepresent, they can lead to true and justified beliefs about putatively smelly objects. (shrink)

[ES] En este breve trabajo, se presenta una edición bilingüe de Is Justified True Belief Knowledge?, de Edmund L. Gettier, donde se presentan contraejemplos a la definición de «conocimiento» como «creencia verdadera justificada». [ES] In this brief text, a bilingual edition of Is Justified True Belief Knowledge?, by Edmund L. Gettier, some counterexamples are presented to the definition of «knowledge» as «justified true belief».

I argue in this paper that the cases Gettier considers are not examples of justified true beliefs and that the question whether justified true belief sufficiently defines knowledge is not in fact, addressed. Indeed, the question is wholly untouched by Gettier or glossed over at best.

I briefly discuss the Gettier Problem, problems with the justified theory of true belief, and offer support for Feldman's concept of no false grounds.

Edmund Gettier (1963) argued that there can be justified true belief (JTB) that is not knowledge. I question the correctness of his argument by showing that Smith of Gettier’s famous examples does not earn justification for his incidentally true beliefs, while a doxastically more conscientious person S would come to hold justified but false beliefs. So, Gettier’s (and analogous) cases do not result in justified _and_ true belief. This is due to a (...) tension between deductive closure of justification and evidential support. For being justified, any believing, disbelieving, or withholding of deductively inferred propositions must be distributed proportionally to given evidential support. This proportionality principle has primacy over deductive closure in case of conflict. My argument does not save the JTB-account. But, instead of merely referring to an intuition, it explains why subjects in Gettier situations do not earn knowledge. (shrink)

Abstract: This paper endeavors to establish a comprehensive account of human knowledge that embraces the probabilistic nature of truth, the integral role of language in our cognitive processes, and the uncertainty and fallibility inherent in our cognitive systems. Drawing upon the work of various philosophers, psychologists, and neuroscientists, the paper advocates for a reinterpretation of the traditional "Justified True Belief" as "Justified Probable Belief." Additionally, the biological underpinnings of this perspective are explored, with an emphasis (...) on synaptic plasticity, dopamine-based learning, and epigenetic mechanisms. (shrink)

The main lesson from Gettier cases is that while one cannot know a proposition by luck, one can hold a lucky true belief justifiedly. Possibly because the latter is taken for granted, the relationship between epistemic justification and epistemic luck has been less discussed. The paper investigates whether luck can undermine doxastic justification, and if so, how and to what extent. It is argued that, as in the case of knowledge, beliefs can fall short of justification due to (...) luck. Moreover, it is argued that justification-undermining luck is a problem for both internalist and externalist conceptions of justification. Accordingly, it is shown that epistemic luck is a more widespread phenomenon than many in epistemology commonly assume. (shrink)

The New Demon World Objection claims that reliabilist accounts of justification are mistaken because there are justified empirical beliefs at demon worlds—worlds at which the subjects are systematically deceived by a Cartesian demon. In this paper, I defend strongly verific (but not necessarily reliabilist) accounts of justification by claiming that there are two ways to construct a theory of justification: by analyzing our ordinary concept of justification or by taking justification to be a theoretic term defined by its role (...) in the theory of knowledge. The former route is not promising because of the splintered nature of our ordinary concept of justification—or perhaps because there is no single such concept. On the other hand, if justification is defined by the role it plays in the theory of knowledge, then there is good reason to think that justification must be strongly truth-conductive since the term was introduced by Edmund Gettier to play the primary role in converting true belief into knowledge. And if that is right, then there will be no justified empirical belief at demon worlds. The real lesson of the demon world is then turned on its head: justification does not supervene on what one shares with one’s deceived doppelganger. (shrink)

The present paper depicts Moser’s view on the justification of the belief in God. By debunking the efficiency of mere theoretical reason in proving the existence of God, introducing God as the source of justification, and using a moral perspective, he proposes a kind of voluntary knowledge. He assumes the right path to acquire true knowledge of god to be a direct and purposeful evidence, which is found in accordance to divine attributes. For their own redemption, before the (...) interference of thought and feelings, God wills the voluntary moral revolution of human beings from selfishness to selfless absolute love. In this respect, Moser puts forth a virtue-based evidentialism, on the basis of which people can accept God’s invitation to friendship with absolute love and therefore experience God’s blessing in their motivational core. This experience indicates God’s self-manifestation and offers direct evidence for his existence, which causes the subject, by gaining moral attributes and receiving God’s absolute love and sharing it with others, to become a personified evidence of God himself. Moreover, according to the inference to the best explanation, Moser justifies the belief in God by this empirical and non-propositional evidence. As a result, Moser’s existential and moral account, despite being criticized for its being subjective and relative, and the unreliability of religious experiences, has revived a number of forgotten theological concepts.

That in Gettier's alleged counterexamples to the traditional analysis of knowledge as justified true belief the belief condition is satisfied has rarely been questioned. Yet there is reason to doubt that a rational person would come to believe what Gettier's protagonists are said to believe in the way they are said to have come to believe it. If they would not, the examples are not counter-examples to the traditional analysis. I go on to discuss a number (...) of examples inspired by Gettier's and argue that they, too, fail to be counter-examples either for reasons similar to those I have urged or because it is not clear that their subject does not know.

In this paper, we claim that, if you justifiably believe that you ought to perform some act, it follows that you ought to perform that act. In the first half, we argue for this claim by reflection on what makes for correct reasoning from beliefs about what you ought to do. In the second half, we consider a number of objections to this argument and its conclusion. In doing so, we arrive at another argument for the view that justified (...) beliefs about what you ought to do must be true, based in part on the idea that the epistemic and practical domains are uniform, in a sense we spell out. We conclude by sketching possible implications of our discussion for the debates over what is wrong with akrasia and pragmatic encroachment on justified belief and knowledge. (shrink)

One of the most discussed articles in the theory of knowledge is Edmund Gettier’s article “Is Justified True Belief Knowledge?”, published in 1963. In this article Gettier undermined the view that knowledge is justified true belief. I think that Gettier’s analysis has consequences not only for the question what knowledge is but also for our idea of truth. In this paper I argue that an analysis in the sense of Gettier shows that a statement (...) can be both true and not true at the same time. (shrink)

The secondary literature on religious epistemology has focused extensively on whether religious experience can provide evidence for God’s existence. In this article, I suppose that religious experience can do this, but I consider whether it can provide adequate evidence for justified belief in God. I argue that it can. This requires a couple of moves. First, I consider the threshold problem for evidentialism and explain pragmatic encroachment (PE) as a solution to it. Second, I argue that religious experience (...) can justify belief in God if one adopts PE, but this poses a dilemma for the defender of the veridicality of religious experience. If PE is true, then whether S has a justified belief in God on the basis of religious experience depends on how high the stakes are for having an experience with God. This requires one to determine whether the stakes are high or low for experiencing God, which puts the experient of God in an awkward position. If the stakes are not high, then justified belief in God on the basis of religious experience will be easier to come by, but this requires conceding that experiencing God is not that important. If the stakes are high, then the experient can maintain the importance of experience with God but must concede that justified belief in God on the basis of experience with God is less likely to happen, perhaps impossible.

Reliabilists hold that a belief is doxastically justified if and only if it is caused by a reliable process. But since such a process is one that tends to produce a high ratio of true to false beliefs, reliabilism is on the face of it applicable to binary beliefs, but not to degrees of confidence or credences. For while beliefs admit of truth or falsity, the same cannot be said of credences in general. A natural question now (...) arises: Can reliability theories of justified belief be extended or modified to account for justified credence? In this paper, I address this question. I begin by showing that, as it stands, reliabilism cannot account for justified credence. I then consider three ways in which the reliabilist may try to do so by extending or modifying her theory, but I argue that such attempts face certain problems. After that, I turn to a version of reliabilism that incorporates evidentialist elements and argue that it allows us to avoid the problems that the other theories face. If I am right, this gives reliabilists a reason, aside from those given recently by Comesaña and Goldman, to move towards such a kind of hybrid theory. (shrink)

In philosophy, psychiatry, and cognitive science, definitions of clinical delusions are not based on the mechanisms responsible for the formation of delusions. Some of the defining features of delusions are epistemic and focus on whether delusions are true, justified, or rational, as in the definition of delusions as fixed beliefs that are badly supported by evidence). Other defining features of delusions are psychological and they focus on whether delusions are harmful, as in the definition of delusions as beliefs (...) that disrupt good functioning. Even if the epistemic features go some way towards capturing what otherwise different instances of clinical delusions have in common, they do not succeed in distinguishing delusions as a clinical phenomenon from everyday irrational beliefs. Focusing on the psychological features is a more promising way to mark the difference between clinical and non-clinical irrational beliefs, but there is wide variability in the extent to which delusions are psychologically harmful, and some everyday irrational beliefs can affect functioning in similarly negative ways. In this chapter we consider three types of belief that share similar epistemic features and exhibit variation with respect to how psychologically harmful they are: (1) delusions of thought insertion, (2) alien abduction beliefs, and (3) self-enhancing beliefs. In the light of the similarities and differences between these cases, we highlight the difficulty in providing an answer to what makes an irrational belief delusional. (shrink)

In this paper, I propose a new argument against Gettier’s counterexamples to the thesis that knowledge is justified true belief. I claim that if there is no doxastic voluntarism, and if it is admitted that one has formed the belief that p at t1 if, at t0, one would be surprised to learn or discover that not–p, it can be plausibly argued that Gettiered beliefs simply cannot be formed.

Both of Gettier's examples are not representative of situations in which we would claim knowledge – we do not use language in this way. Therefore, Gettier has not shown that justified true belief is insufficient for knowledge. I am not denying that there is a problem about the definition of knowledge. Several decades earlier, Russell dealt with this problem, using a stopped clock to illustrate it.

Many philosophers claim that interesting forms of epistemic evaluation are insensitive to truth in a very specific way. Suppose that two possible agents believe the same proposition based on the same evidence. Either both are justified or neither is; either both have good evidence for holding the belief or neither does. This does not change if, on this particular occasion, it turns out that only one of the two agents has a true belief. Epitomizing this line (...) of thought are thought experiments about radically deceived “brains in vats.” It is widely and uncritically assumed that such a brain is equally justified as its normally embodied human “twin.” This “parity” intuition is the heart of truth-insensitive theories of core epistemological properties such as justification and rationality. Rejecting the parity intuition is considered radical and revisionist. In this paper, I show that exactly the opposite is true. The parity intuition is idiosyncratic and widely rejected. A brain in a vat is not justified and has worse evidence than its normally embodied counterpart. On nearly every ordinary way of evaluating beliefs, a false belief is significantly inferior to a true belief. Of all the evaluations studied here, only blamelessness is truth-insensitive. (shrink)

Given the significant exculpatory power that ignorance has when it comes to moral, legal, and epistemic transgressions, it is important to have an accurate understanding of the concept of ignorance. According to the Standard View of factual ignorance, a person is ignorant that p whenever they do not know that p, while on the New View, a person is ignorant that p whenever they do not truly believe that p. On their own though, neither of these accounts explains how ignorance (...) can often be a degreed notion—how we can sometimes be slightly ignorant, quite ignorant, or completely ignorant that p. In this paper, I will argue that there is a route for advocates of the Standard View and the New View to accommodate the gradability of ignorance. On the view I defend, ‘ignorant’ picks out everyone that is ignorant to some degree, making it possible that ignorance can be both degreed and characterized as a lack of knowledge or true belief. Even though we can be ignorant to a greater or lesser extent, the only way to avoid being ignorant that p is to know or truly believe. (shrink)

My central thesis is that philosophers considering questions of epistemic value ought to devote greater attention to the enduring nature of beliefs. I begin by arguing that a commonly drawn analogy between beliefs and actions is flawed in important respects, and that a better, more fruitful analogue for belief would be desire, or a similarly enduring state of an agent. With this in hand, I argue that treating beliefs as enduring, constitutive states of agents allows us to capture the (...) importance of accessible, justified, and true beliefs to sustaining personal identity, autonomy, self-control, and authenticity. We thus arrive at a significant value to such beliefs through their crucial role in our personal, practical identities. (shrink)

Philosophers have recently come to focus on explaining the phenomenon of ​bad beliefs,​ beliefs that are apparently true and well-evidenced but nevertheless objectionable. Despite this recent focus, a consensus is already forming around a particular explanation of these beliefs’ badness called ​moral encroachment​, according to which, roughly, the moral stakes engendered by bad beliefs make them particularly difficult to justify. This paper advances an alternative account not just of bad beliefs but of bad attitudes more generally according to which (...) bad beliefs’ badness originates not in a failure of sufficient evidence but in a failure to respond adequately to reasons. I motivate this alternative account through an analogy to recent discussions of moral worth centered on the well-known grocer case from Kant’s ​Groundwork​, and by showing that this analogy permits the proposed account to generalize to bad attitudes beyond belief. The paper concludes by contrasting the implications of moral encroachment and of the proposed account for bad attitudes’ blameworthiness. (shrink)

The evil-god challenge is a challenge for theists to show that belief in God is more reasonable than belief in evil-god. In this article, I show that whether or not evil-god exists, belief in evil-god is unjustified. But this isn’t the case for belief in God: belief in God is probably justified if theism is true. And hence belief in God is (significantly) more reasonable than belief in evil-god, and the evil-god (...) challenge has been answered. (shrink)

False belief tasks have enjoyed a monopoly in the research on children’s development of a theory of mind. They have been granted this status because they promise to deliver an unambiguous assessment of children’s understanding of the representational nature of mental states. Their poor cousins, true belief tasks, have been relegated to occasional service as control tasks. That this is their only role has been due to the universal assumption that correct answers on true belief (...) tasks are inherently ambiguous regarding the level of the child’s understanding of mental states. It has also been due to the universal assumption that nothing in the child’s developing theory of mind would lead to systematically incorrect answers on true belief tasks. We review new findings that 4- and 5-year-olds do err, systematically and profoundly, on the true belief versions of all the extant belief tasks. This reveals an intermediate level of understanding in the development of children’s theory of mind. Researchers have been unaware of this intermediate level because it produces correct answers in false belief tasks. A simple two-task battery—one true belief task and one false belief task—is sufficient to remove the ambiguity from each task. The new findings show that children do not acquire an understanding of beliefs, and hence a representational theory of mind, until after 6 years of age, or 2 years later than most developmental psychologists have concluded. This raises the question of how to interpret other new findings that infants are able to pass false belief tasks. We review these new infant studies, as well as recent studies on chimpanzees, in light of older children’s failure on true belief tasks, and end with some speculation about how all of these new findings might be reconciled.

This paper critically examines currently influential transparency accounts of our knowledge of our own beliefs that say that self-ascriptions of belief typically are arrived at by “looking outward” onto the world. For example, one version of the transparency account says that one self-ascribes beliefs via an inference from a premise to the conclusion that one believes that premise. This rule of inference reliably yields accurate self-ascriptions because you cannot infer a conclusion from a premise without believing the premise, and (...) so you cannot infer from a premise that you believe the premise unless you do believe it. I argue that this procedure cannot be a source of justification, however, because one can be justified in inferring from p that q only if p amounts to strong evidence that q is true. This is incompatible with the transparency account because p often is not very strong evidence that you believe that p. For example, unless you are a weather expert, the fact that it will rain is not very strong evidence that you believe it will rain. After showing how this intuitive problem can be made precise, I conclude with a broader lesson about the nature of inferential justification: that beliefs, when justified, must be underwritten by beliefs, when justified, must be underwritten by evidential relationships between the facts or propositions which those beliefs represent.

ABSTRACTWhat conditions must be satisfied if a group is to count as having a justified belief? Jennifer Lackey has recently argued that any adequate account of group justification must be sensitive to both the evidence actually possessed by enough of a group's operative members as well as the evidence those members should have possessed. I first draw attention to a range of objections to Lackey's specific view of group justification and a range of concrete case intuitions any plausible (...) view of group justification must explain. I then offer an alternative view of group justification where the basic idea is that group justification is a matter of groups responsibly responding to their total evidence. This view both avoids the problems facing Lackey's account and also explains the relevant concrete case intuitions. (shrink)

In his dialogue, 'Non posse suaviter vivi secundum Epicurum', Plutarch of Chaeronea criticizes Epicurus for not believing that the gods are provident over human affairs and for not believing that our souls survive death. However, Plutarch’s arguments are striking in that they do not offer any theoretical justification for believing either of these religious claims to be true; rather, they aim to establish that we are practically justified in adopting them if we follow Epicurus’s rule that the goal (...) of belief is not truth in its own right, but mental tranquility. I argue that this form of argument assumes a novel justificatory theory of religious belief, based in Epicurean thought, that I call ‘strong doxastic hedonism.’. (shrink)

The aim of this essay is to show that Yann Martel’s Life of Pi can be read as illustrating what philosophers usually name as pragmatic arguments for religious belief. Ultimately, this seems to be the reason why, in the short prologue that accompanies the novel, Martel claims Life of Pi to be “a story to make you believe in God”. To put it briefly, these arguments claim that even conceding that the question of whether to believe that God exists (...) or that He does not exist cannot be decided upon the evidence we have, we are still justified to decide to believe in God because of the practical beneficial consequences this belief will bring to us. In Martel’s Life of Pi it is this kind of pragmatic reasoning that originates and what makes the “story with animals” preferable over the “story without animals.” I also point out that these arguments appear more convincing if they are not understood as referring to belief in the ordinary and common usage of the term, as the acceptance as being true the factual claim that the world is such that God does actually exist, but as referring to a subjective, non-truth-dependent way of understanding the world and of relating to it. I show that this is precisely the kind of conception of religious faith that is illustrated by the character of Pi through the novel. (shrink)

My aim in this paper is to critically assess two opposing theses about the epistemology of religious belief. The first one, developed by John Mackie, claims that belief in God can be justified or warranted only if there is a good argument for the existence of God. The second thesis, elaborated by Alvin Plantinga, holds that even if there is no such argument, belief in God can be justified or warranted. I contend that the first (...) thesis is plausibly false, because belief in God is not just like a scientific hypothesis, and the second thesis is likely true if epistemic externalism is the correct view. However, even if the second thesis is true, I argue that to work on good arguments for God’s existence is unavoidable in order to cope with a new version of the Great Pumpkin objection, as well as to achieve other relevant purposes such as to convince rational observers outside the theistic community that belief in God is likely justified or warranted.

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.

“Gettier cases” have played a major role in Anglo-American analytic epistemology over the past fifty years. Philosophers have grouped a bewildering array of examples under the heading “Gettier case.” Philosophers claim that these cases are obvious counterexamples to the “traditional” analysis of knowledge as justified true belief, and they treat correctly classifying the cases as a criterion for judging proposed theories of knowledge. Cognitive scientists recently began testing whether philosophers are right about these cases. It turns out (...) that philosophers were partly right and partly wrong. Some “Gettier cases” are obvious examples of ignorance, but others are obvious examples of knowledge. It also turns out that much research in this area of philosophy is marred by experimenter bias, invented historical claims, dysfunctional categorization of examples, and mischaracterization by philosophers of their own intuitive judgments about particular cases. Despite these shortcomings, lessons learned from studying “Gettier cases” are leading to important insights about knowledge and knowledge attributions, which are central components of social cognition.

This paper argues against the almost universally held view that truth is an instrumentally valuable property of beliefs. For truth to be instrumentally valuable in the way usually supposed, it must play a causal role in the satisfaction of our desires. As it happens, truth can play no such role, because it is screened off from causal relevance by some of the truth-like properties first discussed by Stephen Stich. Because it is not causally relevant to the success of our actions, (...) truth is not instrumentally valuable in the way usually supposed. (shrink)

The Proper Functionist account of warrant – like many otherexternalist accounts – is vulnerable to certain Gettier-style counterexamples involving accidentally true beliefs. In this paper, I briefly survey the development of the account, noting the way it was altered in response to such counterexamples. I then argue that Alvin Plantinga's latest amendment to the account is flawed insofar as it rules out cases of true beliefs which do intuitively strike us as knowledge, and that a conjecture recently put (...) forward by Thomas Crisp is also defective. I conclude by presenting my own suggestion as to how the account can be made less vulnerable to counterexamples involving accidentally true beliefs. Although I stay within the confines of Proper Functionism here, I think that my proposal (modulo a few details) could be attached to other externalist accounts of warrant as well. -/- . (shrink)

This paper examines a passage in the Theaetetus where Plato distinguishes knowledge from true belief by appealing to the example of a jury hearing a case. While the jurors may have true belief, Socrates puts forward two reasons why they cannot achieve knowledge. The reasons for this nescience have typically been taken to be in tension with each other . This paper proposes a solution to the putative difficulty by arguing that what links the two cases (...) of nescience is that in neither case do the jurors act from an epistemic virtue and that doing so is a necessary condition of knowledge. Appreciating that it is a necessary condition of knowledge that it be the result of an epistemic agent's agency in a distinctive way provides a satisfying solution to the difficulty Burnyeat detected and also does justice to an otherwise neglected aspect of Plato's epistemology: his talk of cognitive capacities and virtues and his focus on what it is that is active and passive in epistemic processes.

A standard view in the epistemology of imagination is that imaginings can either provide justification for modal beliefs about what is possible (and perhaps counterfactual conditionals too), or no justification at all. However, in a couple of recent articles, Kind (2016; Forthcoming) argues that imaginings can justify empirical belief about what the world actually is like. In this article, I respond to her argument, showing that imagination doesn't provide the right sort of information to justify empirical belief. Nevertheless, (...) it can help us take advantage of justification that we already have, thereby enabling us to form new doxastically justified beliefs. More specifically, according to the view I advocate, imagination can contribute to one's satisfaction of the proper basing condition – which turns propositional justification into doxastic justification – but without conferring any new justification that the subject isn't already in possession of upon their beliefs. Very little attention has been devoted to the distinction between propositional and doxastic justification in the literature on imagination, and the view I here argue for takes up a yet-to-be occupied position.

The paper begins by reviewing two problems for fallibilism: the lottery problem, or the problem of explaining why fallible evidence, though otherwise excellent, is not enough to know that one will lose the lottery, and Gettier problems. It is then argued that both problems can be resolved if we note an important illocutionary force of knowledge attributions: namely, that when we attribute knowledge to someone we mean to give the person credit for getting things right. Alternatively, to say that a (...) person knows is to say that she got things right due to her own abilities, efforts and actions, rather than due to dumb luck, or blind chance, or something else.

ABSTRACT Drawing inspiration from Fred Dretske, L. S. Carrier, John A. Barker, and Robert Nozick, we develop a tracking analysis of knowing according to which a true belief constitutes knowledge if and only if it is based on reasons that are sensitive to the fact that makes it true, that is, reasons that wouldn’t obtain if the belief weren’t true. We show that our sensitivity analysis handles numerous Gettier-type cases and lottery problems, blocks pathways leading (...) to skepticism, and validates the epistemic closure thesis that correct inferences from known premises yield knowledge of the conclusions. We discuss the plausible views of Ted Warfield and Branden Fitelson regarding cases of knowledge acquired via inference from false premises, and we show how our sensitivity analysis can account for such cases. We present arguments designed to discredit putative counterexamples to sensitivity analyses recently proffered by Tristan Haze, John Williams and Neil Sinhababu, which involve true statements made by untrustworthy informants and strange clocks that sometimes display the correct time while running backwards. Finally, we show that in virtue of employing the paradox-free subjunctive conditionals codified by Relevance Logic theorists instead of the paradox-laden subjunctive conditionals codified by Robert Stalnaker and David Lewis.

Veritism claims that only true beliefs are of basic epistemic value. Michael DePaul argues that veritism is false because it entails the implausible view that all true beliefs are of equal epistemic value.

I argue that neither of the two replies is successful. I propose a new response to DePaul's argument and defend my (...) response against a possible objection. (shrink)

In this paper, we contend that the “Smith case” in Gettier’s attempt to refute the justified true belief (JTB) account of knowledge does not work. This is because the said case fails to satisfy the truth condition, and thus is not a case of JTB at all. We demonstrate this claim using the framework of Donnellan’s distinction between the referential and attributive uses of definite descriptions. Accordingly, the truth value of Smith’s proposition “The man who will get (...) the job has ten coins in his pocket” partly depends on how Smith uses the definite description “the man who will get the job” when he utters the proposition. Since, upon uttering the proposition, Smith has in mind a particular individual, namely Jones, and not just whoever will fit the attribute specified in the definite description, Smith uses the definite description referentially. And so when it turns out that it is Smith who eventually gets the job, the definite description fails to refer to Jones as intended by Smith, thereby making Smith’s proposition false. To think that Smith’s proposition is still true, in this regard, is to use the definite description attributively—that it is about whoever will fit the definite description. Apparently, when Gettier claims that Smith’s proposition is still true, to demonstrate that it is a case of JTB, he, in effect, imposes his attributive understanding of Smith’s usage of the definite description on Smith’s own epistemic situation.

The most pressing difficulty coherentism faces is, I believe, the problem of justified inconsistent beliefs. In a nutshell, there are cases in which our beliefs appear to be both fully rational and justified, and yet the contents of the beliefs are inconsistent, often knowingly so. This fact contradicts the seemingly obvious idea that a minimal requirement for coherence is logical consistency. Here, I present a solution to one version of this problem.

Gettier’s paper, “Is Justified True Belief Knowledge?,” is widely taken to be a paradigm example of the sort of philosophical methodology that has been so hotly debated in the recent literature. Reflection on it motivates the following four theses about that methodology: (A) Intuitive judgments form an epistemically distinctive kind. (B) Intuitive judgments play an epistemically privileged role in philosophical methodology. (C) If intuitive judgments play an epistemically privileged role in philosophical methodology, then their role is to (...) be taken as given inputs into generally accepted forms of reasoning. (D) Philosophical methodology is reasonable. Negative experimental philosophers have empirically challenged (D). Radical responses to their challenge include Williamson’s rejection of (A) and Cappelen and Deutsch’s rejection of (B). Here I follow traditionalists in maintaining (A), (B), and (D), but suggest questioning (C), which has largely been taken as a fixed point in the literature. (shrink)

In “Is Justified True Belief Knowledge?” Edmund Gettier (1963) attacked the thesis ‘S knows that P iff P is true, S believes that P, and S is justified in believing that P’. His intention was to sustain that someone can have a justified true belief without knowing that belief. He made that by creating two counter-examples to that thesis. In this article, I try to show that Gettier’s arguments are based in (...) a weak account of justification, and that such a weak view cannot talk about someone knowing something. I begin by presenting his counter-examples, and then I show they do not work. (shrink)

Moti Mizrahi argues that Gettier cases are unsuccessful counterexamples to the traditional analysis of knowledge (TAK) because such cases inadequately reveal epistemic failures of justified true belief (JTB); and because Gettier cases merely demonstrate semantic inadequacy, the apparent epistemic force of Gettier cases is misleading. Although Mizrahi claims to have deflated the epistemic force of Gettier cases, I will argue that the presence of semantic deficiency in Gettier cases neither requires nor indicates the denial of the epistemic (...) force of those cases. I will provide an extracted version of Mizrahi’s argument, which I believe to be most charitable to his motivation. Then I will offer a counterexample to a pivotal premise in Mizrahi’s argument, ultimately rendering the argument unsound. Finally, upon the examination of a plausible objection, I conclude that Gettier cases are epistemically sustained. (shrink)

In “Process Reliabilism and the Value Problem” I argue that Erik Olsson and Alvin Goldman's conditional probability solution to the value problem in epistemology is unsuccessful and that it makes significant internalist concessions. In “Kinds of Learning and the Likelihood of Future True Beliefs” Olsson and Martin Jönsson try to show that my argument does “not in the end reduce the plausibility” of Olsson and Goldman's account. Here I argue that, while Olsson and Jönsson clarify and amend the conditional (...) probability approach in a number of helpful ways, my case against it remains intact. I conclude with a constructive proposal as to how their account may be steered in a more promising direction. (shrink)

First, ‘Is Justified True Belief Knowledge’ is imprecise but Gettier is explicit that ‘know’ is analysed as the definiendum is ‘S knows that P’. Second, Gettier does not misrepresent as Plato’s definition as the expressions used are ‘Plato considers’ and ‘seems to accept’. Third, Gettier is not mistaken to apply Plato’s definition to propositions since propositional knowledge is a species of Plato’s definition. Fourth, for Plato true belief temporally precedes an account. ‘Jones owns a Ford’ (...) is never a true opinion, hence no account for it can be given. The counterexample is reconstructed with temporality built into it. Fifth, Gettier does not fail to establish the equivalence of ‘believe’, ‘accepts’ and ‘sure’ in the three versions as this is implicitly established in the shifts made in the paper. Sixth, ‘entails’ logically is used only when the entailing proposition is true, but in the counterexamples a false proposition is taken to imply a true one. ‘Entail’ is to be taken in the ordinary sense of implies. Seventh, in Case I, the implication is preserved with the proper representation: → [Gy ↔ ], which implies { → [Gy ↔ ]}’. Eighth, the counterexample is reworked to avoid the objection that justification for p and justification for q may not be sufficient justification for ‘p & q’. (shrink)

In this paper I suggest an account of knowledge by adding a fourth condition to the traditional analysis in terms of justified true belief. I am going to make a first proposal ruling out the Gettier-counterexamples.1 This proposal will then be corrected in the light of other counterexamples. The final analysis will be a combination of a justified-true-belief-account and a causal account of knowledge. Some philosophers have disputed that Gettier‟s examples must be accepted as (...) refutations of the justified true belief analysis of knowledge.2 Their rejection rests on declining a principle underlying Gettier‟s reasoning, namely – as Thalberg calls it – the principle of deducibility of justification (PDJ). PDJ reads as following: For any proposition p, if a person S is justified in believing p, and p entails q, and S deduces q from p and accepts q as a result of this deduction, then S is justified in believing q. This principle allows, for example, the move in Gettier‟s first example from the proposition a) “Jones is the man who will get the job and Jones has ten coins in his pocket” to proposition b) “The man who will get the job has ten coins in his pocket”. 1.

Intuitively, Gettier cases are instances of justified true beliefs that are not cases of knowledge. Should we therefore conclude that knowledge is not justified true belief? Only if we have reason to trust intuition here. But intuitions are unreliable in a wide range of cases. And it can be argued that the Gettier intuitions have a greater resemblance to unreliable intuitions than to reliable intuitions. Whats distinctive about the faulty intuitions, I argue, is that respecting (...) them would mean abandoning a simple, systematic and largely successful theory in favour of a complicated, disjunctive and idiosyncratic theory. So maybe respecting the Gettier intuitions was the wrong reaction, we should instead have been explaining why we are all so easily misled by these kinds of cases. (shrink)
