Defining Knowledge, Misc

Justification has long been considered a necessary condition for knowledge, and theories that deny the necessity of justification have been dismissed as nonstarters. In this chapter, we challenge this long-standing view by showing that many of the arguments offered in support of it fall short and by providing empirical evidence that individuals are often willing to attribute knowledge when epistemic justification is lacking.

Those defending non-factivity of knowledge should explain why it is so intuitive that knowledge entails truth. One option they have is to concede a great deal to this intuition: they can maintain that we know that knowledge is factive, even though it is not.

Whether some condition is equivalent to a conjunction of some (sub-) conditions has been a major issue in analytic philosophy. Examples include: knowledge, acting freely, causation, and justice. Philosophers have striven to offer analyses of these, and other concepts, by showing them equivalent to such a conjunction. Timothy Williamson offers a number of arguments for the idea that knowledge is ‘prime’, hence not equivalent to or composed by some such conjunction. I focus on one of his arguments: the requirement that (...) such conjuncts must be freely recombinable. Although there has been a great deal of discussion of Williamson’s arguments, the flaw I describe has gone unnoticed. Williamson’s argument is expressed in terms of conditions, and cases of the condition. Does the condition include specific information, or is the specific information only part of the case? His argument equivocates between more and less general specifications of the conditions. Once this distinction is clarified, his argument can be seen to be vitiated by this conflation. Neither option yields a sound argument for Williamson’s desired conclusion. (shrink)

In his recent Philosophers’ Imprint paper “The (mostly harmless) inconsistency of knowledge attributions” [Weiner, 2009], Matt Weiner argues that the semantics of the expression “knows that”, as it is used in attributions of knowledge like “Hannah knows that the bank will be open,” are inconsistent, but that this inconsistency is “mostly harmless.” He presents his view as an alternative to the invariantist, contextualist and relativist approaches currently prevalent in the literature, (e.g. [Stanley, 2005], [DeRose, 1995], [Hawthorne, 2006], [MacFarlane, 2005]) and (...) argues that it avoids important disadvantages of each. Yet in calling the supposed inconsistency of knowledge attributions “mostly harmless”, Weiner implies that his view does not have new disadvantages of its own. My purpose in the present paper is to argue that the inconsistency and harmlessness theses cannot be jointly maintained: if we accept that the semantics of ‘know’—or indeed any word—are inconsistent, then we face a dilemma: one horn is dialetheism, the view that there there are true contradictions, the other is the view that that semantic competence in English requires belief in, or similar commitment to, falsehoods. I will argue that neither of these options is well described as “mostly harmless.” The paper is structured as follows: in the first part I present Weiner’s view and his arguments for it. Then in section 2 I compare the question of whether the semantics of ‘knows that’ are inconsistent to the much older controversy over whether the semantics of the expression ‘is true’ are inconsistent. In section 3 I will present Hans Herzberger’s arguments from the 1960s for thinking that no expression in a natural language can have inconsistent semantics. Finally, in section 4 I argue that although Herzberger’s argument seems anachronistic today, both contemporary ways of avoiding his conclusion have significant disadvantages. (shrink)

This is a reply to Howard Sankey’s comment (“Factivity or Grounds? Comment on Mizrahi”) on my paper, “You Can’t Handle the Truth: Knowledge = Epistemic Certainty,” in which I present an argument from the factivity of knowledge for the conclusion that knowledge is epistemic certainty. While Sankey is right that factivity does not entail epistemic certainty, the factivity of knowledge does entail that knowledge is epistemic certainty.

An overview of Quine's understanding of the analytic/synthetic distinction, especially as it is conveyed in his paper, "The Two Dogmas of Empiricism.".

Hume and Quine argue that human beings do not have access to general knowledge, that is, to general truths . The arguments of these two philosophers are premised on what Jaakko Hintikka has called the atomistic postulate. In the present work, it is shown that Hume and Quine in fact sanction an extreme version of this postulate, according to which even items of particular knowledge are not directly accessible in so far as they are relational. For according to their fully (...) realized systems, human beings do not initially perceive any relations, or similar epistemological elements that can associate or combine terms on which a relational or general knowledge claim may be based. Nor, likewise, do human beings perceive the relations or the associations themselves as separate entities. ;In Chapters 1 and 2, respectively, it is shown precisely why Hume and Quine deny that human beings initially perceive either such associative elements or associations in general. Concomitantly, it is made clear why Hume's and Quine's respective epistemologies preclude human beings from initially apprehending not only general knowledge, but particular relational knowledge as well. But this is not to say that Hume and Quine do not think we can eventually acquire such associative elements and correspondingly, knowledge. Rather, Hume and Quine do provide an account of knowledge, but one that holds all relational and connective elements to be constructed by the human mind. In Hume's case, they are constructed by the imagination. In Quine's case, we are never told quite how this construction occurs, although the evidence suggests that Quine implicitly relies on a faculty similar to Hume's imagination. ;In the final chapter of this thesis, it is argued that both Hume and Quine must be read as philosophers who justify knowledge by reducing its possibility to a psychological faculty of construction, as well as to a few concepts of intuitively grasped relations. By way of conclusion, it is shown that this makes Quine's naturalism the psychological heir to Carnap's Aufbau. (shrink)

In his 1967 paper 'A Causal Theory of Knowing', Alvin Goldman sketched an account of empirical knowledge in terms of appropriate causal connections between the fact known and the knower's belief in that fact. This early causal account has been much criticized, even by Goldman himself in later years. We argue that the theory is much more defensible than either he or its other critics have recognized, that there are plausible internal and external resources available to it which save it (...) from many objections in the literature.

El término “conocimiento” y la disciplina filosófica que lo estudia —la teoría del conocimiento— han experimentado notables cambios hasta el presente. La teoría clásica concibe el conocimiento en íntima unión con la verdad, como una captación intelectual de realidades necesarias e inmutables. Con la llegada de la modernidad, la difusión de un clima escéptico puso en duda esta pretensión, cuestionando la aptitud misma del conocimiento para la verdad. Esta duda ha presidido toda la modernidad hasta el presente. Para responder al (...) desafío escéptico, las principales corrientes de la llamada epistemología analítica contemporánea han intentado, sin éxito, explorar el carácter justificante del conocimiento. En este intento, han destacado teorías encaminadas a mostrar que el conocimiento recibe su justificación desde un fundamento, como el fundacionismo y el coherentismo; teorías encaminadas a mostrar que el conocimiento recibe su justificación desde sus fuentes, como el externismo y el internismo; y teorías encaminadas a mostrar que la recibe por las facultades cognitivas mismas como instrumentos de conocimiento fiables, como la epistemología de la virtud. Todas ellas generan, a su vez, nuevas paradojas e imponen la necesidad de volver a los fundamentos de esta disciplina, presentes en la teoría clásica, para descubrir la conexión entre conocimiento y verdad, e intentar detener el desafío escéptico.

У статті проаналізовано категорію дикості в поезії Олега Лишеги. Екокритична категорія дикості – як протилежність до цивілізованого, обжитого, людського – дає змогу окреслити основні ознаки лісу у поезії Лишеги як дикого, непередбачуваного, тваринного, магічного простору. Близька взаємодія суб’єкта лірики із лісовим ландшафтом створює глибшу ідентичність дикого лісу, який, отримавши голос, промовляє у тексті. Надзвичайно важливим для поета є збереження неприрученості, гармонійне співіснування світу природи і світу людей.

Modal epistemic conditions have played an important role in post-Gettier theories of knowledge. These conditions purportedly eliminate the pernicious kind of luck present in all Gettier-type cases and offer a rather convincing way of refuting skepticism. This motivates the view that conditions of this sort are necessary for knowledge. I argue against this. I claim that modal conditions, particularly sensitivity and safety, are not necessary for knowledge. I do this by noting that the problem cases for both conditions point to (...) a problem that cannot be fixed even by a revised similarity ranking or ordering of worlds. I offer as groundwork a set theoretical analysis of the profiles of the problem cases for safety and sensitivity. I then demonstrate that these conditions fail whenever necessary links constitutive of the epistemic situation actually obtain but are not modally preserved. (shrink)

Knobe (2003a, 2003b, 2004b) and others have demonstrated the surprising fact that the valence of a side-effect action can affect intuitions about whether that action was performed intentionally. Here we report the results of an experiment that extends these findings by testing for an analogous effect regarding knowledge attributions. Our results suggest that subjects are less likely to find that an agent knows an action will bring about a side-effect when the effect is good than when it is bad. It (...) is further argued that these findings, while preliminary, have important implications for recent debates within epistemology about the relationship between knowledge and action. (shrink)

John N. Williams argued that Peter Klein's defeasibility theory of knowledge excludes the possibility of one knowing that one has a posteriori knowledge. He does that by way of adding a new twist to an objection Klein himself answered more than forty years ago. In this paper I argue that Williams' objection misses its target because of this new twist.

Fallibilism is ubiquitous in contemporary epistemology. I argue that a paradox about knowledge, generated by considerations of truth, shows that fallibilism can only deliver knowledge in lucky circumstances. Specifically, since it is possible that we are brains‐in‐vats, it is possible that all our beliefs are wrong. Thus, the fallibilist can know neither whether or not we have much knowledge about the world nor whether or not we know any specific proposition, and so the warrant of our knowledge‐claims is much reduced (...) and second‐order skepticism is generated. Since this is the case in both skeptical and everyday contexts, contextualism cannot resolve the paradox. (shrink)

The 'Gettier Problem' has been central to epistemology since 1963, when Edmund Gettier presented a powerful challenge to the standard analysis of knowledge. Now twenty-six leading philosophers examine the issues that arise from Gettier's challenge, setting the agenda for future work on the central problem of epistemology.

The ambiguity theory of ‘knows’ is the view that ‘knows’ and its cognates have more than one propositional sense – i.e. more than one sense that can properly be used in ‘knows that’ etc. constructions. Given that most of us are ‘intuitive invariantists’ – i.e. most of us initially have the intuition that ‘knows’ is univocal – defenders of the ambiguity theory need to offer an explanation for the semantic blindness present if ‘knows’ is in fact ambiguous. This paper is (...) an attempt to offer such an explanation. Section 1 contains a general argument for the ubiquity of semantic blindness for ambiguous; the upshot being that semantic blindness for the ambiguity of ‘knows’ is thus unsurprising. Section 2 offers more specific arguments for why ‘knows’ is the type of ambiguous word that we’re very unlikely to quickly recognize is ambiguous. (shrink)

Epistemology for the Rest of the World. Edited by Mizumoto Masaharu, Stich Stephen, McCready Eric.

The generality problem is one of the most pressing challenges for reliabilism. The problem begins with this question: of all the process types exemplified by a given process token, which types are the relevant ones for determining whether the resultant belief counts as knowledge? As philosophers like Earl Conee and Richard Feldman have argued, extant responses to the generality problem have failed, and it looks as if no solution is forthcoming. In this paper, I present a new response to the (...) generality problem that illuminates the nature of knowledge-enabling reliability. My response builds upon the insights of Juan Comesaña’s well-founded solution to the generality problem, according to which relevant types are content–evidence pairs, i.e., descriptions of both the target belief’s content and the evidence on which the belief was based. While most responses to the generality problem, including Comesaña’s, only posit one relevant type for any given process token, I argue that knowledge-enabling reliability requires a process token to be reliable with respect to multiple content–evidence pairs, each with varying degrees of descriptive specificity. I call this solution multi-type evidential reliabilism. After offering a clear formulation of MTE, I conclude by arguing that MTE is sufficiently informative to rebut Conee and Feldman’s generality problem objection to a reliability condition on knowledge.

Evidentialism has shown itself to be an important research program in contemporary epistemology, with evidentialists giving theories of virtually every important topic in epistemology. Nevertheless, at the heart of evidentialism is a handful of concepts, namely evidence, evidence possession, and evidential fit. If evidentialists cannot give us a plausible account of these concepts, then their research program, with all its various theories, will be in serious trouble. In this paper, I argue that evidentialists has yet to give a plausible account (...) of evidence possession and the prospects for doing so are dim. (shrink)

Here is a definition of knowledge: for you to know a proposition p is for you to have an outright belief in p that is correct precisely because it manifests the virtue of rationality. This definition resembles Ernest Sosa’s “virtue theory”, except that on this definition, the only virtue that must be manifested in all instances of knowledge is rationality, and no reductive account of rationality is attempted—rationality is assumed to be an irreducibly normative notion. This definition is compatible with (...) “internalism” about rationality, and with a form of “pragmatic encroachment” on the conditions of rational outright belief. An interpretation is given of this definition, and especially of the sense of ’because’ that it involves. On this interpretation, this definition entails that both safety and adherence are necessary conditions on knowledge; it supports a kind of contextualism about terms like ‘knowledge’; and it provides resources to defend safety, adherence, and contextualism, against some recent objections. (shrink)

I argue that S knows that p implies that S is properly committed to the truth of p, not that S believes that p. Belief is not required for knowledge because it is possible that one could know that there are no beliefs. Being ‘properly committed’ to the truth of a proposition is a matter of having a certain normative status, not occupying a particular psychological state. After arguing that knowledge requires commitment instead of belief, I go on to demonstrate (...) the theoretical utility of this hypothesis. (shrink)

Even though both Dewey and Wittgenstein have been rightly classified as both being ‘pragmatist’ thinkers in a broad sense, they stand in stark contrast with respect to their writing style and their general attitude towards the future of western civilization. This article reflects these differences and traces them back to their diverging conceptions of knowledge. Dewey criticizes the philosophical tradition for erecting an artificial barrier between theory and practice, but he retains the traditional high esteem for knowledge by re-describing it (...) as practical inquiry. Consequently, all practically acquired beliefs and certainties are either justified or a potential subject-matter for further inquiries. Wittgenstein, on the other hand, shows the limitation of the very idea of knowledge by pointing to the knowing subject’s fragile relation to its own lived practices. He claims that there are practically acquired beliefs and certainties which are out of reach for the inquiring subject. Thus, the seemingly superficial divergence in style and method shows to be grounded in far-reaching philosophical differences. (shrink)

During the last decades, knowledge has attracted the greatest attention in a growing number of disciplines, generating a deluge of literature. However, it has yet to become the object of a fully established sociology of knowledge able to fulfil the challenges of present society, often called the knowledge-society. We posit knowledge as a basis on which to model social life, proposing a three-dimensional approach to social reality (i.e., individuals, social aggregates, knowledge). Looking at knowledge as at ‘a cooperative good’ and (...) a communicative process, we then apply the same three dimensions to knowledge itself as a sociological production, ending up with a typology encompassing three knowledge families (intellectual, practical and objectified) and three ways of access (direct personal knowing, indirect social acquaintance, externally recognised and personally introjected acknowledge). Steps towards a theory of knowledge-society are then proposed. (shrink)

It is often claimed that Plato’s definition of knowledge as “true opinion with an account” is in agreement with the contemporary analysis of knowledge as “justified true belief”. Some scholars disagree with the attribution of JTB to Plato. I analyze three influential arguments against the assumption of Plato’s agreement with JTB, and refute them. Then I provide my own argument against the assumption. I argue that the contemporary interpretation of the JTB formula understands “belief” not in the sense of an (...) “opinion,” but rather of a “degree of confidence.” Accordingly, “justification” is understood not as applying to the opinion itself, but rather to the person having a certain degree of confidence. I support this claim by showing the difference between the traditional and the contemporary understanding of “evidence,” the former referring to a property of the proposition, while the latter meaning the body of reasons, which supports the person’s confidence to a certain degree. Thus, I conclude that Plato understands knowledge as “correct opinion validated by a rational explanation,” and it has very little in common with the contemporary understanding of knowledge as “sufficiently supported subjective degree of confidence in the truth of a proposition.”.

The most comprehensive manifestation of language can be seen in the activity of speaking. In it the activity of speaking cannot be understood unless it is referred to the concepts of language and a language. Anything in language can be found in the activity of speaking. Because of this you can find what language is if you abstract from the innumerable manifestations of the activity of speaking.

Hume held that we have no rational justification for our inductive beliefs. A more radical view is that we have no rational justification for any of our beliefs. This dissertation has two goals pertaining to this more radical view. // The first goal is to find a basis for constructive epistemology that is consistent with this view. This goal is first sought by considering externalist theories of knowledge since these do not require rational justification for knowledge. Externalist theories are defended (...) against the usual objections, partly via a strategy of immunizing them from counterexample-based objections by arguing that epistemologies can be successful even if they fail to explicate ordinary epistemic notions. But a new objection to externalist theories is then brought to light. The objection begins as an attack against a dogma of contemporary epistemology, that the chief benefit of possessing knowledge is having a true belief. It is argued that there are many other benefits to having knowledge , and that externalist theories are defective because externalist knowledge lacks these benefits. A mixed internalist/externalist theory, bilevel reliabilism, is then presented as a solution to this difficulty. //The second goal is to provide an explanation of the function and origin of human epistemic practices that is consistent with the no-rational-justification view. Providing such an explanation is problematic for holders of this view because, if it is correct, it seems, prima facie, that there is no reason to have epistemic practices. This goal is achieved by arguing that epistemic practices, despite appearing to have rational justification as their goal, chiefly function to promote the existence of bilevel reliabilist knowledge, a very useful type of belief that is not rationally justified. It is then argued that the explanation of the origin of epistemic practices is that they arise from natural human inductive tendencies. (shrink)

The overall goal of this paper is to apply Hintikka’s Socratic Epistemology to Gettier’s counterexamples to the tripartite definition of knowledge as justified true belief. In the process, I will make full use of Socratic Epistemology’s methodology and commitments. This includes, among other things, looking at Gettier’s counterexamples as games between an Inquirer and Nature (the source of information), as well as treating the items in them as pieces of information. The strategy that I employ in this paper also makes (...) use of frames (or partitions). One of the important results of this paper is a scenario where Gettier cannot setup the dilemma for the tripartite definition of knowledge. (shrink)

Duncan Pritchard’s book (Epistemic Luck, Oxford University Press, 2005) concerns the interplay between two disturbing kinds of epistemic luck, termed “reflective” and “veritic,” and two types of arguments for skepticism, one based on a closure principle for knowledge and the other on an underdetermination thesis about the quality of our evidence for the everyday propositions we believe. Pritchard defends the view that a safety-based account of knowledge can answer the closure argument and provide an account of how veritic epistemic luck (...) is eliminated. He also argues that reflective epistemic luck cannot be eliminated, and that even though it is the sort of luck with which the underdetermination argument is concerned, the fact that this type of luck cannot be eliminated doesn’t undermine knowledge. Instead, it undermines the assertibility of our knowledge, at least in skeptical contexts. So when the skeptic challenges the idea that we know using the underdetermination principle, we have no legitimate response to offer, and it is this fundamental fact of epistemic life that Pritchard terms our inevitable epistemic angst.

In this paper I will offer a comprehensive defense of the safety account of knowledge against counterexamples that have been recently put forward. In section 1, I will discuss different versions of safety, arguing that a specific variant of method-relativized safety is the most plausible. I will then use this specific version of safety to respond to counterexamples in the recent literature. In section 2, I will address alleged examples of safe beliefs that still constitute Gettier cases. In section 3, (...) I will discuss alleged examples of unsafe (and in this sense lucky) knowledge. In section 4, I will address alleged cases of safe belief that do not constitute knowledge for non-Gettier reasons. My overall goal is to show that there are no successful counterexamples to robust anti-luck epistemology and to highlight some major presuppositions of my reply. (shrink)

This French paper is a prelimary report on the authors' work on the logics of common knowledge and common belief. See L. Lismont and P. Mongin, "On the logic of common belief and common knowledge", Theory and Decision 37 (1): 75-106. 1994 for a more complete report.

The paper surveys the currently available axiomatizations of common belief (CB) and common knowledge (CK) by means of modal propositional logics. (Throughout, knowledge- whether individual or common- is defined as true belief.) Section 1 introduces the formal method of axiomatization followed by epistemic logicians, especially the syntax-semantics distinction, and the notion of a soundness and completeness theorem. Section 2 explains the syntactical concepts, while briefly discussing their motivations. Two standard semantic constructions, Kripke structures and neighbourhood structures, are introduced in Sections (...) 3 and 4, respectively. It is recalled that Aumann's partitional model of CK is a particular case of a definition in terms of Kripke structures. The paper also restates the well-known fact that Kripke structures can be regarded as particular cases of neighbourhood structures. Section 3 reviews the soundness and completeness theorems proved w.r.t. the former structures by Fagin, Halpern, Moses and Vardi, as well as related results by Lismont. Section 4 reviews the corresponding theorems derived w.r.t. the latter structures by Lismont and Mongin. A general conclusion of the paper is that the axiomatization of CB does not require as strong systems of individual belief as was originally thought- only monotonicity has thusfar proved indispensable. Section 5 explains another consequence of general relevance: despite the "infinitary" nature of CB, the axiom systems of this paper admit of effective decision procedures, i.e., they are decidable in the logician's sense.

This paper provides an account of how virtue epistemology can accommodate knowledge acquired through testimony and extended cognition. Section 1 articulates the characteristic claim of virtue epistemology, and introduces the issues discussed in the paper. Section 2 details a related pair of objections to VE: that it is unable to accommodate cases of knowledge through testimony and extended cognition. Section 3 reviews two different virtue epistemologies and their responses to these objections presented in Greco :1–26, 2012). Considerations are presented for (...) why both of these accounts and responses are inadequate. Because of this, I suggest that it is unlikely that an analysis of the attribution relation will provide an adequate response to the objections. Section 4 advocates for a revised VE and a different way of dealing with the objections, which accommodates how agents are sometimes epistemically dependent on external sources. The central claim, for which a novel argument is presented, is that in some cases of knowledge the success is attributable to the abilities of an information system of which the knower is a part. This requires an important revision to traditional VE, but the characteristic claim of VE still holds true–every instance of knowledge is an instance of success attributable to ability. Thus, VE’s solutions to problems concerning the nature and value of knowledge are secured. (shrink)

It has been objected recently that naïve realism is inconsistent with an empirically well-supported hypothesis that unconscious perception is possible. Because epistemological disjunctivism is plausible only in conjunction with naïve realism (for a reason I provide), the objection reaches it too. In response, I show that the unconscious perception hypothesis can be changed from a problem into an advantage of epistemological disjunctivism. I do this by suggesting that: (i) naïve realism is consistent with the hypothesis; (ii) the contrast between epistemological (...) disjunctivism and epistemic externalism explains the difference in epistemic import between conscious and unconscious perception.

Peter Baumann develops and defends a distinctive version of epistemic contextualism, the view that the truth conditions or the meaning of knowledge attributions of the form "S knows that p" can vary with the context of the attributor. The first part of the book examines arguments for contextualism and develops Baumann's version. It begins by dealing with the argument from cases and ordinary usage, and then addresses "theoretical" arguments, from reliability and from luck. The second part of the book discusses (...) the problems contextualism faces, to which it must respond, and provides an extension of contextualism beyond epistemology. The third part of the book is focused on some major objections to contextualism and alternative views, namely subject-sensitive invariantism, contrastivism and relativism. (shrink)

In “Beat the (Backward) Clock,” we argued that John Williams and Neil Sinhababu’s Backward Clock Case fails to be a counterexample to Robert Nozick’s or Fred Dretske’s Theories of Knowledge. Williams’ reply to our paper, “There’s Nothing to Beat a Backward Clock: A Rejoinder to Adams, Barker and Clarke,” is a further attempt to defend their counterexample against a range of objections. In this paper, we argue that, despite the number and length of footnotes, Williams is still wrong.

The author of this paper discusses the source experience defined in terms of the ancient Indian philosophy. She focuses on two out of six mainstream Hindu philosophical schools, Sāṃkhya and Yoga. While doing so the author refers to the oldest preserved texts of this classical tradition, namely Yogasūtra c. 3rd CE and Sāṃkhyakārikā 5th CE, together with their most authoritative commentaries. First, three major connotations of darśana, the Sanskrit equivalent of φιλοσοφια, are introduced and contextualised appropriately for the comparative study (...) of source experience. Then, three means of knowledge (pramāṇa-s) as well as the purpose of search for source experience are explained. Next, a specific understanding of source experience in the context of Sāṃkhya-Yoga is discussed to reveal both its contents and the reasons for apophatic formulation of the liberating insight. The self-knowledge and true knowledge both result from source experience based on distinguished discernment (vivekakhyāti) between “I”/ego and the self, gained during the multistage meditative absorption (samādhi). The analysis of discriminative cognition is followed by reconstruction of the arguments offered by the author of Sāṃkhyakārikā in favour of the existence of the self (puruṣa), immutable, inactive, and opposed to the domain of nature (prakṛti) characterised as spontaneously active and creative, which includes empirical consciousness, or “I”. The last section is devoted to the issue of the possible communication of achieved knowledge and its application in the everyday life practice. In conclusion, it is claimed that in Indian philosophy there has been no clear distinction between the practical value of subjective cognitive insight and theoretical ambitions of philosophy, which is why many authors of classical treatises are also recognised as eminent sapiential mentors. Often, especially in the texts of Yoga, Nyāyā and Buddhism philosophy is associated with therapy and philosophical exposition of the “cognitive ailments” is compared to medical treatment. -/- .

The main examples of pragmatic encroachment presented by Jason Stanley involve the idea that knowledge ascription occurs more readily in cases where stakes are low rather than high. This is the stakes hypothesis. In this paper an example is presented showing that in some cases knowledge ascription is more readily appropriate where stakes are high rather than low.

In a recent paper, Tristan Haze offers two examples that, he claims, are counterexamples to Nozick's Theory of Knowledge. Haze claims his examples work against Nozick's theory understood as relativized to belief forming methods M. We believe that they fail to be counterexamples to Nozick's theory. Since he aims the examples at tracking theories generally, we will also explain why they are not counterexamples to Dretske's Conclusive Reasons Theory of Knowledge.

Some philosophers have recently argued that whether a true belief amounts to knowledge in a specific circumstance depends on features of the subject’s practical situation that are unrelated to the truth of the subject’s belief, such as the costs for the subject of being wrong about whether the believed proposition is true. One of the best-known arguments used to support this view is that it best explains a number of paradigmatic cases, such as the well-known Bank Case, in which a (...) difference in knowledge occurs in subjects differing exclusively with respect to their practical situation. I suggest an alternative explanation of such cases. My explanation has a disjunctive character: on the one hand, it accounts for cases in which the subject is aware of the costs of being wrong in a given situation in terms of the influence of psychological factors on her mechanisms of belief-formation and revision. On the other hand, it accounts for cases in which the subject is ignorant of the costs of being wrong in her situation by imposing a new condition on knowledge. This condition is that one knows that p only if one does not underestimate the importance of being right about whether p. I argue that my explanation has a number of advantages over other invariantist explanations: it accounts for all the relevant cases preserving the semantic significance of our ordinary intuitions, it is compatible with an intellectualist account of knowledge and it escapes several problems affecting competing views.

In this paper I defend the view that knowledge is belief for reasons that are both objectively and subjectively sufficient from an important objection due to Daniel Whiting, in this journal. Whiting argues that this view fails to deal adequately with a familiar sort of counterexample to analyses of knowledge, fake barn cases. I accept Whiting’s conclusion that my earlier paper offered an inadequate treatment of fake barn cases, but defend a new account of basic perceptual reasons that is consistent (...) with the account of knowledge and successfully deals with fake barns.

The generality problem is commonly seen as one of the most pressing issues for process reliabilism. The generality problem starts with the following question: of all the process types exemplified by a given process token, which type is the relevant one for measuring reliability? Defenders of the generality problem claim that process reliabilists have a burden to produce an informative account of process type relevance. As they argue, without such a successful account, the reasonability of process reliabilism is significantly undermined. (...) One way for the reliabilist to respond is to attempt to construct such a theory of type relevance. But another way of responding is to argue that, if finding an account of type relevance is a burden for the reliabilist, then it is also a burden for everyone else. Thus, the generality problem doesn’t present some unique reason to reject process reliabilism. I call this latter strategy a parrying response. In this essay, I examine the contemporary parrying responses of Michael Bishop and Juan Comesaña, which have both faced recent criticism. I respond to these critics, and argue that parrying responses are far stronger than defenders of the generality problem have appreciated. (shrink)

Trenton Merricks argues that on any reasonable account, warrant must entailtruth. I demonstrate three theses about the properties ofwarrant: (1) Warrant is not unique;there are many properties that satisfy the definition of warrant. (2) Warrant need not entail truth; there are some warrant properties that entailtruthand others that do not. (3) Warrant need not be closed under entailment, even if knowledge is. If knowledge satisfies closure, then some warrant properties satisfy closure while others do not;if knowledge violates closure, then allwarrant (...) properties violate closure. (shrink)

Perhaps the concept of knowledge, prior to its being fashioned and molded by certain philosophical traditions, never offered any stable negative verdict in the original fake barn case.
