It is a commonplace that in philosophy, intuitions supply evidence for and against philosophical theories. Recent work in experimental philosophy has brought to bear the intuitions of philosophically naïve subjects in a number of different ways. One line of response to this work has been to claim that philosophers have expertise that privileges their intuitive judgments, and allows them to disregard the judgments of non-experts. This expertise is supposed to be analogous to the expertise of the mathematician or the physicist. (...) This paper critically evaluates this appeal to philosophical expertise. (shrink)

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

There is some consensus that for S to know that p, it cannot be merely a matter of luck that S’s belief that p is true. This consideration has led Duncan Pritchard and others to propose a safety condition on knowledge. In this paper, we argue that the safety condition is not a proper formulation of the intuition that knowledge excludes luck. We suggest an alternative proposal in the same spirit as safety, and find it lacking as well.

In The Philosophy of Philosophy, Tim Williamson has offered a sophisticated account of thought experiments and of modal epistemology. More recently, he has also engaged in a variant of the so-called ‘expertise defence’ of traditional philosophical methodology. In this paper I argue that if Williamson’s account of thought experiments and of modal epistemology is right, this seriously undermines his version of the expertise defence.

In the last decade, philosophers have offered a number of proposals concerning the logical form of hypothetical cases, or thought experiments, as these are used for purposes of testing philosophical claims. In this paper, I discuss what the desiderata for a formal proposal are. Employing a comparison with general philosophy of science, I suggest that one important desideratum is to highlight recurrent patterns of disagreement surrounding cases. I advocate a proposal in propositional modal logic which, I argue, better meets this (...) desideratum than competing proposals. I also sketch how this proposal may be extended into more fine grained analyses, employing counterfactual conditionals yet avoiding certain problems due to so-called "deviant realizations". (shrink)

Among the epistemological ideas commonly associated with the Descartes of the Meditations, at any rate, is a knowledge-infallibilism. Such an idea was seemingly a vital element in Descartes’s search for truth within that investigative setting: only a true belief gained infallibly could be knowledge, as the Meditations conceived of this. Contemporary epistemologists are less likely than Descartes was to advocate our ever seeking knowledge-infallibility, if only because most are doubtful as to its ever being available. Still, they would agree—in a (...) seemingly Cartesian spirit—that if infallible knowledge was available then it would be a stronger link to truth than fallible knowledge ever manages to be. But this paper argues that infallible knowledge lacks that supposed advantage over fallible knowledge. Indeed, we will see why we should move even further away from the epistemological model at the heart of the Meditations: we should adopt knowledge-minimalism, by conceiving of a belief’s being true as always sufficient for its being knowledge—this, for any belief.

Taking his conceptual cue from Ernest Sosa, John Turri has offered a putative conceptual solution to the Gettier problem: Knowledge is cognitively adept belief, and no Gettiered belief is cognitively adept. At the core of such adeptness is a relation of manifestation. Yet to require that relation within knowing is to reach for what amounts to an infallibilist conception of knowledge. And this clashes with the spirit behind the fallibilism articulated by Gettier when stating his challenge. So, Turri’s form of (...) response is irrelevant to that challenge, which was intended to pose a conceptual problem within fallibilist conceptions of knowledge. (And that failure on Turri’s part needs to be highlighted to remind epistemologists of the need to assess Gettier cases by a fallibilist standard. Although that need was described earlier by Robert Almeder, apparently his advice is being overlooked. This paper develops it anew, in a more general form.). (shrink)

One of contemporary epistemology's more important conceptual challenges is that of understanding the nature of fallibility. Part of why this matters is that it would contribute to our understanding the natures of fallible warrant and fallible knowledge. This article evaluates two candidates – and describes a shared form of failing. Each is concealedly infallibilist. This failing is all-too-representative of the difficulty of doing justice to the notion of fallibility within the notions of fallible warrant and fallible knowledge. The article ends (...) with a proposal for an improved form of conception of fallible warrant and fallible knowledge. (shrink)

Could the standard interpretation of Gettier cases reflect a fundamental confusion? Indeed so. How well can epistemologists argue for the truth of that standard interpretation? Not so well. A methodological mistake is allowing them not to notice how they are simply (and inappropriately) being infallibilists when regarding Gettiered beliefs as failing to be knowledge. There is no Gettier problem that we have not merely created for ourselves by unwittingly being infallibilists about knowledge.

Norström has argued that contemporary epistemological debates about the conceptual relations between knowledge-that and knowledge-how need to be supplemented by a concept of technological knowledge—with this being a further kind of knowledge. But this paper argues that Norström has not shown why technological knowledge-that is so distinctive because Norström has not shown that such knowledge cannot be reduced conceptually to a form of knowledge-how. The paper thus applies practicalism to the case of technological knowledge-that. Indeed, the paper shows why Norström’s (...) conception of technological knowledge unintentionally strengthens this proposed form of reduction. (shrink)

Can we conceive cogently of all knowledge – in particular, all knowledge of truths – as being knowledge-how? This paper provides reasons for thinking not only that is this possible, but that it is conceptually advantageous and suggestive. Those reasons include adaptations of, and responses to, some classic philosophical arguments and ideas, from Descartes, Hume, Peirce, Mill, and Ryle. The paper’s position is thus a practicalism – a kind of pragmatism – about the nature of knowledge, arguing that all knowledge (...) is knowledge-how to act – to do this, to do that. Such a conception can include, too, a distinctive view of the metaphysical relation between knowledge and belief. We see that, contrary to what most contemporary epistemologists say, knowledge need not be a form of belief. Instead, a belief that p can be a way simply of enriching or strengthening knowledge that p. It can do this in a paracticalist way, by allowing one to do more with the knowledge. (shrink)

Edmund Gettier is Professor Emeritus at the University of Massachusetts, Amherst. This short piece, published in 1963, seemed to many decisively to refute an otherwise attractive analysis of knowledge. It stimulated a renewed effort, still ongoing, to clarify exactly what knowledge comprises.

El artículo propone una concepción no individualista de la justifi cación epistémica de las decisiones judiciales. Sugiere que la epistemología jurídica debe reconsiderar su teoría de la justifi cación epistémica con el fi n de dar cuenta de la posibilidad de que juzgadores racionales carezcan de autonomía intelectual. Sostiene que la dependencia epistémica es una de las propiedades que distinguen el razonamiento jurídico sobre los hechos, y que los juzgadores tienen buenas razones para aceptar una proposición sobre la base de (...) la experiencia cognitiva de otras personas. Después de hacer algunas precisiones terminológicas acerca de los conceptos de “testimonio” y “evidencia”, el trabajo explica la estructura de la dependencia epistémica, aborda los debates normativos actuales acerca de la justifi cación epistémica en casos de testimonio, y propone una posición externalista distinta, el antiindividualismo. Al fi nal, se explora una variación sobre el tema, que consiste en la integración de la noción de dependencia epistémica en una teoría de la autoridad en el derecho. (shrink)

This paper offers a new argument for compatibilism about moral responsibility by drawing attention to some overlooked implications of incompatibilism. More specifically, I argue that incompatibilists are committed to some unsavory claims about pairs of agents in deterministic worlds. These include comparative claims about moral responsibility, blameworthiness, desert, punishment, and the fittingness of reactive attitudes. I argue that we have good reasons to reject such comparisons because they fail to account for key differences between deterministic agents. This provides us with (...) reason to embrace compatibilism and reject incompatibilism. (shrink)

Epistemic logic begins with the recognition that our everyday talk about knowing and believing has some systematic features that we can track and re‡ect upon. Epistemic logicians have studied and extended these glints of systematic structure in fascinating and important ways since the early 1960s. However, for one reason or another, mainstream epistemologists have shown little interest. It is striking to contrast the marginal role of epistemic logic in contemporary epistemology with the centrality of modal logic for metaphysicians. This article (...) is intended to help in correcting this oversight by presenting some important developments in epistemic logic and suggesting ways to understand their applicability to traditional epistemological problems. Obviously, by itself, tweaking the formal apparatus of epistemic logic does not solve traditional epistemological problems. Epistemic logic can help us to navigate through problems in a systematic fashion by unpacking the logic of the problematic concepts, it can also lead us to recognize problems that we had not anticipated. This is basically analogous to the role that modal logic has played in contemporary metaphysics. (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.

Addressing Walter Hopp’s original application of the distinction between agent-fallibility and method-fallibility to phenomenological inquiry concerning epistemic justification, I question whether these are the only two forms of fallibility that are useful or whether there are not also others that are needed. In doing so, I draw my inspiration from Husserl, who in the beginnings of his phenomenological investigations struggled with the distinction between noetic and noematic analyses. For example, in the Preface to the Second Edition of the Logical Investigations (...) he criticizes the First Investigation as having been “one-sidedly” noetically directed and as having thus neglected the noematic aspects of meaning (XVIII 13–14). Also, in an addendum to the Fifth Investigation he notes that in the transition from the First Edition to the Second he has learned to broaden the concept of “phenomenological content” to include not only the “real” ( reell ) contents (noetic, subjective) of consciousness but also the “intentional” (noematic, objective) (XIX/1 411). The fact that, in gradually moving from consciousness (noesis) to what consciousness is of (noema), Husserl struggled with this distinction is an indication of the immensity of the perplexing problems and potential solutions that Hopp has led the phenomenology of knowledge into by introducing his useful notions of agent-fallibility and method-fallibility. Like Husserl, he has focused mainly and mostly on the noetic issues; like Husserl as well, I will try to move step by step from the noetic area into the noematic. I conclude that Hopp’s approach has the potential to become seminal. (shrink)

The 'substitution argument' purports to demonstrate the falsity of Russellian accounts of belief-ascription by observing that, e.g., these two sentences: (LC) Lois believes that Clark can fly. (LS) Lois believes that Superman can fly. could have different truth-values. But what is the basis for that claim? It seems widely to be supposed, especially by Russellians, that it is simply an 'intuition', one that could then be 'explained away'. And this supposition plays an especially important role in Jennifer Saul's defense of (...) Russellianism, based upon the existence of an allegedly similar contrast between these two sentences: (PC) Superman is more popular than Clark. (PS) Superman is more popular than Superman. The latter contrast looks pragmatic. But then, Saul asks, why shouldn't we then say the same about the former? The answer to this question is that the two cases simply are not similar. In the case of (PC) and (PS), we have only the facts that these strike us differently, and that people will sometimes say things like (PC), whereas they will never say things like (PS). By contrast, there is an argument to be given that (LS) can be true even if (LC) is false, and this argument does not appeal to anyone's 'intuitions'. The main goal of the paper is to present such a version of the substitution argument, building upon the treatment of the Fregan argument against Russellian accounts of belief itself in "Solving Frege's Puzzle". A subsidiary goal is to contribute to the growing literature arguing that 'intuitions' simply do not play the sort of role in philosophical inquiry that so-called 'experimental philosophers' have supposed they do.

Beginning with Zagzebski (The Philosophical Quarterly 44:65–73, 1994), some philosophers have argued that there can be no solution to the Gettier counterexamples within the framework of a fallibilist theory of knowledge. If true, this would be devastating, since it is believed on good grounds that infallibilism leads to scepticism. But I argue here that these purported proofs are mistaken and that the truthmaker solution to the Gettier problems is both cogent and fallibilist in nature. To show this I develop the (...) notion of evidence of a state of affairs, a crucial concept in the truthmaker theory. I also argue that a common principle of the transmission of evidence through entailment is false, and the cause of much of the trouble. (shrink)

Edmund Gettier’s paper “Is Justified True Belief Knowledge?” first appeared in an issue of Analysis , dated June of 1963, and although it’s tempting to wax hyperbolic when discussing the paper’s importance and influence, it is fair to say that its impact on contemporary philosophy has been substantial and wide-ranging. Epistemology has benefited from 50 years of sincere and rigorous discussion of issues arising from the paper, and Gettier’s conclusion that knowledge is not justified true belief is sometimes offered as (...) an example of the reality of philosophical progress. However, what can be called the Gettier problem has little to do with the text of the famous paper itself. The importance of the Gettier problem does not depend on the attribution of the tripartite theory of knowledge to Plato, Chisholm, and Ayer, nor on the psychological plausibility of the par ..

Socially extended knowledge has recently received much attention in mainstream epistemology. Knowledge here is not to be understood as wholly realised within a single individual who manipulates artefacts or tools but as collaboratively realised across plural agents. Because of its focus on the interpersonal dimension, socially extended epistemology appears to be a promising approach for investigating the deeply social nature of epistemic practices. I believe, however, that this line of inquiry could be made more fruitful if it is connected with (...) the critical notion of epistemic responsibility, as developed in feminist responsibilism. According to feminist responsibilists, at the core of epistemic responsibility is a critical disposition toward correcting epistemic injustice. This epistemic idea is highly relevant to the epistemological context of illness, where patient testimony is often disregarded. Hence, though restricted to the epistemological context of the experience of illness, this chapter delves into epistemic injustice and its robust mechanisms. I thus explore what responsible epistemic practices should involve in order to redress that injustice and how epistemic responsibility should be socially extended. The discussion proceeds as follows. First, by relying on Arthur Frank’s innovative work on illness narratives, I focus on chaotic bodily messages from patients overwhelmed by suffering and then explain why these messages should count as genuine narratives or testimonies despite their inarticulateness. Second, I elaborate on how epistemic injustice concerning such narratives (i.e., chaos narratives) is produced and reproduced, in particular how both a dominant sociocultural norm and our inherent vulnerability can contribute to its production and reproduction. Finally, I propose an extended form of epistemic responsibility that ameliorates this aspect. Laying particular emphasis on the epistemic role of mature empathy, I characterise the extended epistemic responsibility in terms of extended empathic knowledge. (shrink)

We examine a prominent naturalistic line on the method of cases, exemplified by Timothy Williamson and Edouard Machery: MoC is given a fallibilist and non-exceptionalist treatment, accommodating moderate modal skepticism. But Gettier cases are in dispute: Williamson takes them to induce substantive philosophical knowledge; Machery claims that the ambitious use of MoC should be abandoned entirely. We defend an intermediate position. We offer an internal critique of Macherian pessimism about Gettier cases. Most crucially, we argue that Gettier cases needn’t exhibit (...) ‘disturbing characteristics’ that Machery posits to explain why philosophical cases induce dubious judgments. It follows, we show, that Machery’s central argument for the effective abandonment of MoC is undermined. Nevertheless, we engineer a restricted variant of the argument—in harmony with Williamsonian ideology–that survives our critique, potentially limiting philosophy’s scope for establishing especially ambitious modal theses, despite traditional MoC’s utility being partially preserved.

Brain–computer interfacing (BCI) aims at directly capturing brain activity in order to enable a user to drive an application such as a wheelchair without using peripheral neural or motor systems. Low signal to noise ratio’s, low processing speed, and huge intra- and inter-subject variability currently call for the addition of intelligence to the applications, in order to compensate for errors in the production and/or the decoding of brain signals. However, the combination of minds and machines through BCI’s and intelligent devices (...) (IDs) can affect a user’s sense of agency. Particularly confusing cases can arise when the behavioral control switches implicitly from user to ID. I will suggest that in such situations users may be insecure about the extent to which the resulting behavior, whether successful or unsuccessful, is genuinely their own. Hence, while performing an action, a user of a BCI–ID may be uncertain about being the agent of the act. Several cases will be examined and some implications for (legal) responsibility (e.g. establishing the presence of a ‘guilty mind’) are discussed. (shrink)

This article begins with a treatment of Friedrich Nietzsche’s early essay “On Truth and Lie in the Extra-Moral Sense.” The essay is often read, in the deconstructive tradition, as a showcase example of the impossibility of making a literal philosophical claim: is Nietzsche’s claim that all truth is merely metaphorical itself a true statement, or merely a metaphorical one? The present article claims that this supposed paradox relies on the groundless assumption that all philosophy must ultimately be grounded in some (...) unshakeable literal truth. From here, we turn to Edmund Gettier’s famous critique of the widespread notion of knowledge as “justified true belief.” Expanding on Gettier’s point, it is argued that there can only be “justified untrue belief” or “unjustified true belief,” never a belief that is both justified and true at once.

Research on folk epistemology usually takes place within one of two different paradigms. The first is centered on epistemic theories or, in other words, the way people think about knowledge. The second is centered on epistemic intuitions, that is, the way people intuitively distinguish knowledge from belief. In this paper, we argue that insufficient attention has been paid to the connection between the two paradigms, as well as to the mechanisms that underlie the use of both epistemic intuitions and theories. (...) We contend that research on folk epistemology must examine the use of both intuitions and theories in the pragmatic context of the game of giving and asking for reasons and, more generally, understand how these practices take place within the broader context of normative social cognition.

Knowledge intellectualism is the view that knowledge-how requires propositional knowledge. Knowledge intellectualism has a Gettier problem, or so many of its critics allege. The essence of this problem is that knowledge-how is compatible with epistemic luck in a way that ordinary propositional knowledge is not. Hence, knowledge-how can allegedly be had in the absence of knowledge-that, a fact inconsistent with knowledge intellectualism. This paper develops two responses to this challenge to knowledge intellectualism. First, it is not clear that propositional knowledge (...) is incompatible with the forms of epistemic luck with which knowledge-how is allegedly compatible. Second, existing cases intended to serve as counterexamples to knowledge intellectualism are flawed, and revised versions of these cases no longer elicit the judgments necessary to challenge knowledge intellectualism.

This article argues, against contemporary experimentalist criticism, that conceptual analysis has epistemic value, with a structure that encourages the development of interesting hypotheses which are of the right form to be valuable in diverse areas of philosophy. The article shows, by analysis of the Gettier programme, that conceptual analysis shares the proofs and refutations form Lakatos identified in mathematics. Upon discovery of a counterexample, this structure aids the search for a replacement hypothesis. The search is guided by heuristics. The heuristics (...) of conceptual analysis are similar to those in other interesting areas of scholarship, and so hypotheses generated by it are of the right form to be applicable to diverse areas. The article shows that the explanationist criterion in epistemology was developed and applied in this way. The epistemic value of conceptual analysis is oblique because it contributes not towards the main purpose of conceptual analysis but towards the reliable development of epistemically valuable hypotheses in philosophy and scholarship.

Critics of virtue reliabilism allege that the view cannot account for testimonial knowledge, as the acquisition of such knowledge is creditable to the testifier, not the recipient's cognitive abilities. I defend virtue reliabilism by attending to empirical work concerning human abilities to detect sincerity, certainty, and seriousness through bodily cues and properties of utterances. Then, I consider forms of testimony involving books, newspapers, and online social networks. I argue that, while discriminatory abilities directed at bodily cues and properties of utterances (...) are impotent in the face of such testimony, alternative abilities facilitate the acquisition of knowledge from these sources.

Drawing on new empirical data, a group of experimental philosophers have argued that one of the most popular and influential forms of skepticism is much less interesting and much less worrisome than philosophers have thought. Contrary to this claim, I argue that this brand of skepticism remains as threatening as ever. My argument also reveals an important limitation of experimental philosophy and sheds light on the way professional philosophers should go about the business of doing philosophy.

The philosophical interest in the nature, value, and varieties of human understanding has swelled in recent years. This article will provide an overview of new research in the epistemology of understanding, with a particular focus on the following questions: What is understanding and why should we care about it? Is understanding reducible to knowledge? Does it require truth, belief, or justification? Can there be lucky understanding? Does it require ‘grasping’ or some kind of ‘know-how’? This cluster of questions has largely (...) set the research agenda for the study of understanding in epistemology. This article will conclude by discussing some varieties of understanding and highlight directions for future research. (shrink)

Knowing is something that we do not have much of a theory about., p. 365.)Interest has recently been shown in causal theories of perception, memory, inference, reference, truth, justification and belief, as well as in a more general “causal theory of knowledge” which would embrace and connect all of these concepts within a broad epistemological framework. The burden of this paper is that prospects are poor for an interesting and general enough causal theory of knowledge. A threat to generality arises (...) from the causal theory's difficulties with knowledge of general truths. A threat to interest arises when attempts to accommodate general truths lead to a weakening of the notion of “causal connection” appealed to, making dubious the explanatory force of such an appeal.

While the pursuitworthiness of philosophical ideas has changed over time, philosophical practice and methodology have not kept pace. The worthiness of a philosophical pursuit includes not only the ideas and objectives one pursues but also the methods with which one pursues them. In this paper, we articulate how empirical approaches benefit philosophy of science, particularly advocating for the use of qualitative methods for understanding the social and normative aspects of scientific inquiry. After situating qualitative methods within empirical philosophy of science, (...) we discuss how to adapt these traditionally sociological methods to empirically inform philosophical questions. Our aim is to normalize and legitimize qualitative methods for philosophical purposes and discuss how they can elucidate descriptive and normative components of scientific practice in a more generalizable non-idealized manner. We contend that qualitative methods are particularly well suited to philosophical interest in the social norms of science, their achievability, and their mutability. Furthermore, unlike more historical case studies in philosophy, qualitative methods enable more confidence in generalizability, albeit limited, from a concrete sample to a larger class. We conclude by addressing anxieties about the distinctness of empirical philosophy of science from social epistemology and from sociology of science. (shrink)

This paper defends a challenge, inspired by arguments drawn from contemporary ordinary language philosophy and grounded in experimental data, to certain forms of standard philosophical practice. The challenge is inspired by contemporary philosophers who describe themselves as practicing “ordinary language philosophy”. Contemporary ordinary language philosophy can be divided into constructive and critical approaches. The critical approach to contemporary ordinary language philosophy has been forcefully developed by Avner Baz, who attempts to show that a substantial chunk of contemporary philosophy is fundamentally (...) misguided. I describe Baz’s project and argue that while there is reason to be skeptical of its radical conclusion, it conveys an important truth about discontinuities between ordinary uses of philosophically significant expressions (“know”, e.g.) and their use in philosophical thought experiments. I discuss some evidence from experimental psychology and behavioral economics indicating that there is a risk of overlooking important aspects of meaning or misinterpreting experimental results by focusing only on abstract experimental scenarios, rather than employing more diverse and more ecologically valid experimental designs. I conclude by presenting a revised version of the critical argument from ordinary language. (shrink)

It is almost universally presumed that knowledge is factive: in order to know that p it must be the case that p is true. This idea is often justified by appealing to knowledge ascriptions and related linguistic phenomena; i.e., an utterance of the form ‘S knows that p, but not-p’ sounds contradictory. In a recent article, Allan Hazlett argues that our ordinary concept of knowledge is not factive. From this it seems to follow that epistemologists cannot appeal to ordinary language (...) to justify the truth condition of knowledge. More significantly, Hazlett claims that epistemologists theorizing about knowledge should not concern themselves with the ordinary concept of knowledge as revealed by knowledge ascriptions and related linguistic phenomena. My paper has two goals: first, to defend the orthodox view that the ordinary concept of knowledge is factive; second, to undermine Hazlett’s claim that epistemologists should not theorize about knowledge on the basis of how ‘knows’ is used in everyday speech.

This paper defends the epistemological doctrine of fallibilism from recent objections. In “The Myth of Knowledge” Laurence BonJour argues that we should reject fallibilism for two main reasons: first, there is no adequate way to specify what level of justification is required for fallible knowledge; second, we cannot explain why any level of justification that is less than fully conclusive should have the significance that makes knowledge valuable. I will reply to these challenges in a way that allows me to (...) make progress on a number of important issues in contemporary epistemology: epistemic value, the functional roles of knowledge attributions, experimental epistemology, skepticism, the Gettier problem, and the lottery paradox. My argument is motivated by appealing to various insights derived from the method of ‘practical explication’, particularly the idea that a central purpose of the concept of knowledge is to flag reliable informants. My conclusion is that various practical and theoretical considerations derived from the method of practical explication support the fallibilist conception of knowledge. (shrink)

Despite their common core concept, philosophy and knowledge management (KM) have not yet found a mutually inspiring base. Theories of KM cite philosophical works, more or less adequately, while philosophy tends to ignore theories of KM.

Starting with the development of a concept of knowledge that is the base of the common understanding, the critical review of (...) knowledge management theories reveals conceptual flaws and the need for useful criteria to support successful KM.

The question of whether knowledge is definable in terms of belief, which has played an important role in epistemology for the last 50 years, is studied here in the framework of epistemic and doxastic logics. Three notions of definability are considered: explicit definability, implicit definability, and reducibility, where explicit definability is equivalent to the combination of implicit definability and reducibility. It is shown that if knowledge satisfies any set of axioms contained in S5, then it cannot be explicitly defined in (...) terms of belief. S5 knowledge can be implicitly defined by belief, but not reduced to it. On the other hand, S4.4 knowledge and weaker notions of knowledge cannot be implicitly defined by belief, but can be reduced to it by defining knowledge as true belief. It is also shown that S5 knowledge cannot be reduced to belief and justification, provided that there are no axioms that involve both belief and justification. (shrink)
