Defining Knowledge, Misc

In his book Knowledge and Practical Interests Jason Stanley offers an argument for the conclusion that it is quite unlikely that an ambiguity theory of ‘knows’ can be “linguistically grounded”. His argument rests on two important assumptions: that linguistic grounding of ambiguity requires evidence of the purported different senses of a word being represented by different words in other languages and that such evidence is lacking in the case of ‘knows’. In this paper, I challenge the conclusion that there isn’t (...) a linguistic grounding for an ambiguity theory of ‘knows’ by making cases against both of Stanley’s major assumptions. I will do this by making a case for a prime facie linguistic grounding for a polysemy theory of ‘knows’ without appealing to word use in other languages. Given that a polysemy theory of ‘knows’ is a type of ambiguity theory of ‘knows’, if I succeed in linguistically grounding a polysemy theory of ‘knows’, then I have shown that at least one type of ambiguity theory of ‘knows’ can be linguistically grounded.

A review of "Achieving Knowledge" by John Greco.

A standard view in philosophy is that knowledge entails justification. Yet recent research suggests otherwise. We argue that this admirable and striking research suffers from an important limitation: participants were asked about knowledge but not justification. Thus it is possible that people attributed knowledge partly because they thought the belief was justified. Perhaps though, if given the opportunity, people would deny justification while still attributing knowledge. It is also possible that earlier findings were due to perspective taking. This paper reports (...) further research that directly addresses these questions. Our findings support the hypothesis that knowledge entails justification on the ordinary view. (shrink)

Virtue epistemologists define knowledge as true belief produced by intellectual virtue. In this paper, I review how this definition fails in three important ways. First, it fails as an account of the ordinary knowledge concept, because neither belief nor reliability is essential to knowledge ordinarily understood. Second, it fails as an account of the knowledge relation itself, insofar as that relation is operationalized in the scientific study of cognition. Third, it serves no prescriptive purpose identified up till now. An alternative (...) theory, abilism, provides a superior account of knowledge as it is ordinarily and scientifically understood. According to abilism, knowledge is an accurate representation produced by cognitive ability. (shrink)

“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.

Approximation involves representing things in ways that might be close to the truth but are nevertheless false. Given the widespread reliance on approximations in science and everyday life, here we ask whether it is conceptually possible for false approximations to qualify as knowledge. According to the factivity account, it is impossible to know false approximations, because knowledge requires truth. According to the representational adequacy account, it is possible to know false approximations, if they are close enough to the truth for (...) present purposes. In this paper, we adopt an experimental methodology to begin testing these two theories. When an agent provides a false and practically inadequate answer, both theories predict that people will deny knowledge. But the theories disagree about an agent who provides a false but practically adequate answer: the factivity hypothesis again predicts knowledge denial, whereas the representational adequacy hypothesis predicts knowledge attribution. Across two experiments, our principal finding was that people tended to attribute knowledge for false but practically adequate answers, which supports the representational adequacy account. We propose an interpretation of existing findings that preserves a conceptual link between knowledge and truth. According to this proposal, truth is not necessary for knowledge, but it is a feature of prototypical knowledge. (shrink)

Rachael Briggs and Daniel Nolan have recently proposed an improved version of Nozick’s tracking account of knowledge. I show that, despite its virtues, the new proposal suffers from three serious problems.

It is widely accepted in epistemology that knowledge is factive, meaning that only truths can be known. We argue that this theory creates a skeptical challenge: because many of our beliefs are only approximately true, and therefore false, they do not count as knowledge. We consider several responses to this challenge and propose a new one. We propose easing the truth requirement on knowledge to allow approximately true, practically adequate representations to count as knowledge. In addition to addressing the skeptical (...) challenge, this view also coheres with several previous theoretical proposals in epistemology. (shrink)

Modalists think that knowledge requires forming your belief in a “modally stable” way: using a method that wouldn't easily go wrong (i.e. safety), or using a method that wouldn't have given you this belief had it been false (i.e. sensitivity). Recent Modalist projects from Justin Clarke-Doane and Dan Baras defend a principle they call “Modal Security,” roughly: if evidence undermines your belief, then it must give you a reason to doubt the safety or sensitivity of your belief. Another recent Modalist (...) project from Carlotta Pavese and Bob Beddor defends “Modal Virtue Epistemology”: knowledge is a belief that is maximally modally robust across “normal” worlds. We'll offer new objections to these recent Modalist projects. We will then argue for a rival view, Explanationism: knowing something is believing it because it's true. We will show how Explanationism offers a better account of undermining defeaters than Modalism, and a better account of knowledge. (shrink)

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.

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)

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)

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)

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.

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 words; 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)

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)

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)

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.

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.

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.

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.

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.

Anti-intellectualists about knowledge-how insist that, when an agent S knows how to φ, it is in virtue of some ability, rather than in virtue of any propositional attitudes, S has. Recently, a popular strategy for attacking the anti-intellectualist position proceeds by appealing to cases where an agent is claimed to possess a reliable ability to φ while nonetheless intuitively lacking knowledge-how to φ. John Bengson & Marc Moffett (2009; 2011a; 2011b) and Carlotta Pavese (2015a; 2015b) have embraced precisely this strategy (...) and have thus claimed, for different reasons, that anti-intellectualism is defective on the grounds that possessing the ability to φ is not sufficient for knowing how to φ. We investigate this strategy of argument-by-counterexample to the anti- intellectualist’s sufficiency thesis and show that, at the end of the day, anti-intellectualism remains unscathed. (shrink)

The traditional conception of knowledge is justified, true belief. If one looks at a modern textbook on epistemology, the great bulk of questions with which it deals are to do with personal knowledge, as embodied in beliefs and the proper experiences that someone ought to have had in order to have the right (or justification) to know. I intend to argue that due to the explosive growth of knowledge whose domain is “outside the head”, this conception has outlived its relevance. (...) -/- On the other hand, Karl Popper’s (1934) Falsificationism, with its emphasis on the objective character of knowledge, is not only a sounder, but also a more appropriate theory of knowledge for understanding the nature and growth of civilization. Later, Popper (1945) generalized this approach to obtain critical rationalism, in which all claims to knowledge, whether scientific or otherwise, are understood as objective solutions to objective problems and can be evaluated by other non-observational - types of criticism. I will first argue that Popper’s methodology is quite suited to the view that knowledge is an objective autonomous product and then adduce his theory of world 3, an ontology that neatly wraps up various considerations. World 3 is the domain of abstract products of the human mind that now have a life of their own, outside of human heads: theories, arguments, problems, plans, etc. I then adduce some other arguments for the autonomous quality of knowledge.

Belief-state ascription — determining what someone “knew,” “believed,” was “aware of,” etc. — is central to many areas of law. In criminal law, the distinction between knowledge and recklessness, and the use of broad jury instructions concerning other belief states, presupposes a common and stable understanding of what those belief-state terms mean. But a wealth of empirical work at the intersection of philosophy and psychology — falling under the banner of “Experimental Epistemology” — reveals how laypeople’s understandings of mens rea (...) concepts differ systematically from what scholars, courts, and perhaps legislators, have assumed. -/- As implemented, mens rea concepts are much more context-dependent and normatively evaluative than the conventional wisdom suggests, even assuming that jurors are following jury instructions to the letter. As a result, there is less difference between knowledge and recklessness than is typically assumed; jurors consistently “over”-ascribe knowledge to criminal defendants; and concepts like “belief,” “awareness,” and “conscious disregard” mean different things in different contexts, resulting in mens rea findings systematically responsive to aspects of the case traditionally considered irrelevant to the meaning of those terms. -/- This Article provides the first systematic account of the factors driving jurors’ ascriptions of the specific belief states criminal law invokes. After surveying mens rea jury instructions, introducing the Experimental Epistemology literature to the legal literature on mens rea, and examining the implications of that literature for criminal law, this Article considers ways to begin bridging the surprisingly large gap between mens rea theory and practice.

I present an argument for a sophisticated version of sceptical invariantism that has so far gone unnoticed: Bifurcated Sceptical Invariantism (BSI). I argue that it can, on the one hand, (dis)solve the Gettier problem, address the dogmatism paradox and, on the other hand, show some due respect to the Moorean methodological incentive of ‘saving epistemic appearances’. A fortiori, BSI promises to reap some other important explanatory fruit that I go on to adduce (e.g. account for concessive knowledge attributions). BSI can (...) achieve this much because it distinguishes between two distinct but closely interrelated (sub)concepts of (propositional) knowledge, fallible-but-safe knowledge and infallible-and-sensitive knowledge, and explains how the pragmatics and the semantics of knowledge discourse operate at the interface of these two (sub)concepts of knowledge. I conclude that BSI is a novel theory of knowledge discourse that merits serious investigation. (shrink)

On Relation between the Individual Character of Propositional Knowledge and Its Value -/- The paper presents two aspects of human propositional knowledge, objective and subjective. The former is based on the truth condition, and the latter on the belief condition. Then several problems of the value of knowledge are briefly presented. The last part contains two arguments for the sine qua non belief condition of knowledge, one of which concerns the problem of epistemic luck assumed in virtue.

I begin by criticizing reductionist knowledge-first epistemology according to which knowledge can be used to reductively analyze other epistemic phenomena. My central concern is that proponents of such an approach commit a similar mistake to the one that they charge their opponents with. This is the mistake of seeking to reductively analyze basic epistemic phenomena in terms of other allegedly more fundamental phenomena. I then turn to non-reductionist brands of knowledge-first epistemology. Specifically, I consider the knowledge norms of assertion and (...) contrast them with an alternative that I have developed elsewhere (Gerken 2011, 2012a, 2013b, 2014, 2015a, 2015c, MS). On the basis of the critical discussion, I question whether a knowledge-first program that is both plausible and distinctive has been identified. On a more positive note, I sketch the contours of an alternative that I label ‘equilibristic epistemology.’ According to this approach, there isn’t a single epistemic phenomenon or concept that is “first.” Rather, there are a number of basic epistemic phenomena that are not reductively analyzable although they may be co-elucidated in a non-reductive manner. This approach preserves some grains of truth in knowledge-first epistemology. For example, it preserves the idea that knowledge can be taken to be explanatorily basic and unanalyzable. However, since no single epistemic phenomenon is first, knowledge is not first. (shrink)

This paper argues for an overlooked dimension in the metaphysical microstructure of knowledge. The connection between knowledge and truth is even deeper than generally acknowledged. Knowledge, I argue, supervenes not only on a specific (namely modal) relation between the proposition p’s truth and an agent’s belief that p, but also on specific relations between the proposition’s truthmaker and the belief’s justification-maker. S knows that p only if the states of affairs referred to by S’s reasons for believing that p are (...) identical with, causally related to, or grounded in the states of affairs that make p true. (shrink)

I present two counterexamples to the recently back-in-favour truth-tracking account of knowledge: one involving a true belief resting on a counterfactually robust delusion, one involving a true belief acquired alongside a bunch of false beliefs. These counterexamples carry over to a recent modification of the theory due to Briggs and Nolan (2012), and seem invulnerable to a recent defence of the theory against known counterexamples, by Adams and Clarke (2005).

In his “On the Metaphysics of Knowledge” (this volume), Sven Bernecker presents a novel ‘identificationist’ account of knowledge. In this paper, I will not directly address the epistemological adequacy of Bernecker’s identificationism. Rather, I want to focus on its substantial metaphysical commitments, especially on the problematic idea that our epistemic reasons identify the truthmaker of our respective belief when we know something. My conclusion will be that being a truthmaker for p is metaphysically more demanding than being an epistemic reason (...) for p. A truthmaker for p must necessitate the truth of p, while an epistemic reason for p must merely indicate the truth of p. Thus, we should not expect that epistemic reasons identify the truthmakers of our knowledge-constituting beliefs in the way Bernecker suggests. (shrink)

The point of Wittgenstein’s remarks on colour concerns, not so much colours as such, as well as our ability to see [that implies both seeing ánd thinking] and our capacity to imagine something.

This connection between Wittgenstein’s remarks on colour, on seeing aspects (...) and on certainty makes clear that these investigations of Wittgenstein direct us towards a reflective dynamics of his ideas.

Abstract In this paper I present a short outline of an Indicativity Theory of Knowledge, for the cases of Perceptual Knowledge and Knowledge by Memory. I explain the main rationale for a token-indicativity approach, and how it is fleshed out precisely in terms of chances. I elaborate on the account of the value of knowledge it provides, and what that value is. I explain why, given the rationale of conceiving Knowledge as token indicativity, separate sub-accounts in terms of chances should (...) be extracted for the different modes of Knowledge, elaborating on the common core of high token-indicativity. In the main section that outlines the account of Perceptual Knowledge, the main Indicativity condition is presented, as are the main condition of in what sense high token indicativity should yields high chance, the important Discriminability condition, and its associated Contrast Class.

Mark Schroeder has recently proposed a new analysis of knowledge. I examine that analysis and show that it fails. More specifically, I show that it faces a problem all too familiar from the post-Gettier literature, namely, that it is delivers the wrong verdict in fake barn cases.

Let ‘warrant’ denote whatever precisely it is that makes the difference between knowledge and mere true belief. A current debate in epistemology asks whether warrant entails truth, i.e., whether (Infallibilism) S’s belief that p is warranted only if p is true. The arguments for infallibilism have come under considerable and, as of yet, unanswered objections. In this paper, I will defend infallibilism. In Part I, I advance a new argument for infallibilism; the basic outline is as follows. Suppose fallibilism is (...) true. An implication of fallibilism is that the property that makes the difference between knowledge and mere belief (which I dub ‘warrant*’) is the conjunctive property being warranted and true . I show that this implication of fallibilism conflicts with an uncontroversial thesis we have learned from reflection on Gettier cases: that nonaccidental truth is a constituent of warrant*. It follows that infallibilism is true. In the second part of the paper, I present and criticize a new argument against infallibilism. The argument states that there are plausible cases where, intuitively, the only thing that is keeping a belief from counting as knowledge is the falsity of that belief. Furthermore, it is plausible that such a belief is warranted and false. So, the argument goes, infallibilism is false. I show that this argument fails. (shrink)

Russell identifies the conflict between the ego of self and the greater universe causes internal strife that can only be resolved by truly open questioning. Through this, we are enriching our lives and our minds, while becoming closer to our universal truths.

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.
