Defining Knowledge, Misc

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.

This paper is an extended prolepsis in favor of epistemic situationism, the thesis that epistemic virtues are not sufficiently widely distributed for a virtue-theoretic constraint on knowledge to apply without leading to skepticism. It deals with four objections to epistemic situation: 1) that virtuous dispositions are not required for knowledge, 2) that the Big Five or Big Six personality model proves that intellectual virtues are a reasonable ideal, 3) that the cognitive-affective personality system framework proves that intellectual virtues are a (...) reasonable ideal, and 4) that weakening the reliability requirement through epistemic dependence or abilism means that common inferential strategies really are virtues. The paper concludes with reflections on the replication crisis in psychological science. (shrink)

The traditional tripartite and tetrapartite analyses describe the conceptual components of propositional knowledge from a universal epistemic point of view. According to the classical analysis, since truth is a necessary condition of knowledge, it does not make sense to talk about “false knowledge” or “knowing wrongly.” There are nonetheless some natural languages in which speakers ordinarily make statements about a person’s knowing a given subject matter wrongly. In this paper, we first provide a brief analysis of “knowing wrongly” in Turkish. (...) Then, taking Allan Hazlett’s recent account of the gap between traditional analyses of knowledge and actual epistemic practices of real cognitive agents as a point of departure, we spell out a non-universalist and non-extensionalist perspective on the value of “knowing wrongly.”.

Christoph Jäger (2004) argues that Dretske's information theory of knowledge raises a serious problem for his denial of closure of knowledge under known entailment: Information is closed under known entailment (even under entailment simpliciter); given that Dretske explains the concept of knowledge in terms of "information", it is hard to stick with his denial of closure for knowledge. Thus, one of the two basic claims of Dretske would have to go. Since giving up the denial of closure would commit Dretske (...) to skepticism, it would most probably be better to rather give up the information-theoretic account of knowledge. But that means that one of the best externalist views of knowledge has to be given up. I argue here that Jäger is mistaken and that there is no problem for Dretske. There is a rather easy way out of Jäger’s problem. (shrink)

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)

A central topic in experimental epistemology has been the ways that non-epistemic evaluations of an agent’s actions can affect whether the agent is taken to have certain kinds of knowledge. Several scholars have found that the positive or negative valence of an action can influence attributions of knowledge to the agent. These evaluative effects on knowledge attributions are commonly seen as performance errors, failing to reflect individuals’ genuine conceptual competence with knows. In the present article, I report the results of (...) a series of studies designed to test the leading version of this view, which appeals to the allegedly distorting influence of individuals’ motivation to blame. I argue that the data pose significant challenges to such a view. (shrink)

A number of researchers have begun to demonstrate that the widely discussed ?Knobe effect? (wherein participants are more likely to think that actions with bad side-effects are brought about intentionally than actions with good or neutral side-effects) can be found in theory of mind judgments that do not involve the concept of intentional action. In this article we report experimental results that show that attributions of knowledge can be influenced by the kinds of (non-epistemic) concerns that drive the Knobe effect. (...) Our findings suggest there is good reason to think that the epistemic version of the Knobe effect is a theoretically significant and robust effect, and that the goodness or badness of side-effects can often have greater influence on participant knowledge attributions than explicit information about objective probabilities. Thus, our work sheds light on important ways in which participant assessments of actions can affect the epistemic assessments participants make of agents? beliefs. (shrink)

An overview of philosophical work on the distinction between knowledge how and knowledge that, focusing on what it means to say that they are 'distinct', and on what is at stake in the debate between intellectualists and anti-intellectualists about knowledge how.

Roderick Chisholm argues that in giving an account of knowledge, we must either begin with an account of what knowledge is, and proceed on that basis to identify the particular things that we know, or else start with instances of knowledge, and proceed on that basis to formulate a definition of knowledge. Either approach begs the question against the other. This is the epistemic wheel. This article responds to Chisholm's challenge. It begins with cases of knowledge attribution and builds its (...) account from there, identifying those features that we take to be present in the cases where we have attributed knowledge and those features that seem important when we want to withhold an attribution of knowledge. The proposal does not beg the question against either particularists or methodists; it takes the best features of each view, without beginning with either, and thereby removes us from the wheel.

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)

Stephen Hetherington has defended the tripartite analysis of knowledge (Hetherington in Philos Q 48:453–469, 1998; J Philos 96:565–587, 1999; J Philos Res 26:307–324, 2001a; Good knowledge, bad knowledge, Oxford University Press, Oxford, 2001b). His defence has recently come under attack (Madison in Australas J Philos 89(1):47–58, 2011; Turri in Synthese 183(3):247–259, 2012). I critically evaluate those attacks as well as Hetherington’s newest formulation of his defence (Hetherington in Philosophia 40(3):539–547, 2012b; How to know: A practicalist conception of knowledge, Wiley, Oxford, (...) 2011a; Ratio 24:176–191, 2011b; Synthese 188:217–230, 2012a). I argue that his newest formulation is vulnerable to a modified version of Madison’s and Turri’s objection. However, I argue that Hetherington’s considerations lend support to a different, though also radical, thesis which can meet the objection. This thesis is what I call the Divorce thesis: the theory of epistemic justification is importantly independent of the theory of knowledge. (shrink)

Anti-luck epistemologists tell us that knowledge is incompatible with epistemic luck and that epistemic luck is just a special case of luck in general. Much work has been done on the intricacies of the first claim. In this paper, I scrutinize the second claim. I argue that it does not survive scrutiny. I then offer an analysis of luck that explains the relevant data and avoids the problems from which the current views of luck suffer. However, this analysis of luck (...) is of no help to the anti-luck epistemologist for it uses knowledge to explain luck, making this account of knowledge circular. The main lesson is that the only viable analysis of luck is not suited for the anti-luck epistemologist's coveted noncircular analysis of knowledge. (shrink)

This is a reply to John N. Williams’ paper “Not Knowing You Know: A New Objection to the Defeasibility Theory of Knowledge'” (2015). That paper argues that Peter Klein’s defeasibility theory of knowledge excludes the possibility of one knowing that one has (first-order) a posteriori knowledge. Klein himself answered a version of this objection in his (1971). Williams’ paper adds a new twist to the 1971 objection. I argue that Williams’ objection misses its target because of this new twist.

This is an edited collection of twenty-three (23) new papers on the Gettier Problem and the issues connected with it. The set of authors includes many of the major figures in contemporary epistemology who have developed some of the well-known responses to the Problem, and the list contains some younger epistemologists who bring new perspectives to the issues raised in the literature. Together, they cover the state of the art scholarship on virtually every epistemological and methodological aspect of the Gettier (...) Problem. (shrink)

I defend the view that propositional knowledge can be defined as follows: A knows that p if and only if A believes that p because p. Spelling out the meaning of 'because' in this formula results in a causal-explanatory view of knowledge.

Duncan Pritchard has, in the years following his (2005) defence of a safety-based account of knowledge in Epistemic Luck, abjured his (2005) view that knowledge can be analysed exclusively in terms of a modal safety condition. He has since (Pritchard in Synthese 158:277–297, 2007; J Philosophic Res 34:33–45, 2009a, 2010) opted for an account according to which two distinct conditions function with equal importance and weight within an analysis of knowledge: an anti-luck condition (safety) and an ability condition-the latter being (...) a condition aimed at preserving what Pritchard now takes to be a fundamental insight about knowledge: that it arises from cognitive ability (Greco 2010; Sosa 2007, 2009). Pritchard calls his new view anti-luck virtue epistemology (ALVE). A key premise in Pritchard’s argument for ALVE is what I call the independence thesis; the thesis that satisfying neither the anti-luck condition nor the ability condition entails that the other is satisfied. Pritchard’s argument for the independence thesis relies crucially upon the case he makes for thinking that cognitive achievements are compatible with knowledge-undermining environmental luck—that is, the sort of luck widely thought to undermine knowledge in standard barn facade cases. In the first part of this paper, I outline the key steps in Pritchard’s argument for anti-luck virtue epistemology and highlight how it is that the compatibility of cognitive achievement and knowledge- undermining environmental luck is indispensible to the argument’s success. The second part of this paper aims to show that this compatibility premise crucial to Pritchard’s argument is incorrect. (shrink)

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)

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.

Our curiosity has us interested in finding out the truth. Knowing the fact of the matter fulfills the interest. This fulfillment is something satisfying about knowledge. Additionally, knowledge is a good way for a person to relate to a proposition. Knowing is good because of what knowledge is. In other words, knowledge is intrinsically good. The credibility of these assessments calls for some explanation. A traditional view is that knowledge is justified true belief with no Gettier accidents. This conception is (...) particularly helpful in accounting for the assessments of knowledge. Features of the relation of a mind to a known proposition that are articulated in the traditional view make the relation satisfying and attractive. What is explicit in the traditional view renders these assets of knowledge readily understandable. The view explains the assets better than do alternative conceptions of knowledge. (shrink)

This accessible essay treats knowledge and belief in a usable and applicable way. Many of its basic ideas have been developed recently in Corcoran-Hamid 2014: Investigating knowledge and opinion. The Road to Universal Logic. Vol. I. Arthur Buchsbaum and Arnold Koslow, Editors. Springer. Pp. 95-126. http://www.springer.com/birkhauser/mathematics/book/978-3-319-10192-7 .

Dans cet ouvrage, l’auteur discute d’abord un un ensemble d’idées de sens commun qui permettent de mieux cerner la notion de connaissance : nous savons beaucoup de choses, ce que nous savons ne vient pas toujours des sciences, tout ce que nous savons est vrai, la connaissance est le but de l’enquête, on ne doit croire et affirmer que ce que l’on sait, on ne doit agir que sur la base de ce que l’on sait, la connaissance a de la (...) valeur. Il donne ensuite une vue d’ensemble des débats contemporains en philosophie de la connaissance en les resituant dans une perspective historique. (shrink)

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.

Quassim Cassam offers a conception of ways of knowing which he argues is preferable to rival accounts such as the account we find in Williamson. The correct way to think about ways of knowing matters for philosophers, such as Cassam and Williamson, who want to understand knowledge itself in terms of ways of knowing. So is Cassam right that his conception of ways of knowing is preferable to Williamson's? The discussion to follow is irenic in spirit: I will argue that (...) in fact Cassam and Williamson don't offer competing accounts of the same phenomenon, but consistent accounts of subtly different phenomena. It is then open that ways of knowing in both senses are relevant to elucidating knowledge itself. (shrink)

In this paper, we examine some issues debated in mainstream epistemology for which the social features of knowledge are relevant, such as the epistemic relevance of social contexts, the nature of practical knowledge, and the epistemic role of testimony. In the first part of the paper, we show how feminist epistemologies have usefully stressed the social character of knowledge in many central areas of debate within mainstream epistemology. We call these the virtues of feminist epistemology: the denial of the neutrality (...) and autonomy of the epistemic subject, the focus on practical knowledge, and the ensuing attention to the social dimensions of the epistemic process. Our conclusion on the social dimensions of knowledge is the thesis that the epistemic subject can know only in connection with others. In the second part of the paper, we address the issue of the plausibility of feminist epistemologies by discussing three main criticisms which have been raised against them. We conclude that, even if these criticisms are valid, the legacy of feminist epistemologies remains because the social features of knowledge are plausibly significant not only within but also without the perspectives of feminist epistemologies.

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.

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)

In the present paper we propose a system of propositional logic for reasoning about justification, truthmaking, and the connection between justifiers and truthmakers. The logic of justification and truthmaking is developed according to the fundamental ideas introduced by Artemov. Justifiers and truthmakers are treated in a similar way, exploiting the intuition that justifiers provide epistemic grounds for propositions to be considered true, while truthmakers provide ontological grounds for propositions to be true. This system of logic is then applied both for (...) interpreting the notorious definition of knowledge as justified true belief and for advancing a new solution to Gettier counterexamples to this standard definition.

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)

In When is True Belief Knowledge? (2012) Richard Foley proposes an original and strikingly simple theory of knowledge: a subject S knows some proposition p if and only if S truly believes that p and does not lack any important information. If this view is correct, Foley allegedly solves a wide variety of epistemological problems, such as the Gettier problem, the lottery paradox, the so-called ‘value problem’, and the problem of skepticism. However, a central component of his view is that (...) whether a true belief counts as knowledge depends on the importance of the information that one has or lacks. My paper raises doubts about whether there is a non-circular way to distinguish important information from unimportant information. I argue that there is no way to distinguish important information from unimportant information without ultimately making reference to knowledge; thus, Foley’s new theory of knowledge does not achieve its goals. (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. (shrink)

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 (BIVs), 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)

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 “The Myth of Factive Verbs” (Hazlett 2010), I had four closely related goals. The first (pp. 497-99, p. 522) was to criticize appeals to ordinary language in epistemology. The second (p. 499) was to criticize the argument that truth is a necessary condition on knowledge because “knows” is factive. The third (pp. 507-19) – which was the intended means of achieving the first two – was to defend a semantics for “knows” on which <S knows p> can be true (...) even if p isn’t true. The fourth (Ibid.) – which seemed necessary for the success of the third – was to defend a pragmatic account of the fact that utterances of <S knows p> typically imply p, on which the implication in those cases is down to conversational implicature. In this paper I’ll go after these goals again, with an emphasis on the second. Our topic will be whether the factivity of “knows” (whatever this amounts to) supports the truth condition on knowledge. A new goal will be to defend my argument against some criticisms from John Turri (2011) and Savas Tsohatzidis (forthcoming). We’ll first look at the truth condition (§1) and factive presupposition (§§2 – 3), before turning to replies to Turri and Tsohatzidis (§§4 – 7). (shrink)

Richard Feldman and William Lycan have defended a view according to which a necessary condition for a doxastic agent to have knowledge is that the agent’s belief is not essentially based on any false assumptions. I call this the no-essential-false-assumption account, or NEFA. Peter Klein considers examples of what he calls “useful false beliefs” and alters his own account of knowledge in a way which can be seen as a refinement of NEFA. This paper shows that NEFA, even given Klein’s (...) refinement, is subject to counterexample: a doxastic agent may possess knowledge despite having an essential false assumption. Advocates of NEFA could simply reject the intuition that the example is a case of knowledge. However, if the example is interpreted as not being a case of knowledge, then it can be used as a potential counterexample against both safety and sensitivity views of knowledge. I also provide a further case which, I claim, is problematic for all of the accounts just mentioned. I then propose, briefly, an alternative account of knowledge which handles all these cases appropriately. (shrink)

The article talks about the social consequences of the so called Standard Analysis of Knowledge. Gettier cases demonstrate that human beings would need superhuman powers in order to fullfill the truth condition of the Standard Analysis of Knowledge. When Gettier cases are told, the storyteller usually omits to report who noticed what was the truth in this case and how he or she informed the protagonist of the Gettier case about it. This is done that way in order to hide (...) the fact that only the eye of God could have established the truth in a Gettier case because it was hidden from the protagonist by some specific circumstance. When people understand their own knowledge according to the Standard Analysis of Knowledge, that means that they are very sure of themselves and their capabilities. They orientate themselves by the rigorous standard of truth instead of some more moderate claim like, e.g., the helpfulness of a certain belief in the fight of everyday life. Such persons tend to act some teachers who judge their pupils only by their mistake (failure to achieve the truth) instead of by their (humble but admirable) achievements. When such persons meet weaker epistemic subjects, like pupils, students, laypeople, or chronically ill persons, their assertiveness can have a negative effect on their self-confidence. By undermining their self-confidence they will make these people unsure and, hence, ignorant even of the things they normally do know. Would the Standard Analysis of Knowledge therefore be the appropiate theoretical concept for as schooling of chronically ill persons - like in the British Expert Patients Programm - on the subject of their illness? Such a schooling is highly desirable from the ethical (increase of autonomy of chronically ill persons) as well as from the social standpoint (decrease of healthcare costs). However, in order to make weak people stronger as epistemic subjects, truth, as an absolute goal, is unrewarding. Knowledge about their own health condition needs to have the function of helping them to do things better than up to now - better, but not perfect as the truth condition (which is perfect) of the Standard Analysis of Knowledge requires. In sum, in the social context of stronger and weaker epistemic subjects the truth condition of knowledge turns out to be inhuman and should be substituted by a set of other conditions that focus on what can help to increase the ability to act of the (weaker) expistemic subject.

Response to Sven Bernecker's "On the Metaphysics of Knowledge" in the same volume.

Infallibilism is the view that a belief cannot be at once warranted and false. In this essay we assess three nonpartisan arguments for infallibilism, arguments that do not depend on a prior commitment to some substantive theory of warrant. Three premises, one from each argument, are most significant: (1) if a belief can be at once warranted and false, then the Gettier Problem cannot be solved; (2) if a belief can be at once warranted and false, then its warrant can (...) be transferred to an accidentally true belief; (3) if a belief can be at once warranted and false, then it can be warranted and accidentally true. We argue that each of these is either false or no more plausible than its denial. Along the way, we offer a solution to the Gettier Problem that is compatible with fallibilism. (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)

Robert Almeder has argued1 that three “fourth conditions” for nondefectiveness of knowledge justification claims, proposed in the recent literature,2 are essentially similar, require modification in order to eliminate the possibility of an unknowable defeater, and, so modified, render attainment of non-basic factual knowledge impossible. Although I believe there are objections to be raised against his exposition and reduction of the three proposed fourth conditions, I wish only to raise some doubts about the supposed necessity of the modifications and then to (...) argue against his claim that, so modified, the result is too stringent.

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. -/- .
