Stewart Cohen argues that several epistemological theories fall victim to the problem of easy knowledge: they allow us to know far too easily that certain sceptical hypotheses are false and that how things seem is a reliable indicator of how they are. This problem is a result of the theories' interaction with an epistemic closure principle. Cohen suggests that the theories should be modified. I argue that attempts to solve the problem should focus on closure (...) instead; a new and plausible epistemic closure principle can solve the problem of easy knowledge. My solution offers a uniform and more successful response to different versions of the problem of easy knowledge. (shrink)

The dominant response to this problem of the criterion focuses on the alleged requirement that we need to know a belief source is reliable in order for us to acquire knowledge by that source. Let us call this requirement, “The KR principle”.

The dominant response to this problem of the criterion focuses on the alleged requirement that we need to know a belief source is reliable in order for us to acquire knowledge by that source. Let us call this requirement, “The KR principle”.

The paper deals with a version of the principle that a belief source can be a knowledge source only if the subject knows that it is reliable. I argue that the principle can be saved from the main objections that motivate its widespread rejection: the claim that it leads to skepticism, the claim that it forces us to accept counterintuitive knowledge ascriptions and the claim that it is incompatible with reliabilist accounts of knowledge. I argue that naturalist (...) epistemologists should reject these claims. I introduce my treatment of the principle by considering the analogous situation posed by the closure principle. (shrink)

Consider the following epistemological principle:KR: A knowledge source K can yield knowledge for subject S only if S knows K is reliable.Traditional epistemologists face a dilemma: either reject KR and confront what Stewart Cohen calls “the Problem of Easy Knowledge” or embrace KR and deny that unreflective beings can possess knowledge. In order to avoid this dilemma, an epistemological theory must allow for knowledge on the part of unreflective beings without falling prey to (...) the problem of easy knowledge. I argue that the epistemology of the dying Wittgenstein, presented posthumously in On Certainty, avoids the dilemma. (shrink)

Many philosophers hold some verion of the doctrine of "basic knowledge". According to this doctrine, it's possible for S to know that p, even if S doesn't know the source of her knowledge that p to be reliable or trustworthy. Stewart Cohen has recently argued that this doctrine confronts the problem of easy knowledge. I defend basic knowledge against this criticism, by providing a contextualist solution to the problem of easy knowledge.

The preface paradox is a problem for everyone; you don’t need to be committed to any special epistemological theory to face the problem it raises. The problem of easy knowledge is supposed to be different in this respect. It is generally thought to arise only for those who believe there is such a thing as basic knowledge, i.e. knowledge acquired through a source that one does not know to be reliable or trustworthy. Because (...) it is thought to arise only for those who believe in basic knowledge, the problem of easy knowledge is generally regarded as a problem for, or objection to, the possibility of basic knowledge.

O problema do conhecimento fácil tem sido definido na literatura epistemológica contemporânea com um problema que nasce de duas formas distintas. O propósito deste ensaio é mostrar que essas supostas maneiras diferentes de gerar o mesmo problema em verdade originam dois problemas distintos, que requerem respostas distintas. Um deles está relacionado à aquisição fácil (inaceitável) de conhecimento de primeira-ordem e o outro à aquisição fácil (inaceitável) de conhecimento de segunda-ordem. Além disso, é apresentada a maneira como o infinitismo, a teoria (...) epistêmica segundo a qual as razões que justificam uma opinião devem ser infinitas em número e não-repetidas, pode lidar com cada um desses problemas.

Closure principles loom large in recent internalist critiques of epistemic externalism. Cohen (Philos Phenomenol Res 65:309–329, 2002, Philos Phenomenol Res 70:417–430, 2005), Vogel (J Philos 97:602–623, 2000), and Fumerton (Meta-Epistemology and skepticism. Rowman and Littlefield, Lanham, 1995) argue that, given closure, epistemic externalism is committed to the possibility of implausibly easy knowledge. By contrast, Zalabardo (Philos Rev 114:33–61, 2005) proposes that epistemic closure actually precludes the possibility of easy knowledge, and appeals to closure principles to solve (...) the problem of easy knowledge. In my view, disagreement over closure’s bearing on externalism and the problem of easy knowledge is rooted in a failure to bear in mind the familiar distinction between ex ante and ex post forms of epistemic justification and warrant. When this distinction is kept in focus, the result is clear: epistemic closure provides no relief from the problem of easy knowledge. (shrink)

In this paper I defend the theory that knowledge is credit-worthy true belief against a family of objections, one of which was leveled against it in a recent paper by Jennifer Lackey. In that paper, Lackey argues that testimonial knowledge is problematic for the credit-worthiness theory because when person A comes to know that p by way of the testimony of person B, it would appear that any credit due to A for coming to believe truly that p (...) belongs to the testifier, B, rather than the hearer, A. If so, then knowledge would appear not to be a matter of credit for true belief. I think that the problem this raises actually has little to do with the fact that the knowledge comes by way of testimony, and that similar objections can be formulated in terms of perceptual and memorial knowledge. I will attempt to neutralize these objections by drawing a distinction between credit as praiseworthiness and credit as attributability. (shrink)

It has recently been argued that any epistemological theory that allows for what is called basic knowledge, viz., knowledge that an agent acquires from a certain source, even if he fails to know that the source is reliable, falls victim to what is known as the problem of easy knowledge. The idea is that for such theories bootstrapping and closure allow us far too easily to acquire knowledge (justification) that seems unlikely under the envisaged (...) circumstances. In this paper, I begin by highlighting the distinction between the (epistemic) legitimacy and dialectical effectiveness of such inferences. After evaluating some of the well-known solutions to this problem, I offer a mixed view of the legitimacy of easy knowledge inferences while trying to provide novel explanations as to how contrary intuitions arise.

The problem of easy knowledge arises for theories that have what I call a “basic knowledge structure”. S has basic knowledge of P just in case S knows P prior to knowing that the cognitive source of S's knowing P is reliable.1 Our knowledge has a basic knowledge structure (BKS) just in case we have basic knowledge and we come to know our faculties are reliable on the basis of our basic (...) class='Hi'>knowledge. The problem I raised in “Basic Knowledge and the Problem of Easy Knowledge”2 (BKEK) is that once we allow for basic knowledge, we can come to know our faculties are reliable in ways that intuitively are too easy. This raises a serious doubt about whether we had the basic knowledge in the first place. In “Easy Knowledge”, Peter Markie argues that BKS theories do not face any problem concerning easy knowledge.3 I argued that the problem arises in two forms, and Markie takes issue with both. I will argue that Markie's defense of BKS theories fails. (shrink)

Professor Ayer's new book 1 is of very great interest. All the discussion is skilful, much of it is ingenious; the arguments ramify, but never get out of control; the prose is pleasant, the presentation polished and civilized. Once before, Professor Ayer investigated the foundations of empirical knowledge; and the central topics of his new book are, to a large extent, the same as those of his earlier one. These are topics which have been much discussed since 1940. Ayer (...) takes account of many of these discussions, and his views, in consequence, have changed. They have not changed quite so radically as one might have expected. Ayer thinks that the old-style sceptic ought still to be given a run on the old course against the old competitors. If I am not mistaken, it is important to keep this guiding thought in mind in trying to understand his book. For it is easy to glide comfortably over the smooth surface of this prose without noticing transitions and modulations which, in a less expertly composed treatise, might have given one a jolt.

Stewart Cohen has recently presented solutions to two forms of what he calls “The Problem of Easy Knowledge” (“Basic Knowledge and the Problem of Easy Knowledge,” Philosophy and Phenomenological Research, LXV, 2, September 2002, pp. 309‐329). I offer alternative solutions. Like Cohen's, my solutions allow for basic knowledge. Unlike his, they do not require that we distinguish between animal and reflective knowledge, restrict the applicability of closure under known entailments, or deny (...) the ability of basic knowledge to combine with self‐knowledge to provide inductive evidential support. My solution to the closure version of the problem covers a variation on the problem that is immune to Cohen's approach. My response to the bootstrapping version presents reasons to question whether the problem case, as Cohen presents it, is even possible, and, assuming it is, my solution avoids a false implication of Cohen's own. The key to my solutions for both versions is the distinction between an inference's transferring epistemic support, on the one hand, and its not begging the question against skeptics, on the other.

The material in this book is philosophically (as opposed to theologically or religiously) oriented, stressing the problem of God as a logical and philosophical problem. The perspective is critically analytic in the Naturalistic-Humanistic tradition. The basic approach is an issues or problems approach, but this is set in a historical context with quotations from Greek philosophy, the Church Fathers, the Medieval period, and from modern philosophers. The aim is to enable students to see what is being said and (...) has been said about God and thereby fits this into a better framework in the light of present knowledge and society. It is hoped that students will develop an awareness and appreciation of the philosophical problems in the concept of God, that they will acquire the ability to engage in intelligent evaluation and exchange of ideas, and that they will display these qualities in their everyday thought. This volume is by no means exhaustive of all the themes in the Philosophy of Religion. The most fundamental ones about God's existence are covered thoroughly. The book is a starting point for more intensive work in the subject. It lays down the basic groundwork for an easy transition to other topics and to more sophisticated thought-patterns. The writing has been kept as concise and elementary as possible with short sections on a variety of topics. (shrink)

According to externalist reliabilism and dogmatic foundationalism, it's possible to gain knowledge through a perceptual experience without being in a position to know that the experience is reliable. As a result, both of these views face the problem of making knowledge of perceptual reliability too easy, for they permit deducing perceptual reliability from particular perceptual experience without already knowing that these experiences are trustworthy. Ernest Sosa advocates a two-stage solution to the problem. At the first (...) stage, a rich body of perceptual animal knowledge is acquired. At the second stage, perceptual knowledge becomes reflective after deducing perceptual reliability from the initial body of perceptual animal knowledge. I defend the alternative approach of rejecting both externalist reliabilism and dogmatic foundationalism. According to the alternative view, perceptual knowledge and knowledge of perceptual reliability require each other. Such a cognitive structure seems viciously circular. I propose that the appearance of vicious circularity dissipates when the relationship in question is viewed, not as one of temporal priority, but instead as synchronic mutual dependence. At a given time, one cannot have perceptual knowledge without knowledge of perceptual reliability, and vice versa. Such mutual dependence, I argue, is benign. (shrink)

O problema do critério é um dos mais importantes da epistemologia. A resposta que se dá a ele definirá um aspecto fundamental das teorias do conhecimento. Neste ensaio, o problema do critério é apresentado e algumas das conseqüências geradas pela aceitação de exigências metaepistemicas são analisadas. Em especial, essas conseqüências são avaliadas em relação ao infinitismo – a teoria epistemológica segundo a qual as razões que sustentam nossas crenças devem ser infinitas em número e não-repetidas. Ao final, sustenta-se que cláusulas (...) que exigem que a metajustificação seja necessária para o conhecimento não apenas tornam as teorias epistemológicas mais plausíveis, mas também que a ausência de tais exigências acaba criando problemas muito difíceis, como o assim chamado “problema do conhecimento fácil”. PALAVRAS-CHAVE – Infinitismo. Problema do critério. Metajustificação. Conhecimento. Metaconhecimento. Ceticismo. ABSTRACT This essay discusses the Problem of the Criterion, one of the most important problems in Epistemology. The answer given to this problem will shape a fundamental aspect of theories of knowledge. It also analyzes some of the consequences epistemological theories may face in accepting metaepistemological requirements. These consequences are given special consideration with regard to Infinitism, the epistemological theory according to which the reasons that support our beliefs must be infinite and non-repeating. Finally, this essay claims not only that those propositions that require metajustification make any theory, even Infinitism, more plausible, but also that the absence of such requirements creates difficult problems, such as the so-called “Problem of Easy Knowledge.” KEY WORDS – Infinitism. Problem of the Criterion. Metajustification. Knowledge. Metaknowledge. Skepticism. (shrink)

This article aims to provide a structural analysis of the problems related to the easy knowledge problem. The easy knowledge problem is well known. If we accept that we can have basic knowledge via a source without having any prior knowledge about the reliability or accuracy of this source, then we can acquire knowledge about the reliability or accuracy of this source too easily via information delivered by the source. Rejecting any (...) kind of basic knowledge, however, leads into an infinite regress and, plausibly, to skepticism. The article argues that the third alternative, accepting basic knowledge but rejecting easy knowledge, entails closure failure. This is obviously the case for deductive bootstrapping, but, notably, the problem also arises for inductive bootstrapping. Hence, the set of problems related to the easy knowledge problem has the structure of a trilemma. We are forced to accept easy knowledge, closure failure, or skepticism. (shrink)

Stewart Cohen argues that basic knowledge is problematic, as it implies that subjects can acquire knowledge or justified beliefs about certain matters in ways that are supposedly too easy. Cohen raises two versions of the problem of easy knowledge, one involving the principle of closure and the other track-record style bootstrapping reasoning. In this paper I confront the problem of easy knowledge from the perspective of epistemological disjunctivism about perception. I argue (...) that disjunctivism can do a better job than dogmatism at responding to the version of the problem involving closure. I also argue that while disjunctivism would permit subjects to bootstrap their way to justified beliefs about the reliability of their perceptual powers, the disjunctivist can distinguish in a principled manner between this sort of bootstrapping and instances of it that we should agree are objectionable.

How do we transmit or distribute knowledge, as distinct from generating or producing it? In this book John Greco examines the interpersonal relations and social structures which enable and inhibit the sharing of knowledge within and across epistemic communities. Drawing on resources from moral theory, the philosophy of language, action theory and the cognitive sciences, he considers the role of interpersonal trust in transmitting knowledge, and argues that sharing knowledge involves a kind of shared agency similar (...) to giving a gift or passing a ball. He also explains why transmitting knowledge is easy in some social contexts, such as those involving friendship or caregiving, but impossible in contexts characterized by suspicion and competition rather than by trust and cooperation. His book explores phenomena that have been undertheorized by traditional epistemology, and throws new light on existing problems in social epistemology and the epistemology of testimony. (shrink)

This paper contrasts David Chalmers’s formulation of the easy and hard problems of consciousness with a Cartesian formulation. For Chalmers, the easy problem is making progress in explaining cognitive functions and discovering how they arise from physical processes in the brain. The hard problem is accounting for why these functions are accompanied by conscious experience. For Descartes, the easy problem is knowing the essential features of conscious experience. The hard problem is verifying our (...) knowledge of the mathematical—physical world. While Chalmers admits that consciousness as subjective experience has something irreducible about it, he also presupposes that conscious experience arises from physical processes. These physical processes are posited as objectively real entities given prior to human experience. The knowledge of such entities is assumed without theoretical justification. This assumption arguably invites a reductive materialist theory of mind. I suggest that employing the Cartesian method to articulate the representational theory of knowledge provides an antidote to reductive materialism and illuminates the conceptual gap between physical processes and conscious experience. To illustrate this I contrast Dennett’s heterophenomenology with the Cartesian method of crossing the conceptual gap. I suggest that the hard problem is attaining a knowledge of the extra-mental physical objects, not of conscious experience. (shrink)

Reliabilism furnishes an account of basic knowledge that circumvents the problem of the given. However, reliabilism and other epistemological theories that countenance basic knowledge have been criticized for permitting all-too-easy higher-level knowledge. In this paper, I describe the problem of easy knowledge, look briefly at proposed solutions, and then develop my own. I argue that the easy knowledge problem, as it applies to reliabilism, hinges on a false and too (...) crude understanding of ‘reliable’. With a more plausible conception of ‘reliable’, a simple and elegant solution emerges. (shrink)

Although several important methodologies implicitly assume the truth of epistemic conservatism, the view that holding a belief confers some measure of justification on the belief, recent criticisms have led some to conclude that epistemic conservatism is an implausible view. That conclusion is mistaken. In this article, I propose a new formulation of epistemic conservatism that is not susceptible to the criticisms leveled at earlier formulations of epistemic conservatism. In addition to withstanding these criticisms, this formulation of epistemic conservatism has several (...) benefits. First, this formulation has the benefits of earlier formulations of epistemic conservatism, that is to say it makes sense of our intuitions about justification in regard to both memory beliefs and beliefs for which we have forgotten our evidence. Second, it provides a good way of responding to the skeptic’s challenge concerning the possibility of possessing knowledge of the external world posed by the Alternative Hypotheses argument. Third, it provides responses to both forms of a new skeptical problem plaguing basic knowledge structure theories, the Problem of Easy Knowledge formulated by Stewart Cohen. I argue that given the many benefits of this formulation of epistemic conservatism and the fact that it is not vulnerable to the criticisms that undermine earlier formulations of epistemic conservatism, this formulation of epistemic conservatism is a plausible view to maintain.

The central question of this article is how to combine counterfactual theories of knowledge with the notion of actuality. It is argued that the straightforward combination of these two elements leads to problems, viz. the problem of easy knowledge and the problem of missing knowledge. In other words, there is overgeneration of knowledge and there is undergeneration of knowledge. The combination of these problems cannot be solved by appealing to methods by which (...) beliefs are formed. An alternative solution is put forward. The key is to rethink the closeness relation that is at the heart of counterfactual theories of knowledge. (shrink)

The Charmides is among Plato's most intriguing and perplexing dialogues. The range of subjects touched or treated is extremely wide: matters logical, epistemological, moral, ethical, political, and religious. In many cases, these are discussed in a highly inconclusive and aporetic way, especially when it comes to the subject of knowledge. Finally, the dialogue is also difficult on almost every level of its expression; mock-reasonings, misunderstandings, ironies, paradoxes, and perplexities abound. As a result, the run of its many arguments, both (...) on the short and the long range, and its overall structure are not easy to discern. If a text of such a character is to be made completely accessible, a full-scale commentary is required; it is much to be regretted, therefore, that there is no commentary in which the difficulties of the Greek, the argument, and the place of the philosophical problems in the development of Plato's thought are comprehensively and coherently explained. This monograph does not aspire to that status, but makes an essential contribution towards achieving that aim (in addition to the many other works in the field, Lamb's scrupulous translation of 1927 and Bloch's penetrating study of 1973 in particular) by presenting a detailed examination of forty-two passages of which the interpretation is disputed; many more minor problems are dealt with along the way. In all matters of interpretation, special attention has been paid to defining the exact place of the passage within the run of the, often intricate, argument. The result of this attention can also be observed in an analytical 'Summary of the contents of the Charmides'. (shrink)

He then argues that (1), (2) and (3) constitute an inconsistent triad as follows (1991, p. 15): Suppose (1) that Oscar knows a priori that he is thinking that water is wet. Then by (2), Oscar can simply deduce E, using premisses that are knowable a priori, including the premiss that he is thinking that water is wet. Since Oscar can deduce E from premisses that are knowable a priori, Oscar can know E itself a priori. But this contradicts (3), (...) the assumption that E cannot be known a priori. Hence (1), (2), and (3) are inconsistent. McKinsey’s conclusion is that ‘anti-individualism is inconsistent with privileged access’ (ibid.). (shrink)

When one recalls that P, how is one justified in believing that P? I refute the three most natural answers to this question: a memory belief is not justified by a belief in the reliability of memory; a memory experience does not provide a new, foundational justification for a belief; and memory does not merely preserve the same justification a belief had when first adopted. Instead, the justification of a memory belief is a product of both the initial justification for (...) adopting it and the justification for retaining it provided by seeming memories. (shrink)

This chapter reviews a number of related problems in the epistemology of testimony, and suggests some dilemmas for any theory of knowledge that tries to solve them. Here a common theme emerges: It can seem that any theory must make testimonial knowledge either too hard or too easy, and that therefore no adequate account of testimonial knowledge is possible. The chapter then puts forward a proposal for making progress. Specifically, an important function of the concept of (...) knowledge is to govern the acquisition and distribution of quality information within an epistemic community. Testimonial exchanges paradigmatically serve in the distribution role, but sometimes serve in the acquisition role. The resulting position, it is argued, explains why testimonial knowledge is sometimes easy to get, and sometimes much harder. (shrink)

The article concerns the meta-epistemological problem of the justification of a theory of knowledge and provides a reconstruction of the history of its formulations.

Traditionally it has been thought that the moral valence of a proposition is, strictly speaking, irrelevant to whether someone knows that the proposition is true, and thus irrelevant to the truth-value of a knowledge ascription. On this view, it’s no easier to know, for example, that a bad thing will happen than that a good thing will happen (other things being equal). But a series of very surprising recent experiments suggest that this is actually not how we view (...) class='Hi'>knowledge. On the contrary, people are much more willing to ascribe knowledge of a bad outcome. This is known as the epistemic side-effect effect (ESEE), and is a specific instance of a widely documented phenomenon, the side-effect effect (a.k.a. “the Knobe effect”), which is the most famous finding in experimental philosophy. In this paper, I report a new series of five experiments on ESEE, and in the process accomplish three things. First, I confirm earlier findings on the effect. Second, I show that the effect is virtually unlimited. Third, I introduce a new technique for detecting the effect, which potentially enhances its theoretical significance. In particular, my findings make it more likely that the effect genuinely reflects the way we think about and ascribe knowledge, rather than being the result of a performance error. (shrink)

This book addresses the problem of self-knowledge in Kant’s philosophy. As Kant writes in his major works of the critical period, it is due to the simple and empty representation ‘I think’ that the subject’s capacity for self-consciousness enables the subject to represent its own mental dimension. This book articulates Kant’s theory of self-knowledge on the basis of the following three philosophical problems: 1) a semantic problem regarding the type of reference of the representation ‘I’; 2) (...) an epistemic problem regarding the type of knowledge relative to the thinking subject produced by the representation ‘I think’; and 3) a strictly metaphysical problem regarding the features assigned to the thinking subject’s nature. The author connects the relevant scholarly literature on Kant with contemporary debates on the huge philosophical field of self-knowledge. He develops a formal reading according to which the unity of self-consciousness does not presuppose the identity of a real subject, but a formal identity based on the representation ‘I think’.

Suppose Ted is in an ordinary house in good viewing conditions and believes red, his table is red, entirely because he sees his table and its color; he also believes not-white, it is false that his table is white and illuminated by a red light, because not-white is entailed by red. The following three claims about this table case clash, but each seems plausible: 1. Ted’s epistemic position is strong enough for him to know red. 2. Ted cannot know not-white (...) on the basis of red. 3. The epistemic closure principle, suitably restricted, is true. Stewart Cohen has called this three-way clash of intuitions the problem of easy knowledge. If we wish to resolve the clash without accepting skepticism, we seem to have two options. According to the hard argument, the best response is to reject 3. The easy argument rejects 2. But there may be a third alternative, the reverse argument, which rejects 1 without ceding a substantial amount of ground to the skeptic. In this essay I criticize recent versions of the reverse argument and the hard argument, thereby lending support to the easy argument. (shrink)

Real-world agents do not know all consequences of what they know. But we are reluctant to say that a rational agent can fail to know some trivial consequence of what she knows.

Rather, a solution must give adequate weight to the normative requirements on rational agents’ epistemic states, without treating those agents as mathematically ideal reasoners. I’ll (...) argue that agents can fail to know trivial consequences of what they know, but never determinately. Such cases are epistemic oversights on behalf of the agent in question, and the facts about epistemic oversights are always indeterminate facts. As a result, we are never in a position to assert that such-and-such constitutes an epistemic oversight for agent i (for we may rationally assert only determinate truths). I then develop formal epistemic models according to which epistemic accessibility relations are vague. Given these models, we can show that epistemic oversights always concern indeterminate cases of knowledge. (shrink)

Offers a diagnosis of the easy knowledge problem, according to which easy knowledge is unjustified belief because the inferences that deliver easy knowledge feign evidential support that is not actually there. This diagnosis leads to a rejection of Closure. But, I argue, this rejection of Closure is more plausible than the traditional one endorsed by tracking theorists. I also argue that my diagnosis suggests a general plausibility argument against Closure, since a number of (...) epistemic goods traditionally associated with knowledge do not transfer across known entailments. Finally, I defend Anti-Closure against two recent objections. (shrink)

The early essays in this volume proceed on the assumption that a compatability system can be fashioned that will not only bring religious knowledge claims into harmony with scientific claims, but will also show there to be a fundamental similarity of method in religious and scientific thinking. They are not, however, unambiguously successful. Consequently Wiebe sets out in the succeeding essays to seek an understanding of the religion/science relationship that does not assume they must be compatible. The examination, in (...) the final analysis, reveals a fundamental contradiction in the compatability system building programme which suggests that religious belief is beyond legitimation. (shrink)

Background: Dengue Disease is a mosquito-borne tropical disease caused by the dengue virus, symptoms typically begin three to fourteen days after infection.
