The Problem of Easy Knowledge

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.

This paper aims at resolving a puzzle about the persuasiveness of bootstrapping. On the one hand, bootstrapping is not a persuasive method of settling questions about the reliability of a source. On the other hand, our beliefs that our sense apparatus is reliable is based on other empirically formed beliefs, that is, they are acquired via a presumably complex bootstrapping process. I will argue that when we doubt the reliability of a source, bootstrapping is not a persuasive method for coming (...) to believe that the source is reliable. However, when being initially unaware of a source and its reliability, as in the case of forming beliefs about our sense apparatus, bootstrapping can be eventually persuasive. (shrink)

Knowledge closure is the claim that, if an agent S knows P, recognizes that P implies Q, and believes Q because it is implied by P, then S knows Q. Closure is a pivotal epistemological principle that is widely endorsed by contemporary epistemologists. Against Knowledge Closure is the first book-length treatment of the issue and the most sustained argument for closure failure to date. Unlike most prior arguments for closure failure, Marc Alspector-Kelly's critique of closure does not presuppose any particular (...) epistemological theory; his argument is, instead, intuitively compelling and applicable to a wide variety of epistemological views. His discussion ranges over much of the epistemological landscape, including skepticism, warrant, transmission and transmission failure, fallibilism, sensitivity, safety, evidentialism, reliabilism, contextualism, entitlement, circularity and bootstrapping, justification, and justification closure. As a result, the volume will be of interest to any epistemologist or student of epistemology and related subjects. (shrink)

In this chapter I investigate epistemological consequences of the fact that seeming-based justification is elusive, in the sense that the subject can lose this justification simply by reflecting on her seemings. I argue that since seeming-based justification is elusive, the antisceptical bite of phenomenal conservatism is importantly limited. I also contend that since seeming-based justification has this feature, phenomenal conservatism isn’t actually afflicted by easy justification problems.

Reliabilism is an intuitive and attractive view about epistemic justification. However, it has many well-known problems. I offer a novel condition on reliabilist theories of justification. This method coherence condition requires that a method be appropriately tested by appeal to a subject’s other belief-forming methods. Adding this condition to reliabilism provides a solution to epistemic circularity worries, including the bootstrapping problem.

This is a survey article about reliabilism. It introduces its main ideas, outlines some of its core challenges and discusses a number of solutions.

Arguments from "easy knowledge" are meant to refute a class of epistemological views, including foundationalism about perceptual knowledge. I present arguments from easy knowledge in their strongest form, and explain why other formulations in the literature are inferior. I criticize two features of Stewart Cohen's presentation, namely his focus on knowing that one's faculties are reliable, and his use of a Williamson-style closure principle. Rather, the issue around easy knowledge must be understood using a notion of epistemic priority. Roger White's (...) presentation is contaminated by the so-called lottery puzzle, which is best kept separate. Distinguishing basic from non-basic visual contents limits the force of the examples discussed by Cohen, White, and Crispin Wright. Finally, I present a new strategy for resisting even the best-formulated arguments from easy knowledge. (shrink)

This book is primarily about checking and only derivatively about knowing. Checking is a very common concept for describing a subject’s epistemic goals and actions. Surprisingly, there has been no philosophical attention paid to the notion of checking. In Part I, I develop a sensitivity account of checking. To be more explicit, I analyze the internalist and externalist components of the epistemic action of checking which include the intentions of the checking subject and the necessary externalist features of the method (...) used. Crucially, successfully checking whether p is true requires using a method that is sensitive with respect to p, i.e. a method that would not indicate that p, if p were false. In Part II, I use the distinction between knowing and checking to explain central puzzles about knowledge, particularly puzzles centering on knowledge closure, puzzles concerning bootstrapping and the skeptical puzzle. Moreover, the book clarifies a dispute about modal epistemology, concerning the application of the sensitivity principle. By arguing that sensitivity is necessary for checking but not knowing, I explain where our persisting intuitions about sensitivity have their place in epistemology. (shrink)

To solve the ancient Pyrrhonian problematic, it is not enough to show that knowledge and justified belief are possible. They must be shown to be actual. It is argued that the attempts by the main advocates of reliabilism, William Alston, Alvin Goldman, and Ernest Sosa, fail to solve the problematic because they fall under the Agrippan modes of circularity and hypothesis. There is also another sort of response implicit in their discussion. It is not to try to solve the problematic, (...) but to accept the Pyrrhonian moral and to settle for appearances. Finally, a version of Pyrrhonism is given, and it is suggested that reliabilism be understood as a case of this sort of Pyrrhonism. (shrink)

Reliabilists have often noticed a kind of circularity in their reasoning, but they have insisted that the circularity in question is not vicious. On the contrary, they think typically that reliabilism resolves even the traditional problems of circularity. It is argued in the paper that there is a real problem of circularity that relates to the method by which we are supposed arrive at our epistemology. Different methods are considered, including methodism and particularism that Roderick Chisholm distinguishes as possible responses (...) to the problem of the criterion and the method of reflective equilibrium due to Nelson Goodman and John Rawls. It is argued that only the method of wide reflective equilibrium (WRE) doesn't cause serious problems for reliabilism. Then it is argued that the method of WRE can actually be seen as the method of epistemology of which the approaches discussed earlier are just different versions. Finally, it is pointed out that the source of the troubles with circularity lies actually in certain non-epistemic background assumptions, that are therefore discarded. This brings reliabilism closer to the commonsense tradition and its characteristic anti-skepticism. (shrink)

This is a critical discussion of a paper on the problem of bootstrapping by Jose Zalabardo.

In this paper, I defend the heterogeneity problem for sensitivity accounts of knowledge against an objection that has been recently proposed by Wallbridge in Philosophia. I argue in, 479–496, 2015) that sensitivity accounts of knowledge face a heterogeneity problem when it comes to higher-level knowledge about the truth of one’s own beliefs. Beliefs in weaker higher-level propositions are insensitive, but beliefs in stronger higher-level propositions are sensitive. The resulting picture that we can know the stronger propositions without being in a (...) position to know the weaker propositions is too heterogeneous to be plausible. Wallbridge objects that there is no heterogeneity problem because beliefs in the weaker higher-level propositions are also sensitive. I argue against Wallbridge that the heterogeneity problem is not solved but only displaced. Only some beliefs in the weaker higher-level propositions are sensitive. I conclude that the heterogeneity problem is one of a family of instability problems that sensitivity accounts of knowledge face and that Wallbridge’s account raises a further problem of this kind.

Juan Comesaña and Carolina Sartorio have recently proposed a diagnosis of what goes wrong in apparently illegitimate cases of ‘bootstrapping’ one’s way toexcessively easy knowledge. They argue that in such cases the bootstrapper bases at least one of her beliefs on evidence that does not evidentially support the proposition believed. I explicate the principle that underlies Comesaña and Sartorio’s diagnosis of such cases and show that their account of what goes wrong in such cases is mistaken.

We have recently proposed a diagnosis of what goes wrong in cases of ‘easy-knowledge.’ Erik Wielenberg argues that there are cases of easy knowledge thatour proposal cannot handle. In this note we reply to Wielenberg, arguing that our proposal does indeed handle his cases.

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. Our knowledge has a basic knowledge structure just in case we have basic knowledge and we come to know our faculties are reliable on the basis of our basic knowledge. The problem I raised in "Basic Knowledge and the (...) Problem of Easy Knowledge" 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. (shrink)

Stewart Cohen considers a case where his son wants a red table for his room. Cohen and his son go to the furniture store. Cohen’s son is concerned that the table his father is considering purchasing, which appears red, may in fact be white with red lights shining on it. Cohen responds with the following reasoning: The table looks red. The table is red. If the table is red, then it is not white with red lights shining on it. The (...) table is not white with red lights shining on it. If one reasons thus, say one’s engaged in -reasoning. Cohen finds such a response unsatisfactory. It is not a way of coming to know —it is too easy. And structurally similar reasoning delivers the falsity of sceptical hypotheses concerning the external world, testimony, other minds etc. So the unsatisfactoriness threatens to generalise. I consider Martin Davies ’s attempt to diagnose this unsatisfactoriness and find it incomplete. I then attempt to remedy the incompleteness in Davies ’s attempt. (shrink)

Comprehensive Linguistic Approach to Frege's Commitment Puzzle There is a puzzle, noticed by Frege, about inferences from sentences like (F1) "Jupiter has four moons" to sentences like (F2) "The number of moons of Jupiter is four". They seem to be truth-conditionally equivalent but, apparently, they say something about completely different things. (F1) seems to be about moons, while (F2) about numbers. This phenomenon raises several puzzles about semantics, syntax, and is one of main tools of easy ontology. Recently, new linguistic (...) and pragmatic solutions were proposed. Linguistic solutions of Thomas Hofweber and Katharina Felka are refreshed versions of the traditional paraphrastic approach that involve consideration of conversational contexts as well as syntactical structure of copular sentences. The pragmatic solution resorts to bracketing or indifference to certain possible alternatives and contexts of a sentence. I discuss their strong and weak points and propose to include in further research John Biro's account of the expression "the number of planets", which solves the problems of the new linguistic approaches.

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)

The bootstrapping problem poses a general challenge, afflicting even strongly internalist theories. Even if one must always know that one’s source is reliable to gain knowledge from it, bootstrapping is still possible. I survey some solutions internalists might offer and defend the one I find most plausible: that bootstrapping involves an abuse of inductive reasoning akin to generalizing from a small or biased sample. I also argue that this solution is equally available to the reliabilist. The moral is that the (...) issues raised by bootstrapping are orthogonal to questions about internalism and basic knowledge, having more to do with the nature of good inductive reasoning. (shrink)

Offering a solution to the skeptical puzzle is a central aim of Nozick's sensitivity account of knowledge. It is well-known that this account faces serious problems. However, because of its simplicity and its explanatory power, the sensitivity principle has remained attractive and has been subject to numerous modifications, leading to a of sensitivity accounts. I will object to these accounts, arguing that sensitivity accounts of knowledge face two problems. First, they deliver a far too heterogeneous picture of higher-level beliefs about (...) the truth or falsity of one's own beliefs. Second, this problem carries over to bootstrapping and Moorean reasoning. Some beliefs formed via bootstrapping or Moorean reasoning are insensitive, but some closely related beliefs in even stronger propositions are sensitive. These heterogeneous results regarding sensitivity do not fit with our intuitions about bootstrapping and Moorean reasoning. Thus, neither Nozick's sensitivity account of knowledge nor any of its modified versions can provide the basis for an argument that bootstrapping and Moorean reasoning are flawed or for an explanation why they seem to be flawed.

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.

Can a belief source confer justification when we lack antecedent justification for believing that it’s reliable? A negative answer quickly leads to skepticism. A positive answer, however, seems to commit one to allowing pernicious reasoning known as “epistemic bootstrapping.” Puzzles surrounding bootstrapping arise because we illicitly assume either that justification requires doxastic awareness of a source’s epistemic credentials or that there is no requirement that a subject be aware of these credentials. We can resolve the puzzle by splitting the horns (...) and requiring a non-conceptual awareness of, or direct acquaintance with, a source’s legitimacy. Requiring non-conceptual as opposed to doxastic awareness halts the regress and avoids the skeptical results. On the other hand, requiring non-conceptual awareness also guarantees that we are aware of evidence for a source’s reliability prior to using that source to form justified beliefs; we thereby avoid the problem of allowing epistemic bootstrapping to generate the illicit gains in justification.

I will compare Lehrer’s anti-skeptical strategy from a coherentist point of view with the anti-skeptical strategy of the Mooreans. I will argue that there are strong similarities between them: neither can present a persuasive argument to the skeptic and both face the problem of easy knowledge in one way or another. However, both can offer a complete and self-explanatory explanation of knowledge although Mooreanism can offer the more natural one. Hence, one has good reasons to prefer Mooreanism to Lehrer’s anti-skeptical (...) approach, if one does not prefer coherentism to foundationalism for other reasons. (shrink)

Reflective Knowledge draws together ground-breaking work in epistemology by Ernest Sosa. He argues for a reflective virtue epistemology based on virtuous circularity, shows how this idea may be found explicitly or just below the surface in such illustrious predecessors as Descartes and Moore, and defends the view against its rivals.

In “Reliabilism Leveled” Jonathan Vogel (2000) provides a strong case against epistemic theories that stress the importance of tracking/sensitivity conditions. A tracking/sensitivity condition is to be understood as some version of the following counterfactual: (T) ~p oÆ ~Bp (T) says that s would not believe p, if p were false. Among other things, tracking is supposed to express the external relation that explains why some justified true beliefs are not knowledge. Champions of the condition include Robert Nozick (1981) and, more (...) recently, Keith DeRose (1995). To my knowledge, the earliest formulation of the counterfactual condition is found in Fred Dretske’s conclusive reasons condition (1971), which says, s would not have had the reason that she does for believing p, if p were false. Vogel contends that any such counterfactual condition on knowledge will render the theory of knowledge too strong. He believes that there is at least some possible reflective knowledge that cannot satisfy the counterfactual--viz., the possible knowledge that one does not believe falsely that p. The alleged impossibility of such reflective knowledge is taken by Vogel to be a decisive objection to the tracking theories advocated by Dretske, Nozick, DeRose1 and others. The criticism finds its roots in Vogel’s earlier work (1987), and recurs in papers by Ernest Sosa (2002, 1996). Sosa suggests that the externalist idea behind tracking is on target, but that Nozick’s counterfactual is a misbegotten regimentation of the idea. In its place Sosa offers his own counterfactual “safety” condition, which he feels properly captures the externalist idea. Sosa’s counterfactual is not the topic of this paper. I mention it only to point out that the criticism that constitutes the subject of my investigation is meant to do a lot of work. In Sosa’s 1 case the criticism is meant to motivate his own counterfactual analysis, and in Vogel’s case the criticism promises to be a silver bullet against a theory that has recently found renewed life in the work of Keith DeRose..

The present paper aims to revisit the virtues and disadvantages of epistemic conservatism, which claims that it is rational to adhere to a belief until there is evidence to the contrary. Two main theses are put forward: first, while conservatism presents several epistemological flaws, from a contextualist point of view it is not only desirable but also is essential to knowledge accumulation in everyday life; second, conservatism provides a solution to sceptical challenges and to the problem of easy knowledge.

Stewart Cohen (2002; 2005) considers a case where his son wants a red table for his room. Cohen and his son go to the furniture store. Cohen’s son is concerned that the table his father is considering purchasing, which appears red, may in fact be white with red lights shining on it. Cohen responds with the following reasoning:(WARRANT FOR 1) The table looks red.(EK) (1) The table is red.(2) If the table is red, then it is not white with red (...) lights shining on it.(3) The table is not white with red lights shining on it.If one reasons thus, say one’s engaged in EK-reasoning. Cohen finds such a response unsatisfactory. It is not a way of coming to know (3)—it is too easy. And structurally similar reasoning delivers (knowledge of) the falsity of sceptical hypotheses concerning the external world, testimony, other minds etc. So the unsatisfactoriness threatens to generalise. I sketch (one strand of) José Zalabardo’s (2005) original and heterodox attempt to diagnose this unsatisfactoriness, and explore its upshots. (shrink)

Reliabilism is a theory that countenances basic knowledge, that is, knowledge from a reliable source, without requiring that the agent knows the source is reliable. Critics (especially Cohen 2002 ) have argued that such theories generate all-too-easy, intuitively implausible cases of higher-order knowledge based on inference from basic knowledge. For present purposes, the criticism might be recast as claiming that reliabilism implausibly generates cases of understanding from brute, basic knowledge. I argue that the easy knowledge (or easy understanding) criticism rests (...) on an implicit mischaracterization of the notion of a reliable process. Properly understood, reliable processes do not permit the transition from basic knowledge to understanding based on inference. (shrink)

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)

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.

In this paper I defend epistemic circularity by arguing that the “No Self-Support” principle (NSS) is false. This principle, ultimately due to Fumerton ( 1995 ), states that one cannot acquire a justified belief in the reliability of a source of belief by trusting that very source. I argue that NSS has the skeptical consequence that the trustworthiness of all of our sources ultimately depends upon the trustworthiness of certain fundamental sources – sources that we cannot justifiably believe to be (...) reliable. This is a problem, I claim, because if the trustworthiness of all of our sources depends upon sources that we should not believe to be reliable, then a reflective individual should not trust any of his sources at all. The hidden cost of rejecting epistemic circularity is thus the unacceptable skeptical thesis that reflective individuals like you and I have no justified beliefs whatsoever. (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)

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”.

If the reliability of a source of testimony is open to question, it seems epistemically illegitimate to verify the source’s reliability by appealing to that source’s own testimony. Is this because it is illegitimate to trust a questionable source’s testimony on any matter whatsoever? Or is there a distinctive problem with appealing to the source’s testimony on the matter of that source’s own reliability? After distinguishing between two kinds of epistemically illegitimate circularity—bootstrapping and self-verification—I argue for a qualified version of (...) the claim that there is nothing especially illegitimate about using a questionable source to evaluate its own reliability. Instead, it is illegitimate to appeal to a questionable source’s testimony on any matter whatsoever, with the matter of the source’s own reliability serving only as a special case. (shrink)

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)

Abstract This paper examines the kind of epistemic circularity which, according to Ernest Sosa, is unavoidably entailed whenever one has what he calls ?reflective? knowledge (that is, knowledge that p such that the knower reflectively endorses the reliability of the epistemic sources by which she came to her belief that p). I begin by describing the relevant kind of circularity and its role in Sosa's epistemology, en route presenting and resisting Sosa's arguments that this kind of circularity is not vicious. (...) Then I consider the somewhat complex relationship between Sosa's views on epistemic circularity and his response to the Problem of Easy Knowledge, arguing that (on one interpretation of Sosa, at least) a complete solution to that problem cannot be extracted from Sosa's work unless the aforementioned epistemic circularity can be proved non-vicious.

Pretheoretically we hold that we cannot gain justification or knowledge through an epistemically circular reasoning process. Epistemically circular reasoning occurs when a subject forms the belief that p on the basis of an argument A, where at least one of the premises of A already presupposes the truth of p. It has often been argued that process reliabilism does not rule out that this kind of reasoning leads to justification or knowledge. For some philosophers, this is a reason to reject (...) reliabilism. Those who try to defend reliabilism have two basic options: (I) accept that reliabilism does not rule out circular reasoning, but argue that this kind of reasoning is not as epistemically “bad” as it seems, or (II) hold on to the view that circular reasoning is epistemically “bad”, but deny that reliabilism really allows this kind of reasoning. Option (I) has been spelled out in several ways, all of which have found to be problematic. Option (II) has not been discussed very widely. Vogel considers and quickly dismisses it on the basis of three reasons. Weisberg has shown in detail that one of these reasons is unconvincing. In this paper I argue that the other two reasons are unconvincing as well and that therefore option (II) might in fact be a more promising starting point to defend reliabilism than option (I).

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)

Bootstrapping is a suspicious form of reasoning that verifies a source's reliability by checking it against itself. Theories that endorse such reasoning face the bootstrapping problem. This article considers which theories face the problem, and surveys potential solutions. The initial focus is on theories like reliabilism and dogmatism, which allow one to gain knowledge from a source without knowing that it is reliable. But the discussion quickly turns to a more general version of the problem that does not depend on (...) this allowance. Five potential solutions to the general problem are evaluated, and some implications for the literature on peer disagreement are considered. (shrink)

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. (shrink)

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)
