Contextualist Replies to Skepticism

Coping with everyday life limits the extent of one’s scepticism. It is practically impossible to doubt the existence of the things with which one is immediately engaged and interacting. To doubt that, say, a door exists, is to step back from merely using the door (opening it) and to reflect on it in a detached, theoretical way. It is impossible to simultaneously act and live immersed in situation S while doubting that one is in S. Sceptical doubts—such as ‘Is this (...) really a door?’, ‘Am I really walking?’ — require a reflective withdrawal in thought from the situation at hand. Maintaining sceptical doubt while coping with everyday life requires a split consciousness, a bad faith, with one part of consciousness doubting the existing of things that the other part takes forgranted. For this reason, a sustained lived sceptical doubt is sometimes thought to be impossible. -/- In this article, I examine Wittgenstein's response to scepticism in "On Certainty". I argue that one of his responses is "the response based on action", which is (as other Wittgenstein interpreters have noted) a characteristically pragmatist response. I then evaluate the quality of this pragmatist response to scepticism, noting that actions just as much as representations are susceptible to mis-interpretation. It is argued that despite the insights contained in it, Wittgenstein's contextualism about meaning is inadequate to rescue the Wittgensteinian response to scepticism. (shrink)

In this paper we propose a new semantics, based on the notion of a "contextual model", that makes it possible to express and compare — within a unique formal framework — different views on the roles of various notions of context in knowledge ascriptions. We use it to provide a logical analysis of such positions as skeptical and moderate invariantism, contextualism, and subject-sensitive invariantism. A dynamic formalism is also proposed that offers new insights into a classical skeptical puzzle.

This article discusses Keith DeRose’s treatment of the lottery problem in Chapter 5 of his recent The Appearance of Ignorance. I agree with a lot of it but also raise some critical points and questions and make some friendly proposals. I discuss different ways to set up the problem, go into the difference between knowing and ending inquiry, propose to distinguish between two different kinds of lotteries, add to the defense of the idea that one can know lottery propositions, give (...) a critical discussion of DeRose’s contextualist solution to the problem, and support his defense against an absurdity objection with additional arguments.

This interview was carried out on 13 December 2018 as Michael Williams was in Porto for a meeting of the Contextualism Network organised by the MLAG – Mind, Language, and Action Research Group (Institute of Philosophy of the University of Porto). We would like to thank him for his willingness to reply to our questions. -/- .

Keith DeRose’s new book The Appearance of Ignorance is a welcome companion volume to his 2009 book The Case for Contextualism. Where latter focused on contextualism as a view in the philosophy of language, the former focuses on how contextualism contributes to our understanding of some perennial epistemological problems, with the skeptical problem being the main focus of six of the seven chapters. DeRose’s view is that a solution to the skeptical problem must do two things. First, it must explain (...) how it is that we can know lots of things, such as that we have hands. Second, it must explain how it can seem that we don’t know these things. In slogan form, DeRose’s argument is that a contextualist semantics for knowledge attributions is needed to account for the “appearance of ignorance”—the appearance that we don’t know that skeptical hypotheses fail to obtain. In my critical discussion, I will argue inter alia that we don’t need a contextualist semantics to account for the appearance of ignorance, and in any case that the “strength” of the appearance of ignorance is unclear, as is the need for a philosophical diagnosis of it.

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)

This paper explores some consequences of Lewis’s (Australas J Philos 74(4):549–567, 1996) understanding of how knowledge is compartmentalized. It argues, first, that he underestimates how badly it impacts his view. When knowledge is compartmentalized, it lacks at least one of two essential features of Lewis’s account: (a) Elusiveness—familiar skeptical possibilities, when relevant, are incompatible with everyday knowledge. (b) Knowledge is a modality—when a thinker knows that p, there is no relevant possibility where p is false. Lewis proposes compartmentalized knowledge to (...) keep treating knowledge as a modality while mitigating one of its unrealistic epistemological implications: In normal modal epistemic logic (and standard possible world semantics), a thinker always counts as knowing the strongest proposition that follows from the set of all the individual propositions that this thinker knows. Lewis’s compartmentalization proposal is that thinkers merely know the conjunctions of propositions that are known in each of, but not across, their compartments. The irony is that in avoiding overblown knowledge the view now allows for thinkers to attend to skeptical error possibilities and yet knowledge is present. The account avoids inflation of knowledge in one sense only to acquire another type of knowledge the view denies subjects can have. This problem motivates an inspection of knowledge accounts whose intra-compartment closure principles are weaker than those that are valid in normal modal-logic. The conclusion is that some formulations of closure can avoid the challenge Lewis’s view faces. Nevertheless, even these closure principles pose a barrier—perhaps an implausible barrier—for knowledge of ignorance. Even when the reasoning supporting the lack of knowledge is sound, a subject cannot always know she doesn’t know. Interestingly, this obstacle is one that knowledge of knowledge doesn’t seem to face.

This is the second book by Baz that aims to show that a big chunk of contemporary philosophy is fundamentally misguided. His first book, When Words Are Called For: A Defense of Ordinary Language Philosophy (2012) adopted a therapeutic approach (in the Wittgensteinian style) to problems in contemporary epistemology, arguing that when properly thought through, the way philosophers talk about ‘knowing’ that something is the case ultimately does not make sense. Baz’s goal in his second book is less therapeutic and (...) more constructive: he aims to start a methodological revolution (in the Kuhnian sense)—to shake contemporary philosophers out of the unconscious habits of normal science and provoke them into making a radical change in the methods they use to do philosophy and the basic assumptions that motivate those methods.

The radical skeptic argues that I have no knowledge of things I ordinarily claim to know because I have no evidence for or against the possibility of being systematically fed illusions. Recent years have seen a surge of interest in pragmatic responses to skepticism inspired by C. S. Peirce. This essay challenges one such influential response and presents a better Peircean way to refute the skeptic. The account I develop holds that although I do not know whether the skeptical hypothesis (...) is true, I still know things I ordinarily claim to know. Although it will emerge that this reply appears similar to a classic contextualist response to radical skepticism, it avoids two central problems facing that response. (shrink)

Semantic contextualism is often used in order to offer solutions for problems in other branches of philosophy, including epistemology. One of such attempts is epistemic contextualism, according to which the semantic value of the word “knows” changes with the context of its utterance. The aim of this paper is to critically investigate Keith DeRose’s contextualism to see up to what extent does it provide a valid anti-sceptical strategy. I argue that while it can be seen as a good rival for (...) global and Ungerian scepticism, it does not lead to the refutation of other variants of classical scepticism. (shrink)

Epistemic Contextualism is the view that “knows that” is semantically context-sensitive and that properly accommodating this fact into our philosophical theory promises to solve various puzzles concerning knowledge. Yet Epistemic Contextualism faces a big—some would say fatal—problem: The Semantic Error Problem. In its prominent form, this runs thus: speakers just don’t seem to recognise that “knows that” is context-sensitive; so, if “knows that” really is context-sensitive then such speakers are systematically in error about what is said by, or how to (...) evaluate, ordinary uses of “S knows that p”; but since it's wildly implausible that ordinary speakers should exhibit such systematic error, the expression “knows that” isn't context-sensitive. We are interested in whether, and in what ways, there is such semantic error; if there is such error, how it arises and is made manifest; and, again, if there is such error to what extent it is a problem for Epistemic Contextualism. The upshot is that some forms of The Semantic Error Problem turn out to be largely unproblematic. Those that remain troublesome have analogue error problems for various competitor conceptions of knowledge. So, if error is any sort of problem, then there is a problem for every extant competitor view. (shrink)

According to some powerful skeptical arguments, we know almost nothing. Contextualist theories of knowledge ascriptions have been developed with an eye toward resisting skepticism. Have the contextualists succeeded? After briefly outlining their view, I will consider whether contextualism about knowledge ascriptions provides a satisfactory response to one of the most popular and influential forms of skepticism. I conclude with some questions for the contextualist. As we’ll see, the effectiveness of the contextualist solution to skepticism is far from settled.

The book develops and synthesises two main ideas: contextualism about knowledge ascriptions and a knowledge-first approach to epistemology. The theme of the book is that these two ideas fit together much better than it's widely thought they do. Not only are they not competitors: they each have something important to offer the other.

Objective: In this essay, I will try to track some historical and modern stages of the discussion on the Gettier problem, and point out the interrelations of the questions that this problem raises for epistemologists, with sceptical arguments, and a so-called problem of relevance. Methods: historical analysis, induction, generalization, deduction, discourse, intuition results: Albeit the contextual theories of knowledge, the use of different definitions of knowledge, and the different ways of the uses of knowledge do not resolve all the issues (...) that the sceptic can put forward, but they can be productive in giving clarity to a concept of knowledge for us. On the other hand, our knowledge will always have an element of intuition and subjectivity, however not equating to epistemic luck and probability. Significance novelty: the approach to the context in general, not giving up being a Subject may give us a clarity about the sense of what it means to say – “I know”. (shrink)

Resumo O Contextualismo Epistêmico é conhecido por alegar oferecer a melhor resposta para alguns dos principais problemas epistemológicos, dentre eles o problema gerado pelos paradoxos céticos e, por conseguinte, por deter o conhecimento sobre muitas coisas que ordinariamente julgávamos já conhecidas. Da mesma forma, seria uma via capaz de manter a validade do princípio de fechamento dedutivo. O presente texto pretende analisar a teoria contextualista, conforme apresentada por Stewart Cohen, mostrando como o contextualismo resolve essas questões. Na primeira parte do (...) texto apresentaremos alguns problemas (e algumas características históricas) que culminaram no surgimento do contextualismo. Na segunda parte explanaremos a teoria contextualista de Cohen. Em seguida levantamos algumas objeções comumente endereçadas ao contextualismo. Por fim, concluímos que, embora não seja completamente refutada, a teoria contextualista deve dirimir dúvidas e explicar algumas dificuldades para manter a sua plausibilidade. Palavras-Chave: Contextualismo; Ceticismo; Conhecimento; Stewart Cohen. -/- Abstract Epistemic Contextualism is known by his allegation to possess the best answer to some of the major epistemological problems, among them, the problem created by the skeptical paradoxes and therefore the claim that we can know many things we ordinarily claim to know, and also maintains the validity of the closure principle. This paper seeks to examine Contextualism, as presented by Stewart Cohen, showing how Contextualism solves these problems. In the first section of the text I will present some problems (and some historic features) that originated Contextualism. In the second section I will present the Cohen`s Contextualism. Then, we consider some objections raised against the contextualista theory. Finally, we conclude that although these objections are not able to completely refute contextualism its proponents have to give better explanations in order to maintain its plausibility.

The main argument given for relevant alternatives theories of knowledge has been that they answer scepticism about the external world. I will argue that relevant alternatives also solve two other problems that have been much discussed in recent years, a) the bootstrapping problem and b) the apparent conflict between semantic externalism and armchair self-knowledge. Furthermore, I will argue that scepticism and Mooreanism can be embedded within the relevant alternatives framework.

Keith DeRose’s solution to the skeptical problem is based on his indirect sensitivity account. Sensitivity is not a necessary condition for any kind of knowledge, as direct sensitivity accounts claim, but the insensitivity of our beliefs that the skeptical hypotheses are false explains why we tend to judge that we do not know them. The orthodox objection line against any kind of sensitivity account of knowledge is to present instances of insensitive beliefs that we still judge to constitute knowledge. This (...) objection line offers counter-examples against the claim of direct sensitivity accounts that sensitivity is necessary for any kind of knowledge. These examples raise an easy problem for indirect sensitivity accounts that claim that there is only a tendency to judge that insensitive beliefs do not constitute knowledge, which still applies to our beliefs that the skeptical hypotheses are false. However, a careful analysis reveals that some of our beliefs that the skeptical hypotheses are false are sensitive; nevertheless, we still judge that we do not know them. Therefore, the fact that some of our beliefs that the skeptical hypotheses are false are insensitive cannot explain why we tend to judge that we do not know them. Hence, indirect sensitivity accounts cannot fulfill their purpose of explaining our intuitions about skepticism. This is the hard problem for indirect sensitivity accounts. (shrink)

According to Agrippa's trilemma, an attempt to justify something leads to either infinite regress, circularity, or dogmatism. This essay examines whether and to what extent the trilemma applies to ethics. There are various responses to the trilemma, such as foundationalism, coherentism, contextualism, infinitism, and German idealism. Examining those responses, the essay shows that the trilemma applies at least to rational justification of contentful moral beliefs. This means that rationalist ethics based on any contentful moral belief are rationally unjustifiable.

According to an influential contextualist solution to skepticism advanced by Keith DeRose, denials of skeptical hypotheses are, in most contexts, strong yet insensitive. The strength of such denials allows for knowledge of them, thus undermining skepticism, while the insensitivity of such denials explains our intuition that we do not know them. In this paper we argue that, under some well-motivated conditions, a negated skeptical hypothesis is strong only if it is sensitive. We also consider how a natural response on behalf (...) of DeRose appears to be equally available to his primary rival (viz., the sensitivity theorist). (shrink)

In this paper I develop a version of contextualism that I call interests contextualism. Interests contextualism is the view that the truth-conditions of knowledge ascribing and denying sentences are partly determined by the ascriber’s interests and purposes. It therefore stands in opposition to the usual view on which the truth-conditions are partly determined by the ascriber’s conversational context. I give an argument against one particular implementation of the usual view, differentiate interests contextualism from other prominent versions of contextualism and argue (...) that, unlike those versions, interests contextualism can mitigate against the epistemic descent objection put forward by Duncan Pritchard in his ‘Contextualism, Scepticism, and the Problem of Epistemic Descent’ (the objection is that, on the contextualist view, an ascriber of knowledge cannot, for some subject S and proposition p, properly ascribe knowledge that p to S if that ascriber has previously retracted an earlier ascription of knowledge that p to S).

In this essay I show how to reconcile epistemic invariantism with the knowledge account of assertion. My basic proposal is that we can comfortably combine invariantism with the knowledge account of assertion by endorsing contextualism about speech acts. My demonstration takes place against the backdrop of recent contextualist attempts to usurp the knowledge account of assertion, most notably Keith DeRose's influential argument that the knowledge account of assertion spells doom for invariantism and enables contextualism's ascendancy.

The paper discusses approaches to Epistemic Contextualism that model the satisfaction of the predicate ‘know’ in a given context C in terms of the notion of belief/fact-matching throughout a contextually specified similarity sphere of worlds that is centred on actuality. The paper offers three counterexamples to approaches of this type and argues that they lead to insurmountable difficulties. I conclude that what contextualists (and Subject-Sensitive Invariantists) have traditionally called the ‘epistemic standards’ of a given context C cannot be explicated in (...) terms of a contextually specified similarity sphere that is centred on actuality. The mentioned accounts of epistemic relevance and thus the corresponding accounts of the context-sensitivity (or subject-sensitivity) of ‘knows’ are to be rejected. (shrink)

Title in English: : A Contextualist Answer to Agrippa's Argument.

In this paper, I explore Bach’s idea (Bach, 2000) that null appositives, intended as expanded qua-clauses, can resolve the puzzles of belief reports. These puzzles are crucial in understanding the semantics and pragmatics of belief reports and are presented in a section. I propose that Bach’s strategy is not only a way of dealing with puzzles, but also an ideal way of dealing with belief reports. I argue that even simple unproblematic cases of belief reports are cases of pragmatic intrusion, (...) involving null appositives, or to use the words of Bach, ‘qua-clauses’. The main difference between my pragmatic approach and the one by Salmon (1986) is that this author uses the notion of conversational implicature, whereas I use the notion of pragmatic intrusion and explicature. From my point of view, statements such as ‘‘John believes that Cicero is clever’’ and ‘‘John believes that Tully is clever’’ have got distinct truth-values. In other words, I claim that belief reports in the default case illuminate the hearer on the mental life of the believer, that includes specific modes of presentation of the referents talked about. Furthermore, while in the other pragmatic approaches, it is mysterious how a mode of presentation is assumed to be the main filter of the believer’s mental life, here I provide an explanatory account in terms of relevance, cognitive effects, and processing efforts. The most important part of the paper is devoted to showing that null appositives are required, in the case of belief reports, to explain certain anaphoric effects, which would otherwise be mysterious. My examples show that null appositives are not necessitated at logical form, but only at the level of the explicature, in line with the standard assumptions by Carston and Recanati on pragmatic intrusion. I develop a potentially useful analysis of belief reports by exploiting syntactic and semantic considerations on presuppositional clitics in Romance. (shrink)

Epistemic contextualism (EC) is primarily a semantic view, viz. the view that ‘knowledge’-ascriptions can change their contents with the conversational context. To be more precise, EC is the view that the predicate ‘know’ has an unstable Kaplan character, i.e. a character that does not map all contexts on the same content. According to EC, ‘know’ is thus an indexical expression. Notwithstanding this purely linguistic characterisation of EC, contextualists have traditionally argued that their views have considerable philosophical impact, this being due (...) to the alleged fact that their linguistic views about ‘know’ provide the resources for a resolution of sceptical puzzles. In this paper I will address an objection to EC claiming that, as a linguistic view about the term ‘know’, EC cannot be of any epistemological significance. (shrink)

Empirical knowledge exists in the form of antiskeptical conditionals, which are propositions like [if I am not undetectably deceived, then I am holding a pen]. Such conditionals, despite their trivial appearance, have the same essential content as the categorical propositions that we usually discuss, and can serve the same functions in science and practical reasoning. This paper sketches out two versions of a general response to skepticism that employs these conditionals. The first says that our ordinary knowledge attributions can safely (...) be replaced by statements using antiskeptical conditionals, which provides a way around the standard sort of skeptical argument while accepting its soundness with respect to the usual targets. The second analyzes the objects of our ordinary knowledge attributions as antiskeptical conditionals, which allows us to refute, not just evade, the skeptic's argument. Both versions compare favorably to the best-knowncurrent approaches to skepticism, including semantic contextualism. (shrink)

This article offers a novel sceptical argument that the sensitivity-contextualist must say is sound; moreover, she must say that the conclusion of thisargument is true at ordinary standards. The view under scrutiny has it that in different contexts knowledge-attributing sentences express different propositions, propositions which differ in the stretch of worlds across which the subject is required to track the truth. I identify the underlying reason for the sceptical result and argue that it makes sensitivity-contextualism irremediably flawed. Contextualists, I conclude, (...) should abandon sensitivity for some other piece of epistemic machinery.Cet article présente un nouvel argument en faveur du scepticisme que les tenants du contextualisme sensoriel doivent reconnaître comme valide; qui plus est, ils doivent admettre que les conclusions de cet argument sont vraies selon des critères standards. J’examine la position selon laquelle, dans différents contextes, les formules visant à désigner un contenu de connaissance expriment différentespropositions, propositions qui diffèrent les unes des autres dans la série des mondes au sein desquels le sujet est à la recherche de la vérité. J’identifie la raison sur laquelle se fonde le constat sceptique et soutient qu’il fait du contextualisme sensoriel une position irrémédiablement défaillante. Je conclue en proposant que les tenants de cette position devraient abandonner la sensation à la faveur d’autres composantes des rouages épistémiques. (shrink)

The Matrix exposes us to the uncomfortable worries of philosophical skepticism in an especially compelling way. However, with a bit more reflection, we can see why we need not share the skeptic’s doubts about the existence of the world. Such doubts are appropriate only in the very special context of the philosophical seminar. When we return to normal life we see immediately that they are groundless. Furthermore, we see also the drastic mistake that Cypher commits in turning his back upon (...) reality and re-entering the matrix. Not only does reason compel us to admit the existence of the external world, it also requires us to face this world, to build for ourselves meaningful lives within it, and to engage, as adults, in the serious business of living.
