I argue for the Wittgensteinian thesis that mathematical statements are expressions of norms, rather than descriptions of the world. An expression of a norm is a statement like a promise or a New Year's resolution, which says that someone is committed or entitled to a certain line of action. A expression of a norm is not a mere description of a regularity of human behavior, nor is it merely a descriptive statement which happens to entail a norms. The view can (...) be thought of as a sort of logicism for the logical expressivist---a person who believes that the purpose of logical language is to make explicit commitments and entitlements that are implicit in ordinary practice. The thesis that mathematical statements are expression of norms is a kind of logicism, not because it says that mathematics can be reduced to logic, but because it says that mathematical statements play the same role as logical statements. ;I contrast my position with two sets of views, an empiricist view, which says that mathematical knowledge is acquired and justified through experience, and a cluster of nativist and apriorist views, which say that mathematical knowledge is either hardwired into the human brain, or justified a priori, or both. To develop the empiricist view, I look at the work of Kitcher and Mill, arguing that although their ideas can withstand the criticisms brought against empiricism by Frege and others, they cannot reply to a version of the critique brought by Wittgenstein in the Remarks on the Foundations of Mathematics. To develop the nativist and apriorist views, I look at the work of contemporary developmental psychologists, like Gelman and Gallistel and Karen Wynn, as well as the work of philosophers who advocate the existence of a mathematical intuition, such as Kant, Husserl, and Parsons. After clarifying the definitions of "innate" and "a priori," I argue that the mechanisms proposed by the nativists cannot bring knowledge, and the existence of the mechanisms proposed by the apriorists is not supported by the arguments they give.

La tesis de la privacidad linguitica nace con el gesto fundador de la filosofía moderna que apoya toda legitimidad en la subjetividad y la conciencia. Ello da origen a dos problemas filos�ficos fundamentales, concernientes al mundo y al solipsismo. El siglo XX creyó encontrar en el lenguaje una salida a estos problemas. Wittgenstein es allí una pieza clave. Sin embargo las interpretaciones más influyentes de Wittgenstein enfocaron la crítica del lenguaje privado de tal modo que la salida debía permanecer en (...) el terreno epistemológico de las garantías o criterio de corrección (Malcolm, Fogelin, Kenny, Canfield, Tugendhat). Sostenemos que la interpretación propuesta por Kripke se apoya un un agudo diagnóstico de la fuente de estas dificultades, dándose cuenta que la refutación del lenguaje privado requería abandonar toda una concepción, la del realismo, que afectaban por igual al lenguaje privado y al público. Su argumentación, centrada en la semántica, irradia consecuencias más allá de la misma. Su "solución escéptica" al establecer que los juicios de corrección, entendidos como básicos y primitivos, sólo poseen sentido en el marco de una comunidad uniforme en sus juicios, coloca al discurso filosófico en un nuevo terreno.

Engaging with the question of the extent to which the so-called human, economic or social sciences are actually sciences, this book moves away from the search for a criterion or definition that will allow us to sharply distinguish the scientific from the non-scientific. Instead, the book favours the pursuit of clarity with regard to the various enterprises undertaken by human beings, with a view to dissolving the felt need for such a demarcation. In other words, Read pursues a ‘therapeutic’ approach (...) to the issue of the status and nature of these subjects. Discussing the work of Kuhn, Winch and Wittgenstein in relation to fundamental question of methodology, Wittgenstein among the Sciences undertakes an examination of the nature of (natural) science itself, in the light of which a series of successive cases of putatively scientific disciplines are analysed. A novel and significant contribution to social science methodology and the philosophy of science and ‘the human sciences’, this book will be of interest to social scientists and philosophers, as well as to psychiatrists, economists and cognitive scientists.

Against a broad consensus within contemporary analytic philosophy, Hattiangadi (Mind and Language 21(2):220–240, 2006 , 2007 ) has recently argued that linguistic meaning is not normative, at least not in the sense of being prescriptive. She maintains, more specifically, that standard claims to the effect that meaning is normative are usually ambiguous between two readings: one, which she calls Prescriptivity , and another, which she calls Correctness . According to Hattiangadi, though meaning is normative in the uncontroversial sense specified in (...) the principle Correctness , it is not normative in the sense specified by Prescriptivity . In this paper, I instead show that meaning is normative in the sense of being prescriptive. My argument for this claim takes the form of a classical disjunctive syllogism. I argue that either Correctness implies (because it presupposes) Prescriptivity , or linguistically meaningful items are ‘intrinsically intentional.’ But linguistically meaningful items are not intrinsically intentional, and thus Correctness implies (because it presupposes) Prescriptivity.

Except for a patina of twenty-first century modernity, in the form of logic and language, philosophy is exactly the same now as it ever was; it has made no progress whatsoever. We philosophers wrestle with the exact same problems the Pre-Socratics wrestled with. Even more outrageous than this claim, though, is the blatant denial of its obvious truth by many practicing philosophers. The No-Progress view is explored and argued for here. Its denial is diagnosed as a form of anosognosia, a (...) mental condition where the affected person denies there is any problem. The theories of two eminent philosophers supporting the No-Progress view are also examined. The final section offers an explanation for philosophy 's inability to solve any philosophical problem, ever. The paper closes with some reflections on philosophy 's future. (shrink)

It is sometimes objected that anti-individualism, because of its assumption of the constitutive role of natural and social environments in the individuation of intentional attitudes, raises sceptical worries about first-person authority--that peculiar privilege each of us is thought to enjoy with respect to non-Socratic self-knowledge. Gary Ebbs believes that this sort of objection can be circumvented, if we give up metaphysical realism and scientific naturalism and adopt what he calls a “participant perspective” on our linguistic practices. Drawing on broadly Wittgensteinian (...) considerations, I argue that Ebbs is right about this, and I show how two likely objections to his view can be circumvented. I also argue that mere adoption of the participant perspective does not serve to refute external-world sceptic. (shrink)

In developing an "internal" sociology of science, the sociology of scientific knowledge drew on Wittgenstein’s later philosophy to reinterpret traditional epistemological topics in sociological terms. By construing scientific reasoning as rule following within a collective, sociologists David Bloor and Harry Collins effectively blocked outside criticism of a scientific field, whether scientific, philosophical, or political. Ethnomethodologist Michael Lynch developed an alternative, Wittgensteinian reading that similarly blocked philosophical or political critique, while also disallowing analytical appeals to historical or institutional contexts. I criticize (...) these Wittgensteinian sociologies and argue for the historical and contemporary significance of methodological criticisms of scientific practice that conjoin epistemological and political categories. I consider two such cases briefly: the Baconian criticism of Scholastic science in the early Royal Society and the criticism of AIDS drug testing protocols by activists. Key Words: Wittgenstein • sociology of scientific knowledge • ethnomethodology • scientific method • interpretive sociology. (shrink)

In this paper I argue that the most prominent and familiar features of Wittgenstein’s rule following considerations generate a powerful argument for the thesis that most of our concepts are innate, an argument that echoes a Chomskyan poverty of the stimulus argument. This argument has a significance over and above what it tells us about Wittgenstein’s implicit commitments. For, it puts considerable pressure on widely held contemporary views of concept learning, such as the view that we learn concepts by constructing (...) prototypes. This should lead us to abandon our general default hostility to concept nativism and be much more sceptical of claims made on behalf of learning theories. (shrink)

Many people claim that semantic content is normative, and that therefore naturalistic theories of content face a potentially insuperable difficulty. The normativity of content allegedly undermines naturalism by introducing a gap between semantic 'ought's and the explanatory resources of naturalism. I argue here that this problem is not ultimately pressing for naturalists. The normativity thesis, I maintain, is ambiguous; it could mean either that the content of a term prescribes a pattern of use, or that it merely determines which pattern (...) of use can be described as 'correct'. For the antinaturalist argument to go forward, content must be prescriptive. I argue, however, that it is not. Moreover, the thesis that content supplies standards for correct use is insufficient to supply a similar, a priori objection to naturalism. (shrink)

An attempt is made to answer the question why wittgenstein might have found the analogy between speaking and playing games philosophically exciting. It is argued that on the face of it the two are strikingly disanalogous, But that on reflecting further one can find various features of games (9 are distinguished in all) which are also features of some speech episodes, And the awareness of which could be philosophically significant.

In this paper, I will argue against certain criticisms of Kripke’s Wittgenstein’s sceptical argument and sceptical solution, made especially by Baker and Hacker, McGinn, and McDowell. I will show that their interpretation of Kripke’s Wittgenstein’s view is misplaced. According to Kripke’s Wittgenstein’s sceptical argument, there is no fact as to what someone means by her words. For Kripke, this conclusion, combined with Classical Realist view of meaning, leads to the Wittgensteinian paradox, according to which there is no such thing as (...) meaning anything by any word. Wittgenstein presents this paradox in paragraph 201 of the Philosophical Investigations. As Kripke reads Wittgenstein, Wittgenstein is in agreement with his sceptic on the sceptical conclusion of the sceptical argument, that is, that there is no fact about meaning, and builds his sceptical solution on an endorsement of that. McDowell, McGinn, and others have objected that Kripke has failed to properly understand Wittgenstein’s main remarks in 201, that is, that the paradox is the result of a misunderstanding of the ordinary notion of meaning. Wittgenstein does not accept such a sceptical conclusion. I will use the distinction George Wilson draws between two different conclusions of the sceptical argument and show that Kripke has respected all of the remarks that Wittgenstein has put in section 201.

Wittgenstein harshly criticized what he considered “mythologies” infecting our understanding of how mathematics work. He was especially reluctant to the idea that they describe a realm of abstract entities influencing our cognitive capacities. Several Wittgenstein scholars have drawn the conclusion that his analysis results in a sociological interpretation of mathematics. The present paper aims at demonstrating that although mathematical practices deserve to be called “social” this doesn’t necessarily leads us to the conclusion that they are offered to sociological explanation.

Esta enciclopédia abrange, de uma forma introdutória mas desejavelmente rigorosa, uma diversidade de conceitos, temas, problemas, argumentos e teorias localizados numa área relativamente recente de estudos, os quais tem sido habitual qualificar como «estudos lógico-filosóficos». De uma forma apropriadamente genérica, e apesar de o território teórico abrangido ser extenso e de contornos por vezes difusos, podemos dizer que na área se investiga um conjunto de questões fundamentais acerca da natureza da linguagem, da mente, da cognição e do raciocínio humanos, bem (...) como questões acerca das conexões destes com a realidade não mental e extralinguística. A razão daquela qualificação é a seguinte: por um lado, a investigação em questão é qualificada como filosófica em virtude do elevado grau de generalidade e abstracção das questões examinadas (entre outras coisas); por outro, a investigação é qualificada como lógica em virtude de ser uma investigação logicamente disciplinada, no sentido de nela se fazer um uso intenso de conceitos, técnicas e métodos provenientes da disciplina de lógica. O agregado de tópicos que constitui a área de estudos lógico-filosóficos é já visível, pelo menos em parte, no Tractatus Logico-Philosophicus de Ludwig Wittgenstein, uma obra publicada em 1921. E uma boa maneira de ter uma ideia sinóptica do território disciplinar abrangido por esta enciclopédia, ou pelo menos de uma porção substancial dele, é extrair do Tractatus uma lista dos tópicos mais salientes aí discutidos; a lista incluirá certamente tópicos do seguinte género, muitos dos quais se podem encontrar ao longo desta enciclopédia: factos e estados de coisas; objectos; representação; crenças e estados mentais; pensamentos; a proposição; nomes próprios; valores de verdade e bivalência; quantificação; funções de verdade; verdade lógica; identidade; tautologia; o raciocínio matemático; a natureza da inferência; o cepticismo e o solipsismo; a indução; as constantes lógicas; a negação; a forma lógica; as leis da ciência; o número.

RésuméPaul Boghossian soutient contre Wittgenstein que le normativisme au sujet de la logique et des mathématiques est incompatible avec le fait de tenir les énoncés logiques et mathématiques pour vrais et que le normativisme entraîne une régression indue. Je soutiens, pour ma part, que le normativisme n'entraîne pas une telle régression, parce que les normes peuvent être implicites et que le normativisme peut bien être «factualiste» si l'on rejette ce que Rockney Jacobsen appelle le «cognitivisme sémantique». Je tiens en outre (...) que la position de Boghossian repose sur la façon trompeuse dont il découpe le terrain conceptuel. (shrink)

Speech Acts, Criteria and Intentions What makes a speech act a speech act? Which are its necessary and sufficient conditions? I claim in this paper that we cannot find an answer to those questions in Austin's doctrine of the infelicities, since some infelicities take place in fully committing speech acts, whereas others prevent the utterance from being considered as a speech act at all. With this qualification in mind, I argue against the idea that intentions—considered as mental states accomplishing a (...) causal role in the performance of the act—should be considered among the necessary conditions of speech acts. I would thus like to deny a merely ‘symptomatic’ account of intentions, according to which we could never make anything but fallible hypotheses about the effective occurrence of any speech act. I propose an alternative ‘criterial’ account of the role of intentions in speech acts theory, and analyse Austin's and Searle's approaches in the light of this Wittgensteinian concept. Whether we consider, with Austin, that speech acts ‘imply’ mental states or, with Searle, that they ‘express’ them, we could only make sense of this idea if we considered utterances as criteria for intentions, and not as alleged behavioural effects of hidden mental causes.

Explores the stable core of Wittgenstein's philosophy as developed from the Tractatus to the Philosophical Investigations.

Famously, Kripke has argued that the central portion of the Philosophical Investigations describes both a skeptical paradox and its skeptical solution. Solving the paradox involves the element of the community, which determines correctness conditions for rule-following behavior. What do such conditions precisely consist of? Is it accurate to say that there is no fact to the matter of rule following? How are the correctness conditions sustained in the community? My answers to these questions revolve around the idea that a rule (...) is followed insofar as a convention is in place. In particular, I consider the game-theoretic definition of convention offered by David Lewis and I show that it illuminates essential aspects of the communitarian understanding of rule-following. Make the following experiment: say “It’s cold here” and mean “It’s warm here”. Can you do it?Ludwig Wittgenstein, Philosophical Investigations, 1953, §510.I can’t say “it’s cold here” and mean “it’s warm here”—at least, not without a little help from my friends.David Lewis, Convention.

L'A. défend la thèse selon laquelle Wittgenstein développe une conception pragmatique et linguistique des relations internes qui définissent les vérités nécessaires: 1) qui n'implique pas l'analyticité de toutes les propositions exprimant des relations internes, 2) qui établit une distinction entre l'analytique et le synthétique, 3) qui s'avère compatible avec la critique de l'analyticité entreprise par Quine.

The interactivist approach to development generates a framework of types of constraints on what can be constructed. The four constraint types are based on: (1) what the constructed systems are about; (2) the representational relationship itself; (3) the nature of the systems being constructed; and (4) the process of construction itself. We give illustrations of each constraint type. Any developmental theory needs to acknowledge all four types of constraint; however, some current theories conflate different types of constraint, or rely on (...) a single constraint type to explicate development. Such theories will be inherently unable to explain important aspects of development. (shrink)

Phenomena such as our “understanding in a flash” and our immediate knowledge of the meaning of our own utterances seem to point to problems that call for philosophical explanation. Even though the meaning of an utterance appears to depend on where and when we use it, on what we use it for and on what we expect in response, we do not examine such circumstances when asked what we mean. Instead we simply say what we mean. Similarly, our having grasped (...) a rule is something shown by how we perform certain tasks and respond to certain requests. But we frequently declare that we have indeed grasped a rule without paying any attention to those overt performances and, despite this, we are normally correct. These facts seem puzzling and impel us towards a certain philosophical picture of meaning and understanding. This picture identifies the meaning of a subject’s utterances, and his understanding of the rules that he follows, with some kind of structure of which he has immediate knowledge. By virtue of their connection with these private, meaning-constituting phenomena, the public manifestations of meaning and understanding are invaluable as clues to the meaning of an utterance or a subject’s understanding of a rule. But the latter are, nevertheless, ultimately fixed by the inner structures to which only the subject in question has immediate access and upon which he or she therefore has authority. This picture prompts a host of perplexing questions. “What are these immediately-knowable structures?” “What does it mean to say that we have immediate acquaintance with them?” “How are these private structures connected with those public performances?” These questions are notoriously difficult to answer.

This paper investigates the relation between what James Conant has called Kantian and Cartesian varieties of skepticism. It is argued that a solution to the most prominent example of a Kantian variety of skepticism, i.e. Kripkensteinian skepticism about rule-following and meaning, can be found in the works of Wilfrid Sellars. It is then argued that, on the basis of that very same solution to the Kantian problematic of rule-following and meaning, a novel argument against external world skepticism can be formulated. (...) This argument takes the shape of a transcendental argument, which is reminiscent of Hilary Putnam’s infamous argument against the brain-in-a-vat hypothesis, but is, as is argued, superior to it in certain respects.

It is widely thought that, in §201 of the Philosophical Investigations, Wittgenstein reveals himself to oppose a definite view or theory of rule-following. I argue that, due to the self-undermining character of that section, no such interpretation should be accepted. Then I sketch a reading of Wittgenstein’s method that accounts for the paradoxical nature of §201, and I show how this methodology is realized in his remarks on following a rule.

The main aim of this article is to pose and consider the following question: Does the reasoning that led to Kripkenstein’s sceptical paradox undermine all versions of materialism, including nonreductive materialism? First, I present other versions of materialism in the philosophy of mind. Then I point out that, according to nonreductive materialists, one can neither define mental properties in terms of physical properties nor derive psycho‑physical laws from the laws of physics. The presently‑understood thesis of materialism is confined by the (...) following claim: the same distribution of physical properties entails the same distribution of mental properties. In other words, the mental properties supervene upon physical properties. This account then leads to the following formulation of the main question: Assuming that Kripkenstein is right, do mental properties supervene upon physical properties? Taking into account that answering this question requires a discussion of the notions of supervenience and Kripkenstein’s paradox, I devote two parts of my paper to these topics. The conclusion which I reach is as follows: If the reasoning that led to Kripkenstein’s paradox is correct, mental properties can only globally supervene upon physical properties, and consequently no version of materialism can be empirically justified.

In this essay, I seek to demonstrate the interplay of philosophical voices – particularly, that of a platonist voice and a community-agreement-view voice – that drives Wittgenstein’s rule-following dialectic forward; and I argue that each voice succumbs to a particular form of dialectical oscillation that renders its response to the problem of rule-following philosophically inadequate. Finally, I suggest that, by seeing and taking stock of the dilemma in which these responses to the skeptical problem are caught, we can come to (...) appreciate Wittgenstein’s own view of what might constitute a proper a response to the so-called problem of rule-following. This view can be preliminarily characterized by saying that Wittgenstein’s aim is to dissolve the temptation to philosophically rebut the skeptical challenge posed by the rule-following dialectic, an aim he achieves by revealing the semantic emptiness of the apparent sentences that raise the skeptical problem.

This paper tries to read some structure into the perplexing diversity of the literature on Heidegger ’s concept of authenticity. It argues that many of the interpretations available rely on views that are false and cannot be Heidegger ’s. It also shows that the only correct interpretation of Heidegger ’s concept of authenticity emerges from a synthesis of Dreyfus ’ later interpretation and Haugeland’s interpretation of this concept. A synthesis of these interpretations yields an interpretation, according to which Dasein’s being (...) is authentic only if it is capable of using tools or language in radically new ways. (shrink)

Abstract This paper discusses the semantic theory presented in Robert Brandom’s Making It Explicit . I argue that it is best understood as a special version of dynamic semantics, so that these semantics by themselves offer an interesting theoretical alternative to more standard truth-conditional theories. This reorientation also has implications for more foundational issues. I argue that it gives us the resources for a renewed argument for the normativity of meaning. The paper ends by critically assessing the view in both (...) its development and motivations.

Two readings of Wittgenstein's rule-following paradox dominate the literature: either his arguments lead to skepticism, and thus to the view that only a deflated account of meaning is available, or they lead to quietism, and thus to the view that no philosophical account of meaning is called for. I argue, against both these positions, that a proper diagnosis of the paradox points the way towards a constructive, non-sceptical account of meaning.

Wittgenstein characterises ‘necessary truths’ as rules of representation that do not answer to reality. The invocation of rules of representation has led many to compare his work with Kant's. This comparison is illuminating, but it can also be misleading. Some go as far as casting Wittgenstein's later philosophy as a specie of transcendental idealism, an interpretation that continues to gather support despite scholars pointing to its limitations. To understand the temptation of this interpretation, attention must be paid to a distinction (...) Bernard Williams (1981) makes, echoing Kant, between empirical and transcendental idealism. Williams claims that the move to transcendental idealism is an effort to block empirical idealism. The latter, in this context, amounts to a scepticism regarding necessity and a denial of its objectivity. To show what is wrong with the transcendental interpretation, it is important to challenge the mistaken presumption that Wittgenstein's philosophy would otherwise lead to empirical idealism. The fundamental mistake common to both attributions is that they misunderstand the relation that obtains between our rules of representation and the contingent facts that condition those rules of representation. Once this relation has been clarified, Wittgenstein's philosophy can be understood as providing a genuine alternative to realism and idealism. (shrink)

This paper deals with Wittgenstein’s rule-following paradox, focussing on the infinite rule-regress as featured in Kripke’s Wittgenstein on Rules and Private Language. I argue that one of the most salient and popular proposed solutions (championed by John McDowell), which argues that rule-following is grounded in “custom,” “practice” or “form of life, remains unsatisfactory because part of this proposal is the rejection of further “theory” (commonly attributed to Wittgenstein) which seemingly makes it impossible to substantiate the claim of how customs, practices (...) or forms of life ground rule-following. I argue that this conundrum can be solved by introducing Wilhelm Dilthey’s overlooked notion of objective spirit as the objectivated sediment of historical human communality. This proposal allows us to substantiate Wittgenstein’s hints at the connection between rule-following and customs, practices, and forms of life without introducing “problematic theories.” Combining Wittgenstein’s views with Dilthey’s notion of objective spirit results in a solution that is neither skeptical nor straight, but therapeutic.

We are living in an increasingly complex world. How are we able to cope with this complexity and the difficulties that arise from it? Can philosophy and art, classified as the two utmost useless and pointless disciplines, have any (positive) influence on the urgent and pressing problems at hand? And, related to this, if the two have more than just their uselessness in common, how, then, are philosophy and art related? In this article, I will argue that although ‘useless’ disciplines (...) such as philosophy and art have no direct influence on our complex world, they are nonetheless the most important ones, because those working within them practice their insights in an indirect way. Indirect influence may take a little longer, but the impact is much stronger, affecting our thinking and our attitudes from within, as it were. This indirect approach has everything to do with the sort of questions philosophers and artists occupy themselves with. I will show how both address, albeit each in their own way, fundamental questions, and thereby make use of thought experiments. Intuition and imagination play a decisive part in the creative processes that are involved in thought experiments and thinking. It is argued that we all are able to learn a ‘delayed unconscious thinking’ that leads to an artistic attitude; one that will activate an artistic turn. (shrink)

ABSTRACTWittgenstein’s remark that one cannot follow a rule only once has generated two puzzles: how can everyone accept it to be true? and why does Wittgenstein advance it? These two puzzles have tormented commentators for decades. In this paper I put forward a new interpretation and explain away the two puzzles. I shall show that Wittgenstein’s remark is plain truth and that his motivation behind making it is to dissolve the picture theory of meaning propounded in the Tractatus. This interpretation (...) also helps us to see that Wittgenstein’s other remark, that to follow a rule is a custom, is also a grammatical one. (shrink)

Taking its orientation from Peter Winch, this article critiques from a Wittgensteinian point of view some “theoreticist” tendencies within constructivism. At the heart of constructivism is the deeply Wittgensteinian idea that the world as we know and understand it is the product of human intelligence and interests. The usefulness of this idea can be vitiated by a failure to distinguish conceptual from empirical questions. I argue that such a failure characterises two influential constructivist theories, those of Ernst von Glasersfeld and (...) David Bloor. These are considered in turn. Both theories seek to give a general, causal account of knowledge: von Glasersfeld's in term of cognitive subjectivity, Bloor's in terms of social agreement. Ironically, given that both writers cite Wittgenstein as a source of theoretical inspiration, assumptions of both theories run counter to key Wittgensteinian arguments. To show that Wittgenstein's views offer no solace to the realist, the article closes with a brief consideration of John Searle's theory of knowledge. (shrink)

PRESCRIPTIVE EXPLICATION OF THE NORMATIVITY OF MEANING THESIS The aim of this paper is to analyse prescriptive interpretations of the thesis that meaning is normative, which was introduced by Saul Kripke and later developed by Paul Boghossian. We are going to show that meaning prescriptivism is counter-intuitive and has implausible consequences. Attempts to save prescriptive interpretations by appealing to prima facie obligations or „normativity of judgment” are unsuccessful.

This paper aims to motivate a scepticism about scepticism in contemporary epistemology. I present the sceptic with a dilemma: On one parsing of the BIV (brain-in-a-vat) scenario, the second premise in a closure-based sceptical argument will turn out false, because the scenario is refutable; on another parsing, the scenario collapses into incoherence, because the sceptic cannot even save the appearances. I discuss three different ways of cashing out the BIV scenario: ‘Recent Envatment’ (RE), ‘Lifelong Envatment’ (LE) and ‘Nothing But Envatment’ (...) (NBE). I show that RE scenarios are a kind of ‘local’ sceptical scenario that does not pose a significant threat to the possibility of perceptual knowledge as such. I then go on to consider the more radical (or global) LE and NBE scenarios, which do undermine the possibility of perceptual knowledge of an ‘external’ world by positing that it is conceivable that one has always been envatted and, hence, trapped in a ‘global’ illusion. I start by assuming that we could be in such a scenario (LE or NBE) and then spell out what we would need to presuppose for such scenarios to be capable of being actual. Drawing on some central insights from Wittgenstein’s anti-private language considerations, I show that the truth of a global scepticism would presuppose the possibility of a private ‘vat-language’, a notion that cannot be rendered coherent. But, if so, then neither can the sceptical scenarios that presuppose such a conception. (shrink)
