Abstract Relativism about knowledge attributions is the view that a single occurrence of ‘S knows [does not know] that p’ may be true as assessed in one context and false as assessed in another context. It has been argued that relativism is equipped to accommodate all the data from speakers’ use of ‘know’ without recourse to an error theory. This is supposed to be relativism’s main advantage over contextualist and invariantist views. This paper argues that relativism does require the attribution (...) of semantic blindness to speakers, viz. to account for sceptical paradoxes and epistemic closure puzzles. To that end, the notion of semantic blindness is clarified by distinguishing between content-blindness and index-blindness, and it is argued that the attribution of index-blindness required by the relativist account is implausible. Along the way, it is shown that error-theoretic objections from speakers’ inter-contextual judgments fail against relativism.

In the present article, I attempt to relate Saul Kripke's “sceptical paradox” to some issues about the self; specifically, the relation between the self and its mental states and episodes. I start with a brief reconstruction of the paradox, and venture to argue that it relies crucially on a Cartesian model of the self: the sceptic regards the Wittgensteinian “infinite regress of interpretation” as the foundation of his challenge, and this is where he commits the crucial mistake. (...) After the diagnosis, I attempt to sketch my own model of the self and its mental states and episodes. This tentative picture binds meaning and the self together, stressing the subjective aspect of meaning without committing the same fallacy. The solution ventured here is relatively independent of the secondary literatures on the sceptical paradox of following rules, for it aims to provide a new angle to understand and meet the challenge presented by the sceptic.

In this dissertation I examine the sceptical problem of rule following presented by Saul Kripke in his interpretation of Ludwig Wittgenstein's later works: Do any facts determine what rule we were following in our apparently rule-following activities such as the use of language? I distinguish three ways of understanding this question--modest scepticism, radical scepticism, and metascepticism--and address them in Parts 1, 2 and 3 of the dissertation, respectively. ;Part 1 discusses modest scepticism, which asserts that no finite facts about (...) humans can determine rules which have infinitely many possible applications. I resolve this apparent conflict between the finite and the infinite by incorporating the recursiveness of rule applications into the theory of rules. ;Part 2 discusses radical scepticism, which asserts that no facts determine what normative rules we were following. I show first that this challenge has a wider scope than the Humean Thesis of the underivability of ought from is, and that as a result, the radical sceptic can refute attitudinal theories of norms, which have been considered a possible response to the Humean challenge. I then propose a solution to radical scepticism which explains our practice and beliefs about normative rules without assuming the existence of rule-determining facts. Unlike the solution Kripke ascribes to Wittgenstein, it offers no justification of our practice and beliefs about normative rules. Some methodological implications of the solution are also explored. ;Part 3 discusses metascepticism about rule following, whose challenge extends to the rules used for the very discussion of rule following. I examine first whether such a challenge is self-undermining in that it makes the sceptical argument itself impossible. I propose an extended form of reductio ad absurdum argument by which the metasceptic can challenge rules in general, including those used in the sceptical argument. Then I argue that the solution to radical scepticism given in Part 2 survives metascepticism as well. (shrink)

The sceptic about the external world presents us with a paradox: an apparently acceptable argument for an apparently unacceptable conclusion—that we do not know anything about the external world. Some paradoxes, for instance the liar and the sorites, are very hard. The defense of a purported solution to either of these two inevitably deploys the latest in high-tech philosophical weaponry. On the other hand, some paradoxes are not at all hard, and may be resolved without much fuss. They do (...) not contain profound lessons about the human condition. Where should we place the sceptical paradoxes? (shrink)

Davidson’s later philosophy of language has been inspired by Wittgenstein’s Investigations, but Davidson by no means sympathizes with the sceptical problem and solution Kripke attributes to Wittgenstein. Davidson criticizes the sceptical argument for relying on the rule-following conception of meaning, which is, for him, a highly problematic view. He also casts doubt on the plausibility of the sceptical solution as unjustifiably bringing in shared practices of a speech community. According to Davidson, it is rather success in mutual (...) interpretation that explains success in the practice of meaning something by an utterance. I will argue that Davidson’s objections to the sceptical problem and solution are misplaced as they rely on a misconstrual of Kripke’s Wittgenstein’s view. I will also argue that Davidson’s alternative solution to the sceptical problem is implausible, since it fails to block the route to the sceptical problem. I will then offer a problematic trilemma for Davidson. (shrink)

To preserve freedom leibniz maintains that at any point in the development of the infinite series of a monad's states there will be an unlimited range of possible developments alternative to the actual. but if so a paradox analogous to kripke's arises. at any point in the development of an individual's states, no matter how far the series had developed, there would always be an unlimited number of rules, or concepts, the series could instantiate. but in such circumstances, it (...) would seem, god could not mean to create any particular individual.

The purpose of this paper is to provide a new solution to the radical sceptical paradox. A sceptical paradox purports to indicate the inconsistency within our fundamental epistemological commitments that are all seemingly plausible. Typically, sceptics employ an intuitively appealing epistemic principle (e.g., the closure principle, the underdetermination principle) to derive the sceptical conclusion. This paper will reveal a dilemma intrinsic to the sceptical paradox, which I refer to as the self-hollowing problem of (...) radical scepticism. That is, on the one hand, if the sceptical conclusion turns out to be true, then the epistemic principle employed by sceptics would lose its foundation of plausibility; on the other hand, if the sceptical conclusion does not follow, then the sceptical problem would not arise. In either case, the so-called sceptical paradox cannot be a genuine paradox. This new solution has three theoretical merits: it is undercutting, less theory-laden, and widely applicable. (shrink)

Starting with Wittgenstein’s remark about his allegedly frequent visits to the performance of Wagner’s Die Meistersinger von Nürnberg, the paper presents Wagner’s opera – being explicitly an opera about rules and rule-following – as a possible stimulus for the later Wittgenstein’s thinking about language. Besides Wittgenstein’s systematic interest in parallels between music and language, the paper draws on the choice of terminology and on Wittgenstein’s own examples of rule-following. More speculatively, the phrasing as well as the solution to what Kripke (...) called Wittgenstein’s sceptical paradox is used as a point of comparison that brings Wittgenstein’s aesthetic innuendos closer not only to mainstream philosophy of language, but due to the antithetical structure of Kripke’s argument, also to the broader philosophical and aesthetic tradition of German idealism.

The main aim of this paper is to analyse David Lewis’ version of contextualism and his solution to the Gettier problem and the lottery problem through the employment of his Rule of Relevance and Stewart Cohen’s response to these problems. Here I analyse whether Stewart Cohen’s response to David Lewis’ solutions to these problems is on the right track or not. Hence, I try to analyse some concept in David Lewis and Stewart Cohen which has remained unanalysed. Cohen tries to (...) show that when we try to solve some variation of the lottery problem and the Gettier problem by applying Lewis’s Rule of Relevance, then it generates some counterintuitive result. So Cohen gives Lewis some alternatives (which are explained in “The Strategy of Biting the Bullet and the Problem of Interference” and “Biting the Bullet Strategy as a Natural Extension of Contextualist Resolution to the Sceptical Problem and the Pity Poor Bill Variation of the Lottery Problem” sections) to avoid this counterintuitive result; this attempt, however, affects some other presuppositions of the contextual theory of David Lewis. My aim in this paper is to show how without taking these alternatives suggested by Cohen, Lewis can apply his Rules of Relevance to solve the lottery problem and the Gettier problem without any counterintuitive result.

A commitment to truth requires that you are open to receiving new evidence, even if that evidence contradicts your current beliefs. You should be open to changing your mind. However, this truism gives rise to the paradox of empathy. The paradox arises with the possibility of mental corruption through transformative change, and has consequences for how we should understand tolerance, disagreement, and the ability to have an open mind. I close with a discussion of how understanding this (...) class='Hi'>paradox provides a new explanation for a certain kind of standoff between the believer and the skeptic with regard to religious belief.

I present an argument for a sophisticated version of sceptical invariantism that has so far gone unnoticed: Bifurcated Sceptical Invariantism (BSI). I argue that it can, on the one hand, (dis)solve the Gettier problem, address the dogmatism paradox and, on the other hand, show some due respect to the Moorean methodological incentive of ‘saving epistemic appearances’. A fortiori, BSI promises to reap some other important explanatory fruit that I go on to adduce (e.g. account for concessive knowledge (...) attributions). BSI can achieve this much because it distinguishes between two distinct but closely interrelated (sub)concepts of (propositional) knowledge, fallible-but-safe knowledge and infallible-and-sensitive knowledge, and explains how the pragmatics and the semantics of knowledge discourse operate at the interface of these two (sub)concepts of knowledge. I conclude that BSI is a novel theory of knowledge discourse that merits serious investigation. (shrink)

Some philosophers understand epistemological skepticism as merely presenting a paradox to be solved, a paradox given rise to by some apparently forceful arguments. I argue that such a view needs to be justified, and that the best way to do so is to show that we cannot help seeing skepticism as obviously false. The obviousness (to us) of the falsity of skepticism is, I suggest, explained by the fact that we cannot live without knowledge-beliefs (a knowledge-belief about the (...) world is a belief that a person or a group of people know that p, where p is an empirical proposition about the world). I then go on to argue for the indispensability of knowledge-beliefs. The first line of argument appeals to the practical aspects of our employment of the concept of knowledge, and the second line of argument draws on some Davidsonian ideas concerning understanding and massive agreement.

In chapter 3 of Wittgenstein on Rules and Private Language, Kripke’s Wittgenstein offers a “sceptical solution" to the sceptical paradox about meaning developed in chapter 2 (according to which there are no facts in virtue of which ascriptions of meaning such as “Jones means addition by ‘+’” can be true). Although many commentators have taken the sceptical solution to be broadly analogous to non-factualist theories in other domains, such as non-cognitivism or expressivism in metaethics, the nature (...) of the sceptical solution has not been well-understood. The main aim of this paper is to advance our understanding of the nature of the non-factualism about meaning proposed in the sceptical solution. It attempts to outline some desiderata that should be respected by interpretations of the sceptical solution and considers two objections raised against it in Barry Stroud’s paper “Wittgenstein on Meaning, Understanding and Community". It attempts to correct misconstruals of the sceptical solution that have been promulgated by Davidson and some of his followers and suggests that the sceptical solution developed by Kripke’s Wittgenstein is best viewed as a form of quasi-realism about meaning. It ends by outlining what it takes to be the most pressing challenges facing the sceptical solution. (shrink)

A Sceptical Theory of Scientific Inquiry: Problems and Their Progress presents a distinctive re-interpretation of Popper's 'critical rationalism', displaying the kind of spirit found at the L.S.E. before Popper's retirement. It offers an alternative to interpretations of critical rationalism which have emphasised the significance of research programmes or metaphysics (Lakatos; Nicholas Maxwell), and is closer to the approach of Jagdish Hattiangadi. Briskman gives priority to methodological argument rather than logical formalisms, and takes further his own work on creativity. In (...) addition to offering an important contribution to the understanding of critical rationalism, the book contains interesting engagements with Michael Polanyi and the Meno Paradox. This volume also contains an introduction by the editor, which situates Briskman's work in the history of the interpretation of 'critical rationalism'. (shrink)

Do we really know the things we think we know? Are any of our beliefs reasonable? Scepticism gives a pessimistic reply to these important epistemological questions - we don't know anything; none of our beliefs are reasonable. But can such a seemingly paradoxical claim be more than an intellectual curiousity? And if it is, can it be refuted? Ruth Weintraub answers yes to both these questions. The sceptical challenge is a formidable one, and should be confronted, not dismissed. The (...) theoretical and practical difficulties it presents - in that the sceptical life cannot be lived, and the doctrine seems self-defeating - are in fact superficial, according to Ruth Weintraub. Her study looks at the sceptical arguments of Descartes, Hume and the ancient Greek sceptic, Sextus Empiricus. The author argues that by drawing on philosophy, rather than science, the sceptical challenge can be answered. _The Sceptical Challenge_ is a bold and original response to scepticism; it represents a new way of looking at the field for philosophers of epistemology.

John Henry Newman starts the second half of the Grammar of Assent by laying out a “paradox,” and he announces that the purpose of the following chapters of the book is to resolve it. Surprisingly, recent scholarship has tended not to question the nature of this paradox. In this paper, I argue that we should understand Newman’s paradox to be a kind of skeptical paradox that arises when we accept “Lockean rationalism.” I then show how Newman (...) deals with the paradox. One of the upshots of this reading is that “naturalism” plays a smaller role in Newman’s anti-skepticism than previous commentators have suggested. Another is that we should understand Newman to be a kind of infallibilist. (shrink)

Предлагается виттгенштайновское решение скептического парадокса Крипке, который возникает в результате пренебрежения прагматикой и нормативным измерением производимых операций. Парадокс Крипке указывает на то, что натурализация смысла и проблемы следования правилу в рамках классического (ненормативного) натурализма невозможна. Анализируется и критикуется недавно предложенная Гинзборг интерпретация парадокса. Хотя её натуралистический «срединный путь» между диспозиционализмом и ментализмом и близок к нормативному виттгенштайновскому натурализму, вводимое ею понятие примитивной нормативности неудовлетворительно. Правильнее говорить не о натурализме с минимальным добавлением нормативности, как это делает Гинзборг, а о нормативном натурализме.

Climate scepticism in the sense of climate denialism or contrarianism is not a new phenomenon, but it has recently been very much in the media spotlight. When, in November 2009, emails by climate scientists were published on the internet without their authors' consent, a debate began in which climate sceptic bloggers used an extended network of metaphors to contest science. This article follows the so-called 'climategate' debate on the web and shows how a paradoxical mixture of religious metaphors and demands (...) for 'better science' allowed those disagreeing with the theory of anthropogenic climate change to undermine the authority of science and call for political inaction with regard to climate change.

RESUMEN Se cuestionan las dos conclusiones imputadas a la aplicación de la "paradoja escéptica de Wittgenstein" al derecho, tal como es desarrollada por S. Kripke. A saber, o bien la paradoja se aplica a la práctica del derecho y esta es indeterminada e imposible, o bien aquella es completamente irrelevante para la práctica del derecho y la reflexión filosófica sobre este. Se sugiere que la filosofía del derecho puede aceptar la relevancia de esta paradoja y obtener nuevos elementos a partir (...) de ella. ABSTRACT The article questions the two conclusions attributed to the application of "Wittgenstein's skeptical paradox" to law, as developed by S. Kripke: that is, either the paradox is applied to the practice of law and it is indeterminate or impossible, or the paradox is completely irrelevant for the practice of law and for philosophical reflection in that respect. The paper suggests that philosophy of right can accept the relevance of the paradox and draw new elements from it. (shrink)

There is an epistemological skepticism that I might be dreaming now, or I might be a brain in a vat (BIV). There is also a demonstration that derives the skeptical conclusion about knowledge of the external world from the premise C1, i.e., I do not know “I am not dreaming (not a BIV) now.” Pessimistic critics (e.g., F. Strawson, B. Stroud) consider that the refutation of C1 is impossible, whereas others have attempted the direct refutation of C1 (e.g., G. E. (...) Moore, H. Putnam, C. Wright), and some (e.g., F. Dretske, R. Nozick) have attempted to refute the closure principle of knowledge used in the demonstration while permitting the validity of C1. Another scholar, M. Williams, maintains that the skeptical demonstration is true only if we presuppose the epistemological premise that we choose to accept or reject at will. It seems that most critics tend to adopt a strategy that allows them to effectively avoid the skeptical consequence, thereby conceding the validity of C1. However, it is difficult to say whether their attempts succeeded, and in my opinion, they are indeed unsuccessful. This is because their concession to Descartes’ argument is insufficient. Their lack of success could also stem from the incompletion of Descartes’ own methodological doubt. The somewhat paradoxical‐sounding aim of this thesis is to show that the skeptical paradox about knowledge can be dissolved only if the Cartesian skepticism is extended far beyond the endpoint of his attempt. The argument of this thesis is based on the important arguments of Wittgenstein's On Certainty （OC）. (shrink)

Anthony Brueckner has argued that claims about underdetermination of evidence are suppressed in closure-based scepticism (“The Structure of the Skeptical Argument”, Philosophy and Phenomenological Research 54:4, 1994). He also argues that these claims about underdetermination themselves lead to a paradoxical sceptical argument—the underdetermination argument—which is more fundamental than the closure argument. If Brueckner is right, the status quo focus of some predominant anti-sceptical strategies may be misguided. In this paper I focus specifically on the relationship between these two (...) arguments. I provide support for Brueckner’s claim that the underdetermination argument is the more fundamental sceptical argument. I do so by responding to a challenge to this claim put forward by Stewart Cohen (“Two Kinds of Skeptical Argument”, Philosophy and Phenomenological Research 58:1, 1998). Cohen invokes an alternative epistemic principle which he thinks can be used to challenge Brueckner. Cohen’s principle raises interesting questions about the relationship between evidential considerations and explanatory considerations in the context of scepticism about our knowledge of the external world. I explore these questions in my defence of Brueckner. (shrink)

Moore's proof of an external world is a piece of reasoning whose premises, in context, are true and warranted and whose conclusion is perfectly acceptable, and yet immediately seems flawed. I argue that neither Wright's nor Pryor's readings of the proof can explain this paradox. Rather, one must take the proof as responding to a sceptical challenge to our right to claim to have warrant for our ordinary empirical beliefs, either for any particular empirical belief we might have, (...) or for belief in the existence of an external world itself. I show how Wright's and Pryor's positions are of interest when taken in connection with Humean scepticism, but that it is only linking it with Cartesian scepticism which can explain why the proof strikes us as an obvious failure.

The “sceptical” solution to the paradox which Kripke attibutes to Wittgenstein is supposed to lead to the conclusion that there is a sense in which thought and language are essentially social phenomena. In the following, I argue that both the “sceptical” and the “communautarian” character of this solution can be questioned, though without having to agree with Davidson, according to whom the solution to this paradox does not depend on any notion of a common language.

Resumo Embora controversa, o contextualismo epistêmico alega oferecer a melhor explicação para alguns fenômenos analisados em epistemologia contemporânea, por exemplo: alega responder ou explicar o apelo de certos paradoxos e, ao mesmo tempo, manter a verdade de nossas alegações ordinárias de conhecimento. Conforme alegado por contextualistas, a vantagem de sua teoria ao explicar o apelo de certos paradoxos reside no fato de que nenhum princípio lógico precisa ser rejeitado. O paradoxo do prefácio – que consiste na aparente incoerência lógica que (...) ocorre quando o autor de um livro declara em seu prefácio que, apesar de acreditar que é altamente provável que tudo o que o livro afirma seja verdadeiro, também é altamente provável que o livro contenha, pelo menos, algum erro – parece não ter sido explorado o suficiente pelos contextualistas. Portanto, pretendemos sugerir uma versão do paradoxo do prefácio apresentando um argumento análogo ao argumento que os contextualistas costumam apresentar para explicar o paradoxo cético. Desta maneira, pretendemos oferecer, por meio de uma análise contextualista, uma explicação para o paradoxo do prefácio. Se a resposta contextualista é ou não adequada para esse paradoxo, isso será questão de disputa e não nos caberá discuti-la aqui. Meu objetivo é apenas sugerir que uma análise contextualista semelhante à aplicada ao paradoxo cético pode ser construída para explicar o paradoxo do prefácio. Palavras-chave: Contextualismo; Paradoxo do prefácio; Paradoxo cético. (shrink)

This book addresses what is generally regarded as the most crucial and yet most controversial problem in Hume's philosophy, namely, the nature of his scepticism and realism. John Wright argues against those who emphasize either the sceptical or realist strains in Hume's thought or who despair of ever finding any consistency in it. The paradoxical title of the book indicates the author's claim to have reconciled these two strains into a unified theory.

It is true of many truths that I do not believe them. It is equally true, however, that I cannot rationally assert of any such truth both that it is true and that I do not believe it. To explain why this is so, I will distinguish absence of belief from disbelief and argue that an assertion of “p, but I do not believe that p” is paradoxical because it is indefensible, i.e. for reasons internal to it unable to convince. (...) A closer examination of the irrationality involved will show that such is the skeptic’s predicament, trying to convince us to bracket knowledge claims we have good grounds to take ourselves to be entitled to. Even if the sceptic cannot be proven wrong, his challenge still demands an answer, if not a treatment. In this paper, I argue that the cure lies in epidemiology rather than epistemology: instead of attacking the sceptic head-long, I commend guerilla tactics, vaccinating our fellow non-sceptics against the sceptical virus. I will not argue that the sceptic is wrong, necessarily wrong or that he cannot be believed, but that he cannot convince. Scepticism requires a leap of faith: something we may justifiably refrain from even on the sceptic’s own standards. (shrink)

An evolutionary approach to ethics supports, to some extent, the sceptical meta-ethics found by some of the Greek sophists and Nietzsche. On the other hand, a modern naturalistic account on the origin and nature of morality, leads to somewhat different conclusions. This is demonstrated with an answer to three philosophical questions: does real freedom exist?, does the good, or real virtue, exist?, does life have a meaning?

An advanced artificial intelligence could pose a significant existential risk to humanity. Several research institutes have been set-up to address those risks. And there is an increasing number of academic publications analysing and evaluating their seriousness. Nick Bostrom’s superintelligence: paths, dangers, strategies represents the apotheosis of this trend. In this article, I argue that in defending the credibility of AI risk, Bostrom makes an epistemic move that is analogous to one made by so-called sceptical theists in the debate about (...) the existence of God. And while this analogy is interesting in its own right, what is more interesting are its potential implications. It has been repeatedly argued that sceptical theism has devastating effects on our beliefs and practices. Could it be that AI-doomsaying has similar effects? I argue that it could. Specifically, and somewhat paradoxically, I argue that it could amount to either a reductio of the doomsayers position, or an important and additional reason to join their cause. I use this paradox to suggest that the modal standards for argument in the superintelligence debate need to be addressed. (shrink)

This paper reflects on a simple, ingenious and celebrated result by Amartya Sen, ‘The Impossibility of a Paretian Liberal’ (1970). Sen’s result, sometimes called the 'Liberal Paradox', has attracted — particularly in the years soon after its publication — a vast literature, including responses and reflections from Sen himself. Much of the literature involves attempts to ‘escape’ the Liberal Paradox by proposing ways to avoid or resolve the problem it seems to identify. But despite the extensive attention, and (...) perhaps a sense among philosophers in related areas that the result is somehow relevant to liberalism or to political philosophy in general, it is still not clear why the result matters philosophically. I am sceptical about the significance of the Liberal Paradox: in this paper, I articulate various ways in which political philosophers might be urged to care about the Paradox, and argue that each of them is either implausible or of only moderate interest.

This monograph presents Azzouni’s new approach to the rule-following paradox. His solution leaves intact an isolated individual’s capacity to follow rules, and it simultaneously avoids replacing the truth conditions for meaning-talk with mere assertability conditions for that talk. Kripke’s influential version of Wittgenstein’s rule-following paradox—and Wittgenstein’s views more generally—on the contrary, make rule-following practices and assertions about those practices subject to community norms without which they lose their cogency. Azzouni summarizes and develops Kripke’s original version of Wittgenstein’s rule-following (...) paradox to make salient the linchpin assumptions of the paradox. By doing so, Azzouni reveals how compelling Kripke’s earlier work on the paradox was. Objections raised over the years by Fodor, Forbes Ginsborg, Goldfarb, Tait, Wright, and many others, are all shown to fail. No straight solution can be made to work. Azzouni illustrates this in detail by showing that a popular family of straight solutions due to Lewis and refined by Williams, “reference magnetism,” fail as well. And yet an overlooked sceptical solution is still available in logical space. Azzouni describes a series of “disposition-meaning” private languages that he shows can be successfully used by a population of speakers to communicate with one another despite their ideolectical character. The same sorts of languages enable solitary “Robinson Crusoes” to survive and flourish in their island habitats. These languages—sufficiently refined—have the same properties normal human languages have; and this is the key to solving the rule-following paradox without sacrificing the individual’s authority over her self-imposed rules or her ability to follow those rules. Azzouni concludes this unusual monograph by uncovering a striking resemblance between the rule-following paradox and Hume’s problem of induction: he shows the rule-following paradox to be a corollary of Hume’s problem that arises when the problem of induction is applied to an individual’s own abilities to follow rules.

The Kripke/Wittgenstein paradox and Goodman’s riddle of induction can be construed as problems of multiple redescription, where the relevant sceptical challenge is to provide factual grounds justifying the description we favour. A choice of description or predicate, in turn, is tantamount to the choice of a curve over a set of data, a choice apparently governed by implicitly operating constraints on the relevant space of possibilities. Armed with this analysis of the two paradoxes, several realist solutions of Kripke’s (...) paradox are examined that appeal to dispositions or other non-occurrent properties. It is found that all neglect crucial epistemological issues: the entities typically appealed to are not observational and must be inferred on the basis of observed entities or events; yet, the relevant sceptical challenge concerns precisely the factual basis on which this inference is made and the constraints operating on it. All disposition ascriptions, the thesis goes on to argue, contain elements of idealization. To ward off the danger of vacuity resulting from the fact that any disposition ascription is true under just the right ideal conditions, dispositional theories need to specify limits on legitimate forms of idealization. This is best done by construing disposition ascriptions as forms of (implicit) curve-fitting, I argue, where the “data” is not necessarily numeric, and the “curve” fitted not necessarily graphic. This brings us full circle: Goodman’s and Kripke’s problems are problems concerning curve-fitting, and the solutions for it appeal to entities the postulation of which is the result of curve-fitting. The way to break the circle must come from a methodology governing the idealizations, or inferences to the best idealization, that are a part of curve-fitting. The thesis closes with an argument for why natural science cannot be expected to be of much help in this domain, given the ubiquity of idealization. (shrink)

Taking the Liar paradox as an object lesson, Benson Mates argues that the major problems of philosophy remain intractable: they will never be resolved to the satisfaction of every competent investigator. In particular, "every clever attempt to solve" the whole question of skepticism regarding the External World "seems only to reveal that it is even deeper and more fundamental than it previously appeared to be." But that remark suggests an uncharacteristic optimism that is otherwise absent from the main drift (...) of the book, as if an ever deepening Socratic ignorance were at any rate available to us. (shrink)

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.

Psychological failure to legislate norms from a state of normative nil is the core sceptical case that German philosophy had left unsolved, and that after Kant was handed over to each new generation of philosophers, until it exploded with great force in debates that spanned the 1910s. This article seeks to provide a context for Carl Schmitt's statement that `nobody could ever describe a single person's intentions as a norm', and to link this kind of normative scepticism with Schmitt's (...) later notion of `exception'. In the face of several attempts to dismiss Schmitt's theory in light of his personal and professional allegiance to the Nazis, this article appeals to the possibility of consilium pravorum, the idea that one can learn from someone whose ideas or actions are despicable. Schmitt distinguishes himself (especially in his early works before 1922) for both his normative scepticism and his willingness to interrogate premises that contemporary political philosophy seems to have left unexamined.

Saul Kripke is struck by a skeptical argument which he says is neither Wittgenstein’s nor his own. I call this new skeptic “Saul Wittgenstein”. SW’s conclusion is that there is no such thing as following a rule. My first aim is to show that Kripke misunderstands the Investigations when he says it offers a “skeptical solution” to SW’s paradox. Wittgenstein’s view of philosophy commits him to a dissolution of the paradox. I show next that LW’s writing contains an (...) implicit dissolution of it. Finally, I point out the main lesson to be derived from Kripke’s discussion--namely, that there is nothing which is common and peculiar to what we call following a rule. (shrink)

From A. N. Whitehead, his senior collaborator in the classic work on mathematical logic which established his philosophical reputation, Bertrand Russell once provoked the exasperated remark: “Bertie, you’re an aristocrat, not a gentleman”. To-day having matured in the lived experience of eighty-five years and having spanned this century with widely-publicised books, articles and lectures, Russell remains a living paradox in whom the cool logician, the social prophet and the tantalising polemist have yet to achieve integration. Issuing from an established (...) intellectual family with a precociously questioning mind and a moral courage equal to the assertion of any truth, educating himself to a razor-keen mind and a mastery of lucid prose, he has adopted the public role of a witty sophist as well as an iconoclast angry with conservative convention in moral, social and religious conduct. Theoretically practical conduct is a realm of private feeling and not of objective truth in his philosophy, which he implements with literal freedom. Nevertheless he must be conscious that his polemic often falls short of the standard of a disciplined respect for truth, though he might explain away this defect by referring to the accepted rules of the game which he plays…hard. Yet his biographer notes that he resents criticism of his moral and social writings more than of his purely academic work. And his aim, as expressed in a letter from Brixton prison in 1918 where an embarrassed government confined his biting pacifism, is constructive: “There is a little wisdom in the world; Heraclitus, Spinoza, and a saying here and there. I want to add to it, even if only ever so little”. (shrink)
