Metaphilosophical Skepticism

In some domains experts perform better than novices, and in other domains experts do not generally perform better than novices. According to empirical studies of expert performance, this is because the former but not the latter domains make available to training practitioners a direct form of learning feedback. Several philosophers resource this empirical literature to cast doubt on the quality of philosophical expertise. They claim that philosophy is like the dubious domains in that it does not make available the good, (...) direct kind of learning feedback, and thus there are empirical grounds for doubting the epistemic quality of philosophical expertise. I examine the empirical studies that are purportedly bad news for professional philosophers. On the basis of that examination, I provide three reasons why the empirical study of non-philosophical expertise does not undermine the status of philosophical expertise. First, the non-philosophical task-types from which the critics generalize are unrepresentative of relevant philosophical task-types. Second, empirical critiques of non-philosophical experts are often made relative to the performance of linear models—a comparison that is inapt in a philosophical context. Third, the critics fail to discuss findings from the empirical study of non-philosophical expertise that have more favorable implications for the epistemic status of philosophical expertise. In addition to discussing implications for philosophical expertise, this article makes progress in the philosophical analysis of the science of expertise and expert development. (shrink)

Many philosophers are sceptical about the power of philosophy to refute commonsensical claims. They look at the famous attempts and judge them inconclusive. I prove that even if those famous attempts are failures, there are alternative successful philosophical proofs against commonsensical claims. After presenting the proofs I briefly comment on their significance.

Conceptual Engineering alleges that philosophical problems are best treated via revising or replacing our concepts (or words). The goal here is not to defend Conceptual Engineering but rather show that it can (and should) invoke Neutralism—the broad view that philosophical progress can take place when (and sometimes only when) a thoroughly neutral, non-specific theory, treatment, or methodology is adopted. A neutralist treatment of one form of skepticism is used as a case study and is compared with various non-neutral rivals. Along (...) the way, a new taxonomy for paradox is proposed. (shrink)

Philosophers defend, and often believe, controversial philosophical claims. Since they aren’t clueless, they are usually aware that their views are controversial—on some occasions, the views are definitely in the minority amongst the relevant specialist-experts. In addition, most philosophers are aware that they are not God’s gift to philosophy, since they admit their ability to track truth in philosophy is not extraordinary compared to that of other philosophers. In this paper I argue that in many real-life cases, such beliefs in controversial (...) claims are irrational. This means that most philosophers have irrational philosophical beliefs. (shrink)

Global meta-philosophical skepticism (i.e. completely unrestricted skepticism about philosophy) based upon disagreement faces the problem of self-defeat since it undercuts its motivating conciliatory principle. However, the skeptic may easily escape this threat by adopting a more modest kind of skepticism, that will be called “extensive meta-philosophical skepticism”, i.e., the view that most of our philosophical beliefs are unjustified, except our beliefs in epistemically fundamental principles. As I will argue in this paper, this kind of skepticism is well-motivated, does not undercut (...) the conciliatory principle, but still poses a radical challenge to philosophy as a cognitive discipline. Moreover, I will argue that non-global skepticism that is still extensive undermines itself as well. The deeper reason for this is that this more modest kind of skepticism can only be motivated by the assumption that disagreement with philosophical peers is abundant and that we can identify peers only by relying on track-record arguments. But then one can argue for extensive meta-philosophical skepticism only if one presupposes that those philosophical beliefs that form the basis of track-record evaluations are justified. Here, the threat of self-defeat looms again. I will proceed by first defending the premises of this new anti-skeptical argument against standard objections from the literature. Second, I will show in more detail where the epistemic inconsistency arises in the argument for extensive meta-philosophical skepticism. I conclude with an assessment of the scope and the limits of my argument. (shrink)

"La gente dice una y otra vez que la filosofía no progresa realmente, que todavía estamos ocupados con los mismos problemas filosóficos que los griegos. Pero la gente que dice esto no entiende por qué tiene que ser así. Es porque nuestro lenguaje ha permanecido igual y nos sigue seduciendo para que hagan las mismas preguntas. Mientras siga habiendo un verbo "ser" que parezca como si funciona de la misma manera que "comer y beber", siempre y cuando todavía tengamos los (...) adjetivos "idénticos", "verdaderos", "falsos", "posibles", siempre y cuando sigamos hablando de un río de tiempo, , de una extensión de espacio, etc., etc., la gente seguirá tropezando con las mismas dificultades desconcertante y se encontrará mirando a algo que ninguna explicación parece capaz de aclarar. Y lo que es más, esto satisface un anhelo de lo trascendente, porque, en la medida en que la gente cree que puede ver el ‘límites de la comprensión humana ́, creen, por supuesto, que pueden ver más allá de estos. ' ' Esta cita es de Ludwig Wittgenstein que redefinió la filosofía hace unos 70 años (pero la mayoría de la gente todavía tiene que averiguarlo). Dennett, aunque ha sido un filósofo desde hace unos 40 años, es uno de ellos. También es curioso que tanto él como su antagonista principal, John Searle, estudiaron bajo los famosos Wittgensteinianos (Searle con John Austin, Dennett con Gilbert Ryle) pero Searle Más o menos consiguió el punto y Dennett no, (aunque se está estirando cosas para llamar Searle o Ryle Wittgensteinianos). Dennett es un determinista duro (aunque intenta escabullirse de la realidad en la puerta trasera), y tal vez esto se deba a Ryle, cuyo famoso libro ́el concepto de la mente ́ (1949) continúa siendo reimpreso. Ese libro hizo un gran trabajo de exorcizar al fantasma, pero dejó la máquina. A Dennett le gusta cometer los errores que Wittgenstein, Ryle (y muchos otros desde entonces) han expuesto en detalle. Nuestro uso de las palabras consciencia, elección, libertad, intención, partícula, pensamiento, determina, oleada, causa, ocurrió, evento (y así sucesivamente) raramente son una fuente de confusión, pero tan pronto como dejamos la vida normal y entramos en la filosofía (y cualquier discusión separada del entorno en el que el lenguaje evolucionó— es decir, el contexto exacto en el que las palabras tenían sentido) reina el caos. Como la mayoría, Dennett carece de un marco coherente - que Searle ha llamado la estructura lógica de la racionalidad. Me he expandido en este considerablemente desde que escribí esta reseña y mis artículos recientes muestran en detalle lo que está mal con el enfoque de Dennett a la filosofía, que uno podría llamar scientismo en esteroides.

There is an old meta-philosophical worry: very roughly, metaphysical theories have no observational consequences and so the study of metaphysics has no value. The worry has been around in some form since the rise of logical positivism in the early twentieth century but has seen a bit of a renaissance recently. In this paper, I provide an apology for metaphysics in the face of this kind of concern. The core of the argument is this: pure mathematics detaches from science in (...) much the same manner as metaphysics and yet it is valuable nonetheless. The source of value enjoyed by pure mathematics extends to metaphysics as well. Accordingly, if one denies that metaphysics has value, then one is forced to deny that pure mathematics has value. The argument places an added burden on the sceptic of metaphysics. If one truly believes that metaphysics is worthless (as some philosophers do), then one must give up on pure mathematics as well.

Helen Beebee (2018) defends a view of the aims of philosophy she calls ‘equilibrism’. Equilibrism denies that philosophy aims at knowledge and maintains that the collective aim of philosophy is ‘to find what equilibria there are that can withstand examination’ (Beebee 2018, p. 3). In this note, I probe equilibrism by focusing on how disagreement challenges our doxastic commitment to our own philosophical theories. Call this the Commitment Challenge. I argue that the Commitment Challenge comes in three varieties and that (...) endorsing equilibrism provides us with an answer to one of them only. (shrink)

This article argues, first, that there is plenty of agreement among philosophers on philosophically substantive claims, which fall into three categories: reasons for or against certain views, elementary truths regarding fundamental notions, and highly conditionalized claims. This agreement suggests that there is important philosophical progress. It then argues that although it's easy to list several potential kinds of philosophical progress, it is much harder to determine whether the potential is actual. Then the article attempts to articulate the truth that the (...) deniers of philosophical progress are latching on to. Finally, it comments on the significance of the agreement and progress.

Materialism, reductionism, behaviorism, functionalism, dynamic systems theory and computationalism are popular views, but they were shown by Wittgenstein to be incoherent. The study of behavior encompasses all of human life but behavior is largely automatic and unconscious and even the conscious part, mostly expressed in language (which Wittgenstein equates with the mind), is not perspicuous, so it is critical to have a framework which Searle calls the Logical Structure of Rationality (LSR) and I call the Descriptive Psychology of Higher Order (...) Thought (DPHOT). After summarizing the framework worked out by Wittgenstein and Searle, as extended by modern reasoning research, I comment on this first book in a trilogy on Human Nature by the leading authority on Wittgenstein. -/- Those wishing a comprehensive up to date framework for human behavior from the modern two systems view may consult my article The Logical Structure of Philosophy, Psychology, Mind and Language as Revealed in Wittgenstein and Searle 59p(2016).

A new kind of skepticism about philosophy is articulated and argued for. The key premise is the claim that many of us are well aware that in the past we failed to have good responses to substantive objections to our philosophical beliefs. The conclusion is disjunctive: either we are irrational in sticking with our philosophical beliefs, or we commit some other epistemic sin in having those beliefs.

In this paper, I sketch an answer to the question “Why be an intellectually humble philosopher?” I argue that, as far as philosophical argumentation is concerned, the historical record of Western Philosophy provides a straightforward answer to this question. That is, the historical record of philosophical argumentation, which is a track record that is marked by an abundance of alternative theories and serious problems for those theories, can teach us important lessons about the limits of philosophical argumentation. These lessons, in (...) turn, show why philosophers should argue with humility. (shrink)

Fumerton’s distinctive brand of metaepistemological scepticism is compared and contrasted with the related position outlined by Stroud. It is argued that there are at least three interesting points of contact between Fumerton and Stroud’s metaepistemology. The first point of contact is that both Fumerton and Stroud think that (1) externalist theories of justification permit a kind of non-inferential, perceptual justification for our beliefs about non-psychological reality, but it’s not sufficient for philosophical assurance. However, Fumerton claims, while Stroud denies, that (2) (...) direct acquaintance with facts is sufficient for philosophical assurance. And this is important because Stroud thinks that (3) we have direct perceptual access or acquaintance with facts about the external world, while Fumerton denies this. (shrink)

Disagreement has been grist to the mills of sceptics throughout the history of philosophy. Recently, though, some philosophers have argued that widespread philosophical disagreement supports a broad scepticism about philosophy itself. In this paper, I argue that the task for sceptics of philosophy is considerably more complex than commonly thought. The mere fact that philosophical methods fail to generate true majority views is not enough to support the sceptical challenge from disagreement. To avoid demanding something that human reasoning cannot supply, (...) sceptics must show that philosophers have sufficient overlap to resolve their disagreements in particular concrete cases. (shrink)

Wittgenstein (W) is for me easily the most brilliant thinker on human behavior and this is his last work and crowning achievement. It belongs to his third and final period, yet it is not only his most basic work (since it shows that all behavior is an extension of innate true-only axioms and that our conscious ratiocination is but icing on unconscious machinations), but as Daniele Moyal-Sharrock has recently noted, is a radical new epistemology and the foundation for all description (...) of animal behavior, revealing how the mind works and indeed must work. The "must" is entailed by the fact that all brains share a common ancestry and common genes, and so there is only one basic way they work, that this necessarily has an axiomatic structure, that all higher animals share the same evolved psychology based on inclusive fitness, and in humans this is extended into a personality based on throat muscle contractions (language) that evolved to manipulate others (with variations that can be regarded as trivial). This book, and arguably all of W's work and all useful discussion of behavior is a development of or variation on these ideas. -/- Those wishing a comprehensive up to date framework for human behavior from the modern two systems view may consult my book ‘The Logical Structure of Philosophy, Psychology, Mind and Language in Ludwig Wittgenstein and John Searle’ 2nd ed (2019).

The epistemological problem of the external world asks: (1) “How is knowledge of the world possible given certain obstacles which make it look impossible?” This is a “how-possible?” question: it asks how something is possible given certain obstacles which make it look impossible (cf. Cassam 2007; Nozick 1981; Stroud 1984). Now consider the following question, which asks: (2) “How is a philosophically satisfying answer to (1) possible?” Scepticism is the thesis that knowledge of the world is impossible. It therefore represents (...) a negative answer to the first question. Meta-epistemological scepticism is the thesis that a satisfying philosophical explanation of how our knowledge of the world is possible is itself not possible. It therefore represents a negative answer to the second question. In this thesis, I explore the prospects of meta-epistemological scepticism. In particular, I structure the thesis around two master arguments from Stroud (1984, 2000, 2004, and 2009) for meta-epistemological scepticism. The first argument is what I call “Stroud’s puzzle”, and the second argument is “Stroud’s dilemma” (cf. Cassam 2009). I argue that Stroud’s puzzle fails to provide adequate support for meta-epistemological scepticism. However, I also argue that Stroud’s dilemma withstands serious objections (e.g., from Sosa 1994, Williams 1996, and Cassam 2009). In short, while Stroud’s puzzle fails to provide adequate support for meta-epistemological scepticism, Stroud’s dilemma does seem to provide adequate support for meta-epistemological scepticism. This thesis therefore represents a partial defence of meta-epistemological scepticism. Meta-epistemological scepticism is therefore a live option in epistemology. (shrink)

In this paper, I argue that, just as the problem of unconceived alternatives provides a basis for a New Induction on the History of Science to the effect that a realist view of science is unwarranted, the problem of unconceived objections provides a basis for a New Induction on the History of Philosophy to the effect that a realist view of philosophy is unwarranted. I raise this problem not only for skepticism’s sake but also for the sake of making a (...) point about philosophical argumentation, namely, that anticipating objections to one’s claim is not the same as supporting one’s claim. In other words, defending p from objections does not amount to support or evidence for p. This, in turn, presents dialectical and pragma-dialectical approaches to argumentation with the following question: does proper argumentation require that arguers anticipate and respond to unconceived objections? (shrink)

This paper argues that higher-order doubt generates an epistemic dilemma. One has a higher-order doubt with regards to P insofar as one justifiably withholds belief as to what attitude towards P is justified. That is, one justifiably withholds belief as to whether one is justified in believing, disbelieving, or withholding belief in P. Using the resources provided by Richard Feldman’s recent discussion of how to respect one’s evidence, I argue that if one has a higher-order doubt with regards to P, (...) then one is not justified in having any attitude towards P. Otherwise put: No attitude towards the doubted proposition respects one’s higher-order doubt. I argue that the most promising response to this problem is to hold that when one has a higher-order doubt about P, the best one can do to respect such a doubt is to simply have no attitude towards P. Higher-order doubt is thus much more rationally corrosive than non-higher-order doubt, as it undermines the possibility of justifiably having any attitude towards the doubted proposition. (shrink)

If you retain your belief upon learning that a large number and percentage of your recognized epistemic superiors disagree with you, then what happens to the epistemic status of your belief? I investigate that theoretical question as well has the applied case of philosophical disagreement—especially disagreement regarding purely philosophical error theories, theories that do not have much empirical support and that reject large swaths of our most commonsensical beliefs. I argue that even if all those error theories are false, either (...) (a) the average philosopher’s true commonsensical beliefs are epistemically impoverished, or (b) a good portion of philosophy is bunk and philosophers should give up most of their error theories despite the fact that their supporting arguments are generally as good as or even better than other philosophical arguments. (shrink)

In philosophy, as in many other disciplines and domains, stable disagreement among peers is a widespread and well-known phenomenon. Our intuitions about paradigm cases, e.g. Christensen's Restaurant Case, suggest that in such controversies suspension of judgment is rationally required. This would prima facie suggest a robust suspension of judgment in philosophy. But we are still lacking a deeper theoretical explanation of why and under what conditions suspension is rationally mandatory. In the first part of this paper I will focus on (...) this question. After a critical survey of some recent alternative approaches (diversity as a thread to the reliability, decision problem, acquisition of undercutting defeaters), I will argue that in fact discovering disagreement with an opponent provides me with a rebutting defeater, but only if some further non-trivial conditions are satisfied - among them my acknowledging her as my reliability peer. In the second part of the paper I will explore in more detail the skeptical implications this account has for philosophy. Here, I will defend two claims. First, skepticism about philosophy is mandatory only if the relevant peerness assumption can be justified. Second, in philosophy there is no basis available that would support the relevant peerness assumption. If this is correct, we are not forced into skepticism about philosophy and may rationally retain our philosophical beliefs even in the face of controversy. (shrink)

Considering three philosophers – Ghazali , Hume, and Kant – we perceive that they were at grips with skepticism and each had a different attitude towards it. While Hume remains in a skeptical sphere, Ghazali and Kant offer solutions for skepticism, although their solutions differ largely. Criticizing Aristotle’s view on essential necessity, Ghazali expands Avicenna’s emphasis on experimentation and, in effect, negates the necessary relation between cause and effect. Ghazali preceded Hume in this regard for some 6 centuries and put (...) forward Hume’s main idea. In order to overcome skepticism, Kant appealed to rationality and it’s a priori backgrounds, while Ghazali put forward God’s will and put the emphasis on the inner direct experience. It will be argued that God’s deeds, rationality and faith should be compatible in principle. (shrink)

An argument is epistemically self-defeating when either the truth of an argument’s conclusion or belief in an argument’s conclusion defeats one’s justification to believe at least one of that argument’s premises. Some extant defenses of the evidentiary value of intuition have invoked considerations of epistemic self-defeat in their defense. I argue that there is one kind of argument against intuition, an unreliability argument, which, even if epistemically self-defeating, can still imply that we are not justified in thinking intuition has evidentiary (...) value.

Abstract Timothy Williamson has recently proposed to undermine modal skepticism by appealing to the reducibility of modal to counterfactual logic ( Reducibility ). Central to Williamson’s strategy is the claim that use of the same non-deductive mode of inference ( counterfactual development , or CD ) whereby we typically arrive at knowledge of counterfactuals suffices for arriving at knowledge of metaphysical necessity via Reducibility. Granting Reducibility, I ask whether the use of CD plays any essential role in a Reducibility-based reply (...) to two kinds of modal skepticism. I argue that its use is entirely dispensable, and that Reducibility makes available replies to modal skeptics which show certain propositions to be metaphysically necessary by deductive arguments from premises the modal skeptic accepts can be known.

Suppose you know that someone is your epistemic peer regarding some topic. You admit that you cannot think of any relevant epistemic advantage you have over her when it comes to that topic; you admit that she is just as likely as you to get P's truth-value right. Alternatively, you might know that she is your epistemic superior regarding the topic. And then after learning this about her you find out that she disagrees with you about P. In those situations (...) it appears that the confidence with which one holds one's belief should be significantly reduced. My primary goal in this essay is to present and reflect upon a set of cases of disagreement that have not been discussed in the literature but are vital to consider. I argue that in the new cases one is reasonable in not lowering one?s confidence in the belief. Then I articulate and defend an ambitious principle, the Disagreement Principle, meant to answer the question 'Under what conditions am I epistemically blameworthy in retaining my belief with the same level of confidence after I have discovered recognized peers or superiors who disagree with me?'.

My topic is two-fold: a reductive account of expertise as an epistemic phenomenon, and applying the reductive account to the question of whether or not philosophers enjoy expertise. I conclude, on the basis of the reductive account, that even though philosophers enjoy something akin to second-order expertise (i.e. they are often experts on the positions of other philosophers, current trends in the philosophical literature, the history of philosophy, conceptual analysis and so on), they nevertheless lack first-order philosophical expertise (i.e. expertise (...) on philosophical positions themselves such as the nature of mind, causality, normativity and so forth). Throughout the paper, I respond to potential objections. (shrink)

To what extent should we trust our natural instincts about knowledge? The question has special urgency for epistemologists who want to draw evidential support for their theories from certain intuitive epistemic assessments while discounting others as misleading. This paper focuses on the viability of endorsing the legitimacy of Gettier intuitions while resisting the intuitive pull of skepticism – a combination of moves that most mainstream epistemologists find appealing. Awkwardly enough, the “good” Gettier intuitions and the “bad” skeptical intuitions seem to (...) be equally strong. This chapter argues that it is not a coincidence that these two types of intuition register with equal force: they are generated by a common mechanism. However, the input to this mechanism is interestingly different in the two types of case, and different in a way that can support the mainstream view that Gettier cases tell us something about knowledge where skeptical intuitions involve systematic error.

Less discussed than Hume’s skepticism about what grounds there could be for projecting empirical hypotheses is his concern with a skeptical regress that he thought threatened to extinguish any belief when we reflect that our reasoning is not perfect. The root of the problem is the fact that a reflection about our reasoning is itself a piece of reasoning. If each reflection is negative and undermining, does that not give us a diminution of our original belief to nothing? It requires (...) much attention to detail, we argue, to determine whether or not there is a skeptical problem in this neighborhood. Consider that if we subsequently doubt a doubt we had about our reasoning, that would suggest a restoration of some of the force of our original belief. We would then have instead of runaway skepticism an alternating sequence of pieces of skeptical reasoning that cancel each others’ effects on our justification in the original proposition, at least to some degree. We will argue that the outcome of the sequence of reflections Hume is imagining depends on information about a given case that is not known a priori. We conclude this from the fact that under three precise, explanatory, and viable contemporary reconstructions of what this kind of reasoning about reasoning could be like and how it has the potential to affect our original beliefs, a belief-extinguishing regress is not automatic or necessary.

Often philosophers have reason to ask fundamental questions about the aims, methods, nature, or value of their own discipline. When philosophers systematically examine such questions, the resulting work is sometimes referred to as “metaphilosophy.” Metaphilosophy, it should be said, is not a well-established, or clearly demarcated, field of philosophical inquiry like epistemology or the philosophy of art. However, in the late 20th and early 21st centuries there has been a great deal of metaphilosophical work on issues concerning the methodology of (...) philosophy in the analytic tradition. This article focuses on that work. (shrink)

Nāgārjuna, vissuto in India attorno al primo secolo dopo Cristo, è certamente una delle figure più importanti del pensiero buddhista. In una delle sue opere principali, le ‘Strofe sulla via di mezzo ’, egli elabora in modo compiuto la nozione di ‘vuoto’, che diverrà uno dei concetti fondamentali di tutto il buddhismo successivo, dando vita alla ‘scuola del vuoto’, la quale avrà grande fortuna in Tibet, Cina e Giappone. Per vuoto non si intende certo il nulla, bensì l’inconsistenza rivelata dal (...) reale quando considerato alla luce della critica di Nāgārjuna. Tale critica si esplica innanzitutto sul piano del linguaggio, e possiede quindi una evidente dimensione pragmatica. Il ‘vuoto’ nāgārjuniano sarà allora non solo una non-ontologia, ma anche una non-predicazione, che ammetterà però il giudizio, e quindi la determinazione, solo ed esclusivamente dal punto di vista della prassi del dire. Al linguaggio non è richiesto di parlare dell’essere, bensì di testimoniare, attraverso la propria inconsistenza, dell’assoluta coincidenza di essere e non-essere. (shrink)

This is a short essay that presents what I take to be the main questions regarding the epistemology of disagreement.

Philosophers often find themselves in disagreement with contemporary philosophers they know full well to be their epistemic superiors on the topics relevant to the disagreement. This looks epistemically irresponsible. I offer a detailed investigation of this problem of the reflective epistemic renegade. I argue that although in some cases the renegade is not epistemically blameworthy, and the renegade situation is significantly less common than most would think, in a troublesome number of cases in which the situation arises the renegade is (...) blameworthy in her disagreement with recognized epistemic superiors. I also offer some thoughts on what it would mean for philosophical practice for us to refrain from being renegades. Finally, I show how a new kind of radical skepticism emerges from modest theses regarding the renegade. (shrink)

What happens when a psychologist who’s spent the last 30 years developing a method of introspective sampling and a philosopher whose central research project is casting skeptical doubt on the accuracy of introspection write a book together? The result, Hurlburt & Schwitzgebel’s thought-provoking Describing Inner Experience?, is both encouraging and disheartening. Encouraging, because the book is a fine example of fruitful and open-minded interdisciplinary engagement; disheartening, because it makes clear just how difficult it is to justify the accuracy of introspective (...) methods in psychology and philosophy. And since debates in consciousness studies largely turn on fine points of introspective detail, this is no minor methodological stumbling block. (shrink)

Those of us who take skepticism seriously typically have two relevant beliefs: (a) it’s plausible (even if false) that in order to know that I have hands I have to be able to epistemically neutralize, to some significant degree, some skeptical hypotheses, such as the brain-in-a-vat (BIV) one; and (b) it’s also plausible (even if false) that I can’t so neutralize those hypotheses. There is no reason for us to also think (c) that the BIV hypothesis, for instance, is plausible (...) or probably true. In order to take skepticism seriously it’s sufficient to hold (a) and (b); one need not hold (c). Indeed, philosophers who accept (a) and (b) never endorse (c). Show me a philosopher who suspects that he is a brain in a vat and I’ll show you someone who is deranged! That’s one thing that bothers undergraduates in philosophy. They object: why on earth do some philosophers take the BIV hypothesis to pose any threat at all to our beliefs given that those very same philosophers think that there’s no real chance that the BIV hypothesis is true? Sure, the BIV hypothesis is formally inconsistent with my belief that I have hands, so if the former is true then my belief is false. But so what? Why should that bare inconsistency matter so much? Is this strange attitude amongst philosophers the result of some logic fetish infecting the philosophical community? It is sometimes said that the skeptical hypotheses are not only inconsistent with our beliefs but are explanatory of our experiences, which is supposed to make them more of a threat. But students aren’t fooled: although the skeptical hypotheses may attempt to explain why our experience is as it is, it’s the kind of attempt appropriate for science fiction movies that are all special effects and virtually no plot. No one with any sense of reality will take the evil demon hypothesis to be even tenuously explanatory. (shrink)

Philosophy in the West divides into three parts: Analytic Philosophy (AP), Continental Philosophy (CP), and History of Philosophy (HP). But all three parts are in a bad way. AP is sceptical about the claim that philosophy can be a science, and hence is uninterested in the real world. CP is never pursued in a properly theoretical way, and its practice is tailor-made for particular political and ethical conclusions. HP is mostly developed on a regionalist basis: what is studied is determined (...) by the nation or culture to which a philosopher belongs, rather than by the objective value of that philosopher’s work. Progress in philosophy can only be attained by avoiding these pitfalls. (shrink)

I’m going to argue for a set of restricted skeptical results: roughly put, we don’t know that fire engines are red, we don’t know that we sometimes have pains in our lower backs, we don’t know that John Rawls was kind, and we don’t even know that we believe any of those truths. However, people unfamiliar with philosophy and cognitive science do know all those things. The skeptical argument is traditional in form: here’s a skeptical hypothesis; you can’t epistemically neutralize (...) it, you have to be able to neutralize it to know P; so you don’t know P. But the skeptical hypotheses I plug into it are “real, live” scientific-philosophical hypotheses often thought to be actually true, unlike any of the outrageous traditional skeptical hypotheses (e.g., ‘You’re a brain in a vat’). So I call the resulting skepticism Live Skepticism. Notably, the Live Skeptic’s argument goes through even if we adopt the clever anti-skeptical fixes thought up in recent years such as reliabilism, relevant alternatives theory, contextualism, and the rejection of epistemic closure. Furthermore, the scope of Live Skepticism is bizarre: although we don’t know the simple facts noted above, many of us do know that there are black holes and other amazing facts. (shrink)

The preface and chapter 1 of my book Scepticism Comes Alive, 2005 OUP.

When it comes to second-order knowledge, internalists typically contend that when we know that p, we can, by reflecting, directly know that we are knowing it. Gettier considerations are employed to challenge this internalistic contention and to make out a prima facie case for internalistic metaepistemological skepticism, the thesis that no one ever intemalistically knows that one internalistically knows that p. In particular, I argue that at the metaepistemological second-order level, the Gettier problem generates three distinct problems which, taken together, (...) seriously undermine the possibility of anyone possessing second-order internalistic knowledge.

The Socratic Paradox (that only Socrates is wise, and only because only he recognizes our lack of wisdom) is explained, elaborated and defended. His philosophical scepticism is distinguished from others (Pyrrhonian, Cartesian, Humean, Kripkean Wittgenstein, etc.): the doubt concerns our understanding of our beliefs, not our justification for them; the doubt is a posteriori and inductive, not a priori. Post-Socratic philosophy confirms this scepticism: contra-Descartes, our ideas are not transparent to us; contra-Verificationism, no criterion distinguishes sense from nonsense. The import (...) of this scepticism for professional ethicists is examined. (shrink)

Epistemologists have traditionally been concerned with two issues: the justification of particular beliefs or sets of beliefs, and claims to knowledge. I propose to examine the relative import of these questions by comparing the gravity of the threat posed by two sceptics: one who questions the justifiability of our beliefs, and one who doubts our knowledge claims.

The epistemological consequences of paradox are paradoxical. They can be usefully generated by telling a series of once-upon-a-time stories that make various philosophical points, starting out innocent and ending up, well, paradoxical. This is an introduction to my Live Skepticism, defended in Skepticism Comes Alive.
