In this article, I examine al-Ghazālī’s methodological skepticism and its role in establishing foundational knowledge.Despite the considerable scholarly attention given to The Deliverance from Error (al-Munqidh min al-ḍalāl), the foundationalism present in it has received relatively limited investigation. Al-Ghazālī established the foundations of knowledge by taking his methodological skepticism to its logical conclusions. His engagement with the sources of knowledge, namely, taqlīd, sense perception, and self-evident truths form the cornerstone of his skepticism. To understand how (...) al-Ghazālī finds deliverance from his skeptical impasse, and ultimately establish foundational knowledge, the concepts of “divine light” and fiṭra will be dis­cussed. Unlike Greek skepticism, al-Ghazālī’s skepticism was not a denial of the possibility of knowledge about the nature of reality, nor was it a denial of Muslim doctrine, but a methodological approach to establish the foundations of knowledge.

The deduction of categories in the 1781 edition of the Critique of the Pure Reason (A Deduction) has “two sides”—the “objective deduction” and the “subjective deduction”. Kant seems ambivalent about the latter deduction. I treat it as a significant episode of Kant’s thinking about categories that extended from the early 1770s to around 1790. It contains his most detailed answer to the question about the origin of categories that he formulated in the 1772 letter to Marcus Herz. The answer is (...) that categories are generated a priori through a kind of intellectual “epigenesis”. This account leaves unexplained why precisely such and such categories should be generated. While this observation caused Kant to worry about the hypothetical status of the subjective deduction in 1781, he would come to acquiesce in the recognition that the ground of the possibility of categories is itself inscrutable. I call this his “methodological skepticism”. (shrink)

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.

In this book, Henrik Lagerlund offers students, researchers, and advanced general readers the first complete history of what is perhaps the most famous of all philosophical problems: skepticism. As the first of its kind, the book traces the influence of philosophical skepticism from its roots in the Hellenistic schools of Phyrronism and the Middle Academy up to its impact inside and outside of philosophy today. Along the way, it covers skepticism during the Latin, Arabic, and Greek Middle (...) Ages and during the Renaissance before moving on to cover Descartes's methodological skepticism and Pierre Bayle's super-skepticism in the seventeenth century. In the eighteenth century, it deals with Humean skepticism and the anti-skepticism of Reid and Kant, taking care to also include reflections on the connections between idealism and skepticism. The book covers similar themes in a chapter on G.E. Moore and Ludwig Wittgenstein, and then ends its historical overview with a chapter on skepticism in contemporary philosophy. In the final chapter, Lagerlund captures some of skepticism's impact outside of philosophy, highlighting its relation to issues like the replication crisis in science and knowledge resistance.

Function-first approaches illuminate phenomena by investigating their functional roles. I first describe virtues of this approach. By foregrounding normal instances of knowledge, for example, function-first theorising offers a much-needed corrective to epistemology's counterexample-driven momentum towards increasingly byzantine, marginal cases. And epistemic practices are shaped by human limitations, needs, vices, and power relations. These non-ideal, naturalistic forces of embodied sociality form the roots of function-first theorising, which creates a fecund foundation for social epistemology. Secondly, I consider an objection to function-first theorising. (...) The objection holds that function-first approaches lack adjudicatory power. That is, function-first proposals are overly compatible with diverse claims about knowledge, which encourages “just so” speculation. In response to this concern, I advocate methodological pluralism in epistemological theorising. All methods have limitations; researchers must be mindful of those limits and fruitfully combine multiple methods. I illustrate with Hannon's function-first based arguments for “epistemic pragmatism”, which denies that the meaning of “knows” is determined by truth conditions. Finally, I argue that function-first theorising motivates staunch anti-skepticism about knowledge. Practical forces cannot chisel a sharp threshold for how much evidence is required for knowledge. But thinking this supports radical skepticism about knowledge conflates fuzzy thresholds and high ones. (shrink)

This paper discusses a common contemporary characterization of skepticism and skeptical arguments-that their real importance is instrumental, that they “drive progress in philosophy.“ I explore two possible contrasts to the idea that skepticism's significance is thus wholly methodological. First, I recall for the reader a range of views that can be understood as `truth in skepticism' views. These concessive views are those most clearly at odds with the idea that skepticism is false, but instrumentally valuable. (...) Considering the contributions of such `truth in skepticism' theorists, I argue, shows that the good of furthering philosophical progress is partly achieved by the work of those who would reject the `merely methodological' view of skepticism's import. While this shows such a view of skepticism's import to be partially self-effacing, it is not therefore incoherent. Rather, the characterization is revealed to be wedded to particular diagnoses of skepticism, and not independently innocuous or neutral. Second, I discuss the idea that the `merely methodological' characterization of skepticism's import draws a contrast with philosophical positions or theses that are supposed to have practical teeth. Here, I think the danger of acquiescing too readily to this view is that the normative import of skeptical arguments is obscured. At a time when discussions of the value of knowledge are in ascendency, this in particular seems a loss-a route from consideration of skeptical arguments to broader normative questions worth keeping open is rather more obscured than opened up. Any radically revisionary outcome of an encounter with skepticism is less likely, led by such an understanding, just when there is opportunity instead to connect up with broad questions of epistemic value. For these reasons I argue the characterization is not one to too readily, unthinkingly, endorse. (shrink)

Skepticism has always been a part of the history of Western philosophy. If one were to look at current works focusing on the history of skepticism in philosophy, however, one would get the impression that skepticism disappeared from the philosophical landscape after the work of Sextus Empiricus, only to reappear with the methodological skepticism of Descartes. Yet, did skepticism, which had thus been so prevalent in the ancient period, disappear so completely during the middle (...) Ages? The resounding answer that this dissertation proposes to give to this question is no. To that end, the main focus will be on Nicolaus of Autrecourt, a figure in the waning High Middle Ages who revived skepticism within a peculiarly Christian context. In the first three chapters of the dissertation, the skepticism of Nicolaus of Autrecourt will be studied. Starting in the first chapter with a study of Nicolaus's life and the skeptical elements of his correspondence, the second chapter will continue to look for these same skeptical elements in his Exigit ordo, while the third chapter will look for possible influences on Nicolaus's skepticism. The fourth and fifth chapter will present views similar to Nicolaus's in the works of the Muslim thinker al-Ghazali and the more well-known David Hume concerning the skepticism of causal necessity. In the sixth and final chapter, a major difference between the doctrines of Nicolaus and al-Ghazali on the one hand and Hume on the other concerning the issue of miracles will be examined. From this point, a simplified genealogy of skepticism shall be offered, and it will be contended that the skepticisms of Nicolaus and al-Ghazali deserve a place in that genealogy. By allowing Nicolaus's and al-Ghazali's type of skepticism into this genealogy, the main conclusion shall be that skepticism is in fact a double-edged sword that can be used against religion by attempting to destroy the ability of reason to come to any definitive conclusions about God or against atheistic philosophy in leaving room for faith in the omnipotence of God.

Donald Davidson has argued that attention to the necessarily public character of language shows that we cannot be massively mistaken about the world around us, and that consequently skeptical doubts about empirical knowledge are misplaced. The arguments Davidson advances rely on taking as the fundamental methodological standpoint for investigating meaning and related concepts the standpoint of the interpreter of another speaker, on the grounds that it is from the interpreter’s standpoint that we discover what constraints are placed on meaning (...) by the public character of language. In this paper, I argue that although Davidson’s arguments reveal important conceptual connections between meaning and belief on the one hand, and truth and interpretation on the other, they do not show that it is impossible that we are massively mistaken about the external world.

For a variety of reasons, including the common use of deception in psychology experiments, participants often disbelieve experimenters' assertions about important task parameters. This can lead researchers to conclude incorrectly that participants are behaving non- normatively. The problem can be overcome by deriving and testing normative models that do not assume full belief in key task parameters. A real experimental example is discussed.

A central project of traditional epistemology is to address skeptical questions and concerns regarding the rationality or epistemic justification of our empirical beliefs, especially beliefs regarding the external world, with the aim of understanding what makes it possible for such beliefs to have or lack justification, and of determining how much justification we have. A prominent anti-skeptical view in the history of epistemology, a view I shall call classical foundationalism, can be distinguished from other more contemporary versions of foundationalism in (...) part on the basis of two central commitments: (i) the traditional methodological commitment to carry out the project of addressing skepticism “from the armchair,” i.e., on the basis of what can be determined by a posteriori deliverances of introspection and a priori use of reason and reflection, without relying on empirical or scientific research that presupposes the existence of any external world of material objects (including armchairs); and (ii) a substantive commitment to the doctrine of the given, understood roughly as the view that empirical beliefs ultimately depend for their justification on a direct or immediate awareness of reasons to think these beliefs true, reasons simply “given” to us in conscious experience. -/- There has been a recent resurgence of interest in classical or “old-fashioned” varieties of foundationalism, and the debate seems, in some ways, to be repeating itself. Critics object that these attempted resurrections of classical foundationalism are just attempts to square the same old circles.”They argue that there are decisive or clearly sufficient reasons to deny that such a view can be right, let alone that an adequate theory can be developed that is defensible in all its essential details. I think that these critics are either missing the point of the traditional project, misunderstanding classical foundationalism, or exaggerating the severity of the problems they raise. -/- I will show that a number of common arguments against classical foundationalism are not nearly as worrisome as their proponents think. In Chapter 2, I defend classical foundationalism against the Sellarsian dilemma, and provide prima facie support from examples for the availability of foundational empirical beliefs. I then discuss some recent classical foundationalist accounts of the justification of foundational beliefs, argue that these accounts are less than satisfactory, and develop an account of my own. In Chapter 3 I defend classical foundationalism, as a version of internalism, against Bergmann’s recent dilemma for internalism. Finally, in Chapter 4, I take up the issue of skepticism about the external world, and, in closing, the related issue of whether any beliefs about the external world can themselves be empirically foundational.

One of the most basic methods of philosophy is, and has always been, the consideration of counterfactual cases and imaginary scenarios. One purpose of doing so obviously is to test our theories against such counterfactual cases. Although this method is widespread, it is far from being commonly accepted. Especially during the last two decades it has been confronted with criticism ranging from complete dismissal to denying only its critical powers to a cautious defense of the use of thought experiments as (...) counterexamples. One of the strongest criticisms of the method of thought experimentation is "modal skepticism" as explicated and defended by Peter van Inwagen. Van Inwagen argues that the philosopher's notion of logical possibility is confused and that its epistemology is dubious. I argue that van Inwagen's skepticism is unwarranted. There is a sufficiently clear notion of logical possibility and a sufficiently straightforward way of getting to know what is logically possible. In the remainder of the paper I show how that connects with the methodology of thought experimentation in philosophy. (shrink)

The paper defends the view that that a significant part of metaphysics should be understood as conceptual engineering, and explores its epistemological advantages and metaphysical implications. It discusses the challenge raised by moderate modal skepticism, which points out the lack of reliable methods for verifying modal statements through thought experiments. As I argue, a normative stance on metaphysical methodology, understanding it as engaging in conceptual engineering project, justifies the use of this method. By adopting an approach where the method (...) of cases offers reasons for adopting specific normative constraints on concept usage, the method becomes justifiable. Consequently, it can be employed to justify the revision of conceptual schemes and, in turn, validate certain modal claims about entities falling under the scrutinized concepts. The paper explores how this approach can methodologically enrich conceptual engineering-focused perspectives in metaphysics and examines its metaphysical consequences. In particular, it demonstrates that despite the mind-dependency of the method of cases results, it still leaves room for a metaphysically realistic viewpoint. (shrink)

In this paper I consider the plausibility of developing anti-skepticism by framing the question in linguistic terms: instead of asking whether we know, we ask what falls within the extension of the word “know”. I first trace two previous attempts to develop anti-skepticism in this way, from Austin (particularly as presented by Kaplan) and from epistemic contextualism, and I present reasons to think that both approaches are unsuccessful. I then focus on a more recently popular attempt to develop (...) anti-skepticism from the “function-first” approach associated with Craig, which I also show to be problematic. I then argue that the apparent prima facie plausibility of fighting skepticism on linguistic grounds is due to a methodological spill-over from linguistics. Once we recognize this, it becomes clear that debate around skepticism should not be conducted in linguistic terms. (shrink)

Michael Bergmann's Radical Skepticism and Epistemic Intuition develops a response to radical skepticism inspired by commonsense philosophers, such as Reid and Moore. Bergmann argues against radical skepticism on the grounds of its conflicting with strongly-held "epistemic intuitions" about the "epistemic value or goodness” of our particular perceptual, recollective, introspective and a priori beliefs. I press concerns about whether Bergmann's "intuitionist particularist" response can diagnose the source of skepticism, and argue that his methodology turns out to itself (...) be strikingly skeptical.

This paper examines "moderate modal skepticism", a form of skepticism about metaphysical modality defended by Peter van Inwagen in order to blunt the force of certain modal arguments in the philosophy of religion. Van Inwagen’s argument for moderate modal skepticism assumes Yablo's (1993) influential world-based epistemology of possibility. We raise two problems for this epistemology of possibility, which undermine van Inwagen's argument. We then consider how one might motivate moderate modal skepticism by relying on a different (...) epistemology of possibility, which does not face these problems: Williamson’s (2007: ch. 5) counterfactual-based epistemology. Two ways of motivating moderate modal skepticism within that framework are found unpromising. Nevertheless, we also find a way of vindicating an epistemological thesis that, while weaker than moderate modal skepticism, is strong enough to support the methodological moral van Inwagen wishes to draw.

In lieu of an abstract, here is a brief excerpt of the content:Cartesian Skepticism from Bare PossibilityRobert WachbritIn making his case for skepticism, Peter Unger offers the following exotic case as one which “conforms to a familiar, if not often explicitly artic-ulated pattern or form” of skeptical reasoning: 1 imagine that there is an evil scientist who deceives subjects into falsely believing that there are rocks. Living in a world bereft of rocks, he induces belief in their existence (...) using electrodes implanted into the appropriate parts of the subjects’ brai ns, protoplasm, or systems through which he sends patterns of electrical impulses in accord with his deceptive designs. Unger then offers the following argument, which is supposed to instantiate the pattern or form of this kind of skeptical reasoning:If you know that there are rocks, then you can know that there is no such scientist doing this to you. But no one can ever know that there is no evil scientist who is, by means of electrodes, deceiving him into falsely believing there to be rocks. So... you never know that there are rocks. But of course we have chosen our person, and the matter of there being rocks, quite arbitrarily, and this argument... may be generalized to cover any external matter at all. From this, we may conclude... that nobody knows anything about the external world. 2After presenting this case and articulating its form, Unger claims that “this argument is the same in form as the ‘evil demon’ argument in Descartes’s [End Page 109] Meditations; it is but a more modern, scientific counter-part, with its domain of application confined to matters concerning the external world.” He then proceeds to describe Descartes’s argument as “the most compelling sceptical argument the phil osophical literature has to offer,” calling it in fact “the classical argument for scepticism.” 3These claims may seem a little bit surprising; for it is not obvious, even from the most careful attention to the text, that what is written about the evil demon in the First Meditation constitutes a skeptical argument at all, and the scholarly literature is generally, and perhaps surprisingly, quite confusing about just what is going on at the end of the First Meditation. Further, rather than being exceedingly compelling as Unger thinks, arguments of this form are not only assiduously avoided by Descarte s during his descent into skepticism but are in fact, as I shall argue with some help from Descartes, weak and considerably less compelling than the kind of skeptical challenges Descartes actually offers.My purpose in this paper, then, is to make two related points, one historical and the other philosophical. First, I will try to demonstrate, on the basis of both textual and critical evidence, that Descartes was not offering a (further and final) skeptica l argument when he invented his demon. I will try to exhibit some of the confusions in the scholarly literature about the text of the last three paragraphs of the First Meditation and, by so doing, support Gouhier’s position that the idea of the demon “ha s no metaphysical significance; it is purely a methodological artifice which permits doubt to continue....” 4 Second, I will show that embodied in Descartes’s rejection of this kind of skeptical reasoning is the very reason for its weakness, a weakness that should prevent it from being considered, as Unger considers it, the classical form of skeptical argument. The inventions of the First Meditation still exercise considerable hold on our philosophical imaginations. I hope to show that, at least as far as the demon is concerned, Descartes would have been surprised at some of the most conventional and entrenched scholarly interpretations given his use of it and not at all sympathetic to its employment in a skeptical argument. Lest the demon seem an old and tired subject of philosophical scrutiny, let me beg the reader’s indulgence by promising both a deeper than usual look into the text of the end of the First Meditation and some significant conclusions about Cartesian skepticism that are hardly commonplace and thus neither old nor tired. [End Page 110]I. The Textual EvidenceThe demon makes its first appearance in the last paragraph of the... (shrink)

Part I (Skepticism) contains analyses of the basic varieties of ethical skepticism and culminates in the idea that the refutation of ethical skepticism--or, what is the same thing, the discovery of the rational basis of morality--consists of a proof of the factual thesis that there exists in human beings a common underivative moral self that consists of an innate normative-practical source (or principle-spring) of human moral judgment and behavior. Part 2 (The Basis of Morality) develops the methodology (...) for establishing this factual thesis and develops as well an argument employing this methodology that actually establishes it. This argument is to the effect that nature through the process of evolution-by-natural-selection built into us humans the following principle as the rational basis of morality: We ought to act only in those ways whose universal performance is both possible and consistent with the rational self-interest of every member of our species.

:In this essay, I critically engage with a methodological approach in contemporary political theory — unconstrained utopianism — which holds that we can only determine how we should live by first giving an account of the principles that would govern society if people were perfectly morally motivated. I provide reasons for being skeptical of this claim. To begin with I query the robustness of the principles unconstrained utopianism purportedly delivers. While the method can be understood as offering existence proofs, (...) because we can devise other situations in which morally flawless decision making would unearth alternative sets of principles, I argue that such proofs tell us surprisingly little about how we should live in general. Drawing on this point, I contend that normative models that wish away certain phenomena that are uncontroversially central to any account of politics cannot plausibly claim to tell us how we should live in political society. I conclude by offering a more positive sketch of why avoiding this brand of utopianism might not represent a problematic capitulation to the morally nonideal and suggest that theorizing in light of certain constraints may be a precondition of good normative theorizing itself.

This paper examines the work of Nāgārjuna as interpreted by later Madhyamaka tradition, including the Tibetan Buddhist Tsongkhapa (1357–1419). It situates Madhyamaka skepticism in the context of Buddhist philosophy, Indian philosophy more generally, and Western equivalents. Find it broadly akin to Pyrrhonism, it argues that Madhyamaka skepticism still differs from its Greek equivalents in fundamental methodologies. Focusing on key hermeneutical principles like the two truths and those motivating the Svātantrika/Prāsaṅgika schism (i.e., whether followers of Nāgārjuna should offer positive (...) arguments or should proceed on a purely “negative” basis), it argues that the Svātantrika commitment to mere conventional practice is robust and allows for a skepticism consistent with the scientific practices we must take seriously in the modern world. These findings are put forth as an illustration of what the Western tradition might gain by better understanding of non-Western philosophy. (shrink)

Havstad and Smith (2019) argue that Lakatos’ “methodology of scientific research programs” (MSRP) is a promising philosophical framework for explaining the perceived empirical success of the hypothesis that birds are maniraptoran theropod dinosaurs, and the perceived empirical failures or stagnation of alternatives to that hypothesis. These conclusions are rejected: Havstad and Smith’s account of the alternative “research programs” inadequately characterizes criticism of the hypothesis that birds are maniraptoran theropods and they neither offer sufficient modifications to MSRP to correct its known (...) difficulties in deriving logically or empirically satisfactory criteria for the assessment and preferential selection of “research programs” from historiographical data, nor proposals to mitigate its tendency to promote confirmation bias and dogmatism. Independent flight loss, an important problem in systematic ornithology with implications for the origin of birds, provides a supplementary demonstration of how the application of MSRP in the present context would tend systematically to mislead investigations of the evolutionary history of birds by promoting an uncritical perspective. Given these difficulties, MSRP is an unacceptable philosophical framework for evaluating alternative hypotheses for the origin of birds. (shrink)

It is argued that the debate regarding radical scepticism needs to be conducted in the light of a value-theoretic methodological constraint. It is further shown that such a methodological constraint raises some uncomfortable problems for the main anti-sceptical proposals in the literature.

In the preceding pages, Husserl's objections to the content of Descartes'Meditations on First Philosophy have been reconstructed over the line ofargument in that work. The tone of his interpretation moved from ambivalence to outfight rejection. Husserl's ambivalence manifested itself intwo of the three meditations to which he pays significant attention. We sawthe much heralded methodological strategy of the First Meditation, uponclose examination, is not endorsed by Husserl, that he finds reason toprotest against the content of each individual skeptical argument (...) and seesthere in general a subjectivistic doctrine of consciousness already at work.Nevertheless, Husserl clearly wanted to preserve the essential intent of theCartesian method of doubt if not its letter, namely, the move toward callinginto question naive presuppositions about the world, raising the possibilityof its non-existence, thereby resuscitating sheer wonder about the world,and rendering it problematic in its relation to subjectivity. Historically, thisstrategy has precedent in the ancient Greek sophists, who, however unintentionally, Husserl claims were the first to manifest a transcendental im-pulse. Moving into the Second Meditation and the so-called discovery ofthe ego cogito, we found a stronger ambivalence on Husserl's part. Whileapplauding Descartes for uncovering the truth that lay hidden at the basis ofskepticism, the subsequent interpretation of the ego as soul and substantialentity clouds this inchoative insight into pure transcendental subjectivity.By the Third Meditation Husserl's ambivalence moved to out right rejection. There are a number of reasons why: the circularity of Descartes'theological theory of evidence ; the epistemologicalcommitment to a subjectivistic theory of consciousness; hisScheinprobleme along with the assumption of an objectivein-itself forever remote from intuition; the ontological commitment to twofinite substances; and the attempt to deductively redress the cognitiveschism created by these commitments through appeal to the principle ofcausality and the goodness of God. All these gave Husserl decisive occa-sion to take leave of the Cartesian path of meditation.A further reason why Husserl's meditations consistently break off in theThird Meditation is suggested by noticing the textual moment whereHusserl's silence begins. It is that moment where Descartes dips into theScholastic tradition for the concepts of objective and formal reality in orderto prove the existence of God. The problem, I suggest, is that here Des-cartes insufferably compromises his radicalness. More specifically, with theconcepts of objective and formal reality Descartes installs on the metaphysi-cal level the distinction between image and original already operative allalong in the earlier Meditations. Now, through the concepts of objective andformal reality, the image /original distinction is given ex-planatory power and raised to a truth so evident as to be beyond the reach ofmethodic doubt. The fact that this distinction is employed to deduce theexistence of God is not so much the phenomenological offense as themetaphysical naivete of positing a formal reality, an in itself, to account forthe very matters in question.

This book argues that external world skepticism is false for straightforward reasons. To make this case it develops and defends a neglected methodological approach involving a distinctive process of first-person reflection. We begin within the practices, procedures, and commitments of ordinary life and science. We then seek some reason to think skepticism true, carefully scrutinizing all the most important arguments. Finding no reason to think it true and decisive reasons to think it false, we reject it. As (...) the book shows, this is a fully satisfactory refutation. No epistemological theorizing is needed. The book begins by exploring and defending this method in seminal works of G. E. Moore and J. L. Austin. Turning to contemporary epistemology, it asks why we shouldn't appeal to considerations about the world when responding to skeptical argumentation. No good reason is found, despite exploration of a wide range of central issues in recent epistemology. To the contrary, perfectly ordinary examples indicate that it is correct to reject the skeptical scenarios - the dreaming worry, Descartes' evil demon, the brain-in-a-vat - by appealing to things we know about the world. Likewise, considerations about sensory perception do not provide any reason to think our evidence excludes considerations about the world. Along the way, methodological lessons are drawn from consideration of the most important skeptical arguments in the contemporary literature. The book concludes by defending the satisfactoriness of its approach. What emerges is a new understanding of what philosophical illumination might look like in relation to core epistemological issues. (shrink)

Austin is not much in fashion these days. In Austin’s Way with Skepticism, Mark Kaplan swims against the current, arguing that Austin still has much to teach us about how to do epistemology. Methodologically, Austin’s insistence on fidelity to ordinary ways of talking about knowledge is a non-negotiable constraint on epistemological theorizing. Substantively, Austin has important things to say about knowledge. But while I am fully in accord with the spirit of Kaplan’s enterprise, I take Austin to occupy a (...) more radical position: that getting the linguistic facts straight should lead us to call into question the very idea of a theory of knowledge, at least as ‘theory of knowledge’ has traditionally been understood.

Controversies have always characterized philosophy as expression of its typical critical attitude that depends on the complexity of the fundamental philosophical issues. Traditionally these discrepancies regarded the answers given to certain questions and, therefore, the content of the opposite doctrines, as all legitimately belonging to philosophy. With modernity the determination of the correct method of thinking becomes the necessary precondition for philosophizing and represents the core of the philosophical activity itself. As a consequence people adopting a certain method of thinking (...) often qualify as non-philosophical the discourse of those who do not belong to their methodological school, independently of the content of the doctrine they defend. This dominance of the methodological concern, on the contrary, has produced the discovery and deepening of several “thinking methods,” whose plurality must be considered a wealth and not a reason for skepticism, since it can offer to philosophy the tools for better coping with the increasing complexity of its fundamental issues.

Lately, several commentators have argued that there are significant differences between ancient and modern skepticism. For example, it has been argued that ancient skeptics disavow belief, whereas the moderns disavow only knowledge. It has also been argued that the scope of ancient skepticism is considerably less radical than that of modern skepticism: unlike the moderns, the ancients do not question whether they have bodies or whether there is an external world furnished with the sorts of objects we (...) generally take there to be. They do not suspend judgment as to whether, for example, honey exists, but only as to whether it is sweet. One explanation that has been given for the allegedly modest scope of ancient skepticism is its practical concern: ancient skepticism is a way of life, one that is supposed to secure the skeptic’s happiness. But, according to Myles Burnyeat, “[s]uch being his primary concern, he cannot doubt in a completely general way his ability to act in the world.” Modern skepticism, by contrast, is said to be “a strictly methodological affair,” with the result that, unlike ancient skeptics, modern ones can act in the face of radical skepticism.

THE HYPERBOLICAL DOUBT OF THE FIRST MEDITATION is often taken for the epitome of skepticism. Thus Myles Burnyeat, in his 1982 paper, “Idealism and Greek Philosophy: What Descartes Saw and Berkeley Missed,” argues that Descartes goes further than the ancient skeptics in doubting the existence of his own body—a given of everyday experience they never doubted. Nor was “the existence of the external world,” which was imperiled by the agency of the evil demon and has been recurrently questioned ever (...) since, a major subject for doubt in the skeptical tradition. Moreover, Burnyeat explains, Descartes was able to carry skepticism to this extreme because his doubt was merely methodological: it left his provisional rules of conduct intact while he was searching theoretically for a truth that would itself be in the first instance theoretical. Of course we should not forget that eventually, Descartes believed, the truth he was on the way to discovering would have excellent consequences for practice also, namely, in medicine, mechanics, and morality. Meantime, however, Burnyeat is certainly correct in maintaining that Cartesian doubt was indeed insulated against practice—as Hume’s doubt would eventually be also, confined as it was to his closet. So Descartes, and other modern skeptics after him, could be as skeptical as you like, as skeptical as any one can be. The ancient skeptics could not go that far, Burnyeat argues, because it was daily life they were concerned with, not some purely theoretical gambit. Like the philosophers of other Hellenistic schools—though differently, of course—they were seeking peace of mind, and they wanted to eliminate those unnecessary questions about hidden things—causes or “ultimate” realities—that served to obstruct the state of mind they called “tranquillity.” Merely methodologically, doubt can become much more radical, and it is that radicalization that, with the help of his demon, Descartes accomplishes.

This paper provides a study of the three most famous skeptical thinkers of classical India, examining both their commonalities and unique differences. Adepts of the controversial debate methodology called vitaṇḍā, “negative debate,” these thinkers manage to challenge the very possibility of knowledge, while espousing (at least nominal) allegiance to distinct schools of thought. They also pass negative judgement on the possibility of certainty while appealing to rational persuasion. This paper explores these paradoxes and possible contradictions, with a culminating reflection of (...) the role of the “two truths,” ultimate vs. everyday perspectives. (shrink)

The focus of this chapter will be Kant’s understanding of Hume, and its impact on Kant’s critical philosophy. Contrary to the traditional reading of this relationship, which focuses on Kant’s (admittedly real) dissatisfaction with Hume’s account of causation, my discussion will focus on broader issues of philosophical methodology. Following a number of recent interpreters, I will argue that Kant sees Hume as raising, in a particularly forceful fashion, a ‘demarcation challenge’ concerning how to distinguish the legitimate use of reason in (...) (say) natural scientific contexts from the illegitimate use of it in (say) dogmatic metaphysics. I will then go on to argue that Kant sees Hume’s tendency to slide into more radical forms of skepticism as a symptom of his failure to provide a systematic or principled account of this distinction. This failure, I argue, can be traced (according to Kant) to Hume’s impoverished, non-hylomorphic account of our faculties – which both robs Hume of the materials necessary to construct a genuinely systematic philosophy as Kant understands this, and makes it impossible for Hume to clearly conceive of what Kant calls ‘Formal Idealism.’ In this way, the failings of Hume’s account of causation are (for Kant) symptoms of more fundamental limitations within Hume’s philosophy. I close by briefly discussing the similarities between Hume and Kant’s understanding of the relationship between, first, philosophical methodology and, second, the nature of our faculties. (shrink)

Modern science faces a series of problems that undermine confidence in its reliability. To solve these problems, we must reflect on what makes science work and what leads it astray. This book is about Science, its strengths and weaknesses. The papers that scientists write form a vast resource of evidence and theory that is doubling about every ten years, along with the number of scientists. The size of this resource makes it hard for it to be used effectively by scientists, (...) and along with this are growing concerns about its integrity and reliability. This book looks at the scientific method, as currently applied and as understood philosophically by scientists, the social structure of science, and the structure of scientific communication through journals. It includes case studies of controversies, and looks at how fields develop over time. (shrink)

The theory of knowledge has two sides - epistemology and a bridge to join them: that a belief is justified if and only if obtained by appropriate use of an adequate organon - a principle of theoretical epistemology requiring an organon or manual of practical methodology. Such organon justification is internalist. (How could one ever miss one's source for it?) But it leads briskly to skepticism on pain of regress or circularity - or so it is argued in section (...) 1. In section 2 we consider the epistemology embodied in the Socratic elenchus, which provides a new angle on how methodology relates to epistemology and to science and metaphysics. Thus are we made to face once again the organon account of justification: our internalist bridge principle. That account proves in section 3 to be a special case ,of a more general argumentative account of justification, which in turn agrees with intuitions so powerful as to be enshrined already in our dictionaries. Good rhetoric suggests therefore that 'justification' and its cognates be yielded to the argumentative account; in which case justification must likely fall from its status as principal concept of epistemology. Justification is hence unlikely to be all that is required in general for knowledge, nor is it likely to be what is always required in any premises of use to justify anything. That way, apparently, lies regress or circularity. Better to demote justification to the status of one way for a belief to be appropriate or apt for knowledge, while allowing other ways not dependent on already attained justification: perception, perhaps, or introspection, or memory.

This paper situates the critical attitude undergirding Ágnes Heller’s theory of modernity by elucidating her conceptualization of its ‘undialectical dialectics’ relative to the dialectical philosophies of Kant and Hegel. For Heller, the methodological commitments orienting a philosopher’s decision on how to conceptualize the dynamics of modernity are not merely theoretical but also ethico-practical, for they attempt to overcome the duality of life and spirit in the singular personality. For the denizens of contemporary modernity – who recognize contingency inhering in (...) their institutions – and for philosophers – who recognize the fallibility of their theoretical claims – a form of skepticism is warranted. By engaging with the work of György Márkus, Heller attempts to evince a notion of ‘normative skepticism’ that may exhibit both a critical attitude appropriate to conceiving modernity as ‘undialectical dialectics’ and to attenuate for the threat of ‘existential failure’ in the choice of oneself as a philosopher.

In this paper I begin by examining Fogelin’s account of deep disagreement. My contention is that this account is so deeply flawed as to cast doubt on the possibility that such deep disagreements actually happen. Nevertheless, I contend that the notion of deep disagreement itself is a useful theoretical foil for thinking about argumentation. The second part of this paper makes this case by showing how thinking about deep disagreements from the perspective of rhetoric, Walton-style argumentation theory, computation, and normative (...) pragmatics can all yield insights that are useful no matter what one’s orientation within the study of argument. Thus, I conclude that deep disagreement –even if it were to turn out that there are no real-world occurrences of it to which we can point–is useful for theorists of argumentation. In this wise, deep disagreement poses a theoretical challenge for argumentation theory not unlike that posed by radical skepticism for traditional epistemology. (shrink)

Intuition serves a variety of roles in contemporary philosophy. This paper provides a historical discussion of the revival of intuition in the 1970s, untangling some of the ways that intuition has been used and offering some suggestions concerning its proper place in philosophical investigation. Contrary to some interpretations of the results of experimental philosophy, it is argued that generalized skepticism with respect to intuition is unwarranted. Intuition can continue to play an important role as part of a methodologically conservative (...) stance towards philosophical investigation. I argue that methodological conservatism should be sharply distinguished from the process of evaluating individual propositions. Nevertheless, intuition is not always a reliable guide to truth and experimental philosophy can serve a vital ameliorative role in determining the scope and limits of our intuitive competence with respect to various areas of inquiry.

This dissertation offers a philosophical account of Zhuangzi's thought, particularly of his skepticism and the background assumptions on which he advocates skepticism as a way of living. Before presenting my own views, I consider several other lines of interpretation, both to raise theoretical and textual issues and to situate my own work in the context of existing scholarship. In the first two chapters I translate and analyze selected Neo-Daoist and early Buddhist commentaries in order to emphasize the influence (...) these two distinct and often conflicting traditions have exercised over modern receptions of the text. The next five chapters examine modern interpretations of Zhuangzi as an advocate of personal freedom, mystical insight, relativism, skillful living, and spontaneity, respectively, looking at the works of Fung, Creel, Maspero, Yearley, Hansen, Wu, Ivanhoe, and Graham, among others. In the final two chapters I offer my own interpretation, which is to understand Zhuangzi as responding to a distinctive philosophical problem, that of choosing between competing conceptual schemes, particularly as instantiated in different methodologies and terminologies. He is skeptical of the possibility of establishing a scheme as correct. And yet the simple fact that he wrote anything down is evidence of his belief that skepticism itself offers the best possible solution to the otherwise irresolvable problem. Close attention to the text reveals the basis of this belief in a cluster of assumptions which I refer to collectively as Zhuangzi's "naturalism." Briefly put, Zhuangzi thinks that the good life is the natural life and that people live naturally when they respond to their situations with the open-mindedness and flexibility that skepticism brings. Both the strengths and the limitations of this position are highlighted by a consideration of the objection raised against Zhuangzi by the Confucian philosopher Xunzi, who argues that the good life depends on the cultivation of certain desires which are not in us originally and consequently which no amount of open-mindedness can be counted upon to reveal. The appendix collects the available historical material concerning the text itself and how it came down to us in its present form. (shrink)

This article provides an account of the Enlightenment dispute over hermeneutical skepticism with particular reference to the idea of hermeneutical probability in the philosophical work of Christian August Crusius. The essay sheds new light on the hermeneutical issues addressed in the philosophical school of the so-called Thomasians based mainly in Leipzig in the first half of the eighteenth century. The paper deals with Crusius’ wide-ranging efforts to cope with the uncertain character of most parts of human knowledge and his (...) attempts to construct a workable theory of hermeneutical probability. This raises points of central interest relating to probabilism in the methodology of textual interpretation and connects Crusius to contemporary discussions of hermeneutical skepticism. (shrink)

The thought experiment is a seemingly indispensable tool in the armchair philosopher’s toolbox. One wonders, for example, how philosophers could come to think that justified true belief isn’t knowledge, that reference isn’t determined by an expression’s associated description, or that moral responsibility doesn’t require the ability to do otherwise, without the use of thought experiments. But even if thought experiments play an integral role in philosophical methodology, their legitimacy is at least initially puzzling: one would think that significant knowledge of (...) the world requires extensive empirical investigation. But since thought experiments are done from the armchair, how can they tell us about the world? -/- A standard account of the nature and utility of thought experiments provides an answer to this question, and in a way that fits naturally with a standard picture of the nature of the facts philosophers investigate: Philosophers are about the business of investigating the essences of things and kinds. But a thing’s essential and accidental properties are modal properties. Thus, one can discern a thing’s essence by discovering its modal profile. But if so, then thought experiments are naturally suited as tools for the armchair philosopher. For thought experiments shed light on modal facts. Therefore, since philosophers investigate essences, facts about essence are modal facts, and the thought experiment is one of the few tools they have for discerning such facts, thought experiments play a legitimate and indispensable role in philosophical methodology. In my dissertation, I argue that the standard account of the nature and utility of thought experiments is inadequate, and sketch a more promising account. -/- First, I argue that our knowledge of possibility is restricted to the relatively humdrum. And if so, then since the standard account ties the utility of thought experiments to our knowledge of possibility, too many thought experiments will be ruled out as useless, which raises serious concerns about the significance, and perhaps even the legitimacy, of armchair philosophy. Thus, there is pressure for armchair philosophers to reject the standard account. -/- Second, I sketch an alternative picture of the nature of facts philosophers investigate – one that’s more fine-grained than the standard modal-profile picture. Relatedly, I sketch a correspondingly fine-grained semantics for claims about such facts. This alternative picture underwrites the legitimacy of a hitherto underappreciated sort of thought experiment, which I call the non-modal thought experiment. Such thought experiments shed light on facts about the world that are more fine-grained than what can be discerned by merely examining their modal profiles. I argue that non-modal thought experiments often succeed at just the points where the more familiar modal thought experiments fail, and thus that the two are naturally suited to complement one another in the philosopher’s practice. -/- Finally, I exploit the points mentioned above to sketch an account of the variety and utility of thought experiments that’s much more nuanced than that of the standard account. I then illustrate some of its virtues by indicating its ability to account for a wide range of epistemically forceful thought experiments – both humdrum and exotic –, and by demonstrating how it can be used to make progress in debates that have reached a stalemate due to conflicting modal intuitions. -/- .

In this work, the first overview of the German Idealism that is both conceptual and methodological, Paul W. Franks offers a philosophical reconstruction that is...

According to some critics, traditional armchair philosophical methodology relies in an illicit way on intuitions. But the particular structure of the critique is not often carefully articulated—a significant omission, since some of the critics’ arguments for skepticism about philosophy threaten to generalize to skepticism in general. More recently, some experimentalist critics have attempted to articulate a critique that is especially tailored to affect traditional methods, without generalizing too widely. Such critiques are more reasonable, and more worthy of serious (...) consideration, than are blunter critiques that generalize far too widely. I argue that a careful (empirical!) examination of extant philosophical practices shows that traditional philosophical methods can meet these more reasonable challenges. (shrink)

This critical study of Anthony Brueckner’s essay collection on skepticism emphasizes interconnections between the various essays. In particular, it considers Brueckner’s discussion of transcendental anti-skeptical arguments from the theses of anti-individualism and privileged self-knowledge. Finally, some overarching methodological lessons are drawn.

I offer a novel reading in this dissertation of René Descartes’s (1596–1650) skepticism in his work Meditations on First Philosophy (1641–1642). I specifically aim to answer the following problem: How is Descartes’s skepticism to be read in accordance with the rest of his philosophy? This problem can be divided into two more general questions in Descartes scholarship: How is skepticism utilized in the Meditations, and what are its intentions and relation to the preceding philosophical tradition? -/- I (...) approach the topic from both a historical and a text-based analysis, combining textual and contextual research. I examine Descartes’s skepticism against two main traditions in the historical analysis: philosophical skepticism and Aristotelian Scholasticism. I argue that skepticism in the Meditations is intended to oppose and upheave both Scholasticism and skepticism. The intended results of the work are not merely epistemological but also metaphysical and even ethical. Furthermore, these ambitions cannot be neatly distinguished but merge into each other. -/- The third historical context against which the skeptical meditations are examined is the literary genre of meditative exercises, particularly from the 1500–1600’s, which, while religiously and spiritually oriented, likewise provided the practitioner with an enlightened understanding of self-knowledge and their cognitive place in the world on the way to closer spiritual proximity to God. I argue by this reading that the skepticism of the Meditations is an attentive, meditational cognitive exercise that is not merely instrumental and methodological but is to have a genuine and serious (psychologically real) effect on our thinking. The skeptical meditation is not simply a theoretical thought experiment but is to be seriously practiced as a transformative process of reorienting one’s cognitive framework to discover truth, certainty, and a way to a happy, tranquil, and virtuous life. -/- I offer a close reading in the textual analysis of the first three meditations of the Meditations. I argue that the meditative skepticism employed in the work does not reject the previous beliefs but suspends judgment on them, withdrawing assent until further evidence can be found. I introduce a new term into Descartes scholarship in this analysis, based on the terminology of ancient skepticism: Cartesian epochē (gr. epochē, suspension, withdrawal). Instead of rejecting previous beliefs or assenting to the probably false, the skeptical procedure of the Meditations is argued to emulate in important ways the suspension of judgment on equally balanced reasons in ancient Pyrrhonian skepticism. Novel interpretations are presented along the way of the will’s freedom, of the First Meditation’s skeptical scenarios, of the cogito, and of the vindication of metaphysical certainty, as well as a clarification of the Cartesian Circle problem. -/- Reinterpreting the relation of Descartes’s skepticism to the preceding historical and literary traditions leads to a new look at the skeptical method itself. Presenting a new interpretation of skepticism in the Meditations leads at the same time to a new look at its relation to the historical context. The two research questions are, then, intrinsically tied together. -/- My focus in the study is on the Meditations, but I also reference and discuss Descartes’s other philosophical works, as well as his correspondence, when necessary.

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.

This paper considers the theoretical and methodological origins of Marx's beliefs and attitudes towards classical moral theories and then their implications for two basic questions: (1) In what way, if any, was Marx suspicious and dismissive of classical moral theories (e.g., utilitarianism or Kantianism), and (2) what sort of moral theory can a proponent of Marx's moral views support? Here it is argued that there is a clear sense in which Marx would not have been automatically suspicious of moral (...) ideas, conceptions, discourse and the rest. But there is an equally clear sense in which he was. It is in the latter respect that Marx’s views must be explicated in terms of his theory of historical development, and it is only here that the full richness and impact of Marx’s views on moral philosophy can be understood and appreciated.

Studies on so-called Change Blindness and Inattentional Blindness have been taken to establish the claim that conscious perception of a stimulus requires the attentional processing of that stimulus. One might contend, against this claim, that the evidence only shows attention to be necessary for the subject to have access to the contents of conscious perception and not for conscious perception itself. This “Methodological Argument” is gaining ground among philosophers who work on attention and consciousness, such as Christopher Mole. I (...) find that, without the supporting evidence of inaccessible consciousness, this argument collapses into an indefensible form of inductive parsimony. The Methodological Argument is thus shown to be unsuccessful when used against the claim that attention is required for conscious perception, though I suggest that it may be successful against the more ambitious claim that attention is necessary for all conscious experience.
