We will be in a better position to evaluate some important skeptical theses if we first investigate two questions about justified suspended judgment. One question is this: when, if ever, does one justified suspension confer justification on another suspension? and the other is this: what is the structure of justified suspension? the goal of this essay is to make headway at answering these questions. After surveying the four main views about the non-normative nature of suspended judgment (...) and offering a taxonomy of the epistemic principles that might govern which suspended judgments are justified, I will isolate five important principles that might govern which suspended judgments are justified. I will call these suspension-to-suspension principles. I will then evaluate these principles by the lights of each of the four views about what suspensions are. I close by drawing some conclusions about the prospects for skepticism, the structure of justified suspended judgment, and the importance of theorizing about justified suspended judgment. (shrink)

O propósito deste artigo é mostrar como podem ser desenvolvidas explicações robustas de justificação e de certeza no interior do infinitismo. Primeiro, eu explico como a concepção infinitista de justificação epistêmica difere das concepções fundacionista e coerentista. Em segundo lugar, explico como o infinitista pode oferecer uma solução ao problema do regresso epistêmico. Em terceiro lugar, explico como o infinitismo, per se, é compatível com as teorias daqueles que sustentam 1) que o conhecimento requer certeza e que uma tal forma (...) superior de conhecimento é possível, bem como com as daqueles que rejeitam algum ou ambos os conjuntos em 1). Em outras palavras, o infinitismo nem endossa, nem rejeita o ceticismo, tomando-se essa tese como sendo aquela segundo a qual nós não possuímos conhecimento naquelas situações que nos parecem cognoscíveis. PALAVRAS-CHAVE – Certeza. Coerentismo. Fundacionismo. Infinitismo. Pirronismo. Regresso epistêmico. ABSTRACT The purpose of the paper is to show how robust accounts of justification and certainty can be developed within infinitism. First, I explain how the infinitist conception of epistemic justification differs from both the foundationalist and coherentist conceptions. Second, I explain how the infinitist can provide a solution to the epistemic regress problem. Third, I explain how infinitism, per se, is compatible with both the views of those who hold 1) that knowledge requires certainty and that such high-grade knowledge is possible as well as those who deny either or both conjuncts in 1). In other words, infinitism neither endorses nor rejects skepticism, taking that view to mean that we do not have knowledge in those areas commonly thought to be within our ken. KEY WORDS – Certainty. Coherentism. Foundationalism. Infinitism. Pyrrhonism. Epistemic regress. (shrink)

Throughout the history of philosophy, skepticism has posed one of the central challenges of epistemology. Opponents of skepticism--including externalists, contextualists, foundationalists, and coherentists--have focussed largely on one particular variety of skepticism, often called Cartesian or Academic skepticism, which makes the radical claim that nobody can know anything. However, this version of skepticism is something of a straw man, since virtually no philosopher endorses this radical skeptical claim. The only skeptical view that has been truly held--by Sextus, Montaigne, Hume, Wittgenstein, and, (...) most recently, Robert Fogelin--has been Pyrrohnian skepticism. Pyrrhonian skeptics do not assert Cartesian skepticism, but neither do they deny it. The Pyrrhonian skeptics' doubts run so deep that they suspend belief even about Cartesian skepticism and its denial. Nonetheless, some Pyrrhonians argue that they can still hold "common beliefs of everyday life" and can even claim to know some truths in an everyday way. This edited volume presents previously unpublished articles on this subject by a strikingly impressive group of philosophers, who engage with both historical and contemporary versions of Pyrrhonian skepticism. Among them are Gisela Striker, Janet Broughton, Don Garrett, Ken Winkler, Hans Sluga, Ernest Sosa, Michael Williams, Barry Stroud, Robert Fogelin, and Roy Sorensen. This volume is thematically unified and will interest a broad spectrum of scholars in epistemology and the history of philosophy. (shrink)

This paper argues for a completely universal scepticism, according to which no beliefs at all are justified to the least degree. The argument starts with a version of the Agrippan trilemma, according to which, if we accept that a belief is justified, we must choose between foundationalism, coherentism of a particular sort, and an infinite regress of justified beliefs. Each of these theories is given a careful specification in terms of the relationship of “justifiedness in p depending on justifiedness in (...) q”. It is then argued that no beliefs – not even beliefs about phenomenal experiences – are foundational in the required way. Both coherentism and infinitism are untenable, since, since they face various objections, most significantly the objection that acceptance of either would commit one to allowing that all beliefs were justified. Because the three possible accounts of justificational structure all fail radically, it is concluded that no beliefs are justified. (shrink)

Skepticism in epistemology refers to the supposedly irrational attitude of suspending judgment about all beliefs, particularly those taken for granted. The skeptical attitude presses philosophy to investigate the conditions under which knowledge and justification rather than accidental truths can be arrived at. In the first chapter, we will investigate how to construct a form of radical skepticism known as Pyrrhonian skepticism; we will see how Agrippa's Trilemma builds three ways of skeptical defense to object to three possible conditions in (...) the structuring of epistemic justification. In the second chapter, we will examine infinitism as a possible answer to the trilemma, as well as the conceptual bases that make possible the existence of this possible solution to the skeptical challenge. In the third, the main objection to infinitism known as the finite mind problem will be analyzed. In the fourth chapter, we will look at an alternative formulation of the trilemma, as well as the challenges this approach poses to the anti-skeptical response. (shrink)

This article discusses contemporary response to the epistemic regress problem or Agrippa's trilemma. The epistemic regress problem is considered the most crucial in the entire theory of knowledge and it is a major concern for many contemporary epistemologists. However, only two of the three alternative solutions have been developed in any detail, foundationalism and coherentism. Infinitism was not seriously considered as a solution because of the finite-mind objection. This article also provides a brief evaluation of foundationalism, emergent coherentism, and infinitism.

Semantic holists view what one's terms mean as function of all of one's usage. Holists will thus be coherentists about semantic justification: showing that one's usage of a term is semantically justified involves showing how it coheres with the rest of one's usage. Semantic atomists, by contrast, understand semantic justification in a foundationalist fashion. Saul Kripke has, on Wittgenstein's behalf, famously argued for a type of skepticism about meaning and semantic justification. However, Kripke's argument has bite only if one understands (...) semantic justification in foundationalist terms. Consequently, Kripke's arguments lead not to a type of skepticism about meaning, but rather to the conclusion that one should be a coherentist about semantic justification, and thus a holist about semantic facts.

This paper formally explores the common ground between mild versions of epistemological coherentism and infinitism; it proposes—and argues for—a hybrid, coherentist–infinitist account of epistemic justification. First, the epistemological regress argument and its relation to the classical taxonomy regarding epistemic justification—of foundationalism, infinitism and coherentism—is reviewed. We then recall recent results proving that an influential argument against infinite regresses of justification, which alleges their incoherence on account of probabilistic inconsistency, cannot be maintained. Furthermore, we prove that the Principle of Inferential Justification (...) has rather unwelcome consequences—formally resembling the Sorites paradox—as soon as it is iterated and combined with a natural Bayesian perspective on probabilistic inferences. We conclude that strong versions of foundationalism and infinitism should be abandoned. Positively, we provide a rough sketch for a graded formal coherence notion, according to which infinite regresses of epistemic justification will often have more than a minimal degree of coherence.

Foundationalists distinguish basic from nonbasic beliefs. At a first approximation, to say that a belief of a person is basic is to say that it is epistemically justified and it owes its justification to something other than her other beliefs, where “belief” refers to the mental state that goes by that name. To say that a belief of a person is nonbasic is to say that it is epistemically justified and not basic. Two theses constitute Foundationalism: (a) Minimality: There are (...) some basic beliefs, and (b) Exclusivity: If there are any nonbasic beliefs, that is solely because they (ultimately) owe their justification to some basic belief. Proponents of Minimality but not Exclusivity endorse Minimal Foundationalism. Proponents of Exclusivity but not Minimality endorse either Epistemic Nihilism, the view that there are no justified beliefs, or some non-foundationalist epistemology such as Coherentism or Infinitism. In this essay I aim to characterize the notion of a basic belief more precisely and to assess some arguments for and against Foundationalism. In the process, I hope to exhibit the resilience and attractiveness of Foundationalism. (shrink)

In Metaepistemology and Skepticism (Rowman & Littlefield:\n1995), Richard Fumerton defends foundationalism. As part of\nthe defense he rejects infinitism--the view that holds that\nthe solution to the problem of the regress of justificatory\nreasons is that the reasons are infinitely many and\nnonrepeating. I examine some of those arguments and attempt\nto show that they are not really telling against (at least\nsome versions of) infinitism.

The Continuum Companion to Epistemology offers the definitive guide to a key area of contemporary philosophy. The book covers all the fundamental questions asked by epistemology - areas that have continued to attract interest historically as well as topics that have emerged more recently as active areas of research. Sixteen specially commissioned essays from an international team of experts reveal where important work continues to be done in the area and, most valuably, the exciting new directions the field is taking. (...) The Companion explores issues pertaining to foundationalism, coherentism, infinitism, reliabilism, proper functionalism, evidentialism, skepticism, contextualism, epistemic relativism, intuition and experience. Featuring a series of indispensable research tools, including an A to Z of key terms and concepts, a chronology, a detailed list of resources and a fully annotated bibliography, this is the essential reference tool for anyone working in contemporary epistemology.

Many have thought that it is impossible to rationally persuade an external world skeptic that we have knowledge of the external world. This paper aims to show how this could be done. I argue, while appealing only to premises that a skeptic could accept, that it is not rational to believe external world skepticism, because doing so commits one to more extreme forms of skepticism in a way that is self-undermining. In particular, the external world skeptic is ultimately committed to (...) believing a proposition P while believing that she shouldn’t believe P, an irrational combination of beliefs. Suspending judgment on skepticism is also problematic, for similar reasons; and, I argue, rational dilemmas are not possible; so, we should believe that skepticism is false. (shrink)

Foundationalist, Coherentist, Skeptic etc., have all been united in one respect--all accept epistemic justification cannot result from an unending, and non-repeating, chain of reasons. Peter Klein has recently challenged this minimal consensus with a defense of what he calls "Infinitism"--the position that justification can result from such a regress. Klein provides surprisingly convincing responses to most of the common objections to Infinitism, but I will argue that he fails to address a venerable metaphysical concern about a certain type of regress. (...) My conclusion will be that until Klein answers these metaphysical worries he will not have restored Infinitism as a viable option in epistemology. (shrink)

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.

Infinitism in Epistemology. This article provides an overview of infinitism in epistemology. Infinitism is a family of views in epistemology about the structure of knowledge and epistemic justification. It contrasts naturally with coherentism and foundationalism. All three views agree that knowledge or justification requires an appropriately structured chain of reasons. What form may such a […].

As the Pyrrhonians made clear, reasons that adequately justify beliefs can have only three possible structures: foundationalism, coherentism, and infinitism. Infinitism—the view that adequate reasons for our beliefs are infinite and non-repeating—has never been developed carefully, much less advocated. In this paper, I will argue that only infinitism can satisfy two intuitively plausible constraints on good reasoning: the avoidance of circular reasoning and the avoidance of arbitrariness. Further, I will argue that infinitism requires serious, but salutary, revisions in our evaluation (...) of the power of reasoning. Thus, reasoning can not provide a basis for assenting to a proposition—where to assent to a proposition, p, means to believe that we know that p. A non-dogmatic form of provisional justification will be sketched. Finally, the best objections to infinitism, including those posed by the Pyrrhonians, will be shown (at least provisionally!) to be inadequate. (shrink)

Infinitism is often presented as a rival to foundationalism and coherentism as available answers to the epistemic regress problem. The most prominent contemporary defense of infinitism, due to Peter Klein, rests on the notion that an agent can perpetually amplify the justification for her belief insofar as they are able to iteratively answer an interlocutor’s questions why the proffered grounds for their belief should count as providing justification for that belief. We show that this argument does not offer any basis (...) for preferring infinitism over foundationalism and coherentism, because those views are able to accommodate the insight that justification for a belief can be continually amplified. Klein’s argument for infinitism thus falls short of its aspirations of proving that infinitism qua rival of foundationalism and coherentism is the most credible solution to the epistemic regress problem. (shrink)

In this paper I examine, and reject, one of the chief philosophical arguments that purports to show that Pyrrhonian Skepticism is incompatible with possessing any beliefs. That argument, first put forward by Jonathan Barnes and since accepted by many philosophers, focuses on the skeptic's resolute suspension of judgment concerning one philosophical issue, namely whether criteria of truth exist. In short, the argument holds that, because skeptics suspend judgment whether criteria of truth exist, they have no basis on which (...) to discriminate between their impressions, which is a necessary condition for belief formation. I show that this argument fails because it misunderstands both the nature of criteria of truth and the epistemic consequences of suspending judgment concerning their existence. Thus, I clear the main philosophical obstacle preventing an interpretation of Pyrrhonism as consistent with possessing beliefs (associated most famously with Michael Frede). (shrink)

I will compare Lehrer’s anti-skeptical strategy from a coherentist point of view with the anti-skeptical strategy of the Mooreans. I will argue that there are strong similarities between them: neither can present a persuasive argument to the skeptic and both face the problem of easy knowledge in one way or another. However, both can offer a complete and self-explanatory explanation of knowledge although Mooreanism can offer the more natural one. Hence, one has good reasons to prefer Mooreanism to Lehrer’s anti-skeptical (...) approach, if one does not prefer coherentism to foundationalism for other reasons. (shrink)

Infinitism, in contrast to foundationalism and coherentism, claims that justification in any proposition requires the availability of an infinite chain of propositional reasons, each providing a justificatory reason for its successor in the chain. Both infinitists and some critics of the theory have at times noted the possibility that the theory may have sceptical consequences for doxastic justification. It is argued here that, for reasons that appear not to have been previously appreciated, sceptical results very definitely do follow from infinitism. (...) On one construal of infinitism, this constitutes a reductio of the theory. On an alternative construal, infinitists may embrace the sceptical conclusion, but in doing so, will take on all the problems that scepticism faces. (shrink)

Once upon a time, coherentism was the dominant response to the regress problem in epistemology, but in recent decades the view has fallen into disrepute: now almost everyone is a foundationalist (with a few infinitists sprinkled here and there). In this paper, I sketch a new way of thinking about coherentism, and show how it avoids many of the problems often thought fatal for the view, including the isolation objection, worries over circularity, and concerns that the concept of coherence is (...) too vague or metaphorical for serious theoretical use. The key to my approach is to take a familiar tool from discussions of the regress problem -- namely, directed graphs depicting the support relations between beliefs -- and to use that tool in a more sophisticated manner than it is standardly employed. (shrink)

Consider the following process of epistemic justification: proposition $E_{0}$ is made probable by $E_{1}$ which in turn is made probable by $E_{2}$ , which is made probable by $E_{3}$ , and so on. Can this process go on indefinitely? Foundationalists, coherentists, and sceptics claim that it cannot. I argue that it can: there are many infinite regresses of probabilistic reasoning that can be completed. This leads to a new form of epistemic infinitism.

The article discusses infinitism, the view that a belief is justified for a subject only if she possesses an infinite chain of available reasons for that belief. In its most recent and sophisticated version, the view allegedly escapes the problems that trouble its main competitors, foundationalism and coherentism, while avoiding the traditional objections which relegated it to a marginal place. The article argues that despite these improvements, sophisticated versions of infinitism face a pressing problem, viz. they are unable to appropriately (...) articulate propositional and doxastic justification. (shrink)

This chapter has two goals: to motivate the foundationalist solution to the regress problem and to defend it against arguments from Sellars, BonJour and Klein. Both the motivation and the defence of foundationalism raise larger questions about the relationship between foundationalism and access internalism. I argue that foundationalism is not in conflict with access internalism, despite influential arguments to the contrary, and that access internalism in fact supplies a theoretical motivation for foundationalism. I conclude that foundationalism and access internalism form (...) a coherent and well-motivated package. (shrink)

There are some tantalizing suggestions that Pyrrhonian skepticism has its roots in ancient India. Of them, the most important is Diogenes Laertius’s report that Pyrrho accompanied Alexander to India, where he was deeply impressed by the character of the “naked sophists” he encountered (DL IX 61). Influenced by these gymnosophists, Pyrrho is said to have adopted the practices of suspending judgment on matters of belief and cultivating an indifferent composure amid the vicissitudes of ordinary life. Such conduct, and the (...) attitudes that it embodied, became inspirations to later skeptical thinkers. It is a fact that practices of the sort attributed to Pyrrho are richly evident in a number of ancient Indian philosophical and ascetic movements. On this basis, attempts have been made to determine the identity of these gymnosophists and, further, to pinpoint the dialectical tropes within Pyrrhonism that may have their basis in Indian thought. But despite these attempts, and in the absence of any new discoveries, these suggestions will likely remain just that. The paucity of the historical data and the problematic nature of the data itself prevent us from reconstructing a solid bridge between ancient India and Greek skepticism that may serve as the basis of robust historical theorizing. Classical India does, however, lay claim to a sophisticated and diverse culture of epistemological reflection, which includes a number of innovative skeptical thinkers deserving study on their own merits. This chapter is meant to provide such a study, or perhaps more accurately, a prolegomena for such. After some initial ground-laying, I will discuss three leading Indian skeptics and situate them historically and conceptually within the network of competing schools that comprise classical Indian philosophy. They are Nāgārjuna (c. 150 CE), the founder of Madhyamaka Buddhism, Jayarāśi (c. 800), associated with the Indian materialist tradition, and Śrīharṣa (c. 1150), a thinker connected to the school of Nondual (Advaita) Vedānta.

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.

In his ?Nihilism, Skepticism, and Philosophical Method,? Paul Thagard claims that my critique of his The Brain and the Meaning of Life misapprehends his argument. According to Thagard, the critique wrongly assumes that the book offers foundationalist justifications for Thagard's views whereas, in fact, the justifications his book presents are coherentist. In my response, I show that the claim that my critique depends on foundationalist assumptions is ungrounded. Moreover, the appeal to coherentist rather than foundationalist justifications does not salvage Thagard's (...) discussion, since it is problematic under both foundationalism and coherentism. Thagard does not show that the anti-nihilist position he supports is more coherent than the nihilist position he rejects, and brain research does not justify his claims about the meaning of life under coherentism any more than under foundationalism.

In this chapter, we examine different views of the structure of justification, including foundationalism, infinitism, and coherentism. We investigate how well or poorly they seem to do in responding to the regress problem, accommodating a robust connection between justification and truth, and getting the contours of justification right—i.e., making justification neither too easy nor too hard to get. We end by briefly discussing some challenges to finding a single sense of “foundational belief” defining the debate.

Recently, metaphysical coherentism has been propounded as an alternative to metaphysical foundationalism and infinitism. The view replaces the picture of reality as a hierarchy of levels with that of a network of objects or facts standing in symmetric or, more generally, cyclic relations of metaphysical dependence. This paper defends the orthodox picture of a well-founded hierarchy against the claimed superiority of coherentism. First, it will be argued that alleged theoretical advantages of coherentism do not hold up to scrutiny. Secondly, examples (...) that are claimed to support coherentism are either misdescribed as involving metaphysical interdependence, or foundationalist treatments fare at least as good and often better than coherentist interpretations. Thirdly, a similar diagnosis applies to a recently proposed coherentist interpretation of quantum entanglement. The more general diagnosis is that claims of metaphysical dependence are convincing only if there is a detailed account of how one item metaphysically explains another. While foundationalists can resort to various specific explanatory relations, coherentism seems to be incapable of providing detailed explanations. (shrink)

This paper is an examination of modest foundationalism in relation to some important criteria of epistemic dependence. The paper distinguishes between causal and epistemic dependence and indicates how each might be related to reasons. Four kinds of reasons are also distinguished: reasons to believe, reasons one has for believing, reasons for which one believes, and reasons why one believes. In the light of all these distinctions, epistemic dependence is contrasted with defeasibility, and it is argued that modest foundationalism is not (...) committed to criteria of epistemic dependence on which foundational beliefs are indefeasible. Modest foundationalism is contrasted with coherentism and is shown to be hospitable to a causal criterion of epistemic dependence, compatible with reliabilism, and neutral with respect to skepticism.

Many philosophers have challenged the problem of skepticism. I argue that none of them successfully dispute the system established by Sextus Empiricus. But not just that; the main thesis proposed is that this kind of skepticism is unsolvable. I maintain that there are two fundamental strategies in Sextus' Outlines of Phyrrhonism. One of them is that the basic description of skepticism has a paradoxical character. The other focuses on the Five Modes of Agrippa that comprise a system of dialectical moves (...) for suspending judgment. The modes have, as a system, the capacity to reposition in any circumstance, so it is impossible to justify to the skeptic why he needs to abandon his skepticism. I explain, in brief, why the most important objections to skepticism do not solve this challenge. In opposition to common view, I argue that Sextus' phyrrhonism is practicable, coherent and consistent. Although there is no possible solution to skepticism, there is at least a general way to answer it without contradiction, infinite regression or becoming a skeptic. (shrink)

In this paper I will argue how Descartes in the First and Second Meditation of the Meditations uses a very clear suspension of judgments or assent that in many ways resembles the epoché of the ancient skepticism, especially that of pyrrhonistic variant. First I show how the pyrrhonistic epoché works and what purpose it was used. After that I show how this Cartesian epoché both resembles and differs from the ancient epoché. My main argument is that Descartes, when using the (...) method of doubt, doesn’t really dismiss or abandon earlier knowledge or beliefs, as he is sometimes been viewed, but more likely doesn’t take any stance in them, suspending his judgment on the existence of the outside-world. I base my argument both on my reading of Meditations and the “as it were sensing” -interpretation of Descartes’ use of method of doubt by John Carriero. (shrink)

In Outlines of Skeptical-Dogmatism, Mark Walker argues for Skeptical-Dogmatism about philosophical views—i.e., he argues that we should disbelieve most philosophical views. Walker argues for Skeptical-Dogmatism over both Dogmatism and Skepticism. In response, I defend Skepticism—i.e., the view that we should neither believe nor disbelieve most philosophical views. I argue that Walker’s arguments overlook some of the most plausible forms of philosophical Skepticism where the Skeptic suspends judgment about most disputed philosophical views without assigning a credence of 0.5 to those (...) views. In doing so, I argue that suspension of judgment is the default justified doxastic attitude—i.e., the doxastic attitude one is epistemically justified in adopting absent any reason to do otherwise. I also champion Skepticism by offering modified versions of some of Walker’s thought experiments, posing challenges for Skeptical-Dogmatism, and arguing that Skepticism and Skeptical-Dogmatism share some common benefits.

It is not uncommon in the history of science and philosophy to encounter crucial experiments or crucial objections the truth-value of which we are ignorant, that is, about which we suspend judgment. Should we ignore such objections? Contrary to widespread practice, I show that in and only in some circumstances they should not be ignored, for the epistemically rational doxastic attitude is to suspend judgment also about the hypothesis that the objection targets. In other words, suspension of (...) class='Hi'>judgment “propagates” from the crucial objection to the hypothesis. In this paper I study under which conditions this phenomenon occurs, and discuss its significance for the topics of skepticism, scientific realism, and peer disagreement. (shrink)

ABSTRACT Friedrich Nietzsche offers different opinions of the ancient Skeptics. On certain occasions, he praises them as philosophers of intellectual integrity, because they constantly question dogma and continue to inquire (ζητϵῖν) into the truth. He insists, however, that it is indispensable for every individual to adopt her own perspective in specific conditions, rather than suspend judgment as the Skeptics do. On other occasions, Nietzsche criticizes the ancient Skeptics because they separate their academic investigations from their philosophy of life and (...) only comply with conventions or apparent phenomena observed through sensations. Furthermore, he ridicules their ultimate goal – tranquility of mind (ἀταραξία) – as a product of feeble exhaustion. He himself is ready to embrace torments of life as part of the will to power. Although some similarities can be traced between Nietzsche and the ancient Skeptics, Nietzsche is more consistent in connecting his theoretical investigation and his philosophy as a way of life.

In this article, I tackle a heretofore unnoticed difficulty with the application of Pyrrhonian scepticism to science. Sceptics can suspend belief regarding a dogmatic proposition only by setting up opposing arguments for and against that proposition. Since Sextus provides arguments exclusively against particular geometrical definitions in Adversus Mathematicos III, commentators have argued that Sextus’ method is not scepticism, but negative dogmatism. However, commentators have overlooked the fact that arguments in favour of particular geometrical definitions were absent in ancient geometry, and (...) hence unavailable to Sextus. While this might explain why they are also absent from Sextus’ text, I survey and evaluate various strategies to supply arguments in support of particular geometrical definitions. (shrink)

In his Reflective Knowledge, Ernest Sosa offers a theory of knowledge, broadly virtue-theoretic in character, that is meant to transcend simple ways of contrasting "internalist" with "externalist" or "foundationalist" with "coherentist" approaches to knowledge and justification. Getting beyond such simplifications, Sosa thinks, is the key to finding an exit from "the Pyrrhonian Problematic": the ancient and profound skeptical problem concerning the apparent impossibility of validating the reliability of our basic epistemic faculties and procedures in a way that escapes vicious circularity. (...) Central to Sosa's anti-skeptical strategy is the claim that there are two kinds of knowledge. His thought is that animal knowledge, which can be understood in purely reliabilist terms, can ground justified trust in the reliability of our basic cognitive faculties, thus elevating us to the level of reflective knowledge. I offer a sketch of an alternative approach, linking knowledge and justification with epistemic accountability and responsible belief-management, which casts doubt on the idea that "animal" knowledge is knowledge properly so-called. However, it turns out that this approach is close in spirit to Sosa's. I suggest that the differences between us may rest on a disagreement over the possibility of providing a direct answer to the Pyrrhonian challenge. (shrink)

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

The central claim of the paper is, roughly, that the fact that it looks to somebody as if p is a defeasibly a priori reason for assuming that p (and vice versa), for any person, even for the perceiver himself. As a preparation, it outlines a doxastic conception suitable to explicate this claim and explains how to analyse dispositions within this conception. Since an observable p has the disposition to look as if p, this analysis generalizes to the central claim (...) which is then argued to be at the bottom of coherentism. Thus, the defense of the claim supports coherentism as opposed to foundationalism and at the same time provides an answer to skepticism about the external world. (shrink)

In this paper, I consider a form of skepticism that has a permissive conclusion, according to which we are rationally permitted to suspend judgment in an area, or to have beliefs in that area. I argue that such a form of skepticism is resistant to some traditional strategies of refutation. It also carries a benefit, namely that it increases voluntary control over doxastic states by introducing options, and therefore greater freedom, into the realm of belief. I argue that intellectual (...) preferences and dispositions provide decisive reasons that can settle our doxastic states in such cases. (shrink)

This essay argues that the Pyrrhonian regress argument presupposes a Prior Grounding conception of justification. This is contrasted with a Default and Challenge structure, which leads to a contextualist picture of justification. Contextualism is said to incorporate the best features of its traditionalist rivals — foundationalism and coherentism — and also to avoid skepticism. It is argued that we should not ask which conception is really true, but instead give up epistemological realism.

An objection that has been raised to the conciliatory stance on the epistemic significance of peer disagreement known as the Equal Weight View is that it is self-defeating, self-undermining, or self-refuting. The proponent of that view claims that equal weight should be given to all the parties to a peer dispute. Hence, if one of his epistemic peers defends the opposite view, he is required to give equal weight to the two rival views, thereby undermining his confidence in the correctness (...) of the Equal Weight View. It seems that the same objection could be leveled against those who claim to suspend judgment in the face of pervasive unresolvable disagreements, as do the Pyrrhonian skeptics. In this paper, I explore the kind of response to the objection that could be offered from a neo-Pyrrhonian perspective, with the aim of better understanding the intriguing character of Pyrrhonian skepticism.

This article seeks to state, first, what traditionally has been assumed must be the case in order for an infinite epistemic regress to arise. It identifies three assumptions. Next it discusses Jeanne Peijnenburg's and David Atkinson's setting up of their argument for the claim that some infinite epistemic regresses can actually be completed and hence that, in addition to foundationalism, coherentism, and infinitism, there is yet another solution (if only a partial one) to the traditional epistemic regress problem. The article (...) argues that Peijnenburg and Atkinson fail to address the traditional regress problem, as they don't adopt all of the three assumptions that underlie the traditional regress problem. It also points to a problem in the notion of making probable that Peijnenburg and Atkinson use in their account of justification. (shrink)

Andrew Cling presents a new version of the epistemic regress problem, and argues that intuitionist foundationalism, social contextualism, holistic coherentism, and infinitism fail to solve it. Cling’s discussion is quite instructive, and deserving of careful consideration. But, I argue, Cling’s discussion is not in all respects decisive. I argue that Cling’s dilemma argument against holistic coherentism fails.

The fundamental debate in contemporary epistemology has been between foundationalists, coherentists, and contextualists. The parties in the debate generally contend that we have knowledge, that having knowledge requires justified belief, and that justified belief consists either in being rationally inferable from some special set of propositions, in cohering in a special way with other beliefs accepted by the subject, or in bearing some special relation to a context in which they are formed or the subject is situated. In this book (...) Elgin opposes views of these kinds and defends a different sort of epistemological theory. Unlike most epistemologists, her theory is not concerned with knowledge; it is concerned with “tenable opinion.” In her view, actual knowledge is more than one can hope for in most cognitive endeavors.

As we trace a chain of reasoning backward, it must ultimately do one of four things: (i) end in an unjustified belief, (ii) continue infinitely, (iii) form a circle, or (iv) end in an immediately justified basic belief. This article defends positism—the view that, in certain circumstances, type-(i) chains can justify us in holding their target beliefs. One of the assumptions that generates the epistemic regress problem is: (A) Person S is mediately justified in believing p iff (1) S has (...) a doxastic reason q for p and (2) S is justified in believing q. Assumption (A) presupposes that reasoning is only justification transmitting, not justification generating. The article rejects (A) and argues that, in certain circumstances, reasoning itself is justification generating, even if that from which one is reasoning is not itself justified. It concludes by comparing positism with its infinitist, coherentist, and foundationalist rivals, acknowledging what is right about these other views. (shrink)
