History: Skepticism

Schulze's Aenesidemus, without its lengthy appendix. -/- Excerpts of the appendix which follows this letter have been translated into English by George di Giovanni in Between Kant and Hegel, eds.

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.

In this paper, I offer a reconstruction of Ghazālī's encounter with scepticism in the Deliverance from Error. For Ghazālī, I argue, radical scepticism about the possibility of knowledge ensues from intellectualist assumptions about the nature of justification. On the reading that I will propose, Ghazālī holds that foundational knowledge can only be justified via actions that lead to transformative experiences.

A Touch of Doubt traces the theme of touch in the evolution of skepticism through Platonism, German idealism, Continental philosophy and psychoanalysis. Haptic Scepticism, the field of ethics emerging from this study, explores the grasp-ability of contradiction. Contradiction is a haptic marvel. We can cup it in our palms, press it against our lips, dip our toes into its coolness, and, if we are not careful, we may even burn ourselves on its surface.

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.

In middle to late Byzantium, one finds dogmatic-style sceptical arguments employed against human reason in relation to divine revelation, where revelation becomes the sole criterion of certain truth in contrast to reason. This argumentative strategy originates in early Christian authors, especially Clement of Alexandria (c. 150–215 CE) and Gregory Nazianzen (c. 329–390 CE), who maintain that revelation is the only domain of knowledge where certainty is possible. Given this, one finds two striking variations of this sceptical approach: a “mild” variant (...) (represented by Clement), where knowledge derived from human reason admits partial access to truths manifested in revelation, if imperfect; and a “strict” variant (represented by Gregory), where knowledge derived from human reason does not admit any access to truths in revelation. This paper analyzes the three Byzantines, Nicholas of Methone (d. 1160/66 CE), Theodore Metochites (1270–1320 CE), and Gregory Palamas (1296–1357/59 CE), who each display certain tendencies toward these two “poles” in their respective epistemological positions on knowledge through reason and faith.

This essay provides an interpretation of Hume’s “two definitions” of causation. It argues that the two definitions of causation must be interpreted in terms of Hume’s fundamental ontological distinction between perceptions and (material) objects. Central to Hume’s position on this subject is the claim that, while there is a natural tendency to suppose that there exist (metaphysical) causal powers in objects themselves, this is a product of our failure to distinguish perceptions and objects. Properly understood, our idea of causation involves (...) no suggestion that there is anything more to causation among objects themselves than constant conjunction. A new appendix is added, discussing the relevance of this interpretation to the recent debate concerning Hume’s “causal realism.” -/- [The original of this article was published in HUME STUDIES 10 (1984), 1 - 25, with corrections added separately in the following issue.].

Peter Fosl's new monograph offers a bold reading of Hume as a "radical," "coherent," and "hybrid" skeptic, who draws influence from both the Pyrrhonian and Academic skeptical traditions. I press some concerns about whether Fosl's reading of Hume can accommodate his scientific ambitions.

We offer a novel interpretation of the argumentative role that Meditation IV plays within the whole of the Meditations. This new interpretation clarifies several otherwise head-scratching claims that Descartes makes about Meditation IV, and it fully exonerates the Fourth Meditation from either raising or exacerbating Descartes’ circularity problems.

This paper offers a new interpretation of the young Spinoza’s method of distinguishing the true ideas from the false, which shows that his answer to the sceptic is not a failure. This method combines analysis and synthesis as follows: if we can say of the object of an idea which simple things underlie it, how it can be constructed out of simple elements, and what properties it has after it has been produced, doubt concerning the object simply makes no sense. (...) The paper also suggests a way in which this methodology connects to the ontology of the Ethics. (shrink)

Descartes’s meditator thinks that if she does not know the existence of God, she cannot be fully certain of anything. This statement seems to contradict the cogito, according to which the existence of I is indubitable and therefore certain. Cannot an atheist be certain that he exists? Atheistic knowledge has been discussed almost exclusively in relation to mathematics, and the more interesting question of the atheist’s certainty of his existence has not received the attention it deserves. By examining the question (...) of atheistic knowledge in relation to the cogito, I articulate the advantage Descartes sees in having knowledge of God. I challenge a long-held reading of the cogito where “I exist” is the first full certainty and argue that while atheistic cogito is more certain than atheistic knowledge in mathematics, it cannot be a starting point for lasting and stable science, because science requires knowing the existence of the non-deceiving God.

Descartes’ demon is a deceiver: the demon makes things appear to you other than as they really are. However, as Descartes famously pointed out in the Second Meditation, not all knowledge is imperilled by this kind of deception. You still know you are a thinking thing. Perhaps, though, there is a more virulent demon in epistemic hell, one from which none of our knowledge is safe. Jonathan Schaffer thinks so. The “Debasing Demon” he imagines threatens knowledge not via the truth (...) condition on knowledge, but via the basing condition. This demon can cause any belief to seem like it’s held on a good basis, when it’s really held on a bad basis. Several recent critics, Conee, Ballantyne & Evans ) grant Schaffer the possibility of such a debasing demon, and argue that the skeptical conclusion doesn’t follow. By contrast, we argue that on any plausible account of the epistemic basing relation, the “debasing demon” is impossible. Our argument for why this is so gestures, more generally, to the importance of avoiding common traps by embracing mistaken assumptions about what it takes for a belief to be based on a reason.

_ Source: _Page Count 25 This is a pre-print. Please cite only the revised published version. This paper presents an original, ambitious, truth-directed transcendental argument for the existence of an ‘external world’. It begins with a double-headed starting-point: Stroud’s own remarks on the necessary conditions of language in general, and Hegel’s critique of the “fear of error.” The paper argues that the sceptical challenge requires a particular critical concept of thought as that which may diverge from reality, and that this (...) concept is possible only through reflection on situations of error, in which how things are thought to be diverges from how things really are with independent items in an objective world. The existence of such a world is therefore a necessary condition of the possibility of scepticism: such scepticism is therefore false. I defend the argument against objections from Stroud’s sceptic and others. Drawing on Heidegger, the paper concludes by indicating that the chain of necessary conditions includes practical engagement with the world. (shrink)

A review of Bernard Will's "Believing Weird Things".

Sample (2015) argues that scientists ought not to believe that their theories are true because they cannot fulfill the epistemic obligation to take the diachronic perspective on their theories. I reply that Sample’s argument imposes an inordinately heavy epistemic obligation on scientists, and that it spells doom not only for scientific theories but also for observational beliefs and philosophical ideas that Samples endorses. I also delineate what I take to be a reasonable epistemic obligation for scientists. In sum, philosophers ought (...) to impose on scientists only an epistemic standard that they are willing to impose on themselves. (shrink)

En este artículo reconstruyo y analizo las respuestas de los escépticos académicos a la objeción de apraxia. Esta objeción afirma que el escepticismo es una doctrina imposible de practicar puesto que sus tesis conducen a la apraxia, esta es, un estado de privación o imposibilidad de acción. Las respuestas a la objeción se dividen en dos clases. La primera prueba que el asentimiento no es una condición necesaria para realizar acciones, por lo que la recomendación escéptica de suspender global y (...) permanentemente el asentimiento no conduciría a la apraxia. La segunda prueba que es posible deliberar y orientar racionalmente nuestras acciones sin impresiones aprehensivas, por lo que la tesis escéptica de que no existen impresiones aprehensivas tampoco conduciría a la apraxia. Tras unas breves consideraciones generales, en la primera parte de este artículo presento las respuestas de Arcesilao y en la segunda parte las repuestas de Carnéades. (shrink)

In the Refutation of Idealism, Kant aims to defeat the Cartesian radical skeptical hypothesis that empirical reality might not exist and we cannot have knowledge of it. Kant intends to demonstrate that conscious experience presupposes direct experience of empirical reality. This paper presents new challenges to the conclusions Kant reaches in the Refutation. Kant’s argument turns on the claim that the past must exist, and my challenges concern the possibility that there is no past.

This is a defense of Pyrrhonian skepticism against the charge that the suspension of judgment based on equipollence is vitiated by the assent given to the equipollence in question. The apparent conflict has a conceptual side as well as a practical side, examined here as separate challenges with a section devoted to each. The conceptual challenge is that the skeptical transition from an equipollence of arguments to a suspension of judgment is undermined either by a logical contradiction or by an (...) epistemic inconsistency, perhaps by both, because the determination and affirmation of equipollence is itself a judgment of sorts, one that is not suspended. The practical challenge is that, independently of any conceptual confusion or contradiction, suspending judgment in reaction to equipollence evinces doxastic commitment to equipollence, if only because human beings are not capable of making assessments requiring rational determination without believing the corresponding premises and conclusions to be true. The two analytic sections addressing these challenges are preceded by two prefatory sections, one laying out the epistemic process, the other reviewing the evidentiary context. The response from the conceptual perspective is that the suspension of judgment based on equipollence is not a reasoned conclusion adopted as the truth of the matter but a natural reaction to an impression left by the apparently equal weight of opposing arguments. The response from the practical perspective is that the acknowledgment of equipollence is not just an affirmation of the equal weight of arguments but also an admission of inability to decide, suggesting that any assent, express or implied, is thrust upon the Pyrrhonist in a state of epistemic paralysis affecting the will and the intellect on the matter being investigated. This just leaves a deep disagreement, if any, regarding whether equipollence is an inference based on discursive activity or an impression coming from passive receptivity. But this, even if resolved in favor of the critic (which it need not and ought not be), is not the same as confusion or inconsistency on the part of the Pyrrhonist, the demonstration of which is the primary aim of this paper.

En este artículo argumento que, pese al llamado “escepticismo cartesiano”, el significado y alcance de la refutación cartesiana del escéptico y del ateo pueden comprenderse a la luz de tres hitos metafísicos. En la primera sección examino de qué forma este filósofo emplea argumentos escépticos como método, no como fin. Tal como enfatizo, el cogito es el punto en que la duda hiperbólica debe detenerse. Luego, en la segunda sección, discuto por qué Descartes es contrario al fideísmo. Debido a que (...) este se relaciona con el escepticismo, y con la imposibilidad de probar la existencia de Dios, Descartes prueba que Él existe. Sostengo, en la sección final, que Dios es garante de la certeza epistemológica, incluso en el caso de las ideas claras y distintas, cuya confiabilidad pareciera en peligro debido a la hipótesis escéptica del genio maligno. Según el francés, entonces, probar que Dios existe es necesario para garantizar el conocimiento cierto, y es base para inferir la existencia del mundo externo. Los tres hitos, entonces, parecen suficientes para delimitar el sentido y alcance del llamado escepticismo cartesiano. (shrink)

This paper assesses both the practical and the epistemic value of Pyrrhonism as this stance is described in Sextus Empiricus’s extant writings. It first explores whether the Pyrrhonist’s suspension of judgment and undisturbedness make us behave in a moral or immoral way, and whether they allow us to attain those goals that would make it possible to live well. It then examines whether the Pyrrhonist’s suspension of judgment makes it possible to reach the epistemic goals of attaining truth and avoiding (...) error. It finally considers whether the results of the previous analyses show that Pyrrhonism is of no philosophical interest to a contemporary audience. (shrink)

I argue that some of the most prominent interpretations of Reid's response to skepticism marginalize a crucial aspect of his thought: namely, that our common sense beliefs meet whatever normative standards of rationality the skeptic might fairly demand of them. This should be seen as supplementary to reliabilist or proper functionalist interpretations of Reid, which often ignore this half of the story. I also show how Reid defends the rationality of believing first principles by appealing to their naturalness and irresistibility. (...) The resulting interpretation supplies Reid with a more satisfying and formidable response to the skeptic than interpretations currently offer. (shrink)

In the Essay Concerning Human Understanding, Locke insists that all knowledge consists in perception of the agreement or disagreement of ideas. However, he also insists that knowledge extends to outer reality, claiming that perception yields ‘sensitive knowledge’ of the existence of outer objects. Some scholars have argued that Locke did not really mean to restrict knowledge to perceptions of relations within the realm of ideas; others have argued that sensitive knowledge is not strictly speaking a form of knowledge for Locke. (...) This chapter argues that Locke’s conception of sensitive knowledge is in fact compatible with his official definition of knowledge, and discusses his treatment of the problem of skepticism, both in the Essay and in the correspondence with Stillingfleet.

The Scottish philosopher David Hume is widely regarded as the greatest and most significant English-speaking philosopher and often seen as having had the most influence on the way philosophy is practiced today in the West. His reputation is based not only on the quality of his philosophical thought but also on the breadth and scope of his writings, which ranged over metaphysics, epistemology, morals, politics, religion, and aesthetics. The Handbook's 38 newly commissioned chapters are divided into six parts: Central Themes; (...) Metaphysics and Epistemology; Passion, Morality and Politics; Aesthetics, History, and Economics; Religion; Hume and the Enlightenment; and After Hume. The volume also features an introduction from editor Paul Russell and a chapter on Hume's biography. (shrink)

ABSTRACT: For the most part, this paper is not a philosophical paper in any strict sense. Rather, it focuses on the numerous exegetical puzzles in Sextus Empiricus’ two main passages on time (M X.l69-247 and PH III.l36-50), which, once sorted, help to explain how Sextus works and what the views are which he examines. Thus the paper provides an improved base from which to put more specifically philosophical questions to the text. The paper has two main sections, which can, by (...) and large, be read independently. Each is about a topic which, to my knowledge, has so far not been treated in detail. The first section is concemed with the argument structures of the two main passages on time in Sextus, pointing out various irregularities in the overall argument in both passages, as well as parallels and differences, and asks the question what kinds of scepticism and sceptical methods we find in the various parts of each passage. The second section focuses on the doxographical accounts of time in the two passages: what they are, how they compare with surviving parallels, to what philosophers we can attribute those accounts for which Sextus himself provides either no, or more than one, possible ascriptions, and how Sextus treats the doxographical material. This discussion is inspired by the contributions Michael Frede offered on this topic the day before his untimely death. (shrink)

Artikkelissa otan kantaa niin sanottuun voluntarismikiistaan Descartesin tahdon käsitykseen ja arvostelmateoriaan liittyen kannattaen epäsuoraa voluntarismia. Käsittelen erityisesti kysymystä voiko tahdolla Descartesin mukaan olla suora kontrolli ihmisen arvostelmasta pidättäytymiseen? Pitkään vallassa olleen tulkintasuuntauksen mukaan Descartesin käsityksessä tahdolla on kyky vaikuttaa doksastisiin tiloihin suoraan, pelkällä tahdon aktilla. Tätä kutsutaan suoraksi voluntarismiksi ja se tarkoittaa lyhyesti sanottuna sitä, että meillä on kyky hyväksyä, olla hyväksymättä sekä pidättäytyä arvostelemasta täysin tahdonvaraisesti. Tässä tekstissä kannatan kuitenkin epäsuoraa voluntarismia: tahto kykenee vaikuttamaan doksastiseen tilaan epäsuorasti vaikuttamalla uskomuksen (...) muodostamisen kannalta olennaisiin toimintoihin, erityisesti vahvoihin perusteisiin keskittymiseen. Argumentoin epäsuoran voluntarismin puolesta seuraavin tavoin: 1) Kohdat, joiden katsotaan puoltavan suoraa voluntarismia, voidaan yhtä lailla tulkita puoltamaan myös epäsuoraa voluntarismia, 2) Epäsuora voluntarismi on sekä filosofisesti että psykologisesti uskottavampi tulkinta siitä, kuinka ihminen arvostelmia muodostaa, ja 3) Epäsuora negatiivinen voluntarismi on koherentimpi ja ristiriidattomampi tulkinta epäilyn metodin käytöstä (siis yleisestä arvostelmasta pidättäytymisestä) Ensimmäisessä mietiskelyssä.

_ Source: _Volume 5, Issue 1, pp 29 - 54 This essay argues that the exploration of scepticism and its implications in the work of Stanley Cavell and David Hume bears more similarities than is commonly acknowledged, especially along the lines of what I wish to call “sceptical naturalism.” These lines of similarity are described through the way each philosopher relates the “natural” and “nature” to the universal, the necessary, and the conventional.

This essay deals with a selected part of an epistemological controversy provided by Tūsī in response to the skeptical arguments reported by Rāzī that is related to what might be called "intellectual skepticism," or skepticism regarding the judgments of the intellect, particularly in connection with self-evident principles. It will be shown that Rāzī has cited and exposed a position that seems to be no less than a medieval version of empiricism. Tūsī, in contrast, has presented us with a position that (...) rejects such empiricism. The comparative aim of this essay is to draw attention to some similarities as well as some points of divergence between the kind of skeptical debate we are focusing on here, and some relevant epistemological discussions in the later traditions in the West.

It is generally agreed that one of the key differences between ancient skepticism and modern and contemporary skepticism is that the ancient skeptic does not call into question the existence of the external world, but only our ability to know the properties or qualities of external objects. In this paper, I argue that in Sextus Empiricus's attack on the Epicurean criterion of truth one finds evidence that the ancient Pyrrhonist also suspends judgment about the existence of external objects.

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

Anthony Brueckner argues that Berkeleyan idealism lacks anti-sceptical force because of the way Berkeley draws the appearance/reality distinction. But Brueckner's case rests on a misunderstanding of Berkeley's view. Properly understood, Berkeleyan idealism does indeed have anti-sceptical force.

The essay is a comparative look at Descartes' and Pascal's epistemology. For so vast a topic, I shall confine myself to comparing three crucial epistemological topics, through which I hope to evince Descartes' and Pascal's differences and points of contact. Firstly, I will concentrate on the philosophers' engagement with skepticism, which, for each, had different functions and motivations. Secondly, the thinkers' relation to Reason shall be examined, since it is the fulcrum of their thought—and the main aspect that separates them. (...) Lastly, I will examine each philosopher's theist epistemology; this section, of course, will focus on how and by what means Descartes and Pascal set out to prove God's existence. The latter aspect shall take us back to each philosopher's relationship to Doubt: the title, " The Giants of Doubt ", in fact, implies a fundamental link between Descartes and Pascal through Doubt. In addition, and most importantly, the contrast between the two thinkers' epistemology inaugurates a decisive scission in modern thought of enormous repercussion: Descartes' sturdy rationalism initiated the great branch of modern scientific inquiry , while Pascal's appeal to the power of intuition and feelings would eventually be the precursor of the reaction to the enlightenment that invested Europe by the second half of the eighteenth century. This departure of thought, which in my view may be traced back to them, has not been the common conceit of the history of philosophy: the reaction to the enlightenment has customarily been regarded as stemming from its internal contradictions or at best from its more radical doctrines. The essay shall show that these strands of thought were both parallel and born out of the antithetical epistemologies of Descartes and Pascal. (shrink)

This paper analyzes the apraxia argument in Cicero’s Academica. It proposes that the argument assumes two modes: the evidential mode maintains that skepticism is false, while the pragmatic claims that it is disadvantageous. The paper then develops a tension between the two modes, and concludes by exploring some differences between ancient and contemporary skepticism.

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

Hegel's philosophy aims at responding to the questions raised by modern scepticism concerning the accessibility of the external world, of other minds, and of one's own mind. A key-role in Hegel's argumentative strategy against modern scepticism is played here by Hegel's theory of recognition. Recognition mediates the constitution of individual self-consciousness and intersubjectivity: self-knowledge is not logically independent of the awareness of other minds. At the same time, recognition institutes the possibility of objective reference to the world. In this way, (...) in Hegel the theory of recognition furnishes a unitary response to the threefold sceptical issue of the accessibility of the external world, of other minds, and of one's own mind. The reference to a common world of public objects is thus possible only thanks to the mediation of recognitive capacities that are naturally possessed and socially articulated, which make possible the triangulation between self, world and others.

Ancient philosophy knew two main skeptical traditions: the Pyrrhonian and the Academic. In this final paper of the three‐part series devoted to ancient skepticism, I present some of the topics about Academic skepticism which have recently been much debated in the specialist literature. I will be concerned with the outlooks of Arcesilaus, Carneades, and Philo of Larissa.

Several scholars familiar with Sextus Empiricus’s Pyrrhonism who have attentively read his Against the Ethicists have gotten the impression that something strange is going on in this book. For, at variance with the ‘official’ Pyrrhonian attitude of universal suspension of judgment, a number of passages of Against the Ethicists seem to ascribe to the Pyrrhonist both a type of negative dogmatism and a form of realism, which together amount to what may be called ‘moderate ethical realism’. The purpose of this (...) paper is to determine whether Sextus does embrace such a position in Against the Ethicists. (shrink)

Scholarship on ancient skepticism has undergone a remarkable renaissance in the last three decades. Specialists in ancient philosophy have explored the complex history of the Greco‐Roman skeptical traditions and discussed difficult philological and exegetical issues. But they have also assessed the philosophical significance of the various ancient skeptical outlooks. In this first paper, I provide a general presentation of this area of study, while in the two subsequent articles I will focus on some of the topics that have been the (...) object of much attention in the recent literature on ancient skepticism.

Pyrrhonism was one of the two main ancient skeptical traditions. In this second paper of the three‐part series devoted to ancient skepticism, I present and discuss some of the issues on Pyrrhonian skepticism which have been the focus of much attention in the recent literature.

Few address the extent to which William James regards the neo-Lamarckian account of “direct adaptation” as a biological extension of British empiricism. Consequently few recognize the instrumental role that the Darwinian idea of “indirect adaptation” plays in his lifelong efforts to undermine the empiricist view that sense experience molds the mind. This article examines how James uses Darwinian thinking, first, to argue that mental content can arise independently of sense experience; and, second, to show that empiricists advance a hopelessly skeptical (...) position when they insist that beliefs are legitimate only insofar as they directly correspond to the observable world. Using his attacks on materialism and his defense of spiritualism as examples, I particularly consider how Darwinian thinking enables him to keep his empiricist commitments while simultaneously developing a pragmatic alternative to empiricistic skepticism. I conclude by comparing his theory of beliefs to the remarkably similar theory of “memes” that Richard Dawkins uses to attack spiritualistic belief—an attack that James anticipates and counters with his pragmatic alternative.

The history of the transmission, recovery and posthumous influence of ancient scepticism is a fascinating chapter in the history of ideas. An extraordinary collection of philosophical texts and some of the most challenging arguments ever devised were first lost, then only partly recovered philologically, and finally rediscovered conceptually, leaving Cicero and Sextus Empiricus as the main champions of Academic and Pyrrhonian scepticism respectively. This chapter outlines what we know about this shipwreck and what was later salvaged from it.
