In the Synopsis to the Meditations Descartes assures us that ‘extensive doubt… [provides] the easiest route by which the mind may be led away from the senses’. And in the Fifth Replies Descartes adds that it is essential to a proper understanding of the Meditations that ‘the entire testimony of the senses should be regarded as uncertain and even as false’. But to deny our ordinary trust in the senses on the grounds of such ‘hyperbolic’ or ‘metaphysical’ doubts as that (...) one might be dreaming or the victim of an evil demon is, as Descartes himself puts it, quite mad: ‘no sane person has ever seriously doubted that there really is a world and that human beings have bodies’. We seem, then, to be confronted with a dilemma: on the one hand, the skepticism about the senses that we find in the First Meditation must be taken seriously. On the other hand, it is, in some sense, a sham. How, then, are we to understand these doubts? (shrink)

Dans la première partie de son article « Une morale est-elle compatible avec le scepticisme? », Jules Vuillemin propose une interprétation du scepticisme de Pyrrhon d’Élis et s’interroge sur sa compatibilité avec une vie morale. La présente contribution s’attache à resituer la lecture de Vuillemin dans l’histoire du pyrrhonisme ainsi que dans les débats récents à son sujet, et à la discuter en la comparant au néo-pyrrhonisme de Sextus Empiricus. À suivre Vuillemin, Pyrrhon suspend son jugement par rapport à tout, (...) y compris ses impressions. Cette suspension universelle provoquerait une impassibilité totale et fournirait une ligne de conduite, mais serait assez difficile à adopter. Nous suggérons que suspendre son jugement sur ses propres impressions n’est pas difficile, mais impossible ; que la façon dont, selon Vuillemin, cette suspension fournirait au sceptique une ligne de conduite implique une contradiction ; et qu’il existe une autre façon d’expliquer comment le sceptique peut, dans certaines limites, maintenir une ligne de conduite.

En este trabajo intento mostrar que la función de la doctrina heraclítea en el Teeteto es argumentar a favor de la equivalencia entre la tesis de Protágoras y la definición de Teeteto “la percepción es conocimiento”, y que de esta manera la doctrina apoya la relatividad del conocimiento. Esta lectura va en contra de quienes sostienen que Platón introduce la doctrina porque la cree correcta acerca de lo sensible, y va un paso más allá de la interpretación que afirma que (...) Platón introduce la doctrina como una tesis ontológica para apoyar la tesis de Protágoras. (shrink)

The Renaissance sceptic and medical doctor Francisco Sanchez has been rather unduly neglected in scholarly work on Renaissance scepticism. In this paper I discuss his scepticism against the background of the ancient distinction between Academic and Pyrrhonian scepticism. I argue that Sanchez was a Pyrrhonist rather than, as has been claimed in recent years, a mitigated Academic sceptic. In keeping with this I shall also try to show that Sanchez was crucially influenced by the ancient medical school of empiricism, a (...) school closely allied with Pyrrhonism. (shrink)

In Fear of Knowledge, Paul Boghossian presents a series of arguments against epistemic relativism and constructivism, doctrines that he considers to have exerted an overly unjustified influence over the human and social sciences in the past two decades. In the presentation of his arguments, Boghossian charts out a terrain that closely identifies relativism with skepticism. Yet, the relationship between the two does not seem to be a simple matter of entailment or implication. The purpose of this paper is to clarify (...) the landscape surrounding relativism and skepticism and thereby to highlight their difference. The implications of such a clarification will include illustrating that some arguments thought to be against relativism are actually against skepticism, that there are very different ways of understanding the relationship between relativism and skepticism, and that a commitment to either relativism or skepticism does not entail commitment to the other. The overall objective is to show that Boghossian's conception of the terrain is incorrect and to offer an explanation for this pervasive misconception about the connection between relativism and skepticism.

Kant presents three principles of modality in the Critique of Pure Reason. Historically, commentators have mostly disregarded them; a few have rejected them outright. In recent years, however, a consensus has begun to develop around the idea that the role of these principles is to rule out certain metaphysical doctrines. I argue that this understates their importance. Rather, the principles of modality are essential conditions of the possibility of experience. I conclude by examining the question of their truth, which, I (...) argue, can only be grasped by considering them as postulates—i.e., as practical propositions of a certain kind. (shrink)

This paper will offer a systematic reconstruction of al-Ġazālī’s Sceptical Argument in his celebrated Deliverer/Delivered from Going Astray (al-Munqiḏ/al-Munqaḏ min al-Ḍalāl). Based on textual evidence, I will argue that the concept of certainty (yaqīn) in play in this argument is that of the philosophers—most notably Ibn Sīnā—and that it is firmly tied to demonstration (burhān) and hence to the materials of syllogism (mawwād al-qiyās). This will show that contrary to what many scholars believe, this Sceptical Argument is al-Ġazālī’s discovery of (...) a latent sceptical problem in Muslim philosophers’ epistemological theories based on Aristotle’s Posterior Analytics that escaped even the agile mind of aš-šayḫ ar-raʾīs Ibn Sīnā. This reconstruction will also shed some light on the widespread assumption that al-Ġazālī anticipates Descartes’s sceptical considerations in the First Meditation. I will argue that not only do the two thinkers use incompatible strategies to reach their respective sceptical conclusions, but both their conclusions and their use of God in refuting them are also essentially non-identical. The conclusion is that the two sceptical arguments are essentially different. (shrink)

La propuesta inmaterialista de Berkeley, elaborada definitivamente en sus Principles (1710), tiene como antecedente remoto los postulados del capadocio Gregorio de Nisa, quien en algunas de sus obras desarrolló argumentos, en relación con la materia, muy semejantes a los que planteó Berkeley casi catorce siglos después. El presente escrito tiene por objetivo mostrar que las concepciones de ambos pensadores tienen elementos en común, lo que permite sostener que el filósofo de Cesarea es un antecede lejano del inmaterialismo berkeleyano. // Berkeley's (...) immaterialism has as a remote antecedent in the postulates of the Cappadocian Gregory of Nyssa, who in some of his works developed arguments, concerning the matter, very similar to those that Berkeley presented almost fourteen centuries later. This paper aims to show that both philosophical conceptions have elements in common, which allows us to assert that the Cappadocian father is a distant precedent of Berkeley's immaterialism.

This paper is a test case for the claim, made famous by Myles Burnyeat, that the ancient Greeks did not recognize subjective truth or knowledge. After a brief discussion of the issue in Sextus Empiricus, I then turn to Plato's discussion of Protagorean views in the Theaetetus. In at least two passages, it seems that Plato attributes to Protagoras the view that our subjective experiences constitute truth and knowledge, without reference to any outside world of objects. I argue that these (...) passages have been misunderstood and that on the correct reading, they do not say anything about subjective knowledge. I then try out what I take to be the correct reading of the passages. The paper concludes with a brief discussion of the importance of causes in Greek epistemology. (shrink)

Following the lead of Duncan Pritchard’s “Wittgensteinian Pyrrhonism,” this paper takes a further, comparative and contrastive look at the problem of justification in Sextus Empiricus and in Wittgenstein’sOn Certainty. I argue both that Pritchard’s stimulating account is problematic in certain important respects and that his insights contain much interpretive potential still to be pursued. Diverging from Pritchard, I argue that it is a significant and self-conscious aspect of Sextus’ sceptical strategies to call into question large segments of our belief systemen (...) masseby exposing as apparently unjustifiable fundamental propositions which are closely related in their linchpin role to Wittgenstein’s hinge propositions. In the first instance, the result is a more complex account of both a deeper affinity between Wittgenstein’s approach to hinge propositions and Sextus’ approach to what I termarchaipropositions and a divergence between the two. In the second instance, I suggest how the comparison withOn Certaintycan be illuminating for the interpreter of Sextus. In particular, it can help us to see how the Pyrrhonist’s everyday conduct—common assumptions to the contrary notwithstanding—involves rational procedures of justification, in line with a naturalism reminiscent of Wittgenstein. Furthermore, it can help us to reflect on the Pyrrhonist’s attitude to what Wittgenstein would have called her ‘worldview’. Throughout, I suggest that the comparison with Wittgenstein is interesting, although it must be cashed out differently, not only on the interpretation—or, perhaps, strand—of ancient Pyrrhonism which has the sceptic exempt ordinary beliefs from her suspension of judgement, but also on the interpretation which has her disavow all beliefs categorically.

Sextus responds to the Dogmatists’ criticism that the Sceptics cannot investigate Dogmatic theses, formulating his own version of Meno’s puzzle against them. He thus forces them to adopt υοεῐυ ἁπλῶς – a way of thinking that does not carry any commitment to the reality of what someone thinks – as their only solution to the puzzle and as the necessary starting point of their investigation. Nοεῐυ ἁπλῶς avoids Dogmatic assumptions without making use of the Sceptical argumentation that leads to suspension (...) of judgment. It constitutes a novel answer to Meno’s puzzle, Dogmatism- and Scepticism-free, with important consequences both for Dogmatism and for Scepticism. (shrink)

In this paper, I examine several key issues relating to the definition of knowledge as perception in the first part of Plato's Theaetetus. I begin by explaining the workings of the ‘secret doctrine’ of perception, which is introduced in order to support the idea that perception is incorrigible, and then turn to examine the two refutations of the definition of knowledge as perception which appear at the end of the first part of the Theaetetus. I shall present and explain distinct (...) lines of interpretation pertaining to these passages and explore the consequences they attempt to draw regarding Plato's views on the perceptual world, the nature of perception and how these bear on his conception of knowledge.

ABSTRACT In his 1981–82 lectures The Hermeneutics of the Subject, Michel Foucault claims that a significant portion of the modern historiography of ancient philosophy tends to discredit the ethical framework of epimeleia heautou (“care of the self”). The thematic analysis of knowledge in the historiography of ancient philosophy overshadows the theme of care of the self. Taking Foucault’s claim as a point of departure, the aim of this paper is twofold. First, the paper provides a genealogy of the early Hellenistic (...) Academy, from Polemo to Arcesilaus. Second, the paper demonstrates that for Arcesilaus, the alleged pioneer of what modern historiography has designated the Academy’s epistemological scepticism, philosophy is not restricted to a continual search for knowledge at a theoretically rarefied level of challenging arguments or discursive statements. This paper situates Arcesilaus’ opposition to early Stoic epistemology within the framework of Academic epimeleia heautou, and defends the thesis that under Arcesilaus the Hellenistic Academy undergoes a shift in the practice of care of the self.

Are all forms of difference contained in what is, or is there some form of difference that escapes, negates, or constitutes what is? Parmenides and Heraclitus may have had the greatest effect on how philosophy has answered this question. This paper shows that Heraclitus is not a partisan of difference: identity and difference are mutually generative and equally fundamental. For his part, Parmenides both makes an argument against opposing being and non-being in the False Road Story, and then uses precisely (...) this opposition to put up signs on the Way of Truth. The paper responds to this impasse by making the case that the poem’s philosophical character is didactic, rhetorical, and mythological, which is why both these signs, and the opposition between non-being and being, are presented as names created by mortals.

Inattention to the historical antecedents of current philosophical views may impoverish our arguments in defense of those views. A case in point, examined here, concerns the difference that can be made for current strategies designed to defend religious belief by carefully reconsidering the position of historical sceptics.

There is a long history of philosophers granting a privileged epistemic status to cognition of directly present objects. In this paper, I examine three important historic accounts which provide different models of this cognitive state and its connection with its objects: that of the Stoics, who are corporealists and think that ordinary perception may have an epistemically privileged status, but who seem to struggle to accommodate non-perceptual cognizance; that of Augustine, who thinks that incorporeal objects are directly present to us (...) in ‘intellectual perception’, and that, by way of contrast, ordinary sense-perception does not have a privileged epistemic status; and that of William of Ockham, who allows for unmediated action at a distance and is fairly generous about what counts as being directly present.

_ Source: _Volume 7, Issue 3, pp 147 - 172 The Indian Buddhist philosopher Vasubandhu has seldom been considered in conjunction with the problem of external-world skepticism despite the fact that his text, _Twenty Verses_, presents arguments from ignorance based on dreams. In this article, an epistemological phenomenalist interpretation of Vasubandhu is supported in opposition to a metaphysical idealist interpretation. On either interpretation, Vasubandhu gives an invitation to the problem of external-world skepticism, although his final conclusion is closer to skepticism (...) on the epistemological phenomenalist interpretation. The article ends with reflections on what light Vasubandhu might shed on the issue of whether skepticism is a natural problem in epistemology as well as why, despite Vasubandhu, the skeptical problem was not a central issue in the later Indian tradition.

The standard interpretation of "Theaetetus" 152-160 has Plato attribute to Protagoras a relativistic theory of truth and existence. It is argued here that in fact the individuals of Protagorean worlds are inter-Personal. (thus the Protagorean theory has public objects, but private truth). Also, a new interpretation is offered of Plato's use of heraclitean flux to model relativism. The philosophical and semantic consequences of the interpretation are explored.

Donald Davidson has argued that 'most of our beliefs must be true' and that global scepticism is therefore false. Davidson's arguments to this conclusion often seem to depend on externalist considerations. Davidson's position has been criticised, however, on the grounds that he does not defeat the sceptic, but rather already assumes the falsity of scepticism through his appeal to externalism. Indeed, it has been claimed that far from defeating the sceptic Davidson introduces an even more extreme version of scepticism according (...) to which we cannot even know the contents of our own minds. This paper argues that these criticisms are mistaken and that Davidson does indeed have grounds to argue that scepticism is false. The externalism that figures in Davidson's antisceptical arguments is shown to be merely an element in Davidson's overall holism according to which the very possibility of having beliefs that could be true or false depends on most of those beliefs being true and their contents known.

In the present paper I shall argue that the real problem here is the very idea that there is a dilemma that compels us to choose sides. We can hold both that the meditator's doubts are fully serious, and that they leave the perspective of common sense largely unscathed. The key to dissolving the dilemma is to see that the meditator observes a distinction between two levels of epistemic standards: the very demanding standards appropriate to certainty, understood in a rather (...) technical sense of that term; and the commonplace standards appropriate to reasonable belief. The significance of this levels distinction has not been widely appreciated but it has important consequences both for how we are to understand the skepticism about the senses that is at issue and for appreciating the extent to which Descartes acknowledges and retains our natural trust in the senses. I aim to show that the meditator’s skepticIsm about the senses specifically concerns the possibility of sensory certainties, and is quite serious. It is intended to lead one to a stable change of mind about what is most certain. But a skepticIsm about sense-based certainty leaves the matter of whether experience provides a reliable basis for belief untouched by reasonable doubt. Since the meditator's doubts presuppose very demanding standards they have no bearing on our assessments from within the common sense perspective. I defend this view by arguing that the methodological 'withdrawal of assent' from perceptual beliefs is a mere pretense that is compatible with continued endorsement. Despite the seriousness with which the method of doubt is pursued, there is an important sense in which the meditator never doubts the basic deliverances of his senses. This helps explain the practical insulation of perceptual beliefs from skepticism. With one minor qualification, the meditator retains his natural trust in the senses throughout - although Descartes’ rhetoric sometimes suggests otherwise. Note that I shall be exploring the skepticism about the senses as we find it in the First Meditation. This paper does not purport to discuss all of the skeptical doubts of the First Meditation, e.g., skepticism about mathematical truths, God's existence and reason. Instead I shall focus solely upon the ways in which the meditator's doubts bear on his perceptual beliefs. The rationale for this restriction is twofold: 1) in the first place Descartes describes the general aim of the skeptical doubts of the First Meditation m terms of 'freeing us from our preconceived opinions, and providing the easiest route by which the mind may be led away from the senses’. I am specifically concerned to qualify this ambition and argue that Descartes retains throughout his preconceived trust in the reliability of the senses; and 2) the Meditations has long been thought to provide the grounds for a radical form of external world skepticism which not only denies us knowledge of, but also any reason to believe in, the existence of an external world. My discussion of Descartes' perceptual doubts is intended to show just how distant any such skepticism is from Descartes' own thoughts and intentions. (shrink)

The purpose of the present paper is twofold. First, to examine what beliefs, if any, underlie (a) the Pyrrhonist’s desire for ataraxia and his account of how this state may be attained, and (b) his philanthropic therapy, which seeks to induce, by argument, ejpochv and ataraxia in the Dogmatists. Second, to determine whether the Pyrrhonist’s philanthropy and his search for and attainment of ataraxia are, as scholars have generally believed, essential aspects of his stance.

Julia Annas has affirmed that the kind of modern moral skepticism which denies the existence of objective moral values rests upon a contrast between morality and some other system of beliefs about the world which is not called into doubt. Richard Bett, on the other hand, has argued that the existence of such a contrast is not a necessary condition for espousing that kind of moral skepticism. My purpose in this paper is to show that Bett fails to make a (...) good case against Annas’ thesis. To accomplish this, it will be helpful to consider the Pyrrhonean attitude towards morality as expounded in Sextus Empiricus’ work. (shrink)

Modern science is not linguistically original in hypothesizing the existence of dark matter. For Plotinus, the matter that underlies all perceptible objects, is essentially obscure and describable only in the negative terms of what it lacks by way of inherent properties. In formulating this theory of absolute matter, Plotinus took himself to be interpreting both Plato and Aristotle, with the result that his own position emerges as a highly original and equivocal synthesis of this tradition. Plotinus did not claim that (...) matter is nothing, but the puzzling status he attributes to it can be aptly compared to Berkeley's doctrine that material substance is a self-contradictory notion.

In some of Plato’s early dialogues we find a concern with correctly ascertaining the contents of a particular kind of one’s own psychological states, cognitive states. Indeed, one of the achievements of the elenctic method is to facilitate cognitive self-knowledge. In the Alcibiades, moreover, Plato interprets the Delphic injunction, ‘know yourself’, as crucially requiring cognitive self-knowledge, and ending in knowing oneself as subject to particular epistemic norms. Epistemic authority for self-knowledge is, for Plato, conferred on the basis of correct application (...) of norms to cognitive self-ascriptions, and not confined to the first-personal perspective. This implies first-personal plural epistemic authority for self-knowledge. (shrink)

This paper considers Berkeley’s use of Plato in Siris. Berkeley’s engagement with ancient thinkers in Siris has been a source of puzzlement for many readers. In this paper I focus on Siris § 266. In particular, I consider why Berkeley says of the Platonists that they “distinguished the primary qualities in bodies from the secondary” and why, given his own well-known misgivings about the distinction, he characterizes this as part of a “notion of the true system of the world.” I (...) argue that in Siris Berkeley accepts a distinctive form of corpuscularianism, and that he thinks a distinction between primary and secondary qualities follows from this. I further argue that in § 266, and elsewhere in Siris, Berkeley engages in a careful reading of Plato’s Timaeus, which he uses to bolster his defense of the compatibility between corpuscularianism and his immaterialist idealism.

This paper demonstrates that two signature methodological concepts in Husserl’s transcendental phenomenology, the epoché and the phenomenological reduction, derive from his reflections on the history and significance of epistemological skepticism in the Western tradition. Drawing on his Lectures on Logic and Epistemology (Hua XXIV) from the Winter semester of 1906–07, it is argued that Husserl derives his conception of the fundamental task of transcendental philosophy from his reading of a novel skeptical challenge posed by David Hume’s philosophy—a kind of skeptical (...) challenge that Husserl did not recognize in his earlier treatments of Hume. On Husserl’s revised reading, Hume promotes a certain kind of philosophical “despair” (Verzweiflung) or, as it may be called today, “quietism” as the only possible response to the traditional problems of epistemology stemming back to the ancient skeptics. Husserl’s criticism of Hume’s quietism is presented. And Husserl’s reading of Descartes’s cogito as the first decisive uncovering of the limits of epistemological skepticism in the Western tradition is shown to be the source of two key elements of Husserl’s positive alternative to Humean epistemological quietism, which ultimately become the heart of a novel conception of critical transcendental philosophy. These two key elements are the phenomenological epoché and phenomenological reduction. Husserl’s arguments are presented for the claim that these are essential parts of any epistemological program that can answer traditional skeptical challenges. (shrink)

McDowell and Merleau-Ponty share a critical attitude towards a certain Cartesian picture of the mind. According to the picture in question nothing which properly belongs to subjectivity can be hidden to the subject herself. Nevertheless there is a striking asymmetry in how the two philosophers portray the problematic consequences of such a picture. They can seem to offer exact opposite views of these consequences, which, given the almost identical characterization of the transparency claim, is puzzling. I argue that a closer (...) look at the prima facie puzzling asymmetry dissolves the apparent disagreement and reveals a deeper agreement concerning both the nature and the origin of the problems haunting the Cartesian picture in question. Both McDowell and Merleau-Ponty argue that on the picture of the relation of between mind and world in question, we lose our grip on the very idea of a perceptual appearance. Furthermore, the two authors regard a certain conception of nature as conceived in the image of science, as one of the crucial elements in making the picture of the mind in question look attractive.

I describe and discuss one particular dimension of disagreement in the philosophical literature on episodic memory. One way of putting the disagreement is in terms of the question as to whether or not there is a difference in kind between remembering seeing x and remembering what x looks like. I argue against accounts of episodic memory that either deny that there is a clear difference between these two forms of remembering, or downplay the difference by in effect suggesting that the (...) former contains an additional ingredient not present in the latter, but otherwise treating them as the same thing. I also show that a recent ‘minimalist’ approach to episodic memory (Clayton & Russell in Neuropsychologia 47 (11): 2,330–2,340, 2009; Russell & Hanna in Mind & Language 27 (1): 29–54, 2012) fails to give a satisfactory explanatory account of the difference between the two types of remembering. I finish by sketching an alternative approach to episodic memory, which turns on the idea that episodic recollection recruits a specific form of causal reasoning that provides for a concrete sense in which remembered events are remembered as belonging to the past.

While the Academic sceptics followed the plausible as a criterion of truth and guided their practice by a doxastic norm, so thinking that agential performances are actions for which the agent assumes responsibility, the Pyrrhonists did not accept rational belief-management, dispensing with judgment in empirical matters. In this sense, the Pyrrhonian Sceptic described himself as not acting in any robust sense of the notion, or as ‘acting’ out of sub-personal and social mechanisms. The important point is that the Pyrrhonian advocacy (...) of a minimal conception of ‘belief’ was motivated by ethical concerns: avoiding any sort of commitment, he attempted to preserve his peace of mind. In this article, I argue for a Cartesian model of rational guidance that, in line with some current versions of an agential virtue epistemology, does involve judgment and risk, and thus which is true both to our rational constitution and to our finite and fallible nature. Insofar as epistemic humility is a virtue of rational agents that recognise the limits of their judgments, Pyrrhonian scepticism, and a fortiori any variety of naturalism, is unable to accommodate this virtue. This means that, in contrast to the Cartesian model, the Pyrrhonist does not provide a satisfactory answer to the problem of cognitive disintegration. The Pyrrhonist thus becomes a social rebel, one that violates the norm of serious personal assent that enables the flourishing of a collaborative and social species which depends on agents that, however fallible, are accountable for their actions and judgments.

A well-established tradition has argued that it is not legitimate to attribute to Parmenides a Fregean semantics, i.e. the distinction between ‘naming’ and ‘meaning’. Nonetheless, Parmenides claims more than once (B 8.53, B 9.1) that mortalsdo namereality, although incorrectly. As many scholars have emphasised, because it is fair neither to conclude that mortals’ names are ‘empty names’ nor dismiss Opinion's account (i.e., broadly speaking, the mortals’ account of reality) itself as meaningless, it seems that Parmenides is suggesting that some kind (...) of distinction between what names refer to and what names mean must be drawn. In view of this, what is Parmenides’ account of names?My suggestion is that in order to explain the Eleatic philosophy of language (and the Eleatic account of names) a step back is required. More specifically, Parmenides’ epistemology has to be taken into account. Indeed, if we assume that Parmenides is arguing for an ‘epistemological disjunctivism’ – such that the veridical and truthful state and the erroneous and deceptive state are essentially different – it will be clear that he is further arguing for what could be defined as a ‘semantic disjunctivism’, so that true speech and false speech are essentially different as well.

Recent research in Baroque Scholastic and early modern meditational exercises has demonstrated similarity between Descartes’s Meditations and St. Teresa of Ávila’s El Castillo Interior. While there is growing agreement on the influence of Catholic meditations on Descartes, the extent of Teresa’s role is debated. Instead of discussing the full extent of Teresa’s influence, this paper concentrates on one example of the considered influence: the skeptical scenario of demonic deception, having clear anticipation in Teresa’s work where the exercitant faces off against (...) deceiving demonic forces, which confound and temporarily halt the meditative progress. The paper analyzes Teresa’s use of deceptive demons and its influence on the Cartesian Evil Demon scenario, while contrasting both with a discussion of demonic deception in the late Medieval and Baroque Scholastic context, arguing that demonological discussions in 1500s allowed both Teresa’s and Descartes’s deceivers to not only cause diversions but to make the deception laborious to resist.

This dissertation examines the relationship of skepticism and philosophy in the work of G.W.F. Hegel. Whereas other commentators have come to recognize the epistemological significance of Hegel's encounter with skepticism, emphasizing the strength of his system against skeptical challenges to the possibility of knowledge, I argue that Hegel develops his metaphysics in part through his ongoing engagement with the skeptical tradition. As such, I argue that Hegel's interest is not in refuting skepticism, but in defining its legitimate role within the (...) project of philosophical science. Hegel finds that historical forms of skepticism have misunderstood their own activity and thus have drawn the wrong conclusions from the epistemological challenges that they raise. For Hegel, these challenges lead not to the suspension of judgment, as many skeptics have assumed, but to an insight into the fundamental nature of reality itself. For this reason, I argue that it is important to distinguish between historical forms of skepticism (e.g., Pyrrhonism) and the "self-completing skepticism" that Hegel describes in the Phenomenology of Spirit. It is the latter sense of skepticism, I argue, that one finds at work in Hegel's own philosophical project at nearly every stage of his career. (shrink)
