Commentators have noticed the striking similarities between the skep­tical arguments of al-Ghazālī’s Deliverance from Error and Descartes’ Discourse on Method and Meditations on First Philosophy. However, commentators agree that their solutions to skepticism are radically different. Al-Ghazālī does not use rational proofs to defeat skepticism; rather, he relies on a supernatural light [nūr] sent by God to rescue him from skepticism. Descartes, on the other hand, relies on the natural light of reason [lumen naturale] to (...) prove the existence of God, mind, and body. In this paper, I argue that Descartes’ solution is closer to al-Ghazālī’s than commentators have allowed. A close reading of the cosmological argument of the Third Meditation reveals that there is also a type of divine intervention em­ployed in the Meditations, which helps Descartes defeat skepticism. This reading may buttress the case made by some that al-Ghazālī influenced Descartes; but more importantly, it requires us to rethink key features of Descartes’ epistemology. (shrink)

This dissertation explores the relationship between an extensive skepticism concerning the existence of the world and the concept of mental representation in Sextus Empiricus and Descartes. In Chapter 1, it is argued, against the traditional interpretation, that Sextus does espouse such an extensive skepticism; that, at the same time, he is using a very strong causal concept of experience according to which the object of the experience is 'the cause' of the experience; and that he can consistently (...) embrace these two positions because his skepticism is flexible enough that he can always turn around and undermine the very presuppositions implicit in the use of a concept, which he has previously used to prove a skeptical point. Chapter 1 also includes an examination of Descartes's skepticism in the First Mediation, and it is argued that this skepticism undermines not only the Scholastico-Aristotelian causal view of mental representation, but also the weaker principle to the effect that we cannot have representations of simple things that compose those complex representations are caused by similar simple things. But Descartes's skepticism in the First Meditation is not as flexible as Sextus's. Hence, he cannot overturn his skeptical arguments by using any strong causal principle of mental representations. Chapters 2 and 3 together include an extensive defense of the view that the causal principle that Descartes uses in the Meditations to prove the existence of God and of physical objects is so weak as to allow that all our ideas--except the idea of God--are generated by our minds, and that this is the only principle he uses and needs in the Meditations and elsewhere. To this end, Chapter 2 examines the concepts of objective reality, material falsity, etc. It includes a defense of an interpretation of Descartes's view of ideas, according to which ideas have two levels of content: a seemingly representational and a truly representational. I relate this interpretation to his views on objective reality, material falsity, sensible qualities, the causes of innate ideas, and the nature of sensory perception and imagination. (shrink)

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

Commentaries on Hume's Treatise 1.4.1, "Of scepticism with regard to reason," have focused on the argument that an initial lack of certainty concerning the conclusion of an inference gradually diminishes to zero. In my view, Hume offers this famous argument only after, and as corollary to, a far more interesting skeptical argument concerning demonstrative reasoning, which occurs at the very beginning of Treatise 1.4.1. I focus on this neglected argument, point to its Cartesian roots, and draw a distinction between ordinary (...) doubts and a radical skeptical doubt about the inevitable interference of fallible faculties in our demonstrative inferences. Hume suggests that, in common life and science, solutions to ordinary doubts concerning human fallibility themselves rely on causal reasoning-that we have applied inferential rules correctly in any given instance is a "matters of fact" conclusion, thus it is supported by the only kind of evidence that such a conclusion can have. Hume's argument brilliantly reverses the force of the increased confidence normally acquired on the basis of such causal reasoning. Once we have realized, in the radically skeptical frame of mind, that in our attempts to improve and evaluate demonstrative reasoning we use merely causal reasoning, there is no longer the hope of a progressive adjustment of the exercise of our faculties to an assumed objective validity of our demonstrative rules. The increase in assurance by causal methods only amounts to "the addition of new probabilities," and there is no gradual transition from probability to demonstratively certain knowledge. Hume thereby reaches a radical skeptical doubt regarding the possibility of our ever attaining genuinely certain demonstrative knowledge - and, unlike Descartes, he reaches this doubt without the external device of an all-powerful deceiver. Los comentarios sobre la sección "Of scepticism with regard to reason" en A Treatise on Human Nature de David Hume se han concentrado en el argumento según el cual, la falta inicial de convicción certera acerca de la conclusión de una inferencia cualquiera disminuye gradualmente a cero. Sostengo que Hume ofrece este famoso argumento solamente después y como corolario de un argumento escéptico mucho más interesante acerca del razonamiento deductivo, el cual aparece al principio de esta sección. Me concentro en este primer argumento, señalo sus raíces cartesianas, y establezco una distinción entre dudas comunes y una duda escéptica radical acerca de la interferencia inevitable, en nuestros razonamientos deductivos, de facultades mentales falibles. Hume sugiere que, en la vida cotidiana y en la ciencia, las soluciones a las dudas acerca de la falibilidad humana, en sí mismas se apoyan en razonamientos de carácter causal: si hemos aplicado correctamente una regla inferencial o no, en una instancia específica, es en sí misma una conclusión acerca de lo que Hume llama "matters of fact". Por lo tanto, está basada en el único tipo de evidencia que tal conclusión puede poseer. El argumento brillante de Hume invierte negativamente la confianza creciente que normalmente adquirimos sobre la base de tal razonamiento causal. Una vez que tomamos en cuenta, desde el punto de vista escéptico radical, que en nuestros intentos de mejorar y evaluar razonamientos deductivos usamos meramente razonamientos causales, se cierra la posibilidad de ajustar progresivamente el ejercicio de nuestras facultades mentales a una supuesta validez objetiva de las reglas de deducción. El aumento de la confianza en nuestras inferencias está basado en métodos causales, por lo tanto resulta en "la adición de nuevas probabilidades", y no existe una transición gradual desde la probabilidad más alta hasta el conocimiento certero demostrativo. De esta manera, Hume llega a una duda escéptica radical acerca de la posibilidad de lograr conocimiento demostrativo genuinamente certero. A diferencia de Descartes, Hume obtiene esta duda radical sin apelar a un elemento externo a nuestras facultades mentales, tal como el todopoderoso que engaña en la Primera Meditación de Descartes.

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 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)

Abū Hāmid al-Ghazālī (1058–1111 c.e .) is well known, among other things, for his account, in al-Munqidh min al-ḍalāl (Deliverance from error), of a struggle with philosophical skepticism that bears a striking resemblance to that described by Descartes in the Meditations . This essay aims to give a close comparative analysis of these respective accounts, and will concentrate solely on the processes of invoking or entertaining doubt that al-Ghazālī and Descartes describe, respectively. In the process some subtle (...) differences between them in this regard will be brought to light that are relevant to the comparative issue of the respective solutions at which they arrive. The latter issue will not be touched upon here, although the present discussion is intended as a prelude to a future treatment of that topic. (shrink)

Based on the distinction drawn by James Conant between Cartesian skepticism and Kantian skepticism, I intend to show that Wittgenstein’s remarks on dreaming should not be understood as a direct attack on the former, as commonly held, but as an indirect attack on it, for Wittgenstein approaches Descartes’ dreaming hypothesis by changing the very problematic at stake. Wittgenstein’s attack on skepticism takes one step back from a question about how to distinguish between dreaming that one is (...) experiencing something and actually experiencing it, for this attack focuses on the linguistic conditions of the possibility of something that the Cartesian problematic takes for granted, that is, the very possibility of saying “I am dreaming.” I also intend to show that Wittgenstein’s remarks on dreaming should be read in light of his claim that skepticism is nonsensical put forward in the Tractatus logico-philosophicus as well in his last writings. More specifically, I intend to show that the words “I am dreaming” are nonsensical in the same sense as the alleged proposition “There are physical objects” and the expression of doubt about the existence of physical objects or the external world.

“A belief is knowledge only when proof against all doubt, even the most hyperbolic” – so premises Descartes. If unable to rule out the possibility that one is deceived by a demon (or is embodied in an envatted brain), therefore, one knows neither what one ostensibly sees, nor the truth of any conclusion one may infer from such “data,” or at least it cannot be any such inference that gives one knowledge of the truth of its conclusion.

What do Philosophers do? Skepticism and the Practice of Philosophy. By Maddy Penelope.

Although Descartes presents himself as an adversary of skepticism, in contemporary epistemology he is celebrated much more for his presentation of the skeptical problem than for his efforts to solve it. The ‘Cartesian skepticism’ of the evil genius argument remains a Standard starting point for current discussions, a starting point that is seen to provide such a powerful challenge to knowledge that while one as much as contemplates such arguments one loses the right to ascribe knowledge to (...) anyone. Even Descartes's less radical skeptical arguments are still widely credited as having tremendous force: Barry Stroud, for example, argues at length that no satisfactory response has yet been given to the dream argument of the First Meditation. The Cartesian response to skepticism, on the other hand, is not nearly so warmly received. In the current literature on skepticism one does not find much resistance to Stroud's assessment of the Cartesian response to skepticism as utterly unpromising, nor to his diagnosis of its central fault: the Cartesian response depends on a series of theological claims that Descartes does not show to be plausible, let alone true.

In this paper, I present an interpretation of Descartes that deemphasizes his skepticism. I analyze a selection of remarks from Descartes’ correspondence in which he makes judgments about the skeptics. I argue that such remarks display Descartes’ attitude of contempt for skeptical philosophy. Since Descartes associates the skeptics with the activity of constant and total doubting and yet presents scenarios that seemingly arise from extreme doubt—like the malicious demon hypothesis—I look at what Descartes says (...) in the correspondence about his own use of doubt in his published works. Descartes distances himself from the skeptics because he claims that whereas they doubt everything and, in so doing, act heretically, he uses doubt for a noble purpose. I suggest that although Descartes is influenced by skeptical ideas and considers skeptical argumentation to be useful, his strategic use of such argumentation should not lead us to believe that he condones skepticism. Quite the contrary, most of his remarks on the subject show that Descartes is highly critical or dismissive of skeptical ideas. Therefore, I argue that it is more accurate to characterize Descartes as a philosopher generally opposed to skepticism. (shrink)

"Le Discours de la Méthode" (in English, "Discourse on the Method") is a philosophical work written by the French philosopher and mathematician René Descartes. This work is considered one of the most influential and foundational texts in the history of Western philosophy. Descartes wrote the "Discourse on the Method" in 1637, and it serves as an introduction to his more comprehensive works, including "Meditations on First Philosophy." The "Discourse" presents Descartes' method of critical thinking and skepticism, (...) which he famously expressed in the statement "Cogito, ergo sum" or "I think, therefore I am." This work is a key contribution to the development of modern philosophy and the Enlightenment. In the "Discourse," Descartes outlines his approach to acquiring knowledge based on reason and doubt, which had a profound impact on the future of philosophy and science. (shrink)

This paper clarifies the philosophical connection between Al-Ghazali and Descartes, with the goal to articulate similarities and differences in their famous journeys from doubt to certainty. As such, its primary focus is on the chain of their reasoning, starting from their conceptions of truth and doubt arguments, until their arrival at truth. Both philosophers agreed on the ambiguous character of ordinary everyday knowledge and decided to set forth in undermining its foundations. As such, most scholars tend to agree that (...) the doubt arguments used by Descartes and Al-Ghazali are similar, but identify their departures from doubt as radically different: while Descartes found his way out of doubt through the cogito and so reason, Al-Ghazali ended his philosophical journey as a Sufi in a sheer state of passivity, waiting for the truth to be revealed to him by God. This paper proves this is not the case. Under close textual scrutiny and through the use of basic Husserlian-phenomenological concepts, I show that Al-Ghazali's position was misunderstood, thus disclosing his true philosophic nature.

The aim of this dissertation is to provide a critique of the idea that skepticism was the driving force in the development of early modern thought. Historian of philosophy Richard Popkin introduced this thesis in the 1950s and elaborated on it over the next five decades, and recent scholarship shows that it has become an increasingly accepted interpretation. I begin with a study of the relevant historical antecedents—the ancient skeptical traditions of which early modern thinkers were aware—Pyrrhonism and Academicism. (...) Then I discuss the influence of skepticism on three pre-Cartesians: Francisco Sanches, Michel de Montaigne, and Pierre Charron. Basing my arguments on an informed understanding of both ancient Greek skepticism and some of the writings of these philosophers, I contend that it is inaccurate to predominantly characterize Sanches, Montaigne, and Charron as skeptics. To support his thesis about the singular influence of skepticism on early modern thought, Popkin says that René Descartes’ metaphysical philosophy was formed as a response to a skeptical threat and that Descartes ultimately conceded to the force of skepticism. He also argues that David Hume was a Pyrrhonist par excellence. I disagree with Popkin’s claims. I argue that Descartes was not as deeply affected by skepticism as Popkin suggests and that it is inaccurate to characterize Hume as a Pyrrhonist. By offering this critique, I hope to make clear to the readers two things: first, that Popkin’s thesis, though it is both enticing and generally accepted by many scholars, is questionable with regard to its plausibility; second, that the arguments I present in this dissertation reveal that further research into the role of skepticism in early modern philosophy is in order.

I argue that descartes thinks he can be metaphysically certain about each premise in the argument for god's existence, Even before he draws the argument's final conclusion that all his distinct ideas are metaphysically certain. The certainty of the personal premises is secured in the second meditation. The certainty of the causal premises, I argue, Arises from their central role in generating reasons for doubt of the kind that interest descartes.

At least since Descartes's Meditations philosophers in the West have been concerned to defend the rationality of our beliefs from the threat of epistemological skepticism. The idea that there might be nothing which we know, or more radically, which we have even the slightest reason to believe, is one that many philosophers have thought to be deserving of serious attention. It seems somewhat odd, therefore, that there has not been similar attention given to what one might call practical (...) skepticism. Is it not also possible that there is nothing which we have even the slightest reason to do? Of course, there is a sense in which epistemological skepticism might be thought to be the more basic problem. If there is nothing which we have any reason to believe, then it will follow that there is nothing which we have any reason to do. If some proposition is a reason that we have for doing something it must at least be the case that we have some reason to believe that proposition. But is practical skepticism merely a species of epistemological skepticism? I doubt it. (shrink)

This chapter contains section titled: Introduction The Structure of Skeptical Arguments The Arguments of the Ancient Skeptics Reasons for Doubt vs. Reasons for Suspending Judgment Two Puzzles References and Further Reading.

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

The paper aims to prove the hypothesis that Sextus Empiricus’ Neo-Pyrrhonism is significantly influenced by the Cartesian meditation as a genre of philosophizing. It refutes theses about (1) the non-predicativity of Sextus’ language and about (2) Sextus’ epochê as an automatic result of the action of opposite things or statements, and it argues that both Sextus and Descartes distinguish between (a) internal (forced) agreement with clarity and (b) the personal acceptance of this agreement which depends on a volitional decision. (...) Sextus’ recognition of the clarity of appearance as appearance gives Descartes the only chance to refute the skepticism of Sextus, which is invulnerable to external criticism. Therefore, Descartes developed meditation as a special model of purely immanent criticism (the very word “skepticism” is never mentioned in the Meditations), focused on dealing with states of clarity and evidence. The author’s hypothesis is that the key elements to which this model appeals are the “history of a skeptic” set out in Outlines of Pyrrhonism and the conception of skeptical expressions. This hypothesis can be tested further by proving or disproving the thesis that the discourse of I, II, and at least partially of III Meditations is based on the pattern of skeptical expressions, focused on the internal states of the speaker, and not on clarifying the “objective” state of affairs (i.e. not on dogmatic inferences).

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)

This work is a study of Blaise Pascal's Pensees. It proposes to show the way in which Pascal's philosophy of mind---his conception of order and the relation of reason, the emotions, and the will to the self---which emerges from his skepticism, can be used to draw out his views on morality, despite the fragmentary state of the work. The thesis begins with a consideration of the three major philosophical precursors to Pascal's project: Augustine, Montaigne, and Descartes. It continues (...) with an account of order in the Pensees, centering on the heart, the two minds, and the three discontinuous orders, connecting Pascal's views to those of a number of 20th century analytic philosophers. It goes on to consider the order of the body and the order of charity in specific detail, showing how Pascal discusses each of these through a dialectical process that begins in a pre-critical, unreflective state, moves through a first, rational and philosophical, criticism, and finally turns that criticism against philosophy itself. The thesis concludes by briefly considering three figures whose ideas, to some extent, carry on and expand those of Pascal: Rousseau, Maistre, Tocqueville. (shrink)

: In his autobiographical account, the Munqidh min al-Dalāl, al-Ghazālī reflects on his conversion from skepticism to faith. Previous scholarship has interpreted this text as an anticipation of Cartesian positions regarding epistemic certainty. Although the existing similarities between al-Ghazālī and Descartes are striking, the focus of the present essay lies on the different philosophical aims pursued by the two thinkers. It is thus argued that al-Ghazālī operates with a broader notion of the Self than Descartes, because it (...) is inclusive of the body. And it is shown that the two philosophers use completely diverging paradigms. While Descartes models his notion of evidence after mathematical certainty, al-Ghazālī draws his famous 'ilm al-yaqīnī (certain knowledge) from a religious context. (shrink)

This edited collection contains eleven essays on philosophers and political thinkers from the sixteenth to the eighteenth century who wrote on skepticism and toleration. Essays on such well-known philosophers as Descartes, Hobbes, Spinoza, and Locke are combined with treatments of Montaigne, the libertins erudits, the Levellers, Bayle, Diderot, Voltaire, and others to produce a broad consideration of the thought of the early modern period. The editor outlines the themes of the volume in an introductory essay that explains why (...) arguments for toleration derived from skepticism made by early modern writers should be of contemporary interest. Levine argues that traditional arguments for toleration are no longer as convincing as they used to be. For example, the traditional liberal argument based on natural rights has been severely weakened by challenges to the status of those rights, which no longer seem so self-evident to philosophers, at least. Due to the contemporary confusion over the basis for toleration, Levine and his contributors turn to the early modern period, when the issue of principled toleration arose in reaction to the religious and political turmoil of the time, for insights that will accord with our own skeptical times.

Similarly to Husserl’s gradually developing view of the decisive phenomenological questions also his relationship to the philosophy of R. Descartes and to the history of philosophy as a whole underwent several changes. We witness a shift from stressing universal attempt at doubt to misunderstanding of Descarte’s own discovery of ego. Husserl sees Descartes’ methodical skepticism as a crucial historical impulse for articulating his own conception of epoché. Descartes’ methodical skepticism and Husserl’s putting in brackets the (...) general thesis about the existence of the world show the closest parallel between their philosophical doctrines. Further, similarly to Descartes Husserl also aims at reforming the philosophy of his time; in Descartes’ Meditations on first philosophy he finds the way leading to transcendental phenomenology. However, there are also differences in their projects of universal philosophy. While for Descartes the model of his mathesis universalis is mathematical science, Husserl aims – with far reaching consequences – at creating transcendental phenomenology as a strictly scientific philosophy which must offer a fundamental organon to all other sciences and thus enable them to undergo a reform.

Kartezjusz w kwestii intelektualnego doświadczenia i sceptycyzmu Epistemologia Kartezjusza jest zakorzeniona w jego głębokim zainteresowaniu i uznaniu dla tego, co można by nazwać intelektualnym doświadczeniem, lub dokładniej przejrzystym intelektualnym doświadczeniem. To zainteresowanie intelektualnym doświadczeniem, jak mi się wydaje, podzielali inni racjonaliści, Spinoza i Leibniz. W części pierwszej artykułu staram się ulokować fenomen przejrzystego intelektualnego doświadczenia w ramach doktryny Kartezjusza i Spinozy.

This chapter contains section titled: The Skeptic's Undoing Cartesian Certainty.

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

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.

This article contends that there are two formulations of skepticism; one centered upon epistemic investigation, the other centered upon developing the human capacity for judgment, a type of “quasi-religious” quest. The identification of these two easily confused formulations is suggested by an analysis of language usage within skeptical argumentation, supported by briefly analyzing Eric Havelock’s Preface to Plato, and confirmed by an analysis of Descartes. The significance of this confusion, i.e., the lack of progress in finding a solution (...) to the skeptical problem, is demonstrated through a critique of an article written by Barry Stroud.

The paper advances the hypothesis that René Descartes presents a skeptical system of philosophy in Thomas Reid’s reading. There is a sort of ‘involun-tary’ or ‘accidental’ skepticism that results from the adoption by Descartes of both a skeptical method and a skeptical principle. The first section shows to what extent the Cartesian method of doubt – which focuses on the reliability of the faculties of the mind - is a skeptical demand that cannot be satisfied. The second (...) section shows how the principle of the Cartesian system – which establishes that ideas are the immediate objects of the operations of the mind – is not only skeptic but leads exactly and naturally to the most radical form of skepticism, namely, solipsism. The third section discusses the Cartesian sources of the doubt on the existence of external world according to Reid. (shrink)

Early modern philosophers after Ren? Descartes are commonly distinguished as either rationalists or empiricists: rationalists are understood to agree with Descartes that reason is the source of knowledge, while empiricists are seen to emphasize the role of the senses within processes of knowledge acquisition. In recent years, this classic distinction has increasingly come under scrutiny. It is objected that, in its simplicity, the distinction tends to conceal the various cross-categorial influences thinkers of the early modern era had on (...) each other.1 In "The History of Scepticism,"2 Richard Popkin provided an alternative approach to early modern philosophy: instead of focusing on the opposition between the two rival camps of empiricists and rationalists, he tells us to concentrate on "la crisepyrrhonienne,"3 for it is this crisis that lay at the heart of early modern philosophy and preoccupied rationalists as much as empiricists.

Thomas Lennon’s book is an important contribution to Descartes scholarship in that it systematically challenges the standard interpretation of the Meditations, i.e., that Descartes sought to refute skepticism and failed, arguing instead that a notion of intellectual integrity rests at the root of Descartes’s thought. All the while, these aims are accomplished through an analysis of the Censura philosophiae cartesianae by Pierre-Daniel Huet, a skeptic and fierce critic of Descartes.Beyond introducing Huet and his relationship to (...) Cartesians like Pierre-Sylvain Regis and Nicolas Malebranche, chapter one argues that Descartes’s apparent pride, arrogance, and vanity precipitated Huet’s conversion from supporter to avid critic of Descartes. Chapters two though seven further establish Huet’s concern with Descartes’s pride. But Lennon’s deeper aim, after arguing that the standard interpretation is a relatively late invention solidified by Richard Popkin’s The History of Scepticism, is systematically to unravel the standard interpretation by addressing the cogito, doubt, the criterion of truth, circularity, God, etc. In each.

Skepticism is one of the most enduring and profound of philosophical problems. With its roots in Plato and the Sceptics to Descartes, Hume, Kant and Wittgenstein, skepticism presents a challenge that every philosopher must reckon with. In this outstanding collection philosophers engage with skepticism in five clear sections: the philosophical history of skepticism in Greek, Cartesian and Kantian thought; the nature and limits of certainty; the possibility of knowledge and related problems such as perception and (...) the debates between objective knowledge and constructivism; the transcendental method as a response to skepticism and the challenge of naturalism; overcoming the skeptical challenge.

De Pierris offers a reading that unites radical skepticism and normative naturalism as “two equally important and mutually complementary aspects of Hume’s philosophical position”. The “modern theory of ideas” shapes skepticism, and Newtonian methodology is the basis for naturalism. The “modern theory of ideas” holds that evidence for optimal human cognition is grounded in the “immediate acquaintance with ostensive presentations that are or have been given to the mind”. This is the “presentational-phenomenological model of apprehension”. Descartes introduces (...) to the model pure intellectual items, that is, clear and distinct ideas, which have “‘immutable and eternal’ essences or forms” as referents... (shrink)

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

In this book Han Thomas Adriaenssen offers the first comparative exploration of the sceptical reception of representationalism in medieval and early modern philosophy. Descartes is traditionally credited with inaugurating a new kind of scepticism by saying that the direct objects of perception are images in the mind, not external objects, but Adriaenssen shows that as early as the thirteenth century, critics had already found similar problems in Aquinas's theory of representation. He charts the attempts of philosophers in both periods (...) to grapple with these problems, and shows how in order to address the challenges of scepticism and representation, modern philosophers in the wake of Descartes often breathed new life into old ideas, remoulding them in ways that we are just beginning to understand. His book will be valuable for historians interested in the medieval background to early modern thought, and to medievalists looking at continuity with the early modern period. -/- . (shrink)
