In this paper I examine contemporary accounts of noninferential justification in light of what I take to be the Cartesian project of building epistemology on foundations made secure by the impossibility of error. I argue that familiar abstract arguments for foundationalism, by themselves, don’t seem to motivate Cartesianism. But I further argue that there is one version of foundationalism that is more closely linked to the way in which Descartes sought ideal knowledge.

This paper argues that a Cartesian belief in the self-transparency of minds might actually be an innate aspect of our mind-reading faculty. But it acknowledges that some crucial evidence needed to establish this claim hasn’t been looked for or collected. What we require is evidence that a belief in the self-transparency of mind is universal to the human species. The paper closes with a call to anthropologists (and perhaps also developmental psychologists), who are in a position to collect such (...) evidence, encouraging them to do so. (shrink)

Jennifer Windt’s Dreaming is an enormously rich and thorough book, developing illuminating connections between dreaming, the methodology of psychology, and various philosophical subfields. I’ll focus on two epistemological threads that run through the book. The first has to do with the status of certain assumptions about dreams. Windt argues that the assumptions that dreams involve experiences, and that dream reports are reliable — are methodologically necessary default assumptions, akin to Wittgensteinian hinge propositions. I’ll suggest that Windt is quietly pre-supposing some (...) sceptical assumptions, and that recent literature in epistemic externalism may bear in important ways on her arguments. The second thread involves the perennial sceptical worry that dreaming threatens ordinary knowledge. I’ll suggest again that Windt makes tacit sceptical assumptions one may wish to resist. (shrink)

This chapter contains section titled: Pragmatism Redirected From Knowledge Approximated to Approximate Knowledge Technology, Standardization, and Experimental Science Measurement and Orders of Magnitude Non‐Reductionism, Hierarchy, and Complexity Action, Progress, and Moving Beyond Cartesian Intellectualism.

This article reexamines Vico’s early critique of Cartesian reasoning and of how the Cartesian method, which comes from epistemology, creates problems for the sciences once embedded into their methodologies and given a foundational role. The focus will be on De nostri temporis studiorum ratione (1709), where Vico argues against generalizing the Cartesian method and overemphasizing clarity and distinctness in the search for truth. To this end, Vico’s relation to Cartesianism is first carefully contextualized. Then, Vico is (...) presented as a hylomorphist when it comes to how scientific disciplines and their instruments interrelate, something key for understanding why he questions the “instrumentalization” of the Cartesian method in the first place. Afterwards, Vico’s account of the impossibility of maximal scientific progress when the Cartesian method is prioritized across the sciences is presented, as probabilistic reasoning and the importance of the imagination and memory take centerstage. Lastly, the article looks at Vico’s opposition to the geometrical method’s role in physics and his defense of visual thinking in mathematics. The hope throughout is to advance a picture of the early Vico as being not only a neo- Baconian pragmatist, but a hypermodern ”meta-Cartesian” thinker concerned with humanity’s optimizing its creative potential in order to achieve scientific advances.

Descartes’ Rules for the direction of the mind presents us with a theory of knowledge in which imagination, considered as an “aid” for the intellect, plays a key role. This function of schematization, which strongly resembles key features of Proclus’ philosophy of mathematics, is in full accordance with Descartes’ mathematical practice in later works such as La Géométrie from 1637. Although due to its reliance on a form of geometric intuition, it may sound obsolete, I would like to show that (...) this has strong echoes in contemporary philosophy of mathematics, in particular in the trend of the so called “philosophy of mathematical practice”. Indeed Ken Manders’ study on the Euclidean practice, along with Reviel Netz’s historical studies on ancient Greek Geometry, indicate that mathematical imagination can play a central role in mathematical knowledge as bearing specific forms of inference. Moreover, this role can be formalized into sound logical systems. One question of general epistemology is thus to understand this mysterious role of the imagination in reasoning and to assess its relevance for other mathematical practices. Drawing from Edwin Hutchins’ study of “material anchors” in human reasoning, I would like to show that Descartes’ epistemology of mathematics may prove to be a helpful resource in the analysis of mathematical knowledge.

In his influential paper ‘Two Types of Foundationalism,’ William Alston distinguishes two important conceptions of foundationalism: ‘simple foundationalism’ and ‘iterative foundationalism’. SF is the view that there are immediately justified beliefs of some kind or other. IF is the stronger view that certain epistemic propositions are immediately justified. Alston favors a reliability account of immediate justification of the kind defended by externalists such as Armstrong, Dretske, and Goldman. Alston rejects IF by appeal to what he calls the ‘second level argument.’ (...) He claims, further, that since IF is essential to the Cartesian project of reconstructing knowledge, the Cartesian project must be abandoned. (shrink)

Many contemporary social epistemologists take themselves to be combatting an individualist approach to knowledge typified by Descartes. Although I agree that Descartes presents an individualist picture of scientific knowledge, he does allow some practical roles for reliance on the testimony and beliefs of others. More importantly, however, his reasons for committing to individualism raise important issues for social epistemology, particularly about how reliance on mere testimony can propagate prejudices and inhibit genuine understanding. The implications of his views are worked (...) out more fully by some of his immediate successors; I examine how François Poulain de la Barre, and (briefly) Mary Astell analyze the social conditions for epistemic agency in a Cartesian vein.

Descartes’ Meditations raised a serious question about whether he committed a logical fallacy while proving God’s existence and veracity. The crux of the allegation is him saying the truth of the clear and distinct perceptions depend on God’s veracity while its validity rests on some clear and distinct perceptions such as Cogito. At first glance Meditations justify this charge if not been attentively read. Disposal of the Cartesian circle claim depends on showing at least some clear and distinct perceptions (...) are spared from evil demon hypothesis. In this article I will argue that Cogito argument, truth rule and principles of reason specifically causality don’t need divine guarantee to grant their truth. Hence, I will defend that his arguments on proving God’s existence and veracity are circularity-proof. But still metaphysic foundations of Descartes’ epistemology rely substantially on God because without his veracity we are doomed to accept a fatal solipsism and never attain a solid ground for science, especially for physics.

This book develops new techniques in formal epistemology and applies them to the challenge of Cartesian skepticism. It introduces two formats of epistemic evaluation that should be of interest to epistemologists and philosophers of science: the dual-component format, which evaluates a statement on the basis of its safety and informativeness, and the relative-divergence format, which evaluates a probabilistic model on the basis of its complexity and goodness of fit with data. Tomoji Shogenji shows that the former lends support (...) to Cartesian skepticism, but the latter allows us to defeat Cartesian skepticism. Along the way, Shogenji addresses a number of related issues in epistemology and philosophy of science, including epistemic circularity, epistemic closure, and inductive skepticism. (shrink)

This paper defends an interpretation of Descartes according to which he sees us as having normative (and not merely psychological) certainty of all clear and distinct ideas during the period in which they are apprehended clearly and distinctly. However, on this view, a retrospective doubt about clear and distinct ideas is possible. This interpretation allows Descartes to avoid the Cartesian Circle in an effective way and also shows that Descartes is surprisingly, in some respects, an epistemological externalist. The paper (...) goes on to defend this interpretation against some powerful philosophical objections by Margaret Wilson and others by showing how Descartes' doctrine of the creation of the eternal truths can be brought in to support his epistemology. This doctrine and other analogous positions in Descartes can also reveal that Descartes, again surprisingly, takes important steps toward doing epistemology without direct appeal to God and God's veracity.

In various arguments, Descartes relies on the principles that conceivability implies possibility and that inconceivability implies impossibility. Those principles are in tension with another Cartesian view about the source of modality, i.e. the doctrine of the free creation of eternal truths. In this paper, I develop a ‘two-modality’ interpretation of the doctrine of eternal truths which resolves the tension and I discuss how the resulting modal epistemology can still be relevant for the contemporary discussion.

A lucid introduction to the "existential phenomenology" of Martin Heidegger, particularly as developed in his major work, Being and Time, this work focuses on how Heidegger's ideas bear on the central problem in epistemology--that of how we can have objective knowledge. The author constructs fresh arguments clarifying Heidegger's contribution to the theory of knowledge, and shows why Heidegger deemed misguided the search for knowledge of the way things are in themselves.

Cartesian Empiricisms considers the role Cartesians played in the acceptance of experiment in natural philosophy during the seventeenth century. It aims to correct a partial image of Cartesian philosophers as paradigmatic system builders who failed to meet challenges posed by the new science’s innovative methods. Studies in this volume argue that far from being strangers to experiment, many Cartesians used and integrated it into their natural philosophies. Chapter 1 reviews the historiographies of early modern philosophy, science, and Cartesianism (...) and their recent critiques. The first part of the volume explores various Cartesian contexts of experiment: the impact of French condemnations of Cartesian philosophy in the second half of the seventeenth century; the relation between Cartesian natural philosophy and the Parisian academies of the 1660s; the complex interplay between Cartesianism and Newtonianism in the Dutch Republic; the Cartesian influence on medical teaching at the University of Duisburg; and the challenges chemistry posed to the Cartesian theory of matter. The second part of the volume examines the work of particular Cartesians, such as Henricus Regius, Robert Desgabets, Jacques Rohault, Burchard de Volder, Antoine Le Grand, and Balthasar Bekker. Together these studies counter scientific revolution narratives that take rationalism and empiricism to be two mutually exclusive epistemological and methodological paradigms. The volume is thus a helpful instrument for anyone interested both in the histories of early modern philosophy and science, as well as for scholars interested in new evaluations of the historiographical tools that framed our traditional narratives.

In this concise book, one of the world's leading epistemologists provides a sophisticated, revisionist introduction to the problem of knowledge in Western philosophy. Modern and contemporary accounts of epistemology tend to focus on limited questions of knowledge and skepticism, such as how we can know the external world, other minds, the past through memory, the future through induction, or the world’s depth and structure through inference. This book steps back for a better view of the more general issues posed (...) by the ancient Greek Pyrrhonists. Returning to and illuminating this older, broader epistemological tradition, Ernest Sosa develops an original account of the subject, giving it substance not with Cartesian theology but with science and common sense. -/- Descartes is a part of this ancient tradition, but he goes beyond it by considering not just whether knowledge is possible at all but also how we can properly attain it. In Cartesian epistemology, Sosa finds a virtue-theoretic account, one that he extends beyond the Cartesian context. Once epistemology is viewed in this light, many of its problems can be solved or fall away. -/- The result is an important reevaluation of epistemology that will be essential reading for students and teachers.

According to a traditional Cartesian epistemology of perception, perception does not provide one with direct knowledge of the external world. Instead, your immediate perceptual evidence is limited to facts about your own visual experience, from which conclusions about the external world must be inferred. Cartesianism faces well-known skeptical challenges. But this chapter argues that any anti-Cartesian view strong enough to avoid these challenges must license a way of updating one’s beliefs in response to anticipated experiences that seems (...) diachronically irrational. To avoid this result, the anti-Cartesian must either license an unacceptable epistemic chauvinism, or else claim that merely reflecting on one’s experiences defeats perceptual justification. This leaves us with a puzzle: Although Cartesianism faces problems, avoiding them brings a new set of problems. (shrink)

The skeptical doubts entertained by Descartes give rise to seven distinct theses characterizable as solipsistic, each focused on one of three general epistemological problems, that of the reality of the perceived, that of the existence of the unperceived, and the so-called problem of the existence of an external world. The skeptical challenge in each case is concerned not with absolute certainty, but with the question of whether there is any warrant whatever for bridging the evidential gap between data and common-sense (...) tenets. ;The challenge is shown to be answerable neither with pragmatic considerations nor with semantic ones, nor by appeal either to usual perceptual procedures, or to the factual presuppositions of enquiry. Coherentist criteria of fit, consilience, and simplicity are equally uncompelling and irrelevant. Detailed examination shows charges of parasitism, whether self-referential, epistemic, conceptual, or linguistic, to fail against all but one form of Cartesian solipsism, that arising from the external world problem. In particular, it appears not only that the three assumptions of any linguistic parasitism argument, to wit, the ontocentricity of language, the impossibility of private language, and the logocentricity of thought, are each false, but also that solipsistic theses may be formulated either in revised English or in imagic thought. ;The conclusion dictated is that skepticism regarding the reality and existence of everyday objects is answerable only by a rational foundationalist enterprise building on the terrain of the sensuous flux of the radical skeptic. An introspective analysis of instances of thinking, whether non-symbolic, imagic, or linguistic, and of feeling and motivation shows an indispensable element of the thinking subject to be the tactual body. The accommodation of this circumstance makes forms of solipsism questioning the reality of the observed Googolizably arbitrary, and consequently their espousal irrational. Finally, an extrapolation of an inverse probability argument shows forms of solipsism denying the existence of the unobserved to be extremely unlikely to be true. The argument utilizes a method of random selection based on free choice, the one remaining option given the proscriptions against empirical knowledge. (shrink)

Cartesian Truth depicts René Descartes as grappling with the same problem confronting contemporary philosophers: the reconciliation of commonsense realism with a scientific view of the world. Vinci traces modern analytic epistemology back to Descartes, characterizing it as a set of tools Descartes and his successors developed to solve the problems of fusing the manifest and scientific images. Vinci is dissatisfied with contemporary solutions and sees better answers in Descartes’s epistemology.

Epistemological disjunctivism (ED) has been thought to solve the conditionality problem for epistemic externalism. This problem arises from externalists’ characterization of our epistemic standings as conditional on the obtaining of worldly facts which we lack any reflective access to. ED is meant to avoid the conditionality problem by explicating subjects’ perceptual knowledge in paradigmatic cases of perceptual knowledge via their possession of perceptual reasons that are both factive and reflectively accessible. I argue that ED’s account of reflectively accessible factive perceptual (...) reasons is also prey to the conditionality problem. After that, I submit that Stroud’s influential formulation of the conditionality problem relies on a methodological requirement that is potentially dissociable from ED. So, it is possible to put ED in the service of a more modest anti-skeptical strategy. I close by suggesting that this modest anti-skeptical strategy successfully undercuts the underdetermination-based skeptical paradox. Nevertheless, it does not have substantial advantages over some forms of epistemic externalism. (shrink)

René Descartes' Meditations on First Philosophy is his most celebrated philosophical work. The book remains one of the most significant and influential works in epistemology, metaphysics and philosophy of mind in the history of Western philosophy. In this paper I examine the relationship between the various hyperbolic doubts, the dreaming, imperfect creator, and evil demon hypotheses in Meditation I. The paper shows that the "painting analogy" occupies a central position in the First Meditation not only because it effectively links (...) together the hyperbolic doubts, but also because it lays the groundwork for the claim that although it may be impossible for us to know things outside us as our thoughts represent them to be, we can know at least the feature of our thoughts themselves. By raising the necessary doubt about our sensible experience and the corporeal world, the "painting analogy" makes the case for the primacy of the intellectual world. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Philosophy 39.2 (2001) 292-294 [Access article in PDF] Secada, Jorge. Cartesian Metaphysics: The Scholastic Origins of Modern Philosophy. New York: Cambridge University Press, 2000. Pp. xii + 333. Cloth, $59.95. Descartes scholars can welcome this book. Secada supports trends in scholarship that criticize seeing Descartes as merely an anti-skeptical foundationalist, and he challenges many prominent interpretations of Descartes's metaphysics. In addition, Secada helpfully (...) references Scholastic sources to provide context for Descartes's views. This book is also valuable for philosophers in contemporary metaphysics and epistemology. Secada uses the tools and idiom of analytic philosophy to explain and defend Descartes, and he is sympathetic to Descartes's project, even if he grants that aspects of it "are difficult to articulate clearly and convincingly" (174).The book's central theme is the contrast between Descartes's "essentialism" and the "existentialism" of Scholastics. Secada explains the distinction as follows: "Essentialism (existentialism) is the doctrine, first, that one cannot know the existence (essence) of any substance without first knowing its essence (existence), and, secondly, that one can know the essence (existence) of some substance without knowing its existence (essence)" (8). Cartesian Metaphysics interprets Descartes's corpus as a defense of essentialism in the light of Scholastic existentialism.The first three chapters set the stage. Chapter One distinguishes essentialism from existentialism. Chapter Two provides historical background necessary to understand the role of Scholasticism in Descartes's thought. Chapter Three discusses the role of Christian Platonism in both Descartes and the Scholastics, especially their shared Augustinian presupposition that knowledge of essences is of "how things are in themselves" (56).The next three chapters discuss the metaphysical status of ideas. In Chapter Four, Secada contrasts Descartes's "immanent" theory according to which "the immediate objects of ideas must exist in the mind" (85) with the "realist Scholastic" theory that "takes mental acts to be immediately directed towards things" (83). In Chapter Five, this account is applied to an interpretation of the Second Meditation as a defense of intellectualist essentialism against Scholastics and empiricists. "Contrary to the Scholastics and other empiricists, Descartes attributed to the intellect and not to the senses the power to reach the world of substances existing outside of the inner theatre of the mind" (116). Through comparing Descartes with Suarez and Gassendi, Secada argues that all the proofs of existence in the Meditations, including for the cogito, argue from [End Page 292] knowledge of essence to knowledge of existence. Chapter Six turns to Descartes's proofs for the existence of God. According to Secada, even for a posteriori proofs, knowledge of God's existence depends on knowledge of his essence.The last three chapters examine Descartes's theory of substance. Chapter Seven reconstructs Descartes's distinction between substances and properties. A substance is something that "exists without inhering" and "exists uncaused" (185). Secada discusses the nature of substance, how substances other than God can be "uncaused," and the plausibility of Descartes's sharp distinction between substances and properties. The chapter ends by arguing that Descartes's doctrine about the relationship between substances and properties inadvertently "heralds Spinoza's pantheism" (185). Chapter Eight examines real and essential properties in Cartesian metaphysics in contrast to Suarez and Fonseca, and ends with a partial defense of Descartes's ontological argument. Chapter Nine offers a detailed discussion of two fundamental substances in Descartes's metaphysics: body and mind. Secada argues that Descartes offers no satisfactory explanations of body, mind, or the relationship between the two.As is clear from this brief summary, Cartesian Metaphysics is a rich book. It presents important historical details without endless irrelevant details (see especially the sketch of Descartes's Scholastic background on 27-33). The exegetical arguments make strong cases for new interpretations of Descartes. Secada effectively shows that Descartes is more concerned with metaphysics than with refuting skepticism. Comparisons with Suarez and Fonseca shed new light on Cartesian arguments. Reconstructions of Cartesian arguments even tempt one to take Descartes seriously in contemporary metaphysics. And the criticisms of Descartes are thought-provoking.Unfortunately, the... (shrink)

In Laboratory Epistemologies, Jenny Boulboullé examines the significance of hands-on experiences in contemporary life science laboratories. Addressing the relationship between contemplation and manipulation in epistemology, Boulboullé combines participant observations in molecular genetics labs and microbiological cleanrooms with a long durée study of the history and philosophy of science. She radically rereads Descartes' key epistemological text Meditations on First Philosophy, reframing the philosopher as a hands-on knowledge maker. With this reading, Boulboullé subverts the pervasive modern conception of the disembodied knower (...) and puts the hands-on experimenter at the heart of life sciences research. In so doing, she contributes a theoretical model to understanding how life processes on cellular and molecular levels is manually produced in today's techno-scientific spaces. By reassessing the Cartesian legacy and arguing that epistemology should be grounded in the standpoint of a hands-on practitioner, Boulboullé offers the philosophical and historical groundwork to understand and study contemporary life sciences research as multisensory embodied practices.

The period in the history of blood transfusion that I discuss is roughly 1628, the date of publication of Harvey’s work on blood circulation, De Motu Cordis, and 1668, the year of the first allegedly successful transfusion of blood into a human subject by a French physician Jean Denis, and the official order to prohibit the procedure. The subject of special interest in this history is Robert Desgabets, an early defender and teacher of the Cartesian philosophy at St. Maur, (...) in the region of Lorraine, France. Desgabets’ Discourse de la communication ou transfusion du sang Communication or Transfusion of Blood contains a defence and description of the procedure. This three page manuscript is a lecture delivered at one of the meetings held at M. de Montmor in July 1658. Letters and documents which describe the events of these conferences during Desgabets’ eight month stay in Paris in 1658, indicate that he had numerous discussions with the Cartesian physicist Jacques Rohault and also with another leading Cartesian scientist, Gerauld Cordemoy. In addition, Desgabets is said to have frequently attended the meetings where he showed his interest in many scientific questions. I provide evidence that Desgabets was not an arm-chair scientist: he performed experiments, and he designed and created an apparatus to carry out the procedure of blood transfusion. I show how Desgabets’s Cartesian conception of mechanism and body had theological as well as epistemological underpinnings and consequences. For Desgabets, experiments on blood transfusion were as much demonstrations of the truth of the Cartesian metaphysics as they were demonstrations of the possibility of transubstantiation. The role of experiment was to provide demonstrations of the first principles or truths of physics and theology by connecting them to the way God actually made the world. The upshot of Desgabets's treatment of expérience is that it is integral to the knowledge of essences, and hence to the discovery of the truth of things. In placing expérience at the very foundation of true knowledge, Desgabets reconstructs Cartesianism on an empiricist foundation. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Cartesian Truth by Thomas C. VinciTad M. SchmaltzThomas C. Vinci. Cartesian Truth. New York: Oxford University Press, 1998. Pp. xv + 270. Cloth, $45.00.The book jacket copy claims that Cartesian Truth merits “serious consideration by both contemporary analytic philosophers and postmodern thinkers.” Yet the work is written in a decidedly analytic idiom, and it is keyed primarily to recent analytic discussions of [End Page 531] (...) epistemological foundationalism. Moreover, what is most valuable is not its comments concerning the relevance of Descartes to these discussions, but rather its admirably clear rational reconstruction of Descartes’ own epistemology. In fact, this study usefully distinguishes two different but interrelated epistemological theories in Descartes. The first is connected to Descartes’ “project of pure inquiry” (to borrow Bernard Williams’ phrase), a project involving the attempt to derive truths a priori from the “rule of truth,” that is, the rule that whatever one clearly and distinctly perceives is true. The first three chapters of Vinci’s work consider this aprioristic project. The last four chapters focus on the project in Descartes of providing an epistemology of sense experience that allows for nonintellectual knowledge of the material world. Vinci makes some original and insightful claims about these projects and their interconnections.Vinci begins by defending a reading of the rule of truth which requires (roughly) that clearly and distinctly perceived properties exist in a substance either eminently or formally. One may doubt whether Vinci has succeeded in his stated goal of providing a “defense” of this rule (208), especially since he makes no attempt, as far as I can tell, to offer a transcendental argument for the substance/property metaphysic that the rule presupposes on his reading of it. However, this reading does reveal how that rule could provide a foundation for the causal principles that are essential to the argument for the existence of God in the Third Meditation. This discussion thus has the virtue of yielding a solution to the puzzle of why Descartes was so confident that these principles are revealed by the “light of nature.”At the end of chapter 3, Vinci notes a well-known difference between the proof of the existence of the material world in the Sixth Meditation, which appeals to our “natural inclination” to believe that sensations come from bodies, and the version of that proof in the second part of the Principles of Philosophy, which appeals rather to a clear and distinct perception of material properties that is “stimulated by sense.” What is new and interesting in Vinci, however, is an explanation of this difference that appeals to Descartes’ commitment in the latter text to the view that nonintellectual “concrete intuitions” warrant claims concerning the existence of material substance and its properties. Vinci proposes that Descartes came to accept such a view because he adopted a revised version of the rule of truth that dictates that the properties we concretely intuit formally exist in a substance.The second part of his study considers various issues connected to the notion of concrete intuition. There Vinci defends in particular the thesis that Descartes took such intuitions to pertain only to the imagination, and thus to differ in kind from sensations of secondary qualities such as color, temperature, and taste. At times he makes the stronger claim that Descartes “never speaks of sensations” of primary qualities such as “size, shape, and so on” (102). There is, however, a notable counterexample to such a claim in the Comments on a Certain Broadsheet, which lists as innate sensory ideas not only those of pains, colors and sounds but also those of shapes and motions. I found Vinci’s own discussion of this passage (148–51) to be uncharacteristically confused. Nonetheless, one could distinguish between the sensory perception of the extension of, say, a particular colored patch, on the one hand, and the imaginative perception of extension as a common sensible, on the other. One could then conclude, in line with Vinci’s own [End Page 532] position, that Descartes took only the latter sort of perception to count as a concrete intuition, and thus to fall under the revised version of the rule of truth.I have mentioned only...

Bold and pioneering, this book makes a detailed historical and systematic case that Descartes's theory of knowledge is an elegant and powerful combination of a priori, naturalistic, and dialectical elements meriting serious consideration by both contemporary analytic philosophers and postmodern thinkers. In the course of making this case Thomas Vinci develops a broad reinterpretation of Cartesian thought that unlocks novel solutions to many of the most vexed questions in Cartesian scholarship.

There are three well-known models of how to account for perceptual belief within a probabilistic framework: (a) a Cartesian model; (b) a model advocated by Timothy Williamson; and (c) a model advocated by Richard Jeffrey. Each of these models faces a problem—in effect, the problem of accounting for the defeasibility of perceptual justification and perceptual knowledge. It is argued here that the best way of responding to this the best way of responding to this problem effectively vindicates the (...) class='Hi'>Cartesian model. Finally, it is argued that, given the best interpretation of the probabilistic framework, that the Cartesian model is not vulnerable to the main criticisms that have been raised against it. (shrink)

The 17th century author François Poulain de la Barre was an important contributor to a pivotal moment in the history of feminist thought. Poulain borrows from many of Descartes’s doctrines, including his dualism, distrust of epistemic authority, accounts of imagination, and passion, and at least some aspects of his doxastic voluntarism; here I examine how he uses a Cartesian notion of prejudice for an anti-essentializing philosophy of women’s education and the formation of the tastes, talents and interests of individuals. (...) ‘Prejudice’ remains Descartes’s notion of an entrenched, yet self-imposed doxastic commitment, but also takes on the sense of social-political group bias, founded on custom, transmitted through education, serving interests, and forming social expectations. Poulain also expands on the Cartesian notion and themes by emphasizing widespread, yet unjustified social opinions in favor of the status quo in both epistemic practices and epistemic authorities, while considering how biased beliefs about sexual difference and gender identity can be internalized even by those who suffer most from them. At the same time, he shows how powerful Cartesian concepts can be for feminist methodology, even though they might also be put to problematic uses (as Malebranche did). (shrink)

A prominent response is that Cartesian skepticism is too Cartesian. It arises from outmoded views in epistemology and the philosophy of mind that we now properly reject. We can and should move on to other things. §2 takes up three broadly Cartesian themes: the epistemic priority of experience, under-determination, and the representative theory of perception. I challenge some common assumptions about these, and their connection to skepticism. §3 shows how skeptical arguments that emphasize causal considerations can (...) avoid some suspect Cartesian commitments. §4 explores the related idea that perceptual knowledge is what I call instrumental knowledge. Drawing on that connection, §5 examines a skeptical argument based on minimal assumptions, and explains why a Moorean response to it is unsatisfactory. The problem of skepticism is still with us, and it requires a substantive solution. (shrink)

Did Descartes make a revolutionary contribution to philosophy? Given the widespread application to him of the title ‘father of modem philosophy,’ the standard affirmative proves surprisingly difficult to justify. ln this paper I locate Descartes’s epoch-making philosophical shift. Descartes contributed a very strong idea of realism, an idea modelled in his cogito-argument. To grasp the contribution aright, it is however necessary to de-emphasise what is usually identified as his key contribution---an epistemological one. AIso, the theoretical connection between Descartes’s core philosophical (...) activity and the scientific revolution of his time has to be appreciated. ln the course of the discussion I explain, in a more philosophical vein, how the influence of Kant clouds the abiIity of post-Kantians to see what Descartes did. A route to an understanding of Descartes’s realism is an inconsistency in Kant’s modal views. The antirealism of Kant’s view---his transcendental idealism---yields up some of its mystery once the dialectical interplay with Cartesian realism is elicited. (shrink)

The Cartesian skeptic’s strategy is to tell a story about the world that is entirely consistent with all of the empirical evidence that we do, or can, have, but according to which many or all of our ordinary beliefs are false. He then suggests that, since we cannot show that his story is false, we ought to surrender those beliefs. In this paper I offer a decision-theoretic response to skepticism. Say that a cognitive attitude is a propositional attitude that (...) may be true or false. I argue that rejecting the skeptic’s story, and so retaining our ordinary opinions, will yield for us true cognitive attitudes, no matter whether the skeptic’s story is true or false, and that the best any alternative can do is yield no cognitive attitudes at all. Hence, it is rational to retain our ordinary opinions. One may be concerned that I can maintain this surprising conclusion because the cognitive attitudes at issue are not real beliefs, and do not represent the real world. I conclude the paper by arguing that this concern is misplaced. (shrink)

In ' Unnatural Doubts' Michael Williams argues that Cartesian skepticism is not truly an "intuitive problem" (that is, one which we can state with little or no appeal to contentious theories) at all. According to Williams, the skeptic has rich theoretical commitments all his own, prominent among which is the epistemic priority thesis. I argue, however, that Williams's diagnostic critique of the epistemic priority thesis fails on his own conception of what is required for success. Furthermore, in a brief (...) "Afterword" I argue that the later Wittgenstein (to whom Williams sometimes appeals) would concur with my critique of Williams's antiskeptical efforts. (shrink)

I argue that Cartesian skepticism about the external world leads to a vicious regress of skeptical attitudes, the only principled and unproblematic response to which requires refraining from taking the very first skeptical step.

It has become almost a conventional wisdom to argue that Cartesian scepticism poses a far more radical sceptical threat than its classical Pyrrhonian counterpart. Such a view fails to recognise, however, that there is a species of sceptical concern that can only plausibly be regarded as captured by the Pyrrhonian strategy. For whereas Cartesian scepticism is closely tied to the contentious doctrine of epistemological internalism, it is far from obvious that Pyrrhonian scepticism bears any such theoretical commitments. It (...) is argued here that by viewing the Pyrrhonian style of sceptical argument in terms of this contemporary epistemological externalist/internalist distinction one can gain a new insight into some of the more problematic elements of this variety of classical thought and also get a handle on certai contemporary worries that have been raised regarding the anti-sceptical efficacy of externalist theories of knowledge.

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Philosophy 41.2 (2003) 275-276 [Access article in PDF] Zbigniew Janowski. Cartesian Theodicy: Descartes' Quest for Certitude. Dordrecht: Kluwer, 2002. Pp. 181. Cloth, $30.00. Janowski begins this original and erudite work by saying that although "the Meditations have never [before] been interpreted as a theodicy... insofar as theodicy is concerned with examining the relationship between the existence of evil on the one hand and (...) God's omnipotence and benevolence on the other, Descartes's question 'How would the goodness of God not preclude the possibility that nature is deceptive?' is in perfect conformity with, and continues the long tradition of, Christian apologetics" (13). This is not to deny Descartes's primary role in replacing God's causal role in nature with mechanistic science, and his separating religious truth from that of reason. But Descartes also is profoundly concerned with problems of error, evil, God's role in our sins, and Absolute Truth. Janowski is concerned "to show how Descartes' philosophy is derived from the early-seventeenth-century debates over divine and human freedom" by concentrating on the "incongruity between the existence of an omnipotent and benevolent Creator and man's imperfect nature [and] the nature and scope of human freedom" (19). He presents "the problem of error... as the problem of evil; the problem of human will... as the problem of human freedom, and the quest for Certitude... as theodicy, that is, as the vindication of God's goodness and omnipotence" (19-20). His ground for this is his interpretation of Cartesianism as "a kind of epistemological Augustinianism" (20).The view of basic Christian theology is that God is omnipotent and benevolent, and that all his creations are good, so evil is merely the absence of good. According to Descartes, free will makes both error and evil possible. But Augustine says that after the Fall of Man, free will is corrupt and can incline only to evil. So the only good man can do is by way of God's grace, which man cannot resist, for man is not really free to choose between good and evil. But here, Descartes is in disagreement with Augustine. Again, theodicy concerns the problem of the apparent discrepancy between the power of the creator and the imperfections of creation. And the problem is that Descartes's God is an all-powerful being that is absolutely unlimited and creates everything including logical, moral, and legal principles. Descartes's God is not constrained by the principles of non-contradiction (as opposed to St. Thomas's God, who is so constrained). Descartes's argument is that only God is immutable, nothing created is immutable, so no principle created by God, not the Ten Commandments, not the principle of non-contradiction, is immutable.This doctrine of indifferently created eternal truths allies Descartes with the Molinists who argue that God is indifferent in the sense of all powerful, and that humans have a freedom of indifference in that even given grace, they can decide to do either good or evil. This is in opposition to Augustinians and Jansenists who believe that human will corrupted by the Fall of Man can choose only evil until God gives one grace, after which one can choose only good—which, in either case, rules out any notion of freedom of choice between good and evil by an indifferent free will. Descartes believes that we can choose evil even when God gives us grace to choose good. Descartes does follow Augustine in asserting that for God, knowing and willing are the same, in opposition to St. Thomas. But for humans, knowing and willing are separate, and so humans can both err and sin.Descartes's theodicy is that everything depends on God—physics, mathematics, morals, and law. Without God there would be only nihilism. A great difficulty with this doctrine of eternal truths, however, is that it "makes the nature of God completely incomprehensible to man" (102). This is the doctrine of the Hidden God. But in a backhanded way, it saves Descartes's position. He argues that... (shrink)
