Since Descartes, the nature of doubt has played a central role in the development of metaphysics both positively and negatively. Despite this fact, there has been very little discussion centering round the specific nature of doubt which led, for example, to the Cartesian discovery of the cogito. Certainly, the role of doubt has been well recognized: through doubt Descartes arrives at his indubitable first principle. But what can it mean to doubt the existence of (...) the sensible world? This would seem to rest upon the assumption that we have clear and distinct knowledge of the precise nature of what it means to exist and indeed of what it means to be. As it stands, Descartes’ initiates his Meditations upon certain definite assumptions that demand more thorough interrogation. In this paper and presentation, I examine the possible assumptions inherent in the Cartesian method of doubt within the first and second meditation and the manner in which this leads to the discovery of the cogito. I consider a number of essential questions in light of this: What presuppositions lie at bottom to Cartesian doubt? What is the precise nature of metaphysical doubt? What can it mean to doubt the existence of the sensible world? (shrink)

In this paper I argue that Cartesian skepticism about the external world is self-defeating. The Cartesian skeptic holds that we are not justified in believing claims about the external world on the grounds that we cannot rule out the possibility of our being in a radical skeptical scenario. My argument against this position builds upon a critique of Wilson in Analysis, 72, 668–673. Wilson argues that the Cartesian’s skeptical reasoning commits him to mental state skepticism and that (...) this undermines his ability to claim that he is truly skeptical about the external world. I show that Wilson’s argument does not succeed. She is correct that the Cartesian is committed to mental state skepticism. However, she is mistaken in thinking that there is anything incoherent about combining the Cartesian position that one ought to doubt external world claims with doubt about whether one is in fact such a skeptic. I propose an alternative explanation as to why mental state skepticism proves to be the Cartesian’s undoing. I suggest that mental state skepticism leads to epistemic skepticism and that this undermines the Cartesian’s position that belief about the external world is unjustified. (shrink)

This paper attempts some integration of two perspectives on questions about rationality and irrationality: the classical conception of irrationality as sophism and themes from the romantic revolt against Enlightenment reason. However, since talk of "reason" and "the irrational" often invites rigid dualities of reason and its opposites (such as feeling, intuition, faith, or tradition), the paper turns to "intelligence" in place of "reason," thinking of human intelligence as something less abstract, less purely theoretical, and more firmly rooted in practice, including (...) communicative practice. "Intelligence" is "reason" naturalized. -/- . (shrink)

What did Descartes regard as subject to doubt, and what was beyond doubt, in the Meditations? A review of the Objections and Descartes' reactions in the Replies provides some useful clarification, but viewing Descartes' method of doubt in conjunction with his professed theory of knowledge in the Rules for the Direction of the Mind further elucidates his own understanding of the project. In the Rules, Descartes introduces the mind's intuition of "simple natures" as the atomistic basis of (...) all knowledge, its form as well as its content. The simple natures, Descartes claims, can only be understood thoroughly, and I argue that Descartes' doubt in the  Meditations appears not to include doubt of simple natures. A related attempt to link the earlier work to the Meditations by Peter Schouls is considered and criticized; I suggest as an alternative that there are three classes of objects pertaining to the construction of knowledge in the Meditations: a) first principles and concepts that are constituents of other knowledge, intuited and not doubted, nor called 'knowledge' by Descartes; b) what Descartes calls clearly and distinctly perceived knowledge that survives doubt, known through a kind of intuition; and c) science, as remembered collections of clearly and distinctly perceived knowledge. Finally, because the two works do have important dissimilarities, I also consider how differences between the Rules and the Meditations might affect the applicability of the simple natures to the arguments of the Meditations, especially in the light of clues found in the intellectual autobiography of the Discourse on Method.

Just As it is, I believe, a legitimate philosophical enterprise to engage in a “rational reconstruction” of some term or concept in ordinary language, which will, although similar in many ways to the original concept, be a better concept than the original, in that it will, among other things, be free of ambiguities, vagueness and philosophically irrelevant associations of the parent concept, so there is, I believe, a similar enterprise in the history of philosophy. Here, it is legitimate to reconstruct (...) a philosopher's views about some matter the philosopher has written on in such a way as to defend it from certain criticisms so long as the reconstruction remains faithful to the main thrust of the views in question. In particular this is so when the philosopher is acknowledged to be a very great and influential one, and if the criticisms, were they correct, would be inconsistent with the philosopher's acknowledged greatness. The defence of the philosopher from such criticisms is even more legitimate if it can be shown that although the philosopher has written in places in a way that makes the criticism in question seem correct, he has written elsewhere in a way which makes the criticism seem mistaken.

A zombie is a physical duplicates of a human being which lacks consciousness. A ghost is a phenomenal duplicate of a human being whose nature is exhausted by consciousness. Discussion of zombie arguments, that is anti-physicalist arguments which appeal to the conceivability of zombies, is familiar in the philosophy of mind literature, whilst ghostly arguments, that is, anti-physicalist arguments which appeal to the conceivability of ghosts, are somewhat neglected. In this paper I argue that ghostly arguments have a number of (...) dialectical advantages over zombie arguments. I go onto explain how the conceivability of ghosts is inconsistent with two kinds of a priori physicalism: analytic functionalism and the Australian physicalism of Armstrong and Lewis. (shrink)

ABSTRACT Focused upon Descartes’ writings and letters, this paper considers the exponentially-charged relationship between sadness, melancholy, doubt and philosophical inquiry. The first sections examine the relation between sadness in the Cartesian corpus and melancholy as a traditional pathological classification, with both set against a larger seventeenth century intellectual discourse. The letters exchanged between the Princess Elisabeth of Bohemia and the Palatine and Descartes between 1643 and 1649, that is, just prior to the death of the philosopher in 1650, (...) reveal the central paradigm of this particular relationship between sadness and melancholy. The call to use philosophy as a cure against sadness also enters consideration, with the theatrical, artificial nature of the philosophical cure presented as essential not only to Descartes’ relation to sadness, but also to philosophical method in general. The moral aspect of the establishment of mental habits and their emendation by philosophy hence yields central insights into the larger Cartesian project, here viewed as essentially premised upon a medical vocation.

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)

Suppose that in the Meditations Descartes thinks he needs to prove that his clear and distinct perceptions are true. There can be little doubt that if he does think he needs to do this, he thinks that the way to do it is to prove that ‘a non-deceiving God exists’ is true. Now suppose that Descartes does come up with such a proof. Presumably he clearly and distinctly perceives both the premisses and that ‘a non-deceiving God exists’ follows from (...) them. But that will not suffice to prove that ‘a non-deceiving God exists’ is true. For, if there is a problem about whether clear and distinct perceptions are true, then in advance of settling it, there is a problem about whether what is proved merely on the basis of clear and distinct perceptions is true.

The problem of the Cartesian circle, as it is called, has sparked ongoing debate, which intersects several important themes of the Meditations. Discussions of the circle must address questions about the force and scope of the famous method of doubt introduced in Meditation I, and they must examine the intricate arguments for the existence of God and the avoidance of error in Meditations III to V. These discussions raise questions about the possibility of overturning skepticism, once a skeptical (...) doubt has been introduced. More generally, the problem of the circle resonates with recent questions about the foundations of knowledge: Must we be able to validate our methods of reasoning or of knowing before using them? If we must, wouldn't we be forever stuck at the beginning, unable to use our methods of reasoning or of knowing in their own validation? The problem of the Cartesian circle raises general questions about the validation of reason and the possibility of knowledge. This chapter examines the Cartesian circle in the context of Descartes' central project in the Meditations, to secure the foundations of metaphysics. In carrying out this project, Descartes felt the need, or adopted the strategy, of examining the possibility of human knowledge more generally. Such an examination can be interpreted in various ways. Depending on the interpretation given, the roles assigned to the method of doubt and the proofs about God may differ, thereby altering how we see the problem of the circle. We therefore need first to consider Descartes' metaphysical project along with the methods and strategies he adopted in carrying it out. Subsequently, I explain and evaluate several main approaches to the problem of the circle. The chapter concludes with some reflections on the relation of Descartes' metaphysics of knowledge to other prominent positions in the history of philosophy. (shrink)

I put forward a version of the Cartesian Argument from Doubt for mind–body dualism. My version utilizes de re statements, which means that it is not vulnerable to the usual charge of intensional fallacy. The key de re statement is, ‘Body is such that its existence is entailed by Mind’s believing that Body does not exist’, which is false, whereas the respective ‘Mind is such that its existence is entailed by Mind’s believing that Body does not exist’ is (...) true.

Offers a critical assessment of Descartes's arguments for external‐world scepticism. Even granted charitable exegetical concessions, the arguments prove to be neither intuitive nor compelling. The same holds true for contemporary sceptical reasonings in the Cartesian style, including those based on epistemic ‘closure principles’ and our inability to rule out particular sceptical scenarios.

This paper argues for a novel solution to the Cartesian Circle by emphasising the important epistemic role of the Second Meditation and Descartes’ faculty epistemology. I argue that, for Descartes: doubt requires a ‘good reason’ to doubt ; whether a reason qualifies as a ‘good reason’ depends on which faculty produces that reason ; and for distinct metaphysical perceptions from the faculty of the intellect, no other faculty can provide ‘good reasons’ to doubt. The upshot of (...) §2 is that the doubts raised up to the Third Meditation do not apply to the distinct metaphysical perceptions of the intellect, and in particular do not apply to the premises of the proof of the existence of God. I present the role of God as primarily to secure clear and distinct perceptions beyond the intellect, and knowledge of conclusions when those conclusions are no longer being clearly and distinctly perceived. Finally, I give an account of Descartes’ use of ‘ cognoscere ’, ‘ scire ’, and ‘ scientia ’ as three distinct epistemic levels, providing a valuable structure within which one can see the meditator progress.

In On Doubt, Vilém Flusser refines Martin Heidegger's famous declaration that "language is the dwelling of Being." For Flusser, "the word is the dwelling of being," because in fact, in the beginning, there was the word. On Doubt is a treatise on the human intellect, its relation to language, and the reality-forming discourses that subsequently emerge. For Flusser, the faith that the modern age places in Cartesian doubt plays a role similar to the one that faith (...) in God played in previous eras--a faith that needs to be challenged. Descartes doubts the world through his proposition cogito ergo sum, but leaves doubt itself untouched as indubitable and imperious. His cogito ergo sum may have proved to the Western intellect that thoughts exist, but it did not prove the existence of that which thinks: one can eliminate thinking and yet continue being. Therefore, should we not doubt doubt itself? Should we not try to go beyond this last step of Cartesian doubt and look for a new faith? The twentieth century has seen many attempts to defeat Cartesian doubt, however, this doubt of doubt has instead generated a complete loss of faith, which the West experiences as existential nihilism. Hence, the emergent emptying of values that results from such extreme doubt. Everything loses its meaning. Can this climate be overcome? Will the West survive the modern age? (shrink)

Scepticism about external world knowledge is frequently claimed to emerge from Descartes’s dreaming argument. That argument supposedly challenges one to have some further knowledge — the knowledge that one is not dreaming that p — if one is to have even one given piece of external world knowledge that p. The possession of that further knowledge can seem espe-cially important when the dreaming possibility is genuinely Cartesian (with one’s dreaming that p being incompatible with the truth of one’s accompany-ing (...) belief that p). But this paper shows why that Cartesian use of that possi-bility is not at all challenging. It is because that putative sceptical challenge reduces to a triviality which is incompatible with the sceptic’s having de-scribed some further piece of knowledge which is needed, if one is to have the knowledge that p.

In this paper, I provide what I believe to be Descartes's own solution to the problem of the Cartesian Circle. As I argue, Descartes thinks he can have certain knowledge of the premises of the Third Meditation proof of God's existence and veracity (i.e., the 3M-Proof) without presupposing God's existence. The key, as Broughton (1984) once argued, is that the premises of the 3M-Proof are knowable by the natural light. The major objection to this "natural light" gambit is that (...) Descartes identifies the natural light with the faculty of clear and distinct perception, a faculty that cannot be known to be reliable in advance of the 3M-Proof. I explain that Descartes distinguishes between three kinds of clear and distinction perceptions depending on their source; the senses, the imagination, or the intellect. I claim that although the First Meditation is designed to cast doubt on the clear and distinct perceptions of the senses and of the imagination, it is not designed to cast doubt on the clear and distinct perceptions of the intellect. The "natural light" gambit relies on the assumption that the natural light, by which propositions can be certainly known without presupposing knowledge of God's existence, is to be identified with the faculty of *intellectual* clear and distinct perception.

Descartes is well known for his employment of the method of doubt. His most famous work, the Meditations, begins by exhorting us to doubt all our opinions, including our belief in the existence of the external world. But critics have charged that this universal doubt is impossible for us to achieve because it runs counter to human nature. If this is so, Descartes must be either misguided or hypocritical in proposing it. Hume writes:There is a species of (...) scepticism, antecedent to all study and philosophy, which is much inculcated by Des Cartes and others, as a sovereign preservative against error and precipitate judgement. It recommends an universal doubt, not only of all our former opinions and principles, but also of our very faculties… The Cartesian doubt, …were it ever possible to be attained by any human creature would be entirely incurable; and no reasoning could ever bring us to a state of assurance and conviction upon any subject.

While contemporary epistemologists consider Cartesian scepticism as a menacing problematic, it seems that Plato scarcely had any Cartesian doubts about knowledge of the extemal world. In this paper I ask why Plato had this cavalier attitude towards Cartesian scepticism. A quick first explanation is that Plato never conceived the challenge of Cartesian scepticism or at least, if he did, he missed the potential threat to empirical knowledge that such a challenge poses. I argue against this explanation (...) and offer an altemative, more plausible explanation.Very briefly, I claim that Plato grasped both the logical possibility of Cartesian scepticism and its potential threat but remained impervious because of his ontological epistemology. For Plato, the empirical world can hardly be an object of knowledge, just like a dream can hardly be an object of knowledge. But for Plato this is not really worrying because, necessarily, forms must exist and these constitute the truly real world and the tme object of knowledge. What is deeply worrying for Plato is that most people do not realize the 'dreaming' condition of the empirical world and need to be 'waken up' to the intelligible world of the forms by the philosophers-kings.

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.

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)

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)

In lieu of an abstract, here is a brief excerpt of the content:Cartesian Skepticism from Bare PossibilityRobert WachbritIn making his case for skepticism, Peter Unger offers the following exotic case as one which “conforms to a familiar, if not often explicitly artic-ulated pattern or form” of skeptical reasoning: 1 imagine that there is an evil scientist who deceives subjects into falsely believing that there are rocks. Living in a world bereft of rocks, he induces belief in their existence using (...) electrodes implanted into the appropriate parts of the subjects’ brai ns, protoplasm, or systems through which he sends patterns of electrical impulses in accord with his deceptive designs. Unger then offers the following argument, which is supposed to instantiate the pattern or form of this kind of skeptical reasoning:If you know that there are rocks, then you can know that there is no such scientist doing this to you. But no one can ever know that there is no evil scientist who is, by means of electrodes, deceiving him into falsely believing there to be rocks. So... you never know that there are rocks. But of course we have chosen our person, and the matter of there being rocks, quite arbitrarily, and this argument... may be generalized to cover any external matter at all. From this, we may conclude... that nobody knows anything about the external world. 2After presenting this case and articulating its form, Unger claims that “this argument is the same in form as the ‘evil demon’ argument in Descartes’s [End Page 109] Meditations; it is but a more modern, scientific counter-part, with its domain of application confined to matters concerning the external world.” He then proceeds to describe Descartes’s argument as “the most compelling sceptical argument the phil osophical literature has to offer,” calling it in fact “the classical argument for scepticism.” 3These claims may seem a little bit surprising; for it is not obvious, even from the most careful attention to the text, that what is written about the evil demon in the First Meditation constitutes a skeptical argument at all, and the scholarly literature is generally, and perhaps surprisingly, quite confusing about just what is going on at the end of the First Meditation. Further, rather than being exceedingly compelling as Unger thinks, arguments of this form are not only assiduously avoided by Descarte s during his descent into skepticism but are in fact, as I shall argue with some help from Descartes, weak and considerably less compelling than the kind of skeptical challenges Descartes actually offers.My purpose in this paper, then, is to make two related points, one historical and the other philosophical. First, I will try to demonstrate, on the basis of both textual and critical evidence, that Descartes was not offering a (further and final) skeptica l argument when he invented his demon. I will try to exhibit some of the confusions in the scholarly literature about the text of the last three paragraphs of the First Meditation and, by so doing, support Gouhier’s position that the idea of the demon “ha s no metaphysical significance; it is purely a methodological artifice which permits doubt to continue....” 4 Second, I will show that embodied in Descartes’s rejection of this kind of skeptical reasoning is the very reason for its weakness, a weakness that should prevent it from being considered, as Unger considers it, the classical form of skeptical argument. The inventions of the First Meditation still exercise considerable hold on our philosophical imaginations. I hope to show that, at least as far as the demon is concerned, Descartes would have been surprised at some of the most conventional and entrenched scholarly interpretations given his use of it and not at all sympathetic to its employment in a skeptical argument. Lest the demon seem an old and tired subject of philosophical scrutiny, let me beg the reader’s indulgence by promising both a deeper than usual look into the text of the end of the First Meditation and some significant conclusions about Cartesian skepticism that are hardly commonplace and thus neither old nor tired.

Husserl saw the Cartesian critique of scepticism as one of the eternal merits of Descartes’ philosophy. In doing so, he accepted the legitimacy of the very idea of a universal doubt, and sought to present as an alternative to it a renewed, specifically phenomenological concept of self-evidence, making it possible to obtain an unshakable foundation for the edifice of knowledge. This acceptance of the skeptical problem underlies his entire conceptual framework, both before and after the transcendental turn, and (...) especially the immanence/transcendence distinction, i.e., the very basis of intentionality. In taking as its starting point an analysis of perception, the article puts forth a certain number of phenomenological arguments in order to put into question the validity of the skeptical problem and, therefore, of the Husserlian conceptual framework; it defends, in the first place, a disjunctive conception of perception and, in the second place, a holism of experience.

Clear and distinct perception is the centrepiece of Descartes’s philosophy — it is the source of all certainty — but what does he mean by ‘clear’ and ‘distinct’? According to the prevailing approach, what it means for a perception to be clear is that its content has a certain objective property, like truth. I argue instead that clarity is at least partly a subjective, phenomenal quality whereby a content is presented as true to the perceiving subject. Clarity comes in degrees. (...) Any weak degree of clarity, available to the senses, can be merely subjective, since what it presents as true may not actually be true. But complete clarity, available to intellectual perception, has an objective dimension, since what it presents as true is always some truth, some bit of reality. Further, I argue that the other perceptual qualities that Descartes identifies — obscurity, confusion, and distinctness — are all defined in terms of clarity. Of particular note is the fact that distinctness is not a positive feature to be added to clarity: a distinct perception is just a completely clear perception. (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.

The most frequently discussed skeptical arguments in the history of philosophy are to be found in the tightly argued twelve paragraphs of Descartes’ Meditation One. There is considerable controversy about how to interpret the skeptical arguments that Descartes offers; the extent to which those arguments rest upon implicit epistemological and/or metaphysical presuppositions; their originality within the history of skepticism; and the role they play within Cartesian philosophy and natural science. This chapter begins by tracing the complex argumentation of Meditation (...) One. The second section explores the differences between Cartesian skeptical arguments and the skeptical arguments discussed in the ancient world, while the third section considers whether there might be medieval antecedents for the radical doubts that end Meditation One. The final section suggests that the radical nature of the doubts raised in Meditation One has its sources in two fundamental characteristics of Cartesian science: the radical error that Cartesian science posits in our everyday experience of the world, and the hypothetical and (only) morally certain nature of the scientific edifice that is proposed to replace the commonsense view of the world enshrined in Aristotelian science.

There are several paradigms of 'first philosophy' (e.g. Aristotle, Descartes). A third paradigm of first philosophy is transcendental pragmatics or transcendental semiotics (exemplified by Peirce and Wittgenstein). Husserl correctly grasped that Descartes inaugurated first philosophy in the sense of a transcendental inquiry into the foundations of absolute knowledge. But Husserl's retrieval of Descartes remains within the second paradigm in that it ignores the role of language as a condition of the possibility of objectively constituted knowledge. I propose to re-examine Descartes's (...) conception of first philosophy to see if it can be read in the light of the third paradigm of transcendental philosophy, namely transcendental semiotics. I argue that Cartesian methodic doubt can be rehabilitated (against Wittgenstein's critique) as a kind of 'fallibilistic' approach to knowledge of a Peircean kind, and that the Cartesian cogito can be read (following Hintikka) as recognition of performative contradiction and of the necessity of speech acts, and hence of the transcendental communication community.

This essay contrasts Descartes with three skeptical figures: the Doubting Pyrrhonist, the Agrippan Pyrrhonist, and the Cartesian Skeptic. It argues that the meditator in Descartes’s Meditations is different from all three of these skeptics. Seeing the distinctive character of the meditator helps us understand how Descartes could have hoped to meet the challenge of skepticism.

How do you know anything is true? What relation is there between my psyche and your psyche, does one exist? Can we doubt everything or are some things indubitable? What does Jung have to say about body and psyche, body and mind? Cartesian Philosophy and the Flesh is an analysis and critique of interpretations of Cartesian philosophy in analytical psychology. It focuses on readings of Descartes that have important implications for understanding Jung, and analytical and existential psychology (...) generally. Frances Gray's book raises questions about the 'place' of the body in a theory of the human psyche and about what kind of psyche, if any, is essential to concepts of human being. Gray claims that the debates around Descartes and metaphysical dualism have been oversimplified and that this has had a profound effect on conceptualizing an on-going relation between psyche and body. The book also explores the relationship between Jung's conception of the phenomenological standpoint and that of Edmund Husserl and Maurice Merleau-Ponty. Cartesian Philosophy and Flesh brings together Descartes’ idea of self-interrogation and self-reflection and Jung's project in The Red Book, the practice of spiritual exercises is the underpinning orientation of both men. It recommends similar practices to anyone interested in the truths of their own living. Gray’s book will be of interest to Jung scholars, and those with an interest in Jungian studies, Analytical Psychologists and Philosophers. (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...

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.

The first article of the cycle “The role of skeptical evidence in the First and Second ‘Meditations’” compares the Cartesian and Sextus Empiricus’ concepts of doubt in, respectively, “Metaphysical meditations” and “Outlines of Pyrrhonism”. The article starts with the current state of the problem “Descartes and skepticism” and admits the existence of consensus about Cartesian perception of skeptical tradition: Cartesius (1) was influenced by all skeptical movements, known in his time, and (2) created a generalized notion that (...) contains elements of both Academic and Pyrrhonian origin. This consensus is the source of many contemporary studies on how different skeptical doctrines influenced certain parts of Cartesian philosophy. This article attempts to analyze possible Descartes’ use of Sextus Empiricus’ notion of phenomenon. Sextus clearly states in “Outlines of Pyrrhonism” that one cannot doubt phenomenon as something perceived directly. The article proves that (a) Sextus’ thesis about the “sensory” nature of phenomenon is metaphorical, so far as it includes (without distinction) both sensuality and the experience of thinking; (b) the phenomenon is realized through a wide range of passive states of mind that all have irresistible force of influence; (c) the impact of phenomena is always mediated by our self, because all skeptical phrases are strictly correlated with the first person singular. Some researchers distinguish Sextus’ isostenia, as one of such insurmountable states, from Cartesian doubt at the First Meditation, which is allegedly based on a purely volitional decision. The article proved that this argument is artificial, since Descartes’ volitional decision is caused by initial inability to take the dubious as if it were certain. Thus, Cartesian approach can be considered a specific kind of isostenia. Such parallelism is a reason to assume a key role of Sextus’ understanding of insurmountable power of phenomena in Cartesian anti-sceptical argumentation. This assumption will be tested in the following articles of the cycle. (shrink)

Kirsten Besheer has recently considered Descartes’ doubting appropriately in the context of his physiological theories in the spirit of recent important re-appraisals of his natural philosophy. However, Besheer does not address the notorious indubitability and its source that Descartes claims to have discovered. David Cunning has remarked that Descartes’ insistence on the indubitability of his existence presents “an intractable problem of interpretation” in the light of passages that suggest his existence is “just as dubitable as anything else”. However, although the (...) cogito argument is widely thought to be central to the force of Descartes’ indubitability, for his part, Cunning does not consider its relevance and force. Accordingly, this article is concerned with the cogito argument and the question central to Hintikka’s seminal contribution, described by Cottingham as “Perhaps the most debated question,” namely, whether or not the cogito can be construed as a logical inference. Clearly, an inferential account has the potential to explain the certainty of Descartes’ conclusion that he exists. Recently, Sarkar offers what he characterizes as “novel and fairly conclusive reasons why the cogito cannot be construed as an argument,” asserting “the discovery of the cogito can only be an intuition not a deduction.” Obviously, it would greatly support the opposing inferential construal if a remotely plausible logical argument could be proposed. Toward this end, I defend the virtues of my ‘Diagonal’ account of Descartes’ cogito Above all, I show how my analysis meets the requirement that any satisfactory solution to the problem of the cogito would reconcile Descartes’ claim that the cogito is a certain inference with his claim that it is an intuitive kind of knowledge. Through a critical discussion of analyses such as that of Gallois , I show that it is possible to provide a textually faithful analysis that permits seeing the cogito as both inference and intuition because it may be seen as an exercise in the mathematical method of Analysis. Above all, as Feldman requires, I show that the Diagonal account is not only textually elegant, but permits crediting Descartes with a worthy insight, thereby resolving the tension between what Howell has termed the Humean and Cartesian problems, namely, the elusiveness and the certainty of the self.

This paper suggests that the appearance of circularity in descartes' arguments is due to a lack of precision in his statements of them, Rather than to any flaw in his reasoning. The clear and distinct perceptions presupposed in the demonstrations of the existence of God are not the same as those whose reliability depends upon the existence of god. He is presupposing the reliability only of those clear and distinct perceptions which are known through the light of nature and have (...) metaphysical certainty in that they cannot be imagined false even on the demon hypothesis. And the only clear and distinct perceptions whose reliability he is demonstrating are those which are not known through the light of nature with metaphysical certainty but are subject to metaphysical doubt on the demon hypothesis, Even though they have moral or psychological certainty.
