In this paper, I consider Descartes’ Sixth Meditation dropsy passage on the difference between the human body considered in itself and the human composite of mind and body. I do so as a way of illuminating some features of Descartes’ broader thinking about teleology, including the role of teleological explanations in physiology. I use the writings on teleology of some ancient authors for the conceptual (but not historical) help they can provide in helping us to think about the (...) Sixth Meditation passage. From this, I draw several points, most notably that the Sixth Meditation passage is primarily concerned with the natures of body and composites, and that the issue of teleological explanation is derivative of this primary interest. So, we – and Descartes – must come to terms with what he takes the nature of the composite to be such that it has an intrinsic end-referred nature which grounds teleological explanations. I consider three possibilities: the human composite is a third type of substance – a hylomorphic substance; there is a sort of “satisfaction” relationship between mind and body (each of which retains its own distinct nature in the composite) such that the mind confers teleological value on the body; and there is a sort of “satisfaction” relationship between mind and body (each of which retains its own distinct nature in the composite) such that the mind recognizes teleological value in the body. None of these interpretations is without problems. So in the concluding section, I sketch a program for future research, specifically, trying to render Descartes’ teleological thinking consistent by distinguishing between the metaphysical natures of things (the concern of his Sixth Meditation passage) and the physical natures of things (his concern in his physiological writings).

Harry Frankfurt has argued that Descartes’s madness doubt in the First Meditation is importantly different from his dreaming doubt. The madness doubt does not provide a reason for doubting the senses since were the meditator to suppose he was mad his ability to successfully complete the philosophical investigation he sets for himself in the first few pages of the Meditations would be undermined. I argue that Frankfurt’s interpretation of Descartes’s madness doubt is mistaken and that it should be (...) understood as playing the same role as his more famous dreaming doubt. I focus my discussion around four questions: (Q1) What does the meditator have in mind when speaking of madness?, (Q2) Why does the meditator so quickly dismiss the madness doubt but take seriously the dreaming doubt?, (Q3) Does the madness doubt have the same scope as the dreaming doubt?, and (Q4) Why does the meditator bring up the madness doubt at all?

This chapter examines the mechanistic psychology of Descartes in the _Passions_, while also drawing on the _Treatise on Man_. It develops the idea of a Cartesian “psychology” that relies on purely bodily mechanisms by showing that he explained some behaviorally appropriate responses through bodily mechanisms alone and that he envisioned the tailoring of such responses to environmental circumstances through a purely corporeal “memory.” An animal’s adjustment of behavior as caused by recurring patterns of sensory stimulation falls under the notion (...) of “learning,” behavioristically conceived. Indeed, Descartes’s animal-machine hypothesis may well be a distant ancestor to Watsonian behaviorism, via T. H. Huxley (1884). The final two sections of the chapter take stock of what psychological capacities Descartes ascribed to mind, body, or both, and consider those capacities that we might now plausibly construe as being explicable by nonmentalistic mechanisms as opposed to those that at present remain unreducedly mentalistic. -/- This chapter derives from a lecture delivered at the University of King's College (Halifax, Nova Scotia) as part of a year-long series on Descartes and the Modern. The lecture series was co-sponsored by the programs in History of Science and Early Modern and Contemporary Studies. (shrink)

My thesis is that Descartes wrote the Discours as a plan for a universal science, as he originally entitled it. I provide an interpretation of his letters that suggests that after Descartes began drafting his Dioptrics, he started developing a system that incorporated his early treatises from the 1630s: Les Méteores, Le Monde, L’Homme, and his 1629 Traité de métaphysique. I argue against the mosaic and autobiographic interpretations that claim these were independent treatises or stages in Descartes’ (...) life. Rather, I hold that threat of condemnation concerning his heliocentric thesis resulted in him suppressing his larger project and, instead, he published a plan where he outlined his ongoing system of philosophy. (shrink)

In the _Meditations_ and related texts from the early 1640s, Descartes argues that the self can be correctly considered as either a mind or a human being, and that the self’s properties vary accordingly. For example, the self is simple considered as a mind, whereas the self is composite considered as a human being. Someone might object that it is unclear how merely considering the self in different ways blocks the conclusion that a single subject of predication—the self—is both (...) simple and composite, which is contradictory. In response to this objection, this paper develops a reading of Descartes’s various ways of considering the self. I argue that the best reading of Descartes’s qualified claims about the self, i.e., about the self _qua_ mind or the self qua human being, presupposes an account of the unqualified self, that is, of the self _simpliciter_. I argue that the self _simpliciter_ is not a mind, and that it is not a human being either. This result might suggest the pessimistic conclusion that Descartes’s view of the self is incoherent. To avoid this result, I introduce a new metaphysical account of the Cartesian self. On my view, the self is individuated by a unified mental life. The self is constituted by the beings that jointly produce this mental life, and derives its unity from it. (shrink)

In this paper, I join the so-called voluntarism debate on Descartes’s theory of will and judgment, arguing for an indirect doxastic voluntarism reading of Descartes, as opposed to a classic, or direct doxastic voluntarism. More specifically, I examine the question whether Descartes thinks the will can have a direct and full control over one’s suspension of judgment. Descartes was a doxastic voluntarist, maintaining that the will has some kind of control over one’s doxastic states, such as (...) belief and doubt. According to a long-held reading, the control that the will has over doxastic states in Descartes’s theory is direct; the doxastic states are affected by the mere act of will. This reading is called direct doxastic voluntarism (DDV), or direct voluntarism (DV) for short, and it states that we are capable of assenting, rejecting and suspending a judgment based only on our will to do so. Thus, these actions would be utterly and merely volitional. DV can be divided into two further positions, direct positive voluntarism (+DV) and direct negative voluntarism (-DV). Direct positive voluntarism deals with the act of forming judgments, maintaining that one can accept or deny a proposition wilfully and either merely believe or not believe something voluntarily. Direct negative voluntarism deals with the suspension of judgment, maintaining that it can likewise be accomplished by a simple act of will. However, I support an alternate account of Descartes’s voluntarism, which is called indirect doxastic voluntarism (IDV), or indirect voluntarism (IV) for short. By this account, the will is capable of affecting a doxastic state indirectly by making one concentrate on essential tasks for forming that state, such as gathering up and paying attention to strong reasons and evidence. IV is also possible to divide into indirect positive voluntarism (+IV) and indirect negative voluntarism (-IV). Per indirect positive voluntarism the will needs to pay attention to reasons for accepting or denying some proposition. Likewise, by indirect negative voluntarism, in order to suspend judgment the will needs to direct this attention to the reasons for doubt. By attending to these reasons, the will also comes face-to-face with its own freedom. This feeling of freedom can be described as affectivity of the reasons for belief (assent) and doubt (suspension). (shrink)

Philosophy and Memory Traces defends two theories of autobiographical memory. One is a bewildering historical view of memories as dynamic patterns in fleeting animal spirits, nervous fluids which rummaged through the pores of brain and body. The other is new connectionism, in which memories are 'stored' only superpositionally, and reconstructed rather than reproduced. Both models, argues John Sutton, depart from static archival metaphors by employing distributed representation, which brings interference and confusion between memory traces. Both raise urgent issues about control (...) of the personal past, and about relations between self and body. Sutton demonstrates the role of bizarre body fluids in moral physiology, as philosophers from Descartes and Locke to Coleridge struggled to control their own innards and impose cognitive discipline on 'the phantasmal chaos of association'. Going on to defend connectionism against Fodor and critics of passive mental representations, he shows how problems of the self are implicated in cognitive science. (shrink)

This paper contests a standard interpretation of how Descartes comes to the conclusion that he is not his body in the second meditation. I propose an alternative interpretation in its place.

This paper investigates Descartes’s understanding of the imago Dei, that it is above all in virtue of the will that we bear the image and likeness of God. I challenge the key assumption of arguments that hold that Descartes’s comparison between the human will and the divine will is problematic—that in his conception of the imago Dei Descartes is alluding to Scholastic conceptions of analogy available to him at the time, which would place particular constraints on the (...) legitimacy of the comparison. I argue instead that Descartes is evoking a different tradition regarding the nature of image and imitation, stemming from Augustine and Aquinas, and thus, that those constraints do not apply. I then argue that Descartes thinks the likeness between the human will and God’s will is that both are infinite in “extent.” This means that human will can “extend itself” not only to things that can be the object of some other will, but to things that can be the object of God’s will. This is notable because Descartes famously thinks that absolutely anything can be the object of God’s will. I explain why this interpretation is not implausible, contrary to first appearances. (shrink)

Descartes is widely portrayed as the arch proponent of “the epistemological transparency of thought” (or simply, “Transparency”). The most promising version of this view—Transparency-through-Introspection—says that introspecting (i.e., inwardly attending to) a thought guarantees certain knowledge of that thought. But Descartes rejects this view and provides numerous counterexamples to it. I argue that, instead, Descartes’s theory of self-knowledge is just an application of his general theory of knowledge. According to his general theory, certain knowledge is acquired only through (...) clear and distinct intellection. Thus, in his view, certain knowledge of one’s thoughts is acquired only through clear and distinct intellection of one’s thoughts. Introspection is a form of intellection and it can be clear and distinct. Ordinarily, however, introspection isn’t clear and distinct but is instead confused with dubitable perceptions of bodies. To make introspection clear and distinct, we need to “sharply separate” it from all perceptions of bodies by doubting all perceptions of bodies. Without such radical doubt, introspection remains confused and we lack certain knowledge not just of the specific features of our thoughts, but even of the minimal claim that a thought exists. Far from being the high priest of Transparency, Descartes is radically opposed to it. (shrink)

Descartes claims that the passions of the soul are “all in their nature good” even though they exaggerate the value of their objects, have the potential to deceive us, and often mislead us. What, then, can he mean by this? In this paper, I argue that these effects of the passions are only problematic when we incorrectly take their goodness to consist in their informing us of harms and benefits to the mind-body composite. Instead, the passions are good in (...) their motivational function, which they carry out by representing objects and situations as having various properties and thereby appearing to be “reasons of goodness.” Further, I argue that the main way in which the passions are problematic is merely an occasional physiological byproduct of a well- functioning system. I show, therefore, that the passions’ motivational function, representationality, and accompanying physiology are all significant and interrelated aspects of their goodness. (shrink)

Spinoza’s Principles of Cartesian Philosophy is often presented simply as an interpretation of Descartes’ Principia that does not reveal anything significant about Spinoza’s philosophy and its development. This paper, however, shows that Spinoza altered Descartes’ text in a way congruent with what he would later write in his Theological Political Treatise and the Ethics. More precisely, this paper concentrates not on what Spinoza added to Descartes’ texts but on how he presented them. The paper furthermore examines questions (...) that were obviously important for Descartes but absent in Spinoza’s interpretation. Finally, this paper examines two concrete examples to show that Spinoza’s adaptations function as an unmasking of Descartes’ physics. (shrink)

An early modern scholastic conception of moral possibility helps make sense of Descartes's own perplexing use of that concept and solves the exegetical puzzles surrounding Descartes's conflicting remarks about free will.

This essay offers an interpretation of Descartes’ treatment of the concepts of place and space in the Principles of Philosophy. On the basis of that interpretation, I argue that his understanding and application of the concept of space supports a pluralist interpretation of Descartes on extended substance. I survey the Scholastic evolution of issues in the Aristotelian theory of place and clarify elements of Descartes’ appropriation and transformation thereof: the relationship between internal and external place, the precise (...) content of the claim that space and body are really identical, and the way we conceptually distinguish space from body. Descartes applies his concept of space in ways that illuminate the metaphysical structure of extension. In particular, he uses the concept to specify the degree to which finite parts of matter are independent of each other. I argue that for Descartes, conceiving extension as indivisible is an artifact of conceiving it as a space. That is, pace the monistic reading of Cartesian extended substance, regarding extension as indivisible is an artifact of conceiving it in a way more removed from its real nature. (shrink)

In Philosophy and the Mirror of Nature (1979), Richard Rorty locates the perceived ills of modern philosophy in the "epistemological turn" of Descartes and Locke. This chapter argues that Rorty's accounts of Descartes' and Locke's philosophical work are seriously flawed. Rorty misunderstood the participation of early modern philosophers in the rise of modern science, and he misdescribed their examination of cognition as psychological rather than epistemological. His diagnostic efforts were thereby undermined, and he missed Descartes' original conception (...) of a general physics, and Locke's probabilist analysis of the grounds for rational belief. (shrink)

Commentators commonly assume that Descartes regards it as a function of the passions to inform us or teach us which things are beneficial and which are harmful. As a result, they tend to infer that Descartes regards the passions as an appropriate guide to what is beneficial or harmful. In this paper I argue that this conception of the role of the passions in Descartes is mistaken. First, in spite of a number of texts appearing to show (...) the contrary, I argue that Descartes does not regard it as the role of the passions to inform us about what is beneficial or harmful. Second, although Descartes calls the passions good and useful, I argue that Descartes does not think we should allow ourselves to be guided by them. When we recognize that the function of the passions is largely motivational and not informative, we can more easily understand Descartes's practical advice in The Passions of the Soul that happiness requires us to guide our passions instead of letting our passions guide us.

This is a reply to Vincent Carraud/René Verdon « Remarques circonspectes sur la mort de Descartes » (published in Revue du dix-septième siècle, n° 265, 2014/4, pp. 719-726, online: http://www.cairn.info/revue-dix-septieme-siecle-2014-4-page-719.htm, containing a critique of my "L'énigme de la mort de Descartes" Paris, 2011). I discuss the fatal illness and the death of Descartes, arguing that Descartes was very probably the victim of arsenical poisoning. The suspected murderer is a French priest, François Viogué, living with Descartes (...) in 1650 at the French embassy in Stockholm who may have seen in Descartes an obstacle to the hoped for conversion of queen Christina of Sweden. As against Carraud/Verdon I stress the medical facts, in particular the fact that Descartes himself seems to have suspected poisoning, since he asked for an emetic shortly before his death. (shrink)

I critically examine the view that Descartes’s independence conception (IC) of substance plays a crucial role in his “separability argument” for substance dualism. I argue that IC is a poisoned chalice. I do so by considering how an IC-based separability argument fares on two different ways of thinking about principal attributes. On the one hand, if we take principal attributes to be universals, then a separability argument that deploys IC establishes a version of dualism that is unacceptably strong. On (...) the other hand, if we take principal attributes to be tropes, then IC introduces challenges which undermine the argument. This is partly because the assumption of tropes makes it possible to distinguish several versions of substance dualism, versions which differ with respect to their degree of generality. I argue that taking principal attributes to be tropes makes it challenging to establish any of these versions by way of an IC-based separability argument. I conclude the paper by suggesting a way forward for the proponent of the separability argument. (shrink)

This paper presents a new approach to resolving an apparent tension in Descartes’ discussion of scientific theories and explanations in the Principles of Philosophy. On the one hand, Descartes repeatedly claims that any theories presented in science must be certain and indubitable. On the other hand, Descartes himself presents an astonishing number of speculative explanations of various scientific phenomena. In response to this tension, commentators have suggested that Descartes changed his mind about scientific theories having to (...) be certain and indubitable, that he lacked the conceptual resources to describe the appropriate epistemic attitude towards speculative theories, or that the presence of geometrical principles in these explanations guarantee their certainty. I argue that none of these responses is satisfactory and suggest a different resolution to the tension by examining Descartes’ notion of explanation. On Descartes’ view, providing an adequate explanation does not require being certain of the theories that constitute the explanans. Relatedly, the purpose of Cartesian explanations is not to discover the truth about the various underlying mechanisms that such explanations appeal to, but to support his general philosophical thesis that all natural phenomena can be explained by appealing to the extension of matter.

Many critics, Descartes himself included, have seen Hobbes as uncharitable or even incoherent in his Objections to the Meditations on First Philosophy. I argue that when understood within the wider context of his views of the late 1630s and early 1640s, Hobbes's Objections are coherent and reflect his goal of providing an epistemology consistent with a mechanical philosophy. I demonstrate the importance of this epistemology for understanding his Fourth Objection concerning the nature of the wax and contend that Hobbes's (...) brief claims in that Objection are best understood as a summary of the mechanism for scientific knowledge found in his broader work. Far from displaying his confusion, Hobbes's Fourth Objection in fact pinpoints a key weakness of Descartes's faculty psychology: its unintelligibility within a mechanical philosophy. (shrink)

As a practicing life scientist, Descartes must have a theory of what it means to be a living being. In this paper, I provide an account of what his theoretical conception of living bodies must be. I then show that this conception might well run afoul of his rejection of final causal explanations in natural philosophy. Nonetheless, I show how Descartes might have made use of such explanations as merely hypothetical, even though he explicitly blocks this move. I (...) conclude by suggesting that there is no reason for him to have blocked the use of hypothetical final causes in this way. (shrink)

This essay is a critical assessment of Sellars' interpretation and criticism of Descartes. It argues that Sellars made several mistakes in his view of Descartes, although the general thrust of his critique is sound.

This paper offers a novel interpretation of Descartes's conception of freedom that resolves an important tension at the heart of his view. It does so by appealing to the important but overlooked distinction between possessing a power, exercising a power, and being in a position to exercise a power.

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.

Descartes was both metaphysician and natural philosopher. He used his metaphysics to ground portions of his physics. However, as should be a commonplace but is not, he did not think he could spin all of his physics out of his metaphysics a priori, and in fact he both emphasized the need for appeals to experience in his methodological remarks on philosophizing about nature and constantly appealed to experience in describing his own philosophy of nature. During the 1630s, he offered (...) empirical support for the basic principles of his natural philosophy, while also promising to provide a metaphysical justification. He offered the metaphysical justification in the Meditations and Principles. and claimed absolute certainty for it. At the same time, he recognized that the particular postulated mechanisms of his natural philosophy did not reach that standard of certainty. These mechanisms were supported by empirical testing or confirming of causes through observed effects. (shrink)

Descartes's approach to practical judgments about what is beneficial or harmful, or what to pursue or avoid, is almost exactly the opposite of his approach to theoretical judgments about the true nature of things. Instead of the cautious skepticism for which Descartes is known, throughout his ethical writings he recommends developing the habit of making firm judgments and resolutely carrying them out, no matter how doubtful and uncertain they may be. Descartes, strikingly, takes irresolution to be the (...) source of remorse and repentance, of vice, and of a weak soul. In order to explain its dangerousness, this essay offers an analysis of irresolution as a failure of the will to determine itself to follow a judgment in the face of ignorance or uncertainty. This analysis connects irresolution to weakness of will and explains why Descartes regards resolution as an essential component of virtue. (shrink)

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

Après avoir consacré à Descartes de nombreuses études, parmi lesquelles les monumentales L’homme des passions (Albin Michel, 1995) et Les Méditations métaphysiques de Descartes (PUF, 2005), ainsi que, plus récemment, Le style de Descartes (Manucius, 2013), Denis Kambouchner nous offre Descartes n’a pas dit. Ce livre contient un errata des propos prêtés à Descartes dans l’enseignement, dans les représentations collectives, dans des publications généralistes ou même dans certains travaux spécialisés, et propose de corriger quelques-unes des (...) erreurs les plus sérieuses. D’après Kambouchner, la philosophie cartésienne, en réalité très nuancée et raffinée, est régulièrement victime de simplifications excessives. (shrink)

Descartes argues that, apart from the existence of a veracious God, we can have no reason to believe that we possess reliable cognitive faculties, with the result that, if atheism is true, not even our seemingly most certain beliefs can count as knowledge for us. Since the atheist denies the existence of God, he or she will be precisely in this position. I argue that Descartes' argument is sound, and that atheism is therefore self-refuting.

The Cambridge Descartes’ Meditations—A Critical Guide, a recent addition to the numerous companion texts, guidebooks, introductions and commentaries already available, aims to provide novel approaches to important themes of Descartes’ Meditations by combining contextualism and analysis (of arguments). Organized in four parts (Skepticism, Substance and Cause, Sensations, and The Human Being), the volume contains contributions from (mainly) established scholars of Early Modern Philosophy.

What is, after all, the famous method of Descartes? The brief and vague passages devoted to this subject in Descartes’ corpus have always puzzled his readers. In this paper, I investigate not only the two essays in which it is directly addressed (the Regulae ad Directionem Ingenii, and the Discours de la Méthode), but also his scientific works and correspondence. I finally advocate an interpretation that makes the best sense of his overt comments as well as of his (...) actual scientific practice. Contrary to widely accepted views, I argue that there are no substantial discontinuities in his understanding of his own method, or between his theory and practice. I claim, by contrast, that Descartes advocated a minimal method: a method that says little, but that, nonetheless, marks a revolutionary rupture with the existing forms of explanation. (shrink)

Recent research has defended the surprising thesis that in many cases the search for truth is better off if the information exchanged between the members of an epistemic community is limited. This is what one may call the limited information thesis. There is, however, the possibility of an even more radical position than this: the thesis that any communication between peers has zero epistemic value and that the search for truth is better off if the truth-inquirer does not take into (...) consideration the truth-claims of her peers. This can be called the solitude thesis. The paper defends the claim that Descartes is a supporter of the solitude thesis with respect to metaphysical inquiry. The defense is facilitated by means of interpreting textual evidence found in Descartes’ essays Discourse on the Method, The Search for Truth and the Meditations on First Philosophy. (shrink)

During the 1630s Descartes recognized that he could not expect all legitimate claims in natural science to meet the standard of absolute certainty. The realization resulted from a change in his physics, which itself arose not through methodological reflections, but through developments in his substantive metaphysical doctrines. Descartes discovered the metaphysical foundations of his physics in 1629-30; as a consequence, the style of explanation employed in his physical writings changed. His early methodological conceptions, as preserved in the Rules (...) and sketched in Part Two of the Discourse, pertained primarily to his early work in optics. By the early 1630s, Descartes was concerned with new methodological problems pertaining to the postulation of micro-mechanisms. Recognition of the need to employ a method of hypothesis led him to lower the standard of certainty required of particular explanations in his mature physics. (shrink)

In early 2014, Descartes’ Meditations joined the short but select list of Western Philosophy texts that have an entire Cambridge Companion dedicated to them. (The list includes Hobbes’ Leviathan, Kant’s Critique of Pure Reason, Locke’s Essay, Nozick’s Anarchy, State and Utopia, Darwin’s The Origin of Species, Plato’s Republic, and Spinoza’s Ethics. Hume’s Treatise is also expected to be added to the list before the end of the year.) To set itself apart from the many existing volumes that offer guidance (...) and clarification to the Meditations, this new collection of essays aims to prove that the Meditations is not a repository of considered, fully-articulated and spelled-out Cartesian views but rather the exposition of the process, the sequence of steps for arriving at such views. To that end, the rhetorical aspects of the Meditations are especially emphasized: who is speaking, who is spoken to, the manner in which things are phrased, the setting as well as the intended goal of (the speaker of) the Meditations are carefully scrutinized.

The relation between extension and impenetrability is a major issue in the Descartes-More correspondence, which implies an analysis of the concept of extension. The mereological structure partes extra partes is a crucial element here. Both philosophers hold two opposed views of this mereological structure. I try to show that these two views can be traced back to scholastic discussions on quantity’s relation to extension. This background provides a vantage point, which enables to propose a new construal of the argumentative (...) exchange around impenetrability, and which casts some light too on our understanding of two properties – spissitude and indiscerpibility – which More attributes to spiritual extension in his later writings.

Descartes is notorious for holding a strong anti-vacuist position. On his view, according to the standard reading, empty space not only does not exist in nature, but it is logically impossible. The very notion of a void or vacuum is an incoherent one. Recently Eric Palmer has proposed a revisionist reading of Descartes on empty space, arguing that he is more sanguine about its possibility. Palmer makes use of Descartes’ early correspondence with Marin Mersenne, including his commentary (...) on Galileo’s Two New Sciences. I argue that Palmer’s reading is mistaken, and that it relies on an understandable but faulty inference—i.e., that if Descartes considers the implications of an opposing view, he must find it at least coherent. Descartes, as I show from his correspondence and other texts, uses a variety of persuasive strategies, and levels charges of different logical strength, against positions which he takes to be incoherent. Thus we cannot infer from the fact that Descartes argues, e.g., that something is a superfluous theoretical entity, that he admits that entity’s coherence. He often chooses to argue a weaker thesis against an opponent so that he can use an argument to which the opponent is more likely to agree. (shrink)

I argue that Descartes' Second Causal Proof of God in the Third Meditation evidences, and commits him to, the belief that time is "strongly discontinuous" -- that is, that there is actually a gap between each consecutive moment of time. Much of my article attempts to reconcile this interpretation, the "received view," with Descartes' statements about time, space, and matter in his other writings, including his correspondence with various philosophers.

Despite Kant's belief in a universal causal determinism among phenomena and his rejection of any noumenal agency in brutes, he nevertheless rejected Descartes's hypothesis that brutes are machines. Explaining Kant's response to Descartes forms the basis for this discussion of the nature of consciousness and matter in Kant's system. Kant's numerous remarks on animal psychology-as found in his lecture notes and reflections on metaphysics and anthropology-suggest a theory of consciousness and self-consciousness at odds with that traditionally ascribed to (...) him.

The chapter focuses on attributions of the transparency of thought to early modern figures, most notably Descartes. Many recent philosophers assume that Descartes believed the mind to be “transparent”: since all mental states are conscious, we are therefore aware of them all, and indeed incorrigibly know them all. Descartes, and Berkeley too, do make statements that seem to endorse both aspects of the transparency theses (awareness of all mental states; incorrigibility). However, they also make systematic theoretical statements (...) that directly countenance “unnoticed” thoughts or mental states, that is, thoughts or mental states of which the subject is unaware and has no knowledge. Descartes, having identified the essence of mind with thought or representation, distinguishes bare states of mind from states of which we have reflective awareness, thereby providing a theoretical tool for understanding both his seeming endorsement of transparency and his actual denial of it: Descartes distinguished between a basic perceptual state, or a basic awareness, and reflectively conscious states that involve explicit noticing and cognizing on the part of the subject. Leibniz (as is better known) directly endorsed a similar distinction between bare perception and reflective consciousness, using the term “perception” for the first and “apperception” for the second. In these cases, bare perceptions are not transparently available to the subject, and so in fact the subject does not have knowledge, hence does not have incorrigible knowledge, of all its occurrent mental states. This chapter gives evidence to support these claims; elaborates the complex psychology of the subject found in Descartes and other early moderns; and notes some ways in which these early moderns contributed to the genesis of the modern subject. Finally, it compares McDowell’s conception of the Cartesian mind with the conceptions of mind found in the writings of Descartes, Berkeley, and Leibniz, finding that his characterization caricatures the positions of early modern philosophers. McDowell's characterization has four elements: consciousness as essence of mind; intentionality as exclusively mental; the veil of perception; and the transparency of mind. Only the second point, about intentionality, fully fits Descartes. As a consequence of his own misdirection, McDowell misses the actual basis of his difficulty in connecting mind with world, which arises from a point of agreement between him and Descartes: the removal of intentionality from material sensory systems. But whereas Descartes could relocate (nonconceptual) sensory intentionality in mental states, McDowell is left to account for it with his overly cognitivized scheme of perceptual content as exclusively conceptual.

Tradução para o português do verbete de John Cottingham sobre a metafísica de Descartes, publicado in: "A Companion to Metaphysics", ed. Kim, Sosa e Rosenkranz (Oxford: Wiley-Blackwell, 2009) .

In this paper I develop a new account of the philosophical motivations for Descartes’s theory of judgment. The theory needs explanation because the idea that judgment, or belief, is an operation of the will seems problematic at best, and Descartes does not make clear why he adopted what, at the time, was a novel view. I argue that attending to Descartes’s conception of the will as the active, free faculty of mind reveals that a general concern with (...) responsibility motivates his theory of judgment. My account avoids some unappealing features of the standard interpretation, renders the theory more plausible than many have suggested, and explains why his theory does not fall neatly into any current-day position on the issue of the control we have over belief.

In this chapter, I examine similarities and divergences between Du Châtelet and Descartes on their endorsement of the use of hypotheses in science, using the work of Condillac to locate them in his scheme of systematizers. I conclude that, while Du Châtelet is still clearly a natural philosopher, as opposed to modern scientist, her conception of hypotheses is considerably more modern than is Descartes’, a difference that finds its roots in their divergence on the nature of first principles.

Gregor Schiemann verteidigt die Aktualität des aristotelischen und cartesianischen Naturbegriffes, die Natur in Gegensatz zu Nichtnatürlichem definieren. Als gültig könnnen sich diese traditionellen Naturbegriffe jedoch nur noch innerhalb begrenzter Kontexte erweisen. -/- Im ersten Teil seines Buches zeigt der Autor, dass Aristoteles' Bestimmung der Natur als Gegenbegriff zur Technik in der Lebenswelt sowie Descartes' Dualismus von Natur und Geist für das eigene Bewusstseinserleben orientierungsleitend geblieben sind. Dass die Begriffspaare nicht nur in gesonderten Kontexten vorkommen, sondern sich ihre Anwendungen auch (...) wechselseitig durchdringen, führt er im zweiten Teil am Beispiel von Aristoteles' Seelenlehre und Descartes' Mechanismus aus. Die naturphilosophische und erkenntnistheoretische Untersuchung verbindet Elemente der analytischen Philosophie mit Ansätzen der Phänomenologie. Sie will zu einem pluralen Verständnis der Natur beitragen, das universelle Geltungsansprüche verabschiedet. (shrink)

The popular Cartesian reading of George Berkeley's philosophy of mind mischaracterizes his views on the relations between substance and essence and between an idea and the act of thought in which it figures. I argue that Berkeley rejects Descartes's tripartite taxonomy of distinctions and makes use of a fourth kind of distinction. In addition to illuminating Berkeley's ontology of mind, this fourth distinction allows us to dissolve an important dilemma raised by Kenneth Winkler.

This paper discusses the question why the first edition of Descartes' Meditations carries a title announcing a proof of the immortality of the soul, whereas Descartes himself (in the Synopsis as well as in his Replies) explicitly denies any intention to deliver such a proof. In the first part of the paper, I refute existing attempts to explain this inconsistency. In the second part, I argue that it was Descartes' intention to announce a proof for the immaterialitas, (...) not for the immortalitas of the soul, and that the first of these two words has been misread, probably by the Paris printer, and turned into immortalitas. I first adduce as evidence a remark by Baillet in his second (abbreviated) version of Descartes' biography, a remark that has hitherto gone unnoticed in the learned literature. (Baillet explicitly states, using French words indeed, that immortalitas/immortalité was put instead of immaterialitas/immaterialité.) I secondly point to three statements by Descartes concerning either the Meditations or the content of metaphysics generally; Descartes mentions the immateriality of the soul on all three occasions. -/- .

In Squaring the Circle in Descartes’ Meditations, Stephen Wagner aims to show that Descartes’ project in the Meditations is best understood as a ‘strong validation of reason’ i.e., as proving in a non-circular way that human reason is a reliable, truth-conducive faculty. For such an enterprise to qualify as a ‘strong’ validation, Wagner contends, skeptical doubt must be given its strongest force. The most stringent doubt available in the Meditations is the deceiving God. To rule out the possibility (...) that an omnipotent God created humans so that their best functioning cognitive faculties provide misleading information about what the world is like, Descartes must prove that a non-deceiving God exists. Furthermore, only a non-circular proof will count as a ‘validation.’ Wagner spells out the requirements of non-circularity as involving a proof for God’s existence that is not deductive, does not simply achieve a clear and distinct perception of God’s existence, and proceeds on the basis of perceptions that remain true even when the reasons underlying them are not attended to any longer by the meditator.

In this paper, I explore René Descartes' conception of human freedom. I begin with the key interpretive challenges of Descartes' remarks and then turn to two foundational issues in the secondary literature: the philosophical backdrop of Descartes' remarks and the notions of freedom that commentators have used to characterize Descartes. The remainder of the paper is focused on the main current debate: Descartes' position on the relationship between freedom and determinism.

En este artículo examino dos criterios para la existencia de estados mentales, el de Descartes y el de Turing. Mientras que el primero plantea que las máquinas no pueden pensar en principio, el segundo defiende la inteligencia de máquina. Pese a esto, ambos parecen coincidir en que la decisión sobre la presencia de estados mentales es tomada por alguien que juzga internamente la misma. Si bien ello es esperable del racionalismo cartesiano, en el funcionalismo de Turing es sorprendente. En (...) efecto, ningún comentarista de su Juego de la Imitación repara en el hecho de que los interrogadores son una instancia que no parece reemplazable y, además, que dichos interrogadores aplican un criterio internalista para decidir si están frente a una mente o un computador. Tal aproximación internalista a la mente, argumento, representa una dificultad para que una máquina pase el Test de Turing. Por este motivo concluyo que dicho test no solo no reemplaza la pregunta ¿pueden pensar las máquinas?; adicionalmente traslada de modo dramático el foco del debate a la filosofía de la mente.

Descartes claimed that he thought he could deduce the assumptions of his Meteorology by the contents of the Discourse. He actually began the Meteorology with assumptions. The content of the Discourse, moreover, does not indicate how he deduced the assumptions of the Meteorology. We seem to be left in a precarious position. We can examine the text as it was published, independent of Descartes’ claims, which suggests that he incorporated a presumptive or hypothetical method. On the other hand, (...) we can take Descartes’ claims as our guide and search for the epistemic foundations of the Meteorology independent of the Discourse. In this paper, I will pursue the latter route. My aim is to explain why, and how, Descartes thought that he had deduced the assumptions of the Meteorology. My interest, in this case, is solely Descartes’ physical foundation for the Meteorology, in the physics and physiology that resulted in Descartes’ explanation. With this aim, I provide an interpretation of Descartes’ World where many of its conclusions serve as evidence for the assumptions of the Meteorology. I provisionally conclude that Descartes thought that his World was the epistemic foundation for his Meteorology. (shrink)
