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.

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 the Dedicatory Letter of the Meditations, René Descartes claims that he will offer a proof of the soul’s immortality, to be accomplished by reason alone. This proof is also promised by the title page of the first edition of the Meditations, which includes the words “in which the existence of God and the immortality of the soul are demonstrated.” But in the Synopsis, and later in his replies to objections, Descartes gives a more nuanced account of the (...) possibility of proving immortality and whether an attempt is even to be found in the Meditations. To confuse matters further, the title page of the second edition no longer mentions a demonstration of immortality but promises only to prove the distinction between body and soul. The question arises, therefore, whether the Meditations contains a purely philosophical demonstration of the immortality of the soul. (shrink)

Descartes is not well known for his contributions to ethics. Some have charged that it is a weakness of his philosophy that it focuses exclusively on metaphysics and epistemology to the exclusion of moral and political philosophy. Such criticisms rest on a misunderstanding of the broader framework of Descartes’ philosophy. Evidence of Descartes’ concern for the practical import of philosophy can be traced to his earliest writings. In agreement of wisdom that is sufficient for happiness. The Third (...) part of his Discourse on the Method presents what he calls a provisional morality, a morality to govern our behaviour while we are in the process of revising our beliefs and coming to certainty. In the tree of philosophy, in the Preface to the French translation of the Principles of Philosophy, morals are listed as one of the fruits of the tree, along with medicine and mechanics. It is also a theme in the letters he exchanged with the Princess Elisabeth of Bohemia in the mid-1640s, together with another concern the passions, what they are, and more importantly, how to control them. These themes are intertwined again in Descartes last major work, The Passions of the Soul (1649). Descartes did not write extensively on ethics, and this has led some to assume that the topic lacks a place within his philosophy. It is an attempt to outline Descartes’ ethical ideas mainly in Discourse on the Method. (shrink)

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)

I offer a novel reading in this dissertation of René Descartes’s (1596–1650) skepticism in his work Meditations on First Philosophy (1641–1642). I specifically aim to answer the following problem: How is Descartes’s skepticism to be read in accordance with the rest of his philosophy? This problem can be divided into two more general questions in Descartes scholarship: How is skepticism utilized in the Meditations, and what are its intentions and relation to the preceding philosophical tradition? -/- I (...) approach the topic from both a historical and a text-based analysis, combining textual and contextual research. I examine Descartes’s skepticism against two main traditions in the historical analysis: philosophical skepticism and Aristotelian Scholasticism. I argue that skepticism in the Meditations is intended to oppose and upheave both Scholasticism and skepticism. The intended results of the work are not merely epistemological but also metaphysical and even ethical. Furthermore, these ambitions cannot be neatly distinguished but merge into each other. -/- The third historical context against which the skeptical meditations are examined is the literary genre of meditative exercises, particularly from the 1500–1600’s, which, while religiously and spiritually oriented, likewise provided the practitioner with an enlightened understanding of self-knowledge and their cognitive place in the world on the way to closer spiritual proximity to God. I argue by this reading that the skepticism of the Meditations is an attentive, meditational cognitive exercise that is not merely instrumental and methodological but is to have a genuine and serious (psychologically real) effect on our thinking. The skeptical meditation is not simply a theoretical thought experiment but is to be seriously practiced as a transformative process of reorienting one’s cognitive framework to discover truth, certainty, and a way to a happy, tranquil, and virtuous life. -/- I offer a close reading in the textual analysis of the first three meditations of the Meditations. I argue that the meditative skepticism employed in the work does not reject the previous beliefs but suspends judgment on them, withdrawing assent until further evidence can be found. I introduce a new term into Descartes scholarship in this analysis, based on the terminology of ancient skepticism: Cartesian epochē (gr. epochē, suspension, withdrawal). Instead of rejecting previous beliefs or assenting to the probably false, the skeptical procedure of the Meditations is argued to emulate in important ways the suspension of judgment on equally balanced reasons in ancient Pyrrhonian skepticism. Novel interpretations are presented along the way of the will’s freedom, of the First Meditation’s skeptical scenarios, of the cogito, and of the vindication of metaphysical certainty, as well as a clarification of the Cartesian Circle problem. -/- Reinterpreting the relation of Descartes’s skepticism to the preceding historical and literary traditions leads to a new look at the skeptical method itself. Presenting a new interpretation of skepticism in the Meditations leads at the same time to a new look at its relation to the historical context. The two research questions are, then, intrinsically tied together. -/- My focus in the study is on the Meditations, but I also reference and discuss Descartes’s other philosophical works, as well as his correspondence, when necessary.

Descartes’s meditator thinks that if she does not know the existence of God, she cannot be fully certain of anything. This statement seems to contradict the cogito, according to which the existence of I is indubitable and therefore certain. Cannot an atheist be certain that he exists? Atheistic knowledge has been discussed almost exclusively in relation to mathematics, and the more interesting question of the atheist’s certainty of his existence has not received the attention it deserves. By examining (...) the question of atheistic knowledge in relation to the cogito, I articulate the advantage Descartes sees in having knowledge of God. I challenge a long-held reading of the cogito where “I exist” is the first full certainty and argue that while atheistic cogito is more certain than atheistic knowledge in mathematics, it cannot be a starting point for lasting and stable science, because science requires knowing the existence of the non-deceiving God.

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.

This paper investigates the historical origin and ancestors of typicality, which is now a central concept in Boltzmannian Statistical Mechanics and Bohmian Mechanics. Although Ludwig Boltzmann did not use the word typicality, its main idea, namely, that something happens almost always or is valid for almost all cases, plays a crucial role for his explanation of how thermodynamic systems approach equilibrium. At the beginning of the 20th century, the focus on almost always or almost everywhere was fruitful for developing measure (...) theory and probability theory. It was apparently Hugh Everett III who first mentioned typicality in physics in 1957 while searching for a justification of the Born rule in his interpretation of quantum mechanics. The historically closest concept before these developments is moral certainty, which was invented by the medieval French theologian Jean Gerson, and it became a standard concept at least until the Age of Enlightenment, when Jakob Bernoulli proved the Law of Large numbers.

Descartes holds that the tell-tale sign of a solid proof is that its entailments appear clearly and distinctly. Yet, since there is a limit to what a subject can consciously fathom at any given moment, a mnemonic shortcoming threatens to render complex geometrical reasoning impossible. Thus, what enables us to recall earlier proofs, according to Descartes, is God’s benevolence: He is too good to pull a deceptive switch on us. Accordingly, Descartes concludes that geometry and belief in (...) God must go hand in hand. However, I argue that, while theism adds a layer of psychological reassurance, the mind-independent reality of God would ensure the preservation of past demonstrations for atheists as well. (shrink)

This paper focuses on Foucault's concept of the Panopticon. The Panopticon since time immemorial has been used as a concept in order to control society. Since this is being used as a tool to control society, this then is considered to be a form of technology of which is being used by individuals who hold power.

This is an excerpt of Aquinas' proof of the existence of God. In proving God's existence, Aquinas lays out a cosmological argument of which also sets that tone for his seminal work in epistemology.

In the Principles of Philosophy, Descartes explains several observable phenomena showing that they are caused by special arrangements of unobservable microparticles. Despite these microparticles being unobservable, many passages suggest that he was very confident that these explanations were correct. In other passages, however, Descartes points out that these explanations merely hold the status of “suppositions” or “conjectures” that could be wrong. My main goal in this chapter is to clarify this apparent conflict. I argue first that for (...) class='Hi'>Descartes it was indeed possible to have knowledge of unobservable particles and structures, and that the possibility of natural explanations being wrong should be understood as these explanations not being absolutely certain, but only morally certain. I use the debate in contemporary philosophy of science between scientific realism and antirealism as a framework to understand how Cartesian explanations work. Especifically, I argue that Cartesian explanations rely on what Ernan McMullin calls retroduction, which is a mode of inference that justifies beliefs in concrete unobservable entities and processes, based on considerations such as simplicity, coherence, etc. This kind of justification is of common use among scientific realists. Thus, another goal of this chapter is to highlight the relevance of Descartes’ ideas about explanation in the contemporary debate on scientific realism. (shrink)

This book attempts to contribute a historical and interpretive study of Descartes' epistemology. It provides a systematic and exhaustive clarification of the mysterious and puzzling doctrine of "clear and distinct perception" and illuminates the relationships between this doctrine and four other central notions: "truth," "metaphysical doubt," "(metaphysical) certainty," and "knowledge." -/- Roughly speaking, a clear and distinct perception is a pure understanding, an intellectual perception, or a mental intuition in which a purified and attending mind has a simple (...) mental intuition of a simple proposition or a necessary deduction (i.e., a complex mental intuition) from such simple propositions to a complex proposition. A simple proposition can be regarded as a necessary conjunction of simple ideas. Descartes' composition theory of ideas, which supposes that all ideas are composed of simple ideas, provides a crucial basis for clear and distinct perception. -/- Descartes' doctrine of clear and distinct perception is an attempt at mathematizing epistemology and is the main content of his new "method" (for truth and knowledge), which he sought throughout his life. -/- This book attempts to shape a new image of Descartes' epistemology.

Enlightenment philosopher, René Descartes, set out to establish what could be known with certainty, untainted by a deceiving demon. With his method of doubt, he rejected all previous beliefs, allowing only those that survived rigorous scrutiny.

He subjects Descartes's conclusions to Descartes's own uncompromising methodology to determine whether Descartes escaped from a (...) self-imposed radical skepticism. (shrink)

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

There is a broad distinction in Descartes’s writings between doctrine and method. The staying power of these two elements has been unequal. Descartes’s doctrinal influence on contemporary epistemology has been largely as a foil against which some of its major currents have been developed. Few contemporary philosophers have adopted his positive doctrines. The situation is brighter on the methodological side. Here, Descartes’s practice of beginning with common sense and moving, step by step, to philosophical conclusions is a (...) model much admired by contemporary philosophers. Still, the negative verdict on doctrine stands as the main verdict. I maintain that this verdict is undeserved I first distinguish between Descartes’s general epistemology and the purpose to which he puts it – the quest for certainty. I then argue for a positive verdict for his general epistemology. I do so by showing that Descartes has a non-normative account of knowledge but an “ethics of responsible belief ” account of epistemic normativity. Unlike some contemporary accounts of epistemic responsibilism, e.g. Bonjour, in which epistemic responsibility is a condition for knowledge, on Descartes’s account, knowledge is a condition for epistemic responsibility. Descartes thus anticipates what Sylvan calls the “knowledge-first” approach in contemporary epistemology, which I defend in the paper. Relying on Audi’s distinction between “sources” and “reasons,” I show that Descartes’ analysis of knowledge proper, which I also defend in the paper, anticipates and improves on the “factive access” analysis of knowledge due to McDowell.

In the second Meditation, Descartes argues that, because he thinks, he must exist. What are his reasons for accepting the premise of this argument, namely that he thinks? Some commentators suggest that Descartes has a ‘logic’ argument for his premise: It is impossible to be deceived in thinking that one thinks, because being deceived is a species of thinking. In this paper, I argue that this ‘logic’ argument cannot contribute to the first certainty that supposedly stops the (...) Cartesian doubt. Rather, this certainty must be based on another type of access to our own minds, possibly a faculty of introspection. Applying this result to contemporary constitutive theories of self-knowledge (Wright), I show that these cannot be part of what justifies the ascription of particular mental states to a subject. -/- En la segunda de sus "Meditaciones metafísicas", Descartes argumenta que, porque piensa, debe existir. ¿Cuáles son sus razones para aceptar la premisa de este argumento, a saber el que piensa? Algunos comentaristas sugieren que Descartes tiene un argumento 'lógico' para su premisa: No es posible ser engañado en creer que uno piensa, porque el ser engañado también es una especie de pensamiento. En mi ponencia arguyo que este argumento 'lógico' no puede contribuir a la certeza que supuestamente para la duda cartesiana. Más bien, esta certeza debe fundarse en otro tipo de acceso, talvez de forma introspectiva, que tenemos a nuestra propia mente. Aplicando este resultado a teorías contemporáneas constitutivas del autoconocimiento (Wright), muestro que éstas no pueden contribuir a la justificación de la adscripción de estados mentales particulares.

The phenomenon of knowledge is a fundamental issue in epistemology as a main branch of philosophy concerned with knowledge related problems. Over time, epistemologists attempted to give us or provide clues as to what reality actually is, that is the question of the certainty of knowledge has always been topical in any epistemic enterprise. The search for knowledge becomes more cumbersome when one considers the challenge of the skeptics and sophists about the ability of man knowing anything for certain. (...) To some philosophers, the emergence of the skeptics’ challenge is seen as an attempt to bring this noble enterprise into a quagmire. However, the introduction of Descartes foundationalism opens a new chapter and a serious challenge to the skeptics' position on the certainty of knowledge. Consequently, many have asked the question: is Descartes foundationalism merely an answer to the skeptic's challenge or a way forward for epistemology? This paper examines this question with a view to asserting a position regarding the issue, which is that it is both a response and a way forward for epistemology. (shrink)

Some people insist that they are dead. Rather than starting with the usual assumption that delusions are ‘false beliefs about external reality’ I want to consider how interpreting their claim as a report of a certain kind of anomalous experience assists us in understanding why they are certain, why their claim is immune from evidence to the contrary, and why they do not act in ways we would expect were they to believe their claim to be true of the world. (...) While this helps us understand cases where people do not act on their delusions, more must be said about the people who do act on their delusions. I shall attempt to describe a process where an intense anomalous experience leads to a context-specific narrowing of attention. The ultimate result of this is that the appearance / reality distinction becomes lost in the context of the anomalous experience. The sense of conviction that would be appropriately associated with a report of experience thus becomes inappropriately associated with a claim about external reality. While there have been efforts to provide cognitive therapy for delusional subjects such therapy seems to be based on the notion that confronting them with their contradictions will assist in weakening their sense of certainty about the delusional utterance. I consider whether more progress could be made via empathetic validation of the sense of certainty which is appropriate when associated with the person’s anomalous experience. (shrink)

When is it permissible to rely on a proposition in practical reasoning? Standard answers to this question face serious challenges. This paper uses these challenges to motivate a certainty norm of practical reasoning. This norm holds that one is permitted to rely on p in practical reasoning if and only if p is epistemically certain. After developing and defending this norm, I consider its broader implications. Taking a certainty norm seriously calls into question traditional assumptions about the importance (...) of belief and knowledge. In particular, it raises the possibility that many epistemological jobs that are usually assigned to belief and knowledge should be reallocated to two related but importantly different states: psychological and epistemic certainty.

By pushing Descartes to more clearly explain the union of body and soul beyond the functioning of a ‘strong’ passion, namely sadness, Elisabeth wants Descartes to review his idea of the passions, and his understanding of the ‘theory of the four humors’. This chapter aims at showing that Descartes turns away from Galen’s theory of the humors, which he globally adopts in the 1633 Treatise of Man. With the shift in his conceptualization of the humors between this (...) Treatise and the Treatise of the Passions (1649), Descartes analyzed more specifically the inner feelings, consciousness, and the passions, by considering that a man is not simply a body, but a psychophysical being, with a body and a soul.

**For my more recent views of the third kind of cognition, see my "Finding Oneself in God"** -/- Abstract: Cognition of the third kind, or scientia intuitiva, is supposed to secure beatitudo, or virtue itself (E5p42). But what is scientia intuitiva, and how is it different from (and superior to) reason? I suggest a new answer to this old and vexing question at the core of Spinoza’s project in the Ethics. On my view, Spinoza’s scientia intuitiva resembles Descartes’s scientia (...) more than has been appreciated. Although Spinoza’s God is not Descartes’s benevolent, transcendent God, Spinoza agrees with Descartes that the highest certainty requires that a cognizer correctly conceive of God and her causal relation to God; it is only with cognition of the third kind that a cognizer can be certain that her adequate (that is, clear and distinct) representations of extramental things agree with formally real, extramental ideata, and so are true. If this is right, a reading of Spinoza that has dominated scholarship since the Ethics’ publication is misguided: for Spinoza, it is not always the case that having (and recognizing that one has) a clear and distinct idea is sufficient for knowing that that idea is true. I end the chapter by suggesting why scientia is intuitive for Spinoza: Spinoza attempts to avoid Cartesian-Circle-style circularity by insisting that a cognizer must intuit the correct representation of God and God’s relation to things.

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.

The distinction between the mental operations of abstraction and exclusion is recognized as playing an important role in many of Descartes’ metaphysical arguments, at least after 1640. In this paper I first show that Descartes describes the distinction between abstraction and exclusion in the early Rules for the Direction of the Mind, in substantially the same way he does in the 1640s. Second, I show that Descartes makes the test for exclusion a major component of the method (...) proposed in the Rules. Third, I argue that in Rule 14 the exclusion-abstraction distinction is connected to a theory of distinctions, which includes a notion of real distinction as essentially tied to the imagination. This sheds light on Descartes’ development in and after the Rules. (shrink)

Descartes and Boyle were the most influential proponents of strict mechanist accounts of the physical world, accounts which carried with them a distinction between primary and secondary (or sensible) qualities. For both, the distinction is a piece of natural philosophy. Nevertheless the distinction is quite differently articulated, and, especially, differently grounded in the two thinkers. For Descartes, reasoned reflection reveals to us that bodies must consist in mere extension and its modifications, and that sensible qualities as we conceive (...) of them based on sense perception can pertain only to the mind. Just how we are supposed to arrive at this realization is, this essay will argue, a deep puzzle that brings us to the basic assumptions of Descartes' metaphysics. For Boyle, by contrast, while reflection can reveal the unique explanatory status of mechanism, and, thus, the primary/secondary quality distinction, only experience can confirm its truth. Our central focus will be on Descartes, and on the question: How does he intend to remove the sensible qualities from the physical world, how does he strip them from bodies? I will try to show that Descartes has an argument that he takes to show a priori that sensible qualities cannot be attributed to the material world (as foundational qualities, or, as we conceive of them based on sense experience). The argument fails, however, leaving him with at best a partly empirical case for removing the sensible qualities, based on the purported explanatory success of his physics. (shrink)

This chapter explores some key issues within Descartes’s theory of cognition. The starting-point is a recent interpretation, according to which Descartes is part of a tradition of theorizing about human cognition, beginning from the idea that we are in principle capable of articulating or grasping the basic order of reality. Earlier readings often take Descartes to question whether we have any cognitive access to reality at all. On the new reading, Descartes instead defends a robust conception (...) of our cognitive relation to reality—our cognition needs to be “determined by reality,” as John Carriero puts it. One important element of Carriero’s interpretation is that Descartes’s notion of idea is to be understood along the lines of the Aristotelian doctrine of formal identity between cognizer and cognized. Here it is argued that retaining the latter doctrine faces some difficulties, given the novel conception of the structure of reality defended by Descartes. This chapter proposes that he needs an alternative account of what it is for a cognizer to be determined by reality. Attending to some important differences between the innate idea of extension and that of God, the chapter concludes that Descartes may not have a fully worked-out account of his own. Considering some of the problems inherent in his views can, however, shed light on the, from our contemporary perspective, peculiar role both Spinoza and Leibniz give to God in accounting for cognition.

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Philosophy 43.1 (2005) 55-81 [Access article in PDF] Self-Knowledge in Descartes and Malebranche Lawrence Nolan John Whipple 1. Introduction Descartes's notorious claim that mind is better known than body has been the target of repeated criticisms, but none appears more challenging than that of his intellectual heir Nicolas Malebranche.1 Whereas other critics—especially twentieth-century philosophers eager to use Descartes as their whipping (...) boy—have often been uncharitable, Malebranche accepts many of the fundamental Cartesian doctrines, including mind-body dualism. But he argues that Descartes's position on knowledge of the mind is internally inconsistent. Malebranche agrees with Descartes that the existence of the mind is better known than that of body, but he vehemently denies that the nature of the mind is better known. This denial is based on his view that we lack a clear idea of the mind.2 [End Page 55]Malebranche's polemic has attracted much attention in recent scholarship.3 The growing consensus among commentators is that Malebranche develops a devastating internal critique of Descartes's theory of the mind. For example, Nicholas Jolley writes: "In his case for his negative thesis [concerning knowledge of the mind] Malebranche mounted a powerful, even annihilating, critique of Descartes. This critique embodies the remarkable insight that there is a serious muddle at the heart of Descartes's whole theory of knowledge."4 In a book-length defense of Malebranche's critique, Tad Schmaltz also emphasizes its internal character: "the interpretation here of Malebranche's theory presents it as fundamentally Cartesian, and thereby serves to reinforce his own view that he has provided an authoritative interpretation of the account of mind in the writings of Descartes and other Cartesians."5 Schmaltz also asserts: "Malebranche took his negative thesis concerning our knowledge of the soul to involve not so much a rejection of Cartesianism as an internal correction of it."6We think such remarks misstate the case. Indeed, we argue in this paper that Malebranche's polemic fails as an internal critique of Descartes's theory of the mind. Although we do not here aspire to defend Descartes's strong thesis—that mind is better known than body—we do think he can consistently maintain that we have a clear and distinct idea of the mind, and thus that our knowledge of the mind's nature is at least on a par with our knowledge of corporeal nature.7 While Malebranche's rhetoric would encourage us to think that the debate between him and his predecessor is being fought on common or neutral ground, the fact is that Malebranche often appeals to assumptions and aspects of his own theory of "Vision in God" that Descartes would reject. Once more, he interprets Descartes's theory of knowledge in ways that are misguided and sometimes even uncharitable. If Malebranche's critique succeeds at all, it succeeds only against a straw man—Malebranche's Descartes and not the historical figure.Ours is not the first effort to defend Descartes against this particular attack. When Malebranche first published his critique in Book Three of his first great work, The Search After Truth (1674),8 Descartes had been dead for over two decades, [End Page 56] but he was ably defended by the famous Cartesian Antoine Arnauld in On True and False Ideas (1683). In the ensuing debate Arnauld was clearly the superior dialectician, but while winning several tactical points, he appears not to fully appreciate the crux of Malebranche's argument, or at least that is the view of Jolley and Schmaltz.9 We have a somewhat higher opinion of Arnauld's side of the debate. Granted, some of his defenses are facile and can be easily dismissed; others however are quite compelling when properly developed. In at least one instance, we attempt to provide that development. At the same time we think it is a mistake to treat Arnauld as Descartes's surrogate or as if he had issued the final salvo from the camp of the orthodox Cartesians. Arnauld was a... (shrink)

The influential physicist Richard Feynman became interested in the relationship between religion and science during a mid-career phase. He proposed that their interface was embroiled in unresolvable difficulties. He felt that science demanded an attitude of uncertainty for its claims, while religion contrarily required certain belief in its core doctrines. Though possessing several non-contradictory dimensions, Feynman felt that the nature of the truth claims of science and religion suffered from insurmountable elemental conflicts. This was by contrast to Karl Popper, the (...) leading critical rationalist of the 20th century, who argued that there could be no tension between science and religion. This paper will argue that the ‘Feynman Problem’ is not as insoluble as it appears. Rather, several solutions exist within critical rationalism. Two will be presented-the first revolves around the conjectural basis of knowledge and is already a well characterised critical rationalist notion. The second is a novel solution based on the separate categorisation of psychological, pragmatic, and epistemological attitudes to religion and science. Karl Popper’s view of religion-science dissimilarity was a minimalist point of departure for critical rationalists, who have developed increasingly sophisticated frameworks for investigating the relationship between faith and reason. Critical rationalism represents an equally inspirational methodology for the pursuit of scientific and religious truth. Though both Feynman and Popper’s views on religion were underdeveloped, they foreshadowed the religion-science frameworks advocated by many late 20th century scientists, especially in the form of New Atheism and Gould’s NOMA theory.

(Shoshana Smith now goes by her married name, Shoshana Brassfield: http://philpapers.org/profile/37640) Descartes famously claims that everything we perceive clearly and distinctly is true. Although this rule is fundamental to Descartes’s theory of knowledge, readers from Gassendi and Leibniz onward have complained that unless Descartes can say explicitly what clear and distinct perception is, how we know when we have it, and why it cannot be wrong, then the rule is empty. I offer a detailed analysis of clear (...) and distinct perception, showing how Descartes answers these questions. Many doubts about the usefulness of the clarity and distinctness rule arise from the mistaken assumption that in clear and distinct perception, like sense perception, we must be able to establish a correspondence between perception and reality before we can have knowledge. I show that Descartes has a different metaphysical picture of clear and distinct perception. Clear and distinct perception is direct perception, typically of essences. On this view, by relying on the intellect instead of the senses, we can have direct perception not only of our own ideas, but also of a mind-independent reality. Because clear and distinct perception is direct perception, problems of correspondence do not arise. My account of clear and distinct perception also yields unique insight into other issues in Descartes, such as the Cartesian Circle and the doctrine of the free creation of the eternal truths.

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).

Descartes’s mechanistic account of the passions is sometimes dismissed as one which lacks the resources toadequately explain the cognitive aspect of emotion. By some, he is taken to be “feeling theorist”, reducing thepassions to a mere awareness of the physiological state of the soul-body union. If this reading of Descartes’spassions is correct, his theory fails not only because it cannot account for the intentional nature of the passions,but also because the passions cannot play the role in Descartes’s (...) moral theory they are meant to play. I arguethat Descartes’s account is not best read as a feeling theory. I defend a reading of the Cartesian passions whichacknowledges their mechanistic nature, arguing that for Descartes, passions are modes of the soul withcognitive significance, they are perceptions of relational axiological properties. Thus, Descartes’s theory of thepassions has the resources to connect it with an account of good conduct. As a means of elaborating on thenormative nature of the passions I consider the role of generosity in Descartes’s moral theory. (shrink)

Presented at the 2010 Annual Meeting of the Association for Core Texts and Courses, New Brunswick, New Jersey, USA, April 2010. -/- René Descartes’ Discourse on Method is paradoxical in several respects: it was published anonymously, yet is rich in autobiographical detail; further, Descartes insists that “the power of judging well and of distinguishing the true from the false…is naturally equal in all men,” and also that “the world consists almost exclusively of … minds for whom [his method (...) of reasoning] is not at all suitable” (1, 9). The Discourse indicates both that the identity of a particular reasoning subject (such as the author of the text itself) does not matter—because all rational beings could come to the same conclusion if using their reason correctly—and yet also that who one is does indeed matter to showing that one counts as one of the select group of subjects who possess knowledge. The method and its results do not speak for themselves; rather, the author must speak for them, and legitimize his authority in the process. If it were the case that Descartes’ plan did not go beyond “trying to reform [his] own thoughts and building upon a foundation which is completely [his] own” (9), then he might rest content with his own convictions regarding the truth of his conclusions, but if he wants to be recognized by others as possessing knowledge then he must either appeal to existing standards of authority to legitimize his method and its conclusions, or argue for the validity of new ones. Either way, the Discourse demonstrates Michel Foucault’s claims that knowledge production is bound up in a social context that determines what counts as true knowledge and who has the authority to speak about it. Descartes’s text shows an author both boldly presenting revolutionary arguments and methods and revealing his awareness of the difficulties and dangers of resisting the accepted standards of knowledge. It can be used to spark discussion amongst students about whether, even if we believe anyone’s reason might produce knowledge, it is still the case today that only some count as “knowers” according to criteria that are socially determined (e.g., institutional affiliation, status within an institution, the acceptability of certain sorts of projects and methods as legitimate for knowledge).

In the practical philosophy of the Discours de la Méthode, before the theoretical metaphysics of Part Four and the Meditationes, Descartes gives us an inductive argument that his method, the procedure and cognitive psychology, is veracious at its inception. His evidence, akin to his Scholastic predecessors, is God, a maximally perfect being, established an ontological foundation for knowledge such that reason and nature are isomorphic. Further, the method, he tells us, is a functional definition of human reason; that is, (...) like other rationalists during this period, he holds the structure of reason maps onto the world. The evidence for this thesis is given in what I call the groundwork to Descartes’ philosophical system, essentially the first half of the Discours, where, through a series of examples in the preamble of Part Two, he, step-by-step, ascends from the perfection of artifacts through the imposition of reason to the perfection of a constituent’s use of her cognitive faculties, to God perfecting and ordering reality. Finally, he descends, establishing the structure of human reason, which undergirds and entails the procedure of the method. (shrink)

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.

Descartes affords several notions of consciousness as he explains the characteristics of the diverse features of human thought from infancy to adulthood and from dreaming to attentive wakefulness. The paper argues that Descartes has a rich and coherent view of conscious mentality from rudimentary consciousness through reflexive consciousness to consciousness achieved by deliberate, attentive reflection.

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)

Abstract -/- Before Descartes, middle age philosophers like Thomas Aquinas (1225-1274), Duns Scotus (1266-1308), and Francisco Suarez (1548-1617) used to discuss the distinction between essence and existence in three ways (of course, Ibn-Sina was the first who made this distinction to rehabilitate Aristotelian philosophy in the Islamic heritage). Descartes was aware of that, but discussed it according to the relation between mind and body. Yet, he told us many times that he was used to separate essence from existence (...) in metaphysical issues. The objective of this paper is first to rephrase his untold opinion about the relation between essence and existence on the basis of his conception of the problem of distinction according to mind and body, and second, to disclose that Descartes's conception of existence is twofold. At the end, it is claimed that his twofold notion of existence and his inability to overcome it, is the principal factor in his failure to explicate everything according to first principles, and so in his failure to defeat skepticism.

In the Principles of Philosophy, Descartes attempts to explicate the well-known phenomena of varying bodily size through an appeal to the concept of "solidity," a notion that roughly corresponds to our present-day concept of density. Descartes' interest in these issues can be partially traced to the need to define clearly the role of matter in his natural laws, a problem particularly acute for the application of his conservation principle. Specifically, since Descartes insists that a body's "quantity of (...) motion," defined as the product of its "size" and speed, is conserved in all material interactions, it is imperative that he explain how solidity influences the magnitude of this force. As a means of resolving this problem, Descartes postulated an idealized condition of "perfect solidity" which correlates a body's "agitation" force (a forerunner of Newton's concept of non-accelerating, or "inertial" motion) with the interplay of its volume, surface area, and composition of minute particles. This essay explores this often misunderstood aspect of Descartes' physics, as well as the special function of idealized conditions in his collision rules. Contrary to those commentators who regard "perfect solidity" as a stipulation on bodily impact, this notion, it will be argued, is primarily concerned with the internal composition of macroscopic bodies, and only indirectly with their collision characteristics. Along the way, many of Descartes' hypotheses will be shown to display a level of sophistication and intricacy that, despite their essential incompatibility, belie several of the common misconceptions of Cartesian science.

In this article, I explore the relationship between desire and emotion in Descartes, Zhu Xi, and Wang Yangming with the aim of demonstrating 1) that Zhu Xi, by keying on the detriments of selfishness, represents an improvement over the more sweeping Cartesian suggestion to control desires in general; and 2) that Wang Yangming, in turn, represents an improvement over Zhu Xi by providing a more sophisticated hermeneutic of the cosmology of desire.

Although Descartes and Malebranche argue that we are immaterial thinking things, they also maintain that each of us stands in a unique experiential relation to a single human body, such that we feel as though this body belongs to us and is part of ourselves. This paper examines Descartes’s and Malebranche’s accounts of this feeling. They hold that our experience of being embodied is grounded in affective bodily sensations that feel good or bad: namely, sensations of pleasure and (...) pain, hunger and thirst, and so on. These bodily sensations ground our experiential identification with the body because they represent the body’s needs and interests as though they were own, such that we experience an important aspect of our well-being as consisting in the preservation of the body. According to these Cartesians, then, we feel embodied in part because we experience ourselves as having a bodily good. (shrink)

I begin this paper with a survey of the textual evidence for a new Cartesian subject, a post-Cartesian Cartesian individual, for whom the life of the body, its passions, and its relationships are central. In the second section, I consider his remarks on hatred, which complicate his view embodied life. Even if Descartes’s study of the passions in his treatise as well as his correspondence calls for a more nuanced understanding of the Cartesian person, we will find in his (...) attention to embodiment a conflicted and wary human being for whom relationships can be nourishing and sweet just as easily as they can be noxious and bitter.

Problem of the existence of God and His relation to the world and human being is seen as one of quite old and main problems of philosophy. Though the existence of God and His essence as a knowledge subject is related to a transcendent being over this universe, human being can find rules made by Him in physical world in which stands. The concept of God constitutes one of the most involved points of Descartes’ philosophy. In fact, for (...) class='Hi'>Descartes, who built his philosophy on physical bases or mechanical world, to place God as condition to his metaphysics originates from the conception that if God does not exist a being does not. In this paper, we will try to explain the relation of God and human and the world in Descartes’ philosophy. (shrink)

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)

The main topic of this paper is the mind-body problem. The author analyzes it in the context of Hus- serlian phenomenology. The key texts for the analysis and interpretation are Descartes’ magnum opus “Meditations on the First Philosophy” and Husserl’ last work “The Crisis of European Sciences and Transcendental Phenomenology”. The author claims that already in Descartes’ text instead of one mind-body problem, one can find two: the ontological mind-body problem (mind-brain relation) and conceptual one (“mind” and “body” (...) as concepts). In Descartes’ “Meditations”, the ontological level is explicit, while the conceptual level is implicit. In Husserl’s “Crisis”, on the other hand, the situation is different: the conceptual level of the problem (as the opposition between transcendental phenom- enology and natural sciences) is explicit, while the ontological level is implicit. Nevertheless, it seems that Husserl has answers to both the “traditional” as well as the “conceptual” mind-body problems. (shrink)
