How does Descartes characterize the peculiar way in which each of us is aware of our bodies? I argue that Descartes recognizes a sense of bodily ownership, such that the body sensorily appears to be one's own in bodily awareness. This sensory appearance of ownership is ubiquitous, for Descartes, in that bodily awareness always confers a sense of ownership. This appearance is confused, in so far as bodily awareness simultaneously represents the subject as identical to, partially composed by, and united (...) to her body, without distinguishing these relations. Finally, the appearance of ownership is grounded in multiple other ways in which the body sensorily appears: namely, in the fact that the body appears to be inescapable, modified by bodily sensations, and an object of special concern.

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)

Children and individuals with developmental disabilities compared to typical participants are disadvantaged not only by virtue of being vulnerable to risks inherent in research participation but also by the higher likelihood of exclusion from research altogether. Current regulatory and ethical guidelines although necessary for their protection do not sufficiently ensure fair distributive justice. Yet, in view of disproportionately higher burdens of co-occurring physical and mental disorders in individuals with DD, they are better positioned to benefit from research by equitable participation. (...) Greater elucidation of this ethical dilemma is called for by researchers, institutional review boards, and funding agencies to urgently redress the imbalance. This article discusses many of the regulatory principles to ensure better research participation of children and individuals with DD: human rights, validity, distributive justice, beneficence/nonmaleficence, and autonomy.

In this essay I argue that one of the things that matters most to Descartes' account of mind is that we use our minds actively. This is because for him only an active mind is able to re-organize its passionate experiences in such a way that a genuinely human, self-governed life of virtue and true contentment becomes possible. To bring out this connection, I will read the Meditations against the backdrop of Descartes' correspondence with Elisabeth. This will reveal that in (...) Descartes' writings there is a crucial connection between the conception of ourselves as dreamers and the idea that we fail to realize our true potential as self-determined, active agents. Dreams, as Descartes conceives them, are passively received mental states that inhibit our freedom to use reason at will. To awaken here takes the form of activating our thoughts, which holds the key to freeing ourselves from the stimulus-response patterns that Descartes takes to be at work in animal conduct. Applied to the Meditations, these insights suggest that this work engages in questions far beyond the epistemological agenda. By activating the mind, the Meditations teach us how to realize our true human potential as virtuous thinkers and passionate agents. (shrink)

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

ABSTRACT In section XII of the First Inquiry, Hume refers to the two Hellenistic schools of skepticism to present his own view of skepticism, which, however, depends on the ancient skeptics mainly indirectly. Hume's view of skepticism depends crucially on Descartes and post-Cartesian philosophers such as Pascal, Huet, Foucher and Bayle, who reacted skeptically to major Cartesian doctrines but followed one version or other of Descartes's methodical doubt. Although all these post-Cartesian philosophers are relevant in section XII, I focus on (...) the topics in which Descartes himself-besides his skeptical followers-seems directly relevant. After an introductory section on Julia Annas' and Richard Popkin's views of Hume's relation to, respectively, ancient and modern skepticism, I turn to section XII and examine what Hume calls "consequent skepticism about the senses," "antecedent skepticism," and "Academic skepticism." RESUMO Na seção XII da Primeira Investigação, Hume refere-se a duas escolas céticas antigas ao apresentar sua própria visão do ceticismo que, entretanto, depende do ceticismo antigo somente secundária e indiretamente. A compreensão humiana do ceticismo depende principalmente de Descartes e de filósofos pós-cartesianos como Pascal, Huet, Foucher e Bayle que reagiram ceticamente às principais doutrinas cartesianas, mas seguiram uma versão ou outra da dúvida metódica de Descartes. Embora todos estes filósofos sejam relevantes na seção XII, examinarei os tópicos da seção nos quais Descartes parece ser diretamente visado. Após uma seção introdutória sobre as leituras de Julia Annas e Richard Popkin da relação de Hume com, respectivamente, o ceticismo antigo e o moderno, examino o que Hume chama na seção XII da Investigação de "ceticismo consequente sobre os sentidos", "ceticismo antecedente" e "ceticismo acadêmico".

Descartes developed an elaborate theory of animal physiology that he used to explain functionally organized, situationally adapted behavior in both human and nonhuman animals. Although he restricted true mentality to the human soul, I argue that he developed a purely mechanistic (or material) ‘psychology’ of sensory, motor, and low-level cognitive functions. In effect, he sought to mechanize the offices of the Aristotelian sensitive soul. He described the basic mechanisms in the Treatise on man, which he summarized in the Discourse. However, (...) the Passions of the soul contains his most ambitious claims for purely material brain processes. These claims arise in abstract discussions of the functions of the passions and in illustrations of those functions. Accordingly, after providing an intellectual context for Descartes’s theory of the passions, especially by comparison with that of Tho- mas Aquinas, I examine its ‘machine psychology’, including the role of habituation and association. I contend that Descartes put forth what may reasonably be called a ‘psychology’ of the unensouled animal body and, correspondingly, of the human body when the soul does not intervene. He thus conceptually distinguished a mechanistically explicable sensory and motor psychology, common to nonhuman and human animals, from true mentality involving higher cognition and volition and requiring (in his view) an immaterial mind.

In two rarely discussed passages – from unpublished notes on the Principles of Philosophy and a 1647 letter to Chanut – Descartes argues that the question of the infinite extension of space is importantly different from the infinity of time. In both passages, he is anxious to block the application of his well-known argument for the indefinite extension of space to time, in order to avoid the theologically problematic implication that the world has no beginning. Descartes concedes that we always (...) imagine an earlier time in which God might have created the world if he had wanted, but insists that this imaginary earlier existence of the world is not connected to its actual duration in the way that the indefinite extension of space is connected to the actual extension of the world. This paper considers whether Descartes’s metaphysics can sustain this asymmetrical attitude towards infinite space vs. time. I first consider Descartes’s relation to the ‘imaginary’ space/time tradition that extended from the late scholastics through Gassendi and More. I next examine carefully Descartes’s main argument for the indefinite extension of space and explain why it does not apply to time. Most crucially, since duration is merely conceptually distinct from enduring substance, the end or beginning of the world entails the end or beginning of real time. In contrast, extension does not depend on any enduring substance besides itself. (shrink)

Resumen: Este artículo ofrece razones iniciales para interpretar en forma dia-léctica las “pruebas de la existencia divina” que Descartes ofrece en sus Meditaciones III y V. Primero indico algunos precedentes entre los comentaristas contemporáneos y señalo cómo esa manera de abordar los problemas funda-mentales arranca en los clásicos griegos. Después muestro cómo un procedi-miento dialéctico podría resolver un conjunto de problemas que, en principio, incluye el tradicional “círculo cartesiano”. Por último, intento mostrar que no es impensable atribuirle a Descartes una (...) argumentación metafísica del tipo indicado; para ello, esgrimo un pequeño conjunto de argumentos textuales. Mi conclusión es que este tipo de interpretaciones merecen explorarse con mayor esmero.: This paper intends to sketch an initial reason for reading in a dialec-tical way the “proofs of God’s existence” in Descartes’ Meditations, III and V. I begin by indicating antecedents for this kind of interpretation among com-mentators, and show how this approach towards basic philosophical prob-lems can be traced to the Greek classics. I then try to explain how this ar-gumentative procedure can afford in principle a solution to the well-known riddle of the “Cartesian circle”, among other related issues. Finally, I discuss a small set of textual points and show that attributing a dialectical character to Descartes’ main metaphysical arguments should not be taken to be implausi-ble at all. I conclude that interpretations of this kind deserve a more careful exploration. (shrink)

My dissertation has two main parts. In the first half, I draw out an underlying presupposition of Descartes' philosophy: what I term "atomism of thought." Descartes employs a radical procedure of doubt in order to show that the first principle of his philosophy, the cogito, is an unshakeable foundation of knowledge. In the dialogue that follows his dissemination of the Meditations, Descartes reveals that a whole set of concepts and rational principles innate in our minds are never doubted. These fundamental (...) units of thought are indivisible, distinct, and isolated, and enable the possibility of any rational demonstration. Atoms of thought are perfectly individuated because God has created them as such. Likewise, our minds have been fashioned such that we necessarily have a clear and distinct perception every time we alight upon these simple notions. In the second part of the dissertation, I take up critiques of Descartes' view given by Nietzsche and Heidegger. In the chapter on Nietzsche, I attempt to fill a lacuna in scholarship about Nietzsche's commentary on Descartes. More specifically, I argue that once the foundation of God is displaced, the basis for accepting atomism of thought dissolves. In the final chapter, I analyze Heidegger's critique of Cartesian atomism. I first look at Heidegger's critique of classical truth as correspondence from Being and Time, and show how it is relevant to a critique of atomism. Then I show how the early Heidegger's holistic philosophical framework can provide an alternative that avoids the pitfalls of atomism. While I limit the scope of my analysis to Descartes' particular formulation, atomism of thought was an influential doctrine throughout modern philosophy. This aspect of Cartesianism has persisted and continues to be a significant theoretical underpinning of many contemporary views. It is my contention that Nietzsche and Heidegger have important contributions to make to this area of thought, and the relative neglect of their work in recent scholarship is a detrimental oversight.

The problem of philosophical skepticism relates to the difficulty involved in underwriting the claim that we know anything of spatio-temporal reality. It is often claimed, in fact, that proper philosophical scrutiny reveals quite the opposite from what common sense suggests. Knowledge of external reality is thought to be even quite obviously denied to us as a result of the alleged fact that we all fail to know that certain skeptical scenarios do not obtain. A skeptical scenario is one in which (...) we have neurological occurrences just like any normal situation in which we actually perceive spatio-temporal objects, but where we are deceived in some sense as a result of the manipulation of our brains from some outside source. In this work I attempt to address the problem of philosophical skepticism by claiming that most of us are able to come to know plenty about external reality, since we can come to realize that a certain philosophical theory of perception is correct. The theory I have in mind is what I call a non-cognitive theory of perception. According to this view, perceptual experience is defined by continuous, sensitive behavioral interaction with spatio-temporal objects of the appropriate size, shape, hardness, speed, etc. Knowing that this theory of perception is correct is equivalent to knowing that we know plenty about external reality. This is ultimately because by knowing that a non-cognitive theory of perception is true, we know that any skeptical scenario must fail to obtain. The structure of the work proceeds by first discussing the significance of the problem of philosophical skepticism in some detail. Chapter 1 lays out how the problem does indeed forcefully arise if it is conceded that we fail to know that the skeptical scenarios fail to obtain. Chapter 2 develops the sort of view of our epistemological situation that falls out of accepting without qualification that the problem exists. Chapter 3 examines and criticizes certain popular responses to the skeptical problem. The main goal of these first three preliminary chapters is to indicate that once it is admitted that we fail to know that the skeptical scenarios fail to obtain, the problem of philosophical skepticism forcefully presents itself. Chapter 4, however, attacks the idea that we fail to know that the skeptical scenarios fail to obtain. In this chapter I argue that this idea is wedded to the position that a certain theory of perception is correct. The theory in question is what I call a conjunctive theory of veridical experience. According to this view, normal experience of spatio-temporal objects occurs when a subject has a certain perceptual experience, and that experience also happens to match up with and/or be satisfied by what is really the case. Only when a theory of this sort is assumed, I argue, is the claim that we fail to know that the skeptical scenarios fail to obtain found to be obvious. In chapter 5 I argue that, in fact, a non-cognitive theory, rather than a conjunctive theory, is the correct view to maintain. In the final chapter 6 I develop the epistemological position that falls out of accepting a non-cognitive theory. (shrink)

Vyrauja nuomonė, jog ankstyvoji Descartes’o filosofija angažuojasi metodologinėms problemoms, o tai laikytina naujosios epochos ženklu. Tačiau turint omenyje tokios problematikos išskirtinį aktualumą Aristoteliui bei faktą, kad Descartes’o metodologija aiškiai stokoja apibrėžtumo, jo santykis su ankstesniąja tradicija turėtų būti įvertintas naujai. Straipsnyje siekiama apginti požiūrį, kad „Proto vadovavimo taisyklėse“, savo pirmajame filosofiniame veikale, Descartes’as demonstruoja pastangas duoti tvirtą epistemologinį pagrindą teorinio mąstymo išlaisvinimui iš bet kokių formalių apribojimų. Pateikdamas naują mąstymo procedūrų traktuotę, Descartes’as numato perspektyvų įvairovės galimybę teoriniame reiškinių aiškinime ir (...) šiuo aspektu atsiskleidžia jo originalumas. (shrink)

Central to Descartes’ philosophy is a view about immutable essences and eternal truths. After mentioning a Platonist account of recollection in Meditation V, Descartes declares that the ideas we have of mathematical notions “are not my invention but have their own true and immutable natures” (AT VII, 64/CSM II, 44).Descartes claims that other important philosophical notions, such as God, mind, body, and human free will (AT VII, 68; AT VIII-2, 348; AT III, 383; AT VII, 433, respectively), also have immutable (...) natures or essences. Although Descartes says a good many things about this view, nowhere does he offer definitive doctrine on the matter, and in fact frequently confuses his reader with apparently inconsistent pronouncements about immutable natures and eternal truths. In this essay, I focus on the immutable natures and propose a solution to two of the main problems associated with Descartes’ position, the metaphysical status of immutable natures and the purported indivisibility of their existence as ideas in the mind.
