Rene Descartes and William James had "body first" theories of the passions or emotions, according to which sensory stimulation causes a bodily response that then causes an emotion. Both held that this bodily response also causes an initial behavioral response (such as flight from a bear) without any cognitive intervention such as an "appraisal" of the object or situation. From here they differ. Descartes proposed that the initial processes that produce fear and running are entirely mechanical. Even human beings initially (...) run from the bear as a result of physiological processes alone, without mental contribution. These physiological processes also cause a mental passion, which is a cognitive representation of the situation (as regards novelty, benefit, or harm), and which motivates the will to continue the behavior already in progress. According to James, emotions are caused by instinctive bodily responses that are triggered by noncognitive but nonetheless conscious perceptual states. Emotions are bare feelings of internal physiological stirrings that accompany an instinctual response that has evolved through Darwinian natural selection. Jamesian emotions initially have no motivational or cognitive content, which they subsequently acquire through learning. The methodological legitimacy of comparing these positions across the centuries is defended, and the two theories are compared to recent theories. (shrink)

This chapter discusses Descartes thoughts on the seat of the soul or that part of the body which the soul is directly and intimately united. Descartes explains the simplicity principle: If the soul is simple, or indivisible, it can interact directly with only one object at once, thus indivisible. For example, if an animal's heart is taken and cut into pieces, the soul's indivisibility means that the soul cannot act directly upon the dissected parts of the heart. Descartes also consistently (...) identified the pineal gland as the seat of the soul— partly because it was mobile, durable, protected from outside influence, and accessible to the nerves. It also explains that the mind is not affected by all parts of the body, but only the brain and one small part of the brain only where a certain part of the brain is affected while other parts are doing other things. This chapter finally reveals that the simplicity principle of Descartes will have strong difficulties in the final analysis in relation to the truth of God. (shrink)

Although the basis of modern biology is Cartesian, Descartes’s theories of biology have been more often ridiculed than studied. Yet, Dennis Des Chene demonstrates, the themes, arguments, and vocabulary of his mechanistic biology pervade the writings of many seventeenth-century authors. In his illuminating account of Cartesian physiology in its historical context, Des Chene focuses on the philosopher’s innovative reworking of that field, including the nature of life, the problem of generation, and the concepts of health and illness. Des Chene begins (...) by surveying works that Descartes would likely have encountered, from late Aristotelian theories of the soul to medical literature and treatises on machines. The Cartesian theory of vital operations is examined, with particular attention to the generation of animals. Des Chene also considers the role of the machine-model in furnishing a method in physiology, the ambiguities of the notion of machine, and of Descartes’s problem of simulation. Finally, he looks at,the various kinds of unity of the body, both in itself and in its union with the soul. Spirits and Clocks continues Des Chene’s highly regarded exploration -- begun in his previous book, Life’s Form -- of the scholastic and Cartesian sciences as well as the dialogue between these two worldviews.

Descartes understood the subject matter of physics (or natural philosophy) to encompass the whole of nature, including living things. It therefore comprised not only nonvital phenomena, including those we would now denominate as physical, chemical, minerological, magnetic, and atmospheric; it also extended to the world of plants and animals, including the human animal (with the exception of those aspects of the human mind that Descartes assigned to solely to thinking substance: pure intellect and will). Descartes wrote extensively on physiology and (...) on the physiology and psychology of the senses. This chapter examines the notions of *physiology* and *psychology* in medical and natural philosophical works of Descartes' day; follows his efforts to bring physiology into his mechanistic idiom; considers the relation between physiology of the animal machine and psychological functions that yield functionally appropriate behavior; goes into his physiology and psychology of vision; and elaborates the tension in Descartes' works between his metaphysically supported micro-corpuscularism and his discussion of the animal machine as an organic unity comprising various functionally and teleologically characterized systems. The chapter draws on Descartes' works in both metaphysics and natural philosophy, including his Treatise on Man (originally published as L'Homme, 1664). (shrink)

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.

Volumes I and II provided a completely new translation of the philosophical works of Descartes, based on the best available Latin and French texts. Volume III contains 207 of Descartes' letters, over half of which have previously not been translated into English. It incorporates, in its entirety, Anthony Kenny's celebrated translation of selected philosophical letters, first published in 1970. In conjunction with Volumes I and II it is designed to meet the widespread demand for a comprehensive, authoritative and accurate edition (...) of Descartes' philosophical writings in clear and readable modern English.

The Philosophical Writings of Descartes VOLUME 3. Volumes 1 and 2 provide a completely new translation of many of the major works in metaphysics, epistemology, and natural philosophy.

Principles of Philosophy was written in Latin by Rene Descartes. Published in 1644, it was intended to replace Aristotle's philosophy and traditional Scholastic Philosophy. This volume contains a letter of the author to the French translator of the Principles of Philosophy serving for a Preface and a letter to the most serene princess, Elizabeth, eldest daughter of Frederick, King of Bohemia, Count Palatine, and Elector of the Sacred Roman Empire. Principes de philosophie, by Claude Picot, under the supervision of Descartes, (...) appeared in 1647 with a letter-preface to Queen Christina of Sweden. (shrink)

Descartes and William Harvey engaged in a polite dispute about the cause of the heart's motion. Descartes saw the heart's motion of passive; Harvey saw it as active. I criticize three prominent explanations for Descartes' opposition to Harvey's theory. I argue that Descartes found Harvey's model to be inconsistent with mind-body dualism and this was the reason he opposed it.

This anthology of the work of Baruch de Spinoza presents the text of Spinoza's masterwork, the Ethics, in what is now the standard translation by Edwin Curley. Also included are selections from other works by Spinoza, chosen by Curley to make the Ethics easier to understand, and a substantial introduction that gives an overview of Spinoza's life and the main themes of his philosophy. Perfect for course use, the Spinoza Reader is a practical tool with which to approach one of (...) the world's greatest but most difficult thinkers, a passionate seeker of the truth who has been viewed by some as an atheist and by others as a religious mystic. The anthology begins with the opening section of the Treatise on the Emendation of the Intellect, which has always moved readers by its description of the young Spinoza's spiritual quest, his dissatisfaction with the things people ordinarily strive for--wealth, honor, and sensual pleasure--and his hope that the pursuit of knowledge would lead him to discover the true good. The emphasis throughout these selections is on metaphysical, epistemological, and religious issues: the existence and nature of God, his relation to the world, the nature of the human mind and its relation to the body, and the theory of demonstration, axioms, and definitions. For each of these topics, the editor supplements the rigorous discussions in the Ethics with informal treatments from Spinoza's other works. (shrink)

A major contribution to Descartes studies, this book provides a panorama of cutting-edge scholarship ranging widely over Descartes's own primary concerns: metaphysics, physics, and its applications. It is at once a tool for scholars and--steering clear of technical Cartesian science--an accessible resource that will delight nonspecialists. The contributors include Edwin Curley, Willis Doney, Alan Gabbey, Daniel Garber, Marjorie Grene, Gary Hatfield, Marleen Rozemond, John Schuster, Dennis Sepper, Stephen Voss, Stephen Wagner, Margaret Welson, Jean Marie Beyssade, Michelle Beyssade, Michel Henry, Evert (...) van Leeuwen, Jean-Luc Marion, Genevieve Rodis-Lewis, and Jean-Pierre Seris. Combining new textual sensitivity with attentiveness to history, they represent the best established scholars and most exciting new voices, including both English speaking and newly-translated writers. Part I examines the foundations of Descartes's philosophy: Cartesian certainty; the phenomenology of the cogito and its modulations in the passions; and the defensibility and comprehensibility of the Cartesian God. The second part examines Descartes's groundbreaking metaphysics: mind's distinctness from and interaction with body; imagination; perception; and language. Part III examines Cartesian science: the revolutionary rhetoric of the Rules and the Discourse; the metaphysical foundations of physics; the interplay of rationalism and empiricism; the mechanics and human biology that flow from Descartes's physics.

Dernier ouvrage publie par Descartes, le Traite des Passions de l'ame (1649) est le fruit de toute sa philosophie. Ce traite, qui s'appuie sur un resume de la biologie cartesienne, s'oriente vers une medecine concrete des affections psycho-physiologiques et s'epanouit en une apologie de la generosite. Aux observations scientifiques, Descartes ne dedaigne pas d'adjoindre des notations psychologiques dont la finesse evoque parfois ces maximes qui fleurissaient dans les salons au XVIIe siecle. Ainsi l'ampleur des conclusions scientifiques, morales et metaphysiques, sources (...) d'etudes toujours renaissantes pour les specialistes, se colore par surcroit d'une richesse vecue qui fait de ce Traite, ecrit pour une princesse et offert a une reine, le modele des ouvrages accessibles au plus grand public.
