In this paper, I aim to address a specific issue underpinning Cartesian metaphysics since its first public appearance in the Discourse right up until the Meditations, but which definitely came to the surface in the Second and Fifth Replies. It involves the possibility that to be thinking and to be extended do not actually contrast as two entirely different properties; hence, these two essences cannot serve as the basis for a disjunctive, real distinction between two corresponding substances, the mind and (...) the body. I dub this problem the ‘thinking matter issue.’ I suggest that Descartes’s concerns about the ‘thinking matter issue’ characterizes and structures the entirety of Meditation Two and its connection with Meditation Six, especially in the attempt to covertly implement what I refer to as Descartes’s ‘prejudice strategy.’ The core of the ‘prejudice strategy’ lies in the idea that the ‘thinking matter issue’ is just a false problem, one raised by the inadequate notions of the mind and the body that we apply to this problem. In section 1, I set out the way in which the ‘thinking matter issue’ emerged in Descartes’s philosophy after the first exposition of his metaphysics in the Discourse. Section 2 deals with the new argumentative path Descartes draws for the Meditations and with the new role that he assigns to the inference about the mind’s non-physical nature after the cogito. In section 3, I contend that the ‘prejudice strategy’ structures Meditation Two and, partially, Six. Section 4 shows that Descartes himself reveals this in his Replies to the Second and the Fifth Set of Objections. In section 5, I delve into Descartes’s foundational theory of the ‘prejudice strategy,’ i.e. his theory of infancy as set out especially in the Replies to the Sixth Set of Objections. -/- . (shrink)

In this paper, I address the issue of whether the evil demon could have caused the idea of God. In order to determine the capabilities of the evil demon, I perform a thought experiment in which I reaffirm the con-clusion that an imperfect being could have never caused an idea of perfection and infinitude, i.e., the idea of God. The article is divided into five sections and a conclusion. While the first section is introductory, the second looks at the problem (...) of God and knowledge certainty. Elucidating how reality is gradual according to Descartes, in the third section I address the distinction between objective, formal and eminent reality. In turn, in the fourth section, I argue that if the objective reality of God exists, that is, an idea of perfection, the imperfect evil demon could have never caused it. The last section examines the reverse argument of the fourth section, viz, whether God could have caused the existence of evil and imperfection. (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)

I argue that Descartes intended the so-called ontological "argument" as a self-validating intuition, rather than as a formal proof. The textual evidence for this view is highly compelling, but the strongest support comes from understanding Descartes's diagnosis for why God's existence is not 'immediately' self-evident to everyone and the method of analysis that he develops for making it self-evident. The larger aim of the paper is to use the ontological argument as a case study of Descartes's nonformalist theory of deduction (...) and his method of analysis, showing how he conceives the latter as a form of philosophical therapy.

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.

Descartes notoriously characterizes substance in two ways: first, as an ultimate subject of properties ; second, as an independent entity. The characterizations have appeared to many to diverge on the definition as well as the scope of the notion of substance. For it is often thought that the ultimate subject of properties need not—and, in some cases, cannot—be independent. Drawing on a suite of historical, textual, and philosophical considerations, this essay argues for an interpretation that reconciles Descartes's two characterizations. It (...) proposes that both characterizations invoke a type of independence that obtains just in case there is no relation to another entity that holds by the nature of the entity in question. Even though the ultimate subject of properties is sometimes not independent in other respects, it satisfies this independence-by-nature condition. (shrink)

Abstract Descartes's theory of volition as expressed in his Passions of the Soul is analyzed and outlined. The focus is not on Descartes's proposed answers to questions about the nature and processes of volition, but on his way of formulating questions about the nature of volition. It is argued that the assumptions underlying Descartes's questions have become ?intellectual strait?jackets? for all who are interested in volition: neuroscientists, philosophers and psychologists. It is shown that Descartes's basic assumption?that volition causes change in (...) the brain/mind, not in the world around us?has set in train a series of ?themata? that have dominated studies of the will, severely curtailing our understanding. It is then shown that these Cartesian themata are so limiting and confusing that a number of internally contradictory ideas have actually become mainstays of most theories of volition; in particular, the concepts of unconscious sensations and of involuntary volitions.

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 this paper, I have made an attempt to understand the concept of moral certainty in Descartes’ philosophy. This concept has not received much attention in the Cartesian scholarship. I argue that Descartes entertains a certainty, called moral certainty, which is a lesser certainty than metaphysical certainty, which we see in his text, Meditations. Only a few Cartesian scholars have talked about this concept in relation to other areas in Descartes’ philosophy. In this paper, I draw a relationship between the (...) concept of moral certainty and the faculty of reason in the context of Descartes’ text, Discourse. I argue that Descartes entertains the testimonies of learned men when it comes to practical or moral matters, arguing that their testimonies guarantee moral certainty. I argue that Descartes claims, in the Discourse, that human beings are endowed with the faculty of reason on the basis of moral certainty. (shrink)

This paper serves to introduce the papers from the symposium by the same title, by describing the sort of work done in philosophy of psychology conceived as a branch of the philosophy of science, distinguishing it from other discussions of psychology in philosophy, and criticizing the claims to set limits on scientific psychology in the largely psychologically uninformed literatures concerning "folk psychology' and "wide" and "narrow" content. Philosophy of psychology as philosophy of science takes seriously and analyzes the explanatory structures, (...) conceptual problems, and evidentiary practices of extant scientific psychology.

Recent Cartesian scholarship postulates two Descartes, separating Descartes into a scientist and a metaphysician. The purpose varies, but one has been to show that the metaphysical Descartes, of the Meditations, is less genuine than the scientific Descartes. Accordingly, discussion of God and the soul, the evil demon, and the non-deceiving God were elements of rhetorical strategy to please theologians, not of serious philosophical argumentation. I agree in finding two Descartes, but the two I identify are not scientist and philosopher, but (...) practitioner and methodologist of the mathematical sciences on the one hand, and metaphysician of a new, general science of nature on the other. This chapter examines the transition to the second Descartes, and especially the metaphysical turn. It proposes that although Descartes' doubt was methodological and he felt no serious threat from skepticism and absolute certainty was not his primary goal. Rather, the doubt was used to reform the intellect, or to teach the use of the pure intellect (and to obtain certainty in that domain). Further, Descartes' metaphysics was primarily in the service of his natural philosophy (where in the main he did not claim absolute certainty). He did not talk about God and the soul in order to fool the theologians. His discussion of the relation between God and human reason was part of a metaphysical strategy in which, through his doctrine on the eternal truths, he separated knowledge of the first principles of natural philosophy (gained by the natural light) from theological cognition (through the light of grace), thereby seeking to render his metaphysics distinct from the proper domain of theology.

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)

The mind-body problem in philosophy is typically understood as a discourse concerning the relation of mental states to physical states, and the experience of sensation. On this level it seems to transcend issues of race and racism, but Another Mind-Body Problem demonstrates that racial distinctions have been an integral part of the discourse since the Modern period in philosophy. Reading figures such as Descartes, Leibniz, and Kant in their historical contexts, John Harfouch uncovers discussions of mind and body that engaged (...) closely with philosophical and scientific notions of race in metaphysics and the philosophy of mind, in particular in understanding how the mind unites with the body at birth and is then passed on through sexual reproduction. Kant argued that a person’s exterior body and interior psyche are bound together, that non-White people lacked reason, and that this lack of reason was carried on through reproduction such that non-Whites were an example of a union of mind and body without full being. Charting the development of this phenomenon from sixteenth-century medical literature to modern-day race discourse, Harfouch argues for new understandings of Descartes’s mind-body problem, Fanon’s experience of being ‘not-yet human,’ and the place of racism in relation to one of philosophy’s most enduring and canonical problems. -/- “Harfouch has written an important book on the intersection of race and the Western construction of the mind-body problem … This book is a significant resource for theorists dealing with race and decolonization issues, but it is more significant for the critique of philosophy itself and the continued teaching of mind-body issues. Readers will need some knowledge of philosophy, but the volume is in general accessible. It should be required reading for scholars of philosophy. Harfouch establishes a logically strong argument and makes a unique contribution to the field.” — CHOICE. (shrink)

I argue that Lisa Shapiro’s rational reconstruction of Descartes’s provisional moral code in terms of a broad conception of morality supplies us with an interpretative framework that make historiographical sense of the reception of Descartes’s moral philosophy in an Anglophone context on three occasions: the appeal to Descartes made by Henry More, Henry Sidgwick’s abrupt dismissal, and the ensuing reaction to Sidgwick found in Grace Neal Dolson. This case shows, I maintain, how reception history can be utilized to inform and (...) support rational reconstruction of philosophical texts. (shrink)

Alison Simmons, in Simmons (1999), argues that Descartes in Meditation Six offered a teleological account of sensory representation. According to Simmons, Descartes’ view is that the biological function of sensations explains both why sensations represent what they do (i.e., their referential content) and why they represent their objects the way they do (i.e., their presentational content). Moreover, Simmons claims that her account has several advantages over other currently available interpretations of Cartesian sensations. In this paper, I argue that Simmons’ teleological (...) account cannot be sustained for both theoretical and textual reasons and that it does not have the advantages it is claimed to have. (shrink)
