Descartes afirma que el cogito se "experimenta en uno" (apud se experiatur)o se "siente en uno mismo" ("il sent in lui-même"), pero también ha señalado que uno no siente sino a través del cuerpo. El problema es que, en las Meditaciones, el cogito fue caracterizado cuando todavía no se había demostrado la existencia del cuerpo. Pese a esto, Descartes parece haberse dejado influir por ciertas sensaciones internas de duda y certeza. En el trabajo se sostiene que esto fue posible porque (...) esas sensaciones internas son efecto de una ratio implícita: la existencia de un Dios no engañador. (shrink)

At the crux of Descartes's general metaphysics and epistemology are his accounts of substances, attributes and ideas of substances and attributes. In spite of the centrality of these theories, there is wide disagreement among scholars about how to interpret them. I approach these debates by focusing on Descartes's theory of the infinite substance ? God. I argue that God's attributes are neither individual, inseparable properties that inhere in God (contra Kenny, Wilson, Curley, Hoffman) nor deductions from God (contra Lennon), but (...) attributions that can consistently be made to God. On this account, the diversity of God's attributes is due to how meditators refer to the various cognitive routes they take to clear and distinct perceptions of God; what makes a meditator's clear and distinct perception of God more distinct is that it becomes more stable ? the meditator can more easily retain and regain the perception. Other virtues of this interpretation include accounts of the following: the puzzling remarks about essences that Descartes makes to Gassendi; what founds conceptual distinctions in reality; and why the Cartesian meditator ?proves? the existence of God several times in the Meditations.

Many contemporary social epistemologists take themselves to be combatting an individualist approach to knowledge typified by Descartes. Although I agree that Descartes presents an individualist picture of scientific knowledge, he does allow some practical roles for reliance on the testimony and beliefs of others. More importantly, however, his reasons for committing to individualism raise important issues for social epistemology, particularly about how reliance on mere testimony can propagate prejudices and inhibit genuine understanding. The implications of his views are worked out (...) more fully by some of his immediate successors; I examine how François Poulain de la Barre, and (briefly) Mary Astell analyze the social conditions for epistemic agency in a Cartesian vein.

In the Fifth Meditation Descartes considers the problem of knowledge preservation : the challenge of accounting for the diachronic certainty of perfect knowledge [scientia]. There are two general solutions to PKP in the literature: the regeneration solution and the infallible memory solution. While both readings pick up on features of Descartes’ considered view, I argue that they ultimately fall short. Salvaging pieces from both readings and drawing from Descartes’ virtue theory, I argue on textual and systematic grounds for a dispositionalist (...) solution. On this view, the diachronic certainty of scientia is achieved through virtuous habits of belief. (shrink)

With the systematic aim of clarifying the phenomenon sometimes described as “the intellectual apprehension of first principles,” Descartes’ first principle par excellence is interpreted before the historical backcloth of Aristotle’s Posterior Analytics. To begin with, three “faces” of the cogito are distinguished: (1) the proto-cogito (“I think”), (2) the cogito proper (“I think, therefore I am”), and (3) the cogito principle (“Whatever thinks, is”). There follows a detailed (though inevitably somewhat conjectural) reconstruction of the transition of the mind from (1) (...) via (3) to (2) and back again to (3). What emerges is, surprisingly, a non-circular, non-logical, and ultimately non-mysterious process by which first principles implicitly contained in a complex intuition are gradually rendered explicit (and, if abstract, grasped in their abstract universality). This process bears a striking family resemblance to that intuitive induction (“grasping the universal in the particular”) which Aristotle scholars have distinguished from empirical forms of induction.

Clear and distinct perception is the centrepiece of Descartes’s philosophy — it is the source of all certainty — but what does he mean by ‘clear’ and ‘distinct’? According to the prevailing approach, what it means for a perception to be clear is that its content has a certain objective property, like truth. I argue instead that clarity is at least partly a subjective, phenomenal quality whereby a content is presented as true to the perceiving subject. Clarity comes in degrees. (...) Any weak degree of clarity, available to the senses, can be merely subjective, since what it presents as true may not actually be true. But complete clarity, available to intellectual perception, has an objective dimension, since what it presents as true is always some truth, some bit of reality. Further, I argue that the other perceptual qualities that Descartes identifies — obscurity, confusion, and distinctness — are all defined in terms of clarity. Of particular note is the fact that distinctness is not a positive feature to be added to clarity: a distinct perception is just a completely clear perception. (shrink)

Generalmente los comentadores han abordado la temática de la intuición en la filosofía de Spinoza desde la perspectiva de la problemática de lo que en la Ética aparece como ciencia intuitiva o tercer genero de conocimiento. En el presente artículo, en cambio, intentamos mostrar que hay en los escritos de Spinoza un concepto de intuición más amplio que el que está implícito en la ciencia intuitiva, del cual esta no sería más que una subespecie. Como paso previo para alcanzar dicho (...) fin, intentaremos mostrar que la concepción de la intuición que sostiene Spinoza está estrechamente emparentada con la concepción cartesiana -de la cual ofrecemos un breve esbozo en el primer apartado- y que ambas concepciones tienen como fundamento la naturaleza de la idea. Generally, critics had tackle the issue of intuition in Spinoza’s philosophy from the point of view of the problem of what in the Ethics is called intuitive science or third kind of knowledge. In the present paper, instead, we try to show that there is in Spinoza`s writings a wider concept of intuition than that which is implied in the intuitive science, being the later no more than a sub-kind of the former. As a previous step to achieve this target, we try to show that Spinoza`s conception of intuition is narrowly tied with the Cartesian conception -of which we offer a brief draft in the first part- and that both conceptions are based on the nature of the idea.

Descartes is not widely recognized for his ethics; indeed, most readers are unaware that he had an ethics. However, Descartes placed great importance on his ethics, claiming that ethics is the highest branch of his philosophical system. I aim to understand the systematic relationship Descartes envisions between his ethics and the rest of his philosophy, particularly his metaphysics and epistemology. I defend three main theses. First, I argue against the recent trend in the literature that claims that the chief virtue (...) in Descartes’ ethics—generosity—is acquired in the Meditations. On this view, the presence of moral virtue in the Meditations shows that ethical practice is intertwined with metaphysics and epistemology. I argue that generosity cannot be acquired in the Meditations because acquiring generosity presupposes several metaphysical and physical truths that the meditator cannot access given her epistemic position. Thus, I maintain that metaphysics and epistemology is foundational to ethics. Second, I resolve the tension between Descartes’ description of distinct virtues, and his insistence that there is only a single virtue—the disposition to judge well. Drawing from his theory of conceptual distinction in his metaphysics, I argue that Descartes offers a unique account of the unity of the virtues. Although Descartes describes different virtues, he thinks that all of them are identical to each other because they are reducible to the disposition to judge well. Nonetheless, we can conceptually distinguish between the virtues because we can regard the disposition to judge well in different ways given the various applications it has in different types of moral situations. Third, I show that some of Descartes’ ethical concepts inform his epistemology. I draw from Descartes’ theory of virtue to address “the problem of knowledge preservation,” that is, how to render perfect knowledge— scientia—stable in light of the instability of clear and distinct perceptions. I argue that Descartes intends to preserve scientia by grounding items of scientia in virtuous habits of belief. These habits of belief are established through repeated engagement with cognitive routes to clear and distinct perceptions, and are ultimately grounded in memory. This reading has the advantage of explaining Descartes’ notoriously confusing remarks about memory in response to the Cartesian circle. (shrink)

Descartes claims that God is a substance, and that mind and body are two different and separable substances. This paper provides some background that renders these claims intelligible. For Descartes, that something is real means it can exist in separation, and something is a substance if it does not depend on other substances for its existence. Further, separable objects are correlates of distinct ideas, for an idea is distinct (in an objective sense) if its object may be easily and clearly (...) separated from everything that is not its object. It follows that if our idea of God is our most distinct idea, as Descartes claims, then God must be a substance in the Cartesian sense of the term. Also, if we can have an idea of a thinking subject which does not in any sense refer to bodily things, and if bodily things are substances, then mind and body must be two different substances.

According to Kemp Smith, Descartes believed that animals were devoid of feelings and sensations. This is the so-called ‘monstrous thesis,’ which I explore here in light of two Cartesian approaches to animals. Firstly, I examine their original treatment in function of Descartes’ early metaphysical approach, i.e., all natural phenomena are to be elucidated in terms of mental scrutiny. As pain would only exist in the understanding, and animals have neither understanding nor souls, Descartes held that they did not suffer. Secondly, (...) I look at the Cartesian late naturalism; specifically, at how animals are subsequently regarded as machines that may suffer. Lastly, I conclude that the ‘monstrous thesis’ is not Cartesian because animals are machines with feelings and sensations. However, Descartes’ surprising indulgence towards humans who kill and eat animals supposes that empathy for beings who may suffer is not necessary. This may raise doubts as to another ‘monstrous thesis.'. (shrink)

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)
