What knowledge is imperilled by sceptical doubt? That is, what range of beliefs may be called into doubt by sceptical nightmares like the Cartesian demon hypothesis? It is generally thought that demons have limited powers, perhaps only threatening a posteriori knowledge of the external world, but at any rate not threatening principles like the cogito. I will argue that there is a demon – the debasing demon – with unlimited powers, which threatens universal doubt. Rather than deceiving us with falsities, (...) the debasing demon would allow us true beliefs, but only as guesses. (shrink)

Descartes is widely portrayed as the arch proponent of “the epistemological transparency of thought” (or simply, “Transparency”). The most promising version of this view—Transparency-through-Introspection—says that introspecting (i.e., inwardly attending to) a thought guarantees certain knowledge of that thought. But Descartes rejects this view and provides numerous counterexamples to it. I argue that, instead, Descartes’s theory of self-knowledge is just an application of his general theory of knowledge. According to his general theory, certain knowledge is acquired only through clear and distinct (...) intellection. Thus, in his view, certain knowledge of one’s thoughts is acquired only through clear and distinct intellection of one’s thoughts. Introspection is a form of intellection and it can be clear and distinct. Ordinarily, however, introspection isn’t clear and distinct but is instead confused with dubitable perceptions of bodies. To make introspection clear and distinct, we need to “sharply separate” it from all perceptions of bodies by doubting all perceptions of bodies. Without such radical doubt, introspection remains confused and we lack certain knowledge not just of the specific features of our thoughts, but even of the minimal claim that a thought exists. Far from being the high priest of Transparency, Descartes is radically opposed to it. (shrink)

This article explores the vocabulary of knowing in Descartes’ Meditations. It offers a detailed and in part sequential examination of his use of cognitio and scien...

Descartes’ metaphysical project revolves around the themes of the self, God, and the external world. He takes the self as a thinking substance by separating it from the extended substance. Unlike God – the uncreated substance – the self and the external world are considered to be created substances. This paper has three objectives. The first is to find out Descartes’ answer to the question of what the self and the external world are by examining existence and persistence. The second (...) is to show how Descartes demonstrates the self-getting access to this world. The last is to point out the deficiency in his metaphysical project, namely, the deficiency in his accounts of the self, the external world, and the relation between them. This paper attempts to make up for this deficiency by putting the missing piece, i.e., time into its place. (shrink)

Znaczenie epistemiczne aktualnie jasnych i wyraźnych ujęć w epistemologii Kartezjusza W niniejszym artykule omawiam kwestię dotyczącą roli, jaką Kartezjusz wyznaczył w budowie gmachu wiedzy pewnej temu, co można określić mianem aktualnie jasnych i wyraźnych ujęć. Powyższa kwestia jest od dawna przedmiotem ożywionej dyskusji wśród komentatorów epistemologii Kartezjusza. W współczesnej literaturze historyczno-filozoficznej spotkać można dwie zasadnicze interpretacje na temat funkcji jaką pełnią w systemie Kartezjusza aktualnie jasne i wyraźne ujęcia. Pierwszą można nazwać interpretacją psychologiczną, drugą zaś normatywną. Ta ostatnia głosi, że (...) aktualnie jasne i wyraźne ujęcia są całkowicie odporne na wątpienie zanim jeszcze dowiedzie się istnienia Boga i ustali ogólną regułę prawdy. Z tego względu ich pewność nie ogranicza się u Kartezjusza jedynie do pewności psychologicznej, lecz ma charakter normatywny. Opowiadam się za interpretacją normatywną. Przemawiają za nią – moim zdaniem – liczne racje. Ale rodzi ona także pewne trudności. Dlatego po przedstawieniu argumentów przemawiających na jej rzecz i niewątpliwych zalet wynikających z jej przyjęcia, omawiam szczegółowo pewne trudności zarówno tekstowe, jak i merytoryczne, którym musi sprostać ta interpretacja, jeśli mamy ją utrzymać.

La epistemología contemporánea sostiene la imagen de Descartes como un fundamentalista epistemológico clásico, apelando, para ello, a las certezas metafísicas y a la presunta deducción del resto de conocimiento a partir de dichos principios. Con todo, un examen más detallado del proyecto epistemológico cartesiano pone en cuestión esta interpretación. El presente artículo analiza el papel de la deducción y la certeza moral a fin de redefinir el fundamentalismo de Descartes en términos moderados.

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.

Research questions in mainstream epistemology often take for granted a cognitive internalist picture of the mind. Perhaps this is unsurprising given the seemingly safe presumptions that knowledge entails belief and that the kind of belief that knowledge entails supervenes exclusively on brainbound cognition. It will be argued here that the most plausible version of the entailment thesis holds just that knowledge entails dispositional belief. However, regardless of whether occurrent belief supervenes only as the cognitive internalist permits, we should reject the (...) idea that dispositional belief supervenes only in cognitive internalist-friendly ways. These observations, taken together, reveal two things: first, that a cognitive internalist picture of the mind is much more dispensable in epistemology than has been assumed and, second, that pursuing questions in extended epistemology need not involve any radical departure from the commitments of more traditional epistemological projects.

Self-verifying judgments like _I exist_ seem rational, and self-defeating ones like _It will rain, but I don’t believe it will rain_ seem irrational_._ But one’s evidence might support a self-defeating judgment, and fail to support a self-verifying one. This paper explains how it can be rational to defy one’s evidence if judgment is construed as a mental performance or act, akin to inner assertion. The explanation comes at significant cost, however. Instead of causing or constituting beliefs, judgments turn out to (...) be mere epiphenomena, and self-verification and self-defeat lack the broader philosophical import often claimed for them.

Con excepción de Aristóteles, no hay quizá ningún otro filósofo al que Hegel se haya referido repetidamente en forma tan elogiosa como Descartes. Descartes es para Hegel quien por primera vez en la Historia de la Filosofía, antes que Fichte, advierte que la autoconciencia es un momento esencial de la objetividad del conocimiento humano y convierte así a la actividad como tal del pensar en principio fundamental de la filosofía. La introducción de este nuevo paradigma, a saber: el idealista, implica (...) una verdadera revolución teórica, cuyos corolarios los autores posteriores a Descartes intentan explicitar. En el contexto de este proceso de explicitación, Hegel - a primera vista, curiosamente - contrapone el pensamiento de Kant al de Descartes: si bien, por un lado, profundiza el modelo idealista, Kant, por el otro, hipostasia a ojos de Hegel el representacionalismo y, con ello, los elementos realistas presentes en el idealismo cartesiano. Para Hegel, la absolutización del principio idealista propuesto por Descartes significa, por el contrario, un retorno al espíritu genuino de su pensamiento. El idealismo absoluto se entiende, en efecto, como la consumación de un modelo teórico novedoso en filosofía. Ahora bien, no sólo el verdadero sentido de este modelo, sino ante todo su potencialidad explicativa en relación a los problemas fundamentales de la filosofía han pasado frecuentemente inadvertidos. Mediante el análisis de algunas tesis centrales en su proceso de constitución, en nuestra comunicación intentaremos arrojar luz sobre la naturaleza del paradigma del idealismo absoluto y, sobre esta base, examinaremos su relevancia para la problemática filosófica del presente en el ámbito de la teoría del conocimiento y la ontología.

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)

We want to study the expansion of subjectivity in Descartes' philosophy, so we all know that subjectivity is the foundation of the human self in the realms of epistemology, cosmology, ethics, art, religion, and science. This article shows that Descartes's general skepticism led him to subjectivity because after he doubted everything, he found himself as the first and only certain being, and then he considered the principle of "I think, therefore I am" (_Cogito_) as the foundation of cognition and every (...) being in the world, including the being of God and corporal substances. Descartes considered the human reason to be independent of everything other than reason itself respecting the matter (problem) of cognition, and, in this direction, he resorts to the mental innate concepts to shape the scientific construction itself. Subjectivity (the human self) embraces all aspects of Descartes' philosophy, and in this philosophy, the whole world appears as a set of objects, and the universe (cosmos) has no other truth than the image that the human being made from it. Therefore, the only real subject is nothing but the human self. Descartes' subjectivity changed the course of modern philosophy, and later philosophers philosophized in that direction. Descartes's philosophy, and in particular his epistemology, is based on the mind. It begins with the mind and continues with the mind, and ends with the human mind. And this is the culmination of the broad scope of subjectivism in René Descartes's philosophy, and our goal was to emphasize the breadth of subjectivism. (shrink)

Self-consciousness can be understood as the ability to think I-thou-ghts which can be described as thoughts about oneself ‘as oneself’. Self-consciousness possesses two specific correlated features: the first regards the fact that it is grounded on a first-person perspective, whereas the second concerns the fact that it should be considered a consciousness of the self as subject rather than a consciousness of the self as object. The aim of this paper is to analyse a few considerations about Descartes and Hume’s (...) approaches to self-consciousness, as both philosophers introduce a first-personal method of accessing the subjective dimension through an introspective account. Descartes’s view on self-consciousness seems incapable of conceiving and recognizing herself as herself, while Hume’s seems to lack those features assigned to the consciousness of self-as-subject.

Descartes’s Meditations on First Philosophy, regarded by many as his masterpiece, has been the subject of significant philosophical debate since its publication in 1641. Yet the Meditations is remarkable not only for its philosophical ideas but also for the style in which it was written. Two of the most notable stylistic elements of the Meditations are the use of temporal markers—a significant departure from analogous philosophical treatises of the same period—and the fact that the text is written in such a (...) way as to invite readers to subsume themselves into the role of the narrator, so as to experience its arguments for themselves. Many commentators have hinted at the importance of the narrator. But there has been little attempt at a sustained engagement. The function of the text as a series of days of meditation has also been insufficiently explored. In order to further investigate the roles of time and narrative within the Meditations, this thesis uses various reading methods provided by narrative theory, with particular focus on Monika Fludernik’s experiential model of narrative. Fludernik’s model allows for a clearer articulation of the role readers play in enacting meaning, and the way in which readers will in a sense “author” a text on their own terms. Reading the Meditations as an experiential narrative also illuminates significant issues to do with Descartes’s distinction between geometric and discursive argument, his conception of time, the specific expression of the Cogito in the Meditations, and the “reorientation” at the heart of the text—which I am calling a sort of conversion. The conversion at the heart of the Meditations will be explored in parallel with Saint Augustine’s Confessions and Saint Ignatius of Loyola’s Spiritual Exercises, two texts which—like the Meditations—can be thought of as experiential narratives designed to bring about some kind of conversion. I argue that such an experiential reading, drawing on the roles of time and narrative in the text, offers to enrich our understanding of the Meditations. (shrink)

The aim of this dissertation is to provide a critique of the idea that skepticism was the driving force in the development of early modern thought. Historian of philosophy Richard Popkin introduced this thesis in the 1950s and elaborated on it over the next five decades, and recent scholarship shows that it has become an increasingly accepted interpretation. I begin with a study of the relevant historical antecedents—the ancient skeptical traditions of which early modern thinkers were aware—Pyrrhonism and Academicism. Then (...) I discuss the influence of skepticism on three pre-Cartesians: Francisco Sanches, Michel de Montaigne, and Pierre Charron. Basing my arguments on an informed understanding of both ancient Greek skepticism and some of the writings of these philosophers, I contend that it is inaccurate to predominantly characterize Sanches, Montaigne, and Charron as skeptics. To support his thesis about the singular influence of skepticism on early modern thought, Popkin says that René Descartes’ metaphysical philosophy was formed as a response to a skeptical threat and that Descartes ultimately conceded to the force of skepticism. He also argues that David Hume was a Pyrrhonist par excellence. I disagree with Popkin’s claims. I argue that Descartes was not as deeply affected by skepticism as Popkin suggests and that it is inaccurate to characterize Hume as a Pyrrhonist. By offering this critique, I hope to make clear to the readers two things: first, that Popkin’s thesis, though it is both enticing and generally accepted by many scholars, is questionable with regard to its plausibility; second, that the arguments I present in this dissertation reveal that further research into the role of skepticism in early modern philosophy is in order.

The term “consciousness” is very often, though not always, interchangeable with the term “awareness,” which is more colloquial to many ears. We say things like “are you aware that ...” often. Sometimes we say “have you noticed that ... ?” to express similar thoughts, and this indicates a close connection between consciousness (awareness) and attention (noticing), which we will come back to later in this chapter. Ned Block, one of the key figures in this area, provides a useful characterization of (...) what he calls “phenomenal consciousness.” For him, phenomenal consciousness is experience. Experience covers perceptions, e.g., when we see, hear, touch, smell, and taste, we typically have experiences, such as seeing colors and smelling odors. It also covers bodily awareness, e.g., we typically have experiences of our own bodily temperature and positions of limbs. Consciousness is primarily about this experiential aspect of our mental lives. (shrink)

In this thesis, I use a close reading of the silent films of Charlie Chaplin to examine a question of listening posed by Jean-Luc Nancy, “Is listening something of which philosophy is capable” (Nancy 2007:1)? Drawing on the work of Nancy, Jacques Derrida and Gayatri Spivak, I consider a claim that philosophy has failed to address the topic of listening because a logocentric tradition claims speech as primary. In response to Derrida’s deconstruction of logocentrism, Nancy complicates the problem of listening (...) by distinguishing between l’écoute and l’entente. L’écoute is an attending to and answering the demand of the other and l’entente is an understanding directed inward toward a subject. Nancy could deconstruct an undervalued position of l’écoute, making listening essential to speech. I argue, Nancy rather asks what kind of listening philosophy is capable of. To examine this question, I focus on the peculiarly dialogical figure derived from Chaplin that communicates meaning without using speech. This discussion illustrates how Chaplin, in the role of a silent figure, listens to himself (il s’écoute) as other. Chaplin’s listening is Nancean resonance, a movement in which a subject refers back to itself as another subject, in constant motion of spatial and temporal non-presence. For Nancy, listening is a self’s relationship to itself, but without immediate self-presence. Moving in resonance, Chaplin makes the subject as other as he refers back to himself as other. I argue that Chaplin, through silent dialogue with himself by way of the other, makes his listening listened to. Chaplin refused to make his character speak because he believed speech would change the way in which his work would be listened to. In this way, Chaplin makes people laugh by making himself understood (se fait entendre) as he makes himself listened to (se fait écouter). In answer to Nancy’s question, I conclude philosophy is capable of meeting the demand of listening as both l’entente and l’écoute when it listens as Chaplin listens. (shrink)

In this paper I consider the possibility of a kind of a priori cognition that serves the purposes of metaphysics, given that metaphysics involves the search for modal knowledge. Necessary or, better, modal knowledge is a priori; so metaphysical knowledge is likewise a priori. Here I argue that intuition is the route to modal knowledge in metaphysics, and I insist that conceivability or knowledge of conceptual truths does not lead towards the modal realm of metaphysics.

This article presents a novel reading of Descartes’s critique of the traditional syllogistic. The reading differs from those previously presented by scholars who regard Descartes’s critique as a version of a well-known argument: that syllogisms are circular or non-ampliative and thus trivial. It is argued that Descartes did not see syllogisms as defective in themselves. For him the problem was rather that anyone considering a valid and informative syllogism must already know, by an intuition wholly independent of the syllogism, that (...) the conclusion follows from the premises. Moreover, without such an intuition the syllogistic on its own is incapable of determining whether the consequence truly holds. Thus the syllogistic is useless unless accompanied by an intuition that renders it otiose. This reading of Descartes’s view is supported and explained by examples drawn from Descartes’s writing and from the Port-Royal Logic—one of the first attempts to develop a logical system on Cartesian principles.

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)

Much ado has been made regarding Descartes's understanding of the creation of what he called the "eternal truths" because he described them, paradoxically, as both the free creations of God, and necessary. While there are many varying interpretations of Cartesian modality, the issue has heretofore been treated in a vacuum, as a niche issue having little import beyond being an interesting puzzle for Descartes Scholars. I argue that this treatment is misguided, and that in order to properly understand Cartesian philosophy (...) at all, one must properly understand Descartes's theory of modality. This, however, is no small feat; in order to understand Descartes's seemingly peculiar view on modality, one must first make sense of what Descartes understood the nature of God to be. One reason for this, I argue, is the systematic nature of Cartesian philosophy; indeed when dealing with a dense inter-connection of philosophical issues, one must move from what is more known in itself to what is more known to us, and not the other way around. I argue that in the literature on Cartesian modality, insufficient attention has been paid to the influence of the French School of Spirituality on the Cartesian notion of the divine. I argue that this influence pushed Descartes to criticize traditional attempts to split the horns of Plato's Euthyphro dilemma as violating a proper understanding of the doctrine of divine simplicity. Descartes's commitment to a radical form of the doctrine of divine simplicity leads him to a version of divine voluntarism wherein all `things' depend on God for their existence, and God cannot have had antecedent reason to prefer the creation of anything over anything else. There is little doubt that Descartes embraced the voluntarist horn of the Euthyphro dilemma, but just what that means for Cartesian modality and philosophy generally remains a contentious issue. I argue that Descartes is best read as what I call an `agnostic quietist' regarding God given textual, historical, and systematic considerations. One virtue of an agnostic quietist reading is that I am able to square the passages where Descartes discusses the inconceivability of God's power with the conclusions reached regarding God's non-deceiving nature in the Meditations and elsewhere. Further virtues that I explore are the effects that a quietist reading has on the Cartesian scientific programme, the infamous mind-body problem, Descartes's seemingly inconsistent view regarding human free-will and Descartes's refusal to engage in "theology." Traditionally, Cartesian epistemology has been understood to be a purely a priori undertaking, which succumbs to deep and insurmountable problems. One of the greatest problems facing the Cartesian was the move from the mind to the world. Simon Blackburn, for example, says of the Cartesian epistemological project in the Meditations that Descartes "has put himself on a desert island from which there is no escape." This view is echoed by, and even motivates some of the contemporary views concerning Cartesian modality. I argue, however, that a proper understanding of the Cartesian doctrine of clear and distinct ideas circumvents this famous problem. By highlighting the proper understanding and application of the doctrine of clear and distinct ideas, I show that such ideas not only guarantee the existence of an external truth-maker, but also that such ideas do not do much more than show that there is a truth-maker. I argue that in instances of clear and distinct perception, the truth of the idea is normatively certain, but what makes it true is yet to be established. In this way, clear and distinct ideas are both powerful, in terms of guaranteeing truth, and relatively unhelpful, in that further work is required in order to determine to what the ideas conform. I argue that this is the case not only for actual truths, but for some clearly intuited truths about possibility. As an illustration of my overall thesis, I address the Cartesian argument for the separability of mind and body, and entertain the various interpretations of Descartes's view of human freedom. I argue that in order to understand Cartesian views on either of these issues, one must first make sense of his modal commitments. In both of these cases Descartes claims that finite minds can know that something is possible, even though what makes it possible is well beyond what they can understand. (shrink)
