In two rarely discussed passages – from unpublished notes on the Principles of Philosophy and a 1647 letter to Chanut – Descartes argues that the question of the infinite extension of space is importantly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)

This volume is the first annotated translation in any language of the entire text of the Summulae de dialectica, by the Parisian master of arts John Buridan (1300-1358). One of the most influential works in the history of late medieval philosophy, the Summulae is Buridan's systematic exposition of his nominalist philosophy of logic. Buridan's doctrine spread rapidly and for some two hundred years was dominant at many European universities. His work is of increasing interest today not only to historians of (...) medieval philosophy but also to modern philosophers, several of whom find in Buridan's ideas important clues to problems of contemporary philosophy. Gyula Klima provides a substantial introduction to Buridan's life and work and discusses his place in the history of logic. Through extensive notes Klima assists philosopher and medievalist alike to read Buridan with understanding and insight. Those with a philosophical interest in the relations among the structures of language, thought, and reality will find much to ponder in the Summulae. (shrink)

This handsome new edition of Stanley Cavell's landmark text, first published 20 years ago, provides a new preface that discusses the reception and influence of his work, which occupies a unique niche between philosophy and literary studies.

Descartes intended to revolutionize seventeenth-century philosophy and science. But first he had to persuade his contemporaries of the truth of his ideas. Of all his publications, Meditations on First Philosophy is methodologically the most ingenuous. Its goal is to provoke readers, even recalcitrant ones, to discover the principles of “first philosophy.” The means to its goal is a reconfiguration of traditional methodological strategies. The aim of this chapter is to display the methodological strategy of the Meditations. The text’s method is (...) more subtle and more philosophically significant than has generally been appreciated. Descartes’ most famous work is best understood as a response to four somewhat separate philosophical concerns extant in the seventeenth century. Section 1 describes these. Section 2 discusses how Descartes uses and transforms them. A clearer sense of the Meditations’ methodological strategy provides a better understanding of exactly how Descartes intended to revolutionize seventeenth-century thought. (shrink)

Work on Scotus's moral psychology and action theory has been concerned almost exclusively with questions about the relationship between will and intellect and in particular about the freedom of the will itself. In this essay I broaden the scope of inquiry. For I contend that Scotus's views in moral psychology are best understood against the background of a long tradition of metaethical reflection on the relationship between being and goodness. In the first section of this essay, therefore, I sketch the (...) main lines of that tradition in medieval thinking and examine the novel and sometimes daring ways in which Scotus appropriated them. In the sections that follow I elaborate on three areas of Scotus's action theory, very broadly conceived, in which his modifications of the medieval metaethical tradition can be seen bearing philosophical fruit. Thus, in the second section I examine his account of the goodness of moral acts, in the third his understanding of the passive dispositions of both sensitive appetite and will, and in the fourth his account of the active power of will.

Latest version of my SEP entry on ontological arguments, which first appeared in 1996. General discussion of ontological arguments. Includes a brief historical overview, a taxonomy of different kinds of ontological arguments, a brief survey of objections to the different kinds of ontological arguments identified in the taxonomy, and more extended discussions of Anselm's ontological argument (Proslogion 2), Godel's ontological argument, and Plantinga's ontological argument.

We argue that Descartes’s theistic proofs in the ’Meditations’ are much simpler and straightforward than they are traditionally taken to be. In particular, we show how the causal argument of the "Third Meditation" depends on the intuitively innocent principle that nothing comes from nothing, and not on the more controversial principle that the objective reality of an idea must have a cause with at least as much formal reality. We also demonstrate that the so-called ontological "argument" of the "Fifth Meditation" (...) is best understood not as a formal proof but as an axiom, revealed as self-evident by analytic meditation.

Descartes revolutionized our conception of the mind by identifying consciousness as the mark of the mental: all and only thoughts are conscious. Today the idea that all thoughts are conscious seems obviously wrong. Worse, however, Descartes himself seems to posit a whole host of unconscious thoughts. Something is not as it seems. Either Descartes is remarkably inconsistent, or his claim that all thought is conscious is more nuanced than it appears. In this paper I argue that while Descartes was indeed (...) unwavering in his commitment to the conscious mark, he had the resources to distinguish different types and degrees of consciousness that make for a richer cognitive psychology than he is typically credited with.

My main thesis in this article is that Descartes' ethics should be understood as involving a distinction between happiness and well-being. The distinction I have in mind is never clearly stated or articulated by Descartes himself, but I argue that we nevertheless have good reason to embrace it as an important component in a charitable reconstruction of his ethical thought. In section I, I present Descartes' account of happiness and of how he thinks happiness can (and cannot) be acquired. Then, (...) in section II, I introduce and develop the distinction between happiness and well-being. I do this via a discussion of a difficult passage in one of Descartes' letters to Elisabeth, where he may seem first to grant and then immediately to reject the view that people's happiness can vary in degree depending on the possession of goods or perfections that are outside their power to control. I believe my proposed distinction can help us make good sense of this passage. In the last two sections (III and IV), I then offer some further grounds or reasons for why the proposed distinction should be ascribed to Descartes. (shrink)

It is the object of the present paper to undertake a logical inquiry into one particular kind of evidence that has been taken to be capable of furnishing a rational warrant for doubt. The line of thought at issue finds its classic expression in the case for doubt argued by Descartes in the first of his Meditations on First Philosophy. Descartes' argument is as follows.

SOME MODERN THOMISTS claiming to follow the lead of Thomas Aquinas, hold that the objects of the types of mathematics known in the thirteenth century, such as the arithmetic of whole numbers and Euclidean geometry, are real entities. In scholastic terms they are not beings of reason but real beings. In his once-popular scholastic manual, Elementa Philosophiae Aristotelico-Thomisticae, Joseph Gredt maintains that, according to Aristotle and Thomas Aquinas, the object of mathematics is real quantity, either discrete quantity in arithmetic or (...) continuous quantity in geometry. The mathematician considers the essence of quantity in abstraction from its relation to real existence in bodily substance. "When quantity is considered in this way," he writes, "it is not a being of reason but a real being. Nevertheless it is so abstractly considered that it leaves out of account both real and conceptual existence." Recent mathematicians, Gredt continues, extend their speculation to fictitious quantity, which has conceptual but not real being; for example, the fourth dimension, which by its essence positively excludes a relation to real existence. According to Gredt this is a special, transcendental mathematics essentially distinct from "real mathematics," and belonging to it only by reduction. (shrink)

Contemporary discussions typically give somewhat sort shrift to the theory of judgment Descartes advances in the Fourth Meditation.' One reason for this relative neglect is presumably the prima facie implausibility of the theory. It sounds odd to say that, in believing something, one's mental affirmation is an act of free will, on a par with freely deciding what to do. In addition, Descartes advances the theory as a way to explain the possibility of human error, which doubtless strikes many as (...) a rather esoteric undertaking. The need to explain error, moreover, arises because of the divine guarantee, and epistemic theodicy is a project unlikely to interest most contemporary readers. And because the theory of judgment postulates two mental.. (shrink)

The Principle of Sufficient Reason is a powerful and controversial philosophical principle stipulating that everything must have a reason or cause. This simple demand for thoroughgoing intelligibility yields some of the boldest and most challenging theses in the history of metaphysics and epistemology. In this entry we begin with explaining the Principle, and then turn to the history of the debates around it. A section on recent discussions of the Principle will be added in the near future.

German description: Descartes' Meditationen von 1641 haben bis heute die philosophische Reflexion immer wieder herausgefordert. In diesem Werk geht er von einer Haltung radikalen Zweifels aus, macht dann aber geltend, dass selbst ein ausserster Skeptizismus nicht die fundamentale Wahrheit, dass ich existiere, in Frage stellen kann: ego sum, ego existo. Ausgehend von dieser Gewissheit versucht Descartes, die Grundlagen einer neuen Wissenschaft zu legen. Ursprunglich auf Lateinisch verfasst, wurden die Meditationes 1647 ins Franzosische ubersetzt. Diese Ubersetzung wurde von Descartes selbst durchgesehen (...) und bearbeitet und unterscheidet sich in vielen Nuancen vom lateinischen Original. Diese Ausgabe ist die einzige, die neben der neuen Ubersetzung ins Deutsche den lateinischen Text wie auch die franzosische Version bietet. Erganzt wird sie durch einen umfangreichen Kommentar. Sie eignet sich damit besonders als Arbeitsbuch fur Studenten. (shrink)

Descartes affords several notions of consciousness as he explains the characteristics of the diverse features of human thought from infancy to adulthood and from dreaming to attentive wakefulness. The paper argues that Descartes has a rich and coherent view of conscious mentality from rudimentary consciousness through reflexive consciousness to consciousness achieved by deliberate, attentive reflection.

The Renaissance has long been recognized as a brilliant moment in the development of Western civilization. Little attention has been devoted, however, to the distinct contribution of philosophy to Renaissance culture. This volume introduces the reader to the philosophy written, read, taught, and debated during the period traditionally credited with the "revival of learning." Beginning with original sources still largely inaccessible to most readers, and drawing on a wide range of secondary studies, the author examines the relation of Renaissance philosophy (...) to humanism and the universities, the impact of rediscovered ancient sources, the recovery of Plato and the Neoplatonists, and the evolving ascendancy of Aristotle. Renaissance Philosophy also explores the original contributions of major figures including Bruni, Valla, Ficino, Pico della Mirandola, Pomponazzi, Machiavelli, More, Vitoria, Montaigne, Bruno, and Camapanella.

Stoicism was one of the new philosophical movements of the Hellenistic period. The name derives from the porch (stoa poikilê) in the Agora at Athens decorated with mural paintings, where the members of the school congregated, and their lectures were held. Unlike ‘epicurean,’ the sense of the English adjective ‘stoical’ is not utterly misleading with regard to its philosophical origins. The Stoics did, in fact, hold that emotions like fear or envy (or impassioned sexual attachments, or passionate love of anything (...) whatsoever) either were, or arose from, false judgements and that the sage—a person who had attained moral and intellectual perfection—would not undergo them. The later Stoics of Roman Imperial times, Seneca and Epictetus, emphasise the doctrines (already central to the early Stoics' teachings) that the sage is utterly immune to misfortune and that virtue is sufficient for happiness. Our phrase ‘stoic calm’ perhaps encapsulates the general drift of these claims. It does not, however, hint at the even more radical ethical views which the Stoics defended, e.g. that only the sage is free while all others are slaves, or that all those who are morally vicious are equally so. Though it seems clear that some Stoics took a kind of perverse joy in advocating views which seem so at odds with common sense, they did not do so simply to shock. Stoic ethics achieves a certain plausibility within the context of their physical theory and psychology, and within the framework of Greek ethical theory as that was handed down to them from Plato and Aristotle. It seems that they were well aware of the mutually interdependent nature of their philosophical views, likening philosophy itself to a living animal in which logic is bones and sinews; ethics and physics, the flesh and the soul respectively (another version reverses this assignment, making ethics the..

This paper defends an interpretation of Descartes according to which he sees us as having normative (and not merely psychological) certainty of all clear and distinct ideas during the period in which they are apprehended clearly and distinctly. However, on this view, a retrospective doubt about clear and distinct ideas is possible. This interpretation allows Descartes to avoid the Cartesian Circle in an effective way and also shows that Descartes is surprisingly, in some respects, an epistemological externalist. The paper goes (...) on to defend this interpretation against some powerful philosophical objections by Margaret Wilson and others by showing how Descartes' doctrine of the creation of the eternal truths can be brought in to support his epistemology. This doctrine and other analogous positions in Descartes can also reveal that Descartes, again surprisingly, takes important steps toward doing epistemology without direct appeal to God and God's veracity.

_Material Falsity and Error in Descartes’s Meditations _approaches Descartes’s Meditations as an intellectual journey, wherein Descartes’s views develop and change as he makes new discoveries about self, God and matter. The first book to focus closely on Descartes’s notion of material falsity, it shows how Descartes’s account of material falsity – and correspondingly his account of crucial notions such as truth, falsehood and error – evolves according to the epistemic advances in the Meditations. It also offers important new insights on (...) the crucial role of Descartes’s Third Meditation discussion of material falsity in advancing many subsequent arguments in the Meditations. This book is essential reading for those working on Descartes and early modern philosophy. It presents an independent reading on issues of perennial interest, such as Descartes’s views on error, truth and falsehood. It also makes important contributions to topics that have been the focus of much recent scholarship, such as Descartes’s ethics and his theodicy. Those working on the interface between medieval and modern philosophy will find the discussions on Descartes’s debt to predecessors like Suárez and Augustine invaluable. (shrink)

Perhaps the most famous proposition in the history of philosophy is Descartes' cogito 'I think, therefore I am'. Husain Sarkar claims in this provocative interpretation of Descartes that the ancient tradition of reading the cogito as an argument is mistaken. It should, he says, be read as an intuition. Through this interpretative lens, the author reconsiders key Cartesian topics: the ideal inquirer, the role of clear and distinct ideas, the relation of these to the will, memory, the nature of intuition (...) and deduction, the nature, content and elusiveness of 'I', and the tenability of the doctrine of the creation of eternal truths. Finally, the book demonstrates how Descartes' attempt to prove the existence of God is foiled by a new Cartesian Circle. (shrink)

In a number a passages Descartes appears to insist that "I am, I exist" and its variants are wholly indubitable. These passages present an intractable problem of interpretation in the face of passages in which Descartes allows that any result is dubitable, "I am, I exist" included. Here I pull together a number of elements of Descartes' system to show how all of these passages hang together. If my analysis is correct, it tells us something about the perspective that Descartes (...) himself thinks we should take in reading the "Meditations". (shrink)

For Descartes, consciousness is closely connected to the intellective perception of thought. This paper argues that the prevalent interpretations of Descartes's account of consciousness in terms of higher-order perception and self-representation fail. These interpretations mistakenly assume that Cartesian consciousness possesses the same theoretical structure in all cases. It is shown by a close analysis of relevant passages that for Descartes the consciousness of perceptions and the consciousness of volitions have different theoretical structures. From this analysis a more adequate picture of (...) Cartesian consciousness is developed and, finally, compared with a recent reconstruction provided by Vili Lähteenmäki. (shrink)

The first doctrine Peckham mentions as being under attack is of undoubtedly the TDI, according to which human beings are illuminated by "the unchangeable light" so as to attain the "eternal rules." This language of light and illumination is of course most closely associated with Augustine, but it permeates the entire Christian medieval tradition. Until Aquinas's time the TDI had played a prominent role in all the most influential medieval theories of knowledge, including those of Anselm, Albert the Great, Roger (...) Bacon, and, especially, Bonaventure. However, by the beginning of the fourteenth century the theory had fallen out of fashion. Indeed, the three best philosophers of the scholastic period--Aquinas, John Duns Scotus, and William Ockham--would all reject the theory in its standard form. Even by 1285 supporters of the TDI such as Peckham were evidently feeling rather defensive. It seems entirely plausible to attribute this attitude, in large part, to the influence of Aquinas's views on human knowledge. (shrink)

One question that has created controversy among interpreters is just how much is in doubt at the end of the Dream Argument in Meditation I. I argue that there is doubt about the existence of composite bodies not yet about the existence of a physical world. I also caution against using later parts of the Meditations to interpret the First Meditation on account of the order of reasons in this work. I connect the Omnipotent God argument to Descartes's views about (...) innate ideas and analyze the First Meditation in relation to Descartes's anti-aristotelian purposes. (shrink)

The Renaissance sceptic and medical doctor Francisco Sanchez has been rather unduly neglected in scholarly work on Renaissance scepticism. In this paper I discuss his scepticism against the background of the ancient distinction between Academic and Pyrrhonian scepticism. I argue that Sanchez was a Pyrrhonist rather than, as has been claimed in recent years, a mitigated Academic sceptic. In keeping with this I shall also try to show that Sanchez was crucially influenced by the ancient medical school of empiricism, a (...) school closely allied with Pyrrhonism. (shrink)

A main epistemic problematic, found already in Aristotle’s Posterior Analytics, presents a threefold choice on how a belief may be justified: either through infinitely regressive reasoning, or through circular reasoning, or through reasoning resting ultimately on some foundation. Aristotle himself apparently takes the foundationalist option when he argues that rational intuition is a foundational source of scientific knowledge. The five modes of Agrippa, which pertain to knowledge generally, again pose the same problematic, the “Pyrrhonian” problematic. And here Galen and the (...) Stoics also opt for foundations. Sections I and II below explore that foundationalist option. Section III draws some lessons. And Section IV uses these to interpret Descartes. I argue that Descartes shows us the way beyond the Pyrrhonian problematic, although his way is not that traditionally attributed to him. On these basic issues of epistemology, Descartes is no Cartesian. (shrink)

In two recent papers, Michael Della Rocca accuses Descartes of reasoning circularly in the Fourth Meditation. This alleged new circle is distinct from, and more vicious than, the traditional Cartesian Circle arising in the Third Meditation. We explain Della Rocca’s reasons for this accusation, showing that his argument is invalid.

Artikkelissa otan kantaa niin sanottuun voluntarismikiistaan Descartesin tahdon käsitykseen ja arvostelmateoriaan liittyen kannattaen epäsuoraa voluntarismia. Käsittelen erityisesti kysymystä voiko tahdolla Descartesin mukaan olla suora kontrolli ihmisen arvostelmasta pidättäytymiseen? Pitkään vallassa olleen tulkintasuuntauksen mukaan Descartesin käsityksessä tahdolla on kyky vaikuttaa doksastisiin tiloihin suoraan, pelkällä tahdon aktilla. Tätä kutsutaan suoraksi voluntarismiksi ja se tarkoittaa lyhyesti sanottuna sitä, että meillä on kyky hyväksyä, olla hyväksymättä sekä pidättäytyä arvostelemasta täysin tahdonvaraisesti. Tässä tekstissä kannatan kuitenkin epäsuoraa voluntarismia: tahto kykenee vaikuttamaan doksastiseen tilaan epäsuorasti vaikuttamalla uskomuksen (...) muodostamisen kannalta olennaisiin toimintoihin, erityisesti vahvoihin perusteisiin keskittymiseen. Argumentoin epäsuoran voluntarismin puolesta seuraavin tavoin: 1) Kohdat, joiden katsotaan puoltavan suoraa voluntarismia, voidaan yhtä lailla tulkita puoltamaan myös epäsuoraa voluntarismia, 2) Epäsuora voluntarismi on sekä filosofisesti että psykologisesti uskottavampi tulkinta siitä, kuinka ihminen arvostelmia muodostaa, ja 3) Epäsuora negatiivinen voluntarismi on koherentimpi ja ristiriidattomampi tulkinta epäilyn metodin käytöstä (siis yleisestä arvostelmasta pidättäytymisestä) Ensimmäisessä mietiskelyssä.

Scepticism is a subject which has preoccupied philosophers for two thousand years. This book presents an historical perspective on scepticism by considering contrasting views, such as those of Sextus Empiricus, Descartes and Hume, on why scepticism is important. With its historical perspective and analysis of contemporary discussions, _Scepticism_ provides a broad focus on the subject, differing from other discussions of the topic in the importance it attaches to scepticism both in Greek thought and in pre-twentieth century views generally.
