In the Fifth Meditation, Descartes makes a remarkable claim about the ontological status of geometrical figures. He asserts that an object such as a triangle has a 'true and immutable nature' that does not depend on the mind, yet has being even if there are no triangles existing in the world. This statement has led many commentators to assume that Descartes is a Platonist regarding essences and in the philosophy of mathematics. One problem with this seemingly natural reading is that (...) it contradicts the conceptualist account of universals that one finds in the Principles of Philosophy and elsewhere. In this paper, I offer a novel interpretation of the notion of a true and immutable nature which reconciles the Fifth Meditation with the conceptualism of Descartes' other work. Specifically, I argue that Descartes takes natures to be innate ideas considered in terms of their so-called 'objective being'. (shrink)

The Cambridge Descartes Lexicon is the definitive reference source on René Descartes, 'the father of modern philosophy' and arguably among the most important philosophers of all time. Examining the full range of Descartes' achievements and legacy, it includes 256 in-depth entries that explain key concepts relating to his thought. Cumulatively they uncover interpretative disputes, trace his influences, and explain how his work was received by critics and developed by followers. There are entries on topics such as certainty, cogito ergo sum, (...) doubt, dualism, free will, God, geometry, happiness, human being, knowledge, Meditations on First Philosophy, mind, passion, physics, and virtue, which are written by the largest and most distinguished team of Cartesian scholars ever assembled for a collaborative research project - 91 contributors from 12 countries.

Fourteen newly commissioned essays trace the historical development of the distinction between primary and secondary qualities, which lies at the intersection of issues in metaphysics, epistemology, and philosophy of perception. 'Primary and Secondary Qualities' focuses on the age of the Scientific Revolution, the 'locus classicus' of the distinction, but begins with chapters on ancient Greek and Scholastic accounts of qualities in an effort to identify its origins. The remainder of the volume is devoted to philosophical reflections on qualities from the (...) seventeenth century to the present day. Virtualliy every major figure is represented from Gassendi to Kant, and special attention is paid to Locke, Descartes, and Hume. The essays collected here cover a wide range of topics, including the foundation for the distinction, the question of whether it is lmetaphysical or merely epistemic, the status of secondary qualities, the nature of sensoriy representation, the relation between philosophy and science, the status of dispositions, and the semantics of sensible-quality terms"--Publisher's description, p.

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.

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Philosophy 43.1 (2005) 55-81 [Access article in PDF] Self-Knowledge in Descartes and Malebranche Lawrence Nolan John Whipple 1. Introduction Descartes's notorious claim that mind is better known than body has been the target of repeated criticisms, but none appears more challenging than that of his intellectual heir Nicolas Malebranche.1 Whereas other critics—especially twentieth-century philosophers eager to use Descartes as their whipping boy—have (...) often been uncharitable, Malebranche accepts many of the fundamental Cartesian doctrines, including mind-body dualism. But he argues that Descartes's position on knowledge of the mind is internally inconsistent. Malebranche agrees with Descartes that the existence of the mind is better known than that of body, but he vehemently denies that the nature of the mind is better known. This denial is based on his view that we lack a clear idea of the mind.2 [End Page 55]Malebranche's polemic has attracted much attention in recent scholarship.3 The growing consensus among commentators is that Malebranche develops a devastating internal critique of Descartes's theory of the mind. For example, Nicholas Jolley writes: "In his case for his negative thesis [concerning knowledge of the mind] Malebranche mounted a powerful, even annihilating, critique of Descartes. This critique embodies the remarkable insight that there is a serious muddle at the heart of Descartes's whole theory of knowledge."4 In a book-length defense of Malebranche's critique, Tad Schmaltz also emphasizes its internal character: "the interpretation here of Malebranche's theory presents it as fundamentally Cartesian, and thereby serves to reinforce his own view that he has provided an authoritative interpretation of the account of mind in the writings of Descartes and other Cartesians."5 Schmaltz also asserts: "Malebranche took his negative thesis concerning our knowledge of the soul to involve not so much a rejection of Cartesianism as an internal correction of it."6We think such remarks misstate the case. Indeed, we argue in this paper that Malebranche's polemic fails as an internal critique of Descartes's theory of the mind. Although we do not here aspire to defend Descartes's strong thesis—that mind is better known than body—we do think he can consistently maintain that we have a clear and distinct idea of the mind, and thus that our knowledge of the mind's nature is at least on a par with our knowledge of corporeal nature.7 While Malebranche's rhetoric would encourage us to think that the debate between him and his predecessor is being fought on common or neutral ground, the fact is that Malebranche often appeals to assumptions and aspects of his own theory of "Vision in God" that Descartes would reject. Once more, he interprets Descartes's theory of knowledge in ways that are misguided and sometimes even uncharitable. If Malebranche's critique succeeds at all, it succeeds only against a straw man—Malebranche's Descartes and not the historical figure.Ours is not the first effort to defend Descartes against this particular attack. When Malebranche first published his critique in Book Three of his first great work, The Search After Truth (1674),8 Descartes had been dead for over two decades, [End Page 56] but he was ably defended by the famous Cartesian Antoine Arnauld in On True and False Ideas (1683). In the ensuing debate Arnauld was clearly the superior dialectician, but while winning several tactical points, he appears not to fully appreciate the crux of Malebranche's argument, or at least that is the view of Jolley and Schmaltz.9 We have a somewhat higher opinion of Arnauld's side of the debate. Granted, some of his defenses are facile and can be easily dismissed; others however are quite compelling when properly developed. In at least one instance, we attempt to provide that development. At the same time we think it is a mistake to treat Arnauld as Descartes's surrogate or as if he had issued the final salvo from the camp of the orthodox Cartesians. Arnauld was a... (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.

Nicolas Malebranche holds that we see all things in the physical world by means of ideas in God (the doctrine of "vision in God"). In some writings he seems to posit ideas of particular bodies in God, but when pressed by critics he insists that there is only one general idea of extension, which he calls “intelligible extension.” But how can this general and “pure” idea represent particular sensible objects? I develop systematic solutions to this and two other putative difficulties (...) with Malebranche’s theory of sensory cognition by appealing to the notion of “seeing as” and to his doctrine that ideas in God have causal powers to affect the mind.

This chapter contains section titled: The Simplicity of Descarteś Proofs and the Relation between Them The Causal Argument The Ontological Argument.

This long and ambitious work offers a systematic interpretation of Cartesian metaphysics and epistemology from the perspective of Descartes’s so-called founding principle, cogito ergo sum. The book is organized around the three parts of this famous dictum, though its scope is much more encompassing. Part 1 offers a careful analysis of the “formal structure” of Cartesian thought, in an effort to identify what is distinctive about the cogito and to uncover how Descartes’s theory of mind makes this insight possible. Part (...) 2 addresses the notions of truth and certainty as they relate to the claim “I exist”. Part 3 tackles one of the most vexed interpretive questions relating to the cogito, namely, whether and in what sense “I exist” is inferred from “I think,” as the logical particle ergo would seem to suggest. The cogito principle, however, is only the lens through which Miles examines Descartes’s larger system. One attractive feature of the project is that he uses this principle to develop what he takes as a key to Descartes’s philosophy—the process of “analytical reflexion” by which knowledge that was previously only implicit is explicitly intuited. This interpretive key is then employed to unlock many of the other major Cartesian themes, including the method of doubt, clear and distinct perception, innate ideas, analytic and synthetic method, the infamous Circle, and the divine creation of the eternal truths. The result is a set of extremely scholarly readings of important texts and doctrines that, if not always convincing, is fresh, nuanced, and provocative. (shrink)

Reasoning about situations we take to be impossible is useful for a variety of theoretical purposes. Furthermore, using a device of impossible worlds when reasoning about the impossible is useful in the same sorts of ways that the device of possible worlds is useful when reasoning about the possible. This paper discusses some of the uses of impossible worlds and argues that commitment to them can and should be had without great metaphysical or logical cost. The paper then provides an (...) account of reasoning with impossible worlds, by treating such reasoning as reasoning employing counterpossible conditionals, and provides a semantics for the proposed treatment.

It is almost universally believed that some infinite regresses are vicious, and also almost universally believed that some are benign. In this paper I argue that regresses can be vicious for several different sorts of reasons. Furthermore, I claim that some intuitively vicious regresses do not suffer from any of the particular aetiologies that guarantee viciousness to regresses, but are nevertheless so on the basis of considerations of parsimony. The difference between some apparently benign and some apparently vicious regresses, then, (...) turns out to be a matter of a more general assessment of costs and benefits, making viciousness of regresses in some cases less of a local matter than is usually thought.

Departing from the sociological dual process model that divides thoughts into automatic and unconscious, or deliberate and conscious occurrences, this book draws on empirical cases to demonstrate the existence of 'automatic deliberation'. Through research into the ways in which people address difficult subjects, such as death and dying, paedophilia, and career decision-making, the author sheds light on a mode of thinking which is both habitual and effortful, displaying a combination of habituated understandings and conscious deliberation. Advancing a blended view of (...) cognition by which individuals draw on schemas and frames to think through complex topics, this volume will appeal to sociologists and psychologists with interests in cognition and the ways in which we make decisions.

Logic and Computation is concerned with techniques for formal theorem-proving, with particular reference to Cambridge LCF (Logic for Computable Functions). Cambridge LCF is a computer program for reasoning about computation. It combines methods of mathematical logic with domain theory, the basis of the denotational approach to specifying the meaning of statements in a programming language. This book consists of two parts. Part I outlines the mathematical preliminaries: elementary logic and domain theory. They are explained at an intuitive level, giving references (...) to more advanced reading. Part II provides enough detail to serve as a reference manual for Cambridge LCF. It will also be a useful guide for implementors of other programs based on the LCF approach. (shrink)

In the Canon of the Critique of Pure Reason, Kant endorses both a Moral Belief in God as well as what he there calls Doctrinal Belief. The former mode of belief is well known and can be found throughout the Kantian Corpus. The latter, however, is far more obscure and thus far has not been carefully studied. Doctrinal Belief only appears explicitly in the Canon, but is related to a number of issues in the Transcendental Dialectic as well as the (...) Critique of Judgment. This paper will provide an account of the Doctrinal Belief in God and consider its compatibility with Kant’s other discussions of the projected ground of the principle of purposiveness. (shrink)

Possible worlds have found many applications in contemporary philosophy: from theories of possibility and necessity, to accounts of conditionals, to theories of mental and linguistic content, to understanding supervenience relationships, to theories of properties and propositions, among many other applications. Almost as soon as possible worlds started to be used in formal theories in logic, philosophy of language, philosophy of mind, metaphysics, and elsewhere, theorists started to wonder whether impossible worlds should be postulated as well. In many applications, possible worlds (...) face limitations that can be dealt with through postulating impossible worlds as well. This chapter examines some of the uses of impossible worlds, and philosophical challenges theories of impossible worlds face. (shrink)

After considering Buber’s and Levinas’s critiques of Heidegger and of each other, I propose that we should acknowledge authenticity, “essential relations” of love and friendship, and holiness as aspects of a good life, though they pull in different directions. We should resist the temptation to take sides in a battle between different approaches to the complex nature of our social being.

In lieu of an abstract, here is a brief excerpt of the content:Christ's Human Nature and the Cry from the Cross:St. Thomas Aquinas on Psalm 22:2Philip Nolan O.P.Christ's cry from the Cross quoting Psalm 22 (Mark 15:34; Matt 27:46) has become a central focus for contemporary Christological debates.1 A number of modern thinkers have read this verse as expressing in Christ an experience of dereliction incompatible with traditional positions concerning divine impassibility Christ's beatific knowledge, and Trinitarian relations.2 Thomas Joseph (...) White has recently offered an insightful Thomistic critique of these interpretations: [End Page 1219]The final cry of Christ on the cross cannot be interpreted as a cry of either despair or of spiritual separation from God. By contrast, it must be understood theologically as a prayer of desire related to Christ's abandonment to the Father and his hope to introduce humanity into the eschatological gift of redemption.3In his work, White is concerned to engage with modern Christological themes using principles derived from the Thomistic tradition. For this reason, he articulates a rather original alternative to modern theologies of dereliction—especially those marked by divine kenoticism and Luther's theology of the Cross. In offering a view inspired by Thomistic principles, White presents his own creative retrieval of Aquinas's ideas concerning the cry from the Cross.At times, however, White's argument leaves somewhat obscure the literal meaning of the words of that cry: "My God, my God, why have you abandoned me?"4 For example, in pushing back against radical interpretations [End Page 1220] of dereliction, he shifts the language of "abandonment" from God's abandonment of Christ to Christ's abandonment to the Father. My argument in this article is that the textual commentaries on Psalm 225 by Augustine and Aquinas—material that White does not consider specifically—can provide an alternate and somewhat complementary Thomistic approach to the one White proposes, and one more soundly based on Aquinas's texts themselves.6 Christ's cry is a quote from this psalm, and Aquinas's commentary on Ps 22:27 develops the Augustinian interpretation of this verse in order to give greater emphasis to Christ's human nature. This emphasis helps to explain, in a classical way, what it can mean that Christ is abandoned. Thus, Aquinas's exegesis bolsters the orthodox response to contemporary revisionist theologians by providing a clear literal understanding of this contested biblical passage without applying an experience of damnation to Christ or denying classical positions concerning divine impassibility, Christ's beatific knowledge, and the nature of Trinitarian relations.To make this argument, I will first look at the rich tradition of reflection on the Christological meaning of the Psalms, and Psalm 22 in particular, inherited by Thomas. This tradition includes a series of psalm commentaries, conciliar documents, and a variety of other theological works. In this tradition, I argue, we see two primary interpretative approaches. The first is what I will call the Augustinian approach, which insists that Christ is speaking on the Cross for sinners and in the voice of sinners. The second interpretation places more weight on Christ's own voice and insists that he is speaking in a real way for himself—Christ in some way truly is abandoned by God. These interpretations need not and should not be read as contradictory. In fact, all the authorities I examine insist on the first approach. Differences emerge, however, in how they coordinate the latter interpretation with the former. I will discuss Thomas's synthesis of these interpretations, a synthesis that he grounds in the reality of Christ's human nature. Finally, I will suggest [End Page 1221] how a close reading of Thomas's mature treatment of Ps 22:2 supplements contemporary Thomist responses to modern Christological concerns and misguided interpretations of Christ's cry on the Cross.Thomas's Sources for Reading Psalm 22:2Thomas's primary source for understanding Ps 22:2 is Scripture itself Both Mark and Matthew report that Christ spoke the words of this psalm from the Cross, a fact which necessitates for Thomas a Christological interpretation of the psalm.8 Augustine links Ps 22:2 with passages in...

Soon after the book's publication in 1982, artist David Hockney read Lawrence Weschler's _Seeing Is Forgetting the Name of the Thing One Sees: A Life of Contemporary Artist Robert Irwin _and invited Weschler to his studio to discuss it, initiating a series of engrossing dialogues, gathered here for the first time. Weschler chronicles Hockney's protean production and speculations, including his scenic designs for opera, his homemade xerographic prints, his exploration of physics in relation to Chinese landscape painting, his investigations (...) into optical devices, his taking up of watercolor—and then his spectacular return to oil painting, around 2005, with a series of landscapes of the East Yorkshire countryside of his youth. These conversations provide an astonishing record of what has been Hockney's grand endeavor, nothing less than an exploration of "the structure of seeing" itself. (shrink)
