Leibniz and Kant were the most important figures in German philosophy from the late 17th to the early 19th century. This volume examines the relationships between their philosophies, illuminating fundamental questions of metaphysics, epistemology, and philosophical theology, and assessing Kant's understanding of his philosophical predecessor.

This essay examines arguments offered in support of the Principle of Sufficient Reason (PSR) by Leibniz and his followers as well as Hume's critique of the PSR. It is shown that Leibniz has a defensible argument for the PSR, whereas the arguments of his self-proclaimed followers are weak. Thus, Hume's challenge is met by Leibniz, by Wolff and Baumgarten not so much.

Gottfried Wilhelm Leibniz (1646–1716) was one of the great thinkers of the seventeenth and eighteenth centuries and is known as the last “universal genius”. He made deep and important contributions to the fields of metaphysics, epistemology, logic, philosophy of religion, as well as mathematics, physics, geology, jurisprudence, and history. Even the eighteenth century French atheist and materialist Denis Diderot, whose views could not have stood in greater opposition to those of Leibniz, could not help being awed by his achievement, writing (...) in his Encyclopedia, “Perhaps never has a man read as much, studied as much, meditated more, and written more than Leibniz… What he has composed on the world, God, nature, and the soul is of the most sublime eloquence. If his ideas had been expressed with the flair of Plato, the philosopher of Leipzig would cede nothing to the philosopher of Athens.” (Vol. 9, p. 379) Indeed, Diderot's mood was almost despairing in a remark from another piece, which also has a great deal of truth in it: “When one compares the talents one has with those of a Leibniz, one is tempted to throw away one's books and go die quietly in the dark of some forgotten corner.” More than a century later, Gottlob Frege, who fortunately did not cast his books away in despair, expressed similar admiration, declaring that “in his writings, Leibniz threw out such a profusion of seeds of ideas that in this respect he is virtually in a class of his own.” (“Boole's logical Calculus and the Concept script” in Posthumous Writings , p. 9) The aim of this entry is primarily to introduce Leibniz's life and summarize and explicate his views in the realms of metaphysics, epistemology, philosophical theology, and natural philosophy.

In the main article on Leibniz, it was claimed that Leibniz's philosophy can be seen as a reaction to the Cartesian theory of corporeal substance and the necessitarianism of Spinoza and Hobbes. This entry will address this second aspect of his philosophy. In the course of his writings, Leibniz developed an approach to questions of modality—necessity, possibility, contingency—that not only served an important function within his general metaphysics, epistemology, and philosophical theology but also has continuing interest today. Indeed, it has..

That Leibniz finds the philosophy of Spinoza horrifyingly wrong is obvious to anyone who reads Leibniz’s work; that Leibniz finds Spinozism so seductive that his own system is in danger of collapsing into it is less obvious but, I believe, equally true. The difference here is not so much between an exoteric and an esoteric philosophy suggested by Russell2 but between a thorough-going rationalism on the part of Spinoza and Leibniz’s “mitigated rationalism” – mitigated by the exigencies of his orthodox (...) Christianity. In other words, it is Leibniz’s traditional view of the nature of God and his creatures that leads him to abhor Spinoza’s vision, while his own commitment to a number of principles and ideas pushes him to rationalism. And if Kant is right that the mind naturally desires a system, then Leibniz ought to see the Spinozistic consequences of many of his philosophical principles. Of course, there is nothing new in saying that the God of Spinoza and the God of Leibniz are fundamentally different, but I believe that if we focus on Leibniz’s critique of Spinoza’s account of the nature of God and a constellation of related concepts, we can come to a deeper understanding of the thought of both philosophers.

In a short piece written most likely in the 1690s and given the title by Loemker of “On Wisdom,” Leibniz says the following: “...we see that happiness, pleasure, love, perfection, being, power, freedom, harmony, order, and beauty are all tied to each other, a truth which is rightly perceived by few.”1 Why is this? That is, why or how are these concepts tied to each other? And, why have so few understood this relation? Historians of philosophy are familiar with the (...) fact that both Spinoza and Leibniz place strong emphasis on the notion of power in giving their accounts of the human passions. But, while many scholars have explicated the relation between power and the passions (especially in Spinoza’s philosophy), there has been considerably less attention given to the nature of perfection and its relation to both power and the passions.2 Consider the following passages from Spinoza and Leibniz in which these two thinkers seem to bring together the issue of perfection and passion. In Ethics IIIp11s, Spinoza says the following: We see, then, that the Mind can undergo great changes, and pass now to a greater, now to a lesser perfection. These passions, indeed, explain to us the affects of Joy and Sadness. By Joy, therefore, I shall understand in what follows that passion by which the Mind passes to a greater perfection. And by Sadness, that passion by which it passes to a lesser perfection. The affect of Joy which is related to the Mind and Body at once I call Pleasure or Cheerfulness, and that of Sadness, Pain or Melancholy.3 And, in the Monadology §49, Leibniz says this: “The creature is said to act externally insofar as it is perfect, and to be acted upon [patir] by another, insofar as it is imperfect.”4 In other words, for Spinoza, the primitive passions of joy and sadness are cases in which a being’s perfection is increasing or decreasing, while, for Leibniz, any passion, it would..

A consequence of this view is that no non-actual individuals can truly be said to experience their worlds, nor can they ask the question if they are actual or not. (shrink)

Kant’s Thinker is an excellent and important addition to the literature. In it, Patricia Kitcher aims at arriving at a comprehensive understanding of Kant’s theory of the cognitive subject. To this end, she analyzes a central component of the most notoriously difficult part of the Critique of Pure Reason, the theory of the unity of apperception in the chapter on the Transcendental Deduction of the Categories. In Kitcher’s view, the ultimate payoff of such a study is that Kant’s theory can (...) “provide a ‘new’ source of illumination for current attempts to understand the nature of cognition and the mind” (3). This may be so. But the main value of the book will likely be for Kant scholars, who will appreciate the depth .. (shrink)

According to the standard view of his metaphysics, Leibniz endorses idealism: the thesis that the world is made up solely of minds or monads and their perceptual and appetitive states. Recently,this view has been challenged by some scholars, who argue that Leibniz can be seen as admitting corporeal substances, that is, animals or embodied souls, into his ontology, and that, therefore, it is false to attribute a strict idealism to him. Subtler accounts suggest that Leibniz begins his philosophical career as (...) an advocate of (some form of) the modern ‘mechanical’ philosophy and ends his career as an idealist, raising the issue when and why Leibniz adopts his monadological metaphysics. This article argues that, given a constellation of metaphysical, logical, and theological views, Leibniz is committed to the ontological primacy of mind or form even in his ‘middle years’. (shrink)

One of the more interesting topics debated by Leibniz and Locke and one that has received comparatively little critical commentary is the nature of essences and the classification of the natural world.1 This topic, moreover, is of tremendous importance, occupying a position at the intersection of the metaphysics of individual beings, modality, epistemology, and philosophy of language. And, while it goes back to Plato, who wondered if we could cut nature at its joints, as Nicholas Jolley has pointed out, the (...) debate between Leibniz and Locke has very clear similarities to the topic that has dominated the philosophy of language from the 1970s on: namely, the challenge mounted by Kripke, Kaplan, Putnam, and others against Russellian and Fregean descriptivist accounts of meaning. Yet, this topic is also, as Jolley writes, one of the “most elusive” in the debate between Leibniz and Locke.2 The purpose of this paper is to examine in detail Leibniz’s critique of Locke’s distinction between real and nominal essences. In doing so, I hope to show certain virtues in Leibniz’s account of metaphysics and philosophy of language that usually escape notice. While I wish to provide a general account of Leibniz’s disagreement with Locke, I also plan to focus on the nature of species and natural kinds. In my opinion, those who have treated this topic have not paid sufficient attention to Leibniz’s claims that “Essence is fundamentally nothing but the possibility of the thing under consideration” and “essences are everlasting because they only concern.

In his Between Two Worlds: A Reading of Descartes’s Meditations, John Carriero presents a sustained and sensitive interpretation of this seminal work of modern philosophy. The two worlds of the title are the worlds of Scholastic philosophy on the one side, and of the mechanical philosophy on the other, and it is Carriero’s argument that the Meditations are most helpfully understood against the background of Thomistic Scholasticism. In particular, Carriero shows that there is a deep difference between St. Thomas and (...) Descartes, first, concerning philosophical theology and the nature and possibility of our cognition of the divine essence, and second, concerning the nature of human cognition. What Carriero is ultimately trying to argue against is a picture of Descartes according to which he is fundamentally engaged in an anti-skeptical project and at the same time responsible for a crass and superficial form of dualism.While the book is organized simply, with one chapter devoted to each of the Descartes’s six Meditations, it is philosophically very rich and will reward careful study. Indeed, it is rare for a book to be devoted to such a close reading of a single text at this high level. Certainly, there are many “Introductions” for undergraduates, but few works written for advanced graduate students and professional philosophers cover a text so closely and so subtly. Carriero’s book demonstrates the virtues of this kind of text-immanent. (shrink)

In this paper, the author examines Leibniz inconsistent treatments of the existence predicate in his formulations of the ontological argument and elsewhere. It is shown that, contrary to expectations, Leibniz at times adumbrates insights often attributed to Kant and Frege.

Contrary to most interpretations of the transcendental deduction that take it to depend upon the ideas of personal identity, the “ownership” of mental states, or the ontological unity of the mind, the author argues that Kant’s principal concern is to show how the objective reality of a complex representation is consistent with the spontaneity of the mind. The short answer to this question is that objective reality is consistent with spontaneity precisely because the categories are universal and necessary. Ultimately, as (...) Dickerson emphasizes—and this is the novel claim of the book—the problem addressed within the B-deduction ought to be seen as the representationalist parallel to the semantic question of what it is to understand a complex sign or the question of the unity of a proposition.

This volume is a critical edition of the ten-year correspondence between Gottfried Wilhelm Leibniz, one of Europe’s most influential early modern thinkers, and Bartholomew Des Bosses, a Jesuit theologian who was keen to bring together Leibniz’s philosophy and the Aristotelian philosophy and religious doctrines accepted by his order. The letters offer crucial insights into Leibniz’s final metaphysics and into the intellectual life of the eighteenth century. Brandon C. Look and Donald Rutherford present seventy-one of Leibniz’s and Des Bosses’s (...) letters in the original Latin and in careful English translation. Few of the letters have been translated into English before. The editors also provide extensive annotations, deletions, and marginalia from Leibniz’s various drafts, and a substantial introduction setting the context for the correspondence and analyzing the main philosophical issues.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Individuation und Einzelnsein: Nietzsche, Leibniz, AristotelesBrandon C. LookPaola-Ludovika Coriando. Individuation und Einzelnsein: Nietzsche, Leibniz, Aristoteles. Frankfurt: Klostermann, 2003. Pp. ix. + 318. €28,00.What is a singular thing? Is there a first or last principle that allows us to call something an individual or one? What is the relation between the particular and the universal? Does the being of a particular mean the separation from the universal, or, on (...) the contrary, is the universal a post facto aggregation of individual subjects? What constitutes the individuality of man? This book, based on a lecture course given at the University of Freiburg, addresses these difficult questions and their answers by Nietzsche, Leibniz, and Aristotle.The author claims to limit the discussion to these philosophers because their philosophies represent distinct stations in the development of the question of individuation and the nature of individuality and, at the same time, because their different positions are both explicitly and implicitly related to each other (15). Coriando begins her discussion with Nietzsche, a philosopher one might not have linked at all to the "problem of individuation" per se, and moves backward in time to Leibniz and finally to Aristotle. The point of this order of presentation, the reader is told, is to trace back the essentials of the question of individuation to its origin: Aristotle (16). This strategy is largely successful.Nietzsche's primary concern, of course, is with the nature of the individual, or more particularly, the individual Mensch, and how he is distinguished from or distinguishes himself from the rest of the world. The answer, for Nietzsche, is to be found in his concept of the "will to power," which provides what Coriando calls his "ontological principle of individuation": the inherent drive for perspectival self-affirmation and self-increase (131). There is also, however, an "ethical principle of individuation": the attitude of a person vis-à-vis the eternal recurrence of the same. In accepting and letting go of the entirety of the world and its eternal recurrence, one "becomes who one is," and one can know one's individuality.Whereas Nietzsche tries to approach the problem of individuation independently of the entire western tradition of metaphysics, Leibniz is squarely within this tradition. Indeed, [End Page 121] in his first philosophical work, the Metaphysical Disputation on the Principle of Individuation, the sixteen-year-old Leibniz throws himself into a scholastic fray, carving out a strongly nominalist position. Leibniz's belief that only genuine individuals exist would, of course, stay with him throughout his career; the problem will be, as Coriando nicely shows, to give a precise account of the nature of individual substance. Coriando focuses on two works in her discussion, On the Correction of Metaphysics and the Concept of Substance and, to a much greater extent, the Monadology. The view that she extracts from these works should not be surprising. The principle of individuation, for Leibniz, rests in the active force of a monad and in the particular representation of the rest of the world from the monad's own point of view. Put this way, there is an interesting commonality with Nietzsche at work here.A similar commonality is shown with the thought of Aristotle. Here the principal concern is to explicate Aristotle's conception of ousia in De anima and MetaphysicsZ, H, and Q. Naturally, this leads into an account of how matter can be living and a further explication of Aristotle's energeia and entelecheia. In the end, it becomes clear that the set of concepts—energeia, conatus, will to power—are all, if not equivalent, at least performing largely the same role in guaranteeing the being of individuals. What has become "lost" in Aristotle's philosophy, however, is a notion like the perspectivalism present in Leibniz and Nietzsche, something that Coriando does not discuss at any length.This book offers a broad perspective on the question of individuation, and the choice of Nietzsche, Leibniz, and Aristotle allows Coriando to highlight interesting answers to this metaphysical problem. I do have two small quibbles. First, the problem of individuation, or the desire for a principium individuationis is so much a problem associated with medieval philosophy that... (shrink)

Its claims run counter to much contemporary discussion of Kant's theoretical philosophy and indeed challenge some of Kant's fundamental doctrines, but the arguments are very compelling and therefore likely (...) to force us to rethink both the Critique of Pure Reason [CPR] and Kant's relevance to contemporary epistemology.The central point of this work is that, if we follow Kant's injunction to engage in reflection on our cognitive capacities, then we will be led not to Kantian transcendental idealism but to an unqualified realism about objects and events in space and time. The book's first three chapters are devoted to analyzing Kant's methodology and the much-overlooked idea of transcendental affinity. Westphal focuses on the Kantian duty of engaging in "transcendental reflection," which is "the action through which I make the comparison of representations in general with the cognitive power in which they are situated, and through which I distinguish whether they are to be compared with one another as belonging to pure understanding or to sensible intuition" (CPR, A 261/B 317). And he adds to this the more general methodological obligation of "epistemic reflection," or the duty to determine precisely our cognitive capacities and incapacities. If, then, we reflect on our representations, their origins in sensibility and the understanding, and on our powers to know things of ourselves and the world in general, then certain puzzles arise—puzzles that were confronted by Kant (and Hume and Hegel) but that have not received the attention they have deserved. Chief among these puzzles is our ability to identify single objects and events and track them in space through time. But, as Westphal is keen to point out, identifying any particular over time requires that we be able to re-identify that particular. Now, while this puzzle is addressed by Kant in the Transcendental Deduction and Analogies of Experience, it is important to see that there is a material condition necessary for the possibility of self-conscious experience of the world that is not fleshed out in great detail by Kant and seems to be completely overlooked in the literature on Kant, namely, "the presupposition of diversity in nature" and the homogeneity of its objects among themselves (CPR, A 657/B 685). In other words, the fact that we are able to associate our various sensations with each other at all (and thereby identify and re-identify objects) is due to their "transcendental affinity." And it is Westphal's contention that "on Kant's own principles, the transcendental affinity of the manifold of sensory intuition can only be reconstructed, but not constructed, by intellectual syntheses of the understanding" (91). Therefore, pace Kant, who held that only his transcendental idealism could explain the possibility of experience, Westphal argues that transcendental idealism runs afoul of many of Kant's own arguments and observations in the Transcendental Aesthetic and Transcendental Analytic and, more important, that transcendental affinity provides grounds for "realism sans phrase" (the author's phrase) about objects and events in space and time, and for the view that our mental states are determined by external objects. As Westphal puts it in his conclusion: "Kant's analysis of transcendental affinity is in fact a transcendental argument for mental content externalism" (266). [End Page 665]The second part of Westphal's argument revolves around a detailed examination of Kant's theses about transeunt causality and the nature of matter as expressed not only in the Critique of Pure Reason, but also in the Metaphysical Foundations of Natural Science and the Opus postumum. Roughly the problem is this: in order to have an adequately grounded metaphysics of nature, Kant needs not only the results of the Analogies of Experience, the transcendental causal thesis that every event has a cause, but also the metaphysical causal thesis that every physical event has an external physical cause. But, according to Westphal, in the Metaphysical Foundations... (shrink)

Online data collection methods are expanding the ease and access of developmental research for researchers and participants alike. While its popularity among developmental scientists has soared during the COVID-19 pandemic, its potential goes beyond just a means for safe, socially distanced data collection. In particular, advances in video conferencing software has enabled researchers to engage in face-to-face interactions with participants from nearly any location at any time. Due to the novelty of these methods, however, many researchers still remain uncertain about (...) the differences in available approaches as well as the validity of online methods more broadly.

Direct comparison of the two methods within each study as well as a meta-analysis of all studies suggest that the results from the two methods are comparable, providing empirical support for the validity of moderated online data collection. Finally, we discuss current limitations of online data collection and possible solutions, as well as its potential to increase the accessibility, diversity, and replicability of developmental science.

Media multitasking entails simultaneously engaging in multiple tasks when at least one of the tasks involves media. Across two studies, we investigated one potential trigger of media multitasking, state boredom, and its relation to media multitasking. To this end, we manipulated participants’ levels of state boredom using video mood inductions prior to administering an attention-demanding 2-back task during which participants could media multitask by playing a task-irrelevant video. We also examined whether trait boredom proneness was associated media multitasking. We found (...) no direct evidence that state boredom leads to media multitasking. However, trait boredom proneness correlated with greater amounts of media multitasking in Experiment 1, but not in Experiment 2. Surprisingly, in both experiments, post-task ratings of state boredom were equivalent across conditions, alerting us to the short-lived effects of video mood inductions and the boring nature of cognitive tasks.

Evangelical scholars have recently offered criticisms of mind-body dualism from the disciplines of theology, philosophy, and neuroscience. We offer several arguments as to why these reasons for abandoning mind-body dualism fail. Additionally, we offer a positive thesis, a dualism that brings together the best aspects of the Cartesian view and the Thomistic view of human persons. The result is a substance dualism that treats the nature of embodiment quite seriously. This view explains why we, as souls, require a resurrected body (...) as well as accounting for the great good of our embodiment in general. A human person is at the same time wholly soul and yet fully bodily. (shrink)

This study explores the relationship between decision-making styles and moral judgements to understand how maximizers and satisficers differ in their analysis of ethical dilemmas. It also explores the linkage between decision-making styles and the moral reasoning perspectives of absolutism and relativism, investigating if ethical ideologies play a mediating role in how maximizers and satisficers evaluate ethical situations. In order to test these relationships, data is collected from a sample of 187 upper level business students. Results indicate that maximizers are significantly (...) more likely than satisficers to judge ethically ambiguous actions as immoral. Underlying this effect, maximizers (vs. satisficers) have a more idealistic ethical ideology. (shrink)

This paper tries to show that there is an important virtue (with no generally recognized name) that could be called “accountability.” This virtue is a trait of a person who embraces being held accountable and consistently displays excellence in relations in which the person is held accountable.

Empirical implications and an agenda for future research are briefly discussed. Possible objections to the (...) virtue are considered and rebutted, and relations to other virtues, particularly the personal virtue of justice, are discussed. In conclusion, we suggest that though this virtue has not received the attention it deserves in contemporary society, it has been more clearly recognized in other cultures. Some of the reasons for the partial eclipse of the virtue are understandable and justifiable, but there are good reasons to think our society would be improved if we paid more attention to accountability from a virtue perspective.

The link between human nature and human flourishing is undeniable. "A healthy tree cannot bear bad fruit, nor can a diseased tree bear good fruit" (Matt. 7:18). The ontology of the human person will, therefore, ground the nature of human flourishing and thereby sanctification. Spiritual formation is the area of Christian theology that studies sanctification, the Spirit-guided process whereby disciples of Jesus are formed into the image of Jesus (Rom. 8:28-29; 2 Cor. 3:18; 2 Peter 3:18). Until the nineteenth century, (...) there was an overwhelming consensus among Christian thinkers that some form of mind-body (or soul-body) dualism is true of human beings. Recently, that consensus has eroded, and with it the availability of a shared body of knowledge about spiritual formation. Some Christian physicalists argue that dualism is incompatible with central elements of spiritual formation. Neuroscientist Warren Brown and psychologist Brad Strawn offer the only substantive account of spiritual formation from the view of Christian physicalism and its accompanying objections to dualism. It is on their arguments that this chapter focuses. We argue that Brown and Strawn fail to support their incompatibility thesis. Additionally, we argue that Christian physicalism stands in tension with important philosophical and theological foundations of Christian spiritual formation. In doing so we offer a specific form of dualism, the bodily soul view, and explain how this view illuminates the importance of embodiment, our neurological and social development, and hence the important physical aspects of Christian spiritual formation.

Empirical implications and an agenda for future research are briefly discussed. Possible objections to the virtue are considered and rebutted, (...) and relations to other virtues, particularly the personal virtue of justice, are discussed. In conclusion, we suggest that though this virtue has not received the attention it deserves in contemporary society, it has been more clearly recognized in other cultures. Some of the reasons for the partial eclipse of the virtue are understandable and justifiable, but there are good reasons to think our society would be improved if we paid more attention to accountability from a virtue perspective.

The connection between Spinoza and Nietzsche has often been remarked upon in the literature on the two thinkers.1 Not surprisingly, Nietzsche himself first noticed the similarity between his (earlier) thought and the thought of Spinoza, remarking to Overbeck in an oft-quoted postcard, “I have a precursor, and what a precursor!” He goes on to say, “Not only is his over-all tendency like mine – making knowledge the most powerful affect – but in five main points of his doctrine I recognize (...) myself; this most unusual and loneliest thinker is closest to me in precisely these matters: he denies the freedom of the will, teleology, the moral world order, the unegoistic, and evil. Even though the divergences are admittedly tremendous, they are due more to the difference in time, culture, and science.”2 One aspect of his own thought that Nietzsche does not list here, however, is his “doctrine” of “becoming who one is.” Is this an example of a point at which Spinoza and Nietzsche’s views separate? In this paper, I should like to consider whether or not Spinoza could plausibly be understood to have had a similar view; that is, I should like to examine whether or not the process for Spinoza of achieving happiness and beatitude can be seen principally as an instance of “becoming who one is.” There are, of course, some obvious and notorious difficulties in trying to understand what Nietzsche meant by the phrase “to become who one is.” After all, Nietzsche seems to deny both the existence of the self (as substance) and being in general, saying that there is only becoming. What, then, might this phrase mean? As this paper concerns principally the philosophy of Spinoza, I do not want to get too bogged down in the difficulties involved in interpreting Nietzsche; rather, I wish to follow without further argument the..

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Philosophy 39.3 (2001) 440-442 [Access article in PDF] Reinhard Lauth. Descartes ' Konzeption des Systems der Philosophie. Stuttgart (Bad Cannstatt): Frommann-Holzboog, 1998. Pp. x + 227 pp. Cloth, DM 64.00. Reinhard Lauth's Descartes ' Konzeption des Systems der Philosophie is an interesting addition to the literature on Descartes. Written by a renowned scholar of German Idealism, it does not represent an attempt to respond (...) to scholars of Descartes, to take part in the debate regarding aspects of Descartes's philosophy, nor to explain the role of Descartes's thought in the tumultuous seventeenth century, but rather to explain to scholars of German Idealism why Descartes should be considered the first and one of the greatest transcendental philosophers. It is no accident that in the index we find close to 50 references each to Kant and Fichte, while Descartes's important "rationalist" comrades, Spinoza and Leibniz, receive half as much attention; nor is it an accident that the first and last philosopher mentioned in the book is Fichte.Lauth's book is in the tradition of Gueroult's monumental Descartes selon l ' ordre des raisons (Paris, 1968, 2nd edition) and, as the title indicates, the subject of the book is Descartes's philosophy as a system, not as a collection of independent theses about various philosophical problems. However, unlike Gueroult, who concentrated on an [End Page 440] analysis of the Meditations, Lauth draws extensively on the Rules for the Direction of the Mind, Discourse on Method, Meditations, and Descartes's correspondence. That Descartes viewed philosophy as ideally constituting a system of human knowledge should not come as news to anyone who recalls Descartes's claim in the Preface to the Principles of Philosophy that all of philosophy is like a tree whose roots are metaphysics, trunk physics, and branches medicine, mechanics, and morals, or his claim in the Preface to the Meditations that there is a clear order of argumentation or reasons and that his goal is to lay bare the foundations of philosophy. How exactly Descartes's philosophy is to constitute a system is the trickier question that is Lauth's concern.According to Lauth, the order of reasons that one finds expressed in Descartes's first philosophy is not simply a series of biographical events, filling a psychological need in Descartes (cf. Alquié, La Découverte métaphysique de l ' homme chez Descartes [Paris, 1966]), but rather the "systematic path of the cogito itself" (X). And Lauth attempts to show that there is something inexorable in the way that conclusions about the world from the point of view of the thinking subject are made and follow from one another. This takes him along the well-known path of the Meditations: from the existence of the self, to the nature of the self, to the existence and nature of God, to the external world, and finally to the relation of mind and body. And here two interesting observations on Lauth's part should be singled out. First, Lauth does an admirable job in intimating the tension regarding the places of the thinking subject and God as the supreme principles in Descartes's system. On the one hand, it would seem that the thinking subject should be the highest principle in Descartes's philosophy insofar as its existence is the first thing known; but, according to Lauth, it cannot be the highest principle because it does not contain the principle of its own existence (76). On the other hand, if we claim that God is the highest principle then we must recognize that a system following from this principle must fail insofar as genuine knowledge of God surpasses the bounds of our finite, human knowledge (99-100). Second, in claiming that Descartes was a "transcendental philosopher," Lauth reminds us of the extent to which Descartes is concerned with the bounds of human knowledge as determinable from the thinking subject itself.While this work contains many useful insights—especially for those scholars of German Idealism who are looking for new ways of reflecting on their subject—it has...

Sober (1992) has recently evaluated Brandon's (1982, 1990; see also 1985, 1988) use of Salmon's (1971) concept of screening-off in the philosophy of biology. He critiques three particular issues, each of which will be considered in this discussion.
