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.

I shall proceed in the following way. In parts II and III of this paper, I shall discuss the strengths and weaknesses of the interpretation put forward by Robert Merrihew Adams in his recent book, and I shall expand upon this account, discussing a crucial but hitherto unexamined aspect of the relation between dominant and subordinate monads, reconstructed from Leibniz's letters to Des Bosses and his essays of 1714, _Principles of Nature and Grace and Monadology. In part IV of this paper, I shall examine various difficulties that arise both for my interpretation and, more generally, for Leibniz's account of the relation of domination and subordination.

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..

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.

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 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

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..

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.

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 ..

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...

The book under review contains a selection of the papers presented at the conference “Leibniz and Adam,” held in Tel Aviv and Jerusalem from December 29, 1991 to January 2, 1992. The object of the conference and the book was to consider the role of Adam, the first man, in Leibniz’s thought and, in doing so, “to provide an unusual view of the interrelations between his metaphysics, philosophy of religion, philosophy of language, theory of knowledge, logic, attidude vis-à-vis mysticism, philosophy of history, philosophy of nature, ethics, and philosophical anthropology”.
