This book gathers together for the first time an important body of texts written between 1672 and 1686 by the great German philosopher and polymath Gottfried Leibniz. These writings, most of them previously untranslated, represent Leibniz's sustained attempt on a problem whose solution was crucial to the development of his thought, that of the composition of the continuum. The volume begins with excerpts from Leibniz's Paris writings, in which he tackles such problems as whether the infinite division of matter entails (...) perfect points, whether matter and space can be regarded as true wholes, whether motion is truly continuous, and the nature of body and substance. Comprising the second section is Pacidius Philalethi, Leibniz's brilliant dialogue of late 1676 on the problem of the continuity of motion. In the selections of the final section, from his Hanover writings of 1677-1686, Leibniz abandons his earlier transcreationism and atomism in favor of the theory of corporeal substance, where the reality of body and motion is founded in substantial form or force.Leibniz's texts (one in French, the rest in Latin) are presented with facing-page English translations, together with an introduction, notes, appendixes containing related excerpts from earlier works by Leibniz and his predecessors, and a valuable glossary detailing important terms and their translations.

This book, first published in 1975, provides critical and comprehensive introduction to the philosophy of Leibniz.

In his well-known Discourse on Metaphysics , Leibniz puts individual substance at the basis of metaphysical building. In so doing, he connects himself to a venerable tradition. His theory of individual concept, however, breaks with another idea of the same tradition, that no account of the individual as such can be given. Contrary to what has been commonly accepted, Leibniz’s intuitions are not the mere result of the transcription of subject-predicate logic, nor of the uncritical persistence of some old metaphysical (...) assumptions. They grow, instead, from an unprejudiced inquiry about our basic ontological framework, where logic of truth, linguistic analysis, and phenomenological experience of the mind’s life are tightly interwoven. Leibniz’s struggle for a concept capable of grasping concrete individuals as such is pursued in an age of great paradigm changes – from the Scholastic background to Hobbes’s nominalism to the Cartesian ‘way of ideas’ or Spinoza’s substance metaphysics – when the relationships among words, ideas and things are intensively discussed and wholly reshaped. This is the context where the genesis and significance of Leibniz’s theory of ‘complete being’ and its concept are reconstrued. The result is a fresh look at some of the most perplexing issues in Leibniz scholarship, like his ideas about individual identity and the thesis that all its properties are essential to an individual. The questions Leibniz faces, and to which his theory of individual substance aims to answer, are yet, to a large extent, those of contemporary metaphysics: how to trace a categorial framework? How to distinguish concrete and abstract items? What is the metaphysical basis of linguistic predication? How is trans-temporal sameness assured? How to make sense of essential attributions? In this ontological framework Leibniz’s further questions about the destiny of human individuals and their history are spelt out. Maybe his answers also have something to tell us. This book is aimed at all who are interested in Leibniz’s philosophy, history of early modern philosophy and metaphysical issues in their historical development. (shrink)

This book offers a sustained re-evaluation of the most central and perplexing themes of Leibniz's metaphysics. In contrast to traditional assessments that view the metaphysics in terms of its place among post-Cartesian theories of the world, Jan Cover and John O'Leary-Hawthorne examine the question of how the scholastic themes which were Leibniz's inheritance figure - and are refigured - in his mature account of substance and individuation. From this emerges a fresh and sometimes surprising assessment of Leibniz's views on modality, (...) the Identity of Indiscernibles, form as an internal law, and the complete-concept doctrine. As a rigorous philosophical treatment of a still-influential mediary between scholastic and modern metaphysics, their study will be of interest to historians of philosophy and contemporary metaphysicians alike.

EDITOR'S INTRODUCTION T JLJe1bn1z was above all things a metaphysician. That does not mean that his head was in the clouds, or that the particular sciences ...

In the New Essays on Human Understanding, Leibniz argues chapter by chapter with John Locke's Essay Concerning Human Understanding, challenging his views about knowledge, personal identity, God, morality, mind and matter, nature versus nurture, logic and language, and a host of other topics. The work is a series of sharp, deep discussions by one great philosopher of the work of another. Leibniz's references to his contemporaries and his discussions of the ideas and institutions of the age make this a fascinating (...) and valuable document in the history of ideas. The work was originally written in French, and the version by Peter Remnant and Jonathan Bennett, based on the only reliable French edition (published in 1962), first appeared in 1981 and has become the standard English translation. It has been thoroughly revised for this series and provided with a new and longer introduction, a chronology on Leibniz's life and career and a guide to further reading. (shrink)

The selections contained in these volumes from the papers and letters of Leibniz are intended to serve the student in two ways: first, by providing a more adequate and balanced conception of the full range and penetration of Leibniz's creative intellectual powers; second, by inviting a fresher approach to his intellectual growth and a clearer perception of the internal strains in his thinking, through a chronological arrangement. Much confusion has arisen in the past through a neglect of the develop ment (...) of Leibniz's ideas, and Couturat's impressive plea, in his edition of the Opuscu/es et fragments (p. xii), for such an arrangement is valid even for incomplete editions. The beginning student will do well, however, to read the maturer writings of Parts II, III, and IV first, leaving Part I, from a period too largely neglected by Leibniz criticism, for a later study of the still obscure sources and motives of his thought. The Introduction aims primarily to provide cultural orientation and an exposition of the structure and the underlying assumptions of the philosophical system rather than a critical evaluation. I hope that together with the notes and the Index, it will provide those aids to the understanding which the originality of Leibniz's scientific, ethical, and metaphysical efforts deserve. (shrink)

This is the most up-to-date and comprehensive interpretation of the philosophy of Gottfried Wilhelm Leibniz. Amongst its other virtues, it makes considerable use of unpublished manuscript sources. The book seeks to demonstrate the systematic unity of Leibniz's thought, in which theodicy, ethics, metaphysics and natural philosophy cohere. The key, underlying idea of the system is the conception of nature as an order designed by God to maximise the opportunities for the exercise of reason. From this idea emerges the view that (...) this world is the best of all possible worlds, and an ethical ideal in which the well-being of human beings is promoted through the gradual extension of intellectual enlightenment.

In diesem Aufsatz wird das Problem der Inkompossibilität bei Leibniz diskutiert. Zwei mögliche Substanzen sind inkompossibel, wenn und nur wenn es nicht möglich ist, daß sie in einer gemeinsamen Welt existieren, d. h. es für Gott unmöglich ist, eine Welt zu erschaffen, in der beide Substanzen existieren. Der Begriff von Inkompossibilität ist nun jedoch aufgrund der völligen Unabhängigkeit der Substanzen voneinander in Gefahr, sich als gehaltlos zu erweisen. Unser Ausgangspunkt im Folgenden ist Hintikkas Analyse des Problems. Wir versuchen zu zeigen, (...) wie es für Leibniz möglich ist, in seiner Theorie der Individuation ohne Relationen auszukommen und sich auf sie dennoch zu stützen, um dem Begriff der Inkompossibilität Gehalt zu verleihen. Dazu bedienen wir uns auch der Ideen von Russell über die Quelle der Inkompossibilität bei Leibniz: Um ihre Herkunft aufzuspüren, müssen wir das Konzept von der Welt, welches Leibniz verwandt hat, noch beleuchten -unsere Lösung des Problems kann dann als eine Art Synthese der sogenannten analytischen und synthetischen Lösungen angesehen werden.

By what process of development he came to this opinion, though in itself an important and interesting question, is logically irrelevant to the inquiry how far the opinion itself is correct ; and among his opinions, when these have been ascertained, it becomes desirable to prune away such as seem inconsistent with his main doctrines, before those doctrines themselves are subjected to a critical scrutiny. Philosophic truth and falsehood, in short, rather than historical fact, are what primarily demand our attention (...) in this inquiry. (shrink)

During the seventeenth century, disputes over middle knowledge centered on the following question: does God know contingent states of affairs before He decrees to bring them about (the Jesuit view); or, conversely, does He know them after He has decreed which states of affairs He will bring about (the Dominican view)? This article intends to cast some light on Leibniz’s view of this question. Of central importance here is the notion of a possible decree (designed both to ground contingency and (...) to explain God’s knowledge). Despite his apparent proximity to the Dominican view, Leibniz maintained the prevolitional nature of God’s knowledge of contingent states of affairs. In order to establish this point, Leibniz’s view is compared to some little known developments in the theory of middle knowledge. (shrink)

Legendary since his own time as a universal genius, Gottfried Wilhelm Leibniz (1646-1716) contributed significantly to almost every branch of learning. One of the creators of modern mathematics, and probably the most sophisticated logician between the Middle Ages and Frege, as well as a pioneer of ecumenical theology, he also wrote extensively on such diverse subjects as history, geology, and physics. But the part of his work that is most studied today is probably his writings in metaphysics, which have been (...) the focus of particularly lively philosophical discussion in the last twenty years or so. The writings contain one of the great classic systems of modern philosophy, but the system must be pieced together from a vast and miscellaneous array of manuscripts, letters, articles, and books, in a way that makes especially strenuous demands on scholarship. This book presents an in-depth interpretation of three important parts of Leibniz's metaphysics, thoroughly grounded in the texts as well as in philosophical analysis and critique. The three areas discussed are the metaphysical part of Leibniz's philosophy of logic, his essentially theological treatment of the central issues of ontology, and his theory of substance (the famous theory of monads).
