In this extraordinary work Gilles Deleuze reflects on one of the figures of the past who has most influenced his own sweeping reconfiguration of the tasks of philosophy.

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).

This book offers a major reassessment of Leibniz's metaphysics. Christia Mercer has exposed the underlying doctrines of Leibniz's philosophy. By analysing Leibniz's early works she demonstrates that the metaphysics of pre-established harmony developed many years earlier than previously believed and for reasons which have not been understood. As a result of this analysis she has unearthed a philosophical school that Leibniz scholars have not recognized. A much deeper understanding of some of Leibniz's key doctrines emerges. Moreover, since the Leibniz that (...) is revealed here does not fit neatly into the standard accounts of the history of philosophy and science, Christia Mercer's study will prompt scholars to reconsider their basic assumptions about early modern philosophy and science.

This book is the fruit of twenty-five years of study of Spinoza by the editor and translator of a new and widely acclaimed edition of Spinoza's collected works.

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.

Robert M. Adams’s Leibniz: Determinist, Theist, Idealist will be a landmark in Leibniz scholarship. It is a privilege to be asked to comment on it.

John Carriero, Massimo Mugnai, and Daniel Garber have all contributed significantly to our understanding of Leibniz. I am honored to have my book discussed by such distinguished Leibniz interpreters, and their present reviews all push me in ways that I find instructive. I will first discuss issues pertaining to contingency, responding to Carriero’s review and most of Mugnai’s; then issues about bodies, responding to Garber’s review and the last part of Mugnai’s.

This is arguably the seminal work in historical andphilosophical analysis of the twentieth century.

The eleventh-century philosopher and physician Abu Ali ibn Sina (d. A.D. 1037) was known in the West by his Latinized name Avicenna. An analysis of the sources and evolution of Avicenna's metaphysics, this book focuses on the answers he and his predecessors gave to two fundamental pairs of questions: what is the soul and how does it cause the body; and what is God and how does He cause the world? To respond to these challenges, Avicenna invented new concepts and (...) distinctions and reinterpreted old ones. The author concludes that Avicenna's innovations are a turning point in the history of metaphysics. Avicenna's metaphysics is the culmination of a period of synthesis during which philosophers fused together a Neoplatonic project (reconciling Plato with Aristotle) with a Peripatetic project (reconciling Aristotle with himself). Avicenna also stands at the beginning of a period during which philosophers sought to integrate the Arabic version of the earlier synthesis with Islamic doctrinal theology (kalam). Avicenna's metaphysics significantly influenced European scholastic thought, but it had an even more profound impact on Islamic intellectual history--the philosophical problems and opportunities associated with the Avicennian synthesis continued to be debated up to the end of the nineteenth century.

IDEAS. and. MECHANISM. Essays on Early Modern Philosophy MARGARET DAULER WILSON For more than three decades, Margaret Wilson's essays on early modern philosophy have influenced scholarly debate. Many are considered  ...

"With an astonishing erudition... and in a direct no-nonsense style, Bennett expounds, compares, and criticizes Spinoza’s theses.... No one can fail to profit from it. Bennett has succeeded in making Spinoza a philosopher of our time." --W. N. A. Klever, _Studia Spinoza_.

Richard Popkin’s meticulous translation--the most complete since the eighteenth century--contains selections from thirty-nine articles, as well as from Bayle’s four Clarifications. The bulk of the major articles of philosophical and theological interest--those that influenced Leibniz, Berkeley, Hume, and Voltaire and formed the basis for so many eighteenth-century discussions--are present, including David, Manicheans, Paulicians, Pyrrho, Rorarius, Simonides, Spinoza, and Zeno of Elea.

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.

This book is the fullest study in English for many years on the role of God in Spinoza's philosophy. Spinoza has been called both a 'God-intoxicated man' and an atheist, both a pioneer of secular Judaism and a bitter critic of religion. He was born a Jew but chose to live outside any religious community. He was deeply engaged both in traditional Hebrew learning and in contemporary physical science. He identified God with nature or substance: a theme which runs through (...) his work, enabling him to naturalise religion but - equally important - to divinise nature. He emerges not as a rationalist precursor of the Enlightenment but as a thinker of the highest importance in his own right, both in philosophy and in religion. (shrink)

the philosophers in the West, none, perhaps, is better known by name and less familiar in actual content of his ideas than the medieval Muslim philosopher, physician, minister and naturalist Abu Ali Ibn Sina, known since the days of the scholastics as Avicenna. In this book the author, himself a philosopher, and long known for his studies of Arabic thought, presents a factual account of Avicenna's philosophy. Setting the thinker in the context of his often turbulent times and tracing the (...) roots and influences of Avicenna's ideas, this book offers a factual philosophical portrait. It details Avicenna's account of being as a synthesis between the seemingly irreconcilable extremes of Aristotelian eternalism and the creationism of monotheistic scripture. It examines Avicenna's distinctive theory of knowledge, his ideas about immortality and individuality, including the famous "floating man argument", his contributions to logic, and his probing thoughts on rhetoric and poetics.

MORE THAN MOST PHILOSOPHERS, Spinoza needed a coherent and sophisticated set of views on the nature of possibility: many of his most important philosophical positions and arguments depended on it. As one example, take Ethics IP33. This Proposition—among the most famous of the Ethics— states, “Things could have been produced by God in no other way, and in no other order than they have been produced.” In a salutary attempt to clarify the meaning of IP33 et relata, Spinoza adds in (...) the first Scholium to IP33 that “by these propositions I have shown more clearly than the noon light that there is absolutely nothing in things on account of which they can be called contingent.” Now, such assertions were bound to give rise to numerous objections and Spinoza knew it. To meet these objections, he immediately proceeds to one of the most powerful: namely, are there not things that actually have been “produced by God” that need not have been “produced by God?” And would it not make sense to call these things “contingent or possible?” In reply, Spinoza reinterprets the concept of possibility. We call existing things “contingent” “only because of a defect of our knowledge.” There are, he continues, two types of deficiency that lead us to regard existing things as “contingent or possible”: either we do not know “that the thing’s essence involves a contradiction” or we do know that the thing’s essence does not involve a contradiction but we do not know enough about the “order of causes” to affirm anything “certainly about its existence.”.

Im folgenden komme ich zu dem Ergebnis, daß Gott nicht wählt, welche Welt er wählen solle, er wählt vielmehr eine besondere Definition von Vollkommenheit. Diese gilt dann als Kriterium für die Wahl der Welt. Meine Argumente für dieses Ergebnis zeigen, daß jeder wohldefinierte Seinsbereich eine eigene Definition von Vollkommenheit benötigt und all diese Definitionen logisch konsistent sein müssen. Beispiele für Definitionen werden angeführt. In diesem Zusammenhang weise ich nach, inwiefern Candides moralische Einwürfe Leibniz' mathematischphysizistischen Gott nicht treffen.

Im Falle einer kontingenten Wahrheit 'S ist P' behauptet Leibniz sowohl, daß der Begriff von P im Begriff von S enthalten ist als auch, daß die Verbindung von S und P durch den göttlichen Willen besteht: Wie kann das angehen? Ich beantworte diese Frage, indem ich eine Deutung der Leibnizschen Doktrin von Wahrheit als Enthaltensein und seiner Auffassung vom vollständigen Begriff einer individuellen Substanz anbiete, nach der jene seinen Überlegungen darüber entspringen, inwiefern die 'Neue Wissenschaft' sich mit der traditionellen Unterscheidung (...) von Essenz und Akzidens nicht gut verträgt. Aus meiner Interpretation folgt dann, daß Leibniz' Theorie begrifflichen Enthaltenseins wie die verwandte Theorie der unendlichen Analyse auf einer Struktur beruhen, die in einigen, aber, wie sich zeigen läßt, nicht in allen möglichen physikalischen Ordnungen aufgefunden werden kann. Ich werde darlegen, daß diese Einsicht meine Interpretation nicht untergräbt. Zum Schluß deute ich an, inwiefern sich Leibniz' Überlegungen zur Kontingenz in Begriffen göttlicher Vermögen und in Begriffen unendlicher Komplexität ergänzen. (shrink)
