This volume brings together a number of original articles by leading Leibniz scholars to address the meaning and significance of Leibniz’s notions of compossibility and possible worlds. In order to avoid the conclusion that everything that exists is necessary, or that all possibles are actual, as Spinoza held, Leibniz argued that not all possible substances are compossible, that is, capable of coexisting. In Leibniz’s view, the compossibility relation divides all possible substances into disjoint sets, each of which constitutes a possible world, or a way that God might have created things. For Leibniz, then, it is the compossibility relation that individuates possible worlds; and possible worlds form the objects of God’s choice, from among which he chooses the best for creation. Thus the notions of compossibility and possible worlds are of major significance for Leibniz’s metaphysics, his theodicy, and, ultimately, for his ethics. Given the fact, however, that none of the approaches to understanding Leibniz’s notions of compossibility and possible words suggested to date have gained universal acceptance, the goal of this book is to gather a body of new papers that explore ways of either refining previous interpretations in light of the objections that have been raised against them, or ways of framing new interpretations that will contribute to a fresh understanding of these key notions in Leibniz’s thought.

This book reveals a thread that runs through Leibniz’s metaphysics: from his logical notion of possible individuals to his notion of actual, nested ones. It presents Leibniz’s subtle approach to possibility and explores some of its consequential repercussions in his metaphysics. The book provides an original approach to the questions of individuation and relations in Leibniz, offering a novel account of Leibniz’s notion of Nested Individuals.

This major contribution to Leibniz scholarship will prove invaluable to historians of philosophy, theology, and science.

An unparalleled collection of original essays on Benedict de Spinoza's contributions to philosophy and his enduring legacy A Companion to Spinoza presents a panoramic view of contemporary Spinoza studies in Europe and across the Anglo-American world. Designed to stimulate fresh dialogue between the analytic and continental traditions in philosophy, this extraordinary volume brings together 53 original essays that explore Spinoza's contributions to Western philosophy and intellectual history. A diverse team of established and emerging international scholars discuss new themes and classic topics to provide a uniquely comprehensive picture of one of the most influential metaphysicians of all time. Rather than simply summarizing the body of existing scholarship, the Companion develops new ideas, examines cutting-edge scholarship, and suggests directions for future research. The text is structured around six thematically-organized sections, exploring Spinoza's life and background, his contributions to metaphysics and natural philosophy, his epistemology, politics, ethics, and aesthetics, the reception of Spinoza in the work of philosophers such as Kant, Schelling, Schopenhauer, and Hegel, and more. This unparalleled research collection combines a timely overview of the current state of research with deep coverage of Spinoza's philosophy, legacy, and influence. Part of the celebrated Blackwell Companions to Philosophy series, A Companion to Spinoza is an ideal text for advanced courses in modern philosophy, intellectual history, and the history of metaphysics, and an indispensable reference for researchers and scholars in Spinoza studies.

Although Leibniz's writing forms an enormous corpus, no single work stands as a canonical expression of his whole philosophy. In addition, the wide range of Leibniz's work--letters, published papers, and fragments on a variety of philosophical, religious, mathematical, and scientific questions over a fifty-year period--heightens the challenge of preparing an edition of his writings in English translation from the French and Latin.

Introduces readers to the history of necessity and possibility, two modal concepts which play a key role in philosophy.
