This is the first volume compiling English translations of Leibniz's journal articles on natural philosophy, presenting a selection of 26 articles, only three of which have appeared before in English translation. It also includes in full Leibniz's public controversies with De Catelan, Papin, and Hartsoeker. The articles include work in optics, on the fracture strength of materials, and on motion in a resisting medium, and Leibniz's pioneering applications of his calculus to these issues by construing them as mini-max and inverse tangent problems. Other topics covered by the articles include: criticisms of the Cartesian estimate of motive force and Leibniz's proposal of a different way of estimating force to replace it; a proposed theory of celestial motions and gravitation, and derivation of the inverse square law; challenge problems concerning the isochronous curve and the catenary; a sample of work on gaming theory; and Leibniz's critique of atomism.

The Discourse on Metaphysics is one of Leibniz´s fundamental works. Written around January 1686, it is the most accomplished systematic expression of Leibniz's philosophy in the 1680s, the period in which Leibniz's philosophy reached maturity. Leibniz's goal in the Discourse is to give a metaphysics for Christianity; that is, to provide the answers that he believes Christians should give to the basic metaphysical questions. Why does the world exist? What is the world like? What kinds of things exist? And what is the place of human beings in the world? To this purpose Leibniz discusses some of the most traditional topics of metaphysics, such as the nature of God, the purpose of God in creating the world, the nature of substance, the possibility of miracles, the nature of our knowledge, free will, and the justice behind salvation and damnation. This volume provides a new translation of the Discourse, complete with a critical introduction and a comprehensive philosophical commentary.

Leibniz published the Dissertation on Combinatorial Art in 1666. This book contains the seeds of Leibniz's mature thought, as well as many of the mathematical ideas that he would go on to further develop after the invention of the calculus. It is in the Dissertation, for instance, that we find the project for the construction of a logical calculus clearly expressed for the first time. The idea of encoding terms and propositions by means of numbers, later developed by Kurt Gödel, also appears in this work. In this text, furthermore, Leibniz conceives the possibility of constituting a universal language or universal characteristic, a project that he would pursue for the rest of his life. Mugnai, van Ruler, and Wilson present the first full English translation of the Dissertation, complete with a critical introduction and a comprehensive commentary.

This volume brings together 124 of Leibniz's writings on some of his most distinctive and ambitious projects including developing a new logic or art of discovery as a tool for uncovering new truths; creating a universal language with a rational, philosophical grammar structured to reflect human reasoning; designing a symbolic script (the characteristic) to facilitate discoveries across all fields of knowledge; planning an encyclopaedia in which existing knowledge would be systematically arranged to yield new insights; and advancing his vision of a collaborative, higher­order science (the general science) that would encompass the foundational principles of all other sciences.The writings in this volume trace the evolution and interconnection of these projects during Leibniz's formative first decade in Hanover (1677–1686), and is the most extensive collection of such writings in English to date. Strickland has returned to Leibniz's original manuscripts to produce accurate, carefully annotated translations that document textual variations, deletions, and marginalia. Of the 124 texts included, 86 appear here in English for the first time, while five have never been published in any language.In addition to the translations, the volume features a substantial introductory essay on Leibniz's life, work, and writings on a universal language, the characteristic, logic, the encyclopaedia, and general science from 1677 to 1686, along with detailed explanatory notes on each text, providing context, background, and the rationale for their dating.

This volume brings together 138 of Leibniz's writings on four key areas of philosophy–metaphysics, natural philosophy, ethics, and jurisprudence. His metaphysical writings trace the development of some of his most distinctive doctrines such as the complete concept theory of substance, pre­established harmony, the nature of human and divine freedom, and the infinite analysis of contingent truths. Leibniz's writings on natural philosophy reveal a conviction that the principles of physics ultimately depend on those of metaphysics and his efforts to develop a rational physics grounded not in experiments but in an a priori investigation of intelligible and sensible qualities, such as figure, motion, and colour. The ethical writings focus on happiness, the role of virtue, and the importance of adopting others' perspectives. Meanwhile, Leibniz's jurisprudential works centre on his ambition to create a systematic, rational foundation for law and his plan to reform legal codes by integrating Roman law with modern European jurisprudence.This collection traces the evolution and interconnection of these ideas and projects during Leibniz's formative first decade in Hanover (1677–1686), and is the most extensive collection of such writings in English to date.

This volume brings together 52 of Leibniz's writings on religion and theology, including the book­length Examination of the Christian Religion, in which he defends the Roman Catholic position on various matters of controversy, despite being a lifelong Lutheran himself. Also included are the complete texts from an unfinished project, Apology for Catholic Truth, in which Leibniz writes in the guise of a Catholic. Other writings reflect several of Leibniz's long­term projects: constructing a philosophical defence of Christianity to show the compatibility of its doctrines with reason; undermining philosophies he believed could lead to atheism, in particular those of Hobbes, Descartes, Spinoza; and developing methods for resolving theological disputes.This collection traces the evolution of these projects during Leibniz's formative first decade in Hanover (1677–1686), offering the most comprehensive English-language selection of such writings to date. Strickland has returned to Leibniz's original manuscripts to produce accurate, carefully annotated translations that document textual variations, deletions, and marginalia.
