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 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, this study will be of interest to historians of philosophy and contemporary metaphysicians alike.

Leibniz's earliest philosophy and its importance for his mature philosophy have not been examined in detail, particularly in the level of detail that one can achieve by placing Leibniz's philosophy in the context of the sources for two of the most basic concerns of his philosophical career: his metaphysics of individuals and the principle oftheir individuation. In this book I provide for the first time a detailed examination of these two Leibnizian themes and trace its implications for how we should interpret other major Leibnizian themes and for how we should read Leibniz and other philosophers of the sixteenth and later centuries as 'modem' philosophers. Leibniz began his philosophical career more than 300 years ago, a fact that shapes fundamentally my attempt in the pages that follow to come to terms now with the texts that he left us. Leibniz's did not do philosophy in a way wholly congenial to twentieth century philosophical methodologies, especially those that have enjoyed some prominence in recent Anglo-American philosophy. Moreover, as we shall see, Leibniz is not a modem philosopher, when 'modem' is understood to mean making a sharp break with medieval philosophy. Indeed, I shall argue, scholars should discard such terms as 'modem' from historical philosophical scholarship, so that old texts can be allowed to remain old - to stand on their own in and from times now long past.

Legendary since his own time as a universal genius, Gottfried Wilhelm Leibniz (1646-1716) contributed significantly to almost every branch of learning, from mathematics to ecumenical theology. 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. Leibniz's writings in metaphysics 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 theory of monads).

Daniel Garber presents an illuminating study of Leibniz's conception of the physical world. Leibniz's commentators usually begin with monads, mind-like simple substances, the ultimate building-blocks of the Monadology. But Leibniz's apparently idealist metaphysics is very puzzling: how can any sensible person think that the world is made up of tiny minds? In this book, Garber tries to make Leibniz's thought intelligible by focusing instead on his notion of body. Beginning with Leibniz's earliest writings, he shows how Leibniz starts as a Hobbesian with a robust sense of the physical world, and how, step by step, he advances to the monadological metaphysics of his later years. Much of the book's focus is on Leibniz's middle years, where the fundamental constituents of the world are corporeal substances, unities of matter and form understood on the model of animals. For Garber monads only enter fairly late in Leibniz's career, and when they enter, he argues, they do not displace bodies but complement them. In the end, though, Garber argues that Leibniz never works out the relation between the world of monads and the world of bodies to his own satisfaction: at the time of his death, his philosophy is still a work in progress.

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.

This anthology is about the signal change in Leibniz’s metaphysics with his explicit adoption of substantial forms in 1678-79. This change can either be seen as a moment of discontinuity with his metaphysics of maturity or as a moment of continuity, such as a passage to the metaphysics from his last years. Between the end of his sejour at Paris (November 1676) and the first part of the Hanover period, Leibniz reformed his dynamics and began to use the theory of corporeal substance. This book explores a very important part of the philosophical work of the young Leibniz. Expertise from around the globe is collated here, including Daniel Garber’s work based on the recent publication of Leibniz's correspondence from the late 1690s, examining how the theory of monads developed during these crucial years. Richard Arthur argues that the introduction of substantial forms, reinterpreted as enduring primitive forces of action in each corporeal substance, allows Leibniz to found the reality of the phenomena of motion in force and thus avoid reducing motion to a mere appearance. Amongst other themes covered in this book, Pauline Phemister’s paper investigates Leibniz’s views on animals and plants, highlighting changes, modifications and elaborations over time of Leibniz’s views and supporting arguments and paying particular attention to his claim that the future is already contained in the seeds of living things. The editor, Adrian Nita, contributes a paper on the continuity or discontinuity of Leibniz’s work on the question of the unity and identity of substance from the perspective of the relation with soul (anima) and mind (mens).

Philosophy in the sixteenth through eighteenth centuries has traditionally been characterized as being primarily concerned with epistemological issues. This book is not intended to overturn this characterization but rather to balance it through an examination of equally important metaphysical, or ontological, positions held, explicitly or implicitly, by philosophers in this period. Major philosophers whose views are discussed in this book include Descartes, Malebranche, Spinoza, Locke, Berkeley, Hume, Leibniz, Wolff, and Kant. In addition, the contributors of minor Cartesians, especially Regis and Desgabets, are analyzed in a separate chapter. Although the views of early modern philosophers on individuation and identity have been discussed before, these discussions have usually been treated as asides in a larger context. This book is the first to concentrate on the problems of individuation and identity in early modern philosophy and to trace their philosophical development through the period in a coherent way.

The study offers a new account of one of the central topics of Leibniz's philosophy: substance. It brings to light the metaphysical foundations of Leibniz's notion of substance and shows - in opposition to many leading commentators - that his treatment of it is governed by clear standards of significance rooted in his broader metaphysical position. Starting from Leibniz's general theory of definition - founded on his views concerning the science of metaphysics - the author identifies the set of basic defining features of substance for Leibniz and then provides a detailed analysis and interpretation of these features. A foundational role is given to a group of texts from the 1680's in which Leibniz provides conceptual analyses of the most general items of reality.

With the publication of French Philosophy of the Sixties, Alain Renaut and Luc Ferry in 1985 launched their famous critique against canonical figures such as Foucault, Derrida, and Lacan, bringing under rigorous scrutiny the entire post-structuralist project that had dominated Western intellectual life for over two decades. Their goal was to defend the accomplishments of liberal democracy, particularly in terms of basic human rights, and to trace the reigning philosophers' distrust of liberalism to an "antihumanism" inherited mainly from Heidegger. In The Era of the Individual, widely hailed as Renaut's magnum opus, the author explores the most salient feature of post-structuralism: the elimination of the human subject. At the root of this thinking lies the belief that humans cannot know or control their basic natures, a premise that led to Heidegger's distrust of an individualistic, capitalist modern society and that allied him briefly with Hitler's National Socialist Party. While acknowledging some of Heidegger's misgivings toward modernity as legitimate, Renaut argues that it is nevertheless wrong to equate modernity with the triumph of individualism. Here he distinguishes between individualism and subjectivity and, by offering a history of the two, powerfully redirects the course of current thinking away from potentially dangerous, reductionist views of humanity. Renaut argues that modern philosophy contains within itself two opposed ways of conceiving the human person. The first, which has its roots in Descartes and Kant, views human beings as subjects capable of arriving at universal moral judgments. The second, stemming from Leibniz, Hegel, and Nietzsche, presents human beings as independent individuals sharing nothing with others. In a careful recounting of this philosophical tradition, Renaut shows the resonances of these traditions in more recent philosophers such as Heidegger and in the social anthropology of Louis Dumont. Renaut's distinction between individualism and subjectivity has become an important issue for young thinkers dissatisfied with the intellectual tradition originating in Nietzsche and Heidegger. Moreover, his proclivity toward the Kantian tradition, combined with his insights into the shortcomings of modernity, will interest anyone concerned about today's shifting cultural attitudes toward liberalism.
