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)

Many people find themselves dissatisfied with recent linguistic philosophy, and yet know that language has always mattered deeply to philosophy and must in some sense continue to do so. Ian Hacking considers here some dozen case studies in the history of philosophy to show the different ways in which language has been important, and the consequences for the development of the subject. There are chapters on, among others, Hobbes, Berkeley, Russell, Ayer, Wittgenstein, Chomsky, Feyerabend and Davidson. Dr Hacking ends by (...) speculating about the directions in which philosophy and the study of language seem likely to go. The book will provide students with a stimulating, broad survey of problems in the theory of meaning and the development of philosophy, particularly in this century. The topics treated in the philosophy of language are among the central, current concerns of philosophers, and the historical framework makes it possible to introduce concretely and intelligibly all the main theoretical issues.

Hobbes and Wallis's "battle of the books" illuminates the intimate relationship between science and crucial seventeenth-century debates over the limits of sovereign power and the existence of God.

Gonzalo Rodriguez-Pereyra offers a fresh philosophical account of properties. How is it that two different things (such as two red roses) can share the same property (redness)? According to resemblance nominalism, things have their properties in virtue of resembling other things. This unfashionable view is championed with clarity and rigor.

The notion of signification is an important part of Hobbes's philosophy of language. It also has broader relevance, as Hobbes argues that key terms used by his opponents are insignificant. However Hobbes's talk about names' signification is puzzling, as he appears to have advocated conflicting views. This paper argues that Hobbes endorsed two different views of names' signification in two different contexts. When stating his theoretical views about signification, Hobbes claimed that names signify ideas. Elsewhere he talked as if words (...) signified the things they named. Seeing this does not just resolve a puzzle about Hobbes's statements about signification. It also helps us to understand how Hobbes's arguments about insignificant speech work. With one important exception, they depend on the view that names signify things, not on Hobbes's stated theory that words signify ideas. The paper concludes by discussing whether arguments about insignificant speech can provide independent support for Hobbes's views about other issues, such as materialism. (shrink)

I consider Leibniz's thoughts about Hobbes's materialism, focusing on his less-discussed later thoughts about the topic. Leibniz understood Hobbes to have argued for his materialism from his imagistic theory of ideas. Leibniz offered several criticisms of this argument and the resulting materialism itself. Several of these criticisms occur in texts in which Leibniz was engaging with the generation of British philosophers after Hobbes. Of particular interest is Leibniz's correspondence with Damaris Masham. Leibniz may have been trying to communicate with Locke, (...) but ended up discussing Masham's version of the argument for materialism that Leibniz attributed to Hobbes. (shrink)

Science Without Numbers caused a stir in 1980, with its bold nominalist approach to the philosophy of mathematics and science. It has been unavailable for twenty years and is now reissued in a revised edition with a substantial new preface presenting the author's current views and responses to the issues raised in subsequent debate.

In the early years of the eighteenth century Leibniz had several interactions with John Toland. These included, from 1702 to 1704, discussions of materialism. Those discussions culminated with the consideration of Toland's 1704 Letters to Serena, where Toland argued that matter is necessarily active. In this paper I argue for two main theses about this exchange and its consequences for our wider understanding. The first is that, despite many claims that Toland was at the time of Letters to Serena a (...) Spinozist, we can make better sense of him as a sort of Hobbesian materialist. The second main point concerns reasons for materialism, and in particular a story Locke tells in the Essay about materialists' motives. Toland defends his materialism by arguing that matter is active, and argues that matter is active by using a conceivability argument. But this is not the crude conceivability argument that Locke suggests motivates materialists. This (together with reflecting on some of Hobbes's arguments) suggests that we might well tell a Lockean story about reasons for early modern materialism, but not Locke's story. (shrink)

Volumes I and II provided a completely new translation of the philosophical works of Descartes, based on the best available Latin and French texts. Volume III contains 207 of Descartes' letters, over half of which have previously not been translated into English. It incorporates, in its entirety, Anthony Kenny's celebrated translation of selected philosophical letters, first published in 1970. In conjunction with Volumes I and II it is designed to meet the widespread demand for a comprehensive, authoritative and accurate edition (...) of Descartes' philosophical writings in clear and readable modern English.

I argue that Hobbes isn't really a materialist in the early 1640s (in, e.g., the Third Objections to Descartes's Meditations). That is, he doesn't assert that bodies are the only substances. However, he does think that bodies are the only substances we can think about using imagistic ideas.

Leibniz repeatedly daims to refute "Hobbes' doctrine of arbitrary truth". I argue against several recent expositors of Hobbes that Hobbes' view comes to nothing more scandalous than "nominalism" about kind terms. Although some have recognized that it is this thesis which Leibniz claims to refute, his argument has not been correctly understood. I maintain that the argument rests upon Leibniz' theory of signs and his account of concepts. In brief, Leibniz argues that concepts have structures which correspond to structures of (...) (possible) things; thus, kinds are independent of language and truth is independent of arbitrary convention. (shrink)

Noel Malcolm, one of the world's leading experts on Thomas Hobbes, presents a set of extended essays on a wide variety of aspects of the life and work of this giant of early modern thought. Malcolm offers a succinct introduction to Hobbes's life and thought, as a foundation for his discussion of such topics as his political philosophy, his theory of international relations, the development of his mechanistic world-view, and his subversive Biblical criticism. Several of the essays pay special attention (...) to the European dimensions of Hobbes's life, his sources and his influence; the longest surveys the entire European reception of his work from the 1640s to the 1750s. All the essays are based on a deep knowledge of primary sources, and many present striking new discoveries about Hobbes's life, his manuscripts, and the printing history of his works. Aspects of Hobbes will be essential reading not only for Hobbes specialists, but also for all those interested in seventeenth-century intellectual history more generally, both British and European.

Leibniz' formula 'plusquam nominalis' is not applicable to Hobbes' theory of truth. Nor do his remarks on the relationship between thought and reality or between nomenclature and reality lead to ultranominalism. That would be the case only in his new definition of the relationship between name and concept; and in his thesis 'there is nothing universal but names' there is indeed a rejection of the Ockhamistic tradition of realistic conceptualism' (Boehner). Hobbes, however, does not succeed in constructing his logic without (...) the help of general concepts. This disparity between the programm and its realization can perhaps best be characterized as a 'dissimulated conceptualism'. (shrink)

These essays are the fruit of many years' research by one of the world's leading Hobbes scholars. Noel Malcolm offers not only succinct introductions to Hobbes 's life and thought, but also path-breaking studies of many different aspects of his political philosophy, his scientific and religious theories, his relations with his contemporaries, the sources of his ideas, the printing history of his works, and his influence on European thought.
