This volume tells the story of the legacy and impact of the great German polymath Gottfried Wilhelm Leibniz (1646-1716). Leibniz made significant contributions to many areas, including philosophy, mathematics, political and social theory, theology, and various sciences. The essays in this volume explores the effects of Leibniz's profound insights on subsequent generations of thinkers by tracing the ways in which his ideas have been defended and developed in the three centuries since his death. Each of the 11 essays is concerned with Leibniz's legacy and impact in a particular area, and between them they show not just the depth of Leibniz's talents but also the extent to which he shaped the various domains to which he contributed, and in some cases continues to shape them today. With essays written by experts such as Nicholas Jolley, Pauline Phemister, and Philip Beeley, this volume is essential reading not just for students of Leibniz but also for those who wish to understand the game-changing impact made by one of history's true universal geniuses.

Originally published in 1991, this volume examines Hegel's political philosophy from the perspective of his argument for constitutional monarchy. It offers an interpretation of Hegelian theory that is relevant for the understanding of modern republican constitutions. Modern republican theories are assessed together with those of Plato, Kant and Marx in order to put Hegel's model to the most rigorous test. The arguments are based on fresh analysis of Hegel's system and on new translations of key passages in Hegel's text.

Originally published in 1972, Medieval Logic and Metaphysics shows how formal logic can be used in the clarification of philosophical problems. An elementary exposition of Lesniewski's Onotology, an important system of contemporary logic, is followed by studies of central philosophical themes such as Negation and Non-being, Essence and Existence, Meaning and Reference, Part and Whole. Philosophers and theologians discussed include St Anselm, St Thomas Aquinas, Abelard, Ockham, Scotus, Hume and Russell.

Originally published in 1994, The Incommensurability Thesis is a critical study of the Incommensurability Thesis of Thomas Kuhn and Paul Feyerabend. The book examines the theory that different scientific theories may be incommensurable because of conceptual variance. The book presents a critique of the thesis and examines and discusses the arguments for the theory, acknowledging and debating the opposing views of other theorists. The book provides a comprehensive and detailed discussion of the incommensurability thesis.

Ever since Saul Kripke and others developed a semantic interpretation for modal logic, 'possible worlds' has been a much debated issue in contemporary metaphysics. To propose the idea of a possible world that differs in some way from our actual world - for example a world where the grass is red or where no people exist - can help us to analyse and understand a wide range of philosophical concepts, such as counterfactuals, properties, modality, and of course, the notions of possibility and necessity. This book examines the ways in which possible worlds have been used as a framework for considering problems in logic and argument analysis. The book begins with a non-technical introduction to the basic ideas of modal logic in terms of Kripke's possible worlds and then moves on to a discussion of 'possible for' and 'possible that'. The central chapters examine questions of meaning, epistemic possibility, temporal logic, metaphysics, and impossibility. Girle also investigates how the idea of a possible world can be put to use in different areas of philosophy, the problems it may raise, and the benefits that can be gained.

This volume provides a comprehensive collection of classic and contemporary readings in the philosophy of logic. The selections include some of the most important, technically exact, yet lucid and readable expositions of central concepts and controversies in philosophical logic. Areas of coverage include classical logic, truth, propositions and meaning, quantifiers and quantificational theory, validity, inference and entailment, and modality, intensionality and propositional attitude.

Since the articles are written from a variety of perspectives, the reader is able to critically assess the background and current trends in philosophical applications of symbolic logic. The volume also examines the limitations of classical and nonstandard logics.

The book complements "Philosophy of Mathematics: An Anthology" and "A Companion to Philosophical Logic, "also edited by Dale Jacquette.

Originally published in 1990. This study was first written in 1965 when interest in Leibniz was intensifying. The book looks in detail at the doctrine of necessity - that necessary truths are those derivable from the principle of identity by the substitution of definitions. It first considers views of philosophic predecessors, relating Leibniz' doctrine to Aristotle and Hobbes among others. The second section examines the conflict between his reductionistic and formalistic views and the opposing intuitionism and anti-reductionism of Descartes and Locke. The author critically examines the theory of necessity, including Leibniz's arguments against the views of Hobbes and Locke, concluding with distinctions between necessary and contingent truths.

This new edition includes three new chapters, updating the book to take into account developments in the area over the past fifteen years.

Nyana is the most rational and logical of all the classical Indian philosophical systems. In the study of Nyana philosophy, Karikavali with its commentary Muktavali, both by Visvanatha Nyayapancanana, with the commentaries Dinakari and Ramarudri, have been of decisive significance for the last few centuries as advanced introductions to this subject. The present work concentrates on inference (anumana) in Karikavali, Muktavali and Dinakari, carefully divided into significant units according to the subject, and translates and interprets them. Its commentary makes use of the primary interpretation in Sanskrit contained especially in the Ramarudri and Subodhini. The book begins with the Sanskrit texts of Karikavali and Muktavali; followed by English translation of these texts. Next is given the Sanskrit text of Dinakari which comments on the first two texts, followed by its English translation. Lastly, the book contains a commentary on all the texts included.

Possible Worlds presents the first up-to-date and comprehensive examination of one of the most important topics in metaphysics. John Divers considers the prevalent philosophical positions, including realism, antirealism and the work of important writers on possible worlds such as David Lewis, evaluating them in detail.

First published in 1998, this volume has its origin in a meeting that was held in Santiago de Compostela University, Santiago de Compostela (Spain) in January 1996. The meeting was organized by the Department of Logic and Philosophy of Science in cooperation with the Association for Logic, Methodology and Philosophy of Science in Spain. Within analytical philosophy issues such as the definability of truth, its semantic relevance, its role in the distinction between formal and natural languages, the status of truth-bearers or in its case of truth-makers, have become a crossroads in the studies of logic, philosophy of science, philosophy of language, philosophy of mind, epistemology and ontology. Thus, in spite of what the title Truth in Perspective may suggest to the reader at first, the present volume is not only - though it is also a presentation of different theories or conceptions of truth. Most of the book presents a vision of different groups of philosophical questions in which the issue of truth appears embedded together with other related themes, from different points of view.

This work is a contribution to certain aspects of idealistic philosophy. It is a comparative study, yet it is not a comparison for the sake of comparison. This book examines the supra-rational Absolutism of the West developed under the Hegelian influence, and in the light of the criticisms shows the peculiar character of the Advaita Vedanta of Sankara. It is therefore not a mere exposition, but a criticism and construction. The discussions are not cosmological, but epistemological and metaphysical, approached from the side of logic. The work may also be viewed as a reorientation of Sankara's system. It places Sankara's philosophy in line with the idealistic philosophies of the West, so that we can understand the peculiarities of the former in terms of the latter. It thus discovers or brings into clearer light the guiding principle of Sankara's thought. It brings out the full significance of the principles of non-contradiction applied by Sankara as a test of truth and reality, and shows its difference from the same principle as understood by Hegel and the Hegelians. The aim of this work is to attempt at laying the metaphysical foundation of the logic of supra-rational Absolutism, the interpretation of Advaita is based mostly on polemical works.

This text examines the boundary between logic and philosophy in Kant and Hegel. Through a detailed analysis of 'quantity', it highlights the different ways Kant and Hegel handle this boundary. Kant is consistent in maintaining this boundary, but Hegel erases it and in the process transforms both logic and philosophy.

In this book, Bradley Armour-Garb and James A. Woodbridge distinguish various species of fictionalism, locating and defending their own version of philosophical fictionalism. Addressing semantic and philosophical puzzles that arise from ordinary language, they consider such issues as the problem of non-being, plural identity claims, mental-attitude ascriptions, meaning attributions, and truth-talk. They consider 'deflationism about truth', explaining why deflationists should be fictionalists, and show how their philosophical fictionalist account of truth-talk underwrites a dissolution of the Liar Paradox and its kin. They further explore the semantic notions of reference and predicate-satisfaction, showing how philosophical fictionalism can also resolve puzzles that these notions appear to present. Their critical examination of fictionalist approaches in philosophy, together with the development and application of their own brand of philosophical fictionalism, will be of great interest to scholars and upper-level students of philosophy of language, metaphysics, philosophical logic, philosophy of mind, epistemology, and linguistics.

This book, a rich collection authored by rhetorical scholars, unpacks how rhetoric contributes to argumentation studies. It begins with an introduction that identifies defining features of a rhetorical approach to argumentation which has several corollaries, including the special status of argumentation about action, the condition of uncertainty and the necessity of securing adherence from an audience. Chapters explore topics such as the properties of argumentation in the realm of rhetoric, the use of presentational devices, the role of rhetoric in the evolving formation of public morality, conditions for democratic argumentation, argument pedagogy, rhetorical insights into science communication, and other features within the realm of rhetorical argumentation. This book is relevant to students and researchers in linguistics, rhetoric, philosophy, argumentation studies, and communication studies.

Argumentation, which can be abstractly defined as the interaction of different arguments for and against some conclusion, is an important skill to learn for everyday life, law, science, politics, and business. The best way to learn it is to try it out on real instances of arguments found in everyday conversational exchanges and legal argumentation. The introductory chapter of this book gives a clear general idea of what the methods of argumentation are and how they work as tools that can be used to analyze arguments. Each subsequent chapter then applies these methods to a leading problem of argumentation. Today the field of computing has embraced argumentation as a paradigm for research in artificial intelligence and multi-agent systems. Another purpose of this book is to present and refine tools and techniques from computing as components of the methods that can be handily used by scholars in other fields.

Morton Schoolman explores what makes humankind capable of genocide in this fascinating interpretation of Horkheimer and Adorno. He recasts their views on diversity and individuality before and after the Holocaust, as well as re-examining Nietzsche and even Whitman and Tocqueville. He argues that the sensibility the critical theorists argued for is actually nurtured in a democracy, and concludes that to avoid the possibility of genocide people must also change the way they feel, and cultivate an aesthetic sensibility.

Our finances, politics, media, opportunities, information, shopping and knowledge production are mediated through algorithms and their statistical approaches to knowledge; increasingly, these methods form the organizational backbone of contemporary capitalism. Revolutionary Mathematics traces the revolution in statistics and probability that has quietly underwritten the explosion of machine learning, big data and predictive algorithms that now decide many aspects of our lives. Exploring shifts in the philosophical understanding of probability in the late twentieth century, Joque shows how this was not merely a technical change but a wholesale philosophical transformation in the production of knowledge and the extraction of value. This book provides a new and unique perspective on the dangers of allowing artificial intelligence and big data to manage society. It is essential reading for those who want to understand the underlying ideological and philosophical changes that have fueled the rise of algorithms and convinced so many to blindly trust their outputs, reshaping our current political and economic situation.
