Boyce Gibson Professor of Philosophy Graham Priest

Along the way, the book explains the basic ideas of formal logic in simple, non-technical terms, as well as the philosophical pressures to which these have responded. This is a book for anyone who has ever been puzzled by a piece of reasoning."--BOOK JACKET.

Logic: A Very Short Introduction

سلسلة مقدمة قصيرة عن المنطق

Graham Priest presents an expanded edition of his exploration of the nature and limits of thought. Embracing contradiction and challenging traditional logic, he engages with issues across philosophical borders, from the historical to the modern, Eastern to Western, continental to analytic.

Beyond the Limits of Thought

Written with passion by experts in their field, concise and accessible books feature color illustrations and explore a sweeping range of topics, including history, philosophy, religion, mathematics and more.

A Brief Insight

Logic

Priest advocates and defends the view that there are true contradictions (dialetheism), a perspective that flies in the face of orthodoxy in Western philosophy since Aristole and remains at the centre of philosophical debate. This edition contains the author's reflections on developments since 1987.

In Contradiction

"Towards Non-Being presents an account of the semantics of intentional verbs such as 'believes', 'fears', 'seeks', and 'imagines'. It tackles problems concerning intentional states which are often brushed under the carpet, such as their failure to be closed under deducibility. Drawing on the noneist work of the late Richard Routley (Sylvan), the book proceeds in terms of objects that may be existent or non-existent, at worlds that may either be possible or impossible. Since Russell, non-existent objects have had a bad press in Western philosophy. The book mounts a full-scale defence, and in the process, offers an account of both fictional and mathematical objects as non-existent."--Publisher's description.

The Logic and Metaphysics of Intentionality

Towards Non-being

Markus Gabriel

Is it possible for reality as a whole to be part of itself? Can the world appear within itself without thereby undermining the consistency of our thought and knowledge-claims concerning more local matters of fact? This is a question on which Markus Gabriel and Graham Priest disagree. Gabriel argues that the world cannot exist precisely because it is understood to be an absolutely totality. Priest responds by developing a special form of mereology according to which reality is a single all-encompassing whole, everything, which counts itself among its denizens. Their disagreement results in a debate about everything and nothing: Gabriel argues that we experience nothingness once we overcome our urge to contain reality in an all-encompassing thought, whereas Priest develops an account of nothing according to which it is the ground of absolutely everything. A debate about everything and nothing, but also a reflection on the very possibility of metaphysics.

Everything and Nothing

Jay L. Garfield

Yasuo Deguchi

Robert H. Sharf

Typically, in the Western philosophical tradition, the presence of paradox and contradictions is taken to signal the failure or refutation of a theory or line of thinking. This aversion to paradox rests on the commitment-whether implicit or explicit-to the view that reality must be consistent. In What Can't be Said, Yasuo Deguchi, Jay L. Garfield, Graham Priest, and Robert H. Sharf extend their earlier arguments that the discovery of paradox and contradiction can deepen rather than disprove a philosophical position, and confirm these ideas in the context of East Asian philosophy. They claim that, unlike most Western philosophers, many East Asian philosophers embraced paradox, and provide textual evidence for this claim. Examining two classical Daoist texts, the Daodejing and the Zhaungzi, as well as the trajectory of Buddhism in East Asia, including works from the Sanlun, Tiantai, Chan, and Zen traditions and culminating with the Kyoto school of philosophy, they argue that these philosophers' commitment to paradox reflects an understanding of reality as inherently paradoxical, revealing significant philosophical insights.

What Can't be Said

Towards Non-Being presents an account of the semantics of intentional language - verbs such as 'believes', 'fears', 'seeks', 'imagines'. Graham Priest's account tackles problems concerning intentional states which are often brushed under the carpet in discussions of intentionality, such as their failure to be closed under deducibility. Drawing on the work of the late Richard Routley (Sylvan), it proceeds in terms of objects that may be either existent or non-existent, atworlds that may be either possible or impossible. Since Russell, non-existent objects have had a bad press in Western philosophy; Priest mounts a full-scale defence. In the process, he offers an account of both fictional and mathematical objects as non-existent.The book will be of central interest to anyone who is concerned with intentionality in the philosophy of mind or philosophy of language, the metaphysics of existence and identity, the philosophy or fiction, the philosophy of mathematics, or cognitive representation in AI.

This updated second edition adds ten new chapters to the original eight. These further develop the ideas of the first edition, reply to critics, and explore new areas of relevance. New topics covered include: conceivability, realism/antirealism concerning non-existent objects, self-deception, and the verb to be.

This book is an introduction to non-classical propositional logics. It brings together for the first time in a textbook a range of topics in logic, many of them of relatively recent origin, including modal, conditional, intuitionist, many-valued, paraconsistent, relevant and fuzzy logics. The material is unified by the underlying theme of world-semantics. All of the topics are explained clearly and accessibly, using devices such as tableaux proofs, and their relation to current philosophical issues and debates is discussed. Students with a basic understanding of classical logic will find this an invaluable introduction to an area that has become of central importance in both logic and philosophy, but which, until now, could be studied only through the research literature. It will interest those studying logic, those who need to know about non-classical logics because of their philosophical importance, and, more widely, readers working in mathematics and computer science.

An Introduction to Non-Classical Logic

This second and extended edition of Priest's classic includes new chapters on Heidegger and Nagarjuna, as well as reflections on reactions to the first edition. Praise for previous edition: "a splendid tour de force, one which should be read by every philosopher..."--Philosophical Quarterly "[H]ighly entertaining and provocative...an engaging and instructive tour through some of the most perplexing features of our own conceptual finitude..."--TLS

This revised and considerably expanded 2nd edition brings together a wide range of topics, including modal, tense, conditional, intuitionist, many-valued, paraconsistent, relevant, and fuzzy logics. Part 1, on propositional logic, is the old Introduction, but contains much new material. Part 2 is entirely new, and covers quantification and identity for all the logics in Part 1. The material is unified by the underlying theme of world semantics. All of the topics are explained clearly using devices such as tableau proofs, and their relation to current philosophical issues and debates are discussed. Students with a basic understanding of classical logic will find this book an invaluable introduction to an area that has become of central importance in both logic and philosophy. It will also interest people working in mathematics and computer science who wish to know about the area.

This is the first substantial academic book to lay out the philosophical terrain within the study of the martial arts and to explore the significance of this fascinating subject for contemporary philosophy. The book is divided into three sections. The first section concerns what philosophical reflection can teach us about the martial arts, and especially the nature and value of its practice. The second section deals with the other direction of the dialectical interplay between philosophy and the martial arts: how the martial arts can inform philosophical issues important in their own right. Finally, because many of the notable martial arts are of Asian origin, there are particularly close links between the arts and Asian philosophies – and Buddhism in particular – and therefore the last section is devoted to this topic. The essays in this collection deal with a wide range of philosophical issues: normative ethics, meta-ethics, aesthetics, phenomenology, the philosophy of mind, Ancient Greek and Buddhist thought. By demonstrating the very real nature of the engagement between the martial arts and philosophy, this book is essential reading for any serious student or scholar with an interest in the martial arts, Eastern philosophy, the philosophy of sport, or the study of physical culture.

Philosophy and the Martial Arts

David Lewis's untimely death on 14 October 2001 deprived the philosophical community of one of the outstanding philosophers of the 20th century. As many obituaries remarked, Lewis has an undeniable place in the history of analytical philosophy. His work defines much of the current agenda in metaphysics, philosophical logic, and the philosophy of mind and language. This volume, an expanded edition of a special issue of the Australasian Journal of Philosophy, covers many of the topics for which Lewis was well known, including possible worlds, counterpart theory, vagueness, knowledge, probability, essence, fiction, laws, conditionals, desire and belief, and truth. Many of the papers are by very established philosophers; others are by younger scholars including many he taught. The volume also includes Lewis's Jack Smart Lecture at the Australian National University, How Many Lives has Schrödinger's Cat?, published here for the first time. Lewisian Themes will be an invaluable resource for anyone studying Lewis's work and a major contribution to the many topics that he mastered.

The Philosophy of David K. Lewis

Lewisian Themes

Ricki Bliss

Reality is a rather large place. It contains protons, economies, headaches, sentences, smiles, asteroids, crimes, and numbers, and very many other things. Much of the content of our reality appears to depend on other of its content. Economies, for example, appear to depend upon people and the way they behave, amongst other things. Some of the content of our reality also appears to be, in some significant sense, more important than other of its content. Whilst none of us would wish to deny the very important role that economies play in our lives, most of us would agree that without matter arranged certain ways in space, for example, there could be no economies in the first place. Very many contemporary philosophers are concerned with how exactly we are to fill in the details of this view. What they are inclined to agree on is that reality has an over-arching hierarchical structure ordered by relations of metaphysical dependence, where chains of entities ordered by those dependence relations terminate in something fundamental. It is also commonly taken for granted that what those dependence chains terminate in is merely contingently existent - those things could have failed to exist - and consistent - they have no contradictory properties. This volume brings together fifteen essays from leading and emerging scholars that address these core, yet often under-explored, commitments.

Essays in Fundamentality

Reality and its Structure

Graham Priest presents an original exploration of philosophical questions concerning the one and the many. He covers a wide range of issues in metaphysics—including unity, identity, grounding, mereology, universals, being, intentionality, and nothingness—and deploys the techniques of paraconsistent logic in order to offer a radically new treatment of unity. Priest brings together traditions of Western and Asian thought that are usually kept separate in academic philosophy: he draws on ideas from Plato, Heidegger, and Nagarjuna, among other philosophers.

Being an Investigation into the Unity of Reality and of its Parts, including the Singular Object which is Nothingness

"Paradox drives a good deal of philosophy in every tradition. In the Indian and Western traditions, there is a tendency among many (but not all) philosophers to run from contradiction and paradox. If and when a contradiction appears in a theory, it is regarded as a sure sign that something has gone amiss. This aversion to paradox commits them, knowingly or not, to the view that reality must be consistent. In East Asia, however, philosophers have reacted to paradox differently. Many East Asian philosophers-both in the Daoist and the Buddhist traditions-have openly embraced paradox. They have taken compelling arguments for contradictory positions to suggest that the world is-at least in some respects, and often in very deep respects-inconsistent, and that our best theories of the world will therefore be inconsistent. This book is an initial survey of the writings of some influential East Asian thinkers who were committed to paradox, and for good reason. Their acceptance of contradiction allowed them to develop important insights that evaded those who consider paradox out of bounds"--

What Can't Be Said

Logic is often perceived as having little to do with the rest of philosophy, and even less to do with real life. In this lively and accessible introduction, Graham Priest shows how wrong this conception is. He explores the philosophical roots of the subject, explaining how modern formal logic deals with issues ranging from the existence of God and the reality of time to paradoxes of probability and decision theory. Along the way, the basics of formal logic are explained in simple, non-technical terms, showing that logic is a powerful and exciting part of modern philosophy. In this new edition Graham Priest expands his discussion to cover the subjects of algorithms and axioms, and proofs in mathematics. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.
