The Law Of Non-Contradiction: New Philosophical Essays by Graham Priest – A Critical Examination of a Foundational Logic

Introduction

The Law of Non-Contradiction has stood as one of the most enduring pillars of Western logic since Aristotle first articulated it in his Metaphysics. But what happens when this seemingly unshakeable principle is put on trial? The Law Of Non-Contradiction: New Philosophical Essays, edited by the renowned logician Graham Priest, brings together twenty-three of the world's foremost thinkers to question, defend, and reimagine this foundational law. This hardcover volume from OUP Oxford is an essential resource for anyone serious about the philosophy of logic, offering a rigorous yet accessible examination of whether contradictions can ever be true.

Book Overview

This collection represents the most comprehensive investigation into the Law of Non-Contradiction ever assembled. Rather than treating the law as an inviolable dogma, the essays invite readers into a dynamic debate: What does the law actually assert? Can it be proven? Are there genuine counterexamples, such as the Liar Paradox? The book explores both classical defences and radical challenges, including the controversial 'dialetheic' view that some contradictions are true. With contributions from leading scholars, this volume charts the very frontiers of logical inquiry.

Key Highlights

• Comprehensive Debate: Features 23 original essays from top philosophers and logicians worldwide.
• Balanced Perspective: Presents arguments both for and against the law, allowing readers to form their own conclusions.
• Cutting-Edge Topics: Engages with the Liar Paradox, dialetheism, paraconsistent logic, and the limits of logical principles.
• Authoritative Editorship: Edited by Graham Priest, one of the most influential figures in contemporary logic and metaphysics.
• Rigorous Yet Accessible: Written for advanced students and researchers, but with clarity that invites dedicated non-specialists.

Inside the Book

The volume is structured to guide the reader through the central issues. It begins with foundational questions: How should the Law of Non-Contradiction be formulated? Is it a metaphysical, logical, or semantic principle? From there, the essays move to arguments for the law—including transcendental and pragmatic defences—before turning to powerful critiques. Key sections examine the Liar Paradox and its implications, the possibility of true contradictions (dialetheism), and the methodological challenges that arise when we question logical laws. Each essay is self-contained yet contributes to an overarching dialogue.
