The Law of Non-Contradiction has been high orthodoxy in Western philosophy since Aristotle. The so-called Law has been the subject of radical challenge in recent years by dialetheism, the view that some contradictions are indeed true. Many philosophers have taken the Law to be central to many of our most important philosophical concepts. In Doubt Truth to be a Liar, Graham Priest mounts the case against this. Starting with an analysis of Aristotle on the Law, he discusses the nature of truth, or rationality, or negation, and of logic itself, and argues that the Law is inessential to all of these things. The book takes off from Priest's earlier book, In Contradiction (a second edition of which is also published by OUP), developing its themes largely without recourse to formal logic. The book is required reading for anyone who wishes to understand dialetheism; (especially) for anyone who wishes to continue to endorse the old Aristotelian orthodoxy; and more generally, for anyone who wishes to understand the role that contradiction plays in our thinking.

In Contradiction advocates and defends the view that _ there are true contradictions (dialetheism), a view that _ flies in the face of orthodoxy in Western philosophy since_ Aristotle. The book has been at the centre of the _ controversies surrounding dialetheism ever since its first_ publication in 1987. This second edition of the book _ substantially expands upon the original in various ways, and also contains the author's reflections on developments over the last two decades. Further aspects of dialetheism are _ discussed in the companion volume, Doubt Truth to be a _ Liar, also published by Oxford University Press in 2006.

Dialetheism is the view that some contradictions are true. This is a view which runs against orthodoxy in logic and metaphysics since Aristotle, and has implications for many of the core notions of philosophy. Doubt Truth to Be a Liar explores these implications for truth, rationality, negation, and the nature of logic, and develops further the defence of dialetheism first mounted in Priest's In Contradiction, a second edition of which is also available.

Graham Priest presents an expanded edition of his exploration of the nature and limits of thought. Embracing contradiction and challenging traditional logic, Priest engages with issues across philosophical borders, from the historical to the modern, from Eastern to Western, and from the continental to the analytic. He has added new chapters on European and Indian philosophy, and reflections on responses to the book.

Graham Priest presents a new, expanded edition of his highly original exploration of the nature and limits of thought. Drawing on recent developments in the field of logic, Priest shows that the description of such limits leads to contradiction, and argues that these contradictions are in fact true. Beginning with an analysis of the way in which these limits arise in pre-Kantian philosophy, Priest goes on to illustrate how the nature of these limits was theorized by Kant and Hegel. He offers new interpretations of Berkeley's master argument for idealism and Kant on the antinomies. He explores the paradoxes of self-reference, and provides a unified account of the structure of such paradoxes. The book goes on to trace the theme of the limits of thought in modern philosophy of language, including discussions of the ideas of Wittgenstein and Derrida. The second edition includes new chapters on Heidegger and Nagarjuna, as well as reflections on reactions to the first edition. This clear, provocative, and systematic work offers a radically different approach to philosophy and logic.
