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.
