Doubt thou the stars are fire;
Doubt that the sun doth move;
Doubt truth to be a liar;
But never doubt I love.
(Hamlet, ii. ii. 115)

In Contradiction, which was first published in 1987, provided a sustained argument for
and defence of dialetheism. My thoughts on the topic have continued to evolve since
that time, however. A general discussion of the evolution can be found in the second
edition of that book, which is a companion volume to this one. One particular area of
development concerns the implications of dialetheism for certain key philosophical
notions, such as truth and rationality—and vice versa. That is what this book is about.
The book draws on papers that I have published since 1987. In particular, it draws
on the following material, which, however, has been refashioned in some places—at
some points substantially—in the cause of coherence:

Chapter 1: ‘To Be and Not to Be—that is the Answer: Aristotle on the
Law of Non-Contradiction’, Philosophiegeschichte und Logische Analyse, 1 (1998),
Chapter 2: ‘Truth and Contradiction’, Philosophical Quarterly, 50 (2000),
Chapter 3: ‘Perceiving Contradictions’, Australasian Journal of Philosophy, 77
(1999), 439–46; and ‘Could Everything be True?’, Australasian Journal of Philosophy, 78 (2000), 189–95.
Chapter 4: ‘What Not? A Defence of a Dialetheic Account of Negation’, in
D. Gabbay and H. Wansing, (eds.) (1999), What is Negation?, Dordrecht: Kluwer
Academic Publishers, 101–20.
Chapter 5: ‘Boolean Negation and All That’, Journal of Philosophical Logic, 19
(1990), 201–15.
Chapter 6: ‘Can Contradictions be True? II’, Proceedings of the Aristotelian Society, suppl. vol. 67 (1993), 35–54; and ‘Rational Dilemmas’, Analysis, 62 (2002),
Chapter 7: ‘Why it’s Irrational to Believe in Consistency’, in B. Brogard and
B. Smith (eds.), Rationality and Irrationality, Proceedings of the 23rd International
Wittgenstein Symposium, Vienna: öbv&hpt Verlagsgesellschaft mbh & Co. (2001),
Chapter 8: ‘Paraconsistent Belief Revision’, Theoria, 68 (2001), 214–28.

Łukasiewicz’, Studia Logica, 74 (2003), 441–68.
