Given that trivialism is absurd, which has been granted in this entry (though why this is so is not as easy a question as it might appear: see Priest, 2000, and Priest, 2006, Ch. 3), dialetheism must be rejected.

From Philosophical Pontifications: 'Dialetheism, for those not in the know, is the thesis that that some contradictions are true. It is platitudinous that some of the things people say are true and others false—and some, dialetheists add, are both true and false.'

Oh, and on the origins: 'Though dialetheism is not a new view, the word itself is. It was coined by Graham Priest and Richard Routley (later Sylvan) in 1981... The inspiration for the name was a passage in Wittgenstein's Remarks on the Foundations of Mathematics, where he describes the liar sentence (‘this sentence is not true’) as a Janus-headed figure facing both truth and falsity... Hence a di-aletheia is a two(-way) truth. Unfortunately, Priest and Routley forgot to agree how to spell the ‘ism’, and versions with and without the ‘e’ appear in print.'
