Dialetheism is the view that there are true contradictions, i.e. true claims of the form ‘P and not-P’ (or ‘P and it is not the case that P’). For example, I mentioned ‘this sentence is not true’ earlier. According to standard versions of dialetheism, this sentence is in fact both true and not. So the claim to this effect would be an example of a true contradiction. Why adopt such a crazy view? The apparently most promising argument, which had been stressed by Graham Priest, was essentially this: one should adopt this view because any more orthodox solution of paradoxes such as the Liar will involve severe expressive restrictions.
