 Dialetheism asks us to consider the possibility that a theory lacking the virtue of consistency may still overcomes its rivals in all or most of the other respects. According to dialetheists, this is actually the case with the dialetheic account of the semantics of ordinary language, whose advantages with respect to consistent accounts have already been shortly suggested above. And conversely, of course, an inconsistent theory may well be trumped by a consistent theory, all things considered. So it may be rational to reject an inconsistent position, even if it is logically possible that it is true. Rationality considerations are dealt with at length in Priest 2006.
