  While LNC has traditionally remained more sacrosanct, reflecting its position as the primus inter pares of the indemonstrables, transgressing this final taboo has become increasingly alluring in recent years. The move here involves embracing not gaps but truth value gluts, cases in which a given sentence and its negation are taken to be both true, or alternatively cases in which a sentence may be assigned more than one (classical) truth value, i.e.  both True and False. Parsons (1990) observes that the two non-classical theories are provably logically equivalent, as gluts arise within one class of theories precisely where gaps do in the other; others, however, have argued that gaps (as in Intuitionist non-bivalent logics) are easier to swallow than gluts (see papers in the Priest et al. 2004 collection for further debate). Dialetheists reject the charge of incoherence by noting that to accept some contradictions is not to accept them all; in particular, they seek to defuse the threat of logical armageddon or “explosion” posed by Ex Contradictione Quodlibet, the inference in (8):
