the.com/contradiction
two truths in a knife fight, both refusing to die.
means A statement, idea, or situation that conflicts with another, so that both cannot be true or hold together at the same time.
from From Latin contradictio, built from contra- 'against' plus dicere 'to speak' — literally a speaking-against. The Latin verb contradicere meant to oppose or gainsay, and the word arrived in English through Old French in the medieval period, carrying that sense of words set squarely against words.
