the.com/contradictory

two truths in a knife fight, both refusing to die.

means Describing two statements, ideas, or facts that clash so directly that they cannot both be true at the same time.

from From Latin contra, "against," plus dicere, "to speak" — so a contradiction is literally a speaking-against. The two halves were fused into contradicere, "to oppose in speech," which gave Latin contradictorius and reached English through Old French by the late Middle Ages, carrying that built-in argument with it.
