DUEL, n. A formal ceremony preliminary to the reconciliation of two enemies. Great skill is necessary to its satisfactory observance; if awkwardly performed the most unexpected and deplorable consequences sometimes ensue. A long time ago a man lost his life in a duel.
Ambrose Bierce
Poetry is a rich, full-bodied whistle, cracked ice crunching in pails, the night that numbs the leaf, the duel of two nightingales, the sweet pea that has run wild, Creation's tears in shoulder blades.
Boris Pasternak
I thoroughly disapprove of duels. If a man should challenge me, I would take him kindly and forgivingly by the hand and lead him to a quiet place and kill him.
Mark Twain
