The phenomenal success of the rap musical Hamilton has acquainted many theater goers with the custom of dueling. Three duels take place in the story. To ensure the accuracy of their depiction, Lin-Manuel Miranda consulted Joanne Freeman, whose book Affairs of Honor he deemed “indispensable.” Dueling did not lead to a happy ending for the show’s namesake, or for his son Philip. But that doesn’t mean that there is nothing to be said for the custom. A respectable – and not entirely facetious – argument can be made for its revival.
