@RoyTsaoNYC The story I tell is that it gets rolling as social contexts where men interact as equals rather than in a set hierarchy become more important. Anna Bryson's Courtesy to Civility is good on this. Basically, when people move from manor to city, duelling blows up.
@RoyTsaoNYC And yes, the duel of honour doesn't make much sense by today's ethical standards but that's what makes it interesting. But if you look at the literature on retribution, apology, restorative justice etc, a lot of the same issues are in play.
@RoyTsaoNYC I think it's interesting because it doesn't have to find a truth of the dispute. It the disputants acknowledge each other by duelling, the beef is squashed. It's also interestingly different from feuds which open tit-for-tat disputes that have no inherent end point.
