BP Morton has an interesting blog post arguing that we need a philosophy of etiquette, here. I wholeheartedly agree, but would add that were the profession even a bit more broad minded, it would discover that multiple such philosophies exist in early Chinese philosophical traditions, complete with full-throated advocacy of etiquette and some of the funniest philosophical etiquette skeptics that ever blew raspberries at all (i.e., Zhuangzi). My own sense is that developing a robust contemporary philosophy of etiquette would require shifts in how philosophy understands itself and how it approaches its subject matter. For something in this vein, see here.
