Necessity is an independent concept. It has a different structure from logic, morals, or meaning. Its function lies entirely in the role it plays. What doesn't play a role shouldn't exist. What necessity requires does need to exist. That's what you call dramaturgy.

individuals are concerned notwith the moral issue of realizing these standards, but withthe amoral issue of engineering a convincing impression thatthese standards are being realized. Our activity, then, islargely concerned with moral matters, but as performers wedo not have a moral concern in these moral matters. Asperformers we are merchants of morality. Our day is givenover to intimate contact with the goods we display and ourminds are filled with intimate understandings of them; but itmay well be that the more attention we give to these goods,th e more d is ta n t we feel from them and from those who arebelieving enough to buy them. To use a different imagery,the very obligation and profitablility of appearing always ina steady moral light, of being a socialized character, forcesus to be the sort of person who is practiced in the ways ofthe stage.
