Erving Goffman said this quote

Here I want to stress that perception of losing one’s mind is based on culturally derived and socially ingrained stereotypes as to the significance of symptoms such as hearing voices, losing temporal and spatial orientation, and sensing that one is being followed, and that many of the most spectacular and convincing of these symptoms in some instances psychiatrically signify merely a temporary emotional upset in a stressful situation, however terrifying to the person at the time. Similarly, the anxiety consequent upon this perception of oneself, and the strategies devised to reduce this anxiety, are not a product of abnormal psychology, but would be exhibited by any person socialized into our culture who came to conceive of himself as someone losing his mind.

~ Erving Goffman

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.
