The total institutions of our society can be linked in five rough groupings. First, there are institutions established to care for persons felt to be both incapable and harmless; these are the homes for the blind, the aged, the orphaned, and the indigent. Second, there are places established to care for persons felt to be incapable of looking after themselves and a threat to the community, albeit an unintended one: TB sanitaria, mental hospitals, and leprosaria. A third type of total institution is organised to protect the community against what are felt to be intentional dangers to it, with the welfare of the persons thus sequestered not the immediate issue: jails, penitentiaries, P.O.W. camps, and concentration camps. Fourth, there are institutions purportedly established the better to pursue some work-like tasks and justifying themselves only on these instrumental grounds: army barracks, ships, boarding schools, work camps, colonial compounds, and large mansions from the point of view of those who live in the servants' quarters. Finally, there are those establishments designed as retreats from the world even while often serving also as training stations for the religious; examples are abbeys, monasteries, convents, and other cloisters.

In all these various instances of stigma [...] the same sociological features are found: an individual who might have been received easily in ordinary social intercourse possesses a trait that can obstrude itself upon attention and turn those of us whom he meets away from him, breaking the claim that his other attributes have on us. He possesses a stigma, an undesired differentness from what we had anticipated. We and those who do not depart negatively from the particular expectations at issue I shall call the normals. The attitude we normals have toward a person with a stigma, and the actions we take in regard to him, are well known, since these responses are what the benevolent social action is designed to soften and ameliorate. By definition, of course, we believe the person with a stigma is not quite human. On this assumption we exercise varieties of discrimination, through which we effectively, if often unthinkingly, reduce his life chances. We construct a stigma theory, an ideology to explain his inferiority and account for the danger he represents, sometimes rationalizing an animosity based on other differences, such as those of social class.

There seems to be no agent more effective than another person in bringing a world for oneself alive, or, by a glance, a gesture, or a remark, shriveling up the reality in which one is lodged.
