In our society, defecation involves an individual in activity which is defined as inconsistent with the cleanliness and purity standards expressed in… - Erving Goffman

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.

The central feature of the stigmatized individual's situation in life can now be stated. It is a question of what is often, if vaguely, called 'acceptance'. Those who have dealings with him fail to accord him the respect and regard which the un-contaminated aspects of his social identity have led them to anticipate extending, and have led him to anticipate receiving; he echoes this denial by finding that some of his own attributes warrant it.

The Greeks, who were apparently strong on visual aids, originated the term stigma to refer to bodily signs designed to expose something unusual and bad about the moral status of the signifier. The signs were cut or burnt into the body and advertised that the bearer was a slave, a criminal, or a traitor — a blemished person, ritually polluted, to be avoided, especially in public places. Later, in Christian times, two layers of metaphor were added to the term : the first referred to bodily signs of holy grace that took the form of eruptive blossoms on the skin; the second, a medical allusion to this religious allusion, referred to bodily signs of physical disorder. Today the term is widely used in something like the original literal sense, but is applied more to the disgrace itself than to the bodily evidence of it. Furthermore, shifts have occurred in the kinds of disgrace that arouse concern. Students, however, have made little effort to describe the structural preconditions of stigma, or even to provide a definition of the concept itself. It seems necessary, therefore, to try at the beginning to sketch in some very general assumptions and definitions.
