When a rule is enforced, the person who is supposed to have broken it may be seen as a special kind of person, one who cannot be trusted to live by t… - Howard S. Becker

Treating a person as though he were generally rather than specifically deviant produces a self-fulfilling prophecy. It sets in motion several mechanisms which conspire to shape the person in the image people have of him. It the first place, one tends to be cut off, after being identified as deviant, from participation in more conventional groups, even though the specific consequences of the particular deviant activity might never of themselves have caused the isolation had there not also been the public knowledge and reaction to it. For example, being a homosexual may not affect one’s ability to do office work, but to be known as a homosexual in an office may make it impossible to continue working there. Similarly, though the effects of opiate drugs may not impair one’s working ability, to be known as an addict will probably lead to losing one’s job... The homosexual who is deprived of a “respectable” job by the discovery of his deviance may drift into unconventional, marginal occupations where it does not make so much difference. The drug addict finds himself forced into other illegitimate kinds of activity, such as robbery and theft, by the refusal of respectable employers to have him around.

Maybe the years I spent playing the piano in taverns in Chicago and elsewhere led me to believe that the people who did that mundane work were as important to an understanding of art as the better-known players who produced the recognized classics of jazz. Growing up … may have led me to think that the craftsman who help make art works areas important as the people who conceive them... Learning the "Chicago tradition" of sociology from Everett C. Hughes and Herbert Blumer surely led to a skepticism about conventional definitions of the objects of sociological study.

All artistic work, like all human activity, involves the joint activity of a number, often a large number of people. Through their cooperation, the art work we eventually see or hear comes to be and continues to be. The work always shows signs of that cooperation.
