When a theological world view dominated, deviance was sin; when the nation-states emerged from the decay of feudalism, most deviance became designated as crime; and in our own scientifically oriented world, various forms of deviance are designated increasingly as medical problems. Thus we view the medical paradigm as the ascending paradigm for deviance designations in our postindustrial society.
[T]here are no illnesses in nature, only relationships. There are, of course, naturally occurring events, including infectious viruses, malignant growths, ruptures of tissues, and unusual chromosome constellations, but these are not ipso facto illnesses. Without the social meaning that humans attach to them they do not constitute illness or disease: The fracture of a septuagenarian's femur has, within the world of nature, so more significance than the snapping of an autumn leaf from its twig; and the invasion of a human organism by cholera germs carries with it no more the stamp of "illness" than the souring of milk by other forms of bacteria. (Sedgwick, 1972, p. 211)
A slow but steady transformation of deviance has taken place in American society. It has not been a change in behavior as such, but in how behavior is defined. Deviant behaviors that were once defined as immoral, sinful, or criminal have been given medical meanings. Some say that rehabilitation has replaced punishment, but in many cases medical treatments have become a new form of punishment and social control.
