“The study of abnormality is one of the main ways that power relations are established in society. When an abnormality and its corresponding norm are defined, somehow it is always the normal person who has the power over the abnormal.
The psychologist tells us about the madmen, the physician about the patients, the criminologist (or the legal theorist, or the politician) talks about the criminal, but we never expect to hear the latter talk about the former - what they have to say has already been ruled irrelevant, because by definition they have no knowledge (but that is code for not wanting them to have any power).”
