The sociologist and the social position
Not everyone can be a social scientist. As not everyone can be a soccer player. The only people being really able to do social science or sociology are the socially uprooted as many cases demonstrate all along the history of the social sciences; that is, those who are not well integrated in its membership groups, and which do not have reference groups: these are characterized by having a habitus which, by socialization (some would call it "by nature"), is cognitively heterodox; i.e., socially critical.
