Take for example, an educational institution: the disposal of its space, the meticulous regulations which govern its internal life, the different activities which are organized there, the diverse persons who live there or meet one another, each with his [sic] own functions, his well-defined character…. The activity which ensures apprenticeship and the acquisitions of aptitudes or types of behaviour is developed there by means of a whole ensemble of regulated communications (lessons, questions and answers, orders, exhortations, coded signs of obedience, differentiation marks of the “value” of each person and of the levels of knowledge) and by the means of a whole series of power processes (enclosure, surveillance, reward and punishment, the pyramidal hierarchy).
