Discipline and Punish
According to Foucault, it is the "effect" of power and "disciplines" (see "Discipline and Punish": construction of the subject (subjectivation or subjectification, ) as student, soldier, "criminal", etc.). Foucault believed it was possible to transform oneself; he used the word ethopoiein from the word "ethos" to describe the process. Subjectification was a central concept in Gilles Deleuze and Félix Guattari's work as well.
