Abstract
The purpose of this paper is to present some thoughts upon the ever pressing question of the role of justice in our societies, according to Michel Foucault. Centered upon Discipline & Punish: The Birth of the Prison, the paper draws the guidelines which Foucault developed about the aggiornamento of the exercise of power and its changing methods, from torture to the scientific methods which he named technologies of the self. Going from the exercise of violence centered upon the body to its submission by means of idea and mind control, power has associated itself to the scientific approach of identity, leading to a controllable abnormality. All of this in the name of a population policy, a bio power which ensures the docility of individuals while optimizing their productive force. Hence the remaining epigraph quoted challenge where Plato provocatively States: justice is the same everywhere, it is the rule of the strongest.
