Foucault described biopolitics as "a new technology of power...exists at a different level, on a different scale, and [that has a different bearing area, and makes use of very different instruments." More than a disciplinary mechanism, Foucault's biopolitics acts as a control apparatus exerted over a population as a whole or, as Foucault stated, "a global mass." In the years that followed, Foucault continued to develop his notions of the biopolitical in his "The Birth of Biopolitics" and "The Courage of Truth" lectures.
