Abstract
Arguing against conventional ideas of power with negative and fixed nature like juristic ideas of power, Foucault asserted affirmative, positive and interchangable ideas of power. Taking leave of the conventional point of view which seeks the truth in places where there is no power, Foucault sees power-network in everyday micro relationships on the basis of his idea of "knowledge-power" spiral. He develops unique arguments on the disciplinary power and pastoral power as indivisualizing ones, and then "bio-power" as totalizing one.
