The history of politic is the history of the efforts of individuals or groups of individuals to accumulate, exercise, and distribute power. Indeed politics might be viewed as bounded conflict, as a means of manage conflict such that it does not deteriorate into private feuding or mob violence. We all used the word power often. We all have an intuitive understanding of the term, which is (usually) perfectly sufficient for pub conversation. But the rapidly growing mountain of literature on the concept of power indicates that this understanding is not considered adequate for academic discourse.Michel Foucault has been theorizing about and practicing a new form of politically engaged reflection on the emergence and nature of power. This reflection which Foucault calls Genealogy of power has produced some extremely valuable result.
