 Foucault’s genealogy follows Nietzsche as well as existential phenomenology in that it aims to bring the body into the focus of history. Rather than histories of mentalities or ideas, genealogies are “histories of the body.” They examine the historical practices through which the body becomes an object of techniques and deployments of power. In Discipline and Punish, Foucault shows how disciplinary techniques produce “docile bodies”: bodies of prisoners, soldiers, workers and schoolchildren were subjected to disciplinary power in order to make them more useful and at the same time easier to control. The human body became a machine the functioning of which could be optimized, calculated, and improved. Its functions, movements and capabilities were broken down into narrow segments, analyzed in detail and recomposed in a maximally effective way.
