The political governmentality in Foucault's thought

This article intends to show that the publication of Michel Foucault's courses, Securite, territoire, population and Naissance de la biopolitique, given at College de France, shows not only a change of his analytics of power, but also the problematization of a new background for the continuation of his thinking. This background is the concept of governmentality. This neologism allows Foucault to analyze domains such as Arts of government, Liberalism and Neo-liberalism.
