In this volume, though, Foucault begins to turn his attention to the history of "governmentality," from the first centuries of the Christian era to the emergence of the modern nation state--shifting the center of gravity of the lectures from the question of biopower to that of government. In light of Foucault's later work, these lectures illustrate a radical turning point at which the transition to the problematic of the "government of self and others" would begin.
