The book is a publication of lectures by Michel Foucault delivered at the Collge de France in the 1977-1978 academic year. The central concept of lecture courses is the concept of biopower, introduced by Foucault in 1976. The course aims to trace the genesis of this “power over life”, in the emergence of which the author sees one of the main events in the history of mankind, since this concept itself and the practices corresponding to it have made the most radical changes in the way of human existence. The ultimate goal of these changes is the emergence of Homo oeconomicus, a “civil society” and its corresponding liberal model of governance. Liberal government paradoxically combines the principle of self-limitation of power and constant government intervention to produce, increase and guarantee the freedoms that the liberal system needs.
