Foucault proposes the notion of discipline as an alternative to sovereign power, but he also talks about different forms of power, particularly the notion of governmentality, which is really to understand how governments operate, what governments do, how governments decide to regulate and organise the lives of their population.
He introduces a notion of “biopower”, the power over life. Foucault uses the idea of biopower to talk about the politics of life, the life of the population. He’s interested in things such as the census in terms of birth rates, death rates, soil fertility. How can you feed a population? How can you keep them safe from infectious diseases? How can you prevent natural disasters from devastating the population?
Foucault’s work on biopolitics has been influential and important in a range of fields, and perhaps, particularly, in the present moment of the pandemic. People are very interested in these questions of population health vaccination programmes and what you might need to do to keep a healthy society and prevent people from being subject to harm. So, there’s a lot of work that Foucault does that has been used and employed by people in very contemporary issues, whether it’s around health, politics, policing, the question of prison reform and so on.
