Full Idea
Foucault's analysis suggests that meaningful revolution, hence genuine liberation, is impossible: the only alternative to the modern net of micro-centres of power is totalitatian domination. Hence his politics, even when revolutionary, is always local.
Gist of Idea
Power is localised, so we either have totalitarian centralisation, or local politics
