Foucault’s 1976 lecture ‘The Mesh of Power’ is available online in English (with a link to the French) at Viewpoint Magazine. This lecture was previously translated by Gerald Moore for the Space, Knowledge and Power: Foucault and Geography collection Jeremy Crampton and I edited. But this version includes the discussion that followed Foucault’s lecture. Thanks to Peter Gratton for the link.
