What makes post-truth politics so difficult to resist is its apparently democratic character that claims to challenge bureaucratic depoliticisation, the rule of experts and the disappearance of alternatives to the hegemonic policy. Sergei Prozorov refutes this interpretation, arguing that the post-truth ideology leads to the degradation of the public sphere that is essential to democratic governance. Rather than enable resistance to expertise-based biopolitical governmentalities, truth denialism dissolves the only framework where their contestation and transformation could take place. In contrast, Biopolitics after Truth argues for a positive role of truth-telling in the democratisation of biopolitical governance.
