Post-truth and lie. Variations on Hannah Arendt

The essay reflects on the harmful effect that recourse to post-truth (modern form of political lie) supposes for democracy. Taking Hannah Arendt's thought as a reference, the Author analyzes the role that truth plays in the political sphere and the recourse to lying as a mode of domination by totalitarian political systems where reality constitutes an uncomfortable fact. Opposite with these systems, democracies try to preserve the autonomy of citizens to shape their political preferences, in a context dominated by reason and truth, against the deformations of reality generated by the use of emotions and lies.
