This essay is aimed at thematising the topic of post-truth in the ‘post-democratic’ constellation. From this perspective, it firstly illustrates contents and features of the broad concept of post-democracy, therefore analysing both the issue of the crisis of democracy and the impact of contemporary neoliberal platform capitalism on these process. Hence, it addresses the related topics of new technologies and changes in political communication, along with the unfolding of the neo-populist phenomenology. A number of concluding meta-theoretical reflections on the relationship between democracy, knowledge and political representation are also developed.
