Reclaiming Liberal Democracy in the Postfactual Age is a systematic exploration of the many ways in which post-truth politics constitutes a fundamental challenge and, indeed, an existential threat to liberal democracy as we know it.The book addresses this existential threat by exploring the dynamic interplay of the various phenomena that constitute the post-truth condition, while also exploring possible responses aimed at reclaiming liberal democracy. The book's guiding assumption is that post-truth politics must be conceptualized as the ideal-typical endpoint of ongoing developments of liberal-democratic political culture. These developments are intimately connected to the ongoing transformation of the information environment, brought about by social/digital media and the recent rise of artificial intelligence. But they are also connected to the resurgence of populism and decreasing trust in once-trusted sources of information, in particular mainstream quality journalism, exacerbated by targeted disinformation campaigns at the hands of foreign powers.
