The emergence of post-truth politics – a political culture in which emotional appeals, subjective beliefs, and deliberate falsehoods overshadow objective facts – has fundamentally challenged the foundations of liberal democracies. The destabilization of truth is not merely a byproduct of the digital age or mass media manipulation but represents a deeper erosion of trust in institutions and authority. In this context, the deliberate use of disinformation and the fragmentation of the public sphere have heightened political polarization, making it increasingly difficult to establish common ground. These developments call for theoretical frameworks to diagnose and address this phenomenon.
Hannah Arendt’s political philosophy offers precisely such a framework. Her exploration of the fragile nature of factual truth, the role of organized lying in reshaping public perception, and the significance of authority and the public sphere sheds light on the dynamics of post-truth politics. Arendt’s reflections not only elucidate how the systematic denial of truth destabilizes public trust but also demonstrate how this denial fractures the coherence of a shared political reality, leaving societies vulnerable to manipulation and authoritarian tendencies. This thesis argues that Arendt’s distinctions between factual and rational truth, her critique of the loss of authority, and her conceptualization of the public sphere as a space for dialogue and plurality offer an indispensable lens for understanding post-truth politics. It explores how contemporary disinformation strategies parallel the mechanisms Arendt identified in totalitarian regimes, and how these strategies contribute to democratic backsliding.
It further examines how these ideas provide insight into contemporary developments, such as the deliberate delegitimization of factual truth in public discourse, exemplified by Donald Trump’s rhetoric on “fake news.” By engaging with Arendt’s work conceptually, this thesis seeks to deepen our understanding of the underlying forces driving post-truth politics and their implications for democratic stability.

Excerpt from the Book
3.2. Donald Trump’s Rhetoric and the Destabilization of Truth
Post-truth politics becomes most visible when their abstract mechanisms materialize in concrete political events. Few moments illustrate this more vividly than Donald Trump’s address at the Ellipse on January 6th, 2021 – now remembered as the “day of the Capitol attack.” Standing before a large crowd, Trump presented a narrative of systemic election fraud, delegitimized American democratic institutions, and urged his supporters to “fight like hell” to overturn the election results. His rhetoric did not merely reflect the breakdown of political discourse; it exposed the extent to which disinformation can be weaponized for political mobilization.
From the very beginning of his presidency, the assault on factual truth was unmistakable. Trump’s press secretary Sean Spicer famously claimed that the inauguration crowd was “the largest audience to ever witness an inauguration, period,” a statement immediately disproven by photographic evidence. This episode signaled the start of a presidency defined by continuous and escalating assaults on objective reality. The January 6th speech was not a rupture, but the culmination of years in which reality was steadily bent to serve political identity. Trump’s presidency shows all too clearly how the progressive erosion of reality undermines public trust and how this corrosion, already apparent, is likely to worsen in the years to come, further fraying the fragile fabric of factual truth in a country more polarized than ever.
From the opening lines of his speech, Trump sought to cast doubt on the media and claimed that the truth was being actively suppressed: “We have hundreds of thousands of people here,” he says, “and I just want them to be recognized by the fake news media.” This claim serves multiple purposes: it flatters the audience, affirms their belief in being silenced, and draws a sharp dividing line between “the people” who know the “real truth” and the institutions portrayed as corrupt – journalists, judges, and elected officials alike.
