Abstract
Post-truth is a new phenomenon that has emerged in recent years. It can also be said that this is a new moment in the relationship between truth and falsehood. In retrospect, we can say that history is immersed in a constant struggle between truth and falsehood. And the post-truth phenomenon is what it is today. The post-truth phenomenon is closely related to modern new technologies and politics. The post-truth phenomenon, based on media and social media, is considered the most effective tool of populism. The main goal of this study is to examine post-truth in the context of the political thought of Hannah Arendt, a prominent figure in political philosophy. This is because the article's main argument is that the root of post-truth lies in the relationship between truth and falsehood. As Hannah Arendt explores the relationship between truth and falsehood in her work from the perspective of political philosophy, this article attempts to analyze today's post-truth phenomenon from the perspective of her political thought. This article makes the following hypothesis: Hannah Arendt addressed the issue of post-truth in politics before the term “post-truth” appeared. The study used analytical methods to analyze political and philosophical texts by Hannah Arendt
