The article is dedicated to the role of emotions in the political theory of Hannah Arendt. Her thoughts on emotions turn out to be a stumbling block for most contemporary defenders of emotions in politics, and many of Arendt’s opponents and critics focused on her ideas on emotions in order to refute or reinterpret them. However, being separated from the crucial concepts of Arendt’s theory, emotions cause confusion. Therefore, the approach displayed in the article implies a discovery of their influ-ence on public space and plurality, as well as on other significant concepts in Arendt’s theory. Plurality, as a precondition of public space, is manifested by means of the uniqueness of speech and actions, and any appeal to common emotions as the foundation of a better public realm leads to the absence of plurality and uniqueness. Thus, the suggested treatment allows demonstrating a correlation between emotions and politics and, moreover, distinguishing the alternatives of emotions in poli-tics, such as solidarity instead of compassion, or courage instead of fear. In addition, the ideas of understanding and reconcilia-tion with the world are examined in order to demonstrate their significance for the existence of plurality and public space, un-like those emotions that destroy both of them.
