This paper explores the legacy of the Czech philosopher and theologian Božena Komárková, specifically her perspective on antisemitism and the universal struggle for human rights. Drawing on her post-war reflections written shortly after her release from Nazi imprisonment, the text highlights her assertion that the Nuremberg laws constituted a profound insult to humanity and a critical challenge to the global conscience. The document analyzes how Komárková perceived racial hatred not merely as a localized political issue, but as a direct assault on the essence of human dignity. It bridges these historical ethical positions with contemporary political realities, pointing out the persistence of antisemitic threats in the modern world, particularly within the rhetoric of current leaders such as those in Iran. By drawing these parallels, the work emphasizes the enduring relevance of Komárková’s warnings and the necessity for constant vigilance against forms of intolerance that continue to threaten the moral foundations of global society decades after World War II. Ultimately, the text serves as a reminder of the duty to defend humanity against ideologies of hate across different eras.
