"A City Without Jews: A Novel of Tomorrow" by Hugo Bettauer is a book that was written back in 1922, but its relevance has not been lost to this day. In this futuristic novel, the author imagines a city from which Jews suddenly disappear. This book became a kind of warning about the rise of anti-Semitism in Europe. It not only reveals social problems and injustices, but also prompts the reader to think about important questions of modernity and morality. Reading "A City Without Jews", we draw parallels between the past and the present, reflect on the consequences of intolerance and ideologies that lead to the destruction of society. Bettauer's book is not only a literary masterpiece, but also a challenge to consider the other, the different, the one who is not like us.
