Historian Fritz Stern examines the intellectual roots of German extremism through the lives and thought of three figures: Paul de Lagarde, Julius Langbehn, and Moeller van den Bruck. These cultural critics, writing between the 1870s and 1920s, developed a politics of cultural despair that rejected liberal modernity in favor of mythic German authenticity. Stern traces how their attack on materialism, rationalism, and cosmopolitanism created an ideological framework that the Nazi movement would later exploit, even though none of the three were themselves Nazis. The book examines how each critic diagnosed German cultural decline and proposed redemption through a return to authentic Germanic values, invariably defined against Jews, liberals, and modernity itself. Stern, who fled Germany as a child, writes with intimate knowledge of the tradition he analyzes and its consequences. His work was pioneering in treating ideas as having historical consequences, showing how cultural criticism can create space for political extremism even when critics themselves stop short of political commitment. For anyone seeking to understand how democracies become vulnerable to authoritarianism, this study of pre-Nazi German thought remains essential, showing how despair about cultural decline can metastasize into something far more dangerous.
