Through an analysis of the changing thought and career of the Austrian poet, librettist, and essaist Hugo von Hofmannsthal (1874-1929), Broch attempts to define and analyze the major intellectual issues of the European fin de siècle, a period that he characterizes according to the Nietzschean concepts of the breakdown of rationality and the loss of a central value system. The result is a major examination of European thought as well as a comparative study of political systems and artistic styles.
