Der Untergang des Abendlandes
A 1928 "Time" review of the second volume of "Decline" described the immense influence and controversy Spengler's ideas enjoyed during the 1920s: "When the first volume of "The Decline of the West" appeared in Germany a few years ago, thousands of copies were sold. Cultivated European discourse quickly became Spengler-saturated. Spenglerism spurted from the pens of countless disciples. It was imperative to read Spengler, to sympathize or revolt. It still remains so".
