La decadencia de Occidente
There is another strain of thought generally associated with a pessimistic worldview, this is the pessimism of cultural criticism and social decline which is seen in Oswald Spengler's "The Decline of the West". Spengler promoted a cyclic model of history similar to the theories of Giambattista Vico. Spengler believed modern western civilization was in the 'winter' age of decline ("untergang"). Spenglerian theory was immensely influential in interwar Europe, especially in Weimar Germany. Similarly, traditionalist Julius Evola thought that the world was in the Kali Yuga, a dark age of moral decline.
