Oswald Spengler (1880–1936) was a philosopher of history who is regarded as one of the principal Conservative Revolutionary figures of the Weimar period in Germany. His most important work was his two volume 1918/23 book The Decline of the West, in which he theorised that all civilisations go through an inevitable cycle of ages of rise and decline in power, with the West currently entering its declining period. The book went on to be immensely influential throughout the world. He saw a distinction between what he termed “German socialism” and Marxism. Although a nationalist, he was skeptical about the Nazis when they came to power, disagreeing particularly with their racial policies. He joined the German Academy in 1933. Arktos has issued reprints of the German and Swedish-language editions of his books, Man and Technics, Prussianism and Socialism and The Hour of Decision. English translations are forthcoming.
