They exercise a subtle force upon the members of a Culture, and they fight with other Cultures. Though the terminology is not quite the same, Yockey's Cultures seem to be metaphysical entities of the same order as the Aeons of more recent right-wing occultists. Yockey is also taken by other crank ideas which I have not seen elsewhere, but which I suspect are probably not original with him. For instance, in explaining the deleterious effects of the bout of immigration to the US from about 1900 to 1920, he states the remarkable principle that immigration has never actually increased the total population. Rather, there is some ideal figure toward which the population is tending.
Immigration simply causes the birthrate of earlier arrivals to fall.
Thus, he says, the immigration of the first two decades of the 20th century simply replaced Western people with Slavs and Jews and Asians. Something that Yockey has in common with Nazism as it is generally understood is the designation of trends he dislikes as pathologies, which in Yockey's system become pathologies of Culture. Although the idea is stated in neutral terms, it soon becomes evident that the chief cultural distorter of the last two centuries is the Jews, and that almost the whole of 20th-century art and politics has been one, long Jewish distortion. Yockey identifies two great 20th-century revolutions. One was the American Revolution of 1933, whereby the cultural distorter took full control of the United States, and the other the European Revolution of 1933, when Europe first began to organize itself against the Slavic threat from the East.
