"We cannot possibly get beyond our present level of culture unless we receive a powerful impetus from our primitive roots."But we shall receive it only if we go back beyond our cultural level,thus giving the suppressed primitive man in ourselves a chance to develop.
"We need some new foundations,we must dig down to the primitive in us,for only in the conflict between civilised
man and the Germanic barbarian will there come what we need:a new experience of the gods". [Jung]

Race as a political religion is particularly potent [and if we look at the spiritual/ideological vacuum at the centre of today's Global Capitalism,we may feel that such a Mythos is actually NECESSARY for the survival of Western civilisation].
Houston Stewart Chamberlain was a 19th century writer [an Englishman who married into the Wagner clan] who recognised the danger of what he called 'Folk Chaos' ;
"The monstrosity of the state without a nation;that empty form,that soulless congery of humanity;that union of mongrels bound together only by a community of taxes and superstitions,not by a common origin and a common heart-beat;that crime against the race of mankind which we have summed up in the word 'Folkchaos'. Even today we have not yet succeeded in purging our blood of all the poisons of that chaos". [Chamberlain,'Foundations of the 19th Century']

It was the ability of the race mythos to inspire the Will of Aryan man that made it so precious;
"Race lifts a man above himself: it endows him with extraordinary--I might almost say Supernatural--powers,so entirely does it distinguish him from the individual who springs from a chaotic jumble of peoples". [ib.]

Now Nietzsche eschewed 'ideals'.He saw the master race as an actuality:it was a 'fact of recurrence';
"The most important thing is that the possibility has been established for the production of international racial unions whose task will be to rear a Master Race,the future 'Masters of the Earth',--a new,tremendous Aristocracy,based on the severest self-legislation,in which the Will of Philosophical Men of Power,and Artist Tyrants will be made to endure for Thousands of Years--a Higher kind of Man who,thanks to their Superiority in Will and knowledge,riches and influence,employ democratic Europe as their most pliant and supple instruments". [Nietzsche,WM 960]

To Nietzsche this was the one,"SERIOUS topic;the 'European problem',as I understand it,the rearing of a New Ruling Caste for Europe". [Nietzsche,BGE 251]
