The change in the West that gained steam especially in the 20th century in the realm of worldview is that Christian orthodoxy was replaced by an ideology of collectivism as the basis of a consensus intellectual frame of reference and system of values. World War I destroyed the old Christian world and the Christian worldview that had held that old world together. This new worldview of collectivism has become a ‘secular religion’ and with the propulsion of psychology to the fore as the Priests of the new secular religion we now have what might be called, in the terminology of the shrinks, and from the view of the older Christian worldview, a psychic epidemic that now afflicts our young people who end up going on to be University trained. This collectivism is dedicated to a leveling of all distinctions among men and in culture, which again is counter-intuitive to those who still hold to the older Christian Worldview where a God ordained soft hierarchy was characteristic among men and in culture. This arc of egalitarianism, typical of the collectivist worldview began with the Enlightenment but again, it especially gained steam in the 20th century.
There is another change though that is significant. There was a also a change in the West that began in the second decade of the 20th century in terms of money and that change found the constellations of finance-capitalism, which had been separate and nationally oriented being absorbed into a greater international constellation of finance – capitalism, shotgunned by the Rothschilds and dedicated to a different set of long term interests than the Nation – State interests prior to 1913.
These changes in money and worldview have drawn the peoples of the West into a Marxism dialectic where money is thesis, socialism is antithesis and the synthesis / new thesis is the Imperium of the New World Order.
Or if you prefer, the dialectic being put differently,
Money now incessantly concentrates power, socialism promises the total dispersal and distribution of that power, and the New World order offers the resolution of the contradiction by supplying the New Imperium with a ruling dynamic that will take the concentrated power that has been seized and by the great wisdom of the Elites, men will be ruled according to what is their best interest — even if they don’t realize what is in their best interest.
