In the Spring of 1939, at the the New York World's Fair, Modernity or Scientism (the words are totally inter-changable) promised the deserving parts of the world a future of Four Freedoms: eventual freedom from material limitations, from catastrophes like the weather, from dependence upon lesser breeds and beings and, above all , from uncertainty.
In Fall of 1945, another set of Four Freedoms - originating from a speech given by FDR in January 1941 - seemed to offer all the world's human beings a more credible and attractive life --- if equally set at some distant date in the future.
But also in the Fall of 1945, a few people, on the way to becoming post-modernist, were beginning to ask whether even those Four Freedoms were an adequate or accurate rebuttal to Modernism's Four Freedoms.
Today, to be fully post-Modernist and to be fully post-Scientism , to be fully in the Twenty First Century , is to totally accept the permanent existence of material limitations, catastrophes, uncertainty and the right of existence for lesser breeds and lesser beings.
So there we have it : the rise and the fall of Scientism, from apogee to nadir ....
