You are left to blame it on other humans, usually working in huge, well organized, highly invisible secular conspiracies --- which is why there are no signs of their intervention.
But if you claim you are very religious, as most "optimistic paranoids" do, why not credit this to God or the Devil and their minions : isn't doing invisible things in mysterious ways supposed to be in their very un-Earthly nature?
And don't most religions also teach us that Man is fallible and imperfect - not at all the sort of being capable of pulling off huge conspiracies -- or in keeping his mouth shut if he did ?
Those who are extreme optimists about controlling Nature, (aka DENIERS of any limits on Man's abilities), in practise also act as if they disbelieve God or the Devil can interfere in human activities.
As a result they are left in the position of those Victorians who lost their traditional explanation crediting God or Nature for their strong sense of the Sublime and had to find new explanations to account for it : most opting for the new Technological Sublime, in many scholars' view.
DENIERS all believe in the Technological Sublime in spades, in the technical fix for what ever small, temporary, local, problems Nature or Man can throw our way.
Extreme optimism about Man controlling Nature leads to extreme paranoia about Man controlled by other men - acting in secret conspiracies....
But that isn't enough : for mixed in with the "awe" of the traditional sense of the Sublime, is also a healthy dollop of "fear".
Free floating fear - nationalistic,ethnic, whatever - really grew up along with the new age of Scientism , being in fact a product of it.
For if we no longer find it easy to fear the dark, the tiger or the Devil, we now must fear being overrun by the Yellow Peril or the Socialist Hordes or the Jewish Banksters instead......
