My gut instinct is that physicists are terrified of the Zero Point Field/Quantum Vacuum, because some form of determinism is as close to a God as most of them want to get. They want to BE gods, not learn about one. And incorporating indeterminacy/randomness into the core of physical theories as an inescapable fact cuts them down from demiurges to technicians.
Arrogance. If you want the answer to why people do stupid fucking things, the two answers are actual stupidity, which is much rarer than one might suppose, and arrogance in some form, some refusal to accommodate oneself to what is.
It might be appropriate here, too, to follow up on my post about assuming moral imperfection as necessary. Here is the thing: if you keep in your own mind your own failings, brought about because you do not believe in perfection, brought about because you believe notions of perfection must inherently be based on the limitation of accurate perception (which is to say the willful suppression of wisdom), then you cannot judge others with a clear conscience either.
And this is not to say you should not judge, but it is to say that this, too, is quite often a sin. Everything good begins with accurate perception. It does not flow from ideas. Not even this idea, because sometimes you need principles.
What is the essence of a dance? Flow. Movement. This is why I made Perceptual Movement a core principle, with curiosity the simplest way of expressing this idea.
