It's a pantheistic God that falls out of the scientific picture of things. Scientific theories have proved to be realistic to the extent that they're counterintuitive. And that sets up a clash between the natural facts and the intuitions or trances that make up our lifeworld. That clash is our existential condition, and to appreciate nature's inhumanity/absurdity is to confront that clash.

I don't see the resulting awe or horror as being parochial. Generally, the idealistic countercultures are radical in breaking free from the stale, mainstream compromises that paper over the clash by positing personifications that trivialize the otherness of nature.

Sure, human reactions would all be merely human. But there's a difference between settling for pablum, and attempting to stretch our minds. The more we adapt our intuitions, perhaps the more transhuman we become.
