That’s certainly an interesting and detailed prehistory you’ve written, but I don’t see how it undermines or is even particularly relevant to this article on how science and philosophy have arguably refuted and humiliated traditional religions, making the notion of hypermodern spirituality dubious.
By the way, I wrote “Hypermodern Religion from the Ashes” a couple weeks ago. As it happens, the article I said was going to write, which would address the transitions from prehistory to history, from animism to hierarchical religion and so forth, I’m writing now.
But I don’t see how your account of the origins of inequality and of bad religions from an initial nondual experience is inconsistent with my point about how philosophical naturalism challenges all uplifting religious outlooks, a challenge which seems best met by existentialism tempered with cosmicism. You seem to want to meet this challenge by leapfrogging theism straight back into premodern mystical monism. We might as well try rushing headlong back into our childhood naivety, which would be psychologically impossible and disingenuous.
