I suspect the difference between pantheism and panentheism is a technicality. The supernatural residue in panentheism would be an epistemological matter, speaking to our ignorance. Or else panentheism would be a political compromise between pantheism and theism.
I've written a number of articles on consciousness, and I have another coming out in a week or two (featuring pygmy marmosets).
Saying there's something great only behind consciousness strikes me as anthropocentric. I use pantheism to reflect how there's something strange implicit in absolutely everything. Nature's very godless physicality should be re-enchanted.
