Graham,
Thanks for the mention.
I would point out one argument that goes to both the physical and the spiritual is whether reality is fundamentally monist, or dualist.
Physics keeps trying to find that smallest bit, be it atoms, quanta, or strings, yet the evident fact is it's more positive and negative charge.
Much of our social disfunction is due to the two sides of the spectrum being unwilling to accept the legitimacy of the other. Can you imagine a society, or even organic function, without both tradition and renewal. Like cycles of the seasons. Expand, consolidate.
How much of our current society, let lone science, is stuck in the shadow of monotheism?
Remember democracy and republicanism originated in pantheistic societies. The family as godhead.
The Romans adopted a monotheistic sect, as state religion, as the Empire coalesced out of the ashes of the Republic. Basically the Big Guy rules.
Yet a spiritual absolute would be the essence of sentience, from which we rise, not an ideal of wisdom and judgement, from which we fell.
The light shining through the film, than what the images on it are doing.
Ideals are not absolutes.
Image if everyone thought their ideals were absolute.
It pretty much describes the world we live in.
