The logical fallacy of monotheism is that 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 fact we are aware, than the details of which we are aware.
More the new born, than the wise old man. The light shining through the film, than the images on it.
Conflating the ideal, which is aspirational, with the absolute, which is elemental, does create the assumption one's ideals should be universal and absolute. Which is a failure of philosophy, rather than religion, which is social and cultural in nature.
Societies do need to transmit some degree of structure to a constantly regenerating population and there is a strong tendency to keep referring back to one's elders and their elders, so we do naturally build on some fairly primal foundations.
The only true absolute is the equilibrium. The zero between positive and negative. The flatline between the ups and downs. The relativistic frame with the longest ruler and the fastest clock. The absolute zero of the unmoving void.
Yet the absolute stands in contrast with the infinite. The umeasureable everything.
So we exist in this tension between everything fading out and everything cancelling out. Nodes coalescing inward, as networks expand outward. Organisms synchronizing their clocks, to ecosystems harmonizing their clocks.
Yin and yang, rather than God Almighty.
It is just that even western secularism exists in this long shadow of the absolute, where ideals become ideologies, tools become gods and mediums become the message.
We are linear, goal oriented creatures in a cyclical, reciprocal, feedback generated reality.
We assume if a little is good, more is always better. Time as the present moving past to future, rather than change turning future to past. We still see the sun rising in the east and setting in the west.
Wisdom is a process, not a goal.
We are still children.
