It does seem the core sticking point is monotheism. Whether Jewish, Christian, or Muslim.

Ideals are not absolutes. Truth, beauty, platonic forms are ideals. The codes, creeds, heroes, narratives at the gravitational center of every culture are ideals. Without which they would break apart and be scattered to the winds. Tower of Babel.

Yet none are absolute. The universal is the elemental, so 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 and animating the film, rather than the stories playing out on it.

Morality is obviously not absolute, given it couldn't be transgressed, if it were. Like a temperature below absolute zero.

Morals are the ideals, the codes, behaviors, systems that enable a healthy and functional society. One of which, organically, is one's value and status a function of what one adds, not what one can extract. Yet we have grown from groups small enough to understand this, "It takes a village..", to nations of millions of people in those last few thousand years, so developing that sense will take a few more serious ups and downs. Of which we are on the edge of engaging.

Reality is bottom up, but our minds are model making processes, so we all apply the maps most beneficial to us, even though they often conflict with other's maps and models.

So there is this feedback, diplomacy, politicking, between all the nodes in the network.

Though if lots of people somehow insist their map, their beliefs, their religion, is somehow absolute and universal, there can be no getting along. It's all against all and the world burns down.
