This is only half related. I feel like I can only think about this in half related analogies. But I have been thinking about the world the last few years through a cluster of related metaphors which I've seen in books and things. Eg the garden & wall thing where the fruit / calories are energy/structure being protected by a barrier. Membrane and vital center. Hearth and mortar, keep and walls, nucleus and membranes. Life keeps itself apart from the flows and fluxes, keeps itself apart from other life, in order to persevere. But the garden requires a stream to stay alive, the organism must feed, which requires exposure to the outside. It stabilizes itself through change. Heraclitus, the Ship of Theseus. Which sort of gets at how apartness and togetherness are intertwined concepts maybe?
All these atmospheres and envelopes right we all understand this. There is a garden and it's surrounded by wilderness and the wilderness is often hostile/indifferent. And a monomyth is also the war, Iliar and Odyssey—the hero journey is that venture, often undertaken for a vital grail, or for a woman/women, into the wilderness, essentially to rob some other membrane of its vital centers.
It's a simple and commonsense thing, not radical, just that we are sorta little walking factory fortresses, batteries with skins to protect our precious batteries. But I just bring it up to say that it there are almost these two sides. Are you team oneness or are you team flow. But its doesnt divide up so easily
