Do find pluralism in this sense applicable across physicality in general or purely from a categorical and linguistic stand point?
I don't really know how to answer this question tbh. I'll just write thoughts on it.
I like this view from purely a categorical and linguistic stand point. Perhaps conceptually, monism, if I understood it correctly is correct. Many come from one seems to be the way someone thinks, taking elements of the "aether" pool of conscience.
The way I thought of an object, as something that satisfies a collection of traits, doesn't necessarily imply one comes from many. If we're to see where the traits themselves are derived from, we'll eventually get to nothing, or a trait that's existing as an axiom. Square -> drawn geometrical shape -> geomertical concept -> geometry -> mathematics -> logic applied to axioms -> the concept of axiom -> nothing. I suppose you can simply choose whether those first principle sort of things are derived from an aether, or if they're monoliths standing on their own. If you view them as derived from nothing, I guess many come from one. If you view them as self-standing, one comes from many.
The choice seems kinda arbitrary, but there probably are subtle advantages, and disadvantages for having the "nothing/aether" as a thing that everything comes from, or not. There has to be an operating advantage over choosing one way of reference to the other. If, for the particular issue there can't seem to be any advantages, then it really doesn't matter. If there are, both ways of viewing things should be considered, because they may lead to different insights.
This being said. I can't really think of many examples where this abstract thing is relevant to me. For randomly philosophising, it has no practical impact. The null pointer is something where monism comes in handy.
It may simply be the case, that given how the two different ways of looking at it are not really that different, the choice where many come from one simply allows for simpler reasoning in many cases. Just imagining some sort of system where there are infinite first-principles, it may get very bothersome to reason about them in a way.
Do I have a shallow understanding of this? Yes. Do I post anyways? Yes >:).
