Now you're saying that a bikini isn't self-organizing. I find this obvious at first glance, but it becomes less obvious when I look at divisibility: A bikini is already divided to begin with, in a physical sense, and is only a whole on a social background. Other clothes follow this pattern: shoes, socks, gloves... the bikini stands out by not being symmetric. So we sell pantys and bras seperately, but we sell bikinis as a unit?
Artifacts are an interesting case because they are organized around a purpose, it's just that their purpose is extrinsic to them. The goals and purposes attached to them is not essential to what they are, rather their form is a function of their intended use. They can be very complex (e.g. a self-driving car), and could conceivably be designed so as to try to maintain or replicate their own form in the ways organisms do (although this goes into the realm of sci-fiction), but they lack the intrinsic goal-directedness of organisms.
Now, something like a synthetic lifeform would be an interesting case here, since it would be the product of goals and intentions, but also have its own intrinsic goals and intentions. However, I don't think such a thing is actually all that novel. We have bred domesticated organisms in this manner for millennia and people are obviously (more or less) intentional about who they chose to have children with. Eugenics wasn't a wholly sui generis innovation either.
I'm thinking it might be useful to think in terms of system-integration, here, too: while we may be self-organising in terms of being an organism, we're not self-organising in terms of society, so we're not necessarily self-organising in the subsystem that includes bikinis. But that we're self-organising as organisms is part of the way society self-organises. So a bikini is only a bikini within the context of a self-organising system (such as society) that also includes us.

Somewhere, St. Thomas says "all the efforts of the human mind cannot exhaust the essence of a single fly." Things are not only always changing, but they can always come to exist in new contexts. This is as true of things as words. Robert Sokolowski says something similar about never being able to "fully grasp" the intelligibility of things, but of course we can grasp them more or less well. So, the establishment of substances (things) in metaphysics isn't, in my view, about offering something like an exhaustive account (impossible) or some sort of unique lookup variable or set, but avoiding the slide into "everything is context all the way down," viz. "either there are no things, or else an infinite number of different things superimposed over any thing."
Societies and other human organizations are self-organizing to some degree. They can also become more intentional about how they develop themselves. Data collection, analytic departments, etc. are in some sense the "sense organs" of a state or corporation. Yet states and corporations presumably don't have experiences, goals, their own desires, etc. So they are an important sort of thing in the world, but their being is parasitic on people.
I don't think it's any surprise that we see a slide towards "there are no things," in the modern period. The successes of mathematical physics have led to attempts to do philosophy without taking any account of the phenomenological aspects of being, essentially pumping all the subjectivity out of an account of the world. This occludes the obvious existence of individuals in terms of ourselves.
In other words, reference needs to be inscrutable on the organism level, as organisms aren't made to operate on higher organisational levels.
I wasn't sure exactly how to take this. My position given earlier in the thread is that elimination arguments from underdetermination are not good arguments. Showing that something is underdetermined doesn't demonstrate that there is "no fact of the matter." Such arguments don't just affect reference, they work just as well vis-á-vis the validity of induction, all scientific knowledge, all historical knowledge, etc. Are we to also maintain that there are "no facts of the matter" because these are underdetermined? That seems like an absurd conclusion to me. For example, that there is not "no fact of the matter" about who won the last World Series simply because all of my (or anyone else's) observations might be consistent with there not having really been a World Series last year. The focus on reference obscures how widely virtually the same argument can apply.
I don't think even merely skeptical arguments from underdetermination account for much. They amount to "you cannot know whatever you can imagine yourself to be wrong about." But we can imagine that we are wrong about anything.
And there maybe some kind of analysis for this regarding how systems or things nest within each other in a statistically meaningful way, like the human use of bikinis as opposed to sme other properties / lack of properties in a flout. Ofcourse this is all just complete speculation whether this kind of analysis can even coherently be done in this kind of framework at all. I also suspect you could probably get some unintuitive results, but I guess it just reflects how my attitudes and inclinations would want to approach this kind of issue ideally.

The "nesting" is indeed interesting. You have subatomic particles in atoms, atoms in molecules, molecules in organelles, organelles in cells, cells in organs, organs is bodies, bodies in communities, communities in ecosystems, etc. From an information theoretic perspective, you can see this in the way you can measure a message but also measure the substrate it is encoded in. Terrance Deacon has some interesting stuff on the relationship between physical entropy and Shannon entropy.
I think metaphysics always has to be from the purview of what we perceive, so notions independent of that don't mean much. I think the most generic, fundamental way we can talk about the universe is that it has structure - we just want tomake our organization if these structures coherent from our perspectives in a way that is informative to us, while acknowledging all the caveats.
Indeed, and presumably there is a causal explanation that can be had for the phenomenological experiences of beings (plural), even if it is imperfect. Sometimes explanations of these sorts seem to err by only looking "inside the brain," though. However, no perceptions (or consciousness) occurs in a vacuum and all the evidence suggests the properties of the objects we perceive is constitutive of perception (e.g. leaves look green because of their composition, not just because of how our eyes work, but the interaction of the two, which is how Aristotle saw things).
So, to return to signs, C.S. Peirce and John of St. Thomas had it that the causality proper to signs was to make us have one thought rather than any other. "Fish," makes us think of fish, dark clouds and low pressure cause us to think of rain. This could probably be explained in other frameworks though. Obviously, it is dependent on learning, although I don't think it can be reduced to just correlation, since there is a phenomenological component.
The idea behind P3 is that eliminativism is more parsimonious than its metaphysical rivals (conservatism and permissivism). Its ontology has fewer elements.
An ontology with just one thing (or nothing!) would be more parsimonious. But this seems to me to be in the vein of the eliminitivist who wants to get rid of consciousness because it messes with their models. If you're ontology doesn't describe what there actually is, what good is it for it to be parsimonious?
So "insect" unproblematically refers to the set of all insects? But then "gavagai" can just refer to the set of all rabbits. And "the rake in this room" just defines a set with one element. Hardly inscrutable.
At least until we get to the solution of defining the set where: "insects are just whatever we want to call insects." "We" collectively of course, because if meaning has anything to do with a speaker's intentions we will have Humpty Dumptyism, yet if we multiply the problem it vanishes.
And also "insects existed before anyone was around to want to call anything by any name," even though what an insect is remains entirely dependent on how humans use the token "insect" at present.
I think this might also be problematic. If "what a thing is" depends on what we decide to count it as, then at one point in the past, carbon dioxide and carbon monoxide were the same thing, being indistinguishable. Then we distinguished them, and they became two different things, but in a sort of retro causal action, it also became the case that they were always two distinct substances. Or perhaps the same words just refer to different sets depending on current usage?
If that's the case though, then even "what counts as a set" is always subject to revision. If mathematics changes, then what will have been a "set" will also change, since what things are is what we decide to count them as. And in this case, I don't see how it won't be the case that every proposition isn't subject to having its truth value change.
After all, the "things are what we want to count them as" solution implies that when the use of "insect" changes, what insects are changes. But this entails that what is actually true of insects, sets, extension, reference, etc. is also subject to change. Not only will it be subject to change, but the change in truth values will reach backwards in time. For instance, if we decide to count giraffes as insects, they will have always been insects.
That seems problematic to me. It's Humpty Dumpty just scaled up. Now, you might say "but we wouldn't ever call giraffes insects." And I'd agree, because language admits of causal explanations, which you've tended to denigrate in the past. But, IMO, that's what is at the heart of all scientific explanations, a grasp of causes and principles.
