Having studied complexity from a computational perspective (via Santa Fe Institute and 1st wave Cybernetics) and a natural sciences one (via Dave Snowden and Alicia Juarrero) my preference is to stay away from modelling complex systems particularly complex adaptive ones. There is value in modelling, but heed the advice that all models are wrong. If you want to understand why, take a look at Steven Wolfram's Computati…

The field of cybernetics covers 100% of this context

The fact that nobody considers cybernetics an actual functional study is an unmitigated tragedy - based on politics - that needs to be fixed immediately

Wiener, etc. laid the whole thing out, gave a very compelling and clear way to approach questions and complexity, and we are just as a field completely ignoring it to our own detriment with this idea that somebody needs to invent it

my philosophical take is this all revolves around what constitues "one system" on one level, something is a subsystem of a larger supersystem on another, it's all the one and only system. but why wouldn't the components be systems in their own right? and sure, it's all about the 'appropiate' level of abstraction. but my point is that any "science of systems" must give a working theory of levels; or at least say somet…

Every book I’ve read on systems pretty much opens with exactly this point. It is merely the questions you want to ask, or otherwise your scope of meaningful control, that determines what is a suitable definition (or delineation) of “the system of inquiry.”

If that seems confusing, circular, or unsatisfactory, consider reading the work of the Pragmatists for the eye-opening revelation that this is what your brain is doing 100% of the time to 100% of your sensory input in order to make any sense of anything whatsoever.

Your perception is intrinsically linked to what you can do with that perceptual data. You separate a system from its components the same way you separate a rock from dirt, one piece of dirt from another, or soil from a tree: you do it based on what’s useful to you in the moment.

Statistical Mechanics is another good example here. As I understand it, it's what allows much of the understanding of the very early universe despite us being unable to model it explicitly or observe it directly.

I feel like any such unified theory of complexity would approach the complexity of unified field theory.

Of course you would have to model it's complexity to know with any certainty.

Yes. I'm aware. I think cybernetics has definitely drifted away from what the original scope was, also I think modern interpretations of cybernetics-ish ideas and complex system studies are slowly also incorporating social sciences and economics and so on. Interesting to note that if you look for journals on cybernetics, most papers are closer to EE, Deep Learning and some telecommunications here and there, if that c…

If you haven't already I highly recommend reading "Introduction to Cybernetics" by Ashby, it's got the nitty-gritty formalization that later "Second Generation" et. al. cybernetics drifted away from. You can get a free PDF of the book here: http://pcp.vub.ac.be/ASHBBOOK.html > This publication has been made possible largely through Mick Ashby, the author's grandson, who has convinced the copyright holders (the Ashby…

While I agree that nitty gritty formalizations are important to grasp, it's been made clear that the formal sciences were often insufficient in facilitating insight on the type of complexity cyberneticians cared about -- especially that of process oriented circular causality, which often involved paradox and self-reference.

Or Walter Tydecks on the cultural understanding of mathematics as a sign system: http://www.tydecks.info/online/themen_e_spencer_brown_logik....

> Shannon was like Spencer-Brown a mathematician and electrical engineer. In his study of data transmissions, he has demonstrated how any medium generates background noise that interferes with the transmitted characters. To this day, mathematics has not perceived or not wanted to perceive the elementary consequences of this for mathematics and logic. To this day, mathematics is regarded as a teaching that is independent of the medium in which it is written and through which it is transmitted. Nobody can imagine that the medium could have an influence on the signs and their statements. Mathematics is regarded as a teaching that is developed in a basically motionless mind.

Having taken the last 2 years to really go through the discourse surrounding second order cybernetics beyond Ashby's introduction and Stafford Beer, I learned of a pivotal text called Laws of Form, which was at the heart of second order cybernetics. The formal system was directly incorporated in Varela and Maturana's thesis of autopoiesis, and Niklas Luhmann was also /obsessed/ with Laws of Form for much of his academic career. This is a progenitor of our current interest of enaction and embodied cognition!

With the book's 50th anniversary in 2019, the discourse has been seeing a rejuvenation thanks to some small conferences at https://lof50.com. I've seen some intriguing applications. Some are a bit far out, but that's the nature of systems thinkers, yeah?

A couple that may be of interest:

William Bricken's work on Iconic Mathematics, a system that covers K-12 math and bridges it to purely physical manipulation, shedding matters of complexity difficult that fuel general mathphobia such as: associativity, commutativity, division by 0, bases, functions, order of operations, the disambiguated meaning of equality. Instead, everything is a /structure/.

Bricken's work on computational implementations of Iconic Logic. One example includes a novel SAT algorithm / tautology verification algorithm called Virtual Insertion, which makes extensive use of the notion of semipermeable boundaries, in which the context of a boundary still pervades its content.

Gitta and Ralf Peyn on FORMWELT, a yet-released system aiming to facilitate precise, clear communication of nebulous natural language concepts through the use of injunction and self reference.

> In fluid dynamics, we still don't really understand turbulence, Not to be pedantic - isn't this mathematically well described? You seem to have broad knowledge, am appealing to your insight :)

The regime change from laminar to turbulent flow is chaotic, so looking at a system in bulk will give you a decent description of the system, looking at any one part of the system will give you a random answer. This becomes problematic at systems boundaries, especially in engineering where we would like to understand the safety factor. Simulation can give you a reasonable starting place, but at the end of the day you still need test articles to see how it performs in reality.

For example, would you consider the three body problem well described? Even if it is, the solution goes chaotic rather quickly.

Great post, you're clearly on the right track. I totally agree that there is a major gap in modern theoretical understanding of how and why complex systems emerge. Breakthroughs in understanding the physical/informational processes that underlie complex adaptive systems could be immensely useful.

I'll add a word of caution though. I'm most familiar with systems theory applied to biology. Biology is, in my opinion, the pinnacle of complexity. However, it's less well acknowledged that it's also very, very complicated. This is important because it means that we have very incomplete knowledge of the base components of any biological system. Like we still don't really know the basic biochemical function of most proteins. Hell, we only just got a partial view of what most proteins even look like (in isolation) via AlphaFold. Measuring the number of all of the proteins in a single cell is effectively impossible with current and near future technology. Any feasible solution for this would probably be destructive, meaning that true time-series measurements are also impossible. These details of what we know and what we can (or can't) observe matter quite a lot, not only because they are the sort of raw matter of a systems theory, but also because they are the levers that we have to use to manipulate the system. There are only about 1000 proteins that we know how to reliably bind molecules to. There are (probably, we're not sure) more than 50k different proteins, if we include isoforms. So, all that to say, we have very incomplete knowledge of biology and very incomplete control of cellular behavior.

This isn't meant to discourage you! Instead, I think there's a tremendous opportunity for systems theory to be really useful (especially in biology) if it becomes a practical, routine analysis like statistics. But, for that to happen, we have to keep in mind the limitations and specific details of the system we're dealing with.

TLDR; we need more research into game theory

I totally agree; it all boils down to math. Linear algebra formed the foundation of a lot of what we have achieved today, including computer simulations and AI, but now society is demanding problems that aren't based in linear algebra but in game theory, as the author describes. So we need to study game theory, that's what the next period of accelerated advancement will be based on

There is an approach that I like and I think allows one to compress quite a few different description models from different domains. Take a look at this image from wikipedia: https://commons.wikimedia.org/wiki/File:Systematik-Philosoph... You see "Theoretische" and "Praktische" philosophy in the rectangle with a diagonal which probably could mean that you can sort something based on the relation between matter and information, where something is more practical and less theoretical (say 30% practice and 70% theory) add a stimulus-response diagram at the bottom and various information-material circuits inside that allow you to show how something is transformed.

There is an development of this idea from some author which leads to something like https://imgur.com/a/AmF7AJe and currently the author tries to find the connection between syllogistics, Boolean algebra, Euler-Venn diagrams, and more. You can take a look at https://www.youtube.com/@Syllogist/videos Many of the recent videos have English subtitles It's hard to describe the whole idea at once, but maybe someone will have the courage to learn something from it.

> How does the body react to imbalances in some internally-relevant biomarkers? How systems regulate themselves (and also perpetuate themselves) is the question behind cybernetics, and in the organisational context, management cybernetics. The problem generalises way beyond biology. The information theoretic and control implications are fascinating. (I’m writing a book on the subject; ping me if interested)

Yes! I think it was a parallel study between nervous systems and electrical engineering principles by Wiener et al. that kickstarted cybernetics? Interesting! Will ping you!

If you're interested in getting an introduction to cybernetics, theres:

1. Ashby's introduction, but that's from the 60s.

Foundational, but is limited to 1st order cybernetics.

2. E. W. Udo Küppers, A Transdisciplinary Introduction to the World of Cybernetics (2023): https://link.springer.com/book/10.1007/978-3-658-42117-5

Provided a broad picture and basic intro to the history, central concepts, and various involved thinkers involved.

3. Stuart Umpleby's 6 hour lectures on the Fundamentals and History of Cybernetics (2006): https://www.youtube.com/playlist?list=PLB81F4FC0EDC4DECC

Provides a historical overview and introduction to applications of cybernetics in social sciences.

Crucially, Umpleby's history mentions the exact reason why Cybernetics never quite took off in America (well, aside from the fact that it was just difficult to fit into a disciplinary box). Heinz von Foerster, head of the Biological Computer Laboratory, did not want to provide a b.s. military justification for Dept. of Defense funding after the Mansfield Amendment -- (which, was passed in response to student protests of divestment from the Vietnam War).
