You really are just another filosofeezer, aren't you? All you have is an ideological axe to grind.
That may seem fair and it may even be fair although it utterly misses the point. It is not me telling anyone else here what the approved dogma is. That is what I am objecting to and that is what you are doing.

And you gave me a puff piece. That's not a basis to regard you as anything but a filosofeezer.
Well, I am not asking for anyone to take me as an authority. I study people and work with a broad cross section of disciplines. In the past I have done a fair amount of GIS work mostly involving population modeling as an intersect. I use a few very narrow machine learning tools involving topic modeling and sentiment analysis. I use STELLA systems modeling tools for a specific and also narrow set of circumstances. I have used some agent based models in R but would not consider myself particularly proficient other than knowing what it it used for and what I could do with it given a strong enough need. R is not a strong suit of mine. I have done a great deal of social network modeling using R packages but eventually switched to Pajek since my needs were quite limited and R is a constant learning curve.
I tend toward a systems approach because the questions I am asking lend themselves to a systems approach. If you care about community resilience and social capital in public institutions, especially city government, education and healthcare, I can answer quite a few questions with informed, though not dogmatic, opinions, as well as point you to lots of source material.
I can tell you that emergence adaptation and fitness landscapes are central to the questions I am interested in. I can tell you that previous frameworks for addressing those questions have led to quite well known problems which are now the central questions confronting the field I am in and that those same problems have analogs in pretty much every field so there is a trend toward cross-discipline work and the Santa Fe institute has been a very important part of that trend. The reason emergence is a buzzword is that it describes the central issue confronting anyone who is trying to understand adaptation and change in open systems which is almost everyone, as was stated in the "puff piece".
So there, now that we have dispensed with the authority issue, let's look at the puff piece:
When electrons or atoms or individuals or societies interact with one another or their environment, the collective behavior of the whole is different from that of its parts. We call this resulting behavior emergent. Emergence thus refers to collective phenomena or behaviors in complex adaptive systems that are not present in their individual parts.
This means that if we want to study adaptation where future system states in open nonlinear systems have qualities not present in current system states, navies stokes is useless. So, for that matter, is almost the entire rest of physics and math.
That presents a puzzle and justifies, imo, the work being done to find a nomenclature that allows researchers to generalize within that problem landscape.
Examples of emergent behavior are everywhere around us, from birds flocking, fireflies synchronizing, ants colonizing, fish schooling, individuals self-organizing into neighborhoods in cities – all with no leaders or central control – to the Big Bang, the formation of galaxies and stars and planets, the evolution of life on earth from its origins until now, the folding of proteins, the assembly of cells, the crystallization of atoms in a liquid, the superconductivity of electrons in some metals, the changing global climate, or the development of consciousness in an infant.
So, there is a series of examples of questions which have proven amenable to a systems framework. Neuroscience specifically almost entirely frames the field in emergent terms. I know this because a very good friend of mine is a neuroscientist and we have had long discussions about it. If you would like to read some of those, I can provide links.
Indeed, we live in an emergent universe in which it is difficult, if not impossible, to identify any existing interesting scientific problem or study any social or economic behavior that is not emergent
Here is a strong claim. But the universality he describes would not water down the utility. Rather it would be a strong case for more work on the epistemology, the philosophy, of a systems paradigm.
If indeed, using a systems or emergence oriented paradigm does offer a better way to visualize the problem space and suggests new approaches to problems through that framework, and if those newly framed problem spaces do indeed give up new secrets and useful knowledge, then it is a justified buzzword, even though the nomenclature is still fluid.
And, surprise surprise, it does. Neuroscience, as one example, would erase the past maybe 20 or 30 years of gains were we to eject the framework. Deep neural nets, as I mentioned earlier, possibly and even probably the most profoundly transformative science in the history of humanity, would be out. Economics would be back at Milton Friedman and supply and demand equilibrium concepts, so 20+ years back. Social networks would be incomprehensible. I mean, as I said several posts back, your ignorance is not my problem. This "puff piece" does a pretty good job of outlining why emergence matters and what kinds of questions it can help us ask and answer.
Notice that I have not asked you what your authority to toss out navier stokes as some kind of meaningful objection is? It's because I don't care. How about explaining why it seems like a gotcha to you?
I am happy to discuss pretty much whatever with as little ego involved as possible, but your apparent need to be the gatekeeper on what questions are acceptable and what philosophy is legitimate is not very compelling to me.
BWE wrote:They do not start with perfect data and they are nonlinear. They are subject to the butterfly effect.
Somebody who read James Gleick's book thirty years ago would be able to say that. Enough boilerplate, Mr. Filosofeezer.
Why does the fact that it has been known for several decades discredit it?
BWE wrote:I think there is a good reason to think of fitness landscapes as a continuum marked by a series of phase changes where different kinds of complex processes begin to emerge and that life is viewable with exactly the same validity at multiple levels. I have what seem to me to be good reasons to think there is value to viewing changing environments that way. You on the other hand seem to feel that if those reasons don't fit your pathetic little reductionist boxes, they don't exist.
Did I say anything about hewing to some reductionist paradigm? No, you projected that into what I wrote because you have a silly political axe to grind. Meanwhile, bleeble-bleeble continuum marked by a series of bleeble-bleeble that bleeble multiple levels. And bleeble bleeble changing environments. Minus the specifics. Grind away, axe-man.
Why yes. Yes you did.
BWE wrote:I suppose deep neural nets are just a fad. Damn but you use your ignorance as a shield to protect you from thinking any new thought ever. That is the tip of a gigantic iceberg and that tip is probably the most important (in terms of impact) product of science in the history of our species.
Promises, promises. Tell me what's been done, but especially, tell me what you've accomplished with them, or are you just another cheerleader in the blogosphere? Will it be the tip of a gigantic iceberg? It won't be nothing, but it won't be the most important tip in the history of our species that you can demonstrate. I'm not denying you your shot.
Wait, are you really asking me to tell you what is being done with deep neural nets? Just Google "AI". Controlling pretty much every dynamic resource, from power grids to oil pipelines, to deciding who gets bail and prison sentences, to writing content for public consumption across all media channels, to regulating activity across capital markets and banking, to basically every damn aspect of 21st century society. I mean, that's a remarkably ignorant ask. Especially since it's a) a major news topic, and b) so pervasive that almost every discipline in existence is being transformed by it.
BWE wrote:You cannot fathom that there could ever be any way to look at things other than the way you look at things.
Because I won't genuflect at the feet of some puff piece, and more inflated promises?
Who asked anyone to genuflect? But that is nice of you to provide such a concrete example of acting as a gatekeeper. I personally am heavily involved in using a systems framework and it is simply a fact that so are significant numbers of people across most disciplines. Some disciplines have almost exclusively made their recent gains within that framework, examples listed above.
But again, to circle back around, none of this is relevant to whether or not evolution can be usefully viewed as a continuum marked by emergence of pattern types. It can and it regularly is. Darwinian selection is a subset of adaptive evolution but it does generalize quite usefully to other kinds of adaptive processes and so, in the entirely subjective matter at hand, it is not wrong to say what Paul is saying. It is convoluted and has more emotion than structure most of the time, and lots of what he says in support is probably wrong when it even makes sense, but it is fair to say that emergence or some other idea closely associated works as a general framework within which evolution is the method a model follows.
Do you accomplish anything, or are you just going to proselytize for something you've turned into a personal religion, trying to win hearts and minds? Link to some fucking technical article that shows work you think is important, or do you just assume I won't be able to read it?
At this point, I assume you won't be able to read it.
BWE wrote:This bubble you are in is toxic. You've defined the questions it is allowable to ask and have forbidden zones. That is also called religion. Jesus christ, you'd think just the realization that time and space are relative to an observer would be enough to make you realize how utterly provincial your ideas are. Maybe it's the church of atheism shtick has made you see creationists and woo in everything outside your tiny little bubble: out there be dragons.
That isn't why I'm dismissing your bleeble-bleeble. If you know what you're talking about, you'll do better than emitting polemic. Do you sweet-fucking-know what you're talking about, enough to make the sorts of promises you're making? I don't think so. At best you'll have some abstruse little squiggle of specialist research that doesn't translate into making history, or else you'd be telling a more important audience about it, you know, like David Pines did. Tell someone else to fill their boots.
Lol. Again, you are asking me to clear your philosophy gates to achieve relevance. I'm not proselytizing. The work I do is classified as social science. I am not in the habit of trying to justify a discipline to those who've already prejudged it as illegitimate.
Just read a nodern neuroscience text.
