[ph] As I was saying, my interest in using math to explore the environment rather than represent it. So my use of the math would be to frame the question and point to where the answer might be found more than provide the answer. I was just posing the classic question of a simple physical object that is easy to describe but in a description that is stripped of our cultural associations as math is, the description of the object itself would not contain any reasonable hint of what it is for. The question then might be rephrased, what kinds of mathematical descriptions contain a hint of what the thing described is for, linking it to it's context? The main one I use is the continuity of a thing's changes, because how something changes over time connects it with its context. The curious thing is that the math of history curves is thought to be mathematically more or less meaningless but, potentially, accomplishes the bridge across the gap that makes 'meaningful' math self-referential and disconnected from reality. It's not 'buttons' we're so concerned with, but networks as complex systems, that when described as a stand-alone diagram are abstracted from their context, but as a history of developments are connected to their context. > > -- > glen e. p. ropella, 971-219-3846, http://tempusdictum.com > > > ============================================================ > FRIAM Applied Complexity Group listserv > Meets Fridays 9a-11:30 at cafe at St. John's College > lectures, archives, unsubscribe, maps at http://www.friam.org ============================================================ FRIAM Applied Complexity Group listserv Meets Fridays 9a-11:30 at cafe at St. John's College lectures, archives, unsubscribe, maps at http://www.friam.org |

We have not formalized this hopping about, but it surely is formalizable. We humans think we can hop about as we like because we live in tightly constrained environments (our universe, more specifically Earth, heavily industrialized/civilized/conformed to primate living requirments) - I would guess our cognitive systems would crash if sufficiently alien environments were provided (probably dropping you on Pluto in a spacesuit would be enough to make most people go insane).

I (in my more reductionist moments) reject that, too. I'm not claiming that there is anything _other_ than formal systems. I am claiming that somehow ... I don't know how ... humans can put on and take off different formal systems as if they were hats or shirts. When we hop out of a formal system (into a different formal system) and begin counting the sentences in the first one, we are doing something that we can't (yet) mechanically automate. But we are _still_ engaging in math. (Witness "model theory".) > Yes, very interesting, this hopping is just what would be required! But > I think in computer science just this is being done!

It seems to be > difficult *grin* Right. We _do_ this type of hopping around all the time in math and computer science ... in fact, we do it all the time even psychologically. (I think it's what allows people to hold strongly to obviously contradictory or incommensurate convictions.) The trick is that we don't have a full-blown _measure_ (or better yet, metric) of the set of formal systems and a grammar for hopping in and out of them. Again, I have to qualify that with "as far as I know." There could easily be whole branches of math I've never run across and perhaps they do exactly what I'm saying hasn't been done.... for all I know. Now, I don't know if I'd go so far as to claim that obtaining such rigor for a description of "formal systems space" would solve the problem of artificial (general) intelligence. But, it would help us build robots smart enough to do the general work that can be done by most humans. Designing a robot that could adopt and abandon formal systems when its interactions with the environment start to go wonky beyond some threshold would definitely go a long way to achieving general intelligence. Of course, I don't believe that's possible in the _abstract_, though. As I've said before, I think the ability to don and doff formal systems goes hand-in-hand with our embeddedness ... the fact that our CNS is concretely embedded in the environment via continual, real-time, sensory motor feedback loops. Without such embedding, I don't think we can construct robots that don and doff formal systems at "will." >> No matter how high or low in the hierarchy you may go, you will still be >> using math, but you will not be locked within any given formal system. >> Hence, math is somehow more than (or outside of) formal systems. > > Here I disagree - you are reifying the word "math" - but the collection > of all formal systems is not a thing which is good to speak about I think. > > "the dao that is named is not the eternal dao" ;-)) [grin] "Good"?? Why wouldn't it be good to speak about that collection? Do you think it's ill-defined? I admit that it's vague and that I'm just yappin' without making any significant contribution... but I don't think it's necessarily "bad" to talk about such a mathematical object... even if it's only hypothetical. I take heart from things like universal algebras that we can make progress. But, then again, I'm an optimist. I'm hoping that you mentioned the loopy nature of taoism purposefully. There's a lot of deep analogy between assuming a fixed formal system (reductionist -- guilty of the fallacy of the perfect solution) versus allowing math to contain some ill-conceived "glue" between formal systems and Western versus Eastern thought. But, again, the path to enlightenment usually involves being swatted upside the head when you ask or attempt to answer a loopy question. That swat in the head that you get from, say, your Zen master (now only $39.95 from your local Wal-Mart! ;-) is a reminder that the answer lies in the sensory-motor coupling between inferential and causal entailment and NOT isolated on either side. > We have not formalized this hopping about, but it surely is > formalizable. It may not be formalizable. ...

So I think this "unmechanistic" jumping is an "inside view" > cognitive illusion. I'm not so sure. I think there is plenty of inter-individual variability between humans to argue that _some_ people would go insane if they were dropped on Pluto but others would not. Whether the ones who go insane do so because they believe in a universal formal system or because they flip out in some runaway hopping process is another more refined question. Ultimately, given my previous opinion, if they go insane it won't be because humans _need_ some fixated formal system. It'll be because living in a space suit with no other living beings with which to interact would be an extreme abstraction from the necessary sensory-motor embedding we all use. > So, we have the hypothesis that in the end it all boils down to formal > systems (=mechanism; which is nicely defined via computability); > or that it somehow goes beyond the formal - but what should this be?

This is a deep principle, > requiring much thought. I would like to end on this philosophical note. > Thanks for your remarks Glen, very stimulating! Yep! That's a good place to end... in spite of all my rambling above. Ultimately, when big weighty principles like that enter the discussion, it's usually an indicator that we've traveled very far down the rabbit hole and any further descent will be useless (except for mumbo-jumbo mind expansion ;-). Regardless of whether or not the universe is ultimately mechanical or not doesn't remove the (apparent) fact that lossy compression (as in a human's understanding of the world) is useful for prediction. So, in the end, even if everything's ultimately mechanical, there's still a place for things like "magical thinking", wisdom, and intuition. Hence, it's down right silly and wasteful for die-hard reductionists to spend so much time brow-beating the holists. And thanks for your patience and vision. Normally, people just call me a silly person and walk away.

I agree that your syntax must be somehow inadequate to cause you to look outside of it. And, if we believe his argument, Rosen's work culminated _merely_ into a demonstration of how our modeling language is inadequate. (Not to belittle that achievement, of course.) He didn't really get very far in extending the language so that it could capture (Rosennean) complexity.

We could easily fall back into a dark ages where, say, Monsanto, specified what we consider "biological truth". So, it would be nice, but perhaps logically impossible, to construct a really _reliable_ procedure. -- glen e. p. ropella, 971-219-3846, http://tempusdictum.com ============================================================ FRIAM Applied Complexity Group listserv Meets Fridays 9a-11:30 at cafe at St. John's College lectures, archives, unsubscribe, maps at http://www.friam.org |
Glen,
You say "But, I'm not sure that "having clues to where to look for discoverable things" is a reliable procedure. That sounds pretty ad hoc. If I were to attempt to create a reliable procedure, it would invariably involve some concerted (and distributed) hands-on effort to explore reality. In fact, I can't think of a better method than what we're already doing in science today." It's odd that you don't catch my intent to help others understand a very non ad hoc and efficient method, not yet in general use, for doing just that. To understand my technique you do need to distinguish between information and the physical prosesses from which we get it.. That can be a hangup. Once you distinguish between those, what works to let your information signal you where to look in physical processes for better information about how they work is the transitions between continuities. That indicates transitions in how they are working, giving you focused questions and a subject to closely examine for more. my site is a bit of a mess, but you might think of it as all about the progressions in the continuity and conservation of change that signal where to look to see how complex developmental processes work.

I'm a bit of a literal person and, since we were talking in the context of Rosen, I keep trying to tie the conversation to what I understand of Rosen's work. And in that context, we're (or should be) assuming a very clear delineation between causal and inferential entailment, a.k.a. "physical processes" and "information", respectively. So, at least in the context of Rosen, that distinction is not the problem.

Well, of course "having clues to where to look for discoverable things" is not a reliable procedure ...if you simply speculate. It's like offering someone in a clue to where the beer is.

Glen,
Oops, please ignore last quip, a response to an old email having had a couple extra beers... My technique is for identifying where physical systems beyond our information are located, and then how to explore them for interesting information. I guess the way that relates to Rosen is as what you should do if you accept his conclusion that math is inadequate as a representation of real complex systems. The alternative I'm suggesting is that you let complex physical systems represent themselves, and use the math for the purpose of exploring them instead. Yes... it turns the world on it's head in a certain way, or backwards if you prefer, but it sure works better that way when it comes to systems that distinguish themselves by developing in individual ways along paths they find by exploring environments there's not way to describe. That's why I switch from a representational objective to an exploratory one.
