I feel that I should make an attempt to respond to three emails of Mr. Landon. But I will have to be brief because this is an extremely complex topic. However, for those interested in related topics I will point out this reference: Hubey, H.M. "Evolution of Intelligence: Direct modeling....", Kybernetes, Vol 31, No. 3/4, 2002. >Date: Mon, 21 Oct 2002 22:09:07 EDT >From: NemoneminiMail to author|Respond to list|Read more issues|LINGUIST home page|Top of issueaol.com >Subject: Re: 13.2704, Disc: Darwinism & Evolution of Lang > >>Actually this is simply a matter of definition.

csam-lists.montclair.edu, and in the body of the message put "subscribe language" (without the quotes). What is randomness and what is deterministic is very clearly defined and I wrote it above. No need for confusion. >Date: Mon, 21 Oct 2002 23:43:49 EDT >From: Nemonemini

And soon I will be working on "population genetics" models with a colleague whose specialty is dynamics (in fact, population dynamics) and we will be working on language evolution. To add more, the partial differential equations for the pdf (prob density function) of random processes are the so-called diffusion models, and I have already done work in this field and understand it reasonably well. You can also read about them in both of these books: Hubey, H.M. 1999, Mathematical Foundations of Linguistics, Lincom Europa Hubey, H.M. 1994 Mathematical and Computational Linguistics, Mir Domu Tvoemu, Moscow (this later published by Lincom Europa in 1999). Longer and more detailed versions of these books (with examples and exercises suitable for teaching) will be eventually published. >Consider finally a puzzle.

It is exactly because it is so difficult to explain that so much precision and detail are needed. There are tons of mathematical materials on probability theory, stochastic processes, plausible reasoning (See Jaynes' book), etc. It is a very rich field and also very powerful. Today most of datamining, model-building, search for patterns, knowledge discovery are all tied together within the view point of probability theory, namely Bayesian reasoning. See the book by Hastie, Tibshirani, and Feldman for the last 30 years of research in this field.

Give me a reference to something here. There is always an outside chance some kind of stochastic model like this might have a partial application to the type of thing pointed to in the eonic model. However... Consider a case where a similar phenomenon has an effective method, e.g. the study of economic cycles. Instead of modelling some 'economic phenomenon' with a predictive or control model, we stand as immersed agents in the present looking backwards at any structure characterizing free activity, economic cycles. Whatever their 'causes' we remain, within limits, free agents able to reapply this information about the past form the present onwards, e.g. modulate a slump. We have the ability to modify the system based on new information. This simple fact puts the subject forever beyond the standard type of analysis. I was reading a recent book on long waves and Kondradieff. The author complained that Greenspan wrecked his predictions! Apparently Greenspan saw it coming and changed course. Etc... The eonic model is like that. So we need a model that clearly partitions the past and present. How do that? My type of discrete-continuous model is built around that, all dynamics is about the past, then the model changes character in the present and we have free action. Such things aren't weird, but ordinary. Consider a computer (determinate program) and a user with a mouse. Exact type of situation. How does it work? The determinate system alternates with the user, or free agent, whose input is a series of options, while the system responds with determinate programming. This mixed model is clearly evident in history, as we look backwards. Note that we can study the history of this interaction, it would be determinate interval, free option interval, one after the other, with the user's present openended. The eonic model reflects that. Lo and beyond if we examine world history we see this alternation of degrees of freedom between a higher determination, and a relatively free optionality. There are two things at work, then. And the free agent does not attempt to predict his future based on the system, but to increase his freedom in that system by using information he has learned from experience, information he will use to _exit_ that system. It is an odd type of model, at first. We simply aren't in the realm of physics here, although cousins of physics models are evident. But they reflect the exact statement, by the way, of Kant's Third Antinomy, which see. That antinomy is broken into two parts, one determinate, one relatively free!! It's a small world. And this is quite natural, but the core is a contradiction. Now we see why social science never starts, never could start, because its basis is a contradiction, an antinomy. And yet it can start at any time, by embracing that contradiction. This may be the last series the moderator wants here on this. Let me say I am gratified by the response to the webpage on the eonic model. It takes a knack to get used to it. The original relevance to linguistics was indicated in the language transformatin at a very high level indeed in the Greek Archaic, justy to remind ourselves of the fact that we are still inside evolution, and that even things at the level of art show, not deterministic generation, but just this kind of combined determinate-optionality indicated. The core pivot of action then is the creative gesture of the evolutionary transition, i.e some distinction of consciousness and self-consciousness. Determinate models don't really work because it is like sheep herding, pushing a crowd, so to speak. We see evolution over a stupendous scale doing sheepherding 'soft push' dynamics. It operates at a minimum of interaction. Science Fiction? Look at the data in the light of a very simple scheme of periodization. Then what used to be called the Axial Age stands out for what it is. But its implications are remarkable. Genuine macrodynamics right under our noses, looking backward. Again, let me express my skepticism about Darwinian explanations of the emergence of language. They probably don't work. In fact we have no data. The example of the Greek Archaic shows that highspeed evolution leaves poets in its wake. So we must have missed something. Thanks. Lots to say here. But enough. I hope the model indicated at http://eonix.8m.com/enx_theory1.htm will prove helpful.
