Young" <34LPF6T@CMUVM.CSV.CMICH.EDU> Subject: Re: Causality, Chaos and Postmodern Phil/Sci To all gradual students in sociology [love the phrase, Michael!], my reply to Michael Licter's questions re: Chaos/complexity theory follows. First, Chaos theory is a very technical theory based upon the nonlinear dynamics of a very deterministic algorithm...that is, two or more complex numbers which, when feedback into the result of earlier interaction, produce a very regular transformation from order to dis- order. Complexity theory deals with much more complex feedback loops...the same nonlinearity is found but is much less 'deterministic,' i.e., it is much more difficult to discover the algorithm [s] which produce the leaps, turns, twists, jumps and otherwise unexpected patterns of events. Whether the same elegant patterns found in simple chaotic regimes [modelled by the bifurcation maps so often seen in the literature], are to be found in social dynamics...that is still an open question since the basic research is not in place. I tend to think that much of the things one can say about simple chaotic regimes will be found to be useful in sorting out the generation of, say, new forms of crime, new forms of gendering, new forms of marriage/cohabitation, new forms of racism and new forms of religion. There are two pieces of work which tend to confirm that suspicion...first there is the work of Dr. Patricia Hamilton and her colleagues at Texas Woman's University...they have found two hidden attractors [fuzzy patterns] in a large data set from records kept by the State of Texas on births to teen age women. They are now looking for the factors which produce each attractor. Then too, there is the work of Brian Berry at U/Texas, Dallas who has reported that both the 50 year Kondratieff cycles and the 15 year Kutznet cycles behave nonlinearily. ----------------------------Original message---------------------------- T.R., et. al., My understanding of Chaos Theory (CT) is that it provides a framework for understanding the complex behavior of *deterministic* (physical) *systems*. Even relatively simple systems which operate according to fixed rules can display complex patterns of behavior which are for all practical purposes unpredictable. Ben Goertzel (Ted's son) calls choas "deterministic unpredictability." My question to you is: are you arguing that human society (or some subset thereof) meets the assumptions of CT (that it is a chaotic system in the CT sense), or are you saying instead that while human society is not a CT-type chaotic system, CT can help us imagine explanations for social phenomena? Ans: The later more than the former would be my present position until we have a lot better reading on these nonlinear dynamics. Personally, I think that if anything is non-deterministic, then human behavior is. I am skeptical that CT has anything to offer for understanding society because society does not operate according to CT rules. Ans: I too, think that human/social behavior is non-deterministic in the sense that causality opens and closes. I made that case in an article in Humanity and Society a couple years ago...entitled Chaos and Human Agency...I made the case that, at any scale of observation, certainty was replaced by variety...that in complex dynamics there are moments when human agency [esp. collective human agency] is possible more so than at other time...the interesting thing to look for/at is whether there is 'pattern' in the cycles of freedom and necessity which catch us all. I'll try to keep members of socgrad up to date on new evidence to Michael's questions as I hear from those active in the area. I will teach [post- modern symbolic interaction/social psych at TWU beginning in Jan. and will be able to follow the Hamilton research closely...it is, in my considered opinion, very important. Thanks Michael, for the questions. T.R.Y. P.S.: I've met Goetzel's son, Ben...he was very good at the third annual conference on Chaos/Complexity in Canada...Ted tells me Ben moved to New Zealand...our loss, their gain. -- Michael Lichter -----------------------------+ Department of Sociology | University of California, Los Angeles ---------------------------------------+
