[FRIAM] More on levels of sequence organization

[uǝlƃ ☣]

Thanks VERY much for posting some digested material from the paper. What you say below seems to hearken back to what JonZ (or maybe JohnK?) said awhile back, ... paraphrasing: that he would be hard-pressed to find something that organisms can do that can't be duplicated by a sequential machine.

That type of statement and yours below do not *imply* that an effect was NOT generated by a (semi)hierarchical structure. It merely implies something like the parallelism theorem, that anything a (semi)hierarchial system can do, a "flat" one can do (though perhaps with extra space or time costs). Am I reading your statement right?

They take the levels of organization as known facts and construct observations of the model that make predictions consistent with the levels.  So if there are levels of organization as yet unidentified, they are at least as obscure in the model as they are in reality.   And to claim that the levels of organization emerge from the model sort of ignores how much work went into constructing the observations.
