Re: [Fis] Fwd: Re: Fwd: Re: Concluding the Lecture?
Dear All, RE: Steven Ericsson-Zenith (I am not sure that your comment was posted to FIS) The phrase "dynamical constraint" should not be that unfamiliar or difficult to parse. Constraint on the degrees of freedom of a dynamical system is the most obvious (and the meaning that I have in mind), though I suppose that there could also be other meanings that are possible (such as might characterize the increase in convectional correlation in the formation of Bénard convection cells). I don't see that the notion of constraint need be restricted to some extrinsically imposed static boundary condition. As far as I can tell, this concept is quite unrelated to my friend Stu Kauffman's use of "Yuk or Yum" (a normative—not physico-chemical—distinction), which of course can only apply to something like a living system that is organized to perpetuate its organization by utilizing external resources and avoiding dangerous extrinsic conditions. Indeed, I believe that my simple model of an autogentic system provides an unambiguous description of the minimal dynamical system organization necessary to determine a self/environment relation that embodies an intrinsic good-for/bad-for valuation. In any case, I don't see any reason to think that my use of the concept of dynamical constraint, or constraint in general, to explore the nature of information and agency should imply that this is a case of "posterior determination" rather than an acquired disposition that organizes an autonomous agent's adaptive responses to extrinsic conditions. I hope that this clears up any confusion that my use of this term evoked. RE: Joseph Brenner I think that we are largely in agreement. And I think that you accurately locate our differences in how we understand the contribution of quantum-atomic-molecular properties to these dynamical properties, and to the relationship we call informational. I am generally of the opinion that non-classical quantum effects percolate up to the molecular scale and higher only if very special conditions prevail (such as in photosynthesis), and that otherwise the statistical nature of these influences results in canceling effects. To me it is a bit analogous to the classical vs relativistic distinction in which at mesoscopic spatio-temporal scales (and well below c) relativistic effects can be neglected without any significant error effects. But I agree that this means that (in principle) both extreme scale effects "can sometimes" be relevant, and are ultimately part of the complete picture. I just don't see how these effects change the dynamical system requirements that determine how a relation of reference or significance is intrinsically established for that system (i.e. IN and BY that system independent of this being assessed by an external "observer" - whether explicitly or implicitly). As to the various interpretations of the quantum measurement problem, I also agree that my view is not the mainstream view, but it is not purely idiosyncratic either. There is more work needed here. For me, to make the claim that quantum indeterminacy is the "... foundation of the dualisms at higher levels of reality" abandons the most interesting game in town by just positing its irresolvability. To me this just ends inquiry into this interesting mystery by invoking another mystery that is claimed to be irresolvable. I take the view of Richard Feynman who said about quantum physics "... I don't understand it. Nobody does" — by which he means that nobody has a clear idea of why it must be the way it is. I am skeptical of those who claim they know, or know that it has no deeper resolution. In this respect, I am comfortable in my minority opinion. But disagreement at this most basic theoretical level doesn't undermine our ability to come to a convergent understanding of many of the higher-order phenomena we have discussed, including the organization of dynamical systems able to intrinsically determine the reference and significance of information. In this and other arenas I look forward to interesting critical debates to shed more light on these concepts.

[Fis] Fwd: Re: Fwd: Re: Concluding the Lecture?
Dear All, I would like to thank Terry for his detailed analysis of my comments on his work. I should repeat that I consider his theory as a necessary part of any emerging theory of information and going beyond Shannon. I also commend him for indicating where it is 'incomplete' (sic), subject to differences of opinion as to what may be relevant from other approaches which have not been explicitly discussed in his paper. One interesting place to start might be the following statement by Terry: "Only the linkage between them (JEB: the molecular phenomena of the model) that constitutes autogenesis lacks a known empirical exemplar. It is an empirical question whether this can occur, and what conditions and types of molecules this would require. I see no physico-chemical reason to doubt this possibility." According to my view of real molecules as instantiating both actual and potential properties, the linkage between them does also. If this picture is correct, we have a correct way of looking at the phenomena themselves. We can then accept the value of the model, which does not violate the principle but ignores it, but not forget this additional principle when returning to reality. My view is, admittedly, dependent on acceptance of the reality of quantum entities and their most complex (non-Boolean) properties as the foundation of the dualisms at higher levels of reality. However, I believe I am not alone here. I therefore look forward to further discussions of Terry's approach to information in which the additional physics and its dynamic logic might be explicitly taken into account.
