Dear all, I make the last remark about "physical information". The main problem of quantum physics is to justify so called IRREDUCIBLE QUANTUM RANDOMNESS (IQR). It was invented by von Neumann. Quantum randomness, in contrast to classical, cannot be reduced to variations in an ensemble. One single electron is irreducibly random.
The operational Copenhagen interpretation cannot "explain" the origin of IQR, since it does not even try to explain anything, "Shut up and calculate!" (R. Feynman to his students). Nevertheless, many top experts in QM want some kind of "explanation". The informational approach to QM is one of such attempts. Roughly speaking, one tries to get IQR from fundamental notion of "physical information" as the basic blocks of Nature. This is very important activity, since nowadays IQR has huge technological value, the quantum random generators are justified through IQR. And this is billion Euro project. Finally, to check experimentally the presence of IQR, we have to appeal to violation of Bell's inequality. And here (!!!) to proceed we have to accept the existence of FREE WILL. Thus finally the cognitive elements appears, but in very surprisingly setting.... Yours, andrei Andrei Khrennikov, Professor of Applied Mathematics, Int.

More on Quantum information and emergent spacetime, this time by Erik P. Verlinde: Emergent Gravity and the Dark Universe<https://arxiv.org/abs/1611.02269> There is a less formal review at http://m.phys.org/news/2016-11-theory-gravity-dark.html I consider the idea very speculative, as I have seen no work on information within a spacetime boundary except for this sort of work. Of course, meaning need not apply. I doubt that it is bounded by language, but it at least has to be representational. Perhaps more is also required. I am reluctant to talk of meaning when discussing the semiotics of biological chemicals, for example, but could not find a better word. A made up word like Deacon’s “entention” might work best, but it still would not apply to the physics cases, even though the information in the boundaries in all cases but the internal information one can tell you about the spacetime structure within the boundary. That seems to me that it is like smoke to fire: smoke doesn’t mean fire, despite the connection.

Dear Alex and colleagues, Thank you for the reference; but my argument was about “meaning”. “Meaning” can only be considered as constructed in language. Other uses of the word are metaphorical. For example, the citation to Maturana. Information, in my opinion, can be defined content-free (a la Shannon, etc.) and then be provided with meaning in (scholarly) discourses. I consider physics as one among other scholarly discourses. Specific about physics is perhaps the universalistic character of the knowledge claims. For example: “Frieden's points apply to quantum physics as well as classical physics.“ So what? This seems to me a debate within physics without much relevance for non-physicists (e.g., economists or linguists).

Dear Loet and Fis Colleagues, Are you aware of Roy Frieden's 'Physics from Fisher Information'. His book was published in the 1990s. I consider it a very powerful statement. Ultimately everything we can detect at both macroscopic and microscopic levels depends on information production from a quantum level that forms Fisher Information. Frieden's points apply to quantum physics as well as classical physics.

However, its use in terms of the living and/or the physical is metaphorical. Instead of a discourse, one can this consider (with Maturana) as a “second-order consensual domain” that functions AS a semantic domain without being one; Maturana (1978, p. 50): “In still other words, if an organism is observed in its operation within a second-order consensual domain, it appears to the observer as if its nervous system interacted with internal representations of the circumstances of its interactions, and as if the changes of state of the organism were determined by the semantic value of these representations. Yet all that takes place in the operation of the nervous system is the structure-determined dynamics of changing relations of relative neuronal activity proper to a closed neuronal network.” Failing to "make that connection" simply leaves one with an explanatory gap. And then, once connected, a further link to "space-time" is also easily located . . . Yes, indeed: limiting the discussion to the metaphors instead of going to the phore (that is, language and codification in language) leaves one with an explanatory gap. Quantum physics, for example, is a highly specialized language in which “mass” and “information” are provided with meanings different from classical physics.
