Or to look at it another way, using Shannon, unexpected messages can be transmitted (broadcast) to the receiver (molecular machine) in the form of noise (e.g. RNA as in virus) in the channel. This would be the mechanism for mutation in evolution theory.
However, a really big however, the channel (autonomy) must pre-exist along with the symbols (encoding and decoding of the message.) And we can't get there (iii) from here (ii).
Also, I very strongly agree with you that this irreducible structure argument has great potential and needs further development.
Excellent observation, dearest sister in Christ!
CottShop, you wrote, "the TOE supporter 'might be able to mount a remotely possible argument that a great many mutations at level (ii) kept adding their own contributions of info by altering the level (ii) info to the point where it might possibly accumulate to a point of a bit higher metainfo."
But "who" or what at level (ii) is "adding" or "accumulating" the info? It seems to me a person making this argument would have to attribute some form of "proto-consciousness" to molecules and/or atoms. Information doesn't just "add itself" so to produce metainformation. Or so it seems to me. (There's a stark difference between "data" and "information.") And as far as I know, the articulation of symbols is not possible for an entity lacking consciousness and some minimal threshold of intelligence.
I'd love to see how the person advancing this gradualisitic piling up of "information" and its conversion to metainformation at level (ii) [from whence it is "passed along" to level (iii)], from the resources of (ii) and/or (i) will deal with this objection.
Well, just my two cents worth FWIW.
Thank you A-G and CS so very much for your excellent essay/posts!
