[Fis] some notes

[Pedro C. Marijuan]

Dear All,

Herewith some notes on the exchanges of past weeks (sorry, I was away in 
bureaucratic tasks).

1. Agents & Information. There were very good insights exchanged; 
probably both terms make a fertile marriage. Actually I have been 
writing about "informational entities" or "subjects" as 
receivers/builders of information but taking into account the other 
disciplines around, "agents" look as the most natural companion of 
information. The only thing I don't quite like is that they usually 
appear as abstract, disembodied communicative entities that do not need 
self-producing. Their communication is free from whatever life 
maintenance...

2. Eigenvectors of communication. Taking the motif from Loet, and 
continuing with the above, could we say that the life cycle itself 
establishes the eigenvectors of communication? It is intriguing that 
maintenance, persistence, self-propagation are the essential motives of 
communication for whatever life entities (from bacteria to ourselves). 
With the complexity increase there appear new, more sophisticated 
directions, but the basic ones probably remain intact. What could be 
these essential directions of communication?

3. About logics in the pre-science, Joseph is quite right demanding that 
discussion to accompany principles or basic problems. Actually 
principles, rules, theories, etc. are interconnected or should be by a 
logic (or several logics?) in order to give validity and coherence to 
the different combinations of elements. For instance, in the 
biomolecular realm there is a fascinating interplay of activation and 
inhibition among the participating molecular partners (enzymes and 
proteins) as active elements.  I am not aware that classical ideas from 
Jacob (La Logique du vivant) have been sufficiently continued; it is not 
about Crick's Central Dogma but about the logic of pathways, circuits, 
modules, etc. Probably both Torday and Ji have their own ideas about 
that-- I would be curious to hear from them.

4. I loved Michel's response to Arturo's challenge. I think that the two 
"zeros" I mentioned days ago (the unsolved themes around the cycle and 
around the observer) imply both multidisciplinary thinking and 
philosophical speculation...

Best wishes--Pedro
