Dear Pedro and colleagues,
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?
I am not so convinced that there is an a priori relation between life
and communication. Communication is not alive. Non-living systems (e.g.,
computers, robots) also communicate. Perhaps, it matters for the
communication whether the communicators are living systems; but this
needs to be specified.
Communication studies is not biology. Perhaps, there is a specific
biological communication as Maturana claims: when molecules are
exchanged, one can expect life. Can one have life without communication?
It seems to me that one can have communication without life.
Communication would then be the broader category and life a special
case.
Best,
Loet
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
