Caro Plamen Simeonov e Cari Tutti,
secondo U. Maturana e F. Varela la conoscenza ha fondamenti biologici.
Tutta la conoscenza, anche quella fisica, soprattutto quella quantistica,
ha fondamenti biologici. E viceversa, la biologia ha fondamenti
quantistici. Quel che scrivo qui sinteticamente può sembrare apodittico e
dogmatico, ma nei miei libri questo è analizzato, approfondito e sistemato
in modo organico: beninteso, secondo l'ottica della mia "Nuova economia".
Quindi vi sono elementi fondati per condividere l'accostamento tra
"platonismo, teologia, logica e algebra". Così come, a me pare ben fondato
il rapporto quadrangolare che passa tra: i numeri primi, la funzione d'onda
di Riemann, la meccanica quantistica e la geometria frattale (dei mercati)
(cfr. fra gli altri,  Rizzo R., "Una vita. Il figlio del garzone", Aracne
editrice, Roma, 2015, pp. 305-306.)
Un augurio, ancora, pasquale.

I personally consider metabolism to be at the core of what constitutes ‘life’, 
so the notion of autopoeisis is very attractive to me.  It is also possible 
that the richness of life as we know it depends on having metabolisms 
(activity), genomes (memory), and reproduction combined.  The reductionistic 
approach to singling out one of these three pillars of life as its essence may 
be futile.  However, I want to point out that the most reduced version of 
‘life’ I have seen was proposed by Terry Deacon in the concept he calls 
“autocells”.  Terry has made great contributions to FIS dealing with related 
topics, and I hope he will chime in here to describe his minimalist form of 
life, which is not cellular, does not have any metabolism or genetically 
encoded memory.  Autocells do, however, reproduce.

This is a reply to Plamen’s comment about autopoeisis. In their paper 
Maturana,Uribe and Varela give a working model (computer model) for autopoeisis.
It is very simple, consisting of a subtrate of nodal elements that tend to bond 
when in proximity, and a collection of catalytic nodal elements that promote 
bonding in their vicinity. The result of this dynamics is that carapaces of 
linked nodal elements form around the catalytic elements and these photo-cells 
tend to keep surviving the perturbations built into the system. This model 
shows that cells can arise from a very simple dynmamic geometric/topological 
substrate long before anything as sophisticated as DNA has happened.

They seek a materialist understanding of biology as a system, attempting to 
refer to the genetic system as little as possible.

I have until very recently attempted to evade/avoid mechanistic thinking in 
regard to biology, but, on considering the origin of life generally while 
keeping Howard Pattee's thinking in mind, I have been struck by the notion that 
the origin of life (that is: WITH the genetic system) was the origin of 
mechanism in the universe.  Before that coding system, everything was mass 
action.  I think we still do not understand how this mechanism evolved.

Thank you for your responses, Lou and Stan. I am aware about the details of
the autopoietic model. What I was actually addressing by the transition
from abiotic to biotic structures and the later emergence of RNA and DNA
was  this elusive aspect of “mass action” which Stan mentioned, that in my
opinion must have emerged out of the field of “triggered  (by resonance)
potentialities  which deeper theories than QM are trying to develop (cf.
Josephson and Deutsch mentioned earlier). This enigmatic emergence of
action out of nothing (vacuum or pure potentiality) naturally allows  the
(co-)existence of such  heretic ideas as the immaterial “Holy Spirit” or
Hans Driesch”s vitalism, Jean Sharon’s eternal electron, or “The Matrix of
Matter and Life”at the sub-Planckian scale. How about this possible link to
Platonism, theology, logic and algebra?

All the best,

Plamen

PS. I do not know why my notes appear twice on this list.
