Dear Guy,

Please allow me to respond to your invitation to Terry with my two cents.

My triad for supporting the dynamics of life is a bit different. I see the
three essential fundamentals as:

1. Aleatoricism

2. Feedback

3. Memory

Just to briefly elaborate on each:

1. I use aleatoricism to avoid the baggage associated with the term
"chance", which most immediately associate with "blind" chance. The
aleatoric spans the spectrum from unique events to blind chance to
conditional chance to propensities to just short of determinism.

2. More specifically (and in parallel with autopoesis) I focus on
autocatalytic feedback, which exhibits the property of "centripetality".
Centripetality appears on almost no one's list of properties of life,
despite its ubiquity in association with living systems.

3. Memory (and information) likely inhered in stable configurations of
processes (metabolism) well before the advent of molecular encoding. Terry
speaks to this point in Biological Theory 1(2):136-49.

My fundamentals do not include reproduction, because I see reproduction as
corollary to 2 & 3.

I propose a full metaphysics for life predicated on these three
assumptions.


Looking forward to what others see as fundamental.

Peace,
Bob

Josephson and Deutsh are not ‘deeper than QM’. Deutsch for example is a very 
literal interpretation of QM that says that all the trajectories in the Feynman 
path sum are real, and they occur in parallel universes. This is a nice 
mathematical way to think, but it is not deeper than present QM!
Energy is conserved, but ‘particles’ and indeed universes can be created from 
vacuum. If we want to go to discussion of ‘holy spirit’ then one should look at 
the structure of thought itself. For it is at the level of thought that every 
concept has a life behind it. Every idea is real and alive. Platonism asserts 
this directly in the belief in the existence of form and this form is a living 
form that we interact with and we are. How these notions are related to QM 
probably does await the emergence of a deeper QM.

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

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)

Josephson and Deutsch mentioned earlier). This enigmatic emergence of
action out of nothing (vacuum or pure potentiality) naturally allows  the

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.

2016-03-29 Thread Dr. Plamen L. Simeonov
Dear Lou, Pedro and All,



I am going to present a few opportunistic ideas related to what was said
before in this session. Coming back to Pivar’s speculative
mechano-topological model of life excluding genetics I wish to turn your
attention to another author with a similar idea but on a sound mathematical
base, Davide Ambrosi with his resume at
https://www.uni-muenster.de/imperia/md/content/cim/events/cim-mathmod-workshop-2015_abstracts.pdf
:

“Davide Ambrosi:

A role for mechanics in the growth, remodelling and morphogenesis of living
systems  In the XX Century the interactions between mechanics in biology
were much  biased by a bioengineering attitude: people were mainly
interested in  evaluating the state of stress that bones and tissues
undergo in order to  properly design prosthesis and devices. However in the
last decades a new vision is emerging. "Mechano-biology" is changing the
point of view, with respect to "Bio-mechanics", emphasizing the biological
feedback. Cells, tissues and organs do not only deform when loaded: they
reorganize, they duplicate, they actively produce dynamic patterns that
apparently have multiple biological aims.

In this talk I will concentrate on two paradigmatic systems where the
interplay between mechanics and biology is, in my opinion, particularly
challenging: the homeostatic stress as a driver for remodeling of soft
tissue and the tension as a mechanism to transmit information about the
size of organs during morphogenesis. In both cases it seems that mechanics
plays a role which at least accompanies and enforces the biochemical
signaling.”





Some more details about this approach can be found here:

http://rsta.royalsocietypublishing.org/content/367/1902/3335

http://biomechanics.stanford.edu/paper/MFOreport.pdf

In other words, for the core information theorists in FIS, the question is:
is there really only (epi)genetic evolution communication in living
organisms. Stan Salthe and Lou Kauffman already provided some answers. I
begin to believe that the transition from abiotic to biotic structures,
incl. Maturana-Varela.-Uribe’s autopoiesis may, really have some underlying
matrix/”skeleton”/”programme” which has nothing in common with the nature
of DNA, and that DNA and RNA as we know them today

may have emerged as secondary or even tertiary “memory” of something
underlying deeper below the microbiological surface. It is at least worth
thinking in this direction. I do not mean necessarily the role of the
number concept and Platonic origin of the universe, but something probably
much more “physical” or at least staying at the edge between
physical/material and immaterial such as David Deutsch’s constructor theory
(http://constructortheory.org/) and Brian Josephson’s “structural/circular
theory” (http://arxiv.org/ftp/arxiv/papers/1502/1502.02429.pdf;
http://arxiv.org/ftp/arxiv/papers/1506/1506.06774.pdf;
http://arxiv.org/pdf/1108.4860.pdf) searching for the theories underpinning
the foundations of the physical laws (and following Wheeler’s definition
for a “Law without Law”.

Some of you may say that QT and Gravitation Theory are responsible for such
kind of strange effects, but I would rather leave the brackets open,
because the recent discussion about potentialities and actualities in QM
brings up the idea that there are still different ways of looking at those
concepts (although they are strictly defined in their core domains). This
was actually also the lesson from the last special issue on integral
biomathics (2015) dedicated to phenomenology, with the different opinions
of scientists and philosophers on obviously clear matters in their domains.
This is why also the question of what we define as science needs to be
probably revised in future to include also such issues that are “felt”
rather than “reasoned”, even if we do not have the “proofs” yet, because
the proofs also emerge as subjective (or perhaps “suggested”! – ask the
psychologists for that aspect) thoughts in the minds of the mathematicians.
I am really glad that we began such a phenomenological discussion on this
aspect such as Hipolito’s paper (
http://www.sciencedirect.com/science/article/pii/S0079610715000899) that
was widely commented in the reviewer’s circle. In many cases when we have a
“fuzzy” intuition about a certain relationship or analogy we miss the
correct definitions and concepts, and so in a creative act to hold down the
flying thought we move to using examples, metaphors, pictures. Pedro
correctly addressed the explanatory problem of science which presupposes a
certain causative and predicative “workflow” to derive a conclusion from
the facts, and this is the way in which also proofs are (selectively) made.
As a young scholar I often wondered how artificially people like Gauss,
Cauchy and
