Karl:
I will respond to both your new title to the thread and to your
philosophy of mathematics.
When you ask the question, "what is life, logically?" what is the
nature of the question that you wish to address? Given your history
of posts, I am almost certain that I do not understand what you are
asking.
The principle issue that separates our views is not the nature of
life or information, it is the nature of scientific logic and a
philosophy of mathematics.
The concept of "logic" dates back to pre-Aristotelian days and it is
no clearer today, in my opinion, than when Aristotle defined his
views of causality and categories. (The small book, "Logic, A short
introduction" by Graham Preist, OU Press, is to be recommended.)
Model theory and various sorts of set theory are often promoted by
promoters. Yet, no one has succeeded in applying set theory to
chemical theory and phenomena. The oft stated claim that "quantum
theory" covers all of chemistry lacks supporting evidence. It really
refers to calculating properties of molecules AFTER one is given the
exact enumerations of structural organization in space.
If anyone would like to demonstrate that quantum theory covers
chemistry, the place to start is to show how quantum theory applies
to a simple enzymatic reaction. For example, give an exact
calculation of the transfer of electrons from ethyl alcohol to NAD
via the enzyme alcohol dehydrogenase, starting from physical
principles. Chemists have developed exact methods to give an
accounting of the particles and their positions for this reaction.
The simple fact of the matter is that physical quantum theory is
derived from the chemical table of elements and chemical relations
and not vice versa. The list of chemical elements is an abstraction
about invisible particles with electrical properties and relations
among them. Chemical quantum mechanics simply places the objects in
motion. (Physical quantum mechanics is awash in the mathematical
approximations that attempt to use 1 or 2 or 3 or 4 different
mathematical definitions of force into a logically consistent
framework. Which notion of force should I believe in? Have you a
favorite definition of force? If one makes a sufficient number of
approximations, one can eventually fit empirical data - this is
remote from the exactness of chemical calculations!)
More generally, I believe that the nature of logic itself is
intertwined with the the semiotics of the symbol systems. Logical
methods are not general. We have many classes or types of logic.
These logics are intimately intertwined with the grammar of the
particular symbol system that is being used. The grammar of addition
is hardly the grammar of our emotions, is it? The grammar of music
is hardly the grammar verbal expression. The grammar of chemistry is
highly context dependent. a modal grammar that is closer to Aristotle
than to quantum mechanics and its inability to correspond directly
with human sensory perceptions. Can anyone point out how the axioms
of set theory or group theory express the grammar of genetic systems?
I point I am seeking to make is that the oft expressed notion that
certain logical statements are "true for all time and place" is a
statement that can not be placed directly in correspondence with
empirical observations in the many, many many areas of biology and
medicine.
So, when you ask, "what is the life, logically?", I think you will
get many answers and that these answers are more apt to reflect on
the individual philosophy of mathematics and science and little to do
with the question.
For me, a rough answer that is little more than a tautology is " Life
is a chemical system that co-operates with an ecosis to reproduce
systems similar to itself. "
Enough venting of my views! A few comments are interlaced into to
your response below.

I concur with Stan and add that the problem is the nature of
catalysis, not a particular structure.

Karl: No. The issue is not the validity of your mathematics. As far
as I know, your mathematics is perfectly fine number theory. The
question is, how does your number theory result relate to empirical
genetic observations? What is the path between your interiority,
your thinking, and the exteriority of the natural world, reality if
you will, and genetic systems in general?

Nonsense. it is closer to Russell's notion of an atom of logic.
A chemical atom is defined in terms of the number of particles,
properties of same, and relations.

Chemical computations of valence are based on context dependent
relations.
In general, arithmetic operations (with associative and distributive
laws) of compilers are not used to compute valence.

What is the linkage to genetics? To heredity?
What is the correspondence between "the inner workings of compliers"
and inheritance of biological properties?

This is fine mathematical philosophy for variables and calculations
on variables.
Now, can you show how these calculations can be used to relate
genetic sequences to biological properties?
What is the semantic path between your nouns and verbs and the nouns
and verbs of chemistry and biology and medicine?

Karl, your argument wanders over vast domains. What I am seeking is
a particular path, a particular collation of syllogisms (sorites)
that relate the concepts of number theory to the concepts of
chemistry, biology and medicine. If such a path is stated, then we
can compare the statements to particular observations in the
experimental sciences.
Cheers
jerry
