Howard Pattee defining *internal* #description and #construction as the fundamental requirements for #life and other life related qualities such as (autonomous) #agency, #consciousness ... It is interesting that not even von Neumann's UC would qualify. Excerpts from: www.academia.edu/6576779/Rose...
PATTEE Let me say it another way. Let me begin with a biological
definition, and then try to translate that into the physical terminology.
Living systems consist of a gene which is translated and read out into the
phenotype or the organism. The whole idea of evolution depends on the
distinction between the genotype and phenotype, and I'm willing to
accept this as the basic requirement for life. The question then is: what are
the minimum conditions for a genotype-phenotype system?
Now, in order not to use those same words, I translate them into a
*description-construction system,' and then ask what that means in physi-
cal terms. First of all (I suppose this is a philosophical presupposition), I
look on the world the physicists think about as being primarily involved
with space, time, matter,and energy, and the observables that human
beings choose as connected with dynamical equations that relate these
observables to space and time. In none of these non-living systems do we
find internal descriptions. At least that's not the way we look at physics;
we look at it as autonomous and inexorable motions or processes that go
on according to the laws of nature. We can describe this system and make
measurements on it, but the system can only behave according to the laws
of nature. In living systems, however, we have the process of internal
self-description. They also appear autonomous, but when we describe a
living system, we must include the genetic input, which is, in effect, a
constraint on the laws of motion. Through the genetic code, there are
certain molecules - the DNAS - which exert a very peculiar effect on the91 Robert Rosen, Howard Hunt Pattee, and Raymond L. Somorjai

dynamics of the system, peculiar in the sense of physics. And I believe
that the minimum requirement for this peculiar type of interaction is a
self-describing, self-interpreting system; this is the basis of self-replica-
tion and hence evolution. Now, the particular living systems that we ob-
serve today are regarded by most molecular biologists as the only systems,
or at least the only interesting systems. I think that this is not the most
useful way to look at the nature of life. I think one should ask the ques-
tion: What are the essential properties of such a system? One reason I
suspect that the particular system that now exists is not the most funda-
mental is that all description-construction systems that I know have an
essential arbitrariness about them. Jacques Monod calls this the principle
of gratuity, which is a good way to say it, but I prefer just to call it arbitrari-
ness, in the mathematical sense. We label things in mathematics arbitrar-
ily, which means nothing more than we have a definite symbol; some-
thing is chosen absolutely, but that which is chosen is not really relevant.
Now, the real mystery is how, from an inexorable physical dynamics, one
could ever achieve an arbitrary self-coding, self-describing system. I
would repeat that the essential requirement of life is that it is a self-
describing, self-constructing system.

Howard Pattee has one of the most consequential, comprehensive and well thought approaches in modern evolutionary biology. Unfortunately, many just try to fit bits and pieces of his theories into boxes instead of trying to understand the philosophy behind the science www.academia.edu/127552909/Re...
Umerez is correct that until recently I was unaware of the new field of
biosemiotics. In fact, until I read Kull's (2007a) and Favareau's (2007) histories I had no idea of how the current discipline of biosemiotics originated or how it had been promoted by Sebeok, Hoffmeyer, Barbieri, and others. As judged by its current literature, Umerez is also justified in concluding, "that Pattee is not properly a biosemiotician." I have no problem being an improper biosemiotician as long as I pass as a proper physicist and evolutionary biologist. Jon continues, "His [Pattee's]
perspective has not been and it is not semiotic. His use of linguistic vocabulary: language, code, symbol, etc, is just in plain terms and not as part of a specialized terminology." That is true. The symbol-matter problem that I consider fundamental is primarily a physics problem. I use conventional terminology from the culture of physics, and I do not coin words. In my papers I try to credit the experts who influenced my thinking, and none of them are semioticians.

I doubt von Neumann would agree that DNA sequences are computer code. As he wrote in TSRA, "by axiomatizing automata in this manner, one has thrown half of the problem out of the window, and it may be the more important half." It's the stuff that can't be formalized that's interesting.
