However, physics is not suitable for describing living systems. — Wolfgang
Because life follows other organizational principles than inanimate nature. — Wolfgang
Wolfgang seems to be talking about "self-organization" in a cosmic sense, to raise the question of how living creatures could be assembled out of non-living matter. He attributes that creative & organizing ability to the "four fundamental forces that govern the universe"*1. He didn't itemize those forces, but I assume he's referring to gravity, electromagnetism, and the strong and weak nuclear forces. Those binding & repelling forces certainly have something to do with organization of matter into aggregations, but exactly how lumping & clumping results in the holistic function we call Life remains unclear.If you want to study self-organisation more formally, SO in physics is best approached through dissipative structure theory, as part of thermodynamics. SO as life and mind is best described by biosemiosis. — apokrisis
but exactly how lumping & clumping results in the holistic function we call Life remains unclear. — Gnomon
A different life-force was recently proposed by an MIT physicist*2, but it does just the opposite of aggregating & organizing compulsions. — Gnomon
In my opinion, Pattee makes the mistake of assigning human concepts to nature. — Wolfgang
A functioning organization is something that works according to certain rules, and those rules are made by someone in, say, a social organization. If we assume that there is nothing and no one who has developed rules for life, then it must be life itself that has developed these rules.
In addition to these rules, there must of course be an authority that monitors compliance with the rules and corrects them if necessary. — Wolfgang
Your snarky responses sound like you think Enformationism is contradictory to Biosemiotics or to Biophysics*1. But in my thesis & blog, I have referred to Biosemiosis*2 as an example of a possible information-processing mechanism in living organisms. The primary difference is that BS & BP are hypothetical mechanisms in Biology, while EnFormAction is a hypothetical organizing (enforming) process in Cosmology. So, although both are science-related philosophical theories, they are not competing against each other.Bollocks. Biophysics speaks directly to the issue. — apokrisis
One of my favorite scientists (evolutionary biology + neuroscience), Terrence Deacon, has contributed several novel ideas that I adopted in my own philosophical theories. — Gnomon

You are talking about Physics, while I'm talking about Philosophy --- on a philosophy forum. That may be why we are not communicating. Physical Cosmology and Philosophical Cosmology are two sides of the same coin*1. But apparently you are not seeing my side : the non-physical metaphysical mental half of the universe that is meaningful only to rational philosophical animals, who think about ideas that are not physical things. :smile:Biosemiosis is based on the physics of dissipative structure. And dissipative structure is also the basis of cosmology. — apokrisis

But if you want to understand life 'from the inside', this is not enough. Thermodynamics does not explain that autocatalytic process, nor does it explain the steering and control instance that life implies. — Wolfgang
You'll want to read this to get up to speed on what apokrisis is referring to (but it's also a worthwhile study in its own right. Apokrisis is or was a student of Howard Pattee who is mentioned in the first paragraph.) — Wayfarer
Apparently, something about my information-based worldview is discomfiting for you. Perhaps you feel that it denies a belief system that makes sense of the world for you. Yet, my philosophy encompasses a variety of perspectives. That's why I call it "BothAnd". It's both Realism and Idealism, both Reductionism and Holism, both Materialism and Informationism (which some may interpret as ancient Spiritualism). That doesn't mean all perspectives are true, but that the truth typically lies in the overlapping margins of Venn-diagram oppositions.You tell yourself whatever gives you comfort. But I will continue calling bullshit on your conflationary arguments about "information". — apokrisis
This is the deficiency of systems theory. — Metaphysician Undercover
Apokrisis has directed me to enough material for me to see that Pattee's theory is hugely deficient. — Metaphysician Undercover
Markoš underlined that in human affairs we do observe real change, because our history is ruled by contingency, and entities like literature and poetry show that creativity does exist in the world. He maintained that this creative view of human history can be extended to all living creatures, and argued that this is precisely what Darwin’s revolution was about. It was the introduction of contingency in the history of life, the idea that all living organisms, and not just humans, are subjects, individual agents which act on the world and which take care of themselves. ...According to Markoš, the present version of Darwinism that we call the Modern Synthesis, or Neo-Darwinism, is a substantial manipulation of the original view of Darwin, because it is an attempt to explain the irrationality of history with the rational combination and recombination of chemical entities. Cultural terms like information and meaning have been extended to the whole living world, but have suffered a drastic degradation in the process. Information has become an expression of statistical probability, and meaning has been excluded tout court from science.
The vast flow of perceptions, ideas, and emotions that arise in each human mind is something that, in his view, actually exists (I would say: is real) as something other than merely the electrical firings in the brain that gives rise to them—and exists as surely as a brain, a chair, an atom, or a gamma ray.
In other words, even if it were possible to map out the exact pattern of brain waves that give rise to a person’s momentary complex of awareness, that mapping would only explain the physical correlate of these experiences, but it wouldn’t be them. A person doesn’t experience patterns, and her experiences are as irreducibly real as her brain waves are, and different from them. — Thomas Nagel - Thoughts are Real
I respect Pattee and have learned from him. I'm also cognizant that biosemiotics is a wide-ranging discipline accomodating divergent perspectives (that's why I linked to the Short History article, which is an overview.) — Wayfarer
Yes, he has a deep understanding of the workings of biological organisms, and many clear thoughts. However, his speculative theory of biosemiotics is deficient for the reasons I described. When you study biosemiotics further, in the future, keep in mind the issue I mentioned, and now that it's been pointed out to you, it ought to become evident that it's a very real problem, indicating that biosemiotics is quite insufficient. — Metaphysician Undercover

Apokrisis has directed me to enough material for me to see that Pattee's theory is hugely deficient. Interpretation of signs, or symbols, to decipher meaning, requires an agent which does the interpreting. — Metaphysician Undercover
Try reading again and realising that biosemiosis doesn’t talk about agents who interpret but systems of interpretance. — apokrisis
It is only by denying the reality of the agent, that the system can be presented as top-down causally, rather than the true bottom-up causation, which is indicated when the agent is included. — Metaphysician Undercover
But you are still stuck in the immediate post-medieval stage of theistic thought. Even Kant and Schelling are adventures yet to be undertaken. — apokrisis
This is the deficiency of systems theory. Boundaries are used to distinguish what is part of the system from what is not part of the system. But there are no principles to distinguish a spatially external boundary from a spatial internal boundary, so anything which is not part of the system is generally understood as, "outside the system", or spatially external. A proper understand requires distinguishing between what is not part of the system by being across an internal boundary, from what is not part of the system by being across an external boundary. — Metaphysician Undercover
Closed and Open Systems
Conventional physics deals only with closed systems, i.e. systems which are considered to be isolated from their environment.
However, we find systems which by their very nature and definition are not closed systems. Every living organism is essentially an open system. It maintains itself in a continuous inflow and outflow, a building up and breaking down of components, never being, so long as it is alive, in a state of chemical and thermodynamic equilibrium but maintained in a so-called steady state which is distinct from the latter.
It is only in recent years that an expansion of physics, in order to include open systems, has taken place. This theory has shed light on many obscure phenomena in physics and biology and has also led to important general conclusions of which I will mention only two.
The first is the principle of equifinality. In any closed system, the final state is unequivocally determined by the initial conditions: e.g. the motion in a planetary system where the positions of the planets at a time t are unequivocally determined by their positions at a time t°.
This is not so in open systems. Here, the same final state may be reached from different initial conditions and in different ways. This is what is called equifinality.
Another apparent contrast between inanimate and animate nature is what sometimes was called the violent contradiction between Lord Kelvin's degradation and Darwin's evolution, between the law of dissipation in physics and the law of evolution in biology. According to the second principle of thermodynamics, the general trend of events in physical nature is towards states of maximum disorder and levelling down of differences, with the so-called heat death of the universe as the final outlook, when all energy is degraded into evenly distributed heat of low temperature, and the world process comes to a stop. In contrast, the living world shows, in embryonic development and in evolution, a transition towards higher order, heterogeneity, and organization. But on the basis of the theory of open systems, the apparent contradiction between entropy and evolution disappears. In all irreversible processes, entropy must increase. Therefore, the change of entropy in closed systems is always positive; order is continually destroyed. In open systems, however, we have not only production of entropy due to irreversible processes, but also import of entropy which may well be negative. This is the case in the living organism which imports complex molecules high in free energy. Thus, living systems, maintaining themselves in a steady state, can avoid the increase of entropy, and may even develop towards states of increased order and organization. — Ludwig von Bertalanffy, General system Theory (1968)
