Can the Monist View Explain What Is Life?
by Alamo-Girl and betty boop
In this article we would like to address the soundness and adequacy of the monist view of reality which conceives of all that there is as ultimately reducible to the concept of matter in its motions. This view holds that there is no essential difference between living and non-living systems in nature since both ultimately are expressions of the workings of the physical laws and only the physical laws. This insight or expectation leads one to presume that the laws of physics and chemistry are entirely sufficient to explain how matter came one day to spontaneously generate Life and thus all evolving living systems. This hypothesis is called abiogenesis and, try as hard as many first-rate researchers have done thus far, the fact is it has never yet been scientifically demonstrated.
Darwin studiously avoided abiogenesis in his major works hence the insistence on the forum that the theory of evolution does not include abiogenesis. Perhaps his avoidance of the issue was for political reasons, we dont know. At any rate, Darwin was known for his speculations about a warm little pond though evidently he didnt want it to be a part of his theory. http://www.evowiki.org/index.php/Abiogenesis.
And yet one readily gets the impression on following the forum debate that many, if not most, subscribers to Darwins theory suppose that abiogenesis did, in fact, occur in some far distant past. On this view, biological evolution takes its origin from an unvalidated event that is presumed to be wholly material in character. This materialist aspect is fully consonant with the Darwinian view; abiogenesis rounds out the cosmological view to include a beginning, the problem that Darwin sought to avoid.
Implicit in the monist theory is the expectation that the universe is causally closed. All causes are material causes, and what we see all around us is the present cumulative effect of a virtually infinite succession of random material events that have taken place from a virtually infinite past until now. Such causes arise only within the 3+1 dimensional block of space-time as we humans normally experience/conceive it.
Yet as Elitzur (1993) points out, the most essential attribute of randomness is the absence of connection between the states of the systems components. Organization, by definition, means that the systems parts are highly correlated. The converse of organization is reducibility or separability. Therefore, organization means non-separability, connectivity. A. Grandpierre points out that biological organization is different from physical ordering that is accompanied by a decrease of entropy. While physical ordering (misleadingly called self-organization, but its actual meaning is self-ordering) plays an important role in storing information, the dynamical process of government through information is a process with a quite different nature.
And yet the monist view holds that all that there is is fundamentally reducible to material random events or accidents being fortuitously tamed or shaped by physical laws. Which is what you would expect if you think that only material, physical, tangible entities are real. And thus information processing in living systems is a subject that can never come up in the first place; for fundamentally it is an immaterial, intangible process.
And yet heres the interesting situation that develops from the physicalist (i.e., monist) concept: The physical laws themselves are immaterial, non-physical, intangible entities. It is here that the monist view breaks down as a valid interpretation of nature on its own terms. You cant at the same time say that physical matter is all that there is and then turn around and invoke an immaterial principle that conditions or determines material behavior without engaging in self-contradiction.
And what can we say about the physical laws themselves the great laws of motion and thermodynamics? Assuming that they tame matter or cause it to behave in certain ways, and assuming that matter is more or less dumb and blind (and quite possibly lazy!), then the physical laws must possess an informative content. And theres another very interesting thing about the physical laws: They are in the main all laws of conservation. It has been observed that the amount of information required for conservation of a system seems not to be high, at least in comparison with the amount of information needed for a system to organize itself, modify its behavior, develop, evolve. For matter, left to its own devices (e.g., blind, dumb, and lazy devices), will follow the principle of least action. To put this into perspective, Paul Davies (The Fifth Miracle, 1998) writes:
The laws of physics are algorithmically very simple; they contain relatively little information. Consequently they cannot on their own be responsible for creating informational macromolecules life cannot be written into the laws of physics . Life works its magic not by bowing to the directionality of chemistry, but by circumventing what is chemically and thermodynamically natural. Of course, organisms must comply with the laws of physics and chemistry, but these laws are only incidental to biology.
For the above reasons, the present writers remain skeptical about claims issuing from the monist position with regard to the fundamental origin and nature of life in the Universe. There is a need to account for, not only the fact that life cannot be exhaustively explained in terms of what is chemically and thermodynamically natural; but even more importantly, that life seems to work to counter the outcomes predicted by the physical laws.
Of particular interest is the possible relation of entropy and information in living systems. By information we mean the successful communication of a message (or informative text) such as to cause a reduction of uncertainty in the receiver, as formulated in terms of Shannon information theory. Note that reduction of uncertainty in the receiver issues as an actual event by virtue of a decision made and thus is analogous to state vector collapse in quantum microsystems, and to realized intended outcomes of sentient beings in real-world macrosystems. In all three cases, it appears that the probability amplitude is collapsed into just one choice, and all other possibilities vanish into a netherworld of unrealized (at that moment at least) potentialities. In all three cases, we seem to be looking at instances of very frank quantizations of the continuum.
Thus the thought occurs to one: Perhaps it is the ubiquitous presence of observers making informed choices which constitutes the irreversible arrow of time of the second law of thermodynamics. For observations lead to events (decisions) which, in the 3+1D block, constitute a successive temporal sequence of newly produced causes or, more to the point, a history (which can be thought of as evolution in retrospect). And history like memory is an irreversible process.
Alternatively, in the Feynman/Everett multi-world models, history may be a sum of histories (the cat is both alive and dead). In the second case the apparent thermodynamic entropy on our particular worldline as observer (the phenomenon which suggests an arrow of time) is only one selection though for our worldline that path or arrow of time would likewise seem irreversible. Whether or not it is actually irreversible and whether the arrow of time itself points in one direction only depends on whether there is another temporal dimension (f-Theory, Vafa). We need to mention that we recognize the significance of other multi-world and extra temporal dimension models as competing cosmological views. A fuller treatment of this subject is beyond the scope of the present article.
Now it is controversial that thermodynamics can have anything at all to do with the propagation and transmission of information. Indeed, it is reasonable to draw the negative conclusion, provided that ones thermodynamical model is the one espoused by Boltzmann, whose hypothesis was that the second law is a law of disorder, of chaos. That hypothesis alone would appear to make thermodynamics a problematical construct for systems that are complex and self-organizing, such as living systems seem to be. And yet living systems are ineluctibly microstates within the global macrostate so well described by the second law of thermodynamics. This problem has been well noted.
Yockey, for instance (in Information Theory and Molecular Biology, 1992), presented a mathematical proof that Shannon entropy and thermodynamic entropy are functions of probability spaces that are not isomorphic. From this mathematical fact, he draws the conclusion that these two entropies have nothing whatever to do with each other:
The function for entropy in both classical statistical mechanics and the von Neumann entropy of quantum statistical mechanics has the dimensions of the Boltzmann constant k and has to do with energy and momentum, not information.
But what if the sine qua non hallmark or signature of living organisms is that they work by converting thermodynamic entropy into Shannon entropy? This would mean that although the two entropies belong to non-isomorphic probability spaces, living organisms preeminently possess a mechanism to bring the two probability spaces into direct relations. Indeed, that may be the entire point about what it is that constitutes the difference between a living and non-living system.
This is the problem that Hungarian astrophysicist A. Grandpierre tackles straight on in a forthcoming work. It is perhaps surprising that an astrophysicist would veer into biology. It turns out that his researches into the nature of the Sun suggested that astral bodies are self-organizing systems that actively work against the setting up of thermodynamic equilibrium that would otherwise obtain given initial and boundary conditions. In other words, the Sun is not a hot ball of gas. And so the resemblance of the Suns observed behavior to anything that we normally perceive as biological behavior struck him as an interesting problem.
As for the criteria of biological behavior to be applied, Grandpierre primarily draws on Ervin Bauer, a Hungarian theoretical biologist and physicist active during the first part of the 20th century, largely under Soviet auspices. Bauer is little known today. (His work, Theoretical Biology [1935], was published only in German and Russian and, we gather, is out of print anyway.) But we think he will make a come-back. For as far as we know, it was Ervin Bauer who first drew thermodynamics into explicit connection with biological theory, and Grandpierre highly values his insights:
Living organisms do not tend towards the physical equilibrium related to their initial and boundary conditions, but [at all times] act in order to preserve their distances from the deathly physical equilibrium predicted by the second law.
This says that, unlike physical systems, living systems move in just the opposite direction from that predicted by the second law: that is, living systems, for as long as possible, are devoted to evading or forestalling the eventual total loss of potential energies for the task of productive work, and thus ultimately heat death. But if living systems can counter the second law, then one must ask, how do they do that?
Grandpierre notes that entropy is a somewhat subtle concept just because it connects two fundamentally different realms, of which only one is usually termed as reality. Entropy connects the realms of possibilities with the world of manifested phenomena. If one would guess that possibilities do not exist since they do not belong to the phenomenal world, this would be conceptually confusing at the proper understanding of physical world. The central role of entropy is one of the most fundamental laws of Nature; the second law of thermodynamics tells that possibilities do belong to reality and determine the direction of development of physical systems.
Realizing the possibilities appears to depend on information. And so,
[First we must] quantify some biologically fundamental aspects of entropy, information, order, and biological organization. Thermodynamic entropy, S and the entropic distance of the human body from its physical equilibrium at constant internal energy [must be] determined quantitatively, together with the number of microstates related to physical, chemical, and biological macrostates.
We distinguish between physically and biologically possible states. In physical objects internal energy is redistributed by dissipative processes. In living organisms the Gibbs free energy, G is also redistributed, but not only in the individual degrees of freedom, but also by means of the consecutively coupling action of biological organization, which works on the whole set of all possible collective degrees of freedom.
From the here determined quantities [that] shed light on the source of biological information .our calculations show that the relatively high value of S [entropy] enhances the ability of living matter to represent information.
And thus, by determining the average information flow of a cell in the human body, and determining the enthalpy of a DNA molecule, we can draw quantitative consequences with regard to the static and dynamic information content of DNA. We estimated that the information necessary to govern the >105 chemical reactions sec1 cell1 in the 6*1013 human cells requires >1019 bits sec1 that cannot be supplied from the static sequential information content of DNA ~109 bits for more than 1010 sec. Physical self-ordering and biological self-organization represent opposite yet complementary tendencies that together cooperate to serve optimal balance. All these results together show that the source of biological information is ultimately to be found in the Bauer principle, in the same manner as the source of physical information is to be found in the [least-]action principle of physics.
Elsewhere Grandpierre refers to the Bauer principle as the life principle. This has been alternatively termed as the fecundity principle (Swenson), or the will to live. It is customary to regard DNA as the information source that drives living systems. But having estimated the gigantic information flow present in the human body, and comparing that with the static information content of DNA, Grandpierre realized that there is something like a 20-orders of magnitude deficit in DNA information as compared with this number. We point out that DNA is the same in every cell of the body; and yet different cells are undergoing all kinds of different reactions, are involving themselves in collective modes (formation of macromolecules, organs, etc.) constantly. Obviously, the relatively low information content of DNA cannot explain the huge variety of functions that are taking place in the human body at every instant of time. Another interesting fact is that an organisms DNA is exactly the same in a living cell as it is in a dead one. Thus if anything, it appears that DNA primarily works at the level of physically-possible systems (which are those that are still operational after death occurs), and so does not appear to be the only or even the main factor in biological self-organization, self-maintenance, etc. In order to be effective in the governance of biologically-possible systems, DNA itself must have access to a dynamic information source in order to compensate for the deficit of its static information in terms of driving biological behaviors.
So, where does this dynamic information come from? We are usually criticized for introducing a pink unicorn at this stage of the argument, for we propose that biological information is carried by a universal field. And yet the existence of fields is uncontroversial in science. We know that there are particle fields, force fields (e.g., EM, gravitation fields), and the reality of vacuum field is also uncontroversial. The main point about a field is its universal extent. Being universal, it is not an ordinary object of 3+1D spacetime. Rather, fields constitute matrices in which events happen, ultimately unifying all world processes into one integrated whole.
Fields apply universally to all points in space/time every where and every when thus they are neither time-restricted nor spatial coordinate restricted.
Grandpierre argues that, in addition to the other fields identified by science, there is also a biofield or an organic zero-point vacuum field that is the carrier of biological information. An analogy might help to explicate the theory. The Internet is a universal information field that can be accessed by anyone who has the proper equipment. There are often cases when communications are sent to us over the Internet. DNA stands for the particular address at which we can be successfully contacted; DNA is smart enough to be a router for incoming information addressed specifically to a particular receiver. And its presence as a router is necessary; otherwise, information being addressed to us would have no efficient way to reach us and, thus, to do us any good.
One might speculate that the physical laws, being also universal in extent and application, may similarly be field-carried phenomena in this sense.
In any case, when we speak of a netherworld of yet-unrealized possibilities occasioned by a re-imagined second law, are we not speaking of potentially real things that have to reside somewhere, because they represent states of potentiality that may become actualized? If this netherworld is of universal extent, then it would need a field to carry it.
In the space of a short article, we can only briefly touch on the arguments advanced by Dr. Grandpierre and his associates. If you have an interest in looking at his research, the Journal of Theoretical Biology may soon publish an article of his (working title: Thermodynamic Entropy and Biological Information) which richly details the merest sketch of certain key points given above, and a wealth of others besides.
FYI ... if you have the time and interest!
Every once in a while somebody decides we know all the physical laws and the physics budget can safely be eliminated. Then somebody notices something that doesn't fit and it's off to the races once more.
So the above statement might be true in 952 AD, in 1750, in 1885, again in 1904, again in 1943, again in 1967, and again in 2112. In the inbetween years there are some loose ends and the statement is not true. It is not true in 2005, everything is up in the air again.

We estimated that the information necessary to govern the >105 chemical reactions sec1 cell1 in the 6*1013 human cells requires >1019 bits sec1 that cannot be supplied from the static sequential information content of DNA ~109 bits for more than 1010 sec."

So sorry! -- bb.
Thanks for the ping. You are indeed a wonder!
Per Bruce Lipton, DNA does not control cell processing, but it has a different function and normally remains dormant.
Glad to hear it, RightWhale! Thanks for writing.
That's very interesting, RW. I guess I'm going to have to buy Lipton's book. He's not alone in suspecting that DNA's role is not that of control, but of facilitation. But for DNA to "remain dormant" under normal conditions seems to be a very striking claim.... When it's not dormant, what is it doing, do you think?
Anyway, I have printed out this epochial piece and will peruse it later while waiting for rehearsal to begin.
For the record, I have no interest in such twaddle.
OK balrog666, noted.
Amazing. Both of you.
I would sincerely appreciate both of your undertaking a brief summary (abstract) of this article to insure I'm correctly following it....and then post them, of course.
How does DNA "tap" into the force field of life? is a question that came to my mind, but I'm not sure I'm imagining in the right direction.
"In him was life, and the life was the light of men..." Any "life" given us is a share in a field of already existing life?
I still suspect that there is a dimension as real as dimension time or dimension space, called the dimension of life force (having variable expressions, will, emotion, mind, for want of better terms); when complexity of the physical (non-living) universe reached a threshold, the dimension of life force had a 'hook' upon which the variable expressions of that dimension could then be mixed into the total expressions occurring in the universe of our perception. [I use the term 'continuum' to denote the mixings of variable expressions of the temporal and spatial, and then the temporal, spatial, life force. A fourth dimension I call 'spirit' (for want of better term) would be the current extent of dimensional manifestations we may perceive. Human beings are the only creatures as yet possessing the other three dimensional characteristics; Angels may have dimesnion spirit integrated into their nature, but they lack something of the 'lesser' dimensions to which they are tied (or we are tied, while alive on this planet). Thopught I'd toss that goop into the mix you've posted, with your permission. Noew, to print out the posted document and read it thoroughly. BTW, thanks for posting this thread!
It seems that one cannot understand the beginnings of life without understanding the end. Thus despite all the electical currents through the primordial ooze (Miller, Urey, et al.), I personally doubt whether we will ever penetrate the mind of God (with apologies to Paul Davies) to this extent.
All in Him that made all....
I am just reading (again) about Kurt Godel and the Uncertainty Principle. It is a proven theorem in mathematics that posits that some truths can be true but unprovable. Also there is no way to identify or predict unprovable truths. I think there may be a conection with some of this reasoning. It seems intuitively true that the Monist view might explain all but it might never be possible to provide a proof.
Ya'll are just awesome!
I'll have to digest this and post later.
I thought I was a grump. You're a gump's grump.
When your time runs short, you hate to waste it.
