DEBATE THREAD

This INFORMAL debate will focus on Part 1 and 2 of Alex Williams' paper "Life's irreducible structure." Williams' paper will serve as the affirmative, namely:

(A) All aspects of life (not just bacterial flagellums and blood clotting cascades) lie beyond the reach of naturalistic explanations, and (B) only intelligent design meets the criterion of an acceptable historical inference according to the Law of Cause and Effect.

Part 1 of Alex Williams' paper follows. A link to Part 2 can be found in reply #1. It is strongly suggested that both papers be read before participating in the discussion/debate.

One final note: please refrain from making rude comments, please try to ignore those who do, and please try to stay on topic. All the best--GGG

Life’s irreducible structure—Part 1: autopoiesis

by Alex Williams

The commonly cited case for intelligent design appeals to: (a) the irreducible complexity of (b) some aspects of life. But complex arguments invite complex refutations (valid or otherwise), and the claim that only some aspects of life are irreducibly complex implies that others are not, and so the average person remains unconvinced. Here I use another principle—autopoiesis (self-making)—to show that all aspects of life lie beyond the reach of naturalistic explanations. Autopoiesis provides a compelling case for intelligent design in three stages: (i) autopoiesis is universal in all living things, which makes it a pre-requisite for life, not an end product of natural selection; (ii) the inversely-causal, information-driven, structured hierarchy of autopoiesis is not reducible to the laws of physics and chemistry; and (iii) there is an unbridgeable abyss between the dirty, mass-action chemistry of the natural environmental and the perfectly-pure, single-molecule precision of biochemistry. Naturalistic objections to these propositions are considered in Part II of this article.

Snowflake photos by Kenneth G. Libbrecht.

Figure 1. Reducible structure. Snowflakes (left) occur in hexagonal shapes because water crystallizes into ice in a hexagonal pattern (right). Snowflake structure can therefore be reduced to (explained in terms of) ice crystal structure. Crystal formation is spontaneous in a cooling environment. The energetic vapour molecules are locked into solid bonds with the release of heat to the environment, thus increasing overall entropy in accord with the second law of thermodynamics.

The commonly cited case for intelligent design (ID) goes as follows: ‘some biological systems are so complex that they can only function when all of their components are present, so that the system could not have evolved from a simpler assemblage that did not contain the full machinery.’1 This definition is what biochemist Michael Behe called irreducible complexity in his popular book Darwin’s Black Box2 where he pointed to examples such as the blood-clotting cascade and the proton-driven molecular motor in the bacterial flagellum. However, because Behe appealed to complexity, many equally complex rebuttals have been put forward,3 and because he claimed that only some of the aspects of life were irreducibly complex, he thereby implied that the majority of living structure was open to naturalistic explanation. As a result of these two factors, the concept of intelligent design remains controversial and unproven in popular understanding.

In this article, I shall argue that all aspects of life point to intelligent design, based on what European polymath Professor Michael Polanyi FRS, in his 1968 article in Science called ‘Life’s Irreducible Structure.’4 Polanyi argued that living organisms have a machine-like structure that cannot be explained by (or reduced to) the physics and chemistry of the molecules of which they consist. This concept is simpler, and broader in its application, than Behe’s concept of irreducible complexity, and it applies to all of life, not just to some of it.

The nature and origin of biological design

Biologists universally admire the wonder of the beautiful ‘designs’ evident in living organisms, and they often recoil in revulsion at the horrible ‘designs’ exhibited by parasites and predators in ensuring the survival of themselves and their species. But to a Darwinist, these are only ‘apparent designs’—the end result of millions of years of tinkering by mutation and fine tuning by natural selection. They do not point to a cosmic Designer, only to a long and ‘blind’ process of survival of the fittest.5 For a Darwinist, the same must also apply to the origin of life—it must be an emergent property of matter. An emergent property of a system is some special arrangement that is not usually observed, but may arise through natural causes under the right environmental conditions. For example, the vortex of a tornado is an emergent property of atmospheric movements and temperature gradients. Accordingly, evolutionists seek endlessly for those special environmental conditions that may have launched the first round of carbon-based macromolecules6 on their long journey towards life. Should they ever find those unique environmental conditions, they would then be able to explain life in terms of physics and chemistry. That is, life could then be reduced to the known laws of physics, chemistry and environmental conditions.

However, Polanyi argued that the form and function of the various parts of living organisms cannot be reduced to (or explained in terms of) the laws of physics and chemistry, and so life exhibits irreducible structure. He did not speculate on the origin of life, arguing only that scientists should be willing to recognize the impossible when they see it:

‘The recognition of certain basic impossibilities has laid the foundations of some major principles of physics and chemistry; similarly, recognition of the impossibility of understanding living things in terms of physics and chemistry, far from setting limits to our understanding of life, will guide it in the right direction.’7

Reducible and irreducible structures

To understand Polanyi’s concept of irreducible structure, we must first look at reducible structure. The snowflakes in figure 1 illustrate reducible structure.

Meteorologists have recognized about eighty different basic snowflake shapes, and subtle variations on these themes add to the mix to produce a virtually infinite variety of actual shapes. Yet they all arise from just one kind of molecule—water. How is this possible?

 

Figure 2. Irreducible structure. The silver coins (left) have properties of flatness, roundness and impressions on faces and rims, that cannot be explained in terms of the crystalline state of silver (close packed cubes) or its natural occurrence as native silver (right).

When water freezes, its crystals take the form of a hexagonal prism. Crystals then grow by joining prism to prism. The elaborate branching patterns of snowflakes arise from the statistical fact that a molecule of water vapour in the air is most likely to join up to its nearest surface. Any protruding bump will thus tend to grow more quickly than the surrounding crystal area because it will be the nearest surface to the most vapour molecules.8 There are six ‘bumps’ (corners) on a hexagonal prism, so growth will occur most rapidly from these, producing the observed six-armed pattern.

Snowflakes have a reducible structure because you can produce them with a little bit of vapour or with a lot. They can be large or small. Any one water molecule is as good as any other water molecule in forming them. Nothing goes wrong if you add or subtract one or more water molecules from them. You can build them up one step at a time, using any and every available water molecule. The patterns can thus all be explained by (reduced to) the physics and chemistry of water and the atmospheric conditions.

 

Figure 3. Common irreducibly structured machine components: lever (A), cogwheel (B) and coiled spring (C). All are made of metal, but their detailed structure and function cannot be reduced to (explained by) the properties of the metal they are made of.

To now understand irreducible structure, consider a silver coin.

Silver is found naturally in copper, lead, zinc, nickel and gold ores—and rarely, in an almost pure form called ‘native silver’. Figure 2 shows the back and front of two vintage silver coins, together with a nugget of the rare native form of silver. The crystal structure of solid silver consists of closely packed cubes. The main body of the native silver nugget has the familiar lustre of the pure metal, and it has taken on a shape that reflects the available space when it was precipitated from groundwater solution. The black encrustations are very fine crystals of silver that continued to grow when the rate of deposition diminished after the main load of silver had been deposited out of solution.

Unlike the case of the beautifully structured snowflakes, there is no natural process here that could turn the closely packed cubes of solid silver into round, flat discs with images of men, animals and writing on them. Adding more or less silver cannot produce the roundness, flatness and image-bearing properties of the coins, and looking for special environmental conditions would be futile because we recognize that the patterns are man-made. The coin structure is therefore irreducible to the physics and chemistry of silver, and was clearly imposed upon the silver by some intelligent external agent (in this case, humans).

Whatever the explanation, however, the irreducibility of the coin structure to the properties of its component silver constitutes what I shall call a ‘Polanyi impossibility’. That is, Polanyi identified this kind of irreducibility as a naturalistic impossibility, and argued that it should be recognized as such by the scientific community, so I am simply attaching his name to the principle.

Polanyi pointed to the machine-like structures that exist in living organisms. Figure 3 gives three examples of common machine components: a lever, a cogwheel and a coiled spring. Just as the structure and function of these common machine components cannot be explained in terms of the metal they are made of, so the structure and function of the parallel components in life cannot be reduced to the properties of the carbon, hydrogen, oxygen, nitrogen, phosphorus, sulphur and trace elements that they are made of. There are endless examples of such irreducible structures in living systems, but they all work under a unifying principle called ‘autopoiesis’.

Autopoiesis defined

Autopoiesis literally means ‘self-making’ (from the Greek auto for self, and the verb poiéō meaning ‘I make’ or ‘I do’) and it refers to the unique ability of a living organism to continually repair and maintain itself—ultimately to the point of reproducing itself—using energy and raw materials from its environment. In contrast, an allopoietic system (from the Greek allo for other) such as a car factory, uses energy and raw materials to produce an organized structure (a car) which is something other than itself (a factory).9

Autopoiesis is a unique and amazing property of life—there is nothing else like it in the known universe. It is made up of a hierarchy of irreducibly structured levels. These include: (i) components with perfectly pure composition, (ii) components with highly specific structure, (iii) components that are functionally integrated, (iv) comprehensively regulated information-driven processes, and (v) inversely-causal meta-informational strategies for individual and species survival (these terms will be explained shortly). Each level is built upon, but cannot be explained in terms of, the level below it. And between the base level (perfectly pure composition) and the natural environment, there is an unbridgeable abyss. The enormously complex details are still beyond our current knowledge and understanding, but I will illustrate the main points using an analogy with a vacuum cleaner.

A vacuum cleaner analogy

My mother was excited when my father bought our first electric vacuum cleaner in 1953. It consisted of a motor and housing, exhaust fan, dust bag, and a flexible hose with various end pieces. Our current machine uses a cyclone filter and follows me around on two wheels rather than on sliders as did my mother’s original one. My next version might be the small robotic machine that runs around the room all by itself until its battery runs out. If I could afford it, perhaps I might buy the more expensive version that automatically senses battery run-down and returns to its induction housing for battery recharge.

Notice the hierarchy of control systems here. The original machine required an operator and some physical effort to pull the machine in the required direction. The transition to two wheels allows the machine to trail behind the operator with little effort, and the cyclone filter eliminates the messy dust bag. The next transition to on-board robotic control requires no effort at all by the operator, except to initiate the action to begin with and to take the machine back to the power source for recharge when it has run down. And the next transition to automatic sensing of power run-down and return-to-base control mechanism requires no effort at all by the operator once the initial program is set up to tell the machine when to do its work.

If we now continue this analogy to reach the living condition of autopoiesis, the next step would be to install an on-board power generation system that could use various organic, chemical or light sources from the environment as raw material. Next, install a sensory and information processing system that could determine the state of both the external and internal environments (the dirtiness of the floor and the condition of the vacuum cleaner) and make decisions about where to expend effort and how to avoid hazards, but within the operating range of the available resources. Then, finally, the pièce de résistance, to install a meta-information (information about information) facility with the ability to automatically maintain and repair the life system, including the almost miraculous ability to reproduce itself—autopoiesis.

Notice that each level of structure within the autopoietic hierarchy depends upon the level below it, but it cannot be explained in terms of that lower level. For example, the transition from out-sourced to on-board power generation depends upon their being an electric motor to run. An electric vacuum cleaner could sit in the cupboard forever without being able to rid itself of its dependence upon an outside source of power—it must be imposed from the level above, for it cannot come from the level below. Likewise, autopoiesis is useless if there is no vacuum cleaner to repair, maintain and reproduce. A vacuum cleaner without autopoietic capability could sit in the cupboard forever without ever attaining to the autopoietic stage—it must be imposed from the level above, as it cannot come from the level below.

The autopoietic hierarchy is therefore structured in such a way that any kind of naturalistic transition from one level to a higher level would constitute a Polanyi impossibility. That is, the structure at level i is dependent upon the structure at level i-1 but cannot be explained by the structure at that level. So the structure at level i must have been imposed from level i or above.

The naturalistic abyss

Most origin-of-life researchers agree (at least in the more revealing parts of their writings)10 that there is no naturalistic experimental evidence directly demonstrating a pathway from non-life to life. They continue their research, however, believing that it is just a matter of time before we discover that pathway. But by using the vacuum cleaner analogy, we can give a solid demonstration that the problem is a Polanyi impossibility right at the foundation—life is separated from non-life by an unbridgeable abyss.

Dirty, mass-action environmental chemistry

The ‘simple’ structure of the early vacuum cleaner is not simple at all. It is made of high-purity materials (aluminium, plastic, fabric, copper wire, steel plates etc) that are specifically structured for the job in hand and functionally integrated to achieve the designed task of sucking up dirt from the floor. Surprisingly, the dirt that it sucks up contains largely the same materials that the vacuum cleaner itself is made of—aluminium, iron and copper in the mineral grains of dirt, fabric fibres in the dust, and organic compounds in the varied debris of everyday home life. However, it is the difference in form and function of these otherwise similar materials that distinguishes the vacuum cleaner from the dirt on the floor. In the same way, it is the amazing form and function of life in a cell that separates it from the non-life in its environment.

Naturalistic chemistry is invariably ‘dirty chemistry’ while life uses only ‘perfectly-pure chemistry’. I have chosen the word ‘dirty chemistry’ not in order to denigrate origin-of-life research, but because it is the term used by Nobel Prize winner Professor Christian de Duve, a leading atheist researcher in this field.11 Raw materials in the environment, such as air, water and soil, are invariably mixtures of many different chemicals. In ‘dirty chemistry’ experiments, contaminants are always present and cause annoying side reactions that spoil the hoped-for outcomes. As a result, researchers often tend to fudge the outcome by using artificially purified reagents. But even when given pure reagents to start with, naturalistic experiments typically produce what a recent evolutionist reviewer variously called ‘muck’, ‘goo’ and ‘gunk’12—which is actually toxic sludge. Even our best industrial chemical processes can only produce reagent purities in the order of 99.99%. To produce 100% purity in the laboratory requires very highly specialized equipment that can sort out single molecules from one another.

Another crucial difference between environmental chemistry and life is that chemical reactions in a test tube follow the Law of Mass Action.13 Large numbers of molecules are involved, and the rate of a reaction, together with its final outcome, can be predicted by assuming that each molecule behaves independently and each of the reactants has the same probability of interacting. In contrast, cells metabolize their reactants with single-molecule precision, and they control the rate and outcome of reactions, using enzymes and nano-scale-structured pathways, so that the result of a biochemical reaction can be totally different to that predicted by the Law of Mass Action.

The autopoietic hierarchy

Perfectly-pure, single-molecule-specific bio-chemistry

The vacuum cleaner analogy breaks down before we get anywhere near life because the chemical composition of its components is nowhere near pure enough for life. The materials suitable for use in a vacuum cleaner can tolerate several percent of impurities and still produce adequate performance, but nothing less than 100% purity will work in the molecular machinery of the cell.

One of the most famous examples is homochirality. Many carbon-based molecules have a property called ‘chirality’—they can exist in two forms that are mirror images of each other (like our left and right hands) called ‘enantiomers’. Living organisms generally use only one of these enantiomers (e.g. left-handed amino acids and right-handed sugars). In contrast, naturalistic experiments that produce amino acids and sugars always produce an approximately 50:50 mixture (called a ‘racemic’ mixture) of the left-and right-handed forms. The horrors of the thalidomide drug disaster resulted from this problem of chirality. The homochiral form of one kind had therapeutic benefits for pregnant women, but the other form caused shocking fetal abnormalities.

The property of life that allows it to create such perfectly pure chemical components is its ability to manipulate single molecules one at a time. The assembly of proteins in ribosomes illustrates this single-molecule precision. The recipe for the protein structure is coded onto the DNA molecule. This is transcribed onto a messenger-RNA molecule which then takes it to a ribosome where a procession of transfer-RNA molecules each bring a single molecule of the next required amino acid for the ribosome to add on to the growing chain. The protein is built up one molecule at a time, and so the composition can be monitored and corrected if even a single error is made.

Specially structured molecules

Life contains such a vast new world of molecular amazement that no one has yet plumbed the depths of it. We cannot hope to cover even a fraction of its wonders in a short article, so I will choose just one example. Proteins consist of long chains of amino acids linked together. There are 20 amino acids coded for in DNA, and proteins commonly contain hundreds or even thousands of amino acids. Cyclin B is an averaged-size protein, with 433 amino acids. It belongs to the ‘hedgehog’ group of signalling pathways which are essential for development in all metazoans. Now there are 20433 (20 multiplied by itself 433 times) = 10563 (10 multiplied by itself 563 times) possible proteins that could be made from an arbitrary arrangement of 20 different kinds of amino acids in a chain of 433 units. The human body—the most complex known organism—contains somewhere between 105 (= 100,000) and 106 (=1,000,000) different proteins. So the probability (p) that an average-sized biologically useful protein could arise by a chance combination of 20 different amino acids is about p = 106 /10563 = 1/10557 . And this assumes that only L-amino acids are being used—i.e. perfect enantiomer purity.14

For comparison, the chance of winning the lottery is about 1/106 per trial, and the chance of finding a needle in a haystack is about 1/1011 per trial. Even the whole universe only contains about 1080 atoms, so there are not even enough atoms to ensure the chance assembly of even a single average-sized biologically useful molecule. Out of all possible proteins, those we see in life are very highly specialized—they can do things that are naturally not possible. For example, some enzymes can do in one second what natural processes would take a billion years to do.15 Just like the needle in the haystack. Out of all the infinite possible arrangements of iron alloy (steel) particles, only those with a long narrow shape, pointed at one end and with an eye-loop at the other end, will function as a needle. This structure does not arise from the properties of steel, but is imposed from outside.

Water, water, everywhere

There is an amazing paradox at the heart of biology. Water is essential to life,16 but also toxic—it splits up polymers by a process called hydrolysis, and that is why we use it to wash with. Hydrolysis is a constant hazard to origin-of-life experiments, but it is never a problem in cells, even though cells are mostly water (typically 60–90%). In fact, special enzymes called hydrolases are required in order to get hydrolysis to occur at all in a cell.17 Why the difference? Water in a test tube is free and active, but water in cells is highly structured, via a process called ‘hydrogen bonding’, and this water-structure is comprehensively integrated with both the structure and function of all the cell’s macromolecules:

‘The hydrogen-bonding properties of water are crucial to [its] versatility, as they allow water to execute an intricate three-dimensional “ballet”, exchanging partners while retaining complex order and enduring effects. Water can generate small active clusters and macroscopic assemblies, which can both transmit and receive information on different scales.’18

Water should actually be first on the list of molecules that need to be specially configured for life to function. Both the vast variety of specially structured macromolecules and their complementary hydrogen-bonded water structures are required at the same time. No origin-of-life experiment has ever addressed this problem.

Functionally integrated molecular machines

Figure 4. ATP synthase, a proton-powered molecular motor. Protons (+) from inside the cell (below) move through the stator mechanism embedded in the cell membrane and turn the rotor (top part) which adds inorganic phosphate (iP) to ADP to convert it to the high-energy state ATP.

It is not enough to have specifically structured, ultra-pure molecules, they must also be integrated together into useful machinery. A can of stewed fruit is fully of chemically pure and biologically useful molecules but it will never produce a living organism19 because the molecules have been disorganized in the cooking process. Cells contain an enormous array of useful molecular machinery. The average machine in a yeast cell contains 5 component proteins,20 and the most complex—the spliceosome, that orchestrates the reading of separated sections of genes—consists of about 300 proteins and several nucleic acids.21

One of the more spectacular machines is the tiny proton-powered motor that produces the universal energy molecule ATP (adenosine tri-phosphate) illustrated in Figure 4. When the motor spins one way, it takes energy from digested food and converts it into the high-energy ATP, and when the motor spins the other way, it breaks down the ATP in such a way that its energy is available for use by other metabolic processes.22

Comprehensively regulated, information-driven metabolic functions

It is still not enough to have spectacular molecular machinery—the various machines must be linked up into metabolic pathways and cycles that work towards an overall purpose. What purpose? This question is potentially far deeper than science can take us, but science certainly can ascertain that the immediate practical purpose of the amazing array of life structures is the survival of the individual and perpetuation of its species.23 Although we are still unravelling the way cells work, a good idea of the multiplicity of metabolic pathways and cycles can be found in the BioCyc collection. The majority of organisms so far examined, from microbes to humans, have between 1,000 and 10,000 different metabolic pathways.24 Nothing ever happens on its own in a cell—something else always causes it, links with it or benefits or is affected by it. And all of these links are multi-step processes.

All of these links are also ‘choreographed’ by information—a phenomenon that never occurs in the natural environment. At the bottom of the information hierarchy is the storage molecule—DNA. The double-helix of DNA is ‘just right’ for genetic information storage, and this ‘just right’ structure is beautifully matched by the elegance and efficiency of the code in which the cell’s information is written there.25 But it is not enough even to have an elegant ‘just right’ information storage system—it must also contain information. And not just biologically relevant information, but brilliantly inventive strategies and tactics to guide living things through the extraordinary challenges they face in their seemingly miraculous achievements of metabolism and reproduction. Yet even ingenious strategies and tactics are not enough. Choreography requires an intricate and harmonious regulation of every aspect of life to make sure that the right things happen at the right time, and in the right sequence, otherwise chaos and death soon follow.

Recent discoveries show that biochemical molecules are constantly moving, and much of their amazing achievements are the result of choreographing all this constant and complex movement to accomplish things that static molecules could never achieve. Yet there is no spacious ‘dance floor’ on which to choreograph the intense and lightning-fast (up to a million events per second for a single reaction26) activity of metabolism. A cell is more like a crowded dressing room than a dance floor, and in a show with a cast of millions!

Inversely causal meta-information

The Law of Cause and Effect is one of the most fundamental in all of science. Every scientific experiment is based upon the assumption that the end result of the experiment will be caused by something that happens during the experiment. If the experimenter is clever enough, then he/she might be able to identify that cause and describe how it produced that particular result or effect.

Causality always happens in a very specific order—the cause always comes before the effect.27 That is, event A must always precede event B if A is to be considered as a possible cause of B. If we happened to observe that A occurred after B, then this would rule out A as a possible cause of B.

In living systems however, we see the universal occurrence of inverse causality. That is, an event A is the cause of event B, but A exists or occurs after B. It is easier to understand the biological situation if we refer to examples from human affairs. In economics, for example, it occurs when behaviour now, such as an investment decision, is influenced by some future event, such as an anticipated profit or loss. In psychology, a condition that exists now, such as anxiety or paranoia, may be caused by some anticipated future event, such as harm to one’s person. In the field of occupational health and safety, workplace and environmental hazards can exert direct toxic effects upon workers (normal causality), but the anticipation or fear of potential future harm can also have an independently toxic effect (inverse causality).

Darwinian philosopher of science Michael Ruse recently noted that inverse causality is a universal feature of life,28 and his example was that stegosaur plates begin forming in the embryo but only have a function in the adult—supposedly for temperature control. However most biologists avoid admitting such things because it suggests that life might have purpose (a future goal), and this is strictly forbidden to materialists.

The most important example of inverse causality in living organisms is, of course, autopoiesis. We still do not fully understand it, but we do understand the most important aspects. Fundamentally, it is meta-information—it is information about information. It is the information that you need to have in order to keep the information you want to have to stay alive, and to ensure the survival of your descendants and the perpetuation of your species.

This last statement is the crux of this whole paper, so to illustrate its validity lets go back to the vacuum cleaner analogy. Let’s imagine that one lineage of vacuum cleaners managed to reach the robotic, energy-independent stage, but lacked autopoiesis, while a second makes it all the way to autopoiesis. What is the difference between these vacuum cleaners? Both will function very well for a time. But as the Second Law of Thermodynamics begins to take its toll, components will begin to wear out, vibrations will loosen connections, dust will gather and short circuit the electronics, blockages in the suction passage will reduce cleaning efficiency, wheel axles will go rusty and make movement difficult, and so on. The former will eventually die and leave no descendants. The latter will repair itself, keep its components running smoothly and reproduce itself to ensure the perpetuation of its species.

But what happens if the environment changes and endangers the often-delicate metabolic cycles that real organisms depend upon? Differential reproduction is the solution. Evolutionists from Darwin to Dawkins have taken this amazing ability for granted, but it cannot be overlooked. There are elaborate systems in place—for example, the diploid to haploid transition in meiosis, the often extraordinary embellishments and rituals of sexual encounters, the huge number of permutations and combinations provided for in recombination mechanisms—to provide offspring with variations from their parents that might prove of survival value. To complement these potentially dangerous deviations from the tried-and-true there are also firm conservation measures in place to protect the essential processes of life (e.g. the ability to read the DNA code and to translate it into metabolic action). None of this should ever be taken for granted.

In summary, autopoiesis is the information—and associated abilities—that you need to have (repair, maintenance and differential reproduction) in order to keep the information that you want to have (e.g. vacuum cleaner functionality) alive and in good condition to ensure both your survival and that of your descendants. In a parallel way, my humanity is what I personally value, so my autopoietic capability is the repair, maintenance and differential reproductive capacity that I have to maintain my humanity and to share it with my descendants. The egg and sperm that produced me knew nothing of this, but the information was encoded there and only reached fruition six decades later as I sit here writing this—the inverse causality of autopoiesis.

Summary

There are three lines of reasoning pointing to the conclusion that autopoiesis provides a compelling case for the intelligent design of life.

• If life began in some stepwise manner from a non-autopoietic beginning, then autopoiesis will be the end product of some long and blind process of accidents and natural selection. Such a result would mean that autopoiesis is not essential to life, so some organisms should exist that never attained it, and some organisms should have lost it by natural selection because they do not need it. However, autopoiesis is universal in all forms of life, so it must be essential. The argument from the Second Law of Thermodynamics as applied to the vacuum cleaner analogy also points to the same conclusion. Both arguments demonstrate that autopoiesis is required at the beginning for life to even exist and perpetuate itself, and could not have turned up at the end of some long naturalistic process. This conclusion is consistent with the experimental finding that origin-of-life projects which begin without autopoiesis as a pre-requisite have proved universally futile in achieving even the first step towards life.

• Each level of the autopoietic hierarchy is dependent upon the one below it, but is causally separated from it by a Polanyi impossibility. Autopoiesis therefore cannot be reduced to any sequence of naturalistic causes.

• There is an unbridgeable abyss below the autopoietic hierarchy, between the dirty, mass-action chemistry of the natural environment and the perfect purity, the single-molecule precision, the structural specificity, and the inversely causal integration, regulation, repair, maintenance and differential reproduction of life.

I weouldn’t know- All I know is that the science is for intelligent design, and against common descent as demonstrated many times here on FR.

The science is for ID? LOL Can you point to a single scintilla of evidence that supports ID? ID is not even a hypothesis it is merely the pointing out that TOE does not explain origin of life questions.

The science is against common descent? That is even more funny. We are all eukaryotes, we may all have descended from a single eukaryote. If you are looking for Adam and Eve, the eukaryote agrees better with the story of Genesis. Cell division is akin to taking the ribs out and of Adam and making another copy.

[LeGrande]

I’d can understand people’s confusions with your mighty words. Maybe you should provide diagrams.

Could you tell me what educational level my target audience is? That would be more helpful : )

[LeGrande]

LG - M=F/A So you are saying that if something is at rest it has zero mass too?

Jimmy - No, I am not saying anything of the sort. Those are your ideas. M=F/A, if A=0, M is undefined. Basic algebra dictates that there can not be a zero in the denominator.

I think you should be directing your comments to Metmom she is the one who is trying to divide by zero. Unless of course you are disagreeing with the equation F=MA then you can take that up with Newton. I will attempt to defend Newtons honor to the best of my ability though : )

[bvw]

Well you seem to be targeting yourself. I still don't think you are reaching your audience, even then. What educational level do you think they are?

I mean what educational level talks about force and mass and energy and at the same time doesn't seem to realize that the units are different. And what educational level mashes up division and multiplication as if division is multiplication?

I've checked the in-school detention, and the special needs rooms, I'll wander over to a poetry class. A bad poetry class. Maybe there they throw words around in whatever way they chose.

That is my point. Mass is energy. Yes, we measure mass differently than we measure energy, but they are equivalent. Do you disagree with that?

And what educational level mashes up division and multiplication as if division is multiplication?

That is just my EEE background. All computer functions are addition operations. Subtraction, division, integrals, spread sheets, HTML pages, etc are just addition functions. I learned that in grade school too, I just didn't realize what I had learned until later.

[ I would still like scientists to offer some concrete evidence that life can not only arise spontaneously, but that the amount of change that they claim must have happened to account for the complexity and variety of life we see today is even feasible.

Proposing a theory, not offering any mechanism to disprove it, demanding that it be accepted unless disproved, then blowing off any attempt to do so as *religious and not scientific*, is intellectually dishonest. To determine a priori that any argument against the ToE is religious instead of scientific is as well.

Just because the ToE the only and best explanation that *science* has for a naturalistic, no-God explanation of life on earth, doesn’t mean that it’s right, or even a good one. It’s merely all they have and we don’t have to accept it as correct because there’s no better one in the wings. That’s doing the very thing that creationists are condemned for. ]

This logic is in-escapable.. and pure..
Should be recounted with Barry Whites voice..

Mass is mass. Energy is energy. No, they are not equivalent.

Yes, mass may be converted to energy, but the conversion involves at least a constant that has physical units, not a unit-less constant. And moreover the conversion of mass to energy takes an event. The difference between mass and energy in a system is very hard, very established, and they have different physical units. You did learn something called "unit analysis" is class, did you not?

On examples and test problems "units have to cancel out" and all that?

Mass is not force, mass is not energy, force is not energy. There are formulas for converting mass to force -- that involves acceleration. There are formulas for converting mass to energy. They involve the square of velocity.

Physicists do speak of E = M-zed -- the M in that equation is not mass, it's energy. Rest energy. Sometimes they call it rest mass -- but they don't mean mass, they really mean energy. It's a convenience of expression.

But a physics teacher throwing out a mix of nonsense such as you have would have all his students confused and failing.

Division by zero: In the real world division by zero is not indefinite. We use something in maths called limit theory to get the result.

The lessons of Dover are two:

(1) Local School Boards are not a good vehicle for a long legal fight, because the electoral turnover is too quick -- as quick as a whim.

(2) Judges make science. In today's culture science is dicta. That is what you wanted, right?

The lesson of Dover (short version):

A local school board stocked with creationists sought to have their particular narrow brand of religion taught as science. They got caught. It cost the school district over a million dollars. The school board got turned out of office.

How does one disprove ID?

Yeah, you’re right. better to have the schools indoctrinate a captive audience into Secular Humanism. That’s a much better religion. / sarc

You should step out of your science box. You might think everything in existence is inside the box, but it’s not.

I think it's pretty easy to argue that the Designer isn't human and doesn't design like humans.

For one thing, the Designer went to a great deal of trouble to make living things look like they are related by common descent, right down to non-coding DNA and inherited scars from retrovirus infections. The Designer also also took great pains to make genomes that look like the result of incremental change.

By itself this doesn't prove anything, but we now have many examples of genomes designed or engineered by humans, and they lack these key diagnostic features. When humans are designing life they use genetic material that crosses species, families, even kingdoms. The human designer leaves fingerprints of his design philosophy all over the scene.

Which approaches zero, tell it to Metmom. I am not the one who divides or multiplies by zero, exploding infinities are too exciting for me : )

With all regrets, I realize that I have joined a thread that while interesting when I had more time, given severe time limitations -- no can do. Just to say that a want science to be science again, and not dicta. The dicta of today is that of godlessness, designer-free evolution -- that is wrong, and also wrong for being dicta.

May all your units of time be used wisely!

Not only that, even the Evos cannot come up with a stepwise explanation for the core processes of the cell. For instance, Williams quotes evolutionary researchers Kirschner (Harvard) and Gerhart (Berkeley) who state that the “Core processes (which they define as cellular architecture, metabolic function, body plan, and modular regulatory functions—GGG) may have emerged together as a suite, for we know of no organism doayy that lacks any part of the suite...The novelty and complexity of the cell is so far beyond anything inanimate in the world of today that we are left baffled.”

What they are talking about, as Williams points out, is the insurmountable hurdle that the autopoietic structure of life presents to evolutionary and origin of life researcher. And the more they learn, the worse it gets for them (and the better it gets of Creation/ID).

[GodGunsGuts]

==Help me out here. Am I supposed to be one of “the Evos”, or not?

Sorry, I wasn't quite as accurate as I should have been. You and a few others have done a fine job grappling with the issues involved re: Life's Irreducible Structure. What I meant to say, is that I pinged dozens of the most prominent Evos on FR, gave them the papers several days in advance, and almost none of them showed up.

F=Ma

Force is the resultant of two components: mass and acceleration.

Anything composed of atoms has mass. Mass is the amount of “stuff” of which an object is composed; but mass is not “weight.” Weight is actualy a measure of the force generated by an object within a gravitational field. Weight is the result of the acceleration of gravity. So we may write F=Ma as W=Mg.

Acceleration is a “change” in velocity OR direction. Where velocity is a measure of an object’s speed in relation to time and space, when changing its position at a constant rate in a straight line. However there is ALWAYS a component of acceleration, no matter how imperceptible, because EVERYTHING in the universe is moving in relation to everything else, and moving along CURVED paths... not straight lines. All mass is effected by gravity fields, and mass produces gravity (curved space time) Velocity is used for calculations having a simple frame of reference, but does not provide the whole picture.

If there is no acceleration component, then there is no energy of motion (kinetic) and thus no force produced; however the acceleration of gravity is always present for any object within Earth’s gravitational field (32fps^2), and likewise the influence of the Moon and other celestial bodies, so there is always the energy of mass in motion, whether it be perceived as a kinetic “force” (momentum) or a gravitaional “force” (weight). Weight is actually the “force” an object exerts on another object due to the influence (acceleration) of a gravitational field. Even when an object is moving at a fixed rate of speed (velocity) there still is a component of acceleration because the object is moving over a curved surface (the earth of other celestial body) or through curved space (gravity) and thus a change in the directional vector is always present.

For any moving object, its acceleration may have a linear or a rotational component. An object in orbit about the Earth, or any other celestial body, “falls” at a fixed rate of speed (velocity) about a center of another mass (the celestial body) and thus while the magnitude of the velocity vector is constant the directional vector is always changing, hence there is a moment of acceleration. This is why orbital mechanics require the use of “the calculus” (derivatives and integration) because there is a continuous dynamic change over time in the x, y or z plane.

Because acceleration is a “change” in speed OR direction, objects appearing to be at rest are actually in acceleration: The Earth is rotating (24 hour period) and precessing (23000 yr period) on its axis, and, in turn, the Earth orbits the Sun (365 day period), which, in turn, orbits within the galactic plane, which, in turn, is in recession from other galaxies... etc. We are always moving... even when dead, for our dust is made of atoms that remain in motion.

In reality, because everything in the universe is in motion in relation to everything else, and all mass is affected by and effects a gravitational field, then force can never equal zero. If F=Ma, and F=0 then transposing the equation to solve for mass: m=F/a; we have m=0/x, which equals zero; but everything has mass. Conversely, we could solve for acceleration: a=F/m, where F=0, in which case acceleration would equal zero; but everything is in motion at some level. There is the mathematical absurdity where if mass or acceleration equaled zero then we would have a=F/m or m=F/a ==> 0=x/0, which is an untrue statement, for we know that division by zero is impossible (except in the case where the numerator is zero... so 0=0/0 gives zero mass, zero force, and zero acceleration: non-existence. (Off topic, the question of whether any object having mass is capable to travel at the speed of light is made impossible by the Lorentz transforms, where as an object approaches the velocity of light, its mass approaches infinity, thus the acceleration, and hence energy required by its propulsion unit, also becomes infinite.)

Nothing is ever at rest. If we go to the molecular scale, we know that molecules move and vibrate (temperature). In the electromagnetic spectrum, photons of light propagate at different frequencies to produce the colors of the visible spectrum. If their frequency is very short (ultra-violet radiation, x-radiation, gamma radiation, cosmic radiation) or very long (infrared, microwaves, television-VHF and UHF, radio) then they are at energy levels outside what the rods and cones of human retina is “tuned” to receive. At the sub-atomic level the electrons rotate about their nucleus so fast (speed of light) that we see them where they were, not where they are. The atoms of gas (solar wind) ejected by our star, the Sun, generate a force when they encounter the Earth’s magnetic field (bow shock wave) and release their kinetic energy in the form of the Aurora Borealis.

So everything is in motion... converting its energy to kinetic or chemical energy, and, in turn, dissipating that energy in the form of heat (entropy, 2nd Law of Thermodynamics, SLT) By the SLT all things fade to black: all energy converts to heat; higher states of energy degenerate to lower states; purposeful organization devolves to random chaos. This law cannot be violated in the natural sphere... organization can only be begun and sustained by something operating outside all laws, both physical and philosophical... something not bound by any law... something greater than law... the author of law, its First Cause... He whom we know as God.

It has been asserted by more than one person on this board that “complexity” is an illusory construct and does not exist.

Which, to me, is about as convincing as the turtle and snake origins story. It comes from a world and mindset that I seem to be incapable of grasping, let alone agreeing with.
