I have seen many an "evolutionist" argue that "the second law only applies to closed systems" without the appropriate caveats. Which is not what nemesis_juggernaut said. Edited by Dr Adequate, : Because for all his faults nemesis_juggernaut is not randman.

Which is not what randman said. True, it's not a direct quote. However, IMHO, given the common creationist confusions about the 2LoT and their tendency to report what they've read inaccurately, I think it's what he meant.

Thermodynamic entropy IS entropy. Yes, of course it is. No one contends with that, least of all, me.
Perhaps some people have latched onto the word to try to claim a scientific basis for why life cannot evolve. Then when someone calls them on it they say "Oh I didn't mean THERMODYNAMIC entropy, I meant some other kind of entropy." "Locigal Entropy" as you call it, is giving a name to what your intuition tells you is true. However, it has no foundation in science. I believe it does because of how axiomatic it is. At present, we simply don't have any way to quantify it. And that is a problem, no doubt. I'm wondering why after all of this time, this law of death has only been played around with by so few scholars. As well, I should probably add that "Logical entropy" is not my definition but someone else's. In fact, I think that kind of is a poor name for it.
In fact we see all kinds of instances where order arises from chaos. Life arising from non-life is the most obvious. Life from non-life? Abiogenesis was debunked by Louis Pasteur over a century ago. There was an Italian scientist in the 1700's who was convinced that spontaneous generation after an ad libbed experiment with rotting meat. He reasoned that if he left meat, thoroughly checked beforehand for maggots, that eventually the meat would produce maggots. From this simple experiment he deduced that life came from non-life. Of course, what he didn't realize is that the putrid meat was attracting flies which layed their larvae in the meat. Eventually the larvae grew inside the meat and became full-blown maggots, which gave the appearance that the maggots sort of grew out of the meat. No one has ever demonstrated that life can ever come from non-life.
But I've seen stratified rock formations and beautiful natural rock arches which are very ordered and arose where previously there was no order. Rocks, sir, are inorganic material, meaning its nonliving. There is no life from non-life in that. If you are now referring to order coming from disorder, I believe you are making a classical error. But, again, I echo the sentiments as before:
It is true that crystals and other regular configurations can be formed by unguided processes. And we are accustomed to saying that these configurations are "organized." But crystals have not been spontaneously "furnished with organs." The correct term for such regular configurations is "ordered." The recipe for a crystal is already present in the solution it grows from ” the crystal lattice is prescribed by the structure of the molecules that compose it. The formation of crystals is the straightforward result of chemical and physical laws that do not evolve and that are, compared to genetic programs, very simple." To be clear, there is no universal law which states that everything everywhere must move toward disorder. You may be confusing 'equilibrium' with order coming from disorder, when in reality it is just disorder coming to a state of equilibrium. If entropy is associated with disorder, and entropy of the universe is headed towards maximum entropy, then how does the ordering process of evolution not directly contravene this law? This is the question asked by dissenters of evolution. "I need scarcely say that the beginning and maintenance of life on earth is absolutely and infinitely beyond the range of all sound speculation in dynamical science. The only contribution of dynamics to theoretical biology is absolute negation of automatic commencement or automatic maintenance of life." -Lord Kelvin “Scientists have often been baffled by the existence of spontaneous order in the universe. The laws of thermodynamics seem to dictate the opposite, that nature should inexorably degenerate toward a state of greater disorder, greater entropy. Yet all around us we see magnificent structures”galaxies, cells, ecosystems, human beings”that have all somehow managed to assemble themselves.” -Steven Strogatz "It is better to shun the bait, than struggle in the snare." -Ravi Zacharias

NJ asks:
Death... It happens. There is nothing that stops it. Life in the physical is intimately tied in to death in every way. Its a constant. ... Why then is their not a specific name for it? There is a name for the process that leads to the death of every individual. You have probably heard it mentioned on this forum once or twice. It is called (drum roll) EVOLUTION. In a forever non-changing environment, immortality is no problem. But environments do change, sometimes drastically. Therefore, 'adapt or die' (referring to the population or species) is the order of the day. This is why, for example, that HIV has been so recalcitrant to being cured. We (and our immune systems) keep trying to change its environment, but the little buggers keep evolving too fast to be wiped out. Individual virus die in droves, but the population, and the disease, lives on. Nature always chooses the easiest, simplest way to do things.* The simplest way to arrange for life to adapt to its changing environment is through reproduction with variation, coupled with death. Even this process is far from perfect and if the environment changes too rapidly, entire populations and species will not be able to evolve fast enough to adapt to the changes and will be extinguished. This is why the great cataclysms of the past are referred to as extinction events. So, death is really further evidence for the validity of the theory of evolution. * I know this phrasing anthropomorphizes nature and makes it sound goal directed when natures processes are in fact always mindless and purposeless, simply stumble to the next step, but our languages derive from our evolved propensity to see tigers behind every wind shaken bush, and evil intent behind every happenstance. So I know of no better way to state this without using some very clumsy wording.

It is called (drum roll) WRATH OF GOD. Before the fall, there was no death, but god's uncontrolled, irrational anger* at some kid's sneaking a piece of fruit from the fruit bowl resulted in every living thing being cursed with a "Life is hard. And then you die." existence. * I know this phrasing makes god sound mindless and purposeless when we know in fact that his every move is well planned and thought out from the beginning of time. It's just that from our perspective, many of god's actions seem like road rage on steroids.

What I got from reading about his work was the existence of life possessing a "grand asymmetry". Dead things do not have this. Future 1/2 eternity survival is part of it. Darwin's "F" line survivability is asymmetric with respect to the perimeter light cone display in my potential quaternionic re-representation. Is chirality one to one and onto the rotation and revolution places of Earth?
I suggested that this is content of the some actual relation between Gladyshevian phenomenological thermodynamics and panbiogeographic track graphs(see claim). I will address the topic directly shortly. About decade ago I cognized that "forms of death" could be related to Fisher's ideas of 'rates of death' and I attempted to get Will Provine interested in the idea. He was not.

quote: Another creationist fallacy. How is that a "creationist fallacy?" Its absolutely true, whether "creationists" assert it or not.

If so, I would very much like to see some incontrovertible evidence.

How is that a "creationist fallacy?" Its absolutely true, whether "creationists" assert it or not. Abiogenesis is the study of the possible ways that life originated on earth - how we went from a pre-biotic world to a biotic one. Pasteur was not studying the origins of life on earth, just the origins of life on rotting stuff (to simplify).

We (and our immune systems) keep trying to change its environment, but the little buggers keep evolving too fast to be wiped out. Individual virus die in droves, but the population, and the disease, lives on. Then you would be essentially saying that another word for evolution is natural selection... That's not the case. Evolution is an extremely large topic theory within biology. But natural selection is not evolution, it is simply a part of a puzzle piece that makes up evolution. The law of death, then, can't be persuasively be described as evolution as a sort of catch-all blanket statement. If we were to assert that, then you might as well refer to gravity as evolution too, on the basis that gravity effects creatures subject to evolution, just as natural selection effects creatures subject to evolution. But more importantly, you are missing the greater part of the question. You are giving me reasons for why evolution can use death. It says nothing about why anything should die, and moreover, why nothing on earth can ever defeat death. The point is that all living materials are temporal. What makes this law?

And yet, the plant will die regardless at some point. The big question is, why? So that individuals aren't forced to compete with their progeny. Individuals who are forced to compete with their ancestors for resources are selected against compared to individuals whose ancestors conveniently remove themselves from competition via death. Hence, living cells undergo programmed obsolescence, a process called "apoptosis." Hence, death pre-programmed into our very genetics (telomeres.) It doesn't have anything to do with "entropy" of any kind, and everything to do with natural selection favoring the offspring of those who remove themselves from the population so that they don't steal resources from their progeny. Thermodynamics is relevant to biology - at the biochemical level. And it's known that none of the chemical life processes violate the second law - indeed, the second law makes the chemistry of life possible. Life is not in violation of thermodynamics, it exists as a result of it, as a result of thermodynamics making certain chemical reactions energetically favorable under the right circumstances. The evolution of livings things over time has nothing to do with thermodynamics, because it's not a system. Evolution is a description of what populations of living things do over time, not a description of those populations as some kind of system with input and output. Thermodynamics is irrelevant to the evolution of populations.

Who says nothing on earth can EVER defeat (programmed) death? It's not because nothing has been able thus far, that it could never happen. One of the bigger reasons is that no lifeform thus far ever *cared* about it, such that mindless evolution was the only factor. It could well be that our desire to live longer might enable us to solve the engineering problems. (although because of the very un-human and un-systematic design process of natural selection, it might always remain out of reach because too many factors are intertwined in too much a complex way to ever re-engineer things adequately)

It says nothing about why anything should die, and moreover, why nothing on earth can ever defeat death. Things need to die because there are finite resources. Nothing we know of has avoided dying so far because such a thing will require a higher level of technology than anything has yet achieved and the random mutation that would do it simply hasn't happened.

quote:In this thread, a distinction was made between thermodynamic entropy (a redundant phrase) and logical entropy (a label given to a concept which is neither axiomatic nor scientific.) I was pointing out that entropy is a thermodnamic quantity, not a logical contruct. quote:First of all, "logical entropy" is not axiomatic. In any event, as soon as an axiom is challenged, you cannot rely on its status as an axiom to refute the challenge. You must provide evidence for its validity. quote:I agree. Whatever you are talking about has nothing to do with entropy. I think other posts have beaten me to the punch about Pasteur's experiments, which would only apply to this discussion if someone were contending that the first lifeforms sprang forth from chicken broth or rotten meat. In fact abiogenesis is the leading scientific theory for the origin of life on earth. Maybe God did just throw us here, but despite a few thousand years of looking, nobody has found any evidence of that happening. I am not confusing equilibrium with order coming from disorder. The systems I referred to are not in equilibrium when considered on large time scales. Random events over time have created ordered structures. A natural rock arch is very different from a crystal lattice. There are not fundamental physical laws which say rocks must form in that structure. Yet there it is, perfectly "created" with enough material in the correct places to support its own immense weight, seemingly violating your "axiom" of "logical entropy"
quote: Entropy is often defined as a measure of disorder. This is a weak definition at best. It is a quantity which must increase in order to satisfy the first law of thermodynamics when heat is isothermally added to an thermal resevoir. Even that definition is at best incomplete. In the universe's march toward maximum entropy, ordered structures will ebb and flow out of existence. We see it all around us. Gas has condensed into stars which have associated into galaxies, which have associated into local groups of galaxies. Nebulae have consensed into solar systems with planets which fall into orbital resonances. There is a great deal of order coming from disorder. None of this violates the 2nd law of Thermodynamics.
