That ID is scientifically vacuous is once again beautifully exposed:But the real danger is not string theory's lack of experiments --- it is the misrepresentation of what scientific theories are all about. Sure, falsifiability is a key component of the scientific method. But there is something that matters more: the power of explanation. History reveals that the structure of a theory itself --- its internal mathematical consistency, its scope, and its beauty --- often determines whether it is accepted as science.
Or "As Columbia University physicist Brian Greene says, "The theory of intelligent design is not only not falsifiable; there is simply no way to test it. But that is not the main reason it is not science. The main reason is, that ID does not actually explain anything. When we ask, "Why is the world the way it is?" it answers, "Because it was designed that way." The world is the way it is because it is that way. That might be the furthest from a useful, satisfactory explanation you can get.
For an indepth interview with Brian Greene on Nova click this link At the "He Lives" website David Heddle who describes himself as a 'reformed nuclear physicist" discussed Susskind's latest book titled "The Cosmic Landscape: String Theory and the Illusion of Intelligent Design ". In Susskind's Sophie's Choice, Heddle describes his 'objections' to Susskind's solution to the anthropic principle. Since Heddle has much invested in his Cosmological argument, it should not come as a surprise that Heddle objects to Susskind's arguments. Ironically however he seems to miss the irony in the following statement:"String theory is a work in progress. It is science because in its decades of development it has always adhered to the well-established methodology of theoretical physics. So far, we have not revealed enough about string theory to extract detailed predictions that are within reach of today's technology. If, however, we believed that this latter goal of testing string theory were permanently unattainable - as it most certainly is for ID as currently presented - we would no longer work on the theory. As of now, there is no way to tell how things will pan out. But that's what theoretical physics is all about: Devise theories, analyze them with rigorous mathematical tools, do your best to extract experimental predictions, and test them. No one can predict how long each individual step in this progression will take." So be patient!
— Brian Greene
What Heddle forgets to mention is that Susskind's 'multiverses' are a direct consequence of the well supported inflationary theory. Intelligent Design however has no such basis in theory. In other words, why should David's cosmological argument for ID be seen as scientific when it fails the same standards? Let me try to give my best understanding of string theory. String theory tries to combine Relativity and Quantum Mechanics into a single theory. Since there are occasions where we need to apply both relativity and quantum mechanics, such a theory is needed. An early attempt to extend space to 5 dimensions was the Kaluza-Klein compactification. By expanding space to 5 dimensions, electro magnetic force and gravity could be unified. The 5th dimension's size was so small however that it remains invisible to direct observation. When the weak and strong forces were discovered, the Kaluza Klein solution seems to have failed as it could not explain these additional forces. By extending the dimension to 10 or 11, string theory however can explain and unify these forces. At the moment most work is done to reconcile these models with known principles and observations. One of the aspects String theory deals with better than particle physics is the treatment of particles of having zero size, leading effectively to singularities. In String theory the particles interact at a Planck distance which resolves the problem with particles.Susskind has presented the physics community with what is, for some (not this writer), a Sophie's Choice: a hidious, complictated, unfalsifiable String-Theory Landscape, or Intelligent Design. Susskind rocks.
— David Heddle
Link An interesting overview of String theory and what has been accomplished is given hereIn the original work of Kaluza it was shown that if we start with a theory of general relativity in 5-spacetime dimensions and then curl up one of the dimensions into a circle we end up with a 4-dimensional theory of general relativity plus electromagnetism! The reason why this works is that electromagnetism is a U(1) gauge theory, and U(1) is just the group of rotations around a circle. If we assume that the electron has a degree of freedom corresponding to point on a circle, and that this point is free to vary on the circle as we move around in spacetime, we find that the theory must contain the photon and that the electron obeys the equations of motion of electromagnetism (namely Maxwell's equations). The Kaluza-Klein mechanism simply gives a geometrical explanation for this circle: it comes from an actual fifth dimension that has been curled up. In this simple example we see that even though the compact dimensions maybe too small to detect directly, they still can have profound physical implications. [Incidentally the work of Kaluza and Klein leaked over into the popular culture launching all kinds of fantasies about the "Fifth dimension"!]
Another major flaw of the standard model is that it describes the interactions of elementary particles but not where they come from. This knowledge is known through experimental data only. String theory should explain where the four forces come from, why the particles that we see exist, why these particles have the masses and charges that they do, why there are four spacetime dimensions that we live in, and the nature of spacetime and gravity 3. As strings move through time, they trace out a worldsheet similar to the worldlines of point theory. They vibrate, and these different vibrational modes give rise to the various particles that we can "see". The different modes are seen as the different masses and spins. String theory possesses the necessary degrees of freedom to describe all known interactions--something that cannot be said about the standard model. These degrees of freedom arise from the spacetime dimensions that strings live in. Whereas we can only see four spacetime dimensions, string theory has ten or eleven. Six or seven of these dimensions are curled and thus effectively invisible; the idea is that motion in these compacted dimensions gives rise to the properties of the particles 2. Kaluza-Klein showed that if a fifth dimension were compacted and added to our spacetime, it would allow a four dimensional theory of general relativity plus electromagnetism. If the electron is allowed this extra degree of freedom, then the photon arises and the electron obey's Maxwell's equations 3. Elimination of the extra dimensions through Kaluza-Klein compactification or constrainment of matter and gravity into a three-dimensional subspace called the three brane is called braneworld theories 5. In the case of Kaluza-Klein compactification, the extra dimensions are wrapped on Calabi-Yau Manifolds and Orbifolds that are far too small to be seen with modern technology 2. The extra degrees of freedom afforded by string theory explains more than electrons. They predict the existence of the graviton, include the same gauge theories as the standard model, and predict supersymmetry at low energies such as the electroweak scale. Current particle accelerators are only reaching to about 10^(-16)cm, so point-particle approximations are still successful as approximations. Once accelerators reach smaller scales, however, supersymmetry may be revealed and point-particle approximations may prove to be incorrect 4.

The real difference between String Theory and ID is this: the Stringers are on a constant search for an experiment that can test their theory, while the IDers resist any attempts to find such an experiment for their theory.
PvM · 9 February 2006
Good point. But then again, there is no theory of ID to test :-)
Mike Elzinga · 9 February 2006
There is also other historical precedent for the type of work going on in string theory that the ID crowd doesn't understand. Mach hounded Boltzmann into depression over Boltzmann's work on statistical mechanics because atoms could not be observed even in principle, or so thought Mach. Nevertheless, due to the work by Boltzmann, Maxwell, Gibbs, Einstein, Bose and others, the macroscopic behaviors of gases, then solids, then plasmas finally began to be explained accurately in terms of the behaviors of the underlying microscopic behaviors of atoms and molecules and the laws of classical and quantum mechanics.
Now we can "see" and manipulate atoms using scanning tunneling microscopes and their derivatives. But all along the path, there were experimental checks that verified the validity of the theory. Even with string theory there remains the possibility that someone will find a clever experiment within the range of technology that will check consequences of the theory. It has happened many times before because there are clear links to experiments, even if these are gedanken experiments for the moment.
RupertG · 9 February 2006
Where are the string theorists lobbying for their idea to be taught in schools? Where is the PR offensive? Where is the theory's Dembski, where its Behe, where its Fleischmann and Pons?
Surely no new scientific theory can be taken seriously unless we teach the controversy to teenagers first.

Daryl Cobranchi · 9 February 2006
You unfairly malign Fleischmann and Pons. They were (and AFASIK still are) experimentalists. Yes, the results do appear to have been in error. But there were results that could be replicated (or not). Pons might have done poor calorimetric measurements, but that does not make him a Dembski.
[Full disclosure: I was in the Chemistry Dept. at the University of Utah when Pons, Fleischmann and the unnamed grad student published the Cold Fusion paper.]
Corkscrew · 9 February 2006
The maligning is even worse than that - IIRC it wasn't even their decision to hold the infamous press conference that caused so much trouble, it was the university's decision. And this was with results that were not only gained by valid scientific (if ultimately mistaken) approaches, but with an hypothesis as to causation that was actually broadly consistent with the rest of science. There have even been tantalising hints over the years that maybe they were actually onto something.
And they still got torn apart by the academic community over it. Real scientists, respectable individuals working inside their field of expertise, got minced for not going through the proper steps. And that's pretty much as it should be. But it does rather kill the IDiots' claims of persecution.
[Full disclosure: my dad worked for Dr Fleischmann as a grad student. No, he wasn't that grad student.]
Renier · 9 February 2006
Thanks for the article. The way you explained the dimensions was a big help to me. Just a question.
Renier · 9 February 2006
Sorry. Question. Gribbon explains in his book "Schroedinger's kittens" than ST (String Theory) will do away with the CC. He fails to mention in what way. It is because ST will explain the CC or that ST does not need any CC in it's equations?

Andrea Bottaro · 9 February 2006
Corkscrew and DaryL:
Wow, it's a small world, innit?
About P&F, I know close to nothing about nuclear physics, but I thought their results were NOT consistent with current theories, and in fact one of the things that immediately suggested that something was wrong with their conclusions was that, if their measurements were correct, the experimenters would have been practically incinerated by the radiation emitted by their system.
Also, apart from the press conference (which clearly they should have refused to participate in, regardless of who set it up), I think the reason they were "chewed up" was that they hung on to their conclusions well past the moment they were shown to be extremely fishy, in part abetted in this by spurious results obtained in other labs, as well as by cheer-leading from outsiders and other self-proclaimed "iconoclasts". (I think that's where the similarity with ID is, not in their methods, which were indeed scientific.)
A long time ago I read what seemed a pretty good book (if rather negative about P&F) about the whole story, "Bad Science" by Gary Taubes.
Back to string theory now.
Laser · 9 February 2006
You forgot one item in your list of differences between string theory and ID:
4. If experiments show that string theory does not correctly explain observable phenomena in the universe, then string theory will be discarded. That is, scientists working on string theory will acknowledge it if their theory cannot be reconciled with experimental data. ID proponents will not change their minds, no matter what experimental data shows.
AC · 9 February 2006
Renier, my understanding is that string theory would explain the CC. The CC is the vacuum energy density, which is related to quantum gravity, which string theory seeks to describe.
Rolf Manne · 9 February 2006
I would like to go off in another direction: astronomy. It is well-known that Newton could not explain the relative motion of the planets Jupiter and Saturn. I have read, although I have no reference, that as a kind of explanation he postulated "the intermittent action of a deity".
About a hundred years later Laplace did the calculation with the newly invented technique of perturbation theory to the 3rd order. Newton is said to have done his calculation only to the 2nd order. - Laplace had thus good reasons for answering Napoleon that he had no need for a hypothetical god in his scientific work.
How can a believer in ID creationism be sure that he does not make the same mistake as Newton?
yellow fatty bean · 9 February 2006
At every string throry seminar I ever attended, at the end an HEP experimentalist would always ask "Is any of this testable ?". The reply was walways along the lines of "Yes, but you dimwit experimentalists haven't been able to build a big enough particle accelerator yet"
Good Times.
It would be nice if there was just one proposed falsifiable ID experiment out there, but I haven't hread one.
Glen Davidson · 9 February 2006
It's simpler than that, really. One may readily come up with a testable model of intelligent design of organisms, it's just that when one does this one finds that ID has already been falsified.
Once evolution began to make its predictions, life was found to show the marks of evolution, while intelligent claims that life was designed evaporated in the face of vestigial organs and rather unlikely "designs" which are predicted by evolution, and which are actually predicted not to exist by any rational/empirical concept of design. That is, ID is falsifiable, if one simply brings normal design expectations to judge if organisms have been designed or not. When this is done we find that organisms haven't been designed, rather they are well explained via evolution.
The resurrected concept of ID avoids the problem that it has been falsified by denying the meaningfulness of every reasonable test that we bring to it. While current ID isn't falsifiable, this is simply because it refuses to accept expected tests of ID because these refute the concept. Therefore, it isn't due to the nature of ID that it cannot be tested (the designer doesn't need to be known per se, however this posited designer must follow fairly normal expectations that we have for a designer, or we would have no means to evaluate the design claim), it is merely the denial of reasonable testing criteria which makes ID untestable in its current form. IDists refuse any criterion that will allow ID to be falsified.
We really shouldn't allow anyone to confuse the issue, since confusion of standards is what ID feeds off of. IDists cannot subject their idea to testing because they already know that normal tests do not find design in organisms. Thus they oppose science itself, and demand that an unknown designer with unknown design criteria, unknown capabilities, and unknown purposes (even in principle) for its designs, be considered to be "science". They deliberately demand that their ideas must be accommodated within science (or at least science education) after modifying the old claims so that they can no longer be tested, as Paley's claims were able to be tested. This is why ID is the most malign form of creationism yet.

String theory is not more scientific than intelligent design. At least with intelligent design, there are many tangible artifacts one can analyze and infer conclusions from. String theory postulates ideas that are outside the observable universe. At least that's the feeling that I'm getting from the article I linked to above.
Steuard · 9 February 2006
First, responding to Renier: The cosmological constant has been a puzzle in physics for years, and no theory has ever made a reasonable prediction for its value.
For a long time, every experiment showed that its value was zero to within the experimental uncertainty. At that time, most physicists expected that there must be some physical principle (as yet unknown) that required it to be zero exactly. So people expected that a "theory of everything" like string theory would imply such a principle... but nobody could find it. I'm guessing that the book you mention was written in that era.
More recently, more precise experiments have discovered that the cosmological constant is non-zero, but very, very small. So now, physicists working on string theory have stopped looking for a principle that sets it to zero exactly, and are instead looking for mechanisms that could lead to such a small value. (Some of my own work has been on that topic.) Some still hope that string theory will eventually predict the exact value, while others now suspect that different values might be allowed in different (and very distant!) regions of the universe.
Next, "yellow fatty bean": In most of the string theory seminars that I've been to (or given), the speaker has responded to the question of experimental tests by stating that both the theorists and the experimentalists would need to do better for predictions to be testable. Personally, I figure that we theorists have the farthest to go in bridging that gap: experiment has been making great progress for decades, while we're still trying to figure out the underlying structure of the theory. But that's the fun! So I agree: Good Times.
Finally, just as a personal plug, I've got slides from my own "Introduction to String Theory" talk on line for those who are interested; it's aimed at people who took some physics years ago but may not have done a lot with it since. I like to think that I've described string theory's extra dimensions and some of its differences from traditional particle physics reasonably well (at that level). The address is:

JONBOY · 9 February 2006
Here is perhaps a more simplistic explanation for "non" scientist who are interested
String Theory
In String Theory, the myriad of particle types is replaced by a single fundamental building block, a `string'. These strings can be closed, like loops, or open, like a hair. As the string moves through time it traces out a tube or a sheet, according to whether it is closed or open. Furthermore, the string is free to vibrate, and different vibrational modes of the string represent the different particle types, since different modes are seen as different masses or spins.
M-theory
Apart from the fact that instead of one there are five different, healthy theories of strings (three superstrings and two heterotic strings) there was another difficulty in studying these theories: we did not have tools to explore the theory over all possible values of the parameters in the theory. Each theory was like a large planet of which we only knew a small island somewhere on the planet. But over the last four years, techniques were developed to explore the theories more thoroughly, in other words, to travel around the seas in each of those planets and find new islands. And only then it was realized that those five string theories are actually islands on the same planet, not different ones! Thus there is an underlying theory of which all string theories are only different aspects. This was called M-theory. The M might stand for Mother of all theories or Mystery, because the planet we call M-theory is still largely unexplored.

It's good to see people who understand string theory much better than I do contribute to this thread. Steuard your webpages are very helpful to me. My understanding of physics is enough to get me into trouble, your pages are enough to get me out of trouble again :-)
Exploring M Theory and strings is quite interesting since for a long time I had a limited grasp of what it was really all about. My goal was to show that ID and string theory are only superficially 'similar'
JONBOY · 9 February 2006
Very sorry for the double post, the last part should have read.
There is still a third possibility for the M in M-theory. One of the islands that was found on the M-theory planet corresponds to a theory that lives not in 10 but in 11 dimensions. This seems to be telling us that M-theory should be viewed as an 11 dimensional theory that looks 10 dimensional at some points in its space of parameters. Such a theory could have as a fundamental object a Membrane, as opposed to a string. Like a drinking straw seen at a distance, the membranes would look like strings when we curl the 11th dimension into a small circle
Anteater · 9 February 2006
Hello PvM,
Thanks for the response. I agree String Theory may be a beautiful theory. But some may say ID is also elegant.
I personally see no difference between String Theory and ID in terms of metaphysics. Both are on the same footing.
As the nature article suggested, if one can postulate a theory that deals outside of the observable universe, then what prevents one from saying that the universe was the product of intelligent design?
You make a good point by saying that we can potentially observe the effects of String Theory; however, ID claims almost the same point -- they're observing the effects ('artifacts') of design.
Hope I am making a little sense. Thanks.

All the fine distinctions between ID and ST discussed here are stretched and convoluted.
(1) ID proponents also argue that ID theory follows "logically from observations."
(2) Both theories cannot be falsified right now but can "in principle" be falsified, if that counts. If we could duplicate the conditions on the early earth, either in a lab on earth or find another identical planet, and life evolved in exactly the same way, that would come very close to falsifying ID.
(3) ID proponents argue that ID theory provides a powerful framework that explains various mysteries.
The fact is that working scientists are not philosophers. They don't go walking around with a checklist in their heads pertaining to what constitutes science. There are no official rules that a paper needs to satisfy in order to qualify as science. The various steps of the so called "scientific method" exist primarily in story books, not the real world.
In the real world scientists propose theories that they feel in their gut advances knowledge or understanding about the behavior of nature. As long as a theory is not contradicted by data, it gets to live another day. The ID proponents believe ID does that. The real reason ID is automatically disqualified by the established scientific community is that it contains a fatal flaw - it implies God. They prefer to artifically restrict the domain of science to so called "natural" explantions, the truth be damned.

Incorrect. ID proponents claim that ID follows from observation. They do not 'argue' it. In addition, there is no theory of ID. If you believe otherwise, articulate that theory. Please include all hypotheses, falsification tests, research, corroboration from other disciplines, etc.
If you buy into the hype that intelligent design can be "inferred" from evidence that we're not here by accident, then it is inferred by the anthropic principle if the multiverse doesn't exist, if, as the co-founder of string theory, Leonard Susskind, says... "the appearance of intelligent design is undeniable".
His is a scientific interpretation that only fails to support ID because he is confident that he can lose the so-called, "implication" in the multiverse, but he'll have both feet in his mouth if string theory doesn't pan out, which I don't believe that it will.

one of the best descriptions and explanations of the current concept of scientific method is this.
Observation and description of a phenomenon or group of phenomena.
Formulation of a hypothesis to explain the phenomena. In physics, the hypothesis often takes the form of a causal mechanism or a mathematical relation.
Use of the hypothesis to predict the existence of other phenomena, or to predict quantitatively the results of new observations.
Performance of experimental tests of the predictions by several independent experimenters and properly performed experiments.

Unless I have missed something in the ID literature, I have not been able to find anywhere in their writings a program of genuine research that they themselves have carried out or propose to carry out.

What can't be inferred from design is "intelligence", without direct proof, since any satisfied physical need will derive the same results.
This is not commonly understood, because everybody is afraid of the implications for specialness that are inherent to the physics of the anthropic principle.
Because they buy into the creationists hype and they *believe* that evidence that we're not here by accident constitutes evidence for god.
Soooooo... they invent rationale that downplays the whole reason that it was named the anthropic principle, instead of acting like real scientists, and trying to find some good reason for why it might be true... WHICH BI-PASSES THE NORMAL SCIENTIFIC METHOD ROUTE!!!

PvM: Next time please preview before you post Island.. I cannot correct all the XML errors
I am quite familiar with all these lines of argument. The basic point remains: the anthropic principle is meaningful only if we violate the basic principle of "nothing special here."
Consider: how could tell the difference between a sole universe where life occured to ask the question of how life occured; and a multiverse situation? You can't. It would look the same.
You forgot to first look for a good physical reason why it might be true... Why is that?
The AP falls from the observed universe not theoretical speculation about fairys and unproven universes... sorry, those don't fly against the implications for specialnees that fall from the observed universe, unless you can prove that a multiverse is necessary to the one true theory of everything... but that ain't gonna happen, so give it up and find a good reason why we might be special to the process.
Even your physics lecture only points out that the basic meaninglessness of the AP is only "mildly unsatisfying". In other words, we don't find it emotionally satisfying. That doesn't make the AP an actual philosophical or logical problem.
The anthropic/cosmic coincidences note that life only appears balanced between diametrically opposing runaway tendencies... I should think that Evobiologists could make good use of that information if they we're pre-prejudiced against the AP.
But... the AP is incomplete, because it was taken from a flawed large numbers hypothesis. Fix the flaw and you necessarily complete the principle.

Yes there may be a variety of physical reasons to explain the anthropic principle such as multiverses, selection, chance and even necessity (this universe is the only possible one). None of these makes us necessarily 'special' just lucky...

What happens to specialness when a real scientist points out that the anthopic principle readily extends and cannot be restricted from every last banded spiral galaxy that exists on the same evolutionary "plane" as we do with respect to the requirement of the principle that we occupy a special "location" and time in the history of the universe?

If the only way we'll ever create in the lab anything we can (mostly) agree on is 'life' is if the Designer uses us as His agents, then I can only pray that He get up off His duff and get cracking.
Meanwhile, we're stuck with the Clauser Conundrum: if we DO create life in the lab, that shows the Designer did it. If we can't, it STILL shows the Designer did it, only long ago. And if we can't agree whether what we produce is 'life', that only shows the Designer is playing with us.
As for ID explaining mysteries, I have to agree that it does so reliably. Why do we argue? The Designer wills it. When will we stop? When the Designer wills it. Is there such a thing as absolute truth? The Designer tells some of us yes, tells others no. All our questions are answered.
What the Designer NEVER does is tells us our opinion is wrong.

Let me propose a method if this is to continue:

2) Commentary is allowed from outside sources regarding veracity of sources to ascertain if anyone is, essentially, using a completely bogus source.
3) Both sides post a rebuttal to the other sides argument.
4) We stop and let everyone else judge for themselves.
Thus, by necessity, you're either going to need to both have a positive argument for your position, or you're going to get railed. Also, if the other side is wrong, it should be self-evident to a reader.

This is where it fell apart for me, with the denial of the fact that we should first look for evidence why we might be special to the process.
I'm not going to try too hard to prove anything, until somebody admits that, or I can know that I'm guaranteed denial of the following quoted from the physics lecture:
In the past 20 years our understanding of physics and biology has noted a peculiar specialness to our Universe, a specialness with regard to the existence of intelligent life. This sends up warning signs from the Copernican Principle, the idea that no scientific theory should invoke a special place or aspect to humans.
Why might this be true is the first question that should be asked before that other lame lists of crap gets rationalized.
There is only one reason why it never is...

Glen Davidson · 9 February 2006
What strikes me about the "we are special" premise that goes into the anthropic principles, as well as into ID, is that it seems to be born from the actual lack of any obvious specialness. Lightning happily blasts our brains out, volcanoes smother cities with their inhabitants (and just wait for the supervolcano), the wonderful solar system built just for us targets us with mighty big rocks and chunks of metal, and we may yet be destroyed by a supernova. What do purpose-desiring humans often do in the face of this callous destruction of life? Seek meaning, find the bare minimum of conditions for the existence of life, and then baptize those conditions as "special" (usually in a religious vein, but not necessarily).
It's kind of touching in its primate longings, of course, and if we "neo-darwinists" had nothing else to cling to in order to make us special, it might be our primate response as well.
However, most myths and legends from the past have included not only the primate sense of our being "special", but also told of why life is mean, harsh, uncertain, and fated toward death. Paradise was given once, however it is lost and we have the mythic reason why the gods have turned their backs on us, or perhaps are even destroying us for their sport. I like the Babylonian myths in particular, since they tell us that the gods wanted some slaves to do their bidding, producing the smoke of meat for them, making temples for their egos, etc.
The universe is amazingly unsuited to life in the vast majority of its space, and apparently even in the systems of matter that we find. It is probably safe for us to conclude that not many stellar systems in the Milky Way have evolved intelligent life, and even the ones that have are going to become hostile to life eventually (we might escape for some time by moving to other systems, but we can't run ahead of entropy's destruction forever). The whole universe will wind down eventually, and as far as we can see, life will vanish and be like it never was. I really don't know how such an end to the universe is to be understood as existing in some special relationship to life, rather the indifference of the universe and any possible creator of the universe appears to dominate throughout the existence of the universe.
We're always trying to escape death, as a species and even more so as individuals. And why not? However, everything we have learned points toward our eventual demise, as both species (or whatever taxonomic category we might choose) and as individuals. Perhaps the death of all life is what the universe and its creator is the real goal of the universe?
Well, I doubt it. We're just a warm little spot of consciousness appearing momentarily out of the clash between life-destroying heat and violence and the cold stillness of ever-expanding space. We have reason to enjoy it and to think our world as special in relation to our own lives and values, but we have yet to find anything that suggests that the universe is made to do anything except to evolve to the state at which life can no longer exist.

PvM · 9 February 2006
The argument by Schneider and Kay seems to be along the lines of the work of Prigogine that life exists far from equilibrium. By moving away from equilibrium, gradients arise which can be used to increase complexity. While this may explain why life may have been inevitable in this universe it does not answer the larger question of specialness. Entropy can decrease locally at the expense of increased entropy elsewhere. Dissipative structures and complexity are nothing much new though. Until Island explains his arguments in more detail I am not sure what the relevance is of his statements. I am somewhat confused how he moved from an attempt at discourse, to ad hominems when hardly provoked...

You misattributed some quotes to Island that were mine. Be careful with that. I'm also not launching an ad hominem at anyone, because my objections are:
1) Not statements of character or personality.
2) Directly relevant to the issue at hand.
It's not an ad hominem to point out someone is a child abuser if they are applying for a job at a daycare. Likewise, it's not an ad hominem to point out that multiple people in this thread are arguing with one-liners instead of having a legitimate debate based on information when, of course, the point of the threads is to discuss ideas and debate.
Or maybe I'm wrong and it is to flame with one-liners, in which case I would withdraw my objection.

Luckily, talk origins has that paper on file, too, I was talking about the fact that "Into the Cool" is no less scientific that Lenny's book:
http://www.talkorigins.org/indexcc/CF/CF001.html
Several scientists have proposed that evolution and the origin of life is driven by entropy (McShea 1998). Some see the information content of organisms subject to diversification according to the second law (Brooks and Wiley 1988), so organisms diversify to fill empty niches much as a gas expands to fill an empty container. Others propose that highly ordered complex systems emerge and evolve to dissipate energy (and increase overall entropy) more efficiently (Schneider and Kay 1994).
ID is not a positive argument.
I never argue for ID.
PvM · 9 February 2006
As far as I can understand Island's arguments, it is that there is a purpose in the universe but not one which points to intelligent design but rather to
"If, for example, I say that our work-efficient predisposition is evidence that the second law of thermodynamics is the reason why we are here here, and that the flatness of the universe points toward the underlying reason why humans have the inherent predispostition to design stuff that efficiently increases entropy, like; nuclear reactors, high-energy lazers, particle accelerators, etc."
combined with
"... and that this also serves as hard empirical evidence that there exists an entropic preference toward intelligent life that no other life-form enjoys."
I find the word purpose somewhat confusing here since as with Behe, it refers to functional. In order to extract energy, in order to 'survive' life has to exist away from equilibrium. By existing away from thermodynamical equilibrium, complexity arises inevitably, thus life inevitably will increase in complexity.
However to call that 'purpose' seems to strain the meaning of this term.
I do agree though that ID may conflate the different meanings of the word purpose, something which can be resolved far simpler by showing that all they are talking about is function.
The SLOT generates new complexity (variation), selection culls that which works and life 'evolves' towards increasing 'complexity'. Although it does not have to. Most life on this earth has remained relatively non-complex and in many ways seems to be far more succesful that humans. Heck some bacteria thrive on plutonium or in high temperaturs, or high acidity. Us poor humans are forced to maintain a comfort zone which is relatively narrow.

FYI... All that is required for this to be a valid hypothesis:
I pose the assertion that we are here to *efficiently* increase entropy.
As macroscopic evidence for this, I offer that the human evolution has enable us to *progressively* accomplish this from the moment that we harnessed fire to the fact that intelligence has without any doubt proven to enable us to tap into energy sources that we would otherwise not been able to touch.
I don't have to proof this theory yet, for this to be a valid scientific question that merrits further study.

It is a fact that random non-uniformities in the expanding universe are not sufficient to allow the formation of galaxies given the rapid rate expansion, since the gravitational attraction is too weak for galaxies to form in any practical model of turbulence that is created by the expansion itself, so the entropy of the universe is less than it should be unless far-from-eqilibrium dissipative structures, like us and black holes, (which most definitely do arise via the formation of large scale "sites that are conducive to life"), serve to balance this *most-apparent* entropic debt via high-energy contributions to the entropic process.
First principles supercede ill-conceived anti-anthropic rationale, every time, and the anthropic principle is the difference between an expanding universe with structure, and one that has none.
Not to mention what they do to inflationary crackpottiness, stringy theories, and uncertainly derived falacies that lack causal meaning.
The second law of thermodynamics in an expanding universe says that entropy always increases... but that's all that it really tells us, so be careful what you project to before figuring out how biocentric structuring might actually make it perpetually so.
island · 9 February 2006
SLOT by itself may not be sufficient but yes, variation is a requirement for evolution to act upon. You seem to see this as a ToE, I see it as a consequence rather than a cause.
Actually, I believe that I have good reason to believe that the TOE, is the ToE.

It never hurts to call well established and well supported theories as crack pottiness.
All theories become cracpottiness until proven beyond doubt when new information, weird physics, or unprovability are at play. I'm sorry that you don't know anything about science.
While I can appreciate the role of black holes, I doubt that our influence on the universe has been in any form 'measurable' or relevant.

PvM,
Your being so ready and willing to dispose of certain questions, such as "why are we here" by just declaring "we do not know" and merrily walk away from the issue, in contrast to other questions where theories are called upon to explain phenomena, betrays the artifical restriction on science I spoke of.
If Darwin would have applied the same attitude to the issue of the origin of the species, he would have just declared "they are just here" and "we do not know" and moved on to other things. The point of science is not to walk away from issues by shrugging our shoulders and declaring that we just do not know.
So why the selective application of this approach on the part the scientific community? I claim it is due to the big elephant lurking behind certain issues, a monster many prefer not to face.

String theory solves many of the questions wracking the minds of physicists, but until recently it had one major flaw --- it could not be tested. SLAC (Stanford Linear Accelerator Center) scientists have found a way to test this revolutionary theory, which posits that there are 10 or 11 dimensions in our universe.

Sorry, Donald M., but Ratzsch is trivially easy to refute, even if one were to grant that his argument is formally correct.
Your use of Ratzsch engages in a nasty equivocation, up to the level of begging the question.
The so-called prescription of methodological naturalism falls to Ratzsch's argument, or your abuse of it, only with the shift to an alleged proscription of design.
But that's really the question isn't it? Is all design natural? Some of us would say yes, although exemplars such as Dembski, Cordova, Behe, and Fafarman, in all his myriad pseudonyms, might lead us to suggest they were the products of unnatural design. Or at least unnatural acts.
If you want to rely on Ratzsch's argument, you have to show that the prescription of methodological naturalism entails a proscription of design. Since we have countless examples which would refute this, your efforts are doomed from the start.
Sort of like teaching ID in schools, but for reasons of natural law rather than reasons of human law.

Hey Donald, are you gonna answer my questions this time before you run away? Or aren't you.

artificial in what sense then Donald M? In that it makes science workable?

Good. I'm glad to know its just a rule of thumb that can be set aside when not not needed. As to its being a "necesity of the very fact of the investigation", that would only be the case if your knew a priori that only natural causes were operational to bring about a certain phenomenon. In other words, claiming MN is necessary to investigation begs the question
Operationalize, please.
Please show (do not tell) how this can be done. As it is, you argue circularly.

What configuration of strings leads to each of the known particles? (electron, neutrino, up and down quarks, also the 2nd and 3rd generations of those, and the antiparticle of all of them, and also force carrying "particles".)

To dismiss intelligent design as being science because it is untestable is correct. At best it is a logical reasoning, more like a mathematical proof. If you accept its underlying postulates then you can build a case for it. However, to dismiss it as being nonscientific because it is an ad hoc explanation of observation is completely incorrect. The history of science is full of ad hoc explanations for phenomena. Ptolemy's epicycles, the alphabet soup of subatomic particles prior to Gell-Mann's work, Planck's work on quantum mechanics, Fraunhofer's work on stellar spectra, and the heterotroph hypothesis just to name a few. Ptolemy's cosmology was the definition of ad hoc, but it was science because it was testable, if ultimately incorrect. Planck didn't believe a word coming out of his own mouth. For him, Planck's constant was a giant fudge to make the calculations work. Indeed you can argue that Punctuated Equilibrium is nothing more than an observation of the fossil record. People make a big deal about how it is an alternative to natural selection, yet there is no new "theory" to explain it. Did the study of subatomic particle or atomic spectra miraculously become science on the day Einstein proposed a theory for the photoelectric effect, or Bohr produced moving electrons? No. The only criteria that applies to science is its falsifiability. Can it be proved wrong or not. On that basis ID is not science. However, when a respected Nobel Laureate such as Sheldon Glashow points out that string theory is a completely safe theory and can never be tested, you must say the same about string theory. What this debate really shows is the deep prejudice academia has against people of faith. String theory meets approval because it is a secular philosophy. ID meets scorn because the people who propose it are people of faith. No one in the scientific community bats an eye when Francis Crick proposes that life on earth began from extraterrestrial infection, an equally untestable theory and about on par with an intelligent force guiding the evolution of life. If we find life on another planet, it doesn't mean that it was the source of life on earth. If we don't find life on another planet, you can always fall back on the "we haven't found it yet" or "we don't know how to look for it" excuses (rather like the we haven't built a particle accelerator big enough to test string theory argument). A completely safe "theory" that still merits the odd biology textbook quote. I contend that Crick's musings are tacitly accepted, as is string theory, more because of who says it rather than what is said. For a community that requires, and largely achieves rigorous objectivity, its treatment of intelligent design shows a great deal of bias.
