    Joe Felsenstein: I bake a lemon-meringue pie (*). It is delicious, but I am fairly sure that physics cannot give a detailed step-by-step explanation of what happened.
    Therefore … what? Have we refuted physics?
    * (You can tell I wrote this just before dinner …)

    Physics doesn’t know what a lemon-meringue pie is Joe.

    Physics doesn’t know why you baked a lemon-meringue pie.

    You would be correct that physics cannot give a detailed step-by-step explanation of what happened. Or why it happened.

    But why not?

    There’s nothing non-physical going on here, right?

    Everyone happened according to physical laws.

    And physical law is deterministic.

    I don’t claim expertise in anything. and knowledge of the sort you are referring to is completely irrelevant to the point.

    Well I’m sorry, cmm, but that bit of knowledge is key to your claims that evolution is insufficient to create such anatomy and physiology.

    For example when you claim evolution is insufficient to explain the origin of pulmonary circulation and four-chambered hearts I believe that it is prudent, as it pertains to vertebrates, what data is available on this subject.

    what could possibly have lead you to believe that I was claiming that evolution was insufficient to create such anatomy and physiology?

    For the record once again My claim is that evolution is not sufficient to explain particular targets not that it is insufficient to “create” anything .

    Again it is like pulling teeth.

    Why do I get the feeling that you folks feel that the world will collapse if the fundi is allowed to be right even once?

    Then given that data available for the development of pulmonary circulation (target in your mind) and the transition from a three-chambered heart to a four-chambered heart your claim that evolution is insufficient to produce this anatomy (target in your mind) is confusing at best.

    demonstrate that you are correct and there won’t be any teeth-pulling. regardless of anyones religious affiliations.

    No and that was never the intentwe just have proven that “physics” does not fully explain the pie.

    Is that what we have proven? It still sounds like you’re saying something different from what I would say — that we don’t know enough details to apply the physics well enough to explain all the details of the pie.

    Do you think this is a zero sum game? where the fundi must be defeated at all costs?

    No, I am happy if people can explore your argument. I am just trying to analogize your arguments about whether evolution can explain biological situations to an argument about whether physics can reasonably be expected to explain the pie in detail, in a situation where you and I would hopefully agree that, for the pie, a physical and chemical explanation is probably good enough.

    In order to explain my position after a roll you need to include more than just the algorithmic process of physical laws you need to to include the original positions and characteristics of all the matter and energy in the universe.

    Obviously? I do understand that you’ve made some clams that point to a clear lack of awareness of what data is available that directly addresses your claims of evolutions insufficiency to ‘achieve’ various ‘targets’ that you have fixed in your mind. My point is that such a failure in being aware of this data has left you in a precarious position to justify the veracity of your claims to the insufficiency of evolution to have reached the ‘targets’ you have outlined. Perhaps you might consider that your ignorance on the depth, and breadth, of the data that is available might have an impact on the claims you are making…….and not in a good way. Just a thought that maybe you can address in the future.

    On TSZ we are supposed to assume no “secret motive” behind what anyone is doing (regardless of whether you actually think there is or not). This also includes asusming that people aren’t assuming that YOU have a secret motive!

    Easier to say than do, but I’m putting this as a reminder.

    Try your best, guys, whoever you are, to make the working assumption that there are no ulterior motives behind anyone’s words. There are plenty of other places on the internet where you can articulate your suspicions in freedom!

    I don’t quite get your version of “explanation”. A stochastic process can explain an outcome without predicting it. Even with strict determinism, it is impossible to predict the course of complex processes.

    There are mini-controversies in biology over the relative contributions of drift vs selection, but this is orthogonal to the issue of determinism. Regardless, we cannot predict the effects of mutations. At the moment we can’t even predict the immediate phenotype, much less the long term effect in the context of the biosphere.

    It doesn’t seem simple logic to me.

    “Because his truck carried him there” is not a satisfying explanation for Buba’s trip to the Walmart.

    Perhaps. But “satisfying” doesn’t have much to do with simple logic. And what is satisfying varies from person to person and from circumstance to circumstance.

    fifthmonarchyman: A process that is not targeting a particular outcome can not be called upon to explain that particular outcome. This is just simple logic.

    I would say that not only is this not simple logic, it is simply wrong.

    So before we get into any higher math, I think we need to come to some uncommon understanding on this.

    It does not appear to be compatible with processes that are both deterministic and unpredictable.

    But I don’t believe in “holding back” or asking questions designed to win an argument by an “ah ha” at the end. I’m not trying to win an argument. I’m trying to reach an understanding.

    So I will lay out my position on biological inventiveness up front, so perhaps we can move on.

    I would say that the evolutionary landscape is the laws and properties described by chemistry. Chemical elements and chemical compounds have objective properties. When a pharmaceutical company is “targeting” an effect, they produce a huge batch of variations on a molecule type, and then test.

    It is worth noting that this is design, and it is worth noting that the process mimics what biologists understand as evolution. Make a bunch of variations and select those having desired properties. As far as I know, it is not possible to know the value of any particular molecule in advance.

    Let’s say that this process eventually leads to some useful and lucrative new medicine. Was the particular molecule a target? In what sense was it a target? What would we say if the final product has effects that were not conceived of prior to discovery? What if the useful and lucrative effect is serendipitous?

    Does the process explain the product, or not?

    There is a great deal we do not know.

    One of the things we do not know is how to design biology without using some process equivalent to evolution. Cut and try.

    I am not particularly interested in the philosophical question of determinism. If anyone can give me a definitive way of testing whether stochastic processes at the quantum level are truly random or are determined, please step forward.

    I do not think it matters in biology whether mutations are random or merely uncorrelated with usefulness. Lots and lots of mutations happen. Every human carries a hundred or so completely new mutations. Most of them will never be fixed in the human population.

    One might ask — if the correct path to a biological target is predetermined or front loaded — why the process looks stochastic and why there is so much blood and waste. (But this argument hasn’t been brought up on this thread, so perhaps it is out of place).

    fifthmonarchyman,

    I’m glad to see an ID proponent willing to make a positive argument for ID participating here. I’ve been swamped with work this week, so I’ve been unable to keep up with the discussion until now. Reading this thread in its entirety in one sitting has a few advantages, though. First, I feel like I’m at the beginning of a novel where the author is heavy handed with the foreshadowing. A recurring theme in your comments is:

    My fear was that folks have too much invested in not giving the interloping fundi even an inch of ground and so far it’s turning out that way

    Me too, It would help if getting a simple acknowledgement of that fact was not like pulling teeth. It’s almost like you guys are afraid to give even an inch.

    Do you think this is a zero sum game? where the fundi must be defeated at all costs?

    Why do I get the feeling that you folks feel that the world will collapse if the fundi is allowed to be right even once?

    From my reading, no one here is refusing to recognize when you are right. The problem, certainly for me, is that it’s not clear what you are claiming. I look forward to your upcoming post with your full argument. I hope you will keep Elizabeth’s comment in mind while you’re writing:

    Getting terminology agreed is extremely important — I’d say it is vital to prevent discussion getting bogged down. So much of the sound and fury of IDist versus non-IDist discussion, to my mind, arises from people meaning different things by different terms.

    Your definitions are essential to your argument. If your argument is to be understandable, your definitions must be clear and unambiguous. Given that, I urge you to provide operational definitions for all of your terms, including these I noted while reading the thread:

    – algorithmic process
    – integrated information
    – non-computibility (and explain why you consider this a “hallmark of design”)
    – unitary consciousness
    – target (remembering that evolution does not have targets)
    – explanation (being careful not to slip in teleology where no agent is demonstrated to exist)

    If “integrated information” is the same as that used in the “Is Consciousness Computable” paper, please add your own clarification as to why the math is applicable to whatever claim you are making.

    Importantly, based on previous discussion, if you use the word “information” alone or in any term, please provide worked out examples of how to calculate it according to your definition. The calculations must be reproducible by objective observers.

    Finally, you asked these questions early in the thread:

    Do I need to demonstrate that evolution is an algorithmic process?
    Do I need to explain how specifications and targets and integrated information are all the same thing?
    Do I need to show how Active Information is simply another way of thinking about CSI?
    Do I need to establish that Informational integration/Irreducible complexity is observer dependent or is this obvious?

    The answer to all of them is “Yes!” (assuming they are important to your argument.

    I am very interested to read your upcoming post. I’ve observed the ID movement for years and have never seen a positive argument for ID (or even a testable hypothesis). Please be the first.

    I think evilutionsts are pretty much agreed that evolution doesn’t have targets, so it seems critical that we address this up front.If it can’t be resolved, I don’t see how the discussion can progress. If “S” is not “S”, then CSI seems somewhat empty.

    I’ve noticed a bit of a shift in the definition of “target” at UD. In some of the Winston Ewert discussion, a “fitness function” was being described as a “target”.

    It is obviously true that in a GA, the designer of the GA designs the fitness function so that the virtual organisms tend to evolve to solve her problem.

    So there is a sense in which “a solution to her problem” is the target. And she knows in advance that her goal is “a solution to that problem”. What she doesn’t know is what the solution is.

    Nobody disputes that GAs have a “target” in the sense of having (at least sometimes) a problem they want their evolving population to solve.

    But that is not the “target” in the sense used by Dembski. The “target” is found by the evolutionary process, not by the designer – that’s why we use the things.

    And the equivalent, in nature, is therefore not a bacterial flagellum, for instance, but “some means of bacteria moving around in a viscous fluid”. Nobody has to design that “problem”. It’s right there “written in” to the resources and threats of the environment – the bacteria are in a viscous fluid, and if they stay put they will soon run out of food.

    One big problem with WEASEL (and I don’t blame Dawkins for this, though I blame him for other things) is that exceptionally, the problem and solution are identical. The problem is: find a string that matches “methinks it is like a weasel” and the solution is the string “methinks it is like a weasel”.

    It works, and it works by evolutionary means, but it’s a toy, and it conflates two items which don’t in practice coincide. You could know in advance what Weasel was after by inspecting the fitness function. But if you are after a circuit with a particular property, you have no clue what the solution is in advance, and the winning circuit might be totally unexpected. In fact, you may have to spend a lot of time figuring out why on earth it works!

    I was trying not to be intimidating because I’m genuinely interested in fifthmonarchyman’s argument. Whether it came across that way or not, I was attempting to share with him (gender presumed based on nym) the flaws I’ve seen in other such efforts. In my experience, ID proponents and other creationists seem to resist providing clear, operational definitions. I’d like to see a real discussion, not simply another creationist storming off in a huff because his arguments lack rigor.

    Which is why I have been trying to get clarification on just one element, that of “target” and of explanation for reaching same.

    I think I got that part, but “explaining” in a physically complete sense is an infinite regress.

    How did Bubba get to be conceived and born? How did his parents meet? How about his grandparents?

    Evolution does not provide a physically complete explanation back to the beginning of time.

    What it does do is describe a dynamic process of change in populations.

    I am not happy with this line of thinking.

    The presence of a target is an after the fact observation. Most bacteria get along without rotary flagella, so it isn’t a “problem” to be solved.

    Nor is the Weasel string a target to be found. That’s simply the wrong way of looking at what happens.

    Humans can look at the Weasel program and assert it is searching for a target, but that’s a personification. The uninterpreted process is that the population of strings shifts as a result of differential reproductive success.

    Similar programs can be written that have no specific target at all, but in which, the population drifts as a result of non-specific changes in reproductive success.

    Indeed, but if, in Ewert’s formulation, a “search” is a “probability distribution” then a “target” is one of the configurations in that probability distribution. The target is NOT the search method.

    If UD regulars want to move the case (as Ewert Dembski and Marks effectively do) from arguing that the target must have been designed (as in Dembski’s rejection-region argument) to the argument that the SEARCH must have been designed (“search for a search”) then UD regulars need to acknowledge that they are no longer claiming that the old TARGET had to be designed, but that the probability distribution on which it and its fellow configurations lies has been.

    And that is a quite different argument.

    Elizabeth: (“search for a search”)

    I would define ID as a search for a map that doesn’t show evolution as a feature.

    My standard way of describing an ID argument is that one starts with an abstraction (“search”, “information”, “target”), then reifies the abstraction and claims victory when evolution doesn’t work in the abstraction.

    ETA:

    Not aimed at anyone in particular. I think we all look for ways to support our view of how the world works.

    But, I think Behe is the only one in the ID movement who has had the courage to depict a specific before and after snapshot of a gene and say, “You shall not pass.”

    So far he has only sustained flesh wounds.

    DEM do not define a search as a probability distribution. This was covered extensively at UD before you left. It’s also been covered here at TSZ.

    As I have posted (here) in your own thread on Evolutionary Search, DEM do precisely define a “search” as a probability distribution of points in their search space Ω.

    Why are you saying to Elizabeth that this is not so?

    Mung is now denying what he accepted, interacting with me at UD. He quoted passages of DEM there, highlighting search. It’s hard to believe that he missed the opening of their second paragraph:

    In generalizing conservation of information, we first generalize what we mean by targeted search. The first three sections of this paper therefore develop a general approach to targeted search. The upshot of this approach is that any search may be represented as a probability distribution on the space being searched.

    I know the comment isn’t going to Guano. But you shouldn’t respond.

    Edit: Joe commented while I was composing. Here is Mung at UD, quoting Ewert’s ENV post:

    The use of the term “search” has led some to argue over whether or not Darwinian evolution can be considered a search. After all, Darwinian evolution is not a teleological process and does not search for a goal. However, all that we mean by search is a process that can be represented as a probability distribution. That means that all processes reducible to chance and necessity qualify as searches.

    Emphasis added by Mung, not me. His next move is to harp insubstantially on one word.

    Joe and Tom have responded, Mung, but I also point out to you: That is how Ewert has defined a search, in this context.

    Which has always been implicit in Dembski’s work, and was stated explicitly by Ewert.

    A probability distribution is always generated by a process. Dembski has argued that if p(T|H) i.e. the probability of the target given the hypothesised process, is small enough, we can reject that process as an explanation for the target. He also argues that even if for some evolutionary processes, p(T|H) is quite high, that process itself has low probability, given the probability distribution of all possible processes – hence “search for a search”.

    I’ve not recently interacted with anyone named Tom English at UD, Sad, really, that people hide behind a pseudonym.

    LOL! Says the guy who posts under the pseudonym “Mung”.

    IDiots are well known for their hypocrisy.

    Inconceivable! People using different pseudonyms on different web-sites!
