quote: If you think that the fact that you said all function is lost is sufficient to prove that some function remains you have great faith in your ability to get things wrong.
quote: We're not discussing that at all, because that was accepted long ago. Instead we go round and round in circles with you switching between asserting that all function was lost and then trying to act as if you never said it.
quote: It certainly does matter. Since the only "50 proteins" figure we have is the number of different proteins in the E coli flagellum - which is made up of a good many more than 50 protein molecules using that figure implied distinct proteins. But OK, why would 1,000,000 units of 50 distinct proteins be significantly more improbable than 1 of each ?
quote: Given that the "complexity" we are talking about is a measure of improbability and not closely related to the normal usage then the scare quote are entirely justified.
quote: Then it's a pity that Dembski did no such thing.
quote: No, they don't. At least not if they want the result that they get to be anything more than a rough estimate. For things like dice and coins we use a uniform distribution - but that's because of knowledge, not ignorance. (And even there we acknowledge that there might be subtle biases in the real objects).
quote: In this case it means an idea that is often close to being right (but can be drastically wrong).
quote: Message 1056.
quote: In fact you did say that and attempted to misuse Sanford's definition to back up your claim.
quote: Please show that the figures used in the runs which lead to mutational meltdowns in large populations used figures derived from a real population.
quote: WHich of course means that the issue is not the loss of all genetic information, but just sufficient to disrupt one or more vital functions. Therefore the absolute measure of genetic information is not relevant (the more so because many of the "vital functions" will be "vital" because other aspects of the animal require them - the simpler the life form, the less it has to go wrong).
[quote]
In reality it does just that. Like I said. The probability is to small. Simple RNA chains won't find any new functions. And even if they did, they wouldn't be beneficial enough to actually outperform other and take over the population.
quote: You are also refusing to do the very same thing. But I am happy to let my argument stand unrefuted.
quote: If Sanford really claimed that population genetics really required all those assumptions to work at all then Sanford doesn't know what he is talking about.
quote: 1) is not strictly true since the chromosomes are broken up by recombination. Genes that are very close will tend to stick together but that is all. And even if this were not the case, then the most you could do is to take a chromosome as the unit of selection, not the genome. 2) is just illogical. The fact that genes interact doesn't mean that they can't be the unit of selection.
quote: In sexually reproducing species the genome does NOT get passed on in full. And in the long term natural selection will tend to favour the better alleles. "Hitchhiking" relies on the linkage remaining intact, which is not guaranteed even for adjacent genes - and you've got nothing else.
quote: How many bits of having more bits than the bound can a thing have ?
quote: Requiring exactly 50 proteins - that isn't in the specification. using the same proteins as in the E coli flagellum or variants of them - that isn't in the specification either.

quote: I am quite happy to leave it at the known function was lost, but we don't know if there were any other functions which remained or other functions gained. You, on the other hand will only leave it there if we hide the fact that you originally argued that ALL functions were lost.
quote: Because your reason was incorrect, but the closest you will get to admitting it is trying to conceal the fact that you said it.
quote: THe reason why it is more likely for dice is that the result of the throw is random. The production of proteins is not random - the structure is controlled by the gene. So getting multiple copies of the same protein is not at all like throwing dice.
quote: Of course what you say is quite silly. If we simply consider Dembski's idiosyncratic usage of complexity getting 500 heads in a row is a "complex" sequence. But in normal usage it would be seen as simple.
quote: I wouldn't like to speculate on Dembski's motives here.
quote:I didn't say that it was. quote: That's also wrong. Statistics are useful in dealing with approximations (e.g. calculation of error bars) but approximations are no better in statistics than in any other branch of maths.
quote: And you will notice that your wikipedia quote says nothing about uniform probability or the reasons for assuming it... In fact all it does is give the reasons for treating dice in terms of probabilities instead of exact predictions. Maybe you should have quoted the previous paragraph, but then that contains a reason FOR assuming that each number is equally likely.
quote: Dembski claims that his method produces a mathematical proof of design - so no, approximations aren't good enough,
quote: I don;t see why they should be expected to come here to back up your claims. And if they were supposed to show it in the paper all you have to do is to find the section where they did it.
quote: Well that's a confused mess. Nevertheless it seems clear that even an inviable cheetah embryo will have more genetic information than a perfectly viable RNA self-reproducing RNA strand - so obviously the absolute measure is not what we need.
quote: The same thing that you asked me to do. That is what "you are refusing to do the same thing" means.
quote: Just two problems with that. On is that inventing the gene gun doesn't require a knowledge of population genetics. The second is that it is quite possible that Sanford doesn;t agree with you.
quote: In other words "reality itself" does not say that the full genome is passed on by sexually reproducing species. Only half the genes are, and those are mixed by recombination. This is why we can't use the genome as the unit of selection - it doesn't persist long enough for the statistical effects to build up and dominate over noise. We need something that lasts, something that can spread through a population - and the full genome obviously isn't it.
quote: And that is simply an assumption. Oddly enough the "noise" didn't stop the alleles producing the melanic form of the peppered moth from spreading, once pollution turned the trees black.Natural selection can overcome noise. quote: And it also fails to happen every day. Recombination mixes things up.
quote: It's a simple question. Being CSI is having more bits of information than the bound. How is that measured in bits ? Why would you ever need more than one ?
quote: If it's not in the specification his calculation of the probability can't use it. And do you really think that log2-P(D*) is 50 proteins ?

quote: If you don't know why you did it, why should I know ? And it still doesn't change the fact that you DID argue for it, and that is why this bit off the discussion has gone on so long.
quote: This misses the point that we were talking about individual protein molecules, not genes. And in fact the version using 1,000,000 molecules need have no more genes than the version using 50 since you insist that each uses the same set of proteins.
quote: Even using Dembski's idiosyncrative definition of complexity the relation is not an inverse proportionality (the complexity is proportional to the logarithm of the inverse probability). Using a more normal understanding of complexity your assertion is even more laughable. But if you won't communicate unless I agree with your silly assertion, all I can say is goodbye and good riddance.

Oh, it seems that you can communicate after all...
quote: In other words your attempt to imply that you DIDN'T argue for it was a an attempt to deceive.
quote: Since we're talking only about individual protein molecules with the same structure, the only difference would be in the regulatory regions. Good luck arguing that the version that leads to 1,000,000 copies is going to be less probable than the version which leads to only 50.
quote: Dembski's definition is (to be generous to you) -log2 p where p is the probability. The ordinary definition is "complicated". Look up a dictionary if you really want to know more.
quote: I suppose that this is the sort of mathematics we can expect from someone who thinks that a probability can be "50 proteins". But no, there is no contradiction because -log n is NOT proportional to 1/n. (Two variables, a and b, are proportional if there is a constant c such that for all values a = c.b. )
quote: Well I don't agree because logarithms don't preserve proportionality.
quote: Firstly the entire statistics community does NOT accept Dembski's ideas. If they talk about complexity it is more likely to be Kolmogorov complexity which is a measure of compressibility of a sequence. Secondly the entire statistics community know what proportionality is and what a logarithm is and therefore know that you're wrong to say that p is inversely proportional to -log p. And thirdly the entire statistics community know that simply assigning equal probabilities to different outcomes without knowledge is NOT reliable.
quote: Except, of course, methodological naturalism doesn't say that supernatural explanations are false. It says that science isn't competent to investigate the supernatural. That's rather a big difference. (Your "criticism" also doesn't address the other pragmatic reason for using methodological naturalism - it has been hugely successful).
quote: The probability of getting the exact sequence changes. However if we consider Kolmogorov complexity the complexity depends not on the probability of the sequence, but the sequence itself. Sequences displaying a regular pattern are less complex than those which do not - so the definition of complexity we use is important. Even with Dembski's measure the relevant probability may not change - or it may even increase. That is because the relevant probability is the probability that the specification is met, not the probability of the exact sequence (as in Dembski's analysis of the Caputo case).

quote: You implied it, as is perfectly obvious.
quote: But they don't.
quote: Even if you do (and I have to say that I am far from certain that is true) it still doesn't matter because the sequence is dictated by the gene.
quote: Simple things can be improbable, too.
quote: I didn't. I denied that the relationship was inversely proportional - and your list proves me correct.
quote: Frequentists don't accept ANY probability based purely on a priori considerations. And nobody who understands probability theory thinks that you can get an accurate result just by assuming that the outcomes are equiprobable without information. It wouldn't even work for something as simple as the sum of two dice.
quote: Based on knowledge, not on ignorance. (And a fequentist would insist on rolling the die to be sure that it was fair).
quote: And you're wrong again. Methodological naturalism doesn't rule out intelligence at all. All it says is that science can't investigate the supernatural.
quote: However, abandoning a successful strategy to return to a failed alternative is hardly an improvement.
quote: The Caputo case was both. A protein is both, Your examples are both. They are not so distinct.
quote: Which is why I am correct to say that the length of the sequence does not dictate the complexity.

quote: That you hadn't tried to argue for loss of all function, instead of just the known function.
quote: And you are wrong as usual. The point is that the assembly of proteins is controlled by genes. So producing multiple copies of the same protein just requires using the same gene over and over again. Evolution doesn't enter into it.
quote: The sequence of the protein is dictated by the gene. Thus proteins do not assemble by chance.
quote: I defined proportional a couple of posts back. Two quantities a,b are proportional if there is a constant c, such that a = c.b for all values of b. THey are inversely proportional if a = c.1/b for all values of b.
quote: That is an inverse proportional relationship.
quote: Either we find out what the real probabilities are or we admit that we can't do the calculation for lack of the correct figures.
quote: In reality it's more to do with not knowing all the variables to an adequate precision - but also knowing that the die is a regular shape and that the mass should be evenly distributed. Even your quote points to the knowledge that the die is symmetrical,
quote: Then you are criticising a strawman. The methodological naturalism of science only ignores the supernatural. Intelligence, whether animal, human or hypothetical extraterrestrial species is included within the natural.
quote: I suppose that there are still people who attribute lightning, disease or earthquakes to supernatural beings, but these beliefs contribute nothing to our scientific understanding.
quote: In fact I know that the multiverse is entirely within nature and that scientific proposals for the cause of the Big Bang are likewise natural.
quote: So the fact that you didn't calculate the Kolmogorov complexity means that they are NOT sequences ? What a strange idea.
quote: Nevertheless the relevant probability is not dictated by the length of the sequence.

quote: What is true ? Are you now trying to assert that you did NOT argue for the loss of all function ?
quote: You said that they weren't different proteins. That is why I have to point out that more copies of the same protein isn't that unlikely.
quote: Since DNA replication was preceded by RNA replication we cannot say that the assembly of any protein was by chance. You are treading on unknown ground when you make that claim.
quote: I would say that y is proportional to the logartihm of x
quote: It's an inverse logarithmic relation.
quote: No, I don't want to stop science in it's tracks. The progress of science does mnot depend on making wild guesses that happen to be convenient to ID proponents Also your long paragraph is very, very silly. We conclude from induction that the probability of the sun rising tomorrow is very, very high. We do not conclude that it is just as likely not to rise or to perform odd manouevres as you suggest, There is no similar body of evidence validating the use of uniform probabilities - a method recognised as unsound by statisticians.
quote: No, I am CONTRADICTING the point by poiting out that the choice of uniform probability in this case is supported by knowledge. If it were not, it would be unreliable.
quote: I have no idea what that is supposed to mean. However the fact is that inference to naturally existing intelligences is entirely permissable within methodological naturalism - which is based on the natural/supernatural dichotomy, not the natural/artificial dichotomy. Thus any assertion that methodological naturalism rules out intelligence is false and a strawman.
quote: No, our universe (which includes the Big Bang) is not regarded as necessarily all of nature.
quote: Which is completely by Kol irrelevant since they are sequences and have a Kolmogorov complexity whether it is calculated or not. And that complexity is not determined by the length of the sequence.
quote: Not really. Two different proteins would be more complex than two copies of the same protein - and very likely more complex than three or four. Certainly by Kolmogorov complexity - and Dembski's measure is even more sensitive to other factors.

quote: I don't know why you said it, but you did and even admitted to doing so, not so many posts ago. And by past form you will admit to saying it again and insist that it is correct next...
quote: Perhaps you can go back to my earlier posts where I discussed the point only to be cut off by your insistence that you were using the same proteins...
quote: The current scientific view is that RNA life preceded DNA life, and this view has been accpeted for some time now.
quote: I haven't changed my mind on the relationship between Dembski's complexity and probabiity.
quote: And it's got nothing to do with the point we are arguing.
quote: Except that we could base it on induction or on an understanding of the dynamics of the Earth and it's relation to the Sun. Rather than assigning equal probabilities to all possible outcomes we know that it is highly unlikely that the Earth will stop spinning unless a drastic and improbably event occurs (conservation of angular momentum tells us it can't "just happen").
quote: And the article omits to mention the important things that we do know, that justify assigning equal probabilities to the six faces of the die.
quote: Which is both false and irrelevant to the original claim that methodological naturalism did not consider intelligent causes. Forensics work uses methodological naturalism - it does not consider demons or miracles - but it certainly allows for human action.
quote: You said:
So by definition the multiverse and big bang are supernatural.
The "big bang" not"the cause of the Big Bang. And you would still be wrong if you HAD said "the cause of the Big Bang". Your point 2 is also wrong. And I am not sure what the hell your point 3 is supposed to mean. Definitions aren't meant to be falsifiable.
quote: You don't use Kolmogorov complexity for probability because it isn't a probability. But then I suppose I shouldn't expect somebody who thinks that "50 proteins" is a probability to understand that. The point is that Kolmogorov complexity is a measure of complexity. And one which is rather better than Dembski's odd definition - and more accepted in the statistics community.

quote: The correct answer would be that we can't tell if it would lose all functionality or not.
quote: It was important enough to you when you insisted on it.
quote: Not necessarily. When dealing with identical units it doesn't matter which one goes into which slot.
quote: That is entirely the wrong way around. You can't use your guesses about information to argue the probability.
quote: RNA life doesn't need proteins at all. Therefore the synthesis and use of proteins is likely the product of evolution, based on the chemical properties of existing RNA rather than pure chance. Thus your claim that a protein "must" have formed by pure chance is refuted. That's how it helps me.
quote: You actually suggest that the fact that you have proven that my position was correct and your position wrong is a reason why I shoulod change MY mind ? I suppose this explains why so much of what you say is wrong.
quote: The question is, of course, about the reasons why we assign uniform probability. Something that goes completely unmentioned in either case. In case 2 we DO know the mechanics underlying the movement (the rotation of the Earth) we understand how this may be changed (and that it does change my small amounts over time) and that it is difficult to change to a significant degree. And if you don't know that muich then you had better retake high school physics.
quote: Since the Sun has very little to do with the Earth's rotation and we don't exactly need to know a lot about that to realise that significantly affecting it is a massive task (conservation of angular momentum plus decent estimates of the Earth's shape, diameter and mass will do) then your point is daft. Especially when it completely ignores the point you are supposedly discussing - there is no mention of uniform probability in it at all.
quote: The same as WHAT ? Non-uniiform motion ?
quote: And what we know about the dice justifies the use of uniform probabilities. Not ignorance.
quote: No, you said:
I said materialism rules out intelligence.
quote: Your question in 1) is unanswerable since we do not even know if our universe is all there is or if it is embedded in a larger naturak reality. Your point 2) is wrong because the multiverse is considered part of nature. The only difference between it and our universe is that the study must rest on theoretical study since it is not directly accessible (i.e. it IS "governed by natural law" and therefore natural). 3) Claiming that there may be more to nature does not entail that everything is natural. Your assertion is simply illogical and fallacious.
quote: No, I fully understand that that is Dembski's measure of complexity. What you fail to grasp is that it does not even agree with your intuitive ideas of complexity - let alone more widely accepted measures like Kolmogorov complexity.

At this point it becomes clear that you aren't worth talking to. The discussion has gone on so long and become so repetitive that I would be surprised if anyone else was still reading or if they would learn anything that had not already been covered.
The idea that you have to make a false claim, try to pretend that you hadn't said it and then try to pretend that you didn't say that you didn't say it over and over again round and round in circles is bad enough. But this piece of lunacy proves that you are a hopeless case:
WRONG! Totally wrong. This is precisely what we DO NOT know. We do not precisely know how the Sun is moving. As I said, we ASSUME it's going around the Earth once a day. But we could be wrong. Tommorow it could do a 360 loop at 12 o'clock in the noon and than continue as if nothing happened. We simply ASSUME it's not going to do that because it NEVER has before. So there is no REASON (as in PRINCIPLE OF INSUFFICIENT REASON) to think it will. You see, it's even in the name principle. The Principle of insufficient REASON. Since we have no reason to think a certain object is going to do, we assume it's going to continue doing what it has been doing all along. The the idea that we know how the Sun moves exactly is just too laughable. Hey, Newton's gravity is not a fact, it's a model. It explains the movement of the Sun pretty good. But it later on got improved by Einstein's Relativity, because it showed it's flaws. And Relativty has it's flaws too. So no, we do not know the true mechanism and ture motion of the Sun.
The sun does NOT go around the Earth. The apparent motion of the sun is due to the Earth rotating on it's axis. If you don't know that much then there's little I can say. As I said, we know that it would take a massive force to significantly change the rotation of the Earth and there is no likelihood at all that "it could do a 360 loop at 12 o'clock in the noon and than continue as if nothing happened." We don't even need to invoke gravity - conservation of angular momentum is rather more important ! Relativistic considerations aren't significant. either We know that Newtonian mechanics is an extremely reliable model for the masses and speeds involved. Edited by PaulK, : No reason given.

Sure Dembski proposes that. But nobody has ever used Dembski's method to detect design in living things - his method is so hopelessly impractical that even Dembski himself can't apply it correctly.
