No. Please do the world the courtesy of reading my lengthy post above and responding to what I've said is the real reason you're dragging your feet.

Do not simply keep trying to reset the argument. You don't understand consilience and you don't understand Bayes. This has been amply demonstrated to you over the past month. Your assiduous refusal to discuss the details of your misuse of these important concept simply reinforces my appraisal of your method and intent. My assessment grows more valid the longer you dodge your critics.

1) If we could show that the stains on the shroud were, in fact, blood, we would have a little bit of evidence that the shroud is authentic. That would be true because the likelihood of the stains being blood is greater if the shroud is authentic than if the shroud is not authentic.

No. You're trying to reset the argument back to where it was a month ago.

Your estimates of likelihood are simply made up out of thin air. Yes, here too. That very fact was what Hugh was trying to get you to see by bringing up the limestone. But instead of considering what he was trying to tell you about cause and effect cutting both ways, you brushed him aside, took his claim for exactly what it wasn't, and ran with it uselessly for a month.

As everyone (including your ally) has painstakingly explained, if someone wanted to make stains that looked like blood -- for whatever reason -- there's no shortage of blood anywhere in history, for anyone to use to do that. As we have explained to you, logically your claim commits the fallacy of the affirmed consequent, the first step in a circular argument. This isn't any different than where we stood a month ago, so it's just yet another reset of an argument that failed irretrievably a month ago. Your argument fails because it is a syllogism of non-validating form. No amount of research or tap-dancing can possibly fix that.

I have explained to you several times the principle of consilience. It requires lines of evidence to be developed in isolation, without regard to each other and without regard to some overall proposition toward which you're trying to induce. You flagrantly break both necessary parts. Your development of the blood evidence expressly invokes the overall conclusion of authenticity. Thus, as has been explained to you several times, you cannot make a case for consilience based on the line of reasoning you've developed.

And Bayes does not help you. As so many have done before you, you're simply misusing it intentionally in order to disguise that your argument is circular. I have explained this numerous times to you, in great detail. When you invoke Bayes with the preconceived notion that blood is more likely if the cloth is authentic, then all Bayes will do is reinforce that if you plug in the fact that the stains are blood.

And that's accepting for the sake of argument that the stains are blood, which you do not prove.

All your respondents prior to me have noted you are simply resetting the argument back to a state that has already been rebutted. You have not addressed the rebuttals. In fact, your inability to do so was why you went off on the limestone tangent.

Your debate strategy is ineffective, and has been so for four years because of your inability and unwillingness to accept correction when you are proven wrong, and to concede points you lose. I for one do not intend to let you keep spinning the hamster wheel. If you are serious about "effective debate," demonstrate your attention the summary below.

1. You have been told copiously exactly how your analysis logically unsound. Address it.
2. You have been told expressly why your argument cannot be consilient. Do not keep pretending it can be by this repetition.
3. You have been told in great detail several times how you are misusing Bayes. Do not simply keep begging the question and pretending Bayes will disguise it.
4. You have been asked to prove the stains are blood, as you claim. Do so immediately or admit you cannot.
5. You have been asked to present evidence in favor of authenticity. Do not continue to misunderstand what that proof entails.

Stop stalling and answer your critics.
 
Slowvehicle,

- It isn't the rarity of blood that makes actual bloodstains on the shroud be evidence for authenticity. It's that actual blood stains would be more likely on an authentic shroud than they would be on an inauthentic shroud.



"If I assume the shroud is authentic then it's more likely the stains are real blood and if the stains are real blood then it's more likely the shroud is authentic".

Pure genius.

Because his limestone argument was a complete failure.

The limestone argument was the tangential distraction from blood. Hugh tried to get Jabba to understand that the stains being bona fide blood would not prove authenticity because it's just too easy for there to be blood on the cloth by some means other than a bleeding Jesus. He brought up limestone as a similar non-determinant hoping that the obvious sources of non-Jesus limestone would illustrate the point to Jabba.

You saw what happened.

We're back to "one step at a time" on the blood, the same tiny steps he took a month ago and a year ago. Never any closure, never any concession -- just the same circular argument over and over.

Even if it was more likely than not that the authentic shroud would have blood on it, that would not mean that a cloth with blood on it is likely to be the authentic shroud.

But a cloth that's only 700 years old can't be an authentic shroud.

Or to make the point a bit more forcefully, let's say for the sake of argument that the stains can be conclusively identified as human blood. How does that not simply make it a 700-year old cloth with human blood? How do you go from that to "authentic burial shroud of Jesus?" Even a little bit?

You can't argue by consilience, because you expressly violated consilience in this case.

If you're trying to argue by preponderance, and say that if there's blood on it then it "tips the scales" toward authenticity, then you're still stuck. Because all you can ever prove with blood is that it's a cloth with blood on it, you can't say it tips the scales toward some specific cloth with a specific man's blood on it. That would be just you pasting your desired conclusion onto the evidence.

As Hugh was trying to explain, all this proves is that the evidence shows it's a 700-year-old cloth that also has blood on it. Blood cannot tip the scales, because blood is consistent with both sides of the scale. You cannot say that Bayes turns your consistent-only argument into a pro-authenticity argument, because you simply inject your disproven preconception into Bayes. Your deliberate misapplication of Bayes is your thumb quite visibly on the scale.

You apparently seem to think that real blood on the cloth somehow makes the radiocarbon dating less credible. It does not, and everyone sees this but you -- including the guy you tried to recruit as your ally.

Jabba,
- At a rough estimate, how many pieces of cloth with blood on them do you think there have ever been?
 
- Back to blood and the logic of consilience and Bayesian statistics -- one, or two, steps at a time.
- I claim that
1) If we could show that the stains on the shroud were, in fact, blood, we would have a little bit of evidence that the shroud is authentic. That would be true because the likelihood of the stains being blood is greater if the shroud is authentic than if the shroud is not authentic.

Why would blood matter when you can't date the cloth?

Jabba, please read this, because it is important. You may not like it, but it is important:

You are somewhat obsessed with "tipping the scales". However, not all kinds of evidence do that.

Dating evidence tips scales. For instance, the fact that the weaving of the shroud is more compatible with medieval weaving technique adds to the non-authentic side and detracts from the authentic side.

Obviously, the C14 dating sort of puts a brick in the non-authentic cup ....

Blood, on the other hand, is compatible with both sides, so it does not tip the scales. Nevertheless, for authenticy, you need blood: If the blood-stains are not blood, they show some kind of forgery, thus detracting from authenticy.

So, "non blood" tips the scale, and always towards non-authenticy.

Thus, you need blood, but blood does not detract from non-authenticy (because a forger might well have decided to use blood to make blood-stains).

Do you get it?

Hans

PS: When we talk about tipping scales, your tip should always reflect the service you feel you have received.
 
Blood/What difference does it make?

My Dear Mr. Savage:

Why, in your opinion, would it be more likely to find actual blood on a cloth that was supposedly "wrapped" around a corpse, than upon a cloth intended to artistically represent a crucified body?...
Slowvehicle,
- I haven't been able to find any painting of a crucifixion, or any pre-15th century painting at all, that used real blood. Consequently, finding real blood being used for blood stains on a 14th century painting should be extremely unexpected -- whereas, finding real blood stains on the authentic shroud of Jesus would be quite expected.

1) That's a logical fallacy called an Appeal to Ignorance. You not being able to find something could be because you aren't looking.

2) You're begging the question of authenticity again.

Blood has been used since Palaeolithic times in art.

One can only assume that not only did you not look very far, but you likely did not look at all.

But they weren't forgeries meant to fool people into thinking that they were real, or designed to be as realistic as possible.

Furthermore, just because you can't find another example of something is not proof that one instance doesn't exist. We could also argue that the lack of any similar image on a burial cloth makes it extremely unlikely that the shroud is authentic. Unless you want to claim that the shroud is miraculous

My Dear Mr. Savage:

Where, specifically, and in detail, did you look for "pre-15th Century paintings" using blood as a medium? Did you do a web search? Did you just ask around on sidonist sites? How did you conduct your search?

If you can find no example of a medieval cloth upon which actual blood was used to create an artisitc representation of blood, the incorrect color of the "blood" on the CIQ, its anomalous chemical compisition, and its ludicrously-depicted behavior, become even more of a problem for "authenticity". To be blunt: if the stains on the CIQ were comprised of blood from a human body, they would be a different color; they would be in different places, flowing, pooling, and clumping in different ways; and they would be of different chemical composition.

I remain dubiously yours, &ct.

You have yet to demonstrate there is any blood on the cloth, which, additionally, stubbornly remains only 700 years old.
 
I invoke the Rule of Yo!

Yo, Jabba!

You said upstream somewhere that you believe in magic.

Well la de da, Buffalo Bob. Everybody who knows you knows that. Why is your faith in magic so weak? Why don't you just run with it honestly, and cry "That's Jesus Himself's burial cloth! I see it with the eyes of faith!* All your science are belong to me!" or some such thing. That would be the honest reply, almost a respectable reply, and, here's a point you should note, an unanswerable reply.


That's right. If you'd just give over this weak havering about evidence and logic, nobody could even attempt any sort of rebuttal. "I believe!" defies intelligent commentary.

And you if anybody should understand defiance of intelligent commentary.









*Echoing an early Mormon, who testified to the real and present existence of the sheets of gold. "I will say only that I saw them with eyes of faith."

Slowvehicle,
- I did a few web searches. I used "painting of crucifixion using blood," "old painting using blood" and "using blood as paint."

Oh, well, case closed. :rolleyes:


Did you also try "radiocarbon dating of turin shroud"? Would you believe the result from that, too?
