Lol! Mormons say the same thing to me. I find it fascinating that only the religious take this tactic however. I can say of Bayes Theorem, in parallel with Richard Dawkins statement of science - "it works... bitches."

Philo:
The irony is Ehrman uses Bayes in every book he writes, and is ignorant of that fact. If he is putting some information out as being more valid than something else, he is using Bayes probability. He uses evidence, background knowledge of the Gospels, Jesus, etc., and he just hasn't formalized the math. We ALL use Bayes all the time.

Richard:
So the use of Bayesianism is not as innovative as you think it is. You remind me of the saying that to some one who has a hammer, everything looks like a nail.


Being innovative is not the point of Bayes Theorem or it's use. It actually is used to help us justify when we have enough evidence and probability to believe a claim, or else to disbelieve a claim when the evidence we have doesn't have as much oomph as a contrary claim on the same evidence. Innovative is an irrelevancy.

And Bayes Theorem can account for that "privileged" information you claim to have as well. Everyone of us have knowledge which others don't. That's part of our background knowledge as well. Bayes can account for this, as we use it realistically.

Philo,

I'm going to try another approach. I hope I am not coming across as attacking and it's putting you on the defensive. The reason I asked you about if you had read Schama earlier is because it illustrates that everything even nuanced and complex historical constructions are laden with ultimately contestable, assailable, circular, disputable building blocks. Take what you just said to Huckleberry earlier:

Huckleberry said:
I am curious as to what clear examples of Christian writing can be found exist prior to the 20th century which describe a Jesus dying in the celestial realms as a divine figure come to us in a ritualistic portrayal .

You responded:
The Ascension of Isaiah fits the bill of your question amigo.....

Now I'm not attacking here, let's have a discussion. That is a bit optimistic compadre. First, the dating that Carrier's framework requires (the same as the Gospel of Mark) is contestable and in dispute, see Robert G. Hall, "The Ascension of Isaiah: Community Situation, Date, and Place in Early Christianity," JBL 109 (1990), 289-306. Hall dates the Ascension to late 1st century/early 2nd century and evidences that dating by the contents of the Ascension demonstrating later reflection on debates found that were already present in the Gospel of John and in Revelation. That is strong stuff and incompatible with Carrier's framework, in fact would falsify it outright. It certainly has to be taken seriously. We can't say with any definitive percentage to plug into a Bayesian equation what date is correct, that's history - full of several consistent constructions that any one of which "could" be true. Carrier would argue his is because it fits in his greater framework of mythicism. But,

Second, there exist extensive journal articles that describe The Ascension in completely compatible terms with Docetism. Scholars have fit the Ascension very strongly with a Docetic view of Jesus and these Docetic views are found much more frequently in other literature not compatible with mythicism. Given the Ascension is the only possibility for the mythicist position the fact that it fits with a scholarly view quite compatible with plural Docetic writings and Docetism in general this leans us by a proper weighing against the mythicist position, because otherwise the mythicist position has this one lone wolf to support itself with when that wolf can be placed right in the pack with Docetic understanding. The best carrier could hope for in this situation is 50/50 which would be as charitable as possible towards the mythicist position. But, that just leaves us in the same place that you criticize the traditional scholarship with, we don't know for sure.

So, Carrier's interpretation could be right, could be. But by Carrier's own position his burden requires more than could be. To say as you do that it is a clear example of the mythicist position is just incorrect. It is an interpretation that has to conform and do so within a very disputable, contestable historical landscape. This is what is frustrating about your almost religious zeal and insistence that Bayesian reasoning is a cure. These very hard won views of traditional scholarship can be contested but Bayes reasoning doesn't change the fact that all is contestable and assailable. Just balance your reading with other positions for a couple months and you will begin to see this. Your falling for Carrier can build a consistent historical edifice with the same thing as that means it is true. You have to compare and contrast that edifice with other constructions and edifices and weigh the whole with the best explanation. Perception is the ultimate reality Philo, but that doesn't make it the ultimate truth. That remains in realm of alll is contestable. Welcome to the secular world.

Yes, but of course.... we have to deal with this kind of stuff all the time in historical studies. There is very precious little, so far as I can tell, that is not disputed in some way or another.

Take what you just said to Huckleberry earlier:

Huckleberry said:

Yep, so far.


Now I'm not attacking here, let's have a discussion.


But of course. All of this is discussion and learning. I see no attacks yet in this entire thread. I hope I am not seen as attacking anyone either.


That is a bit optimistic compadre. First, the dating that Carrier's framework requires (the same as the Gospel of Mark) is contestable and in dispute, see Robert G. Hall, "The Ascension of Isaiah: Community Situation, Date, and Place in Early Christianity," JBL 109 (1990), 289-306. Hall dates the Ascension to late 1st century/early 2nd century and evidences that dating by the contents of the Ascension demonstrating later reflection on debates found that were already present in the Gospel of John and in Revelation. That is strong stuff and incompatible with Carrier's framework, in fact would falsify it outright. It certainly has to be taken seriously. We can't say with any definitive percentage to plug into a Bayesian equation what date is correct, that's history - full of several consistent constructions that any one of which "could" be true. Carrier would argue his is because it fits in his greater framework of mythicism. But,


Agreed entirely. Dating is always notoriously difficult as witness the writings in the New Testament! :smile:

Second, there exist extensive journal articles that describe The Ascension in completely compatible terms with Docetism.


Well sure. That doesn't automatically follow however we are dealing with an either/or. It is entirely compatible with mythicist interpretations as well. There is nothing saying there can't be both. In fact, there is a lot of this kind of interpretations and evidences that show sometimes several different theories are compatible, even though they contradict, so this is good to note, and recognize it is part of our background knowledge. Most excellent.

Scholars have fit the Ascension very strongly with a Docetic view of Jesus and these Docetic views are found much more frequently in other literature not compatible with mythicism.


That can very well be, sure. But it is still also compatible with the mythicist interpretation even stronger when it is coupled with Hebrews as Carrier, Price, and others have shown. Again, we aren't in an either/or world. There were numerous contradictory as well as complentary views of dying gods in antiquity, some, as in the Ascension, completely living, dying, and resurrecting in the sky, in space, above the firmament, never getting to earth. Others were purely earth bound. We have gnostics views, the mythicist ideas, and later historicists, doceticists, etc. There were truly many dozens of different view as Carrier so properly noted as well.


Given the Ascension is the only possibility for the mythicist position the fact that it fits with a scholarly view quite compatible with plural Docetic writings and Docetism in general this leans us by a proper weighing against the mythicist position, because otherwise the mythicist position has this one lone wolf to support itself with when that wolf can be placed right in the pack with Docetic understanding.


That is one possible interpretation, yes. But again, this is not the only piece of evidence as Doherty has clearly shown in his book "The Jesus Puzzle," and which Carrier extended up into even the Dead Sea Scrolls 11Q Melchizedek which *also* shows a heavenly redeemer figure, yet different from the ascension or the book of Hebrews and also different from the gnostics as well! There are all kinds of views floating around in that day of various kinds of deities and theologies, world views, etc. We still may not be in possession of even the majority of them, those damn Christians destroyed most of it, so we wouldn't expect the evidence to have survived. All Bayes does for us is assess the evidence with the background, we arrive at no absolute certainty ever, just make sure we are approaching it honestly, fairly, openly, and working probabilities accurately.

The best carrier could hope for in this situation is 50/50 which would be as charitable as possible towards the mythicist position. But, that just leaves us in the same place that you criticize the traditional scholarship with, we don't know for sure.


Interesting, I certainly see it differently as there is more than the ascension in play with this theme, the Dead Sea Scrolls, gnostics, and New Testament materials also work in favor of the mythicist views, among others. 50/50 says we don't know, but our background and evidence shows us we can make statements that the evidence is what we would expect, if not even better considering so much was so damningly destroyed than what we could hope for, so that definitely appears to me to up the probabilities. This is the entire point of having discussions and learning with others and seeing what their take and evidence is also. THIS is the kind of discussion those damn scholars OUGHT to be having!

So, Carrier's interpretation could be right, could be. But by Carrier's own position his burden requires more than could be.


Agreed, as he is also.


To say as you do that it is a clear example of the mythicist position is just incorrect.


Not at all. It clearly is a mythicist piece of evidence, but that wouldn't exclude it being a gnostic piece of evidence also. It's not an either/or yet, or may never be, so fa as I can tell.

It is an interpretation that has to conform and do so within a very disputable, contestable historical landscape.


As is everything else in this field, yes indeed!


This is what is frustrating about your almost religious zeal and insistence that Bayesian reasoning is a cure.


Whoa. I have never said it is the cure, I have said it keeps us honest by exposing our assumptions so we can correctly reason about how much we can be warranted in believing a claim against other claims. Bayes Theorem is a method, it is not evidence in and of itself.


These very hard won views of traditional scholarship can be contested but Bayes reasoning doesn't change the fact that all is contestable and assailable.


Entirely agreed. It is precisely the reason that everything is contested and uncertain that we have no choice to make certain we are dealing with all our assumptions, all the evidence, every interpretation, etc., for its probability, and then discussing it with all others interested and working through the ins and outs of why one sees it one way and another sees it another. This is most excellent what you are doing here with this subject. It is too bad the professionals won't do it this way.

Just balance your reading with other positions for a couple months and you will begin to see this.


I have been attempting to do this for the last few years actually. I haven't found anyone willing to discuss it intelligently until you came along. This is terrific!

Your falling for Carrier can build a consistent historical edifice with the same thing as that means it is true.


No. Bayes cannot ascertain what is true, only what may be more probably right based on the knowledge and evidence, conditionally! And that only in light of other claims and how they fit or don't fit with the same evidence also. But we must compare, we must test, we must assess, interpret and learn all we can in the process so we help eliminate subjectivity and confirmation bias. This can take years, if not a lifetime. It is not a quickie apologetic hey look! The evidence fits, I'm right, you're wrong! Nothing like that at all.

You have to compare and contrast that edifice with other constructions and edifices and weigh the whole with the best explanation.


I am! It is the professionals who refuse to do this but insist on continuing using their fatally flawed historicity criteria instead. THEY need to begin having this very kind of discussion we are in order for real comparison and progress to be made. They refuse to consider using Bayes Theorem with its contention that everything in BOTH the historicist and mythicist views needs to be carefully weighed. They have dismissed the mythicist view prematurely. That is precisely why Carrier wrote his books and blogs. NOW we must read everything there also. And then discuss, compare, weigh, and calculate.

Perception is the ultimate reality Philo, but that doesn't make it the ultimate truth. That remains in realm of alll is contestable. Welcome to the secular world.

Bayes theorem has never showed it to be otherwise. Historicists are the ones who imagine and pretend they already have the ultimate truth. Just read Ehrman's lousy attempt on the historical Jesus and his ridiculous amateur wrangling against the mythicists!

I simply must commend you on getting on with this discussion in this manner! FINALLY we have a foothold we can make progress with! This is fantastic!

Best to you and yours,

That's just not true PS ( missing your posts on Facebook so seeing you post here is a good reason to stick around).
I can only say that in my experience historicists neither imagine or pretend they have the ultimate truth when it comes to the existence of Jesus. Hard work and years of trowling through sources have gone into drawing their tentative conclusions.

I agree that some even many in the field of Jesus scholarship have prior theological beliefs that may influence their writings. I see that particularly around the *resurrection* debate.

You'll get someone like Ehrman (or even Tabor) who will rightfully point out that resurrection is a faith issue, not a historical one. In terms of historical probability dead people don't walk out of tombs. So the next step is to provide rational explanations for why people may have believed that he did. The field already does that, and I don't see how using Bayes theorem can provide any more insight than the years of delving into sources can do. It's hard work and it takes years to even begin to get a cursory knowledge of the field.

Peer reviewed papers are there (not that it is a perfect process) because scholars should rightfully critique each others research and views. Scholars should state their bias and assumptions clearly and articles should be read in that light.

I am surprised you criticise Ehrman because his knowledge of the field of christian origins is far, far superior to Carrier's. And that's my main issue with Carrier, he isn't a specialist in any sense in this particular field. His writings and talks (I have watched a few) reveal him to be arrogant, rude, condescending with his assumptions full of naïveté and error.

BT may be great for other areas of study but I just don't see how it can be used productively within the field. There is no magic pill and BT doesn't represent one.

Philo Sofee , thank you for providing an example to consider, Ascension of Isaiah . I went hunting. Perhaps there are more versions. The one I found was pretty Catholic (it could possibly be read as Docetic as Mikwut noted)
///
". For Beliar was in great wrath against Isaiah by reason of the vision, and because of the exposure wherewith he had exposed Sammael, and because through him the going forth of the Beloved from the seventh heaven had been made known, and His transformation and His descent and the likeness into which He should be transformed (that is) the likeness of man, and the persecution wherewith he should be persecuted, and the torturers wherewith the children of Israel should torture Him, and the coming of His twelve disciples, and the teaching, and that He should before the sabbath be crucified upon the tree, and should be crucified together with wicked men, and that He should be buried in the sepulchre,"

As I assess this thread, there are likely four categories of postings
1) Philo Sofee (and perhaps 1 or 2 others) that think that Bayes Theorem, as an approach to history, would bring a bit more disciplined approach to the craft of historicity, as Richard Carrier argues for, and would call for each historian approaching a topic to weigh the probabilities of each different claim on a topic, in light of all the available evidence in an effort to identify the relative probability merits of the claims.
2) There are several posters in this thread that eschew the suggestion that historians' output would be of any better quality if Bayes Theorem being applied, preferring the traditional criteria approach and peer review only.
3) A bit less enthusiastic 'middle ground'--Bayes Theorem would bring some more rigor to the historian's craft, though would not, as Philo Sofee readily admits, yield the same resulting conclusion on which claim is more probable from the application of Bayes Theorem by two or more historians to the same question. If I recall correctly, Analytics, a life actuary who by training and daily in his occupation deals with mathematics probabilities from broad based demographic date, who sees value to the extra rigor that Bayes Theorem would bring to the discipline of historicity while acknowledging that much depends on the a priori assumptions and initial assignment of percentages to each claim that different practitioners would bring and thereby affect his or her result from applying Bayes Theorem to each different claim in light of all the available evidence on the topic
4) Others who seem to be offended by Carrier having dared to try to apply Bayes Theorem to the question of the historicity of Jesus and considering the mythicist Jesus claim along side the historicity one in an overall process of considering all claims in light of the available evidences.

mikwut has mentioned the adverse witness rule, and exampled it on the Jesus historicity question from writings of Jews at the time of the alleged Jesus, who would be adverse to the claimed messianic status of Jesus. But in my understanding of reading this thread, Philo Sofee has not claimed that to be irrelevant evidence (though Carrier might have, I don't know). Philo Sofee's point is that one should weigh all the evidence on the topic, and compare each claim, including mythicism, in evaluating the claim such as historicity, and then those that have done likewise are in a better position to discuss and debate their different results and perhaps narrow the gaps between the disparate claims more as a result of so applying Bayes Theorem--not that all will, as a result of applying Bayes Theorem be expected to achieve the exact same results.

I am largely in sympathy with you on this. But it's based more on assumption than probability.


I agree that some even many in the field of Jesus scholarship have prior theological beliefs that may influence their writings. I see that particularly around the *resurrection* debate.


No kidding right?! :surprised: Well, and I mean, it's for every theological theme ever taken up as far as that goes.

You'll get someone like Ehrman (or even Tabor) who will rightfully point out that resurrection is a faith issue, not a historical one. In terms of historical probability dead people don't walk out of tombs. So the next step is to provide rational explanations for why people may have believed that he did. The field already does that, and I don't see how using Bayes theorem can provide any more insight than the years of delving into sources can do. It's hard work and it takes years to even begin to get a cursory knowledge of the field.


Because ALL of our background knowledge shows us that these things simply have never happened and so the probability is extremely low it happened in this case. The claim then is people believed because they thought it happened historically. Or, people believed because it was invented as a religious worldview in light of what they themselves already had as part of their world knowledge view of dying and resurrecting mythological figures. This never happened to an actual historical person. The probability that it did in this oe case because it's our Jesus is extremely low on that consideration alone. And THAT is one reason why they hate doing the probability. Everyone feels better if Jesus existed, but that is assumed all the way through. Bayes helps us test all assumptions, even the most entrenched ones. Einstein did that with Newton and we are all the better for it. The Quantum physicists have continued doing it with Einstein, and we are even all the more better. Our assumptions are not knowledge in any field.

Peer reviewed papers are there (not that it is a perfect process) because scholars should rightfully critique each others research and views. Scholars should state their bias and assumptions clearly and articles should be read in that light.


So why the vehemence against putting Bayes Theorem to the assumptions they hold? THeir bias prevents them it appears to me. I could be wrong on that, but they'll have to refute this with actually putting Bayes Theorem to the use and show why Carrier's calculations are wrong, and why theirs are correct, NOT by ignoring the evidence that is there, but by using it ALL. This they have not done, but flippantly dismiss it out of hand.

I am surprised you criticise Ehrman because his knowledge of the field of christian origins is far, far superior to Carrier's. And that's my main issue with Carrier, he isn't a specialist in any sense in this particular field. His writings and talks (I have watched a few) reveal him to be arrogant, rude, condescending with his assumptions full of naïveté and error.


In criticizing a scholar, it is not to be assumed one has refuted and dismisses their materials. Ehrman is a very good scholar, but that doesn't mean he is always correct. Allison is a better scholar than Ehrman if all we go on is time in the field. Give it 20 more years, Carrier will have that experience as we all will, one has to start somewhere and somewhen. Crossan is one of the premieres in the field, but that hardly means everything he writes is accurate, realistic, and acceptable, right?

BT may be great for other areas of study but I just don't see how it can be used productively within the field. There is no magic pill and BT doesn't represent one.
[/quote]

I see it differently, and am in the process of writing up some materials using Ehrman's own claims as a basis just to demonstrate. I am doing the same with Nibley and other LDS writers as well. Ehrman was the one scholar, incidentally, that helped nudge me into an acknowledgment that my apologetic biases were being hidden by myself. I COULD NOT see I had the problem. Bayes brought this out for me personally. That's it's job. It corrects our own myopia, it's why I am using it. I now see the biases in apolgetics, including the apologetics of historical Jesus scholarship. It's everywhere. In time this will come out.
