Thanks switch89.

There is a tremendous difference between mathematical probability and subjective probability. Scientists use the former, while humanities scholars and laymen use the later.
But the field of ancient history admits scientific knowledge, analysis and testing technologies in assessing the ancient historical evidence. Furthermore, the field of ancient history is obliged to address physical evidence and represents an investigative model - there are Popperian constraints in its hypotheses.


Quote:
No Biblical historian has ever claimed that the historicity of Jesus, or that their belief in the historicity of Jesus was some sort of mathematical probability to begin with.

Biblical history is a subset of ancient history, but often the biblical historians lose sight of this fact. They may be called the "Insiders". The ancient historians may be called the "Outsiders". Anyone who wishes to talk about "Biblical History" must confront this simple reality.




Quote:
Claiming that the words "likely" or "probably" automatically infer mathematical probability is just plain false.
Underlying the (hypothetical) reconstruction of the ancient historical truth much of course is UNKNOWN - there is uncertainty with all the sources and all the evidence. Mathematical probablity can be of service to the field of ancient history, if used appropropriately. All fields are of service to the field of ancient history. It is just plain false that any should be prohibited.

IMO the idea is to apply Bayes theorem to ancient history, as an ancient historian, not as a "Biblical Historian". The origins of Christianity need to be studied OUTSIDE of the field of Biblical History, where they have been entombed for over 1600 years.

b. I have never read anything by Richard Carrier. Sorry for that.

Here is a brief discussion on Bayes Theorem that uses a graphical model and is related to medical testing (which you seem to have experience in) and therefore may assist in understanding what Carrier is attempting to do.



Quote:
The issue is whether or not Bayes' theorem is applicable to New Testament Studies.

I deny that it can be employed.

In the field of New Testament studies students, teachers and researchers can do what they please within certain hegemonic guidelines, and I would also deny that Bayes Theorem is applicable in such a field. However, and this is the main point IMO that bears repeating, the field of NT studies is of necessity a SUBSET of the field of ancient history.

A researcher in the field of NT studies is perhaps quite incapable of asking the question are the gospels fiction books. Such questions cannot be asked from within the box of NT studies or "Biblical Studies". Such questions can only be asked from outside the box of these fields. Outside the box of these fields - including these fields as subsets of itself - is the field of ancient history. Such questions may be asked outside the square, and answered.

I see Carrier as following this path.





Quote:
How would you feel if I informed the forum that I intended to apply the Heisenberg uncertainty principle to a study of Codex Sinaiticus....

Similar comments have already been made.

Consider Schrodinger's Cat Jesus.

Schrodinger's Cat Jesus


Jesus is in an ossuary box which investigators open and look into.

In some experiments some investigators see an HISTORICAL Jesus.

In other experiments other investigators see a MYTHICAL Jesus.

In yet other experiments other investigators see a FICTIONAL Jesus.

In further experiments others dont see anything at all.

In one experiment an investigator had a mystical experience.




What then is Schrodinger's Cat Jesus?


Is Jesus a QUANTUM BEING capable of changing states?

And can we sell this technology to a world market?











Quote:
In brief, if we cannot establish the conditional priors, we cannot employ Bayes' theorem.....


Some conditional priors can be established in the negative sense.

Can people walk on water?
Can people ascend through cloudbanks?
Can people lie through their teeth?


etc


Do not yet discount Bayes theorem for a certain amount of assistance in clarifying the hypotheses that are capable of being made with respect to the thousands and thousands of evidence items to be taken into account when reviewing the quest for the historical (or otherwise) Jesus with respect to the field of ancient history.

Carrier's blog post

Quote:
The promo copy prepared by Prometheus Books is really very good, and describes the book quite well. Basically, it aims at two particular objectives, and one broader objective: (1) to show why the methods used to study Jesus are illogical or inapplicable, and to replace them with a method that is neither; (2) to show why, once we use the correct method, every conclusion reached about Jesus so far is not defensible on any previously championed argument (requiring a total, field-wide do-over); and (3) to use these particular examples to make a general point about the entire field of history: that all valid historical argument is and must be Bayesian, and any methods or arguments that are not, are not logically valid or sound.

...

Since I am applying a mathematical theorem to the logic of historical argument, it’s often asked what my qualifications are in mathematics, since my primary field (my Ph.D.) is ancient intellectual history (philosophy, religion, and science), and my secondary field (self-taught but professionally published) is philosophy. The answer is, I had the book formally peer reviewed by a professor of mathematics, and consulted with a few other professors of mathematics during its development. I also, of course, researched the hell out of Bayes’ Theorem for this book. My more general qualifications are some 20 or so college semester credits in mathematics and mathematical and engineering sciences, and a career background in electronics and the history of science. But the peer review and consults were more important.

Another common question is how “out of the mainstream” my conclusions are. Actually, in this book, they are fully in the mainstream, with the exception of the groundbreaking idea of structuring the logic of historical argument on a foundation of Bayes’ Theorem, which is in many ways a natural progression of what’s already been going on in expanding the applications of that theorem. I’m just the first expert in the humanities to come along who also loves math and knows enough about it to introduce it there. But the rest of the book’s conclusions simply reaffirm what countless insider specialists have already been saying (and I name and cite plenty of them to prove that), and using Bayes’ Theorem to show why they’re right.

Testing two hypotheses:

h = “Jesus was a historical person mythicized” and
~h = “Jesus was a mythical person historicized.”



Quote:

John:

In your forthcoming book you’ll test between two hypotheses: h = “Jesus was a historical person mythicized” and ~h = “Jesus was a mythical person historicized.” Care to give us an advanced introduction to that book and/or where your research has led you so far based on Bayesian methodology?




Richard:

It’s no secret that I’ve come to the conclusion that ~h is more likely. And the more I’ve researched it, the more certain I am of that. I keep finding evidence supporting ~h; whereas evidence for h keeps disappearing the more I examine it. However, my conclusion does come close to the Granicus example above. I am not supremely certain. I just think it’s more likely than not. But this won’t be any comfort to Christians, since the next most probable hypothesis is that Jesus existed but we know essentially nothing about him. Which, incidentally, a lot of experts in the field are starting to agree with. It’s slowly becoming the consensus position. There are still hold outs, like Bart Ehrman, but I don’t think their position is going to survive in the long run. There are just too many cats out of the bag at this point. But what will be the fate of the next-step position, that there wasn’t even a Jesus at all? Time will tell. But someone needs to present the case properly before it can be conclusively accepted or refuted. No one has done that yet. My future book On the Historicity of Jesus Christ will. In the meantime Proving History does a good job already of showing why that currently growing consensus is correct; and it’s just one step from there to full mythicism.

Only if you are wedded to 'fuzzy' logic.

If a claim is 'likely' what the hell does that mean? How 'likely'? How 'probable'? Carrier is demanding that 'hand-waving' give way to a proper ordinal system of comparison, rather than vague descriptive verbiage.
Subjective probability. Look it up.

When a biblical historian says the word "probably", it is subjective probability being referred to. Certainly not mathematical probability. Subjective probability essentially means 'in my expert opinion'.

It is simply not possible to assign a mathematical probability to the historicity of Jesus. Ancient historians, and especially biblical historians, do guesswork. There was never any serious question about that.

I think you mean that biblical historians do not assign a precise mathematical probability to their guesses. But they can be quite sure (to the point of dogmatism) that something is more probable than not, and that everyone else must agree.

Yes, they can only assign subjective probabilities but people who disagree with them are similar to Holocaust deniers.

Thank you for your comment, aa5874, always appreciated.

Well, I could have erred, that's for sure!!!

Whether or not one isolates a single verse as a topic of investigation, is perhaps not quite as absolute, as you have indicated.

Prior to expressing that opinion, may I humbly inquire whether or not you have performed a search of any books which may have been written, precisely on only a single verse of the new testament?

I do not have, at the tip of my tongue, the title, but, I believe there is an entire book written about this particular verse, Mark 1:1. One verse.

However, whether or not, OTHER folks insist on reading many verses, or not, I myself, because of my own modest cranial capacity, restrict myself to but a single verse, for beyond that, I forget what I was just reading....

I would draw an analogy with music: I enjoy the simplicity of the American, minimalist composer Philip Glass, for example, Itaipu. I expect you would prefer more polyphonic melodies.

Apart from this banality, however, the example provided was intended only to serve as illustration of something which many of us face, in our own lives: cancer diagnosis.

To employ Bayes' theorem to offer an opinion about the probability of something, one needs to know some facts, i.e. some parameters which are undeniable. The radiological investigation is not a fact about the underlying pathology, but it is a method of suggesting with great confidence, how likely it is the person of interest has, or does not have, cancer. The confidence we have, in the radiological procedure is based upon thousands of investigations, over many decades. The method is imperfect, but has fairly good prognostic value.

When we turn to studies, not of cancer, but of ancient papyrus documents, we have no sure footing, no base upon which to support our weight, as we attempt to climb up a precarious scaffolding.

I gave the illustration of just a single verse, to show that even for this, relatively uncontroversial, and very short passage, there is a lack of agreement about what the text indicates.

We could not better identify which of the three versions represents the ORIGINAL ink flowing from the quill of "mark", if we examined dozens and dozens of other versions.

With cancer, the question ultimately is benignity or malignancy. With new testament studies, focused on the origins of Christianity, the question is one of authenticity.

Giving us scores and scores of other verses, doesn't convince anyone of the correct identification of the authentic, original version of Mark 1:1. It is also unhelpful to list thousands of manuscripts representing version A of Mark 1:1, and only ten copies of version B, and only two copies of version C. We still cannot conclude anything definitive about the authenticity of the three different versions, hence my skepticism of Carrier's approach. Bayes' theorem, to be demonstrated useful, requires CERTAINTY about something. What we have here is uncertainty, exclusively. We don't even know, for sure, what I.C. means, in the Codex Sinaiticus version of Mark 1:1. Does it mean Iesous Christus, or, does it mean Isis, or, as Stephan Huller professes, "yesh"? Was the original meaning, with Hebreic influence, purged, in the tiny handful of documents which we still have in our possession?

What will convince me that Bayes' theorem can be applied to new testament investigations, is not the text of a scholar, even one renowned, and as brilliant, as I am sure Carrier is, but rather, an example. I will go now, and read mountainman's link, which ought to explain the problem is some depth.

That position is a stalemate for the historicist/ahistoricist debate. For the ahistoricist/mythicists to avoid this stalemate they have to bring more to the table than simply the old arguments against the external historical sources. Once the historicists opt for a flesh and blood JC and ditch their failed efforts to provide historical evidence - the debate becomes a stalemate.

A way to avoid this stalemate is to shift focus away from Carrier's two JC hypotheses. The gospel JC figure is neither "a historical person mythicized" nor "a mythical person historicized". The gospel story is history mythicized. That's the road forward - history. Jewish history.

As far as I know we are making assessments of written statements of antiquity. We are not involved in any radiological investigations.

It is a most simple exercise that has been blown completely out-of proportion.

One can easily understand Plutarch's "Romulus" written c 70 CE but will declare that the versions of gMark are somehow incomprehensible.

gMark or any book of the Canon can be easily understood like Suetonius' Lives of the Twelve Caesars", Tacitus Histories, Philo's "On Embassy to Gaius" or Josephus' Wars of the Jews.

One does NOT understand those books by reading the first sentence.
