Gentleman Joe

Over on The New Oxonian, R. Joseph Hoffmann, leader of the Jesus Process©™® Triumvirate has deigned to comment on my post, “Proving This! — Hoffmann on Bayes’ Theorem.” As expected, his response is both cordial and understated. Ever the gentleman, he remains humble, even though Hoffmann’s massive and mighty brain threatens to burst through his shiny, pink forehead. At first I had considered answering him right there on his site. However, since I respectfully disagree with so much of what he has written, I have decided to create a new post here on Vridar instead.

I’ll quote chunks of Hoffmann’s words here, interspersed with my responses.  He’s reacting to a comment by a guy who goes by the screen name “Hajk.” Hoffmann begins:

Yes @Hajk: I was laughing politely when Vridar/Godfey[sic] made the bumble about “pure mathematics” in scare quotes; it reveals that he is a complete loser in anything related to mathematics, and when he goes on to complain that Bayes doesn’t “fear subjectivity it welcomes it” may as well toss in the towel as far as its probative force goes. Odd, someone conceding your points and then claiming victory.

Misunderstanding a theorem

Over on New Oxonian, Hoffmann is at it again. In “Proving What?” Joe is amused by the recent Bayes’ Theorem (BT) “fad,” championed by Richard Carrier. I’ll leave it to Richard to answer Joe more fully (and I have no doubt he will), but until he does we should address the most egregious errors in Hoffmann’s essay. He writes:

So far, you are thinking, this is the kind of thing you would use for weather, rocket launches, roulette tables and divorces since we tend to think of conditional probability as an event that has not happened but can be predicted to happen, or not happen, based on existing, verifiable occurrences.  How can it be useful in determining whether events  ”actually” transpired in the past, that is, when the sample field itself consists of what has already occurred (or not occurred) and when B is the probability of it having happened? Or how it can be useful in dealing with events claimed to be sui generis since the real world conditions would lack both precedence and context?

I must assume that Joe has reached his conclusion concerning what he deems to be the proper application of Bayes’ Theorem based on the narrow set of real-world cases with which he is familiar. He scoffs at Carrier’s “compensation” that would allow us to use BT in a historical setting:

Carrier thinks he is justified in this by making historical uncertainty (i.e., whether an event of the past actually happened) the same species of uncertainty as a condition that applies to the future.  To put it crudely: Not knowing whether something will happen can be treated in the same way as not knowing whether something has happened by jiggering the formula.

Different values yield different answers!

I’m not sure what’s more breathtaking: the lack of understanding Hoffmann demonstrates — a marvel of studied ignorance — or the sycophantic applause we find in the comments. Perhaps he’s getting dubious advice from his former student who’s studying “pure mathematics” (bright, shiny, and clean, no doubt) at Cambridge who told him:

Its application to any real world situation depends upon how precisely the parameters and values of our theoretical reconstruction of a real world approximate reality. At this stage, however, I find it difficult to see how the heavily feared ‘subjectivity’ can be avoided. Simply put, plug in different values into the theorem and you’ll get a different answer. How does one decide which value to plug in?

You don’t have to do very much research to discover that Bayes’ Theorem does not fear subjectivity; it welcomes it. Subjective probability is built into the process. And you say you’re not sure about what value to plug in for prior probability? Then guess! No, really, it’s OK. What’s that? You don’t even have a good guess? Then plug in 50% and proceed.

It’s Bayes’ casual embrace of uncertainty and subjectivity — its treatment of subjective prior probability (degree of belief) — that drives the frequentists crazy. However, the results speak for themselves.

And as far as getting different answers when you plug in different numbers, that’s a common feature in equations. Stick in a different mass value in F = ma, and — boom! — you get a different value for force. It’s like magic! Good grief. What do they teach at Cambridge these days?

The proper application of BT forces us to estimate the prior probabilities. It encourages us to quantify elements that we might not have even considered in the past. It takes into account our degree of belief about a subject. And it makes us apply mathematical rigor to topics we used to think could be understood only through intuition. Hence BT’s imposed discipline is extraordinarily useful, since we can now haggle over the inputs (that’s why they’re called variables) rather than argue over intuitive conclusions about plausibility — because truthfully, when a scholar writes something like “Nobody would ever make that up,” it’s nothing but an untested assertion.

Bayes’ Theorem ascendant

If you can possibly spare the time, please watch the video after the page break. In it, Sharon Bertsch McGrayne, author of The Theory That Would Not Die: How Bayes’ Rule Cracked the Enigma Code, Hunted Down Russian Submarines, and Emerged Triumphant from Two Centuries of Controversy recounts the story of how Bayes’ Theorem won the day. She tells us how BT is well suited for situations with extremely limited historical data or even no historical data — e.g., predicting the probability of the occurrence of an event that has never happened before.

Ehrman Confesses: Scholars Never Have Tried to Prove Jesus Existed

Creative Commons License

by Neil Godfrey

Thomas L. Thompson, Professor of Theology, National Endowment for the Humanities Fellow and editor of biblical studies journals, wrote in 2005 that historical Jesus scholars have always just assumed that Jesus existed:

Twentieth-century scholarship, with its faith in history, assumed a historical Jesus as its starting point. It shared Schweitzer’s personal dilemma: a choice between a Jesus who fits modern visions of Christianity and Mark’s failed prophet. But they always assumed there was a historical Jesus to describe. (p. 7, The Messiah Myth (2005) by Thomas L. Thompson)

Now Professor Bart Ehrman has said the same thing. He even says he believes he is the first scholar ever to set out a sustained argument to prove Jesus existed!

I realized when doing my research for the book that since New Testament scholars have never taken mythicists seriously, they have never seen a need to argue against their views, which means that even though experts in the study of the historical Jesus (and Christian origins, and classics, and ancient history, etc etc.) have known in the back of their minds all sorts of powerful reasons for simply assuming that Jesus existed, no one had ever tried to prove it. Odd as it may seem, no scholar of the New Testament has ever thought to put together a sustained argument that Jesus must have lived. To my knowledge, I was the first to try it, and it was a very interesting intellectual exercise. How do you prove that someone from 2000 years ago actually lived? I have to say, it was terrifically enlightening, engaging, and fun to think through all the issues and come up with all the arguments. I think really almost any New Testament scholar could have done it. But it ended up being lucky me. (Did Jesus Exist as Part One, accessed 14th May, 2012, my bolding and italics)

Can you imagine a biologist or paleontologist posting on a blog “no-one has ever tried to prove evolution”? Or a physicist saying “no-one has ever tried to prove the laws of physics”?

And note, further, the way Ehrman implies he went about this novel exercise of actually, for the first time in his life, trying to set out “a sustained argument” that Jesus existed. No references are made to historical methodologies. He simply sat down and thought it all up off the top of his erudite head. That he had never thought this through before, his neglect of historical methodology, even elementary logic, shows through when he writes some excruciatingly embarrassing pages in chapter two of his book Did Jesus Exist?

Putting James the Brother of the Lord to a Bayesian Test

I saw none of the other apostles, except James the brother of the Lord. — Galatians 1:19

On this verse some hang their strongest assurance that Jesus himself was an historical figure. Paul says he met James, the brother of the Lord (assumed to be Jesus), so that is absolute proof that Jesus existed. That sounds like a perfectly reasonable conclusion. So reasonable, in fact, that some quickly denounce as perverse cranks any who deny this “obvious meaning”.

But should historians be content with this? Is it being “hyper-sceptical” to question this explanation?

We need to keep in mind some fundamental principles of historical research and explanations from the professional historians themselves. Renowned conservative historian, Sir Geoffrey Elton, warns against deploying such simplistic methods as citing a single piece of evidence to make a case. In this instance, the case is about evidence for the historicity of Jesus.

Historical research does not consist, as beginners in particular often suppose, in the pursuit of some particular evidence that will answer a particular question (G.R. Elton, The Practice of History, p.88)

If that’s what historical research is not, Elton goes on to explain what it is:

it consists of an exhaustive, and exhausting, review of everything that may conceivably be germane to a given investigation. Properly observed, this principle provides a manifest and efficient safeguard against the dangers of personal selection of evidence. (p.88)

Since I am currently reading and reviewing Richard Carrier’s Proving History: Bayes’s Theorem and the Quest for the Historical Jesus I am taking time out in this post to see what happens if I test this “obvious” interpretation of Galatians 1:19 by means of Bayesian principles. Carrier argues that Bayes’ Theorem is nothing more than a mathematical presentation or demonstration of what goes on inside our heads when we are reasoning about any hypothesis correctly. So let’s try it out on the conclusions we draw from Galatians 1:19.

The way it works is like this. (But keep in mind I am a complete novice with Bayes’ theorem. I am trying to learn it by trying to explain what I think I understand so far.) I see a verse in Paul’s letters that appears to have a simple explanation. I think of myself as a geologist looking at strata in a rock face and I think about all I know about strata and the evidence in front of me and with all that in mind I try to work out how that strata came to look the way it does. This verse is like that strata. My task is to test a hypothesis or explanation for how it came to be there and to appear as it does.

So the explanation, or hypothesis, that I decide to test is: That James, whom Paul meets according to this letter, was a sibling of Jesus. That’s my initial explanation for this verse, or in particular this phrase, “James the brother of the Lord”, being there.

It seems pretty straightforward, surely. This should be easy enough to confirm.

So let’s set it out in the theorem structure. Continue reading “Putting James the Brother of the Lord to a Bayesian Test”

Scholarly Fallacy of the Week: Bart Ehrman’s False Dichotomy

Creative Commons License

by Neil Godfrey

The hermeneutic of charity is what some New Testament scholars (e.g. Richard Bauckham) have termed the goodness, the rightness, of believing a testimony by default — unless and until we are given a reason to doubt it.

It is usually opposed rhetorically to the idea of the hermeneutic of suspicion.

Charity and suspicion. The words clearly resonate with the ideals of the highest teachings of biblical love: “charity” being the best of gifts and “suspicion” being antithetical to that Christian virtue according to 1 Corinthians 13.

In fundamental logic, however, we might align these concepts with something more neutral and objective for analysis: the false dichotomy.

Bart Ehrman may shun the term “hermeneutic of charity” (I don’t know but I’m assuming he does) but he falls right into that same soft bed of roses no matter what their name. He does this many times, and so many New Testament scholars do, too, but we have a right to expect the highest standards from the highest paid professions.

In Did Jesus Exist? Ehrman falls within the wake of so many of his peers by setting up the so-called evidence of Papias as

  1. either reliable enough to be used as “an important source for establishing the historical existence of Jesus”
  2. or it is nothing but a bald-faced lie

This is a most unscholarly view of things. It has nothing to recommend it. It breaks all the fundamental rules of how historians are expected to analyse the value of their sources. It is nothing but a logical and methodological fallacy. But it is so commonly encountered in the writings of New Testament scholars that one would be excused for thinking it is a simple truism.

Here is how Ehrman presents his case based on the supposed evidence of Papias: Continue reading “Scholarly Fallacy of the Week: Bart Ehrman’s False Dichotomy”

Carrier’s “Proving History”, Chapter 3(a) — Review

Creative Commons License

by Neil Godfrey

I have been studying the first half of Richard Carrier’s chapter 3, “Introducing Bayes’s Theorem”, in his recent book Proving History: Bayes’s Theorem and the Quest for the Historical Jesus. I mean studying. I want to be sure I fully understand the argument before tackling the second half of the chapter, headed Mechanics of Bayes’s Theorem, which promises to be “the most math-challenging section of the book” (p. 67). Maths is not my most outstanding strength so I want to be sure I get the basics clear before moving into those waters. I have come to a point where I can enjoy playing little mind-games with Bayes’ Theorem for the sake of reinforcing my understanding. Last night on the TV news was dramatic story of an unexpected resignation of a leading Australian political figure. So I found myself piecing all I heard, how I heard it and what I knew etc. into a Bayes’ equation and calculating the probability that the story was true. Kind of fun. At least for the moment before the novelty factor wears off.

Result: While I believe I can see Richard’s point some of my niggling questions have not yet gone away.

When did the sun go out?

Carrier begins by setting out our reasoning when we read in the Gospels that darkness covered the whole earth for three hours at the time of the crucifixion of Jesus. What he is seeking to do is to take readers through the processes they would undergo in order to conclude that such an event almost certainly never really happened.

To make the scenario work he posits at least a barely conceivable natural cause for the event: “a vast dense cloud of space-dust swiftly drifting through the plane of the solar system . . .” — Wouldn’t the Sun’s gravity prevent that? But I’m happy to go along with the exercise for sake of argument nonetheless.

The critical point for Carrier is that what would convince us that such an event really had happened in the past is if we could find records testifying of the event across all world cultures thousands of miles apart from Britain to China.

There could not fail to have been mention or discussion of such a remarkable and terrifying event across many of these cultures among their surviving textual traditions and materials. (p. 43).

The key point is that we know in advance that this is the evidence we would expect to find IF such an event had happened.

And if indeed that were the case, we would surely have adequate warrant to believe the sun was blotted out for three hours on the corroborated day . . .

What Carrier is preparing his readers for is to accept that reasoning about historical events is fundamentally similar to reasoning in the sciences. If such and such a hypothesis (or explanation) is true then we would predict (or expect) certain events (or evidence) to be manifest.

Then there is the converse. If such a hypothesis (explanation) were true, we would NOT expect to find a universal silence in the surviving records:

[A] single claim in a single religion repeated only in its own documents (and documents relying on those), is extraordinarily improbable — unless the event was entirely made up. . . . This is a slam-dunk Argument from Silence, establishing beyond any reasonable doubt the nonhistoricity of this solar event . . . (p. 44)

My niggling question:

I follow the reasoning. But in my mind, rather than taking me into the realm of mathematics, it all leads back to my own argument about how historians know anything at all about the persons and events of the past. Continue reading “Carrier’s “Proving History”, Chapter 3(a) — Review”

Jesus Agnosticism: Believing vs. Knowing

What we can and cannot know

I confess I have often shown little patience for people who hide behind the label of agnosticism when asked whether they believe in God. It smacks of evasion, since it answers a question concerning belief with an assertion about the state of knowledge. That is, it redirects our attention to the axis of knowing — how much we know or can know — instead of telling us where one stands on the axis of believing.

So you can perhaps imagine how annoyed I’ve become at myself lately for describing my own position on the historicity of Jesus as “Jesus agnostic.” Have I fallen into the same trap as atheistic agnostics, too timid to answer the question that was asked, so I answer one that wasn’t?

Does agnosticism describe anything meaningful?

Most atheists are also agnostics. We lack the belief in God in the same way that we lack the belief in many things we can’t definitively disprove. However, we hold the existence of a supernatural being that fits the description of God to be so unlikely that we operate under the assumption that he does not exist.

Do we actively believe God does not exist? Actually, no. It takes no effort at all to lack a belief. For example, if you grew up as a Christian, you probably lack the belief in the transmigration of souls. Same here. People might reincarnate after they die, but I think it’s extremely unlikely. So I can truthfully say, “I don’t believe in samsara.” But I don’t spend any time thinking about it or actively disbelieving in it.

If by knowledge we mean rational knowledge based on human reason and physical evidence, a good many Christians are also agnostics. They believe without proof — “blessed are they that have not seen, and yet have believed.” (John 20:29b, KJV) They have made the “leap of faith.” Should they claim to have any knowledge at all, they will maintain they possess a knowledge of the heart, a feeling of the divine presence.

So if a great many of us — theists and atheists alike — agree that we can’t know whether God exists, is the term “agnostic” all that meaningful? Well, it is if you mean it in the loose, vernacular way that the popular media often intends it, namely as a description of someone who cannot decide. Perpetual fence-sitters, they simply can’t make up their minds. Continue reading “Jesus Agnosticism: Believing vs. Knowing”

Carrier’s “Proving History”, Chapter 2 — Review

by Neil Godfrey

This post continues from my previous one in which I began my review of Richard Carrier’s Proving History: Bayes’s Theorem and the Quest for the Historical Jesus.

Chapter 2: The Basics

Here Carrier pauses before addressing Bayes’ theorem in order to establish fundamentals that ought to be part of the basic mechanics of every historical enquiry.

The first subsection of the chapter is “Why History Requires Expertise”. Carrier opens by listing three golden rules he always offers lay people who ask him what history they can trust:

  1. Don’t believe everything you read;
  2. Always ask for the primary sources of a claim you find incredible;
  3. Beware of scholars who make amazing claims but who are not experts in the period or even historians.

I have learned to extend #2 to “always ask for the primary sources of all claims — including the commonplace ones”. Continue reading “Carrier’s “Proving History”, Chapter 2 — Review”

Richard Carrier’s “Proving History: Bayes’s Theorem and the Quest for the Historical Jesus” Chapter 1 (A Review)

by Neil Godfrey

Till now I’ve always been more curious than persuaded about Carrier’s application of Bayes’s Theorem to what he calls historical questions, so curiosity led me to purchase his book in which he discusses it all in depth, Proving History: Bayes’s Theorem and the Quest for the Historical Jesus.

Before I discuss here his preface and opening chapter I should be up front with my reasons for having some reservations about Carrier’s promotion of Bayes’ theorem. (Allow me my preference for Bayes’ over Bayes’s.) I should also say that I’d like to think I am quite prepared to be persuaded that my resistance is a symptom of being too narrow-minded.

My first problem with Carrier’s use of the theorem arises the moment he speaks of it being used to “prove history” or resolve “historical problems”. For me, history is not something to be “proved”. History is a quest for explanations of what we know has happened in the past. Historical problems, to my thinking, are problems having to do with how to interpret and understand what we know has happened in the past. The milestone philosophers of the nature of history — von Ranke, Collingwood, Carr, Elton, White — have certainly spoken about history this way.

I have always understood that where there is insufficient data available then history cannot be done at all. Ancient history, therefore, does not allow for the same sorts of in-depth historical studies as are available to the historian of more recent times. Historical questions are necessarily shaped (or stymied altogether) by the nature and limitations of the available sources.

Criteriology (I take the term from Scot McKnight‘s discussion of the historical methods of biblical scholars in Jesus and His Death) has always looked to me like a fallacious attempt to get around the problem of having insufficient data to yield any substantive answers to questions we would like to ask. We don’t know what happened? Okay, let’s apply various criteria to our texts to see if we can find out what “very probably really did happen”.

Carrier’s introduction of Bayes’ theorem has always appeared to me to be an attempt to salvage some value from a fundamentally flawed approach to “history” — the striving to find enough facts or data with which to begin to do history.

I should add that I do like Carrier’s offering of hope that Bayes’ theorem can promote more rigorous and valid thinking and applications of criteria. But I can’t help but wonder if in the end the exercise is an attempt to patch holes in the Titanic with admittedly very good quality adhesive tape.

What is really accomplished if we find only a 1% probability for the historicity of Jesus? Improbable things really do happen in the world. Otherwise we would never know chance and always be living with certainty. Or maybe I’m overlooking something about Carrier’s argument here.

Not that I’m a nihilist. I do believe we have lots of useful evidence to assist us with the study of Christian origins. I think scholars are agreed that pretty much all of that evidence speaks about a Christ of faith (a literary figure) and not an historical figure. That’s where our historical enquiry must begin — with the evidence we do have. After we analyse it all and frame such questions as this sort of evidence will allow us to ask then we can begin to seek explanations for Christian origins. This will probably mean that we will find answers that do not address the life and personality of someone who is hidden from view. Our understanding will address religious developments, ideas, culture, literature, social developments. We will probably be forced to conclude — as indeed some historians do — that if there is an historical Jesus in there somewhere he is irrelevant to our enquiry.

So that is where I am coming from.

Let’s see if I am being too narrow-minded. Here is my reading of Carrier’s preface and opening chapter. Continue reading “Richard Carrier’s “Proving History: Bayes’s Theorem and the Quest for the Historical Jesus” Chapter 1 (A Review)”

Everybody else in the world has been blogging about Dr. Bart Ehrman’s latest book on the existence of Jesus, and I didn’t want to feel left out. But the truth is there’s not much left to say. Yes, it’s a disappointment. And yes, we expected more and better from a respected, popular scholar. On the other hand, it wasn’t that big a surprise, was it?

We might, however, be forgiven if we found the tone of the debate a tad over the top. We have learned, as the hapless four-year-old protagonist in Lardner’s story discovered, that there is no way to ask Daddy if he’s lost that won’t bring a harsh response.

It does seem odd, however, to see scholars with advanced degrees — public intellectuals who teach real students at real universities — stooping to personal attacks. More disturbing than the abuse is the apparent lack of unawareness exhibited by the perpetrators, as if to say, “This is perfectly normal behavior.” Continue reading “The Democratization of Knowledge and the Reaction of Reactionary Scholars”

Historical Jesus Studies As Pseudo-History — Bart Ehrman’s Jesus As a Case-Study

Creative Commons License
This work is licensed under a Creative Commons Attribution 4.0 International License.

by Neil Godfrey

First let it be clear where I am coming from. This is not an attack on any scholar or the scholarship of theologians in general. It is an attempt to address what strikes me as very muddled thinking in many works about the historical Jesus. That is not a denigration of the scholars in question or the works they have produced. It is forthright attempt to address an assumption or understanding that appears to be generally overlooked. If my views are wrong then I would expect someone somewhere who knows better can point out in a reasoned explanation where and why they are wrong. That would cause me some embarrassment, no doubt, but at least I would be given the opportunity to change my views. I resolved long ago to be prepared to take the consequences of striving to be honest with myself in place of living a lie. But if the only response continues to be ridicule or insult or silent dismissal I will have no reason to think my criticism is invalid.

Often when I read a scholarly study of the historical Jesus I am a little dismayed at the woolliness of the ideas addressed. I have slowly become convinced that very few scholars who have written about the historical Jesus have ever studied what history even is. Very often historical evidence is confused with stories or an assumption that a story must be derived from real happenings.

Now I do understand that when Bart Ehrman wrote Jesus: Apocalyptic Prophet for a New Millennium (=JAPNM), he wrote it not for his scholarly peers but for a wider public:

Scholars have written hundreds of books about Jesus . . . . A good number of these books, mainly the lesser-known ones, have been written by scholars for scholars to promote scholarship; others have been written by scholars to popularise scholarly views. The present book is one of the latter kind . . . . (p. ix)

The woolliness of thinking about the distinction between the narrative of an event and evidence for a real historical event, and even about the nature of history itself, is a critical consideration given that Ehrman also writes in the same preface:

The evidence itself plays a major role in this book. Most other popular treatments of Jesus rarely discuss evidence. That’s a particularly useful move — to avoid mentioning the evidence — if you’re going to present a case that’s hard to defend. Maybe if you just tell someone what you think, they’ll take your word for it. In my opinion, though, a reader has the right to know not only what scholars think about Jesus . . . but also why they think what they think. That is, readers have a right to know what the evidence is. (p. x)

Since my first draft of this post a new book by Ehrman has appeared (Did Jesus Exist? =DJE) in which he underscores the same fallacies running through JAPNM and adds a raft of new ones. For example, he lists a number of sources that he says historians can rely upon to establish the historical existence of a person while failing to notice that a number of the sources he lists can just as easily be used to argue for the historical existence of several pagan gods and demi-gods. (No wonder he finds they conveniently support the historicity of Jesus!) Equally bad, almost all of them ultimately beg the question of historicity rather than confirm it. I will discuss the logical fallacies inherent in his list in a future post.

What is history?

There are two fundamentals that I learned in about history in my senior history classes.

  1. The first thing I learned in my history class at senior high school was what history is not. History is not a list of facts, dates and events. A list of events is a chronicle, not history. History is the study of past events, an exploration in understanding those events, the composition of a narrative to convey some story or meaning from those past events. Such a narrative invests the “facts” with interpretation and meaning.
  2. The second was that when it comes to ancient history historians can only study questions for which we have enough raw material to research. We can’t write a biography of Socrates examining the range of formative influences upon his thinking and assessing how much of his contribution to Greek philosophy was unique to his own genius, for example.

Let’s unpack these a little. Continue reading “Historical Jesus Studies As Pseudo-History — Bart Ehrman’s Jesus As a Case-Study”


Richard Carrier interview

Bayes theorem
Bayes theorem (Photo credit: disownedlight)

Richard Carrier is interviewed by John Loftus on “Debunking Christianity”and the topic is mythicism and the place of Bayes’ Theorem. If mathematics helps clarify the thinking of many then it can only be a good thing. I personally have not seen that it is necessary, and that worthwhile thinkers routinely seek to identify and account for the assumptions, the details and identifying fallacies in their arguments. Good arguments do make explicit all the assumptions etc without the need for mathematics to draw them to our attention. That one is reading a story about an event and not directly accessing an event, the ability to examine the nature of the story itself, for example, or being able to justify clearly why an argument is “not persuasive or plausible” instead of just saying “that’s not plausible or that’s weak”, or why an event is more or less probable, and the careful weighing (with intellectual honesty) the alternative explanations, and that any chain of reasoning ultimately has to factor in its weakest link. . . .

The good and diligent historians do make these things explicit and clear. It is the muddle-headed ones, one might say, that don’t. If Bayes is going to help the latter then that’s not a bad thing. I really do think that much of the problem among theologians who identify themselves as historians have never really been “trained” in historical studies and have never been trained in logic or philosophy. Clear thinking skills — as evidenced by the regularity of circular arguments, special pleading, unexamined assumptions — seem minimal in all too many of their works that relate to “the historical Jesus”.

But as Richard implies, such clarity of thinking does not come to us naturally. It does take a lot of “training”. But I don’t agree that this sort of training need be the preserve of “experts”. Those with enough interest and effort can learn how to improve their ways of thinking and how they read works and formulate their own ideas. (And much of that training can come from wide reading of the very best in the field.)

Here are a few excerpts of the bits that particularly appealed to me: Continue reading “Richard Carrier interview”

It is an attempt to address what strikes me as very muddled thinking in many works about the historical Jesus. That is not a denigration of the scholars in question or the works they have produced. It is forthright attempt to address an assumption or understanding that appears to be generally overlooked. If my views are wrong then I would expect someone somewhere who knows better can point out in a reasoned explanation where and why they are wrong. That would cause me some embarrassment, no doubt, but at least I would be given the opportunity change my views. I resolved long ago to be prepared to take the consequences of striving to be honest with myself in place of living a lie. But if the only response continues to be ridicule or insult or silent dismissal I will have no reason to think my criticism is invalid.

Often when I read a scholarly study of the historical Jesus I am a little dismayed at the woolliness of the ideas addressed. I have slowly become convinced that very few scholars who have written about the historical Jesus have ever studied what history even is. Very often historical evidence is confused with stories or an assumption that a story must be derived from real happenings.

Now I do understand that when Bart Ehrman wrote Jesus: Apocalyptic Prophet for a New Millennium (=JAPNM), he wrote it not for his scholarly peers but for a wider public:

Scholars have written hundreds of books about Jesus . . . . A good number of these books, mainly the lesser-known ones, have been written by scholars for scholars to promote scholarship; others have been written by scholars to popularise scholarly views. The present book is one of the latter kind . . . . (p. ix)

The woolliness of thinking about the distinction between the narrative of an event and evidence for a real historical event, and even about the nature of history itself, is a critical consideration given that Ehrman also writes in the same preface:

The evidence itself plays a major role in this book. Most other popular treatments of Jesus rarely discuss evidence. That’s a particularly useful move — to avoid mentioning the evidence — if you’re going to present a case that’s hard to defend. Maybe if you just tell someone what you think, they’ll take your word for it. In my opinion, though, a reader has the right to know not only what scholars think about Jesus . . . but also why they think what they think. That is, readers have a right to know what the evidence is. (p. x)

Since my first draft of this post a new book by Ehrman has appeared (Did Jesus Exist? =DJE) in which he underscores the same fallacies running through JAPNM and adds a raft of new ones. For example, he lists a number of sources that he says historians can rely upon to establish the historical existence of a person while failing to notice that a number of the sources he lists can just as easily be used to argue for the historical existence of several pagan gods and demi-gods. (No wonder he finds they conveniently support the historicity of Jesus!) Equally bad, almost all of them ultimately beg the question of historicity rather than confirm it. I will discuss the logical fallacies inherent in his list in a future post.

What is history?

There are two fundamentals that I learned in about history in my senior history classes.

  1. The first thing I learned in my history class at senior high school was what history is not. History is not a list of facts, dates and events. A list of events is a chronicle, not history. History is the study of past events, an exploration in understanding those events, the composition of a narrative to convey some story or meaning from those past events. Such a narrative invests the “facts” with interpretation and meaning.
  2. The second was that when it comes to ancient history historians can only study questions for which we have enough raw material to research. We can’t write a biography of Socrates examining the range of formative influences upon his thinking and assessing how much of his contribution to Greek philosophy was unique to his own genius, for example.

Let’s unpack these a little. Continue reading “Historical Jesus Studies As Pseudo-History — Bart Ehrman As a Case-Study”

Is the sun a ball of dung?

The ancient Egyptians believed that Kephri, a god with the head of a sacred scarab, pushed the sun along its path, just as the dung beetle pushes a ball of dung across the ground. They were convinced that the beetle existed in male form only, and reproduced by fertilizing its dung ball with beetle semen. This life-giving attribute relates to Kephri’s ability to resurrect the sun each morning.

The irrational anti-supernaturalist would dismiss these beliefs out of hand, while the credulous, unlearned person might simply accept them without question. But the reasonable, wise, modern scholar takes the middle road and declares, “How do I know? Neither the scientific method nor the historical-critical method can account for miracles.”

Methodological Naturalism

We call this perspective “methodological naturalism.” It skirts the issue of whether the world in reality is affected by supernatural forces. Rather, it asserts that having only naturalistic tools in our bag, the only things we can measure and be sure of from a scientific standpoint are natural phenomena. We don’t assert radical materialism; we just operate that way.

But let’s be honest. We’re not talking about just any supernatural forces. Egyptologists don’t have to calm down their students by telling them “we’re just not sure” about how the sun moves and whether dung beetles have no wives. No, we invoke methodological naturalism only when existing religions with existing beliefs in the supernatural intersect with historical studies.

We don’t do it for other ancient gods and defunct ancient religions. We don’t do it in modern forensic science. We don’t do it in scientific research. We only do it when we look at ancient texts that are revered by modern people.

If we don’t drill a hole in your head, then how will the demon get out?

Many conservative scholars (e.g., Paul Eddy and Greg Boyd) argue strongly for a new “Open Historical-Critical Method,” wherein we give our ancient “witnesses” the benefit of the doubt when it comes to little things like the resurrection of the dead, but surely they do not also argue for an “Open Theory of Disease.”

Maybe you have a chemical imbalance, or maybe you have a demon. Perhaps you have cataracts, but let’s leave open the possibility of some supernatural creature that’s living inside your eyes.

They wouldn’t argue that, would they? I mean, this is the 21st century, right?

Right? Guys? Continue reading “Miracles and Historical Method”
