These arguments are fairly detailed, are they not?
Yes and no (the logic is fairly straightforward). But they do require, among other things, a knowledge of Greek to evaluate.
Whenever one studies a certain problem in great depth, there is danger that you will get so sucked into the minutia of the details, that you lose sight of the big picture.
That does and can happen. But when it does there are always plenty of others to point it out. I wasn't a big fan of N.T. Wright's three-volume work on the historical Jesus (particularly as the third leaves the realm of historicity), but I did like his comments in the second volume about some work of those who have so intensely studied Q: "to treat Q as a document at all is controversial. To treat it as a gospel
is more so; to postulate two or three stages in its development is to build castles in the air; to insist that the document was composed in the fifties, and possibly at Tiberias in Galileee, is to let imagination run riot" (p. 48).
I think it is certain that intense scholarly study can drive some people insane: staring for hours at all those texts.
Typically, those who do stare "for hours at all those texts" are of the type for whom such study will not drive them insane. Some people practice a given sport or musical instrument for hours. Iaido is entirely devoted just to prefecting drawing one's sword, and practitioners spend hours and hours repeating their draw. I spend hours and hours "staring" at texts and I spend hours and hours training (combatives/CQB/edged weapons/stick/etc). Neither has driven me insane. When it comes to psychotic disorders, I think you will find more of these among mathematicians, theoretical physicists, and similar academics than those whose work involves intense study of texts.
I wouldn't say that Eisenman shows signs of insanity, exactly,
And I wouldn't use him as a yardstick to judge even NT scholars, let alone the entire community of scholars of ancient history.
I can almost see him slowly going insane as he minutely picks through all of those tiny fragments, can't you?
I've done it.
It seems that a scientific one can; just look at superstrings
We can't (not yet anyway, and we may not ever be able to even if, for example, M-theory is accurate). Lots of things within mathematics and physics seem counter-intuitive or even insane. But unless you have good reason not just to reject string theory but call it insane (which means you must have a grasp of QM and GTR physicists lack), why do so?
The violent attacks on Gibbon trouble me.
It's hard to violently attack someone who is dead. Also, the "attacks" aren't on Gibbon. They are an expression of incredulity at your religious devotion to him.
It is good enough for people outside of the scholarly community
It isn't. In fact, it's a pretty bad source for anybody, scholarly or no, to use to acquaint themselves with roman history. Not only are there far more reliable works which are far shorter and more readable for the non-specialist, those who do read Gibbon don't do so to understand roman history (anymore than one reads Shakespeare's
Julius Caesar to understand the historical events surrounding Caesar's death).
it acquaints the nonspecialist with all of the most important facts
Such as?
and the fact that it is from 1776 actually works to its advantage for this purpose, because it is written at a higher literary level than the pop literature of today
Making it less accessible to most.
The problem with Paul's biography is that it comes from Paul.
And Acts.
This is the definition of a tendentiousness source. The interpretation of Acts seems even more difficult: how are you going to pick out the little deposits of fact from that confusing mass of mythical and polemical fantasy, without going mad?
Why not read some scholarship on the subject and see?
Any number of reasons. For example, John the Baptist continued to have followers after his death. Yet Josephus doesn't mention him or his followers in
De Bello Iudaico. He does, however, in
Antiquitates Judaicae. This is also where he mentions Jesus.
I'd like to know what the scholarly consensus is on this problem.
That it isn't a problem.
