"i am baiting you again, clearly."
Yes, and more desperately than usual.

The author of Acts, Luke, speaks approvingly... not of the 'massive destruction of knowledge' but of books of sorcery.
"i have already made the point (helpfully corrected by the newly reincarnated Sir Somebody Solaris) that destroying a book in the age of mass publication can hardly be compared to destroying a book in the first century CE."
Said only by someone living in the age of mass publication. Presumably, a person living in the first century AD knows better then you and I do the value of a book. But I suppose our first century citizens should have known that 2,000 years hence they'd be churning out books by the millions and even replacing them with computers? This whole line doesn't seem like an argument, it seems more like you're just looking for any thing to throw hoping something will stick. That's just my take. :)
"i'm sorry to use Nazi imagery, by the way, but it's the easiest parallel to draw. i dont mean to imply anything other than relying on a source that approved of the destruction of certain knowledge to tell you exactly what that knowledge was is a little naive."
But the problem is that you are making assumptions in the other direction. You want to try to concoct a Christianity that was hell bent on stifling dissent left and right thus throwing into doubt everything we know about Christianity (and if you were consistent, the entire ancient world) based on... a little passage about people who used to be sorcerers
burning their own books.
Presumably, these converted sorcerers didn't think their books had any value. That was their own, individual, personal call. You don't want to take their word that it was rubbish, that's fine, but to try to paint it as some sort of systematic program is simply not warranted. In short, if that's the argument you want to make, I'm going to make you earn it with more than pot shots.

It isn't merely an argument for the sake of argument to me. If this is holding you back from the faith then I think it needs to be addressed and your own personal integrity will drive you to see how grounded in reality this perception of yours is.
"You suggest that it was impossible for Christians to have any power to suppress rival viewpoints until at least 315CE?"
In the systematic way implied by your argumentation? Absolutely not.
"i dont know, are we treating this as historical again? How should i interpret the intervention of Zeus (or whoever) in the seige of Troy, according to you?"
I don't discount the possibility that Zeus (or whoever) intervened at Troy.

But you're still baiting me but I'm not going down this road in this thread. Haven't we enough on the table? :)
"i am aware of that. But from the link you provided you presumably agree with me that certain early Christians had great hostility towards the 'heretical' knowledge contained within the library, and probably had at least some responsibility for its destruction."
I'm not willing to go that far. The purpose of the link was to show that there have been other ideas floated. I mean, even the disparity in the dates should cause you to wonder. When did the library burn down? The accounts/stories/rumors are spaced out over like 800 years. Except for knowing that it burned down I'm not sure anyone really knows the details. I haven't studied it, but from past readings that is about where I stand on it. If you'd like to make a federal case out of it then it would be fun to get back into the data.
"Did you ever read "Cosmos", by the way? It seems only fair since i read that Chesterton stuff at your request."
Cosmos by who? Sorry, I'm a lout. I don't even remember you suggesting it. What about Abolition of Man. Did you read that, too?
"That's a complicated question."
Read: If I answer this directly I may admit the man's point.
:)
"That aside, no, go ahead. be prepared for some fairly scathing reviews in medical journals though."
So, in other words you concede the point. That's a lot of words to say, "Yea, the medical community has the right to go after you." :)
"For this to be even an approximate analogy i would have to allow you to assume an awful lot of knowledge which i know for a fact you do not have about the contents of the "sorcery" books in Acts."
Be careful!
"For all my caveats about the medical science community, there are some reasonably good safeguards against such a thing happening."
More words to basically grant the point. But watch how you segue from 'reasonably good safeguards' to 'these nasty knowledge suppressing Christians..."
"but simply noting that by selecting certain 'knowledge' as the truth (
based on its congruence with previously held 'truths'),"
Whoa. Hold the phone. If they were merely attempting to be congruent with previously held truth then they aren't selecting anything, are they? They are merely affirming.... 'previously held truths.' If Christians had really believed that Jesus was God all the way back to the time of Christ they aren't 'selecting' anything. Why should some dude get to come in and say "But I think they are all wrong, three hundred years of Christians got it all wrong" and you, Dannyboy, think he should get a fair hearing.
I mean, it just seems to me that if you're a decent fellow you'll just go out and start your own religion instead of co-opting someone else's.
How dare these people affirm what had been consistently and virtually universally believed for three centuries!
"i wonder why you do not apply the same logic with much greater force to the deliberations of the Council of Nicea."
I think it probably has something to do with the fact that I've read widely in the writings of Christians between the Council of Nicea and the writing of the books of the New Testament. You're concerned about doctrinal 'cherry picking' but it is just hard to make that case when you're reading Justin the Martyr, Tertullian, etc, etc, and see 'mere Christianity' come out clear as day throughout.
Just to give a common example of this madness... it is widely asserted in skeptical circles and given popular currency in the Da Vinci Code that the notion of Jesus being God and God as trinitarian came about at the Council of Nicea. But I know for a fact that Tertullian, whom I just mentioned, coined the term in early 200s, a solid 150 years before the council. For Tertullian to coin the word the concept already had to have had currency, and there isn't a whole lot of time between the founding of Christianity and Tertullian's coining for people to be developing doctrines out of nothing and whole cloth. Nor is there record of any of the Church fathers objecting to Tertullian using the word. Indeed, the concept can be traced in the writings of those who preceded Tertullian.
Since I know this, I confess it chafes my hide when I hear people assert otherwise. I mean, don't they bother to open books? (I hear think of someone like Dan Brown, who ought to know better).
Most of the people who like to play with the whole "The 300 folks who got together in 315 to selectively cherry pick their favorite doctrines and repressed all the rest" haven't usually bothered to study the previous 250 years to see if their hypothesis stands up.
