If real history books get it wrong and contradict each other ?
Yes, that is exactly to what I was referring to. They get it wrong and contradict too, so why can't a fictional history book?
All that being said, I don't think it's a problem. I'm sure somebody out there can make a mountain out of a molehill because I ignore certain PF or interpret it for my own ends. Oh well. It's just a game.
Well, then the problem I have is rather those people that cry "U r doin it rong!" than the book. Then again, those people that take EVE: Source to be the non plus ultra in deciding canonicity are backed up fiercly by CCP there. So again, not so much a problem with the book in itself (aside the usual failings of EVE lore) but with how CCP advertises it as the ultimate answer to everything (despite internal inconsitencies).
As to the Gallente/Caldari portrayal in EVE: Source. I really just skimmed over it (and as I said am no expert for the background there anyway), so I didn't notice any contradictions there, but I have no problem to adjust my prior misconceptions there.
As to the Amarr having at least something in regard to their culture being better off than the Matari: I'd rather have preffered to not get what they wrote on Amarr culture there.
The letters of Bishop Dalamaid have been the subject of volumes of intellectual discourse. The primary contention of the letters, that true saintly martyrdom is an impossibility for anyone even aware of the concept of sainthood, has gone through various levels of favor over the generations.
How does that fit with a literalist, unchanging interpretation of the Scriptures ?
I don't think that's a view that exists. The Scriptures have always been in flux, and they are constantly being reinterpreted. They are so voluminous that no-one can ever have encyclopedic knowledge of them, and thus no-one can obey them in their entirety. Every new Emperor, every new High Deacon, and every new scientific discovery will change the orthodox intepretation.
"Indeed, it appears the general feeling is that
any attempt to do so [to rephrase scriptural truth in different words] would be not only useless but also rather unseemly - perhaps even sacrilegous." - EVE Source
So, according to this, the TC/Emperor might add or take away from the Scripture, there is no interpretation possible if you can't rephrase the truth in Scripture by other words than those Scripture uses. So, according to EVE Source Amarr would have to go by a) a literal interpretation or b) by the idea that any interpretation that is non-literal can't be expressed. Of course that conflicts with prior PF on the nature of the Amarr Scriptures, but EVE: Source is supposed to overrule previous PF...
