RE Mimara seeing herself as good, and whether the judging eye exists...this may sound like terrible reasoning, but the two biggest reasons I have faith that the judging eye is special and really is some important thing, even if it is actually not inviolably accurate or correct, is:
-Bakker titled a book after it. Other things he titles his books do seem to often be somewhat false, not entirely true to what we were told they would be. But they also have some kind of substance.
For example:
Is Kellhus, warrior prophet, an actual prophet? Apparently not - Kellhus himself believes or seems to believe he is patently not a prophet. But all the same, does that feel like an excellent title for Kellhus, even when it's false? Ya, it seems pretty perfect. So many shams in Earwa pull off their sham effectively for a decent period of time.
-If Mimara just sees herself as good because the judging eye is a sham and she thinks better of herself than others because that's only human, why don't most of humanity think they have the judging eye? Why is it worth telling us she has the judging eye and titling a book after it? Why not exclude having the judging eye be a particular sham, but just include examples of people who think they judge objectively but in fact judge w/out any consistency, integrity or truth? Pretty much everyone in Bakker's works do that to some extent.
Possibly TJE will turn out to not be the absolutely reliable measure of all moral value, but probably still does represent some distinct, important or unique viewpoint or opinion (or aggregate of opinions). Perhaps TJE will turn out to be the rough, averaged opinion of all the conflicting viewpoints and perspectives in Earwa smushed into one, with all the contradictions and confusions accepted - I got no clue.
Reading the Great Ordeal.
A few questions:
-Did Kellhus ever do the grasping? Does he dream the dreams of Seswatha directly?
-When did Achamian's dreams begin to alter from what we understand as the more standard version of the dreams the mandate get?
Finally an observation: this may be something that occurred to people already, but the dunyain and the mandate vaguely remind me of the first and second foundation in Asimov's foundation series. The difference is that while the second mandate was created as a sort of shadow behind the first, the mandate and the dunyain were conceived of separately, and act independently. The dunyain don't seem to have been particularly aimed at controlling, combating, manipulating or allying with the consult, the men of the tusk or the mandate, or with a historical context. They were simply bread and brought up in such a way that they are apparently uniquely capable of doing so. I don't think it is of importance to argue that Bakker was or was not following the model of Asimov or any other author, but I found it interesting anyway.
Quite probably there are earlier books than the Foundation series that had such a structure of specialized institutions with parallel purposes.
I'm currently in the US hardcover on pg 199 of TGO. If you think the answers to my questions appear after that point, you could hold off. If you think they were in prior books (or even earlier in this book if I was inattentive) please let me know the answers. I might wanna reread this series eventually but right now I just wanted to catch up a bit.
Finally, this may be an obvious conclusion to many at this point, because it seems obvious to me, but do you think Akka's search will end up approximating the discovery of what Bakker meant or has come to mean by "The Darkness That Comes Before?" (what kellhus may refer to as the head on the pole behind him)
