Interesting, I suppose you are looking at chapters written by Moroni because they presumably would be free from Mormons editing?
That would be one logical starting point for close examination of the text.
Moroni's "voice" is ostensibly present in the book of his name -- and then
again in parts of Ether. If Moroni was a single person (one distinct writer),
then we should be able to produce a discrete "word-print" for him, and then
compare its pattern across the entire Book of Mormon. If we've assumed all
of the above correctly, then that "voice" should only appear in the last
two BoM books. If it appears elsewhere -- or if a "foreign voice" occurs
where we expect to hear Moroni -- then that would be troublesome.
Yes -- but I am uncertain of Nephi's source material. In many
places the text purports to be "pure Nephi," but in some places
(such as in Jacob) we evidently do not have "pure Nephi." So
I'm less eager to wade into Nephi's texts than Moroni's.
Yes, I understand what you are saying. But keep in mind the fact
that pca charts are not purposely designed to separate out individual
authors from a mixture of texts. Where the charting performs that task,
it is a by-product of the software program's primary function -- of
displaying deviations from the mean of the totality of texts/authors.
Again, this may be something important --- but pca charts can only
provide us with some hints of what to investigate by other means.
They are "looking through a glass darkly" -- by which it is easier
to discern wide separations of plots, than it is to discern the
content and origins of clustered plots.
I think you've got some interesting ideas going here --
but it will take other researchers, using other means,
to better address those issues.
