Many words that appear in the Torah are synonyms, or at least approximate synonyms. For example, sakal and ragam or amar and diber. Many people have observed that synonym choices tend to be correlated, so that, for example, in a parsha in which sakal appears one is more likely to find amar, while in a parsha in which ragam appears one is more likely to find diber. In fact, there seem to be certain broad patterns of such correlations, the details of which are not crucial at the moment.

Consider now the following hypothetical reactions to such observations.

A acknowledges such correlations provided that the medrash and/or the classical meforshim already did so for purposes of drush or parshanut.

B acknowledges them and is willing to use them as the basis for new speculative drush and parshanut.

C observes that the overall picture of such correlations suggest different "layers" of texts and speculates about the meaning of such distinct layers, but draws no conclusions from this about authorship.

D notes to himself that careful analysis of the "layers" seems to suggest multiple authorship, but is not disturbed by this because there is no reason that a Divinely authored document could not look like the product of multiple authorship.

E is convinced intellectually that the evidence points to multiple authorship but remains emotionally in the grip of the standard frum perspective he has always held and intends to continue to hold.

F is no longer in the emotional grip of the frum perspective regarding authorship of the Torah but retains enough emotional attachment to the overall frum narrative that he continues to live a frum life and to educate his children accordingly.

G is emotionally detached from the whole frum narrative but continues to live a frum life and to educate his kids accordingly out of respect, allegiance and the conviction that it is a good way to live.

H is emotionally detached from the frum narrative but stays frum in order to be better able to be meisis umadiach by spreading the gospel of higher Biblical criticism among the youth.

There is obviously a bright red line between some consecutive pair of these. Where would you put that line? (If you have a hard time answering a different question -- which letter you are -- the answer is that you are the letter right above the place you put the red line.)
