David--
Please excuse a non-scholarly response, but I'm
reminded of a salient portion of a Willie Nelson/Waylon Jennings song, "Reasons
to Quit":
The reasons to quit // Don't outnumber all the
reasons why.
The song (like the scholarship) provides a laundry
list of "reasons to quit," but nowhere does the lyricist feel the
need to itemize the "reasons why"--it's assumed we already know
why.
