Re: Top-Down Bottom-Up Methodology
Jim,
I don't know of any paper about what you are asking in your mail.
Your proposal seems good.

But in my opinion some kind of shared culture/knowledge/experience is
also needed.
I don't have data about that.
Personally I'm still working on very basic issues, such as Peirce's
ideal - realism, related to my "thirdness practice".
This what Peirce says about ideal-realism.
"This is the opinion that nature and the mind have such a community as
to impart to our guesses a tendency toward the truth, while at the same
time they require the confirmation of empirical science".
( The Essential Pearce Vol 1 - Indiana Univ. Press 1992 -
in N.Houser Introduction pag. XXV).
The problem appear to be how to do it with representations of the "real
world".
Best wishes
