ISR research forum

I was in ISR research forum today. There are some interesting points worth noting:
Some guy conceptualizes a spectrum of knowledge from data, information, knowledge, understanding and wisdom, and suggests that data, information, knowledge and understanding are for efficient, wheras wisdom is for effective.

The same guy also gives a two dimensional conceptulization of knowing:

"I know what I know" "I know what I don't know"
"I don't know what I know" "I don't know what I don't know"

Interesting, I hope at some point, I will know what I know, and also know what I don't know.

I love the words "it is not here yet, but we are concerned with how to pass from here to there". I very much appreciate these words at this stage of my life.
