Complies with the Uncertainty Principle and Incompleteness Theorem, as well. ;)
I like the quadrant idea, but suspect it requires a Z axis to represent maintenance of a particular, specific, singular viewpoint over time, causing a corresponding frameshift relative to the generalized, average view. A point of view that was once Centrist and balanced between the 4 quadrants can thereby become an extreme of any of the 4 qualities by virtue of the shifting of the contextual frame. As in, the grid moves around the thought in addition to the thought moving within the grid.
Assuming, of course, that we can simplify all forms of communication to Certainty, Doubt, Reliability, and Bullshit :D
