"Bravos, Tom. Earlier, in the last century, academics taught us that "Q sort" was the cognitive process which would allow those of us living in downtown Chicago to "miss" the car alarms and our out of town guests to "hear" that "loud noise" which was conditioned to reside, after daily harmless exposure, deep below our radar. Please, allow me to share. "Information is data endowed with relevance and purpose" so wrote Drucker. Evidence, ah, yes, hearing that word brings Tufte to mind. Beautiful Evidence, indeed. Lastly, the words of Octavio Paz "Wisdom lies neither in fixity nor change, but in the dialectic between the two." Cheers!" - Dave Martin
