Explaining why something is important diminishes it's importance. It's not important to explain why something is important. It kills perceived value. Or as NNT said: Never explain why something important is important. Go figure.

Importance is an observation realized, not a realization observed.

A contextual environment is a triple consisting of:

(i) an articulated context,
(ii) an intensional model, and
(iii) certain anchoring relations relating context and model.
