Such boxes were derived from past experience. Once the boxes were established, it then became a matter of fitting new experiences into the standard boxes. Analysis breaks things down so they can fit more easily into boxes. Once something is judged as fitting into a box then we read the label to determine the appropriate action to be taken. The doctor diagnoses measles by the symptoms that suggest the 'measles' box.
Action is determined by the label or instructions on that box.
The UN has failed in Somalia, Bosnia, Haiti and Rwanda because the UN was set up to deal with conflicts between sovereign states. These boxes have proved useless in the situations mentioned. So we are trapped in a thinking system based on truth and boxes. We search for the truth by seeking to remove the untruth. But if we remove the bad and untrue, we must surely be left with the good and true.
