So goes one of the proverbs of Solomon. While some of the great king's sayings have not withstood the test of time, this one makes intuitive common sense. The dynamic behind it is not difficult to understand.
Vision is renewal, part of the process of human life.
The systems in which human beings live tend to stiffen and lose the capacity to regenerate themselves, as does any form of biological life sooner or later. For awhile, matters will seem to move as they always have. The system will operate according to the language of its original vision. But nature moves in cycles, and cycles eventually bring crisis. If vision has not been renewed, if places and changes in cycles have not been seen, not envisioned into the system, it collapses and the people perish.
