Models of What Used To Be

We like to think sometimes everything can be saved, but not everything needs to be preserved, at least not in its present state; and so it is progress, even if it may not always seem to be, for some organizations or institutions to give way, to become so different as to stop altogether.  Their salvation (if such be the word) is in becoming what used to be.  They can serve as the model of what used to be, a time when a need was met for that time, but it is a time that is over.
