Total quality management

Today as I was reading a book about total quality management. I came across the following paragraph.
what is said here largely reflects what ails diabetes education.


A philosopher, Moshe Hayyim Luzzato (1707-1747) wrote:
"I have not composed this work to teach people what they do not already know, but to remind them of what is known to them. For the most of what I have to say is nothing more than what most people do know. But what is said in the following pages is constantly ignored most often forgotten, because it is common knowledge and obvious. That is why no profit will be derived from a single reading of this book, for quite likely after such a reading the intelligent reader will, find little that is new. Only constant reading and rereading will prove beneficial."
