Looking for a Few Good Words

Recently, Chuck Howarth and I were talking about the need for a good "museum quote" for a report. So I diligently began searching the web, he our bookshelves for a good quote about why museums are great. I also went to the AAM site and other quote search engines. Would you believe there is even a Quote Museum? I found some, err, interesting ones. Here's a few:

“Most convicted felons are just people who were not taken to museums or Broadway musicals as children.” –Libby Gelman-Waxne

"One time I went to a museum where all the work in the museum had been done by children. They had all the paintings up on refrigerators." –Stephen Wright "The museum spreads its surfaces everywhere, and becomes an untitled collection of generalizations that mobilize the eye." –Robert Smithson

...that's not the sort of thing that will inspire a potential donor or warm the cockles of one's museum-loving heart. So I'm putting a call out to the museum world to ask: what are some good quotes that you think do a good job of summing up the value of museums?
