From a talk at the Getty in 2006 -
"I wrote the following of Ansel Adams but I think it is probably true of artists in general: The artists is finally interested in demonstrating to himself by the authority of his work that his world is not an illusion - not an invention of his imagination, but rather a real world of which he is therefore a real part. Of course, that is a very ambitious goal...but, it's not necessary to succeed. It's necessary only to think one has a chance."
