I went to the Davids' house this morning... and talked with son David about some of the work he is doing for the San Diego Museum of Art.  He showed me some photographs of the work of American artists... very impressive.  After going home, I picked up a book, unrelated to what David and I talked about... and I read a statement by Albert Einstein. He said, “The true sign of intelligence is not knowledge but imagination..." and on another day he said, “Logic will get you from A to B. Imagination will take you everywhere.” One of my kids gave me a shirt that has on it a quote from Einstein, “Imagination is better than knowledge.”  I think the man was onto something...
