"When the artist is alive in any person, whatever his kind of work may be, he becomes an inventive, searching, daring, self-expressive creature.  He becomes interesting to other people.  He disturbs, upsets, enlightens, and opens ways for a better understanding.  Where those who are not artists are trying to close the book, he opens it and shows there are still more pages possible."
