I think that the art is separate from the artist. The art not only express a unique particular sliver of the artist's interior world , but also a composite of the collective. The implication is that when other human being sees, appreciate the art that just came about by the creation of the artist, in his/ her particular interpretation adds something from his/her own interior life. As a result the art piece being appreciated is not exactly the same that came out of the hand of the artist, because it has the value added conferred by the eyes of the beholder. In one word, one the art is exposed to others , acquires its own life, independent from its creator.
