" But while speaking against fretting after eccentricity, don't let it be assumed that any discouragement is being given to genuine new points of view. In art, when a thing has once been well done and has found embodiment in some complete work of art, it has been done once for all. The circumstances that produced it are never likely to occur again. That is why those painters who continue to reproduce a picture of theirs (we do not mean literally) that had been a success in the first instance, never afterwards obtain the success of the original performance. Every beautiful work of art is a new creation, the result of particular circumstances in the life of the artist and the time of its production, that have never existed before and will never recur again.
