You should go to picture-galleries and museums of sculpture to be acted upon, and not to express or try to form your own perfectlyfutile opinion. It makes no difference to you or the world what you may think of any work of art. That is not the question; the point is how it affects you. The picture is the judge of your capacity, not you of its excellence; the world has long ago passed its judgment upon it, and now it is for the work to estimate you.
