Context

“Nay, is it not the most difficult on earth and the parent of all? And if life is short and art long, is not money still longer? And are not works of art, for the most part, more or less works of money also? In so far as a work of art is a work of money, it must not complain of being bound by the laws of money; in so far as it is a work of art, it has nothing to do with money and, again, cannot complain. It is a great help to the spectator to know the subject of a picture and not to be bothered with having to find out all about the story.” source
