Robert Louis Stevenson said this quote

Literature, although it stands apart by reason of the great destiny and general use of its medium in the affairs of men, is yet an art like other arts. Of these we may distinguish two great classes: those arts, like sculpture, painting, acting, which are representative, or as used to be said very clumsily, imitative; and those, like architecture, music, and the dance, which are self-sufficient, and merely presentative.
