That the mere matter of a poem, for instance--its subject, its given incidents or situation; that the mere matter of a picture--the actual circumstances of an event, the actual topography of a landscape--should be nothing without the form, the spirit of the handling, that this form, this mode of handling, should become an end in itself, should penetrate every part of the matter;Mthis is what all art constantly strives after, and achieves in different degrees.
