It begins to look as if there were an art, or a gift, which criticism has largely ignored. It may even be one of the greatest arts; for it produces works which give us (at the first meeting) as much delight and (on prolonged acquaintance) as much wisdom and strength as the works of the greatest poets. It is in some ways more akin to music than to poetry-or at least to most poetry. It goes beyond the expression of things we have already felt. It arouses in us sensations we have never had before, never anticipated having, as though we had broken out of our normal mode of consciousness and "possessed joys not promised to our birth." It gets under our skin, hits us at a level deeper than our thoughts or even our passions, troubles oldest certainties till all questions are reopened, and in general shocks us more fully awake than we are for most of our lives.
