What a poem means is as much what it means to others as what it means to the author; and indeed, in the course of time a poet may become merely reader in respect to his own works, forgetting his original meaning.
The definition of good prose is proper words in their proper places; of good verse, the most proper words in their proper places.The propriety is in either case relative. The words in prose ought to express the intended meaning, and no more; if they attract attention to themselves, it is, in general, a fault.
The poet's mind is in fact a receptacle for seizing and storing up numberless feelings, phrases, images, which remain there until all the particles which can unite to form a new compound are present together.
The philosophic mind inclines always to an elaborate life--the life of Goethe or of Leonardo da Vinci; but the life of the poet isintense--the life of Blake or of Dante--taking into its centre the life that surrounds it and flinging it abroad again amid planetary music.
A poet is a bird of unearthly excellence, who escapes from his celestial realm arrives in this world warbling. If we do not cherish him, he spreads his wings and flies back into his homeland.
Poetry may make us from time to time a little more aware of the deeper, unnamed feelings which form the substratum of our being, to which we rarely penetrate; for our lives are mostly a constant evasion of ourselves.
Not only every great poet, but every genuine, but lesser poet, fulfils once for all some possibility of language, and so leaves one possibility less for his successors.
