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.
Pretty conceptions, fine metaphors, glittering expressions, and something of a neat cast of verse are properly the dress, gems, or loose ornaments of poetry.
for a poet is a light and winged thing, and holy, and never able to compose until he has become inspired, and is beside himself, and reason is no longer in him.
Therefore we value the poet. All the argument and all the wisdom is not in the encyclopedia, or the treatise on metaphysics, or the Body of Divinity, but in the sonnet or the play.
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 word "Verse" is used here as the term most convenient for expressing, and without pedantry, all that is involved in the consideration of rhythm, rhyme, meter, and versification... the subject is exceedingly simple; one tenth of it, possibly may be called ethical; nine tenths, however, appertains to the mathematics.
