Poetry is the most direct and simple means of expressing oneself in words: the most primitive nations have poetry, but only quitewell developed civilizations can produce good prose. So don't think of poetry as a perverse and unnatural way of distorting ordinary prose statements: prose is a much less natural way of speaking than poetry is. If you listen to small children, and to the amount of chanting and singsong in their speech, you'll see what I mean.
