For though we often need to be restored to the small, concrete, limited, and certain, we as often need to be reminded of the large, vague, unlimited, unknown
If we ask a vague question, such as, 'What is poetry?' we expect a vague answer, such as, 'Poetry is the music of words,' or 'Poetry is the linguistic correction of disorder.'
I can't tell you where a poem comes from, what it is, or what it is for: nor can any other man. The reason I can't tell you is that the purpose of a poem is to go past telling, to be recognised by burning.
Even if you walk exactly the same route each time - as with a sonnet - the events along the route cannot be imagined to be the same from day to day, as the poet's health, sight, his anticipations, moods, fears, thoughts cannot be the same.
With the first step, the number of shapes the walk might take is infinite, but then the walk begins to define itself as it goes along, though freedom remains total with each step: any tempting side road can be turned into an impulse, or any wild patch of woods can be explored. The pattern of the walk is to come true, is to be recognized, discovered.
Poetry leads us to the unstructured sources of our beings, to the unknown, and returns us to our rational, structured selves refreshed. Having once experienced the mystery, plenitude, contradiction, and composure of a work of art, we afterward have a built-in resistance to the slogans and propaganda of oversimplification that have often contributed to the destruction of human life. Poetry is a verbal means to a nonverbal source. It is a motion to no-motion, to the still point of contemplation and deep realization.
