To posit that wisdom is only acquired by sitting in a college classroom discounts the wisdom of most people in history. One wonders how wise King Solomon could have become if only he had taken a modern free-form art, a Chicano culture studies or a slam poetry class at Evergreen College. Just think of the great works Mozart might have produced had his parents the forethought to enroll him in a watercolor painting class at the local community college. And then there are the millions of wise people through the thousands of years who never attended college and whose names will never be known.
While poetry may be an art form, it's practice is largely a hobby, just as one would expect to be the outcome of the other curiccula mentioned above. Your assertion about the relationship between art and truth is an unfounded opinion. A certain amount of navel-gazing is understandable, but one has to eat.
A parade of straw men. Boring. Got anything else?
