I believe structure is necessary because structure and creativity have the same parentage. It is structure that enables creativity. We see examples of this everywhere. In nature, we see the fantastic diversity generated by a few basic structural elements: no more than a hundred varieties of atoms and a couple of primary colors, lead to a universe of infinite beauty and diversity. In the great human creations, in the twelve notes of the musical scale, in the twenty six letters of the alphabet, these fantastic structural inventions have unlocked the enormous creativity of literature and music. Without structure, there is nothing for creativity to get leverage upon.
