Form is generative; it is the very source of creation. Wendell Berry comments on the power of verse form to help us better see:
One of the great practical uses of literary disciplines… is to resist glibness – to slow language down and make it thoughtful. This accounts for the influence of verse, it its formal aspect, within the dynamics of the growth of language: verse checks the merely impulsive flow of speech, subjects it to another pulse, to measure, to extra-linguistic considerations; by inducing the hesitations of difficulty, it admits into language the influence of the Muse and of musing.”
