"There are basically three kinds of poetry: first, poetry which is divine (inspired); secondly, poetry which is crafted; and thirdly, poetry which is inherited. It reminds me of Gerard Manley Hopkins. He has a letter to a friend of his in which he speaks of writing and how there are three voices of the poet: the Olympian (inspired); the Parnassian (when you're really a good poet, you don't write bad poetry but sometimes you write so-so poetry), and finally, there's jargon."
