Josephine Hart states in an interview.
Poetry is the highest form of language beyond any doubt, higher than novels, higher than drama because in terms of language, the poet finds the perfect word to express emotion or wisdom and in doing so he also has a musical sense in which each word is in its perfect place. Poetry is a trinity of sound and sense and sensibility. And the sound of sense, as Robert Frost said, and the sense of sound will be lost unless you hear it. It’s language caught alive!
