Exact science and its practical movements are no checks on the greatest poet, but always his encouragement and support ... The sailor and traveller, the anatomist, chemist, astronomer, geologist, phrenologist, spiritualist, mathematician, historian and lexicographer are not poets, but they are the lawgivers of poets and their construction underlies the structure of every perfect poem.
Orpheus with his lute made trees, And the mountain tops that freeze, Bow themselves, when he did sing; To his music, plants and flowers Ever sprung; as sun and showers There had made a lasting spring. Every thing that heard him play, Even the billows of the sea, Hung their heads, and then lay by. In sweet music is such art, Killing care and grief of heart Fall asleep, or hearing, die.
