The city sleeps and the country sleeps, the living sleep for their time, the dead sleep for their time, the old husband sleeps by his wife and the young husband sleeps by his wife; and these tend inward to me, and I tend outward to them, and such as it is to be of these more or less I am, and of these one and all I weave the song of myself.
Walt WhitmanExact 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.
Walt Whitman
