"I think that books lacking such an introduction are like houses that one enters directly from the street, still wearing one's shoes and galoshes, still wrapped in the mood of outdoors. But an introduction to a volume of poetry functions like the anteroom to a house, a vestibule where one may shake off the burden of daily routine, where one may take off one's coat and boots, catch one's breath, pause for a minute to absorb the atmosphere of the dwelling one is about to enter."
