In the 1970s, for example, I found myself learning to relish the poetry of Andrew Marvell and Sir Thomas Wyatt, and getting a handle on poetry of plainer speech than I had dwelt with heretofore. Which led me into a new appreciation of middle [William Butler ] Yeats, of the short three-beat line and forward-driving syntax, and that paid in, in turn, to a poem like Casualty in Field Work. The traffic, however, was usually the other way. My teaching was animated by what I was reading and being excited by as a poet.
