See: "The Best Way Out Is Through," editorial published in The New York Times, June 8, 2008.
p.s. (June 29, 2008): Based on the above, I ordered the book, and after a quick skim of Why Poetry Matters, I find no mention of Geoffrey Hill. Does this mean that Hill does not matter to Parini? Probably not, since he's been tagged in his "Poetry Hut Blog" (latest entry tagged, a link to William Logan's Review of A Treatise of Civil Power, blog entry from January 20, 2008), though my guess is that in this book which boasts it uses no jargon, Heaney seems more user-friendly. Why is it that Hill's closeness to the people and to popular culture always seems to be ignored?
Parini reviewed Robert Lowell: Collected Poems for the Guardian (August 9, 2003).http://books.guardian.co.uk/reviews/poetry/0,6121,1014876,00.html
