The history of American poetry, like the history of America itself, is a story of ingenuity, sacrifice, hard work and sticking it to people when they least expect it. Whether it’s Ezra Pound dismissing his benefactor Amy Lowell as a “hippopoetess” or Yvor Winters accusing his friend Hart Crane of possessing flaws akin to a “public catastrophe,” you can count on the occasional bushwhacking in the land of what Horace called “the touchy tribe.” The most recent such assault — and the most surprising in years — took the form of a 6,500-word article in The New Yorker last month by the poet Dana Goodyear, who is also a New Yorker editor.
