In pursuing certain virtues - colorful local effects, personae and personality, juxtaposition, close calls with nonsense, uncertainty, critiques of ordinary language - the current crop of American poets necessarily give up on others.

Gunn would be an important figure-rewarding, delightful, accomplished, enduring-in the history of English-language poetry even were his life not as fascinating as it now seems; he would be an important figure in the history of gay writing and in the history of transatlantic literary relations even were his poetry not so good as it is. With his life as it was and his works as they are, he's an obvious candidate for a volume of retrospective and critical essays, and this one is first-rate.

Some poets marry a language; some have affairs with it; some treat it as a parent, some as a child, some as an equal, or as a friend.

Durable, memorable poetry is usually alert to complexity. A really good poem gives you a reason to read it 20 times, because the language in a good poem is doing a lot of work emotionally and a lot of work intellectually. That means durable poetry can help us think about complexity, can help us resist easy answers and help us step back. And it can help us sometimes calm down, and sometimes it can help us stay upset.

Poetry can explain individuals to ourselves, and change our attitudes, and help us see the complexity of the world, but the kind of poetry I follow isn't going to change public opinion directly. Other art forms can - if you're a TV writer, you have some interesting challenges, or if you're a country musician, somebody like Brad Paisley. But poetry not so much.

Good poems do a lot of things at once. Often, by doing so, they encourage us to acknowledge mixed and incompatible feelings. Good poems, like good works of history, resist monocausal explanations for anything. There's not one reason why I am angry or excited or hopeful, when I feel those things. And there's not one reason why President Obama won two elections. And there's not one reason why Donald Trump won the most recent presidential election.
