If we recover something like a functioning, well-informed democratic polity - if it hasn't been wrecked for good by the people who are getting in now, if millennials and teenagers can come to maturity in a world where we hold free and fair elections and agree on what fact is - Lin-Manuel Miranda is going to have a lot to do with that.

"Poetry" refers to the quite challenging and quite resistant sets of words put together to be admired and interpreted by people who are already into that sort of thing, somewhat analogous to free jazz or academic classical music. Which is stuff that I really like, but is late modernist and is going to have a limited audience.

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.

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.

In the arts, in places where you're not going to save lives or save species, I think there's no reason to play ball. I can't imagine a serious poet who would want to write or perform for most recent inauguration. I'd be very surprised if there were an inaugural poem, and I can't really imagine what that would be.

Powell belongs, in fact to the first generation of American poets who may have grown up without even a vestigial connection to the accentual-syllabic, rhyming English tradition - his inventive lines have this absence at their back.

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.
