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.

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.

One chance, One life. Make it or screw it up, it's your choice. Don't wait to long or your time will be up.

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.
