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.
