Around the same time, as I began to regain my sense of balance, I reread the work of my friend and mentor Amy Krouse Rosenthal, who’d died a few months earlier. She’d once written, “For anyone trying to discern what to do w/ their life: PAY ATTENTION TO WHAT YOU PAY ATTENTION TO. That’s pretty much all the info u need.” My attention had become so fractured, and my world had become so loud, that I wasn’t paying attention to what I was paying attention to. But when I put myself into the reviews as Sarah suggested, I felt like for the first time in years, I was at least trying to pay attention to what I pay attention to.

This book started out as a podcast, where I tried to chart some of the contradictions of human life as I experience it—how we can be so compassionate and so cruel, so persistent and so quick to despair. Above all, I wanted to understand the contradiction of human power: We are at once far too powerful and not nearly powerful enough. We are powerful enough to radically reshape Earth’s climate and biodiversity, but not powerful enough to choose how we reshape them. We are so powerful that we have escaped our planet’s atmosphere. But we are not powerful enough to save those we love from suffering.

I also wanted to write about some of the places where my small life runs into the large forces of the Anthropocene. In early 2020, after two years of writing the podcast, an exceptionally large force appeared in the form of a novel coronavirus. I began then to write about the only thing I could write about. Amid the crisis—and writing to you from April of 2021, I am still amid it—I find much to fear and lament. But I also see humans working together to share and distribute what we collectively learn, and I see people working together to care for the sick and vulnerable. Even separated, we are bound up in each other. As Sarah told me, there are no observers; only participants.

At the end of his life, the great picture book author and illustrator Maurice Sendak said on the NPR show Fresh Air, “I cry a lot because I miss people. I cry a lot because they die, and I can’t stop them. They leave me, and I love them more.”

He said, “I’m finding out as I’m aging that I’m in love with the world.”

It has taken me all my life up to now to fall in love with the world, but I’ve started to feel it the last couple of years. To fall in love with the world isn’t to ignore or overlook suffering, both human and otherwise. For me anyway, to fall in love with the world is to look up at the night sky and feel your mind swim before the beauty and the distance of the stars. It is to hold your children while they cry, to watch as the sycamore trees leaf out in June. When my breastbone starts to hurt, and my throat tightens, and tears well in my eyes, I want to look away from feeling. I want to deflect with irony, or anything else that will keep me from feeling directly. We all know how loving ends. But I want to fall in love with the world anyway, to let it crack me open. I want to feel what there is to feel while I am here.
