I was talking to a friend who was feeling down about human-caused global climate change. “It may be,” I told a friend in London as we walked across Tower Bridge, “that our ticket was punched before we ever got started.” While there is no doubt we’re cutting our time on earth shorter through carbon emissions and the destruction of the ecology, it might be that our species was never going to make it past the end of the womb of our ice-age birth. I explained this, about how fragile an organism we are, and how the ice ages cycle. She laughed, she was used to my strange form of hope.

“You have to choose to have hope, or just jump out of a window,” a person I was interviewing once told me, a person who’d been accused of techno-utopianism. We were walking along the California coast hills at sunset, talking about all the ways our technological lives could go wrong, and the many ways it is going wrong. He wasn’t utopian, it turned out, he’d thought of the worst long before his detractors had. He’d decided to try to head it off, instead of jumping out of a window.

We are diseased and angry and we kill each other and ourselves and all the world. We are killing off life on Earth like a slow moving asteroid. I try to look at this, and my own part in it. Sometimes it is overwhelming. I feel so powerless trying to comprehend all the terrible things we face, much less get past them into our future, with our humanity and our inconceivably beautiful little blue-green planet preserved.

All these grown-up monsters for my grown-up mind, they are there in the nights I wake up terrified and taunted by death. When I feel so small and broken, when despair and terror take me, I have a secret tool, a talisman against the night. I don’t use it too often so that it doesn’t lose its power. I learned it on airplanes, which are strange and thrilling and full of fear and boredom and discomfort. When I am very frightened, I look out the window on airplanes and say very quietly:

I have seen the tops of clouds

And I have. In all the history of humanity, I am one of the few that has seen the tops of clouds. Many would have died to do so, and some did. I have seen them many times. I have seen the Earth from space, and spun it around like a god to see what’s on the other side. We are the only consciousness we’ve ever found that has looked deep into the infinite dark, and instead of dark, we saw galaxies. Galaxies! Suns and worlds beyond number. We have looked into our world and found atoms, atomic forces, systems that dance to the glorious music of the universe. We have seen actual wonders that verge on the ineffable. We have coined a word for the ineffable. We have coined thousands of words for the ineffable. In our pain we find a kind of magic, in our worst and meanest specimens we find the flesh of a common human story. We are red with it.

I know mysteries that great philosophers would have died for, just to have them whispered in their dying ears. I can look them up on my smartphone. I live in the middle of miracles, conceptions and magics easily worth many lifetimes to learn, from which I can pick and choose. I have wisdom and knowledge poured around me like a river, more than I could learn in a thousand lifetimes, and I am still alive. It is good that I am alive, it is good that we are alive. Even if we kill ourselves off with nuclear fire, or gray goo, or drown ourselves in stinking acid oceans, it is good that we have lived, that we did all of this, and that we grew into what we are, and learned to dream of what we could be. The only thing we can say for sure is that we will die, but we will die having gone so far above our primordial ponds and primate forests that we saw the tops of clouds.
