Shatner, Dante, and the overview effect

In his recently released memoir, William Shatner recounts the unexpected emotional experience of going to space and seeing Earth:

I thought that going into space would be the ultimate catharsis of that connection I had been looking for between all living things—that being up there would be the next beautiful step to understanding the harmony of the universe. In the film “Contact,” when Jodie Foster’s character goes to space and looks out into the heavens, she lets out an astonished whisper, “They should’ve sent a poet.” I had a different experience, because I discovered that the beauty isn’t out there, it’s down here, with all of us. Leaving that behind made my connection to our tiny planet even more profound.

It was among the strongest feelings of grief I have ever encountered. . . . It filled me with dread. My trip to space was supposed to be a celebration; instead, it felt like a funeral.

Later, he writes, he learned that this profound feeling was his experience of the “overview effect,” something commonly felt by astronauts. As summarized by NPR: “The overview effect is a cognitive and emotional shift in a person's awareness, their consciousness and their identity when they see the Earth from space.” Smallness, delicacy, beauty—the overview effect, per its name, gives perspective to a place too big to comprehend in ordinary life.

As is my wont, I immediately thought of Dante, who describes precisely this effect in Canto 22 of Paradiso. Flying through the highest reaches of the heavens with Beatrice, she tells him to look down.

My eyes returned through all the seven spheres
and saw this globe in such a way that I
smiled at its scrawny image: . . .
I saw Latona’s daughter radiant,
without the shadow that had made me once
believe that she contained both rare and dense.
And there, Hyperion, I could sustain
the vision of your son, and saw Dione
and Maia as they circled nearby him.
The temperate Jupiter appeared to me
between his father and his son; and I
saw clearly how they vary their positions.
And all the seven heavens showed to me
their magnitudes, their speeds, the distances
of each from each. The little threshing floor
that so incites our savagery was all—
from hills to river mouths—revealed to me
while I wheeled with eternal Gemini.

This is not only Earth but the entire solar system, from moon (“Latona’s daughter”) to Saturn (Jupiter’s father), and Dante—working purely from imagination six hundred years before the advent of space travel—correctly predicts the shrinking and sharpening perspective that a sight of Earth as a tiny blue orb between his feet would impart. All “our savagery” plays out in nothing but a “little threshing floor.”

“Everyone's overview effect is unique to them,” according to NPR, and Shatner’s, sadly, is a formulaic mélange of environmental admonitions and therapeutic bromides:

The contrast between the vicious coldness of space and the warm nurturing of Earth below filled me with overwhelming sadness. Every day, we are confronted with the knowledge of further destruction of Earth at our hands: the extinction of animal species, of flora and fauna . . . things that took five billion years to evolve, and suddenly we will never see them again because of the interference of mankind. . . .

[The overview effect] can change the way we look at the planet but also other things like countries, ethnicities, religions; it can prompt an instant reevaluation of our shared harmony and a shift in focus to all the wonderful things we have in common instead of what makes us different. It reinforced tenfold my own view on the power of our beautiful, mysterious collective human entanglement, and eventually, it returned a feeling of hope to my heart. In this insignificance we share, we have one gift that other species perhaps do not: we are aware—not only of our insignificance, but the grandeur around us that makes us insignificant. That allows us perhaps a chance to rededicate ourselves to our planet, to each other, to life and love all around us. If we seize that chance.

Dante, by contrast, has no call to action, no language of collectives or harmony or nurturing or “human entanglement” or false humility about “our planet.” He offers pure, unflinching perspective. Confronted with the Earth in all its smallness, Dante

smiled at scrawny image: I approve
that judgment as the best, which holds this earth
to be the least; and he whose thoughts are set
elsewhere, can truly be called virtuous.

Real hope begins with a properly oriented overview effect—it should begin with not only a sense of physical, planetary scale but of eternal perspective, so that even the things Shatner both laments and praises will be seen in their true smallness.

NPR talked to him and got more disappointing soundbites, with outside commentary by the man who coined the term “overview effect,” all of which you can read here. The translation of Paradiso XXII is that of Allen Mandelbaum; you can read the whole thing at Columbia’s Digital Dante.
