all the light we cannot see

 

Mycena Subcyanocephala fungi - ‘blue head’ - a single millimeter tall

We all come into existence as a single cell, smaller than a speck of dust. Much smaller. Divide. Multiply. Add and subtract. Matter changes hands, atoms flow in and out, molecules pivot, proteins stitch together, mitochondria send out their oxidative dictates; we begin as a microscopic electrical swarm. The lungs the brain the heart. Forty weeks later, six trillion cells get crushed in the vise of our mother’s birth canal and we howl. Then the world starts in on us.

One night Werner and Jutta tune in to a scratchy broadcast in which a young man is talking in feathery, accented French about light. The brain is locked in total darkness, of course, children, says the voice. It floats in a clear liquid inside the skull, never in the light. And yet the world it constructs in the mind is full of light. It brims with color and movement. So how, children, does the brain, which lives without a spark of light, build for us a world full of light? The broadcast hisses and pops. “What is this?” whispers Jutta.

Werner does not answer. The Frenchman’s voice is velvet. His accent is very different from Frau Elena’s, and yet his voice is so ardent, so hypnotizing, that Werner finds he can understand every word. The Frenchman talks about optical illusions, electromagnetism; there’s a pause and a peal of static, as though a record is being flipped, and then he enthuses about coal. 

Consider a single piece glowing in your family’s stove. See it, children? That chunk of coal was once a green plant, a fern or reed that lived one million years ago, or maybe two million, or maybe one hundred million. Can you imagine one hundred million years? Every summer for the whole life of that plant, its leaves caught what light they could and transformed the sun’s energy into itself. Into bark, twigs, stems. Because plants eat light, in much the way we eat food. But then the plant died and fell, probably into water, and decayed into peat, and the peat was folded inside the earth for years upon years—eons in which something like a month or a decade or even your whole life was just a puff of air, a snap of two fingers.

[…]

Open your eyes, concludes the man, and see what you can with them before they close forever, and then a piano comes on, playing a lonely song that sounds to Werner like a golden boat traveling a dark river, a progression of harmonies that transfigures Zollverein: the houses turned to mist, the mines filled in, the smokestacks fallen, an ancient sea spilling through the streets, and the air streaming with possibility.

All the Light We Cannot See

.

Imagine the most extreme example, a human being who does not possess the power to forget, who is damned to see becoming everywhere; such a human being would no longer believe in his own being, would no longer believe in himself, would see everything flow apart in turbulent particles, and would lose himself in this stream of becoming; like the true student of Heraclitus, in the end he would hardly even dare to lift a finger. 

All action requires forgetting, just as the existence of all organic things requires not only light, but darkness as well.

—Rodrigo Quian Quiroga
