Fall; or, Dodge in Hell - Neal Stephenson Page 0,13

how many more times in his life he would see the leaves turn. Twenty or thirty? Not a super-large number. One of the Furious Muses was pointing out to him that the smallness of this figure should drive him to appreciate the beauty more than he was doing. That didn’t seem to work, but he had to admit that the glorious colors were made even more impressive by the current Pompitus Bombasticus selection.

What pathways in the brain, he wondered, connected these patterns of sound to pleasure? And were they intrinsic to the working of the mind or just an accident of evolution? Or to ask the same question another way, if there was an afterlife, either old-school analog or newfangled digital—if we lived on as spirits or were reconstituted as digital simulations of our own brains—would we still like music?

It hadn’t exactly rained, but the walk was wet anyway, with moisture that had condensed from the atmosphere. Red leaves were plastered to it, as if the place had been overrun by patriotic Canadians. The ones underfoot had gone a little dark, but when he gazed down the length of Cherry Street, the trees lining it had a Canadian-flag purity and intensity of redness no less than that of the traffic lights suspended above major intersections.

Corvallis Kawasaki had told him that there was a word for this: “quale.” The subjective experience of (for example) redness. Or of music, or of a tarte tatin. Neurologists and philosophers both wrote of qualia, tried to puzzle out what they were exactly, how you got them, whether they were intrinsic to consciousness. Did the ants feeding on a puddle of spilled soda experience its sweetness? Or were they too simple for that and only responding programmatically? The infrared sensor on an elevator door did not experience qualia of people stepping through its beam; it was just a dumb switch. Where on the evolutionary ladder did the brain stop being a glorified elevator door sensor and begin to experience qualia? Before or after ants? Or was it the case that an individual ant was too simple to experience qualia but a whole swarm of them collectively did?

All of these lofty considerations aside, Richard enjoyed qualia to a degree that bordered on the sexual. He had ruined more than one first date by reacting to a swallow of wine or a bite of steak in a manner that the woman across the table seemed to find a little creepy. A few years earlier, he had passed through a sort of prolonged near-death experience during which he’d had way too much time to think about this. He had even drawn up a list of good ones, as if cataloging them would lead to mastery, or at least understanding:

The black sheen of an old cast-iron griddle, its oily smell when heated.

The pucker in the back of a man’s powder-blue dress shirt.

The smell of a cedar plank fractured along a grain line.

Sparks of sunlight reflecting from waves.

The shape of the letter P.

Finding your exact location on a map.

Shortening your stride as you approached a curb.

Moving around in a house—walls you can’t pass through, doors you can.

Remaining upright. Balance. Standing on one foot.

Bubbles on the bottom of a pan getting ready to boil.

Having an appetite.

Just having been hit on the nose.

The opening strains of “Comfortably Numb.”

So much for the poet in him; the tech magnate idly wondered about all of the processing power that was being consumed by his brain, even in its most idle moments, simply taking in qualia and organizing them into a coherent story about the world and his place in it.

He snatched a particularly brilliant red maple leaf right out of the air and let it plaster its wet anatomy to the palm of his hand. He looked at it the way he might’ve as a kid looking at just such a leaf on a farm in Iowa. An observer at a distance would assume he was looking at his phone. There was something almost sinister about its symmetry, which was far from perfect and yet obvious and undeniable. Dark veins forked away from its spine. On its back surface, they stood out, like girders under a roof. On the front, each vein was a channel grooved into the red flesh, draining it like a system of rills and creeks and rivers, or feeding it like capillaries in an organ. It was a little triumph of spatial organization, like the state of Iowa, replicated millions of times
