Peter Watts - Echopraxia

And it came to pass that certain people figured out how to use that. They painted their faces or they wore funny hats, they shook their rattles and waved their crosses and they said, Yes, there are tigers in the grass, there are faces in the sky, and they will be very angry if you do not obey their commandments. You must make offerings to appease them, you must bring grain and gold and altar boys for our delectation or they will strike you down and send you to the Awful Place. And people believed them by the billions, because after all, they could see the invisible tigers.

And you’re a smart kid, Lianna. You’re a bright kid and I like you but some day you’ve got to grow up and realize that it’s all a trick. It’s all just eyes scribbled on the wall, to make you think there’s something looking back.

That’s what Brüks wanted to say. And Lianna would listen, and ponder this new information, and she would come to see the wisdom of his argument. She would change her mind.

The only problem with this scenario was that it rapidly became obvious that she already knew all that stuff, and believed in invisible tigers anyway. It drove him up the fucking wall.

“That’s not God, ” she said one morning in the Commons, wide eyed with astonishment that he could have made such a stupid mistake. “That’s just a bunch of ritualistic junk that got stuck onto God by people who wanted to hijack the agenda.”

A derisive snort from over by the galley dispenser. “Between you two arguing about ghosts and Carnage stringing out on rotten bits”—Sengupta grabbed her breakfast and headed for the ladder—“I don’t think I can handle five more minutes of this shit.”

Brüks watched her go, turned his attention to a bulkhead window Lianna had opened into the Hold: shadows, machine parts, weightless bodies drawing dismembered components together into tangled floating jigsaws. Binary stars, sparkling in the gloom.

“If it’s junk, why do they keep doing it?” He jerked his thumb at the display. “Why can’t those guys go thirty minutes without doing that hand-washing thing of theirs?”

“Hand-washing reduces doubt and second-guessing in the wake of making a decision,” Lianna told him. “Brains tend to take metaphors literally.”

“Bullshit.”

Her eyes defocused for an instant. “I’ve just sent you the citation. Of course an actual tweak would be more efficient—I bet they do that too, actually—but I think they like to remember where they came from. You’d be surprised how much folklore has survival value when you rip it up and look at the roots.”

“I never said religious beliefs weren’t adaptive . That doesn’t make them true.” Brüks spread his hands, palms up.

“What do you think vision is?” she asked him. “You don’t see a fraction of the things that surround you, and at least half the things you do see are wrong. Hell, color doesn’t even exist outside your own head. Vision’s just plain wrong ; it only persists because it works . If you’re going to dismiss the idea of God, you better stop believing your own eyes in the bargain.”

“My eyes never told me to murder anyone who doesn’t share my worldview.”

“My God never told me to do that either.”

“Lots of people’s Gods have.”

“Riiight. And we’re just gonna ignore all those racist assholes who quoted Darwin to justify turning people into slaves? Or wiping them out altogether?” He opened his mouth; she preempted him with a raised hand: “Let’s just agree that neither side has a monopoly on assholes. The point is, once you recognize that every human model of reality is fundamentally unreal, then it all just comes down to which one works best. And science has had a damn good run, no question. But the sun is setting on the Age of Empiricism.”

He snorted. “The Age of Empiricism is just getting started.”

“Come on, Oldschool. We’re long past the days when all you had to do was clock a falling apple or compare beak length in finches. Science has been running into limits ever since it started trying to get Schrödinger’s cat to play with balls of invisible string. Go down a few orders of mag and everything’s untestable conjecture again. Math and philosophy. You know as well as I do that reality has a substructure . Science can’t go there.”

“Nothing can. Faith may claim —”

“Knot theory,” Lianna said. “Invented it for the sheer beauty of the artifact. We didn’t have particle accelerators back then; we had no evidence at all that it would turn out to describe subatomic physics a century or two down the road. Pre-Socratic Greeks intuited atomic theory in two hundred B.C. Buddhists were saying centuries ago that we can’t trust our senses, that sensation itself is an act of faith. Hinduism’s predicated on the Self as illusion: no NMRs a thousand years ago, no voxel readers. No evidence . And damned if I can see the adaptive advantage of not believing in your own existence; but neurologically it happens to be true.”

She beamed at him with the beatific glow of the true convert. “There’s an intuition, Dan. It’s capricious, it’s unreliable, it’s corruptible—but it’s so powerful when it works, and it’s no coincidence that it ties into the same parts of the brain that give you the rapture. The Bicamerals harnessed it. They amped the temporal and they rewired the parietals—”

“You mean ripped them out completely.”

“—and they had to leave conventional language back in the dust, but they figured it out. Their religion, for want of a better word, goes places science can’t. Science backs it up, as far as science can go; there’s no reason to believe it doesn’t keep right on working after it leaves science behind.”

“You mean you have faith it keeps working,” Brüks observed drily.

“Do you measure Earth’s gravity every time you step outside? Do you reinvent quantum circuits from scratch whenever you boot up, just in case the other guys missed something?” She gave him a moment to answer. “Science depends on faith,” she continued, when he didn’t. “Faith that the rules haven’t changed, faith that the other guys got the measurements right. All science ever did was measure a teensy sliver of the universe and assume that everything else behaved the same way. But the whole exercise falls apart if the universe doesn’t follow consistent laws. How do you test if that’s true?”

“If two experiments yield different results—”

“Happens all the time, my friend. And when it does, every good scientist discounts those results because they failed to replicate . One of the experiments must have been flawed. Or they both were. Or there’s some unknown variable that’ll make everything balance out just as soon as we discover what it is. The idea that physics itself might be inconsistent? Even if you considered the possibility in your wildest dreams, how could you test for it when the scientific method only works in a consistent universe?”

He tried to think of an answer.

“We’ve always thought c and friends ruled supreme, right out to the quasars and beyond,” Lianna mused. “What if they’re just—you know, some kind of local ordinance? What if they’re a bug ? Anyway”—she fed her plate into the recycler—“I gotta go. We’re test-firing the chamber today.”

“Look, science—” He marshaled his thoughts, unwilling to let it go. “It’s not just that it works. We know how it works. There’s no secret to it. It makes sense .”
