Harry Potter And The Methods Of Rationality

Chapter 65: Contagious Lies

Hermione Granger had read somewhere once, that one of the keys to staying thin was to pay attention to the food you ate, to notice yourself eating it, so that you were satisfied with the meal. This morning she'd made herself toast, and put butter on the toast, and cinnamon on the butter, and it really should've been enough to get her to notice, this time, the goodness that was in front of her...

Without noticing the cinnamon or the butter, without noticing the food or that she was eating, Hermione swallowed another bite of toast, and said, "Can you try explaining that again? I'm still completely flabbergasted."

"It's pretty straightforward, if you think like a Light-Side Slytherin," said the boy that everyone else in school, excepting only the two of them, now believed to be her true love. Harry Potter's spoon absentmindedly stirred his breakfast cereal; he hadn't taken many bites of it this morning, not that Hermione had seen. "Every good thing in the world brings its own opposition into existence. Phoenixes are no exception."

Hermione took another unnoticed bite out of her buttered and cinnamoned toast, and said, "How can anyone not understand that Fawkes thinks you're a good enough person to ride around on your shoulder? He wouldn't do that with a Dark Wizard! He just wouldn't!"

And she hadn't yelled at anyone about Fawkes's touch on her own cheek, because she knew it wouldn't be right - that if a phoenix touched you, you weren't supposed to brag about it, that wasn't what a phoenix was for.

But she'd really hoped that it would squash the rumors about Harry Potter going evil and Hermione Granger following him down.

And it hadn't.

And she truly couldn't understand why not.

Harry ate another bite of his cereal, his eyes going distant now, no longer meeting her own. "Think of it this way: You skip school one day, and you lie and tell your teacher you were sick. The teacher tells you to bring a doctor's note, so you forge one. The teacher says she's going to call the doctor to check, so you have to give her a fake number for the doctor, and get a friend to pretend to be the doctor when she calls -"

"You did what? "

Harry looked up from his cereal then, and now he was smiling. "I'm not saying I really did that, Hermione..." Then his eyes abruptly dropped back down to his cereal. "No. Just an example. Lies propagate, that's what I'm saying. You've got to tell more lies to cover them up, lie about every fact that's connected to the first lie. And if you kept on lying, and you kept on trying to cover it up, sooner or later you'd even have to start lying about the general laws of thought. Like, someone is selling you some kind of alternative medicine that doesn't work, and any double-blind experimental study will confirm that it doesn't work. So if someone wants to go on defending the lie, they've got to get you to disbelieve in the experimental method. Like, the experimental method is just for merely scientific kinds of medicine, not amazing alternative medicine like theirs. Or a good and virtuous person should believe as strongly as they can, no matter what the evidence says. Or truth doesn't exist and there's no such thing as objective reality. A lot of common wisdom like that isn't just mistaken, it's anti-epistemology, it's systematically wrong. Every rule of rationality that tells you how to find the truth, there's someone out there who needs you to believe the opposite. If you once tell a lie, the truth is ever after your enemy; and there's a lot of people out there telling lies -" Harry's voice stopped.
