Eliezer Yudkowsky - Harry Potter and the Methods of Rationality

"You've got to give them points too," said Ron Weasley from the Gryffindor table. "Or I won't take any."

"Who else?" said Professor McGonagall, her voice a bit unsteady.

Seven other children stood up.

What was that our Slytherin side was saying about predicting nothing would ever work? said Hufflepuff.

Something in Harry cracked, so that he had to exert all his force to hold himself together.

When all had been said, and all had been done, Minerva went to where Harry Potter stood. Though it was not her greatest skill she cast a ward about them to blur vision, and muffled sounds with another thought.

"You, you didn't have to -" said Harry Potter. "You shouldn't have said -" He sounded like he was choking. "P-Professor, everything I said to you was hurtful, and hateful, and wrong -"

"I already knew that, Harry," she said. "Even so, I wished to do better." There was a feeling of lightness in her chest, much as one might experience after stepping off a cliff, when your legs no longer had to hold your body upright. She wasn't sure she could do this, she did not know the way; and yet for the first time it seemed possible that Hogwarts wouldn't become a sad ghost of its former self, when she became its Headmistress.

Harry stared at her, then made a odd noise that sounded like it had been forced from his throat, and covered his face in his hands.

So she knelt down, and hugged him. It might go wrong, but it might also go right, and she would not let that uncertainty stop her; it was time she began to learn a Gryffindor's courage, so that she could teach it in turn.

"I had a sister once," she whispered. Just that, and nothing more.

Just to make sure, said some part of Harry, while the rest of him sobbed into Professor McGonagall's arms, this doesn't mean we've accepted Hermione's death, right?

NO said all the rest of him, every part of his mind in unanimous agreement, warmth and cold and a hidden place of steel. Never, ever, forever.

And an ancient wizard to whom that ward meant nothing gazed upon them both, the witch and the weeping young wizard. Albus Dumbledore was smiling with a strange sad look in his eyes, like someone who has taken one more step toward a foreseen destination.

The Defense Professor watched them both, the woman and the crying boy. His eyes were very cold, and very calculating.

He did not think that this would be enough.

It wasn't until the next morning that it was discovered that Hermione Granger's body was missing.

The first meeting:

At 6:07am on April 17th, 1992 the Sun was just rising above the horizon as seen from the castle Hogwarts, filtering in through drawn curtains in the Ravenclaw first-year boys' dorm to provide a gentle light, red-orange for dawn and little-changed by the white fabric covering the windows, not yet waking boys more accustomed to winter's schedule.

In one bed among many, Harry Potter slept the sleep of the just exhausted.

Quietly the door opened.

Quietly a figure walked across the floor.

That figure came to Harry Potter's bed.

The figure laid a hand on the shoulder of the sleeping boy, who started and shrieked.

No others heard.

"Mr. Potter," the small man squeaked, "the Headmaster has requested your presence immediately."

Slowly the boy sat up in bed, his hands momentarily fiddling beneath the covers. He'd expected to feel much worse, waking up this morning. It felt... wrong, that his brain functioned now, that his thoughts still moved, that he wasn't incapacitated with weeping for at least a week. The boy knew that it wouldn't have been an adaptive response, for brains to evolve to do that. His dark side, certainly, would not do that. Even so, it still felt wrong to be alive and lucid, this morning.

But his resolution to revive Hermione Granger felt - sufficient, like he was already doing the right thing, bent on the right path, and she would be brought back, and that was all there was to it; grief would have been giving up. There was nothing left to decide, no ambiguity, no conflict to tear at him, and no need to remember what he'd seen -

"I'll get dressed," Harry said.

Professor Flitwick looked rather reluctant, but said in his high voice, "The Headmaster specified you were to be brought to his office directly and without pause, Mr. Potter. I'm sorry."

Less than a minute later - Professor Flitwick had sent him straight to the Headmaster's office through the Hogwarts internal Floo - Harry found himself, still in his pajamas, facing Albus Dumbledore. The Deputy Headmistress was also sitting in another chair, and the Potions Master lurked nearby amid the weird devices, caught in a gaping yawn just as Harry had entered through the fireplace.

"Harry," the Headmaster said without preamble, "before I say what I must say next, I tell you that Hermione Granger did truly die. The wards recorded it and informed me. The very stones spoke that a witch had died. I tested her body where it lay and those were Hermione Granger's true mortal remains, not any doll or likeness. There is no way known to wizardry by which death may be undone. All this being said, Hermione Granger's remains are now missing from the storeroom where they were placed, and where you guarded them. Did you take them, Harry Potter?"

"No," Harry said, narrowing his eyes. A glance showed him that Severus was watching him intently.

Dumbledore's gaze was also keen, though not unfriendly. "Is Hermione Granger's body in your possession?"

"No."

"Do you know where it is?"

"No."

"Do you know who took it?"

"No," Harry said, then hesitated. "Besides the obvious probabilistic speculations which are not based upon any specific knowledge of mine."

The old wizard nodded. "Do you know why it was taken?"

"No. Besides the obvious speculations etcetera."

"What would those be?" Sharp the ancient eyes.

"If the enemy can notice you running off to consult the Weasley twins during class after Hermione was arrested, and find out about that magic map you said was stolen, then the enemy can wonder why I was guarding Hermione Granger's body. My turn. Did you arrange for Hermione's death in hopes of getting the money back from Lucius?"

" What? " said Professor McGonagall.

"No," said the old wizard.

"Did you know or suspect that Hermione Granger would die?"

"I did not know. As for suspicions, I placed her in the most strongly defended position I could, against Voldemort. I did not will her death, nor allow it, nor plan to benefit from it, Harry Potter. Now show me your pouch."

"It's in my trunk -" Harry began.

"Severus," said the old wizard, and the Potions Master moved forward. "Check his trunk as well, every compartment."

"My trunk has wards."

Severus Snape grinned mirthlessly and strode into the green flame.

Dumbledore took out his long dark-grey wand and began to wave it close around Harry's hair, looking like a Muggle using a metal-detector. Before he had reached as far as Harry's neck, Dumbledore stopped.

"The gem upon your ring," Dumbledore said. "It is no longer a clear diamond. It is brown, the color of Hermione Granger's eyes, and the color of her hair."

A sudden tension filled the room.

"That's my father's rock," Harry said. "Transfigured the same as before. I just did it to remember Hermione -"

"I must be sure. Take off that ring, Harry, and place it upon my desk."

Slowly, Harry did so, removing the gem and setting the ring off to the other side of the desk.

Dumbledore pointed his wand at the gem and -

A large, undistinguished grey rock jumped into the air from the force of its sudden expansion, hit some invisible barrier in the air above, and then fell with a loud crack upon the Headmaster's desk,
