Eliezer Yudkowsky - Harry Potter and the Methods of Rationality

Harry couldn't help himself. He looked over again, despite knowing it would be futile, and saw only more stars. "Let me guess, from this you deduce that... people don't actually care as much about their friends as they pretend."

A brief laugh. "They would scarcely pretend to care less ."

"They care, Professor, and not just for their true loves. Soldiers throw themselves on grenades to save their friends, mothers run into burning houses to save their children. But if you're a Muggle you don't think there's any such thing as magic to bring someone back to life. And normal wizards don't... think outside the box like that. I mean, most wizards aren't searching for power to make themselves immortal. Does that prove they don't care about their own lives?"

"As you say, Mr. Potter. Certainly I myself would consider their lives pointless and without a shred of value. Perhaps, somewhere in their hidden hearts, they also believe that my opinion of them is the correct one."

Harry shook his head, and then, in annoyance, cast back the hood of his Cloak, and shook his head again. "That seems like a rather contrived view of the world, Professor," said the dim-lit head of a boy, floating unsupported on a circle of dark grass amid stars. "Trying to invent a resurrection spell just isn't something normal people would think of, so you can't deduce anything from their not taking the option."

A moment later, the dim-lit outline of a man sitting on the circle of grass was visible as well.

"If they truly cared about their supposed loved ones," the Defense Professor said softly, "they would think of it, would they not?"

"Brains don't work that way. They don't suddenly supercharge when the stakes go up - or when they do, it's within hard limits. I couldn't calculate the thousandth digit of pi if someone's life depended on it."

The dim-lit head inclined. "But there is another possible explanation, Mr. Potter. It is that people play the role of friendship. They do just as much as that role requires of them, and no more. The thought occurs to me that perhaps the difference between you and them is not that you care more than they do. Why would you have been born with such unusually strong emotions of friendship, that you alone among wizardkind are driven to resurrect Hermione Granger after her death? No, the most likely difference is not that you care more. It is that, being a more logical creature than they, you alone have thought that playing the role of Friend would require this of you."

Harry stared out at the stars. He would have been lying if he'd claimed not to be shaken. "That... can't be true, Professor. I could name a dozen examples in Muggle novels of people driven to resurrect their dead friends. The authors of those stories clearly understood exactly how I feel about Hermione. Though you wouldn't have read them, I guess... maybe Orpheus and Eurydice? I didn't actually read that one but I know what's in it."

"Such tales are also told among wizardkind. There is the story of the Elric brothers. The tale of Dora Kent, who was protected by her son Saul. There is Ronald Mallett and his doomed challenge to Time. In Italy before its fall, the drama of Precia Testarossa. In Nippon they tell of Akemi Homura and her lost love. What these stories have in common, Mr. Potter, is that they are all fiction. Real-life wizards do not attempt the same, even though the notion is clearly not beyond their imagination."

"Because they don't think they can! " Harry's voice rose.

"Shall we go and tell the good Professor McGonagall about your intention to find a way to resurrect Miss Granger, and see what she thinks of it? Perhaps it has simply never occurred to her to consider that option... Ah, but you hesitate. You already know her answer, Mr. Potter. Do you know why you know it?" You could hear the cold smile in the voice. "A lovely technique, that. Thank you for teaching it to me."

Harry was aware of the tension that had developed in his face, his words came out as though bitten off. "Professor McGonagall has not grown up with the Muggle concept of the increasing power of science, and nobody's ever told her that when a friend's life is at stake is a time when you need to think very rationally -"

The Defense Professor's voice was also rising. "The Transfiguration Professor is reading from a script, Mr. Potter! That script calls for her to mourn and grieve, that all may know how much she cared. Ordinary people react poorly if you suggest that they go off-script. As you already knew!"

"That's funny, I could have sworn I saw Professor McGonagall going off-script at dinner yesterday. If I saw her go off-script another ten times I might actually try to talk to her about resurrecting Hermione, but right now she's new to that and needs practice. In the end, Professor, what you're trying to explain away by calling love and friendship and everything else a lie is just human beings not knowing any better. "

The Defense Professor's voice rose in pitch. "If it were you who had been killed by that troll, it would not even occur to Hermione Granger to do as you are doing for her! It would not occur to Draco Malfoy, nor to Neville Longbottom, nor to McGonagall or any of your precious friends! There is not one person in this world who would return to you the care that you are showing her! So why? Why do it, Mr. Potter?" There was a strange, wild desperation in that voice. "Why be the only one in the world who goes to such lengths to keep up the pretense, when none of them will ever do the same for you?"

"I believe you are factually mistaken, Professor," Harry returned evenly. "About a number of things, in fact. At the very least, your model of my emotions is flawed. Because you don't understand me the tiniest bit, if you think that it would stop me if everything you said was true. Everything in the world has to start somewhere, every event has to happen for a first time. Life on Earth had to start with some little self-replicating molecule in a pool of mud. And if I were the first person in the world, no -"

Harry's hand swept out, to indicate the terribly distant points of light.

"- if I were the first person in the universe who ever really cared about someone else, which I'm not by the way, then I'd be honored to be that person, and I'd try to do it justice."

There was a long silence.

"You truly do care about that girl," the man's dim outline said softly. "You care about her in the way that none of them are capable of caring for their own lives, let alone each other." The Defense Professor's voice had become strange, filled with some indecipherable emotion. "I do not understand it, but I know the lengths you will go to because of it. You will challenge death itself, for her. Nothing will sway you from that."

"I care enough to make an actual effort," Harry said quietly. "Yes, that is correct."

The starlight slowly began to fracture, the world shining through the cracks; slashes through the night showing treetrunks and leaves glowing in the sunlight. Harry raised a hand, blinking hard, as the returning brightness smashed into his dark-adjusted eyes; and his eyes automatically went to the Defense Professor, just in case an attack occurred while he was blinded.

When all the stars had gone and only daylight remained, Professor Quirrell was still sitting on the grass. "Well, Mr. Potter," he said in his normal voice, "if that is so, then I shall give you what help I can, while I can."

"You'll what? " Harry said involuntarily.

"My offer as I made it yesterday still stands. Ask and I will answer. Show me the same science books you deemed suitable for Mr. Malfoy, and I shall look them over and tell you what comes to mind. Don't look so surprised, Mr. Potter, I would hardly leave you to your own devices."
