Harry Potter and the Methods of Rationality

Fawkes above them all. A calm, warm room of bright stone columns, skylit on all four sides, populated by white beds in long rows, four of which had silencing veils drawn around them, and the rest empty.

In one corner of Harry's vision, a surprised-looking Madam Pomfrey was turning toward them. Dumbledore seemed to pay the senior healer no heed, as he carefully laid down Hermione on an unoccupied white bed.

From a distant corner there was a flash of green, and from out of a fireplace strode Professor McGonagall, brushing herself off slightly from the Floo ashes.

The old wizard turned from the bed and reached one of his arms around Harry again; and then the Boy-Who- Lived and his wizard vanished in another burst of fire.

When Harry had fully lit up again he was standing in the Headmaster's office, amid the noises of a dozen dozen inexplicable gidgets.

The young boy took a step away from the old wizard and then turned on him, emerald and sapphire eyes meeting.

The two of them did not speak for a time, looking at each other; as though all they had to speak could be said only by stares, and not said in any other way.

In time the boy enunciated words slowly and precisely.

"I cannot believe that a phoenix is still upon your shoulder."

"The phoenix chooses but once," said the old wizard. "They might perhaps leave a master who chooses evil over good; they will not leave a master forced to choose between one good and another. Phoenixes are not arrogant. They know the limits of their own wisdom." Stern indeed, that ancient gaze. "Unlike you, Harry."

"Choose between one good and another," Harry echoed flatly. "Like Hermione Granger's life, versus a hundred thousand Galleons." The rage and indignation Harry wanted to put into his voice wasn't quite there, for some reason, maybe because -

"You are hardly in a position to speak to me of that, Harry Potter." The Headmaster's voice was deceptively soft. "Or what was that look of reluctance that I saw upon your face, there in the Most Ancient Hall?"

The sense of inward hollowness grew worse. "I was looking for other alternatives," Harry bit out. "Some way to save her that didn't lose the money."

Wow, said Ravenclaw. You just told an outright lie. Not only that, I think you actually believed it for the seconds it took to say it. That's kinda scary.

"Is that what you were thinking, Harry?" The blue eyes were keen, and there was a terrifying moment when Harry wondered if the world's most powerful wizard could see right past his Occlumency barriers.

"Yes," Harry said, "I flinched away from the pain of losing all the money in my vault. But I did it! That's what counts! And you -" The indignation that had faltered out of Harry's voice returned. "You actually put a price on Hermione Granger's life, and you put it below a hundred thousand Galleons!"

"Oh?" the old wizard said softly. "And what price do you put on her life, then? A million Galleons?"

"Are you familiar with the economic concept of 'replacement value'?" The words were spilling from Harry's lips almost faster than he could consider them. "Hermione's replacement value is infinite! There's nowhere I can go to buy another one!"

Now you're just talking mathematical nonsense, said Slytherin. Ravenclaw, back me up here?

"Is Minerva's life also of infinite worth?" the old wizard said harshly. "Would you sacrifice Minerva to save Hermione?"

"Yes and yes," Harry snapped. "That's part of Professor McGonagall's job and she knows it."

"Then Minerva's value is not infinite," said the old wizard, "for all that she is loved. There can only be one king upon a chessboard, Harry Potter, only one piece that you will sacrifice any other piece to save. And Hermione Granger is not that piece. Make no mistake, Harry Potter, this day you may well have lost your war."

And if the old wizard's words hadn't hit quite so hard, and quite so close to home, Harry might not have said what he said then.

"Lucius was right," Harry ground out. "You never had a wife, you never had a daughter, you've never had anything but war -"

The old wizard's left hand closed hard upon Harry's wrist, bony fingers digging into the still-developing muscle of Harry's arm, and for a moment Harry was paralyzed with the shock of it, he had forgotten what it meant that adults were stronger.

Albus Dumbledore did not seem to notice. He only turned, dragging Harry with him, and moved forward in hard steps toward the wall of the room.

"Phoenix's price."

Harry was pulled up along the black stairs.

"Phoenix's fate."

The room of black pedestals, silver light falling on shattered wands.

"You think," yelled Harry, after his lips unlocked, "that you can win any argument, just by standing here?"

The old wizard ignored him, dragging Harry across the room. His right hand, no longer holding his wand, grabbed up a vial of silver fluid -

Harry blinked in shock; the vial of silver fluid had been standing next to a picture of Dumbledore, or so it had appeared to Harry in the brief moment before he was dragged past.
