Harry Potter and the Methods of Rationality

"That's only if you use your power for evil," explained Harry. "If you use the power for good, you're a Light Lord."

"I see," Professor Quirrell said. He tapped his other cheek with a finger. "I suppose I can work with that. But Mr. Potter, while the scope of your ambition is worthy of Salazar himself, how exactly do you propose to go about it? Is step one to become a great fighting wizard, or Head Unspeakable, or Minister of Magic, or -"

"Step one is to become a scientist."

Professor Quirrell was looking at Harry as if he'd just turned into a cat.

"A scientist," Professor Quirrell said after a while.

Harry nodded.

"A scientist?" repeated Professor Quirrell.

"Yes," Harry said. "I shall achieve my objectives through the power... of Science!"

"A scientist!" said Professor Quirrell. There was genuine indignation on his face, and his voice had grown stronger and sharper. "You could be the best of all my students! The greatest fighting wizard to come out of Hogwarts in five decades! I cannot picture you wasting your days in a white lab coat doing pointless things to rats!"

"Hey!" said Harry. "There's more to science than that! Not that there's anything wrong with experimenting on rats, of course. But science is how you go about understanding and controlling the universe -"

"Fool," said Professor Quirrell, in a voice of quiet, bitter intensity. "You're a fool, Harry Potter." He passed a hand over his face, and when that hand had passed, his face was calmer. "Or more likely you have not yet found your true ambition. May I strongly recommend that you try to become a Dark Lord instead? I will do anything I can to help as a matter of public service."

"You don't like science," Harry said slowly. "Why not?"

"Those fool Muggles will kill us all someday!" Professor Quirrell's voice had grown louder. "They will end it! End all of it!"

Harry was feeling a bit lost here. "What are we talking about here, nuclear weapons?"

"Yes, nuclear weapons!" Professor Quirrell was almost shouting now. "Even He-Who-Must-Not-Be-Named never used those, perhaps because he didn't want to rule over a heap of ash! They never should have been made! And it will only get worse with time!" Professor Quirrell was standing up straight instead of leaning on his desk. "There are gates you do not open, there are seals you do not breach! The fools who can't resist meddling are killed by the lesser perils early on, and the survivors all know that there are secrets you do not share with anyone who lacks the intelligence and the discipline to discover them for themselves! Every powerful wizard knows that! Even the most terrible Dark Wizards know that! And those idiot Muggles can't seem to figure it out! The eager little fools who discovered the secret of nuclear weapons didn't keep it to themselves, they told their fool politicians and now we must live under the constant threat of annihilation!"

This was a rather different way of looking at things than Harry had grown up with. It had never occurred to him that nuclear physicists should have formed a conspiracy of silence to keep the secret of nuclear weapons from anyone not smart enough to be a nuclear physicist. The thought was intriguing, if nothing else. Would they have had secret passwords? Would they have had masks?

(Actually, for all Harry knew, there were all sorts of incredibly destructive secrets which physicists kept to themselves, and the secret of nuclear weapons was the only one that had escaped into the wild. The world would look the same to him either way.)

"I'll have to think about that," Harry said to Professor Quirrell. "It's a new idea to me. And one of the hidden secrets of science, passed down from a few rare teachers to their grad students, is how to avoid flushing new ideas down the toilet the instant you hear one you don't like."

Professor Quirrell blinked again.

"Is there any sort of science you do approve of?" said Harry. "Medicine, maybe?"

"Space travel," said Professor Quirrell. "But the Muggles seem to be dragging their feet on the one project which might have let wizardkind escape this planet before they blow it up."

Harry nodded. "I'm a big fan of the space program too. At least we have that much in common."

Professor Quirrell looked at Harry. Something flickered in the professor's eyes. "I will have your word, your promise and your oath never to speak of what follows."

"You have it," Harry said immediately.

"See to it that you keep your oath or you will not like the results," said Professor Quirrell. "I will now cast a rare and powerful spell, not on you, but on the classroom around us. Stand still, so that you do not touch the boundaries of the spell once it has been cast. You must not interact with the magic which I am maintaining. Look only. Otherwise I will end the spell." Professor Quirrell paused. "And try not to fall over."

Harry nodded, puzzled and anticipatory.
