Harry Potter and the Methods of Rationality

"The vitally important technique which I demonstrated," said Professor Quirrell, "was how to lose. You may go, Mr. Goyle, thank you."

Mr. Goyle walked off the platform, looking rather bewildered. Harry felt the same way.

Professor Quirrell walked back to his desk and resumed leaning on it. "Sometimes we forget the most basic things, since it has been too long since we learned them. I realized I had done the same with my own lesson plan. You do not teach students to throw until you have taught them to fall. And I must not teach you to fight if you do not understand how to lose."

Professor Quirrell's face hardened, and Harry thought he saw a hint of pain, a touch of sorrow, in those eyes. "I learned how to lose in a dojo in Asia, which, as any Muggle knows, is where all the good martial artists live. This dojo taught a style which had a reputation among fighting wizards as adapting well to magical dueling. The Master of that dojo - an old man by Muggle standards - was that style's greatest living teacher. He had no idea that magic existed, of course. I applied to study there, and was one of the few students accepted that year, from among many contenders. There might have been a tiny bit of special influence involved."

There was some laughter in the classroom. Harry didn't share it. That hadn't been right at all.

"In any case. During one of my first fights, after I had been beaten in a particularly humiliating fashion, I lost control and attacked my sparring partner -"

Yikes.

"- thankfully with my fists, rather than my magic. The Master, surprisingly, did not expel me on the spot. But he told me that there was a flaw in my temperament. He explained it to me, and I knew that he was right. And then he said that I would learn how to lose."

Professor Quirrell's face was expressionless.

"Upon his strict orders, all of the students of the dojo lined up. One by one, they approached me. I was not to defend myself. I was only to beg for mercy. One by one, they slapped me, or punched me, and pushed me to the ground. Some of them spat on me. They called me awful names in their language. And to each one, I had to say, 'I lose!' and similar such things, such as 'I beg you to stop!' and 'I admit you're better than me!'"

Harry was trying to imagine this and simply failing. There was no way something like that could have happened to the dignified Professor Quirrell.

"I was a prodigy of Battle Magic even then. With wandless magic alone I could have killed everyone in that dojo. I did not do so. I learned to lose. To this day I remember it as one of the most unpleasant hours of my life. And when I left that dojo eight months later - which was not nearly enough time, but was all I could afford to spend - the Master told me that he hoped I understood why that had been necessary. And I told him that it was one of the most valuable lessons I had ever learned. Which was, and is, true."

Professor Quirrell's face turned bitter. "You are wondering where this marvelous dojo is, and whether you can study there. You cannot. For not long afterward, another would-be student came to that hidden place, to that remote mountain. He-Who-Must-Not-Be-Named."

There was the sound of many breaths being drawn in simultaneously. Harry felt sick to his stomach. He knew what was coming.

"The Dark Lord came to that school openly, without disguise, glowing red eyes and all. The students tried to bar his way and he simply Apparated through. There was terror there, but discipline, and the Master came forth. And the Dark Lord demanded - not asked, but demanded - to be taught."

Professor Quirrell's face was very hard. "Perhaps the Master had read too many books telling the lie that a true martial artist could defeat even demons. For whatever reason, the Master refused. The Dark Lord asked why he could not be a student. The Master told him he had no patience, and that was when the Dark Lord ripped his tongue out."

There was a collective gasp.

"You can guess what happened next. The students tried to rush the Dark Lord and fell over, stunned where they stood. And then..."

Professor Quirrell's voice faltered for a moment, then resumed.

"There is an Unforgiveable Curse, the Cruciatus Curse, which produces unbearable pain. If the Cruciatus is extended for longer than a few minutes it produces permanent insanity. One by one, the Dark Lord Crucioed the Master's students into insanity, and then finished them off with the Killing Curse, while the Master was forced to watch. When all his students had died in this way, the Master followed. I learned this from the single surviving student, whom the Dark Lord had left alive to tell the tale, and who had been a friend of mine..."

Professor Quirrell turned away, and when he turned back a moment later, he once again seemed calm and composed.
