Harry Potter and the Methods of Rationality discussion thread, part 21, chapters 91 & 92

NancyLebovitz

This is a new thread to discuss Eliezer Yudkowsky’s Harry Potter and the Methods of Rationality and anything related to it. This thread is intended for discussing chapters 91 & 92 . The previous thread has passed 500 comments.

There is now a site dedicated to the story at hpmor.com, which is now the place to go to find the authors notes and all sorts of other goodies. AdeleneDawner has kept an archive of Author’s Notes. (This goes up to the notes for chapter 76, and is now not updating. The authors notes from chapter 77 onwards are on hpmor.com.)

The first 5 discussion threads are on the main page under the harry_potter tag. Threads 6 and on (including this one) are in the discussion section using its separate tag system. Also: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17,18,19,20.

Spoiler Warning: this thread is full of spoilers. With few exceptions, spoilers for MOR and canon are fair game to post, without warning or rot13. More specifically:

You do not need to rot13 anything about HP:MoR or the original Harry Potter series unless you are posting insider information from Eliezer Yudkowsky which is not supposed to be publicly available (which includes public statements by Eliezer that have been retracted).

If there is evidence for X in MOR and/or canon then it’s fine to post about X without rot13, even if you also have heard privately from Eliezer that X is true. But you should not post that “Eliezer said X is true” unless you use rot13.

Does anyone else find it implausible that Quirrell would both act upon the latest prophecy moments after hearing it and act as though he interpreted it in the most literal sense possible? To suppose that he is acting out of concern when speaking to McGonagall is to accept that this is what he does.

Yet, it has been made explicit in HPMoR that prophecies are riddles addressed to the one who hears it. Quirrell knows this. I thus find it unlikely that he would jump on the first ''obvious'' literal interpretation rather than ponder the riddle.

Not to mention that if Quirrell did embrace the line about the world ending in the most explosive, catastrophic and literal sense possible, and that it alarmed him, it would be foolish of him to say nothing of the prophecy. And Quirrell--we know that at least--is not foolish.

So, if the prophecy about the end of the world is a riddle, what could be its answer?

My hypotheses so far:

Harry tries to revive Hermione, and the knowledge he acquires in order to do so (whether or not he succeeds) lets him solve the riddle of what magic is/how it is ruled. He chooses to make that knowledge public, thus changing the face of the magical world to those who live it it. (50% estimate)
Harry will succeed in actually cheating death, and either as a result or through the means he employs to do it, this will affect the source of magic in a way that will change some of its features. (40% estimate)
Harry does not succeed in reviving Hermione, and this somehow ends up in the world catching on fire. (5% estimate).
Harry is not the one whom the prophecy refers to. It could be Snape, for example. (2% estimate).

So, if the prophecy about the end of the world is a riddle, what could be its answer?

The only outcome I've found any hints for so far is the intelligence amplification hypothesis. The last time Harry brainstormed ways to achieve ultimate power, mind magic was first on the list. And he was recently heard to say 'I will change and be less stupid'. IA breaks the plot, though, and leaves the author with a character he can't write, so I'm not hugely confident of it.
