Then Harry took off his left shoe, and his left sock, and took off the toe-ring that was Hermione Granger, the Transfigured shape identical to the toe-ring that had been given Harry as an emergency portkey.

(Chapter 111)

"Dumbledore resumed his examination. Harry had to remove his left shoe, and take off the toe-ring that was his emergency portkey if someone kidnapped him and took him outside the wards of Hogwarts (and didn't put up anti-Apparition, anti-portkey, anti-phoenix, and anti-time-looping wards, which Severus had warned Harry that any inner-circle Death Eater would certainly do). It was verified that the magic radiating from the toe-ring was indeed the magic of a portkey, and not the magic of a Transfiguration. The rest of Harry was deemed clear."

(Chapter 94)

Before that meeting Harry fiddled briefly under his sheets. Maybe he took the Transfigured ring off and put the real one on at that time?

Alternatively, he might have used a different hiding-place for Hermione back then and only Transfigured her into the toe-ring later.

How is Voldemort resurrecting Hermione?

With his own resurrection, he's transfiguring stuff into his body, using the Stone to make the transfiguration permanent, then having his spirit repossess the body.

With Hermione, the body was never the problem. Where's he getting the spirit? How does the Stone help?

Where's he getting the spirit?

Harry's Patronus appears to have solved that problem, although we don't know how. "Not another Tom Riddle" suggests that it worked.

How does the Stone help?

Hermione's body needs significant repair, and the only way we know of for the repairs in question (once the person is dead) is permanent Transfiguration.

Either this is still all in the mirror

I think it's more plausible that the mirror acts like it does in canon; that is, you see the room you're in, plus some features that you deeply desire; you don't see yourself leave the room unless you actually leave the room.

Harry needs to buy lottery tickets right away.

I see three broad paths the next chapter could take:

  1. Hermione, wake up! We won and now we have to rescue Dumbledore!
  2. "You thought that would stop me? Now we fight!"
  3. "You thought that would stop me? I had just made a horcrux for her, and your Patronus plus my horcrux is how we're going to solve the death problem. You've failed my loyalty test. And after all I did for you!"

(As always, there is the category of "everything else.")

They did leave the room and go to a graveyard before Hermione was resurrected.

Voldemort would not have given the properties to his body before now, because he had not had the Stone, and without its permanence effect, after a few hours the transferred properties would wear off.

He was overconfident in giving them to Hermione now, instead of to himself.

Voldemort would not have given the properties to his body before now, because he had not had the Stone, and without its permanence effect, after a few hours the transferred properties would wear off.

Voldemort also says that the subject sometimes dies when the properties wear off, so he has very good reason not to give them to his body earlier.

Harry cast a spell on Hermione just minutes prior.

A spell imbuing her with his magic and life force, which would never return to him.

I imagine that's what cause the resonance reaction.

True, but then Voldemort performed magical rituals on Hermione. I imagine that ritual magic would also count as magic interacting, although it's possible that it doesn't.

It's also possible that the Patronus is somehow protective from whatever Dark magic Voldemort just attempted (and needed to kill Quirrell for). Good point, in any case.

Some quick predictions before the next chapter, adding to my previous prediction comment:

Conditional on the Mirror being involved in a test meant to distinguish some subset of rationalists (not necessarily a proper subset) from other people, Harry will pass its test by the end of the story. 95% (See my previous prediction comment for why I think this is a sufficiently plausible hypothesis to condition on.)

Conditional on the Mirror being involved in a test meant to distinguish Light Rationalists from other people, Voldemort will not pass its test without significant change to his values. 95% (See my previous prediction comment for why I think this is a sufficiently plausible hypothesis to condition on.)

So it looks like some of Harry's magic is on the diary for whatever reason, because Voldemort casting a spell on the diary sets off the resonance hard. Did Harry cast a spell on it earlier?

Harry Potter and the Methods of Rationality discussion thread, February 2015, chapter 111

3 b_sen 25 February 2015 06:52PM

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 chapter 111.

There is 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.)

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.

Grab the Elder Wand, Harry!

...

Is Dumbledore also passing the Line of Merlin to Harry? We don't know what's required to pass the Line between holders.

Observe that the writing on the back of the Mirror is in runes, not any particular alphabet. The fact that Harry can read anything out of them at all suggests that there is an effect meant to make them 'readable' regardless of what languages / alphabets the reader knows. This effect was presumably placed by someone who knew what the Mirror does and wanted to make sure that knowledge was preserved even if languages changed and the history of the Mirror was lost.

But then why would someone want to obscure the answer by making those runes the Words of False Comprehension? The end result of having both effects in place is that readers get a simple puzzle in a language they know, hidden behind a magical effect that makes them believe they understand the runes without any further effort. What goal would motivate a great effort to make the puzzle solvable, but only if you realize it’s there to be solved?

My answer is that it’s not a test of "can you read backwards and fix some spacing in a language you know," it’s a test of basic rationality skills. The word reversal and changed spacing is just to prevent bypassing the rationality test.

What would someone reading the back of the Mirror need to do, to solve the puzzle? Ask the fundamental question of rationality: "What do I think I know, and why do I think I know it?" Realize that their initial beliefs about the meaning of the runes are free-floating beliefs, ones that don’t connect to the rest of their beliefs and don’t constrain anticipations. Realize that the free-floating beliefs are useless, discard them, and look past the false feeling of comprehension. Find the real puzzle, possibly aided by hearing that the runes are Words of False Comprehension.

And then once they’ve found it and converted it to words they recognize, put in the effort to understand what the words actually mean and connect those words to the rest of their beliefs rather than guessing the teacher’s password. We know that "coherent extrapolated volition" has a specific technical meaning, but Harry doesn’t and is going to have to work it out from his knowledge of English and stories about the Mirror.

Also: "It is claimed by several authorities that the Mirror alone of all magics possesses a true moral orientation".

So here are my predictions:

At the end of Chapter 109, Quirrell and Harry are trapped in an alternate plane generated by the Mirror. 65%

Harry and Quirrell are going to wind up on different sides of the Mirror. 60%

Confunded!Quirrell received a fake Stone. 50%

Quirrell’s conception of Dumbledore, as Quirrell used to Confund himself, lacks full human wish complexity. 80%

There is a magical 'translation' effect (not the False Comprehension effect, although both may be part of the same spell) on the runes on the Mirror which enables people to 'read' the runes. 95%

The Mirror is involved in a test meant to distinguish some subset of rationalists (not necessarily a proper subset) from other people. 80%

The Mirror is involved in a test meant to distinguish Light Rationalists from other people, under some conception of Light / Good. 75%

Conditional on the Mirror being involved in a test meant to distinguish some subset of rationalists (not necessarily a proper subset) from other people, passing the test grants some type of additional power (including from knowing more about the Mirror and therefore being better able to use it). 90%

My previous prediction comment is here.

Also, the subtle hints at reflective consistency are both funny and hints to Harry about the Mirror's nature.
