Harry Potter and the Methods of Rationality discussion thread, March 2015, chapter 114 + chapter 115

Gondolinian

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 114, and also, as a special case due to the exceptionally close posting times, chapter 115.

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Eliezer Yudkowsky which is not supposed to be publicly available (which includes public statements by Eliezer that have been retracted).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.

I'm sure he realizes it, but Harry literally obliviated everything in his memory, which would presumably include knowledge of any anti-obliviation counter measures (like the signals that were mentioned early on).

Unless there's some spell or artifact we haven't heard of before now that blocks/reverses Obliviation, I am going with it worked. And from a meta perspective, we know the story is winding down, so Voldie coming back with his full memory and then having another showdown with a different solution seems highly unlikely.

LV would anticipate this, so he should have something set up that will explain it all over to him again, automatically. Compare Fiona in Harry Potter and the Natural 20; LV could have done what she did, and she used no magic (and no Muggle technology more advanced than audiocassette recordings).

There is an artifact that might suffice, the Pensieve. Voldemort might have prepared such an artifact with all his memories, and had Bellatrix and/or others ready to restore them to him by it if necessary. But I grant the extreme difficulty Voldemort is likely to have having been transfigured into a ring. If necessary, Harry can always do with the ring what Voldemort did with the Horcruxes and ensure it is lost forever.

I agree with this interpretation. But given that, I'm not sure why Harry thinks he didn't kill Voldemort.
