Harry Potter and the Methods of Rationality discussion thread, part 25, chapter 96

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 chapter 96. The previous thread is at almost 300 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, 21, 22, 23, 24, .

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Yudkowsky which is not supposed to be publicly available (which includes public statements by Eliezer that have been retracted).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

Or it's the ritual to create dementors. Quirrel says that "the spell to dismiss Death is lost" and nobody knows how to destroy a dementor.

I like this line of reasoning. I've been batting around the idea that Dementors and Patronuses are essentially opposite (anti) versions of one another. Perhaps a dementor is made when someone tries to cast the Patronus Charm with entirely 'the wrong kind of thought to cast a Patronus Charm.'

A dark ritual would explain their persistence compared to the patronuses, but it doesn't adequately explain their number... Also, if the ritual created a dementor, wouldn't people be saying the ritual summons a dementor, rather than Death? Most people in hpmor se... (read more)
