Harry Potter and the Methods of Rationality discussion thread, part 17, chapter 86

Alsadius

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 86. The previous thread has long 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.

As a reminder, it’s often useful to start your comment by indicating which chapter you are commenting on.

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Yudkowsky which is not supposed to be publicly available (which includes public statements by Eliezer that have been retracted).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

Voldemort tried to kill Harry

One person's modus ponens is another person's modul tollens. Reading this chapter made me update that Voldemort actually never tried to kill Harry.

He came for Harry (but he never said he came to kill him), probably motivated by the prophecy.
He killed everyone around (but he gave Lily a chance to leave).
He did something that resulted with scar on Harry's head.
Then someone (who exactly, if the event had no survivor besides a baby?) spread a story about how reflected death spell killed Voldemort.
And since then, nobody has ever seen Voldemort again.

From more recent history (Quirrel's description and self-description -- although he could have lied to us/Harry) we can reason that:

Quirrel enjoys company of smart people.
Quirrel enjoys role-playing; but he recently prefers role-playing a good guy, because villains naturally attract insane people.
Quirrel does not hesitate to kill people who cross his path, but that is instrumental, not a terminal value.
Quirrel is very, very smart.

So I guess that Voldemort, after hearing the prophecy, did not panic and try to kill Harry (unlike the Canon!Voldemort). Assuming that Voldemort/Quirrel is extremely smart and he knows how the prophecies work, he could expect that trying to kill Harry -- without "marking him as his equal" first, whatever that means -- would somehow magically fail, and that is an unnecessary risk.

Perhaps the original plan was to simply take Harry and raise him as a Sith apprentice; to make him Voldemort's equal in skill, but also charm him into a smarter version of Bellatrix Black. (Converting is better than killing, because you gain an ally; like Harry later tried with Draco.) But during the action he realized that people expect him to kill Harry, and that this could be a convenient way to get rid of the Voldemort persona. So he just -- made Harry his horcrux? performed on him a brain surgery to raise his IQ? -- and disappeared, pretending to be dead; only to return to Harry later as Quirrel.

I tend to think any line of action which ends up with Riddle losing his body and having to fall back on his horcruxes, given that he apparently wants his old powers back based on his efforts to get at the ingredients to revive himself and/or the Philosopher's Stone, probably contained some element of accident.

Also, the act of training his prophesied enemy, one of whom is bound to vanquish "all but a remnant" of the other, doesn't sound like a great way to serve his own interests. It's not like he's likely to subvert the prophesy and gain a power... (read more)
