Update: Discussion has moved on to a new thread.
The load more comments links are getting annoying (at least if you're not logged in), so it's time for a new Harry Potter and the Methods of Rationality discussion thread. We're also approaching the traditional 500-comment mark, but I think that hidden comments provide more appropriate joints to carve these threads at. So as of chapter 67, this is the place to share your thoughts about Eliezer Yudkowsky's Harry Potter fanfic.
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: one, two, three, four, five, six. The fanfiction.net author page is the central author-controlled HPMOR clearinghouse with links to the RSS feed, pdf version, TV Tropes pages, fan art, and more, and AdeleneDawner has kept an archive of Author's Notes.
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Eliezer Yudkowsky which is not supposed to be publicly available (which includes public statements by Eliezer that have been retracted).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.
He's quite prepared in a Hero's Journey sense, though. In Harry's own mind, he has lost his mentor. Thus, he is now free to be a mentor. And what better way to grow, as a Hero and über-rationalist, than to teach others to do what you do?
Of course, Harry would say that he's already doing that with Draco—but in the same way that he usually holds back his near-mode instrumental-rationalist dark side, he's holding back the kind of insights that Draco would need to think the way Harry thinks; Harry is training Draco to be a scientist, but not an instrumental rationalist, and therefore, in the context of the story, not a Hero. (To put it another way: Draco will never one-box. He's a virtue-ethicist who is more concerned with "rationality" as just another virtue than with winning per se.)
Mentoring Hermione would be an entirely different matter: he would basically have to instill a dark side into her. Quirrel taught Harry how to lose—Harry would have to teach Hermione how to win.
If Eliezer has planned MoR as a five-act heroic fantasy, it will probably go like this; usually, in a five-act form, acts 4 and 5 mirror the character developments of the Hero in 2 and 3 in another character, for the purposes of re-examining the (developed, and now mostly stagnant) Hero's growth and revealing by juxtaposition what using that particular character as Hero brought to the journey.
It seems more likely to be a three-act form at this point, though, with Azkaban as the central, act 2 ordeal. That's not to say the story is more than half-over already, though; Harry has just found his motivation for acting instead of reacting (to change the magical world such that Azkaban is no longer a part of it.)
Hermione knows how to win. She won the first mock battle quite resoundingly. She doesn't necessarily know how to hurt people for the greater good though.
