(The HPMOR discussion thread after this one is here.)

The previous thread is over the 500-comment threshold, so let's start a new Harry Potter and the Methods of Rationality discussion thread.  This is the place to discuss Eliezer Yudkowsky's Harry Potter fanfic and anything related to it. The latest chapter as of 09/09/2011 is Ch. 77.


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, seven, eight.  The fanfiction.net author page is the central location for information about updates and links to HPMOR-related goodies, 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Eliezer Yudkowsky which is not supposed to be publicly available (which includes public statements by Eliezer that have been retracted).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.

Has it occurred to anyone else how good magic would be for psychological experimentation?

To start with, imagine you get the consent of your subjects to be Obliviated. Then, you can try exposing the subjects to differing stimuli while they're in exactly the same starting state, and you can precisely and easily measure the effect of whatever change you've made.

Even better, imagine the marketing opportunities. Think of Mr Hat and Cloak's dictionary attack, but with a focus group, and different advertisements for your new product. Show them the ad, then ask them how much they liked it, then Obliviate them again.

Also, you could try to remove the effect of priming on yourself with self-targeted obliviation.

And you could go on 4chan, knowing that what has been seen actually can be unseen, leaving you with only a note saying "Don't look at SqueeHorse" or something.

I really want magic.

I wonder if there's a different attitude toward spoilers or "great works of art" in the Wizarding World because of memory charms. Hats which could charm endings or plots out of people's minds, people who would only read one book over and over again by repeatedly blasting it out of their heads, or museums/theme parks Obliviating any previous experience there so that every time is fresh.

Would also like to see Eliezer lampshade the Snape kills Dumbledore spoiler by having everyone present self obliviate or something similar.

Meh. I did just google lemon party, and the impact was just about zero. That's supposed to be a shock image? Goatse had some impact on me when I first saw it years ago, as did 2g1c, but the mere memory of either of those doesn't (how could a memory shock?). I can't even imagine wanting to erase the memories, what for? I might want to store pleasant memories in a pensive to experience something pleasant "for the first time" a second time in different way, and then restore the original memory, but looking at goatse for the first time is not exactly something I consider pleasant (though not as big a deal as some seem to either).

I dunno. Personally I haven't been able to look at chocolate milkshakes the same way for a while, and I used to actually like them, so that's a memory I would prefer buried. (But goatse was just mildly impressive, and lemonparty didn't even merit a twinge.) Probably everyone reacts differently to that sort of thing.

This is heading straight into mindkiller territory, but there's a style of reading which involves tracking everything that might be offensive in a story. The thing is, sometimes what looks like reasonable deductions of background beliefs is a result, but it's a hell of a way to treat fiction as a matter of habit.

Offensive to whom? If you personally aren't really offended by anything, are you immune to this?

In three worlds collide there's the non-consensual sex plot point that some people misunderstood as being misogynist rather than the result of EY selecting a particularly unusual point in culturespace. Is this the kind of analysis you are talking about?

I really just don't see how this meme could infect you unless you already have a disposition of looking for things to take offense to.

The point as I understand it was to have the humans not have exactly our moral system. Morals evolve over time, and most people in any given generation would be shocked by the ethical and moral attitudes of people a few generations down the line. This attitude of the population reflects that. It also helps broaden the scope of the questions raised by not making one of the moral systems identical to our general moral system, so we don't immediately look at the morality of the humans and just say "but that's the right system!"

Overall, while I think I understand why Eliezer did this, it seems to be a very tiny benefit for a very large distraction. Overall, a net negative in getting his points across.

I have an idea for an epic maneuver that a wizard could perform as a last resort in certain emergency situations. A severely wounded wizard could, if there is something of much greater utility then his own life on the line, transfigure himself into a healthy version of himself in order to continue the fight. This would be a death sentence, but still worth it if the stakes were high enough.

Then again Harry can already sustain a small transfigured object even in his sleep. Perhaps the most powerful of wizards could sustain a transfiguration on their own body indefinitely. Or... Professor McGonagall said that it would be possible for a child to transfigure themselves into an adult bodily form. Perhaps if the wizard could not sustain an object the size of their own body indefinitely after the emergency situation has passed they could again transfigure themselves into a adolescent, child, or midget form in order to achieve a body with a volume that they could sustain. Unless doing another transfiguration would cause the consequences of the previous transfiguration to be imposed on the new form. Though I don't see why that would necessarily be the case.

This would be a very fragile sort of existence. They would be much weaker due to the constant drain on their magic and incapacitation or anything that dispels the transfiguration would result in death.

...Is it just me, or should that create a post-scarcity economy? Because that lets you make food in ways that violate the conservation of energy.

How to survive as a wizard:

  1. Get some nutritious, nonperishable food.
  2. Make more.
  3. Eat, but not all of it.
  4. Repeat steps 2-3 indefinitely.

Water isn't a problem, since aguamenti conjures it.

So, question: why are there house elves? Why does Mrs. Weasley cook?

...Why can't the Weasleys buy a can of Coca-Cola, create as many more as they want and sell them? And do the same with hot dogs? And get rich?

The dark secret, AspiringKnitter, is that all the food magic actually works on the same principle as the Hogwarts Hall meals - enslaved house-elves in obscure kitchens.

American liberal, which I think means socialist in the rest of the world

Just a minor nitpick, I think it's the other way around. I'm reasonably sure that the American form of liberalism is usually on the right end of the political spectrum in other Western democracies. What is called liberal in other countries is what many Americans would call socialist and what is called moderate is 'American liberal'. Specifically, the Democratic Party's (the major party that most Americans call liberal) significant policy stances would probably be considered moderate in Great Britain and conservative in Denmark.

Nope, in France "libéral" is closer to American "libertarian", i.e. pro-free markets, anti-welfare (as opposed to the "mainstream" right wing, which isn't particularly hostile to big government, and is more about traditional values and whatnot, and of course as opposed to the socialists and other left-wingers, who are very much at odds with the liberals). I think "liberal" has the same meaning in most of Europe (and in most of the world, though I'm less sure of that), and Americans and Canadians are more of the exception (where for historicaly reasons "socialist" had anti-American connotations, so the label "liberal" was adopted instead. This is a gross oversimplification).

Thank you for the clarification. I did remember that in other countries liberal meant classically liberal as opposed to American modern liberalism. So in France, "libéral" is economically liberal but not necessarily socially permissive? Or did you mean "small-l libertarianism" when you referred to American "libertarian" and not the Libertarian Party?

Let me rephrase: we would consider your socialists liberal, even though certain parts of the world have a political spectrum shifted so far to the left that even your right-wing parties are liberal. In this case I meant that I wonder whether Magical Britain is as far to the left as regular Britain.

Ha, I had another thought that this could explain professor Flitwick's size, but that is probably something that you would want to be common knowledge. You wouldn't want someone accidentally casting Finite on you. Then again I think it has been said that the effectiveness of Finite is depended on the power of the caster, so Flitwick being a former dueling champion may not need to fear it being accidentally dispelled.

Ok. I really don't like the new omake with the ponies.

I understand that Eliezer is trying to criticize overemphasis on peer review. But the bottom line is that peer review is really important: groups of humans who look at something critically are much more likely to notice mistakes and flaws then one will notice by one's self. This is not a trivial point.

Indeed, when I sat down to make a rationalist MLP fanfic, I realized that the only part of the show that I would change is possibly Feeling Pinkie Keen.

Yea. The approach to making an MLP rationalist fanfiction is not to change the original material, it's by working within the set format to provide rationalist lessons. If done properly probably indistinguishable from the canon episode scripts except for not being in a scrip format and being about slightly more advanced subject matter.

For example, from what I've herd about the minicamp:

"Dear princess Celestia, today I learned that although the idea that someponies opinion of you is infuenced by somehting as arbitary and wastefull as fashion might seem unpalatable, it can non the the less be unwise to ignore the fact that it is, even amoung friends. Ponies can not always control their subconius impresions, and this is no reason to in turn judle them.

  • Your faithful student, Twilight Sparkle."

I think you're both thinking a bit too narrowly about the topic of rationalist MLP fanfiction. It needn't be about correcting irrationalities of the original material (which I'm guessing was Vaniver's approach?) but it doesn't need to just follow the show's "how to treat your friends" moral lessons either... It could introduce new readers to some really advanced LessWrong concepts.

...ooph, I don't know if I should share the ideas I have on this or not. Because I am thinking of writing rationalist MLP fanfiction, and if so I'd prefer there'd be some surprised delight from readers.... but if I don't end up having the time to write said fanfiction, it's better that I share them, lest they not be known at all.

...I suppose if I don't find the time in the next few months to write said fanfiction fully, I'll just share all the ideas I have on the topic in some thread here and encourage anyone else who wants them to pick them up and use them.

My post wasn't supposed to be "how all rationalist fanfiction should be made", but rather "how I recommend Vaniver to go about it, given the evidence I have about his strengths and weaknesses as a writer". Guess I could have worded it better.

I look greatly forward to reading your fic! In fact, since given the priors I have over LWers I guess I probably know more about MLP lore and fan conventions (remember all those things Eliezer said in MoR authors notes about the importance of fan conventions? You'd BETTER give Luna an abacus! ), I humbly offer myself up as a prereader even thou I probably suck at most editorial work given my zero experience.

Also, once you're done, you REALLY should send it over to Equestria daily. Correcting for writing quality bronies might be an even better recruitment pool than the Harry Potter fandom, since even thou it's smaller it's closer to the LW demographic and I don't think HP has a centralized hub like Equestria Daily which means greater penetration can be reached by something good enough to get on there. In fact, it may be worth having more seasoned LWers, or even Eliezer himself really, look over it for quality.

Personally I've found a lot of the show's lessons to be overly one-sided and applause-lightish. Also, I like/dislike how the show dances around carnivory; I'd love to see HJPEV-Twilight (or whoever) react to Fluttershy explaining how she runs her meadow.

There's also the world mechanics of raising the sun and why only the princesses are immortal and all that, and various smaller mysteries, but (1) lots of fic writers and theorists are probably exploring that, and (2) a lot of it is high-profile enough in the series that it stands a reasonable chance of being elaborated on there. The fact that the Potter books have concluded is one of the advantages to setting a rationalist/munchkin fic there.

Personally I've found a lot of the show's lessons to be overly one-sided and applause-lightish.

Of course. The issues with rewriting them to be rationalist are twofold: first, they're primarily about friendship, where rationality is mostly silent on direct advice, and second, they're on features where one-sided advice is generally better than two-sided advice.

Consider, for example, Twilight's nerdy scholarship. It's shown to be useful (it's a major source of her magical power and she'll often know things because of it) but have its limits (let's learn how to do a slumber party from a book!). Which, of course, is the sort of thing you'll find in any of lukeprog's articles on relationships here. Rationality's primary lesson is "learn from successful examples and build up experience" rather than "book smarts are sufficient to interact with other people in real-time."

As an example of one-sided advice, take the lesson of Bridle Gossip:

Never judge a book by its cover. Someone may look unusual, or funny, or scary. But you have to look past that and learn who they are inside. Real friends don't care what your "cover" is; It's the contents of a pony that count. And a good friend, like a good book, is something that will last forever.

Obviously, appearances can provide useful information. The standard human bias, though, is to overweight appearance- and so advice to humans should generally be along the lines of "discount appearance" rather than "use appearance optimally," because the first is harder for humans to twist than the second.

The fact that the Potter books have concluded is one of the advantages to setting a rationalist/munchkin fic there.

I personally dislike the "rationalist fic = munchkin fic" association, but suspect that is atypical of LW users.

The lessons are supposed to be simple - it's a show for little girls after all - and any real wisdom to be found in the show lies elsewhere, mainly on a more meta level in the community rather than canon content, and even then isn't very Deep.

There are many fan theories about carnivory, but most likely the show dancing around it is a consequence of pony society doing so. Given that she's quite the scholar she almost certainly already knows about it, although a city pony with no biology education or experience with animals might not. I don't think anypony would consider it all that big a deal thou or carnivores wouldn't be around or at least not common.

"Applause lights" doesn't mean "simple" or even "wrong"; it's more like "things that sounds good regardless of rightness or wrongness in a particular context". Or at least that's how it makes sense to me to use it.

Surely causal arrows point from creative decisions to show content, not the other way around. More to the point, not all ponies can dance around it; "animals (don't) take care of themselves", so if Fluttershy doesn't feed the snakes they don't eat. And she makes a regular census of at least the bunnies, meaning she might know exactly how many die when Rarity lets Opalescence out.

Given that she's quite the scholar she almost certainly already knows about it, although a city pony with no biology education or experience with animals might not.

I can think of plots that might mitigate that, but yeah, the built-in outsider perspective is another advantage of HP.

I don't think anypony would consider it all that big a deal thou or carnivores wouldn't be around or at least not common.

They might see it as a lesser evil than "wiping out" whole species, or they might have the eventual goal of creating a self-sustaining ecosystem where predators would be necessary. But I think all three of those have potential. Unfortunately there's probably not much interest in writing what would come off as a vegan author tract, even with the difference that the animals would be be sapient.

This surprised me. The definition I'd have given for applause lights would have been "A statement so obviously the Right Thing that it provides no useful information".

So I went back and checked the original article, and it turns out no definition was ever given, just a few examples, and those are compatible with both views and don't fit either perfectly. So I checked your karma in case it was just a noobish mistake by me, precommited to change my mind if you had a lot more than me, but it turns out you have even less. Thus I'd say you were wrong in correcting me.

Also, the answer to your question is there anyway.


By dancing around it I meant the same way humans do with sex or the conditions in factory farms.

From Applause Lights: "I think it means that you have said the word "democracy", so the audience is supposed to cheer. It's not so much a propositional statement, as the equivalent of the "Applause" light that tells a studio audience when to clap."

I think that depending on what you mean by "The Right Thing" (whether you mean it mockingly or actually), you're right or wrong in your understanding of what applause lights means. But either way: the point of "applause lights" is that it's more of a signal for mutual self-congratulation than something with actual meaning/content.

e.g. "God bless the United States of America".

So I checked your karma in case it was just a noobish mistake by me, precommited to change my mind if you had a lot more than me, but it turns out you have even less. Thus I'd say you were wrong in correcting me.

I'm not sure if I'd go so far as to call it mocking, but I certainly meant it in a way not very correlated with actually being correct or moral.


I use total karma as evidence about how likely someone is to be correct about LW conventions, since in order to get very high karma you have to have been here for a long time and have written a lot and thus getting misunderstandings sorted out by being corrected. I also use it as weaker evidence at being correct in general about anything, since I believe LW consensus to be correlated with that. I put LW karma in roughly the same class of evidence as market prices, something which can sometimes say quite silly things but on other occasions be more trustworthy than your own brain. I could actually feel through introspection I weren't able to consider the issue without bias so I just let that decide.

I suspect that he meant something like "Applause Lights" is an LW specific term. Therefore, to a very rough approximation, karma levels may be a rough way of estimating who understands how the term is used around here since karma roughly approximates how much time someone has spent here.

That seems like an extremely weak argument, and I agree that the way it was phrased sounded pretty bad. I don't think my interpretation is that much better.

Then allow me to step in as one of the foremost experts on the writings of Eliezer (self-proclaimed).

All that applause lights 'mean' is "you should clap now". From the wiki:

It's not so much a propositional statement, as the equivalent of the "Applause" light that tells a studio audience when to clap.

(Beware - this example is mind-killing)

Thus, you say "democracy" to get people to nod their head and agree with you. This is not because "democracy" means anything obviously right; also, the label gets applied inconsistently in both directions. The entire purpose of calling something "democracy" in those contexts is to mark it as "approved".

I was correcting your interpretation of my use of the phrase, not your use of it. (On further thought I could reword it "words whose practical meaning is 'applaud this statement'"; that might cover both.)

That doesn't sound like something ponies would do.

Not sure which you mean, but I know there's contradictory evidence to what I cited. I don't think I want to talk about the "reality" of the show, though, just possible fanfic interpretations. My belief about the show is that it'll continue to dance around the subject, and that the occasional slips will continue to contradict each other.

I find discussing "possible" interpretations to be rather pointless because basically anything is possible. There are usually 3 interpretations worth going into any depth of; the one intended by the original author, the one that has become fanon and most fans are in consensus about, and the one that would be most likely if the cannon material was interpreted as true observations about the universe.

It's been awhile since the last update, so here's a scene from the HPMOR in my head.

Hermione offers Harry a Bertie Bott's Every Flavour Bean, warning him that when they say "every flavour" they mean every flavour. The first one that Harry eats is booger-flavoured, and he gets frustrated about the foolish candy-makers, complaining that of all the flavours that he could've gotten, his first bean tasted like boogers. Hermione reminds him that it says "every flavour", so he shouldn't be surprised if it ended up tasting like something nasty. Harry has Hermione list flavours of Bertie Bott's beans that she has eaten, and then goes on a rant:

Out of all possible flavours, every single flavour that Hermione has mentioned is recognizable as something regularly found on or in the human body, and the majority are types of food. Harry tries to explain the concept of flavourspace - the entire set of all possible flavours - and what a skewed understanding of flavourspace wizards must have if "every flavour" beans only draw from the tiny proportion of flavourspace which they already regularly taste. So, yes, he should be surprised that the first bean he ate, which could have taken on any flavour in the vast universe of flavourspace, tasted like something that normally grows just inches from one's taste buds.

I would guess Flamel knows. He's the inventor, and considering that he's stated with confidence that Voldemort couldn't make one himself, and would need to go after the preexisting one, then there must be some really exceptional barriers to anyone else making them. Otherwise Voldemort could simply have imperiused or tortured anyone who could make one in order to get one for himself.

If there were any feasible way to gain control of a philosopher's stone without having to get one's hands on the Philosopher's Stone, it would completely break the story.

Yes, but... just for the sake of argument...

Flamel is an inventor. And when assigning confidence in statements he makes about Philosopher's Stones, you need to bear in mind that he's the only inventor dumb enough to get caught. Anyone who independently invented it before him (or after) managed to keep it secret, that's all.

Or maybe there's more than one way to create a Philosopher's Stone and Flamel discovered the most difficult, so now he has an inflated idea of how hard it would be for someone else to duplicate his feat.

Or possibly Flamel is the Dread Pirate Roberts and there's no such thing as a Philosopher's Stone at all.

The Philosopher's Stone would be phenomenally useful to Quirrelmort, and if it weren't really hard to get, he would presumably already have one. After all, if there's anyone with an incentive to find the easiest way to get their hands on one, it's him.

As for the Philosopher's Stone not being real, I doubt Dumbledore would have gone to such lengths to guard it if he weren't convinced it was, and I doubt tricking him into buying into a fake would be easy.

As to the second: the whole point of having it at Hogwarts to begin with was as bait for a trap, right? If everyone believes it's real, it serves just as well for that purpose as if it actually were real.

Well, if HPMoR is consistent with canon, it would circumvent the need for him to conduct the ritual to get his old body back at all. Dumbledore also suggested it as an alternative route that Voldemort could take to return to power.

And the point of having it at Hogwarts wasn't just as bait for a trap; Voldemort and his minions, even in the original canon, were capable of stealing from even the more secure vaults at Gringotts. In HPMoR, it could just be a trap, but if it's so obvious as to not serve that purpose, and there's nothing to protect, then what's the point?

(Just to save everyone some time, here are the relevant quotes.)

HPMoR Chapter 61, Dumbledore to McGonagall and Snape:

His strongest road to life is the Philosopher's Stone, which Flamel assures me that not even Voldemort could create on his own; by that road he would rise greater and more terrible than ever before. I would not have thought Voldemort able to resist the temptation of the Stone, still less because such an obvious trap is a challenge to his wit. But his second avenue is nearly as strong: The flesh of his servant, willingly given; the blood of his foe, forcibly taken; and the bone of his ancestor, unknowingly bequeathed. Voldemort [...] would certainly seek the most powerful combination: the flesh of Bellatrix Black, the blood of Harry Potter, and the bone of his father. Voldemort's final avenue is to seduce a victim and drain the life from them over a long period; in which case Voldemort would be weak compared to his former power.

Dumbledore, at least, thinks the obviousness of the trap won't preclude its success.

HPMoR Chapter 76, Quirrell to Snape:

A single glance would tell any competent wizard that the Headmaster has laced that corridor with a ridiculous quantity of wards and webs, triggers and tripsigns. And more: there are Charms laid there of ancient power, magical constructs of which I have heard not even rumors, techniques that must have been disgorged from the hoarded lore of Flamel himself. Even He-Who-Must-Not-Be-Named would have had trouble passing those without notice.

That second bit is particularly interesting. It seems to suggest that Flamel would have been capable of protecting the Stone himself just as well as it's being protected now, in which case why have it at Gringotts in the first place?

The question in my mind is: how could Voldemort know if the Stone in Hogwarts is fake or not? I mean, the situation seems to be that Dumbledore went to visit his old teacher Nicholas and came back with a "Philosopher's Stone" in a small leather bag, which he deposited at Gringotts, and later took to Hogwarts. If you assume he actually is trying to protect the Stone, it would pretty much have to be a fake, wouldn't it? (It'd be pretty funny if the real one was teleported into the Marianas Trench or something.)

And I think it's something of a mistake to assume the only reason for breaking Bellatrix out of Azkaban is the resurrection ritual. Suppose that he does already have the Stone - maybe he replaced it with a fake months ago, maybe he invented it on his own, whatever - wouldn't it still be useful to him to retrieve his most powerful and loyal servant?

Bellatrix isn't remotely his most powerful servant anymore after her stay in Azkaban, and he could probably do to someone else what he did to her in the first place. Plus, in canon, once he returned to his former power, he was able to break everyone out of Azkaban. It might not be a great idea to sacrifice the element of surprise by doing so, but still, if he already had a route to power even greater than he possessed before, I don't see why he'd stall on using it.

I would be rather surprised if, after all the characterization and buildup we've been given so far, MoR!Voldemort turned out to be capable of this as well.

As a suggestion: he may have decided that his goals are better served by remaining in his current guise (which he presumably could not do if he regained his body) than by sheer magical power, at least for now.

Personally I'm assuming that Quirrelmort rescued Bellatrix to influence Harry. He now has first-hand evidence that Harry was engaged in a major crime, has shown Harry a part of the Wizarding world which he could never accept which was enabled by democracy, has shown Harry that Dumbledore isn't as proactive as Harry would want him to be, almost convinced Harry that a revolution is necessary, convinced Harry to lie to protect him, and has made Harry feel sorry for Bellatrix. Generating a 'false alarm' of Voldemort's return is a nice side effect as well if he doesn't plan on acting immediately, Dumbledore may well have just expended significant political capital too early. If he was planning on going through with the ritual, then he had Harry right there with him. (Although he could have just taken some blood while Harry was asleep, of course.)

The only motivation I can see for him to retrieve her otherwise is that he couldn't remember what happened at Godric's Hollow or to the Longbottoms, so he wanted to retrieve Bellatrix to find out, he regretted what he did to her (seems unlikely), or he's not Quirrelmort, and is really just a powerful but neutral wizard who wants to try and retrieve some of Slytherin's magics.

The most obvious motivation given what we know about Quirrelmort and what he needs to regain his old power is that he retrieved her for use in the spell that will restore his body. For his motive to be anything else would constitute a twist.

The fic often takes 'joke' aspects of magic and explores their less harmless uses. It leads the reader to be unwilling to take any reference as simply a joke - this as opposed to the original text, where the fact that it was meant to be a children's book led to a lot of bite-sized humorous references with enormous, unexplored potential.

Real World Effects of SPHEW

Raemon has written at moderate length about feminist issues in HPMoR. In fact, this post is credited by Eliezer as

High probability this comment had something to do with the surprise creation of SPHEW.

I don't wish to speculate about these issues because I don't feel I have the depth of knowledge needed to contribute meaningfully. However I do have a real life effect of SPHEW to report.

I produce the Methods of Rationality Podcast. For the most part it's a solo project, but after receiving a few requests I've gotten comfortable enough with it that I've decided to integrate other voices as long as it doesn't require much additional work from me. Meaning - just send me the audio file of you reading the lines and I'll incorporate it if I can. I didn't really expect much response from this approach, and for the most part I didn't get one. Seems no one is really interested in doing Gregory Goyle's lines. :)

With a notable exception. The girls of SPHEW. I received a complete reading of all of Daphne's lines before I even announced I was willing to take other voices. It was one of the primary motivators for overturning my previous policy and saying I would accept others. Since then I also received all Tracey's and the start of Susan's with a commitment of a full reading. I'm still at least two months away from the first appearance of any of the SPHEW witches, and probably a full year away from their eventual official SPHEW adventures.

I believe SPHEW has indeed promoted heroism among witches in the real world. Regardless of what feminist themes may have been explored, it's my opinion that SPHEW has had a positive real-world effect. :)

While I was reading Harry Potter, I kept thinking that the House system was destructive, both in terms of making people impose restrictions on themselves, and creating deep divisions in the wizarding world. Hogwarts is in this sense the primary cause of both the previous and the coming wizard war.

In Eliezer's fiction, it's more apparent that the Hogwarts house system is a mindless, destructive mechanism set in motion hundreds of years ago that no one person can change or escape. Even Dumbledore couldn't abolish the house system; the political pressure would pop him out of Hogwarts like a cork from a champagne bottle.

I don't understand why Dumbledore can't maintain order among the students and protect them from each other, though... it seems to be within the powers of the Hogwarts faculty, if they set their minds to it.

Dumbledore and McGonagall's weaknesses are more apparent in Eliezer's fiction. Which would score realism points with me, except that the deconstruction of the perfect Dumbledore is balanced by the imagination of a perfect Harry.

In my ~10 years at the university, I don't recall ever meeting anyone who joked about hating St John's. And for most of that time I was at Trinity, where you might think John's-hatred (jocular or otherwise) would be strongest.

Until rather recently, Homerton didn't take students in any subject other than Education. Whether that actually meant its students were less intelligent than those of other colleges, I don't know, but it's not an entirely crazy idea. (I think Homerton's subject balance is still quite different from those of the other colleges.)

[EDITED to add: For the avoidance of doubt, I don't mean that people reading education are particularly unintelligent-by-Cambridge-standards. Only that (1) intelligence surely does vary somewhat by subject, and (2) some subjects have the reputation of requiring particularly high intelligence and education isn't one of them. So if there's a stereotype of Homerton students being less intelligent, it probably has causes less crazy, though not necessarily more correct, than mere historical rivalries.]

For another, most of his really impressive feats of intellect and willpower are actually owed to Voldemort's horcrux (his "dark side"), which means Harry doesn't get full credit for them. I think MoR Harry is far from perfect.

You're totally right about the house system, though. That's why I really love the subplot about Quirrel's armies; it breaks up the house system and lets all the students interact more. I'm so glad we got to know the Slytherin girls...

J. K. Rowling was never too bothered with the numbers (by her own admission). In particular the total number of students in Hogwarts is portrayed as much greater than the number of students per year multiplied by seven, and the wizarding world is absurdly small but still far too large to account for the fact that there appears to be only one school in Britain.

The sadder thing is that Eliezer doesn't seem particularly bothered with numbers either. The "armies" each of the generals have are mentioned to have 24 soldiers each.

24x3=72 students in the first year. This would only make sense if the size of the classes in MoR were about twice as big as in canon. But MoR has never mentioned a single non-canonical first-year student, as far as I can remember, which would imply the opposite, that the sizes of the classes must be about as big as in canon (namely about 40 students in the first year, all houses combined).

Most of the teachers? Binns and Trelawney certainly, Snape, but arguably he's more unprofessional and unpleasant than incompetent. Often the defense professor is incompetent, I suppose. Canon!Harry had Lupin, Snape and fake Moody for competent defense professors and Quirrel, Lockhart and Umbridge for incompetent ones. We have no reason to doubt the teaching ability of Mcgonagall, Flitwick, Sprout, Sinistra, Vector or Babbling. Burbage's Muggle studies course is often a subject of ridicule in fanfiction, but that might be a result of the (inter?)-national curriculum rather than her individual competence, and so would be no better at other schools. Hagrid's Care of Magical Creature's lessons were of very uneven quality, but he could teach well when he had his head together.

As to the preeminence of Hogwarts, perhaps its as simple as Hogwarts being the only British school with a comprehensive curriculum, the others focusing on particular areas of magic and functioning more or less as magical trade schools. We don't technically know that there's no entrance exam for the common witch or wizard, we just know Harry didn't have to take one, he could have been admitted as a legacy student or simply because he's the boy-who-lived. Or the barrier could be financial.

In the previous thread there was some discussion on Ch 76's obliviation powered dictionary attack on Hermione. Most of that discussion seems to have assumed that what we saw between Hat And Cloak (HAC) and Hermione was simple to understand and relatively unskilllful... with Hermione's "tootsie pop" response being inane and HAC's probing appearing ham-handedly ignorant.

My impression was that we didn't see the first or second cycle of relatively normal behavior for either character, but more like the 7th cycle (12 minutes per cycle for 90 minutes?), where HAC was doing something radically different each time to probe Hermione's knowledge, feelings, etc in different ways, probably using legilimency. She was exhausted, like someone "in the box" with the police, except more stressful due to not even knowing she's in the box. And the questions don't have to be subtle, they just have to make her think of useful things while her eyes are visible. I don't think she was the ultimate target either, but rather she is the closest non-occlumens to Harry other than possibly Draco, so mind raping her to learn about Harry is "safer" even if it demonstrates horrifying levels of evilness... which raises issues about how to hide that it happened from Albus and Minerva.

I'm curious what other people's takes on the situation are. Specifically, what cycle do you think we saw out of how many total? Also, what are the odds that Hermione will be dead or missing in the next substantive chapter?

I'm not sure how it worked in canon (and would expect semi-random behavior given Rowling's tendency to fudge world building details that a more mechanistic thinker might nail down) but in MoR it appears that legilimency allows the reader to perceive the "conscious surface thoughts" of the readee, plus the feeling of active reading (used by an occlumens to race ahead and put fake conscious surface thoughts in the way), plus the traces of past reading.

When Albus read Harry early in the story to look for traces he asked Harry what Harry had recently eaten so as to prevent himself from reading anything private in Harry's mind. If words can be used to redirect attention to banal issues so that it is impossible for even Albus to see more deeply, it stands to reason (to me anyway) that visibility is relatively shallow and that words could also be used to redirect attention towards the sensitive issues. So, HAC using legilimency probably couldn't get a verbal reason for lack of trust without a probe to raise "trust of HAC" in Hermione's mind, but once raised he would have been able to tell if she lied or detect any reasons that jumped into her mind that she didn't say out loud for strategic reasons... and not much more.

I could be wrong. "Word of god" might contradict me. But assuming I'm not, then my working model of the fic includes that HAC now knows, for example, that Harry has a deathly hallow (because Hermione would probably have consciously surfaced the most dramatic evidence that Harry totally trusts her when HAC asked about that stuff and that's pretty dramatic evidence). Given how many readers didn't even get that cycles of oblivation were being used on her I'd guess that something too optimized (to the point of silence) would be even less intelligible in text.

I guess a totally "optimized" oblivation/legilimency cycle could probably do a full loop within like 8 seconds and would just involve a "don't think of a polar bear" shout, reading everything brought up by that, then obliviate and repeat. We didn't see that happen at all. Either we didn't see it because it was impossible, or Eliezer didn't think of it, or Eliezer didn't think HAC would think of it, or it would have been too squicky and thereby violated the artistic permissions of the audience.

My bet is that this kind of manipulation would be impossible based on the in-story mechanics of legilimency and related spells... that the pragmatics of the process require a measure of indirection even with naive victims so that their eyes can't be closed, and their thoughts have time to percolate, and things only mentally accessible from within a specific conversational context can occur to them to be read, and so on.

the occlumency trainer harry hires is able to read deeply within harry's mind without a lot of trouble. I think thoughts are probably easier or harder to read based on how surface they are. Dumbledore made them think of something else so he wouldn't accidentally read anything private because of how EASY it is to read surface memories, not because thinking of something else prevents being read entirely.

There seem to be two forms of leglimency, one that requires an explicit spell and a wand, and can be performed by most wizards. That's what Mr. Best in MoR uses, and what canon!Snape uses while trying to each Harry Occlumency. The victim knows what's going on, but usually can't do anything against it.

The second one is the form that Dumbledore (and canon!Voldemort), which just requires looking into the eyes of the victim, and lots of training. This is the "stealth mode", and most victims don't notice the intrusion at all.

It was always my intuitive understanding that the first form allows you to dig deep into one's memory, wheres the second form only shows you what the victim is thinking right now.

Does that make any sense?

If I remember right, a moderately big deal is made of wandless magic in the last couple books of the canon.

It could just be a power difference. If wandless magic came with no penalties attached, you'd have to be mad to continue to use wands if you can manage wandless magic like Dumbledore can. It strictly dominates wands - you can't be disarmed nearly as easily. (And when we see wizarding children 'naturally' use wandless magic, isn't it weaker than what they can manage with wands?)

A big enough difference of degree can look like a difference of kind.

Two things, one: being more difficult to disarm isn't really as much of an advantage as it might seem. Remember, we have some idea of how magical combat works in MoR, and it seems to revolve around layers of active and passive defenses - during Bahry One-Hand, veteran Auror, v. Polyjuiced!Quirrel, the description went

According to the Defense Professor, the essential art of dueling consisted of trying to put up defenses that would block whatever someone was likely to throw at you, while trying in turn to attack in ways that were likely to go past their current set of defenses. And by far the easiest way to win any sort of real fight - Professor Quirrell had said this over and over - was to shoot the enemy before they raised a shield in the first place, either from behind or from close enough range that they couldn't dodge or counter in time.

If telekinesis-type spells (Accio, Expelliarmus, Wingardium Leviosa) are relatively easy to shield against, fights would tend to end by incapacitation rather than disarming whether you had a wand or not.

And two: interestingly, 'accidental magic' (used by wizarding children before they get their wands, generally in times of high emotion) is actually somewhat more impressive than what just-got-their-wands first years can do. Example: before he went to Hogwarts, canon!Harry once managed to get from standing on the ground to standing on the roof of his school without quite being aware of how he did it - the text seems to imply some kind of teleportation / Apparation, but it could have been self-levitation - either way, much more impressive than anything he could do for a while afterwards.

So? This is like someone saying, after scraping a violin for a few minutes, 'pfft, I can whistle more musically than this darn thing'. It's a tool, and like all tools, takes time to master, but when it does, you're much better than without the tool. (Think about how long it takes to learn a computer, and what one can do with it.)

Chapter 24: Machiavellian Intelligence Hypothesis: Act 2 ... The line of reasoning continued: Atlantis had been an isolated civilization that had somehow brought into being the Source of Magic, and told it to serve only people with the Atlantean genetic marker, the blood of Atlantis.

And by similar logic: The words a wizard spoke, the wand movements, those weren't complicated enough of themselves to build up the spell effects from scratch - not the way that the three billion base pairs of human DNA actually were complicated enough to build a human body from scratch, not the way that computer programs took up thousands of bytes of data.

So the words and wand movements were just triggers, levers pulled on some hidden and more complex machine. Buttons, not blueprints.

And just like a computer program wouldn't compile if you made a single spelling error, the Source of Magic wouldn't respond to you unless you cast your spells in exactly the right way.

The chain of logic was inexorable.

Under that hypothesis, accidental magic by wizarding children — otherwise without appreciable magic power, could be a Source of Magic initiated emergency "Help" spell.

interestingly, 'accidental magic' is actually somewhat more impressive than what just-got-their-wands first years can do.

Harry (in cannon) performs accidental magic during times of high emotion and when he's not able to cast spells (ie, before he has his wand or summer vacations). This is also true with Ariana Dumbledore, Snape, and Neville in each other occurrence of accidental magic in the series. In HP:MoR, wizards use the mana/muscle system for magic. It seems likely that magic can 'build up' if unused and release in an explosive (sometimes literally) fashion in the form of accidental magic. Furthermore, since nobody seems to intentionally use it, it must have a drawback; extreme draining of magic disproportionate to the effects seems like a logical effect.

Interestingly, both Tom Riddle and Lily Evans were able to consciously control 'accidental' magic as children. They both ended up the greatest spellcasters of their year. This would further reinforce the hypothesis that it extremely drains your 'magic' muscle, given that working out one's magic has been established to make one a stronger spellcaster.

Rather than two forms of legilimency, I thought it was a matter of the caster's facility with the spell.

In other words, it was my understanding that amateur Legilimens had to use their wand and the incantation in addition to eye contact, and with practice they could do away with the wand and word. That branch of magic is easily made wandless, perhaps.

That bit was textually sparse but my reading there was that in the fourth lesson where he pulled many secrets he was reading Harry's memories of having been read over a longer period and it raising issues and them talking out an acceptable resolution so that the teacher would keep teaching. Presumably Harry could bring the whole conceptual network up "above his surface" right off the bat just to get it out of the way on purpose, which seems to be implied by this line:

...you saw that we already had a long discussion about whether you were willing to teach me Occlumency, and in the end you decided to do it, so can we just get this over with?

When Albus read Harry early in the story to look for traces he asked Harry what Harry had recently eaten so as to prevent himself from reading anything private in Harry's mind. If words can be used to redirect attention to banal issues so that it is impossible for even Albus to see more deeply

I didn't interpret it that way. Rather, I interpreted it that Dumbledore didn't want to incidentally get data about any other thoughts, he just wanted to look for signs of prior tampering. In that limited context, he didn't want Harry to think about anything that wasn't Dumbledore's business. A skilled legilimens if they are trying might be able to still get more out of that situation.

But Quirrell was also there, and presumptively allied with Lucius and against Albus.

"If you don't tell him," Professor Quirrell said then, "I will, even if you fire me for it."

If Albus read Harry in front of Quirrell without doing something to prevent invasive reading being possible in principle then it would have given Quirrell much more ammunition to use in a complicated way. They actually did quibble over the matter, and the fact of the quibble (rather than a bigger deal) directly implies that both Quirrell and Albus had precise models of what was possible with legilimency under those conditions, and knew each knew, and knew what could be safely done and safely accused, and didn't bother to argue about bigger issues, where they mutually understood, and understood that each understood, and understood that Harry could verify, that the distraction had been sufficient to make it impossible for Albus to have engaged in profound impropriety.

Or that Quirrell had a precise enough model of Dumbledore that he knew he could only hurt his standing with Harry by accusing Dumbledore of things that Harry could easily learn were out of character enough to be improbable.

If he starts accusing Dumbledore of things he doesn't himself believe that Dumbledore would do, he could end up being discredited and then looking paranoid rather than wise and experienced.

Dumbledore's remark that "That was all I looked for" doesn't sound like something he would say if, while reading Harry, he couldn't have looked at anything else if he wanted.

I wonder whether the Tootsie Pop reference was a Leaning on the Fourth Wall hint to the readers or if we're meant to take that as Hermione subconsciously remembering what was going on? ("One hundred and eighty-seven. I tried it once." is kind of chilling, in that context.)

Or it could've been just a meaningless flippant remark, that too.

And 12 minutes per cycle? For the script given in the chapter, I'd peg it at more like 2 to 4.

Edit: Actually, I just though of a way to get an upper bound - the amount of adrenaline the human body can produce in 2-4 minutes is probably pretty sharply limited, right? Mr H&C presumably had to startle Hermione at the end of every cycle, so the physiological reaction would match up to the initial surprise and smooth over any discrepancies. I find it hard to imagine that "a rush of shock and fear hit her like a Stunning Hex over her whole body" more than five or so times without just leaving her burned out completely. (Not that she didn't seem pretty burned out by the end.)

The Chilling Implications you point out (how many licks does it take to get to the center of Hermione?) were totally lost on my consciousness until now. I wonder if that subconscious imagery had anything to do with why my brain produced that response from Hermione?

I think you're misreading the situation. From Hermoine's point of view, it seems like she's suddenly getting flooded with adrenaline. The truth is that she's had the same level of adrenaline in her body and is just being made aware of it. It's similar to how walking four miles then getting obliviated an hour back would feel like you've just gotten teleported and been hit with a jelly legs jinx.

The exact phrasing at the end of the cycle that happened onscreen was:

[...] the black mist evaporated away, no longer obscuring; she saw the face beneath, and recognition sent a jolt of terrified adrenaline bursting through her -

- she felt a momentary sense of disorientation -

- and then a rush of shock and fear hit her like a Stunning Hex over her whole body, she found that without any thought or any conscious decision her wand had leaped into her hand [...]

My interpretation, and maybe I am reading too much into it, is that it was necessary to give her a shock right before the Obliviation, because otherwise the physiological experience would be going from 'walking calmly down the hallway' to 'walking tiredly down the hallway,' which wouldn't jive with convincing herself she just reacted very quickly (her wand leaped into her hand).

Also, why else would you reveal your true face to someone just before you Obliviate them and show them a different, equally false appearance? Eliciting the reaction seems to be the obvious motive, and helps get around a weakness of Obliviation - that it only affects the neurological, not the rest of the body (hence Harry's signaling method of biting his lip).

I assumed that revealing your true face to the person would not ever be remember, so it wouldn't matter what you did. There's no reason to bother going into another room or even turning around (and risking them trying to run/hex you) to swap faces if you're just going to obliviate them anyways. It's just a result of being weary with the whole process.

These are only dry runs at cracking her password. You practice a dozen times until you succeed, obliviate her and let her settle down, obliviate her so she doesn't remember the settling down time, then do the successful attempt. The "most glorious destiny" attempt won't be what she remembers, but rather a seamless polished version after Mr HAC has confirmed it will work.

The final, final version will have her never even suspecting anything suspicious or having discontinuities like spinning around and wands leaping to her hands. Heck, it need not even occur at the same time, but rather a day later so she doesn't get suspicious of lost time. Or at least, that's what I would in the same position.

I agree. It was so obvious to me that Hermione was being Obliviated that when I read the instruction at the start of the next chapter I went back to see what I could be missing. It didn't occur to me that peope might not be getting it. And that was when it had ellipses.

comment by JoshuaZ · 2011-09-14T03:37:01.596Z · LW(p) · GW(p)

I'm one of the people who was confused by the Merlin thing and said as such in my review that I wasn't sure if it was lying or not. In that version, the Obliviation was a lot less obvious. My initial reading was that the entity in question was trying to appear (probably untruthfully) to have been testing Hermione previously and was now ready to reveal itself in its true, nice form. It even occurred to me that it might even have been its actual form with it finally happy that it could appear as a nice being rather than as some terrible mystery. I was in particular thinking of the part in the Chronicles of Prydain where the companions are shocked to find out that the nasty looking hags true form might actually be beautiful young women. In that text they call it out explicitly.

Still, the switch to the repeated ... made it really clear what was going on in a really blunt, squicktastic fashion. I have to agree with pedanterrific that you may want to be careful not to play to the lowest common denominator of ff.

Re Chp 35

I searched all the threads, and didn't find any mention of this. There's a hint in the conversation between Hat&Cloak and Zabini: namely, the fact that there is a conversation at all. Why does H&C need to talk to Zabini if he's just going to obliviate him anyway? Here's one possible answer: he needs some information from Zabini.

I don't think he needs Zabini's report on the conversation — partly because he keeps talking afterwards, and partly because there are independent reasons to think that H&C is either Quirrel or an agent of Quirrel's. (For instance, the "keyed into the wards" comment, as well as the fact that H&C exactly predicts Quirrel's reaction to Zabini's statement, and the fact that this statement ended up benefiting Quirrel.)

So what information does H&C need? Note that he tells Zabini, "The reward I promised you is already on its way to your mother, by owl." In other words, Zabini was clever enough to insist that his reward go to a third party, leaving someone around to remember that he's owed an award in case he's obliviated. H&C seems to me to be turning the conversation at every step towards Zabini's mother. Eventually, he receives the information that Zabini doesn't know how his mother persuaded her last suitor to marry her.

It's unclear why this information would satisfy H&C, but it does seem that he needs to take care of Zabini's mother in some way (obliviate her, probably), and that he's trying to figure out how difficult this will be. This seems reminiscent of Quirrel's later behavior towards Auror Bahry — he tries to figure out exactly what Bahry knows and what the other aurors expect so that he can appropriately memory-charm him.

Any thoughts on the matter?

I hope that doesn't turn out to be the reason for the conversation to have happened — it's a little unsatisfying. I guess another reason for H&C to need to talk to Zabini could be in order to use legilimancy on him. Presumably, in this case, to discover whether Zabini told anyone else besides his mother about H&C.

Edit: On reflection, this seems quite likely to me. H&C turns the conversation to betrayal, and if the plan is to use legilimancy on Zabini, then Zabini would need to be thinking about betrayals (and whether he has betrayed H&C) in order for the legilimancy to be useful.

I think you might be overthinking things. H&C keeps bringing the conversation around to the consequences of serial betrayal. One off-hand remark (the "keyed into the wards" comment) leads Zabini to think about his guesses as to who H&C might be. The Obliviation only comes after Zabini thinks to himself that no one gave him a chance to sell out H&C.

An idle bit of speculation, which has probably been brought up before, but it occurred to me that MoR Voldemort, being more intelligent than his canonical counterpart, may not have seen fit to stop at a mere 7 horcruxes. Why not simply make as many as (in)humanly possible, rather than adhering to some superstitious wishy-washy stuff about "7 is a powerfully magic number"? It is almost certain that the mechanics of horcrux-construction in MoR are different from those in canon (e.g. mind-upload rather than soul-splitting), so perhaps the limit that Canon!Voldemort faced (unstable soul-fragments) is not something that would be encountered in quite the same form as MoR!Voldemort.

To provide the merest scrap of substance to my speculation, I noticed that in Chapter 53 (TSPE, Part III), Quirrell states:

“Yess,” hissed the snake, “but do not underesstimate her, sshe wass the deadliesst of warriorss.” The green head dipped in warning. “One would be wisse to fear me, boy, even were I sstarved and nine-tenthss dead..."

The bolded interests me, partly because of something Dumbledore states in Chapter 61 (TSPE, Part XI):

"...Voldemort’s final avenue is to seduce a victim and drain the life from them over a long period; in which case Voldemort would be weak compared to his former power."

Slowly draining a victim's life and being weak compared to his former power is certainly what occurred with Canon Voldemort possessing Canon Quirrell--perhaps MoR Quirrelmort benefits from a similar arrangement? If so, the adjective "starving" certainly fits.

Now, we already know that Quirrelmort likes to play ironic little games with what he says--in fact, he admits as much himself in chapter 51: The lips twitched again, and then went flat. "Then I shall skip it. Mr. Potter, you sometimes make a game of lying with truths, playing with words to conceal your meanings in plain sight. I, too, have been known to find that amusing."

To return to the point, if hypothetically describing himself as "starving" falls into the same class of ironically veiled truth-statements Quirrelmort enjoys dropping from time to time (see ch. 49: "If only You-Know-Who had lived, you might have persuaded him to teach you some of the knowledge that would have been your heritage, from one Heir of Slytherin to another," or perhaps "Tell them I ate [the dementor]"--->"I am a death-eater", or again Harry had asked why Professor Quirrell couldn’t be the one to play the part of the Dark Lord, and Professor Quirrell had pointed out that there was no plausible reason for him to be possessed by the shade of He-Who-Must-Not-Be-Named), what might be the import of "nine-tenths dead"?

My thought was simply that "nine-tenths dead" might be a clue as to the number of Horcruxes MoR!Voldemort created.

If there are any negative repercussions of Horcrux-making in MoR, and I'm fairly certain there are, I should think Quirrell would have no good reason to make any Horcruxes besides the one. It's absolutely unreachable, why damage your soul any further?

Any reason(s) in particular that you're certain that Horcrux-creation would have detrimental effects significant enough that Voldemort would create only one, maximum? I assume it must have some detrimental effects, because otherwise, given a Rational Dark Lord armed with a time-turner, we'd be looking at Horcruxes proliferating as fast as he can make them. Tens or hundreds or thousands of horcruxes, one on every muggle device launched into or out of orbit, if he could manage it.

I notice that you seem to take for granted the existence of "souls" in MoR, which is far from certain. Actually I would rate the possibility as decidedly uncertain, since if souls and their attendant afterlife existed, it'd put quite a dent in the entire motivation for Harry's "conquer death and achieve immortality for everyone" program. And as prasannak noted, Harry has raised the alternate hypothesis that horcrux creation is less soul-fragmentation and more mind-uploading: "Maybe he found some way of duplicating the power of the Resurrection Stone, only he loaded it in advance with a complete copy of his brain state. Or something like that." (Chapter 39)

edit:

And I just remembered a brief exchange between Quirrell and Harry in chapter 46, which (to me, at least) hints at the existence of more than one horcrux. Quirrell asks Harry, hypothetically speaking, where he would choose to "lose something where no one would ever find it again." (I assumed he was being all ironic again and was talking about horcruxes.) Harry reeled off a list of about 5 possible hiding places, to which Quirrell responds "All excellent suggestions... But tell me, Mr. Potter, why those exact five? ...There is an interesting pattern to them.... One might say it sounds like something of a riddle." (Riddle? Irony overload.)

It just dawned on me that those 5 hiding places could only be clues to a riddle (the riddle of where Voldemort chose to hide all his horcruxes) if they didn't encompass the complete set of all horcrux hiding places, meaning that there are probably more than 5. Additionally, those 5 hiding places would only be good "clues" if they were themselves correct hiding places, from which further hiding places could be extrapolated based on some sort of shared similarity.

Do you mean Eliezer said that in an author's comment or something? If so I concede the point, though the text of MoR doesn't appear to me to support the existence of either souls or afterlife (even ghosts are less sapient than they are in canon).

I'm also doubtful about it from a story-telling standpoint, since if spiritual immortality for humans exists by default, it would make all of Harry's stated ambitions to achieve transhuman immortality in the material universe, for everyone, a bit pointless and perhaps even restrictive (that's a whole new world you never get to explore, if you never die). Also, since MoR has a certain didactic function, for Eliezer to establish spiritual immortality in the Rationality!verse would kind of take away from the impact of his anti-death and pro-cryonics sentiments.

As regards your comment about Rowling, I think in canon there's at least one piece of evidence strongly supporting the existence of an afterlife. In Deathly Hallows, during the "King's Cross" scene when Harry is AK'd into Limbo by Voldemort, Harry ostensibly meets the departed soul of Dumbledore, who tells him all manner of things (regarding his own past and the Deathly Hallows) that only the true Dumbledore would know. If one is particularly skeptical, one can write this off as total delusion on Harry's part (thus rendering suspect everything "Dumbledore" tells him), but that would go completely against the spirit of the story.

Yeah, I worded that poorly.

Blocking the Unblockable Curse.

This is mostly related to canon, but also a bit to HPMoR.

I've always wondered why the killing curse counts as "unblockable". In "Order of the Phoenix", Dumbledore blocks it by moving a statue in its path. Seems to work nicely. There is other evidence that solids stop the killing curse -- if it went through it, you could accidentally kill somebody behind a wall when missing your target. Prof. Moody would surely have mentioned that danger when talking about the killing curse, if that was the case. So you could carry around a steel plate strong enough to block the curse, and quickly move it into its path. Not easy, but possible.

There are also several instances where simple spells conjure animals (I remember bats and small birds). I wonder if you could simply conjure an animal into the way of the killing curse. It might need to have a minimal size to work, but a powerful wizards should be able to do that.

I also wonder if there are ways to combine charms: one detection charm that triggers another one. For example one that detects killing curses, and enables apparation or a portkey.

So, one proven way to block a killing curse, one conjectural, and another conjectural way to escape it. I can't believe the wizards still call it "unblockable" :-)

I'm pretty sure that 'unblockable' is meant to mean it was the only magic known to have no counter-effect, or counter-spell. Now Harry has discovered the true Patronus charm is the counter spell to Avada Kedavra. It makes sense when you think about it, which I'm sure is why Eliezer included it in the first place. The Dementors are voids of nothingness, into such nothingness tumble all living things once their life is extinguished (according to present evidence, anyway); in other words, the Dementors are parts of Death, but are not Death Incarnate (which can be summoned according to a Dark Ritual Quirrell read tell of as a spritely young lad). Thus, if the Patronus charm has the ability to repel a piece of Death, then in accordance with magic's apparent system of dualities, the Patronus charm must represent the opposite of Death: Life.

All but Harry cast their Patronus using memories, figments of the mind based upon reality; because they only conjure a thought reminiscent of all life can be, they can only manifest a fragment of life force to shield themselves from Death - an imperfect shield, permeable to Death.
Harry recognizes the two poles of reality: Death, or absence - and Life, or presence. Harry brings to mind all that reality really is to us, namely all that a life can ever possibly experience, and pushes that in the face of the part of Death that is Dementors.* Harry has this ability because he strives to and greatly succeeds in deceiving himself of nothing (he's not perfect - yet); through rationality he is able to have an accurate enough map of the territory that his conjured thought actually is a picture of all life can be, and so he can manifest the entirety of his Homo sapiens sapiens being. His Patronus not only represents but is pure life force, so it can overwhelm and obliterate imperfect representations of Death id est Dementors.

Likewise, as both Dementors and animal Patronuses are imperfect representations of their respective pole, their effects more or less cancel; an animal Patronuses' ability to repel a Dementor is in apparent proportion to its representative accuracy. Harry's true Patronus is the the form of Life itself, and so he can destroy Dementors and cancel Death; Dumbledore accepts most of the Life dimension of reality, and nearly all of the Death dimension of reality, and so his representation of Life, his Patronus, is the strongest and brightest yet mentioned.

Now comes the tricky part of this hypothesis. The Killing Curse is equal to death in that if struck by it, assuming no inherent rule of magic regarding altruistic protective love interferes, you will die. The true Patronus has demonstrated the ability to overpower and destroy imperfect representations of Death, as it is the duality opposing Death in true form. However, the Killing Curse and the true Patronus cancel, so it must then follow that the Killing Curse is Death in true form, but not Death Incarnate.

However, this theory is completely blown away if the true Patronus doesn't cancel the Killing Curse at all, that Harry blocked Quirrell's Avada Kedavra merely by effecting an interaction of their magic. Whether the true Patronus can truly block the Killing Curse remains to be seen.


*From what I've gleaned from the text, I do not think Harry's statement, "I think of the absolute rejection of Death as the natural order [paraphrased]," accurately reflects his thought processes preceding the casting of the true Patronus; to reject Death is to acknowledge it, and I don't think Harry acknowledges Death at all when casting the charm. Furthermore, I do not even think it possible to cast the true Patronus when thinking of Death at all. When casting the charm, Harry calls to mind all that Death isn't, and all that life is; he thinks purely of life, with not even a single shard of a thought of Death in mind.

As an aside, I find it particularly clever how in contrasting everyone else in the wizarding world, or agents of general humanity, with Harry, an agent of rationality, Eliezer characterizes animal Patronuses as akin to the self-deceptions and biases of most of humanity, and the true Patronus as akin to the power earned through the diligent application of rationalist techniques to everyday life, through elucidating the difference between animals'\ capacity for understanding and human capacity for understanding.
\Excludes humans as a subset; the sentence becomes awkward otherwise.

My assumption was always just that the "summon death" bit referred to creating a Dementor, and that they are much more directly about death than simple nothingness. This isn't necessarily implied by the text, but it seems the more likely explanation.

And yes, you can definitely argue with the author about their own characters, to a certain extent. (I.e., "He'd never do X, Y is way more like him!" okay, "Harry is actually a 57-year-old woman!" not okay). You're well within the lines here.

... the most terrible ritual known to me demands only a rope which has hanged a man and a sword which has slain a woman; and that for a ritual which promised to summon Death itself - though what is truly meant by that I do not know and do not care to discover, since it was also said that the counterspell to dismiss Death had been lost.

  • Chapter seventy-nine, HP:MoR

I can see your interpretation, but Quirrel's commentary does not lend it credence. He does fear Dementors, or rather their effect upon him, but - no, your interpretation holds; regardless of how high a probability there may be of the spell merely summoning a Dementor, the inability to dismiss what's summoned leaves too high a risk of freeing something worse.

Though I would think Quirrel would clearly express those concerns over opting to speak warily and vaguely of the ritual - and I think it out of character for him to not have thoroughly contemplated it.

You need to remember how wizards think. If the killing curse can't be blocked by spells, then it simply can't be blocked. They mean that if you use it in a duel, it doesn't matter what sort of shield spell your opponent has up, it won't work, and so the spell isn't very sporting and therefore is unforgivable.

Chapter 76: "And that's why I can destroy Dementors and you can't," said the boy. "Because I believe that the darkness can be broken."

This is interesting, because it touches upon a thought I had about the Dementors back in Chapter 45. In canon, Dementors are manifestations not of death or even fear, but of despair. (I believe Rowling has said she drew upon her own experiences of depression.) That's why chocolate helps, why they generate feelings of hopelessness, why they take away happy memories and leave unhappy ones, and why their ultimate power is to put people into a coma rather than to kill them. None of this makes sense for a manifestation of death.

But Harry's response would work either way. A happy memory, a pleasant thought, can shield against despair, but it can't destroy it. Hope, on the other hand, true grim hope – the belief that things can be made better and, crucially, the unshakeable determination to make them so, not by thinking 'wouldn't it be nice if…' but by knuckling down and solving the insoluble problem – is the only true cure for despair. And that sort of hope, which Harry shows, is actually pretty hard to hold truly, which would explain why almost no-one else has found the same way that Harry has.

I don't believe this was Eliezer's intention. Harry's views on death are far too close to Eliezer's own as shown in http://yudkowsky.net/singularity/simplified for me to feel that the Dementors are intended to be anything else. But I quite like my interpretation. Aside from anything else, since that sort of hope can be reinforced by being shared (enhancing both resolve and the feeling that the task is possible), it leaves open the possibility for a Patronus 3.0 by group-casting.

I think what Harry says is heartfelt, but it's also a decent false trail to prevent Dumbledore from accidentally working out the secret and losing his ability to cast a Patronus.

Not that Dumbledore necessarily needs that. He's in a great position for doublethink: he can presumably use the Pensieve, label the memory "the secret of dementors and the Patronus charm," then Obliviate himself. Locking the basilisk away in a secret chamber, if you will.

I don't know about chocolate, but bad memories are definitely scars you get from death. And what I suspect triggered the idea in Eliezer's mind to make Dementors be about death is the idea of the Dementor's kiss, because of the old metaphor "kiss of death".

In your story they are corpses. In canon, they're green humanoid monsters wearing hooded robes, that represent despair. Considering Rowling's own pro-death position, I don't think it's likely she would have deliberately created enemies that were supposed to be the physical embodiment of death (although the movies showed dementors and death as looking nearly identical). Given the changes I saw you make to them in order to make your point, I assumed it was just something you were changing completely from canon. Apparently I was wrong. Did you think of dementors as representing death while reading Prisoner of Azkaban, or is it an idea you developed later?

Despair? I thought JKR mentioned depression, not despair. And the dementors are grey, not green.

And JKR's own experience with depression was after the death of her mother -- so the "death causes depression" is similar in content to "Dementor destroys all positive emotions". There's no reason why JKR couldn't use imagery of death in combination with her emotion.

In the books, an afterlife exists. But the soul-destruction, the true death, is what the Dementor seems to cause. Again -- if JKR's mother had just died, her most depressed thoughts about it would be the ones that involved thinking about the true death of soul-annihilation (the Dementor's kiss), not an afterlife.

Green? No. From the American edition of PoA:

A dead, slimy hand slid out from under the cloak[...]Then it raised both its rotting hands -- and lowered its hood. Where there should have been eyes, there was only thin, gray scabbed skin, stretched blankly over empty sockets. But there was a mouth...a gaping, shapeless hole, sucking the air with the sound of a death rattle.

And for the first appearance of a dementor Rowling talks about drowning. I don't know about the skin over the eyes, but the rest of it explicitly points to death.

That's backwards. I suppose experiencing the death of someone close to you could leave a mental scar in the form of a bad memory. But that's hardly the definition of a bad memory. Nor is a painful memory an inevitable outcome of someone's death.

Well I am in HMPOR withdrawal so I will post an idea that I have about the origin of the "unverbalizable fear" that Harry has while under the sorting hat about going to Hufflepuff where he will be happy. This idea is based on the few descriptions of the relationship between harry and his father in the early chapters

I was going to post the excerpts in this comment, but it is quite a bit of content so I will abstain for now. If someone wants me to post the excerpts I will. For now suffice it to say that Harry does not feel respected by his father and the only positive feeling that his father is said to display towards Harry is pride.

His eyes glanced over to his father Michael Verres-Evans, who was looking stereotypically stern-but-proud

You might say that his father dropping everything for a last minute book buying spree was a very kind thing to do. Indeed Harry himself says that his dad is "awesome" because he buys him books, and uses the memory later when trying to cast the patronius charm. However, considering the lack of respect and affection that Harry's father shows I have to ask if the book buying spree was really for Harry. It seems more likely to be an attempt to help Harry "be all that he can be" not for Harry, but for himself. So he can continue to feel proud about the achievements of his child.

Children need the expression of love and affection from their parents in order to feel secure. If all Harry can get from his father is pride then it will be very important for him to maintain it. I submit that Harry's unverbalizable fear is an unconscious fear of abandonment(death for most of human history) if he loses his fathers pride by choosing the path of happiness over achievement.

Consider that the school is full of 11-18 year olds with access to weapons of mass destruction and it seems to me that the apparent safety of the place for the past 50 years is due to luck rather then anything inherent in system.

Perhaps luck is inherent in the system. The canon storyline does include a literal luck potion, so similar things are plausible. They also have and use a seer, and short-range time travel. The latter two could be used in ways that prevent deaths without a corresponding reduction in close calls.

From Ch. 36:

Hermione's mother had looked very alarmed, and Harry had quickly interrupted and done his best to explain that all the spells were stunners, Professor Quirrell was always watching, and the existence of magical healing meant that lots of things were much less dangerous than they sounded

Now the "all spells are stunners" isn't always true, but for the most part (at least in canon) the hexes they use aren't really powerful. But I think that most of the safety record is due to the latter two factors. How many times in canon have characters had injuries that would have required many months of physical therapy in the real world, and been fine a week later?

All external threats (without internal assistance) for a start. As for internal threats there is the old "If you kill your fellow students with either spells or via garrotting them with your shoelaces like any mortal could do then Dumbledore, Snape, Quirrel and McG will @#%@ you up!", and anything less than actually killing them and the staff can heal you.

None of this helps vs the "Students learn transfiguration. Everybody dies." problem but that was outside the scope of authorial comprehension.

In my understanding, the wards serve mostly two purposes: prevent harm from the outside (by mostly isolating Hogwarts magically from the outside), and analytical wards that inform the school authorities if something really bad happens.

So if you want to murder someone inside of Hogwards, you face the problem that the murder is immediately detected, and then you're sealed off from the outside -- the chances of escaping aren't very high.

You are right that the wards don't seem to prevent any accidents, but it seems that most "school magic" doesn't go horribly wrong without prior warnings. For example in potions, people seem to know which potions are dangerous, and those are only done under supervision.

My former high school has been around for 43 years now, and has never had a mass murder, and had quite a few more students than Hogwarts does. Columbine-level events are nearly unheard of, even though they wouldn't be much harder to execute than the hundred-pounds-of-bleach plan. The wards are probably just there to prevent outside attack from political opponents, and the children are assumed to be as well adjusted as anyone else in society.

One: I wasn't thinking in reference to Hogwarts students, just wizards in general. (Hence 'Diagon Alley' rather than 'the Great Hall'.)

Except that the "hundred pounds of bleach" plan requires only a single, irreversible action, so it's more like pressing a button.

It doesn't take a genius on the level of Voldemort to transfigure a hundred pounds of bleach (or name your poison) into air and release it inconspicuously in Diagon Alley.

It kind of does.

It really doesn't. They teach transfiguration to the children from about 8 years old and some of them do not completely fail. They tell the students a bunch of things that are really dangerous to do. There are many people below the level of Voldemort who have both the knowledge and skill to kill people effectively with transfiguration if they so desire. It really isn't that much of a genius feat of creativity.

In how many fanfics is anything like this suggested?

Relatively few fan-fictions are based around the crude exploitation of basic magic for the purpose of terrorism. This says a lot more about what makes a good story than about how hard it is for average wizards to play terrorist. Significant plot arcs about magical terrorists sound cooler if they use fancy dramatic magic that sounds mysterious and hard to acquire rather than the simplest thing that would work.

They tell the students a bunch of things that are really dangerous to do.

They go further than that: the standard textbook includes a horrifying animated photograph of a murder victim. The idea that Transfiguration can be used as a weapon is taught in the very first class session.

In the wood-shop class which I took when I was a year or two older than a Hogwarts first-year, we were taught that the tools are dangerous. We were taught that you can cut your arm off with a bandsaw if you behave foolishly near it; and that if you lower the drill on the drill-press against your hand, it will put a hole through your hand. However, we were not specifically taught about the possibilities of shop tools for intentional murder. It was assumed that any accidents would be just that: accidents.

Now, Transfiguration is more dangerous than shop tools; Transfiguring a brick to air or water could sicken or kill quite a few people, whereas a belt-sander is really only dangerous to those within shoving distance. But a shop-class student casting around for a weapon would probably seize upon a chair-leg or two-by-four much more readily than a saw-blade. The Transfiguration student — having been explicitly instructed that the art has been used to intentionally kill — would much more likely bring that to mind.

I would use Aluminium, in small amounts. It wouldn't so much be terrorism as it would be counterintelligence. Literally. Do some experimentation (on political prisoners) first and then some calculations on air dispersal concentrations and work out how much the human body can absorb via untranfiguration without being detected. Then proceed to provide a chronic internal dose of Aluminium to select enemy targets over an extended period. The slow but steady cognitive decline would have no apparent source and would be noticed only after it has been resulting in poor decision making for a long time. Just what you need when you are planning a magical war.

Aluminum sounds like it'd have a long half-life and leave elevated levels in the blood and hair for a long time - and so is easily tested for.

That's rather the point. Supplying a dose at a rate that is below the ability to detect at the moment of the untransfiguration causes the aluminium to build up in the brain over the long term and result in a slow but steady decline in function without anything to prompt attention unless the decline in function itself is noticed - and that sort of introspective access is rare.

Lots of drugs damage cognition and disappear quickly; maybe scopolamine, but there are probably better suggestions.

Naturally drugs are the first things to consider - or more precisely the more extreme potions and the venom of exotic magical beasts. But drethelin was considering the easiest option - that of just getting a bunch of easily accessible matter and transfiguring away. Just grabbing an aluminium can and dispersing it once a day seems like the best choice as far as easily accessible mundane materials go. Naturally if we have already ruled out bleach the more complex human poisons are way out but what do you think would be the best magical poison/venom? Basilisk fang has potential. Spiders could be fun. But now I'm speculating about transfiguring philosopher's stones. It seems the HPverse one only works on metal but if there were a related midaslike substance that was less specific it'd be rather hilarious to turn all your enemies to gold in a flash by standing upwind.

  • and so is easily tested for.

And yet isn't. Even muggles who know what Aluminium is beyond "weird muggle softdrink cans" and know what the effects can be don't bother to test for Aluminium even when signs of toxicity start appearing.

This rather seems to apply to the weaponized transfiguration in general. Compared to identifying and removing Aluminum that is dispersed into the cells of the brain - never mind trying to fix existing neural damage - is far more difficult than defending against the whole class of transfigured gas attacks.

There must be better substances to use!

That particular tactic is, of course, an optimization within the domain "transfigure arbitrary commonplace solid". Did you consider the alternate substances discussed in the comment to which you are replying? Are there some superior options to those that you would suggest?

If transfiguration can only result in non-magical substances, then science would help to transfigure to CBW agents - ending up too close for comfort. Wards cast in transfiguration classrooms and dormitories to detect intent to violate transfiguration rules would catch those, a wise expansive interpretation would catch the worst I can think of (critical mass of fissile material => will generate gas). The Hogwarts House system should force conformity and channel risk-taking into known paths. If failing to attempt homework would lose points, depression and mental illness could be caught early. Would the wizarding world have something of the culture of manners of the Diamond Ages's Victorians, with wards and parlours working as firewalls and time for threat assessment/decontamination?

That doesn't make much sense; Myrtle was described as the first fatality in a long time, which is why it was so shocking and nearly closed down Hogwarts completely - the consequence which caused Tom Riddle to back off and seal off the basilisk again. 5 decades is quite long enough for this to be a somewhat bizarrely low rate.

On the other hand, wizards are described as having very long lives on average, which is not very consistent with a high accident or suicide or homicide rate overall, and Hogwarts is a pretty small school, as the estimates go. Add in the claims of extraordinary Wizarding physical resilience (book 1, IIRC), and maybe that's enough to give the very low death rate.

Myrtle was a murder from an unknown assailant who could evade the protective wards of the school, and probably murder at will again -- "there's an uncaught murderer among your children" is a much more scary thing than an accidental fatality of the sort that I assume are still occasionally happening in other magical schools through negligence/etc.

When there's an accidental poisoning because some kid tried to brew an anti-acme potion, parents can just advise their children not to ever try anything as foolish as that -- and they even have the accidental death of the other kid as a warning for such foolishness...

Chapter 49:

Professor Quirell [sic] leaned back, smiling. "This is not a puzzle you can solve on your own, Mr. Potter, so I will reveal the answer. Over the winter holiday, I was alerted to the fact that the Headmaster had filed a request for a closed judicial panel to review the case of one Mr. Rubeus Hagrid, whom you know as the Keeper of Keys and Grounds at Hogwarts, and who was accused of the murder of Abigail Myrtle in 1943."

"Oh, of course," said Harry, "that makes it downright obvious that I'm a Parselmouth. Professor, what the sweet slithering snakes -"

"The other suspect for that murder was Slytherin's Monster, the legendary inhabitant of Slytherin's Chamber of Secrets. Which is why certain sources alerted me to the fact, and why it caught my attention sufficiently that I spent a good deal of bribe money to learn the details of the case. Now in point of fact, Mr. Potter, Mr. Hagrid is innocent. Ridiculously obviously innocent. He is the most blatantly innocent bystander to be convicted by the magical British legal system since Grindelwald's Confunding of Neville Chamberlain was pinned on Amanda Knox. Headmaster Dippet prompted a student puppet to accuse Mr. Hagrid because Dippet needed a scapegoat to take the blame for the death of Miss Myrtle, and our marvelous justice system agreed that this was plausible enough to warrant Mr. Hagrid's expulsion and the snapping of his wand.

In canon, Hagrid had brought the giant-spider Aragog at around the same time -- and it was thought to have accidentally escaped his watch and murdered Myrtle. (so it was accident/criminal negligence on the part of Hagrid, murder on the part of Aragog)

If I remember right, it's implied that botched Transfiguration is a painful way to go -- it's compared to a severe illness. If its consequences are sufficiently well-known and unpleasant, it could be that it's not attractive as a suicide method.

According to a random Google first-page result, the annual suicide rate amongst teens is about 0.01%. While HPMOR's Hogwarts has a higher population, in canon (Word of God, really) the population was around 100 students per year, which suggests we'd see a teen suicide at Hogwarts about every century.

Rough figures say 20% of teens attempting suicide end up killing themselves; assuming all Hogwarts attempted suicides are successful, you'd still only have one every 20 years. And I'd suspect teens would be less suicidal at Hogwarts, and despite warnings would not try effective things like transfiguration very often.

Except that students stay at Hogwarts for 7 years, not one, which would put the suicide rate at Hogwarts at one per 14 years, not one per century (if wizards commit suicide at the same rate as muggles). If you assumed that Wizarding suicide attempts were 5 times as likely to be successful, that would put the rate at one suicide every 3 years.

Of course, it's entirely possible that the wizarding resilience to illness and injury also makes them more resilient to mental illness, and that's why suicide rates are lower.

I've been reading a chapter of MoR to my girlfriend every time we go to a park, and we just got up to Chapter 39. Two thoughts:

  1. It's fun to try to imitate a long series of random noises with your mouth alone in a public place.

  2. Sarah's immediate reaction to the first part was "Why doesn't he just ask Harry for a Pensieve memory of his conversation with Lucius? Dumbledore doesn't use notes." I can't see why not either. My first reaction was that Pensieves haven't been referenced in MoR yet and might work differently, but I was wrong; Draco's going to use his memory of Harry's first date to blackmail him.

The exact details of memories are malleable. It may very well be that pensieves in this setting can only recover what the person remembers not what they actually experienced. It may be that this could still be useful for interrogating less disciplined minds who can remember details but not realize they do, but Dumbledore may think that if there were any specific details that were important enough Harry would in fact remember them.

comment by pedanterrific · 2011-09-27T21:18:16.492Z · LW(p) · GW(p)

Another example would be Draco, to Harry, in Chapter 7:

"The courts use Veritaserum, but it's a joke really, you just Obliviate yourself before you testify and then claim the other person was Memory-Charmed with a false memory. If you've got a Pensieve, and we do, you can even get the memory back afterward."

And that's a very good point. I can't quite tell whether Dumbledore picked up on the mistake that Lucius made, just from Harry's memory - the only reaction we are directly told about is

Dumbledore's face had grown more remote as Harry went on, and at the end there was a look of ancientness about him, a sternness in the air.

"Well," said Dumbledore. "I suggest you take the best of care that the heir of Malfoy does not come to harm, then. And I will do the same." The Headmaster was frowning, his fingers drumming soundlessly through the inky black surface of a plate inscribed with the word Leliel. "And I think it would be most extremely wise for you to avoid all interaction with Lord Malfoy henceforth."

and then the conversation switches tracks. If Dumbledore did get the subtext just from Harry's (described, offscreen) verbal recollections, then the lack is just a minor puzzling detail; but if he didn't, when he most certainly could have from the inhumanly perfect reproduction of a Pensieve, failing to use one seems a critical flaw.

In canon, they can--Harry spends much of the sixth book exploring memories from many different people, all in the same pensieve. In MoR, Draco says "we" have a pensieve, implying there's a Malfoy Pensieve, where an "I" would imply that his and his dad's are separate.

I was just wondering: does anyone else hope Eliezer fleshes out Magical History? I find it a pity that we don't get to see how Magical Britain became what it is now. I mean, so far he's reflected (very broadly) on the current political situation through Draco, but he's continued to keep us in the dark about Voldemort's rise to power, the situation that led to that, the circumstances surrounding the beginning of magic (as a technology, since Harry has confirmed that the rules for spells aren't natural laws), the founding of Hogwarts ...

So, which do you all think are most important for Eliezer to touch upon? Can you think of any others you want to see?

Also: I know that wizards generally ignore muggles, but they are another entire civilization, with documentation of their history, living in secret right next to the Muggle society. Wizarding history could provide a lot of insight into Muggle history because of how the two are so closely related.

Eliezer has already mentioned things like Atlantis. History would probably play a role in finding out how magic works in general. Harry, from a political perspective, would do well to learn how the situation arose, and it may be an opportunity for Eliezer to set up an Aesop.

And it wouldn't necessarily change history. The muggle world as it is in canon is very similar to how it is in the real world, down to things like Playstations, yet Rowling invents a wizarding history that manages to not change much. All of the science Eliezer has mentioned is historically accurate to the year. It's not a stretch to say that the only part about HPMOR that is an alternate universe from canon is wizarding history, because even the existence of a wizarding world in canon didn't manage to change much.

Of course, this would be impossible to discuss in-universe without many-worlds magic. Harry can't find out why the existence of a wizarding world has not changed history if, from his perspective, there was no other "reality" for him to compare it to that he can actually draw evidence from.

However, wizards having their own history means they have their own documentation of that history. This means there are far more primary sources that may have been magically preserved, and muggles could, in the future, use these to learn more about their own history. They might even be able to settle historical debates that have gone on for decades, like what the actual pathogen that devastated Europe during the Black Plague was (since there is significant controversy over whether it was in fact the bubonic plague). Not to mention the existence of things like Pensieves. Magical historians are comparatively spoiled rotten when it comes to primary sources of historical events.

So the implications would be that, instead of changing muggle history, muggles would be more knowledgeable about what actually happened.

His testimony and memories would still be considered primary sources by historians. I don't think there is such a thing as a zeroth source.

It would seem to only apply to Flamel and then only when considering his past self in the first person rather than the abstract Me_1500 sense.

For things that canon changed about Muggle history, try Wikia:Mistakes in the Harry Potter books. (Most of that is irrelevant continuity errors, but some of that is contradictions with the real world.) Also see remarks about calendars in the HP Lexicon timeline.

I'm interested in discussing the world Eliezer has created. Its alternate in obvious and subtle ways. Obviously, in this world both Harry and Quirrelmort are rationalists, but lots of other elements have changed.

-Dumbledore seems more changed by war than his book incarnation, to the point where he is making some obviously bad choices that have impacts on the school -The school is a more dangerous place than it was in the books. By this, I mean that in books 1-4, despite some hijinks, the actual danger was pretty darn low- in first year Harry had to actively try to get into mortal danger (ignoring some deeply unsubtle assasination attempts by Quirrel). In particular other students are never a danger to each other, yet theres a strong implication that here fights really can escalate- or at least that was the attempt with the Heromione arc. This is probably due in part to Dumbledore's approach (I don't believe that the 'Dore of the books would have tolerated such an escalation at all), and the beefing up of Slytherin house, and the Malfoy's in particular. While Lucius Malfoy was clearly a powerful individual in the books, his manipulations were fairly clunky, and nowhere near as subtle as portrayed here.

I think I need to have it in my head that many of the characters are subtly different here, because sometimes I read their portrayal as mocking the attitude in the books, and while sometimes that IS whats happening, sometimes its just because the characters aren't quite the same.

We assume he's competent because Dumbledore keeps referring to him as competent, but Dumbledore does have a motive to exaggerate his enemy's power. He constantly uses Lucius as an excuse to not do something, and he flat out tells Harry early on that weakening Dumbledore strengthens Malfoy.

But Malfoy is in over his head. Every time we see or hear from him, he's getting something wrong, being ineffectual, or being publicly humiliated. By contrast, he seems pretty darn effective in the books. His scheme in Chamber of Secrets was simple and robust enough to work, and even with Harry repeatedly being in the right place at the right time it still ends with the Weasleys discredited and the Malfoys untouched. (Edit: Sorry, misremembered. He goes after Dumbledore prematurely and loses. Good scheme apart from that, though.)

His main obvious difference from canon is the way he's raised his son.

In part 7, Michaelos observed that Dumbledore blames himself for Harry being left with his evil stepparents, and wrote the comment on Lily's musing on modifying the (D&D-style) Eagle's Splendor potion in her text book while she slept.

Ch 1. "And Lily would tell me no, and make up the most ridiculous excuses, like the world would end if she were nice to her sister, or a centaur told her not to - the most ridiculous things, and I hated her for it. ... "Anyway," Petunia said, her voice small, "she gave in. She told me it was dangerous, and I said I didn't care any more, and I drank this potion and I was sick for weeks, but when I got better my skin cleared up and I finally filled out and... I was beautiful, people were nice to me," her voice broke, "and after that I couldn't hate my sister any more, especially when I learned what her magic brought her in the end -"

Perhaps, the brighter Lily, child of the enlightenment, growing up in the technological optimism of the 60s had determined to help her sister, and minimize the risks as she understood them. Giving Petunia the potion being a major change in the time line. Dumbledore may have been trying to prevent that.

Hm. Quoted in the linked post is the fact that Dumbledore's suggested revision to the Potion of Eagle's Splendor (the one that would end up making the imbiber sick for weeks, as happened to Petunia) was, specifically, replacing blueberries with Thestral blood. Now where else has that come up recently?

And Harry knew, now, that the concealment of the Cloak was more than the mere transparency of Disillusionment, that the Cloak kept you hidden and not just invisible, as unseeable as were Thestrals to the unknowing. And Harry also knew that it was Thestral blood which painted the symbol of the Deathly Hallows on the inside of the Cloak, binding into the Cloak that portion of Death's power, enabling the Cloak to confront the Dementors on their own level and block them. It had felt like guessing, and yet a certain guess, the knowledge coming to him in the instant of solving the riddle.

Considering that by the time he annotated Lily's book, Dumbledore had certainly had around thirty years to study the Elder Wand (which canonically has a Thestral tail-hair core), and may or may not have already examined the Cloak of Invisibility as well, this certainly seems suggestive of something. I've no idea what, though. ("Charming as death" doesn't seem like much of a compliment.)

I think that the new information 78 would give us to discuss ought to balance out the cliffhanger, no matter how large.

Also, I wonder if Harry might use the Headmasters conclusions about the return of the Dark Lord to request private lessons. Most likely not Horcrux-related lessons, but similiar to what Ron and Hermione expected Dumbledore to teach him in Canon. In this universe Love is certainly not Harry's Deus ex Machina, so Dumbledore ought to want him to be more competent in Battle Magic.

Just reread chapter 40.

"Which is why the Resurrection Stone is not the most valuable magical artifact in the world," said Harry.

"Precisely," said Professor Quirrell, "though I wouldn't say no to a chance to try it." There was a dry, thin smile on his lips; and something colder, more distant, in his eyes. "You spoke to Dumbledore of that as well, I take it."

Sounds to me like Quirrell had never heard of the resurrection stone before this conversation. Later in the chapter, it becomes apparent that he has never heard of the deathly hallows symbol. After Harry shows him the symbol, he excuses himself and cuts short the outing. Perhaps he has seen the stone before and is running off to find it? His ignorance fits with canon, where he uses the Peverell ring (with the stone inset) to make a horcrux.

From Chap 26

The key to a puzzle is often something you read twenty years ago in an old scroll, or a peculiar ring you saw on the finger of a man you met only once.

Possibly Voldemort made the Resurrection stone/ring into a Horcrux while killing his 'uncle'.

Later in the same chapter, Quirrell suggests that he's made Bacon's diary into a Horcrux.

"Oh," said Professor Quirrell, "don't worry about a little rough handling. You could toss this diary in a fireplace and it would emerge unscathed. In any case, I await your decision."

In canon, one of the main properties of a Horcrux is that it is indestructible by ordinary means, but since Quirrell has only 'recently acquired' this, it might just be charmed? Or would it be a Horcrux of Quirrell, rather than of Voldemort? Not sure...

Just because Quirrell says that he recently stole it does not mean it is true. Telling harry that it is stolen property is a good way to make sure he keeps it secret without causing any suspicion about the nature of the book. I think that the diary is a horcrux and another attempt to turn Harry over to his dark side permanently.

Cross posting what I wrote on TV Tropes

'm pretty sure i've figured out quirrelmorts plan for harry and magical britian. To TLDR it for you guys, hes going to train harry as a caesar, and use harry as a figurehead/puppet to force magical britian into a war of conquest with the rest of the magical world, probably selling it as a world wide war on dark wizards. Then once england owns the wizard world, they own the entire world since you can't fight invisible mind rapers.

Viewed in this context all of his actions start making sense. Harry is a very well known figurehead and a natural leader for magical Britannia to unite behind. Suddenly quirrelmorts speech of uniting magical Brittan under one person (harry) makes sense, once you've imbued all the power into a single leader its a lot easier to effectively run a war, as well as hurting harry's main competition for power. His first step is to go to Hogwarts, the most important place in england. He organizes it so that he can get away with blatantly improving the combat effectiveness of all the Hogwarts students there, developing and show casing the future generals and officers of the later wars. Also because those generals and officers will develop followers, all he has to do is gain influence over those people and he gains all of their followers as well. He also gets to develop his own Caesar, Harry. Hes already said that power in the magic world flows from strong wizards and their followers.

Then he convinces harry to undertake a war against the magical world. He points out that it will impossible to get rid of things such as the power of the noble houses and Azkabhan without taking power. He also points out to harry that if he wants to raise the living standards of the muggle world he will need a united magical world behind him, something that he will be unable to do by peaceful means since he will first need to exterminate all of the dark wizards. With both harry and quirrelmort on the same side with technology they would be able to both curb stomp other countries and administer them effectively.

Then with Harry's participation, he puppet masters a civil war in another country and gets magical England to step in to save the country, and get harry/draco appointed/showcased as wonderful warriors. They then use this power to keep taking over more and more of the real power in england. Then you start administrating the new country as a vassal state, raise more recruits, get a bigger army, rinse and repeat until they own the magical world. Then with the magical world united they own the muggle world since lets face it, you can't fight a foe that can turn invisible and mind rape your leaders.

And of course since england is ruling the world as an empire, and harry is ruling the world as caesar, and quirrelmort has his hooks into harry, quirrelmort now rules the world. Or at least thats what my plan wold be if I were quirrelmort.

Also on rita skeeter, they either memory charmed her into believing everything herself, or imperiused her into doing so, or simply used the polyjuice potion to turn it in themselves.

To be honest that passage didn't strike me as strong enough to warrant inventing a fake black box.

This seems far too long-term for the purposes of Eliezer's story. The only way a plan of this detail would make MOR better is if we actually got to see it acted out, and I cannot imagine Eliezer not wrapping up the plot before Harry is old enough to rule. He's certainly not going to fast-forward through the majority of Harry's Hogwarts time.

No, I think Quirrelmort's plan is explicitly linked to the Sorcerer's Stone. If he can get Harry to obtain it for him, he's won.

The parent was the first hypothesis that I formed when I first read that chapter, but it doesn't check out. Putting yourself out of action for ten years and waiting another ~7 for your chosen champion to mature doesn't look like an optimal way of taking over the world.

And then there's the whole Philosopher's Stone plot. Clearly, he's planning to return to power.

Come to think of it, why is the Philosopher's Stone in Hogwarts this year? Dumbledore introduces the Third Floor Corridor in chapter 12, so we know it hadn't been around before.....

It should be possible to test whether or not the mental gymnastics are even possible by getting rationalists to make homeopathy work by believing in it. Then again, it might be harder to expect that a cloaked monster that eats happiness will play poker than to believe that pills packaged just like normal pills will cause symptom relief when you're sick. So you might need to get someone who didn't know about dementors and tell them that they play poker. Be sure to tell it with a straight face. In a textbook might work best.

As Locke says, the question is how much they're capable of doing just because you expect it. Can they break the laws of physics? That sounds like an awesome thing to test.

And as long as we're trying to find magical exploits, I wonder what Harry would do if he got his hands on some Felix Felicis.

For instance, if he locked himself in a room with only a weegie board (or scrabble tiles), would it be forced to spell out whatever information he needed to know? Would it only answer his direct questions, or could it just start warning him about all of Quirrell and Dumbledore and Lucius' plans and how to beat them?

Kennard claimed he learned the name "Ouija" from using the board and that it was an ancient Egyptian word meaning "good luck." When Fuld took over production of the boards, he popularized the more widely accepted etymology, that the name came from a combination of the French and German words for "yes".

I got the impression that Felix Felicis had extraordinary or possibly perfect knowledge of the current state of the world and the drinker's utility function, was thus able to calculate the best course of action over the period of time the drinker would be under its influence for, and hijacked the drinker's System 1 (and possibly motor control) until it was out of xyr system.

If it DOES hijack the user's motor control, which there is SOME evidence for, then it probably would work with a Ouija board (but scrabble tiles come in specific, limited sets-- might not work right), but then what does it mean that Harry didn't use one in canon when his goal was to find out about the horcruxes? If it were that easy, the potion should have made canon Harry use something similar to find the number of horcruxes and their locations, and probably the curses on them, too.

So I think it doesn't do that. And I don't know how much good it could do him in a locked room with a Ouija board if it can't do that. I think the best thing there is to shout "Hey, Hermione, the experiment's a failure! Let me out!"

Indeed; one wonders why Harry didn't accidentally break a horcrux that day, or why there weren't more enemy casualties in the Battle of the Astronomy Tower.

Harry accidentally breaking a horcrux would have been so phenomenally difficult... AND, the FF had to time everything right to happen to meet Slughorn AND happen to brush against Ginny at just the right time, and then he spent the whole time after that at Hagrid's. The nearest horcrux was in the Room of Requirement; the nearest horcrux-destroyer was in Dumbledore's office. And which is more valuable, one horcrux or knowing how many there are?

Sirius didn't seem to me to be quite intelligent enough for that. Harry makes a comment about Pettigrew being substantially smarter than Black. Additionally, there was this line:

"You are the clever one," said the voice, and the black mist evaporated away, no longer obscuring; she saw the face beneath, and recognition sent a jolt of terrified adrenaline bursting through her -

Mr. Hat and Cloak is apparently someone Hermione is familiar enough with to recognize at a quick glance.

It's easily possible that Hermione has seen at least one picture of Sirius (she mentions him by name as the Potters' betrayer in Chapter 8), and given her memory it would be plausible for her to recognize him, even months afterward. Additionally, Sirius is one of the few people who would cause an immediate reaction of terror at first sight.

Another one might be - bear with me here - Lucius Malfoy. This idea is a little shakier, as it's less plausible that Hermione is familiar with his appearance, but the advantage is that it neatly accounts for the otherwise-strange

The black mist darkened and lightened, like a shake of the head. "I am frightened of Harry Potter," it whispered. "Of the coldness in his eyes, of the darkness that grows behind them. Harry Potter is a killer, and anyone who is an obstacle to him will die. Even you, Hermione Granger, if you dare truly oppose him, the darkness behind his eyes will reach out and destroy you. This I know."

since Lucius seems to be convinced Harry is possessed by Voldemort. (Though it casts a certain odd light on Mr H&C's warning to Hermione about Lucius, I think it's at least possible that he could bite his tongue enough to say "though you are Muggleborn, you possess a power of wizardry greater than any pureblood" if he considered it just a flattering lie.)

The obvious antipathy toward Dumbledore and knowledge of Snape serve equally well as evidence for Lucius or somehow-evaded-going-to-Azkaban!Sirius. Interestingly, they also work for Pettigrew, who Lupin tells us "adored secrets," but who presents the issue of Hermione almost certainly not recognizing or being terrified of him.

Of course, the only reason to entertain such out-there possibilities is how weirdly clumsy and out-of-character this latest act would be for Quirrel. Mr H&C's first appearance (in Chapter 35) is really obviously Quirrel, if for no other reason than

Chapter 35: Mr. Hat and Cloak gave a whispery chuckle. "Indeed," said the whisper. "With the murder of one student five decades ago being the exception that proves the rule, since Salazar Slytherin would have keyed his monster into the ancient wards at a higher level than the Headmaster himself."

Chapter 49 (Quirrel): "First, I believe the Chamber of Secrets is real, as is Slytherin's Monster. Miss Myrtle's death was not discovered until hours after her demise, even though the wards should have alerted the Headmaster instantly. Therefore her murder was performed either by Headmaster Dippet, which is unlikely, or by some entity which Salazar Slytherin keyed into his wards at a higher level than the Headmaster himself."

Well, what do we actually know about the sequence of events? Assuming that things are presented in chronological order seems a bit premature, especially in this fic. More specifically, of the Aftermaths last chapter we know that

  • Dumbledore+Harry began at 6pm (with an addendum at 9),

  • Quirrel+Snape was precisely at sunset,

  • Draco+Bulstrode was at some unknown time in the afternoon or evening,

  • Draco+Goyle was some unknown time after that, and

  • Hermione+Mr H&C was also unknown, but either before or after Draco+Bulstrode (since Millicent was present at the meeting Hermione was coming from.)

As far as I know, we are given no indication at all when Interlude with the Confessor happens. It could be immediately after Snape gets back from the meeting with Quirrel, it could be immediately after Hermione is mindraped, it could be the next day for all we know.

But even assuming the Aftermaths are in chronological order, and the Interlude does immediately follow on to the last Aftermath... Snape could have been, say, checking on the third-floor corridor to make sure Quirrel wasn't bluffing about having stolen and replaced the Stone. In fact, I would expect him to have done this anyway, whether or not he then put on a Hat and Cloak and serial-Obliviated a twelve year old girl. (Eugh.)

That's all true. And on re-reading, I'm going to go back to my original thought of Quirrel, with the emotional involvement being faked to keep Hermione's interest. Quirrel did, after all, speak up for her when all others were silent.

There's certainly evidence pointing that way: "the sibilant whisper" - "dry as dust" - "the high-pitched chuckle" , "What's your name?" "That is the riddle, young Ravenclaw" , and indeed "for now you have seen how the others stayed silent"...

But while I could easily believe that Jeremy Jaffe is better at projecting false emotion than Hermione is at discerning it, I have a much harder time believing that He-Who-Must-Not-Be-Named, whose eyes blazed crimson like miniature suns, could forget the value of surface appearances.

I've already posted this in the reviews as well as on TvTropes, but I figure it can't hurt to share it here as well. (As well as pose it somewhat more formally.)

Harry's freak-out in the beginning over the animagus transformation got me thinking. Between the two possiblities: a) the laws of physics Harry believes are wrong and b) the animagus transformation only appears to violate Conservation but doesn't actually do so, it seems fallacious to skip to possibility-a without ruling out possibility-b.

After some thought, I was able to generate a hypothesis for how Variable-Mass Shapeshifting Between Multiple Fixed 3-Dimensional Structures might work without violating Conservation; I don't know enough about physics to guess if it is plausible--One of the clues I'm basing this guess on was that Harry did not in any way remark upon the existence of containers that are bigger on the inside than on the outside, and the inference that magic can create space and that this does not violate any law of physics that Harry knows of.

The two or more 3-dimensional forms with differing mass all exist simultaneously in an unchanging 4-dimensional superstructure. The form that is perceivable in our 3-dimensional universe is whatever cross-section of the superstructure happens to intersect our 3-dimensional grid, and "changing form" involves only unidirectional motion along the inferred extrauniversal axis.

VMSFF = Variable-Mass Shapeshifter with Fixed Forms

Possible Evidence for:

  • VMSFFs rarely have more than one alternate form. (Magic has to create space for each alternate form on the 4th spacial dimension. No indication that additional space does not require additional energy to maintain.)
  • VMSFFs transform quickly. (Same reasoning as above: there is as little intermediate matter as possible.)
  • VMSFFs demonstrate similar cognition regardless of form. (Suggests both brains are present and active at all times.)

Possible Evidence against:

  • Dementor effect is less in animal form. (Suggests that either both brains are not equally present, or that Dementor Effect is constrained to 3-dimensional space.)
  • Animal urges change with the form. (Suggests that both brains are not equally active. Weak evidence, as bleed-over of urges between forms is observed.)
  • Injuries in one form translate to the other(s). (Suggest the two forms are not separate parts of a larger entity.)

Tests:

  • How is an animagus form destroyed? (Is it closer to Amputation or Obliviation?)
  • Does wearing heavy clothes vs. nudity affect the amount of energy necessary to transform? (Does the difference in energy match the inertia of the clothes?)
  • What does the change feel like to the animagus? (Is it sensationless as switching from one set of sensory imputs to another would suggest, or is it sensable as having sensory imputs within changing matter would suggest?)
  • In the case of the Wolves in Luminosity, is the mass of consumed food greater than the mass of the Wolf's human body plus waste? (If so, does the cumulative difference match the mass of the Wolf upon first Floof? For animagi, does the magical energy expended to create the alternate form in the first place match that needed for the transfigured-creation of a similar mass?)
  • Is being an animagus a permanent drain on one's power?

In any case, I've been thinking about it for a while and a 4-dimensional superstructure is the only way I can imagine it working. Alternate Hypotheses anyone?

It could easily be a very small drain. Harry goes around with that transfigured rock on his finger which is implied to be a not-insignificant constant drain on his magic, yet does not seem to be a noticable detriment to his spellcasting.

Another Test: A persons magic is often likened to a muscle; it gets stronger with use. If the "muscle" could be measured directly would its average strength be higher among Animagi? (Actually testing that would be impossible; there simply aren't enough animagi in the world to get meaningful statistics, but if there were...)

Edit for "Duh" moment. If destroying someone's animagus form is non-invasive, does the former animagus suddenly have slightly more magical power than before their form's destruction?

A hypothesis I'm currently toying with: Quirrell and HJPEV are different versions of the same individual, in some sense, and the Quirrell version is using some form of magic (probably involving breaking the 6-hour-limit on sending information backwards through time, possibly involving possession of a real Quirrell) to carry out a process of recursive self-improvement on himself. The story we're currently reading takes place in one iteration of the loop.

Has anyone posted this idea before on the net?

There are some serious problems with this hypothesis:

  • Quirrell and HJPEV appear to have very different utility functions.
  • Performing recursive self-improvement starting with a human hardly seems like the kind of thing Eliezer would advocate, considering the likelihood of ending up with an unfriendly superintelligence.

So it's probably wrong, but I thought it was interesting enough to post.

Quirrell seems to be trying to fix that too; sounds like a feature, not a bug.

There have been numerous time travel / "Quirrell is Harry" theories before. Given the relationship between MoR and other fanfic, I'd be surprised if there was never a Peggy Sue or other non-time-turner time travel. Insane Weasley brothers notwithstanding.

The story we're currently reading takes place in one iteration of the loop.

I don't think this fits the style. Much in the same vein as Stross's "Palimpsest" (and Bill & Ted's Excellent Adventure for that matter), the reader/viewer always sees only the final iteration, because that's what the subjective experience would be to someone experiencing this. So if this is the case, we're reading the last iteration (see both the initial time-turner prank and the attempted use of the time-turner to factor in polynomial time).

That being said, it's my pet theory that Harry goes dark and does something horrible in the future, and sends himself way back to try to stop all that, and we're reading the final iteration of that. And that future Harry is Mr Hat-and-Cloak. But that's just me, and this isn't well supported.

Sorry if this has been asked before, my meagre google-fu skills fail to reveal it.

Chapter 55. When Harry cast his Patronus in Azkaban, he lost some of his "life" to sustain it:

Slowly the light died back down.

Part of Harry's life flowed back into him.

Part had been lost as radiation.

[...]

So Harry walked on, leaving a piece of himself behind. It would dwell in this place and time forever, he knew. Even after Harry came back someday with a company of other True Patronus casters and they destroyed all the Dementors here. Even if he melted the triangular building and burned the island low enough that the sea would wash over it, leaving no trace that such a place as this had ever once existed. Even then he wouldn't get it back.

If you taboo "life", what exactly did Harry lose there and why should he never be able to regain it? It seems unlikely that MoR of all things subscribes to the idea of living things having a life force in some vitalist or spiritualist sense...

Also, will this have any effect on anything in the story? Did Harry permanently weaken his own magical potential or something of that sort?

I also view this as poetic language, not a literal loss of some substance, but a major change in the person that is called Harry. If enough change makes you a different person, than any major change can be seen as the fractional death of the previous person you were. Value drift is a pretty common subject around here.

Harry has just been inside an active concentration camp for hours. I hear that many allied soldiers were massively altered when they first came upon & liberated the Nazi concentration camps. It's even possible that something similar to this was written by returning soldiers in memoirs. I think poetic language is to be expected when processing this sort of trauma.

I'm pretty sure something more literal was meant. The way the story is written, it sounded like Harry was in danger of dying from exhaustion, expending... something, to fuel his Patronus. And expending irrecoverably, it is stressed, so it's not like he just did the equivalent of a life-or-death sprint which made him really tired.

I see no indication that the thing permanently sacrificed was the same thing fueling the Patronus. I think the Patronus burns "life" in the sense of one of the things Dementors also suck out, but that can be regenerated by resting (it was implied that the prisoners in Askaban would partially recover magic and something else if the Dementors didn't keep sucking it out when the true Patronus gave Bella a weeks worth of such regeneration back), and it seems unlikely that such a loss to Patronus radiation would be more permanent than loss to Dementors.

Hmmm, I see what you mean. "For it wasn't his magic he had expended, it had never been his magic that fueled the Patronus Charm."

I don't think that using the Patronus 2.0 permanently sacrifices anything though. After all, he's perfectly fine after killing the Dementor at Hogwarts, a situation in which none of his "life flowed back into him."

Are you sure? I read it as referring back to that scene specifically. The exact quote:

Harry felt... well, normal again. Sane-ish. The spell hadn't undone the day and its damage, hadn't made the injuries as if they had never been, but his hurts had been... bandaged, meliorated? It was hard to describe.

Dumbledore was also looking healthier, though not fully restored. The old wizard's head turned for a moment, locked eyes with Professor Quirrell, then looked back to Harry. "Harry," Dumbledore said, "are you about to collapse in exhaustion and possibly die?"

"No, strangely enough," Harry said. "That took something out of me, but a lot less than I thought it would." Or maybe it gave something back, as well as taking... "Honestly, I expected my body to be hitting the ground with a thud about now."

(Bold emphasis mine.)

J.K. Rowling is releasing some character bios on Pottermore, and showing a flagrant disregard for MoR!canon. In particular, McGonagall's father was a Muggle Presbyterian minister. Even though, in MoR:

Minerva stared at Severus, feeling sick to her stomach. She had studied Muggle religion - it was the most common reason for needing to Memory-Charm the parents of Muggleborns - and she knew enough to understand what Severus had just said.

Furthermore, per the bio McGonagall was ten years old and still living in the Muggle world when atomic bombs were dropped, so she'd probably know about nuclear war.

Obviously this sort of collision is inevitable, and since it's a full-blown AU there's no obligation to fix it. In this case, though, it might be possible to enhance the text with some minor retcons. In chapter 61, maybe when Severus mentions prayer, Minerva remembers her childhood and thinks "they had offered prayers, every dinner and every Sunday at church, for the brave soldiers at the front. It had seemed impossible to her, at that age, for any remotely humanlike being to even consider not answering them."

Then later in the same chapter, when Dumbledore alludes to nukes:

"What?" said Minerva. She had heard of guns, of course, but they weren't that dangerous to an experienced witch -

Maybe then Minerva thinks back, and remembers that nobody would explain to her exactly why Japan surrendered, as though what had happened was something even more terrible than a war...

It seems to me that Minerva serves a useful narrative purpose primarily because she is a not-particularly-well-informed pureblood in Dumbledore's inner circle. Making her a half-blood alongside Snape... well, it reduces the opportunities for culture shock rather a lot. Who could be brought in to showcase the viewpoint of Light-sided purebloods, the Weasleys?

Not to mention I feel like Minerva would be a lot less sympathetic as a character if she weren't so consistently off-balance.

That brings up another point. In the Philosopher's Stone, Dumbledore enchants Erised so that only those who want to find the stone, but not use it, would be able to have it. If Dumbledore did in fact hide the stone in Hogwarts, I can't see either Harry or Quirrell not wanting to use the stone.

Is it even possible for Dumbledore to hide anything in such a way that Harry can get at it, but Quirrell cannot? Harry's major ideal difference -- his war against death -- isn't even understood by Dumbledore. Not to mention that such a hiding place would have been constructed before Dumbledore even met Harry.

I think you hit on a key point that several are missing--Dumbledore wouldn't want HJEPV to have the stone any more than Quirrell (well, maybe a little more, but certainly less than nobody having it or even than handing it off to, say, some random Hufflepuff). In canon Harry didn't just not want to use it, he didn't want it used--that was his entire motivation for getting it. Rational Harry would, probably quite literally given enough time to think on the situation, kill to use it, and use it repeatedly. And Dumbledore knows this.

Canon Harry was, in fact, a person Dumbledore would be willing to loan the stone to if necessary. Rational Harry is not. The mirror actually represents a pretty effective screening process for who does and doesn't fall in that category, especially combined with what in theory should have been a screening test to ensure you were a capable enough wizard to protect it and/or had the approval of several people he trusted in a more general capacity. In fact now that I say that, it suddenly seems plausible that the mirror wasn't in any way tied to how it was hidden, and instead was just the trigger used for retrieving it. In which case, actually, a sufficiently powerful wizard with sufficient time could probably deconstruct the spell and take it by force, simply because no lock is perfect, which is why it still needed to be guarded in the first place and why stopping Quirrell was necessary.

The problem is, Dumbledore's not going to tell Harry what the condition is for getting the stone. Why would he? He didn't tell canon Quirrell, who was standing there trying to figure out why he couldn't get it. He didn't even tell canon Harry until after the fact. The mirror as a screening process works even better if the person being screened doesn't know what it's testing for, and thus can't fake it.

And Harry would want to use the stone, make no mistake. The first thing he'd do with it is make himself immortal, to make sure no accident or fluke could stop him from having time to mass produce the immortality elixir. And he'd be using it for study anyways. But the most important part is that even if he is capable of precommitting and one-boxing, and even if that kind of trick fools the mirror, he'd first need to know that that was the condition necessary to obtain the stone. And you can probably count the number of people Dumbledore trusts with that information on one hand.

Given the author, Harry could also be told after getting the stone that he could only get it if he would not use it, and therefore he would not use it. And he's already been cautioned against magical paradoxes.

Ok. Valid point. But after trying at a few minutes Harry might be able to understand Dumbledore enough to realize what the trick is. On the other hand, that might take far more empathy for the viewpoints of others than Harry generally has.

This begs the question, if Harry figure out the secret of the mirror, would he be able to construct an Occlumency proxy personality who didn't want the stone?

That sounds like a reasonably good prediction about the way that plot path would go. It sounds at least partially analogous to one-boxing, and we know the author one-boxes.

Indeed! I've always imagined the only explanation as sheer carelessness; MoR!Harry would have left it.

In the books Harry's success is essential due to the fact that every time Voldemort tries to kill him Harry is magically protected by something unforeseen. Voldemort isn't clever enough to just kill him by non-magical means.

In MoR I imagine that Harry won't have such convenient protections.

I don't think that would be enough. In canon, Quirrel wanted the stone to use on Voldemort, not on himself, and he couldn't get it.The only way to get the stone in canon would be to want to have it to keep someone else from having it. HJPEV would want to use it on other people, therefore he can't get it. Unless he could get an exception for wanting to give it to someone else, who would then be able to use it.

The Weasley twins at one point mention taking the corridor all the way to the magic mirror and back, although they presumably didn't escape detection while doing so. If that's possible, I'd say it's unlikely that a guy like Quirrell would have found it impossible to defeat himself or (if he was concerned about detection) to leverage some student adventurer into defeating.

The safe bet seems to be that it's a red herring.

One thing that I found interesting but that I haven't noticed anyone else mention.

In chapter 76, we have:

But, as Hermione had explained to Millicent, prophesying wasn't controllable, there was no way to ask for a prophecy about anything in particular. Instead (the books had said) there was a sort of pressure that built up in Time, when some huge event was trying to happen, or stop itself from happening. And seers were like weak points that let out the pressure, when the right listener was nearby. So prophecies were only about big, important things, because only that generated enough pressure; and you almost never got more than one seer saying the same thing, because afterward the pressure was gone. And, as Hermione had further explained to Millicent, the seers themselves didn't remember their prophecies, because the message wasn't for them. And the messages would come out in riddles, and only someone who heard the prophecy in the seer's original voice would hear all the meaning that was in the riddle. There was no possible way that Millicent could just give out a prophecy any time she wanted, about school bullies, and then remember it, and if she had it would've come out as 'the skeleton is the key' and not 'Susan Bones has to be there'.

But in chapter 63, we have:

Final Aftermath:

She came awake with a gasp of horror, a disruption of her breathing that left her feeling deprived of air and yet her lungs didn't move, she woke up with an unvoiced scream on her lips and no words, no words came forth, for she could not understand what she had seen, she could not understand what she had seen, it was too large for her to encompass and still taking shape, she could not put words to that formless shape and so she could not discharge it, could not discharge it and become innocent and unknowing once more.

"What time is it?" she whispered.

Her golden jeweled alarm clock, the beautiful and magical and expensive alarm clock that the Headmaster had given her as a gift upon her employment at Hogwarts, whispered back, "Around two in the morning. Go back to sleep."

Her sheets were soaked in sweat, her nightclothes soaked in sweat, she took her wand from beside the pillow and cleaned herself up before she tried to go back to sleep, she tried to go back to sleep and eventually succeeded.

Sybill Trelawney went back to sleep.

This aftermath was widely considered to have been Trelawney giving a prophesy. However, as we just found out (assuming that the information Harry and Hermione gathered is accurate) that prophesies aren't given, the pressure doesn't get released, unless the right person is nearby. However, Trelawney appeared to be alone in that aftermath. This opens a number of different options.

  • The information from the books is wrong.
  • Trelawney was not as alone as she appeared.
  • The speculated recording spells count as being the right nearby listener. Interestingly, this could mean that Dumbledore isn't the right listener, if others also have recording or listening spells around Trelawney.
  • Trelawney wasn't actually giving a prophesy. The first time I read it, I thought that she "couldn't discharge it," and then it did discharge but didn't realize, because she could never remember her prophesies. But with this new information, that suggests to me that perhaps all of the pressure was building and building, but it was unable to vent itself at that time because the right person wasn't there. If this prophesy is similar to the one in canon, then that means it won't express itself until she's near Harry Potter.

Does anyone else see anything that I missed?

During Hermione's description, my brain immediately pointed out that no one could possibly know whether or not Seers can give prophesies with no one around to hear them, because the Seers don't remember doing it and, well, there's no one else around to notice.

Maybe Seers are just constantly prophesying when they're alone and no one has any idea.

I don't think that would really settle the matter, though. All you would then know is whether seers prophesied when only in the presence of recording devices. (If a seer prophesied in the forest and no one was there to hear, would it constrain the future?) I wonder what you would call that, actually- the Cassandra Uncertainty Principle?

Confirmation Bias exists for wizards just as well as muggles.

Nobody remembers the three other children destined to defeat He-Who-Must-Not-Be-Named, and that's to be expected for someone who dies so young with no notable achievements to their name. But Harry Potter? Why, once the Dark Lord is defeated and the story gets out, everyone will know he was prophesied to win for sure!

  • The information from the books is wrong.

The official explanation for prophecy was presented alongside a character who exploits other people's belief in destiny in order to mislead them. It appeared in a chapter called "Surface Appearances". It might not be safe to take it at face value.

I think there were already (extratextual) reasons to doubt that Eliezer would implement prophecy that way, but there's another one.

(This sort of goes along with all the other responses to the grandparent, but Donny's is the best fit):

I'm having a hard time believing that the girl who said this-

Instead (the books had said) there was a sort of pressure that built up in Time, when some huge event was trying to happen, or stop itself from happening. And seers were like weak points that let out the pressure, when the right listener was nearby. So prophecies were only about big, important things, because only that generated enough pressure; and you almost never got more than one seer saying the same thing, because afterward the pressure was gone.

Is the same girl who said this-

Hermione turned back to face Dumbledore again, took a deep breath, and said, "Well, maybe people who are going to be heroes, will be heroes no matter what. But I don't see how anyone could really know that, aside from just saying it afterward. And when I told you that I wanted to be a hero, you weren't very encouraging."

Okay, say that prophecies are caused by 'pressure in Time' from great events that are 'trying' to happen. How could anyone know that? What's worse, though, is that she did this research with Harry, who apparently let her walk away believing this nonsense.

Edit: (And if Eliezer pops in to say the Department of Mysteries has a room full of Temporal Barometers I will be very unhappy.)

Even if the explanation given for the observations is wrong, it wouldn't change the observations, that prophesies only ever seem to be about big important things, don't occur on demand, and don't get delivered by multiple seers or by the same seer more than once. Whether Hermione believes the explanation or not (she'd certainly be wise to be skeptical of it) doesn't affect whether she has enough information to dispense with the hypothesis that Millicent is a seer.

The fact that she related the contents of some books to Daphne and Millicent doesn't necessarily mean she bought their contents wholecloth, it could have just been the simplest way to make a point. She might have believed it; remember that Hermione much more than Harry is used to taking things she reads at face value, and compartmentalization is normal, but I wouldn't take it as established.

I am able to distinguish between observations and inferences, and I certainly never argued that Millicent (or, rather, her sister/Miss Felthorne) was actually a seer. The problem was that Hermione seemed not to distinguish between them, even in a mental aside. Heck, even Draco only took one conversation with Harry before he figured out the difference between demonstrable facts and non-demonstrable explanations for those facts.

Of course, the more I think about it the less unlikely it seems. The whole 'pressure in Time' business rather offended my sensibilities at first, but... well, they certainly don't treat fragile Time-Turners as though they were irreplaceable artifacts of lost Atlantis, which rather implies they can make more, which rather implies (though certainly does not prove, given the example of Transfiguration) that they have some idea what they're talking about when it comes to the theory.

I think it also sort of implies that Eliezer has a coherent metaphysics going on behind the scenes. The decision theoretic generalization of anthropic selection, reifcation of good story selection effects like conservation of detail or whatchamacallit from tvtropes, things like that. I heard that he once wrote a story about time machines? Or at least one about "outcome pumps". I wouldn't be surprised if he reuses his cleverest ideas from there in HP:MoR.

One question about theology, miracles, and Newcomblike problems that intrigues me:

If I was in a Harry Potter fanfic I would probably find out within 3 hours and then spend the next two weeks reading about common plot twists of Harry Potter fanfiction, knowing that my breaking the fourth wall so explicitly was either happening behind the scenes or I was in the fanfic of a very meta-cognizant author.

But what if that's a bad idea? The author has a model of me in his head, and if he knows that I'm the type of person who does that then he might change the story to make my metaness futile (because the only reason you'd write a story like that is to include irony of some kind), or less saliently he might just decide not to write the story in the first place. So should I not allow myself to think certain thoughts about what characteristics the author of the farce is likely to have, because doing that is like asking to be made the subject of an ironic twist?

Unfortunately IRL I'm in a Will_Newsome story where the hidden rules are significantly harder to think about.

In fanfic for almost any universe (whether Harry Potter, Star Trek or whatever) fanfiction devoted to that universe doesn't exist for obvious reasons. So this seems unlikely. Moreover, even if one had almost any fanfic that did have the fictional version of the universe inside that universe also (almost all of which is deliberately silly things like Barry Trotter) there's not much way for you to rule out being a character in the fanfiction- you are random Muggle number 10543549 and you will never encounter any wizards in your life, or if you do, will not realize it.

for decision theoretic reasons I never expect to find myself as a muggle in any story.

What do you mean? I can understand the argument that random muggles aren't likely to be simulated to full fidelity and so entities that have enough processing power to act as observers shouldn't expect themselves to be random bystanders in a story about people they never meet.

I'm not sure someone in a good story would recognize that they are in a story even when it is highly optimized. From the reader's perspective Harry might be interesting but even from his perspective he's spent days in classes, he's spent hours listening to Professor Binns drone on, he's had to do tedious homework, and he's had 11 years where he was just like a lot of other very smart kids, many of whom beat him in math contests.

Three last names is not that uncommon, and there are a lot of abnormally intelligent people in the world. Of the people who are in the top tenth of a percent in intelligence there have to be around six million people on the planet who fit that. So the chance that anything special is happening is still really low at that point. The chance might get higher overtime. And it helps that Harry is genre aware enough to sarcastically ask if there's a prophecy about him. (That section is still by far one of my favorite parts of the story.) So he's already located the hypothesis to some extent although he may have located it due more to pattern matching than actual evidence. Moreover, at the same time, Harry knows from talking to Dumbledore and reading old books about Gryffindor and others that in their universe there is such a thing as heroes. So Harry doesn't have a strong reason to see why his heroism isn't different than Gryffindor's. He might be the character with well meaning intentions who goes evil so that someone can arise to stop him in a few years. He'll be the classic MagiTech using villain, and it might even have a big anti-transhumanist undercurrent.

It seems that you might be engaging in a weird form of hindsight bias together with possibly the illusion of transparency.

I don't follow. Or, it seemed like you were listing reasons why he should suspect he's in a story, but then you seemed to think I was committing hindsight bias for thinking so. Is it because "3 hours" is an exaggeratedly short time to make the inference? 'Cuz "I'm the main character" had secretly been Harry's hypothesis since forever, as was revealed under the Sorting Hat.

Sorry if that wasn't clear.

The first part is a response to your observation about abnormal intelligent. My point was that there are around six million people of Harry's intelligence level, so being that intelligent is not a good reason to think one is a protagonist.

I then agreed that Harry's aware of the genre in question which might help slightly.

My point about Gryffindor and the like was that even if Harry thinks he's in a story he doesn't have good reason to necessarily assume he's the protagonist. In fact, look at the confusion from other genre aware characters about what genre they are in. So Harry could be a well simulated villain for later use.

Harry under the sorting Hat thinks he's important. That's not the same thing as thinking one is a protagonist in a story. Being willing to believe that one is the prophesied hero upon everything will fall is something lots of little kids want to believe. A lot of them convince themselves that they are somehow important or unique. (A weird example are Emo and Goth kids who convince themselves that they somehow have terrible suffering which no one else understands. Similarly, this is why X-Men is such a popular comic.)

The hindsight bias is that you know that Harry really is the main character. So in that context it is easy for you to look at all the evidence and say "yeah! See. It is obvious."

Harry is like Eliezer, I am like Eliezer, I am like Harry, and I've always guiltily thought I was the main character, and I'm pretty sure that Eliezer and Harry have too. (Luckily there are many stories going on.) Combined with all the explicit cues about wanting to become God and thinking he's incredibly important and then being sorta vindicated by the prophecy...

"Being the Messiah is like being Athlete of the Year."

I'm not sure what specifically you mean by "this premise". Would the Dark Tower series by Stephen King count? That's the first work of literature that I'm aware of that had a sort of anti-Death of the Author (Resurrection of the Author?) as an actual plot point.

(For extra meta, the guy who came up with the term 'death of the author' was Roland Barthes.)

It might have a credible meaning, depending on how we explain the facts of time travel. Perhaps some agent inspires prophecies to help ensure a coherent timeline.

This suggests that HJPEV or Voldemort will, as a result of the prophecies, affect the distant past somehow and become their own metaphorical grandfather (e.g by 'erasing Atlantis'). But it doesn't have to mean that. Perhaps without post-prophecy Harry, Voldemort would simply have gotten bored with world domination and decided to kill his own grandfather again.

There may be theoretical considerations that suggest that prophecy works this way. There may be some framework where this is the simplest interpretation, sort of how many-worlds is arguably the simplest interpretation of quantum mechanics even though we can't observe other branches of the wave.

Back in chapter 21 Trelawney started giving a prophecy in the middle of lunch and Dumbledore used the phoenix to teleport her away. If the books are correct this probably made the prophecy useless as anyone in the room could have been the intended recipient, but the true meaning would probably be lost among that large an audience anyway.

As a side note if the he-who-is-coming in the prophecy is Mr. hat-and-cloak then that would rule out Snape and Quirrell. Though I don't think manipulating first year army battles and messing with Granger's head would count as "tearing apart" anything worth prophesying about.

I think it's pretty clear she didn't give it:

she could not put words to that formless shape and so she could not discharge it, could not discharge it and become innocent and unknowing once more.

So, the question is whether Trelawney has been carrying a headache since chapter 63 and has been within earshot of Harry. Doing a quick search on her name, 'prophecy', and one or two other terms, as far as I can tell there has been zero mention of Trelawney since.

There's a simpler explanation that I hadn't thought of before: Dealing with adults isn't a course of action that occurs to Harry. (Remember the "why didn't I think of that" when he thought of telling McGonagall about the Sorting Hat charm?)

In other words, it's very in-character for Harry. Yay to Eliezer for consistent character development.

Now, the real WMG: Voldemort was this way as well. (Notice that in the King's Cross discussion, it's Harry saying "I prefer to deal with the part of House Malfoy that's my age" that really freaks Lucius out.)

I thought the reason that that statement freaked him out is because Lucious was talking to harry as if he was possessed by Voldemort in an attempt to see if that was the case, and he interpreted the remark about age as a confirmation. It makes sense if you look at the statement as a deception because Ms. Longbottom walked up. I'm paraphrasing the first part:

I wont tell Ms. Longbottom to leave because "I prefer to deal with the part of House Malfoy that's my age" =>

I would like to tell Ms. Longbottom to leave because I prefer to deal with the part of House Malfoy that's my age(but I wont because I want to keep up appearances).

That reading seems far-fetched.

Let's go over the conversation....

Part I: Lucius accosts Harry and speaks to him as if he were Voldemort. Harry pretends to be Voldemort (without meaning to). Lucius maintains his calm.

Part II: Harry goes "you think I could benefit from doing Draco harm. But it is irrelevant, Lucius. He is my friend, and I do not betray my friends." Lucius goes 'what the fucking FUCK?'

Part III: Longbottom arrives, Lucius asks Harry to send her away, Harry spouts the "my age" comment, and Lucius goes, "I do feel the fool now. This whole time you were just pretending to have no idea what we were talking about."

Judging by part 3, Lucius wasn't fooled by Harry's act in part 1, but kept playing along just to make sure. Harry says enough incriminating stuff in part 1, but that doesn't convince Lucius... Clearly, he realises that that's what anyone trying to gain information would say. Since he's convinced in part 3, though, he must have had a relatively low prior on anyone except Voldemort saying what Harry did... But why? Why? What's so special about that one off-hand comment?

<retracted, see Locke's reply> Then again, if he wasn't convinced in part 1... Why was he shocked in part 2? I can imagine him being shocked at Voldemort saying something like that, but why would he be shocked at Harry Potter saying it?

.... Something's not right about this whole thing.

I still think he takes it as a confirmation that Voldemort is possessing Harry. Voldemort is much closer in age to Lucius then Draco. Voldemort playing strange games with your son is much more concerning then the boy who lived playing strange games with your son. Also consider Lucius's parting statement: "And as you have asked nothing more of me, I will ask nothing more of you."

Why would the boy who lived ask anything of Lucius? Voldemort certainly would.

"Oh, the little fiddly things?" said Dumbledore. "They came with the Headmaster's office and I have absolutely no idea what most of them do. Although this dial with the eight hands counts the number of, let's call them sneezes, by left-handed witches within the borders of France, you would not believe how much work it took to nail that down."

Chapter 17.

I know it's supposed to be a joke, but.... How? Is Dumbledore monitoring every wizard and witch's sex life? And how did he manage to crunch that data? Do wizards have calculating machines?

Or maybe he meant to say "the documentation took a lot of work to find and decipher"?

Eh, it was probably a given from the start that it was counting something.

Then immediately after the French Ministry of Magic authorizes/legalizes a new "Give yourself multiple orgasms" charm, or even just a new magical Viagra, the device's count jumps up. At that point Dumbledore knows it's counting something that correlates strongly with sexual satisfaction, but the count is a bit too low to be counting the orgasms of the entire French female magical population. Turns out the inventor was a jealous French wizard who tried to keep tabs on his left-handed wife, but keyed in the criteria too weakly, so that any left-handed witch within the borders of France would do.

I find it more likely that he tinkered with the object itself, if that's even true.

I wonder if Quirrell could have managed to get a fiddly thing of his own invention into the headmaster's office before Dumbledore took over for Dipot. Perhaps as a gift to the old headmaster. It'd be an incredibly useful source of knowledge, if Wizards do in fact have magical listening devices.

It seemed like Dumbledore was going out of his way to screw with Harry in this chapter. Even if the machine actually does what he said it does, I could easily see the comment about "how much work it took to nail that down" being a joke Dumbledore told for his own amusement, knowing that Harry was too young to "get it".

There are certainly some analytical charms that give you some sort of idea how magical objects work. For example where Harry offers Dumbledore and Quirrel some Comed Tea, they both analyze it before drinking.

The complexity of such analytics probably scales withe complexity of the magical object that is being analyzed, so finding out about the dial was probably immensely difficult, but not by collecting and correlating data, but by inspecting the device rather closely.

Not that I disagree, precisely, but I'm not sure you can use the Comed-Tea thing as evidence that it's possible to analyze how magical objects work: Quirrell and Dumbledore both seemed taken by surprise by the actual effect, after all. The charm(s) they used seem more likely to be poison/biologically-interactive-potion detectors.

Or maybe they both decided to fake being caught off guard. That seems like Dumbledore's style, anyway.

Actually, I just had a chilling realization in regards to that. From chapter 62:

'"No," said the old wizard's voice. "I do not think so. The Death Eaters learned, toward the end of the war, not to attack the Order's families. And if Voldemort is now acting without his former companions, he still knows that it is I who make the decisions for now, and he knows that I would give him nothing for any threat to your family. I have taught him that I do not give in to blackmail, and so he will not try."

Harry turned back then, and saw a coldness on the old wizard's face to match the shift in his voice, Dumbledore's blue eyes grown hard as steel behind the glasses, it didn't match the person but it matched the formal black robes.'

I strongly suspect that Dumbledore burned Narcissa Malfoy so that the death eaters would stop targeting the families of Order members. Judging by his tone of voice and body language in this excerpt, this is probably the one action during the war that Dumbledore most regrets having had to do.

If I'm right, Harry will be in a difficult moral situation when he learns the truth. Was what Dumbledore did justified? On the one hand, torturing a mostly innocent person to death is deplorable no matter how you slice it. On the other, if that was the only way to stop many other innocents from being tortured to death...

Another thought which occurred, is that Amelia Bones killed Narcissa in revenge for the Death Eater's killing of her family members, then Dumbledore claimed responsibility in order to send a message to the Death Eater's and Malfoy to discourage further attacks on the Order's families, and prevent Lucius from finding any evidence of Amelia's responsibility, which might have allowed him to remove one of Dumbledore's more powerful allies. He probably would have had to have been careful to give the impression that he would be willing to do so 'again' to the other Death Eaters if he wanted them to stop, though, unless Lucius cares a lot more about his allies than shown so far, or at least made some threat against Draco, who Lucius seems to care about.

EDIT: I was wondering how killing Lucius' wife would provide leverage over the other Death Eaters when I realised something rather obvious in retrospect, Dumbledore is the Headmaster of Hogwarts. He already has plenty of leverage, doesn't he? If need be he can hold all the school age children of Death Eaters and their allies hostage, or expell them, denying them good education and potentially giving them a bad reputation. If the parents withdrew the children and sent them abroad though, they could grow up without the knowledge of local politics provided by a hogwarts education (including personal knowledge of everyone important in your age group, which in such a small society, not-having would likely be a big disadvantage.)

Really, that's what people are objecting to? For goodness' sake, I'm not a deontologist or anything, I'm just referring to what was described as "condition three":

"Condition three is that Narcissa has to have been burned alive. If that part of the story turns out to be something exaggerated just to make it sound a little worse, then I get to decide for myself whether or not to still go through with the pledge. Good people sometimes have to kill. But they don't ever torture people to death. It's because Narcissa was burned alive that I know whoever did that was evil."

It wouldn't be a difficult moral situation on Harry's part because he specifically thought of this exact circumstance in advance.

I can't remember whether it was Dumbledore specifically who was named in that pledge, making it invalid if someone else did it (technically, at least, Draco would probably consider it a betrayal if Harry found out who did it but didn't help him get revenge) but if Amelia did it, then Hermione could be dragged into the situation as well, as a friend of Susan's, and we could have a fascinating obligation tug-of-war for Harry.

"Condition two is that I'm pledging to take as an enemy whoever actually did kill Narcissa, as determined to the honest best of my ability as a rationalist. Whether that's Dumbledore, or someone else. ...

... Condition five is that if whoever killed Narcissa was tricked somehow into doing it, then my enemy is whoever tricked them, not the person who was tricked."

And yes, I think it would be somewhat difficult on Harry's part to explain himself to the people who care about the person who did it; but in this case, Hermione of all people would probably understand why Harry took as his enemy someone who - again - burned an innocent woman to death. I don't think that's the kind of thing Hermione would be willing to let slide just because the person is a friend's aunt.

This may indicate that Harry has not through the relevant issues enough to appreciate this sort of moral dilemma.

The timing seems to line up - the period of seventeen months between Draco's birth and the Dark Lord's defeat works well as "toward the end of the war," and Draco never speaks of his mother as though he had any direct memory of her - except...

The problem is that Draco's description of the sequence of events doesn't seem to leave room for the Dark Lord still being corporeal at the time.

And Father couldn't testify under Veritaserum because he was an Occlumens, he couldn't even get Dumbledore put on trial, Father's own allies didn't believe him after Dumbledore just denied everything in public, but we know, the Death Eaters know, Father wouldn't have any reason to lie about that, Father would want us to take revenge on the right person ...

That doesn't really sound like it happened in a state of open war, does it?

So if it happened shortly after the end of the war, it probably isn't what Dumbledore is referring to there.

No. But it doesn't have to. If we stipulate instead that Dumbledore was untouchable during the actual war for practical reasons (say, being one of the most powerful wizards alive and the de-facto commander of an opposing force, hence well protected), Lucius is left with excellent reasons to go after him through legal channels after the war's over. Neither side seems to have been operating with the full blessing of the legal government, and terror tactics resulting in the deaths of innocents are exactly the kind of thing that a Ministry-run truth and reconciliation commission should be interested in.

It probably wouldn't have started out that way, but your wife's murder isn't the kind of thing you just forget after a ceasefire gets signed. Given Draco's age, the later, legal stages of the feud would be what he'd remember, and thus what he'd convey to Harry.

To me, it's more like... if this happened while Voldemort was hanging around, why would anyone, even the Death Eaters, have to take Lucius' word for anything? Sure, he can't take Veritaserum cause he's an Occlumens, but even if the Dark Mark can't compel truthfulness there's still the issue of uber-magic forensic techniques.

And it's important to note that it's not "a ceasefire gets signed", but rather 'Lucius barely squeaks out of a life sentence through copious bribery'. It seems like one way or another Lucius had to wait quite some time after war's end to level these wild charges at Dumbledore, as doing so from the defendant's stand would seem a rather pathetic attempt at misdirection. In other words, I highly doubt that "a Ministry-run truth and reconciliation commission" was involved at any stage of the process.

The theory I've been going with for a long time is that Dumbledore killed Narcissa accidentally while disposing of Tom Riddle's diary - he thought the house was empty and used Fiendfyre - and then later rationalized her death for the reasons you gave above.

Interesting theory. Though one wonders why Dumbledore didn't just grab the diary and bring it to a safe location before destroying it.

Maybe there was some kind of alarm that would have instantly summoned Lucius if it was taken out of the house? Then again, if you had an alarm system, you'd think someone casting the most destructive spell known to the modern world inside your house would also trip it...

It occurs to me that a Pensieve would be a powerful tool for dealing with any of the Newcomblike problems that have come up so far or are likely to come up in the future -- getting past the magic mirror, for example. Just extract any memories relating to debiasing that you might have, put them in a jar labeled do not open until Christmas, and go talk to whatever the Omega of the moment is.

Might not work like that in practice -- I wouldn't expect it to IRL, at least, since scrubbing a memory probably wouldn't get rid of the weightings that have grown around the concepts it links to. But there's enough story potential that I can see a case for handwaving that away. Starting with the potential value stability problems...

To be honest, looking back at that from three months on I'm not sure exactly what I was thinking. I do still think there's a lot of interest and story potential in a magical item that allows you to edit your own mind to some extent: if pulling out memories also removes your associations with them, you don't just have external storage, you have something very close to a general personality editor.

I'd actually be a little surprised if it doesn't come up down the road -- but the specific application that 20110929!Gest suggested up there looks far-fetched to me now. You'd have to have a very good idea of what's linked to what in your head, and you'd probably have to make some pretty extensive changes to change your answer to a Newcomblike problem. Enough to make the whole operation uncertain and rather dangerous. I don't think I'd try it, anyway.

I'd been assuming that they'd abuse the existing rules--Ravenclaw and Slytherin would agree not to catch the Snitch until both teams have racked up an obscene amount of points, and then they'd deliberately engineer a tie. This would both force a rule change and allow both to win the Cup.

But you've pointed out a potential problem: the tie can be broken by any professor. All McGonagall has to do, once she realizes what's going on, is promise to break the tie in favor of one side, and the other side will have no choice but to defect. Quirrel's bound by his promise not to award house points unfairly, but maybe he could blackmail Snape into promising to maintain the tie.

Something I've been trying to puzzle out for the past day, and failing. From Chapter 39, as Harry is talking to Dumbledore:

"The obvious test to see if the Resurrection Stone is really calling back the dead, or just projecting an image from the user's mind, is to ask a question whose answer you don't know, but the dead person would, and that can be definitely verified in this world. For example, call back -"

Then Harry paused, because this time he'd managed to think it through one step ahead of his tongue, fast enough to not say the first name and test that had sprung to mind.

Who was the first name (and test) that had sprung to Harry's mind? The quick rejection implies it would be something that would make Dumbledore think he is evil, or reveal to Dumbledore that Harry has some information that Harry doesn't want Dumbledore to know he has, or emotionally wound Dumbledore. And yet the shade would also have knowledge that no one alive would know, but the dead person would, and could be tested in the real world.

Things that have recently happened and might be on the tip of Harry's mind: Harry had a mysterious confrontation with Lucius Malfoy on platform 9.75, has met Neville's grandmother, and has discussed with Dumbledore what mischief Quirrell could unleash if he tricked the Headmaster into letting a Dementor onto the school grounds. They've also discussed immortality and afterlives (with some focus on Harry's parents).

Any guesses? I have a couple, but they seem quite weak to me.

HPEV was likely thinking of Merlin, but a much simpler test would be to call back Pierre de Fermat.

If you are creeped out, you are probably taking it out of context.

Sure, if you describe it as "he molested a minor and made her forget about it", it sounds quite creepy. But if you think of it as a lonely, inexperienced and deeply troubled boy thanking a girl fawning over him for her help in a tricky situation the best way he can, then maybe you will see that the difference in physical age does not automatically translate in this case into any kind of a power difference.

From chapter 76:

"I asked Professor Quirrell why he'd laughed," the boy said evenly, "after he awarded Hermione those hundred points. And Professor Quirrell said, these aren't his exact words, but it's pretty much what he said, that he'd found it tremendously amusing that the great and good Albus Dumbledore had been sitting there doing nothing as this poor innocent girl begged for help, while he had been the one to defend her. And he told me then that by the time good and moral people were done tying themselves up in knots, what they usually did was nothing; or, if they did act, you could hardly tell them apart from the people called bad. Whereas he could help innocent girls any time he felt like it, because he wasn't a good person. And that I ought to remember that, any time I considered growing up to be good."

Isn't this equivalent to renouncing Harry's entire rational approach of weighing costs vs. benefits?

In the chapter, what Harry is arguing is very different from what Quirrell said. Harry is arguing that Dumbledore is not optimizing correctly, presumably because he feels the pain of the deaths of his friends more than he feels the pain of all the things that were prevented by their deaths. Quirrell is saying, Don't try to optimize; just be free, amoral, and chaotic, and do whatsoever you will.

Yes. Which is why the very next thing Harry said was

"Don't worry, Headmaster," said the boy. "I haven't gotten my wires crossed. I know that I'm supposed to learn goodness from Hermione and Fawkes, not from Professor Quirrell and you."

According to you:

Quirrell is saying, Don't try to optimize; just be free, amoral, and chaotic, and do whatsoever you will.

The relevant quote would be from Chapter 20:

"What makes something right, if not your wanting it?"

"Ah," Harry said, "preference utilitarianism."

"Pardon me?" said Professor Quirrell.

"It's the ethical theory that the good is what satisfies the preferences of the most people -"

"No," Professor Quirrell said. His fingers rubbed the bridge of his nose. "I don't think that's quite what I was trying to say. Mr. Potter, in the end people all do what they want to do. Sometimes people give names like 'right' to things they want to do, but how could we possibly act on anything but our own desires?"

The talk about Fawkes also confused me. When Harry goes on to say that, next time, he'll do what he thinks Fawkes would do, that's also renouncing optimizing - in a different way. Fawkes doesn't plan ahead or optimize; it (Phoenixes are ) represents completely rule-based, not goal-based, ethics.

Phoenixes are parthenogenetic

How do we know this? They repeatedly burn themselves to rejuvenate but do we know anything about their reproduction. After being remade in fire it is the same phoenix.

Also, parthenogenesis isn't the same thing as hermaphroditic self-fertilization. If phoenices were parthenogenetic (which we have no reason to believe) that just means they would be female, not "it".

HPMoR phoenixes have a fairly thorough fire symbolism; the teleportation is compared to a flame extinguishing in one place and rekindling elsewhere. It seems reasonable to assume that phoenixes reproduce in the same way that flame spreads, kindling themselves wherever they can find a hero to burn for fuel.

I just thought the wording of 'phoenix's price' was auspicious, I agree that that's an interesting and poetic idea. (And looking back through, the fire symbolism is even more robust than I remembered.)

Problem: Dumbledore (who presumably should know) says in Chapter 62

"Harry," whispered the old wizard, "phoenixes do not understand how winning a battle can lose a war." Tears were streaming down the old wizard's cheeks, dripping into his silver beard. "The battle is all they know. They are good, but not wise. That is why they choose wizards to be their masters."

Edit: Does that make it clearer? I just thought the quote seemed to indicate a relationship other than 'use as fuel for reproduction'.

One thing that I've wondered about-and note that I'm not entirely sure if this is the right venue for asking- is what Eliezer thinks about the Visual Novel format a storyline structure (obviously not for MOR, that increases the entry barrier way too much for a cute and pop introduction to Rationality. ) I know that he decided to use the Normal/True ending for the Three Worlds Collide story, but what does he think about, let's say, the relatively long common route into different story branches format, the three "distinct" story format (Fate/Stay Night), or the "controlled redo format" (sort of like Tsukihime, where in order to get a complete idea of the setting, characterization and themes you need to finish all the routes in a certain order).

I half wish there's a magical encyclopedia for MoR like there was in Fate/Stay Night, but that's understandably not as fun to read or write as actually showcasing the powers.

Although talking about made me think: I totally want to see an Omake where Harry gets Bad Ended by getting addicted to video games after he goes back to his parents for the summer...

I seem to recall there was some playing around with Suzumiya-style Anachronic Order in earlier MoR chapters, but it was pretty self-contained and easy to follow. Plus there's some just downright confusing parts- chapter opening quotes that are never referenced again, Aftermaths that don't seem to have anything to do with the previous chapter, stuff like that.

And there's definitely some real potential for an omake chapter of Bad Ends: Harry accidentally destroying Dumbledore's ability to cast the Patronus Charm, Harry insulting his mother to Snape just a little more, Harry saying the wrong thing to Lucius in King's Cross, Harry realizing aloud to Quirrel what the ritual to summon Death really was...

The bit I'm referencing is from Chapter 28:

Earlier, Harry had very secretly - he hadn't even told Hermione - tried to Transfigure nanotechnology a la Eric Drexler. (He'd tried to produce a desktop nanofactory, of course, not tiny self-replicating assemblers, Harry wasn't insane.) It would have been godhood in a single shot if it'd worked.

Now, try to imagine Chapter28!Harry - after learning to lose, but before going to Azkaban and reconciling with his dark side - attaining "godhood in a single shot". How well do you imagine that might have worked out?

(This is leaving aside the myriad ways this scheme could have gone horribly wrong, of course. The point is, even if everything went according to plan it most probably would have been a Bad End.)

Assume Quirrell is not able to model 'good' people well -> we know he is not all powerful, and this is certainly where he is weak - witness conv with Harry on 'give a finger of my wand hand', 'does it really matter what your friends think', etc.

And each iteration with Hermione could have brought a different reason from Hermione, which was then subverted - we only saw one arc. Also H&C wanted Hermione as a willing participant, not as an NPC, much harder than simply memory charming her.

It's very unlikely EY has used two different H&C, and there was the 'wards keyed in' statement of both H&C & Quirrell earlier.

Will need much stronger evidence to say Quirrell is not H&C.

Zambini's actions during the Lake-Battle were not good for Quirrell. It did end in Harry hearing that Dumbledore acted dark, but Quirrell knows Harry well-enough to predict he wouldn't trust that information. So if Quirrell was really H&C, he should have had Zambini serving Potter all along so that Harry would win and be more likely to rule the country.

Blaise hesitated, but his curiosity was eating him alive. "Can I ask now why you want to cause trouble between Professor Quirrell and Dumbledore?" The Headmaster hadn't had anything to do with the Gryffindor bullies that Blaise knew about, and besides helping Kimberly, the Headmaster had also offered to make Professor Binns give him excellent marks in History of Magic even if he turned in blank parchments for his homework, though he'd still have to attend class and pretend to hand them in. Actually Blaise would have betrayed all three generals for free, and never mind his cousin either, but he'd seen no need to say that.

Downvoted for the attitude. People in LessWrong generally understand the difference between "evidence" and "indisputable proof".

When you say that "we should let this idea die already", are you actually claiming that the similarity of the H&C and Quirrell statements in regards to Slytherin's monster is exactly zero evidence towards H&C and Quirrel having some connection between them? Are you really saying that the author is exactly as likely to have H&C and Quirrel use the exact same phrase in regards to Slytherin's monster, if they were the same character, and if they were completely unrelated characters?

If you're not saying that, then all you're saying is that you feel it should be weighed as less significant evidence than how some people are weighing it -- but a mere disagreement on how it should be weighed doesn't justify your tone or the way you say "please let this idea die already".

Well, it's a historical fact that when I first saw this term-use-implies-identity idea, I rolled my eyes at it. What I think happens here is this:

The first appearance of H&C does indeed seem to imply Quirrell is H&C. He walks off after Zabini, Zabini's lie benefited him, and so forth. And however shakily, the common use of a term could support this as well.

But. Later we find evidence that it is indeed simply a technical term - as quoted above, (but it seems to be ignored, because the first H&C incident already implies a Q=H&C - at least I think this is what people feel), and then, in Ch76 we see something more important, a strong contrast between Quirrell reading the possibly-perfect-Occlumens Snape vs. H&C failing to read Hermione to such a degree that he needs to be told how suspicious he is. It points to them not beeing the same (which seems to be also ignored, because shared term-use already implies Q=H&C).

Rather than examining the evidences independently, they all seem to be lumped into an unassailable whole.

After listening to the podcast of chapter 35 I was sure that H&C was Quirrell. H&C told Zabini the slander about Dumbledor to tell Quirrell, and Quirrel knew that Zabini would slander Dumbledor when he talked to him. If Quirrell is not(or is not controlling) H&C then he would have had to find out the details of H&C's plot. Presumably there would have only been a single, surprised in the hallway, meeting between H&C and Zabini. The only options I see for Quirrell finding out about it is:

  1. Quirrell somehow knew the time and place that H&C chose for the meeting.
  2. Zabini became a Sextuple agent.
  3. Quirrell used legilimency on Zabini

1 Is unlikely considering the nature of the meeting. 2 is unlikely considering the inner thoughts of Zabini we have access to through the text. 3 is certainly possible since we only have Quirrell's own statement that the game would be boring as a reason he does not use legilimency.

Actually now that I think about it I am going to say that H&C is not Quirrell, and Quirrell knew that Zabini would slander Dumbledor because he used legilimency on Zabini.

I don't understand Draco's exchange with Lucius at the end of Chapter 7. Anyone know what's going on?

Here are my thoughts, which of course may easily be completely wrong.

Facts: 1) Harry states, "So during the Incident at the Potions Shop, while Professor McGonagall was busy talking to the shopkeeper and trying to get everything under control, I grabbed one of the customers and asked them about Lucius."

2) Harry states, "So you really are his one weak point. Huh."

3) Draco's letter to his father asks about Harry's "weak point" comment, Lucius's reply reads, "I would say that you had been so fortunate as to meet someone who enjoys the intimate confidence of our friend and valuable ally, Severus Snape."

--

Conclusions:

  • The wording of Harry's statement in fact 2 suggests that Harry's source put him on to the "weak point" assertion. The "so you really are" bit sounds like a hypothesis that has just been confirmed.

  • A bit of a reach: Harry's source in the potions shop was Severus Snape, and Snape is allied with Lucius. If the first conclusion is true, then this would explain the speed of Lucius's response to Draco. That is, Snape tells Harry about Lucius, including that Draco is his only weak point, and then reports the conversation to Lucius; when Draco reports the "weak point" comment, Lucius understands that Harry has spoken to Draco.

  • Snape is the potions teacher and hence might reasonably be found in the potions store.

--

This is not very satisfying to me because Harry doesn't later recognize Snape as being someone he has seen before, and his appearance is quite distinctive to Harry. Polyjuice seems like a stretch.

No secret information is required for Harry to come to his conclusion of "So you really are his one weak point. Huh."

Available evidence:

  • Lucius is well known as a hard bastard (initially supplied by random customer, reinforced by Draco)
  • Draco is well cared for (he is healthy, very well dressed, displays no social anxieties, worships his father)
  • Draco is probably indulged or even spoiled (Draco's behaviour)
  • Draco is being groomed to be Lucius' successor and therefore his equal (very clear by this point)

From this evidence it can be reasonably concluded that Lucius loves his son.
For a hard man like Lucius, this makes Draco his likely weakest point.

Lucius is simply underestimating Harry's ability to make good use of the available information (and possibly also underestimating how much Draco has given away while trying to cultivate Harry).

Nice. I like your explanation much better than mine. Keeping in mind that Lucius knows very little at this point about what Harry is like — and that Harry is only eleven! — I guess it's reasonable for Lucius to assume that such an observation by a fellow student of Draco's would require some adult tutelage.

I just realised that I missed another very strong piece of evidence which immediately precedes Harry's statement: Draco states that Harry should meet Lucius - he is actually offering Harry privileged access to his father.

This strengthens my view that Harry has noted that Draco offers (multiple paths to) influence with or threat to Lucius.

comment by TomM · 2012-01-24T00:08:49.889Z · LW(p) · GW(p)

Harry saying that Draco was Lucius' only weak point was probably just an (accurate) surmise given the available evidence:

    1. Lucius is well known as a hard bastard (information from random customer)
    1. Draco is visibly well cared for (and his behaviour suggests that he is indulged or even spoiled in many ways)
    1. Draco is being raised to be his father's successor and equal

Therefore Lucius probably loves Draco, making him a weak point.

No secret information is actually required to make this assessment, though it might be considered a bit close to a guess.

Harry has said that Hermione is his moral center. Is she? Should she be?

I have mixed feelings. She's hardly a paragon, and if she's going to continue to develop into her own character instead of a satellite of Harry, Eliezer's going to outline her faults in more detail. We've seen this with Harry. Every time he undergoes a trial, readers learn more and more how fallible he is, and why.

Hermione is far from perfect, but she's nonetheless the most traditionally-moral person at Hogwarts. I think Harry is correct not to want to emulate her entirely, yet still respect her enough to ask her advice on morally ambiguous issues.

""And," her voice said, "if you want to break school rules or something, you can ask me about it, I promise I won't just say no.""

perhaps eliezer's is not outlining but "fixing" her faults. by the end of ch75, hermione seems to have experienced a crisis of faith and become more morally harry.

Remember that being a good person, to Eliezer, is not just 'shut up and multiply'. For humans, it also requires having the sort of personality that does not allow you to pass a person in need without helping them. Hermione is such a person, and Harry realizes that he needs that if he doesn't want to stray from the path / become a dark wizard.

I have a hypothesis about the origin of magic.

Obviously it was a long time ago, presumably prehistoric. Could the creaters have been neanderthals? They died out comparatively recently, the soonest possible time being 30,000 years ago. Is this long enough for all traces of their civiliation to disappear? There is also strong evidence that many humans have some remains of neaderthal DNA (to fit with the Atlantis DNA hypothesis). They were physically dominant to Homo sapiens, which would make it easier for them to dominate technically as well. (In real life, their larger size required a larger calorie intake, which may have contributed to their extinction.) Whoever it was, somebody apparently reprogrammed the AI with pseudo-latin commands.

No.

If this hypothesis were true, we would expect to see no wizards among people of recent African stock, who do not have Neanderthal DNA, and this is not the case in the original canon, but that aside, the idea that a powerful AI was created by a species with markedly less cranial capacity and signs of advanced tool use than our own sounds highly implausible right off the bat.

Another possibility consistent with AA's idea is that the AI was created for the use of, rather than created by, the Neanderthals. Admittedly I'm now going down the AI-Designer-Of-The-Gaps rabbit hole, which suggests this line of reasoning is best discarded quickly.

Cranial capacity is about the same (reference wikipedia in my original comment). Also, our knowledge of their tool use is somewhat moot if we don't even know anything about a super advanced civilization. As in, what else are we missing about the past? The point about Africans is the strongest.

There's a decent chance you already know this, but that bit is probably a reference to Harry Potter and the Wastelands of Time. I don't think that fic describes what did its Atlantis in in any great detail (though it's been a year or two since I read it), but whatever it was, it was probably an apocalypse of subtype dug too deep and awakened an ancient evil. All the absurdly lethal skeletal guardians left lying around seem to point in that direction, at least.

On the other hand, there's enough references to D&D magic floating around that balefire wouldn't be too outré.

But there's no shortage of people who could accomplish it cooperatively, if you get male and female channelers working together.

I'm sure that in Wheel of Time there were plenty of ways to obliterate a city with the One Power back in the Age of Legends. The issue isn't that it can obliterate cities, but that if you use it for wholesale destruction like that, unlike, say, explosions, it fucks up the very fabric of reality.

There seems to be a slight contradiction.

On the one hand, Harry and Hermione find out that one needs to know what a spell does in order to cast ist successfully (Ch 22, "If you didn’t tell her at all what the spell was supposed to do, it would stop working.").

And then in 26, about the 6th years Griffindor (canon!Harry) who hexes canon!Draco: "He is in his sixth year at Hogwarts and he cast a high-level Dark curse without knowing what it did.”

Shouln't that be impossible? Or if the knowledge from Harry and Hermione's experiment wasn't very general, Harry should have noted at least. (Though honestly I didn't notice during my first read, being amused about the reference to canon).

The next line after "If you didn't tell her at all what the spell was supposed to do, it would stop working." says

If she knew in very vague terms what the spell was supposed to do, or she was only partially wrong, then the spell would work as originally described in the book, not the way she'd been told it should.

Knowing that the spell is 'For enemies' apparently counts as knowing in very vague terms what it will do.

Dumbledore tells Harry that Voldemort has used Dark Magic to save his own 'soul' at the cost of Myrtle's life. So Harry knows of at least one Dark Ritual which needs a death as sacrifice, ie making a Horcrux.

Quirrell tells Harry that the darkest ritual he knows requires only a sword that has slain a woman, and a rope that has hanged a man - to summon death.

Since Harry knows Quirrell knows every Dark Ritual there is worth knowing, and one of the rules of Evil Overlords is to get immortality, Harry knows that Quirrell is not telling him about the Horcrux ritual. If he puts the 'where to hide a Horcrux' & 'the lose 5 things' bits together, he will know he can never kill QuirrellMort, since he's unlikely to get to any of the Horcruxes anyway.

I don't think making a Horcrux qualifies as a ritual. And if it did, it requires one death whereas the one Quirrell mentions requires two (albeit indirectly and with the possibility of them not being murders).

He probably is hiding some darker rituals, but I doubt the making of Horcruxes is one of them.

Also, he could be judging the ritual most terrible on effects rather than sacrifices, and Quirrel's worldview obviously judges summoning Death, especially without the dismissal, as more terrible than making yourself some flavor of immortal.

There seems to be only one way this story can end.

  • Eliezer is concerned with people building AIs that have tremendous power.
  • The powerful wizards in HPMoR represent the AIs.
  • Harry wants, and appears destined, to become the singleton AI.
  • Eliezer believes that any AI that is not provably constrained, by its design, to follow rules that lead to , will inevitably - and I use that word to mean "with such high probability that you shouldn't even think about the cases where it doesn't" - lead to violating those rules.
  • Harry cannot be redesigned from the ground up to provably implement any ethical system.
  • Therefore, for Harry to do anything other than destroy everything that we, the readers, hold dear, would go against everything Eliezer has written about AI.

(It could alternately end with Harry killing himself and Voldemort, neutralizing Voldemort and giving up his own power, letting Voldemort kill him on realizing that Voldemort is less of a threat than he himself is, or in some other way kicking the problem down the road for the next generation. But the only final resolution of the story's central theme that is consistent with Eliezer's writings seems to be for Harry to destroy the world.)

The powerful wizards in HPMoR represent the AIs.

No he doesn't. He's just an AI creator. If he was representing an AI the entire story would have been over at Chapter 1.

Eliezer would not write a parable in which an AI made a slow journey to power, on the way learning valuable moral lessons through social interaction with the people he cares about. That completely undermines all that he stands for.

  • Therefore, for Harry to do anything other than destroy everything that we, the readers, hold dear, would go against everything Eliezer has written about AI.

Harry destroying the world would make a reasonable conclusion albeit for different reasons than Harry being an AI. That said, the lesson to be learned is too complicated for fanfic readers to be expected to learn from just a story. It is hard to convey that Harry made the correct decision to try to save the world even though he failed and destroyed everything because the alternative was certain failure and at least his chances were better than that.

Which reminds me: I hope there is a chapter in which Harry (or someone else) loses something dramatically but realizes (or has Harry explain to them) that they made the right choice anyway. And the converse in which a decision is wrong even though it turned out well.

Harry is not an AI creator. That would require him to create an AI. There is no AI in the story, and no hints that there will be any AI. Harry is on his way to achieving personal power, without any technological intermediator.

Eliezer would not write a parable in which an AI made a slow journey to power, on the way learning valuable moral lessons through social interaction with the people he cares about. That completely undermines all that he stands for.

Why? Do you think Eliezer believes AIs are incapable of learning valuable moral lessons through social interaction with the people it cares about? Presumably, even within Eliezer's model, an AI can be moral and kind and loving to humans for some time period. If you think that "unfriendly AI" will necessarily be amoral and incapable of love - well, that's just silly. The reasons for believing that are exactly the same as the reasons for believing that computers can never be intelligent.

As to "slow", that's just one of the things that scales differently because of the analogy being used.

I believe Eliezer would rather dip his... arm... in a vat of acid than suggest to his readers that an AI will act like a clever well intentioned child that learns valuable moral lessons through social interactions with those he loves, over a long period of a slow, rather inefficient quest for power.

Please cool it down a bit.

Just two chapters ago, Harry was compared to a all-powerful summoned entity that knew nothing about how humans worked and so had to be taught not to eat people and stuff. Hermione accepted that comparison as somewhat fitting. So the comparison of Harry to non-human intelligences is MoR!Canonical, even though it was a huge exaggeration even within the context of the story, expressed by people genuinely scared of Harry -- the Harry who seemed more powerful than a Nameless Horror and might need the magical nations of the world to ally against him in order to seal off his incursion into our reality.

I don't think you get it. If you think you can substitute "write something slightly at odds with his beliefs into a fanfiction" even remotely appropriately into that context then you do not have enough knowledge about Eliezer's publicly expressed goals to be making the kind of moral judgement you presume to make.

I wrote my claim because it sounds like a hyperbole but isn't. For the right value of 'acid' my claim is a literal counterfactual prediction. And I don't mean a "dipping his arm in vinegar" technicality. I'd estimate the approximate value of acid required to make the preference stand is something that would fall short of leaving permanent scars but give him significant pain for a week. Maybe that is a little light... perhaps leaving some scarring but leaving full function and sensitivity on the hand so he can still type. Just so long as some of that typing constitutes a massive disclaimer and retraction to undo some of the damage his toxic propaganda would have done.

I said Harry represents an AI. You said Harry is an AI creator. I was just taking you at your word. It didn't occur to me that you meant Harry represents an AI creator, because that wouldn't make any more sense. Harry does not represent an AI creator unless he creates something that is in some way analogous to an AI. There is no hint he will do that. Harry is not creating an AI, and is not creating anything analogous to an AI.

Whereas Harry has properties analogous to a recursively self-improving AI on the way to having godlike power. And the danger that Harry will pose once he attains these godlike powers is one of the central themes of the fanfic, and is highlighted throughout the entire fanfic, over and over again.

I believe Eliezer would rather dip his... arm... in a vat of acid than suggest to his readers that an AI will act like a clever well intentioned child that learns valuable moral lessons through social interactions with those he loves, over a long period of a slow, rather inefficient quest for power.

The slowness is due to humans, who represent the AIs, operating only at human speeds, and does not detract from my point.

I still have the impression that you think Eliezer's view implies that an AI cannot be well-intentioned, or learn valuable moral lessons through social interactions with those he loves. Why? That is exactly as absurd as saying that computers can never be intelligent. (I am ignoring questions of whether a computer program can subjective experience love, since "love" used as a verb refers to the action rather than to the subjective experience. But, still, anyone who follows Eliezer at all should be a materialist and therefore believe that a computer program can in principle love as well as a person can.)

I'm not convinced of your second point. Powerful MoR wizards aren't nearly as constrained as people in our world, but the only person in the story that's explicitly trying to act as a optimizer over a generalized utility function rather than to achieve some set of concrete goals -- that is, the only person acting as Eliezer's concept of AI would -- is Harry himself. There are a number of ways that plot thread could be resolved, but destroying the world as we know it isn't the one I'd bet on -- although I'd expect the threat of such destruction to come into play at some point down the road.

We've also seen Eliezer's take on the Dark Lord-as-optimizer concept play itself out once before, in "The Sword of Good", and that -- avoiding spoilers -- didn't seem to resolve in a way consistent with your premise.

"A rationalist!hero should excel by thinking - moreover, thinking in understandable patterns that readers can, in principle, adopt for themselves." - Eliezer

I think Harry is supposed to be a rationalist!hero. I think he's supposed to succeed in the end. The fact that he also has the potential to be very dangerous and destructive is, I think, just about the dangers of power itself, and the importance of ethics + reason in making decisions. Especially when you have something to protect.

I think Harry's ethics are actually not too far from EY's. Of course he has ethical failures and character flaws, and that pesky dark side, but he's mostly headed in the right direction. And though he's quite unusual, he doesn't have some sort of inhuman psychology. A protagonist's quirks are often exaggerated, because stories have to shout.

I don't think he represents an AI at all.

Harry James Potter-Evans-Verres' morality is to Eliezer Yudkowsky's morality as Paul Muad-dib Atreides' is to Frank Herbert's.

(That is, both Harry and Paul are heroes, and have hero morality. They have their view of a horrifying future they may cause: the jihad, and becoming a new Dark Lord. But they have a desire to make things better as well - well, Harry more so than Paul. And in reading their story, you are supposed to fall into the same trap they do - thinking that if they just try hard enough, they can still do good, still have an impact, still be a hero, without bringing about the horrible future. And so they aim closer and closer to that horrible future, looking for the edge of the circle where the bad thing doesn't happen but they are still a hero, with a hero's legacy - when what they should be doing is making the bad future as unlikely as possible, not making the bad future only just barely fail to happen!)

The bit where Eliezer isn't a character in a novel.

Sure UFAI pattern-matches to the Dune jihad better than anything in HPMoR, but even then Eliezer isn't acting like Paul at all. A Muad-dib!Eliezer would be working feverishly in the basement of the fortified SIAI bunker (which would actually be a cult) to put together an "at-least-it-isn't-paperclips-forever" AI before the US government finds his location and drops a bunker buster on him. Right about now we would have tense negotiations with national entities grimly ending in Eliezer pressing the On switch.

This sounds nothing like what is actually happening, does it?

Well, no. (Hopefully not. Not as far as I know, anyway.)

The point I was making was less about the similarities to Dune (which I shamefully have only a vague knowledge of) and more about this assertion:

I think Harry's ethics are actually not too far from EY's

Harry James Potter-Evans-Verres' morality is to Eliezer Yudkowsky's morality as Paul Muad-dib Atreides' is to Frank Herbert's.

Cause see, the thing is, Harry isn't working feverishly in a bunker, either. I guess the question is: what do you think Eliezer would do differently in Harry's situation?

Edit: I've just realized I anchored onto the wrong part of that analogy. It may actually be fair to describe Harry's recent approach as leaning towards "tense negotiations with national entities grimly ending in ... pressing the On switch." Um. So.

I'm not going to retract, but I think I've got more of an appreciation for your point of view, now.

For the life of me, I can't find it - but there is a comment from EY about HJPEV's actions (appearing suboptimal in some commentor's view because he was busy winning a school wargames competition instead of Transfiguring more carbon nanotubes and building supercomputers and space elevators) to the sarcastic effect of "It's almost as if he's not me!".

This is what prompted me to compare Eliezer's HJPEV to another author's "supposed-avatar-but-actually-the-author-is-smarter-than-that" character.

I think the Sword of Good focused on the question of how culture can blind our moral sensibility. I would say that story just wasn't about that problem.

It is true that neither the Lord of Dark in that story, nor Harry in MoR, is expected to enter into the rapid recursive self-improvement anticipated for an AI. Though I would expect MoR's Harry to figure out a way to do that, given wizardly powers over time.

I think we can all agree that Harry's inability to accept natural death as a good thing (hubris) is an impossible trait for a young boy to have unless they have been exposed to great evil.

I expect it to later be revealed that Harry's inability to accept the natural order is due to Voldemort's horcrux being placed within him. When he is healed of it he will probably remain intelligent but stop being power-hungry/evil.

First: is the parenthetical comment meant to be a summation of the previous term? Second: agreed, as long as the definition of "great evil" includes the fact that roughly a hundred and fifty thousand people die every day.

I expect it to later be revealed that Harry's inability to accept the natural order is due to Voldemort's horcrux being placed within him. When he is healed of it he will probably remain intelligent but stop being power-hungry/evil.

This is an interesting idea, because Harry's inability to accept the natural order was explicitly stated to be the reason he could cast the True Patronus Charm. Is that part of what you refer to as "power-hungry/evil", or...?
