Harry Potter and the Methods of Rationality discussion thread, March 2015, chapter 116

post by Gondolinian · 2015-03-04T20:11:04.153Z · LW · GW · Legacy · 306 comments

This is a new thread to discuss Eliezer Yudkowsky’s Harry Potter and the Methods of Rationality and anything related to it. This thread is intended for discussing chapter 116.

There is a site dedicated to the story at hpmor.com, which is now the place to go to find the authors notes and all sorts of other goodies. AdeleneDawner has kept an archive of Author’s Notes. (This goes up to the notes for chapter 76, and is now not updating. The authors notes from chapter 77 onwards are on hpmor.com.)

Spoiler Warning: this thread is full of spoilers. With few exceptions, spoilers for MOR and canon are fair game to post, without warning or rot13. More specifically:

You do not need to rot13 anything about HP:MoR or the original Harry Potter series unless you are posting insider information from Eliezer Yudkowsky which is not supposed to be publicly available (which includes public statements by Eliezer that have been retracted).

If there is evidence for X in MOR and/or canon then it’s fine to post about X without rot13, even if you also have heard privately from Eliezer that X is true. But you should not post that “Eliezer said X is true” unless you use rot13.

"Let's see how you like everyone thinking you defeated the Dark Lord and you not remembering it." -Harry

comment by Gondolinian · 2015-03-04T22:21:43.129Z · LW(p) · GW(p)

On /r/HPMOR, some have been speculating that Dumbledore coated the Philosopher's Stone with Bahl's Stupefaction, which you might remember from chapter 63:

"Bahl's Stupefaction," Moody said, naming an extremely addictive narcotic with interesting side effects on people with Slytherin tendencies; Moody had once seen an addicted Dark Wizard go to ridiculous lengths to get a victim to lay hands on a certain exact portkey, instead of just having someone toss the target a trapped Knut on their next visit to town; and after going to all that work, the addict had gone to the further effort to lay a second Portus, on the same portkey, which had, on a second touch, transported the victim back to safety. To this day, even taking the drug into account, Moody could not imagine what could have possibly been going through the man's mind at the time he had cast the second Portus.

This would explain why Voldemort let Harry keep his wand after swearing the Unbreakable Vow, and now also might explain Harry's recent actions.

But it's not an idiot ball if there's an actual legitimate reason for being stupid.

Like, in The Naked Time and The Naked Now, the initial infections were pure idiot ball.

The subsequent infections, and the crew doing spectacularly stupid and even suicidal things, were not.

I kind of wish Harry just figured out how to escape earlier. It would have been awesome for him to end the Unbreakable Vow by transfiguring the other wand into a flashbang.

Oh. I was expecting something like...


Chapter 116, alternative version

Harry spun his Time-Turner and returned six hours into the past. Then he took his broomstick and hurried towards Hogwarts.

This time he decided not to repeat his usual mistake. If Lord Voldemort could learn, so could Harry. He didn't have to solve all the problems of the world alone. And Professor Quirrell, his alter ego, was not the only available option.

He hesitated a bit before knocking on Headmaster Dumbledore's door. This is going to be so awkward, he thought. He tried to imagine what to say. Hello, Headmaster. Professor Quirrell is Lord Voldemort, and I have killed him in the future. By the way, it was me in Azkaban, sorry about it, I didn't know back then. Anyway, you are going to die in the mirror soon. To avoid a time paradox, could you just send a copy of yourself or something? Please hurry, we don't have time, you have to trust me! Ironically, that would sound really insane, but Harry now trusted Headmaster Dumbledore to be able to deal with the news. Dumbledore was willing to sacrifice his own life, if it meant destroying the Dark Lord, but Harry hoped there would be a way to avoid it. The timeline had to proceed as Harry had experienced it, but if it turned out that what Harry believed to be real people were instead merely convincing illusions, then no one had to die. Maybe he could also save Lucius Malfoy, or even all the Death Eaters.

Then Harry noticed the door was open. He slowly walked inside the dark and seemingly empty room. Maybe he should write a message and leave it on the desk...

The door suddenly shut. A person standing in the dark was pointing a magical wand at Harry.

"Drop your wand immediately. Then don't move. We have to talk."

Harry's brain was so shocked that only afterwards he realized his fingers have already obeyed the command automatically.

"Yes, Harry, always playing one level higher than you," Professor Quirrell said, smiling. "I see you have returned from the future, which obviously means that my plans didn't work as expected. That is an admirable achievement. Now you are going to explain me all that happened in future, in Parseltongue. And then I will see what I can change to preserve your experiences while giving myself a more favourable outcome."


This is the second part of your exam. You have 60 hours. Your solution must allow Lord Voldemort to survive the following six hours without creating a paradox in timeline, without losing his consciousness or magical abilities. Otherwise you will get a shorter "Voldemort was defeated and they all lived happily ever after" ending.

The following chapters 117, 118, 119, and 120 will contain the remaining four parts of the exam, where you will solve even more complicated problems from the viewpoint of Headmaster Dumbledore, Hermione, Severus Snape, and Minerva McGonagall. The last chapter 121 will contain a surprising revelation that all of them are actually horcruxes of Baba Yaga. Oops, sorry for spoilers.

Harry only has one hour left on his Time-Turner for the day; he used five hours to do everything he did with Voldemort after Voldemort sent him the forged note at the Quidditch game earlier.

Hardest part to fake is Harry's sense of doom/scar pain/resonance: there probably has to actually be a Riddle in the Voldemort-body as it gets stunned, obliviated and transfigured. Better make sure it's a Horcrux V1 copy. So bring a V1 Horcrux, use it to overwrite the Voldemort body you create with the Stone, then possess that body on top of the Riddle already in there, then abandon ship right before the stunning hex.

"Harry, let me verify that your Time-Turner hasn't been used," said Professor McGonagall.

I think there is a very good chance that McGonagall is worried enough about Hermione, about Dumbledore, ... and won't check Harry's Time-Turner. She's not much into multilevel plots, she's smart, but too honest to live in constant suspicion.

Like she didn't think much about the consequences at the "war level" when she offered the fealty oath to Hermione back then in the Wizengamot.

She sees Harry in pain and traumatized, and she sees the immediate chaos, it wouldn't be very "in character" for her to suddenly suspect Harry and probe him like that.

It could happen because she learned to not follow her "role" anymore, but it still doesn't seem the most likely thing for her to do.

Moody or some aurors on the other hand...

I think that McGonagall has learnt enough to be suspicious of Harry, but she's still more circumspect than to call him on it in front of the whole school. Maybe she'll check up a bit later, and maybe in private Harry will be happy to tell her the truth anyway, with appropriate precautions. On the other hand, if he's decided not to tell her, then he'll arrange not to be found until it's too late. (When is it too late to check if a time turner has been used?)

comment by Duncan · 2015-03-04T21:16:21.765Z · LW(p) · GW(p)

A story for the masses is necessary and this doesn't appear to be a bad stab at one. Harry can always bring trusted others on board by telling them what actually happened. He might have actually done that already and this is their plan. How much time did Harry have to do stuff before needing to show up anyhow (40m? 50m?)? Also, Prof. McGonagall is terrible at faking anything so telling her the truth before this seems like a bad idea.

It seems that death eaters have "anti-time-looping wards" (chap 94), we don't know exactly how they work, nor if they were used in the graveyard, but it could very well be that no time-traveler can check the events that happened on the graveyard.

I myself will guard this place until six hours have passed, for I do not fully trust the wards I have set; and four of you shall search the surroundings for signs of anything noteworthy.

Would you risk going back to a live LV just to check it out? Take the risk that Harry didn't notice some annoying bystander get dispatched, or just didn't mention it? A lot of those revelations only came out when the subject came up, after all. Using a Pensieve would be much safer.

Snape isn't, because he can't apparate from Hogwarts. Amusingly, Snape may interpret his exclusion from the mass sacrifice as a deliberate "kindness" from the Dark Lord.

Harry can just claim to have already used it that day for an innocuous purpose, like studying or something. Sure, McGonagall could accuse him of stupidity because that leaves him unprepared for an emergency, but pleading guilty to stupidity is easy. (Well, easier, anyway.)

Unclear. Either midnight or as soon as last 24 hours contain less than 6 hours of looped time. I've been wondering this as well. I think I remember something being said like "No combination of time-turners could let you fit more than 30 hours into a day" but I don't know if that really helps...

Where is that written? I well remember that no chain of time turners can send information (at least information comprehensible by humans) back more than 6 hours, but that still allows one to add those 6 hours more than once a day, especially with multiple time turners.

Ch 17:


"...Sorry to ask but I was wondering, is it possible to get more than six hours if you use more than one Time-Turner? Because it's pretty impressive if you're doing all that on just thirty hours a day."


"I'm afraid Time doesn't like being stretched out too much," said Dumbledore after the slight pause, "and yet we ourselves seem to be a little too large for it, and so it's a constant struggle to fit our lives into Time."

Thanks, but that's not actually definitive. Somewhere on Reddit is a list of information about time turners, and while this was quoted there, nothing else suggested that you couldn't go back 6 hours, wait 12 hours, then go back 6 hours with a new time turner.

But there was a clear statement by Eliezer that you couldn't go back 6 hours, wait only 6 hours, and then go back again. This imposes a hard limit of 48 hours per day.

Nope, you're right. It's not definitive. In my original comment, I just said I thought I remembered reading somewhere that you couldn't fit >30 hrs into a day, and the passage I quoted is where I got that impression. If /r/hpmor thinks it's possible that TTs let you fit up to 48 hrs in a day, then I have high confidence there wasn't anything explicitly forbidding it in the story.

Just to be clear, the Reddit thread didn't say that you can fit 48 hours in a day, it just didn't say that you couldn't. And it probably had that Dumbledore quotation too, it's just me saying that we can't know for sure what that quote means.

The stage seems to be set for a sequel adventure series, The Three Immortals. Three great heroes, each blessed with a fragment of immortality, work together to fend off the forces of destruction and bring true immortality to all of humanity.

Unicorn Girl, filled with the life-giving, regenerative powers of two noble magical creatures. Her mind captures everything that she sees, with amazing fidelity, while the purity of her heart pulls her to do what's right with similar fidelity. Some call her "mudblood", in honor of the ancient myths about the creation of man from earth, because the power to re-create herself flows continuously through her veins.

Mr. Physics, the culmination of the great Peverall line which has sought immortality for generations, is the heir to many great and powerful magical artifacts. But it is his deep and detailed knowledge of the laws of the universe which grants him his greatest power - the power to make anything out of anything, even reshaping his own body. He has made a solemn vow to protect humanity, with Unicorn Girl as his moral compass.

The mysterious Cloud has dark secrets which are hidden even from himself, but his mind still holds a wealth of ancient lore to share and an intellect so sharp it can cut through any facade or riddle... except perhaps his own past. This great mind is backed up, a hundred times over, in a vast network which allows him to be reborn in full force should his body ever fail him. The first to reach immortality, Cloud helped bring both his companions into their powers.

Well, for a start there is the Phoenix Sage, that fallen champion of Light sworn to protect mankind from the "curse" of immortality at any cost. Once sealed away beyond time and space, he now returns to seek his vengeance, wielding both ancient lore and the misguided adoration of the masses as tools in his quest to end our heroes' ambition. With his revival, ally after ally is falling back under his spell, lured in by honeyed words of false wisdom and by memories of the days when he shone so bright. How will the Three Immortals expose his hypocrisy and defeat him, when he has managed to corrupt even the very symbol of Light and immortality, the Phoenix itself?

Yeah, and not just that. The magical equivalents to forensic science would have to be terrible indeed if this works, with a lot of fail from intelligent people like Bones, Moody, or for that matter Snape.

I'm kinda hoping that what we're actually heading for in the next chapters will be some kind of payoff to this:

But there are a very few, seated on those wooden benches, who do not think like this.

There are a certain few of the Wizengamot who have read through half-disintegrated scrolls and listened to tales of things that happened to someone's brother's cousin, not for entertainment, but as part of a quest for power and truth. They have already marked the Night of Godric's Hollow, as reported by Albus Dumbledore, as an anomalous and potentially important event. They have wondered why it happened, if it did happen; or if not, why Dumbledore is lying.

And when an eleven-year-old boy rises up and says "Lucius Malfoy" in that cold adult voice, and goes on to speak words one simply would not expect to hear from a first-year in Hogwarts, they do not allow the fact to slip into the lawless blurs of legends and the premises of plays.

They mark it as a clue.

They add it to the list.

This list is beginning to look somewhat alarming.

Since Dumbledore didn't give anyone else access to an undisturbed scene, it's merely the best conclusion that anyone could draw who wasn't an actual professional investigator / smart person.

Actual professional investigators would know not to come to any conclusion without actually investigating the scene. (Whether or not they trusted Dumbledore to investigate is a different matter.)

Smart people would think:

They have already marked the Night of Godric's Hollow, as reported by Albus Dumbledore, as an anomalous and potentially important event. They have wondered why it happened, if it did happen; or if not, why Dumbledore is lying.

What do you mean? He narrated the whole sequence before the explosion, and fell to his knees at the moment Voldemort supposedly died, which is coincident with the explosion. I don't see a problem, let alone one that would be fixed by shifting the narrative back 20 seconds.

Due to the finite speed of sound, the explosion would have had to occur approximately 20 seconds before they heard it. So if Voldemort's death was coincident with the explosion it would had to have happened about 20 seconds before Harry said it did.

She'd just about decided that this had to all be a prank in unbelievably poor taste, when a distant but sharp CRACK filled the air. [...] "It worked," Harry Potter gasped aloud, "she got him, he's gone." [...] "I think it's in that direction." Harry Potter pointed in the rough direction the CRACK had come from, "I'm not sure how far. The sound from there took twenty seconds to get here, so maybe two minutes on a broomstick -"

Well, that's certainly one way to explain away all of the strange aspects. Establish them as fact, through the mysterious bond between LV and HP, and do so in front of a huge crowd so that the word can spread and mutate on its own. By the time anyone comes to investigate or question, they will already be influenced by the show or rumors they've heard, promoting that hypothesis to their attention rather than coming to it naturally.

It's pointing the police at Mortimer Snodgrass, from chapter 17, as it were.

It's actually the same tactic as the Weasley twins used to cover the "engaged to Ginever Weasley" story- plant so many make newspaper reports that everyone gets confused.

Prediction 1: Hermione will soon harrow Azkaban. Why wouldn't she? She's all but immortal, now.

Prediction 2: Time-travel and memory-charm shenanigans incoming. Evidence:

  • Harry weirdly ignored the missing recognition code on LV's forged message.

  • Cedric considered in Harry's plans, and his Time-Turner mentioned, then seemingly forgotten.

  • Death-Eaters all dead, but no faces observed.

  • Flamel asserted dead, but we didn't see it, and LV explicitly didn't kill him personally.

  • Dumbledore thinks in stories, yet we're supposed to believe he's surprised when the villain reveals he's captured the hero and his equipment (Harry and the Cloak), just like villains always catch heroes and take their stuff near the end (see: Frodo Baggins, Luke Skywalker).

  • Hermione has been asleep the whole time, neither giving nor receiving information.


  • did Harry tell Cedric to do certain things before Harry left? Did Harry tell Cedric to Obliviate Harry afterward so Harry could play his part convincingly? What did Harry most likely tell Cedric to do?

  • who will do the Time-Turning, Hermione, Cedric, or Harry?

  • who will be saved? Obvious candidates include Flamel, Dumbledore, Lucius Malfoy, maybe all the anonymous Death-Eaters.

  • if you were Hermione and had a Time-Turner and the Stone and the Cloak and six hours to save everybody but Voldemort, Quirrell and Macnair, how would you do it? (Do you need the help of someone who can Obliviate well? Do you need partial Transfiguration?)

The Cedric situation hints strongly at information control, maybe to deal with the six-hour limit on Time-Turners.

if you were Hermione and had a Time-Turner and the Stone and the Cloak and six hours to save everybody but Voldemort, Quirrell and Macnair, how would you do it?

Being Hermione makes this harder. There's a way to do it: find a morgue, transfigure the bodies into simulacra of the Death Eaters, give permanency with the Stone, raise them as Inferi, then use Horcrux 1.0 castings with a respawning Hermione as fuel to copy the original Death Eaters' mind-states. But Hermione doesn't have the power, doesn't know that kind of Dark magic, and has way too many ethical scruples; and we don't know the Horcrux enchantment in enough detail to know that it's exploitable in that way. (You don't need the Horcruces to fool physical examination, but I assume Voldemort has some way of sensing people's minds or magic.)

It also might not account for everything it needs to, given that Harry feels what I assume to be their deaths on-page. That could be the Horcrux enchantment dissipating, though.

Or, a simpler solution: travel back six hours, Obliviate Voldemort while he's on the toilet (he could probably resist Imperius at full power), Imperius him to do everything Harry remembers that involves personal agency except summon his mooks, then false-memory-charm Harry into thinking thirty-six Death Eaters were present when they weren't. Take office as Hogwarts' first Professor of Retconjuration.

This is not how (Harry's) recognition code works. It is used to identify exact(ish) copies of himself because he is the only one - barring magical mental shenanigans - that can immediately recognize it. Writing it down on a piece of paper and then giving that piece of paper to someone else would defeat the purpose entirely.

The "potato" code, yes.

But knowing that Harry is "be prepared" so much that he prepared a recognition code when he didn't think he would ever use it, and then had been nearly a year with a time-turner, and knowning about Oblivatiate, it's quite surprising that he didn't device a recognition code to recognize a message sent either by a future self to his past self (time-turner) or from his past self to his future self (Obliviate).

comment by Nornagest · 2015-03-06T17:53:13.621Z · LW(p) · GW(p)

The cryptographic solution to this problem is to publicize related codes derived in such a way that the possessor of the secret code can recognize the derivation, but bystanders can't use them to rederive the secret code.

It's probably a bit much to expect Harry to use that in its strong form -- most of the relevant math was known in 1991, but it only rose to prominence with the Internet, and it's quite laborious by hand -- but there's probably a similar ad-hoc scheme he can use that'd provide reasonably strong authentication against a bunch of cryptographically naive wizards.

The niave protocol, any time you get a note, you come up with a random password. That password has to be on the bottom of the note. If the password has even a few bits of entropy, relative to outsiders, this will work. (Memory charms or time turners can get around this, but its still a good precaution)

The fact that he uses prime factorization as his test for "can use you time turner to solve computationally hard problems" is evidence that he did know about prime number based cryptography, not strong evidence, but evidence still, since the prime-based crypto is the most common reason people are interested in having fast ways to factor primes.

For all practical uses x'=(x*8+1) mod 49 is a simple PRNG that can be executed mentally easily. If you seed it with the next best number you see it gives suitably random numbers for every-day purposes (and when no dice are available). Note that this is taken from TAoCP by Knuth.

I don't like things which use apparatuses because they introduce a dependency (and since this scheme is for use in extreme/unusual circumstances, it's especially likely that Harry would not have leisure time or access to his pouch) and they make part of the process observable, hence, easier to realize the existence of & reverse-engineer.

A fully mental PRNG is doable under all circumstances in under a second and is unobservable except via Legilimency (which if it isn't blocked, means one is screwed anyway since one can just be False-memory-charmed into remembering having done the verification*).

Hermione is a rule follower. She wouldn't destroy Azkaban if she had a button she could press that would do so.

She also knows exactly what it's like to be an innocent sentenced to Azkaban for a crime they didn't commit, and how easy it is for such a thing to happen. You can't go through an experience like that without re-evaluating some things about how you see the world.

Also she can't kill even one Dementor, or even cast a patronus to prevent one from killing her.

The point of the above post, I believe, is that there is nothing stopping her from learning to cast Patronus 2.0, at which point it's plausible that the infinite unicorn blood would replenish her life-force so killing Dementors wouldn't end up draining it all.

No magic burst at death would be one prediction to check, though not conclusive. You could test it with Horcrux 2.0, though no one has had the opportunity to do that before now. The fact that Voldemort has expressed uncertainty about whether he is capable of surviving dementors, and that he is relying upon escaping from Quirrel's body in time to survive dementors points in the direction of him believing that a dementor might be capable of taking out him and his whole horcrux network in one shot.

None of that is conclusive, but it's all suggestive and supports the popular version of what dementors do.

The thing about magic burst is that Dementors drain the target's magic anyway. It's entirely plausible that if a Dementor kills you, it sucks away your magic in the process, or at least enough of it to prevent a magic burst.

I just noticed something:

Chapter 79:

When he was alone in the room, the old wizard looked down at the map, which had now written upon itself a fine line drawing of the Gryffindor dorms in which they stood, the small handwritten Albus P.W.B. Dumbledore the only name left therein.

The old wizard smoothed the map, bent over it, and whispered, "Find Tom Riddle."

Chapter 108:

"Yes," Harry said in an even voice. "What did you do to the Weasley twins? Dumbledore thought - I mean, the school saw the Headmaster go to the Weasley twins after Hermione was arrested. Dumbledore thought you, as Voldemort, had wondered why Dumbledore had done so, and that you'd checked on the Weasley twins, found and took their map, and Obliviated them afterward?"

"Dumbledore was quite correct," Professor Quirrell said, shaking his head as though in wonderment. "He was also an utter fool to leave the Hogwarts Map in the possession of those two idiots. I had an unpleasant shock after I recovered the Map; it showed my name and yours correctly! The Weasley idiots had thought it a mere malfunction, especially after you received your Cloak and your Time-Turner. If Dumbledore had kept the Map himself - if the Weasleys had ever spoken of it to Dumbledore - but they did not, thankfully."

It seems like Dumbledore knows quite a bit more than Voldemort thought. Did he know Q=V and HJPEV=TMR?

And finally, Chapter 110:

"I am there," Albus Dumbledore said, "and also inside the Mirror, unfortunately for you. I have always been here, all along."

Always? That's an odd turn of phrase. Who was elsewhere?

I've been wondering about this for a while, but never had a chance to do the required detective work. Were Harry and the Defense Professor in the castle at the time? If so, when Dumbles said "Find Tom Riddle..." he most definitely learned that HP and QQ were both Tom Riddles.

Hum, good question.

I assumed that with all his experimenting he did in a year, he must have triggered a ward at a point. He doesn't all the wards, and since we expect them to be quite extensive, it's very unlikely he never triggered one.

So what are our hypothesis ?

  1. Harry is not recognized as Defense Professor by the wards.

  2. Harry is recognized as DP by the wards, never triggered a ward, but that didn't seem suspicious to Dumbledore because there are fewer wards I imagined there to be, so even with lots of experimenting, it's quite normal he didn't trigger one.

  3. Harry is recognized as DP by the wards, never triggered a ward, and Dumbledore failed to realize it, due to a variation of the "availability bias", we don't tend to notice events that fail to occur (while they should) as much as events that occur (while they shouldn't).

  4. Harry is recognized as DP by the wards, and Dumbledore did suspect it. Then, Dumbledore knowing that Harry is likely a Tom Riddle, must have suspected Quirrel to be a Tom Riddle. He knew much more that he claimed, and he lied when he said to Quirrelmort that he didn't suspect anything.

I would put most probability on 1, but none of 2, 3, 4 can be excluded at this point, yes.

I do not expect this. Time-tuners are fine. Invisibility cloaks are fine. Draco's torture hex was fine. The only thing I can think of that Harry did that might have triggered a ward without permissions was bring in the transfigured unicorn. And that isn't conclusive at all. It was transfigured, and as far as I know the Defense Professor can't just bring magical creatures in to Hogwarts either.

I don't think it's been tested.

We have some evidence Harry has defense professor permissions and didn't trip any wards because of that. He practiced memory charms. In Hogwarts. If the castle thought of him as a student, that would have set alarms ringing, with professor permissions, no alarms. Not strong evidence, because Harry was Dumbledores pet disaster, and it is entirely possible he'd hear an alarm like that, check up on what Harry was doing, and ignore it as long as he wasn't casting it on students.

I've been re-reading the fic, and the science conspiracy idea shows up early on.

Quirrel in chapter 20:

"There are gates you do not open, there are seals you do not breach! The fools who can't resist meddling are killed by the lesser perils early on, and the survivors all know that there are secrets you do not share with anyone who lacks the intelligence and the discipline to discover them for themselves! Every powerful wizard knows that! Even the most terrible Dark Wizards know that! And those idiot Muggles can't seem to figure it out! The eager little fools who discovered the secret of nuclear weapons didn't keep it to themselves, they told their fool politicians and now we must live under the constant threat of annihilation!"

Harry gets on board with the idea in chapter 23:

"The secret of blood," said Harry Potter, an intense look on his face, "is something called deoxyribonucleic acid. You don't say that name in front of anyone who's not a scientist..."

Naw, they still wouldn't want to leave him in Harry's care.

What will Snape do now that he's no longer in love with Lilly?

Nothing. They are no longer counting on him to protect Harry from a returned Voldemort. Unless you mean whether he is going to evolve as a person and maybe develop a love life.

How was magical Italy ruined 323 years ago, or does it matter?

I suspect it was only an example of how yes, Potterverse magic can be that destructive (something we would not guess based on canon).

Quirrell teaching students the Killing curse...will it matter?

Unlikely. Knowing the Killing Curse is perfectly legal, and a lot of people have managed to learn it even though it is not taught in school. Come to that, the information we have suggests that it is also perfectly legal to use, just not against humans (unless they are Death Eaters, assuming the Monroe Act hasn't been repealed).

Why did the rememberal go off?

Because Harry has a lifetime's worth of lost/repressed Tom Riddle memories. We know that they're still in there somewhere, because he recovers the memory of his imprinting and of the locations of Voldemort's five "elemental" horcruxes.

Did Harry time-turn the day Hermione died, and, if so, what did he do?

Yes. When he went into the room with Hermione's body, he turned the time turner and transfigured her body into a ring while also transfiguring something else (presumably something very small) into a copy of Hermione's body. He then hid from his past self and left the room just after his past self entered. After the transfiguration wore off, the 'body' dissapeared.

After rereading, I beleive that Mr White is Lucius Malfoy. Not only is the name an allusion to his hair, he is said to be less useful than he was in the past due to the fact that V will soon rule openly. In the past Lucius was V's puppet in the Wizengamot.

Mr Write then proceeds to sacrifice most of his magic to bind Harry Potter. I suppose with him dead, this doesn't matter.

Interesting hypothesis... but if the wards didn't identify Harry as the "Defense Professor", and identified the troll as "Defense Professor". So I guess the wards identify the bodies more than the "spirit" inhabiting them, which means they won't recognize Voldemort now that he left Quirrel's body to his original snake-like body.

comment by UnclGhost · 2015-03-05T18:29:12.154Z · LW(p) · GW(p)

I guess the only other evidence we have is that the Map, using the wards, would (implicitly) alternate between showing him as QQ and TR depending on whether QQ was being actively possessed, but as far as we know reported relatively consistently on the presence of the Defense Professor, such that it was a surprise to Dumbledore that the wards reported him being the troll. We do know that the wards are able to remain aware of identity even through transfiguration, as shown with both the troll and the unicorn.

It seems like that's about as consistent with the hypothesis "the wards counted QQ's body, QQ's suppressed consciousness, TR's consciousness, and the troll as the Defense Professor" as it is with "the wards just counted QQ's body and the troll as the Defense Professor". It comes down to whether it's more likely that the wards use the simpler strategy of tracking bodies (as Velorien said) since there would be little reason to track spirits/consciousnesses, or that they target your magical "self" as well as the Map seems to do, possibly based on some fundamental aspect of magical self-ness.

Of course, all this is even assuming the wards track the deaths of professors. It seems like the sort of thing you'd want wards to do, but I can't think of anywhere that that's been confirmed. We do know that the wards didn't report that the Defense Professor died after the troll died, so if it does keep track of the deaths of professors, it doesn't count as death when some living portion of "the Defense Professor" is still alive.

comment by Velorien · 2015-03-05T13:47:29.808Z · LW(p) · GW(p)

Given that Voldemort is the first known wizard to successfully move between bodies, it's unlikely that the wards would have been calibrated to track that sort of thing.

It's a nice story. But it won't work.

Harry wants folks to think LV killed the death eaters and not him. But he has trained Draco too well. Given priors on someone defeating Voldemort you would assume it's Harry, DD, or QQ in that order. Draco knows Harry and QQ were up to something because he and several other kids bumped into them and had a scuffle at the third floor corridor. If that wasn't entirly obliviated away, Draco will figure out that Harry was involved.

I was wondering if one of the things Harry would do with his extra hour was a Patronused message to Lucius to "Stay where you are, remain silent, do not respond to the Dark Mark, for one hour, if you want to live." Or even better, a message to Draco to send that message to Lucius, except Draco is probably still sleeping off Harry's stunner.

In any case, under the circumstances, Harry might be able to trade the whole sad story, including confirmation of Dumbledore's ordered killing of Narcissa (now that Dumbledore is gone) for Draco's forgiveness.

Since time loops are stable, no reason not to try. Even if Mr. Counsel is Lucius, the most stable time loop is that Lucius doesn't believe the Patronus and gets killed anyway, and then Harry can at least truthfully tell Draco he tried.

A fair point (and upvoted), but since Harry will still have killed Lucius if he fails, it'd still be best to try to hide the whole thing from Draco. But yes, try (since he doesn't know for sure who Counsel is), and tell Draco that he tried if Draco figures it out, but don't tell him otherwise.

comment by Astazha · 2015-03-05T03:10:33.575Z · LW(p) · GW(p)

So, I don't know how these stable time loops are supposed to work. My working model is that they function by trial and error, that time iterates through a universe until it encounters paradox, at which point it returns to pre-paradox, inserts some change into the world through prophecy or whatever, and tries again. This continues until a stable timeline is found, with an unknown number of them being discarded/destroyed. It appears from within that things worked on the first pass, but they did not. Our viewpoint never follows into one of those dead ends, but they exist(ed).

If the world really works that way, Harry would be potentially throwing his victory away by forcing a paradox. Time would have to reset to before the paradox and insert a change into the world to ensure a different outcome. He may or not be victorious in that new timeline. Harry dying was already a high probability and it would certainly resolve things to Time's satisfaction. His best chance of securing his immediate past as part of the real and continuing world would be to make sure this timeline remains self-consistent.

(Plus, he's prophesied to destroy the stars and creating a time-paradox seems like a really obvious possible way to do that.)

The only other possibility I can think of for these apparently stable timelines is that the whole universe is pre-determined and no one has any free will at all. I read something from EY about universes with time travel and he seemed to be in support of this second possibility. Any other possibilities for how this would work?

I think that the trial and error model is implausible; in which "time" are these trials and iterations occurring? The global determination of the whole universe seems much simpler.

I don't think it necessarily conflicts with free will, when free will is understood in a compatibilist way (which is how EY and most LWers understand it). If we agree that one can have free will in a completely deterministic universe with ordinary past-to-future causal chains, then why can't one have it in a universe where some of the chains run future-to-past?

That's a good link, thanks. I'm warm to compatibilism. I think I've confused the conversation by using the wrong terms, though. Instead of pointing at a lack of free will I should have pointed at the complete lack of causality, which is more constraining. You can read EY on it here.

My interpretation of this would be that space-time would be a fixed object that exists in it's entirety. In the same sense that you could take a cross sectional scan of a sneaker and play it from rear to front, there would be a logical consistency to how the slides transformed as you progressed through the shoe, but it would not make any sense to say that one part caused another. In this analogy, 4-dimensional space-time is the shoe, and the cross section is 3-dimensional space. We play it from back to front, watching a movie of the universe, but the entire universe from beginning to end already existed; we're just looking at a slide of it at a time. Everything is consistent as the cross section passes through, but there's no causality in play, it's just an object being viewed in sequential slices. Much like EY's modified game of Life with time-travel.

This actually seems pretty unsatisfying because there is a strong impression that the world is being run mostly on causality in the normal direction, with reverse causality coming in occasionally. This seems to me to work better with the iterating model.

Regarding the time for trials and iterations, I would refer to simulation as an analogy. "World time" is happening in the simulation, and this is what the characters are aware of. From within the simulated world, how much "Meta time" has elapsed outside of the simulation (i.e. the time stream that the computer is in), or how many failed attempts have been dumped from RAM is not very relevant in the sense that these facts don't have any impact on "the world" (the simulated one) and are in fact probably unknowable to its inhabitants unless access to that meta-information has been somehow granted. To a denizen of the world, the fact that we switched from world version 721.213 to world version 779.344 last Tuesday at 9:41am is unknowable, the transition seamless, the lost attempts erased from world time even though they still occurred in meta time.

I'm not saying HPMOR is a simulated world. That's just a model I'm using to think about timelines being destroyed and recalculating.

The nature of causality is controversial, but in my opinion it should be understood as a feature of the second law of thermodynamics. That causes precede their effects is an empirical law, not a logical necessity. Time turners can violate this in certain ways, but they don't throw it out entirely.

As you look through the block universe, you can observe various features corresponding to causality: the increase in macroscopic entropy, the expansion of radiation, the human creatures inside that remember the past and plan for the future. The block universe model doesn't eliminate causality; it is a physical feature within that universe.

All that has to happen is that there is some entity that behaves and responds in the same way that Mr. Counsel does. While it might be likely that the Mr. Counsel character is Lucius, there is nothing in the laws of time that prevent the person under that hood from being someone else - particularly because Harry took care not to look closely at the remains of the decapitated death eaters.

My first thought was about the centuries-old theatre trick: Harry hides a few drops of red paint in one hand, presses that hand on his forehead because “the scar hurts” … and voila, a bleeding scar.

Your thought seems simpler, though, as well as plausible:

The pain that flashed through Harry's scar was searing, it made him cry out and a red haze appear across his vision

I'd say your first thought was right.

She noticed half an hour later on, when Harry Potter seemed to sway a bit, and then hunch over, his hands going to cover up his forehead; it looked like he was prodding at his forehead scar. The thought made her slightly worried; everyone knew there was something going on with Harry Potter, and if Potter's scar was hurting him then it was possible that a sealed horror was about to burst out of his forehead and eat everyone. She dismissed that thought, though, and continued to explain Quidditch facts to the historically ignorant at the top of her lungs.

She definitely noticed when Harry Potter stood up, hands still on his forehead, and dropped his hands to reveal that his famous lightning-bolt scar was now blazing red and inflamed. It was bleeding, with the blood dripping down Potter's nose.

Harry Potter, however, if he makes himself immortal, will have a lot of time. Even if a lot of people die of old age or illness before he can reach them, he can still reach a lot of people given enough time.

This also explains why Flamel only interferes in politics by teaching chosen champions - She is still bound by the goblet rite on the Battle Magic position, so that is the only way she can oppose dark lords that don't show up at her door and try to kill her.

But I would suggest that, narratively, the defeat of Baba Yaga by sixth-year Perenelle exists as a clue for the plausibility of the defeat of Voldemort by first-year Harry Potter.

Why I think he's doing this :

  • so Draco doesn't know that Harry probably killed his father ; Harry values his friendship with Draco and doesn't want to lose it ;

  • so Harry doesn't have to tell everyone about his secrets (like partial transfiguration) ;

  • so they don't search for Harry for the transfigured Voldemort ;

  • so Harry doesn't have too many legal/political problems for actually killing dozens of people, including some very powerful ones ;

  • to give some credit and status to Hermione, which at this point Harry trusts more than himself to take the ethical decision (and not destroy the world) ;

  • to save the image of Quirrel, I think Harry still has emotional commitment to the character of Quirrel, even if it was just a mask, and doesn't want that image to be destroyed.

Well, people are less likely to believe in an idea if an argument used in favor of it later turns out to be entirely false. For example, if I say "green jelly beans are slightly carcinogenic" and someone says "yes, also each one you eat has a 1/100 chance of killing you immediately", makes a lot of publicity about this, and months later it turns out that that statement was completely unfounded, then people will be less likely to believe me now. Even though they have very little new information compared to just me saying "green jelly beans are slightly carcinogenic".

So in this case we have people saying "Look, some Slytherins are good, see QQ!", and gaining some amount of support with that. QQ turning out to be Voldemort would not only defeat everything the argument did (which is not bad in and of itself, the argument was after all flawed), but also cause a backlash which would make Slytherin appear worse in comparison to before QQ was the Defense Professor.

Hm.

I think his contribution to public perception would have been "some Slytherins are incredibly badass" rather than "some Slytherins are good".

Voldemort was in Slytherin and claimed to be Slytherin while impersonating QQ. The actual QQ was known to be Ravenclaw:

Quirinus... Quirrell," drawled the man now sitting across from where the Defense Professor had waited courteously. The interrogator had tawny hair that swept back like a lion's mane, with yellowish eyes set into the sternly lined face of a man late in his tenth decade. The man was, at this moment, leafing through a large folder of parchments that he had taken from a black and very solid-looking briefcase after he had limped into the room and sat down, seeming not to look at the face of the man he was interrogating. He had not introduced himself.

After some further leafing through parchments, carried out in silence, the Auror spoke again. "Born the 26th of September, 1955, to Quondia Quirrell, of an acknowledged tryst with Lirinus Lumblung..." intoned the Auror. "Sorted into Ravenclaw..."

Okay, Harry is really overdoing it here. It would have been much safer to pretend utter ignorance of everything, or at least to limit his reaction to falling over. The scene as set will cause sufficient theorizing without trying to force a particular narrative.

On a meta level: Getting this scene from a bystander means they are not in the mirror. So that's that.

I.. also just realized that "Flamel" can't possibly be dead. The rite Voldemort used on Hermione was not one of his own devising, but a piece of lore well known enough to have a usual result. "Flamel" had the stone of permanency for either 600 years, or much longer than that. And has more lore than Voldemort.

The best creature to assume the essence of from a defensive standpoint isn't a troll or a unicorn. Tough, heck, if there is no downside to just stacking things, maybe she did. The creature in the potterverse with the most absolute defense is the phoenix. Fiendfire? Firetravel away. AK? Respawn and laugh. So Dumbledore may have seen Flamel die, but that means absolutely nothing.

.. depending how the sacrifice works, this might not even hurt the phoenix you are using! Well, permanently anyway.

That objection notwithstanding, the most plausible non-Voldemort killer would be Bellatrix, using her superpower of very strict obedience to orders like "Just use AK and do not hesitate for any reason".

The relevant section (Ch 108):

Next you will ask why I did not kidnap, torture, and kill Perenelle after I learned the truth."

This had not in fact been a question that had come into Harry's mind.

Professor Quirrell continued to speak. "The answer is that Perenelle had foreseen and forestalled the ambitions of Dark Wizards like myself. 'Nicholas Flamel' publicly took Unbreakable Vows not to be coerced by any means into relinquishing his Stone - to guard immortality from the covetous, he claimed, as if that were a public service. I was afraid the Stone would be lost forever, if Perenelle died without saying where it was hidden, and her Vow prevented attempts at torture.

Perenelle's safety relied on the Stone's uniqueness and hiddenness, which is no longer a factor as far as Quirrell is concerned.

I did not attack her directly, for I was not sure of my great creation; it was not impossible that I would someday need to go begging to her for a dollop of reversed age.

  1. Voldemort is unlikely to destroy what he could instead steal.
  2. Voldemort is unlikely to leave power around where others can find it (and then use it against him).
  3. There are potentially many vengeance spells that Flamel has set up in order to dissuade anyone from killing them.

The obvious plan is to steal Flamel's lore and then induce Flamel to commit suicide. Legilimency serves for both purposes. This may be blocked by Occlumency or Dumbledore's intervention, but using a controlled minion to simply kill Flamel seems to go against point 1.

The most obvious interpretation is that V just sent B to kill F, or Owled F a hand grenade, or so on. But I don't see why V would prefer that option, especially given that even in the world where V has F's lore, V would want Dumbledore (at least) to believe that F's lore is gone.

Eh.. Voldemort is a legimens. But he isn't an unusually good one at all. He actively dislikes actually reading peoples minds. He simply had a very impressive talent for entirely non-magical cold reading and inference. The wizarding public heard tales of that, and in the same way they failed to consider "hidden broomstick enchantments!" credited him with scary superpowers he didn't actually have.

This is an inference from the text, but a high probability one. - However, it is also stated outright in the text that Harry's mental defenses are nothing special. He's an occlumens, but according to his teacher in that art, who bloody well should know, not a perfect one.

The latter statement isn't evidence for the former. Harry dislikes broomstick riding as an activity, but is still naturally gifted at it, and successful on the occasions when he needs to do it.

Here is our best example of Voldemort talking about his abilities:

Then in fury I threw aside masks and caution, I used my Legilimency, I dipped my fingers into the cesspit of his stupidity and tore out the truth from his mind. I did not understand and I wanted to understand. With my command of Legilimency I forced his tiny clerk-brain to live out alternatives, seeing what his clerk-brain would think of Lucius Malfoy, or Lord Voldemort, or Dumbledore standing in my place.

That sounds pretty advanced to me, and the way he speaks of it ("with my command of Legilimency") suggests pride in his abilities as well.

Here is Moody talking about Voldemort's abilities, with Dumbledore listening and not disagreeing:

“And I’ll warn you of this but once. Voldie isn’t like any other Legilimens in recorded history. He doesn’t need to look you in the eyes, and if your shields are that rusty he’d creep in so softly you’d never notice a thing.”

We are never told what the wizarding public at large thinks of Voldemort's Legilimency powers, so I don't know where you're getting that argument.

And for the record, this is Mr Bester's assessment of Harry:

You may indeed be able to learn Occlumency at eleven years of age. This astounds me. I had thought Mr. Dumbledore was pretending to be insane again. Your dissociative talent is so strong that I am surprised to find no other signs of childhood abuse, and you may become a perfect Occlumens in time.

It's also worth noting that while Moody doesn't seem especially impressed at the power of Harry's Occlumency barriers, his only comment is that they are rusty, not that they provide insufficient protection for practical purposes.

I've argued before that HPMOR probably includes some kind of mind/body dualism. It occurs to me that an interesting experiment is about to be performed.

The body of Hermione Granger has been infused with the life and magic of Harry Potter. I assume for narrative reasons that Hermione will wake up as Hermione. But a copy of Harry could wake up in Hermione's body instead.

The mechanisms behind a person' life force, magic force, and mind are unknown to us. We don't also don't know whether or to what extent these aspects of a person are separate or connected. It should be assumed throughout this post that I am talking about the minds of magical people, and that muggles could be a separate case.

If Hermione wakes up as Hermione after being resurrected by Harry's life force and magic force I will conclude:

  1. A mind is probably not made up only of a person's life force and/or magic force. The only exception I can think of is if the mind runs on a substrate of your life and/or magic force but the Patronus 2.0 or resurrection process strip that information out of the projected life and magic, passing the substrate but not the pattern on it.

  2. Either the mind has at least something to do with the body OR magic will, upon resurrection, retrieve the mind that is supposed to go with the body OR Harry's intent is sufficient to establish what was supposed to happen here.

  3. Related to #1, atomic souls in the sense of "an animating force that contains a person's life, magic, and mind all in one non-physical object that persists beyond that person's death" would be ruled out. Life beyond death would not be ruled out, but souls could not be things with no smaller components if they exist at all.

  4. I would update to consider possibilities like "your mind is just your brain but magic stores it in other dimensions or on a magical substrate when required" more likely than I previously did.

If Hermione wakes up as a copy of Harry in Hermione's body I will conclude:

  1. Mind/body monism is almost certainly false. Your mind is not your brain in any sense; the brain is at best an interface that the mind uses or a home that it resides in. Monism could only be rescued if magic turned Hermione's brain into Harry's brain during the resurrection process.

  2. Your mind either is inseparable from your life and/or magic or it is a pattern on a life/magic substrate that is transmitted with that subtrate through the Patronus 2.0 resurrection process.

  3. I will update to consider atomic souls as described above to be more likely than I previously did.

Separately, in a world with mind/body monism, I wonder whether regeneration as a magic that always transfigures you back into yourself would prevent learning. Probably not. Magic tends to have the intended effect rather than a strictly mechanistic one.

Above is the Doyalist reason, and almost certainly the root reason.

The Watsonian reason was that it would force Voldemort to waste an hour in the preparation, making any attempt to steal the Stone take an hour longer. As traps go, it's reasonably clever.

The potion did serve its in-story purpose of banishing the flames blocking the doorway, after all, so it's not like Voldemort spent that time on the potion and then used his wand to take care of the flames.

The Ravenclaw team put up a valiant fight.

But there was no Quidditch team anywhere that could've defeated the Slytherins that day.

Dawn was tinging the sky when the Slytherins won their final game, the Quidditch Cup, and the House Cup.

I read this as metaphorical, with Harry the Slytherin-just-kidding-Ravenclaw going Slytherin, but I don't see exactly how that fits.

I think it's pretty obvious.
Voldemort has always been attracted to power, and it's well known that Hermione is the most powerful witch of her generation.
He made several overtures to her, but was unable to turn her from her path, and so he killed her.
Upon her death he felt great remorse (such was his passion) and decided to bring her back from the dead (such was his power).
Dumbledore tried to stop him, and so was eliminated.
In fact, Voldemort was so enamored of Hermione, that after she was brought back, he use dark magics to give her even greater power.
Quirrell (who has been hiding his identity of David Monroe) was secretly on hand for the ceremony, but by the time he realized what was happening, it was too late to stop it.
Cutting charms were used on Voldemort's hands, and other terrible damage, but despite all this, Quirrell was defeated.
Ironically, having given her the power of friendship, it was the power of friendship which ultimately was his downfall.

The annihilation of Quirrell!Mort (assuming that is what's happened) isn't something I can envisage as being part of Quirrell's plot. So, although the outcome Quirrell was aiming for coming to pass would make it look like he was successful in fact his plot failed and Harry's plot on his behalf succeeded.

It can be argued that Quirrell manipulation of Harry to ensure Quirrell was seen to win was a strand in Quirrell's plot. But, his fear of death / destruction of his horcrux was so profound my model of Quirrell wouldn't perceive himself to have won under these circumstances.

Failed, I think. As of 104, it looked like his Christmas plots were all going to succeed - the Ravenclaws and Slytherins were in the process of tying for the Cup, and raising the popularity of Harry's anti-snitch proposal in doing so.

It is only the revelation that "Professor Quirrell had gone out to face the Dark Lord and died for it, You-Know-Who had returned and died again, Professor Quirrell was dead, he was dead", which Quirrell would not have planned around, that threw a spanner in the works by motivating the Slytherins to seek outright victory.

The "luminous white quiver running over the holly" and "drifting motes of silver light like tiny specks of Patronus Charm" when Harry Obliviates Voldemort in Chapter 115 are not normal for Obliviation. 90%

The following seems like a very obvious observation, but I don't recall seeing it made so far.

Tom Riddle Jr #1 (aka Lord Voldemort, aka Quirinus Quirrell) attempted to create an intelligent being in his own image, with the intention that it would share his values and cooperate with him in bringing about the sort of future he wanted.

This didn't go well, for reasons including (1) that Tom Riddle Jr #2 turned out not to share TR#1's values after all, and (2) that TR#2 developed new abilities TR#1 never suspected and that TR#2 was able to use against TR#1 when they happened to come into conflict.

Oh, and TR#2 might just destroy the world.

Application of all this to a problem Eliezer is known to be interested in is left as an exercise to the interested reader.

(The suggestion that Harry might be kinda like an UFAI has been made here before and my response was that Quirrelmort was a better candidate. But Quirrelmort is probably out of the picture at this point.)

I'm not actually sure any more. Was Voldemort really unaware that Harry could Partially Transfigure Things?

I will note that Quirrel watched over Harry as he felled a bunch of trees in Precautionary Measures pt.2. And that involved partial Transfiguration.

"Silence!" shouted Professor McGonagall at the podium of the Head Table. "No talking until the Sorting Ceremony finishes!"

There was a brief dip in the volume, as everyone waited to see if she was going to make any specific and credible threats, and then the whispers started up again.

Then the silver-bearded ancient stood up from his great golden chair, smiling cheerfully.

Instant silence. Someone frantically elbowed Harry as he tried to continue a whisper, and Harry cut himself off in mid-sentence.

The cheerful-looking old man sat down again.

Note to self: Do not mess with Dumbledore.


"In Hogwarts, Dumbledore does punish certain transgressions against his will, so he is feared to some degree - though the students still make free to mock him in more than whispers. [...]

Harry hadn't been like that around Professor McGonagall... who admittedly had the power to deduct House Points and didn't have Dumbledore's air of tolerance... no, it was still true, Harry would have been more respectful even in his own thoughts if Dumbledore had not seemed safe to disrespect.

But we've seen internal monologue from Harry where he thinks about the intrinsic value of Voldemort's life and the values of the children's children's children and so on. It's incredibly naive. Voldemort is an immortal psychopath who is ridiculously overpowered and very difficult to contain. Taking that guy out is entirely in sync with valuing life in general.

It seems unlikely, but then so is thinking with the brain of a cat, so who knows? If Obliviate works by altering brain states, and Magic recognizes a dead brain (so long as not too far decayed) as still a brain with all of its prior states from when it was alive, then it just might work.
