New long chapter! Since I expect its discussion to generate more than 160 comments (which would push the previous thread over the 500 comment limit) before the next chapter is posted, here is a new thread.
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 108 (and chapter 109, once it comes out on Monday).
EDIT: There have now been two separate calls for having one thread per chapter, along with a poll in this thread. If the poll in this thread indicates a majority preference for one thread per chapter by Monday, I will edit this post to make it for chapter 108 only. In that case a new thread for chapter 109 should be posted by whoever gets a chance and wants to after the chapter is released.
EDIT 2: The poll indicates a large majority (currently 78%) in favor of one thread per chapter. This post has been edited accordingly.
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Eliezer Yudkowsky which is not supposed to be publicly available (which includes public statements by Eliezer that have been retracted).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.
Agreed, and I want to expand that a little:
Muggle science determined that muggle minds are contained in muggle brains, and Harry has been reluctant to let go of this idea even though there are observations against it and he has seen that magic can freely violate very solid muggle conclusions like conservation of matter.
Even if muggle brain damage seems to damage the mind, it could be that it damages the mind's interface to the body. Here in the real world, this dualism adds additional complications and doesn't help explain any evidence. In the HPMOR universe there is a great deal that would be explained by mind/body dualism.
Animagus transfigurations almost require it. Skeeter's mind is not contained in the physical arrangement of a beetle's brain. Therefore, her mind isn't just a physical brain in this world. Her brain could be held in some extradimensional pocket and interfacing to the beetle. Her mind could be running on a magical, rather than physical substrate (always or just during transformation?). She could have a soul. (And some versions of "mind on a magical substrate" would also qualify as "souls".)
As DanArmak says, Quirrel didn't just have backups of himself in Horcruxes, he was able to think and perceive while this was his only form of existence. Those copies were running, thinking, planning. They were also connected to each other, and still are. Quirrel was not revived from the Pioneer horcrux, but he has the memories of the Pioneer horcruxes experiences. The pioneer plaque or a pebble or whatever is not a physical substrate that a mind can run on by any natural-to-muggle-science means. Again we have dualism. Brain in another dimension, magical substrate, soul. And brain in another dimension gets pretty strained here, I think.
Here Quirrel's mind is totally disembodied through the help of the Resurrection Stone.
Ch. 1:
I observe a world where minds are not just physical arrangements of brains. The "we are just our brains" hypothesis is being falsified all over the place in HPMOR.
For me there is no question about whether disembodied minds exist in this universe. My questions are whether minds are disembodied all the time or just when magic requires it. Whether muggles also have disembodied minds that are just much more inaccessible to observation. "Minds are always disembodied" seems more elegant by far than magic translating your physical brain into another equivalent form and creating an interface between that and your body only during animagus transformations and other such events, translating that back when returning to human form, and your mind just being a brain at all other times. That would be way more complicated than dualism.
