Dumbledore (who has used Transfiguration in combat and lived) gave Harry his father's rock the day after Quirrell publicly accused Harry of always thinking purely of killing and novel ways to do it. I don't know if D wanted to encourage H in this, or to provide an alternative to some more dangerous action. (Maybe D has considered the possibility that Q has some dark reason for wanting Harry to learn the Killing Curse?) But I feel very sure that he was thinking of the use H did in fact make of it, and we don't need to imagine another purpose.
If anything, Dumbledore would want to keep the Philosopher's Stone more directly under his control, eg hidden under the lampshade in his office.
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 96. The previous thread is at almost 300 comments.
There is now a site dedicated to the story at hpmor.com, which is now the place to go to find the authors notes and all sorts of other goodies. AdeleneDawner has kept an archive of Author’s Notes. (This goes up to the notes for chapter 76, and is now not updating. The authors notes from chapter 77 onwards are on hpmor.com.)
The first 5 discussion threads are on the main page under the harry_potter tag. Threads 6 and on (including this one) are in the discussion section using its separate tag system.
Also: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, .
