Harry Potter and the Methods of Rationality discussion thread, part 23, chapter 94 — LessWrong

It occurs to me that I've seen very little mention of one major dangling plot thread: The Interdict of Merlin. Bypassing the interdict may get Harry sufficient power, without necessarily getting at 'the source of magic' or becoming omnipotent.

There's some precedent for this: partial transfiguration, patronus 2.0, and acorn brewing were all made possible by understanding something others did not. It's possible that the Interdict is something similar, and that Harry will be able to understand his way through it.

This mechanism appears to have been used in other of Eliezer's works as well, for example the "Jeffreyssai" stories in the Sequences.

Prediction: by the end of the story, Harry will somehow have managed to dispell the Interdict of Merlin. Given his opinions on muggle society that gains power with each generation, versus wizard society that loses power with each generation, there is no way Harry is going to let that stand. Given that it was brought about by magic, presumably it can be cancelled by magic, and Harry will find a way.

Although not instant win, beating the interdict is potentially a route to great power fast. I think its a more likely route because its more fuzzy. The 6 hour limit on turners is a hard rule, there is not a lot of room for subjective interpretation to play with. The partial transfiguration trick works because form and object and the like are fuzzy concepts that don't map exactly onto anything in the real world. The limit on the transmitting of "sufficiently powerful spells" seems very similar in that its based on an idea without an exact referent. Sufficiently powerful compared to what, compared to a candle? Compared to a gun? Compared to a nuke? Compared to a meteor? Compared to a supernova? If Harry calibrates powerful based on a supernova and really "gets" how powerful that is, do all spells seem piddling by comparison and pass through the edict unscathed? There's certainly room to work with here.

The problem is that "bypassing the Interdict" is not, on its own, useful; it's only valuable if Harry happens to have written notes on powerful magic spells that are censored by the Interdict. Apparently, there's a loophole allowing Interdict-restricted material to exist (wizards can keep notes for themselves, implied by chapter 23), but it seems unlikely that Harry would be able to get ahold of much of it. (Possible exception: Bacon's diary? Quirrell didn't think Bacon found much of interest, but he could be wrong.) Related: since Muggle physics can apparently contribute to powerful magics (see: partial transfiguration) would the Interdict apply if Harry ever wrote a physics book? What would the Interdict do if a Muggle happened to accidentally write (presumably as fiction) the details of a powerful magic spell? Can Muggles read Interdict-restricted works?
