Also, there's another respect in which foundation doesn't impact Russell issues at all. Whether one accepts foundation, anti-foundation or no mention of foundation, one can still get very Russellish issues if one is allowed to form the set A of all well-founded sets. Simply ask if A is well-founded or not. This should demonstrate that morally speaking, foundation concerns are only marginally connected to Russell concerns.
To make the obvious comment, this is all unnecessary as Russell's paradox goes through from unrestricted comprehension (or set of all sets + ordinary restricted comprehension) without any talking about any sort of well-foundedness...
But that's a neat one, I hadn't thought of that one before. However I have to wonder if it works without DC.
Edit: Answer is yes, it does, see below.
Update: Discussion has moved on to a new thread.
The hiatus is over with today's publication of chapter 73, and the previous thread is approaching 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 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. 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:
