Self-locating beliefs across identity fission

lukeprog

From Wolfgang Schwarz's Belief Dynamics Across Fission:

Fred’s home planet, Sunday, is surrounded by two moons, Monday and Tuesday. Tonight, while Fred is asleep, his body will be scanned and destroyed; then a signal is sent to both Monday and Tuesday where he will be recreated from local matter.

A lot of ink has been spent on how to describe scenarios like this. Should we say that Fred will find himself both on Monday and on Tuesday? Which of the persons awakening on the two moons is identical to the person going to sleep on Sunday? In this paper, I want to look at a different question: what should Fred’s successors believe when they awaken on Monday and on Tuesday? More precisely, how should their beliefs be related to Fred’s beliefs before he went to sleep on Sunday?

It seems better to consolidate these posts into bibliography posts by subject, perhaps updating the old posts. The single-paper posts clog Discussion too much.

ETA: on further consideration, I hold this view less strongly.

I feel that it's better to err on the side of posting too much rather than posting too little. High posting frequency is probably the number one thing that a blog-based community needs to stay alive. (Quality is also important, but that is hardly an issue in Luke's case.)

I feel slightly more motivated to read these papers if they're presented one at a time.

I don't see a problem with someone saying (implicitly) "hey, I spotted this paper I found interesting on this topic of local interest" and don't see it as "clogging" Discussion.
