This is a thread for discussing my luminous!Twilight fic, Luminosity (inferior mirror here), its sequel Radiance (inferior mirror), and related topics.
PDFs, to be updated as the fic updates, are available of Luminosity (other version) and Radiance. (PDFs courtesy of anyareine). Zack M Davis has created a mobi file of Radiance.
Initial discussion of the fic under a Harry Potter and the Methods of Rationality thread is here. The first dedicated threads: Part 1, Part 2. See also the luminosity sequence which contains some of the concepts that the Luminosity fic is intended to illustrate. (Disclaimer: in the fic, the needs of the story take precedence over the needs for didactic value where the two are in tension.)
Spoilers are OK to post without ROT-13 for canon, all of Book 1, and Radiance up to the current chapter. Note which chapter (let's all use the numbering on my own webspace, rather than fanfiction.net, for consistency) you're about to spoil in your comment if it's big. People who know extra stuff (my betas and people who have requested specific spoilers) should keep mum about unpublished information they have. If you wish to join the ranks of the betas or the spoiled, contact me individually.

(nods) That intuition is shared by many.
Ironically, the reversal test often fails, though: that is, it's not uncommon for people to intuit that a copy of X that lacks trait Y isn't really X, while at the same time intuiting that if X were to lose trait Y, it would still be X.
Identity is complicated.
For my own part, I think the terms "memory" and "personality trait" stop being clearly distinguishable from one another, when you drill down into implementation. Our brains create persistent data structures in response to events, and those data structures underlie both personality and memory. That distinction is functional -- we distinguish a personality trait from a memory based on how we behave, not based on any kind of awareness of the underlying data structures. And it's not at all obvious (nor even likely) that all the things we call "memory" share a common data structure, or that they don't share underlying data structures with what we call "personality."
Then again, I feel the same way about "identity."
To understand an elephant is to realize that recognizing the difference between trunk and tusk is not the end of the story.
So I would expect a psychic power that interacted with those data structures not to respect the boundaries between "memory" and "personality" in any kind of intuitive way.
That said, many witch-powers in this fictional world do respect those intuitive boundaries, so it's not clear what any of the above actually has to do with events in the story.
