hey Kea...
pardon my ignorance but as non technically as you possibly can, could you give us a rundown on category theory, what some of it's predictions are and how it ties into string theory and the background dependence thing ???
...please

If Kea can't offer anything herself, perhaps she knows of a very simple category theories for dummies paper somewhere. I've looked for Lawvere and a few others she has mentioned, but I've yet to come up with anything that is non technical. Or better yet, gives some deeper metaphysical justification for category being ultimate - like the sort of arguments that used to bandied about for set theory.
Anything on this site for a start?
