Could a possible world be exhaustively described using only indexicals? Is there a unique bijection between indexical and non-indexical world descriptions or not? Does this make any sense? What does an indexical sentence even look like formally? Cf writing the book of the world/unique complete descriptions questions?
Practical implications re infra-bayesianism?
Model theory stuff?
How do you model indexicals in information theory? Is there an analogy to mary the colour scientist learning indexical information only and this isnt in the book of the world or something? What about information being limited to lightspeed, this mustnt apply to indexical info, or maybe it kinda does all the relevant info movement is in your head through neurons, not between the outsude world and your mental representations? Does this mean it isnt really info in the entropy/mentaculus sense?
Off this, can you analyse the a posteriori/apriori distinction in this way? Probably not I guess, since all the information processing within your head must still be sublight speed. Maybe there’s something there still somehow re what the information/belief is reliably linked to having to be structural properties of your brain for it to be a priori or analytic or something idk.
This cluster of bayesianism/information theory/apriori-aposteriori/analytic-synthetic stuff is interesting. What was scott aaronsons take here?
Can there be any relevance with our universe lacking reflectional symmetry? Almost certainly not? Kantian angle here?
