1) become better-versed in possible Gricean maneuvers w.r.t. Ross's puzzle. In particular, for the wide-scope version, a relevant alternative to the asserted
(Might p) v (Might q)
is
(Might p) & (Might q)
....in other words, why not just say the implicature? It's not any more complicated!
[initial response: ooh, damn. True dat.]
2) Understand Kratzer's semantics for modals. This has a conversational background parameter f in the index. Let's understand indices and contexts! Woo!
3) I never got to ask about propositions. Still not sure what they are. Definitely the case that in a tensed language there are tensed propositions: functions from world-time pairs to truth-values (in other words: you need both a world and a time to get to a truth-value.)
4) Regarding tensed propositions: consider the philosopher who thinks we don't believe tensed things. Therefore we need to believe eternal things. (Therefore there has to be hidden syntactic material in sentences like "Joe is fat"?...maybe.) Then the things we believe are not propositions? At least, according to the eternalist, they are not. "Nixon is president" does not have a truth-value/is not a proposition; it is a function from times to propositions.
