This is true, but once we've got to the easy part we can
linguistically model human reasoning, and until we get there 
we can't. Thereafter the problem shifts from a linguistic
problem to a purely philosophical one. So long as Lojban
can quantify over *'relevant'* possible worlds, then the
problem for Lojban is solved, and the issue of what
defines 'relevant' can be handed over to the philosophers
or the psychologists.
