I agree with both statements.

This would make false statements true of the real world by virtue of
their being imagined. That's a job for {dahi}.

None of this strikes me as an impediment to defining meaning within
the framework of a given epistemology.

Lojban communication gets by fine without all this kerfuffle about
truth and worlds. That only becomes relevant when we delve into
literal, grammaticall-determined meaning, armed with truth-conditional
methods.

I don't claim to be able to do it actually, but I do claim to be able
to do it hypothetically, which is all that is necessary.

Okay. What is the syntax of {da cerlok. xolmes}?
