But where does the epistemology/metaphysics come in?  Your English has left
them out, and I am sufficiently Lojbanized in my English meanings that
"x2 is false" is hopelessly ambiguous to me barring a lot more context.
Was x2 false at time X?  Was x2 at time X false?  Were these false by
x1's worldview/epistemology/choice of metaphysics?  Unless the speaker
is explicitly brought into the bridi, I think that the speaker's metaphysics
should be irrelevant  (I'll amend that - the speaker may be brouyght into
the text at large via context, in which case I would consider the speaker's
world view to be implicitly relevant.

BTW, if I understand what pc wrote, I agree with all he said.
